AN OVERVIEW OF THE FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.



WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS?

The portfolio managers look for stocks of companies they believe will increase
in value over time, using investment strategies developed by American Century.
In implementing these strategies, the portfolio managers make their investment
decisions based primarily on their analysis of individual companies, rather than
on broad economic forecasts. Management of the fund is based on the belief that,
over the long term, stock price movements follow growth in earnings, revenues
and/or cash flow.

The portfolio managers use a variety of analytical research tools and techniques
to identify the stocks of larger-sized companies that meet their investment
criteria. Under normal market conditions, the fund's portfolio will primarily
consist of securities of companies whose earnings or revenues are not only
growing, but growing at an accelerating pace.

The fund's principal risks include

*  GROWTH STOCKS - Investments in growth stocks may involve special risks and
   their prices may fluctuate more dramatically than the overall stock market.

*  FOREIGN SECURITIES - A fund may invest in foreign securities, which can be
   riskier than investing in U.S. securities.

*  MARKET RISK - The value of a fund's shares will go up and down based on
   the performance of the companies whose securities it owns and other factors
   generally affecting the securities market.

*  PRICE VOLATILITY - The value of a fund's shares may fluctuate
   significantly in the short term.

*  PRINCIPAL LOSS - At any given time your shares may be worth less than the
   price you paid for them. In other words, it is possible to lose money by
   investing in the fund.

A more detailed description of the fund's investment strategies and risks may be
found under the heading OBJECTIVES, STRATEGIES AND RISKS which begins on page 8.

        [graphic of triangle]

        AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED
        OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR
        ANY OTHER GOVERNMENT AGENCY.

FUND PERFORMANCE HISTORY

Annual Total Returns

The following bar chart shows the performance of the fund's Investor Class
shares for each of the last 10 calendar years. It indicates the volatility of
the fund's historical returns from year to year. Account fees and sales charges,
if applicable, are not reflected in the chart below. If they had been included,
returns would be lower than those shown. The returns of the fund's other classes
will differ from those shown in the chart, depending on the expenses of those
classes.



INVESTOR CLASS



The highest and lowest quarterly returns for the periods reflected in the bar
chart are:


                          HIGHEST                             LOWEST
--------------------------------------------------------------------------------
Ultra                     32.09% (4Q 1999)                    -17.49% (1Q 2001)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment. Because the B Class
(which commenced operations on September 28, 2007) does not have investment
results for a full calendar year, it is not included.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------
3


After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for the Investor Class shares. After-tax returns for the
other share classes will vary.

The benchmarks are unmanaged indices that have no operating costs and are
included in each table for performance comparison. The Russell 1000 Growth Index
measures the performance of those Russell 1000 Index companies (the 1,000
largest of the 3,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values. The S&P 500 Index is a market value-weighted index of the stocks
of 500 publicly traded U.S. companies chosen for market size, liquidity, and
industry group representation that are considered to be leading firms in
dominant industries.

The table above reflects a deduction for charges payable upon redemption. You
would pay the following expenses if you did not redeem your shares and thus did
not incur such charges:

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the portfolio managers
make their investment decisions based primarily on their analysis of individual
companies, rather than on broad economic forecasts. Management of the fund is
based on the belief that, over the long term, stock price movements follow
growth in earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies whose earnings and
revenues are not only growing, but growing at an accelerating pace. This
includes companies whose growth rates, although still negative, are less
negative than prior periods, and companies whose growth rates are expected to
accelerate. Other analytical techniques help identify additional signs of
business improvement, such as increasing cash flows, or other indications of the
relative strength of a company's business. In addition to accelerating growth
and other signs of business improvement, the fund also considers companies
demonstrating price strength relative to their peers. These techniques help the
portfolio managers buy or hold the stocks of companies they believe have
favorable growth prospects and sell the stocks of companies whose
characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, options, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the managers believe this strategy provides substantial appreciation
potential over the long term, in the short term it can create a significant
amount of share price volatility. This volatility can be greater than that of
the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent a fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring a
fund's style, the fund's gains may not be as big as, or its losses may be bigger
than, other equity funds using different investment styles.

The value of a fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities a fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

STEVE LURITO

Mr. Lurito, Senior Vice President and Chief Investment Officer, U.S. Growth
Equity, has been a member of the team that manages the fund since August 2007.
He joined American Century in July 2007. From April 2006 to June 2007, he was
the chief investment officer at MUUS Asset Management. From March 2004 to
January 2006, he was the director of small cap research, senior portfolio
manager and managing director at Forstmann Leff Associates. From January 2002 to
December 2003, he was president at Arlington Capital Management. He has a
bachelor's degree from the University of Virginia in Charlottesville and an MBA
from The Wharton School of Business, University of Pennsylvania.

TOM TELFORD

Mr. Telford, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since June 2006. He joined American Century in July 1996
and became a portfolio manager in February 2000. He has a bachelor's degree in
business administration from Southern Methodist University and an MBA from The
Wharton School of Business, University of Pennsylvania. He is a CFA
charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the

From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                                  AMOUNT PAID

--------------------------------------------------------------------------------
$250,000 - $499,999         2.50%              2.56%              2.00%

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase, of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any American Century fund (excluding 529 account
assets and certain assets in money market accounts) to reduce your A Class sales
charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15


For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any American
Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any American Century fund you intend to make over a 13-month
period to determine the applicable sales charge. At your request, existing
holdings may be combined with new purchases and sales charge amounts may be
adjusted for purchases made within 90 days prior to our receipt of the Letter of
Intent. Capital appreciation, capital gains and reinvested dividends earned
during the Letter of Intent period do not apply toward its completion. A portion
of your account will be held in escrow to cover additional A Class sales charges
that will be due if your total investments over the 13-month period do not
qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Shares purchased in accounts that held Advisor Class shares of this fund
   prior to September 4, 2007

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.

B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------
17


CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market value
      for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market value
      for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.

EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.


------
18





BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program
accounts and/or fee-based accounts                                    No minimum

--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.


------
20


ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

        [graphic of triangle]




        A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.


------
21


We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is


------
22


significant relative to a fund's net assets, the fund may incur trading costs
that are higher than necessary as securities are first purchased then quickly
sold to meet the redemption request. In such case, the fund's performance could
be negatively impacted by the increased trading costs created by short-term
trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

24





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

        [graphic of triangle]

        CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
        SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, to your home address or to another
person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

        [graphic of triangle]



        QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
        THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED
        THAT THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions-including exchanges to other American Century funds-are subject
to capital gains tax. The table above can provide a general guide for your
potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
28


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the fund's portfolio will primarily consist of securities of companies demonstrating business improvement. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each of the last 10 calendar years. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                          HIGHEST                             LOWEST
--------------------------------------------------------------------------------
Growth                    23.62% (4Q 1999)                     -19.33% (1Q 2001)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for the Investor Class shares. After-tax returns for the
other share classes will vary.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the portfolio managers
make their investment decisions based primarily on their analysis of individual
companies, rather than on broad economic forecasts. Management of the fund is
based on the belief that, over the long term, stock price movements follow
growth in earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies demonstrating
business improvement. Analytical indicators helping to identify signs of
business improvement could include accelerating earnings or revenue growth
rates, increasing cash flows, or other indications of the relative strength of a
company's business. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, options, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund and the NT
Growth fund as well as certain assets of other clients of the advisor outside
the American Century fund family (such as subadvised funds and separate
accounts) that use very similar investment teams and strategies. The use of
strategy assets, rather than fund assets, in calculating the fund's fee rate
could allow the fund to realize scheduled cost savings more quickly. However, it
is possible that the fund's strategy assets will not include assets of other
client accounts or that any such assets may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

GREGORY J. WOODHAMS

Mr. Woodhams, Vice President and Senior Portfolio Manager, has been a member of
the team that manages the fund since he joined American Century in September
1997. He has a bachelor's degree in economics from Rice University and an M.A.
in economics from the University of Wisconsin. He is a CFA charterholder.

E. A. PRESCOTT LEGARD

Mr. LeGard, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since March 1999. He has a bachelor's degree in economics
from DePauw University. He is a CFA charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

Class shares of the American Century Diversified Bond fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
we may charge you a $12.50 semiannual account maintenance fee if the value of
those shares is less than $10,000. We will determine the amount of your total
eligible investments twice per year, generally the last Friday in October and
April. If the value of those investments is less than $10,000 at that time, we
will automatically redeem shares in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In
determining your total eligible investment amount, we will include your

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's R and Advisor Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's Advisor Class is
intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS,
   INSURANCE COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts

--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that


------
14


your purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that you may incur tax liability as a
result of the redemption. For Institutional Class shares, we reserve the right
to convert your shares to Investor Class shares of the same fund. The Investor
Class shares have a unified management fee that is 0.20% higher than the
Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.


------
15


MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. Each fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.


------
16



American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
17





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
18


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
19


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
20


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, R Class and Advisor Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences between the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; and (e) the Institutional Class may provide
for automatic conversion from that class into shares of the Investor Class of
the same fund.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. The fund's Advisor Class and R Class shares have a 12b-1 plan. The
plans provide for the fund to pay annual fees of 0.50% for R Class and 0.25% for
Advisor Class to the distributor for distribution and individual shareholder
services, including past distribution services. The distributor pays all or a
portion of such fees to the financial intermediaries that make the classes
available. Because these fees may be used to pay for services that are not
related to prospective sales of the fund, each class will continue to make
payments under its plan even if it is closed to new investors. Because these
fees are paid out of the fund's assets on an ongoing basis, over time these fees
will increase the cost of your investment and may cost you more than paying
other types of sales charges. For additional information about the plans and
their terms, see MULTIPLE CLASS STRUCTURe in the statement of additional
information.



------
22



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers primarily look for stocks of medium-sized and smaller companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * MID CAP STOCKS - The fund invests in mid-sized and smaller companies which may present greater opportunities for capital growth than larger companies, but may be more volatile and subject to greater risk. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [GRAPHIC OF TRIANGLE] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each of the last 10 calendar years. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                          HIGHEST                              LOWEST
--------------------------------------------------------------------------------
Vista                     72.22% (4Q 1999)                     -27.52% (3Q 1998)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------
3


After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for the Investor Class shares. After-tax returns for the
other share classes will vary.

The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell Midcap Growth Index
measures the performance of those Russell Midcap Index companies (the 800
smallest of the 1,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers primarily look for stocks of medium-sized and smaller
companies they believe will increase in value over time, using an investment
strategy developed by American Century. In implementing this strategy, the
portfolio managers use a bottom-up approach to stock selection. This means that
the managers make their investment decisions based primarily on their analysis
of individual companies, rather than on broad economic forecasts. Management of
the fund is based on the belief that, over the long term, stock price movements
follow growth in earnings and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. In addition to accelerating growth, the fund also considers
companies demonstrating price strength relative to their peers. These techniques
help the portfolio managers buy or hold the stocks of companies they believe
have favorable growth prospects and sell the stocks of companies whose
characteristics no longer meet their criteria.

The fund will usually purchase common stocks of companies that are medium-sized
and smaller at the time of purchase, but it can purchase other types of
securities as well. When determining the size of a company, the portfolio
managers will consider, among other factors, the capitalization of the company
and the amount of revenues as well as other information they obtain about the
company.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the portfolio
managers believe it is prudent, the fund may invest a portion of its assets in
debt securities, options, preferred stock and equity-equivalent securities, such
as convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.


------
7


In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The fund generally invests in mid-size and smaller companies, which may be more
volatile and subject to greater short-term risk. Smaller companies may have
limited financial resources, product lines and markets, and their securities may
trade less frequently and in more limited volumes than securities of larger
companies. In addition, smaller companies may have less publicly available
information.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

The fund's portfolio turnover may be high. This could result in relatively high
commission costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

     MANAGEMENT FEE WAS 1.00% OF AVERAGE NET ASSETS.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

GLENN A. FOGLE

Mr. Fogle, Senior Vice President and Senior Portfolio Manager, has been a member
of the team that manages the fund since joining American Century in September
1990. He has a bachelor's degree in business administration (management) and an
MBA in finance from Texas Christian University. He is a CFA charterholder.

BRADLEY J. EIXMANN

Mr. Eixmann, Portfolio Manager, has been a member of the team that manages the
fund since joining American Century in July 2002 as an investment analyst. He
became a Portfolio Manager in February 2007. He has a bachelor's degree in
managerial studies and economics from Rice University and an MBA in finance from
the University of Texas. He is a CFA charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's R and Advisor Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's Advisor Class is
intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding plan types, please see BUYING AND SELLING FUND SHARES in the statement
of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
   COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts

--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.


   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.


------
14


However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that you may incur tax liability as a
result of the redemption. For Institutional Class shares, we reserve the right
to convert your shares to Investor Class shares of the same fund. The Investor
Class shares have a unified management fee that is 0.20% higher than the
Institutional Class.



------
15


SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. Each fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.


------
16


Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
17





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
18


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
   STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
19


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
20


The tax status of any distributions of capital gains is determined by how long a
fund held the underlying security that was sold, not by how long you have been
invested in the fund, or whether you reinvest your distributions in additional
shares or take them in cash. For taxable accounts, American Century or your
financial intermediary will inform you of the tax status of fund distributions
for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
21


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, R Class and Advisor Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; and (e) the Institutional Class may provide
for automatic conversion from that class into shares of the Investor Class of
the same fund.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. The fund's Advisor Class and R Class shares have a 12b-1 plan. The
plans provide for the fund to pay annual fees of 0.50% for R Class and 0.25% for
Advisor Class to the distributor for distribution and individual shareholder
services, including past distribution services. The distributor pays all or a
portion of such fees to the financial intermediaries that make the classes
available. Because these fees may be used to pay for services that are not
related to prospective sales of the fund, each class will continue to make
payments under its plan even if it is closed to new investors. Because these
fees are paid out of the fund's assets on an ongoing basis, over time these fees
will increase the cost of your investment and may cost you more than paying
other types of sales charges. For additional information about the plans and
their terms, see MULTIPLE CLASS STRUCTURE in the statement of additional
information.



------
22



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGY AND PRINCIPAL RISKS? The portfolio managers look for stocks of medium-sized and smaller companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund's principal risks include: * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * MID CAP STOCKS - The fund invests in mid-sized and smaller companies which may present greater opportunities for capital growth than larger companies, but may be more volatile and subject to greater risk. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [graphic of triangle] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 6. [graphic of triangle] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's shares for each of the last 10 calendar years. It indicates the volatility of the fund's historical returns from year to year. Account fees are not reflected in the chart below. If they had been included, returns would be lower than those shown. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                              HIGHEST                          LOWEST
--------------------------------------------------------------------------------
Giftrust Fund                 56.31% (4Q 1999)                 -35.13% (4Q 2000)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways.

Return Before Taxes shows the actual change in the value of fund shares over the
periods shown, but does not reflect the impact of taxes on fund distributions or
the sale of fund shares. The two after-tax returns take into account taxes that
may be associated with owning fund shares. Return After Taxes on Distributions
is a fund's actual performance, adjusted by the effect of taxes on distributions
made by the fund during the period shown. Return After Taxes on Distributions
and Sale of Fund Shares is further adjusted to reflect the tax impact on any
change in the value of fund shares as if they had been sold on the last day of

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of medium-sized and smaller companies
they believe will increase in value over time, using an investment strategy
developed by American Century. In implementing this strategy, the portfolio
managers use a bottom-up approach to stock selection. This means that the
managers make their investment decisions based primarily on their analysis of
individual companies, rather than on broad economic forecasts. Management of the
fund is based on the belief that, over the long term, stock price movements
follow growth in earnings and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

The fund will usually purchase common stocks of U.S. and foreign companies that
are medium-sized and smaller at the time of purchase, but it can purchase other
types of securities as well. When determining the size of a company, the
portfolio managers will consider, among other factors, the capitalization of the
company and the amount of revenues as well as other information they obtain
about the company.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the portfolio
managers believe it is prudent, the fund may invest a portion of its assets in
debt securities, options, preferred stock and equity-equivalent securities, such
as convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations, except convertible debt securities, which may be
rated below investment grade. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

If the companies in which the fund invests are successful, these companies may
grow into large-sized companies. In addition, if the portfolio managers
determine


------
6


that the availability of medium-sized and smaller companies in which to invest
is not adequate to meet the fund's investment needs, the portfolio managers may
invest in large-sized companies.

The Giftrust Fund is intended for investors who want to give a one-time gift to
another individual, but want that gift to have the potential to grow over time
(at least 18 years) in an aggressive equity fund that seeks long-term capital
growth. Investors wanting to make such a gift must be willing to give up control
over the gift and accept the risks associated with the fund's investment
strategy.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

The minimum term of a Giftrust established on or after August 1, 2002, is 18
years and the maximum term is 65 years. By the terms of the trust, a gift is
irrevocable and will be held in the trust until its term expires.

        [graphic of triangle]

        EFFECTIVE JANUARY 1, 2005, A CHANGE IN MISSOURI LAW MAKES IT
        POSSIBLE TO TERMINATE A GIFTRUST EARLY UNDER CERTAIN CIRCUMSTANCES
        WITH THE CONSENT OF THE GRANTOR AND ALL BENEFICIARIES. MORE INFORMATION
        ABOUT HOW THIS CHANGE MAY AFFECT THE RIGHTS OF GIFTRUST BENEFICIARIES
        IS AVAILABLE AT AMERICANCENTURY.COM.

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock markets.

The fund generally invests in medium-sized and smaller companies, which may be
more volatile and subject to greater short-term risk. Smaller companies may have
limited financial resources, product lines and markets, and their securities may
trade less frequently and in more limited volumes than the securities of larger
companies. In addition, smaller companies may have less publicly available
information.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the managers believe this strategy provides substantial appreciation
potential over the long term, in the short term it can create a significant
amount of share price volatility. This volatility can be greater than that of
the average stock fund.

The fund's portfolio turnover may be high. This could result in relatively high
commission costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. To the
extent the fund invests in foreign securities, the overall risk of the fund
could be affected. Foreign investment involves additional risks, including
fluctuations in currency exchange rates, less stable political and economic
structures, reduced availability of public information, and lack of uniform
financial reporting and regulatory practices similar to those that apply in the
United States. These factors make investing in foreign securities generally
riskier than investing in U.S. stocks.


------
7


Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located in
foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These changes
may be magnified by the countries' emergent financial markets, resulting in
significant volatility to investments in these countries. These countries also
may lack the legal, business and social framework to support securities markets.

The fund's performance also may be affected by investments in initial public
offerings (IPOs). The impact of IPOs on the fund's performance depends on the
strength of the IPO market and the size of the fund. IPOs may have less impact
on the fund's performance as its assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of its investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

DAVID M. HOLLOND

Mr. Hollond, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since February 2007. He joined American Century in 1998
and became a portfolio manager in March 2004. He has a bachelor's degree in
Russian and economics from Grinnell College, a master's degree in economics from
the University of Wisconsin, a master's degree in international studies from the
University of Pennsylvania and an MBA in finance from The Wharton School,
University of Pennsylvania.

GREG WALSH

Mr. Walsh, Portfolio Manager, has been a member of the team that manages the
fund since joining American Century in July 2003 as an investment analyst. He
became a portfolio manager in February 2008. He has a bachelor of art degree in
economics and accounting from Claremont McKenna College and an MBA from The
Wharton School, University of Pennsylvania.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objective of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

ACCOUNT MAINTENANCE FEE

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
we may charge you a $12.50 semiannual account maintenance fee if the value of
those shares is less than $10,000. We will determine the amount of your total
eligible investments twice per year, generally the last Friday in October and
April. If the value of those investments is less than $10,000 at that time, we
will redeem shares automatically in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In
determining your total eligible investment amount, we will include your
investments in all PERSONAL ACCOUNTS (including American Century Brokerage
accounts) registered under your Social Security number. We will not charge the
fee as long as you choose to manage your accounts exclusively online. You may
enroll for exclusive online account management on our Web site. To find out more
about exclusive online account management, visit
www.americancentury.com/info/demo.

        [graphic of triangle]

        PERSONAL ACCOUNTS INCLUDE INDIVIDUAL ACCOUNTS, JOINT ACCOUNTS, UGMA/UTMA
        ACCOUNTS, PERSONAL TRUSTS, COVERDELL EDUCATION SAVINGS ACCOUNTS, IRAS
        (INCLUDING TRADITIONAL, ROTH, ROLLOVER, SEP-, SARSEP- AND SIMPLE-IRAS),
        AND CERTAIN OTHER RETIREMENT ACCOUNTS. IF YOU HAVE ONLY BUSINESS,
        BUSINESS RETIREMENT, EMPLOYER-SPONSORED OR AMERICAN CENTURY BROKERAGE
        ACCOUNTS, YOU ARE CURRENTLY NOT SUBJECT TO THIS FEE, BUT YOU MAY BE
        SUBJECT TO OTHER FEES.

REDEMPTIONS

Giftrust shares ordinarily may not be redeemed until the Giftrust matures.
However, effective January 1, 2005, a change in Missouri law makes it possible
to terminate a Giftrust early under certain circumstances with the consent of
the grantor and all beneficiaries. This requires a completed Giftrust Options
Form, which is available online at americancentury.com or by calling a Service
Representative at 1-800-345-2021. Your redemption proceeds will be calculated
using the NET ASSET VALUE (NAV) next determined after we receive your
transaction request in good order.

        [graphic of triangle]




        A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment in a matured


------
13


Giftrust, there is a seven-day holding period before we will release redemption
proceeds from those shares, unless you provide us with satisfactory proof that
your purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. In addition, we reserve the right to
honor certain redemptions with securities, rather than cash, as described in the
next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, the beneficiary redeems matured Giftrust shares
worth more than $250,000 (or 1% of the value of the fund's assets if that amount
is less than $250,000), we reserve the right to pay part or all of the
redemption proceeds in excess of this amount in readily marketable securities
instead of in cash. The portfolio managers would select these securities from
the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, the beneficiary may have
to pay brokerage or other transaction costs to convert the securities to cash.

If the redemption exceeds this limit and the beneficiary would like to avoid
being paid in securities, he or she should provide us with an unconditional
instruction to redeem at least 15 days prior to the date on which the redemption
transaction is to occur. The instruction must specify the dollar amount or
number of shares to be redeemed and the date of the transaction. This minimizes
the effect of the redemption on the fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If the matured Giftrust balance falls below the minimum initial investment
amount for any reason other than as a result of market fluctuation, American
Century reserves the right to redeem the shares in the account and send the
proceeds to the beneficiary's address of record. Prior to doing so, we will
notify the beneficiary and allow 90 days to meet the minimum. Please note that
the beneficiary may incur tax liability as a result of the redemption.

SIGNATURE GUARANTEES

A signature guarantee-which is different from a notarized signature-is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions:

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account

*  You are transferring ownership of an account over $100,000

*  You change your address and request a redemption over $100,000 within 15
   days

*  You change your bank information and request a redemption within 15 days

We reserve the right to require a signature guarantee for other transactions at
our discretion.


------

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of the fund.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
funds' Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.


------
15


To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-800-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
17


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

        [graphic of triangle]

        CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
        SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

TAXES

The following is only a summary of the tax law effects of establishing a
Giftrust. The tax laws applicable to trusts in general are quite complex. You
should consider consulting your tax advisor or attorney before opening a
Giftrust. Distributions by the fund will impact the amount of taxes paid by a
Giftrust. Distributions may consist of dividend and interest income the fund
receives on its investments or capital gains it generates as a result of the
sale of its securities.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of a fund, in which
case distributions of income are taxed as long-term capital gains.

        [graphic of triangle]



        QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM
        THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED
        THAT THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.

The tax status of any distribution of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long a Giftrust
has been in existence. No federal income tax is due from a Giftrust unless its
income exceeds approximately $100 in a year. Distributions also may be subject
to state and local taxes. The trustee files all state and federal tax returns
and pays the taxes by redeeming the appropriate number of shares from the trust.
A $10 fee is charged to a Giftrust for each year a tax return is filed. This fee
also is paid by redeeming shares from the Giftrust.


------
19


Taxes on Transactions

Redemptions by beneficiaries once a Giftrust has matured or been terminated
early- including exchanges to other American Century funds - are subject to
capital gains tax. Based on current tax law, which is subject to change, gains
or losses would be treated as either short-term or long-term capital gains or
losses.

Gift Taxes

Establishing a Giftrust (and making future contributions) is considered a gift
of a future interest under the federal tax code. That means the gift does not
qualify for the annual gift tax exclusion of $12,000 (indexed for inflation). If
you establish a Giftrust, you must file a United States Gift Tax Return (Form
709). For Giftrusts established before August 1, 2002, if the grantor makes
additional gifts in subsequent years, a Gift Tax Return must be filed for each
year's gift(s). No gift tax is payable until your cumulative lifetime gifts
exceed the exemption equivalent of $1 million. Each gift reduces the exemption
equivalent that would otherwise be available in the future.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers for the fund use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the fund's portfolio will primarily consist of securities of companies whose earnings or revenues are not only growing, but growing at an accelerating pace. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 8. [graphic of triangle] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each of the last 10 calendar years. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                          HIGHEST                             LOWEST

--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
periods shown, but does not reflect the impact of taxes on fund distributions or
the sale of fund shares. The two after-tax returns take into account taxes that
may be associated with owning fund shares. Return After Taxes on Distributions
is a fund's actual performance, adjusted by the effect of taxes on distributions
made by the fund during the periods shown. Return After Taxes on Distributions
and Sale of Fund Shares is further adjusted to reflect the tax impact on any
change in the value of fund shares as if they had been sold on the last day of
the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for Investor Class shares. After-tax returns for other
share classes will vary.

EXAMPLE

The examples in the tables below are intended to help you compare the costs of
investing in the fund with the costs of investing in other mutual funds. Of
course, your actual costs may be higher or lower. Assuming you . . .

*  redeem all of your shares at the end of the periods shown below

*  earn a 5% return each year

*  incur the same operating expenses as shown above

. . . your cost of investing in the fund would be:

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the managers make their
investment decisions based primarily on their analysis of individual companies,
rather than on broad economic forecasts. Management of the fund is based on the
belief that, over the long term, stock price movements follow growth in
earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies whose earnings or
revenues are not only growing, but growing at an accelerating pace. This
includes companies whose growth rates, although still negative, are less
negative than prior periods, and companies whose growth rates are expected to
accelerate. Other analytical techniques help identify additional signs of
business improvement, such as increasing cash flows, or other indications of the
relative strength of a company's business. These techniques help the portfolio
managers buy or hold the stocks of companies they believe have favorable growth
prospects and sell the stocks of companies whose characteristics no longer meet
their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
a fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the managers believe this strategy provides substantial appreciation
potential over the long term, in the short term it can create a significant
amount of share price volatility. This volatility can be greater than that of
the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent a fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring a
fund's style, the fund's gains may not be as big as, or its losses may be bigger
than, other equity funds using different investment styles.

The value of a fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities a fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

     2007, THE MANAGEMENT FEE WAS 1.00% OF AVERAGE NET ASSETS.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

KEITH LEE

Mr. Lee, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since October 2001. He initially joined American Century
in August 1998 and rejoined October 2001 as a senior investment analyst. He
became a portfolio manager in June 2003. He has a bachelor of science degree in
industrial engineering from Columbia University. He is a CFA charterholder.

MICHAEL LI

Dr. Li, Portfolio Manager, has been a member of the team that manages the fund
since July 2003. He joined American Century in February 2002 as an investment
analyst and became a portfolio manager in February 2006. Before joining American
Century, he attended the Wharton School of Business, University of Pennsylvania,
where he obtained his MBA. He also has a bachelor of science from the University
of Science and Technology of China and a Ph.D. from the University of Michigan.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

       [graphic of triangle]

       FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
       COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                             AMOUNT PAID TO

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15



For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less commissionable shares in the money market funds, in any
share class of any American Century fund to qualify for a reduced A Class sales
charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Shares purchased in accounts that held Advisor Class shares of this fund
   prior to September 4, 2007

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.

B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------
17


CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market value
      for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market value
      for C Class shares

*  distributions from IRAs due to attainment of age 59 1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70 1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.


------
18


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

Broker-dealer sponsored wrap program
accounts and/or fee-based accounts                                    No minimum

Coverdell Education Savings Account (CESA)                            $2,000(1)
--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.


------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

       [graphic of triangle]




       A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.


------
21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
22


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.



------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

       [graphic of triangle]

       CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS STOCK,
       FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of its investment securities. Distributions of income are taxed as
ordinary income, unless they are designated as QUALIFIED DIVIDEND INCOME and you
meet a minimum required holding period with respect to your shares of the fund,
in which case distributions of income are taxed as long-term capital gains.


       [graphic of triangle]



       QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE STOCK
       OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND
       HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes, and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.



------
29



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The fund's portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the fund's portfolio will primarily consist of securities of companies demonstrating business improvement. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them.

Average Annual Total Returns

The following table shows the average annual total returns of the fund's A Class
shares calculated three different ways. Additional tables show the average
annual total returns of the fund's other share classes calculated before the
impact of taxes. Returns assume the deduction of all sales loads, charges and
other fees associated with a particular class. Your actual returns may vary
depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for A Class shares. After-tax returns for other share
classes will vary.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the managers make their
investment decisions based primarily on their analysis of individual companies,
rather than on broad economic forecasts. Management of the fund is based on the
belief that, over the long term, stock price movements follow growth in
earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies demonstrating
business improvement. Analytical indicators helping to identify signs of
business improvement could include accelerating earnings or revenue growth
rates, increasing cash flows, or other indications of the relative strength of a
company's business. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.


------

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the managers believe this strategy provides substantial appreciation
potential over the long term, in the short term it can create a significant
amount of share price volatility. This volatility can be greater than that of
the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring a
fund's style, the fund's gains may not be as big as, or its losses may be bigger
than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, it is possible that the fund's
strategy assets will not include assets of other client accounts or that any
such assets may not be sufficient to result in a lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

GREGORY J. WOODHAMS

Mr. Woodhams, Vice President and Senior Portfolio Manager, has been a member of
the team that manages the fund since its inception in February 2004. He joined
American Century in September 1997 and became a portfolio manager in June 1998.
He has a bachelor's degree in economics from Rice University and an M.A. in
economics from the University of Wisconsin. He is a CFA charterholder.

E. A. PRESCOTT LEGARD

Mr. LeGard, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since its inception in February 2004. He joined American
Century in March 1999 and became a portfolio manager in April 2000. He has a
bachelor's degree in economics from DePauw University. He is a CFA
charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
   COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                              AMOUNT PAID

--------------------------------------------------------------------------------
$100,000 - $249,999       3.75%            3.90%              3.25%
--------------------------------------------------------------------------------
$250,000 - $499,999       2.50%            2.56%              2.00%
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15



For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.


------
16




REDEMPTION DURING                         CDSC AS A % OF ORIGINAL PURCHASE PRICE

--------------------------------------------------------------------------------
2nd year                                  4.00%
--------------------------------------------------------------------------------
3rd year                                  3.00%
--------------------------------------------------------------------------------
4th year                                  3.00%
--------------------------------------------------------------------------------
5th year                                  2.00%
--------------------------------------------------------------------------------
6th year                                  1.00%
--------------------------------------------------------------------------------
After 6th year                            None
--------------------------------------------------------------------------------


B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------
17


CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market
      value for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market
      value for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.

EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.


------
18





BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)
--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.


------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining investors.

21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
22


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS STOCK,
   FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, to your home address or to another
person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of its investment securities. Distributions of income are taxed as
ordinary income, unless they are designated as QUALIFIED DIVIDEND INCOME and you
meet a minimum required holding period with respect to your shares of the fund,
in which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE STOCK
   OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND HAS
   HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that the fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
28


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes, and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.



------
29



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. An Overview of the Fund WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the fund's portfolio will primarily consist of securities of companies demonstrating business improvement. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [graphic of triangle] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7.

It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes of shares will differ from those shown, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                               HIGHEST                         LOWEST
--------------------------------------------------------------------------------
Focused Growth                 6.19% (2Q 2007)                 -3.05% (2Q 2006)

Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Because the
Institutional, A, B, C and R Classes (which commenced operations September 28,
2007) do not have investment results for a full calendar year, they are not
included.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs.

The benchmark is an unmanaged index that has no operating costs and is included
in the table for performance comparison. The Russell 1000 Growth Index measures
the performance of those Russell 1000 Index companies (the 1,000 largest of the
3,000 largest publicly traded U.S. companies, based on total market
capitalization) with higher price-to-book ratios and higher forecasted growth
rates. The blended index combines two widely known indices, the S&P 500 Index
and the Russell 1000 Growth Index, which are both weighted at 50%. The S&P 500
Index is a market value-weighted index of the stocks of 500 publicly traded U.S.
companies chosen for market size, liquidity, and industry group representation
that are considered to be leading firms in dominant industries.

EXAMPLE

The examples in the tables below are intended to help you compare the costs of
investing in the fund with the costs of investing in other mutual funds. Of
course, your actual costs may be higher or lower. Assuming you . . .

*  invest $10,000 in the fund

*  redeem all of your shares at the end of the periods shown below

*  earn a 5% return each year

*  incur the same operating expenses as shown above



. . . your cost of investing in the fund would be:

                           1 YEAR        3 YEARS        5 YEARS        10 YEARS

--------------------------------------------------------------------------------



The table above reflects a deduction for charges payable upon redemption. You
would pay the following expenses if you did not redeem your shares and thus did
not incur such charges:

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the portfolio managers
make their investment decisions based primarily on their analysis of individual
companies, rather than on broad economic forecasts. Management of the fund is
based on the belief that, over the long term, stock price movements follow
growth in earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies demonstrating
business improvement. Analytical indicators helping to identify signs of
business improvement could include accelerating earnings or revenue growth
rates, increasing cash flows, or other indications of the relative strength of a
company's business. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the portfolio
managers believe it is prudent, the fund may invest a portion of its assets in
debt securities, options, preferred stock and equity-equivalent securities, such
as convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.


------

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The fund's portfolio turnover rate also may be high. This could result in
relatively high commission costs, which could hurt the fund's performance, and
capital gains tax liabilities for the fund's shareholders.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, it is possible that the fund's
strategy assets will not include assets of other client accounts or that any
such assets may not be sufficient to result in a lower fee rate.

fund's investment advisory contract with the advisor is available in the fund's

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

GREGORY J. WOODHAMS

Mr. Woodhams, Vice President and Senior Portfolio Manager, has been a member of
the team that manages the fund since the fund's inception in February 2005. He
joined American Century in September 1997. He has a bachelor's degree in
economics from Rice University and an M.A. in economics from the University of
Wisconsin. He is a CFA charterholder.

JOE REILAND

Joe Reiland, Portfolio Manager, has been a member of the team that manages the
fund since its inception. He joined American Century in September 2000 as an
investment analyst and became a senior investment analyst in February 2004 and a
portfolio manager in February 2005. He has a bachelor's degree in business
administration from Washington University. He is a CFA charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.





FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

       [graphic of triangle]

       FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS,
       INSURANCE COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following chart provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS AND INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                           SALES CHARGE     AMOUNT PAID TO
                          SALES CHARGE     AS A % OF        FINANCIAL ADVISOR
                          AS A % OF        NET AMOUNT       AS A % OF
PURCHASE AMOUNT           OFFERING PRICE   INVESTED         OFFERING PRICE
--------------------------------------------------------------------------------
Less than $50,000         5.75%            6.10%            5.00%
--------------------------------------------------------------------------------
$50,000 - $99,999         4.75%            4.99%            4.00%
--------------------------------------------------------------------------------
$100,000 - $249,999       3.75%            3.90%            3.25%
--------------------------------------------------------------------------------
$250,000 - $499,999       2.50%            2.56%            2.00%
--------------------------------------------------------------------------------
$500,000 - $999,999       2.00%            2.04%            1.75%
--------------------------------------------------------------------------------
$1,000,000 - $3,999,999   0.00%            0.00%            1.00%(1)
--------------------------------------------------------------------------------
$4,000,000 - $9,999,999   0.00%            0.00%            0.50%(1)

$10,000,000 or more       0.00%            0.00%            0.25%(1)
--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase, of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
14


For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Shares purchased in accounts that held Advisor Class shares of this fund
   prior to September 4, 2007

*  Certain other investors as deemed appropriate by American Century


------
15


B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.



REDEMPTION DURING                         CDSC AS A % OF ORIGINAL PURCHASE PRICE
--------------------------------------------------------------------------------
1st year                                  5.00%
--------------------------------------------------------------------------------
2nd year                                  4.00%
--------------------------------------------------------------------------------
3rd year                                  3.00%
--------------------------------------------------------------------------------
4th year                                  3.00%
--------------------------------------------------------------------------------
5th year                                  2.00%
--------------------------------------------------------------------------------
6th year                                  1.00%
--------------------------------------------------------------------------------
After 6th year                            None
--------------------------------------------------------------------------------


B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.


------
16


CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).

CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market value
      for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market value
      for C Class shares

*  distributions from IRAs due to attainment of age 59 1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70 1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.


------
17


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

Broker-dealer sponsored wrap program accounts                         No minimum
and/or fee-based accounts
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)
--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.



------
19


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

       [graphic of triangle]




       A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.


------
20


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
21


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
24


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

       [graphic of triangle]

       CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
       SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
25


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

       [graphic of triangle]



       QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND
       FROM THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION,
       PROVIDED THAT THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
26


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment


------
28


advisory services to clients of the financial intermediaries; and (3) marketing
and promotional services, including business planning assistance, educating
personnel about the fund, and sponsorship of sales meetings, which may include
covering costs of providing speakers, meals and other entertainment. The
distributor may sponsor seminars and conferences designed to educate
intermediaries about the fund and may cover the expenses associated with
attendance at such meetings, including travel costs. These payments and
activities are intended to provide an incentive to intermediaries to sell the
fund by educating them about the fund and helping defray the costs associated
with offering the fund. The amount of any payments described by this paragraph
is determined by the advisor or the distributor, and all such amounts are paid
out of the available assets of the advisor and distributor, and not by you or
the fund. As a result, the total expense ratio of the fund will not be affected
by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. An Overview of the Fund WHAT ARE THE FUND'S INVESTMENT OBJECTIVES? The fund seeks long-term capital growth. Income is a secondary objective.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The fund looks for common stocks of companies that the fund's portfolio managers believe are priced attractively in relation to their earnings growth potential and estimated dividend production. The fund will generally invest in larger companies, although it may purchase shares in companies of other sizes. The fund also may invest in initial public offerings (IPOs). The fund's principal risks include * STYLE RISK - If at any time the market is not favoring the fund's style, the fund's gains may not be as big as, or its losses may be bigger than, other equity funds using different investment styles. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * IPO RISK - Although the fund's performance has historically benefited from investments in IPOs, this benefit may not be sustainable as the fund's assets grow and market conditions change. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 8. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's A Class shares for each full calendar year in the life of the class. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would have been lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. A CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

Average Annual Total Returns

The following table shows the average annual total returns of the fund's A Class
shares calculated three different ways. Additional tables show the average
annual total returns of the fund's other share classes calculated before the
impact of taxes. Returns assume the deduction of all sales loads, charges and
other fees associated with a particular class. Your actual returns may vary
depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
periods shown, but does not reflect the impact of taxes on fund distributions or
the sale of fund shares. The two after-tax returns take into account taxes that
may be associated with owning fund shares. Return After Taxes on Distributions
is a fund's actual performance, adjusted by the effect of taxes on distributions
made by the fund during the period shown. Return After Taxes on Distributions
and Sale of Fund Shares is further adjusted to reflect the tax impact on any
change in the value of fund shares as if they had been sold on the last day of
the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for A Class shares. After tax returns for other share
classes will vary.

EXAMPLE

The examples in the tables below are intended to help you compare the costs of
investing in the fund with the costs of investing in other mutual funds. Of
course, your actual costs may be higher or lower. Assuming you . . .

*  invest $10,000 in the fund

*  redeem all of your shares at the end of the periods shown below

*  earn a 5% return each year

*  incur the same operating expenses as shown above



. . . your cost of investing in the fund would be:

OBJECTIVES, STRATEGIES AND RISKS




WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

The fund seeks long-term capital growth. Income is a secondary objective.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?

The fund generally looks for common stocks that the fund's portfolio managers
believe are attractively priced relative to the companies' earnings growth
potential and dividend yields. In implementing this approach, the managers use
an investment methodology that focuses on stock-specific internal factors, such
as achievable earnings estimates, sustainable growth rates and dividend payouts.
Risk control measures implemented by the portfolio managers help to provide
diversification of securities and sectors within the fund. The fund will
generally invest in larger-sized companies, although it may invest in companies
of any size. The fund also may invest in initial public offerings (IPOs).

The fund's investment approach is expected to generate returns with a lower
level of price volatility than is associated with more aggressive investments.
As a result, the fund is designed to meet the needs of long-term investors who
seek capital growth but do not want the price volatility typically associated
with more aggressive growth strategies.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep at least 80% of the fund's assets
invested in EQUITY SECURITIES at all times. The fund may change this 80% policy
only upon 60 days' prior written notice to shareholders. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

   [GRAPHIC OF TRIANGLE]




   EQUITY SECURITIES INCLUDE COMMON STOCK, PREFERRED STOCK, AND
   EQUITY-EQUIVALENT SECURITIES, SUCH AS SECURITIES CONVERTIBLE INTO
   COMMON STOCK, STOCK FUTURES CONTRACTS OR STOCK INDEX FUTURES CONTRACTS.

When determining whether to sell a security, the portfolio managers consider
among other things, a security's price, whether a security's risk parameters
outweigh its return opportunities, general market conditions and any other
factor deemed relevant by the portfolio managers.


------
8


A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash equivalent securities or short-term debt securities. To the extent
the fund assumes a temporary defensive position it will not be pursing its
investment objectives.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

The impact of IPOs on the fund's performance depends on the strength of the IPO
market and the size of the fund. Although the fund's performance has
historically benefited from investments in IPOs, this benefit may not be
sustainable as the fund's assets grow and market conditions change.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring a
fund's style, the fund's gains may not be as big as, or its losses may be bigger
than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

JERRY SULLIVAN

Mr. Sullivan, Vice President and Portfolio Manager, has been a member of the
team that manages the fund since its inception in November 2004. He joined
American Century in February 2000 as a portfolio manager. He has a bachelor's
degree in political science from Columbia University and an MBA with a
concentration in finance and accounting from the Columbia University Graduate
School of Business.

ROBERT M. BROOKBY

Mr. Brookby, Portfolio Manager, has been a member of the team that manages the
fund since February 2005. He joined American Century in June 2000 as an
investment analyst and became a portfolio manager in February 2005. He has a
bachelor's degree in economics from Northwestern University and an MBA from
Harvard University.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS,
   INSURANCE COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                               AMOUNT PAID

--------------------------------------------------------------------------------
$100,000 - $249,999        3.75%            3.90%              3.25%
--------------------------------------------------------------------------------
$250,000 - $499,999        2.50%            2.56%              2.00%
--------------------------------------------------------------------------------
$500,000 - $999,999        2.00%            2.04%              1.75%
--------------------------------------------------------------------------------
$1,000,000 - $3,999,999    0.00%            0.00%              1.00%(1)

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15



For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less commissionable shares in the money market funds, in any
share class of any American Century fund to qualify for a reduced A Class sales
charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.


------
16




REDEMPTION DURING                         CDSC AS A % OF ORIGINAL PURCHASE PRICE
--------------------------------------------------------------------------------
1st year                                  5.00%
--------------------------------------------------------------------------------
2nd year                                  4.00%
--------------------------------------------------------------------------------
3rd year                                  3.00%
--------------------------------------------------------------------------------
4th year                                  3.00%
--------------------------------------------------------------------------------
5th year                                  2.00%
--------------------------------------------------------------------------------
6th year                                  1.00%
--------------------------------------------------------------------------------
After 6th year                            None
--------------------------------------------------------------------------------


B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------
17


CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market
      value for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market
      value for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.


------
18


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)
--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.



------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining investors.


------
21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of the fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
22


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by the fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gain                 Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions-including exchanges to other American Century funds-are subject
to capital gains tax. The table above can provide a general guide for your
potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

28


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes, and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.



------
29



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of medium-sized and smaller companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * MID CAP STOCKS - The fund invests in mid-sized and smaller companies which may present greater opportunities for capital growth than larger companies, but may be more volatile and subject to greater risk. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [GRAPHIC OF TRIANGLE] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 8.

It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS


The highest and lowest quarterly returns for the periods reflected in the bar
chart are:


                           HIGHEST                            LOWEST
--------------------------------------------------------------------------------
Heritage                   40.37% (4Q 1999)                   -21.16% (3Q 1998)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment. Because the B and R
Classes (which commenced operations September 28, 2007) do not have investment
results for a full calendar year, they are not included.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------
3


After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for the Investor Class shares. After-tax returns for the
other share classes will vary.

The benchmarks are unmanaged indices that have no operating costs and are
included in each table for performance comparison. The Russell Midcap Growth
Index measures the performance of those Russell Midcap Index companies (the 800
smallest of the 1,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values. The Russell Midcap Index measures the performance of the 800
smallest of the 1,000 largest publicly traded U.S. companies, based on total
market capitalization.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of medium-sized and smaller companies
they believe will increase in value over time, using an investment strategy
developed by American Century. In implementing this strategy, the portfolio
managers use a bottom-up approach to stock selection. This means that the
managers make their investment decisions based primarily on their analysis of
individual companies, rather than on broad economic forecasts. Management of the
fund is based on the belief that, over the long term, stock price movements
follow growth in earnings and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

The fund will usually purchase common stocks of companies that are medium-sized
and smaller at the time of purchase, but it can purchase other types of
securities as well. When determining the size of a company, the portfolio
managers will consider, among other factors, the capitalization of the company
and the amount of revenues as well as other information they obtain about the
company.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the portfolio
managers believe it is prudent, the fund may invest a portion of its assets in
debt securities, options, preferred stock and equity-equivalent securities, such
as convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of it's assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The fund generally invests in medium-sized and smaller companies, which may be
more volatile and subject to greater short-term risk. Smaller companies may have
limited financial resources, product lines and markets, and their securities may
trade less frequently and in more limited volumes than securities of larger
companies. In addition, smaller companies may have less publicly available
information.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

The fund's portfolio turnover may be high. This could result in relatively high
commission costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located in
foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These changes
may be magnified by the countries' emergent financial markets, resulting in
significant volatility to investments in these countries. These countries also
may lack the legal, business and social framework to support securities markets.

The fund's performance also may be affected by investments in initial public
offerings (IPOs). The impact of IPOs on the fund's performance depends on the
strength of the IPO market and the size of the fund. IPOs may have less impact
on the fund's performance as its assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

DAVID M. HOLLOND

Mr. Hollond, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since February 2007. He joined American Century in 1998
and became a portfolio manager in March 2004. He has a bachelor's degree in

SERVICES AUTOMATICALLY AVAILABLE TO YOU

Most accounts automatically will have access to the services listed under WAYS
TO MANAGE YOUR ACCOUNT when the account is opened. If you do not want these
services, see CONDUCTING BUSINESS IN WRITING. If you have questions about the
services that apply to your account type, please call us.

CONDUCTING BUSINESS IN WRITING

If you prefer to conduct business in writing only, you can indicate this on the
account application. If you choose this option, you must provide written
instructions to invest, exchange and redeem. All account owners must sign
transaction instructions (with signatures guaranteed for redemptions in excess
of $100,000). By choosing this option, you are not eligible to enroll for
exclusive online account management to waive the account maintenance fee. See
ACCOUNT MAINTENANCE FEE in this section. If you want to add online and telephone
services later, you can complete a Full Services Option form.

ACCOUNT MAINTENANCE FEE

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
we may charge you a $12.50 semiannual account maintenance fee if the value of
those shares is less than $10,000. We will determine the amount of your total
eligible investments twice per year, generally the last Friday in October and
April. If the value of those investments is less than $10,000 at that time, we
will automatically redeem shares in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In
determining your total eligible investment amount, we will include your
investments in all PERSONAL ACCOUNTS (including American Century Brokerage
accounts) registered under your Social Security number. We will not charge the
fee as long as you choose to manage your accounts exclusively online. You may
enroll for exclusive online account management on our Web site. To find out more

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

      [GRAPHIC OF TRIANGLE]

      FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS,
      INSURANCE COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                             AMOUNT PAID TO

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase, of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15


For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any American Century fund you intend to make over a 13-month
period to determine the applicable sales charge. At your request, existing
holdings may be combined with new purchases and sales charge amounts may be
adjusted for purchases made within 90 days prior to our receipt of the Letter of
Intent. Capital appreciation, capital gains and reinvested dividends earned
during the Letter of Intent period do not apply toward its completion. A portion
of your account will be held in escrow to cover additional A Class sales charges
that will be due if your total investments over the 13-month period do not
qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Shares purchased in accounts that held Advisor Class shares of this fund
   prior to September 4, 2007

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.


------
16




REDEMPTION DURING                         CDSC AS A % OF ORIGINAL PURCHASE PRICE
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
2nd year                                  4.00%
--------------------------------------------------------------------------------
3rd year                                  3.00%
--------------------------------------------------------------------------------
4th year                                  3.00%
--------------------------------------------------------------------------------
5th year                                  2.00%
--------------------------------------------------------------------------------
6th year                                  1.00%
--------------------------------------------------------------------------------
After 6th year                            None
--------------------------------------------------------------------------------


B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------
17


CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market
      value for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market
      value for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.


------
18


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.



------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

      [GRAPHIC OF TRIANGLE]




      A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.


------
21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption


------
22


fees on certain funds, and using fair value pricing when current market prices
are not readily available. Although these efforts are designed to discourage
abusive trading practices, they cannot eliminate the possibility that such
activity will occur. American Century seeks to exercise its judgment in
implementing these tools to the best of its ability in a manner that it believes
is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
24





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
25


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

      [GRAPHIC OF TRIANGLE]

      CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
      STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

      [GRAPHIC OF TRIANGLE]



      QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
      THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED
      THAT THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
28


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.


------
29


Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of smaller-sized companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * SMALL CAP STOCKS - The smaller companies in which the fund invests may present greater opportunities for capital appreciation than larger companies, but may also present greater risks. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * HIGH TURNOVER - The fund's PORFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [graphic of triangle] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7.

It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would have been lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                                 HIGHEST                      LOWEST

Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes. Returns assume the deduction of all sales loads,
charges and other fees associated with a particular class. Your actual returns
may vary depending on the circumstances of your investment. Because the
Institutional Class (which commenced operations May 18, 2007) and the R Class
(which commenced operations September 28, 2007) do not have investment results
for a full calendar year, they are not included.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for Investor Class shares. After-tax returns for other
share classes will vary.


The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell 2000(®) Growth Index
measures the performance of those Russell 2000 Index companies (the 2,000
smallest of the 3,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of smaller-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the managers make their
investment decisions based primarily on their analysis of individual companies,
rather than on broad economic forecasts. Management of the fund is based on the
belief that, over the long term, stock price movements follow growth in earnings
and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
a fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

When determining whether a company is smaller-sized, the portfolio managers will
consider, among other factors, the capitalization of the company and the amount
of revenues, as well as other information they obtain about the company. If the
companies in which the fund invests are successful, these companies may grow
into larger-sized companies. In addition, if the portfolio managers determine
that the availability of smaller-sized companies in which to invest is not
adequate to meet the fund's investment needs, the portfolio managers may invest
in medium- and large-sized companies.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's characteristics no longer meet
the fund's investment criteria. While the managers believe this strategy
provides substantial appreciation potential over the long term, in the short
term it can create a significant amount of share price volatility. This
volatility can be greater than that of the average stock fund.

Because the fund generally invests in smaller companies, it may be more
volatile, and subject to greater short-term risk, than funds that invest
primarily in larger companies. Smaller companies may have limited financial
resources, product lines and markets, and their securities may trade less
frequently and in more limited volumes than the securities of larger companies.
In addition, smaller companies may have less publicly available information.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located in
foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These changes
may be magnified by the countries' emergent financial markets, resulting in
significant volatility to investments in these countries. These countries also
may lack the legal, business and social framework to support securities markets.

The fund's turnover may be high. This could result in relatively high commission
costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

The fund's performance also may be affected by investments in initial public
offerings (IPOs). The impact of IPOs on the fund's performance depends on the
strength of the IPO market and the size of the fund. IPOs may have less impact
on the fund's performance as its assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for the fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

STAFFORD SOUTHWICK

Mr. Southwick, Vice President and Portfolio Manager, has been a member of the
team that manages the fund since joining American Century in June 2001 as an
investment analyst. He became a portfolio manager in April 2006. He has a
bachelor's degree in accounting from Southern Utah University and an MBA from
the University of Texas at Austin. He is a CFA charterholder.


MATTHEW FERRETTI

Mr. Ferretti, Portfolio Manager, rejoined the team that manages the fund in July
2006. He joined American Century in July 2002 as an investment analyst for the
fund. In May 2006, he became a senior investment analyst for the Select Fund. He
became a portfolio manager for the fund in July 2006. Prior to joining American
Century, Mr. Ferretti was a portfolio manager at Teacher Retirement System of
Texas. He has a bachelor of science from the University of Notre Dame, a JD from
Villanova University and an MBA from the University of Texas. He is a CFA
charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUND PERFORMANCE

New Opportunities and New Opportunities II have the same management team and
investment policies as one another. The fees and expenses of the funds are
expected to be similar, and they will be managed with substantially the same
investment objective and strategies. Notwithstanding these general similarities,
New Opportunities and New Opportunities II are separate mutual funds that will
have different investment performance. Differences in cash flows into and out of
the two funds, the level of assets under management in each portfolio and the
specific investments held by each of the two funds will cause performance to
differ.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objective of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

       [graphic of triangle]

       FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
       COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                               AMOUNT PAID

--------------------------------------------------------------------------------
$250,000 - $499,999        2.50%             2.56%             2.00%
--------------------------------------------------------------------------------
$500,000 - $999,999        2.00%             2.04%             1.75%

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
14


For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information.

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.



                                                         CDSC AS A % OF

B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).

CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market value
      for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market value
      for C Class shares

*  distributions from IRAs due to attainment of age 591/2 for A Class shares
   and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70 1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.

Some shares are subject to a redemption fee if they are exchanged in this manner
(see the SHAREHOLDER FEES table under FEES AND EXPENSES).


------
17


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of a fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

Broker-dealer sponsored wrap program accounts                         No minimum
and/or fee-based accounts
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)

Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but finan-cial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.



------
19


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

Some shares are subject to a redemption fee (see the SHAREHOLDER FEES table
under FEES AND EXPENSES). The redemption fee will be retained by the fund to
help cover transaction costs that long-term investors may bear when the fund
sells securities to meet investor redemptions.

The redemption fee does not apply to shares purchased through reinvested
distributions (dividends and capital gains). The fund may not charge the
redemption fee in certain situations deemed appropriate by American Century,
including where the capability to charge the fee does not exist or is
impractical and/or other systems to deter abusive trading practices are in
place.

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

       [graphic of triangle]




       A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.


------
20


We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Shares redeemed in this manner may be subject to a
redemption fee if held less than a specified number of days (see the SHAREHOLDER
FEES table under FEES AND EXPENSES). A, B and C Class shares redeemed in this
manner may be subject to a sales charge if held less than the applicable time
period. You also may incur tax liability as a result of the redemption. For
Institutional Class shares, we reserve the right to convert your shares to
Investor Class shares of the same fund. The Investor Class shares have a unified
management fee that is 0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.


------
21


ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

As a heightened measure for the fund, the board has approved the imposition of a
redemption fee for shares held less than a specified number of days. See the
SHAREHOLDER FEES table under FEES AND EXPENSES for a complete description of the
redemption fee applicable to the fund.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.


------
22



American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
23





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
24


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

       [graphic of triangle]

       CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
       STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
25


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of its investment securities. Distributions of income are taxed as
ordinary income, unless they are designated as QUALIFIED DIVIDEND INCOME and you
meet a minimum required holding period with respect to your shares of the fund,
in which case distributions of income are taxed as long-term capital gains.

       [graphic of triangle]



       QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE STOCK
       OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND
       HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                   TAX RATE FOR 10%          TAX RATE FOR
TYPE OF DISTRIBUTION               AND 15% BRACKETS          ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains           Ordinary Income           Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains
 ( 1 year) and Qualified
Dividend Income                    5%                        15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
26


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that the fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
27


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.


------
28


Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of smaller-sized companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * SMALL CAP STOCKS - The smaller companies in which the fund invests may present greater opportunities for capital appreciation than larger companies, but may also present greater risks. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [GRAPHIC OF TRIANGLE] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 6.

It indicates the volatility of the fund's historical returns from year to year. Account fees are not reflected in the chart below. If they had been included, returns would be lower than those shown.

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                                HIGHEST                        LOWEST

--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways.

Return Before Taxes shows the actual change in the value of fund shares over the
periods shown, but does not reflect the impact of taxes on fund distributions or
the sale of fund shares. The two after-tax returns take into account taxes that
may be associated with owning fund shares. Return After Taxes on Distributions
is a fund's actual performance, adjusted by the effect of taxes on distributions
made by the fund during the period shown. Return After Taxes on Distributions
and Sale of Fund Shares is further adjusted to reflect the tax impact on any
change in the value of fund shares as if they had been sold on the last day of
the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of smaller-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the managers make their
investment decisions based primarily on their analysis of individual companies,
rather than on broad economic forecasts. Management of the fund is based on the
belief that, over the long term, stock price movements follow growth in earnings
and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash equivalent securities or short-term debt securities. To the extent
a fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.


------

When determining whether a company is smaller-sized, the portfolio managers will
consider, among other factors, the capitalization of the company and the amount
of revenues, as well as other information they obtain about the company. If the
companies in which the fund invests are successful, these companies may grow
into larger-sized companies. In addition, if the portfolio managers determine
that the availability of small-sized companies in which to invest is not
adequate to meet the fund's investment needs, the portfolio managers may invest
in medium- and large-sized companies.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's characteristics no longer meet
the fund's investment criteria. While the managers believe this strategy
provides substantial appreciation potential over the long term, in the short
term it can create a significant amount of share price volatility. This
volatility can be greater than that of the average stock fund.

Because the fund generally invests in smaller companies, it may be more
volatile, and subject to greater short-term risk, than funds that invest
primarily in larger companies. Smaller companies may have limited financial
resources, product lines and markets, and their securities may trade less
frequently and in more limited volumes than the securities of larger companies.
In addition, smaller companies may have less publicly available information.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located in
foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These changes
may be magnified by the countries' emergent financial markets, resulting in
significant volatility to investments in these countries. These countries also
may lack the legal, business and social framework to support securities markets.

The fund's turnover may be high. This could result in relatively high commission
costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.



------
7


The fund's performance also may be affected by investments in initial public
offerings (IPOs). The impact of IPOs on the fund's performance depends on the
strength of the IPO market and the size of the fund. IPOs may have less impact
on the fund's performance as its assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for the fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

STAFFORD SOUTHWICK

Mr. Southwick, Vice President and Portfolio Manager, has been a member of the
team that manages the fund since joining American Century in June 2001 as an
investment analyst. He became a portfolio manager in April 2006. He has a
bachelor's degree in accounting from Southern Utah University and an MBA from
the University of Texas at Austin. He is a CFA charterholder.

MATTHEW FERRETTI

Mr. Ferretti, Portfolio Manager, rejoined the team that manages the fund in July
2006. He joined American Century in July 2002 as an investment analyst for the
fund. In May 2006, he became a senior investment analyst for the Select Fund. He
became a portfolio manager for the fund in July 2006. Prior to joining American
Century, Mr. Ferretti was a portfolio manager at Teacher Retirement System of
Texas. He has a bachelor of science from the University of Notre Dame, a JD from
Villanova University and an MBA from the University of Texas. He is a CFA
charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.





FUND PERFORMANCE

New Opportunities and New Opportunities II have the same management team and
investment policies as one another. The fees and expenses of the funds are
expected to be similar, and they will be managed with substantially the same
investment objective and strategies. Notwithstanding these general similarities,
New Opportunities and New Opportunities II are separate mutual funds that will
have different investment performance. Differences in cash flows into and out of
the two funds, the level of assets under management in each portfolio and the
specific investments held by each of the two funds will cause performance to
differ.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objective of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

ACCOUNT MAINTENANCE FEE

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
we may charge you a $12.50 semiannual account maintenance fee if the value of
those shares is less than $10,000. We will determine the amount of your total
eligible investments twice per year, generally the last Friday in October and
April. If the value of those investments is less than $10,000 at that time, we
will automatically redeem shares in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In
determining your total eligible investment amount, we will include your
investments in all PERSONAL ACCOUNTS (including American Century Brokerage
accounts) registered under your Social Security number. We will not charge the
fee as long as you choose to manage your accounts exclusively online. You may
enroll for exclusive online account management on our Web site. To find out more
about exclusive online account management, visit americancentury.com/info/demo.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

If you do business with us through a financial intermediary or an
employer-sponsored retirement plan, your ability to purchase, exchange, redeem
and transfer shares will be affected by the policies of that entity. For more
information regarding employer-sponsored retirement plan types, please see
BUYING AND SELLING FUND SHARES in the statement of additional information.

Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

Please contact your FINANCIAL INTERMEDIARY or plan sponsor for a complete
description of its policies. Copies of the fund's annual report, semiannual
report and statement of additional information are available from your financial
intermediary or plan sponsor.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
   COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.



------
13


Although fund share transactions may be made directly with American Century at
no charge, you also may purchase, redeem and exchange fund shares through
financial intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the financial intermediary and are not
shared with American Century or the fund.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT



MINIMUM INITIAL INVESTMENT AMOUNTS

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------

--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

REDEMPTIONS

The shares are subject to a redemption fee (see the SHAREHOLDER FEES table under
FEES AND EXPENSES). The redemption fee will be retained by the fund to help
cover transaction costs that long-term investors may bear when the fund sells
securities to meet investor redemptions.

The redemption fee does not apply to shares purchased through reinvested
distributions (dividends and capital gains). The fund may not charge the
redemption fee in certain situations deemed appropriate by American Century,
including where the capability to charge the fee does not exist or is
impractical and/or other systems to deter abusive trading practices are in
place.

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.


------
15


SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Shares redeemed in this manner may be subject to a
redemption fee if held less than a specified number of days (see the SHAREHOLDER
FEES table under FEES AND EXPENSES). You also may incur tax liability as a
result of the redemption.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.


------
16


ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

As a heightened measure for the fund, the board has approved the imposition of a
redemption fee for shares held less than a specified number of days. See the
SHAREHOLDER FEES table under FEES AND EXPENSES for a complete description of the
redemption fee applicable to the fund.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.


------
17



American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
18





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs
   that may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
19


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
   STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
20


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
21


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or a financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that the fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth and current income by investing approximately 60% of its assets in equity securities and the remainder in bonds and other fixed-income securities.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGY AND PRINCIPAL RISKS? For the equity portion of Balanced, the portfolio managers select stocks primarily from the largest 1,500 publicly traded U.S. companies. For the fixed-income portion of the fund, the portfolio managers invest in a diversified portfolio of high- and medium-grade securities. The fund's principal risks include * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * INTEREST RATE RISK - When interest rates change, the value of the fund's fixed-income securities will be affected. * CREDIT RISK - The value of the fund's debt securities will be affected adversely by any erosion in the ability of the issuers of these securities to make interest and principal payments as they become due. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategy and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 6. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each of the last 10 calendar years. It indicates the volatility of the fund's historical returns from year to year. Account fees are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                            HIGHEST                            LOWEST

Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for Investor Class shares. After-tax returns for the
other classes will vary.

The benchmarks are unmanaged indices that have no operating costs and are
included in each table for performance comparison. The blended index is
considered the benchmark for Balanced. It combines two widely known indices in
proportion to the asset mix of the fund. Accordingly, 60% of the index is
represented by the S&P 500 Index, which reflects the approximately 60% of the
fund's assets invested in stocks. The blended index's remaining 40% is
represented by the Citigroup US Broad Investment-Grade Bond Index, which
reflects the roughly 40% of the fund's assets invested in fixed-income
securities. The S&P 500 Index is a market value-weighted index of the stocks of
500 publicly traded U.S. companies chosen for market size, liquidity, and
industry group representation that are considered to be leading firms in
dominant industries. The Citigroup US Broad Investment-Grade (BIG) Bond Index is
a market-capitalization-weighted index that includes fixed-rate Treasury,
government-sponsored, mortgage, asset-backed, and investment-grade issues with a
maturity of one year or longer.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

This fund seeks long-term capital growth and current income by investing
approximately 60% of its assets in equity securities and the remainder in bonds
and other fixed-income securities.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

For the equity portion of the fund's portfolio, the portfolio managers utilize
quantitative management techniques in a two-step process that draws heavily on
computer technology. In the first step, the portfolio managers rank stocks,
primarily the 1,500 largest publicly traded companies in the United States
(measured by the value of their stock), from most attractive to least
attractive. These rankings are determined by using a computer model that
combines measures of a stock's value, as well as measures of its growth
potential. To measure value, the managers use ratios of stock price-to-book
value and stock price-to-cash flow, among others. To measure growth, the
managers use the rate of growth of a company's earnings and changes in its
earnings estimates, as well as other factors.

In the second step, the managers use a technique called portfolio optimization.
In portfolio optimization, the managers use a computer to build a portfolio of
stocks from the ranking described above that they believe will provide the
optimal balance between risk and expected return. The goal is to create an
equity portfolio that provides better returns than the S&P 500 without taking on
significant additional risk.

The portfolio managers also consult the rankings described above when
determining whether to sell a particular security. As a security's ranking
falls, the portfolio managers will consider many factors in addition to the
computer-generated information for the security, including, among other things,
a security's price, whether a security's risk parameters outweigh its return
opportunities, general market conditions, and any other factors deemed relevant
by the portfolio manager.

The fixed-income portion of the fund's portfolio is invested primarily in a
diversified portfolio of high- and medium-grade government, corporate,
asset-backed and similar securities payable in U.S. or foreign currencies. At
least 80% of the fixed-income assets will be invested in securities that are
rated within the four highest categories by a nationally recognized statistical
rating organization. Up to 15% may be invested in securities rated in the fifth
category. The rating category of a security will be determined at the time of
purchase. In the event a security is subsequently downgraded, the fund will not
be obligated to dispose of that security, but may continue to hold the security
if deemed appropriate by the portfolio managers. Under normal market conditions,
the WEIGHTED AVERAGE MATURITY for the fixed-income portfolio will be in the
three- to 10-year range.


      [GRAPHIC OF TRIANGLE]

      WEIGHTED AVERAGE MATURITY IS A TOOL THE PORTFOLIO MANAGERS USE TO
      APPROXIMATE THE REMAINING TERM TO MATURITY OF A FUND'S INVESTMENT
      PORTFOLIO. GENERALLY, THE LONGER A FUND'S WEIGHTED AVERAGE MATURITY,
      THE MORE SENSITIVE IT IS TO CHANGES IN INTEREST RATES.


------

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the equity portion of the fund
essentially fully invested in stocks regardless of the movement of stock prices
generally. When the portfolio managers believe it is prudent, the fund may
invest a portion of its assets in foreign securities, short-term securities,
preferred stock and equity-equivalent securities, such as convertible securities
and nonleveraged futures contracts. The fund may purchase mortgage-backed
securities, on a when-issued or forward commitment basis. These transactions may
be executed using dollar rolls or other investment techniques. Futures
contracts, a type of derivative security, can help the fund's cash assets remain
liquid while performing more like stocks. The fund has a policy governing
futures contracts and similar derivative securities to help manage the risk of
these types of investments. A complete description of the derivatives policy is
included in the statement of additional information.

The fund may invest in securities issued or guaranteed by the U.S. Treasury and
certain U.S. government agencies or instrumentalities such as the Government
National Mortgage Association (Ginnie Mae). Ginnie Mae is supported by the full
faith and credit of the U.S. government. Securities issued or guaranteed by
other U.S. government agencies or instrumentalities, such as the Federal
National Mortgage Association (Fannie Mae), the Federal Home Loan Mortgage
Corporation (Freddie Mac), and the Federal Home Loan Bank (FHLB) are not
guaranteed by the U.S. Treasury or supported by the full faith and credit of the
U.S. government. However, they are authorized to borrow from the U.S. Treasury
to meet their obligations.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

The value of the fund's shares depends on the value of the stocks, bonds and
other securities it owns.

*  The value of the individual equity securities the fund owns will go up and
   down depending on the performance of the companies that issued them, general
   market and economic conditions, and investor confidence.

*  The value of the fund's fixed-income securities will be affected primarily
   by rising or falling interest rates and the continued ability of the issuers
   of these securities to make payments of interest and principal as they become
   due.

Generally, when interest rates rise, the value of the fund's fixed-income
securities will decline. The opposite is true when interest rates decline. The
interest rate risk is higher for the fixed-income portion of the fund than for
funds that have a shorter-weighted average maturity, such as money market and
short-term bond funds.


------

The lower-rated bonds in which the fund may invest, BBB- and BB rated bonds,
contain some speculative characteristics. As a result, the fund has some credit
risk. Although their securities are considered investment-grade, issuers of
BBB-rated securities (and securities of similar quality) are more likely to have
problems making interest and principal payments than issuers of higher rated
securities. Issuers of BB-rated securities (and securities of similar quality)
are considered even more vulnerable to adverse business, financial or economic
conditions that could lead to difficulties in making timely payments of
principal and interest. Having these bonds in the fund's portfolio means the
fund's value may go down more if interest rates or other economic conditions
change than if the fund contained only higher-rated bonds.


      [GRAPHIC OF TRIANGLE]

      FIXED-INCOME SECURITIES ARE RATED BY NATIONALLY RECOGNIZED SECURITIES
      RATING ORGANIZATIONS (SROS), SUCH AS MOODY'S AND STANDARD & POOR'S.
      EACH SRO HAS ITS OWN SYSTEM FOR CLASSIFYING SECURITIES, BUT EACH TRIES
      TO INDICATE A COMPANY'S ABILITY TO MAKE TIMELY PAYMENTS OF INTEREST AND
      PRINCIPAL. A DETAILED DESCRIPTION OF SROS, THEIR RATINGS SYSTEMS AND
      WHAT WE DO IF A SECURITY ISN'T RATED IS INCLUDED IN THE STATEMENT OF
      ADDITIONAL INFORMATION.


The fund may invest in debt securities backed by mortgages or assets such as
auto loan, home equity loan or student loan receivables. These underlying
obligations may be prepaid, as when a homeowner refinances a mortgage to take
advantage of declining interest rates. If so, the fund must reinvest prepayments
at current rates, which may be less than the rate of the prepaid mortgage.
Because of this prepayment risk, the fund may benefit less from declining
interest rates than funds of similar maturity that invest less heavily in
mortgage- and asset-backed securities.

The use of derivative instruments involves risks different from, or possibly
greater than, the risks associated with investing directly in securities and
other traditional instruments. Derivatives are subject to a number of risks,
including liquidity, interest rate, market, and credit risk. They also involve
the risk of mispricing or improper valuation, the risk that changes in the value
of the derivative may not correlate perfectly with the underlying asset, rate or
index, and the risk of default or bankruptcy of the other party to the swap
agreement. Gains or losses involving some futures, options, and other
derivatives may be substantial - in part because a relatively small price
movement in these securities may result in an immediate and substantial gain or
loss for the fund.

Because the equity portion of the fund uses quantitative management techniques
to try to achieve a total return that exceeds the total return of the S&P 500®
Index, its performance will correlate to the index's performance. If the index
goes down, it is likely that the fund's performance will go down.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, it is possible that the fund's
strategy assets will not include assets of other client accounts or that any
such assets may not be sufficient to result in a lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

will automatically redeem shares in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In

INVESTING THROUGH A FINANCIAL INTERMEDIARY

If you do business with us through a financial intermediary or a retirement
plan, your ability to purchase, exchange, redeem and transfer shares will be
affected by the policies of that entity.

Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

Please contact your FINANCIAL INTERMEDIARY or plan sponsor for a complete
description of its policies. Copies of the fund's annual report, semiannual
report and statement of additional information are available from your financial
intermediary or plan sponsor. For more information regarding employer-sponsored
retirement plan types, please see BUYING AND SELLING FUND SHARES in the
statement of additional information.

      [GRAPHIC OF TRIANGLE]

      FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
      COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund, and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.



------
15



Although fund share transactions may be made directly with American Century at
no charge, you also may purchase, redeem and exchange fund shares through
financial intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the financial intermediary and are not
shared with American Century or the fund.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program accounts
and/or fee-based accounts                                          No minimum

Employer-sponsored retirement plans                                No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

      [GRAPHIC OF TRIANGLE]




      A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.


------
17


However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that you may incur tax liability as a
result of the redemption. For Institutional Class shares, we reserve the right
to convert your shares to Investor Class shares of the same fund. The Investor
Class shares have a unified management fee that is 0.20% higher than the
Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.


------
18


*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. Each fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.


------
19


To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
21


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities.

      [GRAPHIC OF TRIANGLE]

      CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
      STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

The fund pays distributions from net income quarterly and generally pays
distributions from realized capital gains, if any, once a year in December. The
fund may make more frequent distributions, if necessary, to comply with Internal
Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
22


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

      [GRAPHIC OF TRIANGLE]



      QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE STOCK
      OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND
      HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
23


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class and Institutional Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences between the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting that class; (d) each class may
have different exchange privileges; and (e) the Institutional Class may provide
for automatic conversion from that class into shares of the Investor Class of
the same fund.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio manager looks for stocks of companies he believes will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio manager makes his investment decisions based primarily on his analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio manager uses an approach to common stock investing designed to identify companies, regardless of size, industry type or geographic location, that are growing at an accelerating rate and whose share price patterns suggest their stocks are likely to increase in value. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * INVESTMENT PROCESS - There is also risk associated with reliance on the fund's computer-based investment process. If the investment style embedded in this process falls out of favor with the market, the fund's performance may suffer. * NONDIVERSIFICATION - The fund is classified as NONDIVERSIFIED. This gives the portfolio manager the flexibility to hold large positions in a small number of securities. If so, a price change in any one of those securities may have a greater impact on the fund's share prices than would be the case in a diversified fund. [graphic of triangle] A NONDIVERSIFIED FUND MAY INVEST A GREATER PERCENTAGE OF ITS ASSETS IN A SMALLER NUMBER OF SECURITIES THAN A DIVERSIFIED FUND. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [graphic of triangle] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. ------ 2 * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7. [graphic of triangle] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 3 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each full calendar year in the life of the class. It indicates the volatility of the fund's historical returns from year to year. Account fees are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other class of shares will differ from those shown in the chart, depending on the expenses of that class. INVESTOR CLASS

Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. An additional table shows
the average annual total returns of the fund's other share class calculated
before the impact of taxes.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for the Investor Class shares. After-tax returns for the
other share class will vary.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund uses an approach to common stock investing developed by American
Century. This approach relies heavily on quantitative tools to identify
attractive investment opportunities, regardless of company size, industry type
or geographic location, on a disciplined, consistent basis.

These tools include a fundamental process that screens thousands of publicly
traded securities to identify those that meet the fund's proprietary
accelerating growth requirements.

The fund's methodology also attempts to identify companies whose share price
patterns suggest increasing or decreasing investor demand (commonly referred to
as technical analysis). This technical analysis is particularly oriented to
identifying attractive price patterns for companies whose earnings and revenues
are not only growing, but growing at an accelerating pace. This includes
companies whose growth rates, although still negative, are less negative than
prior periods, and companies whose growth rates are expected to accelerate.
These companies would be candidates for purchase. Conversely, companies whose
share price patterns suggest a likely decline in price would be candidates for
sale, if owned by the fund. On occasion, the process may look favorably on a
company whose share price pattern appears attractive even though the company
looks less attractive based on the growth screen.

Although the portfolio manager intends to invest the fund's assets in U.S.
companies, the fund may invest in securities of foreign companies, including
companies located in emerging markets. The fund will usually purchase common
stocks, but it can purchase other types of securities as well, such as U.S.
Government and other debt securities, preferred stock and equity-equivalent
securities, such as convertible securities, stock futures contracts or stock
index futures contracts. The fund generally limits its purchase of debt
securities to investment-grade obligations.

The portfolio manager does not attempt to time the market. Instead, he intends
to keep the fund essentially fully invested in stocks that meet the fund's
selection criteria. However, at the portfolio manager's discretion, the fund may
invest up to 100% of its assets in U.S. government securities if the fund's
investment methodology fails to generate sufficient investment ideas or to
respond to adverse market, economic, political or other conditions. The fund may
not achieve its investment objectives while taking such a temporary defensive
position.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.


------
7


The portfolio manager may buy a large amount of a company's stock quickly and
often will dispose of it quickly if it no longer meets his investment criteria.
While the portfolio manager believes this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

The fund is classified as nondiversified. This means that the fund's portfolio
manager may choose to invest in a relatively small number of securities. If so,
a price change in any one of these securities may have a greater impact on the
fund's share price than would be the case if the fund were diversified. Although
the fund's portfolio manager expects it will ordinarily satisfy the requirements
for a diversified fund, its nondiversified status gives him more flexibility to
invest heavily in the most attractive companies identified by the fund's
methodology.

The process driving the fund is specifically designed to respond quickly to
changing stock market conditions. As a result, the fund's portfolio turnover may
be significantly higher than that of many other funds. This heavy turnover,
perhaps as much as 200-400% per year or more, could result in relatively high
commission costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

Although the portfolio manager intends to invest the fund's assets in U.S.
stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of the fund could be affected.

Investing in securities of companies located in emerging market countries
generally is also riskier than investing in securities of companies located in
foreign developed countries. Emerging market countries may have unstable
governments and/or economies that are subject to sudden change. These changes
may be magnified by the countries' emergent financial markets, resulting in
significant volatility to investments in these countries. These countries also
may lack the legal, business and social framework to support securities markets.

Market performance tends to be cyclical, and in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the style embedded in the fund's investment process, the fund's gains may not be
as big as, or its losses may be bigger than, other equity funds using different
investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities a fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for the fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio manager on the investment team who is primarily responsible for
the day-to-day management of the fund is:

JOHN T. SMALL JR.

Mr. Small, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since its inception in November 1999. He joined American
Century in May 1991 and became a portfolio manager in February 1999. He has a
bachelor's degree in zoology from Rockford College, a master's degree in laser
optics physics from the Air Force Institute of Technology, and an MBA from Baker
University.

The statement of additional information provides additional information about
the accounts managed by the portfolio manager, the structure of his
compensation, and his ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

If you do business with us through a financial intermediary or a retirement
plan, your ability to purchase, exchange, redeem and transfer shares will be
affected by the policies of that entity. For more information regarding
employer-sponsored retirement plan types, please see BUYING AND SELLING FUND
SHARES in the statement of additional information.

Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

Please contact your FINANCIAL INTERMEDIARY or plan sponsor for a complete
description of its policies. Copies of the fund's annual report, semiannual
report and statement of additional information are available from your financial
intermediary or plan sponsor.

     [graphic of triangle]

     FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
     COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

Although fund share transactions may be made directly with American Century at
no charge, you also may purchase, redeem and exchange fund shares through
financial intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the financial intermediary and are not
shared with American Century or the fund.


------
13


The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on a fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

The shares are subject to a redemption fee (see the SHAREHOLDER FEES table under
FEES AND EXPENSES). The redemption fee will be retained by the fund to help
cover transaction costs that long-term investors may bear when the fund sells
securities to meet investor redemptions.



------
15


The redemption fee does not apply to shares purchased through reinvested
distributions (dividends and capital gains). The fund may not charge the
redemption fee in certain situations deemed appropriate by American Century,
including where the capability to charge the fee does not exist or is
impractical and/or other systems to deter abusive trading practices are in
place.

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

     [graphic of triangle]




     A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
manager would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Shares redeemed in this manner may be subject to a
redemption fee if held less than a specified number of days (see the SHAREHOLDER
FEES table under FEES AND EXPENSES). You also may incur tax liability as a
result of the redemption. For Institutional Class shares, we reserve the right
to convert your shares to Investor Class shares of the same fund. The Investor
Class shares have a unified management fee that is 0.20% higher than the
Institutional Class.



------
16


SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of the fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.


------
17


American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

As a heightened measure for the fund, the board has approved the imposition of a
redemption fee for shares held less than a specified number of days. See the
SHAREHOLDER FEES table under FEES AND EXPENSES for a complete description of the
redemption fee applicable to the fund.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.


------
19





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
20


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

     [graphic of triangle]

     CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS STOCK,
     FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
21


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by the fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

     [graphic of triangle]



     QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM THE STOCK
     OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND HAS
     HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
22


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
23


MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class and Institutional Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences between the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; and (e) the Institutional Class may provide
for automatic conversion from that class into shares of the Investor Class of
the same fund.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers use a value investment strategy that invests primarily in stocks of medium to large companies that the portfolio managers believe are undervalued at the time of purchase. In selecting stocks, the portfolio managers look for companies that are temporarily out of favor in, or whose value is not yet recognized by, the market. The portfolio managers also attempt to minimize taxable distributions to fund shareholders. The fund's principal risks include * VALUE INVESTING - If the market does not consider the individual stocks purchased by the fund to be undervalued, the value of the fund's shares may decline, even if stock prices generally are rising. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 7. [graphic of triangle] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's Investor Class shares for each full calendar year in the life of the class. It indicates the volatility of the fund's historical returns from year to year. Account fees are not reflected in the chart below. If they had been included, returns would be lower than those shown. The returns of the fund's other classes will differ from those shown in the chart, depending on the expenses of those classes. INVESTOR CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                              HIGHEST                          LOWEST
--------------------------------------------------------------------------------
Capital Value                 17.67% (2Q 2003)                 -17.95% (3Q 2002)
--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Investor Class shares calculated three different ways. Additional tables show
the average annual total returns of the fund's other share classes calculated
before the impact of taxes.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for Investor Class shares. After-tax returns for other
share classes will vary.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers seek to achieve the fund's objective by investing
primarily in common stocks. The portfolio managers also will attempt to minimize
the impact of federal income taxes on shareholder returns by attempting to
minimize taxable distributions to shareholders.

The portfolio managers use a value investment strategy to look for stocks of
medium to large companies the portfolio managers believe are undervalued at the
time of purchase. The portfolio managers attempt to purchase the stocks of these
undervalued companies and hold them until they have returned to favor in the
market and their stock prices have gone up.

Companies may be undervalued due to market declines, poor economic conditions,
actual or anticipated bad news regarding the issuer or its industry, or because
they have been overlooked by other investors. To identify these companies, the
portfolio managers look for companies with earnings, cash flows and/or assets
that may not be reflected accurately in the companies' stock prices.

To minimize taxable distributions, the portfolio managers employ the following
tax-sensitive techniques that may, from time to time, be inconsistent with the
fund's objective of long-term capital growth:

*  The portfolio managers seek to minimize realized capital gains by keeping
   portfolio turnover relatively low and generally holding portfolio investments
   for longer periods.

*  The portfolio managers seek to minimize realized capital gains when
   selling the shares of a specific company by analyzing the fund's holdings of
   that company to determine which shares were purchased at what price and
   typically selling those shares bought at the highest price.

*  The portfolio managers may seek to minimize realized capital gains by
   selling securities to realize capital losses. Realized capital losses can
   offset realized capital gains, thereby reducing capital gains distributions
   to the fund's shareholders.

*  The portfolio managers may seek to minimize taxable dividend income where
   appropriate by investing in stocks with lower dividend yields.

While the fund seeks to minimize taxable distributions to shareholders, it may
realize taxable gains and earn some dividends. For example, the portfolio
managers may elect to sell a security, even if the sale results in a taxable
gain, if they determine that the tax impact of the sale is outweighed by other
factors. Such factors include the investment risk of holding the security or the
availability of a replacement security that has a better potential return.
Because the fund is managed to provide high after-tax returns, it may not
provide as high a pre-tax return as other funds. For more information regarding
applicable taxes, see TAXES, page 20.


------

Although the portfolio managers intend to invest the fund's assets primarily in
U. S. stocks, the fund may invest in securities of foreign companies. The fund
will usually purchase common stocks, but it can purchase other types of
securities as well, such as debt securities, preferred stock and
equity-equivalent securities, such as convertible securities, stock futures
contracts or stock index futures. The fund generally limits its purchase of debt
securities to investment-grade obligations, except for convertible securities,
which may be rated below investment grade.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a temporary defensive position it will not be pursuing its
objective of long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

If the market does not consider the individual stocks purchased by the fund to
be undervalued, the value of the fund's shares may not rise as high as other
funds and may in fact decline, even if stock prices generally are increasing.

While the fund seeks to minimize taxable distributions to shareholders, it
nonetheless may realize capital gains on the sale of investment securities and
earn dividend income. For example, the portfolio managers may elect to sell a
security even if it results in a taxable gain if the managers determine the tax
impact of the sale is outweighed by other factors (such as the investment risk
of the security). Federal tax laws require the fund to make distributions of
such gains and income to its shareholders on at least an annual basis.
Distributions may be taxable as ordinary income, capital gains, or a combination
of the two.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. To the
extent the fund invests in foreign securities, the overall risk of the fund
could be affected. Foreign investment involves additional risks, including
fluctuations in currency exchange rates, less stable political and economic
structures, reduced availability of public information, and lack of uniform
financial reporting and regulatory practices similar to those that apply in the
United States. These factors make investing in foreign securities generally
riskier than investing in U.S. stocks.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale

INVESTING DIRECTLY WITH AMERICAN CENTURY

SERVICES AUTOMATICALLY AVAILABLE TO YOU

Most accounts automatically will have access to the services listed under WAYS
TO MANAGE YOUR ACCOUNT when the account is opened. If you do not want these
services, see CONDUCTING BUSINESS IN WRITING. If you have questions about the
services that apply to your account type, please call us.

CONDUCTING BUSINESS IN WRITING

If you prefer to conduct business in writing only, you can indicate this on the
account application. If you choose this option, you must provide written
instructions to invest, exchange and redeem. All account owners must sign
transaction instructions (with signatures guaranteed for redemptions in excess
of $100,000). By choosing this option, you are not eligible to enroll for
exclusive online account management to waive the account maintenance fee. See
ACCOUNT MAINTENANCE FEE in this section. If you want to add online and telephone
services later, you can complete a Full Services Option form.


ACCOUNT MAINTENANCE FEE

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
we may charge you a $12.50 semiannual account maintenance fee if the value of
those shares is less than $10,000. We will determine the amount of your total
eligible investments twice per year, generally the last Friday in October and
April. If the value of those investments is less than $10,000 at that time, we
will automatically redeem shares in one of your accounts to pay the $12.50 fee.
Please note that you may incur tax liability as a result of the redemption. In
determining your total eligible investment amount, we will include your
investments in all PERSONAL ACCOUNTS (including American Century Brokerage
accounts) registered under your Social Security number. We will not charge the
fee as long as you choose to manage your accounts exclusively online. You may
enroll for exclusive online account management on our Web site. To find out more

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's Advisor Class is intended for purchase by participants in
employer-sponsored retirement plans and for persons purchasing shares through
FINANCIAL INTERMEDIARIES that provide various administrative and distribution
services. For more information regarding employer-sponsored retirement plan
types, please see BUYING AND SELLING FUND SHARES in the statement of additional
information.

     [graphic of triangle]

     FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
     COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

INVESTING WITH US.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

Broker-dealer sponsored wrap program accounts
and/or fee-based accounts                                             No minimum
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)
--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.

MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

     [graphic of triangle]




     A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.


------
14


However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on a fund and its remaining investors.

REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that you may incur tax liability as a
result of the redemption. For Institutional Class shares, we reserve the right
to convert your shares to Investor Class shares of the same fund. The Investor
Class shares have a unified management fee that is 0.20% higher than the
Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.


------
15


*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of a fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.


------
16


To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

17





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
18


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities.

     [graphic of triangle]

     CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS
     STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

The fund generally pays distributions from net income and capital gains, if any,
once a year in December. The fund may make more frequent distributions, if
necessary, to comply with Internal Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
19


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Although the fund seeks to maximize long-term capital growth while minimizing
taxable distributions, the fund nonetheless may make distributions to its
shareholders. For example, the fund's portfolio managers may elect to sell a
security even if it results in a taxable gain if they determine the tax impact
is outweighed by the investment risk of the security or by the availability of
replacement securities that are a better value after considering the tax effect
of the sale.

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by the fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

     [graphic of triangle]



     QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE STOCK
     OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE FUND
     HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is


------
20


generally not subject to tax, but will reduce your cost basis in the fund and
result in higher realized capital gains (or lower realized capital losses) upon
the sale of fund shares.

The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

MULTIPLE CLASS INFORMATION

American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class and Advisor Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; and (e) the Institutional Class may provide
for automatic conversion from that class into shares of the Investor Class of
the same fund.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. The Advisor Class offered by this prospectus has a 12b-1 Plan.
Under the Advisor Class Plan, the fund's Advisor Class pays the distributor an
annual fee of 0.25% of Advisor Class average net assets, for distribution and
individual shareholder services, including past distribution services. The
distributor pays all or a portion of such fees to financial intermediaries that
make Advisor Class shares available. Because these fees may be used to pay for
services that are not related to prospective sales of the fund, the Advisor
Class will continue to make payments under its plan even if it is closed to new
investors. Because these fees are paid out of the fund's assets on an ongoing
basis, over time these fees will increase the cost of your investment and may
cost you more than paying other types of sales charges. For additional
information about the plan and its terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers look for stocks of companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings, revenues and/or cash flow. The portfolio managers use a variety of analytical research tools and techniques to identify the stocks of larger-sized companies that meet their investment criteria. Under normal market conditions, the fund's portfolio will primarily consist of securities of companies demonstrating business improvement. The fund is not permitted to invest in securities issued by companies assigned the Global Industry Classification Standard (GICS) for the tobacco industry. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * TOBACCO EXCLUSION - The fund's prohibition on tobacco-related investments may cause it to forego profitable investment opportunities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 6.

Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Institutional Class shares calculated three different ways.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs.

The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell 1000 Growth Index measures
the performance of those Russell 1000 Index companies (the 1,000 largest of the
3,000 largest publicly traded U.S. companies, based on total market
capitalization) with higher price-to-book ratios and higher forecasted growth
rates.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers look for stocks of larger-sized companies they believe
will increase in value over time, using an investment strategy developed by
American Century. In implementing this strategy, the portfolio managers use a
bottom-up approach to stock selection. This means that the portfolio managers
make their investment decisions based primarily on their analysis of individual
companies, rather than on broad economic forecasts. Management of the fund is
based on the belief that, over the long term, stock price movements follow
growth in earnings, revenues and/or cash flow.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for individual companies to identify and evaluate trends in earnings, revenues
and other business fundamentals. Under normal market conditions, the fund's
portfolio will primarily consist of securities of companies demonstrating
business improvement. Analytical indicators helping to identify signs of
business improvement could include accelerating earnings or revenue growth
rates, increasing cash flows, or other indications of the relative strength of a
company's business. These techniques help the portfolio managers buy or hold the
stocks of companies they believe have favorable growth prospects and sell the
stocks of companies whose characteristics no longer meet their criteria.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the managers
believe it is prudent, the fund may invest a portion of its assets in debt
securities, options, preferred stock and equity-equivalent securities, such as
convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

The fund is not permitted to invest in securities issued by companies assigned
the Global Industry Classification Standard (GICS) for the tobacco industry. If
the issuer of a security purchased by the fund is subsequently found to be
classified in the tobacco industry (due to acquisition, merger or otherwise),
the fund will sell the security as soon as reasonably possible.


------
6


In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The fund is not permitted to invest in certain tobacco-related securities. As a
result, the fund may forego a profitable investment opportunity or sell a
security when it may be disadvantageous to do so.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund and the Growth
fund as well as certain assets of other clients of the advisor outside the
American Century fund family (such as subadvised funds and separate accounts)
that use very similar investment teams and strategies. The use of strategy
assets, rather than fund assets, in calculating the fund's fee rate could allow
the fund to realize scheduled cost savings more quickly. However, it is possible
that the fund's strategy assets will not include assets of other client accounts
or that any such assets may not be sufficient to result in a lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers and analysts to manage funds. The
teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

GREGORY J. WOODHAMS

Mr. Woodhams, Vice President and Senior Portfolio Manager, has been a member of
the team that manages the fund since the fund's inception. He joined American
Century in September 1997 and became a portfolio manager in May 1998. He has a
bachelor's degree in economics from Rice University and an M.A. in economics
from the University of Wisconsin. He is a CFA charterholder.

E. A. PRESCOTT LEGARD

Mr. LeGard, Vice President and Portfolio Manager, has been a member of the team
that manages the fund since the fund's inception. He joined American Century in
March 1999 and became a portfolio manager in April 2000. He has a bachelor's
degree in economics from DePauw University. He is a CFA charterholder.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.





FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING WITH AMERICAN CENTURY

PURCHASE OF FUND SHARES

The fund is available for purchase only by certain funds of funds advised by
American Century. Transactions involving fund shares are effected using systems
and procedures internal to American Century.

REDEMPTIONS

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. In addition, we reserve the right to honor certain redemptions with
securities, rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.


------
10


American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.

Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.


------
12


Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities. The fund generally pays
distributions from net income and capital gains, if any, once a year in
December. The fund may make more frequent distributions, if necessary, to comply
with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
13


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
14


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions-including exchanges to other American Century funds-are subject
to capital gains tax. The table above can provide a general guide for your
potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. An Overview of the Fund WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The portfolio managers primarily look for stocks of medium-sized and smaller companies they believe will increase in value over time, using an investment strategy developed by American Century. In implementing this strategy, the portfolio managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts. Management of the fund is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues. The portfolio managers' principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. The fund is not permitted to invest in securities issued by companies assigned the Global Industry Classification Standard (GICS) for the tobacco industry. The fund's principal risks include * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * MID CAP STOCKS - The fund invests in mid-sized and smaller companies which may present greater opportunities for capital growth than larger companies, but may be more volatile and subject to greater risk. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * TOBACCO EXCLUSION - The fund's prohibition on tobacco-related investments may cause it to forego profitable investment opportunities. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * HIGH TURNOVER - The fund's PORTFOLIO TURNOVER may be high. This could result in relatively high commission costs, which could hurt the fund's performance, and capital gains tax liabilities for the fund's shareholders. [GRAPHIC OF TRIANGLE] PORTFOLIO TURNOVER IS A MEASURE OF HOW FREQUENTLY A FUND BUYS AND SELLS PORTFOLIO SECURITIES. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 6.

It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would be lower than those shown. INSTITUTIONAL CLASS

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

                            HIGHEST                             LOWEST

--------------------------------------------------------------------------------


Average Annual Total Returns

The following table shows the average annual total returns of the fund's
Institutional Class shares calculated three different ways.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs.

The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell Midcap Growth® Index
measures the performance of those Russell Midcap Index companies (the 800
smallest of the 1,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The portfolio managers primarily look for stocks of medium-sized and smaller
companies they believe will increase in value over time, using an investment
strategy developed by American Century. In implementing this strategy, the
portfolio managers use a bottom-up approach to stock selection. This means that
the managers make their investment decisions based primarily on their analysis
of individual companies, rather than on broad economic forecasts. Management of
the fund is based on the belief that, over the long term, stock price movements
follow growth in earnings and revenues.

Using American Century's extensive computer database, as well as other primary
analytical research tools, the portfolio managers track financial information
for thousands of individual companies to identify and evaluate trends in
earnings, revenues and other business fundamentals. The portfolio managers'
principal analytical technique involves the identification of companies with
earnings and revenues that are not only growing, but growing at an accelerating
pace. This includes companies whose growth rates, although still negative, are
less negative than prior periods, and companies whose growth rates are expected
to accelerate. In addition to accelerating growth, the fund also considers
companies demonstrating price strength relative to their peers. These techniques
help the portfolio managers buy or hold the stocks of companies they believe
have favorable growth prospects and sell the stocks of companies whose
characteristics no longer meet their criteria.

The fund will usually purchase common stocks of companies that are medium-sized
and smaller at the time of purchase, but it can purchase other types of
securities as well. When determining the size of a company, the portfolio
managers will consider, among other factors, the capitalization of the company
and the amount of revenues as well as other information they obtain about the
company.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies, including
companies located in emerging markets. Investments in foreign securities present
some unique risks that are more fully described in the fund's statement of
additional information.

The portfolio managers do not attempt to time the market. Instead, under normal
market conditions, they intend to keep the fund essentially fully invested in
stocks regardless of the movement of stock prices generally. When the portfolio
managers believe it is prudent, the fund may invest a portion of its assets in
debt securities, options, preferred stock and equity-equivalent securities, such
as convertible securities, stock futures contracts or stock index futures
contracts. The fund generally limits its purchase of debt securities to
investment-grade obligations. Futures contracts, a type of derivative security,
can help the fund's cash assets remain liquid while performing more like stocks.
The fund has a policy governing futures contracts and similar derivative
securities to help manage the risk of these types of investments. A complete
description of the derivatives policy is included in the statement of additional
information.

The fund is not permitted to invest in securities issued by companies assigned
the Global Industry Classification Standard (GICS) for the tobacco industry. If
the


------
6


issuer of a security purchased by the fund is subsequently found to be
classified in the tobacco industry (due to acquisition, merger or otherwise),
the fund will sell the security as soon as reasonably possible.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash, cash-equivalent securities or short-term debt securities. To the extent
the fund assumes a defensive position it will not be pursuing its objective of
long-term capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

The fund generally invests in mid-size and smaller companies, which may be more
volatile and subject to greater short-term risk. Smaller companies may have
limited financial resources, product lines and markets, and their securities may
trade less frequently and in more limited volumes than securities of larger
companies. In addition, smaller companies may have less publicly available
information.

The portfolio managers may buy a large amount of a company's stock quickly, and
often will dispose of it quickly if the company's earnings or revenues decline.
While the portfolio managers believe this strategy provides substantial
appreciation potential over the long term, in the short term it can create a
significant amount of share price volatility. This volatility can be greater
than that of the average stock fund.

The fund's portfolio turnover may be high. This could result in relatively high
commission costs, which could hurt the fund's performance, and capital gains tax
liabilities for the fund's shareholders.

Although the portfolio managers intend to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The fund is not permitted to invest in certain tobacco-related securities. As a
result, the fund may forego a profitable investment opportunity or sell a
security when it may be disadvantageous to do so.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the fund
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the fund to operate.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the fund's management fee may be paid by the fund's
advisor to unaffiliated third parties who provide recordkeeping and
administrative services that would otherwise be performed by an affiliate of the
advisor.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated October 31, 2007.

teams meet regularly to review portfolio holdings and discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit,
guided by the fund's investment objective and strategy.

The portfolio managers on the investment team who are jointly and primarily
responsible for the day-to-day management of the fund are identified below.

Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. In addition, we reserve the right to honor certain redemptions with
securities, rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to a fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.

Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.


------
10


American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

* within seven days of the purchase, or

* within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of each
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. A fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
12


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a "regulated investment company." Qualification as a
regulated investment company means the fund should not be subject to state or
federal income tax on amounts distributed. The distributions generally consist
of dividends and interest received by the fund, as well as CAPITAL GAINS
realized by the fund on the sale of its investment securities. The fund
generally pays distributions from net income and capital gains, if any, once a
year in December. The fund may make more frequent distributions, if necessary,
to comply with Internal Revenue Code provisions.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, to your home address or to another
person or address by check.


------
13


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income they have
received or capital gains they have generated through their investment
activities. Tax consequences also may result when investors sell fund shares
after the net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by a fund from its investments, or capital gains generated by a fund from the
sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY THE FUND FROM
   THE STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT
   THE FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                        TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                    AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains                Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains ( 1 year)
and Qualified Dividend Income           5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
14


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The fund invests primarily in stocks of U.S. companies selected for their above-average growth potential giving consideration to factors such as company management, growth rate of revenues and earnings, opportunities for margin expansion and strong financial characteristics. The fund will normally invest at least 80% of the value of its net assets (plus any borrowings for investment purposes) in stocks of mid-sized companies. The fund considers mid-sized companies to be those with market capitalizations in the range represented by the Russell Midcap® Growth Index. Although the fund's equity investments consist primarily of securities of U.S. issuers, the fund may invest up to 20% of its net assets in the equity securities of issuers from countries outside the United States. The fund's principal risks include * MID CAP STOCKS - The mid-sized companies in which the fund invests may present greater opportunities for capital growth than larger companies, but also may present greater risks. * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 8. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's A Class shares for each full calendar year in the life of the class. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would have been lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. A CLASS(1)

Average Annual Total Returns

The following table shows the average annual total returns of the fund's A Class
shares calculated three different ways. Additional tables show the average
annual total returns of the fund's other share classes calculated before the
impact of taxes. Returns assume the deduction of all sales loads, charges and
other fees associated with a particular class. Your actual returns may vary
depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for A Class shares. After-tax returns for other share
classes will vary.


The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell Midcap® Growth Index
measures the performance of those Russell Midcap Index companies (the 800
smallest of the 1,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth values.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund invests primarily in stocks of U.S. companies selected for their
above-average growth potential giving consideration to factors such as company
management, growth rate of revenues and earnings, opportunities for margin
expansion and strong financial characteristics. The fund will normally invest at
least 80% of the value of its net assets (plus any borrowings for investment
purposes) in stocks of mid-sized companies. The fund may change this 80% policy
only upon 60 days' prior written notice to shareholders. The fund considers
mid-sized companies to be those with market capitalizations in the range
represented by the Russell Midcap Growth Index at the time of purchase. Though
market capitalization may change from time to time, as of December 31, 2007, the
market capitalization range of the Russell Midcap Growth Index was approximately
$624 million to $42 billion.

The fund may sell securities for a variety of reasons such as to secure gains,
limit losses or redeploy assets into more promising opportunities. However, the
fund will not sell a stock just because a mid-sized company in which it invests
has grown into a large-sized company.

Although the fund's equity investments consist primarily of securities of U.S.
issuers, the fund may invest up to 20% of its net assets in the equity
securities of issuers from countries outside the United States , including (i)
foreign securities denominated in a foreign currency and not publicly traded in
the U.S. and (ii) U. S. currency denominated foreign securities, including
depositary receipts and depositary shares issued by U.S. banks (American
Depositary Receipts or ADRs) and U.S. broker-dealers (American Depositary
Shares). The fund's foreign investments may include securities of issuers in
countries with emerging markets or economies. Investments in foreign securities
present some unique risks that are more fully described in the fund's statement
of additional information.

The fund's investments in equity securities may include common stocks, preferred
stocks, warrants, and securities convertible into common or preferred stocks. To
a lesser degree, the fund may invest in other types of securities and use other
investment strategies that may include debt securities, index/structured
securities, high-yield/high-risk bonds, options, futures, forwards, swaps and
other types of derivatives and exchange traded funds, securities purchased on a
when-issued, delayed delivery or forward commitment basis, and pass-through
securities (including mortgage- and asset-backed securities). Futures contracts,
a type of derivative security, can help the fund's cash assets remain liquid
while performing like stocks. The fund has a policy governing futures contracts
and similar derivative securities to help manage the risks of these types of
investments. A complete description of the derivatives policy is included in the
statement of additional information.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash or high-quality short-term debt securities, including money market
reserves. To the extent the fund assumes a defensive position, it will not be
pursuing its objective of capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Mid cap stocks may involve greater risks because the value of securities of
medium size, less well-known issuers can be more volatile than that of
relatively larger issuers and can react differently to issuer, political,
market, and economic developments than the market as a whole and other types of
stocks.

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

Although the portfolio manager intends to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

The fund's performance also may be impacted by investments in initial public
offerings (IPOs). IPOs may present greater risks than other investments in
stocks because the issuers have no track record as public companies. The impact
of IPO investments may be substantial and positive for a relatively small fund
during periods when the IPO market is strong. IPOs may have less performance
impact as the fund's assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate. The advisor has hired Mason Street Advisors, LLC (MSA), a
wholly owned company of The Northwestern Mutual Life Insurance Company
(Northwestern Mutual), to make the day-to-day investment decisions for the fund.
MSA performs this function under the supervision of the advisor and the fund's
Board of Directors. MSA and its predecessor, Northwestern Mutual Investment
Services, LLC, have served as investment advisor to the fund and its predecessor
fund since its inception. The personnel and related facilities of Northwestern
Mutual and MSA are utilized by MSA in performing its investment advisory
functions. The address of MSA is 720 East Wisconsin Avenue, Milwaukee, Wisconsin
53202.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the management fee may be paid by the fund's advisor to
unaffiliated third parties who provide recordkeeping and administrative services
that would otherwise be performed by an affiliate of the advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor, as well as the subadvisory
agreement between the advisor and subadvisor, is available in the fund's report
to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor provides investment advisory and management services for the fund.
The advisor has, in turn, hired MSA to make the day-to-day investment decisions
for the fund. MSA performs this function under the supervision of the advisor
and the fund's Board of Directors.

The portfolio managers on the investment team who are primarily responsible for
the day-to-day management of the fund are identified below.

JILL M. GRUENINGER

Ms. Grueninger, Chartered Financial Analyst, is a co-portfolio manager for the
fund. She is a Managing Director of MSA and joined Northwestern Mutual in May
1990. Ms. Grueninger has a bachelor of business administration degree and an MS
in finance from the University of Wisconsin-Madison, where she also completed
the Applied Securities Analysis Program.

CURTIS LUDWICK

Mr. Ludwick, Chartered Financial Analyst, is a co-portfolio manager for the
fund. He is a Director of MSA and joined Northwestern Mutual in November 1996.
Mr. Ludwick has a bachelor of business administration degree from the University
of Wisconsin-Madison and an MBA degree from the University of
Illinois-Urbana/Champaign.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS,
   INSURANCE COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of
charge and in a clear and prominent format at americancentury.com in the
INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                             AMOUNT PAID TO

$100,000 - $249,999       3.75%            3.90%             3.25%
--------------------------------------------------------------------------------
$250,000 - $499,999       2.50%            2.56%             2.00%

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15



For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of the purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.



REDEMPTION DURING                         CDSC AS A % OF ORIGINAL PURCHASE PRICE
--------------------------------------------------------------------------------
1st year                                  5.00%
--------------------------------------------------------------------------------
2nd year                                  4.00%
--------------------------------------------------------------------------------
3rd year                                  3.00%
--------------------------------------------------------------------------------
4th year                                  3.00%
--------------------------------------------------------------------------------
5th year                                  2.00%
--------------------------------------------------------------------------------
6th year                                  1.00%
--------------------------------------------------------------------------------
After 6th year                            None
--------------------------------------------------------------------------------

B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).

CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market
      value for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market
      value for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class shares
   and for C Class shares


------
17


*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.

EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of the fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.


------
18





BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts

--------------------------------------------------------------------------------
Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.



------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.


   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining investors.

21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of the fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to the fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
22


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs
   that may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

The fund generally pays distributions from net income and capital gains, if any,
once a year in December. It may make more frequent distributions, if necessary,
to comply with Internal Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE
   STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE
   FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                       TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                   AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains               Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains (1 year)
and Qualified Dividend Income          5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that the fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

28


MULTIPLE CLASS INFORMATION


American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except Investor Class and Institutional Class, offered
by this prospectus has a 12b-1 plan. The plans provide for the fund to pay
annual fees of 0.25% for A Class, 1.00% for B and C Classes, and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.



------
29



Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

American Century Investment Services, Inc., Distributor ©2008 American Century Proprietary Holdings, Inc. All rights reserved. AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks long-term capital growth.
WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? Securities are selected for their above-average growth potential giving consideration to factors such as company management, growth rate of revenues and earnings, opportunities for margin expansion and strong financial characteristics. The fund will normally invest at least 80% of the value of its net assets (plus any borrowings for investment purposes) in common stocks of small cap companies. The fund considers small cap companies to be those with market capitalizations that do not exceed the maximum market capitalization of any security in the Russell 2000(®) Growth Index. The fund also may invest in equity securities of companies with stock market capitalizations less than $500 million at the time of investment (micro cap companies). Although the fund's equity investments consist primarily of securities of U.S. issuers, the fund may invest up to 20% of its net assets in the equity securities of issuers from countries outside the United States. The fund's principal risks include * SMALL CAP STOCKS - The smaller companies in which the fund invests may present greater opportunities for capital growth than larger companies, but also may present greater risks. * GROWTH STOCKS - Investments in growth stocks may involve special risks and their prices may fluctuate more dramatically than the overall stock market. * FOREIGN SECURITIES - The fund may invest in foreign securities, which can be riskier than investing in U.S. securities. * IPO RISK - The fund's performance may be affected by investments in initial public offerings. * MARKET RISK - The value of the fund's shares will go up and down based on the performance of the companies whose securities it owns and other factors generally affecting the securities market. * PRICE VOLATILITY - The value of the fund's shares may fluctuate significantly in the short term. * PRINCIPAL LOSS - At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the fund. A more detailed description of the fund's investment strategies and risks may be found under the heading OBJECTIVES, STRATEGIES AND RISKS, which begins on page 8. [GRAPHIC OF TRIANGLE] AN INVESTMENT IN THE FUND IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER GOVERNMENT AGENCY. ------ 2 FUND PERFORMANCE HISTORY Annual Total Returns The following bar chart shows the performance of the fund's A Class shares for each full calendar year in the life of the class. It indicates the volatility of the fund's historical returns from year to year. Account fees and sales charges, if applicable, are not reflected in the chart below. If they had been included, returns would have been lower than those shown. The returns of the fund's other classes of shares will differ from those shown in the chart, depending on the expenses of those classes. A CLASS(1)

     CAP GROWTH STOCK FUND ON MARCH 31, 2006, PURSUANT TO A PLAN OF

     2006. PERFORMANCE INFORMATION PRIOR TO APRIL 1, 2006, IS THAT OF THE MASON
     STREET SMALL CAP GROWTH STOCK FUND.

The highest and lowest quarterly returns for the periods reflected in the bar
chart are:

Average Annual Total Returns

The following table shows the average annual total returns of the fund's A Class
shares calculated three different ways. Additional tables show the average
annual total returns of the fund's other share classes calculated before the
impact of taxes. Returns assume the deduction of all sales loads, charges and
other fees associated with a particular class. Your actual returns may vary
depending on the circumstances of your investment.

Return Before Taxes shows the actual change in the value of fund shares over the
time periods shown, but does not reflect the impact of taxes on fund
distributions or the sale of fund shares. The two after-tax returns take into
account taxes that may be associated with owning fund shares. Return After Taxes
on Distributions is a fund's actual performance, adjusted by the effect of taxes
on distributions made by the fund during the periods shown. Return After Taxes
on Distributions and Sale of Fund Shares is further adjusted to reflect the tax
impact on any change in the value of fund shares as if they had been sold on the
last day of the period.


------

After-tax returns are calculated using the historical highest federal marginal
income tax rates and do not reflect the impact of state and local taxes. Actual
after-tax returns depend on an investor's tax situation and may differ from
those shown. After-tax returns shown are not relevant to investors who hold fund
shares through tax-deferred arrangements such as 401(k) plans or IRAs. After-tax
returns are shown only for A Class shares. After-tax returns for other share
classes will vary.

The benchmark is an unmanaged index that has no operating costs and is included
in each table for performance comparison. The Russell 2000® Growth Index
measures the performance of those Russell 2000 Index companies (the 2,000
smallest of the 3,000 largest publicly traded U.S. companies, based on total
market capitalization) with higher price-to-book ratios and higher forecasted
growth rates.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks long-term capital growth.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

Securities are selected for their above-average growth potential giving
consideration to factors such as company management, growth rate of revenues and
earnings, opportunities for margin expansion and strong financial
characteristics. The fund will normally invest at least 80% of the value of its
net assets (plus any borrowings for investment purposes) in common stocks of
small cap companies. The fund may change this 80% policy only upon 60 days'
prior written notice to shareholders. The fund considers small cap companies to
be those with market capitalizations that do not exceed the maximum market
capitalization of any security in the Russell 2000 Growth Index at the time of
purchase (which as of December 31, 2007, was approximately $8.398 billion). The
fund also may invest in equity securities of companies with stock market
capitalizations less than $500 million at the time of investment (micro cap
companies).

On occasion, the fund may purchase companies with a market capitalization of
more than the largest company in the Index. Additionally, the market cap of
companies in the fund and the Index will change over time due to market forces
and periodic rebalancing of the Index. The fund will not sell a stock just
because the company has grown to a market capitalization of more than the
largest company in the Russell 2000 Growth Index.

The fund may sell securities for a variety of reasons such as to secure gains,
limit losses or redeploy assets into more promising opportunities.

Although the fund's equity investments consist primarily of securities of U.S.
issuers, the fund may invest up to 20% of its net assets in the equity
securities of issuers from countries outside the United States, including (i)
foreign securities denominated in a foreign currency and not publicly traded in
the U.S. and (ii) U. S. currency denominated foreign securities, including
depositary receipts and depositary shares issued by U.S. banks (American
Depositary Receipts or ADRs) and U.S. broker-dealers (American Depositary
Shares). The fund's foreign investments may include securities of issuers in
countries with emerging markets or economies. Investments in foreign securities
present some unique risks that are more fully described in the fund's statement
of additional information.

The fund's investments in equity securities may include common stocks, preferred
stocks, warrants, and securities convertible into common or preferred stocks. To
a lesser degree, the fund may invest in other types of securities and use other
investment strategies that may include debt securities, index/structured
securities, high-yield/high-risk bonds, options, futures, forwards, swaps and
other types of derivatives and exchange traded funds, securities purchased on a
when-issued, delayed delivery or forward commitment basis, and pass-through
securities (including mortgage- and asset-backed securities). Futures contracts,
a type of derivative security, can help the fund's cash assets remain liquid
while performing like stocks. The fund has a policy governing futures contracts
and similar derivative securities to help manage the risks of these types of
investments. A complete description of the derivatives policy is included in the
statement of additional information.


------

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash or high-quality short-term debt securities, including money market
reserves. To the extent the fund assumes a defensive position, it will not be
pursuing its objective of capital growth.

A description of the policies and procedures with respect to the disclosure of
the fund's portfolio securities is available in the statement of additional
information.




WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Small cap stocks may involve greater risks because smaller companies often have
a limited track record, narrower markets and more limited managerial and
financial resources than larger, more established companies. The prices of these
stocks tend to be more volatile and the issuers face greater risk of business
failure.

Micro cap stocks may involve greater risks because the prices of micro cap
securities are generally even more volatile and their markets are even less
liquid relative to both small cap and large cap securities.

Growth stocks are typically priced higher than other stocks, in relation to
earnings and other measures, because investors believe they have more growth
potential. This potential may or may not be realized and growth stock prices
tend to fluctuate more dramatically than the overall stock market.

Although the portfolio manager intends to invest the fund's assets primarily in
U.S. stocks, the fund may invest in securities of foreign companies. Foreign
investment involves additional risks, including fluctuations in currency
exchange rates, less stable political and economic structures, reduced
availability of public information, and lack of uniform financial reporting and
regulatory practices similar to those that apply in the United States. These
factors make investing in foreign securities generally riskier than investing in
U.S. stocks. To the extent the fund invests in foreign securities, the overall
risk of that fund could be affected.

The fund's performance also may be impacted by investments in initial public
offerings (IPOs). IPOs may present greater risks than other investments in
stocks because the issuers have no track record as public companies. The impact
of IPO investments may be substantial and positive for a relatively small fund
during periods when the IPO market is strong. IPOs may have less performance
impact as the fund's assets grow.

Market performance tends to be cyclical, and, in the various cycles, certain
investment styles may fall in and out of favor. If the market is not favoring
the fund's style, the fund's gains may not be as big as, or its losses may be
bigger than, other equity funds using different investment styles.

The value of the fund's shares depends on the value of the stocks and other
securities it owns. The value of the individual securities the fund owns will go
up and down depending on the performance of the companies that issued them,
general market and economic conditions, and investor confidence.

At any given time your shares may be worth less than the price you paid for
them. In other words, it is possible to lose money by investing in the fund.

MANAGEMENT

WHO MANAGES THE FUND?

The Board of Directors, investment advisor and fund management team play key
roles in the management of the fund.




THE BOARD OF DIRECTORS

The Board of Directors oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Directors does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the directors are independent of the fund's advisor;
that is, they have never been employed by and have no financial interest in the
advisor or any of its affiliated companies (other than as shareholders of
American Century funds).




THE INVESTMENT ADVISOR

The fund's investment advisor is American Century Investment Management, Inc.
(the advisor). The advisor has been managing mutual funds since 1958 and is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolio of the fund and
directing the purchase and sale of its investment securities. The advisor also
arranges for transfer agency, custody and all other services necessary for the
fund to operate. The advisor has hired Mason Street Advisors, LLC (MSA), a
wholly owned company of The Northwestern Mutual Life Insurance Company
(Northwestern Mutual), to make the day-to-day investment decisions for the fund.
MSA performs this function under the supervision of the advisor and the fund's
Board of Directors. MSA and its predecessor, Northwestern Mutual Investment
Services, LLC, have served as investment advisor to the fund and its predecessor
fund since its inception. The personnel and related facilities of Northwestern
Mutual and MSA are utilized by MSA in performing its investment advisory
functions. The address of MSA is 720 East Wisconsin Avenue, Milwaukee, Wisconsin
53202.

For the services it provides to the fund, the advisor receives a unified
management fee based on a percentage of the daily net assets of each class of
shares of the fund. The amount of the fee is calculated daily and paid monthly
in arrears. Out of that fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent directors (including legal counsel fees), and extraordinary
expenses. A portion of the management fee may be paid by the fund's advisor to
unaffiliated third parties who provide recordkeeping and administrative services
that would otherwise be performed by an affiliate of the advisor.

The rate of the fee is determined by applying a formula that takes into account
all of the advisor's assets under management in the fund's investment strategy
(strategy assets). Strategy assets include the assets of the fund as well as
certain assets of other clients of the advisor outside the American Century fund
family (such as subadvised funds and separate accounts) that use very similar
investment teams and strategies. The use of strategy assets, rather than fund
assets, in calculating the fund's fee rate could allow the fund to realize
scheduled cost savings more quickly. However, the fund's strategy assets
currently do not include assets of other client accounts. In addition, if such
assets are acquired in the future, they may not be sufficient to result in a
lower fee rate.

A discussion regarding the basis for the Board of Directors' approval of the
fund's investment advisory contract with the advisor, as well as the subadvisory
agreement between the advisor and subadvisor, is available in the fund's report
to shareholders dated October 31, 2007.

THE FUND MANAGEMENT TEAM

The advisor provides investment advisory and management services for the fund.
The advisor has, in turn, hired MSA to make the day-to-day investment decisions
for the fund. MSA performs this function under the supervision of the advisor
and the fund's Board of Directors.

The portfolio managers on the investment team who are primarily responsible for
the day-to-day management of the fund are identified below.

WILLIAM R. WALKER

Mr. Walker, Chartered Financial Analyst, is a co-portfolio manager for the fund.
He is a Managing Director of MSA and joined Northwestern Mutual in April 1984.
Mr. Walker has a bachelor's degree in business administration with an emphasis
in finance from Marquette University and an MBA from Miami University of Oxford,
Ohio.

ANDY ENG

Mr. Eng, Chartered Financial Analyst, is a co-portfolio manager for the fund. He
joined Northwestern Mutual in May 2000 and has been a Director of MSA since
2004. Mr. Eng has a bachelor of science degree in finance and economics from the
University of Illinois-Urbana and an MBA in finance from Washington University
in St. Louis.

The statement of additional information provides additional information about
the accounts managed by the portfolio managers, the structure of their
compensation, and their ownership of fund securities.




FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the statement of additional
information and the investment objectives of the fund may not be changed without
shareholder approval. The Board of Directors and/or the advisor may change any
other policies and investment strategies.

INVESTING THROUGH A FINANCIAL INTERMEDIARY

The fund's A, C and R Classes are intended for purchase by participants in
employer-sponsored retirement plans. Additionally, the fund's A, B and C Classes
are intended for persons purchasing shares through FINANCIAL INTERMEDIARIES that
provide various administrative and distribution services. For more information
regarding employer-sponsored retirement plan types, please see BUYING AND
SELLING FUND SHARES in the statement of additional information.

   [GRAPHIC OF TRIANGLE]

   FINANCIAL INTERMEDIARIES INCLUDE BANKS, BROKER-DEALERS, INSURANCE
   COMPANIES, PLAN SPONSORS AND FINANCIAL PROFESSIONALS.

Although each class of shares represents an interest in the same fund, each has
a different cost structure, as described below. Which class is right for you
depends on many factors, including how long you plan to hold the shares, how
much you plan to invest, the fee structure of each class, and how you wish to
compensate your financial professional for the services provided to you. Your
financial professional can help you choose the option that is most appropriate.

The following table provides a summary description of these classes.

CALCULATION OF SALES CHARGES

The information regarding sales charges provided herein is included free of

INVESTORS USING ADVISORS and INVESTMENT PROFESSIONALS portions of the Web site.
From the description of A, B or C Class shares, a hyperlink will take you
directly to this disclosure.



A Class

A Class shares are sold at their offering price, which is net asset value plus
an initial sales charge. This sales charge varies depending on the amount of
your investment, and is deducted from your purchase before it is invested. The
sales charges and the amounts paid to your financial professional are:

                                                             AMOUNT PAID

--------------------------------------------------------------------------------


(1)  FOR PURCHASES OVER $1,000,000 BY EMPLOYER-SPONSORED RETIREMENT PLANS,
     NO UPFRONT AMOUNT WILL BE PAID TO FINANCIAL PROFESSIONALS.

There is no front-end sales charge for purchases of $1,000,000 or more, but if
you redeem your shares within one year of purchase you will pay a 1.00% deferred
sales charge, subject to the exceptions listed below. No sales charge applies to
reinvested dividends.

Reductions and Waivers of Sales Charges for A Class

You may qualify for a reduction or waiver of certain sales charges, but you or
your financial professional must provide certain information, including the
account numbers of any accounts to be aggregated, to American Century at the
time of purchase in order to take advantage of such reduction or waiver. If you
hold assets among multiple intermediaries, it is your responsibility to inform
your intermediary and/or American Century at the time of purchase of any
accounts to be aggregated.

You and your immediate family (your spouse and your children under the age of
21) may combine investments in any share class of any American Century fund
(excluding 529 account assets and certain assets in money market accounts) to
reduce your A Class sales charge in the following ways:

ACCOUNT AGGREGATION. Investments made by you and your immediate family may be
aggregated at each account's current market value if made for your own
account(s) and/or certain other accounts, such as:

*  Certain trust accounts

*  Solely controlled business accounts

*  Single-participant retirement plans

*  Endowments or foundations established and controlled by you or an
   immediate family member


------
15



For purposes of aggregation, only investments made through individual-level
accounts may be combined. Assets held in multiple participant employer-sponsored
retirement plans may be aggregated at a plan level.

CONCURRENT PURCHASES. You may combine simultaneous purchases in any share class
of any American Century fund to qualify for a reduced A Class sales charge.

RIGHTS OF ACCUMULATION. You may take into account the current value of your
existing holdings, less any commissionable shares in the money market funds, in
any share class of any American Century fund to qualify for a reduced A Class
sales charge.

LETTER OF INTENT. A Letter of Intent allows you to combine all non-money market
fund purchases of any share class of any American Century fund you intend to
make over a 13-month period to determine the applicable sales charge. At your
request, existing holdings may be combined with new purchases and sales charge
amounts may be adjusted for purchases made within 90 days prior to our receipt
of the Letter of Intent. Capital appreciation, capital gains and reinvested
dividends earned during the Letter of Intent period do not apply toward its
completion. A portion of your account will be held in escrow to cover additional
A Class sales charges that will be due if your total investments over the
13-month period do not qualify for the applicable sales charge reduction.

WAIVERS FOR CERTAIN INVESTORS. The sales charge on A Class shares may be waived
for:

*  Purchases by registered representatives and other employees of certain
   financial intermediaries (and their immediate family members) having selling
   agreements with the advisor or distributor

*  Broker-dealer sponsored wrap program accounts and/or fee-based accounts
   maintained for clients of certain financial intermediaries who have entered
   into selling agreements with American Century

*  Present or former officers, directors and employees (and their families)
   of American Century

*  Employer-sponsored retirement plan purchases. For plans under $1 million
   in assets, purchases with sales charges are allowed, but may be subject to
   the retirement plan recordkeeper's policies. Refer to BUYING AND SELLING FUND
   SHARES in the statement of additional information

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan

*  Certain other investors as deemed appropriate by American Century

B Class

B Class shares are sold at their net asset value without an initial sales
charge. For sales of B Class shares, the amount paid to your financial
professional is 4.00% of the amount invested. If you redeem your shares within
six years of the purchase date, you will pay a contingent deferred sales charge
(CDSC) as set forth below. The purpose of the CDSC is to permit the fund's
distributor to recoup all or a portion of the up-front payment made to your
financial professional. There is no CDSC on shares acquired through reinvestment
of dividends or capital gains.

B Class shares (which carry a 1.00% 12b-1 fee) will automatically convert to A
Class shares (which carry a 0.25% 12b-1 fee) within 31 days after the eight-year
anniversary of the purchase date.

American Century generally limits purchases of B Class shares to investors whose
aggregate investments in American Century funds are less than $50,000. However,
it is your responsibility to inform your financial intermediary and/or American
Century at the time of purchase of any accounts to be aggregated, including
investments in any share class of any American Century fund (excluding 529
account assets and certain assets in money market accounts) in accounts held by
you and your immediate family members (your spouse and children under the age of
21). Once you reach this limit, you should work with your financial intermediary
to determine what share class is most appropriate for additional purchases.

C Class

C Class shares are sold at their net asset value without an initial sales
charge. For sales of C Class shares, the amount paid to your financial
professional is 1.00% of the amount invested. If you redeem your shares within
12 months of purchase, you will pay a CDSC of 1.00% of the original purchase
price or the current market value at redemption, whichever is less. The purpose
of the CDSC is to permit the fund's distributor to recoup all or a portion of
the up-front payment made to your financial professional. There is no CDSC on
shares acquired through reinvestment of dividends or capital gains.

American Century generally limits purchases of C Class shares to investors whose
aggregate investments in American Century funds are less than $1,000,000.
However, it is your responsibility to inform your financial intermediary and/or
American Century at the time of purchase of any accounts to be aggregated,
including investments in any share class of any American Century fund (excluding
529 account assets and certain assets in money market accounts) in accounts held
by you and your immediate family members (your spouse and children under the age
of 21). Once you reach this limit, you should work with your financial
intermediary to determine what share class is most appropriate for additional
purchases.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE (CDSC)

To minimize the amount of the CDSC you may pay when you redeem shares, the fund
will first redeem shares acquired through reinvested dividends and capital gain
distributions, which are not subject to a CDSC. Shares that have been in your
account long enough that they are not subject to a CDSC are redeemed next. For
any remaining redemption amount, shares will be sold in the order they were
purchased (earliest to latest).


------

CDSC WAIVERS

Any applicable CDSC may be waived in the following cases:

*  redemptions through systematic withdrawal plans not exceeding annually:

   *  12% of the lesser of the original purchase cost or current market
      value for A Class shares

   *  12% of the original purchase cost for B Class shares

   *  12% of the lesser of the original purchase cost or current market
      value for C Class shares

*  distributions from IRAs due to attainment of age 59-1/2 for A Class
   shares and for C Class shares

*  required minimum distributions from retirement accounts upon reaching age
   70-1/2

*  tax-free returns of excess contributions to IRAs

*  redemptions due to death or post-purchase disability

*  exchanges, unless the shares acquired by exchange are redeemed within the
   original CDSC period

*  IRA Rollovers from any American Century fund held in an employer-sponsored
   retirement plan, for A Class shares only

*  if no broker was compensated for the sale

REINSTATEMENT PRIVILEGE

Within 90 days of a redemption of any A or B Class shares, you may reinvest all
of the redemption proceeds in A Class shares of any American Century fund at the
then-current net asset value without paying an initial sales charge. At your
request, any CDSC you paid on an A Class redemption that you are reinvesting
will be credited to your account. You or your financial professional must notify
the fund's transfer agent in writing at the time of the reinvestment to take
advantage of this privilege, and you may use it only once per account. This
privilege applies only if the new account is owned by the original account
owner.

EXCHANGING SHARES

You may exchange shares of the fund for shares of the same class of another
American Century fund without a sales charge if you meet the following criteria:

*  The exchange is for a minimum of $100

*  For an exchange that opens a new account, the amount of the exchange must
   meet or exceed the minimum account size requirement for the fund receiving
   the exchange

For purposes of computing any applicable CDSC on shares that have been
exchanged, the holding period will begin as of the date of purchase of the
original fund owned. Exchanges from a money market fund are subject to a sales
charge on the fund being purchased, unless the money market fund shares were
acquired by exchange from a fund with a sales charge or by reinvestment of
dividends or capital gains distributions.


------
18


EXCHANGES BETWEEN FUNDS (C CLASS)

You may exchange C Class shares of the fund for C Class shares of any other
American Century fund. You may not exchange from the C Class to any other class.
We will not charge a CDSC on the shares you exchange, regardless of the length
of time you have owned them. When you do redeem shares that have been exchanged,
the CDSC will be based on the date you purchased the original shares.




BUYING AND SELLING SHARES

Your ability to purchase, exchange, redeem and transfer shares will be affected
by the policies of the financial intermediary through which you do business.
Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments

*  trading restrictions

In addition, your financial intermediary may charge a transaction fee for the
purchase or sale of fund shares. Those charges are retained by the financial
intermediary and are not shared with American Century or the fund. Please
contact your financial intermediary or plan sponsor for a complete description
of its policies. Copies of the fund's annual report, semiannual report and
statement of additional information are available from your financial
intermediary or plan sponsor.

The fund has authorized certain financial intermediaries to accept orders on the
fund's behalf. American Century has selling agreements with these financial
intermediaries requiring them to track the time investment orders are received
and to comply with procedures relating to the transmission of orders. Orders
must be received by the financial intermediary on the fund's behalf before the
time the net asset value is determined in order to receive that day's share
price. If those orders are transmitted to American Century and paid for in
accordance with the selling agreement, they will be priced at the net asset
value next determined after your request is received in the form required by the
financial intermediary.

ADDITIONAL POLICIES AFFECTING YOUR INVESTMENT

ELIGIBILITY FOR INVESTOR CLASS SHARES

The fund's Investor Class shares are available for purchase through financial
intermediaries in the following types of accounts:

*  employer-sponsored retirement plans

*  broker-dealer sponsored fee-based wrap programs or other fee-based
   advisory accounts

*  insurance products and bank/trust products where fees are being charged

The fund's Investor Class shares also are available for purchase directly from
American Century by:

*  shareholders who held any account directly with American Century as of
   September 28, 2007, and have continuously maintained such account (this
   includes anyone listed in the registration of an account, such as joint
   owners, trustees or custodians, and the immediate family members of such
   persons)

*  current or retired employees of American Century and their immediate
   family members, and directors of the fund

Investors may be required to demonstrate eligibility to purchase Investor Class
shares of the fund before an investment is accepted. The fund reserves the
right, when in the judgment of American Century it is not adverse to the fund's
interest, to permit all or only certain types of investors to open new accounts
in the fund, to impose further restrictions, or to close the fund to any
additional investments, all without notice.



MINIMUM INITIAL INVESTMENT AMOUNTS (OTHER THAN INSTITUTIONAL CLASS)

Unless otherwise specified below, the minimum initial investment amount to open
an account is $2,500. Financial intermediaries may open an account with $250,
but may require their clients to meet different investment minimums. See
INVESTING THROUGH A FINANCIAL INTERMEDIARY for more information.

--------------------------------------------------------------------------------
Broker-dealer sponsored wrap program                                  No minimum
accounts and/or fee-based accounts
--------------------------------------------------------------------------------
Coverdell Education Savings Account (CESA)                            $2,000(1)

Employer-sponsored retirement plans                                   No minimum
--------------------------------------------------------------------------------


(1)  THE MINIMUM INITIAL INVESTMENT FOR FINANCIAL INTERMEDIARIES IS $250.
     FINANCIAL INTERMEDIARIES MAY HAVE DIFFERENT MINIMUMS FOR THEIR CLIENTS.

SUBSEQUENT PURCHASES

There is a $50 minimum for subsequent purchases. See WAYS TO MANAGE YOUR ACCOUNT
for more information about making additional investments directly with American
Century. However, there is no subsequent purchase minimum for financial
intermediaries or employer-sponsored retirement plans, but financial
intermediaries may require their clients to meet different subsequent purchase
requirements.

ELIGIBILITY FOR INSTITUTIONAL CLASS SHARES

The Institutional Class shares are made available for purchase by individuals
and large institutional shareholders such as bank trust departments,
corporations, retirement plans, endowments, foundations and financial advisors
that meet the fund's minimum investment requirements. Institutional Class shares
are not available for purchase by insurance companies for variable annuity and
variable life products.


------
20


MINIMUM INITIAL INVESTMENT AMOUNTS (INSTITUTIONAL CLASS)

The minimum initial investment amount is $5 million ($3 million for endowments
and foundations) per fund. If you invest with us through a financial
intermediary, this requirement may be met if your financial intermediary
aggregates your investments with those of other clients into a single group, or
omnibus, account that meets the minimum. The minimum investment requirement may
be waived if you, or your financial intermediary if you invest through an
omnibus account, have an aggregate investment in our family of funds of $10
million or more ($5 million for endowments and foundations), or in other
situations as determined by American Century. In addition, financial
intermediaries or plan recordkeepers may require retirement plans to meet
certain other conditions, such as plan size or a minimum level of assets per
participant, in order to be eligible to purchase Institutional Class shares.

REDEMPTIONS

If you sell B, C or, in certain cases, A Class shares, you may pay a sales
charge, depending on how long you have held your shares, as described above.
Your redemption proceeds will be calculated using the NET ASSET VALUE (NAV) next
determined after we receive your transaction request in good order.

   [GRAPHIC OF TRIANGLE]




   A FUND'S NET ASSET VALUE, OR NAV, IS THE PRICE OF THE FUND'S SHARES.

However, we reserve the right to delay delivery of redemption proceeds up to
seven days. For example, each time you make an investment with American Century,
there is a seven-day holding period before we will release redemption proceeds
from those shares, unless you provide us with satisfactory proof that your
purchase funds have cleared. Investments by wire generally require only a
one-day holding period. If you change your address, we may require that any
redemption request made within 15 days be submitted in writing and be signed by
all authorized signers with their signatures guaranteed. If you change your bank
information, we may impose a 15-day holding period before we will transfer or
wire redemption proceeds to your bank. Please remember, if you request
redemptions by wire, $10 will be deducted from the amount redeemed. Your bank
also may charge a fee.

In addition, we reserve the right to honor certain redemptions with securities,
rather than cash, as described in the next section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS

If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the value of a fund's assets if that amount is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. The portfolio
managers would select these securities from the fund's portfolio.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, you may have to pay
brokerage or other transaction costs to convert the securities to cash.

If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining investors.


------
21


REDEMPTION OF SHARES IN ACCOUNTS BELOW MINIMUM

If your account balance falls below the minimum initial investment amount for
any reason other than as a result of market fluctuation, American Century
reserves the right to redeem the shares in the account and send the proceeds to
your address of record. Prior to doing so, we will notify you and give you 90
days to meet the minimum. Please note that shares redeemed in this manner may be
subject to a sales charge if held less than the applicable time period. You also
may incur tax liability as a result of the redemption. For Institutional Class
shares, we reserve the right to convert your shares to Investor Class shares of
the same fund. The Investor Class shares have a unified management fee that is
0.20% higher than the Institutional Class.

SIGNATURE GUARANTEES

A signature guarantee - which is different from a notarized signature - is a
warranty that the signature presented is genuine. We may require a signature
guarantee for the following transactions.

*  You have chosen to conduct business in writing only and would like to
   redeem over $100,000.

*  Your redemption or distribution check, Check-A-Month or automatic
   redemption is made payable to someone other than the account owners.

*  Your redemption proceeds or distribution amount is sent by EFT (ACH or
   wire) to a destination other than your personal bank account.

*  You are transferring ownership of an account over $100,000.

*  You change your address and request a redemption over $100,000 within 15
   days.

*  You change your bank information and request a redemption within 15 days.

We reserve the right to require a signature guarantee for other transactions, at
our discretion.

MODIFYING OR CANCELING AN INVESTMENT

Investment instructions are irrevocable. That means that once you have mailed or
otherwise transmitted your investment instruction, you may not modify or cancel
it. The fund reserves the right to suspend the offering of shares for a period
of time and to reject any specific investment (including a purchase by
exchange). Additionally, we may refuse a purchase if, in our judgment, it is of
a size that would disrupt the management of the fund.

ABUSIVE TRADING PRACTICES

Short-term trading and other so-called market timing practices are not defined
or explicitly prohibited by any federal or state law. However, short-term
trading and other abusive trading practices may disrupt portfolio management
strategies and harm fund performance. If the cumulative amount of short-term
trading activity is significant relative to the fund's net assets, the fund may
incur trading costs that are higher than necessary as securities are first
purchased then quickly sold to meet the redemption request. In such case, the
fund's performance could be negatively impacted by the increased trading costs
created by short-term trading if the additional trading costs are significant.


------
22


Because of the potentially harmful effects of abusive trading practices, the
fund's Board of Directors has approved American Century's abusive trading
policies and procedures, which are designed to reduce the frequency and effect
of these activities in our funds. These policies and procedures include
monitoring trading activity, imposing trading restrictions on certain accounts,
imposing redemption fees on certain funds, and using fair value pricing when
current market prices are not readily available. Although these efforts are
designed to discourage abusive trading practices, they cannot eliminate the
possibility that such activity will occur. American Century seeks to exercise
its judgment in implementing these tools to the best of its ability in a manner
that it believes is consistent with shareholder interests.

American Century uses a variety of techniques to monitor for and detect abusive
trading practices. These techniques may vary depending on the type of fund, the
class of shares or whether the shares are held directly or indirectly with
American Century. They may change from time to time as determined by American
Century in its sole discretion. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including
exchanges) from any shareholder we believe has a history of abusive trading or
whose trading, in our judgment, has been or may be disruptive to the funds. In
making this judgment, we may consider trading done in multiple accounts under
common ownership or control.

Currently, for shares held directly with American Century, we may deem the sale
of all or a substantial portion of a shareholder's purchase of fund shares to be
abusive if the sale is made

*  within seven days of the purchase, or

*  within 30 days of the purchase, if it happens more than once per year.

To the extent practicable, we try to use the same approach for defining abusive
trading for shares held through financial intermediaries. American Century
reserves the right, in its sole discretion, to identify other trading practices
as abusive and to modify its monitoring and other practices as necessary to deal
with novel or unique abusive trading practices.

In addition, American Century reserves the right to accept purchases and
exchanges in excess of the trading restrictions discussed above if it believes
that such transactions would not be inconsistent with the best interests of fund
shareholders or this policy.

American Century's policies do not permit us to enter into arrangements with
fund shareholders that permit such shareholders to engage in frequent purchases
and redemptions of fund shares. Due to the complexity and subjectivity involved
in identifying abusive trading activity and the volume of shareholder
transactions American Century handles, there can be no assurance that American
Century's efforts will identify all trades or trading practices that may be
considered abusive. American Century monitors aggregate trades placed in omnibus
accounts and works with financial intermediaries to identify shareholders
engaging in abusive trading practices and impose restrictions to discourage such
practices. Because American Century relies on financial intermediaries to
provide information and impose restrictions, our ability to monitor and
discourage abusive trading practices in omnibus accounts may be dependent upon
the intermediaries' timely performance of such duties.

23


YOUR RESPONSIBILITY FOR UNAUTHORIZED TRANSACTIONS

American Century and its affiliated companies use procedures reasonably designed
to confirm that telephone, electronic and other instructions are genuine. These
procedures include recording telephone calls, requesting personalized security
codes or other information, and sending confirmation of transactions. If we
follow these procedures, we are not responsible for any losses that may occur
due to unauthorized instructions. For transactions conducted over the Internet,
we recommend the use of a secure Internet browser. In addition, you should
verify the accuracy of your confirmation statements immediately after you
receive them.

A NOTE ABOUT MAILINGS TO SHAREHOLDERS

To reduce the amount of mail you receive from us, we may deliver a single copy
of certain investor documents (such as shareholder reports and prospectuses) to
investors who share an address, even if accounts are registered under different
names. If you prefer to receive multiple copies of these documents individually
addressed, please call us or your financial professional. For American Century
Brokerage accounts, please call 1-888-345-2071.

RIGHT TO CHANGE POLICIES

We reserve the right to change any stated investment requirement, including
those that relate to purchases, exchanges and redemptions. We also may alter,
add or discontinue any service or privilege. Changes may affect all investors or
only those in certain classes or groups. In addition, from time to time we may
waive a policy on a case-by-case basis, as the advisor deems appropriate.

24





SHARE PRICE AND DISTRIBUTIONS




SHARE PRICE

American Century will price the fund shares you purchase, exchange or redeem at
the net asset value (NAV) next determined after your order is received and
accepted by the fund's transfer agent, or other financial intermediary with the
authority to accept orders on the fund's behalf. We determine the NAV of the
fund as of the close of regular trading (usually 4 p.m. Eastern time) on the New
York Stock Exchange (NYSE) on each day the NYSE is open. On days when the NYSE
is closed (including certain U.S. national holidays), we do not calculate the
NAV. The fund's NAV is the current value of the fund's assets, minus any
liabilities, divided by the number of shares outstanding.

The fund values portfolio securities for which market quotations are readily
available at their market price. As a general rule, equity securities listed on
a U.S. exchange are valued at the last current reported sale price as of the
time of valuation. Securities listed on the NASDAQ National Market System
(Nasdaq) are valued at the Nasdaq Official Closing Price (NOCP), as determined
by Nasdaq, or lacking an NOCP, at the last current reported sale price as of the
time of valuation. The fund may use pricing services to assist in the
determination of market value. Unlisted securities for which market quotations
are readily available are valued at the last quoted sale price or the last
quoted ask price, as applicable, except that debt obligations with 60 days or
less remaining until maturity may be valued at amortized cost. Exchange-traded
options, futures and options on futures are valued at the settlement price as
determined by the appropriate clearing corporation.

If the fund determines that the market price for a portfolio security is not
readily available or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued as determined in good faith
by the fund's board or its designee, in accordance with procedures adopted by
the fund's board. Circumstances that may cause the fund to use alternate
procedures to value a security include, but are not limited to:

*  if, after the close of the foreign exchange on which a portfolio security
   is principally traded, but before the close of the NYSE, an event occurs that
   may materially affect the value of the security;

*  a debt security has been declared in default; or

*  trading in a security has been halted during the trading day.

If such circumstances occur, the fund will fair value the security if the fair
valuation would materially impact the fund's NAV. While fair value
determinations involve judgments that are inherently subjective, these
determinations are made in good faith in accordance with procedures adopted by
the fund's board.

The effect of using fair value determinations is that the fund's NAV will be
based, to some degree, on security valuations that the board or its designee
believes are fair rather than being solely determined by the market.

With respect to any portion of the fund's assets that are invested in one or
more open-end management investment companies that are registered with the SEC
(known as registered investment companies, or RICs), the fund's NAV will be
calculated based upon the NAVs of such RICs. These RICs are required by law to
explain the circumstances under which they will use fair value pricing and the
effects of using fair value pricing in their prospectuses.


------
25


Securities and other assets quoted in foreign currencies are valued in U.S.
dollars based on the prevailing exchange rates on that day.

Trading of securities in foreign markets may not take place every day the NYSE
is open. Also, trading in some foreign markets and on some electronic trading
networks may take place on weekends or holidays when the fund's NAV is not
calculated. So, the value of the fund's portfolio may be affected on days when
you will not be able to purchase, exchange or redeem fund shares.

DISTRIBUTIONS

Federal tax laws require the fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the fund should not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received by the fund, as well as CAPITAL GAINS realized
by the fund on the sale of its investment securities.

   [GRAPHIC OF TRIANGLE]

   CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS,
   SUCH AS STOCK, FROM THE TIME THE ASSETS ARE PURCHASED.

The fund generally pays distributions from net income and capital gains, if any,
once a year in December. It may make more frequent distributions, if necessary,
to comply with Internal Revenue Code provisions.

You will participate in fund distributions when they are declared, starting the
next business day after your purchase is effective. For example, if you purchase
shares on a day that a distribution is declared, you will not receive that
distribution. If you redeem shares, you will receive any distribution declared
on the day you redeem. If you redeem all shares, we will include any
distributions received with your redemption proceeds.

Participants in tax-deferred retirement plans must reinvest all distributions.
For investors investing through taxable accounts, we will reinvest distributions
unless you elect to have dividends and/or capital gains sent to another American
Century account, to your bank electronically, or to your home address or to
another person or address by check.


------
26


TAXES

The tax consequences of owning shares of the fund will vary depending on whether
you own them through a taxable or tax-deferred account. Tax consequences result
from distributions by the fund of dividend and interest income it has received
or capital gains it has generated through its investment activities. Tax
consequences also may result when investors sell fund shares after the net asset
value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred account, such as an IRA or
employer-sponsored retirement plan, income and capital gains distributions
usually will not be subject to current taxation but will accumulate in your
account under the plan on a tax-deferred basis. Likewise, moving from one fund
to another fund within a plan or tax-deferred account generally will not cause
you to be taxed. For information about the tax consequences of making purchases
or withdrawals through a tax-deferred account, please consult your plan
administrator, your summary plan description or a tax advisor.

Taxable Accounts

If you own fund shares through a taxable account, you may be taxed on your
investments if the fund makes distributions or if you sell your fund shares.




Taxability of Distributions

Fund distributions may consist of income, such as dividends and interest earned
by the fund from its investments, or capital gains generated by the fund from
the sale of investment securities. Distributions of income are taxed as ordinary
income, unless they are designated as QUALIFIED DIVIDEND INCOME and you meet a
minimum required holding period with respect to your shares of the fund, in
which case distributions of income are taxed as long-term capital gains.

   [GRAPHIC OF TRIANGLE]



   QUALIFIED DIVIDEND INCOME IS A DIVIDEND RECEIVED BY A FUND FROM THE
   STOCK OF A DOMESTIC OR QUALIFYING FOREIGN CORPORATION, PROVIDED THAT THE
   FUND HAS HELD THE STOCK FOR A REQUIRED HOLDING PERIOD.

For capital gains and for income distributions designated as qualified dividend
income, the following rates apply:

                                       TAX RATE FOR 10%      TAX RATE FOR
TYPE OF DISTRIBUTION                   AND 15% BRACKETS      ALL OTHER BRACKETS
--------------------------------------------------------------------------------
Short-term capital gains               Ordinary Income       Ordinary Income
--------------------------------------------------------------------------------
Long-term capital gains (1 year)
and Qualified Dividend Income          5%                    15%
--------------------------------------------------------------------------------


If the fund's distributions exceed its taxable income and capital gains realized
during the tax year, all or a portion of the distributions made by the fund in
that tax year will be considered a return of capital. A return of capital
distribution is generally not subject to tax, but will reduce your cost basis in
the fund and result in higher realized capital gains (or lower realized capital
losses) upon the sale of fund shares.


------
27


The tax status of any distributions of capital gains is determined by how long
the fund held the underlying security that was sold, not by how long you have
been invested in the fund, or whether you reinvest your distributions in
additional shares or take them in cash. For taxable accounts, American Century
or your financial intermediary will inform you of the tax status of fund
distributions for each calendar year in an annual tax mailing.

Distributions also may be subject to state and local taxes. Because everyone's
tax situation is unique, you may want to consult your tax professional about
federal, state and local tax consequences.

Taxes on Transactions

Your redemptions - including exchanges to other American Century funds - are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. If a loss is realized on the
redemption of fund shares, the reinvestment in additional fund shares within 30
days before or after the redemption may be subject to the wash sale rules of the
Internal Revenue Code. This may result in a postponement of the recognition of
such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to withholding, we
are required to withhold and pay to the IRS the applicable federal withholding
tax rate on taxable dividends, capital gains distributions and redemption
proceeds.

Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that the fund's portfolio may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. The fund distributes those gains to you, after subtracting any losses,
even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.


------
28


MULTIPLE CLASS INFORMATION


American Century offers the following classes of shares of the fund: Investor
Class, Institutional Class, A Class, B Class, C Class and R Class.

The classes have different fees, expenses and/or minimum investment
requirements. The difference in the fee structures between the classes is the
result of their separate arrangements for shareholder and distribution services.
It is not the result of any difference in advisory or custodial fees or other
expenses related to the management of the fund's assets, which do not vary by
class. The Institutional Class is made available to institutional shareholders
or through financial intermediaries whose clients do not require the same level
of shareholder and administrative services from the advisor as shareholders of
the other classes. As a result, the advisor is able to charge this class a lower
unified management fee. Different fees and expenses will affect performance.

Except as described below, all classes of shares of the fund have identical
voting, dividend, liquidation and other rights, preferences, terms and
conditions. The only differences among the classes are (a) each class may be
subject to different expenses specific to that class; (b) each class has a
different identifying designation or name; (c) each class has exclusive voting
rights with respect to matters solely affecting such class; (d) each class may
have different exchange privileges; (e) the Institutional Class may provide for
automatic conversion from that class into shares of the Investor Class of the
same fund; and (f) the B Class provides for automatic conversion from that class
into shares of the A Class of the same fund after eight years.




Service, Distribution and Administrative Fees

Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay certain expenses associated with the distribution of their shares out of
fund assets. Each class, except the Investor Class and Institutional Class,
offered by this prospectus has a 12b-1 plan. The plans provide for the fund to
pay annual fees of 0.25% for A Class, 1.00% for B and C Classes, and 0.50% for R
Class to the distributor for distribution and individual shareholder services,
including past distribution services. The distributor pays all or a portion of
such fees to the financial intermediaries that make the classes available.
Because these fees may be used to pay for services that are not related to
prospective sales of the fund, each class will continue to make payments under
its plan even if it is closed to new investors. Because these fees are paid out
of the fund's assets on an ongoing basis, over time these fees will increase the
cost of your investment and may cost you more than paying other types of sales
charges. The higher fees for B and C Class shares may cost you more over time
than paying the initial sales charge for A Class shares. For additional
information about the plans and their terms, see MULTIPLE CLASS STRUCTURE in the
statement of additional information.

Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, the advisor will pay such
service providers a fee for performing those services. Also, the advisor and the
fund's distributor may make payments to intermediaries for various additional
services, other expenses and/or the intermediaries' distribution of the fund out
of their profits or other available sources. Such payments may be made for one
or more of the following: (1) distribution, which may include expenses incurred
by intermediaries for their sales activities with respect to the fund, such as
preparing, printing and distributing sales literature and advertising materials
and compensating registered representatives or other employees of such financial
intermediaries for their sales activities, as well as the opportunity for the
fund to be made available by such intermediaries; (2) shareholder services, such
as providing individual and custom investment advisory services to clients of
the financial intermediaries; and (3) marketing and promotional services,
including business planning assistance, educating personnel about the fund, and
sponsorship of sales meetings, which may include covering costs of providing
speakers, meals and other entertainment. The distributor may sponsor seminars
and conferences designed to educate intermediaries about the fund and may cover
the expenses associated with attendance at such meetings, including travel
costs. These payments and activities are intended to provide an incentive to
intermediaries to sell the fund by educating them about the fund and helping
defray the costs associated with offering the fund. The amount of any payments
described by this paragraph is determined by the advisor or the distributor, and
all such amounts are paid out of the available assets of the advisor and
distributor, and not by you or the fund. As a result, the total expense ratio of
the fund will not be affected by any such payments.

On July 2, 1990, the company reorganized as a Maryland corporation, and in January 1997 it changed its name to American Century Mutual Funds, Inc. Throughout this statement of additional information we refer to American Century Mutual Funds, Inc. as the corporation. For accounting and performance purposes, the Mid Cap Growth Fund is the post-reorganization successor to the Mason Street Aggressive Growth Stock Fund, and the Small Cap Growth Fund is the post-reorganization successor to the Mason Street Small Cap Growth Stock Fund.

Each fund described in this statement of additional information is a separate series of the corporation and operates for many purposes as if it were an independent company. Each fund has its own investment objective, strategy, management team, assets, and tax identification and stock registration numbers.

Management, Inc., can use various investment vehicles and strategies in managing each fund's assets. Descriptions of the investment techniques and risks associated with each appear in the section, INVESTMENT STRATEGIES AND RISKS, which begins on page 6. In the case of the funds' principal investment strategies, these descriptions elaborate upon discussions contained in the prospectuses. Each fund, other than Veedot, is diversified as defined in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total assets, each fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10% of the outstanding voting securities of a single issuer (other than U.S. government securities and securities of other investment companies). Veedot is nondiversified. Nondiversified means that a fund may invest a greater portion of its assets in a smaller number of securities than a diversified fund. Although Veedot's portfolio managers expect that it will ordinarily satisfy the requirements of a diversified fund, its nondiversified status gives it more flexibility to invest heavily in the most attractive companies identified by the fund's methodology. To meet federal tax requirements for qualification as a regulated investment company, each fund must limit its investments so that at the close of each quarter of its taxable year (1) no more than 25% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company), and (2) with respect to at least 50% of its total assets, no more than 5% of its total assets are invested in the securities of a single issuer (other than the U.S. government or a regulated investment company) or it does not own more than 10% of the outstanding voting securities of a single issuer. CAPITAL GROWTH, FOCUSED GROWTH, FUNDAMENTAL EQUITY, GIFTRUST, GROWTH, HERITAGE, MID CAP GROWTH, NEW OPPORTUNITIES, NEW OPPORTUNITIES II, NT GROWTH, NT VISTA, SELECT, SMALL CAP GROWTH, ULTRA, VEEDOT AND VISTA In general, within the restrictions outlined here and in the funds' prospectuses, the portfolio managers have broad powers to decide how to invest fund assets, including the power to hold them uninvested. Investments are varied according to what is judged advantageous under changing economic conditions. It is the advisor's policy to retain maximum flexibility in management without restrictive provisions as to the proportion of one or another class of securities that may be held, subject to the investment restrictions described ------ 4 on the following pages. It is the advisor's intention that each fund will generally consist of domestic and foreign common stocks, convertible securities and equity-equivalent securities. However, subject to the specific limitations applicable to a fund, the funds' management teams may invest the assets of each fund in varying amounts in other instruments and may use other techniques, such as those reflected in the FUND INVESTMENTS AND RISKS section, when such a course is deemed appropriate in order to pursue a fund's investment objective. Senior securities that, in the opinion of the portfolio managers, are high-grade issues also may be purchased for defensive purposes. So long as a sufficient number of acceptable securities are available, the portfolio managers intend to keep the funds fully invested, regardless of the movement of stock or bond prices, generally. However, should a fund's investment methodology fail to identify sufficient acceptable securities, or for any other reason including the desire to take a temporary defensive position, the funds may invest their assets in money market and other short-term securities. See TEMPORARY DEFENSIVE MEASURES, page 30. With regard to Veedot, the portfolio managers intend to keep the fund fully invested so long as the methodology identifies sufficient accelerating securities whose share price patterns suggest their stock prices are likely to increase in value. In most circumstances, each fund's actual level of cash and cash equivalents will be less than 10%. The managers may use futures contracts as a way to expose each fund's cash assets to the market while maintaining liquidity. The managers may not leverage a fund's portfolio. See DERIVATIVE SECURITIES, page 9, FUTURES AND OPTIONS, page 13 and SHORT-TERM SECURITIES, page 24. BALANCED In general, within the restrictions outlined here and in the fund's prospectus, the portfolio managers have broad powers to decide how to invest fund assets, including the power to hold them uninvested. As a matter of fundamental policy, the managers will invest approximately 60% of the fund's portfolio in equity securities and the remainder in bonds and other fixed-income securities. The equity portion of the fund generally will be invested in equity securities of companies comprising the 1,500 largest publicly traded companies in the United States. The fund's investment approach may cause its equity portion to be more heavily invested in some industries than in others. However, it may not invest more than 25% of its total assets in companies whose principal business activities are in the same industry. In addition, as a diversified investment company, its investments in a single issue are limited, as described above in FUND INVESTMENT GUIDELINES. The portfolio managers also may purchase foreign securities, convertible securities, equity-equivalent securities, non-leveraged futures contracts and similar securities, and short-term securities. The fixed-income portion of the fund generally will be invested in a diversified portfolio of high- and medium- grade government, corporate, asset-backed and similar securities. There are no maturity restrictions on the fixed-income securities in which the fund invests, but under normal conditions the weighted average maturity for the fixed-income portion of the fund will be in the 3-to-10-year range. The managers will actively manage the portfolio, adjusting the portfolio's weighted average maturity in response to expected changes in interest rates. During periods of rising interest rates, or when rates are expected to rise, a shorter-weighted average maturity may be adopted in order to reduce the effect of bond price declines on the fund's net asset value. When interest rates are falling, or expected to fall, and bond prices rising, or expected to rise, a longer-weighted average portfolio maturity may be adopted. The restrictions on the quality of the fixed-income securities the fund may purchase are described in the prospectus. For a description of the fixed-income securities rating system, see EXPLANATION OF FIXED-INCOME SECURITIES RATINGS, on page 95. ------ 5 CAPITAL VALUE The portfolio managers will invest primarily in stocks of medium to large companies that the managers believe are undervalued at the time of purchase. The portfolio managers will usually purchase common stocks of U.S. and foreign companies, but they can purchase other types of securities as well, such as domestic and foreign preferred stocks, convertible securities, equity-equivalent securities, notes, bonds and other debt securities. FUND INVESTMENTS AND RISKS INVESTMENT STRATEGIES AND RISKS This section describes investment vehicles and techniques the portfolio managers can use in managing a fund's assets. It also details the risks associated with each, because each investment vehicle and technique contributes to a fund's overall risk profile. Adjustable-Rate Mortgage Loans (ARMs) ARMs eligible for inclusion in a mortgage pool generally will provide for a fixed initial mortgage interest rate for a specified period of time, generally for either the first three, six, 12, 24, 36, 60 or 84 scheduled monthly payments. Thereafter, the interest rates are subject to periodic adjustment based on changes in an index. ARMs have minimum and maximum rates beyond which the mortgage interest rate may not vary over the lifetime of the loan. Certain ARMs provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. Negatively amortizing ARMs may provide limitations on changes in the required monthly payment. Limitations on monthly payments can result in monthly payments that are greater or less than the amount necessary to amortize a negatively amortizing ARM by its maturity at the interest rate in effect during any particular month. There are two types of indices that provide the basis for ARM rate adjustments: those based on market rates and those based on a calculated measure, such as a cost-of-funds index or a moving average of mortgage rates. Commonly utilized indices include the one-year, three-year and five-year constant maturity U.S. Treasury rates (as reported by the Federal Reserve Board); the three-month Treasury bill rate; the 180-day Treasury bill rate; rates on longer-term Treasury securities; the Eleventh District Federal Home Loan Bank Cost of Funds Index (EDCOFI); the National Median Cost of Funds Index; the one-month, three-month, six-month or one-year London Interbank Offered Rate (LIBOR); or six-month CD rates. Some indices, such as the one-year constant maturity Treasury rate or three-month LIBOR, are highly correlated with changes in market interest rates. Other indices, such as the EDCOFI, tend to lag behind changes in market rates and be somewhat less volatile over short periods of time. The EDCOFI reflects the monthly weighted average cost of funds of savings and loan associations and savings banks whose home offices are located in Arizona, California and Nevada (the Federal Home Loan Bank Eleventh District) and who are member institutions of the Federal Home Loan Bank of San Francisco (the FHLB of San Francisco), as computed from statistics tabulated and published by the FHLB of San Francisco. The FHLB of San Francisco normally announces the Cost of Funds Index on the last working day of the month following the month in which the cost of funds was incurred. One-year and three-year Constant Maturity Treasury (CMT) rates are calculated by the Federal Reserve Bank of New York, based on daily closing bid yields on actively traded Treasury securities submitted by five leading broker-dealers. The median bid yields are used to construct a daily yield curve. ------ 6 The National Median Cost of Funds Index, similar to the EDCOFI, is calculated monthly by the Federal Home Loan Bank Board (FHLBB) and represents the average monthly interest expenses on liabilities of member institutions. A median, rather than an arithmetic mean, is used to reduce the effect of extreme numbers. LIBOR is the rate at which banks in London offer Eurodollars in trades between banks. LIBOR has become a key rate in the U.S. domestic money market because it is perceived to reflect the true global cost of money. The portfolio managers may invest in ARMs whose periodic interest rate adjustments are based on new indices as these indices become available. Asset-Backed Securities (ABS) ABS are structured like mortgage-backed securities, but instead of mortgage loans or interest in mortgage loans, the underlying assets may include, for example, such items as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property, home equity loans, student loans, small business loans, and receivables from credit card agreements. The ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited. The value of an ABS is affected by changes in the market's perception of the assets backing the security, the creditworthiness of the servicing agent for the loan pool, the originator of the loans, or the financial institution providing any credit enhancement. Payments of principal and interest passed through to holders of ABS are typically supported by some form of credit enhancement, such as a letter of credit, surety bond, limited guarantee by another entity or a priority to certain of the borrower's other securities. The degree of credit enhancement varies, and generally applies to only a fraction of the asset-backed security's par value until exhausted. If the credit enhancement of an ABS held by the fund has been exhausted, and if any required payments of principal and interest are not made with respect to the underlying loans, the fund may experience losses or delays in receiving payment. Some types of ABS may be less effective than other types of securities as a means of "locking in" attractive long-term interest rates. One reason is the need to reinvest prepayments of principal; another is the possibility of significant unscheduled prepayments resulting from declines in interest rates. These prepayments would have to be reinvested at lower rates. As a result, these securities may have less potential for capital appreciation during periods of declining interest rates than other securities of comparable maturities, although they may have a similar risk of decline in market value during periods of rising interest rates. Prepayments may also significantly shorten the effective maturities of these securities, especially during periods of declining interest rates. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing the volatility of the fund. The risks of investing in ABS are ultimately dependent upon the repayment of loans by the individual or corporate borrowers. Although the fund would generally have no recourse against the entity that originated the loans in the event of default by a borrower, ABS typically are structured to mitigate this risk of default. Asset-backed securities are generally issued in more than one class, each with different payment terms. Multiple class asset-backed securities may be used as a method of providing credit support through creation of one or more classes whose right to payments is made subordinate to the right to such payments of the remaining class or classes. Multiple classes also may permit the issuance of securities with payment terms, interest rates or other characteristics differing both from those of each other and from those of the underlying assets. Examples include ------ 7 so-called strips (asset-backed securities entitling the holder to disproportionate interests with respect to the allocation of interest and principal of the assets backing the security), and securities with classes having characteristics such as floating interest rates or scheduled amortization of principal. Convertible Securities A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular time period at a specified price or formula. A convertible security entitles the holder to receive the interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion or exchange, such securities ordinarily provide a stream of income with generally higher yields than common stocks of the same or similar issuers, but lower than the yield on non-convertible debt. Of course, there can be no assurance of current income because issuers of convertible securities may default on their obligations. In addition, there can be no assurance of capital appreciation because the value of the underlying common stock will fluctuate. Because of the conversion feature, the managers consider some convertible securities to be equity equivalents. The price of a convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset. A convertible security is subject to risks relating to the activities of the issuer and/or general market and economic conditions. The stream of income typically paid on a convertible security may tend to cushion the security against declines in the price of the underlying asset. However, the stream of income causes fluctuations based upon changes in interest rates and the credit quality of the issuer. In general, the value of a convertible security is a function of (1) its yield in comparison with yields of other securities of comparable maturity and quality that do not have a conversion privilege and (2) its worth, at market value, if converted or exchanged into the underlying common stock. The price of a convertible security often reflects such variations in the price of the underlying common stock in a way that a non-convertible security does not. At any given time, investment value generally depends upon such factors as the general level of interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer and the seniority of the security in the issuer's capital structure. A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by a fund is called for redemption, the fund would be required to permit the issuer to redeem the security and convert it to underlying common stock or to cash, or would sell the convertible security to a third party, which may have an adverse effect on the fund. A convertible security may feature a put option that permits the holder of the convertible security to sell that security back to the issuer at a predetermined price. A fund generally invests in convertible securities for their favorable price characteristics and total return potential and normally would not exercise an option to convert unless the security is called or conversion is forced. Debt Securities Each of the funds may invest in debt securities when the portfolio managers believe such securities represent an attractive investment for the fund. The funds may invest in debt securities for income, or as a defensive strategy when the managers believe adverse economic or market conditions exist. ------ 8 The value of debt securities in which the funds may invest will fluctuate based upon changes in interest rates and the credit quality of the issuer. Debt securities generally will be limited to investment-grade obligations. Investment-grade means that at the time of purchase, such obligations are rated within the four highest categories by a nationally recognized statistical rating organization (for example, at least Baa by Moody's Investors Service, Inc. or BBB by Standard & Poor's Corporation), or, if not rated, are of equivalent investment quality as determined by the fund's advisor. According to Moody's, bonds rated Baa are medium-grade and possess some speculative characteristics. A BBB rating by S&P indicates S&P's belief that a security exhibits a satisfactory degree of safety and capacity for repayment, but is more vulnerable to adverse economic conditions and changing circumstances. Balanced may invest up to 15% in securities rated in the fifth category. Mid Cap Growth and Small Cap Growth will not invest more than 10% of their assets in high-yield, high-risk bonds. A high-yield security is one that has been rated below the four highest categories used by a nationally recognized statistical rating organization, or determined by the investment advisor to be of similar quality. Issuers of these securities often have short financial histories or questionable credit. High-yield bonds are regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and interest payments. In addition, the value of a fund's investments in fixed-income securities will change as prevailing interest rates change. In general, the prices of such securities vary inversely with interest rates. As prevailing interest rates fall, the prices of bonds and other securities that trade on a yield basis generally rise. When prevailing interest rates rise, bond prices generally fall. Depending upon the particular amount and type of fixed-income securities holdings of a fund, these changes may impact the net asset value of that fund's shares. Derivative Securities To the extent permitted by its investment objectives and policies, each of the funds may invest in securities that are commonly referred to as derivative securities. Generally, a derivative security is a financial arrangement the value of which is based on, or derived from, a traditional security, asset, or market index. Certain derivative securities are described more accurately as index/structured securities. Index/structured securities are derivative securities whose value or performance is linked to other equity securities (such as depositary receipts), currencies, interest rates, indices or other financial indicators (reference indices). Some derivative securities, such as mortgage-related and other asset-backed securities, are in many respects like any other investment, although they may be more volatile or less liquid than more traditional debt securities. There are many different types of derivative securities and many different ways to use them. Futures and options are commonly used for traditional hedging purposes to attempt to protect a fund from exposure to changing interest rates, securities prices, or currency exchange rates and for cash management purposes as a low-cost method of gaining exposure to a particular securities market without investing directly in those securities. No fund may invest in a derivative security unless the reference index or the instrument to which it relates is an eligible investment for the fund. For example, a security whose underlying value is linked to the price of oil would not be a permissible investment because the funds may not invest in oil and gas leases or futures. ------ 9 The return on a derivative security may increase or decrease, depending upon changes in the reference index or instrument to which it relates. There are risks associated with investing in derivative securities, including: * the risk that the underlying security, interest rate, market index or other financial asset will not move in the direction the portfolio managers anticipate; * the possibility that there may be no liquid secondary market, or the possibility that price fluctuation limits may be imposed by the exchange, either of which may make it difficult or impossible to close out a position when desired; * the risk that adverse price movements in an instrument can result in a loss substantially greater than a fund's initial investment; and * the risk that the counterparty will fail to perform its obligations. The funds' Board of Directors has reviewed the advisor's policy regarding investments in derivative securities. That policy specifies factors that must be considered in connection with a purchase of derivative securities and provides that a fund may not invest in a derivative security if it would be possible for a fund to lose more money than the notional value of the investment. The policy also establishes a committee that must review certain proposed purchases before the purchases can be made. The advisor will report on fund activity in derivative securities to the Board of Directors as necessary. Equity Equivalents In addition to investing in common stocks, the funds may invest in other equity securities and equity equivalents, including securities that permit a fund to receive an equity interest in an issuer, the opportunity to acquire an equity interest in an issuer, or the opportunity to receive a return on its investment that permits the fund to benefit from the growth over time in the equity of an issuer. Examples of equity securities and equity equivalents include preferred stock, convertible preferred stock and convertible securities. Equity equivalents also may include securities whose value or return is derived from the value or return of a different security. Foreign Securities Mid Cap Growth Fund and Small Cap Growth Fund may invest up to 20% of their assets in equity securities of foreign issuers. The other funds may invest an unlimited portion of their assets in the securities of issuers located in foreign countries, including foreign governments, when these securities meet its standards of selection. In determining where a company is located, the portfolio managers will consider various factors, including where the company is headquartered, where the company's principal operations are located, where the company's revenues are derived, where the principal trading market is located and the country in which the company was legally organized. The weight given to each of these factors will vary depending on the circumstances in a given case. The funds consider developed countries to include Australia, Austria, Belgium, Bermuda, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Italy, Japan, Luxembourg, The Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. Securities of foreign issuers may trade in the U.S. or foreign securities markets. Investments in foreign securities may present certain risks, including: CURRENCY RISK - The value of the foreign investments held by the funds may be significantly affected by changes in currency exchange rates. The dollar value of a foreign security generally decreases when the value of the dollar rises against the foreign currency in which the security is denominated and tends to increase when the value of the dollar falls against such currency. In addition, the value of fund assets may be affected by losses and other expenses incurred in converting ------ 10 between various currencies in order to purchase and sell foreign securities, and by currency restrictions, exchange control regulation, currency devaluations and political developments. POLITICAL AND ECONOMIC RISK - The economies of many of the countries in which the funds invest are not as developed as the economy of the United States and may be subject to significantly different forces. Political or social instability, expropriation, nationalization, confiscatory taxation and limitations on the removal of funds or other assets also could adversely affect the value of investments. Further, the funds may find it difficult or be unable to enforce ownership rights, pursue legal remedies or obtain judgments in foreign courts. REGULATORY RISK - Foreign companies generally are not subject to the regulatory controls imposed on U.S. issuers and, in general, there is less publicly available information about foreign securities than is available about domestic securities. Many foreign companies are not subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies. Income from foreign securities owned by the funds may be reduced by a withholding tax at the source, which would reduce dividend income payable to shareholders. MARKET AND TRADING RISK - Brokerage commission rates in foreign countries, which generally are fixed rather than subject to negotiation as in the United States, are likely to be higher. The securities markets in many of the countries in which the funds invest will have substantially less trading volume than the principal U.S. markets. As a result, the securities of some companies in these countries may be less liquid and more volatile than comparable U.S. securities. Furthermore, one securities broker may represent all or a significant part of the trading volume in a particular country, resulting in higher trading costs and decreased liquidity due to a lack of alternative trading partners. There generally is less government regulation and supervision of foreign stock exchanges, brokers and issuers, which may make it difficult to enforce contractual obligations. CLEARANCE AND SETTLEMENT RISK - Foreign securities markets also have different clearance and settlement procedures, and in certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. Delays in clearance and settlement could result in temporary periods when assets of the funds are uninvested and no return is earned. The inability of the funds to make intended security purchases due to clearance and settlement problems could cause the funds to miss attractive investment opportunities. Inability to dispose of portfolio securities due to clearance and settlement problems could result either in losses to the funds due to subsequent declines in the value of the portfolio security or, if the fund has entered into a contract to sell the security, liability to the purchaser. OWNERSHIP RISK - Evidence of securities ownership may be uncertain in many foreign countries. As a result, there is a risk that a fund's trade details could be incorrectly or fraudulently entered at the time of the transaction, resulting in a loss to the fund. EMERGING MARKETS RISK - Each fund may invest its holdings in securities of issuers located in emerging market (developing) countries. The funds consider "emerging market countries" to include all countries that are not considered by the advisor to be developed countries, which are listed in page 10. Investing in securities of issuers in emerging market countries involves exposure to significantly higher risk than investing in countries with developed markets. Emerging market countries may have economic structures that generally are less diverse and mature, and political systems that can be expected to be less stable than those of developed countries. Securities prices in emerging market countries can be significantly more volatile than in developed countries, reflecting the greater uncertainties of investing in lesser developed markets and economies. In ------ 11 particular, emerging market countries may have relatively unstable governments, and may present the risk of nationalization of businesses, expropriation, confiscatory taxation or in certain instances, reversion to closed-market, centrally planned economies. Such countries may also have less protection of property rights than developed countries. The economies of emerging market countries may be based predominantly on only a few industries or may be dependent on revenues from particular commodities or on international aid or developmental assistance, may be highly vulnerable to changes in local or global trade conditions, and may suffer from extreme and volatile debt burdens or inflation rates. In addition, securities markets in emerging market countries may trade a relatively small number of securities and may be unable to respond effectively to increases in trading volume, potentially resulting in a lack of liquidity and in volatility in the price of securities traded on those markets. Also, securities markets in emerging market countries typically offer less regulatory protection for investors. Forward Currency Exchange Contracts Each fund may purchase and sell foreign currency on a spot (i.e., cash) basis and may engage in forward currency contracts, currency options and futures transactions for hedging or any other lawful purpose. See DERIVATIVE SECURITIES, page 9. The funds expect to use forward currency contracts under two circumstances: (1) When the portfolio managers are purchasing or selling a security denominated in a foreign currency and wish to lock in the U.S. dollar price of that security, the portfolio managers would be able to enter into a forward currency contract to do so; (2) When the portfolio managers believe that the currency of a particular foreign country may suffer a substantial decline against the U.S. dollar, a fund would be able to enter into a forward currency contract to sell foreign currency for a fixed U.S. dollar amount approximating the value of some or all of its portfolio securities either denominated in, or whose value is tied to, such foreign currency. In the first circumstance, when a fund enters into a trade for the purchase or sale of a security denominated in a foreign currency, it may be desirable to establish (lock in) the U.S. dollar cost or proceeds. By entering into forward currency contracts in U.S. dollars for the purchase or sale of a foreign currency involved in an underlying security transaction, the fund will be able to protect itself against a possible loss between trade and settlement dates resulting from the adverse change in the relationship between the U.S. dollar and the subject foreign currency. In the second circumstance, when the portfolio managers believe that the currency of a particular country may suffer a substantial decline relative to the U.S. dollar, a fund could enter into a forward currency contract to sell for a fixed dollar amount the amount in foreign currencies approximating the value of some or all of its portfolio securities either denominated in, or whose value is tied to, such foreign currency. The fund will generally cover outstanding forward contracts by maintaining liquid portfolio securities denominated in, or whose value is tied to, the currency underlying the forward contract or the currency being hedged. To the extent that the fund is not able to cover its forward currency positions with underlying portfolio securities, the fund will segregate on its records cash or other liquid assets having a value equal to the aggregate amount of the fund's commitments under the forward currency contact. The precise matching of forward currency contracts in the amounts and values of securities involved generally would not be possible because the future values of such foreign currencies will change as a consequence of market movements in the values of those securities between the date the forward currency contract is entered into and the date it matures. Predicting short-term currency market movements is extremely difficult, and the successful execution of short-term hedging strategy is highly uncertain. Normally, consideration of the prospect for currency parities ------ 12 will be incorporated into the long-term investment decisions made with respect to overall diversification strategies. However, the portfolio managers believe that it is important to have flexibility to enter into such forward currency contracts when they determine that a fund's best interests may be served. When the forward currency contract matures, the fund may either sell the portfolio security and make delivery of the foreign currency, or it may retain the security and terminate the obligation to deliver the foreign currency by purchasing an offsetting forward currency contract with the same currency trader that obligates the fund to purchase, on the same maturity date, the same amount of the foreign currency. It is impossible to forecast with absolute precision the market value of portfolio securities at the expiration of the forward currency contract. Accordingly, it may be necessary for a fund to purchase additional foreign currency on the spot market (and bear the expense of such purchase) if the market value of the security is less than the amount of foreign currency the fund is obligated to deliver and if a decision is made to sell the security to make delivery of the foreign currency the fund is obligated to deliver. Futures and Options Each fund may enter into futures contracts, options or options on futures contracts. Futures contracts provide for the sale by one party and purchase by another party of a specific security at a specified future time and price. Generally, futures transactions will be used to: * protect against a decline in market value of the fund's securities (taking a short futures position), * protect against the risk of an increase in market value for securities in which the fund generally invests at a time when the fund is not fully invested (taking a long futures position), or * provide a temporary substitute for the purchase of an individual security that may not be purchased in an orderly fashion. Some futures and options strategies, such as selling futures, buying puts and writing calls, hedge a fund's investments against price fluctuations. Other strategies, such as buying futures, writing puts and buying calls, tend to increase market exposure. Although other techniques may be used to control a fund's exposure to market fluctuations, the use of futures contracts may be a more effective means of hedging this exposure. While a fund pays brokerage commissions in connection with opening and closing out futures positions, these costs are lower than the transaction costs incurred in the purchase and sale of the underlying securities. For example, the sale of a future by a fund means the fund becomes obligated to deliver the security (or securities, in the case of an index future) at a specified price on a specified date. The purchase of a future means the fund becomes obligated to buy the security (or securities) at a specified price on a specified date. The portfolio managers may engage in futures and options transactions based on securities indices, provided that the transactions are consistent with the fund's investment objectives. Examples of indices that may be used include the Bond Buyer Index of Municipal Bonds for fixed-income funds, or the S&P 500® Index for equity funds. The managers also may engage in futures and options transactions based on specific securities, such as U.S. Treasury bonds or notes. Futures contracts are traded on national futures exchanges. Futures exchanges and trading are regulated under the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S. government agency. Index futures contracts differ from traditional futures contracts in that when delivery takes place, no stocks or bonds change hands. Instead, these contracts settle in cash at the spot market value of the index. Although other types of futures contracts by their terms call for actual delivery or acceptance of the underlying ------ 13 securities, in most cases the contracts are closed out before the settlement date. A futures position may be closed by taking an opposite position in an identical contract (i.e., buying a contract that has previously been sold or selling a contract that has previously been bought). Unlike when the fund purchases or sells a security, no price is paid or received by the fund upon the purchase or sale of the future. Initially, the fund will be required to deposit an amount of cash or securities equal to a varying specified percentage of the contract amount. This amount is known as initial margin. The margin deposit is intended to ensure completion of the contract (delivery or acceptance of the underlying security) if it is not terminated prior to the specified delivery date. A margin deposit does not constitute a margin transaction for purposes of the fund's investment restrictions. Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, brokers may establish margin deposit requirements that are higher than the exchange minimums. Cash held in the margin accounts generally is not income-producing. However, coupon bearing securities, such as Treasury bills and bonds, held in margin accounts generally will earn income. Subsequent payments to and from the broker, called variation margin, will be made on a daily basis as the price of the underlying security or index fluctuates, making the future more or less valuable, a process known as marking the contract to market. Changes in variation margin are recorded by the fund as unrealized gains or losses. At any time prior to expiration of the future, the fund may elect to close the position by taking an opposite position. A final determination of variation margin is then made; additional cash is required to be paid by or released to the fund and the fund realizes a loss or gain. Risks Related to Futures and Options Transactions Futures and options prices can be volatile, and trading in these markets involves certain risks. If the portfolio managers apply a hedge at an inappropriate time or judge interest rate or equity market trends incorrectly, futures and options strategies may lower a fund's return. A fund could suffer losses if it is unable to close out its position because of an illiquid secondary market. Futures contracts may be closed out only on an exchange that provides a secondary market for these contracts, and there is no assurance that a liquid secondary market will exist for any particular futures contract at any particular time. Consequently, it may not be possible to close a futures position when the portfolio managers consider it appropriate or desirable to do so. In the event of adverse price movements, a fund would be required to continue making daily cash payments to maintain its required margin. If the fund had insufficient cash, it might have to sell portfolio securities to meet daily margin requirements at a time when the portfolio managers would not otherwise elect to do so. In addition, a fund may be required to deliver or take delivery of instruments underlying futures contracts it holds. The portfolio managers will seek to minimize these risks by limiting the futures contracts entered into on behalf of the funds to those traded on national futures exchanges and for which there appears to be a liquid secondary market. A fund could suffer losses if the prices of its futures and options positions were poorly correlated with its other investments, or if securities underlying futures contracts purchased by a fund had different maturities than those of the portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which a fund loses money on a futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. A fund also could lose margin payments it has deposited with a margin broker, if, for example, the broker became bankrupt. ------ 14 Most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day's settlement price at the end of the trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond the limit. However, the daily limit governs only price movement during a particular trading day and, therefore, does not limit potential losses. In addition, the daily limit may prevent liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses. Options on Futures By purchasing an option on a futures contract, a fund obtains the right, but not the obligation, to sell the futures contract (a put option) or to buy the contract (a call option) at a fixed strike price. A fund can terminate its position in a put option by allowing it to expire or by exercising the option. If the option is exercised, the fund completes the sale of the underlying security at the strike price. Purchasing an option on a futures contract does not require a fund to make margin payments unless the option is exercised. Although they do not currently intend to do so, the funds may write (or sell) call options that obligate them to sell (or deliver) the option's underlying instrument upon exercise of the option. While the receipt of option premiums would mitigate the effects of price declines, the funds would give up some ability to participate in a price increase on the underlying security. If a fund were to engage in options transactions, it would own the futures contract at the time a call were written and would keep the contract open until the obligation to deliver it pursuant to the call expired. Restrictions on the Use of Futures Contracts and Options Each fund may enter into futures contracts, options or options on futures contracts as permitted under the Commodity Futures Trading Commission rules. The funds have claimed exclusion from the definition of the term "commodity pool operator" under the Commodity Exchange Act and, therefore, are not subject to registration or regulation as commodity pool operators under that Act. To the extent required by law, each fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to cover its obligations under the futures contracts and options. Initial Public Offerings The funds may invest in initial public offerings (IPOs) of common stock or other equity securities issued by a company. The purchase of securities in an IPO may involve higher transaction costs than those associated with the purchase of securities already traded on exchanges or other established markets. In addition to the risks associated with equity securities generally, IPO securities may be subject to additional risk due to factors such as the absence of a prior public market, unseasoned trading and speculation, a potentially small number of securities available for trading, limited information about the issuer and other factors. These factors may cause IPO shares to be volatile in price. While a fund may hold IPO securities for a period of time, it may sell them in the aftermarket soon after the purchase, which could increase portfolio turnover and lead to increased expenses such as commissions and transaction costs. Investments in IPOs could have a magnified impact (either positive or negative) on performance if a fund's assets are relatively small. The impact of IPOs on a fund's performance may tend to diminish as assets grow. ------ 15 Inverse Floaters The funds may hold inverse floaters. An inverse floater is a type of derivative security that bears an interest rate that moves inversely to market interest rates. As market interest rates rise, the interest rate on inverse floaters goes down, and vice versa. Generally, this is accomplished by expressing the interest rate on the inverse floater as an above-market fixed rate of interest, reduced by an amount determined by reference to a market-based or bond-specific floating interest rate (as well as by any fees associated with administering the inverse floater program). Inverse floaters may be issued in conjunction with an equal amount of Dutch Auction floating-rate bonds (floaters), or a market-based index may be used to set the interest rate on these securities. A Dutch Auction is an auction system in which the price of the security is gradually lowered until it meets a responsive bid and is sold. Floaters and inverse floaters may be brought to market by (1) a broker-dealer who purchases fixed-rate bonds and places them in a trust, or (2) an issuer seeking to reduce interest expenses by using a floater/inverse floater structure in lieu of fixed-rate bonds. In the case of a broker-dealer structured offering (where underlying fixed-rate bonds have been placed in a trust), distributions from the underlying bonds are allocated to floater and inverse floater holders in the following manner: (i) Floater holders receive interest based on rates set at a six-month interval or at a Dutch Auction, which is typically held every 28 to 35 days. Current and prospective floater holders bid the minimum interest rate that they are willing to accept on the floaters, and the interest rate is set just high enough to ensure that all of the floaters are sold. (ii) Inverse floater holders receive all of the interest that remains, if any, on the underlying bonds after floater interest and auction fees are paid. The interest rates on inverse floaters may be significantly reduced, even to zero, if interest rates rise. Procedures for determining the interest payment on floaters and inverse floaters brought to market directly by the issuer are comparable, although the interest paid on the inverse floaters is based on a presumed coupon rate that would have been required to bring fixed-rate bonds to market at the time the floaters and inverse floaters were issued. Where inverse floaters are issued in conjunction with floaters, inverse floater holders may be given the right to acquire the underlying security (or to create a fixed-rate bond) by calling an equal amount of corresponding floaters. The underlying security may then be held or sold. However, typically, there are time constraints and other limitations associated with any right to combine interests and claim the underlying security. Floater holders subject to a Dutch Auction procedure generally do not have the right to put back their interests to the issuer or to a third party. If a Dutch Auction fails, the floater holder may be required to hold its position until the underlying bond matures, during which time interest on the floater is capped at a predetermined rate. The secondary market for floaters and inverse floaters may be limited. The market value of inverse floaters tends to be significantly more volatile than fixed-rate bonds. Investment in Issuers with Limited Operating Histories The funds may invest the following portions of their assets in the equity securities of issuers with limited operating histories: Balanced, Capital Growth, Focused Growth, Fundamental Equity, Growth, NT Growth, Select and Ultra up to 5%; Giftrust, Heritage, Mid Cap Growth, New Opportunities, New Opportunities II, ------ 16 NT Vista, Small Cap Growth, Veedot and Vista up to 10%. Capital Value may invest an unlimited portion of its equity securities in issuers with limited operating histories. The managers consider an issuer to have a limited operating history if that issuer has a record of less than three years of continuous operation. The managers will consider periods of capital formation, incubation, consolidations, and research and development in determining whether a particular issuer has a record of three years of continuous operation. Investments in securities of issuers with limited operating histories may involve greater risks than investments in securities of more mature issuers. By their nature, such issuers present limited operating histories and financial information upon which the managers may base their investment decision on behalf of the funds. In addition, financial and other information regarding such issuers, when available, may be incomplete or inaccurate. For purposes of this limitation, "issuers" refers to operating companies that issue securities for the purposes of issuing debt or raising capital as a means of financing their ongoing operations. It does not, however, refer to entities, corporate or otherwise, that are created for the express purpose of securitizing obligations or income streams. For example, a fund's investments in a trust created for the purpose of pooling mortgage obligations would not be subject to the limitation. Mortgage-Backed Securities Background A mortgage-backed security represents an ownership interest in a pool of mortgage loans. The loans are made by financial institutions to finance home and other real estate purchases. As the loans are repaid, investors receive payments of both interest and principal. Like fixed-income securities such as U.S. Treasury bonds, mortgage-backed securities pay a stated rate of interest during the life of the security. However, unlike a bond, which returns principal to the investor in one lump sum at maturity, mortgage-backed securities return principal to the investor in increments during the life of the security. Because the timing and speed of principal repayments vary, the cash flow on mortgage-backed securities is irregular. If mortgage holders sell their homes, refinance their loans, prepay their mortgages or default on their loans, the principal is distributed pro rata to investors. As with other fixed-income securities, the prices of mortgage-backed securities fluctuate in response to changing interest rates; when interest rates fall, the prices of mortgage-backed securities rise, and vice versa. Changing interest rates have additional significance for mortgage-backed securities investors, however, because they influence prepayment rates (the rates at which mortgage holders prepay their mortgages), which in turn affect the yields on mortgage-backed securities. When interest rates decline, prepayment rates generally increase. Mortgage holders take advantage of the opportunity to refinance their mortgages at lower rates with lower monthly payments. When interest rates rise, mortgage holders are less inclined to refinance their mortgages. The effect of prepayment activity on yield depends on whether the mortgage-backed security was purchased at a premium or at a discount. A fund may receive principal sooner than it expected because of accelerated prepayments. Under these circumstances, the fund might have to reinvest returned principal at rates lower than it would have earned if principal payments were made on schedule. Conversely, a mortgage-backed security may exceed its anticipated life if prepayment rates decelerate unexpectedly. Under these circumstances, a fund might miss an opportunity to earn interest at higher prevailing rates. ------ 17 GNMA Certificates The Government National Mortgage Association (GNMA) is a wholly owned corporate instrumentality of the United States within the Department of Housing and Urban Development. The National Housing Act of 1934 (Housing Act), as amended, authorizes GNMA to guarantee the timely payment of interest and repayment of principal on certificates that are backed by a pool of mortgage loans insured by the Federal Housing Administration under the Housing Act, or by Title V of the Housing Act of 1949 (FHA Loans), or guaranteed by the Department of Veterans Affairs under the Servicemen's Readjustment Act of 1944 (VA Loans), as amended, or by pools of other eligible mortgage loans. The Housing Act provides that the full faith and credit of the U.S. government is pledged to the payment of all amounts that may be required to be paid under any guarantee. GNMA has unlimited authority to borrow from the U.S. Treasury in order to meet its obligations under this guarantee. GNMA certificates represent a pro rata interest in one or more pools of the following types of mortgage loans: (a) fixed-rate level payment mortgage loans; (b) fixed-rate graduated payment mortgage loans (GPMs); (c) fixed-rate growing equity mortgage loans (GEMs); (d) fixed-rate mortgage loans secured by manufactured (mobile) homes (MHs); (e) mortgage loans on multifamily residential properties under construction (CLCs); (f) mortgage loans on completed multifamily projects (PLCs); (g) fixed-rate mortgage loans that use escrowed funds to reduce the borrower's monthly payments during the early years of the mortgage loans (buydown mortgage loans); and (h) mortgage loans that provide for payment adjustments based on periodic changes in interest rates or in other payment terms of the mortgage loans. Fannie Mae Certificates The Federal National Mortgage Association (FNMA or Fannie Mae) is a federally chartered and privately owned corporation established under the Federal National Mortgage Association Charter Act. Fannie Mae was originally established in 1938 as a U.S. government agency designed to provide supplemental liquidity to the mortgage market and was reorganized as a stockholder-owned and privately managed corporation by legislation enacted in 1968. Fannie Mae acquires capital from investors who would not ordinarily invest in mortgage loans directly and thereby expands the total amount of funds available for housing. This money is used to buy home mortgage loans from local lenders, replenishing the supply of capital available for mortgage lending. Fannie Mae certificates represent a pro rata interest in one or more pools of FHA Loans, VA Loans, or, most commonly, conventional mortgage loans (i.e., mortgage loans that are not insured or guaranteed by a government agency) of the following types: (a) fixed-rate level payment mortgage loans; (b) fixed-rate growing equity mortgage loans; (c) fixed-rate graduated payment mortgage loans; (d) adjustable-rate mortgage loans; and (e) fixed-rate mortgage loans secured by multifamily projects. Fannie Mae certificates entitle the registered holder to receive amounts representing a pro rata interest in scheduled principal and interest payments (at the certificate's pass-through rate, which is net of any servicing and guarantee fees on the underlying mortgage loans), any principal prepayments, and a proportionate interest in the full principal amount of any foreclosed or otherwise liquidated mortgage loan. The full and timely payment of interest and repayment of principal on each Fannie Mae certificate is guaranteed by Fannie Mae; this guarantee is not backed by the full faith and credit of the U.S. government. ------ 18 Freddie Mac Certificates The Federal Home Loan Mortgage Corporation (FHLMC or Freddie Mac) is a corporate instrumentality of the United States created pursuant to the Emergency Home Finance Act of 1970 (FHLMC Act), as amended. Freddie Mac was established primarily for the purpose of increasing the availability of mortgage credit. Its principal activity consists of purchasing first-lien conventional residential mortgage loans (and participation interests in such mortgage loans) and reselling these loans in the form of mortgage-backed securities, primarily Freddie Mac certificates. Freddie Mac certificates represent a pro rata interest in a group of mortgage loans (a Freddie Mac certificate group) purchased by Freddie Mac. The mortgage loans underlying Freddie Mac certificates consist of fixed- or adjustable-rate mortgage loans with original terms to maturity of between 10 and 30 years, substantially all of which are secured by first-liens on one- to four-family residential properties or multifamily projects. Each mortgage loan must meet standards set forth in the FHLMC Act. A Freddie Mac certificate group may include whole loans, participation interests in whole loans, undivided interests in whole loans, and participations composing another Freddie Mac certificate group. Freddie Mac guarantees to each registered holder of a Freddie Mac certificate the timely payment of interest at the rate provided for by the certificate. Freddie Mac also guarantees ultimate collection of all principal on the related mortgage loans, without any offset or deduction, but generally does not guarantee the timely repayment of principal. Freddie Mac may remit principal at any time after default on an underlying mortgage loan, but no later than 30 days following (a) foreclosure sale, (b) payment of a claim by any mortgage insurer, or (c) the expiration of any right of redemption, whichever occurs later, and in any event no later than one year after demand has been made upon the mortgager for accelerated payment of principal. Obligations guaranteed by Freddie Mac are not backed by the full faith and credit pledge of the U.S. government. Collateralized Mortgage Obligations (CMOs) A CMO is a multiclass bond backed by a pool of mortgage pass-through certificates or mortgage loans. CMOs may be collateralized by (a) GNMA, Fannie Mae or Freddie Mac pass-through certificates; (b) unsecured mortgage loans insured by the Federal Housing Administration or guaranteed by the Department of Veterans' Affairs; (c) unsecuritized conventional mortgages; or (d) any combination thereof. In structuring a CMO, an issuer distributes cash flow from the underlying collateral over a series of classes called tranches. Each CMO is a set of two or more tranches, with average lives and cash flow patterns designed to meet specific investment objectives. The average life expectancies of the different tranches in a four-part deal, for example, might be two, five, seven and 20 years. As payments on the underlying mortgage loans are collected, the CMO issuer pays the coupon rate of interest to the bondholders in each tranche. At the outset, scheduled and unscheduled principal payments go to investors in the first tranches. Investors in later tranches do not begin receiving principal payments until the prior tranches are paid off. This basic type of CMO is known as a sequential pay or plain vanilla CMO. Some CMOs are structured so that the prepayment or market risks are transferred from one tranche to another. Prepayment stability is improved in some tranches if other tranches absorb more prepayment variability. ------ 19 The final tranche of a CMO often takes the form of a Z-bond, also known as an accrual bond or accretion bond. Holders of these securities receive no cash until the earlier tranches are paid in full. During the period that the other tranches are outstanding, periodic interest payments are added to the initial face amount of the Z-bond but are not paid to investors. When the prior tranches are retired, the Z-bond receives coupon payments on its higher principal balance plus any principal prepayments from the underlying mortgage loans. The existence of a Z-bond tranche helps stabilize cash flow patterns in the other tranches. In a changing interest rate environment, however, the value of the Z-bond tends to be more volatile. As CMOs have evolved, some classes of CMO bonds have become more prevalent. The planned amortization class (PAC) and targeted amortization class (TAC), for example, were designed to reduce prepayment risk by establishing a sinking-fund structure. PAC and TAC bonds assure to varying degrees that investors will receive payments over a predetermined period under various prepayment scenarios. Although PAC and TAC bonds are similar, PAC bonds are better able to provide stable cash flows under various prepayment scenarios than TAC bonds because of the order in which these tranches are paid. The existence of a PAC or TAC tranche can create higher levels of risk for other tranches in the CMO because the stability of the PAC or TAC tranche is achieved by creating at least one other tranche - known as a companion bond, support or non-PAC bond - that absorbs the variability of principal cash flows. Because companion bonds have a high degree of average life variability, they generally pay a higher yield. A TAC bond can have some of the prepayment variability of a companion bond if there is also a PAC bond in the CMO issue. Floating-rate CMO tranches (floaters) pay a variable rate of interest that is usually tied to the LIBOR. Institutional investors with short-term liabilities, such as commercial banks, often find floating-rate CMOs attractive investments. Super floaters (which float a certain percentage above LIBOR) and inverse floaters (which float inversely to LIBOR) are variations on the floater structure that have highly variable cash flows. Stripped Mortgage-Backed Securities Stripped mortgage-backed securities are created by segregating the cash flows from underlying mortgage loans or mortgage securities to create two or more new securities, each with a specified percentage of the underlying security's principal or interest payments. Mortgage-backed securities may be partially stripped so that each investor class receives some interest and some principal. When securities are completely stripped, however, all of the interest is distributed to holders of one type of security, known as an interest-only security, or IO, and all of the principal is distributed to holders of another type of security known as a principal-only security, or PO. Strips can be created in a pass-through structure or as tranches of a CMO. The market values of IOs and POs are very sensitive to interest rate and prepayment rate fluctuations. POs, for example, increase (or decrease) in value as interest rates decline (or rise). The price behavior of these securities also depends on whether the mortgage collateral was purchased at a premium or discount to its par value. Prepayments on discount coupon POs generally are much lower than prepayments on premium coupon POs. IOs may be used to hedge a fund's other investments because prepayments cause the value of an IO strip to move in the opposite direction from other mortgage-backed securities. Commercial Mortgage-Backed Securities (CMBS) CMBS are securities created from a pool of commercial mortgage loans, such as loans for hotels, shopping centers, office buildings, apartment buildings, and the like. Interest and principal payments from these loans are passed on to the investor according to a particular schedule of payments. They may be issued by U.S. government agencies or by private issuers. The credit quality of CMBS ------ 20 depends primarily on the quality of the underlying loans and on the structure of the particular deal. Generally, deals are structured with senior and subordinate classes. Multiple classes may permit the issuance of securities with payment terms, interest rates, or other characteristics differing both from those of each other and those of the underlying assets. Examples include classes having characteristics such as floating interest rates or scheduled amortization of principal. Rating agencies rate the individual classes of the deal based on the degree of seniority or subordination of a particular class and other factors. The value of these securities may change because of actual or perceived changes in the creditworthiness of individual borrowers, their tenants, the servicing agents, or the general state of commercial real estate and other factors. Mortgage Dollar Rolls The Balanced Fund may enter into mortgage dollar rolls in which a fund sells mortgage-backed securities to financial institutions for delivery in the current month and simultaneously contracts to repurchase similar securities on a specified future date. During the period between the sale and repurchase (the "roll period"), the fund forgoes principal and interest paid on the mortgage-backed securities. The fund is compensated by the difference between the current sales price and the lower forward price for the future purchase (often referred to as the "drop"), as well as by the interest earned on the cash proceeds of the initial sale. The fund will use the proceeds generated from the transaction to invest in high-quality, short-term investments, which may enhance the fund's current yield and total return. Such investments may have a leveraging effect, increasing the volatility of the fund. For each mortgage dollar roll transaction, a fund will cover the roll by segregating on its books an offsetting cash position or a position of liquid securities of equivalent value. The portfolio managers will monitor the value of such securities to determine that the value equals or exceeds the mortgage dollar roll contract price. A fund could suffer a loss if the contracting party fails to perform the future transaction and the fund is therefore unable to buy back the mortgage-backed securities it initially sold. The fund also takes the risk that the mortgage-backed securities that it repurchases at a later date will have less favorable market characteristics than the securities originally sold. Municipal Bonds Municipal bonds, which generally have maturities of more than one year when issued, are designed to meet longer-term capital needs. These securities have two principal classifications: general obligation bonds and revenue bonds. General Obligation (GO) bonds are issued by states, counties, cities, towns and regional districts to fund a variety of public projects, including construction of and improvements to schools, highways, and water and sewer systems. GO bonds are backed by the issuer's full faith and credit based on its ability to levy taxes for the timely payment of interest and repayment of principal, although such levies may be constitutionally or statutorily limited as to rate or amount. Revenue Bonds are not backed by an issuer's taxing authority; rather, interest and principal are secured by the net revenues from a project or facility. Revenue bonds are issued to finance a variety of capital projects, including construction or refurbishment of utility and waste disposal systems, highways, bridges, tunnels, air and seaport facilities, schools and hospitals. Many revenue bond issuers provide additional security in the form of a debt-service reserve fund that may be used to make payments of interest and repayments of principal on the issuer's obligations. Some revenue bond financings are further protected by a state's assurance (without obligation) that it will make up deficiencies in the debt-service reserve fund. ------ 21 Industrial Development Bonds (IDBs), a type of revenue bond, are issued by or on behalf of public authorities to finance privately operated facilities. These bonds are used to finance business, manufacturing, housing, athletic and pollution control projects, as well as public facilities such as mass transit systems, air and seaport facilities and parking garages. Payment of interest and repayment of principal on an IDB depend solely on the ability of the facility's operator to meet financial obligations, and on the pledge, if any, of the real or personal property financed. The interest earned on IDBs may be subject to the federal alternative minimum tax. Municipal Notes Municipal notes are issued by state and local governments or government entities to provide short-term capital or to meet cash flow needs. Tax Anticipation Notes (TANs) are issued in anticipation of seasonal tax revenues, such as ad valorem property, income, sales, use and business taxes, and are payable from these future taxes. TANs usually are general obligations of the issuer. General obligations are backed by the issuer's full faith and credit based on its ability to levy taxes for the timely payment of interest and repayment of principal, although such levies may be constitutionally or statutorily limited as to rate or amount. Revenue Anticipation Notes (RANs) are issued with the expectation that receipt of future revenues, such as federal revenue sharing or state aid payments, will be used to repay the notes. Typically, these notes also constitute general obligations of the issuer. Bond Anticipation Notes (BANs) are issued to provide interim financing until long-term financing can be arranged. In most cases, the long-term bonds provide the money for repayment of the notes. Obligations with Term Puts Attached The funds may invest in fixed-rate bonds subject to third-party puts and participation interests in such bonds that are held by a bank in trust or otherwise, which have tender options or demand features attached. These tender options or demand features permit the funds to tender (or put) their bonds to an institution at periodic intervals and to receive the principal amount thereof. The portfolio managers expect that the funds will pay more for securities with puts attached than for securities without these liquidity features. Because it is difficult to evaluate the likelihood of exercise or the potential benefit of a put, puts normally will be determined to have a value of zero, regardless of whether any direct or indirect consideration is paid. Accordingly, puts as separate securities are not expected to affect the funds' weighted average maturities. When a fund has paid for a put, the cost will be reflected as unrealized depreciation on the underlying security for the period the put is held. Any gain on the sale of the underlying security will be reduced by the cost of the put. There is a risk that the seller of an obligation with a put attached will not be able to repurchase the underlying obligation when (or if) a fund attempts to exercise the put. To minimize such risks, the funds will purchase obligations with puts attached only from sellers deemed creditworthy by the portfolio managers under the direction of the Board of Directors. Other Investment Companies Each of the funds may invest in other investment companies, such as mutual funds, provided that the investment is consistent with the fund's investment policies and restrictions. Under the Investment Company Act, a fund's investment in such securities, subject to certain exceptions, currently is limited to ------ 22 * 3% of the total voting stock of any one investment company; * 5% of the fund's total assets with respect to any one investment company; and * 10% of a fund's total assets in the aggregate. A fund's investments in other investment companies may include money market funds managed by the advisor. Investments in money market funds are not subject to the percentage limitations set forth above. Such purchases will be made in the open market where no commission or profit to a sponsor or dealer results from the purchase other than the customary brokers' commissions. As a shareholder of another investment company, a fund would bear, along with other shareholders, its pro rata portion of the other investment company's expenses, including advisory fees. These expenses would be in addition to the management fee that each fund bears directly in connection with its own operations. Each fund may invest in exchange traded funds (ETFs), such as Standard & Poor's Depositary Receipts (SPDRs) and the Lehman Aggregate Bond ETF, with the same percentage limitations as investments in registered investment companies. ETFs are a type of fund bought and sold on a securities exchange. An ETF trades like common stock and usually represents a fixed portfolio of securities designed to track the performance and dividend yield of a particular domestic or foreign market index. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although the lack of liquidity on an ETF could result in it being more volatile. Additionally, ETFs have management fees, which increase their cost. Portfolio Lending In order to realize additional income, a fund may lend its portfolio securities. Such loans may not exceed one-third of the fund's total assets valued at market except * through the purchase of debt securities in accordance with its investment objectives, policies and limitations, or * by engaging in repurchase agreements with respect to portfolio securities. Repurchase Agreements Each fund may invest in repurchase agreements when they present an attractive short-term return on cash that is not otherwise committed to the purchase of securities pursuant to the investment policies of that fund. A repurchase agreement occurs when, at the time a fund purchases an interest-bearing obligation, the seller (a bank or a broker-dealer registered under the Securities Exchange Act of 1934) agrees to purchase it on a specified date in the future at an agreed-upon price. The repurchase price reflects an agreed-upon interest rate during the time the fund's money is invested in the security. Because the security purchased constitutes collateral for the repurchase obligation, a repurchase agreement can be considered a loan collateralized by the security purchased. The fund's risk is the seller's ability to pay the agreed-upon repurchase price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral may be delayed or limited. To the extent the value of the security decreases, the fund could experience a loss. ------ 23 The funds will limit repurchase agreement transactions to securities issued by the U.S. government and its agencies and instrumentalities, and will enter into such transactions with those banks and securities dealers who are deemed creditworthy by the funds' advisor. Repurchase agreements maturing in more than seven days would count toward a fund's 15% limit on illiquid securities. Restricted and Illiquid Securities The funds may, from time to time, purchase restricted or illiquid securities, including Rule 144A securities, when they present attractive investment opportunities that otherwise meet the funds' criteria for selection. Rule 144A securities are securities that are privately placed with and traded among qualified institutional investors rather than the general public. Although Rule 144A securities are considered restricted securities, they are not necessarily illiquid. With respect to securities eligible for resale under Rule 144A, the staff of the Securities and Exchange Commission (SEC) has taken the position that the liquidity of such securities in the portfolio of a fund offering redeemable securities is a question of fact for the Board of Directors to determine, such determination to be based upon a consideration of the readily available trading markets and the review of any contractual restrictions. Accordingly, the Board of Directors is responsible for developing and establishing the guidelines and procedures for determining the liquidity of Rule 144A securities. As allowed by Rule 144A, the Board of Directors has delegated the day-to-day function of determining the liquidity of Rule 144A securities to the portfolio managers. The board retains the responsibility to monitor the implementation of the guidelines and procedures it has adopted. Because the secondary market for restricted securities is generally limited to certain qualified institutional investors, the liquidity of such securities may be limited accordingly and a fund may, from time to time, hold a Rule 144A or other security that is illiquid. In such an event, the portfolio managers will consider appropriate remedies to minimize the effect on such fund's liquidity. Short Sales A fund may engage in short sales for cash management purposes only if, at the time of the short sale, the fund owns or has the right to acquire securities equivalent in kind and amount to the securities being sold short. In a short sale, the seller does not immediately deliver the securities sold and is said to have a short position in those securities until delivery occurs. To make delivery to the purchaser, the executing broker borrows the securities being sold short on behalf of the seller. While the short position is maintained, the seller collateralizes its obligation to deliver the securities sold short in an amount equal to the proceeds of the short sale plus an additional margin amount established by the Board of Governors of the Federal Reserve. If a fund engages in a short sale, the fund's custodian will segregate cash, cash equivalents or other appropriate liquid securities on its records in an amount sufficient to meet the purchase price. There will be certain additional transaction costs associated with short sales, but the fund will endeavor to offset these costs with income from the investment of the cash proceeds of short sales. Short-Term Securities In order to meet anticipated redemptions, anticipated purchases of additional securities for a fund's portfolio, or, in some cases, for temporary defensive purposes, these funds may invest a portion of their assets in money market and other short-term securities. ------ 24 Examples of those securities include: * Securities issued or guaranteed by the U.S. government and its agencies and instrumentalities * Commercial Paper * Certificates of Deposit and Euro Dollar Certificates of Deposit * Bankers' Acceptances * Short-term notes, bonds, debentures or other debt instruments * Repurchase agreements * Money market funds Swap Agreements Each fund may invest in swap agreements, consistent with its investment objective and strategies. A fund may enter into a swap agreement in order to, for example, attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets; protect against currency fluctuations; attempt to manage duration to protect against any increase in the price of securities the fund anticipates purchasing at a later date; or gain exposure to certain markets in the most economical way possible. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or "swapped" between the parties are generally calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a "basket" of securities representing a particular index. Forms of swap agreements include, for example, interest rate swaps, under which fixed- or floating-rate interest payments on a specific principal amount are exchanged and total return swaps, under which one party agrees to pay the other the total return of a defined underlying asset (usually an index, stock, bond or defined portfolio of loans and mortgages) in exchange for fee payments, often a variable stream of cashflows based on LIBOR. The funds may enter into credit default swap agreements to hedge an existing position by purchasing or selling credit protection. Credit default swaps enable an investor to buy/sell protection against a credit event of a specific issuer. The seller of credit protection against a security or basket of securities receives an up-front or periodic payment to compensate against potential default event(s). The fund may enhance returns by selling protection or attempt to mitigate credit risk by buying protection. Market supply and demand factors may cause distortions between the cash securities market and the credit default swap market. Whether a fund's use of swap agreements will be successful depends on the advisor's ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Interest rate swaps could result in losses if interest rate changes are not correctly anticipated by the fund. Total return swaps could result in losses if the reference index, security, or investments do not perform as anticipated by the fund. Credit default swaps could result in losses if the fund does not correctly evaluate the creditworthiness of the issuer on which the credit default swap is based. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, a fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The funds will enter into swap agreements only with counterparties that meet certain standards of creditworthiness. Certain restrictions imposed on the funds by the Internal Revenue Code may limit the ------ 25 funds' ability to use swap agreements. The swaps market is an evolving market and is largely unregulated. It is possible that developments in the swaps market, including potential government regulation, could adversely affect a fund's ability to terminate existing swap agreements or to realize amounts to be received under such agreements. Tender Option Bonds Tender Option Bonds (TOBs) were created to increase the supply of high-quality, short-term tax-exempt obligations, and thus they are of particular interest to money market funds. However, Capital Value may purchase these instruments. TOBs are created by municipal bond dealers who purchase long-term tax-exempt bonds in the secondary market, place the certificates in trusts, and sell interests in the trusts with puts or other liquidity guarantees attached. The credit quality of the resulting synthetic short-term instrument is based on the put provider's short-term rating and the underlying bond's long-term rating. There is some risk that a remarketing agent will renege on a tender option agreement if the underlying bond is downgraded or defaults. Because of this, the portfolio managers monitor the credit quality of bonds underlying the funds' TOB holdings and intend to sell or put back any TOB if the rating on the underlying bond falls below the second-highest rating category designated by a rating agency. TRACERS(sm)/TRAINS(sm) Balanced may invest in TRACERS and TRAINS which represent ownership of a specified percentage of each security in an underlying pool of securities. Owners are entitled to receive a pro rata share of distributions from the underlying securities. In the event an underlying security is downgraded by a rating agency, that portion of the investment product will be redeemed and the underlying security will be distributed to the owner pro rata or the owner may receive cash proceeds. The risk of owning these products is the same as owning the individual securities, but they enable the fund to be more diversified by owning a single security. U.S. Government Securities U.S. Treasury bills, notes, zero-coupon bonds and other bonds are direct obligations of the U.S. Treasury, which has never failed to pay interest and repay principal when due. Treasury bills have initial maturities of one year or less, Treasury notes from two to 10 years, and Treasury bonds more than 10 years. Although U.S. Treasury securities carry little principal risk if held to maturity, the prices of these securities (like all debt securities) change between issuance and maturity in response to fluctuating market interest rates. A number of U.S. government agencies and instrumentalities issue debt securities. These agencies generally are created by Congress to fulfill a specific need, such as providing credit to home buyers or farmers. Among these agencies are the Federal Home Loan Banks, the Federal Farm Credit Banks, the Student Loan Marketing Association and the Resolution Funding Corporation. Some agency securities are backed by the full faith and credit of the U.S. government, and some are guaranteed only by the issuing agency. Agency securities typically offer somewhat higher yields than U.S. Treasury securities with similar maturities. However, these securities may involve greater risk of default than securities backed by the U.S. Treasury. Interest rates on agency securities may be fixed for the term of the investment (fixed-rate agency securities) or tied to prevailing interest rates (floating-rate agency securities). Interest rate resets on floating-rate agency securities generally occur at intervals of one year or less, based on changes in a predetermined interest rate index. ------ 26 Floating-rate agency securities frequently have caps limiting the extent to which coupon rates can be raised. The price of a floating-rate agency security may decline if its capped coupon rate is lower than prevailing market interest rates. Fixed- and floating-rate agency securities may be issued with a call date (which permits redemption before the maturity date). The exercise of a call may reduce an obligation's yield to maturity. Interest Rate Resets on Floating-Rate U.S. Government Agency Securities Interest rate resets on floating-rate U.S. government agency securities generally occur at intervals of one year or less in response to changes in a predetermined interest rate index. There are two main categories of indices: those based on U.S. Treasury securities and those derived from a calculated measure, such as a cost-of-funds index. Commonly used indices include the three-month, six-month and one-year Treasury bill rates; the two-year Treasury note yield; the Eleventh District Federal Home Loan Bank Cost of Funds Index (EDCOFI); and the London Interbank Offered Rate (LIBOR). Fluctuations in the prices of floating-rate U.S. government agency securities are typically attributed to differences between the coupon rates on these securities and prevailing market interest rates between interest rate reset dates. Variable- and Floating-Rate Obligations Variable- and floating-rate demand obligations (VRDOs and FRDOs) carry rights that permit holders to demand payment of the unpaid principal plus accrued interest, from the issuers or from financial intermediaries. Floating-rate securities, or floaters, have interest rates that change whenever there is a change in a designated base rate; variable-rate instruments provide for a specified, periodic adjustment in the interest rate, which typically is based on an index. These rate formulas are designed to result in a market value for the VRDO or FRDO that approximates par value. When-Issued and Forward Commitment Agreements The funds may sometimes purchase new issues of securities on a when-issued or forward commitment basis in which the transaction price and yield are each fixed at the time the commitment is made, but payment and delivery occur at a future date. For example, a fund may sell a security and at the same time make a commitment to purchase the same or a comparable security at a future date and specified price. Conversely, a fund may purchase a security and at the same time make a commitment to sell the same or a comparable security at a future date and specified price. These types of transactions are executed simultaneously in what are known as dollar-rolls, buy/sell back transactions, cash and carry, or financing transactions. For example, a broker-dealer may seek to purchase a particular security that a fund owns. The fund will sell that security to the broker-dealer and simultaneously enter into a forward commitment agreement to buy it back at a future date. This type of transaction generates income for the fund if the dealer is willing to execute the transaction at a favorable price in order to acquire a specific security. When purchasing securities on a when-issued or forward commitment basis, a fund assumes the rights and risks of ownership, including the risks of price and yield fluctuations. Market rates of interest on debt securities at the time of delivery may be higher or lower than those contracted for on the when-issued security. Accordingly, the value of that security may decline prior to delivery, which could result in a loss to the fund. While the fund will make commitments to purchase or sell securities with the intention of actually receiving or delivering them, it may sell the securities before the settlement date if doing so is deemed advisable as a matter of investment strategy. ------ 27 In purchasing securities on a when-issued or forward commitment basis, a fund will segregate cash, cash equivalents or other appropriate liquid securities on its record in an amount sufficient to meet the purchase price. To the extent a fund remains fully invested or almost fully invested at the same time it has purchased securities on a when-issued basis, there will be greater fluctuations in its net asset value than if it solely set aside cash to pay for when-issued securities. When the time comes to pay for the when-issued securities, the fund will meet its obligations with available cash, through the sale of securities, or, although it would not normally expect to do so, by selling the when-issued securities themselves (which may have a market value greater or less than the fund's payment obligation). Selling securities to meet when-issued or forward commitment obligations may generate taxable capital gains or losses. Zero-Coupon and Step-Coupon Securities The funds may purchase zero-coupon debt securities. Zero-coupon securities do not make regular cash interest payments, and are sold at a deep discount to their face value. The fund may also purchase step-coupon or step-rate debt securities. Instead of having a fixed coupon for the life of the security, coupon or interest payments may increase to predetermined rates at future dates. The issuer generally retains the right to call the security. Some step-coupon securities are issued with no coupon payments at all during an initial period, and only become interest-bearing at a future date; these securities are sold at a deep discount to their face value. Although zero-coupon and certain step-coupon securities may not pay current cash income, federal income tax law requires the holder to include in income each year the portion of any original issue discount and other noncash income on such securities accrued during that year. In order to continue to qualify for treatment as a regulated investment company under the Internal Revenue Code and avoid certain excise tax, the funds are required to make distributions of any original issue discount and other noncash income accrued for each year. Accordingly, the funds may be required to dispose of other portfolio securities, which may occur in periods of adverse market prices, in order to generate a case to meet these distribution requirements. INVESTMENT POLICIES Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the policies described below apply at the time a fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified limitation resulting from a change in a fund's assets will not be considered in determining whether it has complied with its investment policies. For purposes of a fund's investment policies, the party identified as the "issuer" of a municipal security depends on the form and conditions of the security. When the assets and revenues of a political subdivision are separate from those of the government that created the subdivision and the security is backed only by the assets and revenues of the subdivision, the subdivision is deemed the sole issuer. Similarly, in the case of an Industrial Development Bond, if the bond were backed only by the assets and revenues of a non-governmental user, the non-governmental user would be deemed the sole issuer. If, in either case, the creating government or some other entity were to guarantee the security, the guarantee would be considered a separate security and treated as an issue of the guaranteeing entity. Fundamental Investment Policies The funds' fundamental investment policies are set forth below. These investment policies and the funds' investment objectives set forth in their prospectuses may not be changed without approval of a majority of the outstanding votes of shareholders of a fund, as determined in accordance with the Investment Company Act. ------ 28 SUBJECT POLICY -------------------------------------------------------------------------------- Senior A fund may not issue senior securities, except Securities as permitted under the Investment Company Act. -------------------------------------------------------------------------------- Borrowing A fund may not borrow money, except that a fund may borrow for temporary or emergency purposes (not for leveraging or investment) in an amount not exceeding 33-1/3% of the fund's total assets (including the amount borrowed) less liabilities (other than borrowings). -------------------------------------------------------------------------------- Lending A fund may not lend any security or make any other loan if, as a result, more than 33-1/3% of the fund's total assets would be lent to other parties, except (i) through the purchase of debt securities in accordance with its investment objective, policies and limitations or (ii) by engaging in repurchase agreements with respect to portfolio securities. -------------------------------------------------------------------------------- Real Estate A fund may not purchase or sell real estate unless acquired as a result of ownership of securities or other instruments. This policy shall not prevent a fund from investing in securities or other instruments backed by real estate or securities of companies that deal in real estate or are engaged in the real estate business. -------------------------------------------------------------------------------- Concentration A fund (except Focused Growth and Veedot) may not concentrate its investments in securities of issuers in a particular industry (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities). -------------------------------------------------------------------------------- Underwriting A fund may not act as an underwriter of securities issued by others, except to the extent that the fund may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of restricted securities. -------------------------------------------------------------------------------- Commodities A fund may not purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments, provided that this limitation shall not prohibit the fund from purchasing or selling options and futures contracts or from investing in securities or other instruments backed by physical commodities. -------------------------------------------------------------------------------- Control A fund may not invest for purposes of exercising control over management. -------------------------------------------------------------------------------- For purposes of the investment policies relating to lending and borrowing, the funds have received an exemptive order from the SEC regarding an interfund lending program. Under the terms of the exemptive order, the funds may borrow money from or lend money to other American Century-advised funds that permit such transactions. All such transactions will be subject to the limits for borrowing and lending set forth above. The funds will borrow money through the program only when the costs are equal to or lower than the costs of short-term bank loans. Interfund loans and borrowings normally extend only overnight, but can have a maximum duration of seven days. The funds will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). The funds may have to borrow from a bank at a higher interest rate if an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment opportunity or additional borrowing costs. For purposes of the funds' investment policy relating to borrowing, short positions held by the funds are not considered borrowings. For purposes of the investment policy relating to concentration, a fund shall not purchase any securities that would cause 25% or more of the value of the fund's total assets at the time of purchase to be invested in the securities of one or more issuers conducting their principal business activities in the same industry, provided that (a) there is no limitation with respect to obligations issued or guaranteed by the U.S. government, any state, territory or possession of the United States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions and repurchase agreements secured by such obligations, (b) wholly owned finance companies will be considered to be in the industries of their parents if their activities are primarily related to financing the activities of their parents, ------ 29 (c) utilities will be divided according to their services, for example, gas, gas transmission, electric and gas, electric, and telephone will each be considered a separate industry, and (d) personal credit and business credit businesses will be considered separate industries. Nonfundamental Investment Policies In addition, the funds are subject to the following investment policies that are not fundamental and may be changed by the Board of Directors. SUBJECT POLICY -------------------------------------------------------------------------------- Leveraging A fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the fund. -------------------------------------------------------------------------------- Liquidity A fund may not purchase any security or enter into a repurchase agreement if, as a result, more than 15% of its net assets would be invested in illiquid securities. Illiquid securities include repurchase agreements not entitling the holder to payment of principal and interest within seven days, and securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market. -------------------------------------------------------------------------------- Short Sales A fund may not sell securities short, unless it owns or has the right to obtain securities equivalent in kind and amount to the securities sold short, and provided that transactions in futures contracts and options are not deemed to constitute selling securities short. -------------------------------------------------------------------------------- Margin A fund may not purchase securities on margin, except to obtain such short-term credits as are necessary for the clearance of transactions, and provided that margin payments in connection with futures contracts and options on futures contracts shall not constitute purchasing securities on margin. -------------------------------------------------------------------------------- Futures A fund may enter into futures contracts and write and and buy put and call options relating to futures Options contracts. A fund may not, however, enter into leveraged futures transactions if it would be possible for the fund to lose more than the notional value of the investment. -------------------------------------------------------------------------------- Issuers A fund may invest in the equity securities of issuers with with limited operating histories. See INVESTMENT Limited IN ISSUERS WITH LIMITED OPERATING HISTORIES under FUND Operating INVESTMENTS AND RISKS. An issuer is considered to Histories have a limited operating history if that issuer has a record of less than three years of continuous operation. Periods of capital formation, incubation, consolidations, and research and development may be considered in determining whether a particular issuer has a record of three years of continuous operation. -------------------------------------------------------------------------------- For purposes of the funds' investment policy relating to leveraging, short positions held by the funds are not considered borrowings. The Investment Company Act imposes certain additional restrictions upon the funds' ability to acquire securities issued by insurance companies, broker-dealers, underwriters or investment advisors, and upon transactions with affiliated persons as defined by the Act. It also defines and forbids the creation of cross and circular ownership. Neither the SEC nor any other agency of the federal or state government participates in or supervises the management of the funds or their investment practices or policies. TEMPORARY DEFENSIVE MEASURES For temporary defensive purposes, each fund (except Balanced) may invest in securities that may not fit its investment objective or its stated market. During a temporary defensive period, a fund may invest a portion of its assets in money market and other short-term securities. Examples of those securities include: * securities issued or guaranteed by the U.S. government and its agencies and instrumentalities; ------ 30 * commercial paper; * interest-bearing bank accounts or certificates of deposit; * short-term notes, bonds, or other debt instruments; * repurchase agreements; and * money market funds. To the extent a fund assumes a defensive position, it will not be pursuing its investment objective. PORTFOLIO TURNOVER The portfolio turnover rate of each fund is listed in the Financial Highlights table in that fund's prospectus. Capital Value Fund The portfolio managers of Capital Value seek to minimize realized capital gains by keeping portfolio turnover low and generally holding portfolio investments for long periods. Because a higher turnover rate may increase taxable capital gains, the managers carefully weigh the potential benefits of short-term investing against the tax impact such investing would have on the fund's shareholders. However, the portfolio managers may sell securities to realize losses that can be used to offset realized capital gains. They will take such actions when they believe the tax benefits from realizing losses offset the near-term investment potential of that security. Other Funds With respect to each other fund, the managers may sell securities without regard to the length of time the security has been held. Accordingly, each fund's portfolio turnover rate may be substantial. The portfolio managers intend to purchase a given security whenever they believe it will contribute to the stated objective of a particular fund. In order to achieve each fund's investment objective, the managers may sell a given security regardless of the length of time it has been held in the portfolio, and regardless of the gain or loss realized on the sale. The managers may sell a portfolio security if they believe that the security is not fulfilling its purpose because, among other things, it did not live up to the managers' expectations, because it may be replaced with another security holding greater promise, because it has reached its optimum potential, because of a change in the circumstances of a particular company or industry or in general economic conditions, or because of some combination of such reasons. When a general decline in security prices is anticipated, the equity funds may decrease or eliminate entirely their equity positions and increase their cash positions, and when a general rise in price levels is anticipated, the equity funds may increase their equity positions and decrease their cash positions. However, it should be expected that the funds will, under most circumstances, be essentially fully invested in equity securities. Because investment decisions are based on a particular security's anticipated contribution to a fund's investment objective, the managers believe that the rate of portfolio turnover is irrelevant when they determine that a change is required to pursue the fund's investment objective. As a result, a fund's annual portfolio turnover rate cannot be anticipated and may be higher than that of other mutual funds with similar investment objectives. Higher turnover would generate correspondingly greater brokerage commissions, which is a cost the funds pay directly. Portfolio turnover also may affect the character of capital gains realized and distributed by the fund, if any, because short-term capital gains are characterized as ordinary income. Because the managers do not take portfolio turnover rate into account in making investment decisions, (1) the managers have no intention of maintaining any particular rate of portfolio turnover, whether high or low, and (2) the portfolio turnover rates in the past should not be considered as representative of the rates that will be attained in the future. ------ 31 Variations in a fund's portfolio turnover rate from year to year may be due to a fluctuating volume of shareholder purchase and redemption activity, varying market conditions, and/or changes in the managers' investment outlook. The decrease in Fundamental Equity's portfolio turnover in 2007 was reflective of market conditions, which allowed the portfolio managers to hold stocks for longer periods. The decrease in portfolio turnover in 2007 for Heritage and Vista was due to complementary market conditions to the funds' disciplines. Accordingly, the funds were able to hold large positions for longer periods of time. The decrease in portfolio turnover for New Opportunities and New Opportunities II in 2007 can be attributed to decreased sector rotation in the market. Select's portfolio turnover in 2006 was significantly higher than normal. This was due to a change in the portfolio management team, which resulted in enhancements to the fund's investment process. The decrease in Veedot's portfolio turnover in 2007 can be attributed to the development of advanced models for the fund's buy and sell process. MANAGEMENT The individuals listed below serve as directors or officers of the funds. Each director serves until his or her successor is duly elected and qualified or until he or she retires. Mandatory retirement age for independent directors is 72. Those listed as interested directors are "interested" primarily by virtue of their engagement as directors and/or officers of, or ownership interest in, American Century Companies, Inc. (ACC) or its wholly owned, direct or indirect, subsidiaries, including the funds' investment advisor, American Century Investment Management, Inc. (ACIM or the advisor); the funds' principal underwriter, American Century Investment Services, Inc. (ACIS); and the funds' transfer agent, American Century Services, LLC (ACS). The other directors (more than three-fourths of the total number) are independent; that is, they have never been employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACIM, ACIS and ACS. The directors serve in this capacity for seven registered investment companies in the American Century family of funds. All persons named as officers of the funds also serve in similar capacities for the other 14 investment companies in the American Century family of funds advised by ACIM, or American Century Global Investment Management, Inc. (ACGIM), a wholly owned subsidiary of ACIM, unless otherwise noted. Only officers with policy-making functions are listed. No officer is compensated for his or her service as an officer of the funds. The listed officers are interested persons of the funds and appointed or re-appointed on an annual basis.

(DST) under which DST would provide back-office software and support services for transfer agency services provided by ACS (the Agreement). ACS pays DST fees based in part on the number of accounts and the number and type of transactions processed for those accounts. Through December 31, 2007, DST received $20,416,010 in fees from ACS. DST's total revenue for the calendar year ended December 31, 2007, was approximately $2.3 billion. Ms. Strandjord is a director of DST and a holder of 22,642 shares and possesses options to acquire an additional 55,890 shares of DST common stock, the sum of which is less than one percent (1%) of the shares outstanding. Because of her official duties as a director of DST, she may be deemed to have an "indirect interest" in the Agreement. However, the Board of Directors of the funds was not required to nor did it approve or disapprove the Agreement, since the provision of the services covered by the Agreement is within the discretion of ACS. DST was chosen by ACS for its industry-leading role in providing cost-effective back-office support for mutual fund service providers such as ACS. DST is the largest mutual fund transfer agent, servicing more than 75 million mutual fund accounts on its shareholder recordkeeping system. Ms. Strandjord's role as a director of DST was not considered by ACS; she was not involved in any way with the negotiations between ACS and DST; and her status as a director of either DST or the funds was not a factor in the negotiations. The Board of Directors of the funds has concluded that the existence of this Agreement does not impair Ms. Strandjord's ability to serve as an independent director under the Investment Company Act. THE BOARD OF DIRECTORS The Board of Directors oversees the management of the funds and meets at least quarterly to review reports about fund operations. Although the Board of Directors does not manage the funds, it has hired the advisor to do so. The directors, in carrying out their fiduciary duty under the Investment Company Act, are responsible for approving new and existing management contracts with the funds' advisor. The board has the authority to manage the business of the funds on behalf of their investors, and it has all powers necessary or convenient to carry out that responsibility. Consequently, the directors may adopt bylaws providing for the regulation and management of the affairs of the funds and may amend and repeal them to the extent that such bylaws do not reserve that right to the funds' investors. They may fill vacancies in or reduce the number of board members, and may elect and remove such officers and appoint and terminate such agents as they consider appropriate. They may appoint from their own number and establish and terminate one or more committees consisting of two or more directors who may exercise the powers and authority of the board to the extent that the directors determine. They may, in general, delegate such authority as they consider desirable to any officer of the funds, to any committee of the board, to any agent or employee of the funds, or to any custodian, transfer or investor servicing agent, or principal underwriter. Any determination as to what is in the interests of the funds made by the directors in good faith shall be conclusive. The Advisory Board The funds also have an Advisory Board. Members of the Advisory Board, if any, function like fund directors in many respects, but do not possess voting power. Advisory Board members attend all meetings of the Board of Directors and the independent directors and receive any materials distributed in connection with such meetings. Advisory Board members may be considered as candidates to fill vacancies on the Board of Directors. ------ 35 Committees The board has five standing committees to oversee specific functions of the funds' operations. Information about these committees appears in the table below. The director first named serves as chairman of the committee. -------------------------------------------------------------------------------- COMMITTEE: Executive MEMBERS: Donald H. Pratt, M. Jeannine Strandjord, Jonathan S. Thomas FUNCTION: The Executive Committee performs the functions of the Board of Directors between board meetings, subject to the limitations on its power set out in the Maryland General Corporation Law, and except for matters required by the Investment Company Act to be acted upon by the whole board. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 3 -------------------------------------------------------------------------------- COMMITTEE: Compliance and Shareholder Communications MEMBERS: M. Jeannine Strandjord, Andrea C. Hall, Ph.D., James A. Olson, Donald H. Pratt FUNCTION: The Compliance and Shareholder Communications Committee reviews the results of the funds' compliance testing program, reviews quarterly reports from the communications advisor to the board regarding various compliance matters and monitors the implementation of the funds' Code of Ethics, including any violations. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 4 -------------------------------------------------------------------------------- COMMITTEE: Audit MEMBERS: Thomas A. Brown, Gale E. Sayers, Timothy S. Webster FUNCTION: The Audit Committee approves the engagement of the funds' independent registered public accounting firm, recommends approval of such engagement to the independent directors, and oversees the activities of the funds' independent registered public accounting firm. The committee receives reports from the advisor's Internal Audit Department, which is accountable to the committee. The committee also receives reporting about compliance matters affecting the funds. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 4 -------------------------------------------------------------------------------- COMMITTEE: Governance MEMBERS: Andrea C. Hall, Ph.D., Donald H. Pratt, Gale E. Sayers FUNCTION: The Governance Committee primarily considers and recommends individuals for nomination as directors. The names of potential director candidates are drawn from a number of sources, including recommendations from members of the board, management (in the case of interested directors only) and shareholders. See NOMINATIONS OF DIRECTORS below. This committee also reviews and makes recommendations to the board with respect to the composition of board committees and other board-related matters, including its organization, size, composition, responsibilities, functions and compensation. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 2 -------------------------------------------------------------------------------- COMMITTEE: Fund Performance Review MEMBERS: Timothy S. Webster, Thomas A. Brown, Andrea C. Hall, Ph.D., James A. Olson, Donald H. Pratt, Gale E. Sayers, M. Jeannine Strandjord FUNCTION: The Fund Performance Review Committee reviews quarterly the investment activities and strategies used to manage fund assets. The committee regularly receives reports from portfolio managers and other investment personnel concerning the funds' investments. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 4 Nominations of Directors -------------------------------------------------------------------------------- As indicated in the table above, the Governance Committee is responsible for identifying, evaluating and recommending qualified candidates for election to the funds' Board of Directors. While the Governance Committee largely considers nominees from searches that it conducts, the Committee will consider director candidates submitted by shareholders. Any shareholder wishing to submit a candidate for consideration should send the following information to the Corporate Secretary, American Century Funds, P.O. Box 410141, Kansas City, MO 64141 or by email to corporatesecretary@americancentury.com: * Shareholder's name, the fund name and number of fund shares owned and length of period held; * Name, age and address of the candidate; ------ 36 * A detailed resume describing, among other things, the candidate's educational background, occupation, employment history, financial knowledge and expertise and material outside commitments (e.g., memberships on other boards and committees, charitable foundations, etc.); * Any other information relating to the candidate that is required to be disclosed in solicitations of proxies for election of directors in an election contest pursuant to Regulation 14A under the Securities Exchange Act of 1934; * Number of fund shares owned by the candidate and length of time held; * A supporting statement which (i) describes the candidate's reasons for seeking election to the Board of Directors and (ii) documents his/her ability to satisfy the director qualifications described in the board's policy; and * A signed statement from the candidate confirming his/her willingness to serve on the Board of Directors. The Corporate Secretary will promptly forward such materials to the Governance Committee chairman. The Corporate Secretary also will maintain copies of such materials for future reference by the Governance Committee when filling board positions. Shareholders may submit potential director candidates at any time pursuant to these procedures. The Governance Committee will consider such candidates if a vacancy arises or if the board decides to expand its membership, and at such other times as the Governance Committee deems necessary or appropriate. Compensation of Directors The directors serve as directors for seven American Century investment companies. Each director who is not an interested person as defined in the Investment Company Act receives compensation for service as a member of the board of all such companies based on a schedule that takes into account the number of meetings attended and the assets of the funds for which the meetings are held. These fees and expenses are divided among these investment companies based, in part, upon their relative net assets. Under the terms of the management agreement with the advisor, the funds are responsible for paying such fees and expenses. The following table shows the aggregate compensation paid by the funds for the periods indicated and by the investment companies served by the board to each director who is not an interested person as defined in the Investment Company Act.

OLSON JOINED THE FUNDS' ADVISORY BOARD ON JANUARY 1, 2006 AND WAS ELECTED DIRECTOR ON JULY 27, 2007. ------ 37 The funds have adopted the American Century Mutual Funds' Independent Directors' Deferred Compensation Plan. Under the plan, the independent directors may defer receipt of all or any part of the fees to be paid to them for serving as directors of the funds. All deferred fees are credited to an account established in the name of the directors. The amounts credited to the account then increase or decrease, as the case may be, in accordance with the performance of one or more of the American Century funds that are selected by the director. The account balance continues to fluctuate in accordance with the performance of the selected fund or funds until final payment of all amounts credited to the account. Directors are allowed to change their designation of mutual funds from time to time. No deferred fees are payable until such time as a director resigns, retires or otherwise ceases to be a member of the Board of Directors. Directors may receive deferred fee account balances either in a lump sum payment or in substantially equal installment payments to be made over a period not to exceed 10 years. Upon the death of a director, all remaining deferred fee account balances are paid to the director's beneficiary or, if none, to the director's estate. The plan is an unfunded plan and, accordingly, the funds have no obligation to segregate assets to secure or fund the deferred fees. To date, the funds have voluntarily funded their obligations. The rights of directors to receive their deferred fee account balances are the same as the rights of a general unsecured creditor of the funds. The plan may be terminated at any time by the administrative committee of the plan. If terminated, all deferred fee account balances will be paid in a lump sum. OWNERSHIP OF FUND SHARES The directors owned shares in the funds as of December 31, 2007, as shown in the table below.

They permit personnel subject to the codes to invest in securities, including securities that may be purchased or held by the funds, provided that they first obtain approval from the compliance department before making such investments. PROXY VOTING GUIDELINES The advisor is responsible for exercising the voting rights associated with the securities purchased and/or held by the funds. In exercising its voting obligations, the advisor is guided by general fiduciary principles. It must act prudently, solely in the interest of the funds, and for the exclusive purpose of providing benefits to them. The advisor attempts to consider all factors of its vote that could affect the value of the investment. The funds' Board of Directors has approved the advisor's proxy voting guidelines to govern the advisor's proxy voting activities. The advisor and the board have agreed on certain significant contributors to shareholder value with respect to a number of matters that are often the subject of proxy solicitations for shareholder meetings. The proxy voting guidelines specifically address these considerations and establish a framework for the advisor's consideration of the vote that would be appropriate for the funds. In particular, the proxy voting guidelines outline principles and factors to be considered in the exercise of voting authority for proposals addressing: ------ 39 * Election of Directors * Ratification of Selection of Auditors * Equity-Based Compensation Plans * Anti-Takeover Proposals * Cumulative Voting * Staggered Boards * "Blank Check" Preferred Stock * Elimination of Preemptive Rights * Non-targeted Share Repurchase * Increase in Authorized Common Stock * "Supermajority" Voting Provisions or Super Voting Share Classes * "Fair Price" Amendments * Limiting the Right to Call Special Shareholder Meetings * Poison Pills or Shareholder Rights Plans * Golden Parachutes * Reincorporation * Confidential Voting * Opting In or Out of State Takeover Laws * Shareholder Proposals Involving Social, Moral or Ethical Matters * Anti-Greenmail Proposals * Changes to Indemnification Provisions * Non-Stock Incentive Plans * Director Tenure * Directors' Stock Options Plans * Director Share Ownership Finally, the proxy voting guidelines establish procedures for voting of proxies in cases in which the advisor may have a potential conflict of interest. Companies with which the advisor has direct business relationships could theoretically use these relationships to attempt to unduly influence the manner in which American Century votes on matters for the funds. To ensure that such a conflict of interest does not affect proxy votes cast for the funds, all discretionary (including case-by-case) voting for these companies will be voted in direct consultation with a committee of the independent directors of the funds. In addition, to avoid any potential conflict of interest that may arise when one American Century fund owns shares of another American Century fund, the advisor will "echo vote" such shares, if possible. That is, it will vote the shares in the same proportion as the vote of all other holders of the shares. Shares of American Century "NT" funds will be voted in the same proportion as the vote of the shareholders of the corresponding American Century policy portfolio for proposals common to both funds. For example, NT Growth Fund shares will be echo voted in accordance with the votes of Growth Fund shareholders. In all other cases, the shares will be voted in direct consultation with a committee of the independent directors of the voting fund. A copy of the advisor's proxy voting guidelines and information regarding how the advisor voted proxies relating to portfolio securities during the most recent 12-month period ended June 30 are available on the ABOUT US page at americancentury.com. The advisor's proxy voting record also is available on the SEC's website at sec.gov. ------ 40 DISCLOSURE OF PORTFOLIO HOLDINGS The advisor (ACIM) has adopted policies and procedures with respect to the disclosure of fund portfolio holdings and characteristics, which are described below. Distribution to the Public Full portfolio holdings for each fund will be made available for distribution 30 days after the end of each calendar quarter, and will be posted on americancentury.com at approximately the same time. This disclosure is in addition to the portfolio disclosure in annual and semi-annual shareholder reports, and on Form N-Q, which disclosures are filed with the Securities and Exchange Commission within 60 days of each fiscal quarter end and also posted on americancentury.com at the time the filings are made. Top 10 holdings for each fund will be made available for distribution monthly 30 days after the end of each month, and will be posted on americancentury.com at approximately the same time. Certain portfolio characteristics determined to be sensitive and confidential will be made available for distribution monthly 30 days after the end of each month, and will be posted on americancentury.com at approximately the same time. Characteristics not deemed confidential will be available for distribution at any time. The advisor may make determinations of confidentiality on a fund-by-fund basis, and may add or delete characteristics from those considered confidential at any time. So long as portfolio holdings are disclosed in accordance with the above parameters, the advisor makes no distinction among different categories of recipients, such as individual investors, institutional investors, intermediaries that distribute the funds' shares, third-party service providers, rating and ranking organizations, and fund affiliates. Because this information is publicly available and widely disseminated, the advisor places no conditions or restrictions on, and does not monitor, its use. Nor does the advisor require special authorization for its disclosure. Accelerated Disclosure The advisor recognizes that certain parties, in addition to the advisor and its affiliates, may have legitimate needs for information about portfolio holdings and characteristics prior to the times prescribed above. Such accelerated disclosure is permitted under the circumstances described below. Ongoing Arrangements Certain parties, such as investment consultants who provide regular analysis of fund portfolios for their clients and intermediaries who pass through information to fund shareholders, may have legitimate needs for accelerated disclosure. These needs may include, for example, the preparation of reports for customers who invest in the funds, the creation of analyses of fund characteristics for intermediary or consultant clients, the reformatting of data for distribution to the intermediary's or consultant's clients, and the review of fund performance for ERISA fiduciary purposes. In such cases, accelerated disclosure is permitted if the service provider enters an appropriate non-disclosure agreement with the funds' distributor in which it agrees to treat the information confidentially until the public distribution date and represents that the information will be used only for the legitimate services provided to its clients (i.e., not for trading). Non-disclosure agreements require the approval of an attorney in the advisor's legal department. The advisor's compliance department receives quarterly reports detailing which clients received accelerated disclosure, what they received, when they received it and the purposes of such disclosure. Compliance personnel are required to confirm that an appropriate non-disclosure agreement has been obtained from each recipient identified in the reports. ------ 41 Those parties who have entered into non-disclosure agreements as of January 29, 2008 are as follows: * Aetna, Inc. * American Fidelity Assurance Co. * AUL/American United Life Insurance Company * Ameritas Life Insurance Corporation * Annuity Investors Life Insurance Company * Asset Services Company L.L.C. * Bell Globemedia Publishing * Bellwether Consulting, LLC * Bidart & Ross * Callan Associates, Inc. * Cambridge Financial Services, Inc. * Capital Cities, LLC * Charles Schwab & Co., Inc. * Cleary Gull Inc. * Commerce Bank, N.A. * Connecticut General Life Insurance Company * Consulting Services Group, LLC * CRA RogersCasey, Inc. * Defined Contribution Advisors, Inc. * EquiTrust Life Insurance Company * Evaluation Associates, LLC * Evergreen Investments * Farm Bureau Life Insurance Company * First MetLife Investors Insurance Company * Fund Evaluation Group, LLC * The Guardian Life Insurance & Annuity Company, Inc. * Hammond Associates, Inc. * Hewitt Associates LLC * ICMA Retirement Corporation * ING Life Insurance Company & Annuity Co. * Iron Capital Advisors * J.P. Morgan Retirement Plan Services LLC * Jefferson National Life Insurance Company * Jefferson Pilot Financial * Jeffrey Slocum & Associates, Inc. * Kansas City Life Insurance Company * Kmotion, Inc. * Liberty Life Insurance Company * The Lincoln National Life Insurance Company * Lipper Inc. * Manulife Financial * Massachusetts Mutual Life Insurance Company ------ 42 * Merrill Lynch * MetLife Investors Insurance Company * MetLife Investors Insurance Company of California * Midland National Life Insurance Company * Minnesota Life Insurance Company * Morgan Keegan & Co., Inc. * Morgan Stanley & Co., Incorporated * Morningstar Associates LLC * Morningstar Investment Services, Inc. * National Life Insurance Company * Nationwide Financial * New England Pension Consultants * Northwestern Mutual Life Insurance Co. * NT Global Advisors, Inc. * NYLIFE Distributors, LLC * Principal Life Insurance Company * Prudential Financial * Rocaton Investment Advisors, LLC * S&P Financial Communications * Scudder Distributors, Inc. * Security Benefit Life Insurance Co. * Smith Barney * SunTrust Bank * Symetra Life Insurance Company * Trusco Capital Management * Union Bank of California, N.A. * The Union Central Life Insurance Company * VALIC Financial Advisors * VALIC Retirement Services Company * Vestek Systems, Inc. * Wachovia Bank, N.A. * Wells Fargo Bank, N.A. Once a party has executed a non-disclosure agreement, it may receive any or all of the following data for funds in which its clients have investments or are actively considering investment: (1) Full holdings quarterly as soon as reasonably available; (2) Full holdings monthly as soon as reasonably available; (3) Top 10 holdings monthly as soon as reasonably available; and (4) Portfolio characteristics monthly as soon as reasonably available. The types, frequency and timing of disclosure to such parties vary. In most situations, the information provided pursuant to a non-disclosure agreement is limited to certain portfolio characteristics and/or top 10 holdings, which information is provided on a monthly basis. In limited situations, and when approved by a member of the legal department and responsible chief investment officer, full holdings may be provided. ------ 43 Single Event Requests In certain circumstances, the advisor may provide fund holding information on an accelerated basis outside of an ongoing arrangement with manager-level or higher authorization. For example, from time to time the advisor may receive requests for proposals (RFPs) from consultants or potential clients that request information about a fund's holdings on an accelerated basis. As long as such requests are on a one-time basis, and do not result in continued receipt of data, such information may be provided in the RFP as of the most recent month end regardless of lag time. Such information will be provided with a confidentiality legend and only in cases where the advisor has reason to believe that the data will be used only for legitimate purposes and not for trading. In addition, the advisor occasionally may work with a transition manager to move a large account into or out of a fund. To reduce the impact to the fund, such transactions may be conducted on an in-kind basis using shares of portfolio securities rather than cash. The advisor may provide accelerated holdings disclosure to the transition manager with little or no lag time to facilitate such transactions, but only if the transition manager enters into an appropriate non-disclosure agreement. Service Providers Various service providers to the funds and the funds' advisor must have access to some or all of the funds' portfolio holdings information on an accelerated basis from time to time in the ordinary course of providing services to the funds. These service providers include the funds' custodian (daily, with no lag), auditors (as needed) and brokers involved in the execution of fund trades (as needed). Additional information about these service providers and their relationships with the funds and the advisor are provided elsewhere in this statement of additional information. Additional Safeguards The advisor's policies and procedures include a number of safeguards designed to control disclosure of portfolio holdings and characteristics so that such disclosure is consistent with the best interests of fund shareholders. First, the frequency with which this information is disclosed to the public, and the length of time between the date of the information and the date on which the information is disclosed, are selected to minimize the possibility of a third party improperly benefiting from fund investment decisions to the detriment of fund shareholders. Second, distribution of portfolio holdings information, including compliance with the advisor's policies and the resolution of any potential conflicts that may arise, is monitored quarterly. Finally, the funds' Board of Directors exercises oversight of disclosure of the funds' portfolio securities. The board has received and reviewed a summary of the advisor's policy and is informed on a quarterly basis of any changes to or violations of such policy detected during the prior quarter. Neither the advisor nor the funds receive any compensation from any party for the distribution of portfolio holdings information. The advisor reserves the right to change its policies and procedures with respect to the distribution of portfolio holdings information at any time. There is no guarantee that these policies and procedures will protect the funds from the potential misuse of holdings information by individuals or firms in possession of such information. ------ 44 THE FUNDS' PRINCIPAL SHAREHOLDERS As of February 1, 2008, the following shareholders, beneficial or of record, owned more than 5% of the outstanding shares of any class of a fund.

OTHERWISE, AMERICAN CENTURY HAS NO INFORMATION CONCERNING BENEFICIAL OWNERSHIP OF FUND SHARES. The funds are unaware of any other shareholders, beneficial or of record, who own more than 5% of any class of a fund's outstanding shares. The funds are unaware of any other shareholders, beneficial or of record, who own more than 25% of the voting securities of the corporation. A shareholder owning of record or beneficially more than 25% of the corporation's outstanding shares may be considered ------ 55 a controlling person. The vote of any such person could have a more significant effect on matters presented at a shareholders' meeting than votes of other shareholders. As of February 1, 2008, the officers and directors of the funds, as a group, owned less than 1% of any class of a fund's outstanding shares. SERVICE PROVIDERS The funds have no employees. To conduct the funds' day-to-day activities, the corporation has hired a number of service providers. Each service provider has a specific function to fill on behalf of the funds that is described below. ACIM, ACS and ACIS are wholly owned, directly or indirectly, by ACC. James E. Stowers, Jr., controls ACC by virtue of his ownership of a majority of its voting stock. INVESTMENT ADVISOR American Century Investment Management, Inc. (ACIM) serves as the investment advisor for each of the funds. A description of the responsibilities of the advisor appears in each prospectus under the heading MANAGEMENT. For services provided to each fund, the advisor receives a unified management fee based on a percentage of the net assets of each fund. For more information about the unified management fee, see THE INVESTMENT ADVISOR under the heading MANAGEMENT in each fund's prospectus. The amount of the fee is calculated daily and paid monthly in arrears. For each fund with a stepped fee schedule, the rate of the fee is determined by applying the formula indicated in the table below. This formula takes into account all of the advisor's assets under management in the fund's investment strategy (strategy assets). Strategy assets include assets of the fund and certain assets of other clients of the advisor outside the American Century fund family that use very similar investment teams and strategies. For a fund with a corresponding NT fund, strategy assets for both funds also include the assets of the other. The use of strategy assets, rather than fund assets, in calculating the fee rate for a particular fund could allow the fund to realize scheduled cost savings more quickly. However, it is possible that a fund's strategy assets will not include assets of other client accounts or that any such assets may not be sufficient to result in a lower fee rate. The management fee schedules for the funds appear below.

-------------------------------------------------------------------------------- On each calendar day, each class of each fund accrues a management fee that is equal to the class's management fee rate (as calculated pursuant to the above schedules) times the net assets of the class divided by 365 (366 in leap years). On the first business day of each month, the funds pay a management fee to the advisor for the previous month. The management fee is the sum of the daily fee calculations for each day of the previous month. The management agreement between the corporation and the advisor shall continue in effect until the earlier of the expiration of two years from the date of its execution or until the first meeting of fund shareholders following such execution and for as long thereafter as its continuance is specifically approved at least annually by (1) the funds' Board of Directors, or a majority of outstanding shareholder votes (as defined in the Investment Company Act) and (2) the vote of a majority of the directors of the funds who are not parties to the agreement or interested persons of the advisor, cast in person at a meeting called for the purpose of voting on such approval. The management agreement states that the funds' Board of Directors or a majority of outstanding shareholder votes may terminate the management agreement at any time without payment of any penalty on 60 days' written notice to the advisor. The management agreement shall be automatically terminated if it is assigned. The management agreement states the advisor shall not be liable to the funds or their shareholders for anything other than willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties. The management agreement also provides that the advisor and its officers, directors and employees may engage in other business, render services to others, and devote time and attention to any other business whether of a similar or dissimilar nature. Certain investments may be appropriate for the funds and also for other clients advised by the advisor. Investment decisions for the funds and other clients are made with a view to achieving their respective investment objectives after consideration of such factors as their current holdings, availability of cash for investment and the size of their investment generally. A particular security may be bought ------ 60 or sold for only one client or fund, or in different amounts and at different times for more than one but less than all clients or funds. A particular security may be bought for one client or fund on the same day it is sold for another client or fund, and a client or fund may hold a short position in a particular security at the same time another client or fund holds a long position. In addition, purchases or sales of the same security may be made for two or more clients or funds on the same date. The advisor has adopted procedures designed to ensure such transactions will be allocated among clients and funds in a manner believed by the advisor to be equitable to each. In some cases this procedure could have an adverse effect on the price or amount of the securities purchased or sold by a fund. The advisor may aggregate purchase and sale orders of the funds with purchase and sale orders of its other clients when the advisor believes that such aggregation provides the best execution for the funds. The Board of Directors has approved the policy of the advisor with respect to the aggregation of portfolio transactions. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios pro rata based on order size. The advisor will not aggregate portfolio transactions of the funds unless it believes such aggregation is consistent with its duty to seek best execution on behalf of the funds and the terms of the management agreement. The advisor receives no additional compensation or remuneration as a result of such aggregation. Unified management fees incurred by each fund for the fiscal periods ended October 31, 2007, 2006 and 2005, are indicated in the following tables.

Currently, Mason Street Advisors LLC (MSA) serves as subadvisor to the Small Cap Growth Fund and Mid Cap Growth Fund under a subadvisory agreement between the advisor and MSA dated March 30, 2006, and approved by shareholders on March 30, 2006. The subadvisory agreement continues for an initial period until July 31, 2007, and thereafter so long as continuance is specifically approved at least annually by vote of a majority of the fund's outstanding voting securities or by vote of a majority of the fund's directors, provided that in either event the continuance is also approved by a majority of those directors who are neither parties to the agreement nor interested persons of any such party, cast in person at a meeting called for the purpose of voting on such approval. The subadvisory agreement is subject to termination without penalty on 60 days' written notice by the advisor, the Board of Directors, a majority of the fund's outstanding shares, or MSA, and will terminate automatically in the event of its assignment or termination of the investment advisory agreement between the fund and the advisor. The subadvisory agreement provides that MSA will make investment decisions for the funds in accordance with the funds' investment objectives, policies, and restrictions, and whatever additional written guidelines it may receive from the advisor from time to time. For the services it provides to Mid Cap Growth, the advisor pays MSA a monthly fee at an annual rate of 0.550% on the first $50 million of the fund's average daily net assets, 0.500% on the next $200 million of average daily net assets, 0.450% on the next $250 million of average daily net assets and 0.400% on average daily net assets over $500 million. For the services it provides to Small Cap Growth, the advisor pays MSA a monthly fee at an annual rate of 0.700% on the first $35 million of the fund's average daily net assets, 0.650% on the next $65 million of average daily net assets, 0.600% on the next $400 million of average daily net assets and 0.550% on average daily net assets over $500 million.

Potential conflicts include, for example, conflicts among investment strategies and conflicts in the allocation of investment opportunities. American Century has adopted policies and procedures that are designed to minimize the effects of these conflicts. Responsibility for managing American Century client portfolios is organized according to investment discipline. Investment disciplines include, for example, core equity, small- and mid-cap growth, large-cap growth, value, international, fixed-income, asset allocation, and sector funds. Within each discipline are one or more portfolio teams responsible for managing specific client portfolios. Generally, client portfolios with similar strategies are managed by the same team using the same objective, approach, and philosophy. Accordingly, portfolio holdings, position sizes, and industry and sector exposures tend to be similar across similar portfolios, which minimizes the potential for conflicts of interest. For each investment strategy, one portfolio is generally designated as the "policy portfolio." Other portfolios with similar investment objectives, guidelines and restrictions, if any, are referred to as "tracking portfolios." When managing policy and tracking portfolios, a portfolio team typically purchases and sells securities across all portfolios that the team manages. American Century's trading systems include various order entry programs that assist in the management of multiple portfolios, such as the ability to purchase or sell the same relative amount of one security across several funds. In some cases a tracking portfolio may have additional restrictions or limitations that cause it to be managed separately from the policy portfolio. Portfolio managers make purchase and sale decisions for such portfolios alongside the policy portfolio to the extent the overlap is appropriate, and separately, if the overlap is not. American Century may aggregate orders to purchase or sell the same security for multiple portfolios when it believes such aggregation is consistent with its duty to seek best execution on behalf of its clients. Orders of certain client portfolios may, by investment restriction or otherwise, be determined not available for aggregation. American Century has adopted policies and procedures to minimize the risk that a client portfolio could be systematically advantaged or disadvantaged in connection with the aggregation of orders. To the extent equity trades are aggregated, shares purchased or sold are generally allocated to the participating portfolios PRO RATA based on order size. Because initial public offerings (IPOs) are usually available in limited supply and in amounts too small to permit across-the-board pro rata allocations, American Century has adopted special procedures designed to promote a fair and equitable allocation of IPO securities among clients over time. Fixed-income securities transactions are not executed through a centralized trading desk. Instead, portfolio teams are responsible for executing trades with broker/dealers in a predominantly dealer marketplace. Trade allocation decisions are made by the portfolio manager at the time of trade execution and orders entered on the fixed-income order management system. Finally, investment of American Century's corporate assets in proprietary accounts may raise additional conflicts of interest. To mitigate these potential conflicts of interest, American Century has adopted policies and procedures intended to provide that trading in proprietary accounts is performed in a manner that does not give improper advantage to American Century to the detriment of client portfolios. Compensation American Century portfolio manager compensation is structured to align the interests of portfolio managers with those of the shareholders whose assets they manage. For the fiscal year ended October 31, 2007, it included the components described below, each of which is determined with reference to a number of factors such as overall performance, market competition, and internal equity. Compensation is not directly tied to the value of assets held in client portfolios. ------ 65 Base Salary Portfolio managers receive base pay in the form of a fixed annual salary. Bonus A significant portion of portfolio manager compensation takes the form of an annual incentive bonus tied to performance. Bonus payments are determined by a combination of factors. One factor is fund investment performance. Fund investment performance is generally measured by a combination of one- and three-year pre-tax performance relative to various benchmarks and/or internally-customized peer groups, such as those indicated below. The performance comparison periods may be adjusted based on a fund's inception date or a portfolio manager's tenure on the fund.

FUNDS ARE THEN ELIMINATED FROM THE PEER GROUP BASED ON A STANDARDIZED METHODOLOGY DESIGNED TO RESULT IN A FINAL PEER GROUP THAT IS BOTH MORE STABLE OVER THE LONG TERM (I.E., HAS LESS PEER TURNOVER) AND THAT MORE CLOSELY REPRESENTS THE FUND'S TRUE PEERS BASED ON INTERNAL INVESTMENT MANDATES. (2) PERFORMANCE OF NT GROWTH AND NT VISTA IS NOT SEPARATELY CONSIDERED IN DETERMINING PORTFOLIO MANAGER COMPENSATION. Portfolio managers may have responsibility for multiple American Century mutual funds. In such cases, the performance of each is assigned a percentage weight appropriate for the portfolio manager's relative levels of responsibility. Portfolio managers also may have responsibility for other types of similarly managed portfolios. If the performance of a similarly managed account is considered for purposes of compensation, it is either measured in the same way as a comparable American Century mutual fund (i.e., relative to the performance of a benchmark and/or peer group) or relative to the performance of such mutual fund. A second factor in the bonus calculation relates to the performance of a number of American Century funds managed according to one of the following investment styles: U.S. growth, U.S. value, international and fixed-income. Performance is measured for each product individually as described above and then combined to ------ 66 create an overall composite for the product group. These composites may measure one-year performance (equal weighted) or a combination of one- and three-year performance (equal or asset weighted) depending on the portfolio manager's responsibilities and products managed. This feature is designed to encourage effective teamwork among portfolio management teams in achieving long-term investment success for similarly styled portfolios. A portion of portfolio managers' bonuses may be tied to individual performance goals, such as research projects and the development of new products. Restricted Stock Plans Portfolio managers are eligible for grants of restricted stock of ACC. These grants are discretionary, and eligibility and availability can vary from year to year. The size of an individual's grant is determined by individual and product performance as well as other product-specific considerations. Grants can appreciate/depreciate in value based on the performance of the ACC stock during the restriction period (generally three years). Deferred Compensation Plans Portfolio managers are eligible for grants of deferred compensation. These grants are used in very limited situations, primarily for retention purposes. Grants are fixed and can appreciate/depreciate in value based on the performance of the American Century mutual funds in which the portfolio manager chooses to invest them.

(2) INCLUDES $43 MILLION IN SMALL CAP GROWTH. Compensation of Portfolio Managers MSA has adopted a system of compensation for portfolio managers that seeks to attract, motivate and retain high quality investment personnel and align the financial interests of the portfolio managers with the performance of MSA and its clients. A portfolio manager's compensation consists primarily of the following three components: a base salary, annual variable compensation and, for certain portfolio managers, long-term variable compensation. Eligibility and participation in the annual and long-term variable compensation programs is determined on a year-to-year basis. Each portfolio manager is also eligible to participate in benefit plans and programs available generally to all employees of MSA. A portfolio manager's total compensation is determined through a process that combines both objective and subjective criteria. Initially, at the beginning of each year, compensation targets are determined for each portfolio manager based on market ------ 69 factors and the skill, experience and tenure of the portfolio manager. The compensation target is then allocated among base salary, annual variable compensation and long-term variable compensation based on a formula for each portfolio manager. At the end of the year, the portfolio manager's performance is evaluated using both objective and subjective criteria. Primary consideration is given to the historic investment performance of accounts managed by the portfolio manager over both a one-year and a four-year period, with more weight typically being given to the longer-term performance. The performance of each account managed by the portfolio manager is measured against a relevant peer group and/or an applicable benchmark, as deemed appropriate. If a portfolio manager manages more than one account, performance is weighted based on a combination of factors, including the number and type of accounts managed, and the assets in each account. The evaluation process also includes a subjective evaluation of competencies or behaviors deemed important to achieving MSA's overall business objectives. Subjective criteria may include considerations such as management and supervisory responsibilities, market factors, complexity of investment strategies, length of service, team building efforts and successes, risk management initiatives and leadership contributions. A portfolio manager's compensation is then determined by applying a multiplier (which can be greater or less than 1.0) based on the annual evaluation of the objective and subjective criteria to the targeted compensation. Long-term variable pay grants are made on an annual basis and are credited to a deferred account that accrues interest on the balances. Awarded grants vest over a three to five-year vesting period and are paid upon vesting. Conflicts of Interest Conflicts of interest may arise when a portfolio manager is responsible for the management of more than one account. The principal types of these potential conflicts may include: TIME AND ATTENTION. The management of multiple funds and/or accounts may give rise to potential conflicts of interest as the portfolio manager must allocate his or her time and investment ideas across multiple funds and accounts. This could result in a portfolio manager devoting unequal time and attention to the management of each fund and/or other accounts. The effect of this potential conflict may be more pronounced where funds and/or accounts overseen by a particular portfolio manager have different objectives, benchmarks, time horizons, and fees. LIMITED INVESTMENT OPPORTUNITIES. If a portfolio manager identifies a limited investment opportunity that may be suitable for multiple funds and/or accounts, the opportunity may be allocated among these several funds or accounts, which may limit a fund's ability to take full advantage of the investment opportunity. MSA seeks to manage such potential conflicts by using procedures intended to provide a fair allocation of buy and sell opportunities among funds and other accounts. VARIATION IN INCENTIVES. A conflict of interest may arise where the financial or other benefits available to the portfolio manager differ among the funds and/or accounts that he or she manages. If the structure of the investment adviser's management fee and/or the portfolio manager's compensation differs among funds and/or accounts (such as where certain funds or accounts pay higher management fees or performance-based management fees), the portfolio manager might be motivated to help certain funds and/or accounts over others. In addition, the portfolio manager might be motivated to favor funds and/or accounts in which he or she has an interest or in which the investment adviser and/or its affiliates have interests. Similarly, the desire to maintain assets under management or to enhance the portfolio manager's performance record or to derive other rewards, financial or otherwise, could influence the portfolio manager in affording preferential treatment to those funds and/or accounts that could most significantly benefit the portfolio manager. ------ 70 PERSONAL ACCOUNTS. Portfolio managers may be permitted to purchase and sell securities for their own personal accounts or the personal accounts of family members, which could potentially influence the portfolio manager's decisions with respect to purchasing or selling the same securities for the fund. To mitigate this potential conflict of interest, MSA has adopted Codes of Ethics or other policies and procedures governing the personal securities transactions of its portfolio managers. DIFFERING STRATEGIES. At times, a portfolio manager may determine that an investment opportunity may be appropriate for only some of the funds and/or accounts for which he or she exercises investment responsibility, or may decide that certain of the funds and/or accounts should take differing positions with respect to a particular security. In these cases, the portfolio manager may place separate transactions for one or more funds or accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment or benefit of one or more other funds and/or accounts. MSA and the fund have adopted compliance polices and procedures, as applicable, that are designed to address these, and other, types of conflicts of interest. There is no guarantee, however, that such policies and procedures will be able to detect and/or prevent every situation where a conflict arises.

The advisor, or the subadvisor, as the case may be, receives statistical and other information and services, including research, without cost from brokers and dealers. The advisor or subadvisor evaluates such information and services, together with all other information that it may have, in supervising and managing the investments of the funds. Because such information and services may vary in amount, quality and reliability, their influence in selecting brokers varies from none to very substantial. The advisor or subadvisor intends to continue to place some of the funds' brokerage business with one or more brokers who provide information and services. Such information and services will be in addition to and not in lieu of services required to be performed by the advisor. The advisor does not utilize brokers that provide such information and services for the purpose of reducing the expense of providing required services to the funds. In the fiscal years ended October 31, 2007, 2006 and 2005, the brokerage commissions including, as applicable, futures commissions, of each fund are listed in the following table.

(2) NOVEMBER 30, 2004 (INCEPTION) THROUGH OCTOBER 31, 2005. (3) REFLECTS COMMISSIONS PAID BY THE PREDECESSOR FUND AS OF THE FISCAL YEAR ENDED MARCH 31. (4) FOR THE PERIOD APRIL 1, 2006 THROUGH OCTOBER 31, 2006, THE FUND PAID $199,909. (5) MAY 12, 2006 (INCEPTION) THROUGH OCTOBER 31, 2006. (6) FOR THE PERIOD APRIL 1, 2006 THROUGH OCTOBER 31, 2006, THE FUND PAID $85,004. Brokerage commissions paid by a fund may vary significantly from year to year as a result of changing asset levels throughout the year, portfolio turnover, varying market conditions, and other factors. The decrease in brokerage commissions paid by Balanced over the last three fiscal years is due to less active use of principal bids. The increase in brokerage commissions paid by Fundamental Equity and New Opportunities II over the last three fiscal years is due to increased net assets ------ 73 of each fund. The increase in brokerage commissions paid by Select for the fiscal year ended October 31, 2006 was due to increased portfolio turnover. The decrease in brokerage commissions paid by Veedot over the last three fiscal years is due to decreased portfolio turnover. The brokerage commissions paid by the funds may exceed those that another broker might have charged for effecting the same transactions, because of the value of the brokerage and research services provided by the broker. Research services furnished by brokers through whom the funds effect securities transactions may be used by the advisor in servicing all of its accounts, and not all such services may be used by the advisor in managing the portfolios of the funds. The staff of the SEC has expressed the view that the best price and execution of over-the-counter transactions in portfolio securities may be secured by dealing directly with principal market makers, thereby avoiding the payment of compensation to another broker. In certain situations, the officers of the funds and the advisor believe that the facilities, expert personnel and technological systems of a broker often enable the funds to secure as good a net price by dealing with a broker instead of a principal market maker, even after payment of the compensation to the broker. The funds regularly place their over-the-counter transactions with principal market makers, but also may deal on a brokerage basis when utilizing electronic trading networks or as circumstances warrant. The funds' distributor (ACIS) and investment advisor (ACIM) are wholly owned, directly or indirectly, by ACC. JPMorgan Chase & Co. (JPM) is an equity investor in ACC. The funds paid J.P.

In many transactions, the selection of the broker or dealer is determined by the availability of the desired security and its offering price. In other transactions, the selection of the broker or dealer is a function of market selection and price negotiation, as well as the broker's general execution and operational and financial capabilities in the type of transaction involved. The advisor will seek to obtain prompt execution of orders at the most favorable prices or yields. The advisor may choose to purchase and sell portfolio securities from and to dealers who provide statistical and other information and services, including research, to the funds and to the advisor. Such information or services will be in addition to, and not in lieu of, the services required to be performed by the advisor, and the expenses of the advisor will not necessarily be reduced as a result of the receipt of such supplemental information. The funds generally purchase and sell debt securities through principal transactions, meaning the funds normally purchase securities on a net basis directly from the issuer or a primary market-maker acting as principal for the securities. The funds do not pay brokerage commissions on these transactions, although the purchase price for debt securities usually includes an undisclosed compensation. Purchases of securities from underwriters typically include a commission or concession paid by the issuer to the underwriter, and purchases from dealers serving as market-makers typically include a dealer's mark-up (i.e., a spread between the bid and asked prices). ------ 75 REGULAR BROKER-DEALERS As of the end of its most recently completed fiscal year, each of the funds listed below owned securities of its regular brokers or dealers (as defined by Rule 10b-1 under the Investment Company Act of 1940) or of their parent companies.

In addition, each series (or fund) may be divided into separate classes. See MULTIPLE CLASS STRUCTURE, which follows. Additional funds and classes may be added without a shareholder vote. Each fund votes separately on matters affecting that fund exclusively. Voting rights are not cumulative, so investors holding more than 50% of the corporation's (all funds') outstanding shares may be able to elect a Board of Directors. The corporation undertakes dollar-based voting, meaning that the number of votes ------ 76 a shareholder is entitled to is based upon the dollar amount of the shareholder's investment. The election of directors is determined by the votes received from all the corporation's shareholders without regard to whether a majority of shares of any one fund voted in favor of a particular nominee or all nominees as a group. The assets belonging to each series are held separately by the custodian and the shares of each series represent a beneficial interest in the principal, earnings and profit (or losses) of investments and other assets held for each series. Within their respective series, all shares have equal redemption rights. Each share, when issued, is fully paid and non-assessable. Each shareholder has rights to dividends and distributions declared by the fund he or she owns and to the net assets of such fund, upon its liquidation or dissolution, proportionate to his or her share ownership interest in the fund. MULTIPLE CLASS STRUCTURE The corporation's Board of Directors has adopted a multiple class plan pursuant to Rule 18f-3 adopted by the SEC. The plan is described in the prospectus of any fund that offers more than one class. Pursuant to such plan, the funds may issue up to seven classes of shares: Investor Class, Institutional Class, A Class, B Class, C Class, R Class and Advisor Class. Not all funds offer all seven classes. The Investor Class is made available to investors directly from American Century and/or through some financial intermediaries. Investor Class shares charge a single unified management fee, without any load or commission payable to American Century. Additional information regarding eligibility for Investor Class shares may be found in the funds' prospectuses. The Institutional Class is made available to institutional shareholders or through financial intermediaries whose clients do not require the same level of shareholder and administrative services from the advisor as Investor Class shareholders. As a result, the advisor is able to charge this class a lower total management fee. The A, B, C and Advisor Classes also are made available through financial intermediaries, for purchase by individual investors who receive advisory and personal services from the intermediary. The R Class is made available through financial intermediaries and is generally used in 401(k) and other retirement plans. The unified management fee for the A, B, C, R and Advisor Classes is the same as for Investor Class, but the A, B, C, R and Advisor Class shares each are subject to a separate Master Distribution and Individual Shareholder Services Plan (the A Class Plan, B Class Plan, C Class Plan, R Class Plan and Advisor Class Plan, respectively, and collectively, the plans) described below. The plans have been adopted by the funds' Board of Directors in accordance with Rule 12b-1 adopted by the SEC under the Investment Company Act. Rule 12b-1 Rule 12b-1 permits an investment company to pay expenses associated with the distribution of its shares in accordance with a plan adopted by its Board of Directors and approved by its shareholders. Pursuant to such rule, the Board of Directors of the funds' A, B, C, R and Advisor Classes have approved and entered into the A Class Plan, B Class Plan, C Class Plan, R Class Plan and Advisor Class Plan, respectively. The plans are described below. In adopting the plans, the Board of Directors (including a majority of directors who are not interested persons of the funds [as defined in the Investment Company Act], hereafter referred to as the independent directors) determined that there was a reasonable likelihood that the plans would benefit the funds and the shareholders of the affected class. Some of the anticipated benefits include improved name recognition of the funds generally; and growing assets in existing funds, which helps retain and attract investment management talent, provides a better environment for improving fund performance, and can lower the total expense ratio ------ 77 for funds with stepped-fee schedules. Pursuant to Rule 12b-1, information about revenues and expenses under the plans is presented to the Board of Directors quarterly for its consideration in continuing the plans. Continuance of the plans must be approved by the Board of Directors, including a majority of the independent directors, annually. The plans may be amended by a vote of the Board of Directors, including a majority of the independent directors, except that the plans may not be amended to materially increase the amount to be spent for distribution without majority approval of the shareholders of the affected class. The plans terminate automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent directors or by vote of a majority of outstanding shareholder votes of the affected class. All fees paid under the plans will be made in accordance with Section 2830 of the Conduct Rules of the Financial Industry Regulatory Authority (FINRA). A Class Plan As described in the prospectuses, the A Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services. Certain recordkeeping and administrative services that are provided by the funds' transfer agent for the Investor Class shareholders may be performed by a plan sponsor (or its agents) or by a financial intermediary for A Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services. To enable the funds' shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds' Board of Directors has adopted the A Class Plan. Pursuant to the A Class Plan, the A Class pays the funds' distributor 0.25% annually of the average daily net asset value of the A Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services (as described below) and for distribution services, including past distribution services (as described below). This payment is fixed at 0.25% and is not based on expenses incurred by the distributor. During the fiscal year ended October 31, 2007, the aggregate amount of fees paid under the A Class Plan was: Capital Growth $7,177 Focused Growth $5(1) Fundamental Equity $296,375 Heritage $102,220(2) Mid Cap Growth $83,604 New Opportunities II $371,621 Select $67,090(3) Small Cap Growth $90,211(4) Ultra $103,775(2) (1) FOR THE PERIOD SEPTEMBER 28, 2007 TO OCTOBER 31, 2007. (2) FOR THE PERIOD SEPTEMBER 4, 2007 TO OCTOBER 31, 2007. (3) EFFECTIVE SEPTEMBER 4, 2007, THE FUND'S A CLASS WAS COMBINED WITH THE ADVISOR CLASS. ADDITIONALLY, THE ADVISOR CLASS WAS RENAMED A CLASS AND BECAME SUBJECT TO THE A CLASS PLAN. FROM NOVEMBER 1, 2006 TO SEPTEMBER 3, 2007, THE AMOUNT OF FEES PAID UNDER THE A CLASS PLAN WAS $49,758. FROM SEPTEMBER 4, 2007 TO OCTOBER 31, 2007, THE AMOUNT OF FEES PAID UNDER THE A CLASS PLAN WAS $17,332. (4) EFFECTIVE APRIL 1, 2006 THROUGH MARCH 31, 2008, AMERICAN CENTURY AGREED TO A TWO-YEAR WAIVER OF RULE 12B-1 FEES FOR CERTAIN CLASSES OF THE FUND. TAKING IN ACCOUNT THE WAIVER, THE 12B-1 FEE IS 0.10%. ------ 78 The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the A Class shares for the services described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses. Payments may be made for a variety of individual shareholder services, including, but not limited to: (a) providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals; (b) creating investment models and asset allocation models for use by shareholders in selecting appropriate funds; (c) conducting proprietary research about investment choices and the market in general; (d) periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation; (e) consolidating shareholder accounts in one place; and (f) other individual services. Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of A Class shares, which services may include but are not limited to: (a) paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell A Class shares pursuant to selling agreements; (b) compensating registered representatives or other employees of the distributor who engage in or support distribution of the funds' A Class shares; (c) paying and compensating expenses (including overhead and telephone expenses) of the distributor; (d) printing prospectuses, statements of additional information and reports for other-than-existing shareholders; (e) preparing, printing and distributing sales literature and advertising materials provided to the funds' shareholders and prospective shareholders; (f) receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports; (g) providing facilities to answer questions from prospective shareholders about fund shares; (h) complying with federal and state securities laws pertaining to the sale of fund shares; (i) assisting shareholders in completing application forms and selecting dividend and other account options; (j) providing other reasonable assistance in connection with the distribution of fund shares; (k) organizing and conducting sales seminars and payments in the form of transactional and compensation or promotional incentives; (l) profit on the foregoing; (m) paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of the FINRA; and (n) such other distribution and services activities as the advisor determines may be paid for by the funds pursuant to the terms of the agreement between the corporation and the funds' distributor and in accordance with Rule 12b-1 of the Investment Company Act. ------ 79 B Class Plan As described in the prospectuses, the B Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services. Certain recordkeeping and administrative services that are provided by the funds' transfer agent for the Investor Class shareholders may be performed by a plan sponsor (or its agents) or by a financial intermediary for B Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services. To enable the funds' shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds' Board of Directors has adopted the B Class Plan. Pursuant to the B Class Plan, the B Class pays the funds' distributor 1.00% annually of the average daily net asset value of the B Class shares, 0.25% of which is paid for certain ongoing individual shareholder and administrative services (as described below) and 0.75% of which is paid for distribution services, including past distribution services (as described below). The payment is fixed at 1.00% and is not based on expenses incurred by the distributor. During the fiscal year ended October 31, 2007, the aggregate amount of fees paid under the B Class Plan was: Capital Growth $10,656 Focused Growth $21(1) Fundamental Equity $28,695 Heritage $47(1) Mid Cap Growth $60,965(2) New Opportunities II $37,575 Select $54,787 Small Cap Growth $63,318(3) Ultra $21(1) (1) FOR THE PERIOD SEPTEMBER 28, 2007 TO OCTOBER 31, 2007.

C Class Plan As described in the prospectuses, the C Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services. ------ 81 Certain recordkeeping and administrative services that are provided by the funds' transfer agent for the Investor Class shareholders may be performed by a plan sponsor (or its agents) or by a financial intermediary for C Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services. To enable the funds' shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds' Board of Directors has adopted the C Class Plan. Pursuant to the C Class Plan, the C Class pays the funds' distributor 1.00% annually of the average daily net asset value of the C Class shares, 0.25% of which is paid for certain ongoing individual shareholder and administrative services (as described below) and 0.75% of which is paid for distribution services, including past distribution services (as described below). This payment is fixed at 1.00% and is not based on expenses incurred by the distributor.

Payments may be made for a variety of individual shareholder services, including, but not limited to: (a) providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals; (b) creating investment models and asset allocation models for use by shareholders in selecting appropriate funds; (c) conducting proprietary research about investment choices and the market in general; (d) periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation; (e) consolidating shareholder accounts in one place; and (f) other individual services. Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of C Class shares, which services may include but are not limited to: (a) paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell C Class shares pursuant to selling agreements; ------ 82 (b) compensating registered representatives or other employees of the distributor who engage in or support distribution of the funds' C Class shares; (c) paying and compensating expenses (including overhead and telephone expenses) of the distributor; (d) printing prospectuses, statements of additional information and reports for other-than-existing shareholders; (e) preparing, printing and distributing sales literature and advertising materials provided to the funds' shareholders and prospective shareholders; (f) receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports; (g) providing facilities to answer questions from prospective shareholders about fund shares; (h) complying with federal and state securities laws pertaining to the sale of fund shares; (i) assisting shareholders in completing application forms and selecting dividend and other account options; (j) providing other reasonable assistance in connection with the distribution of fund shares; (k) organizing and conducting of sales seminars and payments in the form of transactional and compensation or promotional incentives; (l) profit on the foregoing; (m) paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of the FINRA; and (n) such other distribution and services activities as the advisor determines may be paid for by the funds pursuant to the terms of the agreement between the corporation and the funds' distributor and in accordance with Rule 12b-1 of the Investment Company Act. R Class Plan As described in the prospectuses, the R Class shares of the funds are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services. Certain recordkeeping and administrative services that are provided by the funds' transfer agent for the Investor Class shareholders may be performed by a plan sponsor (or its agents) or by a financial intermediary for R Class investors. In addition to such services, the financial intermediaries provide various individual shareholder and distribution services. To enable the funds' shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the funds' Board of Directors has adopted the R Class Plan. Pursuant to the R Class Plan, the R Class pays the funds' distributor 0.50% annually of the average daily net asset value of the R Class shares. The distributor may use these fees to pay for certain ongoing shareholder and administrative services (as described below) and for distribution services, including past distribution services (as described below). This payment is fixed at 0.50% and is not based on expenses incurred by the distributor. During the fiscal year ended October 31, 2007, the aggregate amount of fees paid under the R Class Plan was: ------ 83 Capital Growth $145 Focused Growth $11(1) Fundamental Equity $1,597 Growth $8,467 Heritage 11(1) Mid Cap Growth $471 New Opportunities II $11(1) Select $134 Small Cap Growth $160 Ultra $29,908 Vista $6,946 (1) FOR THE PERIOD SEPTEMBER 28, 2007 TO OCTOBER 31, 2007. The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the R Class shares for the services, as described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses. Payments may be made for a variety of individual shareholder services, including, but not limited to: (a) providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals; (b) creating investment models and asset allocation models for use by shareholders in selecting appropriate funds; (c) conducting proprietary research about investment choices and the market in general; (d) periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation; (e) consolidating shareholder accounts in one place; and (f) other individual services. Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of R Class shares, which services may include but are not limited to: (a) paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell R Class shares pursuant to selling agreements; (b) compensating registered representatives or other employees of the distributor who engage in or support distribution of the funds' R Class shares; (c) paying and compensating expenses (including overhead and telephone expenses) of the distributor; (d) printing prospectuses, statements of additional information and reports for other-than-existing shareholders; (e) preparing, printing and distributing sales literature and advertising materials provided to the funds' shareholders and prospective shareholders; (f) receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports; (g) providing facilities to answer questions from prospective shareholders about fund shares; (h) complying with federal and state securities laws pertaining to the sale of fund shares; ------ 84 (i) assisting shareholders in completing application forms and selecting dividend and other account options; (j) providing other reasonable assistance in connection with the distribution of fund shares; (k) organizing and conducting of sales seminars and payments in the form of transactional and compensation or promotional incentives; (l) profit on the foregoing; (m) paying service fees for providing personal, continuing services to investors, as contemplated by the Conduct Rules of the FINRA; and (n) such other distribution and services activities as the advisor determines may be paid for by the funds pursuant to the terms of the agreement between the corporation and the funds' distributor and in accordance with Rule 12b-1 of the Investment Company Act. Advisor Class Plan(1) As described in the prospectuses, the funds' Advisor Class shares are made available to participants in employer-sponsored retirement plans and to persons purchasing through broker-dealers, banks, insurance companies, and other financial intermediaries that provide various administrative, shareholder and distribution services. The funds' distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the funds' shares and/or the use of the funds' shares in various investment products or in connection with various financial services. Certain recordkeepking and administrative services that are provided by the funds' transfer agent for the Investor Class shareholders may be performed by a plan sponsor (or its agents) or by a financial intermediary for Advisor Class investors. In addition to such services, the financial intermediaries provide various distribution services. To make the funds' shares available through such plans and financial intermediaries, and to compensate them for these services, the funds' Board of Directors has adopted the Advisor Class Plan. Prior to September 4, 2007 for Balanced, Heritage, Select, Ultra and Vista, and December 3, 2007 for Capital Value and Growth, the Advisor Class Plan required the Advisor Class to pay 0.50% annually of the aggregate average daily net assets of the funds' Advisor Class shares, 0.25% for certain ongoing shareholder and administrative services (as described below). However, at shareholder meetings on July 27, 2007 and September 25, 2007, the Advisor Class shareholders approved a decrease in the fee required by the Advisor Class Plan of 0.25%, and a corresponding increase in the Advisor Class management fee. This change was made because the administrative services portion of the 12b-1 fee does not need to be made out of the 12b-1 plan, but may properly be made out of the funds' unified fee, consistent with the other classes of the funds. This change resulted in no difference in the overall fee for the Advisor Class, but will lower the amount of the 12b-1 fee charged under the Advisor Class Plan from and after September 4, 2007 for Balanced and Vista, and December 3, 2007 for Capital Value and Growth. After those dates, pursuant to the Advisor Class Plan, the Advisor Class pays the funds' distributor 0.25% annually of the aggregate average daily net assets of the funds' Advisor Class shares, which is paid for certain ongoing individual shareholder services (as described below) and for distribution services, including past distribution services (as described below). This payment is fixed at 0.25% and is not based on expenses incurred by the distributor. During the fiscal year ended October 31, 2007, the aggregate amount of fees paid under the Advisor Class Plan was: (1) EFFECTIVE SEPTEMBER 4, 2007, THE ADVISOR CLASSES OF HERITAGE AND ULTRA WERE RENAMED A CLASS AND BECAME SUBJECT TO THE A CLASS PLAN. EFFECTIVE SEPTEMBER 4, 2007, THE A CLASS OF SELECT WAS COMBINED WITH THE ADVISOR CLASS. ADDITIONALLY, THE ADVISOR CLASS WAS RENAMED A CLASS AND BECAME SUBJECT TO THE A CLASS PLAN. ------ 85 Balanced $70,285(1) Capital Value $86,354 Growth $683,964 Heritage $442,366(2) Select $83,600(2) Ultra $1,274,018(2) Vista $1,110,362(3) (1) FROM NOVEMBER 1, 2006 TO SEPTEMBER 3, 2007, THE AGGREGATE AMOUNT OF FEES PAID UNDER THE ADVISOR CLASS PLAN WAS $65,030. FROM SEPTEMBER 4, 2007 TO OCTOBER 31, 2007, THE AGGREGATE AMOUNT OF FEES PAID UNDER THE ADVISOR CLASS PLAN WAS $5,255. (2) FOR THE PERIOD NOVEMBER 1, 2006 TO SEPTEMBER 4, 2007. (3) FROM NOVEMBER 1, 2006 TO SEPTEMBER 3, 2007, THE AGGREGATE AMOUNT OF FEES PAID UNDER THE ADVISOR CLASS PLAN WAS $966,038. FROM SEPTEMBER 4, 2007 TO OCTOBER 31, 2007, THE AGGREGATE AMOUNT OF FEES PAID UNDER THE ADVISOR CLASS PLAN WAS $144,324. The distributor then makes these payments to the financial intermediaries (including underwriters and broker-dealers, who may use some of the proceeds to compensate sales personnel) who offer the Advisor Class shares in payment for provision of the services, as described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses. Prior to September 4, 2007 for Balanced, Heritage, Select, Ultra and Vista, and December 3, 2007 for Capital Value and Growth, 0.25% of the fee charged to the Advisor Class Plan was for a variety of shareholder services, including, but not limited to: (a) receiving, aggregating and processing purchase, exchange and redemption requests from beneficial owners (including contract owners of insurance products that utilize the funds as underlying investment media) of shares and placing purchase, exchange and redemption orders with the funds' distributor; (b) providing shareholders with a service that invests the assets of their accounts in shares pursuant to specific or pre-authorized instructions; (c) processing dividend payments from a fund on behalf of shareholders and assisting shareholders in changing dividend options, account designations and addresses; (d) providing and maintaining elective services such as check writing and wire transfer services; (e) acting as shareholder of record and nominee for beneficial owners; (f) maintaining account records for shareholders and/or other beneficial owners; (g) issuing confirmations of transactions; (h) providing subaccounting with respect to shares beneficially owned by customers of third parties or providing the information to a fund as necessary for such subaccounting; (i) preparing and forwarding investor communications from the funds (such as proxies, shareholder reports, annual and semi-annual financial statements and dividend, distribution and tax notices) to shareholders and/or other beneficial owners; and (j) providing other similar administrative and sub-transfer agency services. Shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. During the fiscal year ended October 31, 2007, the amount of fees paid under the Advisor Class Plan for shareholder services was: ------ 86 Balanced $32,515(1) Capital Value $43,177 Growth $341,982 Heritage $221,183(1) Select $41,800(1) Ultra $637,009(1) Vista $483,019(1) (1) FOR THE PERIOD NOVEMBER 1, 2006 TO SEPTEMBER 4, 2007. Although these services are still being provided by the financial intermediaries, after September 4, 2007 for Balanced and Vista, and December 3, 2007 for Capital Value and Growth, they will be reimbursed by the funds' advisor out of the unified management fee rather than out of a 12b-1 fee, as described above. Distribution services include any activity undertaken or expense incurred that is primarily intended to result in the sale of Advisor Class shares, which services may include but are not limited to: (a) paying sales commissions, on-going commissions and other payments to brokers, dealers, financial institutions or others who sell Advisor Class shares pursuant to selling agreements; (b) compensating registered representatives or other employees of the distributor who engage in or support distribution of the funds' Advisor Class shares; (c) paying and compensating expenses (including overhead and telephone expenses) of the distributor; (d) printing prospectuses, statements of additional information and reports for other-than-existing shareholders; (e) preparing, printing and distributing of sales literature and advertising materials provided to the funds' shareholders and prospective shareholders; (f) receiving and answering correspondence from prospective shareholders, including distributing prospectuses, statements of additional information, and shareholder reports; (g) providing facilities to answer questions from prospective shareholders about fund shares; (h) complying with federal and state securities laws pertaining to the sale of fund shares; (i) assisting shareholders in completing application forms and selecting dividend and other account options; (j) providing other reasonable assistance in connection with the distribution of fund shares; (k) organizing and conducting of sales seminars and payments in the form of transactional and compensation or promotional incentives; (l) profit on the foregoing; (m) paying service fees for the provision of personal, continuing services to investors, as contemplated by the Conduct Rules of the FINRA; and (n) such other distribution and services activities as the advisor determines may be paid for by the funds pursuant to the terms of the agreement between the corporation and the funds' distributor and in accordance with Rule 12b-1 of the Investment Company Act. During the fiscal year ended October 31, 2007, the amount of fees paid under the Advisor Class Plan for distribution services was: ------ 87 Balanced $32,515(1) Capital Value $43,177 Growth $341,982 Heritage $221,183(1) Select $41,800(1) Ultra $637,009(1) Vista $483,019(1) (1) FOR THE PERIOD NOVEMBER 1, 2006 TO SEPTEMBER 4, 2007. Beginning on September 4, 2007 for Balanced and Vista, and December 3, 2007 for Capital Value and Growth, a portion of the 12b-1 fee will be paid to the distributor for certain individual shareholder services. These payments may be made for a variety of individual shareholder services, including, but not limited to: (a) providing individualized and customized investment advisory services, including the consideration of shareholder profiles and specific goals; (b) creating investment models and asset allocation models for use by shareholders in selecting appropriate funds; (c) conducting proprietary research about investment choices and the market in general; (d) periodic rebalancing of shareholder accounts to ensure compliance with the selected asset allocation; (e) consolidating shareholder accounts in one place; and (f) other individual services. Individual shareholder services do not include those activities and expenses that are primarily intended to result in the sale of additional shares of the funds. Sales Charges The sales charges applicable to the A, B and C Classes of the funds are described in the prospectuses for those classes in the section titled INVESTING THROUGH A FINANCIAL INTERMEDIARY. Shares of the A Class are subject to an initial sales charge, which declines as the amount of the purchase increases pursuant to the schedule set forth in the prospectus. This charge may be waived in the following situations due to sales efficiencies and competitive considerations: * Employer-sponsored retirement plan purchases * Certain individual retirement account rollovers * Purchases by registered representatives and other employees of certain financial intermediaries (and their immediate family members) having sales agreements with the advisor or the distributor * Wrap accounts maintained for clients of certain financial intermediaries who have entered into agreements with American Century * Purchases by current and retired employees of American Century and their immediate family members (spouses and children under age 21) and trusts or employer-sponsored retirement plans established by those persons * Purchases by certain other investors that American Century deems appropriate, including but not limited to current or retired directors, trustees and officers of funds managed by the advisor and trusts and employer-sponsored retirement plans established by those persons There are several ways to reduce the sales charges applicable to a purchase of A Class shares. These methods are described in the relevant prospectuses. You or your financial advisor must indicate at the time of purchase that you intend to take advantage of one of these reductions. Shares of the A, B and C Classes are subject to a contingent deferred sales charge (CDSC) upon redemption of the shares in certain circumstances. The specific ------ 88 charges and when they apply are described in the relevant prospectuses. The CDSC may be waived for certain redemptions by some shareholders, as described in the prospectuses. An investor may terminate his relationship with an intermediary at any time. If the investor does not establish a relationship with a new intermediary and transfer any accounts to that new intermediary, such accounts may be exchanged to the Investor Class of the fund, if such class is available. The investor will be the shareholder of record of such accounts. In this situation, any applicable CDSCs will be charged when the exchange is made. The aggregate CDSCs paid to the distributor for the A Class shares in the fiscal year ended October 31, 2007, were Mid Cap Growth, $22; Select, $32 and Small Cap Growth, $65. The aggregate CDSCs paid to the distributor for the B Class shares in the fiscal year ended October 31, 2007, were Capital Growth, $3,815; Fundamental Equity, $5,538; Select, $8,893; Mid Cap Growth, $5,166; Small Cap Growth, $10,988 and New Opportunities II, $10,468. The aggregate CDSCs paid to the distributor for the C Class shares in the fiscal year ended October 31, 2007 were Growth, $761; Select, $42; Vista, $705; Capital Growth, $246; Fundamental Equity, $2,906; New Opportunities II, $1,997; Ultra; $513; Heritage, $2,732; Mid Cap Growth, $174 and Small Cap Growth, $48. Payments to Dealers The funds' distributor expects to pay sales commissions to the financial intermediaries who sell A, B and/or C Class shares of the funds at the time of such sales. Payments for A Class shares will be as follows: PURCHASE AMOUNT DEALER CONCESSION -------------------------------------------------------------------------------- LESS THAN $50,000 5.00% -------------------------------------------------------------------------------- $50,000 - $99,999 4.00% -------------------------------------------------------------------------------- $100,000 - $249,999 3.25% -------------------------------------------------------------------------------- $250,000 - $499,999 2.00% -------------------------------------------------------------------------------- $500,000 - $999,999 1.75% -------------------------------------------------------------------------------- $1,000,000 - $3,999,999 1.00% -------------------------------------------------------------------------------- $4,000,000 - $9,999,999 0.50% -------------------------------------------------------------------------------- GREATER THAN $10,000,000 0.25% -------------------------------------------------------------------------------- No concession will be paid on purchases by employer-sponsored retirement plans. Payments will equal 4.00% of the purchase price of B Class shares and 1.00% of the purchase price of the C Class shares sold by the intermediary. The distributor will retain the 12b-1 fee paid by the C Class of funds for the first 12 months after the shares are purchased. This fee is intended in part to permit the distributor to recoup a portion of on-going sales commissions to dealers plus financing costs, if any. Beginning with the first day of the 13th month, the distributor will make the C Class distribution and individual shareholder services fee payments described above to the financial intermediaries involved on a quarterly basis. In addition, B and C Class purchases and A Class purchases greater than $1,000,000 are subject to a CDSC as described in the prospectuses. From time to time, the distributor may provide additional payments to dealers, including but not limited to payment assistance for conferences and seminars, provision of sales or training programs for dealer employees and/or the public (including, in some cases, payment for travel expenses for registered representatives and other dealer employees who participate), advertising and sales campaigns about a fund or funds, and assistance in financing dealer-sponsored ------ 89 events. Other payments may be offered as well, and all such payments will be consistent with applicable law, including the then-current rules of the Financial Industry Regulatory Authority (FINRA). Such payments will not change the price paid by investors for shares of the funds. BUYING AND SELLING FUND SHARES Information about buying, selling, exchanging and, if applicable, converting fund shares is contained in the funds' prospectuses. The prospectuses are available to investors without charge and may be obtained by calling us.

(4) ACCOUNTS ESTABLISHED PRIOR TO AUGUST 1, 2006, MAY MAKE ADDITIONAL PURCHASES. ------ 90 VALUATION OF A FUND'S SECURITIES All classes of the funds except the A Class are offered at their net asset value, as described below. The A Class of the funds are offered at their public offering price, which is the net asset value plus the appropriate sales charge. This calculation may be expressed as a formula: Offering Price = Net Asset Value/(1 - Sales Charge as a % of Offering Price) For example, if the net asset value of a fund's A Class shares is $5.00, the public offering price would be $5/(1-5.75%) = $5.31. Each fund's net asset value per share (NAV) is calculated as of the close of business of the New York Stock Exchange (the NYSE) each day the NYSE is open for business. The NYSE usually closes at 4 p.m. Eastern time. The NYSE typically observes the following holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect the same holidays to be observed in the future, the NYSE may modify its holiday schedule at any time. Each fund's NAV is calculated by adding the value of all portfolio securities and other assets, deducting liabilities and dividing the result by the number of shares outstanding. Expenses and interest earned on portfolio securities are accrued daily. The portfolio securities of each fund that are listed or traded on a domestic securities exchange are valued at the last sale price on that exchange, except as otherwise noted. Portfolio securities primarily traded on foreign securities exchanges generally are valued at the preceding closing values of such securities on the exchange where primarily traded. If no sale is reported, or if local convention or regulation so provides, the mean of the latest bid and asked prices is used. Depending on local convention or regulation, securities traded over-the-counter are priced at the mean of the latest bid and asked prices, the last sale price, or the official closing price. When market quotations are not readily available, securities and other assets are valued at fair value as determined in accordance with procedures adopted by the Board of Directors. Debt securities not traded on a principal securities exchange are valued through valuations obtained from a commercial pricing service or at the most recent mean of the bid and asked prices provided by investment dealers in accordance with procedures established by the Board of Directors. Because there are hundreds of thousands of municipal issues outstanding, and the majority of them do not trade daily, the prices provided by pricing services for these types of securities are generally determined without regard to bid or last sale prices. In valuing securities, the pricing services generally take into account institutional trading activity, trading in similar groups of securities, and any developments related to specific securities. The methods used by the pricing service and the valuations so established are reviewed by the advisor under the general supervision of the Board of Directors. There are a number of pricing services available, and the advisor, on the basis of ongoing evaluation of these services, may use other pricing services or discontinue the use of any pricing service in whole or in part. Securities maturing within 60 days of the valuation date may be valued at cost, plus or minus any amortized discount or premium, unless the directors determine that this would not result in fair valuation of a given security. Other assets and securities for which quotations are not readily available are valued in good faith using methods approved by the Board of Directors. The value of an exchange-traded foreign security is determined in its national currency as of the close of trading on the foreign exchange on which it is traded or as of the close of business on the NYSE, if that is earlier. That value is then translated to dollars at the prevailing foreign exchange rate. ------ 91 Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day that the NYSE is open. If an event were to occur after the value of a security was established, but before the net asset value per share was determined, that was likely to materially change the net asset value, then that security would be valued as determined in accordance with procedures adopted by the Board of Directors. Trading of these securities in foreign markets may not take place on every day that the NYSE is open. In addition, trading may take place in various foreign markets and on some electronic trading networks on Saturdays or on other days when the NYSE is not open and on which the funds' net asset values are not calculated. Therefore, such calculations do not take place contemporaneously with the determination of the prices of many of the portfolio securities used in such calculation, and the value of the funds' portfolios may be affected on days when shares of the funds may not be purchased or redeemed. TAXES FEDERAL INCOME TAX Each fund intends to qualify annually as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). By so qualifying, a fund should be exempt from federal income taxes to the extent that it distributes substantially all of its net investment income and net realized capital gains (if any) to investors. If a fund fails to qualify as a regulated investment company, it will be liable for taxes, significantly reducing its distributions to investors and eliminating investors' ability to treat distributions received from the funds in the same manner in which they were realized by the funds. If fund shares are purchased through taxable accounts, distributions of net investment income and net short-term capital gains are taxable to you as ordinary income, unless they are designated as qualified dividend income and you meet a minimum required holding period with respect to your shares of a fund, in which case such distributions are taxed as long-term capital gains. Qualified dividend income is a dividend received by a fund from the stock of a domestic or qualifying foreign corporation, provided that the fund has held the stock for a required holding period. The required holding period for qualified dividend income is met if the underlying shares are held more than 60 days in the 121-day period beginning 60 days prior to the ex-dividend date. Dividends received by the funds on shares of stock of domestic corporations may qualify for the 70% dividends-received deduction to the extent that the fund held those shares for more than 45 days. Distributions from gains on assets held by the funds longer than 12 months are taxable as long-term gains regardless of the length of time you have held your shares in the fund. If you purchase shares in the fund and sell them at a loss within six months, your loss on the sale of those shares will be treated as a long-term capital loss to the extent of any long-term capital gains dividend you received on those shares. Dividends and interest received by a fund on foreign securities may give rise to withholding and other taxes imposed by foreign countries. However, tax conventions between certain countries and the United States may reduce or eliminate such taxes. Foreign countries generally do not impose taxes on capital gains with respect to investments by non-resident investors. Any foreign taxes paid by a fund will reduce its dividend distributions to investors. ------ 92 If more than 50% of the value of a fund's total assets at the end of its fiscal year consists of securities of foreign corporations, the fund may qualify for and make an election with the Internal Revenue Service with respect to such fiscal year so that fund shareholders may be able to claim a foreign tax credit in lieu of a deduction for foreign income taxes paid by the fund. If such an election is made, the foreign taxes paid by the fund will be treated as income received by you. In order for you to utilize the foreign tax credit, you must have held your shares for 16 days or more during the 31-day period, beginning 15 days prior to the ex-dividend date for the mutual fund shares. The mutual fund must meet a similar holding period requirement with respect to foreign securities to which a dividend is attributable. Any portion of the foreign tax credit that is ineligible as a result of the fund not meeting the holding period requirement will be deducted in computing net investment income. If a fund purchases the securities of certain foreign investment funds or trusts called passive foreign investment companies (PFIC), capital gains on the sale of such holdings will be deemed ordinary income regardless of how long the fund holds the investment. The fund also may be subject to corporate income tax and an interest charge on certain dividends and capital gains earned from these investments, regardless of whether such income and gains are distributed to shareholders. In the alternative, the fund may elect to recognize cumulative gains on such investments as of the last day of its fiscal year and distribute them to shareholders. Any distribution attributable to a PFIC is characterized as ordinary income. As of October 31, 2007, the funds in the table below had the following capital loss carryovers. When a fund has a capital loss carryover, it does not make capital gains distributions until the loss has been offset or expired.

Those regulations require you to certify that the Social Security number or tax identification number you provide is correct and that you are not subject to withholding for previous under-reporting to the IRS. You will be asked to make the appropriate certification on your account application. Payments reported by us to the IRS that omit your Social Security number or tax identification number will subject us to a non-refundable penalty of $50, which will be charged against your account if you fail to provide the certification by the time the report is filed. A redemption of shares of a fund (including a redemption made in an exchange transaction) will be a taxable transaction for federal income tax purposes and you generally will recognize gain or loss in an amount equal to the difference between the basis of the shares and the amount received. If a loss is realized on the redemption of fund shares, the reinvestment in additional fund shares within 30 days before or after the redemption may be subject to the "wash sale" rules of the Code, resulting in a postponement of the recognition of such loss for federal income tax purposes. STATE AND LOCAL TAXES Distributions by the funds also may be subject to state and local taxes, even if all or a substantial part of such distributions are derived from interest on U.S. government obligations which, if you received such interest directly, would be exempt from state income tax. However, most but not all states allow this tax exemption to pass through to fund shareholders when a fund pays distributions to its shareholders. You should consult your tax advisor about the tax status of such distributions in your state. The information above is only a summary of some of the tax considerations affecting the funds and their shareholders. No attempt has been made to discuss individual tax consequences. A prospective investor should consult with his or her tax advisors or state or local tax authorities to determine whether the funds are suitable investments.

Those investments, however, are subject to certain credit quality restrictions, as noted in the prospectuses. The following is a summary of the rating categories referenced in the prospectus. RATINGS OF CORPORATE DEBT SECURITIES -------------------------------------------------------------------------------- Standard & Poor's -------------------------------------------------------------------------------- AAA This is the highest rating assigned by S&P to a debt obligation. It indicates an extremely strong capacity to pay interest and repay principal. -------------------------------------------------------------------------------- AA Debt rated in this category is considered to have a very strong capacity to pay interest and repay principal. It differs from the highest-rated obligations only in small degree. -------------------------------------------------------------------------------- A Debt rated A has a strong capacity to pay interest and repay principal, although it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher-rated categories. -------------------------------------------------------------------------------- BBB Debt rated in this category is regarded as having an adequate capacity to pay interest and repay principal. While it normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than in higher-rated categories. Debt rated below BBB is regarded as having significant speculative characteristics. -------------------------------------------------------------------------------- BB Debt rated in this category has less near-term vulnerability to default than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions that could lead to inadequate capacity to meet timely interest and principal payments. The BB rating also is used for debt subordinated to senior debt that is assigned an actual or implied BBB rating. -------------------------------------------------------------------------------- B Debt rated in this category is more vulnerable to nonpayment than obligations rated BB, but currently has the capacity to pay interest and repay principal. Adverse business, financial, or economic conditions will likely impair the obligor's capacity or willingness to pay interest and repay principal. -------------------------------------------------------------------------------- CCC Debt rated in this category is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial, or economic conditions, it is not likely to have the capacity to pay interest and repay principal. The CCC rating category is also used for debt subordinated to senior debt that is assigned an actual or implied B or B- rating. -------------------------------------------------------------------------------- CC Debt rated in this category is currently highly vulnerable to nonpayment. This rating category is also applied to debt subordinated to senior debt that is assigned an actual or implied CCC rating. -------------------------------------------------------------------------------- C The rating C typically is applied to debt subordinated to senior debt, and is currently highly vulnerable to nonpayment of interest and principal. This rating may be used to cover a situation where a bankruptcy petition has been filed or similar action taken, but debt service payments are being continued. -------------------------------------------------------------------------------- D Debt rated in this category is in default. This rating is used when interest payments or principal repayments are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. It also will be used upon the filing of a bankruptcy petition or the taking of a similar action if debt service payments are jeopardized. -------------------------------------------------------------------------------- ------ 95 Moody's Investors Service, Inc. -------------------------------------------------------------------------------- Aaa This is the highest rating assigned by Moody's to a debt obligation. It indicates an extremely strong capacity to pay interest and repay principal. -------------------------------------------------------------------------------- Aa Debt rated in this category is considered to have a very strong capacity to pay interest and repay principal and differs from Aaa issues only in a small degree. Together with Aaa debt, it comprises what are generally known as high-grade bonds. -------------------------------------------------------------------------------- A Debt rated in this category possesses many favorable investment attributes and is to be considered as upper- medium-grade debt. Although capacity to pay interest and repay principal are considered adequate, it is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than debt in higher-rated categories. -------------------------------------------------------------------------------- Baa Debt rated in this category is considered as medium- grade debt having an adequate capacity to pay interest and repay principal. While it normally exhibits adequate protection parameters, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for debt in this category than in higher-rated categories. Debt rated below Baa is regarded as having significant speculative characteristics. -------------------------------------------------------------------------------- Ba Debt rated Ba has less near-term vulnerability to default than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions that could lead to inadequate capacity to meet timely interest and principal payments. Often the protection of interest and principal payments may be very moderate. -------------------------------------------------------------------------------- B Debt rated B has a greater vulnerability to default, but currently has the capacity to meet financial commitments. Assurance of interest and principal payments or of maintenance of other terms of the contract over any long period of time may be small. The B rating category is also used for debt subordinated to senior debt that is assigned an actual or implied Ba or Ba3 rating. -------------------------------------------------------------------------------- Caa Debt rated Caa is of poor standing, has a currently identifiable vulnerability to default, and is dependent upon favorable business, financial and economic conditions to meet timely payment of interest and repayment of principal. In the event of adverse business, financial or economic conditions, it is not likely to have the capacity to pay interest and repay principal. Such issues may be in default or there may be present elements of danger with respect to principal or interest. The Caa rating is also used for debt subordinated to senior debt that is assigned an actual or implied B or B3 rating. -------------------------------------------------------------------------------- Ca Debt rated in this category represent obligations that are speculative in a high degree. Such debt is often in default or has other marked shortcomings. -------------------------------------------------------------------------------- C This is the lowest rating assigned by Moody's, and debt rated C can be regarded as having extremely poor prospects of attaining investment standing. -------------------------------------------------------------------------------- Fitch Investors Service, Inc. -------------------------------------------------------------------------------- AAA Debt rated in this category has the lowest expectation of credit risk. Capacity for timely payment of financial commitments is exceptionally strong and highly unlikely to be adversely affected by foreseeable events. -------------------------------------------------------------------------------- AA Debt rated in this category has a very low expectation of credit risk. Capacity for timely payment of financial commitments is very strong and not significantly vulnerable to foreseeable events. -------------------------------------------------------------------------------- A Debt rated in this category has a low expectation of credit risk. Capacity for timely payment of financial commitments is strong, but may be more vulnerable to changes in circumstances or in economic conditions than debt rated in higher categories. -------------------------------------------------------------------------------- BBB Debt rated in this category currently has a low expectation of credit risk and an adequate capacity for timely payment of financial commitments. However, adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category. -------------------------------------------------------------------------------- BB Debt rated in this category has a possibility of developing credit risk, particularly as the result of adverse economic change over time. However, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment-grade. -------------------------------------------------------------------------------- ------ 96 Fitch Investors Service, Inc. -------------------------------------------------------------------------------- B Debt rated in this category has significant credit risk, but a limited margin of safety remains. Financial commitments currently are being met, but capacity for continued debt service payments is contingent upon a sustained, favorable business and economic environment. -------------------------------------------------------------------------------- CCC, CC, C Debt rated in these categories has a real possibility for default. Capacity for meeting financial commitments depends solely upon sustained, favorable business or economic developments. A CC rating indicates that default of some kind appears probable; a C rating signals imminent default. -------------------------------------------------------------------------------- DDD, DD, D The ratings of obligations in these categories are based on their prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. DDD obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest. DD indicates potential recoveries in the range of 50%-90% and D the lowest recovery potential, i.e., below 50%. Entities rated in these categories have defaulted on some or all of their obligations. Entities rated DDD have the highest prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated DD and D are generally undergoing a formal reorganization or liquidation process; those rated DD are likely to satisfy a higher portion of their outstanding obligations, while entities rated D have a poor prospect of repaying all obligations. -------------------------------------------------------------------------------- To provide more detailed indications of credit quality, the Standard & Poor's ratings from AA to CCC may be modified by the addition of a plus or minus sign to show relative standing within these major rating categories. Similarly, Moody's adds numerical modifiers (1,2,3) to designate relative standing within its major bond rating categories. Fitch also rates bonds and uses a ratings system that is substantially similar to that used by Standard & Poor's. COMMERCIAL PAPER RATINGS -------------------------------------------------------------------------------- S&P MOODY'S DESCRIPTION -------------------------------------------------------------------------------- A-1 Prime-1 This indicates that the degree of safety (P-1) regarding timely payment is strong. Standard & Poor's rates those issues determined to possess extremely strong safety characteristics as A-1+. -------------------------------------------------------------------------------- A-2 Prime-2 Capacity for timely payment on (P-2) commercial paper is satisfactory, but the relative degree of safety is not as high as for issues designated A-1. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriated, may be more affected by external conditions. Ample alternate liquidity is maintained. -------------------------------------------------------------------------------- A-3 Prime-3 Satisfactory capacity for timely repayment. (P-3) Issues that carry this rating are somewhat more vulnerable to the adverse changes in circumstances than obligations carrying the higher designations. -------------------------------------------------------------------------------- NOTE RATINGS -------------------------------------------------------------------------------- S&P MOODY'S DESCRIPTION -------------------------------------------------------------------------------- SP-1 MIG-1; Notes are of the highest quality enjoying VMIG-1 strong protection from established cash flows of funds for their servicing or from established and broad-based access to the market for refinancing, or both. -------------------------------------------------------------------------------- SP-2 MIG-2; Notes are of high quality, with margins of VMIG-2 protection ample, although not so large as in the preceding group. -------------------------------------------------------------------------------- SP-3 MIG-3; Notes are of favorable quality, with all VMIG-3 security elements accounted for, but lacking the undeniable strength of the preceding grades. Market access for refinancing, in particular, is likely to be less well established. -------------------------------------------------------------------------------- SP-4 MIG-4; Notes are of adequate quality, carrying VMIG-4 specific risk but having protection and not distinctly or predominantly speculative. -------------------------------------------------------------------------------- ------ 97 MORE INFORMATION ABOUT THE FUNDS IS CONTAINED IN THESE DOCUMENTS Annual and Semiannual Reports Annual and semiannual reports contain more information about the funds' investments and the market conditions and investment strategies that significantly affected the funds' performance during the most recent fiscal period.

                 AS AMENDED AND RESTATED AS OF NOVEMBER 29, 2007

                                     OFFICES

     SECTION 1. The registered  office shall be in the City of Baltimore,  State
of Maryland.

     SECTION 2. The  Corporation may also have offices at such other places both
within and without the State of Maryland as the Board of Directors may from time
to time determine or the business of the Corporation may require.

                            MEETINGS OF STOCKHOLDERS

     SECTION 3. Meetings of the stockholders  shall be held at the office of the
Corporation  in Kansas  City,  Missouri or at any other place  within the United
States as shall be  designated  from time to time by the Board of Directors  and
stated in the notice of meeting.

     SECTION 4. The Corporation  shall not be required to hold an annual meeting
of its  stockholders  in any year in which  the  election  of  Directors  is not
required by the  Investment  Company Act of 1940,  as amended  (the  "Investment
Company  Act"),  to be acted upon by the holders of any class or series of stock
of the  Corporation.  The use of the term "annual  meeting,"  wherever  found in
these By-laws,  shall not be construed to imply a requirement that a stockholder
meeting be held annually. In the event that the Corporation shall be required by
the Investment  Company Act to hold an annual meeting of  stockholders  to elect
Directors,  such  meeting  shall be held at a date and time set by the  Board of
Directors in accordance  with the Investment  Company Act (but in no event later
than 120 days  after the  occurrence  of the event  requiring  the  election  of
Directors).  Any annual meeting that is not required by the  Investment  Company
Act shall be held on a date and time  during  the month of July set by the Board
of Directors.  At any annual meeting,  the  stockholders  shall elect a Board of
Directors  and may transact any business  within the powers of the  Corporation.
Any business of the  Corporation  may be transacted at an annual meeting without
being  specially   designated  in  the  notice,   except  such  business  as  is
specifically required by statute to be stated in the notice.

     SECTION 5. A majority of the stock issued and  outstanding  and entitled to
vote at any meeting of stockholders,  the holders of which are present in person
or  represented  by proxy,  shall  constitute  a quorum for the  transaction  of
business, except as otherwise provided by law, by the Articles of Incorporation,
or by these By-laws.  Where the approval of any  particular  item of business to
come  before a meeting  requires  the  approval of one or more than one class or
series of stock,  voting  separately,  the holders of a majority of each of such
classes or series  entitled to be voted must be present to  constitute  a quorum
for the transaction of such item of business. If, however, a quorum shall not be
present or  represented  at any meeting of the  stockholders,  a majority of the
voting stock represented in person or by proxy may adjourn the meeting from time
to time,  without notice other than announcement at the meeting,  until a quorum
shall be




AMERICAN CENTURY MUTUAL FUNDS, INC.                                       BYLAWS
--------------------------------------------------------------------------------


present or  represented.  At such  adjourned  meeting at which a quorum shall be
present or  represented,  any business may be  transacted  which might have been
transacted at the meeting as originally notified. If the adjournment is for more
than 90 days,  or if after the  adjournment  a new record  date is fixed for the
adjourned  meeting,  a notice of the  adjourned  meeting  shall be given to each
stockholder of record entitled to vote thereat.

     SECTION 6. When a quorum is present at any  meeting,  a majority of all the
votes cast is sufficient to approve any matter which  properly  comes before the
meeting,  unless a different  vote for such matter is  specified  by law, by the
Articles of  Incorporation  or by these  By-laws,  in which case such  different
specified vote shall be required to approve such matter.

     SECTION 7. Special  meetings of the  stockholders may be called at any time
by the Board of Directors,  or by the Chairman of the Board,  the  President,  a
Vice President, the Secretary or an Assistant Secretary.

     SECTION 8.  Special  meetings  of the  stockholders  shall be called by the
Secretary  upon  written  request of  stockholders  entitled to cast at least 25
percent of all the votes entitled to be cast at such meeting. Such request shall
state the  purpose or purposes  of such  meeting and the matters  proposed to be
acted on thereat.  After  verification of the  sufficiency of such request,  the
Secretary  shall  then  inform the  requesting  stockholders  of the  reasonably
estimated cost of preparing and mailing such notice of the meeting. Upon payment
to the  Corporation  of such costs the Secretary  shall give notice  stating the
purpose or  purposes of the  meeting to all  stockholders  entitled to notice of
such meeting;  provided,  however,  unless requested by stockholders entitled to
cast a majority of all the votes entitled to be cast at the meeting,  no special
meeting need be called to consider any matter which is substantially the same as
a matter voted upon at any special meeting of the  stockholders  held during the
preceding 12 months.

     SECTION 9. Not less than ten nor more than 90 days before the date of every
stockholders'  meeting, the Secretary shall give to each stockholder entitled to
vote at such  meeting,  and to each  stockholder  not  entitled  to vote  who is
entitled by statute to notice,  written or printed  notice  stating (i) the time
and place of the meeting and, (ii) the purpose or purposes for which the meeting
is called if the  meeting is a special  meeting,  or if notice of the purpose of
the  meeting is  required  by statute to be given.  Such  notice  shall be given
either by mail or by presenting it to the  stockholder  personally or by leaving
it at his residence or usual place of business.  If mailed, such notice shall be
deemed to be given when  deposited  in the United  States mail  addressed to the
stockholder at his address as it appears on the records of the Corporation, with
postage thereon prepaid.

     SECTION 10.  Business  transacted  at any special  meeting of  stockholders
shall be limited to the purposes stated in the notice of the meeting.

     SECTION 11. At all meetings of  stockholders,  a  stockholder  may vote the
shares owned of record by him on the record date  (determined in accordance with
Section 42 hereof) for each such  stockholders'  meeting  either in person or by
written   proxy   signed  by  the   stockholder   or  by  his  duly   authorized
attorney-in-fact.  No proxy shall be valid after 11 months from its date, unless
otherwise  provided in the proxy.  At all meetings of  stockholders,  unless the
voting is

conducted by inspectors,  all questions relating to the qualifications of voters
and the  validity of proxies and the  acceptance  or rejection of votes shall be
decided by the chairman of the meeting.

                                    DIRECTORS

     SECTION 12. The number of Directors of the  Corporation  shall be seven. By
vote of a majority of the entire  Board of  Directors,  the number of  Directors
fixed by the Articles of  Incorporation  or by these By-laws may be increased or
decreased  from time to time to a number not  exceeding  15 nor less than three,
but the tenure of office of a Director  shall not be affected by any decrease in
the number of Directors so made by the Board.  Until the first annual meeting of
stockholders or until  successors are duly elected and qualify,  the Board shall
consist of the persons  named as such in the Articles of  Incorporation.  At the
first annual meeting of stockholders and at each annual meeting thereafter,  the
stockholders  shall elect Directors to hold office until the next annual meeting
or until their successors are elected and qualify.  A plurality of all the votes
cast at an annual  meeting at which a quorum is  present  shall be  required  to
elect  Directors of the  Corporation.  Each Director,  upon his election,  shall
qualify by  accepting  the Office of  Director,  and his  attendance  at, or his

("Indemnitee") who is a present or former director,  officer, employee, or agent
of the Corporation, or who, while a director, officer, employee, or agent of the
Corporation,  is or was serving at the request of the Corporation as a director,
officer,  partner,  trustee,  employee  or agent of another  foreign or domestic
corporation,  partnership,  joint venture,  trust,  other enterprise or employee
benefit plan who, by reason of his position was, is, or is threatened to be made
a party to any threatened,  pending,  or completed  action,  suit or proceeding,
whether  civil,   criminal,   administrative,   or  investigative   (hereinafter
collectively  referred to as a "Proceeding")  against any judgments,  penalties,
fines,  amounts paid in settlement,  and expenses  (including  attorneys'  fees)
actually and  reasonably  incurred by such  Indemnitee  in  connection  with any
Proceeding,  to the fullest extent that such indemnification may be lawful under
Maryland law. The Corporation  shall pay any reasonable  expenses so incurred by
such  Indemnitee in defending a Proceeding  in advance of the final  disposition
thereof to the fullest  extent  that such  advance  payment may be lawful  under
Maryland law.  Subject to any applicable  limitations and requirements set forth
in the Corporation's Articles of Incorporation and in these By-laws, any payment
of  indemnification  or advance of expenses shall be made in accordance with the
procedures set forth in Maryland law.

     (b) Anything in this Section 51 to the contrary notwithstanding, nothing in
this Section 51 shall protect or purport to protect any  Indemnitee  against any
liability to the

Corporation or its  stockholders,  whether or not there has been an adjudication
of  liability,  to which he would  otherwise  be  subject  by reason of  willful
misfeasance,  bad faith,  gross negligence,  or reckless disregard of the duties
involved in the conduct of his office ("Disabling Conduct").

     (c)  Anything  in  this  Section  51 to the  contrary  notwithstanding,  no
indemnification shall be made by the Corporation to any Indemnitee unless:

          (i)  there is a final  decision on the merits by a court or other body
               before whom the  Proceeding  was brought that the  Indemnitee was
               not liable by reason of Disabling Conduct; or

          (ii) in the absence of such a  decision,  the  Corporation's  Board of
               Directors,  based upon a review of the facts,  forms a reasonable
               belief that the  Indemnitee was not liable by reason of Disabling
               Conduct, which reasonable belief may be formed:

               (A)  by the vote of a majority of a quorum of  directors  who are
                    neither  "interested  persons" of the Corporation as defined
                    in Section  2(a)(19)  of the  Investment  Company  Act,  nor
                    parties to the Proceeding; or

               (B)  based on a written opinion of independent legal counsel.

     (d)  Anything  in this  Section  51 to the  contrary  notwithstanding,  any
advance of expenses by the Corporation to any Indemnitee shall be made only upon
the  undertaking by such Indemnitee to repay the advance unless it is ultimately
determined  that  such  Indemnitee  is  entitled  to  indemnification  as  above
provided, and only if one of the Corporation's Board of Directors:

          (i)  obtains  assurances  that the  advance  will be repaid by (A) the
               Corporation  receiving  collateral  from the  Indemnitee  for his
               undertaking or (B) the Corporation  obtaining  insurance  against
               losses by reason of any lawful advances;; or

          (ii) has a reasonable  belief that the  Indemnitee  has not engaged in
               Disabling  Conduct  and  will  ultimately  be found  entitled  to
               indemnification, which reasonable belief may be formed:

               (A)  by a  majority  of a quorum  of  directors  who are  neither
                    "interested  persons"  of  the  Corporation  as  defined  in
                    Section 2(a)(19) of the Investment  Company Act, nor parties
                    to the Proceeding; or

               (B)  based upon a written opinion of an independent legal counsel
                    that  in  turn is  based  on  counsel's  review  of  readily
                    available  facts  (which  review  shall  not  require a full
                    trial-type inquiry).

     (e) The indemnification and advancement of expenses provided by, or granted
pursuant to, this  Section 51 shall not be deemed  exclusive of any other rights
to which  those  seeking  indemnification  or  advancement  of  expenses  may be
entitled under any law, bylaw, agreement,  vote of stockholders or disinterested
directors or otherwise, both as to action in such person's official capacity and
as to action in another capacity while holding such office.

     (f) The indemnification and advancement of expenses provided by, or granted
pursuant to, this Section 51 shall, unless otherwise provided when authorized or
ratified, continue as to an Indemnitee who has ceased to be a director, officer,
employee  or agent and shall inure to the  benefit of the heirs,  executors  and
administrators of such an Indemnitee.

     (g) For purposes of this Section 51,  references  to (i) the  "Corporation"
shall  include,  in  addition  to the  resulting  corporation,  any  constituent
corporation   (including  any  constituent  of  a  constituent)  absorbed  in  a
consolidation  or merger which, if its separate  existence had continued,  would
have had power and authority to indemnify its directors, officers, and employees
or agents so that any  person who is or was a  director,  officer,  employee  or
agent of such  constituent  corporation,  or is or was serving at the request of
such  constituent  corporation  as a  director,  officer,  employee  or agent of
another trust,  partnership,  joint venture,  trust or other  enterprise,  shall
stand in the same position  under the provisions of this Section 51 with respect
to the resulting or surviving corporation as such person would have with respect
to such constituent  corporation if its separate  existence had continued;  (ii)
"fines" shall  include any excise taxes  assessed on a person with respect to an
employee  benefit plan;  and (iii)  "serving at the request of the  Corporation"
shall  include  any  service as a  director,  officer,  employee or agent of the
Corporation  which  imposes  duties on, or involves  service by, such  director,
officer,  employee  or agent  with  respect to an  employee  benefit  plan,  its
participants or beneficiaries.

     (h) This Section 51 does not apply to any  proceeding  against any trustee,
investment  manager  or other  fiduciary  of an  employee  benefit  plan in that
person's  capacity as such, even though that person may also be an agent of this
Corporation as defined in Subsection  (a) of this Section 51. Nothing  contained
in this  Section  51 shall  limit any right to  indemnification  to which such a
director,  investment  manager or other fiduciary may be entitled by contract or
otherwise  which shall be enforceable to the extent  permitted by applicable law
other than this Section 51.

     SECTION 52. To the fullest extent permitted by applicable  Maryland law and
by Sections  17(h) and 17(i) of the  Investment  Company  Act, or any  successor
provisions thereto or interpretations  thereunder,  the Corporation may purchase
and  maintain  insurance  on  behalf  of any  person  who is or was a  director,
officer, employee, or agent of the Corporation,  or who is or was serving at the
request of the Corporation as a director,  officer, partner, trustee,  employee,
or agent of another foreign or domestic corporation, partnership, joint venture,
trust,  other  enterprise,  or employee  benefit  plan,  against  any  liability
asserted  against him and incurred by him in any such capacity or arising out of
his position,  whether or not the Corporation  would have the power to indemnify
him against such  liability  pursuant to Section  2-418 of the Maryland  General
Corporation Law.

Investment  Management,  Inc.  (each  referred  to herein as the  "Advisor,"  as
applicable),  or both for the provision of investment  advisory  services by the
Advisor to the Issuer;

     WHEREAS,  the Boards of  Directors  of the Issuer (the  "Board")  wishes to
engage the  Distributor to act as the distributor of the shares of each class of
the  Issuer's  separate  series,  and any other  series  and  classes  as may be
designated  from time to time hereafter (the  "Funds"),  in accordance  with the
terms of this Agreement.

     NOW,  THEREFORE,  in consideration of the mutual promises set forth herein,
the parties agree as follows:

SECTION 1. GENERAL RESPONSIBILITIES

Issuer hereby engages Distributor to act as exclusive  distributor of the shares
of each class of the Funds.  The Funds subject to this  Agreement as of the date
hereof are  identified  on SCHEDULE A, which may be amended from time to time in
accordance with SECTION 11 below. Sales of a Fund's shares shall be made only to
investors  residing  in those  states in which  such Fund is  registered.  After
effectiveness  of each  Fund's  registration  statement,  Distributor  will hold
itself  available to receive,  as agent for the Fund,  and will receive by mail,
telex, telephone, or such other method as may be agreed upon between Distributor
and Issuer,  orders for the purchase of Fund  shares,  and will accept or reject
such  orders on  behalf of the Fund in  accordance  with the  provisions  of the
applicable Fund's prospectus.  Distributor will be available to transmit orders,
as promptly as possible  after it accepts  such orders,  to the Fund's  transfer
agent  for  processing  at the  shares'  net  asset  value  next  determined  in
accordance with the prospectuses.




     a. OFFERING  PRICE.  All shares sold by  Distributor  under this  Agreement
shall be sold at the net asset value per share ("Net Asset Value") determined in
the manner described in each Fund's  prospectus,  as it may be amended from time
to time,  next computed  after the order is accepted by  Distributor,  or one or
more of its  affiliates  or  designees.  Each Fund shall  determine and promptly
furnish to  Distributor  a statement of the Net Asset Value of each class of the
Fund's  shares  at least  once each day that the Fund is open for  business,  as
described in its current prospectus.

     b. PROMOTION  SUPPORT.  Each Fund shall furnish to  Distributor  for use in
connection with the sale of its shares such written  information with respect to
said Fund as  Distributor  may  reasonably  request.  Each Fund  represents  and
warrants that such  information,  when  authenticated by the signature of one of
its  officers,  shall be true and  correct.  Each Fund  shall  also  furnish  to
Distributor  copies  of its  reports  to its  shareholders  and such  additional
information  regarding  said  Fund's  financial  condition  as  Distributor  may
reasonably request.  Any and all  representations,  statements and solicitations
respecting a Fund's shares made in advertisements,  sales literature, and in any
other manner  whatsoever  shall be limited to and conform in all respects to the
information provided hereunder.

     c. REGULATORY COMPLIANCE.  Each Fund shall furnish to Distributor copies of
its  current  form of  prospectus,  as filed with the SEC,  in such  quantity as
Distributor may reasonably request from time to time, and authorize  Distributor
to use the  prospectus in connection  with the sale of such Fund's  shares.  All
such sales shall be initiated by offer of, and  conducted  in  accordance  with,
such  prospectus  and all of the  provisions of the  Securities Act of 1933, the
Investment  Company Act of 1940 ("1940  Act") and all the rules and  regulations
promulgated  thereunder.  Distributor shall furnish applicable federal and state
regulatory  authorities  with any information or reports related to its services
under this  Agreement  that such  authorities  may lawfully  request in order to
ascertain  whether  the  Funds'  operations  are  being  conducted  in a  manner
consistent with any applicable law or regulations.

     d.  ACCEPTANCE.  All orders for the  purchase  of its shares are subject to
acceptance by each Fund.

SECTION 2. COMPENSATION

     a. INVESTOR CLASS AND INSTITUTIONAL CLASS OF SHARES.  Distributor shall not
be entitled to  compensation  for its  services  hereunder  with  respect to the
Investor Class and Institutional Class of shares.

     b. ADVISOR CLASS, A CLASS, B CLASS, C CLASS, AND R CLASS OF SHARES. For the
services  provided  and  expenses  incurred by  Distributor  as described in the
Master  Distribution  and  Shareholder  Services  Plan adopted by the Board with
respect  to the  Advisor  Class,  and the  Master  Distribution  and  Individual
Shareholder Services Plan with respect to each of the A Class, B Class, C Class,
and R Class of each Fund (the "12b-1 Plan"), as applicable, Distributor shall be
compensated by the Fund's Advisor, not by the Fund.


                                       2


SECTION 3. EXPENSES

     a.  Distributor,  or one or more of its affiliates or designees,  shall pay
all  expenses  incurred  by  it  in  connection  with  the  performance  of  its
distribution duties hereunder and under the 12b-1 Plan for each applicable class
offered by a Fund that is subject to a 12b-1 Plan (the "Class"),  including, but
not limited to (A) payment of asset-based sales charges,  including  commission,
ongoing   commissions  and  other  payments  to  brokers,   dealers,   financial

fees",  as  contemplated  by the Rule 2830 of the Conduct  Rules of the National
Association of Securities  Dealers,  Inc.; and (N) such other  distribution  and
services  activities  as the  Issuer  determines  may be paid for by the  Issuer
pursuant to the terms of this Agreement and in accordance with Rule 12b-1 of the
1940 Act.

     b. In addition  to paying the above  expenses  with  respect to each Class,
Distributor,  or one or more  of its  affiliates  or  designees,  shall  pay all
expenses  incurred  with respect to the other classes of each Fund in connection
with their  registration  under the Securities Act of 1933 and the 1940 Act, the
qualification  of such shares for sale in each  jurisdiction  designated  by the
appropriate  Advisor,  the issue and  transfer  of such  shares  (including  the
expenses of  confirming  purchase and  redemption  orders and of  supplying  the
information,  prices  and other  data to be  furnished  by the Funds  under this
Agreement),  the  registration of Distributor as a broker,  and the registration
and  qualification  of  its  officers,   directors  and  representatives   under

its officers,  trustees, employees or representatives is or shall be an employee
of a Fund in connection with the performance of Distributor's  duties hereunder.
Distributor  shall  be  responsible  for its  own  conduct  and the  employment,
control,  compensation  and  conduct of its agents  and  employees,  and for any
injury  to such  agents  or  employees  or to  others  through  its  agents  and
employees.  Any obligations of Distributor  hereunder may be performed by one or
more of the Distributor's affiliates or designees.

SECTION 8. RENEWAL AND TERMINATION

     a. TERM AND ANNUAL  RENEWAL.  The term of this Agreement  shall be from the
date of its approval by the vote of a majority of the Board of each Issuer,  and
it shall  continue in effect from year to year  thereafter  only so long as such
continuance is specifically approved at least annually by the vote of a majority

date of this  Agreement  or  subsequently  formed,  SCHEDULE  A hereto  shall be
amended to reflect  the  addition of such New Fund and the  distribution  of the
shares  of such  new fund  shall  thereafter  be  covered  by the  terms of this
Agreement.  In the event that such New Fund issues  multiple  classes of shares,
SCHEDULE A hereto shall be amended,  as appropriate,  to reflect the addition of
each such  class of the New  Fund's  shares.  In the event that any of the Funds
listed on SCHEDULE A terminates its  registration as an investment  company,  or
otherwise ceases operations, SCHEDULE A shall be amended to reflect the deletion
of such Fund and all of its classes.

                                  ADVISOR CLASS

SECTION 1. DISTRIBUTION FEES

a.   DISTRIBUTION  FEE. For  purposes of paying  costs and expenses  incurred in
     providing  the  services  set forth in  SECTION 2 below,  the series of the
     Issuer  identified  on SCHEDULE A (the  "Funds")  shall pay the  investment

     daily net assets of the shares of the Funds'  Advisor  Class of shares (the
     "Distribution Fee").

b.   APPLICABILITY  TO NEW FUNDS. If the Issuer desires to add additional  funds
     to the Plan,  whether  currently  existing or created in the future (a "New
     Fund"),  and the Issuer's Board of Directors (the "Board") has approved the
     Plan for such New Fund as in the  manner  set  forth in  SECTION  4 of this
     Plan, as well as by the then-sole  shareholder  of the Advisor Class shares
     of such New Fund (if  required by the  Investment  Company Act of 1940 (the
     "1940  Act") or rules  promulgated  under the 1940  Act),  this Plan may be
     amended to provide that such New Fund will become  subject to this Plan and
     will pay the Distribution  Fee set forth in SECTION 1(A) above,  unless the
     Board  specifies  otherwise.  After the  adoption of this Plan by the Board
     with  respect  to the  Advisor  Class of shares  of the New Fund,  the term
     "Funds"  under this Plan  shall  thereafter  be deemed to include  such New
     Fund.

c.   CALCULATION  AND  ASSESSMENT.  Distribution  Fees  under  this Plan will be
     calculated  and accrued daily by each Fund and paid to the Advisor  monthly
     or at such other intervals as the Issuer and the Advisor may agree.

SECTION 2. DISTRIBUTION SERVICES

The Advisor  shall use the  Distribution  Fee set forth in SECTION  1(A) of this
Plan to pay for  services  in  connection  with  any  activities  undertaken  or
expenses incurred by the distributor of the Funds' shares (the "Distributor") or
its affiliates  primarily intended to result in the sale of Advisor Class shares
of the Funds,  which  services  may  include,  but are not  limited  to, (A) the
payment of sales commissions, ongoing commissions and other payments to brokers,
dealers,  financial  institutions or others who sell Advisor Class shares of the
Funds  pursuant  to  Selling   Agreements;   (B)   compensation   to  registered
representatives  or other  employees  of  Distributor  who  engage in or support

expenses  (including  overhead and  telephone  expenses)  of,  Distributor;  (D)
printing of prospectuses,  statements of additional  information and reports for
other than existing shareholders; (E) preparation,  printing and distribution of
sales literature and advertising  materials provided to the




Funds'  shareholders and prospective  shareholders;  (F) receiving and answering
correspondence   from   prospective    shareholders,    including   distributing
prospectuses, statements of additional information, and shareholder reports; (G)
provision of facilities to answer  questions from  prospective  investors  about
Fund shares;  (H) complying with federal and state securities laws pertaining to
the sale of Fund shares; (I) assisting investors in completing application forms
and  selecting  dividend  and other  account  options;  (J)  provision  of other
reasonable  assistance in connection with the  distribution of Fund shares;  (K)
organizing  and  conducting  of  sales  seminars  and  payments  in the  form of
transactional   compensation  or  promotional  incentives;  (L)  profit  on  the
foregoing;  and (M) such other distribution and service activities as the Issuer
determines may be paid for by the Issuer  pursuant to the terms of this Plan and
in accordance  with Rule 12b-1 of the 1940 Act;  provided that if the Securities
and Exchange  Commission  determines that any of the foregoing  services are not
permissible   under  Rule  12b-1,   any  payments  for  such   activities   will
automatically cease.

SECTION 3. INDIVIDUAL SHAREHOLDER SERVICES

Advisor may engage third parties to provide individual  shareholder  services to
the   shareholders  of  the  Advisor  Class  shares   ("Individual   Shareholder
Services").  The amount  set forth in  SECTION  1(A) of this Plan may be paid to
Advisor  for  expenses  incurred by it as a result of these  arrangements.  Such
Individual  Shareholder  Services and related  expenses relate to activities for
which  service  fees may be paid as  contemplated  by the  Conduct  Rules of the
Financial Industry Regulatory Authority ("FINRA"),  and may include, but are not
limited to, (A)  individualized  and customized  investment  advisory  services,
including the consideration of shareholder  profiles and specific goals; (B) the
creation  of  investment  models  and  asset  allocation  models  for use by the
shareholder  in selecting  appropriate  Funds;  (C)  proprietary  research about
investment  choices  and the market in  general;  (D)  periodic  rebalancing  of
shareholder  accounts to ensure  compliance with the selected asset  allocation;
(E) consolidation of shareholder accounts in one place; and (F) other individual
services; provided that if FINRA determines that any of the foregoing activities
are not permissible, any payment for such activities will automatically cease.

SECTION 4. EFFECTIVENESS

This Plan has been approved by the vote of both (a) the Board and (b) a majority
of those members of the Board who are not "interested persons" as defined in the
1940  Act  (the  "Independent  Members"),  and  initially  became  effective  on
September 3, 1996.

SECTION 5. TERM

This Plan will  continue  in full force and effect for a period of one year from
the date  hereof,  and for  successive  periods  of up to one  year  thereafter,
provided that each such  continuance is approved by a majority of (a) the Board,
and (b) the Independent Members.

SECTION 6. REPORTING REQUIREMENTS

The Advisor shall administer this Plan in accordance with Rule 12b-1 of the 1940

Members will review and approve in exercise of their fiduciary  duties, at least
quarterly,  a written  report of the  amounts  expended  under  this Plan by the
Advisor  with  respect to the Advisor  Class  shares of each Fund and such other
information as may be required by the 1940 Act and Rule 12b-1 thereunder.

SECTION 7. TERMINATION

This Plan may be  terminated  without  penalty  at any time with  respect to the
Advisor Class shares of any Fund by the vote of a majority of the Board,  by the
vote of a majority of the Independent  Members,  or by the vote of a majority of
the  outstanding  shares of the Advisor Class of that Fund.  Termination  of the
Plan with  respect to the Advisor  Class  shares of one Fund will not affect the
continued effectiveness of this Plan with respect to the Advisor Class shares of
any other Fund.

SECTION 8. AMENDMENTS TO THIS PLAN

This Plan may not be amended to increase materially the amount of compensation a
Fund is  authorized  to pay under  SECTION 1 hereof  unless  such  amendment  is
approved in the manner  provided for in SECTION 4 hereof,  and such amendment is
further  approved by a majority of the outstanding  shares of the Fund's Advisor
Class, and no other material  amendment to the Plan will be made unless approved
in the manner provided for approval and annual renewal in SECTION 4 hereof.

SECTION 9. RECORDKEEPING

The Issuer will preserve copies of this Plan (including any amendments  thereto)
and any related agreements and all reports made pursuant to SECTION 5 hereof for
a period of not less than six years  from the date of this  Plan,  the first two
years in an easily accessible place.

IN WITNESS WHEREOF, the Issuer has executed this Plan as of January 1, 2008.

     Issuer  identified  on SCHEDULE A (the  "Funds")  shall pay the  investment

     Funds,  a fee equal to 75 basis  points  (0.75%)  per annum of the  average

     "Distribution Fee").

b.   INDIVIDUAL  SHAREHOLDER  SERVICES  FEE.  For  purposes of paying  costs and

     the  first  sale of a B Class  share  from  which  such B Class  share  was
     derived.  Each  Fund's  obligation  to pay the  Distribution  Fee  shall be
     absolute  and  unconditional  and shall not be subject to dispute,  offset,
     counterclaim or any defense whatsoever,  at law or equity.  Notwithstanding
     the  foregoing,  the Issuers may modify or terminate  payments under this B
     Class Plan as provided in SECTION 8(C) below.

SECTION 3. INDIVIDUAL SHAREHOLDER SERVICES

Advisor may engage third parties to provide individual  shareholder  services to
the shareholders of the B Class shares ("Individual Shareholder Services").  The
payments  authorized by this Plan are intended to reimburse Advisor for expenses
incurred by it as a result of these  arrangements.  Such Individual  Shareholder
Services and related expenses relate to activities for which service fees may


                                       2


be  paid  as  contemplated  by  the  Conduct  Rules  of the  Financial  Industry
Regulatory  Authority  ("FINRA"),  and may include,  but are not limited to, (A)
individualized  and  customized  investment  advisory  services,  including  the
consideration  of shareholder  profiles and specific goals;  (B) the creation of
investment  models and asset  allocation  models for use by the  shareholder  in
selecting  appropriate Funds; (C) proprietary  research about investment choices
and the market in general;  (D) periodic  rebalancing of shareholder accounts to
ensure  compliance  with the selected asset  allocation;  (E)  consolidation  of
shareholder accounts in one place; and (F) other individual  services;  provided
that  if  FINRA  determines  that  any  of  the  foregoing  activities  are  not
permissible, any payment for such activities will automatically cease.

SECTION 4. TRANSFER OF RIGHTS

a.   Distributor may, from time to time, assign, transfer or pledge ("Transfer")
     to one or more  designees  (each an  "Assignee"),  its  rights  to all or a
     designated  portion of the Distribution Fee (but not  Distributor's  duties
     and obligations pursuant hereto), free and clear of any offsets,  claims or
     defenses  the  Issuer  may  have  against  Distributor  including,  without
     limitation, any of the foregoing based upon the insolvency or bankruptcy of
     Distributor.  Each such  Assignee's  ownership  interest in a Transfer of a
     designated portion of the Distribution Fee is hereinafter referred to as an
     "Assignee's  Portion." A Transfer pursuant to this Section shall not reduce
     or extinguish any claim of a Fund against Distributor.

b.   Distributor  shall  promptly  notify the Issuer in writing of each Transfer
     pursuant to this Section by providing the Issuers with the name and address
     of each such Assignee.

c.   Distributor  may direct  the Issuer to pay  directly  to an  Assignee  such
     Assignee's  Portion.  In such event,  Distributor  shall provide the Issuer
     with a  monthly  calculation  of (i) the  Distribution  Fee,  and (ii) each
     Assignee's Portion, if any, for such month (the "Monthly Calculation"). The
     Monthly Calculation shall be provided to each Fund by Distributor  promptly
     after the close of each month or such other time as agreed to by a Fund and
     Distributor  which allows timely payment of the Distribution Fee and/or the
     Assignee's  Portion.  No Fund  shall be  liable  for any  interest  on such
     payments  occasioned  by delayed  delivery  of the Monthly  Calculation  by
     Distributor.  In such event,  following  receipt  from  Distributor  of the
     notice of Transfer and each Monthly Calculation,  the Issuer shall make all
     payments  directly to the  Assignee or  Assignees  in  accordance  with the
     information  provided in such notice and Monthly  Calculation,  on the same
     terms and  conditions  as if such  payments were to be paid directly to the
     Advisor. Each Issuer shall be entitled to rely on Distributor's notices and
     Monthly  Calculations  in respect of  amounts to be paid  pursuant  to this
     Section.

d.   Alternatively,  in connection  with a Transfer,  Distributor may direct the
     Issuer to pay all of the Distribution Fee from time to time to a depository
     or  collection  agent  designated  by any  Assignee,  which  depository  or
     collection  agent may be delegated the duty of dividing  such  Distribution
     Fee between the  Assignee's  Portion  and the balance  (the  "Distributor's
     Portion"),  in which case only the Distributor's  Portion may be subject to
     offsets or claims a Fund may have against Distributor.


                                       3


SECTION 5. EFFECTIVENESS

This Plan has been approved by the vote of both (a) the Board and (b) a majority
of those  members  who are not  "interested  persons" as defined in the 1940 Act
(the "Independent Members"), and initially became effective September 3, 2002.

SECTION 6. TERM

This Plan will  continue  in full force and effect for a period of one year from
the date hereof, and successive  periods of up to one year thereafter,  provided
that each such  continuance is approved by a majority of (a) the Board,  and (b)
the Independent Members.


SECTION 7. REPORTING REQUIREMENTS

The Advisor shall administer this Plan in accordance with Rule 12b-1 of the 1940
Act.  The Advisor  shall  provide to the  Issuer's  Board,  and the  Independent
Members will review and approve in exercise of their fiduciary  duties, at least
quarterly,  a written  report of the  amounts  expended  under  this Plan by the
Advisor  with  respect  to the B  Class  shares  of each  Fund  and  such  other
information as may be required by the 1940 Act and Rule 12b-1 thereunder.

SECTION 8. TERMINATION AND SEVERABILITY

a.   This Plan may be terminated without penalty at any time with respect to the
     B Class  shares of any Fund by the vote of a majority of the Board,  by the
     vote of a majority of the Independent Members, or by the vote of a majority
     of the outstanding  shares of the B Class of that Fund.  Termination of the
     Plan with  respect  to the B Class  shares of one Fund will not  affect the
     continued  effectiveness of this Plan with respect to the B Class shares of
     any other Fund.

b.   If any provision of this Plan should be declared or made  invalid,  illegal
     or  unenforceable  in any  respect by a court  decision,  statute,  rule or
     otherwise,  the  validity,  legality and  enforceability  of the  remaining
     provisions shall not in any way be affected or impaired thereby.

c.   Notwithstanding  anything  to the  contrary  set  forth in this  Plan,  the
     Distribution  Fee  shall  not  be  terminated  or  modified   (including  a
     modification  by change in the rules  relating to the conversion of B Class
     shares of a Fund into A Class shares of the same Fund) and shall be paid to
     Distributor or as directed by Distributor  pursuant to SECTION 4 regardless
     of  Distributor's  termination as a Fund's  distributor,  with respect to B
     Class  shares  either (i) issued  prior to the date of any  termination  or
     modification;  (ii)  attributable to B Class shares issued through one or a
     series of exchanges  of B Class shares of another Fund that were  initially
     issued  prior to the date of such  termination  or  modification;  or (iii)
     issued as a dividend or distribution  upon B Class shares  initially issued
     or  attributable  to B Class  shares  issued  prior to the date of any such
     termination or modification except:


                                       4


          (A) to the extent  required by a change in the 1940 Act,  the rules or
     regulations  under the 1940 Act, the FINRA  Conduct  Rules or an order of a
     any court or governmental agency;

          (B) in connection  with a Complete  Termination  (as defined below) of
     this Plan; or

          (C) on a basis,  determined by the Board,  including a majority of the
     Independent  Members,  acting in good faith,  so long as from and after the
     effective date of such  modification or  termination:  (i) neither any Fund
     nor the Advisor pays,  directly or  indirectly,  a  Distribution  Fee or an
     Individual Shareholder Services Fee or to any person who is the holder of B
     Class shares of any Fund (but the foregoing shall not prevent  payments for
     transfer  agency or  subaccounting  services),  and (ii) the termination or
     modification of the  Distribution  Fee applies with equal effect to B Class
     issued either prior to or after such termination or modification.

d.   For purposes of this Plan, a "Complete Termination" shall have occurred if:
     (i) this Plan (and any successor  plan) is terminated with respect to all B
     Class shares of the Fund then outstanding or subsequently  issued; (ii) the
     payment by the Funds of the  Distribution  Fee with  respect to all B Class
     shares of each Fund is terminated;  and (iii) the Issuer does not establish
     concurrently  with or subsequent to such  termination  of this Plan another
     class of shares  which has  substantially  similar  characteristics  to the
     current B Class  shares,  including  the  manner of  payment  and amount of
     contingent deferred sales charge paid directly or indirectly by the holders
     of such shares.

SECTION 9. AMENDMENTS TO THIS PLAN

This Plan may not be amended to increase materially the amount of compensation a
Fund is  authorized  to pay under  SECTION 1 hereof  unless  such  amendment  is
approved in the manner  provided for in SECTION 6 hereof,  and such amendment is
further approved by a majority of the outstanding  shares of the Fund's B Class,
and no other material  amendment to the Plan will be made unless approved in the
manner provided for approval and annual renewal in SECTION 6 hereof.

SECTION 10. RECORDKEEPING

The Issuer will preserve copies of this Plan (including any amendments  thereto)
and any related agreements and all reports made pursuant to SECTION 7 hereof for
a period of not less than six years  from the date of this  Plan,  the first two
years in an easily accessible place.

SECTION 11. INDEPENDENT MEMBERS OF THE BOARD

So long as the Plan remains in effect,  the selection and  nomination of persons
to  serve  as  Independent  Members  on the  Board  shall  be  committed  to the
discretion   of  the   Independent   Members   on  the  Board  then  in  office.
Notwithstanding  the above,  nothing herein shall prevent the


                                       5


participation  of other persons in the selection and nomination  process so long
as a final decision on any such selection or nomination is within the discretion
of, and approved by, the Independent Members so responsible.

          IN WITNESS WHEREOF,  the Issuer has adopted this Plan as of January 1,
     2008.

                                     R CLASS

SECTION 1. FEES

a.   FEE. For purposes of paying  costs and expenses  incurred in providing  the
     distribution  services and/or individual  shareholder services set forth in
     SECTIONS 2 AND 3 below,  the series of the Issuer  identified on SCHEDULE A
     (the "Funds")  shall pay the investment  adviser  engaged by the Funds (the
     "Advisor"),  as paying agent for the Funds,  a fee equal to 50 basis points
     (0.50%)  per annum of the  average  daily net  assets of the  shares of the
     Funds' R Class of shares (the "Fee").

b.   APPLICABILITY  TO NEW FUNDS. If the Issuer desires to add additional  funds
     to the Plan,  whether  currently-existing  or created in the future (a "New
     Fund"),  and the Issuer's Board of Directors (the "Board") has approved the
     Plan for such New Fund in the  manner  set forth in SECTION 5 of this Plan,
     as well as by the then-sole  shareholder  of the R Class shares of such New
     Fund  (if  required  by  the  Investment  Company  Act  of  1940  or  rules
     promulgated  under the Act),  this Plan may be amended to provide that such
     New Fund will become subject to this Plan and will pay the Fee set forth in
     SECTION  1(A)  above,  unless  the  Board  specifies  otherwise.  After the
     adoption of this Plan by the Board with respect to the R Class of shares of
     the New Fund,  the term "Funds" under this Plan shall  thereafter be deemed
     to include the New Fund.

c.   CALCULATION  AND  ASSESSMENT.  Fees under this Plan will be calculated  and
     accrued daily by each Fund and paid to the Advisor monthly or at such other
     intervals as the Issuer and Advisor may agree.

SECTION 2. DISTRIBUTION SERVICES

The Advisor shall use the fee set forth in SECTION 1(A) of this Plan, to pay for
services in connection  with any activities  undertaken or expenses  incurred by
the  distributor  of the Funds'  shares (the  "Distributor")  or its  affiliates
primarily  intended to result in the sale of R Class shares of the Funds,  which
services may include,  but are not limited to, (A) payment of sales commissions,
ongoing   commissions  and  other  payments  to  brokers,   dealers,   financial
institutions  or others who sell R Class shares of the Funds pursuant to Selling
Agreements; (B) compensation to registered representatives or other employees of
Distributor who engage in or support  distribution of the Funds' R Class shares;
(C) compensation to, and expenses  (including  overhead and telephone  expenses)
of,  Distributor;  (D)  printing  of  prospectuses,   statements  of  additional
information and reports for other than existing  shareholders;  (E) preparation,
printing



and distribution of sales literature and advertising  materials  provided to the
Funds'  shareholders and prospective  shareholders;  (F) receiving and answering
correspondence   from   prospective    shareholders,    including   distributing
prospectuses, statements of additional information, and shareholder reports; (G)
provision of facilities to answer  questions from  prospective  investors  about
Fund shares;  (H) complying with federal and state securities laws pertaining to
the sale of Fund shares; (I) assisting investors in completing application forms
and  selecting  dividend  and other  account  options;  (J)  provision  of other
reasonable  assistance in connection with the  distribution of Fund shares;  (K)
organizing  and  conducting  of  sales  seminars  and  payments  in the  form of
transactional   compensation  or  promotional  incentives;  (L)  profit  on  the
foregoing; and (M) such other distribution and services activities as the Issuer
determines may be paid for by the Issuer  pursuant to the terms of this Plan and
in accordance  with Rule 12b-1 of the 1940 Act;  provided that if the Securities
and Exchange  Commission  determines that any of the foregoing  services are not
permissible   under  Rule  12b-1,   any  payments  for  such   activities   will
automatically cease.

SECTION 3. INDIVIDUAL SHAREHOLDER SERVICES

Advisor may engage third parties to provide individual  shareholder  services to
the shareholders of the R Class shares ("Individual Shareholder Services").  The
amount  set  forth  in  SECTION  1(A) of this  Plan may be paid to  Advisor  for
expenses  incurred  by it as a result  of these  arrangements.  Such  Individual
Shareholder Services and related expenses relate to activities for which service
fees may be paid as contemplated by the Conduct Rules of the Financial  Industry
Regulatory  Authority  ("FINRA"),  and may include,  but are not limited to, (A)
individualized  and  customized  investment  advisory  services,  including  the
consideration  of shareholder  profiles and specific goals;  (B) the creation of
investment  models and asset  allocation  models for use by the  shareholder  in
selecting  appropriate Funds; (C) proprietary  research about investment choices
and the market in general;  (D) periodic  rebalancing of shareholder accounts to
ensure  compliance  with the selected asset  allocation;  (E)  consolidation  of
shareholder accounts in one place; and (F) other individual  services;  provided

This  Plan  has been  approved  by the  vote of both  (a) the  Board,  and (b) a
majority  of those  members who are not  "interested  persons" as defined in the
1940 Act (the "Independent Members"),  and initially became effective August 29,
2003.

SECTION 5. TERM

This Plan will  continue  in full force and effect for a period of one year from

SECTION 6. REPORTING REQUIREMENTS

respect to the R Class shares of each Fund and such other  information as may be
required by the 1940 Act and Rule 12b-1 thereunder.

SECTION 7. TERMINATION

This Plan may be  terminated  without  penalty at any time with respect to the R
Class  shares of any Fund by vote of a majority  of the Board,  by the vote of a
majority  of the  Independent  Members,  or by the  vote  of a  majority  of the
outstanding  shares of the R Class of that  Fund.  Termination  of the Plan with
respect  to the R Class  shares  of one  Fund  will  not  affect  the  continued
effectiveness of this Plan with respect to the R Class shares of any other Fund.

SECTION 8. AMENDMENTS TO THIS PLAN

This Plan may not be amended to increase materially the amount of compensation a
Fund is  authorized  to pay under  SECTION 1 hereof  unless  such  amendment  is
approved in the manner  provided for initial  approval in SECTION 6 hereof,  and
such amendment is further  approved by a majority of the  outstanding  shares of

SECTION 5 hereof.

and any related agreements and all reports made pursuant to SECTION 6 hereof for

so responsible.

As required by Rule 18f-3 under the 1940 Act,  this Plan  describes the multiple
class system for certain series of shares of the Issuer,  including the separate
class arrangements for shareholder  services and/or  distribution of shares, the

                                       1


SECTION 2.        FEATURES OF THE CLASSES

a.   DIVISION INTO CLASSES.  Each series of shares of the Issuers  identified in
     SCHEDULE  A  attached  hereto,  and each  series of  shares  of any  Issuer
     subsequently added to this Plan (collectively,  the "Funds"), may offer one
     or more of the following classes of shares:  Investor Class,  Institutional
     Class,  Advisor Class,  A Class, B Class, C Class and R Class.  The classes
     that each Fund is authorized  to issue  pursuant to this Plan are set forth
     in SCHEDULE A. Shares of each class of a Fund shall  represent an equal pro
     rata interest in such Fund,  and generally,  shall have  identical  voting,
     dividend, liquidation and other rights, preferences,  powers, restrictions,
     limitations,  qualifications,  and terms and  conditions,  except that each
     class of shares shall: (A) have a different designation; (B) bear any Class
     Expenses,  as defined in SECTION  3D(3) below;  (C) have  exclusive  voting
     rights on any matter  submitted to shareholders  that relates solely to its
     service  arrangement;  and (D) have  separate  voting  rights on any matter
     submitted to  shareholders  in which the interests of one class differ from
     the interests of any other class.

b.   MANAGEMENT FEES.

     agreement  (the  "Management   Agreement")  with  either  American  Century

     Management,  Inc., each a registered  investment  adviser (each referred to

     institutional  shareholders,  such as  corporations  and retirement  plans,
     other  pooled  accounts,  and  individual  shareholders  that meet  certain
     investment  minimums  established  from time to time by the Advisor.  These
     minimums  may  be  waived  or  lowered  in  certain  situations  as  deemed
     appropriate by the Advisor. Institutional Class shares are not eligible for
     purchase by insurance  companies,  except in connection  with a product for
     defined benefit plans not involving a group annuity contract.

     (3) ADVISOR  CLASS UNIFIED FEE. For each Fund listed on SCHEDULE A as being

     current  Investor Class  prospectus or prospectus  supplement.  The Advisor
     Class  is  intended  to be  sold  to  employer-sponsored  retirement  plans
     (including    participant    directed    plans),    insurance    companies,
     broker-dealers, banks and other financial intermediaries.

     current Investor Class prospectus or prospectus supplement.  The R Class is

SECTION 3. ALLOCATION OF INCOME AND EXPENSES

a.   DAILY DIVIDEND FUNDS.  Funds that declare  distributions  of net investment
     income  daily to maintain  the same net asset value per share in each class
     ("Daily  Dividend  Funds") will allocate  gross income and expenses  (other
     than  Class  Expenses,  as  defined  below)  to each  class on the basis of
     "relative net assets  (settled  shares)".  Realized and unrealized  capital
     gains and losses will be  allocated  to each class on the basis of relative
     net assets.  "Relative net assets (settled shares)," for this purpose,  are
     net  assets  valued  in  accordance  with  generally  accepted   accounting
     principles but excluding the value of subscriptions receivable, in relation
     to the net assets of the particular Daily Dividend Fund.  Expenses to be so
     allocated include Issuer Expenses and Fund Expenses, each as defined below.

b.   NON-DAILY DIVIDEND FUNDS. The gross income, realized and unrealized capital
     gains and losses and  expenses  (other than Class  Expenses)  of each Fund,
     other than the Daily  Dividend  Funds,  shall be allocated to each class on
     the basis of its net asset  value  relative  to the net asset  value of the
     Fund.  Expenses to be so allocated  also include  Issuer  Expenses and Fund
     Expenses.


                                       5


c.   APPORTIONMENT OF CERTAIN EXPENSES.  Expenses of a Fund shall be apportioned
     to each class of shares depending on the nature of the expense item. Issuer
     Expenses and Fund  Expenses  will be allocated  among the classes of shares
     pro rata based on their  relative  net asset  values in relation to the net
     asset value of all outstanding shares in the Fund.  Approved Class Expenses
     shall be allocated to the particular class to which they are  attributable.
     In addition,  certain expenses may be allocated differently if their method
     of imposition changes. Thus, if a Class Expense can no longer be attributed
     to a class, it shall be charged to a Fund for allocation among classes,  as
     determined by the Advisor.

d.   DEFINITIONS.

     (1) ISSUER EXPENSES.  "Issuer Expenses" include expenses of the Issuer that
     are not  attributable  to a  particular  Fund or  class  of a Fund.  Issuer
     Expenses  include  fees  and  expenses  of  those  Independent   Directors,
     including  counsel  fees  for  the  Independent   Directors,   and  certain
     extraordinary  expenses  of the  Issuer  that  are  not  attributable  to a
     particular Fund or class of a Fund.

     (2) FUND EXPENSES.  "Fund Expenses" include expenses of the Issuer that are
     attributable to a particular fund but are not  attributable to a particular
     class of the Fund. Fund Expenses include (i) interest expenses, (ii) taxes,
     (iii) brokerage expenses, and (iv) certain extraordinary expenses of a Fund
     that are not attributable to a particular class of a Fund.

     (3) CLASS EXPENSES.  "Class Expenses" are expenses that are attributable to
     a  particular  class of a Fund and  shall be  limited  to:  (i)  applicable
     unified  fee;  (ii)  payments  made  pursuant  to the  12b-1  Plan  of each
     applicable Class; and (iii) certain extraordinary  expenses of an Issuer or
     Fund that are attributable to a particular class of a Fund.

     (4) EXTRAORDINARY EXPENSES.  "Extraordinary expenses" shall be allocated as
     an Issuer  Expense,  a Fund  Expense or a Class  Expense in such manner and
     utilizing such methodology as the Advisor shall reasonably determine, which
     determination shall be subject to ratification or approval of the Board and
     shall be consistent with applicable legal principles and requirements under
     the 1940 Act and the Internal  Revenue Code, as amended.  The Advisor shall
     report to the Board quarterly regarding those  extraordinary  expenses that
     have  been  allocated  as Class  Expenses.  Any such  allocations  shall be
     reviewed by, and subject to the approval of, the Board.

SECTION 4. EXCHANGE PRIVILEGES

Subject to the restrictions and conditions set forth in the Funds' prospectuses,
shareholders  may (i)  exchange  shares of one class of a Fund for shares of the
same class of another Fund,  (ii) exchange  Investor  Class shares for shares of
any fund within the American  Century  family of funds that only offers a single
class of shares (a "Single Class Fund"), and (iii) exchange shares of any Single
Class Fund for Investor  Class shares of another Fund,  provided that the amount
to be exchanged meets the applicable  minimum  investment  requirements  and the
shares  to  be  acquired  in  the  exchange  are   qualified  for  sale  in  the
stockholder's state of residence.


                                       6


SECTION 5. CONVERSION FEATURES

Conversions  from one class of a Fund's  shares into another class of shares are
not permitted; PROVIDED, HOWEVER, that if a shareholder of a particular class is
no longer  eligible  to own  shares of that  class,  upon  prior  notice to such
shareholder,  those  shares will be  converted to shares of the same Fund but of
another class in which such shareholder is eligible to invest.  Similarly,  if a
shareholder becomes eligible to invest in shares of another class that has lower
expenses than the class in which such shareholder is invested,  such shareholder
may be  eligible  to convert  into shares of the same Fund but of the class with
the lower expenses.

SECTION 6. QUARTERLY AND ANNUAL REPORTS

The Board shall receive  quarterly and annual  reports  concerning all allocated
Class  Expenses and  distribution  and  servicing  expenditures  complying  with
paragraph  (b)(3)(ii) of Rule 12b-1,  as it may be amended from time to time. In
the reports, only expenditures properly attributable to the sale or servicing of
a  particular  class of  shares  will be used to  justify  any  distribution  or
servicing fee or other expenses charged to that class.  Expenditures not related
to the sale or  servicing  of a  particular  class shall not be presented to the
Board to justify any fee attributable to that class. The reports,  including the
allocations  upon  which  they are  based,  shall be  subject  to the review and
approval  of the  Independent  Directors  of the  Issuer  who have no  direct or
indirect  financial  interest in the  operation  of this Plan in the exercise of
their fiduciary duties.

SECTION 7. WAIVER OR REIMBURSEMENT OF EXPENSES

Expenses  may be waived or  reimbursed  by any  adviser  to the  Issuer,  by the
Issuer's  underwriter or by any other provider of services to the Issuer without
the prior  approval of the Board,  provided that the fee is waived or reimbursed
to all shares of a particular Fund in proportion to their relative average daily
net asset values.

SECTION 8. EFFECTIVENESS OF PLAN

Upon  receipt of  approval  by votes of a majority of both (a) the Board and (b)
the Independent Directors, this Plan shall become effective September 4, 2007.

SECTION 9. MATERIAL MODIFICATIONS

This  Plan may not be  amended  to  modify  materially  its  terms  unless  such
amendment  is approved a majority of both (a) the Board and (b) the  Independent
Directors;  PROVIDED;  HOWEVER;  that a new Fund may be added by the Issuer upon
approval by that Issuer's Board by executing a new Schedule A to this Plan.


                                       7

             STATEMENT OF POLICY ON PERSONAL SECURITIES TRANSACTIONS

                                   ADOPTED BY

                      NORTHWESTERN MUTUAL SERIES FUND, INC.
                           MASON STREET ADVISORS, LLC
                              (AS OF JULY 2, 2007)

I.   INTRHODUCTION

     Investment  companies,  investment advisers and their officers,  directors,
employees and affiliated  persons face inherent  conflicts of interest when they
trade in  securities  for their own  accounts.  They have access to  information
about their client's securities  transactions,  which they can exploit for their
own benefit.

     Rule 204A-1 under the Investment Advisers Act (the "Advisers Act") and Rule
17j-1  under  the   Investment   Company  Act  (the  "1940  Act")  require  each
SEC-registered  investment adviser and each SEC-registered investment company to
adopt  written codes of ethics  containing  provisions  reasonably  necessary to
prevent employees and certain other persons from engaging in personal trading in
violation of these Rules, and to maintain records, use reasonable diligence, and
adopt and implement  procedures as reasonably  necessary to prevent,  detect and
correct violations. It is unlawful to engage in personal securities transactions
in violation of these Rules, general antifraud rules under the federal and state
securities laws and fiduciary duties owed to clients.

     This STATEMENT OF POLICY ON PERSONAL SECURITIES TRANSACTIONS ("Statement"),
which is designed to ensure that personal securities transactions do not violate
applicable law and fiduciary duties, has been adopted by (i) Northwestern Mutual
Series Fund, Inc. (SF), as an SEC-registered investment company (the "Fund") and
(ii) Mason Street Advisors,  LLC (MSA) as an SEC-registered  investment  adviser
and as investment adviser to the Fund (all collectively the "Companies").

     This  Statement  applies to Access Persons as defined under Rule 204A-1 and
Rule 17j-1 (see Definitions below).  Access Persons are responsible for reading,
understanding and observing the Statement, keeping in mind that the interests of
the Fund and other MSA Clients must be placed first even in a circumstance  that
is not  covered by a specific  provision.  Access  Persons are  responsible  for
reporting  violations of the Statement to Michael  Zielinski,  Chief  Compliance
Officer  for  the   Companies   (the  "CCO").   All  reports  shall  be  treated
confidentially  to the extent  permitted by  applicable  law,  and  investigated
promptly and appropriately.  Alternatively, reports may be submitted THROUGH the
Ethics  Resource  Center  of The  Northwestern  Mutual  Life  Insurance  Company
("Northwestern  Mutual") to help ensure  anonymity.  Any retaliation  against an
individual  who reports a violation  is  prohibited  and  constitutes  a further
violation of the Statement.




     Questions concerning the Statement and requests for further information and
related  forms and  procedures  should be directed to Michael  Zielinski (or his
designee).

               participates in, or obtains information  regarpurchase or sale of
               Reportable Securities by the Fund; OR

          (ii) whose functions relate to the making of any recommendations  with
               respect to such purchases or sales.

     1.   Each director of MSA;

     2.   Each officer of MSA;

     3.   Each employee of MSA; and

     4.   The following other individuals:(1)

          (i)  Each person who provides  investment  advice on behalf of MSA and

          (ii) Each person  occupying  a similar  status or  performing  similar
               functions to an officer or director of MSA.

"ACCESS  PERSON" may also include any other  persons who the CCO  determines  to
treat as Access Persons  because of their status,  the functions they perform or
the information they obtain.

"AUTOMATIC  INVESTMENT PLAN" means a program in which regular periodic purchases
(or  withdrawals) are made  automatically  in (or from)  investment  accounts in
accordance with a predetermined schedule and allocation. An automatic investment
plan includes a dividend reinvestment plan, stock purchase plan,  investments by

     directors or employees of MSA.


                                       2


re-balancings,  exchanges,  purchases  and  withdrawals,  but does  NOT  include
transactions that override any such program or non-systematic transactions.

"BENEFICIAL  OWNERSHIP"  shall have the same  meaning as under Rule  16a-1(a)(2)
under the  Securities  Exchange Act of 1934 in  determining  whether a person is
subject  to  the  provisions  of  Section  16  of  that  Act,  except  that  the
determination  of direct or  indirect  Beneficial  Ownership  shall apply to ALL
Reportable Securities which an Access Person has or acquires.

A person has Beneficial Ownership if he or she, directly or indirectly,  through
any contract,  arrangement,  understanding, or relationship has or shares in the
opportunity,  directly or  indirectly,  to profit or share in any profit derived
from a transaction or security. Examples include:

     o    Securities held by members of an Access Person's Immediate Family

securities  held by a  corporation  or  similar  entity  in which he or she owns
securities if he or she is not a controlling  shareholder AND he or she does not
have or share in investment control over the portfolio. For example,  Beneficial
Ownership  would not exist with respect to an  individual  who is a trustee of a
trust,  but  neither  has  investment  discretion  nor  is a  grantor  or  trust
beneficiary.

An Access  Person shall not be deemed to  beneficially  own  securities  held by
his/her  minor  children  unless  the  Access  Person  or a member of his or her
Immediate Family has the ability to influence, direct or control the investments
of his/her minor children.

with the  Advisers  Act but, in general,  means any person for whom MSA provides
investment advisory services for compensation.

"CONTROL"  shall have the same  meaning as that set forth in section  2(a)(9) of
the 1940 Act.

"EXCHANGE TRADED FUNDS ("ETFS")" shall mean a registered investment company that
operates pursuant to an order from the SEC exempting it from certain  provisions
of the Investment Company Act so that the ETF may issue securities that trade in

companies and those organized as unit investment trusts.

"HIGH QUALITY  SHORT-TERM DEBT  INSTRUMENT"  shall mean any instrument  having a
maturity  at  issuance  of less  than 366 days and  which is rated in one of the
highest two rating  categories  by a Nationally  Recognized  Statistical  Rating
Organization, or which is unrated but is of comparable quality.


                                       3


"IMMEDIATE  FAMILY"  generally means any relative by blood or marriage living in
the individual's  household,  any domestic partner or other minor child residing
in his  or  her  household  and,  whether  or  not  living  in the  individual's
household,  any other relative with respect to whose  investments the individual
has influence or control.

"INDEPENDENT  MSA  DIRECTOR"  means  MSA  directors  that  are not  officers  or
employees of MSA or officers, directors or employees of any affiliated person of
MSA.

"INDEPENDENT FUND DIRECTOR" means a member of the Board of Directors of the Fund
who is not an  "interested  person" as defined in Section  2(a)(19)  of the 1940
Act.

"INITIAL PUBLIC  OFFERING" means a registered  offering under the Securities Act
of 1933, where the issuer, immediately before the registration,  was not subject
to the reporting  requirements of the Securities Exchange Act of 1934. This term
does not include secondary public offerings.

"INVESTMENT PERSON" means an Access Person who makes, or participates in making,
decisions  regarding  the purchase or sale of  securities by or on behalf of any
Client and any person who directly  assists in the process.  Investment  Persons
include portfolio managers,  assistant  portfolio  managers,  research analysts,
traders, and other individuals designated by the CCO.

"LIMITED  OFFERING"  means an offering exempt from  registration  under specific
private offering and investor exemptions provided in the Securities Act of 1933.
Such investments are commonly referred to as private placements.

"REPORTABLE  FUND" means any  registered  investment  company under the 1940 Act
(other than a money market fund) for which MSA serves as  investment  adviser or
sub-adviser or whose investment adviser or principal  underwriter  Controls MSA,
is Controlled  by MSA or is under common  Control with MSA. See Appendix A for a
list of such companies.

"REPORTABLE  SECURITIES"  means  the same as the term used in Rule  204A-1,  and
includes any common stock,  preferred  stock,  closed end-  investment  company,
Reportable  Fund,  debt  securities,  futures  contracts  and options on futures
contracts  relating  to any  stock,  bond or  index,  and any  other  investment
contract or other  instrument  that is  considered  a "security"  under  Section
202(a)(18)  of the Advisers  Act.  "Reportable  Securities"  also include  ETFs.

     o    Shares  issued by  open-end  funds  OTHER  THAN  Reportable  Funds and
          ETFs(2); and

-------------------------------
(2)  Transactions  and holdings in shares of  closed-end  investment  companies,
     ETFs and offshore funds are reportable regardless of affiliation.



                                       4


    o    Shares  issued by unit  investment  trusts  (other than ETFs) that are
          invested  exclusively in one or more open-end funds, none of which are
          Reportable Funds.


III. PROHIBITED AND LIMITED TRANSACTIONS

     A.   INITIAL PUBLIC OFFERINGS

     Investment  Persons are not permitted to acquire,  directly or  indirectly,
     securities in an Initial Public Offering.  Securities in such offerings may
     be purchased or received, however, when an individual has an existing right
     to do so based on his or her status as an  investor or  similarly  situated
     party or the security is acquired in connection  with a  reorganization  or
     otherwise  involves no investment  discretion on the part of the recipient,
     except in connection  with the exercise of voting or similar  rights.  Such
     situations must be brought to the attention of the CCO when applicable.

     All other Access Persons (except  Independent  Fund Directors) are required
     to obtain  approval  from the CCO  before  they  acquire  securities  in an
     Initial  Public  Offering.  Approval  shall be  obtained by  following  the
     Pre-Clearance  Procedures  set forth  elsewhere  in this  Statement,  or as
     otherwise directed by the CCO.

     B.   LIMITED OFFERINGS

     Access Persons (except  Independent  Fund Directors) are required to obtain
     approval  from the CCO or his  designee  before they  acquire,  directly or
     indirectly, securities in a Limited Offering. Approval shall be obtained by
     following  the  Pre-Clearance   Procedures  set  forth  elsewhere  in  this
     Statement, or as otherwise directed by the CCO.

     C.   EXCESSIVE TRADING OF MUTUAL FUND SHARES

     Access Persons are expected to abide by trading  restrictions  imposed by a
     mutual fund that are  described  in its  prospectus.  Additionally,  Access
     Persons (except  Independent Fund Directors) are required to hold shares of
     a Reportable Fund (which is defined to exclude money market funds) that are
     purchased for the lesser of a calendar  month or thirty (30) calendar days,
     including the date of purchase and date of sale.  This holding  period does
     not apply to  transactions  effected  pursuant to an  Automatic  Investment
     Plan, but does apply to all  NON-SYSTEMATIC  transactions  such as periodic
     re-balancing.

     ---------------------------------------------------------------------------

     NOTE: THE FOLLOWING  PROVISIONS D THROUGH F DESCRIBE PROHIBITED  INVESTMENT
     ACTIVITIES,  BUT THEY DO NOT APPLY TO PERSONAL  SECURITIES  TRANSACTIONS OF
     ACCESS  PERSONS THAT ARE EFFECTED  PURSUANT TO  AUTOMATIC  INVESTMENT  PLAN
     (WITH THE EXCEPTION OF THE INITIAL  AUTOMATIC  INVESTMENT PLAN  TRANSACTION
     AND TRANSACTIONS  THAT OVERRIDE ANY SUCH PROGRAM).  ADDITIONALLY,  PERSONAL
     SECURITIES  TRANSACTIONS  OF ACCESS PERSONS ARE NOT IMPLICATED  UNDER THESE
     PROVISIONS IF THE FUND OR OTHER CLIENT  TRANSACTION IN QUESTION IS EFFECTED
     IN RESPONSE TO  PROGRAMMED  TRADING  DESIGNED,  FOR  EXAMPLE,  TO ALIGN THE
     FUND'S OR OTHER CLIENT'S  INVESTMENT  PORTFOLIO  WITH THE  PERFORMANCE OF A
     MARKET  INDEX.  ACCESS  PERSONS  ARE  REMINDED,   HOWEVER,  THAT  OBTAINING
     PRE-CLEARANCE  FOR A TRANSACTION  AS REQUIRED UNDER THIS STATEMENT DOES NOT
     RELIEVE THEM FROM


                                       5


     CONDUCTING THEIR PERSONAL  SECURITIES  TRANSACTIONS IN FULL COMPLIANCE WITH
     THE PROVISIONS OF THIS STATEMENT AND APPLICABLE LAW,  INCLUDING  COMPLIANCE
     WITH THE PROHIBITIONS ON THE FOLLOWING INVESTMENT ACTIVITIES.

     ---------------------------------------------------------------------------

     D.   FRONT-RUNNING

     The  term  "front-run"   means  knowingly  trading  before  a  contemplated
     transaction by a Client,  whether or not the Access  Person's trade and the
     Client's trade take place in the same market in order to take advantage of,
     or avoid  changes in, market prices  effected by Client  transactions  in a
     Reportable Security. An Access Person is prohibited from front-running.

     E.   SCALPING

     An  Access  Person is  prohibited  from  purchasing  (or  selling  short) a
     Reportable  Security (or its  economic  equivalent)  with the  intention of
     recommending  that the security be purchased (or sold) for a Client for the
     purpose  of  supporting  or  increasing  (or  protecting)  the price of the
     security for the benefit of the Access  Person,  rather than the benefit of
     the Client. This activity,  referred to as "scalping" is prohibited whether
     or not an Access Person realizes a profit from the subject transaction.

     F.   BLACKOUT PERIODS

     An  Access  Person  is  prohibited  from  engaging  in a  transaction  in a
     Reportable  Security  which such  person  knows or should have known at the
     time there to be pending,  on behalf of any Client, a "buy" or "sell" order
     in that same  security.  The  existence of recent Client trades and pending
     orders will be checked as part of the  Pre-Clearance  Process  described in
     Section V. hereof, and pre-clearance may be denied if the CCO determines it
     is inconsistent with the best interests of any Client.

     G.   LIMIT ORDERS.

     Access  Persons that are subject to the  pre-clearance  provisions  of this
     Statement  generally should avoid placing "good until cancelled"  orders or
     any limit  orders  other than a  "same-day"  limit  order.  Such orders are
     difficult to pre-clear and can cause inadvertent pre-clearance violations.

     H.   INSIDER TRADING

     Access Persons are reminded that they are prohibited  from trading,  either
     personally  or for the accounts of the Fund or other  Clients,  on material
     non-public  information or communicating material non-public information to
     others in violation of the law. Access Persons are responsible for ensuring
     they are in compliance  with any insider  trading  policies and  procedures
     that may be applicable to them, including MSA's Policy Statement on Insider
     Trading and Northwestern Mutual's Guidelines for Business Conduct.


                                       6


     I.   HEDGE FUNDS, INVESTMENT CLUBS AND PARTNERSHIPS

     Access Persons  (except  Independent  Fund  Directors) are not permitted to
     participate in hedge funds, investment clubs, partnerships or other similar
     investment  vehicles  unless  approved in advance by the CCO (or his or her
     designee).  Any approval will be  conditioned  upon the person  providing a
     written  certification that he or she does not and will not have any direct
     or  indirect  influence  or  control  over  trading  for such  vehicle,  or
     alternatively,  subjecting  all the  underlying  securities  trading in the
     vehicle to the  Statement,  including  the  Statement's  pre-clearance  and
     reporting requirements.


IV.  REPORTING REQUIREMENTS


     A.   EXEMPTIONS

          1.   NON-INFLUENCE   AND   NON-CONTROL    ACCOUNTS.    The   reporting

               Securities  held in an account  over which an  individual  has no
               direct or indirect influence or control.  Individuals  wishing to
               exempt  accounts  over  which  they have no  direct  or  indirect
               influence or control must obtain  advance  approval from the CCO.
               Any approval will be  conditioned  upon  providing an initial and
               annual  written  certification  that he or she  does not have any
               direct or indirect influence or control over the account.

          2.   INDEPENDENT  FUND DIRECTORS.  Unless  otherwise  requested by the
               CCO, Independent Fund Directors are not required to file Holdings
               Reports or  Transaction  Reports unless he or she knew or, in the
               ordinary  course of fulfilling his or her official  duties as the
               Fund  director  should have known that  during the 15-day  period
               immediately  before  or after  the  director's  transaction  in a
               Reportable  Security,  the Fund  purchased or sold the Reportable
               Security,  or the  Fund  or  its  investment  adviser  considered
               purchasing or selling the Reportable Security.

     prior to the date the  individual  becomes an Access Person for the initial


                                       7

     in  the  Northwestern  Mutual  Series  Fund,  Inc.  that  are  effected  in
     connection with variable life and variable  annuity  transactions,  are not
     required  to be  reported  to the extent the Access  Person has  authorized
     Northwestern Mutual to release such holdings information to the CCO.(3)

     D.   TRANSACTION REPORTS

     1.  GENERAL.  Within 30 days after the end of each calendar  quarter,  each
     Access  Person  is  required  to  report  all  transactions  in  Reportable

     trade  confirmations and quarterly  statements  directly from those brokers
     identified to MSA by the Access person pursuant to paragraph 5 below within
     30  days  from  the end of  each  calendar  quarter.  If  MSA's  compliance
     department is unable to obtain duplicate  confirms and statements  directly
     from the brokers, or if such confirms and statements do not contain all the
     information required to be reported by the Access Person, the Access Person
     will be required  to provide  this  information  to MSA's CCO or his or her
     designee.

     reporting  obligations.(5)  However,  if  he  or  she  does  not  authorize

     an Access Person,  each Access Person (except  independent  Fund directors)
     must  report all  brokerage  accounts in which any  securities  are held or
     pursuant to which  transaction  may be effected  for the direct or indirect
     benefit  of  the  Access  Person.  In  addition,   Access  Persons  (except
     independent  Fund directors)  must report,  within 30 days after the end of
     each calendar quarter,  any new accounts  established during the quarter in

     report must  include the name of the broker,  dealer or bank,  the date the
     account was established, and the date the report is submitted by the Access

V.   ACCESS PERSON PRE-CLEARANCE REQUIREMENTS

Independent  Fund  Directors  are exempt  from all  pre-clearance  requirements.
Independent MSA Directors must pre-clear  transactions  in Limited  Offerings or
Initial  Public  Offerings;  however,  such  persons  are exempt  from all other
pre-clearance requirements. ALL OTHER ACCESS PERSONS MUST PRE-CLEAR TRANSACTIONS
IN ALL  REPORTABLE  SECURITIES,  except  for  those  exempt  from  pre-clearance
identified below.

     A.   PRE-CLEARANCE PROCESS
     Access  Persons are  required to  pre-clear a  transaction  by entering the
     transaction  into  the  Protegent  PTA  ("PTA")  system  available  on  the
     internet.  The  pre-clearance  request will identify  Limited  Offerings or
     Initial  Public  Offerings and such requests will be routed to MSA's CCO or
     his or her designee for his  approval.  Access  Persons will be notified by
     the PTA system when approval has been granted.

     B.   REPORTABLE SECURITIES AND TRANSACTIONS EXEMPT FROM PRE-CLEARANCE
     The following  Reportable  Securities and  Transactions are exempt from the
     pre-clearance requirements of this Section. (These transactions continue to
     be subject to the restrictions set forth in this Statement, including those
     enumerated in Section III.)

          1.   REPORTABLE FUNDS.  Transactions in Reportable Funds. A listing of
               such funds will be maintained on the Attached Appendix A.

          2.   REPORTABLE SECURITIES EXEMPTED FROM PRE-CLEARANCE BY THE CCO.

                    MARKET CAP OF $5 BILLION OR GREATER.  (THIS  EXEMPTION  WILL
                    NOT APPLY TO MSA'S  LARGE CAP TEAM,  MID-CAP  TEAM OR EQUITY
                    TRADING   DEPARTMENT.   SUCH   TRANSACTIONS   STILL  REQUIRE
                    PRE-CLEARANCE.)

               o    TRANSACTIONS  IN  MUNICIPAL   SECURITIES,   PROVIDING  THESE
                    SECURITIES ARE NO LONGER TRADED FOR MSA'S CLIENTS.


                                       9


               o    REPORTABLE SECURITIES WHOSE VALUE IS BASED UPON THE VALUE OR
                    CHANGES IN VALUE OF A BROAD-BASED  MARKET INDEX  (DEFINED AS
                    AN INDEX CONSISTING OF 100 OR MORE UNDERLYING SECURITIES) OR
                    WHOSE VALUE IS BASED UPON THE VALUE OF A COMMODITY.

               o    MSA'S CCO OR HIS OR HER DESIGNEE MAY GRANT AN EXEMPTION FROM
                    PRE-CLEARANCE FOR CERTAIN REPORTABLE SECURITIES IF HE OR SHE
                    DETERMINES THAT MSA CLIENT TRANSACTIONS WOULD BE UNLIKELY TO
                    HAVE  ANY  MATERIAL  IMPACT  ON  THE  MARKET  PRICE  OF  THE
                    REPORTABLE SECURITY.

          3.  NON-VOLITIONAL   TRANSACTIONS.   Reportable  Securities  that  are
          acquired or disposed of without the Access  Person's  discretion as to
          time or amount including, for example, (i) securities acquired through
          stock splits, reverse stock splits, mergers, consolidations, spin-offs
          and other similar corporate  reorganizations  generally  involving all
          holders of the same class of securities,  (ii) an involuntary  sale as
          the result of a company exercising a call provision on its outstanding
          debt,  and (iii)  assignments  of options or  exercises  of options at

          Acquisitions  of  securities  through  stock  dividends  and  dividend
          reinvestment  plans ("DRIPs") and stock acquired  through the exercise
          of rights that are issued pro rata to all holders of the same class of
          securities.

          5. EMPLOYER  STOCK OPTION PLANS.  Transactions  involving the exercise
          and/or  purchase of  securities  pursuant to an employer  stock option
          plan. Such plans may be applicable to persons subject to the Statement
          because the Access Person has  Beneficial  Ownership of their account.
          The sale of securities received from such plans must be pre-cleared.

          6. TENDER OFFERS FOR ALL SHARES.  Transactions pursuant to a bona fide
          tender  offer  made  for any and all  outstanding  securities  held by
          holders of the same class of  securities.  HOWEVER,  tender offers for
          less than all outstanding securities of a class must be pre-cleared.

          7. NON-INFLUENCE AND NON-CONTROL  ACCOUNTS.  Transactions  effected in
          Reportable  Securities held in an account over which an individual has
          no direct or indirect  influence  or control.  Individuals  wishing to
          exempt  accounts over which they have no direct or indirect  influence
          or control  must obtain  advance  approval  from the CCO. Any approval
          will be  conditioned  upon  providing  an initial  and annual  written
          certification  that he or she does not have  any  direct  or  indirect
          influence or control over the account.

          8.  Charitable  Donations of Reportable  Securities.  Transactions  in
          Reportable Securities that are gifted to charitable  organizations are
          exempt from all trading restrictions, subject to CCO approval.

                                       10


C.   PRE-CLEARANCE STANDARDS.

     1.  GENERAL.  Trades will only be  pre-cleared  if it is  determined  that,
     considering  all of the facts and  circumstances,  the  transaction  is not
     inconsistent with the provisions of this Statement.  Pre-clearance requests
     must be  submitted  on such form and in such manner as the CCO shall direct
     and shall be reviewed  against  recent and pending  executed  transactions,
     open orders and current investment recommendations for Clients.

     No  individual  authorized  to  pre-clear   transactions  may  pre-clear  a
     transaction  involving  a  Reportable  Security  in  which  he or  she  has
     Beneficial Ownership.

     2. COMPLIANCE WITH INSIDER TRADING POLICIES.  In connection with requesting
     pre-clearance  of a personal  securities  transaction,  Access  Persons are
     reminded  of  their   obligation  to  adhere  to  applicable   Company  and
     Northwestern  Mutual  policies  with  respect to  material  and  non-public
     information.

     3. DUTIES OF  INVESTMENT  PERSONS.  A security  shall be  considered  to be
     recommended  when a buy or sell  recommendation  is  made by an  Investment
     Person for a  Client's  account,  or such  recommendation  is under  active
     consideration by an Investment Person. An Investment Person may not fail to
     make a  recommendation  to a Client  in order  to avoid  limitations  on or
     conflicts with regard to his or her personal securities transactions.

     4. SEVEN-DAY  BLACKOUT PERIOD.  Clearance will not usually be given for any
     personal  transaction  in a  Reportable  Security  that is  proposed  to be
     effected  during the seven  calendar day period after either an  investment
     recommendation  is made for a  Client's  account  with  respect to the same
     security (or  securities  convertible  into the  security) or a buy or sell
     order for a Client's account is executed or while a Client order is pending
     for that security (or securities convertible into the security) ("Seven-Day
     Blackout  Period").  HOWEVER,  pre-clearance  may be granted to sell such a
     security  during the Seven-Day  Blackout  Period  provided the security has
     been disposed of first for all Clients  intending to sell such  securities.
     Additionally,  Client  trades  executed  within seven days after a personal
     transaction is effected will be subject to review, and the CCO reserves the
     right to take any action with respect to such personal transactions that he
     determines  appropriate  to  help  ensure  that  Client  interests  are not
     undermined  by  the  personal  investment  activities  of  Access  Persons,
     including the actions discussed in Section VI.F. of this Statement.

     The Seven-Day Blackout Period shall not apply:

          (i) If the Access Person's  transactions  amount to 500 shares OR LESS
          (or  equivalent  derivatives)  in the common stock of a company with a
          market  capitalization  of $5  billion  OR  MORE  at the  time  of the
          transaction.   These  diminimus   transactions   are  subject  to  the
          limitations  in Section  III above


                                       11


          (including  the  black-out  period  specified  there),  are subject to
          reporting in accordance with Section IV above,  and may be exempt from
          pre-clearance  for many Access Persons as provided in Section  V(b)(2)
          above.  IN ADDITION,  ACCESS  PERSONS ARE  REMINDED  THAT THEY MAY NOT
          KNOWINGLY  TRADE  PARALLEL  TO OR  AGAINST  A CLIENT  IN A  REPORTABLE
          SECURITY AT ANY TIME OR IN ANY AMOUNT.

          (ii) To  transactions  in Client accounts that are effected by a third
          party  adviser  (or  sub-adviser)  of which an  Access  Person  has no
          knowledge.

          (iii) To transactions in Client accounts that are effected in response
          to  programmed  trading  designed,  for  example,  to align a Client's
          investment portfolio with the performance of a market index.

     5. APPROVAL PERIOD.  Generally,  a pre-clearance is good until the close of
     the business/trading day following the day clearance is granted;  provided,
     however,  the CCO or his designee may shorten or rescind any approval if he
     or she determines it is appropriate to do so. IT IS NECESSARY TO RE-REQUEST
     PRE-CLEARANCE  FOR  TRANSACTIONS  THAT ARE NOT EXECUTED WITHIN THE APPROVAL
     PERIOD.


VI.  ADMINISTRATION, RECORDKEEPING AND ENFORCEMENT


     A.   COMPLIANCE TRAINING PROGRAM AND SUPERVISORY PROCEDURES
     MSA's CCO is  responsible  for  developing  a compliance  training  program
     designed to ensure that all  personnel who are subject to the Statement are

     responsibilities  under  it. In  addition,  MSA's  CCO is  responsible  for
     developing  written compliance  supervisory  procedures that are reasonably
     designed to prevent, detect and correct violations of the Statement.  MSA's

     Act, this Statement, any material changes to the Statement and policies and
     procedures  reasonably  designed  to enforce  its  provisions  and  prevent
     violations,  all as they relate to the Fund's and to MSA in its capacity as
     the Fund's  investment  adviser.  The CCO or his designee shall review,  at
     least annually,  the adequacy of the Statement and the effectiveness of its
     implementation.


                                       12

     C.   INTERPRETATIONS AND WAIVERS
     As to each Company,  the Chief Compliance  Officer, to the extent he or she
     is  vested  individually  or  jointly  with the  necessary  discretion  and
     authority,  may  interpret  issues  and  waive or  except  compliance  with
     provisions  of the  Statement if he or she finds that such  interpretation,
     waiver or exception (i) is necessary to alleviate undue  hardship,  in view
     of unforeseen circumstance, or is otherwise appropriate under the facts and
     circumstances; (ii) is not inconsistent with the purposes and objectives of
     the  Statement;  (iii)  will not  adversely  affect  the  interests  of any
     Clients,  the Companies or their affiliates;  and (iv) will not result in a
     transaction or conduct that would violate  applicable  law,  regulations or
     fiduciary principles.  Any waiver,  exception or interpretation shall be in
     writing stating the basis therefore, and shall be maintained with the books
     and records of the Company.

     D.   REPORTING TO FUND BOARD AND SENIOR MANAGEMENT; ANNUAL CERTIFICATION
     Consistent  with the  provisions  of Rule 17j-1 of the 1940 Act,  the Chief
     Compliance  Officers  of the Fund  and MSA in its  capacity  as the  Fund's
     investment adviser,  shall provide a written report, at least annually,  to
     the Fund's board of directors  that  describes any issues arising under the
     Statement as it applies to the entity and any related  procedures since the
     last such report including,  but not limited to, information about material
     violations and sanctions  imposed in response  thereto,  and any waivers or
     exceptions  during the reporting period of provisions of the Statement that
     might be considered important by the board. Similar reporting shall be made
     by MSA's Chief Compliance Officer to MSA senior management.

     In addition,  the Chief  Compliance  Officer of the Fund and MSA shall also
     certify  annually  in  writing  that  the  entity  has  adopted  procedures
     reasonably   necessary  to  prevent   Access  Persons  from  violating  the
     Statement.

     E.   REPORTING OF VIOLATIONS OF THE STATEMENT
     Access Persons  subject to the Statement are required to report promptly to
     the  CCO  violations  of the  Statement,  including,  but not  limited  to,
     pre-clearance  and  reporting  violations.  All  reports  shall be  treated
     confidentially  to the extent permitted by applicable law, and investigated
     promptly and appropriately. Alternatively, reports may be submitted THROUGH
     the Ethics Resource Center of Northwestern Mutual to help ensure anonymity.
     This is in addition to any reporting  obligations  that Access  Persons may
     have under other policies or any voluntary  reporting of information to the
     Ethics Resource Center. Any retaliation against an individual who reports a
     violation  is  prohibited  and  constitutes  a  further  violation  of  the
     Statement.

     F.   VIOLATIONS OF THE STATEMENT
     Compliance  with the Statement is a condition of employment for each Access
     Person,  and any  violation  of the  Statement  may result in  disciplinary
     action  including,  but not  limited  to  warnings,  fines,  disgorgements,
     suspensions,  demotions, and termination of employment or other association
     with a Company or any of its  affiliates.  In addition to these  sanctions,
     violations may result in referral to civil or criminal authorities.


                                       13

     If a violation or potential  violation  of the  Statement by an  individual
     comes to the attention of the CCO, he shall be required to investigate  the
     matter,  which may include a meeting with the  individual,  if appropriate.
     Upon  completion  of the  investigation,  the CCO may confer with others if
     appropriate  or  required  in order to  determine  whether and what type of
     remedial action should be taken. If disgorgement is required as a result of
     a  violation,  the  proceeds  shall be donated to the  Northwestern  Mutual
     Foundation,  unless  the  violation  resulted  from  personal  trades  that
     directly conflicted with those of Clients, in which case the proceeds shall
     be paid directly to such Clients.

     G.   RECORDKEEPING.

          1.  RECORDS  UNDER THE  ADVISERS  ACT.  The CCO shall  ensure that the
