IMPORTANT NEWS FOR SHAREHOLDERS
 
While we encourage you to read all of the enclosed Proxy Statement/Prospectus, here is a brief overview of the proposals you will be asked to vote on.

Questions and Answers
 
Q.
What are the proposals to be voted on at the special meeting of shareholders?
 
A .
Shareholders of the American Century Life Sciences Fund and the American Century Technology Fund are being asked to approve the reorganization of each fund into the American Century Growth Fund (referred to as the reorganizations). If approved, this would result in the tax-free reorganization of those funds into Growth .
 
Q .
When will the special meeting be held? Who can vote?
 
A .
The special meeting will be held on Tuesday,   May 5, 2009, at 10:00 a.m. Central Time at American Century’s office at 4500 Main Street , Kansas City , Missouri . T his will be a business meeting only , as n o presentations about the funds are planned. If you owned shares of  either Life Sciences or Technology at the close of business on February 20, 2009, you are entitled to vote, even if you later sold the shares. Each shareholder is entitled to one vote per dollar of shares owned, with fractional dollars voting proportionally.
 
Q .
What are the reorganizations?
 
A .
The following table outlines the proposed reorganizations and shows what Life Sciences and Technology shareholders will receive if the reorganizations are approved:
 
 
If you own shares of:
 
You will receive shares of:
Life Sciences
     Investor Class
     Institutional Class
 
Growth
    Investor Class
    Institutional Class

Q .
How will the reorganizations affect my investments in the funds?
 
A.
If approved, you will receive shares of Growth in exchange for your shares of Life Sciences and Technology. The reorganizations:
 
 
WILL NOT BE TAXABLE (See “INFORMATION ABOUT THE REORGANIZATIONS – Federal Income Tax Consequences of the Reorganizations”);
 
 
WILL RESULT IN SHAREHOLDERS PAYING LOWER FUND EXPENSES (The total operating expenses for the shares of Growth to be received in the reorganizations are lower than those for the shares of Life Sciences and Technology ); and
 
 
WILL BROADEN YOUR FUND’S INVESTMENT UNIVERSE (Growth may not concentrate its investments in a particular industry, whereas Life Sciences may concentrate in the medical and health care industries and Technology may concentrate investments in the technology or telecommunications industries . Additionally, Growth is classified as diversified, whereas Life Sciences and Technology are classified as nondiversified. A nondiversified fund may invest in a smaller number of securities than a diversified fund ).

Q.
How will the reorganizations work?
 
A.
The reorganizations will involve the following:
 
 
• the transfer of the net assets of each of Life Sciences and Technology to Growth in exchange for shares of Growth having equivalent value to the net assets transferred;
 
 
• the pro rata distribution of shares of Growth to the shareholders of record of Life Sciences and Technology in exchange for their shares in Life Sciences and Technology; and
 
 
• the termination of Life Sciences and Technology following the reorganizations.
 
 
The reorganizations would take place on the Closing Date, as defined in the Proxy Statement/Prospectus.
 
Q.
Will I have to pay any sales charges on shares received in the reorganizations?
 
A.
No. The Investor Class and Institutional Class shares to be received in the reorganizations do not carry a front-end sales charge (load) or contingent deferred sales charge.
 
Q .
How does the Board of Directors of Life Sciences and Technology recommend that I vote?
 
A .
The Board of Directors, including all of the Independent Directors, unanimously recommend s you vote FOR the reorganizations. For a discussion of the factors the Board considered in approving the reorganizations, see “Reasons for the Reorganizations” under the heading “Information About the Reorganizations.”
 
Q.
My holdings in the funds are small, why should I vote?
 
A .
Your vote makes a difference. If many shareholders do not vote their proxies, your fund may not receive enough votes to go forward with its special meeting. This means additional costs will be incurred to solicit votes to determine the outcome of the proposals.
 
Q.
 What happens if either of the reorganizations is not approved by shareholders?
 
A .
Each reorganization is a separate transaction, and is not dependent upon the approval of the other reorganization. If a reorganization does not receive shareholder approval, American Century may ask for Board approval to liquidate the affected fund .
 
Q.
How do I cast my vote?
 
A .
You may vote:

SUMMARY
 
This summary is qualified in its entirety by the additional information contained elsewhere in this Proxy Statement/Prospectus, or incorporated by reference into this Proxy Statement/Prospectus. A form of the Agreements and Plans of Reorganization pursuant to which the Reorganizations will be conducted is attached to this Proxy Statement/Prospectus as Exhibit A. For additional information, please read the Growth prospectus, which accompanies this Proxy Statement/Prospectus.
 
 
Introduction
 
This Proxy Statement/Prospectus is furnished to you because you are entitled to vote on one or more of the proposals described in this Proxy Statement/Prospectus that will be considered at the Meeting. The Meeting will be held on May 5, 2009 .
 
The following is a brief summary of the proposals that will be voted on at the Meeting:
 
1.
It is being proposed that Growth acquire the net assets of Life Sciences, in exchange for Investor Class and Institutional Class shares of Growth (the “Life Sciences/Growth Exchange”). Immediately following the Life Sciences/Growth Exchange, Life Sciences will distribute the Investor Class and Institutional Class shares of Growth to holders of the Investor Class and Institutional Class shares of Life Sciences, respectively (the “Life Sciences Fund Distribution”). The Life Sciences/Growth Exchange and the Life Sciences Fund Distribution are collectively referred to in this Proxy Statement/Prospectus as the “Life Sciences Fund Reorganization.” If approved, as a result of the Life Sciences Fund Reorganization, each holder of Investor Class and Institutional Class shares of Life Sciences will receive the same percentage of the aggregate number of Investor Class and Institutional Class shares of Growth issued in the Life Sciences Fund Reorganization as he or she owned in Life Sciences, having a total net asset value (“NAV”) equal to the total NAV of his or her Life Sciences holdings on the Closing Date (as hereafter defined).
 
2.
It is being proposed that Growth acquire the net assets of Technology, in exchange for Investor Class and Institutional Class shares of Growth (the “Technology/Growth Exchange”). Immediately following the Technology/Growth Exchange, Technology will distribute the Investor Class and Institutional Class shares of Growth to holders of the Investor Class and Institutional Class shares of Technology, respectively (the “Technology Fund Distribution”). The Technology/Growth Exchange and the Technology Fund Distribution are collectively referred to in this Proxy Statement/Prospectus as the “Technology Fund Reorganization.” If approved, as a result of the Technology Fund Reorganization, each holder of Investor Class and Institutional Class shares of Technology will receive the same percentage of the aggregate number of Investor Class and Institutional Class shares of Growth issued in the Technology Fund Reorganization as he or she owned in Technology, having a total NAV equal to the total NAV of his or her Technology holdings on the Closing Date (as hereafter defined).
 
The Board of Directors of the aforementioned Funds shall be collectively referred to as the “Boards.” The Boards, including Directors who are not “interested persons” within the meaning of Section 2(a)(19) of the Investment Company Act of 1940, as amended (“1940 Act”), have concluded that the Reorganizations are in the best interests of shareholders of Life Sciences, Technology and Growth.
 
Consummation of either Reorganization is not conditioned upon the consummation of the other Reorganization. If a Reorganization does not receive shareholder approval, American Century may ask the Board of Directors of American Century World Mutual Funds, Inc. (“ACWMF Board ”)   for approval to liquidate the affected Fund.
 
Each Reorganization will be a tax-free event under applicable provisions of the Internal Revenue Code, as amended, so that no gain or loss will be recognized by the Funds or Life Sciences’ or Technology’s shareholders. As a condition to its Reorganization, each Fund will receive an opinion of Reed Smith, LLP that the Reorganization will be considered a tax-free “reorganization” under applicable provisions of the Internal Revenue Code of 1986, as amended, so that no gain or loss will be recognized by either Life Sciences or Technology ( or their respective shareholders ) or Growth . The tax basis of the shares of Growth received by Life Sciences and Technology shareholders will be the same as the tax basis of their shares in Life Sciences and Technology.
 
 
Closing Dates
 
If all of the requisite approvals are obtained and certain conditions are either met or waived, it is anticipated that the Reorganizations will be consummated following the close of business on May 29, 2009 or on such other date as American Century may decide (the “Closing Date”) and that shareholders of Life Sciences and Technology will receive shares of Growth by the next business day following the Closing Date.
 
 
Reasons for the Proposed Reorganizations
 
The advisor to Life Sciences, American Century Global Investment Management, Inc. (“ACGIM”) , and the advisor to Technology, American Century Investment Management, Inc. (“ACIM”) (ACGIM and ACIM, collectively referred to as “American Century” or the “Advisor”) , have recommended the proposed R eorganizations to the ACWMF Board because they believe that the Reorganizations will result in a more viable investment for shareholders of both Life Sciences and Technology (collectively, the “Acquired Funds”) . In

making its recommendation , the Advisor has indicated that, despite efforts to increase sales, the Acquired Funds have not grown to a viable size.  In addition, the Advisor noted that, as shown below in the “Comparative Fee Tables,” shareholders of the Acquired Funds are expected to benefit from a reduction in expenses as a result of the Reorganizations.
 
In considering the Advisor’s recommendation with respect to the proposed Reorganizations, the ACWMF Board took into consideration a number of factors, including: (1) the viability of each of the Acquired Funds absent approval of the proposed Reorganizations and the greater long-term viability of Growth; (2) the relative compatibility of the investment objectives and policies of each of the Acquired Funds with Growth; (3) the comparative investment performance of Life Sciences to Growth , and Technology to Growth; (4) the fact that the Reorganizations are expected to be “tax-free” for federal income tax purposes (and that the Funds will receive an opinion of counsel to this effect); (5) that the proposed Reorganizations are expected to result in lower fees, as a percentage of net assets, for shareholders of both Life Sciences and Technology; and (6) the undertaking by American Century to pay all costs and expenses of preparing, printing and mailing this Proxy Statement/Prospectus and solicitation expenses of the Reorganizations.
 
For a more detailed discussion of the factors considered by the ACWMF Board in approving the Reorganizations, see “Reasons for the Proposed Reorganizations.”
 
 
Comparison of Investment Objectives, Policies and Risks
 
Investment Objectives
 
The investment objectives of Life Sciences, Technology and Growth are substantially similar.  Life Sciences and Technology seek capital growth, whereas Growth seeks long-term capital growth.
 
 
Investment Exposure
 
The portfolio managers for Growth look for stocks of larger-sized companies.  Although the portfolio managers intend to invest the fund’s assets primarily in U.S. stocks, the fund may invest in securities of foreign companies, including companies located in emerging markets.  Life Sciences and Technology may invest in U.S. and foreign companies of any size.
 
To achieve its objective, Life Sciences invests at least 80% of its assets in companies that engage in the business of providing products and services that help promote health and wellness. Life science companies generally own, operate or support healthcare facilities (including, among others, hospitals, outpatient surgery facilities, dialysis centers, dental centers and physical therapy centers); design, manufacture or sell pharmaceuticals, biopharmaceuticals, medical research facilities, and medical devices and supplies; or provide biotechnology needed to improve agriculture, aquaculture, forestry, chemicals, household products and cosmetics/personal care products, environmental cleanup, food processing, and forensic medicine.
 
To achieve its objective, Technology invests at least 80% of its assets in companies that the portfolio managers believe are principally engaged in offering, using or developing products, processes or services that provide or will benefit significantly from technological advancements or improvements. The portfolio managers consider technology and telecommunications-related industries to include among others, computers (including software, products and electronic components), semiconductors, networking, internet and on-line service providers, office automation, telecommunications, communications equipment, information technology and commercial services, media and information services, electronics, electrical equipment, electronic equipment, and defense and aerospace.
 
The Fund's portfolio managers do not attempt to time the market. Instead, under normal market conditions, they intend to keep the Funds essentially fully invested in stocks regardless of the movement of stock prices generally.  When the managers believe it is prudent, Growth may invest a portion of its assets in debt securities, options, preferred stock and equity-equivalent securities.  Life Sciences and Technology may purchase preferred stock, equity-equivalent securities, forward currency exchange contracts, notes, bonds and other debt securities of companies, and obligations of domestic or foreign governments and their agencies.  The Life Sciences and Technology managers also may purchase put options (i.e., the right to sell a security at a specified price by a certain date) for some securities that the fund holds in order to hedge against adverse price fluctuations of those securities. The managers may purchase put options to cover up to 10% of Life Sciences or Technology assets.
 
Futures contracts, a type of derivative security, can help the Funds’ cash assets remain liquid while performing more like stocks. The Funds have a policy governing futures and similar derivative securities to help manage the risk of these types of investments.
 
 
Stock Selection Process
 
The Funds' portfolio managers look for stocks of companies they believe will increase in value over time, using a bottom-up approach to stock selection. This means that the managers make their investment decisions based primarily on their analysis of individual companies, rather than on broad economic forecasts.  T he  portfolio managers track financial information for thousands of individual companies to identify and evaluate trends in earnings, revenues and other business fundamentals.  Management of Growth is based on the belief that, over the long term, stock price movements follow growth in earnings, reve nues and/or cash flow. Management of Life Sciences and Technology is based on the belief that, over the long term, stock price movements follow growth in earnings and revenues.
 
8

 
Under normal market conditions, Growth’ s portfolio will primarily consist of securities of companies demonstrating business improvement. Analytical indicators helping to identify signs of business improvement could include accelerating earnings or revenue growth rates, increasing cash flows, or other indications of the relative strength of a company’s business.  These techniques help the portfolio managers buy or hold the stocks of companies they believe have favorable growth prospects and sell the stocks of companies whose characteristics no longer meet their criteria.
 
The Life Sciences and Technology portfolio managers’ principal analytical technique involves the identification of companies with earnings and revenues that are not only growing, but growing at an accelerating pace. This includes companies whose growth rates, although still negative, are less negative than prior periods, and companies whose growth rates are expected to accelerate. In addition to locating strong companies with earnings and revenue growth, the portfolio managers invest in companies that experience a change in their business that may stimulate future revenue and earnings acceleration and lead to positive investor perception. The change typically is the result of key events including: entry into a new market, development of a new product, obtaining a new patent or license, or, for Life Sciences, the presentation of clinical data showing efficacy for a new drug or medical device. The portfolio managers for Life Sciences and Technology also believe that it is important to diversify the F und s ’ holdings across geographical regions and different countries. For this reason, the portfolio managers also consider the prospects for relative economic growth among countries or regions, economic and political conditions, expected inflation rates, currency exchange fluctuations, and tax considerations when making investments.
 
 
Investment Limitations
 
Each Fund has fundamental investment limitations, which may not be changed with out shareholder approval.  With the exception of the Funds’ respective polic ies regarding concentration of investments and diversification , the fundamental limitations of the Funds are identical.
 
With respect to the concentration polic y, Growth 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).  However, Technology may concentrate its investments in securities of issuers engaged in the technology or telecommunications industries and related industry groups and Life Sciences may concentrate its investments in securities of issuers or engaged in the medical and health care industry and related industry groups.
 
Growth is diversified as defined in the 1940 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). Life Sciences and Technology are nondiversified. Nondiversified means that a fund may invest a greater portion of its assets in a smaller number of securities than a diversified fund. Although Life Sciences’ and Technology’s portfolio managers expect that the Funds will ordinarily satisfy the requirements of a diversified fund, their nondiversified status gives each Fund more flexibility to invest heavily in the most attractive companies identified by its methodology.
 
A complete list of each fund’s investment limitations is attached as Exhibit D to this Proxy Statement/Prospectus.
 
 
Comparison of Principal Risks
 
Because the Funds have similar investment objectives and strategies, many of the risks associated with investing in the Funds are similar.  The following summarizes and compares the principal risks of investing in the Funds, as disclosed in each Fund’s prospectus.  The fact that a risk is not listed as a principal risk in a Fund’s prospectus does not necessarily mean that shareholder s of that Fund are not subject to that risk.
 
Life Sciences, Technology and Growth are each subject to the following principal risks:
 
Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and growth stock prices tend to fluctuate more dramatically than the overall stock market.
 
The portfolio managers may buy a large amount of a company’s stock quickly, and often will dispose of it quickly if the company’s earnings or revenues decline. While the portfolio managers believe this strategy provides substantial appreciation potential over the long term, in the short term it can create a significant amount of share price volatility. This volatility can be greater than that of the average stock fund.
 
Each Fund may invest in securities of foreign companies. Foreign investment involves additional risks, including fluctuations in currency exchange rates, less stable political and economic structures, reduced availability of public information, and lack of uniform financial reporting and regulatory practices similar to those that apply in the United States . These factors make investing in foreign securities generally riskier than investing in U.S. stocks. To the extent the F unds invest in foreign securi ties, the overall risk of that F und could be affected.

Market performance tends to be cyclical, and, in the various cycles, certain investment styles may fall in and out of favor. If the market is not favoring the F und’s style, the fund’s gains may not be as big as, or its losses may be bigger than, other equity funds using different investment styles
 
The value of each F und’s shares depends on the value of the stocks and other securities it owns. The value of the individual securities the fund owns will go up and down depending on the performance of the companies that issued them, general market and economic conditions, and investor confidence.
 
 
At any given time your shares may be worth less than the price you paid for them. In other words, it is possible to lose money by investing in the F und.
 
 
Life Sciences and Technology also are subject to the following principal risks. Although Growth may be subject to these risks as well, they are not considered to be principal risks of Growth.
 
Life Sciences focuses its investments among companies in the life sciences sector and Technology focuses its investments among companies in the technology and telecommunications-related sector. Because those investments are concentrated in a comparatively narrow segment of the total market, the funds’ investments are not as diversified as those of many other mutual funds. Because of this, companies in each F und’s portfolio may react similarly to market developments, such as government regulation, subsidies or technological advancements. This means that each F und’s net asset value may be more volatile than that of less concentrated funds. As a result, the value of an investment in the F und s may rise or fall rapidly.
 
Life Sciences and Technology are nondiversified. This means that the portfolio managers 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 each   F und’s share price than would be the case if the F und s were diversified. Although the portfolio managers expect each Fund will ordinarily invest in enough securities to qualify as a diversified fund, its nondiversified status gives it more flexibility to invest heavily in the most attractive companies identified by the F und’s methodology.
 
Life Sciences and Technology’s portfolio turnover may be high. This could result in relatively high commission costs, which could hurt the funds’ performance and increase capital gains tax liabilities for the F unds’ shareholders.
 
Many faster-growing life sciences, technology and telecommunications-related companies have limited operating histories.  For Life Sciences companies in particular, their potential profitability may be dependent on regulatory approval of their products and many of these companies’ activities are funded or subsidized by government grants or other funding, which may be reduced or withdrawn. Changes in government regulation also can have an impact on a company’s profitability and/or stock price. Continuing technological advances may mean rapid obsolescence of key products and services. These business uncertainties may increase the volatility of the prices for these companies’ securities.
 
I nvesting in securities of companies located in emerging market countries generally is also riskier than investing in securities of companies located in foreign developed countries. Emerging market countries may have unstable governments and/or economies that are subject to sudden change. These changes may be magnified by the countries’ emergent financial markets, resulting in significant volatility to investments in these countries. These countries also may lack the legal, business and social framework to support securities markets.
 
Life Sciences and Technology may invest in companies regardless of size, which means they may invest in smaller U.S. and foreign companies. Investing in securities of smaller companies generally presents unique risks. Smaller companies may have more limited resources, trade less frequently and have less publicly available information. They also may be more sensitive to changing political and economic conditions. These factors may cause investments in smaller companies to experience more price volatility.
 
In addition to publicly traded securities, Life Sciences and Technology each may invest up to 15% of its assets in privately placed securities. These securities may be considered illiquid if they cannot be sold in seven days at approximately the price at which the fund is valuing them. Privately placed securities are valued by the manager pursuant to procedures established by the F und’s Board of Directors.
 
Life Sciences and Technology’s performance also may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund’s performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund’s performance as its assets grow.
 
Option prices can be volatile, and trading in options will expose a   F und to certain risks. For instance, if the price of the option’s underlying security does not change in the anticipated direction to an extent sufficient to cover the cost of the option before the option expires, the F und may lose all or a significant part of its investment in the option.

Each fund pays the A dvisor a single, unified management fee for arranging all services necessary for the F und to operate. The fee shown is based on assets during each F und’s most recent fiscal year. Each F und has a stepped f ee schedule. As a result, each F und’s unified management fee rate generally decreases as strategy assets increase and increases as strategy assets decrease. For more information about the unified management fee, including an explanation of strategy assets, see The Investment Advisor under Management in the Funds’ prospectuses .

Life Sciences and Technology Average Annual Total Returns
 
The following table shows the average annual total returns of the Acquired Funds’ Investor Class shares calculated three different ways. An additional table shows the average annual total returns of the Funds’ Institutional C lass shares calculated before the impact of taxes. Returns assume the deduction of all charges and other fees associated with a particular class. Your actual returns may vary depending on the circumstances of your investment.
 
Return Before Taxes shows the actual change in the value of Fund shares over the time periods shown, but does not reflect the impact of taxes on Fund distributions or the sale of Fund shares. The two after-tax returns take into account taxes that may be associated with owning Fund shares. Return After Taxes on Distributions is a Fund’s actual performance, adjusted by the effect of taxes on distributions made by the Fund during the periods shown. Return After Taxes on Distributions and Sale of Fund Shares is further adjusted to reflect the tax impact on any change in the value of Fund shares as if they had been sold on the last day of the period.
 
After-tax returns are calculated using the historical highest federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or IRAs.
 
The benchmarks are unmanaged indices that have no operating costs and are included in the table for performance comparison. The S&P 500 ® Index is a market value-weighted index of the stocks of 500 publicly traded U.S. companies chosen for market size, liquidity, and industry group representation that are considered to be leading firms in dominant industries. The S&P Composite 1500 Hea lth Care Index represents companies in the S&P Composite 1500 (which combines the S&P 500, MidCap 400 and Smallcap 600 indices ) in two main industry groups: Health care equipment and supplies companies or companies that provide health care related services, and companies that provide research, development, production and marketing of pharmaceuticals and biotechnology products. The S&P 1500 Technology Index represents those S&P Composite1500 companies in two main industries groups: technology software and services companies, and technology hardware and equipment companies.

The Investment Advisors
 
American Centur y Investment Management, Inc. (“ ACIM ”) serves as investment advisor to Technology and Growth , and American Century Global Inve stment Management, Inc. (“ACGIM” ) serves as investment advisor to Life Sciences. ACIM has been managing mutual funds since 1958 and is headquartered at 4500 Main Street , Kansas City , Missouri   64111 . ACGIM, a wholly owned subsidiary of ACIM, has been managing mutual funds since 2006 and is headquartered at 666 3 rd Avenue, 23 rd Floor, New York, New York 10017.
 
ACIM and ACGIM (each an “Advisor and collectively the “Advisors”) are responsible for managing the investment portfolio s of the Funds and directing the purchase and sale of their investment securities. The Advisors also arrange for transfer agency, custody and all other services necessary for each Fund to operate.
 
For the services it provides to each F und, the A dvisor receives a unified management fee based on a percentage of the daily net assets of each class of shares of the F und. The amount of the fee is calculated daily and paid monthly in arrears. Out of that fee, the A dvisor pays all expenses of managing and operating the fund except brokerage expenses, taxes, interest, fees and expenses of the independent directors (including legal counsel fees), and extraordinary expenses. A portion of the fund’s man agement fee may be paid by the F und’s A dvisor to unaffiliated third parties who provide recordkeeping and administrative services that would otherwise be performed by an affiliate of the A dvisor.
 
The rate of the fee is determined by applying a formula that takes into account the assets of each F und as well as certain assets, if any, of other clients of the A dvisor outside the American Century Investments fund family (such as subadvised funds and separate accounts) that use very similar in vestment teams and strategies (“ strategy assets ). Growth ’s strategy assets also include the assets of the NT Growth Fund. The use o f strategy assets, rather than F und assets, in calculating the F und’s fee rate could allow the F und to realize scheduled cost savings more quickly. Ho wever, it is possible that the F und’s strategy assets will not include assets of other client accounts or that any such assets may not be sufficient to result in a lower fee rate.

INFORMATION ABOUT THE REORGANIZATIONS
 
Terms of the Agreements and Plans of Reorganization
 
Set forth below is a summary of certain material terms of the Agreements and Plans of Reorganization (“Plans”). This summary is qualified in its entirety by the terms and provisions of the form of Plan which is attached to this Proxy Statement/Prospectus as Exhibit A.
 
The Plans provide that all of the assets of Life Sciences and Technology will be transferred to Growth at 4:00 p.m., Eastern Time, on the Closing Date of the Reorganizations (which is expected to be on or about May 29, 2009 ).
 
In exchange for the transfer of these assets, Growth will simultaneously issue a number of full and fractional shares to each of Life Sciences and Technology equal in value to the aggregate net assets of the respective Funds calculated at the time of the Reorganizations. The Plans contemplate that each of the Acquired Funds will discharge all of its liabilities and obliga tions prior to the Closing Date. Growth shall not assume or agree to pay, satisfy, discharge or perform any liabilities (contingent or otherwise) of the Acquired Funds.
 
When calculating the value of the assets of Life Sciences and Technology for purposes of each Reorganization, the net asset values will be determined in accordance with Growth's valuation procedures. However, since the valuation procedures used by Growth are identical in most respects to those used by Life Sciences and Technology, there are not anticipated to be differences in the valuation methods used to value the securities held by Life Sciences and Technology at the time of the Reorganizations.
 
Following the transfer of assets in exchange for shares of Growth, Life Sciences and Technology will distribute all of the shares of Growth pro rata to their shareholders of record in complete liquidation of Life Sciences and Technology. Shareholders of Life Sciences and Technology owning shares at the time of the Reorganization will receive the same percentage of the aggregate number of corresponding Growth shares issued as such shareholder owned in Life Sciences and Technology at the time of the Reorganizations. Such distribution will be accomplished by the establishment of accounts in the names of each Life Sciences and Technology shareholder on the share records of Growth's transfer agent. Each account will receive the respective pro rata number of full and fractional Growth shares due to the shareholder of Life Sciences and Technology. Life Sciences and Technology will then be terminated. Growth does not issue share certificates to shareholders. Growth shares to be issued will have no preemptive or conversion rights. No sales charge will be imposed in connection with the receipt of such shares by the shareholders of Life Sciences and Technology.
 
In connection with the Reorganizations, holders of Investor Class shares of Life Sciences and Technology will receive Investor Class shares of Growth and holders of Institutional Class shares of Life Sciences and Technology will receive Institutional Class shares of Growth. Shares of Growth to be issued to shareholders of Life Sciences and Technology under the Plans will be fully paid and non-assessable when issued, transferable without restriction and will have no subscription rights. Reference is hereby made to the prospectus of Growth provided herewith for additional information about shares of Growth.
 
The Plans contain customary representations, warranties and conditions. Each Plan provides that the consummation of the Reorganizations with respect to Life Sciences and Technology and Growth are conditioned upon, among other things: (i) approval of the Reorganizations by the shareholders of Life Sciences and Technology, respectively; and (ii) the receipt by Life Sciences, Technology and Growth of a tax opinion to the effect that the Reorganizations will be tax-free to Life Sciences and Technology (and their respective shareholders) and Growth. Any Plan may be terminated if, before the Closing Date, any of the required conditions have not been met, the representations and warranties are not true (and have not been cured within 30 days), or the ACWMF Board or the Board of Directors of American Century Mutual Funds, Inc. (“ACMF Board”) determine that a Reorganization is not in the best interest of the shareholders of Life Sciences, Technology or Growth, respectively. The Reorganizations are not anticipated to result in dilution of the net asset value of Life Sciences, Technology or Growth immediately following their consummation. Consummation of one of the Reorganizations is not a condition to the closing of the other Reorganization.
 
 
Costs of the Reorganizations
 
The expenses of each Reorganization will be paid by American Century. Reorganization expenses include: (a) expenses associated with the preparation and filing of this Proxy Statement/Prospectus; (b) postage; (c) printing; (d) accounting fees; (e) legal fees incurred in the preparation of the Proxy Statement/Prospectus; (f) solicitation costs; and (g) other related administrative or operational costs. Any registration or licensing fee will be borne by the Fund incurring such fee. Life Sciences and Technology will pay for any brokerage charges associated with the disposition of their respective portfolio securities prior to the Reorganizations. Growth will pay for brokerage charges and other transaction costs associated with transactions (whether purchase or sale)   involving assets received from Technology and Life Sciences in the Reorganizations.

Reasons for the Reorganizations
 
In determining to approve the Reorganizations and to recommend approval of the Reorganizations to shareholders of Life Sciences and Technology, the ACWMF Board made inquiries into all matters deemed relevant and considered the following, among other items:
 
The viability of both Life Sciences and Technology absent approval of the proposed Reorganizations;
 
The relative compatibility of the investment objectives and principal investment policies of Growth and Life Sciences , and Growth and Technology;
 
The comparative investment performance of Life Sciences and Growth, and Technology and Growth;
 
The comparative management and other fees paid by the Funds;
 
The federal income tax treatment of the Reorganizations; and
 
The undertaking by American Century to pay the above-referenced expenses associated with the Reorganizations.
 
Some of these factors are discussed in greater detail below.
 
The ACWMF Board considered that neither Life Sciences nor Technology has grown substantially since their launch in 2000 despite efforts to increase sales of the se Funds. Life Sciences and Technology also show limited potential for future growth, as the demand for sector funds has decreased and the overall market for health care and technology-related funds has shrunk with exchange traded funds taking market share from actively managed funds. Accordingly, the ACWMF Board concluded that neither Life Sciences nor Technology w as likely to reach a viable asset size.
 
As discussed in the section entitled “SUMMARY-Comparison of Investment Objectives and Policies,” the investment objectives of each of Life Sciences and Technology are substantially similar to that of Growth.  Growth also uses a growth investment methodology that places it near Life Sciences and Technology in Morningstar ’s comparison of growth stocks .
 
The ACWMF Board also considered that the Acquired Funds will receive a tax opinion of Reed Smith, LLP that each Reorganization will be considered a tax-free reorganization under applicable provisions of the Internal Revenue Code of 1986, as amended, so that no gain or loss will be recognized by Life Sciences or Technology (or their respective shareholders) , or Growth. Prior to the Reorganizations, if a Life Sciences or Technology shareholder were to redeem its investment in Life Sciences or Technology and invest the proceeds in another fund or other investment product, such shareholder generally would recognize gain or loss for federal income tax purposes upon the redemption of the shares. By contrast, it is intended that, as a result of the Reorganizations: (i) shareholders of the Acquired Funds will not recognize a taxable gain or loss on the exchange of their Life Sciences or Technology shares for shares of Growth; (ii)   shareholders of the Acquired Funds will have the same aggregate tax cost basis in Growth shares received in connection with the Reorganizations as in their Life Sciences or Technology shares; and (iii) assuming that Life Sciences and Technology shares are held as a capital asset on the Closing Date, the holding period for Growth shares will include the period for which such shareholder held its Life Sciences or Technology shares.
 
American Century, or one or more of its affiliates, will bear certain costs associated with the Reorganizations, including proxy solicitation and tabulation costs. See “Costs of the Reorganizations” under “Information About the Reorganizations” for further information.
 
 
Recommendation in Favor of Approval of the Reorganizations
 
Based on the foregoing, together with other factors and information considered to be relevant, and recognizing that there can be no assurance that any benefits will in fact be realized, the ACWMF Board concluded that each Reorganization is in the best interests of all affected shareholders.
 
Pursuant to Rule 17a-8 under the 1940 Act, the ACWMF Board, including all of the Directors who are not “interested persons” within the meaning of Section 2(a)(19) of the 1940 Act (“Independent Directors”), determined that each Reorganization is in the best interests of Life Sciences and Technology, respectively, and their respective shareholders. In addition, the ACWMF Board, including all of the Independent Directors, also determined that the interests of the shareholders of Life Sciences and Technology would not be diluted as a result of effecting each respective Reorganization because each such shareholder will receive corresponding shares of Growth having an aggregate net asset value equal to the aggregate net asset value of his or her shares in Life Sciences and Technology, respectively, outstanding as determined at the Closing Date . Consequently, the ACWMF Board approved the Reorganizations and directed that they be submitted to the shareholders of each of Life Sciences and Technology, respectively , for approval.
 
The ACMF Board likewise approved the Reorganizations on behalf of Growth. Pursuant to Rule 17a-8 under the 1940 Act, the ACMF Board, including a majority of the Independent Directors, determined that participation in the Reorganizations was in the best interests of Growth’s shareholders and that the interests of existing Growth shareholders would not be diluted as a result of effecting the Reorganizations. Approval of the shareholders of Growth is not required to effect the Reorganizations.

THE AMERICAN CENTURY WORLD MUTUAL FUNDS, INC. BOARD UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS OF LIFE SCIENCES AND TECHNOLOGY APPROVE THE CORRESPONDING PLANS OF REORGANIZATION. CONSUMMATION OF THE REORGANIZATIONS WITH RESPECT TO ONE FUND IS NOT CONTINGENT UPON THE APPROVAL OF THE PLAN OF REORGANIZATION BY SHAREHOLDERS OF THE OTHER FUND.
 
 
Federal Income Tax Consequences of the Reorganizations
 
 
As a condition to each Reorganization, Life Sciences, Technology and Growth will receive opinions of counsel to the effect that, on the basis of the existing provisions of the Code, current administrative rules and court decisions, for federal income tax purposes:
 
the Reorganizations as set forth in the Plans will each constitute a tax-free reorganization under section 368(a) of the Code, and the parties to the Plans each will be a “party to a reorganization” within the meaning of section 368(b) of the Code;
 
no gain or loss will be recognized by Growth upon its receipt of the assets of Life Sciences or Technology in exchange for Investor Class and Institutional Class shares of Growth;
 
no gain or loss will be recognized by Life Sciences upon transfer of its assets to Growth in exchange for Investor Class and Institutional Class shares of Growth or upon the distribution of Investor Class and Institutional Class shares of Growth to Life Sciences’ shareholders in exchange for their shares of Life Sciences;
 
no gain or loss will be recognized by Technology upon transfer of its assets to Growth in exchange for Investor Class and Institutional Class shares of Growth or upon the distribution of Investor Class and Institutional Class shares of Growth to Technology’s shareholders in exchange for their shares of Technology;
 
no gain or loss will be recognized by shareholders of Life Sciences or Technology upon exchange of their shares for Investor Class and Institutional Class shares of Growth;
 
the aggregate tax basis of Investor Class and Institutional Class shares of Growth received by each shareholder of Life Sciences and Technology, respectively, pursuant to the Reorganizations will be the same as the aggregate tax basis of the shares of Life Sciences and Technology, respectively, held by such shareholder immediately prior to the Reorganizations;
 
the holding period of the Investor Class and Institutional Class shares of Growth received by each shareholder of Life Sciences and Technology pursuant to the Plans will include the period during which shares of Life Sciences and Technology exchanged therefore were held by such shareholder, provided the shares of Life Sciences and Technology were held as capital assets on the date of the Reorganizations;
 
the tax basis of the assets of Life Sciences and Technology acquired by Growth will be the same as the tax basis of such assets to Life Sciences and Technology immediately prior to the Reorganizations; and
 
the holding period of Life Sciences and Technology’s assets in the hands of the Growth will include the period during which those assets were held by Life Sciences and Technology.
 
The foregoing opinion may state that no opinion is expressed as to the effect of the Reorganizations on Life Sciences , Technology ’s or Growth’s shareholders with respect to any asset as to which unrealized gain or loss is required to be recognized for federal income tax purposes at the end of a taxable year (or on the termination or transfer thereof) under a mark-to-market system of accounting.
 
The parties have agreed to cooperate to facilitate the orderly reorganization of Life Sciences and Technology into Growth. It is anticipated that this transition will include the purchase and sale of certain portfolio securities of Life Sciences and Technology prior to the Reorganizations, which could increase the Acquired Funds' transition costs.  The sale of securities may result in the realization of capital gains to Life Sciences and Technology that, to the extent not offset by capital losses, would be distributed to shareholders prior to the Closing Date.
 
Life Sciences and Technology had unutilized capital loss carryovers as of the end of its fiscal year. The final amount of unutilized capital loss carryovers for Life Sciences and Technology is subject to change and will not be determined until the time of the Reorganizations.

Growth may be limited under Section 382 of the Code in its use of Life Sciences’ or Technology’s capital loss carryovers. However, the amount of capital loss carryovers of Life Sciences and Technology that will transfer to Growth and any such limitations on Growth’s use of such capital loss carryovers cannot be determined until the Closing Date of the Reorganizations.

INFORMATION ABOUT THE FUNDS
 
General Information
 
This Proxy Statement/Prospectus is being furnished in connection with the solicitation of proxies by the Boards. Proxies may be solicited by officers or employees of the Funds, American Century, their affiliates, as well as any proxy solicitation firm hired by American Century. Additionally, financial intermediaries may solicit the votes of the beneficial owners of the Funds. It is anticipated that the solicitation of proxies will be primarily by mail, internet, telephone, facsimile or personal interview. Shareholders who communicate proxies by telephone or by other electronic means have the same power and authority to issue, revoke or otherwise change their voting instructions as shareholders submitting proxies in written form. Telephonic solicitations will follow procedures designed to ensure accuracy and prevent fraud. American Century or an affiliate thereof may reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation materials to beneficial owners of American Century shares, and may reimburse certain officers or employees that it may employ for their reasonable expenses in assisting in the solicitation of proxies from such beneficial owners. American Century Services, LLC, the transfer agent and administrator of the Funds, has entered into a contract with Broadridge pursuant to which Broadridge will provide certain project management, telephone solicitation, and internet and telephone voting services in addition to providing for the printing and mailing of the proxy statement/prospectus. The estimated fee to b e paid to Broadridge by American Century Services, LLC is $42,650 in the aggregate.
 
 
Date, Time and Place of Meeting
 
The Meeting will be held on May 5, 2009 at the principal executive offices of American Century, 4500 Main Street, Kansas City, Missouri 64111 at 10:00 a.m. Central Time.
 
 
Use and Revocation of Proxies
 
A shareholder executing and returning a proxy has the power to revoke it at any time prior to its exercise by executing a superseding proxy (i.e., a later-dated and signed proxy), by submitting a notice of revocation to the Corporate Secretary of the Funds or by subsequently registering his or her vote by telephone or over the Internet. In addition, although mere attendance at the Meeting will not revoke a proxy, a shareholder of record present at the Meeting may withdraw his or her proxy and vote in person. All shares represented by properly executed proxies received at or prior to the Meeting, unless such proxies previously have been revoked, will be voted at the Meeting in accordance with the directions on the proxies; if no direction is indicated on a properly executed proxy, such shares will be voted “FOR” the Reorganizations. It is not anticipated that any matters other than the approval of the Reorganizations will be brought before the Meeting. If, however, any other business properly is brought before the Meeting, proxies will be voted in accordance with the judgment of the persons designated on such proxies.
 
 
Voting Rights and Required Votes
 
A quorum of shareholders is necessary to hold a valid meeting. Shareholders entitled to vote one-third of the issued and outstanding shares of each of Life Sciences and Technology must be present in person or by proxy, to constitute a quorum for purposes of voting on proposals relating to each Fund. Each shareholder is entitled to one vote per dollar of NAV represented by their shares, with fractional dollars voting proportionally. Shareholders of each affected Fund vote separately on whether to approve the Reorganization s , and the consummation of any one Reorganization is not a condition for approving the other Reorganization. Approval of the Reorganizations requires the approval of the lesser of (i) more than 50% of the outstanding shares of the applicable Fund or (ii) 67% or more of the shares of that Fund present or represented by proxy at the Meeting if more than 50% of such shares are present or represented by proxy. Broker-dealer firms or other financial intermediaries holding shares of any of the Funds in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares before the Meeting. Each Fund will include shares held of record by broker-dealers as to which such authority has been granted in its tabulation of the total number of shares present for purposes of determining whether the necessary quorum of shareholder exists. Properly executed proxies that are returned but that are marked “abstain” or with respect to which a broker - dealer has declined to vote on any proposal (“broker non-votes”) will be counted as present for the purposes of determining a quorum. Abstention s and broker non-votes (if applicable) will have the same effect as a vote against a proposal. If, by the time scheduled for the Meeting, sufficient votes in favor of approval of a proposal have not been received from the shareholders of the applicable Fund, the persons named as proxies may propose one or more adjournments of such Meeting, without further notice, to permit further solicitation of proxies from shareholders. According to the Bylaws of Life Sciences and Technology, any meeting at which a quorum is not present can be adjourned by a majority of the voting stock represented in person or by proxy until a quorum shall be present or represented. A meeting may be adjourned without additional notice, other than announcement at the meeting, for up to 90 days.

The vote of any such person could have a more significant effect on matters presented at a shareholder’s meeting than votes of other shareholders. The Funds are unaware of any shareholders, beneficial or of record, who own more than 25% of the voting securities of a Corporation. As of [date], 2009, the officers and directors of the Funds, as a group, owned less than 1% of any Fund’s outstanding shares.

ARTICLE I
 
TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ACQUIRING FUND SHARES AND LIQUIDATION OF THE ACQUIRED FUND
 
1.1             THE EXCHANGE.  Subject to the terms and conditions contained herein and on the basis of the representations and warranties contained herein, the Acquired Fund agrees to transfer all of its assets, as set forth in paragraph 1.2, to the Acquiring Fund.  In exchange, the Acquiring Fund agrees to deliver to the Acquired Fund the number of full and fractional Acquiring Fund Shares, determined by dividing the assets of the Acquired Fund, computed in the manner and as of the time and date set forth in paragraph 2.1 by the net asset value per share of the Acquiring Fund Shares computed in the manner and as of the time and date set forth in paragraph 2.2.

b)
No gain or loss will be recognized by the Acquiring Fund upon the receipt of the assets of the Acquired Fund solely in exchange for Acquiring Fund Shares.
 
c)

No gain or loss will be recognized by any Acquired Fund Shareholder upon the exchange of its Acquired Fund Shares for Acquiring Fund Shares.

Such opinion shall be based on customary assumptions and such representations as Reed Smith LLP may reasonably request, and the Acquired Fund and Acquiring Fund will cooperate to make and certify the accuracy of such representations.  The foregoing opinion may state that no opinion is expressed as to the effect of the Reorganization on the Acquiring Fund, the Acquired Fund or any Acquired Fund Shareholder with respect to any asset as to which unrealized gain or loss is required to be recognized for federal income tax purposes at the end of a taxable year (or on the termination or transfer thereof) under a mark-to-market system of accounting.  Notwithstanding anything herein to the contrary, neither the Acquiring Fund nor the Acquired Fund may waive the conditions set forth in this paragraph 8.5.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE

 
Growth
 
 
Market Perspective
 
By Steve Lurito, Chief Investment Officer, U.S. Growth Equity

 
The Perfect Storm
 
The year ended October 31, 2008, was one of the most turbulent periods for the U.S. equity market since the Great Depression. As the accompanying table shows, stocks declined sharply across the board as a “perfect storm” of negative influences undermined investor confidence and produced a dramatic increase in market volatility.
 
The biggest impact came from the credit crisis that grew out of the housing and mortgage meltdowns in 2007. Credit conditions deteriorated throughout the one-year period, culminating in a liquidity crisis that led to the downfall of a number of major financial companies. Examples included the government conservatorship of mortgage lenders Fannie Mae and Freddie Mac, the bankruptcy of brokerage firm Lehman Brothers, and the government bailout of insurer American International Group. Despite efforts by the U.S. government and Federal Reserve to provide systemic stability, the credit markets remained frozen.
 
Diminishing economic activity also weighed on the stock market. After decelerating in 2007, the U.S. economy weakened further in 2008 as consumer spending stalled, the housing downturn worsened, and the unemployment rate reached its highest level since 1994. The U.S. economic slowdown spread to other parts of the world, increasing the likelihood of a global recession.
 
One other noteworthy factor was the parabolic rise and fall of commodity prices. Robust growth in emerging economies boosted the prices of energy and many other commodities to record highs by mid-2008. However, the global economic slowdown led to a sharp reversal in commodity prices during the last few months of the period.
 
The Groundwork for Recovery
 
The events of the past year have been about correcting global imbalances and domestic excesses—the first step on the road to recovery. It’s important to remember that the stock market is a discounting mechanism, trading on estimates of future earnings power. The market decline over the past year discounted the current economic slowdown; similarly, we would expect the market to rebound before we see improvement in the economic data. We don’t know when this will happen, but the preconditions—significant monetary stimulus and low valuations—are in place.

Growth  - Portfolio Commentary
 
Portfolio Managers: Greg Woodhams and Prescott LeGard

Performance Summary
 
Growth returned –33.86%* during the 12 months ended October 31, 2008. By comparison, Growth outperformed its benchmark—the Russell 1000 Growth Index—and the Lipper Large-Cap Growth Funds category average, which returned –36.95% and –38.55%,** respectively. See the previous page for the portfolio’s long-term performance compared with its benchmark.
 
The portfolio declined in a year of unprecedented turmoil in financial markets. No sector contributed positively to absolute returns; information technology shares detracted most. Growth held up better than the Russell index thanks to contributions from a number of sectors, led by consumer discretionary, financials, and materials shares. Information technology and industrials were the only sectors to detract from relative results.
 
Consumer Discretionary Contributed Most
 
Outperformance in the consumer discretionary sector was driven by stock picks in the multiline and specialty retail industries. The sector was home to the number-one overall contributor to relative results, an overweight position in Family Dollar Stores. In the specialty retail segment, performance benefited from larger-than-benchmark weightings in Urban Outfitters and The TJX Companies, which operates the T.J. Maxx and Marshalls chains, among others. Having exposure to these and other discount retailers during the period benefited portfolio performance in this difficult economic environment.
 
For example, in the consumer staples sector, Wal-Mart saw increased customer traffic while continuing to make progress on its turnaround. Wal-Mart was a top-five contributor to portfolio performance.

Other Key Contributors
 
Financials shares also helped relative performance, thanks to stock selection in the insurance space, as well as underweight positions in consumer finance and thrifts. The key contribution to relative results came from an overweight position in Chubb Corporation. Chubb had an essentially flat return during an otherwise very difficult year for financials stocks because it’s seen as a well-capitalized, higher-quality name.
 
Materials shares also helped relative performance, led by stock selection. Monsanto, the world’s largest seed producer, was the leading contributor in this space. It also helped to be underweight in the chemicals and metals and mining industries, which suffered from falling commodity prices and the outlook for slower economic growth and tighter credit. The portfolio had no exposure to the poorest-performing fertilizer and steel companies, led by Mosaic and U.S. Steel, respectively.

 
IT, Industrials Detracted
 
The information technology sector was the largest detractor from relative return. Stock selection in the software industry hurt performance, behind an underweight position in Microsoft, which was seen as a “safe haven” during the market turmoil. An underweight position and stock selection in IT services also detracted. Here it hurt to be underrepresented in IBM, another big safe-haven play, and overweight in Western Union and DST Systems during the period.
 
The industrial sector underperformed due to positioning in the electrical equipment, commercial services, road and rail, and building products industries. Stock selection was mixed, but allocation detracted—the portfolio was overweight the poor-performing electrical  equipment companies, and underrepresented in the other industry segments, which held up better.

Outlook
 
The Growth team’s investment process focuses on large companies exhibiting sustainable improvement in their businesses. The managers have a thesis on each stock they own and devote their entire research effort toward identifying the companies in each sector and industry that they feel are likely to outperform. It is the managers’ belief that owning such companies will generate outperformance over time versus the Russell 1000 Growth Index and the other funds in the large-growth peer group.
 
As a result, the portfolio’s sector and industry selection as well as capitalization range allocations are primarily a result of identifying what the managers believe to be superior individual securities. As of October 31, 2008, they found opportunity in the health care and consumer discretionary sectors, the portfolio’s largest overweight positions. The most notable sector underweights were in information technology and energy shares.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE
 
Life Sciences Fund
 
Technology Fund
 
 
Market Perspective
 
By Enrique Chang, Chief Investment Officer, American Century Investments

 
Financial Storm Sank Stocks
 
The year ended November 30, 2008, represented one of the most tumultuous periods in the history of the U.S. equity market as an ongoing financial storm and a recession battered the stock market.
 
Continued deterioration in the credit environment and a deepening liquidity crisis—ignited by last year’s mortgage-market meltdown—led to an increasingly urgent need for capital at many major financial companies. By September, the crisis reached a tipping point as a number of major financial institutions filed for bankruptcy, sold out to competitors to avoid insolvency, or were taken over by the federal government.
 
The U.S. economy, which officially entered a recession in December 2007, grew even more sluggish. Steady job losses pushed the unemployment rate up to a 15-year high, consumer spending slowed dramatically, and mortgage foreclosures and delinquencies rose markedly. In addition, the financial crisis spread around the world, increasing the likelihood of a global economic downturn. On the positive side, the slowing economic environment brought the prices of energy and other commodities down sharply from record highs reached during the summer.
 
The troubling financial and economic news led to an unprecedented level of stock market turbulence. Day-to-day volatility increased dramatically as investor confidence faltered, producing a market storm that has not been seen since the 1930s. Stocks declined in five of the last six months of the period, with October producing the worst monthly performance in 21 years and one of the 10 worst months in the stock market’s history.

Intervention and Resiliency
 
As business and economic conditions worsened, intervention increased. The U.S. government and the Federal Reserve have provided extraordinary levels of fiscal and monetary assistance, and other central banks and governments have contributed additional stimulus.
 
Furthermore, downturns play the sometimes necessary role of correcting past market misbehavior and eliminating excesses and inefficiencies. The current downturn was years in the making, so it may take some time before we are firmly on the road to recovery. However, we remain confident in the stock market’s long-term resiliency.

Life Sciences   Portfolio Commentary
 
Portfolio Managers: Arnold Douville and Christy Turner*

Performance Summary
 
Life Sciences returned –28.17%** for the 12 months ended November 30, 2008. The portfolio’s benchmark, the S&P Composite 1500 Health Care Index, returned –30.45%. The broader equity market, represented by the S&P 500 Index, returned –38.09%.
 
Anxieties surrounding the economic slowdown and global financial market distress undermined the broader U.S. equity market during the period. Although inflationary worries eased in the final months of the reporting period, tighter credit conditions increasingly restricted access to operating capital and fueled investor pessimism. Befitting its reputation as a “safe haven” in volatile times, the health care sector outperformed the broader stock market. Nevertheless, every health care industry represented in the benchmark and the portfolio posted a negative total return for the 12-month period, with most posting double digit losses.
 
 
Stock Selection Drove Results
 
Stock selection in the health care industry accounted for the majority of the portfolio’s outperformance compared to the benchmark. Additionally, an underweight position in health care providers and services and an overweight position in health care equipment contributed positively to the portfolio’s relative performance.
 
Despite realizing positive effects from stock selection, our pharmaceuticals component, the portfolio’s largest industry weighting, detracted from relative performance due to our underweight position. Our stock selection in the biotechnology industry, the portfolio’s second-largest weighting, was a negative influence on performance.

Sleep Disorder Company Was Top Stock
 
The health care equipment category was home to Respironics, the portfolio’s top contributor to relative performance. We maintained an overweight position in the company, a manufacturer of respiratory products for sleep disorders, which reported record earnings and revenue growth before being acquired by Royal Philips Electronics.
 
In the pharmaceuticals area, our out-of-benchmark positions in Israel ’s Teva Pharmaceutical Industries, a generic drug manufacturer, and the United Kingdom ’s Elan Corp., a biopharmaceuticals company, boosted performance. Teva reported higher sales and continued success with its multiple sclerosis drug and its inhalers. Elan rallied on encouraging results for its investigational Alzheimer’s disease drug and on prescription increases for its multiple sclerosis treatment.
 
Our small, out-of-benchmark position in Sigma-Aldrich, a supplier of biochemicals and organic chemicals to the life sciences industry, was a top contributor to relative performance during the period. The company reported improved margins, cash flow, and sales combined with a steady increase in its emerging-markets business.

Underweights in Key Companies Detracted
 
Our underweight positions in Johnson & Johnson, the health care products and pharmaceuticals giant, and Amgen, a biotechnology company, represented the largest detractors to relative performance. Both companies were among the largest holdings in the portfolio, but they were underweighted compared with the benchmark. From a relative perspective, Johnson & Johnson benefited from its blue-chip status in a fairly recession-proof industry. Amgen benefited, on a relative basis, from solid earnings and positive phase 3 data for its pipeline product, denosumab, which treats low bone mass.
 
Our portfolio-only position in Switzerland ’s Alcon, a surgical equipment and consumer eye-care products manufacturer, also detracted from results. Shares fell sharply after the company cut its revenue outlook. Alcon attributed the revised forecast to currency fluctuations tied to the strengthening U.S. dollar and to slowing U.S. prescription sales.
 
Outlook
 
Regardless of the macroeconomic environment, we will continue to emphasize companies from across the health care spectrum exhibiting accelerating earnings and reasonable valuations. Our investment decisions may result in shifts in industry weightings, but any such developments stem from a fundamental, bottom-up assessment of each company’s merits.

Technology Portfolio Commentary
 
Portfolio Manager: Tom Telford*

Performance Summary
 
 
Technology returned –51.13%** for the 12 months ended November 30, 2008. The portfolio’s benchmark, the S&P Composite 1500 Technology Index, returned –43.26%. The broader equity market, represented by the S&P 500 Index, returned –38.09%.
 
The global credit crisis culminated late in the period with a series of extraordinary corporate failures and takeovers and government intervention. These events triggered a widespread stock market downturn that significantly magnified the losses experienced earlier in the period. Growth stocks underperformed value stocks across the capitalization spectrum, as the sectors closely aligned with business and consumer spending suffered the most.
 
 
Stock Selection Hampered Results
 
Stock selection accounted for the portfolio’s underperformance relative to the benchmark. Specifically, our stocks in the IT services and software industries were among the largest detractors. In the IT services sector, our underweight position in IBM landed the computer manufacturer among the portfolio’s largest detractors to relative performance. Similarly, in the software industry, which ended the period as the portfolio’s largest sector, our underweighted position in Microsoft was the top detractor to relative results. The company reported healthy earnings throughout the reporting period, which helped its stock performance. But, as with most stocks, IBM and Microsoft declined in the final months of the period, due to dismal economic forecasts and the broad-based stock market sell-off.

After delivering strong performance in 2007 and early 2008, our position in Canada’s Research In Motion, the maker of the BlackBerry handheld device and one of the largest holdings in the portfolio, represented the greatest individual performance detractor for the 12-month period. Shares nose-dived after the company warned that new-product-related spending would erode profit margins. Concerns about the global economic slowdown also weighed on the stock price.

Portfolio-only Positions Helped Performance
 
From a sector perspective, our small, portfolio-only exposure to the industrials and consumer discretionary sectors represented the greatest contributors to relative performance. For example, in the industrials sector, Japan ’s Nissha Printing was among the portfolio’s top contributors to relative performance. The company, which engages in printing and publishing for industrial materials and electronic products, raised its dividend payment and revenue outlook, and announced a joint venture with a Tokyo-based internet and printing-related business.

In the electronic equipment industry, our small, out-of-benchmark position in Cogent, Inc., a provider of automated fingerprint identification systems, was the portfolio’s leading contributor to relative performance. The company advanced on strong earnings and sales growth, soaring demand for its products, and management’s stock buyback plan.

Outlook
 
We will continue to focus on technology firms with accelerating earnings and revenue growth rates and positive share-price momentum, as we believe such stocks will generate superior returns over time. As recent results demonstrate, sector funds can show strong volatility to the up- and downsides. Therefore, it may be best to use such funds in the context of a larger, long-term, growth-oriented strategy.

Total return assumes reinvestment of net investment income and capital gains distributions, if any. The total return of the classes may not precisely reflect the class expense differences because of the impact of calculating the net asset values to two decimal places. If net asset values were calculated to three decimal places, the total return differences would more closely reflect the class expense differences. The calculation of net asset values to two decimal places is made in accordance with SEC guidelines and does not result in any gain or loss of value between one class and another.

Each 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
Each 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) except that the funds may concentrate their investments in securities of issuers as follows: engaged in the technology or telecommunications industries and related industry groups (Technology only); or engaged in the medical and health care industry and related industry groups (Life Sciences only) .
Underwriting
Each 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
Each 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
Each Fund may not invest for purposes of exercising control over management.
 
For purposes of the investment policy relating to concentration, a fund (except Life Sciences and Technology) 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.
 
Growth is diversified as defined in the Investment Company Act of 1940. 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). Life Sciences and Technology are nondiversified. Nondiversified means that a fund may invest a greater portion of its assets in a smaller number of securities than a diversified fund. Although Life Sciences’ and Technology’s portfolio managers expect that the Funds will ordinarily satisfy the requirements of a diversified fund, their nondiversified status gives each Fund more flexibility to invest heavily in the most attractive companies identified by its methodology.

In addition, the Funds are subject to the following investment limitations that are not fundamental and may be changed by the Board of Directors. The non-fundamental investment limitations of the Funds are substantially similar.
 
Subject
Policy
Leveraging
Each Fund may not purchase additional investment securities at any time during which outstanding borrowings exceed 5% of the total assets of the Fund.
 
Liquidity
Each 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
Each 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
Each 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
and
Options
Each Fund may enter into futures contracts and write and buy put and call options relating to futures contracts. Each 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
Limited
Operating
Histories
Each Fund may invest in the equity securities of issuers with limited operating histories. An issuer is considered to have a limited operating history if that issuer has a record of less than three years of continuous operation. Periods of capital formation, incubation, consolidations, and research and development may be considered in determining whether a particular issuer has a record of three years of continuous operation.

b.
Non-Daily Dividend Funds .  The gross income, realized and unrealized capital gains and losses and expenses (other than Class Expenses) of each Fund, other than the Daily Dividend Funds, shall be allocated to each class on the basis of its net asset value relative to the net asset value of the Fund.  Expenses to be so allocated also include Issuer Expenses and Fund Expenses.
 
-5-

 
c.
Apportionment of Certain Expenses .  Expenses of a Fund shall be apportioned to each class of shares depending on the nature of the expense item.  Issuer Expenses and Fund Expenses will be allocated among the classes of shares pro rata based on their relative net asset values in relation to the net asset value of all outstanding shares in the Fund.  Approved Class Expenses shall be allocated to the particular class to which they are attributable.  In addition, certain expenses may be allocated differently if their method of imposition changes.  Thus, if a Class Expense can no longer be attributed to a class, it shall be charged to a Fund for allocation among classes, as determined by the Advisor.

d.            Definitions .

(1)            Issuer Expenses .  “Issuer Expenses” include expenses of the Issuer that are not attributable to a particular Fund or class of a Fund.  Issuer Expenses include fees and expenses of those Independent Directors, including counsel fees for the Independent Directors, and certain extraordinary expenses of the Issuer that are not attributable to a particular Fund or class of a Fund.

(2)            Fund Expenses .  “Fund Expenses” include expenses of the Issuer that are attributable to a particular fund but are not attributable to a particular class of the Fund.  Fund Expenses include (i) interest expenses, (ii) taxes, (iii) brokerage expenses, and (iv) certain extraordinary expenses of a Fund that are not attributable to a particular class of a Fund.

(3)            Class Expenses .  “Class Expenses” are expenses that are attributable to a particular class of a Fund and shall be limited to: (i) applicable unified fee; (ii) payments made pursuant to the 12b-1 Plan of each applicable Class; and (iii) certain extraordinary expenses of an Issuer or Fund that are attributable to a particular class of a Fund.

(4)            Extraordinary Expenses .  “Extraordinary expenses” shall be allocated as an Issuer Expense, a Fund Expense or a Class Expense in such manner and utilizing such methodology as the Advisor shall reasonably determine, which determination shall be subject to ratification or approval of the Board and shall be consistent with applicable legal principles and requirements under the 1940 Act and the Internal Revenue Code, as amended.  The Advisor shall report to the Board quarterly regarding those extraordinary expenses that have been allocated as Class Expenses.  Any such allocations shall be reviewed by, and subject to the approval of, the Board.

Section 4.           Exchange Privileges

Subject to the restrictions and conditions set forth in the Funds’ prospectuses, shareholders may (i) exchange shares of one class of a Fund for shares of the same class of another Fund, (ii) exchange Investor Class shares for shares of any fund within the American Century family of funds that only offers a single class of shares (a “Single Class Fund”), and (iii) exchange shares of any Single Class Fund for Investor Class shares of another Fund, provided that the amount to be exchanged meets the applicable minimum investment requirements and the shares to be acquired in the exchange are qualified for sale in the stockholder's state of residence.
 
-6-


Section 5.           Conversion Features

Conversions from one class of a Fund’s shares into another class of shares are not permitted; provided , however , that if a shareholder of a particular class is no longer eligible to own shares of that class, upon prior notice to such shareholder, those shares will be converted to shares of the same Fund but of another class in which such shareholder is eligible to invest.  Similarly, if a shareholder becomes eligible to invest in shares of another class that has lower expenses than the class in which such shareholder is invested, such shareholder may be eligible to convert into shares of the same Fund but of the class with the lower expenses.

Section 6.           Quarterly and Annual Reports

The Board shall receive quarterly and annual reports concerning all allocated Class Expenses and distribution and servicing expenditures complying with paragraph (b)(3)(ii) of Rule 12b-1, as it may be amended from time to time.  In the reports, only expenditures properly attributable to the sale or servicing of a particular class of shares will be used to justify any distribution or servicing fee or other expenses charged to that class.  Expenditures not related to the sale or servicing of a particular class shall not be presented to the Board to justify any fee attributable to that class.  The reports, including the allocations upon which they are based, shall be subject to the review and approval of the Independent Directors of the Issuer who have no direct or indirect financial interest in the operation of this Plan in the exercise of their fiduciary duties.

Section 7.           Waiver or Reimbursement of Expenses

Expenses may be waived or reimbursed by any adviser to the Issuer, by the Issuer’s underwriter or by any other provider of services to the Issuer without the prior approval of the Board, provided that the fee is waived or reimbursed to all shares of a particular Fund in proportion to their relative average daily net asset values.

Section 8.           Effectiveness of Plan

Upon receipt of approval by votes of a majority of both (a) the Board and (b) the Independent Directors, this Plan shall become effective September 4, 2007.

Section 9.           Material Modifications

This Plan may not be amended to modify materially its terms unless such amendment is approved a majority of both (a) the Board and (b) the Independent Directors; provided ; however ; that a new Fund may be added by the Issuer upon approval by that Issuer’s Board by executing a new Schedule A to this Plan.

Ladies and Gentlemen:

I have acted as counsel to American Century Mutual Funds, Inc., a Maryland corporation (the "Company"), in connection with the Company's Registration Statement on Form N-14 (File No. 2-14213), which relates to the Company's authorized shares of common stock, par value One Cent ($0.01) per share (the "Shares"), proposed to be issued in accordance with the terms of the Agreements and Plans of Reorganization (the "Agreements") relating to the proposed reorganizations of the Life Sciences Fund and the Technology Fund into the Growth Fund (collectively, the "Reorganizations").

In connection with rendering the opinions set forth below, I have examined the Registration Statement, including a form of the Agreements, which is being filed as an exhibit thereto; the Company's Articles of Incorporation, Articles Supplementary and Bylaws, as reflected in the Company's corporate records; resolutions of the Board of Directors of the Company relating to the approval of the Reorganizations and the issuance of the Shares; and such other documents as I deemed relevant.  In conducting my examination, I have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity, accuracy and completeness of documents purporting to be originals and the conformity to originals of any copies of documents.  I have not independently established any facts represented in the documents so relied on.

I am a member of the Bar of the State of Missouri.  The opinions expressed in this letter are based on the facts in existence and the laws in effect on the date hereof and are limited to the laws (other than the conflict of law rules) of the State of Maryland that in my experience are normally applicable to the issuance of shares by registered investment companies organized as corporations under the law of that state and to the Securities Act of 1933, as amended (the "1933 Act"), the Investment Company Act of 1940, as amended (the "1940 Act"), and the regulations of the Securities and Exchange Commission (the "SEC") thereunder. I express no opinion with respect to any other laws.

Based upon and subject to the foregoing and the qualifications set forth below, it is my opinion that:

1.           The issuance of the Shares in connection with the Reorganizations has been duly authorized by the Company.

2.           When issued upon the terms provided in the Registration Statement, subject to compliance with the 1933 Act, the 1940 Act, and applicable state laws regulating the offer and sale of securities, and assuming the continued valid existence of the Company under the laws of the State of Maryland, the Shares will be validly issued, fully paid and non-assessable.

For the record, it should be stated that I am an employee of American Century Services, LLC, an affiliate of the Company's investment advisor.
