AN OVERVIEW OF THE FUND WHAT IS THE FUND'S INVESTMENT OBJECTIVE? The fund seeks high total return by investing in high-quality, non-dollar-denominated government and corporate debt securities outside the United States. WHAT ARE THE FUND'S PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS? The fund invests all of its assets in high-quality debt securities, at least 80% of which are issued by foreign corporations and governments. The advisor expects the fund's dollar-weighted average maturity to range from two to 10 years. The fund's primary investment risks include * FOREIGN SECURITIES RISK - Foreign securities have certain unique risks, such as currency risk, political and economic risk, and foreign market and trading risk. * INTEREST RATE RISK - Generally, when interest rates rise, the value of the fund's debt securities will decline. The opposite is true when interest rates decline. * NONDIVERSIFICATION - The fund is classified as NONDIVERSIFIED. This gives the portfolio managers the flexibility to hold large positions in a smaller number of securities. If so, a price change in any one of those securities may have a greater impact on the fund's share price 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. * 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 be 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 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

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 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 Investor Class shares. After-tax returns for other
share classes will vary.

The benchmarks are unmanaged indices that have no operating costs and are
included in the table for performance comparison.

The J.P. Morgan Global Traded Government Bond Index (JPM GTGBI) is a
market-capitalization weighted index consisting of regularly traded, fixed-rate
government bonds from certain developed foreign countries in North America,
Europe, Asia, and Australia. Since January 1998, the fund benchmark has been the
JPM GTGBI with the U.S. excluded and Japan weighted at 15%. Prior to January
1998, the fund benchmark was the J.P. Morgan ECU-Weighted European Index.

OBJECTIVES, STRATEGIES AND RISKS




WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks high total return by investing in high-quality,
non-dollar-denominated government and corporate debt securities outside the
United States.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund invests all of its assets in HIGH-QUALITY DEBT SECURITIES, at least 80%
of which are non-dollar-denominated foreign government and foreign corporate
debt securities. The fund may change this 80% policy only upon 60 days' prior
written notice to shareholders.

     [GRAPHIC OF TRIANGLE]

     HIGH-QUALITY DEBT SECURITIES ARE FIXED-INCOME INVESTMENTS, SUCH AS NOTES,
     BONDS, COMMERCIAL PAPER AND DEBENTURES, THAT HAVE BEEN RATED BY AN
     INDEPENDENT RATING AGENCY IN ITS TOP TWO CREDIT QUALITY CATEGORIES OR
     DETERMINED BY THE ADVISOR TO BE OF COMPARABLE CREDIT QUALITY. THE DETAILS
     OF THE FUND'S CREDIT QUALITY STANDARDS ARE DESCRIBED IN THE STATEMENT OF
     ADDITIONAL INFORMATION.

The portfolio manager, who is responsible for selecting the fund's investments,
determines whether to buy and sell securities for the fund by using a
combination of fundamental research and bond and currency valuation models.

*  ECONOMIC/POLITICAL FUNDAMENTALS. The portfolio manager evaluates each
   country's economic climate and political discipline for controlling deficits
   and inflation.

*  EXPECTED RETURN. Using economic forecasts, the portfolio manager projects
   the expected return for each country.

*  RELATIVE VALUE. By contrasting expected risks and returns for investments
   in each country, the portfolio manager selects those countries expected to
   produce the best return at reasonable risk.

Generally, the fund will purchase only bonds denominated in foreign currencies.
Because the fund is designed for U.S. investors seeking currency and interest
rate diversification, the fund limits its use of hedging strategies that may
minimize the effect of currency fluctuations. The fund may hedge up to 25% of
its total assets into U.S. dollars when the portfolio manager considers the
dollar to be attractive relative to foreign currencies.

The fund also may invest in futures contracts and foreign currency exchange
contracts, provided that such investments are in keeping with the fund's
investment objective.

The weighted average maturity of the fund is expected to be between two and 10
years.

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?

Investing in foreign securities has certain unique risks that make it generally
riskier than investing in U.S. securities. These risks are summarized below.

*  CURRENCY RISK. In addition to changes in the value of the fund's
   investments, changes in the value of foreign currencies against the U.S.
   dollar also could result in gains or losses to the fund. The value of a share
   of the fund is determined in U.S. dollars. The fund's investments, however,
   generally are held in the foreign currency of the country where investments
   are made. As a result, the fund could recognize a gain or loss based solely
   upon a change in the exchange rate between the foreign currency and the U.S.
   dollar.

*  POLITICAL AND ECONOMIC RISK. The fund invests in foreign debt securities,
   which are generally riskier than U.S. debt securities. As a result, the fund
   is subject to foreign political and economic risk not associated with U.S.
   investments, meaning that political events (civil unrest, national elections,
   changes in political conditions and foreign relations, imposition of exchange
   controls and repatriation restrictions), social and economic events (labor
   strikes, rising inflation) and natural disasters occurring in a country where
   the fund invests could cause the fund's investments in that country to
   experience gains or losses. The fund also could be unable to enforce its
   ownership rights or pursue legal remedies in countries where it invests.

*  FOREIGN MARKET AND TRADING RISK. The trading markets for many foreign
   securities are not as active as U.S. markets and may have less governmental
   regulation and oversight. Foreign markets also may have clearance and
   settlement procedures that make it difficult for the fund to buy and sell
   securities. These factors could result in a loss to the fund by causing the
   fund to be unable to dispose of an investment or to miss an attractive
   investment opportunity, or by causing fund assets to be uninvested for some
   period of time.

*  AVAILABILITY OF INFORMATION. Generally, foreign companies are not subject
   to the regulatory controls or uniform accounting, auditing and financial
   reporting standards imposed on U.S. issuers. As a result, there may be less
   publicly available information about foreign issuers than is available
   regarding U.S. issuers.

When interest rates change, the fund's share value will be affected. Generally,
when interest rates rise, the fund's share value will decline. The opposite is
true when interest rates decline. The interest rate risk for International Bond
is higher than for funds that have shorter weighted average maturities, such as
money market and short-term bond funds.

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.

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.

BASICS OF FIXED-INCOME INVESTING

DEBT SECURITIES

When a fund buys a debt security, also called a fixed-income security, it is
essentially lending money to the security's issuer. Notes, bonds, commercial
paper and debentures are examples of debt securities. After the debt security is
first sold by the issuer, it may be bought and sold by other investors. The
price of the debt security may rise or fall based on many factors, including
changes in interest rates, liquidity and credit quality.

The portfolio manager decides which debt securities to buy and sell by

*  determining which debt securities help a fund meet its maturity
   requirements

*  identifying debt securities that satisfy a fund's credit quality standards

*  evaluating the current economic conditions and assessing the risk of
   inflation

*  evaluating special features of the debt securities that may make them more
   or less attractive

WEIGHTED AVERAGE MATURITY

Like most loans, debt securities eventually must be repaid or refinanced at some
date. This date is called the maturity date. The number of days left to a debt
security's maturity date is called the remaining maturity. The longer a debt
security's remaining maturity, generally the more sensitive its price is to
changes in interest rates.

Because a bond fund will own many debt securities, the portfolio manager
calculates the average of the remaining maturities of all the debt securities
the fund owns to evaluate the interest rate sensitivity of the entire portfolio.
This average is weighted according to the size of the fund's individual holdings
and is called the weighted average maturity. The following chart shows how the
portfolio manager would calculate the weighted average maturity for a fund that
owned only two debt securities.

TYPES OF RISK

The basic types of risk the fund faces are described below.

Interest Rate Risk

Generally, interest rates and the prices of debt securities move in opposite
directions. When interest rates fall, the prices of most debt securities rise;
when interest rates rise, prices fall. Because the fund invests primarily in
debt securities, changes in interest rates will affect the fund's performance.
This sensitivity to interest rate changes is called interest rate risk.

The degree to which interest rate changes affect a fund's performance varies and
is related to the weighted average maturity of a particular fund. For example,
when interest rates rise, you can expect the share value of a long-term bond
fund to fall more than that of a short-term bond fund. When rates fall, the
opposite is true.

The following table shows the likely effect of a 1% (100 basis points) increase
in interest rates on the price of 7% coupon bonds of differing maturities:



REMAINING MATURITY   CURRENT PRICE   PRICE AFTER 1% INCREASE   CHANGE IN PRICE

Credit Risk

Credit risk is the risk that an obligation won't be paid and a loss will result.
A high credit rating indicates a high degree of confidence by the rating
organization that the issuer will be able to withstand adverse business,
financial or economic conditions and make interest and principal payments on
time. Generally, a lower credit rating indicates a greater risk of non-payment.
A lower rating also may indicate that the issuer has a more senior series of
debt securities, which means that if the issuer has difficulties making its
payments, the more senior series of debt is first in line for payment.

The portfolio manager does not invest solely on the basis of a debt security's
credit rating; he also considers other factors, including potential returns.
Higher credit ratings usually mean lower interest rate payments, so investors
often purchase debt securities that aren't the highest rated to increase return.
If a fund purchases lower-rated debt securities, it assumes additional credit
risk.

Credit quality may be lower when the issuer has a high debt level, a short
operating history, a difficult, competitive environment, or a less stable cash
flow.

Liquidity Risk

Debt securities can become difficult to sell, or less liquid, for a variety of
reasons, such as lack of an active trading market. The chance that a fund will
have difficulty selling its debt securities is called liquidity risk.

MANAGEMENT

WHO MANAGES THE FUND?

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

THE BOARD OF TRUSTEES

The Board of Trustees oversees the management of the fund and meets at least
quarterly to review reports about fund operations. Although the Board of
Trustees does not manage the fund, it has hired an investment advisor to do so.
More than three-fourths of the trustees 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 J.P. Morgan Investment Management, Inc.
(JPMIM) to make the day-to-day investment decisions for the fund. JPMIM performs
this function under the supervision of the fund's Board of Trustees. JPMIM and
its predecessor companies have managed investments for clients for over eighty
years. JPMIM is headquartered at 245 Park Avenue, New York, New York 10167.

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 management fee is calculated daily and paid monthly in
arrears. Out of the fund's fee, the advisor pays all expenses of managing and
operating the fund except brokerage expenses, taxes, interest, fees and expenses
of the independent trustees (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 percentage rate used to calculate the management fee for each class of
shares of the fund is determined daily using a two-component formula that takes
into account (i) the daily net assets of the accounts managed by the advisor
that are in the same broad investment category as the fund (the "Category Fee")
and (ii) the assets of all funds in the American Century family of funds (the
"Complex Fee"). The statement of additional information contains detailed
information about the calculation of the fund's management fee.

A discussion regarding the basis for the Board of Trustees' approval of the
fund's investment advisory contract with the advisor is available in the fund's
report to shareholders dated June 30, 2006.

THE PORTFOLIO MANAGER

JPMIM employs a portfolio manager to manage the fund. The portfolio manager
regularly reviews portfolio holdings and buys and sells securities for the fund
as he sees fit, guided by the fund's investment objective and strategy.

The portfolio manager who is primarily responsible for the day-to-day management
of the fund is identified below.

JON B. JONSSON

Mr. Jonsson, Vice President and Head of Global Short Duration and London Broad
Market Portfolio Management, has been a member of the team since August 2006. He
joined J.P. Morgan in 1998 and became a portfolio manager in 2001. He has a
bachelor's degree in applied mathematics from the University of Iceland and a
master's degree with specialization in financial engineering from New York
University's Stern School of Business.

The statement of additional information provides additional information about
the other accounts managed by the portfolio manager, if any, 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 objective of the fund may not be changed without
shareholder approval. The Board of Trustees and/or the advisor may change any
other policies and investment strategies.

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 Advisor Class shares are intended for purchase by participants in
employer-sponsored retirement or savings 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 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). 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 your
purchase funds have


------
15


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.


------
16


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 Trustees 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.


------
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. In addition, American Century's ability to monitor trades
that are placed by individual shareholders within group, or omnibus, accounts
maintained by financial intermediaries is severely limited because American
Century generally does not have access to the underlying shareholder account
information. However, American Century monitors aggregate trades placed in
omnibus accounts and seeks to work with financial intermediaries to discourage
shareholders from engaging in abusive trading practices and to impose
restrictions on excessive trades. There may be limitations on the ability of
financial intermediaries to impose restrictions on the trading practices of
their clients. As a result, American Century's ability to monitor and discourage
abusive trading practices in omnibus accounts may be limited.

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 fund's NAV 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. 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.

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 at its fair value as
determined in good faith by, or in accordance with procedures adopted by, the
fund's board or its designee (a process referred to as "fair valuing" the
security). Circumstances that may cause the fund to fair 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.

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.


------
19


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 a fund, as well as CAPITAL GAINS realized by
a 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 of substantially all its income each year. These
distributions may be paid quarterly, but may be paid less frequently.
Distributions from realized capital gains are paid twice a year, usually in
March and December. It may make more frequent distributions, if necessary, to
comply with Internal Revenue Code provisions. Distributions may be taxable as
ordinary income, capital gains or a combination of the two. Capital gains are
taxed at different rates depending on the length of time the fund held the
securities that were sold.

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 a
qualified employer-sponsored retirement or savings 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 a 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 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 three 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. Different fees and expenses will affect performance.

Except as described below, all classes of shares of a 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 shares have a 12b-1 plan. Under the plan,
the fund's Advisor Class pays an annual fee of 0.50% of Advisor Class average
net assets, half for certain ongoing shareholder and administrative services and
half for distribution services, including past distribution services. The
distributor pays all or a portion of such fees to the financial intermediaries
that make Advisor Class shares available. Because these fees are used to pay for
services that are not related to prospective sales of the fund, the Advisor
Class will continue to make payments under the 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 for various additional services or other
expenses out of their profits or other available sources. Such payments may be
made for one or more of the following: (1) distribution services, which 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 intermediary for their sales activities; (2) shareholder
services, such as providing individual and custom investment advisory services
to clients of the intermediary; 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 ensuring that they are educated about the
fund, and to help such intermediaries defray 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.

   reinvestment of all distributions

*  EXPENSE RATIO - the operating expenses of the fund as a percentage of
   average net assets

*  NET INCOME RATIO - the net investment income of the fund as a percentage
   of average net assets

*  PORTFOLIO TURNOVER - the percentage of the fund's investment portfolio
   that is replaced during the period

In October 1996, it changed its name to American Century International Bond Funds. Throughout this statement of additional information we refer to American Century International Bond Funds as the trust. The fund is a separate series of the trust and operates for many purposes as if it were an independent company. The fund's ticker symbols and inception dates of each class of the fund are: FUND/CLASS TICKER SYMBOL INCEPTION DATE -------------------------------------------------------------------------------- International Bond Investor Class BEGBX 01/07/1992 -------------------------------------------------------------------------------- Institutional Class AIDIX 08/02/2004 -------------------------------------------------------------------------------- Advisor Class AIBDX 10/27/1998 -------------------------------------------------------------------------------- FUND INVESTMENT GUIDELINES This section explains the extent to which the fund's advisor, American Century Investment Management, Inc., can use various investment vehicles and strategies in managing the 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 3. In the case of the fund's principal investment strategies, these descriptions elaborate upon the discussion contained in the prospectus. The fund is nondiversified as defined in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total assets, the 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). Nondiversified means that a fund may invest a greater percentage of its assets in a smaller number of securities than a diversified fund. To meet federal tax requirements for qualification as a regulated investment company, the 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. PORTFOLIO COMPOSITION The portfolio manager intends to keep the fund fully invested in foreign debt securities. Under normal market conditions, the fund will invest at least 65% of its total assets in bonds issued or guaranteed by foreign governments or their agencies and by foreign authorities, provinces and municipalities. The fund may invest up to 35% of its total assets in high-quality (i.e., rated "AA" or higher) foreign corporate debt securities. The fund's investments may include but shall not be limited to: (1) debt obligations issued or guaranteed by (a) a foreign sovereign government or one of its agencies, authorities, instrumentalities or political subdivisions including a foreign state, province or municipality, and (b) supranational organizations such as the World Bank, Asian Development Bank, European Investment Bank, and European Economic Community; (2) debt obligations of (a) foreign banks and bank holding companies, and (b) domestic ------ 2 banks and corporations issued in foreign currencies; and (3) foreign corporate debt securities and commercial paper. All of these investments must satisfy the credit quality standards (i.e., "AA" or higher) established by the trustees of the fund. The fund's credit quality requirements effectively limit the countries in which the fund may invest. As of the date of this statement of additional information, the fund expects to invest in the securities of issuers located in and governments of the following countries: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Liechtenstein, Luxembourg, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, Taiwan and the United Kingdom. To limit the possibility that the fund will become unduly concentrated in Japan, the fund currently limits its investment in issuers located in Japan to no more than 25% of total assets. Some securities will also have the country of issue reported as 'Supranational.' These are organizations that cannot be aligned with one particular country, such as the International Finance Corporation or the European Development Bank. For an explanation of the securities ratings referred to in the prospectus and this statement of additional information, see EXPLANATION OF FIXED-INCOME SECURITIES RATINGS on page 43. CURRENCY MANAGEMENT The rate of exchange between U.S. dollars and foreign currencies fluctuates, which results in gains and losses to the fund. Even if the fund's foreign security holdings perform well, an increase in the value of the dollar relative to the currencies in which portfolio securities are denominated can offset net investment income. Because the fund is designed for U.S. investors seeking currency and interest rate diversification, the fund's subadvisor, J.P. Morgan Investment Management Inc. (JPMIM), limits its use of hedging strategies intended to minimize the effect of currency fluctuations. Although hedging strategies (if they are successful) reduce exchange rate risk, they also reduce the potential for share price appreciation when foreign currencies increase in value relative to the U.S. dollar. When the subadvisor considers the U.S. dollar to be attractive relative to foreign currencies, as much as 25% of the fund's total assets may be hedged into U.S. dollars. For temporary defensive purposes and under extraordinary circumstances (such as significant political events), more than 25% of the fund's total assets may be hedged in this manner. In managing the fund's currency exposure, the subadvisor will buy and sell foreign currencies regularly, either in the spot (i.e., cash) market or the forward market. Forward foreign currency exchange contracts (forward contracts) are individually negotiated and privately traded between currency traders (usually large commercial banks) and their customers. In most cases, no deposit requirements exist, and these contracts are traded at a net price without commission. Forward contracts involve an obligation to purchase or sell a specific currency at an agreed-upon price on a future date. Most contracts expire in less than one year. The fund also may use futures and options for currency management purposes. For more information on futures and options, please see FUTURES AND OPTIONS on page 6. FUND INVESTMENTS AND RISKS INVESTMENT STRATEGIES AND RISKS This section describes investment vehicles and techniques the portfolio manager can use in managing the fund's assets. It also details the risks associated with each, because each investment vehicle and technique contributes to the fund's overall risk profile. ------ 3 Foreign Currency Exchange Transactions The fund expects to exchange dollars for the fund's underlying currencies, and vice versa, in the normal course of managing the fund's underlying investments. The fund's subadvisor does not expect that the fund will hold currency that is not earning income on a regular basis, although the fund may do so temporarily when suitable investments are not available. The fund may purchase and sell currencies on a spot basis (i.e., for prompt delivery and settlement), or by entering into forward currency exchange contracts (also called forward contracts) or other contracts to purchase and sell currencies for settlement at a future date. The fund will incur costs in converting assets from one currency to another. Foreign exchange dealers may charge a fee for conversion; in addition, they realize a profit based on the difference (i.e., the spread) between the prices at which they buy and sell various currencies in the spot and forward markets. Thus, a dealer may offer to sell a foreign currency to the fund at one rate and repurchase it at a lesser rate should the fund desire to resell the currency to the dealer. The fund may use foreign currency forward contracts to increase exposure to a foreign currency, or to shift exposure to the fluctuations in the value of foreign currencies from one foreign currency to another foreign currency. Open positions in forwards used for non-hedging purposes will be covered by the segregation of liquid assets, marked to market daily. Forward contracts are agreements to exchange a specific amount of one currency for a specified amount of another at a future date. The date may be any agreed fixed number of days in the future. The amount of currency to be exchanged, the price at which the exchange will take place, and the date of the exchange are negotiated when the fund enters into the contract and are fixed for the term of the contract. Forward contracts are traded in an interbank market conducted directly between currency traders (usually large commercial banks) and their customers. A forward contract generally has no deposit requirement and is consummated without payment of any commission. However, the fund may enter into forward contracts with deposit requirements or commissions. At the maturity of a forward contract, the fund may complete the contract by paying for and receiving the underlying currency, or may seek to roll forward its contractual obligation by entering into an offsetting transaction with the same currency trader and paying or receiving the difference between the contractual exchange rate and the current exchange rate. The fund also may be able to enter into an offsetting contract prior to the maturity of the underlying contract. This practice is sometimes referred to as "cross hedging" and may be employed if, for example, JPMIM believes that one foreign currency (in which a portion of the fund's foreign currency holdings are denominated) will change in value relative to the U.S. dollar differently than another foreign currency. There is no assurance that offsetting transactions, or new forward contracts, will always be available to the fund. Investors should realize that the use of forward contracts does not eliminate fluctuations in the underlying prices of the securities. Such contracts simply establish a rate of exchange that the fund can achieve at some future point in time. Additionally, although such contracts tend to minimize the risk of loss due to fluctuations in the value of the hedged currency when used as a hedge against foreign currency declines, at the same time they tend to limit any potential gain that might result from the change in the value of such currency. Because investments in, and redemptions from, the fund will be in U.S. dollars, JPMIM expects that the fund's normal investment activity will involve a significant amount of currency exchange. For example, the fund may exchange its underlying foreign currencies for U.S. dollars in order to meet shareholder redemption requests or to pay expenses. These transactions may be executed in the spot or forward markets. In addition, the fund may combine forward transactions in its underlying currency with investments in U.S. dollar-denominated instruments, in an attempt to construct an investment position whose overall performance will be similar to that of a security denominated in its underlying currency. If the amount of dollars to be exchanged is ------ 4 properly matched with the anticipated value of the dollar-denominated securities, the fund should be able to lock in the foreign currency value of the securities, and the fund's overall investment return from the combined position should be similar to the return from purchasing a foreign currency-denominated instrument. This is sometimes referred to as a synthetic investment position or a position hedge. The execution of a synthetic investment position may not be successful. It is impossible to forecast with absolute precision what the market value of a particular security will be at any given time. If the value of a dollar-denominated security is not exactly matched with the fund's obligation under the forward contract on the contract's maturity date, the fund may be exposed to some risk of loss from fluctuation of the dollar. Although JPMIM will attempt to hold such mismatchings to a minimum, there can be no assurance that JPMIM will be successful in doing so. Foreign Securities Investments in foreign securities may present certain risks, including: CURRENCY RISK - The value of the foreign investments held by the fund 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 between various currencies in order to purchase and sell foreign securities, and by currency restrictions, exchange control regulation, currency devaluations and political developments. Please see CURRENCY MANAGEMENT on page 3 for more information. POLITICAL AND ECONOMIC RISK - The economies of many of the countries in which the fund invests 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 fund 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 fund 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 fund invests 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 fund are uninvested and no return is earned. The inability of the fund to make intended security purchases due to ------ 5 clearance and settlement problems could cause the fund to miss attractive investment opportunities. Inability to dispose of portfolio securities due to clearance and settlement problems could result either in losses to the fund 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. Futures and Options The 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 the 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 the fund's exposure to market fluctuations, the use of futures contracts may be a more effective means of hedging this exposure. While the 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 the 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 manager 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 Morgan Stanley Capital International Europe, Australasia, Far East Index (MSCI EAFE) and Morgan Stanley Capital International Emerging Markets Free Index (MSCI EMF). The portfolio manager 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. Domestic 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 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 bond, 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 ------ 6 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 debt securities 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. Purchasing Put and Call Options By purchasing a put option, the fund obtains the right (but not the obligation) to sell the option's underlying instrument at a fixed strike price. In return for this right, the fund pays the current market price for the option (known as the option premium). Options have various types of underlying instruments, including specific securities, indices of securities prices, and futures contracts. The fund may terminate its position in a put option it has purchased by allowing it to expire or by exercising the option. If the option is allowed to expire, the fund will lose the entire premium it paid. If the fund exercises the option, it completes the sale of the underlying instrument at the strike price. The fund also may terminate a put option position by closing it out in the secondary market at its current price if a liquid secondary market exists. The buyer of a typical put option can expect to realize a gain if security prices fall substantially. However, if the underlying instrument's price does not fall enough to offset the cost of purchasing the option, a put buyer can expect to suffer a loss (limited to the amount of the premium paid, plus related transaction costs). The features of call options are essentially the same as those of put options, except that the purchaser of a call option obtains the right to purchase, rather than sell, the underlying instrument at the option's strike price. A call buyer typically attempts to participate in potential price increases of the underlying instrument with risk limited to the cost of the option if security prices fall. At the same time, the buyer can expect to suffer a loss if security prices do not rise sufficiently to offset the cost of the option. Writing Put and Call Options If the fund writes a put option, it takes the opposite side of the transaction from the option's purchaser. In return for receipt of the premium, the fund assumes the obligation to pay the strike price for the option's underlying instrument if the other party chooses to exercise the option. When writing an option on a futures contract, the fund will be required to make margin payments to a broker or custodian as described above for futures contracts. The fund may seek to terminate its position in a put option it writes before exercise by closing out the option in the secondary market at its current price. However, if the secondary market is not liquid for a put option the fund has written, the fund must continue to be prepared to pay the strike price while the option is outstanding, regardless of price changes, and must continue to set aside assets to cover its position. If security prices rise, a put writer would generally expect to profit, although the gain would be limited to the amount of the premium received. If security prices remain the same over time, the writer also would likely profit by being able to close out the option at a lower price. If security prices fall, the put writer would expect to suffer a loss. This loss should be less than the loss from purchasing the underlying instrument directly, however, because the premium received for writing the option should mitigate the effects of the decline. ------ 7 Writing a call option obligates the fund to sell or deliver the option's underlying instrument in return for the strike price upon exercise of the option. The characteristics of writing call options are similar to those of writing put options, except that writing calls generally is a profitable strategy if prices remain the same or fall. Through receipt of the option premium, a call writer mitigates the effects of a price decline. At the same time, because a call writer must be prepared to deliver the underlying instrument in return for the strike price even if its current value is greater, a call writer gives up some ability to participate in security price increases. Combined Positions The fund may purchase and write options in combination with one another, or in combination with futures or forward contracts, to adjust the risk and return characteristics of the overall position. For example, the fund may purchase a put option and write a call option on the same underlying instrument to construct a combined position whose risk and return characteristics are similar to selling a futures contract. Another possible combined position would involve writing a call option at one strike price and buying a call option at a lower price to reduce the risk of the written call option in the event of a substantial price increase. Because combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out. Over-the-Counter Options Unlike exchange-traded options, which are standardized with respect to the underlying instrument, expiration date, contract size, and strike price, the terms of over-the-counter (OTC) options (options not traded on exchanges) generally are established through negotiation with the other party to the option contract. While this type of arrangement allows the fund greater flexibility to tailor an option to its needs, OTC options generally involve greater credit risk than exchange-traded options, which are guaranteed by the clearing organizations of the exchanges where they are traded. The risk of illiquidity also is greater with OTC options because these options generally can be closed out only by negotiation with the other party to the option. 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 manager applies a hedge at an inappropriate time or judges interest rate trends incorrectly, futures and options strategies may lower a fund's return. The 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 manager considers 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 manager would not otherwise elect to do so. In addition, the fund may be required to deliver or take delivery of instruments underlying futures contracts it holds. The portfolio manager will seek to minimize these risks by limiting the futures contracts entered into on behalf of the fund to those traded on national futures exchanges and for which there appears to be a liquid secondary market. The 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 the fund had different maturities than those of the portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which the fund loses money on a futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. The fund also could lose margin payments it has deposited with a margin broker if, for example, the broker became bankrupt. ------ 8 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, the 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. The 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. Correlation of Price Changes Because there are a limited number of types of exchange-traded futures and options contracts, it is likely that the standardized contracts available will not match the fund's current or anticipated investments exactly. The fund may invest in futures and options contracts based on securities with different issuers, maturities, or other characteristics from the securities in which it typically invests (for example, by hedging intermediate-term securities with a futures contract based on an index of long-term bond prices); this involves a risk that the futures position will not track the performance of the fund's other investments. Options and futures prices can diverge from the prices of their underlying instruments even if the underlying instruments correlate well with the fund's investments. Options and futures prices are affected by factors such as current and anticipated short-term interest rates, changes in volatility of the underlying instrument, and the time remaining until expiration of the contract, which may not affect security prices the same way. Imperfect correlation also may result from differing levels of demand in the options and futures markets and securities markets, from structural differences in how options and futures and securities are traded, or from the imposition of daily price fluctuation limits or trading halts. The fund may purchase or sell options and futures contracts with a greater or lesser value than the securities it wishes to hedge or intends to purchase in an effort to compensate for differences in volatility between the contract and the securities, although this may not be successful in all cases. If price changes in the fund's options or futures positions are poorly correlated with its other investments, the positions may fail to produce anticipated gains or result in losses that are not offset by gains in other investments. Futures and Options Contracts Relating to Foreign Currencies The fund may purchase and sell currency futures and purchase and write currency options to increase or decrease its exposure to different foreign currencies. The fund also may purchase and write currency options in connection with currency futures or forward contracts. Currency futures contracts are similar to forward currency exchange contracts, except that they are traded on exchanges and have standard contract sizes and delivery dates. Most currency futures contracts call for payment or delivery in U.S. dollars. The uses and risks of currency futures are similar to those of futures relating to securities or indices, as described above. Currency futures values can be expected to correlate with exchange rates but may not reflect other factors that affect the value ------ 9 of the fund's investments. A currency hedge, for example, should protect a German-mark-denominated security from a decline in the German mark, but it will not protect the fund against a price decline resulting from a deterioration in the issuer's creditworthiness. Liquidity of Futures Contracts and Options There is no assurance that a liquid secondary market will exist for any particular futures contract or option at any particular time. Options may have relatively low trading volume and liquidity if their strike prices are not close to the underlying instrument's current price. In addition, exchanges may establish daily price fluctuation limits for futures contracts and options and may halt trading if a contract's price moves upward or downward more than the limit on a given day. On volatile trading days when the price fluctuation limit is reached or a trading halt is imposed, it may be impossible for the fund to enter into new positions or close out existing positions. If the secondary market for a contract was not liquid, because of price fluctuation limits or otherwise, prompt liquidation of unfavorable positions could be difficult or impossible, and the fund could be required to continue holding a position until delivery or expiration regardless of changes in its value. Under these circumstances, the fund's access to assets held to cover its future positions also could be impaired. Futures and options trading on foreign exchanges may not be regulated as effectively as similar transactions in the U.S. and may not involve clearing mechanisms or guarantees similar to those available in the U.S. The value of a futures contract or option traded on a foreign exchange may be adversely affected by the imposition of different exercise and settlement terms, trading procedures, margin requirements and lesser trading volume. Restrictions on the Use of Futures Contracts and Options The fund may enter into futures contracts, options or options on futures contracts. Under the Commodity Exchange Act, the fund may enter into futures and options transactions (a) for hedging purposes without regard to the percentage of assets committed to initial margin and option premiums or (b) for purposes other than hedging, provided that assets committed to initial margin and option premiums do not exceed 5% of the fund's total assets. To the extent required by law, the 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. Other Investment Companies The fund 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 * 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 the 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 the 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 ------ 10 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, the fund may lend its portfolio securities. Such loans may not exceed one-third of the fund's total net 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 The 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 the fund. A repurchase agreement occurs when, at the time the 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. The fund 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 pursuant to criteria adopted by the fund's advisor. Repurchase agreements maturing in more than seven days would count toward the fund's 15% limit on illiquid securities. Short-Term Securities In order to meet anticipated redemptions, anticipated purchases of additional securities for the fund's portfolio, or, in some cases, for temporary defensive purposes, the 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; * Commercial Paper; * Certificates of Deposit and Euro Dollar Certificates of Deposit; * Bankers' Acceptances; * Short-term notes, bonds, debentures or other debt instruments; * Repurchase agreements; and * Money market funds. ------ 11 U.S. Government Securities The fund may invest in U.S. government securities including bills, notes and bonds issued by the U.S. Treasury and securities issued or guaranteed by agencies or instrumentalities of the U.S. government. Some U.S. government securities are supported by the direct full faith and credit of the U.S. government; others are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as securities issued by the Federal National Mortgage Association (FNMA), are supported by the discretionary authority of the U.S. government to purchase the agencies' obligations; and others are supported only by the credit of the issuing or guaranteeing instrumentality. There is no assurance that the U.S. government will provide financial support to an instrumentality it sponsors when it is not obligated by law to do so. When-Issued and Forward Commitment Agreements The fund 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 the 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. 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. ------ 12 INVESTMENT POLICIES Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the policies described below apply at the time the fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified limitation resulting from a change in the fund's assets will not be considered in determining whether it has complied with its investment policies. Fundamental Investment Policies The fund's fundamental investment policies are set forth below. These investment policies and the fund's investment objective set forth in its prospectus may not be changed without approval of a majority of the outstanding votes of shareholders of the fund, as determined in accordance with the Investment Company Act. SUBJECT POLICY -------------------------------------------------------------------------------- Senior The fund may not issue senior securities, except as permitted Securities under the Securities Investment Company Act. -------------------------------------------------------------------------------- Borrowing The fund may not borrow money, except that the 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 The 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 The 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 The fund 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 The 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 The 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 The fund may not invest for purposes of exercising control over management. -------------------------------------------------------------------------------- For purposes of the investment policies relating to lending and borrowing, the fund has received an exemptive order from the SEC regarding an interfund lending program. Under the terms of the exemptive order, the fund 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 fund 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 fund will lend through the program only when the returns are higher than those available from other short-term instruments (such as repurchase agreements). The fund 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. ------ 13 For purposes of the investment policy relating to concentration, the 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, (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 fund is subject to the following investment policies that are not fundamental and may be changed by the Board of Trustees. SUBJECT POLICY -------------------------------------------------------------------------------- Leveraging The fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the fund. -------------------------------------------------------------------------------- Liquidity The 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 in securities that are illiquid by virtue of legal or contractual restrictions on resale or the absence of a readily available market. -------------------------------------------------------------------------------- Short Sales The 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 The 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 The fund may enter into futures contracts and write and buy and Options put and call options relating to futures 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 with A fund may invest a portion of its assets in the securities of Limited issuers with limited operating histories. An issuer is Operating considered to have a limited operating history if that issuer Histories 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. -------------------------------------------------------------------------------- The Investment Company Act imposes certain additional restrictions upon the fund's 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 fund or its investment practices or policies. ------ 14 TEMPORARY DEFENSIVE MEASURES For temporary defensive purposes, the fund may invest in securities that may not fit its investment objective or its stated market. During a temporary defensive period, the fund may direct its assets to the following investment vehicles: * interest-bearing bank accounts or Certificates of Deposit; * U.S. government securities and repurchase agreements collateralized by U.S. government securities; and * money market funds. To the extent the fund assumes a defensive position, it will not be pursuing its investment objective. PORTFOLIO TURNOVER The portfolio turnover rate of the fund is listed in the FINANCIAL HIGHLIGHTS table in the prospectus. The portfolio manager will sell securities without regard to the length of time the security has been held. Accordingly, the fund's rate of portfolio turnover may be substantial. The portfolio manager intends to purchase a particular security whenever he believes it will contribute to the stated objective of the fund. In order to achieve the fund's investment objective, the portfolio manager 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 manager may sell a portfolio security if he believes that the security is not fulfilling its purpose because, among other things, it did not live up to the manager's 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. Because investment decisions are based on a particular security's anticipated contribution to the fund's objectives, the manager believes that the rate of portfolio turnover is irrelevant when he determines that a change is required to pursue the fund's investment objective. As a result, the fund's annual portfolio turnover rate cannot be anticipated and may be higher than other mutual funds with similar investment objectives. Portfolio turnover also may affect the character of capital gains realized and distributed by the fund, if any, since short-term capital gains are taxable as ordinary income. Because the manager does not take portfolio turnover rate into account in making investment decisions, (1) the manager has 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. 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 manager's investment outlook. TRANSACTIONS WITH SUBADVISOR AFFILIATES As described in further detail under the section titled INVESTMENT ADVISOR, J.P. Morgan Investment Management, Inc. (JPMIM) is the subadvisor to the fund pursuant to an agreement with American Century Investment Management, Inc. The subadvisor, a wholly owned subsidiary of J.P. Morgan Chase & Co. (J.P. Morgan Chase) and a corporation organized under the laws of the State of Delaware, is a registered investment adviser under the Investment Advisers Act of 1940, as amended. The subadvisor is located at 245 Park Avenue, New York, New York 10167. ------ 15 J.P. Morgan Chase, a bank holding company organized under the laws of the State of Delaware, was formed from the merger of J.P. Morgan & Co. Incorporated with and into The Chase Manhattan Corporation. J.P. Morgan Chase, together with its predecessors, has been in the banking and investment advisory business for over 100 years and today, through JPMIM and its other subsidiaries (such as, Morgan Guaranty Trust Company of New York [Morgan Guaranty], J. P. Morgan Securities Inc., and J.P. Morgan Securities Ltd.), offers a wide range of banking and investment management services to governmental, institutional, corporate and individual clients. These subsidiaries are hereafter referred to as Morgan affiliates. J.P. Morgan Securities Inc. is a broker-dealer registered with the SEC and is a member of the National Association of Securities Dealers. It is active as a dealer in U.S. government securities and an underwriter of and dealer in U.S. government agency securities and money market instruments. J.P. Morgan Securities Ltd. underwrites, distributes, and trades international securities, including Eurobonds, commercial paper, and foreign government bonds. J.P. Morgan Chase issues commercial paper and long-term debt securities. Morgan Guaranty and some of its affiliates issue certificates of deposit and create bankers' acceptances. The fund will not invest in securities issued or created by a Morgan affiliate. Certain activities of Morgan affiliates may affect the fund's portfolio or the markets for securities in which the fund invests. In particular, activities of Morgan affiliates may affect the prices of securities held by the fund and the supply of issues available for purchase by the fund. Where a Morgan affiliate holds a large portion of a given issue, the price at which that issue is traded may influence the price of similar securities the fund holds or is considering purchasing. The fund will not purchase securities directly from Morgan affiliates, and the size of Morgan affiliates' holdings may limit the selection of available securities in a particular maturity, yield, or price range. The fund will not execute any transactions with Morgan affiliates and will use only unaffiliated broker-dealers. In addition, the fund will not purchase any securities of U.S. government agencies during the existence of an underwriting or selling group of which a Morgan affiliate is a member, except to the extent permitted by law. The fund's ability to engage in transactions with Morgan affiliates is restricted by the SEC and the Federal Reserve Board. In JPMIM's opinion, these limitations should not significantly impair the fund's ability to pursue its investment objectives. However, there may be circumstances in which the fund is disadvantaged by these limitations compared to other funds with similar investment objectives that are not subject to these limitations. In acting for its fiduciary accounts, including the fund, JPMIM will not discuss its investment decisions or positions with the personnel of any Morgan affiliate. JPMIM has informed the fund that, in making investment decisions, it will not obtain or use material, non-public information in the possession of any division or department of JPMIM or other Morgan affiliates. The commercial banking divisions of Morgan Guaranty and its affiliates may have deposit, loan, and other commercial banking relationships with issuers of securities the fund purchases, including loans that may be repaid in whole or in part with the proceeds of securities purchased by the fund. Except as may be permitted by applicable law, the fund will not purchase securities in any primary public offering when the prospectus discloses that the proceeds will be used to repay a loan from Morgan Guaranty. JPMIM will not cause the fund to make investments for the direct purpose of benefiting other commercial interests of Morgan affiliates at the fund's expense. ------ 16 MANAGEMENT The individuals listed below serve as trustees or officers of the fund. Each trustee serves until his or her successor is duly elected and qualified or until he or she retires. Effective March 2004, mandatory retirement age for independent trustees is 73. However, the mandatory retirement age may be extended for a period not to exceed two years with the approval of the remaining independent trustees. Those listed as interested trustees 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 fund's investment advisor, American Century Investment Management, Inc. (ACIM or the advisor); the fund's principal underwriter, American Century Investment Services, Inc. (ACIS); and the fund's transfer agent, American Century Services, LLC (ACS). The other trustees (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 trustees serve in this capacity for eight registered investment companies in the American Century family of funds. All persons named as officers of the fund also serve in similar capacities for the other 14 investment companies 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 fund. The listed officers are interested persons of the fund and are appointed or re-appointed on an annual basis.

Although the Board of Trustees does not manage the fund, it has hired the advisor to do so. The trustees, in carrying out their fiduciary duty under the Investment Company Act of 1940, are responsible for approving new and existing management contracts with the fund's advisor. The board has the authority to manage the business of the fund on behalf of their investors, and it has all powers necessary or convenient to carry out that responsibility. Consequently, the trustees may adopt bylaws providing for the regulation and management of the affairs of the fund and may amend and repeal them to the extent that such bylaws do not reserve that right to the fund's 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 trustees who may exercise the powers and authority of the board to the extent that the trustees determine. They may, in general, delegate such authority as they consider desirable to any officer of the fund, to any committee of the board and to any agent or employee of the fund or to any custodian, transfer or investor servicing agent, or principal underwriter. Any determination as to what is in the interests of the fund made by the trustees in good faith shall be conclusive. The Advisory Board The fund also has an Advisory Board. Members of the Advisory Board, if any, function like fund trustees in many respects, but do not possess voting power. Advisory Board members attend all meetings of the Board of Trustees and the independent trustees 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 Trustees. ------ 19 Committees The board has four standing committees to oversee specific functions of the funds' operations. Information about these committees appears in the table below. The trustee first named serves as chairman of the committee. -------------------------------------------------------------------------------- COMMITTEE: Audit and Compliance MEMBERS: Jeanne D. Wohlers, Ronald J. Gilson, Peter F. Pervere(1) FUNCTION: The Audit and Compliance Committee approves the engagement of the funds' independent registered public accounting firm, recommends approval of such engagement to the independent trustees, 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: Corporate Governance MEMBERS: Ronald J. Gilson, John Freidenrich, John B. Shoven FUNCTION: The Corporate Governance Committee reviews board procedures and committee structures. It also considers and recommends individuals for nomination as trustees.

Shareholders may submit trustee nominations to the Corporate Secretary, American Century Funds, P.O. Box 410141, Kansas City, MO 64141. All such nominations will be forwarded to the committee for consideration. The committee also may recommend the creation of new committees, evaluate the membership structure of new and existing committees, consider the frequency and duration of board and committee meetings and otherwise evaluate the responsibilities, processes, resources, performance and compensation of the board. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 1 -------------------------------------------------------------------------------- COMMITTEE: Portfolio MEMBERS: Myron S. Scholes, John Freidenrich, Kathryn A. Hall FUNCTION: The Portfolio Committee reviews quarterly the investment activities and strategies used to manage fund assets. The committee regularly receives reports from portfolio managers, credit analysts and other investment personnel concerning the funds' investments.

It receives and reviews reports comparing those services to those of fund competitors and seeks to improve such services where feasible and appropriate. NUMBER OF MEETINGS HELD DURING LAST FISCAL YEAR: 5 -------------------------------------------------------------------------------- (1) ADVISORY BOARD MEMBER. Compensation of Trustees The trustees serve as trustees for eight American Century investment companies. Each trustee 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 fund 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 fund is responsible for paying such fees and expenses. The following table shows the aggregate compensation paid by the fund for the periods indicated and by the investment companies served by the board to each trustee who is not an interested person as defined in the Investment Company Act. ------ 20 AGGREGATE TRUSTEE COMPENSATION FOR FISCAL YEAR ENDED DECEMBER 31, 2006 -------------------------------------------------------------------------------- TOTAL COMPENSATION TOTAL FROM THE COMPENSATION AMERICAN CENTURY NAME OF TRUSTEE FROM THE FUND(1) FAMILY OF FUNDS(2) -------------------------------------------------------------------------------- Antonio Canova(3) $5,212 $40,917 -------------------------------------------------------------------------------- John Freidenrich $12,105 $100,250 -------------------------------------------------------------------------------- Ronald J.

The fund has adopted the American Century Mutual Funds' Independent Directors Deferred Compensation Plan. Under the plan, the independent trustees may defer receipt of all or any part of the fees to be paid to them for serving as trustees of the fund. All deferred fees are credited to an account established in the name of the trustees. 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 trustee. 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. Trustees are allowed to change their designation of mutual funds from time to time. No deferred fees are payable until such time as a trustee resigns, retires or otherwise ceases to be a member of the Board of Trustees. Trustees 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 trustee, all remaining deferred fee account balances are paid to the trustee's beneficiary or, if none, to the trustee's estate. The plan is an unfunded plan and, accordingly, the fund has no obligation to segregate assets to secure or fund the deferred fees. To date, the fund has voluntarily funded its obligations. The rights of trustees to receive their deferred fee account balances are the same as the rights of a general unsecured creditor of the fund. 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. ------ 21 OWNERSHIP OF FUND SHARES The trustees owned shares in the fund as of December 31, 2006, 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 fund, 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 fund. In exercising its voting obligations, the advisor is guided by general fiduciary principles. It must act prudently, solely in the interest of the fund, and for the exclusive purpose of providing benefits to it. The advisor attempts to consider all factors of its vote that could affect the value of the investment. The fund's Board of Trustees 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 fund. In particular, the proxy voting guidelines outline principles and factors to be considered in the exercise of voting authority for proposals addressing: * Election of Directors * Ratification of Selection of Auditors * Equity-Based Compensation Plans * Anti-Takeover Proposals * Cumulative Voting * Staggered Boards ------ 22 * "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 fund. To ensure that such a conflict of interest does not affect proxy votes cast for the fund, all discretionary (including case-by-case) voting for these companies will be voted in direct consultation with a committee of the independent trustees of the 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 Web site at sec.gov. 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. ------ 23 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 fund's 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 fund's 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. Those parties who have entered into non-disclosure agreements as of March 12, 2007 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. * Cleary Gull Inc. * Commerce Bank, N.A. * Connecticut General Life Insurance Company * 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 ------ 24 * 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 * 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 DW, Inc. * 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. ------ 25 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. 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 fund and the fund's advisor must have access to some or all of the fund's 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 fund's 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 fund's Board of Trustees exercises oversight of disclosure of the fund's 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. ------ 26 THE FUND'S PRINCIPAL SHAREHOLDERS As of April 3, 2007, the following shareholders, beneficial or of record, owned more than 5% of the outstanding shares of any class of the fund: PERCENTAGE OF PERCENTAGE OF OUTSTANDING OUTSTANDING SHARES OWNED SHARES OWNED FUND/CLASS SHAREHOLDER OF RECORD BENEFICIALLY(1) -------------------------------------------------------------------------------- International Bond -------------------------------------------------------------------------------- Investor Charles Schwab & Co. Inc. San Francisco, California 25% 0% Citigroup Global Markets Inc. New York, New York 18% 0% National Financial Services Corp.

OTHERWISE, AMERICAN CENTURY HAS NO INFORMATION CONCERNING BENEFICIAL OWNERSHIP OF FUND SHARES. The fund is unaware of any other shareholders, beneficial or of record, who own more than 5% of any class of the fund's outstanding shares. A shareholder owning of record or beneficially more than 25% of the trust's outstanding shares may be considered 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. Although Charles Schwab & Co., Inc., San Francisco, CA, is the record owner of more than 25% of the shares of the trust, it is not a control person because it is not the beneficial owner of such shares. The fund is unaware of any other shareholders, beneficial or of record, who own more than 25% of the voting securities of the trust. As of April 3, 2007, the officers and trustees of the fund, as a group, owned less than 1% of any class of the fund's outstanding shares. ------ 27 SERVICE PROVIDERS The fund has no employees. To conduct its day-to-day activities, the trust has hired a number of service providers. Each service provider has a specific function to fill on behalf of the fund 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 the fund. Currently, JPMIM serves as the subadvisor for the fund. A description of the responsibilities of the advisor (ACIM or JPMIM) appears in the prospectus under the heading MANAGEMENT. For the services provided to the fund, the advisor receives a unified management fee based on a percentage of the net assets of the fund. For more information about the unified management fee, see THE INVESTMENT ADVISOR under the heading MANAGEMENT in the fund's prospectus. The annual rate at which this fee is assessed is determined daily in a multi-step process. First, the trust's fund is categorized according to the broad asset class in which it invests (e.g., money market, bond or equity), and the assets of the fund in each category are totaled ("Fund Category Assets"). Second, the assets are totaled for certain other accounts managed by the advisor ("Other Account Category Assets"). To be included, these accounts must have the same management team and investment objective as a fund in the same category with the same Board of Trustees as the trust. Together, the Fund Category Assets and the Other Account Category Assets comprise the "Investment Category Assets." The Investment Category Fee Rate is then calculated by applying the fund's Investment Category Fee Schedule to the Investment Category Assets and dividing the result by the Investment Category Assets. Finally, a separate Complex Fee Schedule is applied to the assets of all of the funds in the American Century family of funds (the "Complex Assets"), and the Complex Fee Rate is calculated based on the resulting total. The Investment Category Fee Rate and the Complex Fee Rate are then added to determine the Management Fee Rate payable by a class of the fund to the advisor. For purposes of determining the assets that comprise the Fund Category Assets, Other Account Category Assets and Complex Assets, the assets of registered investment companies managed by the advisor that invest primarily in the shares of other registered investment companies shall not be included. The schedules by which the unified management fee is determined are shown below. INVESTMENT CATEGORY FEE SCHEDULE FOR INTERNATIONAL BOND CATEGORY ASSETS FEE RATE -------------------------------------------------------------------------------- First $1 billion 0.6100% -------------------------------------------------------------------------------- Next $1 billion 0.5580% -------------------------------------------------------------------------------- Next $3 billion 0.5280% -------------------------------------------------------------------------------- Next $5 billion 0.5080% -------------------------------------------------------------------------------- Next $15 billion 0.4950% -------------------------------------------------------------------------------- Next $25 billion 0.4930% -------------------------------------------------------------------------------- Thereafter 0.4925% -------------------------------------------------------------------------------- ------ 28 The Complex Fee is determined according to the schedule below. COMPLEX FEE SCHEDULE INVESTOR ADVISOR INSTITUTIONAL CLASS CLASS CLASS COMPLEX ASSETS FEE RATE FEE RATE FEE RATE -------------------------------------------------------------------------------- First $2.5 billion 0.3100% 0.0600% 0.1100% -------------------------------------------------------------------------------- Next $7.5 billion 0.3000% 0.0500% 0.1000% -------------------------------------------------------------------------------- Next $15 billion 0.2985% 0.0485% 0.0985% -------------------------------------------------------------------------------- Next $25 billion 0.2970% 0.0470% 0.0970% -------------------------------------------------------------------------------- Next $25 billion 0.2870% 0.0370% 0.0870% -------------------------------------------------------------------------------- Next $25 billion 0.2800% 0.0300% 0.0800% -------------------------------------------------------------------------------- Next $25 billion 0.2700% 0.0200% 0.0700% -------------------------------------------------------------------------------- Next $25 billion 0.2650% 0.0150% 0.0650% -------------------------------------------------------------------------------- Next $25 billion 0.2600% 0.0100% 0.0600% -------------------------------------------------------------------------------- Next $25 billion 0.2550% 0.0050% 0.0550% -------------------------------------------------------------------------------- Thereafter 0.2500% 0.0000% 0.0500% -------------------------------------------------------------------------------- On each calendar day, each class of the fund accrues a management fee that is equal to the class's Management Fee Rate times the net assets of the class divided by 365 (366 in leap years). On the first business day of each month, the fund pays a management fee to the advisor for the previous month. The fee for the previous month is the sum of the calculated daily fees for each class of the fund during the previous month. The management agreement between the trust 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 fund's Board of Trustees, or a majority of outstanding shareholder votes (as defined in the Investment Company Act); and (2) the vote of a majority of the trustees of the fund 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 fund's Board of Trustees 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 that the advisor shall not be liable to the fund or its 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, trustees or 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 fund and also for other clients advised by the advisor or the subadvisor. Investment decisions for the fund 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 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 ------ 29 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 the fund. The subadvisor may aggregate purchase and sale orders of the fund with purchase and sale orders of its other clients when the subadvisor believes that such aggregation provides the best execution for the fund. The Board of Trustees has approved the policy of the advisor and subadvisor with respect to the aggregation of portfolio transactions. Unified management fees incurred by the fund for the fiscal periods ended December 31, 2006, 2005 and 2004, are indicated in the following table. UNIFIED MANAGEMENT FEES FUND 2006 2005 2004 -------------------------------------------------------------------------------- International Bond $10,145,324 $9,511,642 $5,792,890 -------------------------------------------------------------------------------- SUBADVISOR The investment management agreement provides that the advisor may delegate certain responsibilities under the agreement to a subadvisor. Currently, JPMorgan Investment Management, Inc. ("JPMIM") serves as subadvisor to the fund under a subadvisory agreement between ACIM and JPMIM dated August 1, 1997, that was approved by shareholders on July 30, 1997. This supersedes subadvisory agreements dated June 1, 1995, June 1, 1994 and December 31, 1991. The subadvisory agreement continues for an initial period of two years and thereafter so long as continuance is specifically approved by vote of a majority of the fund's outstanding voting securities or by vote of a majority of the fund's trustees, including a majority of those trustees 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 Trustees, or a majority of the fund's outstanding shareholder votes or 12 months' written notice by JPMIM and will terminate automatically in the event of (i) its assignment or (ii) termination of the investment advisory agreement between the fund and the advisor. The subadvisory agreement provides that JPMIM will make investment decisions for the fund in accordance with the fund's investment objective, policies, and restrictions, and whatever additional written guidelines it may receive from the advisor from time to time. For these services, the advisor pays JPMIM a monthly fee at an annual rate of 0.20% of the fund's average daily net assets up to $200 million; and 0.15% of average daily net assets over $200 million. Under the 1991 subadvisory agreement, the advisor paid JPMIM a monthly fee at an annual rate of 0.25% of average daily net assets up to $200 million, and 0.05% of average daily net assets in excess of $200 million, with a minimum annual fee of $250,000. For the fiscal years ended December 31, 2006, 2005 and 2004, the advisor paid JPMIM subadvisory fees as listed in the following table: JPMIM SUBADVISORY FEES -------------------------------------------------------------------------------- 2006 $2,042,061 -------------------------------------------------------------------------------- 2005 $1,921,553 -------------------------------------------------------------------------------- 2004 $1,075,322 -------------------------------------------------------------------------------- ------ 30 PORTFOLIO MANAGER The information provided under this heading has been provided by the subadvisor. Other Accounts Managed The portfolio manager also is responsible for the day-to-day management of other accounts, as indicated by the following table. OTHER ACCOUNTS MANAGED (AS OF DECEMBER 31, 2006) REGISTERED OTHER POOLED INVESTMENT INVESTMENT OTHER COMPANIES VEHICLES(1) ACCOUNTS(1) -------------------------------------------------------------------------------- International Bond -------------------------------------------------------------------------------- Number of Other Accounts Jon B. Managed 3 42 38 Jonsson ----------------------------------------------------------------------- Assets in Other Accounts Managed $755.52 million $19,097 million $12,276 million -------------------------------------------------------------------------------- (1) TWO OF THE 42 OTHER POOLED INVESTMENT VEHICLES, TOTALING $26.87 MILLION IN ASSETS, AND SIX OF THE 38 OTHER ACCOUNTS, TOTALING $2,685 MILLION IN ASSETS, HAVE AN ADVISORY FEE THAT IS BASED ON THE PERFORMANCE OF THE ACCOUNT. Potential Conflicts of Interest The chart above shows the number, type and market value as of December 30, 2006, of the accounts other than the fund that are managed by the fund's portfolio manager. The potential for conflicts of interest exists when portfolio managers manage other accounts with similar investment objectives and strategies as the fund ("Similar Accounts"). Potential conflicts may include, for example, conflicts between investment strategies and conflicts in the allocation of investment opportunities. Responsibility for managing client portfolios of the subadvisor and its affiliates is organized according to investment strategies within asset classes. Generally, client portfolios with similar strategies are managed by portfolio managers in the same portfolio management group using the same objectives, approach and philosophy. Underlying sectors or strategy allocations within a larger portfolio are likewise managed by portfolio managers who use the same approach and philosophy as similarly managed portfolios. Therefore, portfolio holdings, relative position sizes and industry and sector exposures tend to be similar across similar portfolios and strategies, which minimizes the potential for conflicts of interest. The subadvisor and/or its affiliates may receive more compensation with respect to certain Similar Accounts than that received with respect to the fund or may receive compensation based in part on the performance of certain Similar Accounts. This may create a potential conflict of interest for the subadvisor and its affiliates or its portfolio managers by providing an incentive to favor these Similar Accounts when, for example, placing securities transactions. In addition, the subadvisor or its affiliates could be viewed as having a conflict of interest to the extent that the subadvisor or an affiliate has a proprietary investment in Similar Accounts, the portfolio managers have personal investments in Similar Accounts or the Similar Accounts are investment options in the subadvisor's and its affiliates' employee benefit plans. Potential conflicts of interest may arise with both the aggregation and allocation of securities transactions and allocation of limited investment opportunities because of market factors or investment restrictions imposed upon the subadvisor and its affiliates by law, regulation, contract or internal policies. Allocations of aggregated trades, particularly trade orders that were only partially completed due to limited availability, and allocation of investment opportunities generally, could raise a potential conflict of interest, as the subadvisor or its affiliates may have an incentive to allocate securities that are expected to increase in value to favored accounts. Initial public offerings, in particular, are frequently of very limited availability. The subadvisor and its affiliates may be perceived as causing accounts they manage to participate in an offering to increase the subadvisor's or its affiliates overall allocation of securities in that offering. ------ 31 A potential conflict of interest also may be perceived to arise if transactions in one account closely follow related transactions in a different account, such as when a purchase increases the value of securities previously purchased by another account, or when a sale in one account lowers the sale price received in a sale by a second account. If the subadvisor or its affiliates manage accounts that engage in short sales of securities of the type in which the fund invests, the subadvisor could be seen as harming the performance of the fund for the benefit of the accounts engaging in short sales if the short sales cause the market value of the securities to fall. As an internal policy matter, the subadvisor may from time to time maintain certain overall investment limitations on the securities positions or positions in other financial instruments the subadvisor or its affiliates will take on behalf of its various clients due to, among other things, liquidity concerns and regulatory restrictions. It should be recognized that such policies may preclude an account from purchasing particular securities or financial instruments, even if such securities or financial instruments would otherwise meet the account's objectives. The goal of the subadvisor and its affiliates is to meet their fiduciary obligation with respect to all clients. The subadvisor and its affiliates have policies and procedures designed to manage the conflicts. The subadvisor and its affiliates monitor a variety of areas, including compliance with fund guidelines, review of allocation decisions and compliance with JPMorgan's Codes of Ethics and JPMC's Code of Conduct. With respect to the allocation of investment opportunities, the subadvisor and its affiliates also have certain policies designed to achieve fair and equitable allocation of investment opportunities among its clients over time. For example: Orders for the same equity security are aggregated on a continual basis throughout each trading day consistent with the subadvisor's duty of best execution for its clients. If aggregated trades are fully executed, accounts participating in the trade will be allocated their pro rata share on an average price basis. Partially completed orders generally will be allocated among the participating accounts on a pro-rata average price basis, subject to certain limited exceptions. For example, accounts that would receive a DE MINIMIS allocation relative to their size may be excluded from the order. Another exception may occur when thin markets or price volatility require that an aggregated order be completed in multiple executions over several days. If partial completion of the order would result in an uneconomic allocation to an account due to fixed transaction or custody costs, the subadvisor or its affiliates may exclude small orders until 50% of the total order is completed. Then the small orders will be executed. Following this procedure, small orders will lag in the early execution of the order, but will be completed before completion of the total order. Purchases of money market instruments and fixed income securities cannot always be allocated pro-rata across the accounts with the same investment strategy and objective. However, the subadvisor and its affiliates attempt to mitigate any potential unfairness by basing non-pro rata allocations traded through a single trading desk or system upon an objective predetermined criteria for the selection of investments and a disciplined process for allocating securities with similar duration, credit quality and liquidity in the good faith judgment of the subadvisor so that fair and equitable allocation will occur over time. Compensation The subadvisor's portfolio managers participate in a competitive compensation program that is designed to attract and retain outstanding people and closely link the performance of investment professionals to client investment objectives. The total compensation program includes a base salary fixed from year to year and a variable performance bonus consisting of cash incentives and restricted stock and, in some cases, mandatory deferred compensation. These elements reflect individual performance and the performance of the subadvisor's business as a whole. ------ 32 Each portfolio manager's performance is formally evaluated annually based on a variety of factors including the aggregate size and blended performance of the portfolios such portfolio manager manages. Individual contribution relative to client goals carries the highest impact. Portfolio manager compensation is primarily driven by meeting or exceeding clients' risk and return objectives, relative performance to competitors or competitive indices and compliance with firm policies and regulatory requirements. In evaluating each portfolio manager's performance with respect to the mutual funds he or she manages, the funds' pre-tax performance is compared to the appropriate market peer group and to each fund's benchmark index listed in the fund's prospectus over one, three and five year periods (or such shorter time as the portfolio manager has managed the fund). Investment performance is generally more heavily weighted to the long-term. Awards of restricted stock are granted as part of an employee's annual performance bonus and comprise from 0% to 35% of a portfolio manager's total bonus. As the level of incentive compensation increases, the percentage of compensation awarded in restricted stock also increases. Up to 50% of the restricted stock portion of a portfolio manager's bonus may instead be subject to a mandatory notional investment in selected mutual funds advised by the subadvisor. When these deferred amounts vest, the portfolio manager receives cash equal to the market value of the notional investment in the selected mutual funds. Ownership of Securities The fund's portfolio manager did not beneficially own any shares of the fund as of December 31, 2006, the fund's most recent fiscal year end. TRANSFER AGENT AND ADMINISTRATOR American Century Services, LLC (ACS), 4500 Main Street, Kansas City, Missouri 64111, serves as transfer agent and dividend-paying agent for the fund. It provides physical facilities, computer hardware and software and personnel, for the day-to-day administration of the fund and the advisor. The advisor pays ACS's costs for serving as transfer agent and dividend-payment agent for the fund out of the advisor's unified management fee. For a description of this fee and the terms of its payment, see the above discussion under the caption INVESTMENT ADVISOR on page 28. From time to time, special services may be offered to shareholders who maintain higher share balances in our family of funds. These services may include the waiver of minimum investment requirements, expedited confirmation of shareholder transactions, newsletters and a team of personal representatives. Any expenses associated with these special services will be paid by the advisor. DISTRIBUTOR The fund's shares are distributed by American Century Investment Services, Inc. (ACIS), a registered broker-dealer. The distributor is a wholly owned subsidiary of ACC, and its principal business address is 4500 Main Street, Kansas City, Missouri 64111. The distributor is the principal underwriter of the fund's shares. The distributor makes a continuous, best-efforts underwriting of the fund's shares. This means the distributor has no liability for unsold shares. The advisor pays ACIS's costs for serving as principal underwriter of the fund's shares out of the advisor's unified management fee. For a description of this fee and the terms of its payment, see the above discussion under the caption INVESTMENT ADVISOR on page 28. ACIS does not earn commissions for distributing the fund's shares. Certain financial intermediaries unaffiliated with the distributor or the fund may perform various administrative and shareholder services for their clients who are invested in the fund. These services may include assisting with fund purchases, redemptions and exchanges, distributing information about the fund and its ------ 33 performance, preparing and distributing client account statements, and other administrative and shareholder services that would otherwise be provided by the distributor or its affiliates. The distributor may pay fees out of its own resources to such financial intermediaries for providing these services. CUSTODIAN BANKS State Street Bank and Trust Company, 801 Pennsylvania Avenue, Kansas City, Missouri 64105, and Commerce Bank, N.A., 1000 Walnut, Kansas City, Missouri 64105, each serves as custodian of the fund's assets. State Street also performs certain investment accounting and recordkeeping functions on behalf of the fund. The custodians take no part in determining the investment policies of the fund or in deciding which securities are purchased or sold by the fund. The fund, however, may invest in certain obligations of the custodians and may purchase or sell certain securities from or to the custodians. INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM PricewaterhouseCoopers LLP is the independent registered public accounting firm of the fund. The address of PricewaterhouseCoopers LLP is 1055 Broadway, 10th Floor, Kansas City, Missouri 64105. As the independent registered public accounting firm of the fund, PricewaterhouseCoopers LLP provides services including: (1) auditing the annual financial statements for the fund, (2) assisting and consulting in connection with SEC filings, and (3) reviewing the annual federal income tax return filed for the fund. BROKERAGE ALLOCATION Under the management agreement between the fund and the advisor, and under the subadvisory agreement between the advisor and the subadvisor, the subadvisor has the responsibility of selecting brokers and dealers to execute portfolio transactions. 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 broker or dealer is a function of the selection of market and the negotiation of price, as well as the broker's general execution and operational and financial capabilities in the type of transaction involved. The subadvisor will seek to obtain prompt execution of orders at the most favorable prices or yields. The subadvisor may choose to purchase and sell portfolio securities from and to dealers who provide statistical and other information and services, including research, to the fund and to the subadvisor. Such information or services will be in addition to and not in lieu of the services required to be performed by the subadvisor, and the expenses of the subadvisor will not necessarily be reduced as a result of the receipt of such supplemental information. 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). During the fiscal years ended December 31, 2004, 2005 and 2006, the fund did not pay any brokerage commissions. REGULAR BROKER-DEALERS As of the end of its most recently completed fiscal year, the fund 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. VALUE OF SECURITIES BROKER, DEALER OWNED AS OF FUND OR PARENT DECEMBER 31, 2006 -------------------------------------------------------------------------------- International Bond Barclays Bank plc $13,189,813 -------------------------------------------------------------------------------- ------ 34 INFORMATION ABOUT FUND SHARES The Declaration of Trust permits the Board of Trustees to issue an unlimited number of full and fractional shares of beneficial interest without par value, which may be issued in series (or funds). The fund is a series of shares issued by the trust, and shares of the fund have equal voting rights. 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. Voting rights are not cumulative, so that investors holding more than 50% of the trust's (all funds') outstanding shares may be able to elect a Board of Trustees. The trust undertakes dollar-based voting, meaning that the number of votes a shareholder is entitled to is based upon the dollar amount of the shareholder's investment. The election of trustees is determined by the votes received from all the trust'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. 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. Shares of the fund have equal voting rights. The trust shall continue unless terminated by (1) approval of at least two-thirds of the shares of each fund entitled to vote or (2) the trustees by written notice to shareholders of each fund. Any fund may be terminated by (1) approval of at least two-thirds of the shares of that fund or (2) the trustees by written notice to shareholders of that fund. Upon termination of the trust or a fund, as the case may be, the trust shall pay or otherwise provide for all charges, taxes, expenses and liabilities belonging to the trust or the fund. Thereafter, the trust shall reduce the remaining assets belonging to each fund (or the particular fund) to cash, shares of other securities or any combination thereof, and distribute the proceeds belonging to each fund (or the particular fund) to the shareholders of that fund ratably according to the number of shares of that fund held by each shareholder on the termination date. Shareholders of a Massachusetts business trust could, under certain circumstances, be held personally liable for its obligations. However, the Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the trust. The Declaration of Trust also provides for indemnification and reimbursement of expenses of any shareholder held personally liable for obligations of the trust. The Declaration of Trust provides that the trust will, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the trust and satisfy any judgment thereon. The Declaration of Trust further provides that the trust may maintain appropriate insurance (for example, fidelity, bonding and errors and omissions insurance) for the protection of the trust, its shareholders, trustees, officers, employees and agents to cover possible tort and other liabilities. Thus, the risk of a shareholder incurring financial loss as a result of shareholder liability is limited to circumstances in which both inadequate insurance exists and the trust is unable to meet its obligations. The assets belonging to each series or class of shares are held separately by the custodian and the shares of each series or class represent a beneficial interest in the principal, earnings and profit (or losses) of investments and other assets held for each fund or class. Within their respective series or class, all shares have equal redemption rights. Each share, when issued, is fully paid and non-assessable. ------ 35 MULTIPLE CLASS STRUCTURE The Board of Trustees has adopted a multiple class plan pursuant to Rule 18f-3 adopted by the SEC. The plan is described in the fund's prospectus. Pursuant to such plan, the fund may issue up to three classes of shares: an Investor Class, Institutional Class and Advisor Class. The Investor Class is made available to investors directly without any load or commission, for a single unified management fee. The Institutional and Advisor Classes are made available to institutional shareholders or through financial intermediaries that 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 those classes a lower total management fee. In addition to the management fee, however, Advisor Class shares are subject to an Advisor Class Plan described below. The plan has been adopted by the fund's Board of Trustees and initial shareholder 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 Trustees and approved by its shareholders. Pursuant to such rule, the Board of Trustees and initial shareholder of the fund's Advisor Class have approved and entered into an Advisor Class Plan. The plan is described below. In adopting the plan, the Board of Trustees (including a majority of trustees who are not interested persons of the fund [as defined in the Investment Company Act], hereafter referred to as the independent trustees) determined that there was a reasonable likelihood that the plan would benefit the fund and the shareholders of the affected class. Some of the anticipated benefits include improved name recognition of the fund generally; and growing assets in an existing fund, which helps retain and attract investment management talent, provide a better environment for improving fund performance, and can lower the total expense ratio for funds with stepped-fee schedules. Pursuant to Rule 12b-1, information about revenues and expenses under the plan is presented to the Board of Trustees quarterly for its consideration in continuing the plan. Continuance of the plan must be approved by the Board of Trustees, including a majority of the independent trustees, annually. The plan may be amended by a vote of the Board of Trustees, including a majority of the independent trustees, except that the plan 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 plan terminates automatically in the event of an assignment and may be terminated upon a vote of a majority of the independent trustees or by vote of a majority of the outstanding voting securities of the affected class. All fees paid under the plan will be made in accordance with Section 26 of the Conduct Rules of the National Association of Securities Dealers (NASD). Advisor Class Plan As described in the prospectus, the fund's Advisor Class shares are made available to participants in employer-sponsored retirement or savings plans and to persons purchasing through broker-dealers, banks, insurance companies and other financial intermediaries that provide various administrative, shareholder and distribution services. The fund's distributor enters into contracts with various banks, broker-dealers, insurance companies and other financial intermediaries, with respect to the sale of the fund's shares and/or the use of the fund's shares in various investment products or in connection with various financial services. Certain recordkeeping and administrative services that are provided by the fund's 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. ------ 36 To enable the fund's shares to be made available through such plans and financial intermediaries, and to compensate them for such services, the fund's advisor has reduced its management fee by 0.25% per annum with respect to the Advisor Class shares and the fund's Board of Trustees has adopted a Master Distribution and Shareholder Services Plan (the Advisor Class Plan). Pursuant to the Advisor Class Plan, the Advisor Class pays the fund's distributor a fee of 0.50% annually of the aggregate average daily asset value of the fund's Advisor Class shares, 0.25% of which is paid for ongoing shareholder and administrative services (as described below) and 0.25% of which is paid for distribution services, including past distribution services (described below). This payment is fixed at 0.50% and is not based on expenses incurred by the distributor. 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 for the services described below. No portion of these payments is used by the distributor to pay for advertising, printing costs or interest expenses. During the fiscal year ended December 31, 2006, the aggregate amount of fees paid under the plan was $290,242. Payments may be made for a variety of shareholder services, including, but are not limited to: (a) receiving, aggregating and processing purchase, exchange and redemption requests from beneficial owners of shares (including contract owners of insurance products that utilize the fund as underlying investment media) and placing purchase, exchange and redemption orders with the fund's distributors; (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 the 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 the fund as necessary for such subaccounting; (i) preparing and forwarding investor communications from the fund (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 fund. During the fiscal year ended December 31, 2006, the amount of fees paid under the Advisor Class Plan for shareholder services was $145,121. 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 fund's Advisor Class shares; (c) compensating and paying expenses (including overhead and telephone expenses) of the distributor; ------ 37 (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 fund's 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 investors 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 the provision of personal, continuing services to investors, as contemplated by the Conduct Rules of the NASD; and (n) such other distribution and services activities as the advisor determines may be paid for by the fund pursuant to the terms of the agreement between the trust and the fund's distributor and in accordance with Rule 12b-1 of the Investment Company Act. During the fiscal year ended December 31, 2006, the amount of fees paid under the Advisor Class Plan for distribution services was $145,121. Payments to Dealers 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 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 National Association of Securities Dealers, Inc. Such payments will not change the price paid by investors for shares of the fund. BUYING AND SELLING FUND SHARES Information about buying, selling, exchanging and, if applicable, converting fund shares is contained in the fund's prospectus. The prospectus is available to investors without charge and may be obtained by calling us. American Century considers employer-sponsored retirement plans to include the following: * 401(a) plans * pension plans * profit sharing plans * 401(k) plans * money purchase plans * target benefit plans * Taft-Hartley multi-employer pension plans ------ 38 * SERP and "Top Hat" plans * ERISA trusts * employee benefit trusts * 457 plans * KEOGH plans * employer-sponsored 403(b) plans (including self-directed) * nonqualified deferred compensation plans * nonqualified excess benefit plans * nonqualified retirement plans * SIMPLE IRAs * SEP IRAs * SARSEP Traditional and Roth IRAs are not considered employer-sponsored retirement plans.

EMPLOYER-SPONSORED TRADITIONAL AND RETIREMENT PLANS ROTH IRAS -------------------------------------------------------------------------------- Institutional Class shares may be purchased Yes Yes -------------------------------------------------------------------------------- Investor Class shares may be purchased Yes Yes -------------------------------------------------------------------------------- Advisor Class shares may be purchased Yes Yes -------------------------------------------------------------------------------- VALUATION OF THE FUND'S SECURITIES All classes of the fund are offered at their net asset value, as described below. The 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 fund expects the same holidays to be observed in the future, the NYSE may modify its holiday schedule at any time. The 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. 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 Trustees. The subadvisor typically completes its trading on behalf of the fund in various markets before the NYSE closes for the day. Foreign currency exchange rates also are determined prior to the close of the NYSE. 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 at fair value as determined in accordance with procedures adopted by the Board of Trustees. ------ 39 Securities maturing within 60 days of the valuation date may be valued at cost, plus or minus an amortized discount or premium, unless the trustees 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 at their fair value using methods approved by the Board of Trustees. 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. 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 at fair value as determined in accordance with procedures adopted by the Board of Trustees. 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 fund's 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 fund's portfolios may be affected on days when shares of the fund may not be purchased or redeemed. TAXES FEDERAL INCOME TAX The 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, the 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 the 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 from the fund in the same manner in which they were realized by the fund. 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 fund 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 fund 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 dividends you received on those shares. As of December 31, 2006, the fund had the following capital loss carryover, which expires in the years and amounts listed. When a fund has a capital loss carryover, it does not make capital gains distributions until the loss has been offset or expired. ------ 40 CAPITAL LOSS CARRYOVER FUND 2008 2009 2010 2011 2012 2013 2014 -------------------------------------------------------------------------------- International - - - - - - ($9,602,222) Bond -------------------------------------------------------------------------------- Dividends and interest received by the 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 the fund will reduce its dividends distributions to investors. If more than 50% of the value of the 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 you have not complied with certain provisions of the Internal Revenue Code and Regulations, either American Century or your financial intermediary is required by federal law to withhold and remit to the IRS the applicable federal withholding rate of reportable payments (which may include dividends, capital gains distributions and redemption proceeds). 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 the 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. The fund's transactions in foreign currencies, forward contracts, options and futures contracts (including options and futures contracts on foreign currencies) will be subject to special provisions of the Code that, among other things, may affect the character of gains and losses realized by the fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the fund, defer fund losses, and affect the determination of whether capital gains and losses are characterized as long-term or short-term capital gains or losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also may require the fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were sold), which may cause the fund to recognize income without receiving cash with which to make distributions in amounts necessary to satisfy the 90% and 98% distribution requirements for relief from income and excise taxes, respectively. The fund will monitor its transactions and may make such tax elections as fund management deems appropriate with respect to foreign currency, options, futures contracts or forward contracts. The fund's status ------ 41 as a regulated investment company may limit its transactions involving foreign currency, futures, options and forward contracts. Under the Code, gains or losses attributable to fluctuations in exchange rates that occur between the time the fund accrues income or other receivables or accrues expenses or other liabilities denominated in a foreign currency and the time the fund actually collects such receivables or pays such liabilities generally are treated as ordinary income or loss. Similarly, in disposing of debt securities denominated in foreign currencies, certain forward currency contracts, or other instruments, gains or losses attributable to fluctuations in the value of a foreign currency between the date the security, contract, or other instrument is acquired and the date it is disposed of are also usually treated as ordinary income or loss. Under Section 988 of the Code, these gains or losses may increase or decrease the amount of the fund's investment company taxable income distributed to shareholders as ordinary income. STATE AND LOCAL TAXES Distributions by the fund 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. FINANCIAL STATEMENTS The financial statements of the fund have been audited by PricewaterhouseCoopers LLP, independent registered public accounting firm. Their Report of Independent Registered Public Accounting Firm and the financial statements included in the fund's annual report for the fiscal year ended December 31, 2006, are incorporated herein by reference. ------ 42 EXPLANATION OF FIXED-INCOME SECURITIES RATINGS As described in the prospectus, the fund may invest in fixed-income securities. Those investments, however, are subject to certain credit quality restrictions, as noted in the prospectus. 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 some what 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. -------------------------------------------------------------------------------- ------ 43 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. -------------------------------------------------------------------------------- ------ 44 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 regarding (P-1) 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 commercial paper is (P-2) 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. Issues (P-3) 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; VMIG-1 Notes are of the highest quality enjoying 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; VMIG-2 Notes are of high quality with margins of protection ample, although not so large as in the preceding group. -------------------------------------------------------------------------------- SP-3 MIG-3; VMIG-3 Notes are of favorable quality with all 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; VMIG-4 Notes are of adequate quality carrying specific risk but having protection and not distinctly or predominantly speculative. -------------------------------------------------------------------------------- ------ 45 MORE INFORMATION ABOUT THE FUND IS CONTAINED IN THESE DOCUMENTS Annual and Semiannual Reports Annual and semiannual reports contain more information about the fund's investments and the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period.

TRUST is made as of the 8th day of March, 2007 by the Trustees hereunder.

     WHEREAS, the Board of Trustees have executed an Amendment and Restatement
to the Agreement and Declaration of Trust dated March 26, 2004, and amended June
14, 2004; and

     WHEREAS, pursuant to Article VIII, Section 8 of the Declaration of Trust,
the Trustees wish to amend the Declaration of Trust as follows.

     NOW, THEREFORE, BE IT RESOLVED, the Declaration of Trust is hereby amended
by deleting the present Section 6(d) of Article III and inserting in lieu
thereof the following:

     (d) VOTING. On any matter submitted to a vote of the Shareholders of the
     Trust, all Shares of all Series and Classes then entitled to vote shall be
     voted together, except that (i) when required by the 1940 Act to be voted
     by individual Series or Class, Shares shall be voted by individual Series
     or Class, or (ii) when the matter affects only the interests of
     Shareholders of one or more Series or Classes, only Shareholders of such
     one or more Series or Classes shall be entitled to vote thereon.

     RESOLVED, the Declaration of Trust is hereby amended by deleting the
present Section 3 of Article V and inserting in lieu thereof the following:

     SECTION 3. QUORUM AND REQUIRED VOTE
     Except when a larger quorum is required by applicable law, by the Bylaws or
     by this Declaration of Trust, one-third of the Shares entitled to vote
     shall constitute a quorum at a Shareholders' meeting. When any one or more

     quorum is present at any meeting, a majority of the Shares voted shall
     decide any questions and a plurality shall elect a Trustee, except when a
     larger vote is required by any provision of this Declaration of Trust or
     the Bylaws or by applicable law.

     RESOLVED, the Declaration of Trust is hereby amended by deleting the
present Section 4 of Article VIII and inserting in lieu thereof the following:

     least two-thirds (66 (2)/3%) of the Shares of each Series entitled to vote,
     voting separately by Series, or by the Trustees by written notice to the
     Shareholders. Any Series or Class may be terminated at any time by vote of
     at least two-thirds (66 (2)/3%) of the Shares of that Series or Class, or
     by the Trustees by written notice to the Shareholders of that Series or
     Class.

     Upon termination of the Trust (or any Series or Class, as the case may be),
     after paying or otherwise providing for all charges, taxes, expenses and
     liabilities belonging, severally, to each Series (or the applicable Series
     or Class, as the case may be), whether due or accrued or anticipated as may
     be determined by the Trustees, the Trust shall, in accordance with such
     procedures as the Trustees consider appropriate, reduce the remaining
     assets belonging, severally, to each Series (or the applicable Series or
     Class, as the case may be), to distributable form in cash or shares or
     other securities, or any combination thereof, and distribute the proceeds
     belonging to each Series (or the applicable Series or Class, as the case
     may be), to the Shareholders of that Series or Class, as a Series or Class,
     ratably according to the number of Shares of that Series or Class held by
     the several Shareholders on the date of termination.

     IN WITNESS WHEREOF, the Trustees do hereto set their hands as of the
date written above.

     (b)  Definitions

          (1)  An "INVESTMENT TEAM" is the Portfolio Managers that the
               Investment Manager has designated to manage a given portfolio.

          (2)  An "INVESTMENT STRATEGY" is the processes and policies
               implemented by the Investment Manager for pursuing a particular
               investment objective managed by an Investment Team.

          (3)  A "PRIMARY STRATEGY PORTFOLIO" is each Fund, as well as any other
               series of any other registered investment company for which the
               Investment Manager serves as the investment manager and for which
               American Century Investment Services, Inc. serves as the
               distributor; provided, however, that a registered investment
               company that invests its assets exclusively in the shares of
               other registered investment companies shall not be a Primary
               Strategy Portfolio. Any exceptions to the above requirements
               shall be approved by the Board of Directors.

          (4)  A "SECONDARY STRATEGY PORTFOLIO" is another account managed by
               the Investment Manager that is managed by the same Investment
               Team as that assigned to manage any Primary Strategy Portfolio
               that shares the same board of directors or board of trustees as
               the Company. Any exceptions to this requirement shall be approved
               by the Board of Directors.

          (5)  An "INVESTMENT CATEGORY" for a Fund is the group to which the
               Fund is assigned for determining the first component of its
               management fee. Each Primary Strategy Portfolio is assigned to
               one of the three Investment Categories indicated below. The
               Investment Category assignments for the Funds appear in Schedule
               B to this Agreement. The amount of assets in each of the
               Investment Categories ("INVESTMENT CATEGORY ASSETS") is
               determined as follows:

               a)   MONEY MARKET FUND CATEGORY ASSETS. The assets which are used
                    to determine the fee for this Investment Category is the sum
                    of the assets of all of the Primary Strategy Portfolios and


                                                                          Page 2


                                       AMERICAN CENTURY INTERNATIONAL BOND FUNDS


                    Secondary Strategy Portfolios that invest primarily in debt
                    securities and are subject to Rule 2a-7 under the Investment
                    Company Act.

               b)   BOND FUND CATEGORY ASSETS. The assets which are used to
                    determine the fee for this Investment Category is the sum
                    the assets of all of the Primary Strategy Portfolios and
                    Secondary Strategy Portfolios that invest primarily in debt
                    securities and are not subject to Rule 2a-7 under the
                    Investment Company Act.

               c)   EQUITY FUND CATEGORY ASSETS. The assets which are used to
                    determine the fee for this Investment Category is the sum
                    the assets of all of the Primary Strategy Portfolios and
                    Secondary Strategy Portfolios that invest primarily in
                    equity securities.

          (6)  The "PER ANNUM INVESTMENT CATEGORY FEE DOLLAR AMOUNT" for a Fund
               is the dollar amount resulting from applying the applicable
               Investment Category Fee Schedule for the Fund (as shown on
               Schedule A) using the applicable Investment Category Assets.

          (7)  The "PER ANNUM INVESTMENT CATEGORY FEE RATE" for Fund is the
               percentage rate that results from dividing the Per Annum
               Investment Category Fee Dollar Amount for the Fund by the
               applicable Investment Category Assets for the Fund.

          (8)  The "COMPLEX ASSETS" is the sum of the assets in all of the
               Primary Strategy Portfolios.

          (9)  The "PER ANNUM COMPLEX FEE DOLLAR AMOUNT" for a class of a Fund
               shall be the dollar amount resulting from application of the
               Complex Assets to the Complex Fee Schedule for the class as shown
               in Schedule C.

          (10) The "PER ANNUM COMPLEX FEE RATE" for a class of a Fund is the
               percentage rate that results from dividing the Per Annum Complex
               Fee Dollar Amount for the class of a Fund by the Complex Assets.

          (11) The "PER ANNUM MANAGEMENT FEE RATE" for a class of a Fund is the
               sum of the Per Annum Investment Category Fee Rate applicable to
               the Fund and the Per Annum Complex Fee Rate applicable to the
               class of the Fund.

     (c)  DAILY MANAGEMENT FEE CALCULATION. For each calendar day, each class of
          each Fund shall accrue a fee calculated by multiplying the Per Annum
          Management Fee Rate for that class times the net assets of the class
          on that day, and further dividing that product by 365 (366 in leap
          years).

     (d)  MONTHLY MANAGEMENT FEE PAYMENT. On the first business day of each
          month, each class of each series Fund shall pay the management fee to
          the Investment Manager for the previous month. The fee for the
          previous month shall be the sum of the Daily Management Fee
          Calculations for each calendar day in the previous month.


                                                                          Page 3

     (e)  ADDITIONAL SERIES OR CLASSES. In the event that the Board of Directors
          shall determine to issue any additional series of shares for which it
          is proposed that the Investment Manager serve as investment manager,
          the Company and the Investment Manager shall enter into an Addendum to
          this Agreement setting forth the name of the series and/or classes, as
          appropriate, the Applicable Fee and such other terms and conditions as
          are applicable to the management of such series and/or classes, or, in
          the alternative, enter into a separate management agreement that
          relates specifically to such series or classes of shares.

     vote of a majority of the Directors, who are not parties to the Agreement
     or interested persons of any such party, cast in person at a meeting called

     if given within a period beginning not more than 90 days prior to August
     1st of each applicable year, notwithstanding the fact that more than 365
     days may have elapsed since the date on which such approval was last given.

                             DEALER/AGENCY AGREEMENT


Ladies and Gentlemen:

     American  Century  Investment   Services,   Inc.   ("Distributor")  is  the
distributor  and  American  Century  Services,  LLC  ("Transfer  Agent")  is the
transfer agent  (collectively with the Distributor,  "we" or "us") of the shares
of the American Century family of mutual funds  (collectively,  the "Funds," and
individually,  a "Fund").  Distributor has the right, as agent for the Funds, to
arrange for the sale of shares of the Funds to dealers or the  public,  or both.
We invite you to make shares of the various  classes of the Funds  available  to
your customers upon the following terms and conditions:

     1.  AVAILABILITY OF FUND SHARES.  Distributor  agrees to cause the Funds to
sell  to,  redeem  from and  exchange  for you  shares  of  beneficial  interest
("Shares")  of one or more  classes  of the  Funds,  subject  to the  terms  and
conditions of this Agreement,  each Fund's then-current prospectus and statement
of  additional   information  and  any  supplements  thereto  (collectively  the
"Prospectus"),  any  limitations  imposed by any of the Funds or the  investment
advisor of the Funds. To the extent that a Prospectus  contains  provisions that
are inconsistent  with the terms of this Agreement,  the terms of the Prospectus
shall control.

     2. PURCHASE AND SALE OF FUND SHARES. (a) The public offering price at which
you may offer the Shares is the net asset value  thereof  plus any sales  charge
applicable to such Shares (the "Sales Charge"), as computed from time to time as
described in the then-current Prospectus of the applicable class of the relevant
Fund. You agree to make Shares of the Funds available to your customers  subject
to minimum investment requirements applicable to each order, unless you register
your customer purchases in your name and omnibus account as nominee. You further
acknowledge  and agree  that  tracking  and  application  of any  Sales  Charge,
including any scheduled  variation in, or elimination of, such Sales Charge,  is
your  responsibility  and will be charged uniformly to all offerees in the class
specified  in the  Prospectus.  You  understand  that all orders are  subject to
acceptance or rejection by us or the Funds in the sole discretion of either.

     (b) Each  transaction is always made subject to  confirmation  by us at the
offering  price next computed  after  receipt of the order.  Subject to Sections
2(d), 2(h) and 2(i) below,  orders to purchase,  redeem and exchange Fund Shares
("Orders") received by you prior to the price time for each Fund as set forth in
its Prospectus  (the "Price Time"),  generally the close of regular trading (the


                                       1




"Close of Trading") on the New York Stock Exchange (the "Exchange") on any given
business day (currently  4:00 p.m.  Eastern time) (each a "Business  Day"),  and
transmitted  to the  Transfer  Agent  either (1) prior to the Price Time on such
Business Day or (2) pursuant to the National Securities  Clearing  Corporation's
("NSCC") Mutual Fund Settlement, Entry and Redemption Verification ("Fund/SERV")
system,  and in  accordance  with Section 7 hereof,  will be executed at the net
asset value  determined as of the relevant Fund's Price Time on the Business Day
you received such Order.  Any Orders  transmitted  to the Transfer Agent after a
Fund's  Price Time on a Business  Day will be  executed  at the net asset  value
determined as of that Fund's Price Time on the next Business Day.

     (c) The day as of which an Order is executed pursuant to the provisions set
forth above is referred to as the "Trade Date."

     (d) Any Order by you for the  purchase  of Shares of the Funds  through  us
shall be  accepted  at the time when it is  received  by  Transfer  Agent or any
clearinghouse  agency we may  designate  from time to time,  unless  rejected by
Transfer  Agent.  We will not  accept  any  Order  from you that is  placed on a
conditional basis or is subject to any delay or contingency prior to execution.

     (e) Subject to Section 2(g) hereof,  with respect to the Funds,  the Shares
of which are  indicated  in that  Fund's  Prospectus  as being sold with a Sales
Charge (the "Load Funds"),  you will be allowed the concessions  from the public
offering  price  provided  in  such  Load  Fund's   Prospectus  and/or  periodic
instruction  from us. If a Load Fund is sold but the  front-end  load is waived,
you will not receive any  concession.  With respect to the Funds,  the Shares of
which are  indicated in that Fund's  Prospectus  as being sold with a contingent
deferred sales charge or early withdrawal charge (the "CDSC Funds"), you will be
paid a concession as disclosed in such CDSC Fund's  Prospectus  and/or  periodic
instructions  from us. If a CDSC Fund is sold but the CDSC is  waived,  you will
not receive any concession. All dealer concessions are subject to change without
notice by us and will comply with any changes in  regulatory  requirements.  You
agree  that  you will not  combine  customer  orders  to  reach  breakpoints  in
concessions for any purpose whatsoever unless authorized by the Prospectus or by
us in writing.

     (f) Certain of the classes of certain Funds have adopted distribution plans
pursuant  to  which  Distributor,  on  behalf  of each  such  Fund,  will  pay a
distribution  fee and, for some classes,  a service fee to dealers in accordance
with the provisions of such Funds'  distribution  plans. The service fee is paid
in  accordance  with  Section  2(g)  hereof  as  additional  consideration  for,
depending on the class, all individual  shareholder services,  including account
maintenance services, or administrative services provided by you to shareholders
of the applicable  Fund. The distribution fee is paid to the broker of record as
consideration for the distribution services the broker of record provides to its
clients,  including receiving and answering correspondence,  assisting investors
in  completing  application  forms and  selecting  dividend  and  other  account
options,  providing facilities to answer questions from clients about the Funds,


                                       2



and other past and continuing  services to clients.  The provisions and terms of
these Funds' distribution plans are described in their respective  Prospectuses,
and you hereby agree that we have made no representations to you with respect to
the  distribution  plans of such Funds in addition to, or conflicting  with, the
description set forth in their  respective  Prospectuses.  No dealer discount or
concession  is  applicable  to  Shares  representing  reinvested  dividends  and
distributions. No interest will accrue on amounts represented by uncashed dealer
discount, concession, service fee or distribution fee checks.

     (g)  Notwithstanding  any other provision hereof,  any dealer  concessions,
service fees or other payments described herein shall be paid only to the broker
of record  pursuant to our  records,  whether  that broker is the  executing  or
clearing  broker.  Only one broker may be  designated as the broker of record on
any account.

     (h) Any Order placed by you for the purchase of Shares of a Fund is subject
to the timely receipt by Transfer Agent of all required documents in good order.
If such documents are not received  within a reasonable  time after the Order is
placed,  the Order is  subject  to  cancellation,  in which case you agree to be
responsible for any loss resulting to the Fund or to us from such cancellation.

     (i)  Notwithstanding  Section 2(b) above,  if the  Securities  and Exchange
Commission  ("SEC")  adopts  a  rule,  or a law is  enacted,  that  changes  the
requirements for intermediaries with regard to accepting Orders on behalf of the
Funds,  the timing of  transmitting  Orders to the  Funds'  Transfer  Agent,  or
otherwise  affects the way Orders are accepted,  transmitted or priced,  Section
2(b) shall be deemed to be automatically amended to comply with such new rule or
law.

     (j) You represent and warrant that you will  consider all  guidelines  from
the  National  Association  of  Securities  Dealers  ("NASD")  and the SEC  when
determining  whether a Fund is appropriate for a client, and which class is most
appropriate.  You further  represent and warrant that you will recommend  Shares
only for those clients for whom the investment is suitable according to any such
guidelines current at the time of the recommendation.

     3.  REDEMPTIONS.  If any  Shares of any of the Load Funds sold to you under
the terms of this  Agreement  are  redeemed by the Fund or  repurchased  for the
account of the Funds or are tendered to the Funds for  redemption  or repurchase
within seven (7) Business  Days after the Trade Date of your  original  purchase
order therefor, you agree to pay forthwith to Distributor the full amount of the
concession, if any, allowed to you on the original sale.

     4.  REPRESENTATIONS.  (a) You  represent  that (i) you are  registered as a
broker and/or dealer under the Securities Exchange Act of 1934, as amended,  and
are licensed and qualified as a broker and/or dealer or otherwise  authorized to
offer  and sell the  Shares  under  the laws of each  jurisdiction  in which the
Shares  will be  offered  and sold by you,  or are a bank as  defined in Section
3(a)(6) of the Securities  Exchange Act of 1934, as amended,  and in either case
are  duly  authorized  to  engage  in  the  activities  to be  performed  by you
hereunder;  (ii) your agents and employees  are and will remain duly  registered
and licensed to offer and sell Shares in those jurisdictions in which you do so;


                                       3



and (iii) if you are a  broker/dealer,  you are a member in good standing of the
("NASD") and agree to maintain such membership (or in the alternative,  that you
are a foreign  dealer not required to be an NASD member).  You agree to abide by
all applicable  state and federal laws and the rules and regulations of the SEC,
the NASD,  and any other  authorized  regulatory  agency that are  binding  upon
underwriters   and  dealers  in  the  distribution  of  securities  of  open-end
investment companies, including, without limitation, Rule 2830 (formerly Article
III, Section 26) of the NASD Conduct Rules, all of which are incorporated herein
as if set forth in full,  or you represent  that you are exempt from  compliance
with such laws, rules and  regulations.  You agree not to sell or offer for sale
Shares in any state or jurisdiction  where they have not been qualified for sale
(as  stated  in such  Fund's  then-current  Prospectus)  or in which you are not
qualified as a broker, dealer or bank. You agree to notify us immediately if you
cease to be  registered  or licensed as a broker and/or dealer or fail to remain
as a member  in good  standing  of the NASD,  or if you  cease to be a bank,  as
defined above.

     (b) Should you provide  brokerage  clearing  services to  broker-dealers or
other  financial  intermediaries  who  wish  to sell  Shares  to  their  clients
("Originating Firms"), you represent that you and each such Originating Firm are
parties  to  a  clearing  agreement  which  conforms  in  all  respects  to  the
requirements of Rule 3230 of the NASD Conduct Rules or, as applicable, the rules
of a national  securities  exchange.  In connection  with your provision of such
brokerage  clearing  services,  you  acknowledge  and  agree  that  we  have  no
responsibility  for determining  whether Shares are suitable for clients of your
Originating Firms.

     (b)  Neither  you nor  any  person  associated  with  you  shall  give  any
information or make any representation concerning the Funds or the Shares except
those contained in the then-current  Prospectus or any Sales Materials furnished
by us or the Funds or  approved by us or the Funds in writing in advance for use
in connection  therewith  (except that Sales  Materials  provided by us that are
designated as being for Investment Professional Use Only may not be disseminated
to the public). Any Sales Materials,  if distributed,  must be accompanied by or
preceded by the appropriate Fund's then-current  prospectus.  You agree that any
information  given or  representations  made on the basis of any Sales Materials
shall be consistent with the related information and  representations  contained
in the applicable Fund's Prospectus.

     (c) You  agree to use your  best  efforts  in the  proper  instruction  and

the Prospectus, and all applicable laws, rules and regulations.

     (d) If you  hold  Shares  in  omnibus  accounts,  we will  arrange  for the
delivery of Prospectuses,  periodic reports, proxy materials and other materials
that are  required  by law to be sent to a Fund's  Shareholders  ("Fund  Related
Materials") to the extent such delivery is required by applicable  law, and will
bear  the  cost of such  delivery.  If you  hold  Shares  in  shareholder  level
accounts, you are responsible for the delivery of Fund Related Materials to your
client to the extent such delivery is required by  applicable  law, and you will
bear the cost of such delivery.  We will provide you with the appropriate number
of such  materials  as  requested  by you from time to time.  In the purchase of
Shares through us, you are entitled to rely only on the information contained in
the Fund Related Materials..

     (e) You  agree to  provide  us with  continuous  reasonable  access to your
offices,  representatives  and sales personnel,  at meetings,  in person and via
telephone  or the world  wide web,  and  further  agree to provide us with sales

     (a) You  acknowledge  that  you  have  received  and  reviewed  information
regarding  our  abusive  trading  policy and Funds that charge  redemption  fees
("Redemption  Fee  Funds").  You  represent  and warrant  that you have a policy
designed to prevent  abusive  trading,  (including  market timing) in the mutual
funds you offer,  and that you will  provide us with a copy of such  policy upon
our reasonable request.

     (b) You  covenant  and  agree  that  should  we  identify  abusive  trading
practices  in any of your  accounts,  you will  cooperate  with us in seeking to
eliminate  such abusive  trading  activity.  In  addition,  you agree to provide
detailed transaction activity upon our request.


                                       5



     (c) If at any time you offer  Redemption Fee Funds through accounts trading
at the shareholder  level,  we will track and assess the appropriate  redemption
fee for you. If at any time you offer one or more  Redemption  Fee Funds through
an omnibus  account,  you agree to sign a Redemption Fee Payment  Agreement with
Distributor  which sets forth additional  details with respect to Redemption Fee
Fund availability and payment obligations.

     7. PROCESSING OF TRANSACTIONS.

     (a) If  transactions  in Fund  Shares are to be settled  through the NSCC's
Fund/SERV system, the following provisions shall apply:

          (1) Each  party  to this  Agreement  represents  that it or one of its
     affiliates has entered into the Standard Networking Agreement with the NSCC
     and it desires to participate in the programs offered by the NSCC Fund/SERV
     system which provide (i) an automated process whereby shareholder purchases
     and  redemptions,  exchanges  and  transactions  of mutual  fund shares are
     executed  through  the  Fund/SERV  system,   and  (ii)  a  centralized  and
     standardized  communication  system  for  the  exchange  of  customer-level
     information and account  activity through the Fund/SERV  Networking  system
     ("Networking").

          (2)   For   each   Fund/SERV   transaction,   including   transactions
     establishing  accounts  with us or our  affiliates,  you shall  provide the
     Funds and us with all information necessary or appropriate to establish and
     maintain each Fund/SERV  transaction  (and any  subsequent  changes to such
     information),  which  you  hereby  certify  is and  shall  remain  true and
     correct. You shall maintain documents required by us or the Funds to effect
     Fund/SERV transactions.  Each instruction shall be deemed to be accompanied
     by a representation by you that it has received proper  authorization  from
     each  person  whose  purchase,  redemption,  account  transfer  or exchange
     transaction is effected as a result of such instruction.

          (3) At all times each party shall maintain  insurance coverage that is
     reasonable and customary in light of all its responsibilities hereunder and
     under  applicable law. Such coverage shall insure for losses resulting from
     the  criminal  acts,  errors or omissions  of each  party's  employees  and
     agents.

          (4) The parties agree to  participate  in  Networking  with each other
     under the terms of the Standard Networking  Agreement,  except that (i) the
     section  relating to governing law is hereby amended by deleting the second
     sentence of such section,  and (ii) the section  relating to arbitration of
     disputes is hereby  deleted  and shall be of no force and effect  among the
     parties.

          (5) You  represent  and warrant that all  instructions,  questions and
     other  correspondence  concerning the accounts for which trades are made in


                                       6



     accordance  with this SECTION 7(a) shall come from you, and that individual
     account  holders  shall  contact  you,  rather than contact us or the Funds
     directly,  with instructions,  questions and requests concerning the Funds.
     You further  represent  and warrant that you,  rather than us or the Funds,
     has  reporting   responsibility   to  your  clients  for  confirmations  of
     transactions and monthly, quarterly and year-end statements.

     (b) If  transactions  in Fund  Shares are to be settled  directly  with the
Transfer  Agent,  the  procedures  relating to the  processing and settlement of
Orders shall be subject to such  instructions as we may forward to you from time
to time.  Payment for purchase  transactions  shall be made by wire  transfer or
through a  clearinghouse  agency approved by us to the applicable Fund custodial
account  designated by us on the Business Day next following the Trade Date. Any
such wire transfers shall be instituted by your bank prior to 4:00 p.m.  Eastern
time and  received by the Funds prior to 6:00 p.m.  Eastern time on the Business
Day next  following the Trade Date. If payment for Fund Shares  purchased is not
timely  received,  the Fund may cancel the Order or, at our  option,  resell the
Shares to the  applicable  Fund at the then  prevailing  net asset value and you
shall be  responsible  for all costs to us,  the Funds or any  affiliate  of the
Funds  resulting  from  such  resale.  You  shall be  responsible  for any loss,
expense, liability or damage, including loss of profit suffered by us and/or the
respective Funds resulting from delay or failure to make timely payment for such
Shares or  cancellation of any trade, or for any Orders that are processed on an
"as of" basis as an accommodation to you. You shall not be entitled to any gains
generated thereby.

     (c) You agree not to withhold  placing  Orders  received from any customers
for the purchase or sale of Shares so as to profit  yourself as a result of such
withholding.  You shall not purchase Shares through us except for the purpose of
covering purchase Orders received by you, or for your bona fide investment.  You
agree to purchase Shares only from the Funds or your customers.  If you purchase
Shares  from  your  customers,  you will pay such  customers  not less  than the
applicable  redemption price as established by the relevant Fund's  then-current
Prospectus.

     8. ADDITIONAL COVENANTS.

     (a) Each party shall comply with all  provisions of federal and state laws,
rules  and  regulations  applicable  to its  respective  activities  under  this
Agreement.  All  obligations  of each party under this  Agreement are subject to
compliance with applicable federal and state laws.

     (b) You covenant and agree that all Orders  transmitted  to us,  whether by
telephone, telecopy, or other electronic transmission acceptable to us, shall be
sent by or under the authority  and  direction of a person  designated by you as
being duly  authorized  to act on behalf of the owner of the Shares held in your
accounts. We shall be entitled to rely on the existence of such authority and to
assume  that any person  transmitting  Orders for the  purchase,  redemption  or
transfer  of Fund Shares on your  behalf is "an  appropriate  person" as used in
Sections  8-107 and 8-401 of the  Uniform  Commercial  Code with  respect to the


                                       7



transmission  of  instructions  regarding  Fund Shares on behalf of the owner of
such Fund Shares.  You shall maintain the  confidentiality  of all passwords and
security procedures issued,  installed or otherwise put in place with respect to
the use of remote  computer  terminals  and assume full  responsibility  for the
security  therefor.  You further agree to be responsible for the accuracy of all
data you  transmit  by  telephone,  telecopy  or other  electronic  transmission
acceptable to us.

     (c) You covenant and agree that all Orders  received and transmitted by you
hereunder on any Business Day will be based upon  instructions that you received
from a client in proper  form  prior to the Price Time of the  relevant  Fund on
that Business Day. You shall time stamp all Orders or otherwise maintain records
that will enable you to  demonstrate  compliance  with this SECTION 8(c) hereof.
Further,  upon our  reasonable  request,  you will provide  evidence  reasonably
satisfactory  to the Funds' Board of Directors to  demonstrate  your  compliance
with Rule 22c-1 requirements and provide us with copies of your internal control
report,  if  one is  obtained.  You  agree  to  promptly  return  any  requested
certification  of  such  practices,  and  understand  that  if you do not we may
require you to stop trading through the NSCC (if applicable) and send all trades
directly to us by each Fund's Price Time on any Business Day.

     9.  RELATIONSHIP  OF PARTIES.  You  understand and agree that in performing
your services  covered by this Agreement,  you are acting on your own behalf and
as agent for your customers,  and we are in no way responsible for the manner of
your  performance or for any of your acts or omissions in connection  therewith.
Except to the extent  specifically  set forth herein,  nothing in this Agreement
shall  be  construed  to  constitute  you or any of your  agents,  employees  or
representatives as our agent,  partner, or employee, or the agent or employee of
the  Funds.  Distributor  has full  authority  to take  such  action  as we deem
advisable  in respect  of all  matters  pertaining  to the  distribution  of the
Shares.  Our obligations  under this Agreement are subject to all the provisions
of the distribution  agreements entered into between  Distributor and the Funds.
We shall not be under any obligation to you,  except for  obligations  expressly
assumed by us under this Agreement.

     10. INDEMNITY.

     (a) We  agree  to  indemnify  and  hold  harmless  you and  your  officers,
directors,  employees,  agents, affiliates and each person, if any, who controls
you  within  the  meaning  of the  Securities  Act of  1933  (collectively,  the
"Indemnified  Parties" for purposes of this Section  10(a))  against any losses,
claims,  expenses,  damages or liabilities (including amounts paid in settlement
thereof)  or  litigation   expenses   (including   legal  and  other   expenses)
(collectively,  "Losses"),  to which the Indemnified Parties may become subject,
insofar as such  Losses  result from a breach by us of a material  provision  of
this  Agreement.  We will  reimburse  any  legal  or other  expenses  reasonably
incurred  by  the  Indemnified  Parties  in  connection  with  investigating  or
defending any such Losses. We shall not be liable for indemnification  hereunder
if such Losses are  attributable  to your negligence or misconduct in performing
your obligations under this Agreement.


                                       8



     (b) You agree to indemnify and hold harmless  Distributor,  Transfer  Agent
and the  Funds,  and our  respective  officers,  directors,  employees,  agents,
affiliates  and each  person,  if any,  who  controls us or the Funds within the
meaning of the Securities Act of 1933 (collectively,  the "Indemnified  Parties"
for purposes of this SECTION 10(b)) against any Losses to which the  Indemnified
Parties may become  subject,  insofar as such Losses result from (i) a breach by
you of a material provision of this Agreement,  or (ii) your sales practices and
procedures,  including the provision of any information not provided or approved
by us in accordance  with Section 5 hereof.  You agree to reimburse any legal or
other expenses reasonably incurred by the Indemnified Parties in connection with
investigating  or  defending  any such  Losses.  You  shall  not be  liable  for
indemnification  hereunder if such Losses are  attributable to our negligence or
misconduct in performing our obligations under this Agreement.

     (c) Promptly after receipt by an indemnified  party  hereunder of notice of
the commencement of action,  such indemnified  party will, if a claim in respect
thereof is to be made  against  the  indemnifying  party  hereunder,  notify the
indemnifying  party of the commencement  thereof;  but the omission so to notify
the indemnifying  party will not relieve it from any liability which it may have
to any indemnified  party otherwise than under this SECTION 10. In case any such
action  is  brought  against  any  indemnified   party,   and  it  notifies  the
indemnifying party of the commencement  thereof,  the indemnifying party will be
entitled to  participate  therein and, to the extent that it may wish to, assume
the defense thereof,  with counsel  satisfactory to such indemnified  party, and
after  notice  from  the  indemnifying  party to such  indemnified  party of its
election  to assume the  defense  thereof,  the  indemnifying  party will not be
liable to such  indemnified  party under this  Section 10 for any legal or other
expenses  subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     (d) If the indemnifying  party assumes the defense of any such action,  the
indemnifying  party  shall  not,  without  the  prior  written  consent  of  the
indemnified  parties in such action,  settle or compromise  the liability of the
indemnified  parties in such action, or permit a default or consent to the entry
of any judgment in respect  thereof,  unless in connection with such settlement,
compromise or consent,  each  indemnified  party  receives from such claimant an
unconditional release from all liability in respect of such claim.

     11.  AMENDMENT.  This  Agreement may be amended by mutual  agreement of the
parties in writing.

     12.  TERMINATION.  Any party may cancel this  Agreement upon 30 days' prior
written  notice to the  other.  This  Agreement  shall  terminate  automatically

cease to be a member of the NASD,  breach any  provision  of Section 2830 of the
NASD Conduct Rules, or you cease to be a bank, as defined above, or (c) upon any
attempted  assignment hereof. This Agreement may be terminated at any time as to
any Fund by a vote by a majority  of the  independent  directors  or trustees of
that Fund.  We reserve  the right,  in our sole  discretion  and  without  prior


                                       9



notice,  to  suspend  sales  of  Shares  of the  Funds  in any  state  or  other
jurisdiction, or to withdraw entirely the offering of Shares of the Funds, or to

applicable  privacy laws.  Each of the parties  agrees not to use, or permit the
use of, any such customer  information  for any purpose  except to carry out the
terms of this  Agreement  and/or  pursuant to any  exceptions  set forth in such
privacy laws. This provision shall survive the termination of this Agreement.

all applicable laws and regulations aimed at preventing, detecting and reporting
money laundering and suspicious  transactions,  including,  without  limitation,
