Market Perspective [photo of Mark Mallon] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

As outlined in the Market Perspective on page 2, a pause in the Federal Reserve's interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. We'll discuss why Ultra didn't match those returns and what we're doing to address that issue. MANAGEMENT CHANGES, PROCESS ENHANCEMENTS Tom Telford joined Ultra as co-portfolio manager at the beginning of July, replacing Bruce Wimberly. A 10-year American Century veteran, Tom previously served as co-manager on three of the company's growth portfolios. He continues managing the American Century Technology Fund but has relinquished his previous portfolio management roles. Wade Slome and Jerry Sullivan remained co-managers of Ultra in the reporting period. Upon reviewing our investment strategy, we have developed several process enhancements to more successfully identify and invest in companies exhibiting improving fundamentals and stock price momentum. Ultra built its reputation by focusing on those two factors; the process enhancements simply provide a more sophisticated means of capturing the upside performance potential those factors offer. REASONS ULTRA UNDERPERFORMED Ultra's underperformance in the 12-month period largely reflected an overweight portfolio allocation and unfavorable security selection in two traditional growth-stock sectors -- information technology and consumer discretionary -- that performed relatively poorly until late in the period. It also reflected underweight allocations in industrials and materials, sectors the market favored in the first half of the reporting period, when they benefited from rising commodity prices and capital investment. The same sectors that caused most of Ultra's relative underperformance also detracted from its total return.

(continued) - ------ 5 Ultra - Portfolio Commentary the portfolio realized positive contributions from financial stocks, primarily commercial banks and diversified financial services firms that benefited from relatively stable interest rates in a growing economy. Stakes in wireless telecommunications companies also limited the portfolio's absolute losses, as did its few investments in the industrials sector. LAGGING -- AND LEADING -- INDIVIDUAL PERFORMERS During the latest reporting period, Internet-related businesses accounted for three of our four worst relative individual performers. Those stocks -- eBay, Yahoo! and Amazon.com -- all encountered mounting revenue and competition concerns. With our focus on stocks exhibiting price momentum and accelerating financial features, we reduced or eliminated our stakes in those companies. Ultra's second-biggest individual overweight holding, Teva Pharmaceuticals, also ranked among its top five leading detractors. The generic drug maker's stock fell 13% in the period as larger branded-drug rivals, including Merck, introduced generic versions of their own drugs to limit Teva's market presence. Fortunately, Ultra's largest average overweight holding, International Game Technology, topped its list of best, not worst, performers. Shares in the slot-machine maker surged 63% as global demand for gaming machines continued to expand. PORTFOLIO OBJECTIVE & EXPECTATIONS Ultra seeks long-term capital appreciation for investors who can tolerate short-term share price fluctuation. As part of a diversified investment portfolio, Ultra provides consistent exposure to large-cap growth stocks. We pursue our objective by investing in companies with improving business fundamentals and the ability to sustain above-average growth rates over time. Our approach seeks industry leaders with competitive advantages, strong management, and a solid financial picture that can support continued improvement and growth. We believe investments in such firms will generate long-term benefits for investors.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 7 Shareholder Fee Example (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - ----------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - ----------------------------------------------------------------------------------- ULTRA SHAREHOLDER FEE EXAMPLE - ----------------------------------------------------------------------------------- ACTUAL - ----------------------------------------------------------------------------------- Investor Class $1,000 $954.80 $4.88 0.99% - ----------------------------------------------------------------------------------- Institutional Class $1,000 $956.00 $3.89 0.79% - ----------------------------------------------------------------------------------- Advisor Class $1,000 $953.90 $6.11 1.24% - ----------------------------------------------------------------------------------- C Class $1,000 $949.80 $9.78 1.99% - ----------------------------------------------------------------------------------- R Class $1,000 $952.60 $7.33 1.49% - ----------------------------------------------------------------------------------- HYPOTHETICAL - ----------------------------------------------------------------------------------- Investor Class $1,000 $1,020.21 $5.04 0.99% - ----------------------------------------------------------------------------------- Institutional Class $1,000 $1,021.22 $4.02 0.79% - ----------------------------------------------------------------------------------- Advisor Class $1,000 $1,018.95 $6.31 1.24% - ----------------------------------------------------------------------------------- C Class $1,000 $1,015.17 $10.11 1.99% - ----------------------------------------------------------------------------------- R Class $1,000 $1,017.69 $7.58 1.49% - ----------------------------------------------------------------------------------- *Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 8 Ultra - Schedule of Investments OCTOBER 31, 2006 Shares ($ IN THOUSANDS) Value - -------------------------------------------------------------------------------- COMMON STOCKS -- 98.4% AEROSPACE & DEFENSE -- 2.9% - -------------------------------------------------------------------------------- 2,419,000 Boeing Co. $ 193,181 - -------------------------------------------------------------------------------- 3,634,000 United Technologies Corp. 238,827 - -------------------------------------------------------------------------------- 432,008 - -------------------------------------------------------------------------------- AIR FREIGHT & LOGISTICS -- 1.8% - -------------------------------------------------------------------------------- 1,811,000 C.H.

------ 15 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Ultra Fund (the fund) is one fund in a series issued by the corporation. The fund is diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth. The fund pursues this objective by investing primarily in equity securities. The fund generally invests in equity securities of large companies, but may invest in companies of any size. The following is a summary of the fund's significant accounting policies. MULTIPLE CLASS -- The fund is authorized to issue the Investor Class, the Institutional Class, the Advisor Class, the C Class and the R Class. The C Class may be subject to a contingent deferred sales charge. The share classes differ principally in their respective sales charges and distribution and shareholder servicing expenses and arrangements. All shares of the fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; or trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. SECURITIES ON LOAN -- The fund may lend portfolio securities through its lending agent to certain approved borrowers in order to earn additional income. The fund continues to recognize any gain or loss in the market price of the securities loaned and records any interest earned or dividends declared. FUTURES CONTRACTS -- The fund may enter into futures contracts in order to manage the fund's exposure to changes in market conditions. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the fund is required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. The fund recognizes a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. (continued) - ------ 16 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The fund records the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The fund may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the fund's exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the fund and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The fund bears the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. (continued) - ------ 17 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee). The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of the fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in the fund's investment strategy (strategy assets) to calculate the appropriate fee rate for the fund. The strategy assets include the fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. Effective August 1, 2006, the fund modified its management fee schedule, resulting in lower fee rates. There was no significant impact on the effective annual management fee for the year ended October 31, 2006 resulting from this change. The annual management fee schedule for each class of the fund is as follows: - -------------------------------------------------------------------------------- INVESTOR, C AND R INSTITUTIONAL ADVISOR - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $5 billion 1.000% 0.800% 0.750% - -------------------------------------------------------------------------------- Next $5 billion 0.980% 0.780% 0.730% - -------------------------------------------------------------------------------- Next $5 billion 0.970% 0.770% 0.720% - -------------------------------------------------------------------------------- Next $5 billion 0.960% 0.760% 0.710% - -------------------------------------------------------------------------------- Next $5 billion 0.950% 0.750% 0.700% - -------------------------------------------------------------------------------- Next $5 billion 0.900% 0.700% 0.650% - -------------------------------------------------------------------------------- Over $30 billion 0.800% 0.600% 0.550% - -------------------------------------------------------------------------------- The effective annual management fee for each class of the fund for the year ended October 31, 2006 was 0.99%, 0.79%, 0.74%, 0.99% and 0.99% for the Investor Class, Institutional Class, Advisor Class, C Class and R Class, respectively. DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master Distribution and Shareholder Services Plan for the Advisor Class (the Advisor Class plan) and a separate Master Distribution and Individual Shareholder Services Plan for each of the C Class and R Class (collectively with the Advisor Class plan, the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the Advisor Class and C Class will pay American Century Investment Services, Inc. (ACIS) the following annual distribution and service fees: - -------------------------------------------------------------------------------- ADVISOR C - -------------------------------------------------------------------------------- Distribution Fee 0.25% 0.75% - -------------------------------------------------------------------------------- Service Fee 0.25% 0.25% - -------------------------------------------------------------------------------- The plans provide that the R Class will pay ACIS an annual distribution and service fee of 0.50%. The fees are computed and accrued daily based on each class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred in connection with distributing shares of the classes including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the fund. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers for Advisor Class shares and for individual shareholder services rendered by broker/dealers or other independent financial intermediaries for C Class and R Class shares. Fees incurred under the plans during the year ended October 31, 2006, are detailed in the Statement of Operations. (continued) - ------ 18 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement and securities lending agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchases and sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, were $11,330,795 and $17,217,382, respectively.

(2) Non-income producing. (3) Security, or a portion thereof, was on loan as of October 31, 2006. 7. SECURITIES LENDING As of October 31, 2006, securities in the fund valued at $408,144 were on loan through the lending agent, JPMCB, to certain approved borrowers. JPMCB receives and maintains collateral in the form of cash and/or acceptable securities as approved by ACIM. Cash collateral is invested in authorized investments by the lending agent in a pooled account. The value of cash collateral received at period end is disclosed in the Statement of Assets and Liabilities and investments made with the cash by the lending agent are listed in the Schedule of Investments. Any deficiencies or excess of collateral must be delivered or transferred by the member firms no later than the close of business on the next business day. The total value of all collateral received, at this date, was $413,770. The fund's risks in securities lending are that the borrower may not provide additional collateral when required or return the securities when due. If the borrower defaults, receipt of the collateral by the fund may be delayed or limited. 8. FEDERAL TAX INFORMATION The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 were as follows: - -------------------------------------------------------------------------------- 2006 2005 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - -------------------------------------------------------------------------------- Ordinary income $27,619 -- - -------------------------------------------------------------------------------- Long-term capital gains -- -- - -------------------------------------------------------------------------------- The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. Reclassification of $27,218, $(325,473), and $298,255 between undistributed net investment income, net realized gain (loss), and capital, respectively, include the difference in character of realized gains on redemptions in kind and net operating losses. (continued) - ------ 21 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 8. FEDERAL TAX INFORMATION (CONTINUED) As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- Federal tax cost of investments $12,137,552 ================================================================================ Gross tax appreciation of investments $3,390,282 - ---------------------------------------------------------- Gross tax depreciation of investments (48,457) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $3,341,825 ================================================================================ Net tax appreciation (depreciation) of derivatives and translation of assets and liabilities on foreign currencies -- - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $3,341,825 ================================================================================ Undistributed ordinary income -- - ---------------------------------------------------------- Accumulated long-term gains $1,001,155 - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on certain forward foreign currency contracts and return of capital dividends. 9. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. 10.

See Notes to Financial Statements. - ------ 27 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Ultra Fund, (the "Fund"), one of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for the periods presented. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Ultra Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Ultra (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of the advice of its independent counsel throughout the period. (continued) - ------ 32 Approval of Management Agreement for Ultra FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the fund. The Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance (continued) - ------ 33 Approval of Management Agreement for Ultra fell below the median for both the one and three year periods during part of the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvestment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. (continued) - ------ 34 Approval of Management Agreement for Ultra COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was below the median of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, (continued) - ------ 35 Approval of Management Agreement for Ultra provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, assisted by the advice of legal counsel independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor, negotiated changes to the breakpoint schedule used to calculate the management fee. These changes were proposed by the Directors based on their review of the competitive changes in the mutual fund marketplace and their review of financial information provided by the advisor. The new schedule, effective August 1, 2006, contains lower management fees at certain asset levels than under the existing structure. Following these negotiations with the advisor, the independent directors concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 36 Share Class Information Five classes of shares are authorized for sale by the fund: Investor Class, Institutional Class, Advisor Class, C Class and R Class. The total expense ratio of Institutional Class shares is lower than that of Investor Class shares. The total expense ratios of Advisor Class, C Class and R Class shares are higher than that of Investor Class shares. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. ADVISOR CLASS shares are sold primarily through institutions such as investment advisors, banks, broker-dealers, insurance companies, and financial advisors. Advisor Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. The total expense ratio of Advisor Class shares is 0.25% higher than the total expense ratio of Investor Class shares. C CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. C Class shares redeemed within 12 months of purchase are subject to a contingent deferred sales charge (CDSC) of 1.00%. There is no CDSC on shares acquired through reinvestment of dividends or capital gains. The unified management fee for C Class shares is the same as for Investor Class shares. C Class shares also are subject to a Rule 12b-1 distribution and service fee of 1.00%. R CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. The unified management fee for R Class shares is the same as for Investor Class shares. R Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. All classes of shares represent a pro rata interest in the fund and generally have the same rights and preferences. - ------ 37 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective [photo of Mark Mallon] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

Growth's longer-term performance also remained solid, with average annual returns in excess of its benchmark (see page 3) and the Morningstar category average, which were 4.24% and 5.93% for the five- and 10-year periods ended October 31, 2006, respectively. As outlined in the Market Perspective on page 2, a pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. On an absolute basis, every sector contributed to Growth's return except utilities, a tiny portion (less than 1%) of the fund and the index. Relative to its benchmark, Growth's outperformance resulted largely from effective stock selection across a wide range of sectors, including information technology, industrials, and energy, among others. Indeed, the portfolio's positions outperformed in all but two of the index's sectors -- financial stocks and utilities. INFORMATION TECHNOLOGY LED OUTPERFORMANCE Information technology stocks were the leading source of the portfolio's outperformance during the fiscal year. Stock selection in semiconductors contributed significantly, especially an overweight position in Freescale Semiconductor, a spin-off from Motorola producing chips for a number of wireless and industrial applications. Freescale performed well overall, and received an additional boost near the end of the period after agreeing to be acquired at a significant premium to its existing share price. Coupled with an underweight position in Intel, which performed poorly, these were two of the top-three contributors to relative returns. Growth also benefited from good stock selection in industrials. For the year, the industrial names in the portfolio were up 19% during the period, compared with 15% for those in the index.

(continued) - ------ 5 Growth - Portfolio Commentary Stock selection also had a positive effect in the energy sector, where performance was quite volatile quarter-to-quarter. In general, we avoided firms with exposure to the volatile North American natural gas market; instead, we favored service companies more closely tied to oil companies with well-financed capital expenditure budgets. As a result, Growth's energy holdings were up 20%, compared with 8% for this segment of the index. The portfolio's top contributor in this space was Schlumberger, a global oil-field-services provider that benefited from increased exploration for oil and gas given higher energy prices overall. That helped Schlumberger return 40% for the 12-month period. Finally, our top contributor for the 12 months was an overweight position in Archer-Daniels-Midland (ADM), which performed well on the strength of its oilseed and corn processing businesses. ADM drew additional investor interest during the period because it is a leading producer of ethanol, an alternative and additive to gasoline made from corn. FINANCIALS DETRACTED The portfolio's performance would have been even better relative to its benchmark but for positioning among financials shares. For the year, Growth's financial holdings were up 14%, compared with 18% for this portion of the index. Despite an overweight position in this sector, which was among the best-performing segments of the market for the year, disappointing stock selection limited Growth's relative return. In particular, positioning among capital markets shares -- the leading contributor to index returns from the financials sector -- detracted from relative performance. PORTFOLIO OBJECTIVE & EXPECTATIONS American Century Growth seeks long-term capital appreciation for investors who can tolerate short-term share price fluctuations. We pursue our objective by continuing to remain fully invested in large companies that are exhibiting sustainable improvement in their businesses. It is our belief that owning such companies will generate outperformance over time versus the Russell 1000 Growth Index and the other funds in our large-growth peer group.

PERFORMANCE SUMMARY Focused Growth returned 9.13% for the 12 months ended October 31, 2006, compared with the 13.57% return of its blended benchmark. The blended index's return reflects the performance of its equally weighted components, the Russell 1000 Growth Index and the S&P 500 Index, which rose 10.84% and 16.34%, respectively. At the same time, the 1,686 funds in the Morningstar Large Growth Funds category had an average return of 9.05%.* As outlined in the Market Perspective on page 2, a pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. In absolute terms, every stock sector made a positive contribution to Focused Growth's return for the year. But in relative terms, the portfolio trailed its benchmark primarily because of positioning among information technology and consumer discretionary shares. TOP CONTRIBUTORS One of the key contributors to both absolute and relative performance was Schlumberger, the largest position in the Focused Growth portfolio. This leading global oil-field-services provider benefited from increased exploration for oil and gas given higher energy prices overall. That helped Schlumberger return 40% for the 12-month period. Another of the portfolio's top contributors was food products firm Archer-Daniels-Midland (ADM), up almost 60% for the year. The company continued to perform well on the strength of its oilseed and corn processing businesses. ADM drew additional investor interest because it is a leading producer of the fossil fuel alternatives biodiesel and ethanol. In industrials, we favored stocks of companies that typically perform better late in economic cycles and that have less interest rate sensitivity, such as capital goods and aerospace and defense firms. Continental Airlines was among the portfolio's biggest contributors to both relative and absolute returns. The company is experiencing good yield and traffic trends, and has a relatively young, efficient fleet of planes. For the year, the stock was up 185%. INFORMATION TECHNOLOGY, CONSUMER DISCRETIONARY MIXED Despite positive stock selection in the information technology sector overall, Focused Growth's relative return was negatively impacted by some of our TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF % OF NET ASSETS NET ASSETS AS OF AS OF 10/31/06 4/30/06 - -------------------------------------------------------------------------------- Cisco Systems Inc. 4.4% 4.1% - -------------------------------------------------------------------------------- Textron Inc. 4.4% 4.2% - -------------------------------------------------------------------------------- Hewlett-Packard Co. 4.3% 4.1% - -------------------------------------------------------------------------------- Schering-Plough Corp. 4.3% -- - -------------------------------------------------------------------------------- Emerson Electric Co. 4.3% 4.3% - -------------------------------------------------------------------------------- Baxter International, Inc. 4.2% -- - -------------------------------------------------------------------------------- Wells Fargo & Co. 4.1% 1.3% - -------------------------------------------------------------------------------- St. Paul Travelers Companies, Inc.

(continued) - ------ 12 Focused Growth - Portfolio Commentary security selections. The two biggest detractors from performance were anti-virus software maker McAfee and communications equipment firm QUALCOMM Inc. McAfee's shares were hurt by concerns that Microsoft would enter the business. Our optimism about QUALCOMM Inc. and other holdings in the communications equipment industry due to the increasing adoption of high-volume wireless communications and rising global usage of the Internet was not rewarded during the period. However, the portfolio's top contributor to both relative and absolute returns also resided in the information technology space -- Broadcom, a leading chip manufacturer experiencing strong growth in wireless networking. Its products are used in everything from consumer electronics to Internet communications gear. Mixed returns were also the theme in the consumer discretionary sector, which was home to such significant detractors as Ross Stores, Target Corp., and Weight Watchers International. At the same time, such stocks as J.C. Penney and Polo Ralph Lauren were leading contributors on both a relative and absolute basis. Polo performed well during the period, announcing better-than-expected earnings and operating margin figures, as well as a share buyback plan. J.C. Penney continued to benefit from a decision to close underperforming stores. The firm announced better-than-expected same-store sales figures, as well as rapid growth in Internet sales, and lifted its earnings guidance. PORTFOLIO OBJECTIVE & EXPECTATIONS Focused Growth seeks long-term growth and is designed for investors who can tolerate short-term share price fluctuation as they seek to complement current holdings with an aggressive, concentrated growth investment. The portfolio remains fully invested in larger-sized companies that are exhibiting sustainable improvement in their business. We believe this approach will lead to outperformance over time. That said, shareholders should understand that Focused Growth is a non-diversified fund, meaning its holdings are typically limited to a core group of approximately 25-45 stocks. Stocks advancing in this concentrated portfolio, where a single holding may account for more than 5% of assets, will have a positive impact on performance. However, investors need to be prepared for the other side of the coin: if a large position stumbles, the effect is magnified.

As outlined in the Market Perspective on page 2, a pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. An overweight position in the wireless telecommunication industry and well-timed sector position shifts in industrials and information technology helped the portfolio outperform the Russell Midcap Growth Index. Relatively weaker returns in the health care and financials sectors contributed to modest underperformance compared with the overall Russell Midcap Index. It's worth noting that Heritage ranked in the top 18th (out of 997 funds), 35th (651 funds), and 37th (241 funds) percentiles among its Morningstar Mid-Cap Growth category, for the one-, five- and 10-year periods ended October 31, 2006,** respectively. INVESTMENT PROCESS PAID OFF For the second straight fiscal year, we reaped our biggest relative and absolute gains from an overweight stake in the wireless telecommunications industry. The portfolio's investments in that industry -- centered on two cellular providers in the Latin American market -- composed a significant share of the portfolio's total return. Meanwhile, our focus on companies with accelerating financial growth and share price momentum helped us adjust our weighting of two key sectors at opportune times. We raised our stake in industrials in the first half of the period, when rising commodity prices and capital investment boosted stocks in that sector. Later, in accordance with our investment process, we reduced our industrials exposure in the second half of the period, when the sector lost steam as the economy slowed. Likewise, we reduced our stake in information technology early in the reporting period, when the sector was out of favor. But as technology gained favor late in the period, we increased our exposure to the sector. For the full 12-month period, our underweight position in technology benefited the portfolio.

(continued) - ------ 18 Heritage - Portfolio Commentary contributors. The two cellular providers focused on the Latin American market, NII Holdings and America Movil SA de CV, accounted for a combined 11% of the portfolio's average weight in the 12-month period and represented the largest and third-largest overweight individual positions, respectively. They also finished first and second on the portfolio's list of top contributors, with NII's shares gaining 57% and America Movil's rising 68%. In addition to the cellular investments, top contributors included a stake in Aker Kvaerner ASA, a Norway-based maker of processing equipment for oil and gas companies. They also included a stake in Precision Castparts, a manufacturer of metal components for aerospace and industrial applications. Precision benefited from a rebound in aircraft industry orders. HEALTH CARE INFECTED RETURNS Five of the portfolio's 10 worst relative performers resided in the health care sector, where we maintained a detrimental overweight position. Prescription manager Caremark and managed care provider Aetna led the list of the sector's leading detractors. Shares in both declined as the entire health care services industry battled concerns about tightening profit margins and slowing increases in managed care premiums. An underweight stake in financials and weak security selection in that sector also reduced relative returns. Most of the sector benefited from relatively stable long-term interest rates, expectations of declining short-term interest rates in 2007, and sound market returns that bolstered interest in capital markets. Shares of Heritage's leading underperformer and one of its top 10 overweight positions, National Oilwell Varco, mostly reflected a downward trend in crude oil prices late in the 12-month period. PORTFOLIO OBJECTIVE & EXPECTATIONS Heritage is designed as a long-term growth component of a diversified investment portfolio. It's best suited for investors who are seeking to diversify larger-cap holdings and who can tolerate significant short-term price fluctuations. Our process focuses on medium-sized and smaller companies with accelerating earnings growth rates and share price momentum. We believe that active investing in such companies will generate outperformance over time compared with the Russell Midcap and Midcap Growth Indices.

Vista outperformed its benchmark in the first half of the reporting period as market returns moved higher and the portfolio benefited from overweight stakes in industrials, materials, and telecommunications. Those sectors exhibited attractive price momentum and improving financial returns, two factors crucial to Vista's investment process. However, the portfolio struggled on both an absolute and relative basis after the market sold off in May 2006. The broad market rebounded late in the reporting period after the Federal Reserve paused its two-year, interest rate-hike campaign in August. But the portfolio missed the rebound's gains. That's because the market's favor swung toward consumer-oriented and technology stocks, and our picks in those sectors did not perform well. Our underweight positions in energy, health care, and consumer discretionary further detracted from absolute and relative performance. SECTOR OVERWEIGHTS WORKED WELL The overweight positions that worked so well for the portfolio in early 2006 accounted for most of its positive contributions for the full 12-month reporting period. In telecom, Vista's entire stake centered on the wireless industry, including positions in two cellular providers, NII Holdings and America Movil SA de CV, focused on the Latin American market. Both stocks ranked among the portfolio's top three positions in the period, and they also ranked as the two leading individual contributors to its total return. Vista's biggest contributor to its relative return came from the materials sector. A large overweight position in the metals and mining industry benefited the portfolio, and no individual stock helped more than Titanium Metals. Shares in the maker of lightweight titanium materials surged 149%, reflecting ongoing strong demand from the aircraft industry. Vista also enjoyed solid returns from investments in steelmakers.

(continued) - ------ 24 Vista - Portfolio Commentary The portfolio's early 2006 focus on companies poised to benefit from increased business spending also led to solid returns in the industrials sector, specifically from an overweight position in construction and engineering. A stake in Foster Wheeler, one of the portfolio's top five overweight positions, performed well as shares in the builder of power plants and refineries advanced 59%. SECURITY SELECTION REDUCED RETURNS The portfolio's underperformance versus its benchmark stemmed primarily from stocks picks in health care, consumer discretionary and information technology. In financials, a sector that boosted the portfolio's total return, security selection also trimmed relative performance. In health care, an overweight position and poor security selection in health care providers and services hurt the portfolio, as did several stakes in makers of health care equipment and supplies. Meanwhile, weakness in technology spread across a number of industries and included a stake in Intergraph Corp., whose shares plunged in late January after the maker of operational software for businesses and governments reported a decline in quarterly revenue. The portfolio's worst performer, Houston-based natural gas producer Southwestern Energy, suffered from a substantial decline in natural gas prices. PORTFOLIO OBJECTIVE & EXPECTATIONS Vista is designed as a long-term growth component of a diversified investment portfolio for investors who can tolerate significant short-term price fluctuations. The portfolio adheres to an investment process that identifies mid-sized and smaller companies with accelerating earnings and revenue. We believe this selection strategy will produce solid, long-term gains for investors. We think the portfolio will perform well in a consistent, directional market, and we're encouraged by the market's behavior since the Fed paused its interest-rate hike campaign. Growth stocks traditionally have performed well after the Fed stops raising rates, and we believe our process works well in such an environment.

See Notes to Financial Statements. - ------ 28 Shareholder Fee Examples (Unaudited) Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 29 Shareholder Fee Examples (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - ------------------------------------------------------------------------------------------------ EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - ------------------------------------------------------------------------------------------------ GROWTH SHAREHOLDER FEE EXAMPLE - ------------------------------------------------------------------------------------------------ ACTUAL - ------------------------------------------------------------------------------------------------ Investor Class $1,000 $1,045.60 $5.16 1.00% - ------------------------------------------------------------------------------------------------ Institutional Class $1,000 $1,046.70 $4.13 0.80% - ------------------------------------------------------------------------------------------------ Advisor Class $1,000 $1,044.30 $6.44 1.25% - ------------------------------------------------------------------------------------------------ C Class $1,000 $1,040.00 $10.28 2.00% - ------------------------------------------------------------------------------------------------ R Class $1,000 $1,043.20 $7.72 1.50% - ------------------------------------------------------------------------------------------------ HYPOTHETICAL - ------------------------------------------------------------------------------------------------ Investor Class $1,000 $1,020.16 $5.09 1.00% - ------------------------------------------------------------------------------------------------ Institutional Class $1,000 $1,021.17 $4.08 0.80% - ------------------------------------------------------------------------------------------------ Advisor Class $1,000 $1,018.90 $6.36 1.25% - ------------------------------------------------------------------------------------------------ C Class $1,000 $1,015.12 $10.16 2.00% - ------------------------------------------------------------------------------------------------ R Class $1,000 $1,017.64 $7.63 1.50% - ------------------------------------------------------------------------------------------------ FOCUSED GROWTH SHAREHOLDER FEE EXAMPLE - ------------------------------------------------------------------------------------------------ ACTUAL - ------------------------------------------------------------------------------------------------ Investor Class $1,000 $1,017.80 $5.09 1.00% - ------------------------------------------------------------------------------------------------ HYPOTHETICAL - ------------------------------------------------------------------------------------------------ Investor Class $1,000 $1,020.16 $5.09 1.00% - ------------------------------------------------------------------------------------------------ * Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period.

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Growth Fund (Growth), Focused Growth Fund (Focused Growth), Heritage Fund (Heritage) and Vista Fund (Vista) (collectively, the funds) are four funds in a series issued by the corporation. Growth, Heritage and Vista are diversified under the 1940 Act. Focused Growth is nondiversified and normally limits its investments to a core group of approximately 25-45 common stocks. The funds' investment objective is to seek long-term capital growth. The funds pursue this objective by investing primarily in equity securities. Growth and Focused Growth generally invest in larger companies but may purchase companies of any size. Heritage and Vista generally invest in companies that are medium-sized and smaller at the time of purchase. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- Growth and Vista are authorized to issue the Investor Class, the Institutional Class, the Advisor Class, the C Class and the R Class. Focused Growth is authorized to issue the Investor Class. Heritage is authorized to issue the Investor Class, the Institutional Class, the Advisor Class and the C Class. The C Class may be subject to a contingent deferred sales charge. The share classes differ principally in their respective sales charges and distribution and shareholder servicing expenses and arrangements. All shares of each fund represent an equal pro rata interest in the assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the funds are allocated to each class of shares based on their relative net assets. Sale of the Investor Class for Focused Growth commenced February 28, 2005. Sale of R Class for Vista commenced July 29, 2005. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the funds determine that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The funds estimate the components of distributions received that may be considered nontaxable distributions or capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. FUTURES CONTRACTS -- The funds may enter into futures contracts in order to manage the funds' exposure to changes in market conditions. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the funds are required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation (continued) - ------ 37 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) margin) are made or received daily, in cash, by the funds. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. The funds recognize a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The funds record the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The funds may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the funds' exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the funds and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The funds bear the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. Each fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable each fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to each fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, each fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the funds. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. (continued) - ------ 38 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the funds, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of each specific class of shares of each fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in each fund's investment strategy (strategy assets) to calculate the appropriate fee rate for each fund. The strategy assets include each fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The annual management fee for each class of Focused Growth, Heritage and Vista was 1.00%, 0.80%, 0.75%, 1.00% and 1.00%, for the Investor Class, Institutional Class, Advisor Class, C Class and R Class, respectively, as applicable. The annual management fee schedule for each class of Growth is as follows: - -------------------------------------------------------------------------------- INVESTOR, C & R INSTITUTIONAL ADVISOR - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $5 billion 1.000% 0.800% 0.750% - -------------------------------------------------------------------------------- Next $5 billion 0.980% 0.780% 0.730% - -------------------------------------------------------------------------------- Next $5 billion 0.970% 0.770% 0.720% - -------------------------------------------------------------------------------- Next $5 billion 0.960% 0.760% 0.710% - -------------------------------------------------------------------------------- Next $5 billion 0.950% 0.750% 0.700% - -------------------------------------------------------------------------------- Next $5 billion 0.900% 0.700% 0.650% - -------------------------------------------------------------------------------- Over $30 billion 0.800% 0.600% 0.550% - -------------------------------------------------------------------------------- The effective annual management fee for each class of Growth for the year ended October 31, 2006 was 1.00%, 0.80%, 0.75%, 1.00% and 1.00%, for the Investor Class, Institutional Class, Advisor Class, C Class and R Class, respectively. DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master Distribution and Shareholder Services Plan for the Advisor Class (the Advisor Class plan) and a separate Master Distribution and Individual Shareholder Services Plan for each of the C Class and R Class (collectively with the Advisor Class Plan, the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the Advisor Class and C Class will pay American Century Investment Services, Inc. (ACIS) the following annual distribution and service fees: - -------------------------------------------------------------------------------- ADVISOR C - -------------------------------------------------------------------------------- Distribution Fee 0.25% 0.75% - -------------------------------------------------------------------------------- Service Fee 0.25% 0.25% - -------------------------------------------------------------------------------- The plans provide that the R Class will pay ACIS an annual distribution and service fee of 0.50%. The fees are computed and accrued daily based on each class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred in connection with distributing shares of the classes including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the funds. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers for Advisor Class shares and for individual shareholder services rendered by broker/dealers or other independent financial intermediaries for C Class and R Class shares. Fees incurred under the plans during the year ended October 31, 2006, are detailed in the Statement of Operations. (continued) - ------ 39 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. The funds have a bank line of credit agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the funds and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3.

BANK LINE OF CREDIT The funds, along with certain other funds managed by ACIM or ACGIM, have a $500 million unsecured bank line of credit agreement with JPMCB. The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The funds did not borrow from the line during the year ended October 31, 2006. 6. RISK FACTORS Focused Growth is considered nondiversified which may subject the fund to the following risks: a price change in one security may have a greater impact than would be the case if the fund were diversified; the fund's nondiversification could result in high portfolio turnover which could mean increased transaction costs, affecting both the fund's performance and capital gains tax liabilities to investors. 7. FEDERAL TAX INFORMATION The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 were as follows: - ---------------------------------------------------------------------------------- GROWTH FOCUSED GROWTH - ---------------------------------------------------------------------------------- 2006 2005 2006 2005(1) - ---------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - ---------------------------------------------------------------------------------- Ordinary income $21,518 $3,263 $94 -- - ---------------------------------------------------------------------------------- (1) February 28, 2005 (fund inception) through October 31, 2005. - ---------------------------------------------------------------------------------- HERITAGE VISTA - ---------------------------------------------------------------------------------- 2006 2005 2006 2005 - ---------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - ---------------------------------------------------------------------------------- Long-term capital gains $5,576 -- -- -- - ---------------------------------------------------------------------------------- The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements.

FEDERAL TAX INFORMATION (CONTINUED) As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - --------------------------------------------------------------------------------------------- GROWTH FOCUSED GROWTH HERITAGE VISTA - --------------------------------------------------------------------------------------------- Federal tax cost of investments $4,092,382 $14,597 $939,934 $1,936,164 ============================================================================================= Gross tax appreciation of investments $720,552 $1,278 $227,204 $388,352 - ---------------------------------------- Gross tax depreciation of investments (15,135) (99) (10,367) (7,387) - --------------------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $705,417 $1,179 $216,837 $380,965 ============================================================================================= Net tax appreciation (depreciation) of derivatives and translation of assets and liabilities in foreign currencies (60) 1 (3) -- - --------------------------------------------------------------------------------------------- Net tax appreciation (depreciation) $705,357 $1,180 $216,834 $380,965 ============================================================================================= Undistributed ordinary income $4,668 $312 -- -- - ---------------------------------------- Accumulated long-term gains -- -- $78,362 $18,229 - ---------------------------------------- Accumulated capital losses $(777,572) -- -- -- - --------------------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers expire in 2011 for Growth. 8. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. 9.

See Notes to Financial Statements. - ------ 60 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Growth Fund, Focused Growth Fund, Heritage Fund, and Vista Fund (collectively the "Funds"), four of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statements of operations for the year then ended, the statements of changes in net assets for the periods presented, and the financial highlights for the periods presented. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds, as of October 31, 2006, the results of their operations for the year then ended, the changes in their net assets for periods presented, and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Growth, Focused Growth, Heritage and Vista (the "funds") and the services provided to the funds under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the funds under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the funds and their shareholders on a routine and non-routine basis; * data comparing the cost of owning the funds to the cost of owning similar funds; * data comparing the funds' performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the funds to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the funds' board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of the advice of its independent counsel throughout the period. (continued) - ------ 65 Approval of Management Agreements for Growth, Focused Growth, Heritage, and Vista FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the funds. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the funds' portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the funds in accordance with their investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting, the Directors review investment performance information for the funds, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the funds. The Directors also review detailed performance information during the 15(c) Process comparing the funds' performance with that of similar funds not (continued) - ------ 66 Approval of Management Agreements for Growth, Focused Growth, Heritage, and Vista managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. Growth's performance fell below the median for both the one and three year periods during the past year. Heritage's performance for the one year period was in the highest quartile for its peer group and below the median for the three year period during part of the past year. Vista's performance for the one year period was below the median for its peer group and above the median for the three year period during part of the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the funds, its profitability in managing the funds, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its (continued) - ------ 67 Approval of Management Agreements for Growth, Focused Growth, Heritage, and Vista reinvestment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the funds specifically, the expenses incurred by the advisor in providing various functions to the funds, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the funds increase in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The funds pay the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the funds, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the funds' independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the funds and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the funds' unified fee to the total expense ratio of other funds in the funds' peer groups. The unified fee charged to shareholders of each of Growth and Focused Growth was below the median of the total expense ratios of its peer group. The unified fee charged to shareholders of each of Heritage and Vista was in the lowest quartile of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the funds. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the funds. The Directors analyzed this information and concluded that the fees charged and services provided to the funds were reasonable by comparison. (continued) - ------ 68 Approval of Management Agreements for Growth, Focused Growth, Heritage, and Vista COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the funds. They concluded that the advisor's primary business is managing mutual funds and it generally does not use the funds or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the funds, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the funds to determine breakpoints in the funds' fee schedules, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, in the absence of particular circumstances and assisted by the advice of legal counsel that is independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor concluded that the investment management agreement between each of Focused Growth, Heritage and Vista and the advisor is fair and reasonable in light of the services provided and should be renewed. The independent directors of Growth negotiated changes to the breakpoint schedule used to calculate Growth's management fee. These changes were proposed by the Directors based on their review of the competitive changes in the mutual fund marketplace and their review of financial information provided by the advisor. The new schedule, effective August 1, 2006, contains lower management fees at certain asset levels than under the existing structure. Following these negotiations with the advisor, the independent directors concluded that the investment management agreement between Growth and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 69 Share Class Information Five classes of shares are authorized for sale by Growth and Vista: Investor Class, Institutional Class, Advisor Class, C Class, and R Class. Focused Growth offers the Investor Class. Four classes of shares are authorized for sale by Heritage: Investor Class, Institutional Class, Advisor Class, and C Class. The total expense ratio of Institutional Class shares is lower than that of Investor Class shares. The total expense ratios of Advisor Class, C Class, and R Class shares are higher than that of Investor Class shares. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. ADVISOR CLASS shares are sold primarily through institutions such as investment advisors, banks, broker-dealers, insurance companies, and financial advisors. Advisor Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. The total expense ratio of Advisor Class shares is 0.25% higher than the total expense ratio of Investor Class shares. C CLASS shares are sold primarily through employer sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. C Class shares redeemed within 12 months of purchase are subject to a contingent deferred sales charge (CDSC) of 1.00%. There is no CDSC on shares acquired through reinvestment of dividends or capital gains. The unified management fee for C Class shares is the same as for Investor Class shares. C Class shares also are subject to a Rule 12b-1 distribution and service fee of 1.00%. R CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. The unified management fee for R Class shares is the same as for Investor Class shares. R Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. All classes of shares represent a pro rata interest in the funds and generally have the same rights and preferences. - ------ 70 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective [photo of Mark Mallon] Market Perspective BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

As outlined in the Market Perspective on page 2, a pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. An overweight position in the wireless telecommunication industry and well-timed sector position shifts in industrials and information technology helped the portfolio outperform the Russell Midcap Growth Index. Relatively weaker returns in the health care and financials sectors reduced relative performance. INVESTMENT PROCESS PAID OFF For the second straight fiscal year, we reaped our biggest relative and absolute gains from an overweight stake in the wireless telecommunications industry. The portfolio's investments in that industry, centered on two cellular providers in the Latin American market, composed a significant share of the portfolio's total return in the 12-month period. Meanwhile, our focus on companies with accelerating financial growth and share price momentum helped us adjust our weighting of two key at opportune times. We raised our stake in the industrials sector in the first half of the period, when rising commodity prices and capital investment boosted stocks in that sector. Later, in accordance with our investment process, we reduced our industrials exposure in the second half of the period, when the sector lost steam as the economy slowed. Likewise, we reduced our stake in information technology early in the reporting period, when the sector was out of favor. But as growth and technology shares gained favor late in the period, we increased our exposure to the sector. For the full 12-month period, our underweight position in technology benefited the portfolio. WIRELESS STOCKS LED PERFORMANCE The portfolio's five biggest overweight stocks also ranked as its top five contributors.

They also finished first and second on the portfolio's list of top contributors, with NII's shares gaining 57% and America Movil's rising 68%. In addition to the cellular investments, top contributors included a stake in Aker Kvaerner ASA, a Norway-based maker of processing equipment for oil and gas companies. Precision Castparts, a manufacturer of metal components for aerospace and industrial applications, was another top contributor. Precision benefited from a rebound in aircraft industry orders. HEALTH CARE INFECTED RETURNS Five of the portfolio's 10 worst relative performers resided in the health care sector, where we maintained a detrimental overweight position. Prescription manager Caremark and managed care provider Aetna topped the list of the sector's leading detractors. Shares in both declined as the entire health care services industry battled concerns about tightening profit margins and slowing increases in managed care premiums. An underweight stake in financials, combined with weak security selection in that sector, also reduced relative returns. Most of the sector benefited from relatively stable long-term interest rates, expectations of declining short-term interest rates sometime in 2007, and sound market returns that bolstered interest in capital markets. PORTFOLIO OBJECTIVE & EXPECTATIONS Giftrust is an irrevocable trust designed to be given as a gift to those seeking long-term growth who can tolerate high share price fluctuation; it must be held for at least 18 years. Our process focuses on medium-sized and smaller companies with accelerating earnings growth rates and share price momentum. We believe that active investing in such companies will generate outperformance over time compared with the Russell Midcap Growth Index.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical (continued) - ------ 7 Shareholder Fee Example (Unaudited) example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - ----------------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - ----------------------------------------------------------------------------------------- GIFTRUST SHAREHOLDER FEE EXAMPLE - ----------------------------------------------------------------------------------------- Actual $1,000 $938.50 $4.89 1.00% - ----------------------------------------------------------------------------------------- Hypothetical $1,000 $1,020.16 $5.09 1.00% - ----------------------------------------------------------------------------------------- * Expenses are equal to the fund's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 8 Giftrust - Schedule of Investments OCTOBER 31, 2006 Shares ($ IN THOUSANDS) Value - -------------------------------------------------------------------------------- COMMON STOCKS -- 99.7% AEROSPACE & DEFENSE -- 8.9% - -------------------------------------------------------------------------------- 1,079,393 BE Aerospace, Inc.(1) $ 27,287 - -------------------------------------------------------------------------------- 62,200 Boeing Co. 4,967 - -------------------------------------------------------------------------------- 819,200 Precision Castparts Corp. 55,755 - -------------------------------------------------------------------------------- 88,009 - -------------------------------------------------------------------------------- AIR FREIGHT & LOGISTICS -- 0.2% - -------------------------------------------------------------------------------- 61,697 UTI Worldwide Inc. 1,595 - -------------------------------------------------------------------------------- BEVERAGES -- 0.2% - -------------------------------------------------------------------------------- 118,900 C&C Group plc ORD 1,977 - -------------------------------------------------------------------------------- BIOTECHNOLOGY -- 4.0% - -------------------------------------------------------------------------------- 202,799 CSL Ltd.

------ 14 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Giftrust Fund (the fund) is one fund in a series issued by the corporation. The fund is diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth. The fund pursues its objective by investing primarily in equity securities of medium- and small-sized companies. The following is a summary of the fund's significant accounting policies. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. SECURITIES ON LOAN -- The fund may lend portfolio securities through its lending agent to certain approved borrowers in order to earn additional income. The fund continues to recognize any gain or loss in the market price of the securities loaned and records any interest earned or dividends declared. FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The fund records the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The fund may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the fund's exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the fund and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The fund bears the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by (continued) - ------ 15 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee). The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of the fund and paid monthly in arrears. The annual management fee for the fund is 1.00%. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, American Century Investment Services, Inc., and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement and securities lending agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of J.P. Morgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchase and sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, were $2,283,153 and $2,383,387, respectively. (continued) - ------ 16 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 4. SECURITIES LENDING As of October 31, 2006, the fund had no securities on loan. In the case of securities lending transactions, JPMCB receives and maintains collateral in the form of cash, and/or acceptable securities as approved by ACIM. Cash collateral is invested in authorized investments by the lending agent in a pooled account. Any deficiencies or excess of collateral must be delivered or transferred by the member firms no later than the close of business on the next business day. The fund's risks in securities lending are that the borrower may not provide additional collateral when required or return the securities when due. If the borrower defaults, receipt of the collateral by the fund may be delayed or limited. 5. BANK LINE OF CREDIT The fund, along with certain other funds managed by ACIM or ACGIM, has a $500 million unsecured bank line of credit agreement with JPMCB. The fund may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund did not borrow from the line during the year ended October 31, 2006. 6. FEDERAL TAX INFORMATION The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. There were no distributions paid by the fund during the years ended October 31, 2006 and October 31, 2005. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: Federal tax cost of investments $825,869 ================================================================================ Gross tax appreciation of investments $176,570 - ------------------------------------------------------ Gross tax depreciation of investments (14,057) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $162,513 ================================================================================ Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies (7) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $162,506 ================================================================================ Undistributed ordinary income -- - ------------------------------------------------------ Accumulated capital losses $(261,041) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on certain forward foreign currency exchange contracts. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers expire as follows: - -------------------------------------------------------------------------------- 2009 2010 2011 - -------------------------------------------------------------------------------- $(116,339) $(138,462) $(6,240) - -------------------------------------------------------------------------------- (continued) - ------ 17 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 7. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. - ------ 18 Giftrust - Financial Highlights For a Share Outstanding Throughout the Years Ended October 31 - --------------------------------------------------------------------------------------------------- 2006 2005 2004 2003 2002 - --------------------------------------------------------------------------------------------------- PER-SHARE DATA - --------------------------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $17.28 $13.81 $14.04 $11.88 $14.04 - --------------------------------------------------------------------------------------------------- Income From Investment Operations - ------------------------------------------ Net Investment Income (Loss) (0.05) (0.08) (0.01)(1) (0.07)(1) (0.06)(1) - ------------------------------------------ Net Realized and Unrealized Gain (Loss) 2.90 3.55 (0.22) 2.23 (2.10) - --------------------------------------------------------------------------------------------------- Total From Investment Operations 2.85 3.47 (0.23) 2.16 (2.16) - --------------------------------------------------------------------------------------------------- Net Asset Value, End of Period $20.13 $17.28 $13.81 $14.04 $11.88 =================================================================================================== TOTAL RETURN(2) 16.49% 25.13% (1.64)% 18.18% (15.38)% RATIOS/SUPPLEMENTAL DATA - --------------------------------------------------------------------------------------------------- Ratio of Operating Expenses to Average Net Assets 1.00% 1.00% 0.49%(3) 1.00% 1.00% - ------------------------------------------ Ratio of Net Investment Income (Loss) to Average Net Assets (0.22)% (0.46)% (0.09)%(3) (0.55)% (0.42)% - ------------------------------------------ Portfolio Turnover Rate 229% 223% 260% 140% 140% - ------------------------------------------ Net Assets, End of Period (in millions) $985 $927 $865 $896 $756 - --------------------------------------------------------------------------------------------------- (1) Computed using average shares outstanding throughout the period.

See Notes to Financial Statements. - ------ 19 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Giftrust Fund, (the "Fund"), one of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Giftrust Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Giftrust (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of the advice of its independent counsel throughout the period. (continued) - ------ 24 Approval of Management Agreement for Giftrust FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. Nature, Extent and Quality of Services - Generally. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the fund. The Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not (continued) - ------ 25 Approval of Management Agreement for Giftrust managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance for the one year period was in the highest quartile for its peer group and below the median for the three year period during part of the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvestment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other (continued) - ------ 26 Approval of Management Agreement for Giftrust information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was in the lowest quartile of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or (continued) - ------ 27 Approval of Management Agreement for Giftrust shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, in the absence of particular circumstances and assisted by the advice of legal counsel that is independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 28 Additional Information INDEX DEFINITIONS The following indices are used to illustrate investment market, sector, or style performance or to serve as fund performance comparisons.

Market Perspective [photo of Chief Investment Officer] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

We'll discuss why Select didn't match those returns and what we're doing to address that issue. INVESTMENT PROCESS ENHANCEMENTS Harold Bradley joined the Select team as co-portfolio manager in April 2006. With his arrival, and as part of our ongoing effort to improve performance, we have enhanced the portfolio's investment process with a multi-factor model that we believe can better identify stocks with price momentum and improving fundamentals. The portfolio retains its bias toward high-quality stocks and stocks that have attractive risk/reward characteristics within the large-cap growth space. But the multi-factor model now employs a more systematic and rigorous screening process that takes into account factors such as earnings quality and relative valuation levels. CHALLENGING MARKET FACTORS The portfolio's relative underperformance for the entire reporting period resulted from an overweight in health care and consumer staples stocks, in addition to security selection in each of those sectors. Underweight stakes and security selection in energy and financials further contributed to relative underperformance. On a total return basis, the portfolio received solid gains from stakes in technology and consumer discretionary stocks, but not enough to offset losses in energy and health care. In addition, shifting market conditions caused the application of our process enhancements to detract from performance. Select suffered in the first half of the reporting period from underweight stakes in non-traditional growth sectors such as energy and materials. Our process enhancements took effect in spring 2006, refocusing the portfolio on large-cap stocks exhibiting classic price momentum and growth characteristics. However, the market shortly thereafter steered away from the type of stocks we prefer, further damaging the portfolio's performance.

(continued) - ------ 5 Select - Portfolio Commentary Harold Bradley described what happened in the summer of 2006: "The market pummeled growth and pummeled momentum. If you were looking for a harsh environment for what we do in this fund, this was the harshest environment possible." ENERGY, HEALTH CARE LED DETRACTORS Energy and health care accounted for four of Select's 10 biggest relative detractors in the reporting period. Shares in the portfolio's worst performer, coal mine operator Peabody Energy Corp., followed crude oil and natural gas prices lower throughout the summer. Coal competes with natural gas as an energy source for power plants, among other uses. As a result, it becomes less attractive for energy users when natural gas prices dip. We sold our position in Peabody. Select's health care losses spread across various industries in the sector. Shares of the portfolio's worst individual performer in the sector, medical equipment maker Hospira, plunged in early August after its second-quarter earnings report missed consensus market forecasts. LARGEST HOLDING LED TOP PERFORMERS Select's top average overweight holding, International Game Technology, also topped the portfolio's list of best performers in the period. Shares in the slot-machine maker surged 63% as global demand for gaming machines continued expanding. Another substantial overweight position in the gaming sector, a stake in Las Vegas Sands Corp., also ranked among the portfolio's leading stocks. The company's shares more than doubled in value during the period as its new casino in Macau produced strong earnings growth. PORTFOLIO OBJECTIVE & EXPECTATIONS Select seeks long-term growth and is designed as a core holding for a diversified portfolio. We seek large, established companies with attractive risk/reward characteristics. Within that framework, we specifically desire companies that have accelerating growth in earnings and revenue and appear capable of sustaining such growth over time. We believe that owning such companies will generate outperformance over time compared with the S&P 500.

On an absolute basis, every stock sector contributed to Capital Growth's return except utilities, a tiny portion (less than 1%) of the fund and the index. Relative to its benchmark, Capital Growth's outperformance resulted largely from effective stock selection across a wide range of sectors, including information technology, industrials, and energy, among others. Indeed, the portfolio's positions outperformed in all but two of the index's sectors -- financial stocks and utilities. INFORMATION TECHNOLOGY LED OUTPERFORMANCE Information technology stocks were the leading source of the portfolio's outperformance during the fiscal year. Stock selection in semiconductors contributed significantly, especially an overweight in Freescale Semiconductor, a spin-off from Motorola producing chips for a number of wireless and industrial applications. Freescale performed well overall, and received an additional boost near the end of the period after agreeing to be acquired at a significant premium to its existing share price. Coupled with an underweight to Intel, which performed poorly, these were two of the top-three contributors to relative returns. Capital Growth also benefited from good stock selection in industrials. For the year, the industrial names in the portfolio were up 19% during the period, compared with 15% for those in the index. Stock selection also had a positive effect in the energy sector, where performance was quite volatile quarter-to-quarter. In general, we avoided firms with exposure to the volatile North TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF % OF NET ASSETS NET ASSETS AS OF AS OF 10/31/06 4/30/06 - -------------------------------------------------------------------------------- Bank of America Corp. 3.3% -- - -------------------------------------------------------------------------------- Cisco Systems Inc. 3.0% 3.1% - -------------------------------------------------------------------------------- Intel Corp. 2.8% -- - -------------------------------------------------------------------------------- PepsiCo, Inc. 2.6% 2.9% - -------------------------------------------------------------------------------- Oracle Corp. 2.6% 1.0% - -------------------------------------------------------------------------------- Google Inc.

(continued) - ------ 12 Capital Growth - Portfolio Commentary American natural gas market; instead, we favored service companies more closely tied to oil companies with well-financed capital expenditure budgets. As a result, Capital Growth's energy holdings were up 20%, compared with 8% for this segment of the index. The portfolio's top contributor in this space was Schlumberger, a global oil-field-services provider benefiting from increased exploration for oil and gas given higher energy prices overall. That helped Schlumberger return 40% for the 12-month period. Finally, our top contributor for the 12 months was an overweight position in Archer Daniels Midland (ADM), which performed well on the strength of its oilseed and corn processing businesses. ADM drew additional investor interest during the period because it is a leading producer of ethanol, an alternative and additive to gasoline made from corn. FINANCIALS DETRACTED The portfolio's performance would have been even better relative to its benchmark but for positioning among financials shares. For the year, Capital Growth's financial holdings were up 14%, compared with 18% for this portion of the index. Despite an overweight position in this sector, which was among the best-performing segments of the market for the year, disappointing stock selection limited Capital Growth's relative return. In particular, positioning among capital markets shares -- the leading contributor to index returns from the financials sector -- detracted from relative performance. PORTFOLIO OBJECTIVE & EXPECTATIONS Capital Growth seeks long-term capital appreciation. We pursue our objective by continuing to remain fully invested in large companies that are exhibiting sustainable improvement in their businesses. It is our belief that owning such companies will generate outperformance over time versus the Russell 1000 Growth Index and the other funds in our large-growth peer group.

The portfolio's return ranked in the third percentile of its Morningstar Large-Cap Blend category (37th out of 1,932 funds).** As outlined in the Market Perspective on page 2, a pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period. Fundamental Equity enjoyed positive total returns from all but one market sector in the reporting period, as we successfully maneuvered the market's broad transition away from industrials and materials stocks to technology and consumer discretionary stocks beginning in May 2006. The portfolio's relative return also benefited from our efforts to avoid weak internet stocks and remain in an underweight position in the struggling home building industry. That helped overcome detrimental relative results in telecommunications -- the only sector that didn't contribute to the portfolio's absolute return -- and financials. The latest fiscal-year performance bolstered Fundamental Equity's longer-term track record. Since its November 30, 2004, inception, the portfolio has returned an annual average of 15.80%, exceeding the benchmark's annual return of 10.73% in the same time frame. OUR BIG STAKES WORKED Our stakes in industrials and materials -- along with an advantageous underweight position in utilities -- contributed the lion's share of the portfolio's outperformance. The first two of those sectors performed particularly well as the economy surged in the first half of the reporting period. Shares in the portfolio's leading individual relative performer, H&E Equipment Services, rose 57% in the three months after its early February initial public offering. As with many other industrial stocks, though, shares in the distributor of heavy construction equipment fell as the market sold off in May 2006. But we avoided the stock's downturn by selling our stake beforehand.

(continued) - ------ 19 Fundamental Equity - Portfolio Commentary Fundamental Equity's biggest individual overweight position, a stake in technology consulting firm Accenture, also ranked among its best performers. The company benefited as the market favored technology stocks late in the reporting period. In addition, a position in Merck also benefited the portfolio. Part of the portfolio's process involves finding underappreciated stocks, and we suspected investors may have punished the company's stock too much in late 2005 and early 2006 for its Vioxx-related lawsuits. In mid-July, Merck successfully defended a Vioxx suit, its fourth victory in seven such cases. The company's shares rose 24% between the date of that verdict and the end of the reporting period. MISSED CALLS IN TELECOM We applied the bulk of our underweight stake in the telecommunications sector to wireless providers. As a result, the portfolio suffered on a relative basis from a limited exposure to diversified providers, whose 46% total return within the benchmark ranked second among all market industries. We totally avoided investments in AT&T and BellSouth, which both rallied after the former agreed to buy the latter. Our focus on areas of the market we perceive as undervalued led us early in the period to the financials sector, which had experienced somewhat sluggish returns in 2005 as the Federal Reserve continued raising interest rates. Financials accounted for almost a fifth of our total holdings, and no other sector contributed more to the portfolio's total return. But a slight underweight stake in the sector and unfavorable security selection within it trimmed relative results. PORTFOLIO OBJECTIVES & EXPECTATIONS We manage Fundamental Equity as a large-cap core portfolio that seeks capital growth and current income. We target investments in large companies we perceive as attractively valued relative to their prospects for earnings growth and income production. Our focus on bellwether large-cap stocks should put the portfolio in position for solid returns in 2007 if the market's shift toward large-caps in the last six months of the reporting period persists.

As outlined in the Market Perspective on page 2, a pause in the Federal Reserve's interest rate hikes and expectations for lower interest rates and mild inflation going forward helped New Opportunities II post its highest fiscal-year return since 2003. Small-cap stocks outpaced large-cap stocks for the period, particularly in the first six months. The portfolio outperformed its benchmark during that time, as the directional trend in the market suited the portfolio's focus on share-price momentum and earnings growth acceleration. In the second half of the period, though, the performance of large-cap stocks improved as economic growth slowed. Small-caps lagged, with the Russell 2000 Index falling 10.27% between May 1 and July 15. The portfolio struggled to adjust to this quick transition, especially as growth and momentum factors that fit our investment style fell out of favor late in the period. The June-September time period was the most adverse for growth and momentum investment factors in 11 quarters. The fund typically does not generate excess returns during market cycles when growth and momentum factors rotate out of favor. Also, stock selection in the health care and technology sectors hurt relative performance. Despite its recent challenges, the portfolio ranked in the 19th percentile of its Morningstar category (81st out of 529 funds)** in the five-year period ended October 31, 2006. In that five-year period, the portfolio returned an annual average of 12.29%, compared with 9.51% for its benchmark. MANAGEMENT CHANGES In April 2006, Stafford Southwick, formerly an investment analyst on the New Opportunities II team, was named co-portfolio manager of the fund. On June 30, 2006, portfolio manager Tom Telford switched responsibilities, leaving New Opportunities II to co-manage another American Century mutual fund.

(continued) - ------ 26 New Opportunities II - Portfolio Commentary Opportunities II, succeeded Telford as co-manager of the portfolio. MATERIALS ROLLED New Opportunities II took advantage of an upward trend in the materials sector early in the 12-month period, as that sector surged with commodity prices. For the full period, both an overweight position and sound security selection in that sector boosted the portfolio's relative performance considerably. The materials sector contained the portfolio's largest average overweight position in the reporting period, Titanium Metals. For the second consecutive fiscal year, this maker of lightweight titanium materials for the aircraft industry topped the portfolio's list of leading individual stock performers, as its shares surged 149%. Two other companies in the sector, Zoltek and OM Group, also ranked among the portfolio's top five relative contributors. TROUBLE IN HEALTH CARE, TECHNOLOGY The bulk of New Opportunities II's relative underperformance stemmed from our stock choices in health care and technology, including the portfolio's leading detractor, Quidel Corp. Quidel makes diagnostic test kits, including one for detecting the flu. Its share price plunged in late 2005, and we sold our stake in the company. The portfolio also suffered from security selection in the industrials sector, primarily from a stake in GrafTech International, an Ohio-based maker of fuel cells. The company lost more than a third of its market value in one trading session in early February 2006, a month before it reported a significant decline in its fourth-quarter 2005 operating profit. PORTFOLIO OBJECTIVE & EXPECTATIONS New Opportunities II seeks long-term growth and is designed to provide small-cap exposure to a diversified investment portfolio. The portfolio is best suited for investors who can tolerate high levels of share price fluctuation in exchange for compelling long-term return potential. To achieve our objective, we pursue an investment approach of 1) identifying small companies that appear to have accelerating earnings and revenue growth and 2) buying those companies when potential rewards appear greatest.

See Notes to Financial Statements. - ------ 30 Shareholder Fee Examples (Unaudited) Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 31 Shareholder Fee Examples (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 -- EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - -------------------------------------------------------------------------------- SELECT SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- ACTUAL - -------------------------------------------------------------------------------- Investor Class $1,000 $964.80 $4.95 1.00% - -------------------------------------------------------------------------------- Institutional Class $1,000 $965.90 $3.96 0.80% - -------------------------------------------------------------------------------- Advisor Class $1,000 $963.90 $6.19 1.25% - -------------------------------------------------------------------------------- A Class $1,000 $963.60 $6.19 1.25% - -------------------------------------------------------------------------------- B Class $1,000 $960.20 $9.88 2.00% - -------------------------------------------------------------------------------- C Class $1,000 $960.20 $9.88 2.00% - -------------------------------------------------------------------------------- R Class $1,000 $962.60 $7.42 1.50% - -------------------------------------------------------------------------------- HYPOTHETICAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,020.16 $5.09 1.00% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,021.17 $4.08 0.80% - -------------------------------------------------------------------------------- Advisor Class $1,000 $1,018.90 $6.36 1.25% - -------------------------------------------------------------------------------- A Class $1,000 $1,018.90 $6.36 1.25% - -------------------------------------------------------------------------------- B Class $1,000 $1,015.12 $10.16 2.00% - -------------------------------------------------------------------------------- C Class $1,000 $1,015.12 $10.16 2.00% - -------------------------------------------------------------------------------- R Class $1,000 $1,017.64 $7.63 1.50% - -------------------------------------------------------------------------------- *Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period.

See Notes to Financial Statements. - ------ 39 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Select Fund (Select), Capital Growth Fund (Capital Growth), Fundamental Equity Fund (Fundamental Equity) and New Opportunities II Fund (New Opportunities II) (collectively, the funds) are four funds in a series issued by the corporation. The funds are diversified under the 1940 Act. The funds' investment objective is to seek long-term capital growth. Income is a secondary objective of Fundamental Equity. Select and Capital Growth pursue this objective by purchasing stocks of larger-sized companies that they believe will increase in value over time. Fundamental Equity looks for common stocks that the fund's managers believe are attractively priced relative to the companies' earnings growth potential and dividend yields. New Opportunities II pursues its objective by purchasing stocks of smaller-sized companies that it believes will increase in value over time. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- Select is authorized to issue the Investor Class, the Institutional Class, the Advisor Class, the A Class, the B Class, the C Class and the R Class. Capital Growth and Fundamental Equity are authorized to issue the Investor Class, the Institutional Class, the A Class, the B Class, the C Class and the R Class. New Opportunities II is authorized to issue the Investor Class, the Institutional Class, the A Class, the B Class and the C Class. The A Class may incur an initial sales charge. The A Class, B Class and C Class may be subject to a contingent deferred sales charge. The share classes differ principally in their respective sales charges and distribution and shareholder servicing expenses and arrangements. All shares of each fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the funds are allocated to each class of shares based on their relative net assets. Sale of Fundamental Equity's A Class, B Class and C Class commenced on November 30, 2004. Sale of Fundamental Equity's and Capital Growth's Investor Class, Institutional Class and R Class commenced on July 29, 2005. Sale of Select's R Class commenced on July 29, 2005. Sale of New Opportunities II's Institutional Class had not commenced as of October 31, 2006. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the funds determine that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day: or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The funds estimate the components of distributions received that may be considered nontaxable distributions or capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. (continued) - ------ 40 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) SECURITIES ON LOAN -- Select may lend portfolio securities through their lending agent to certain approved borrowers in order to earn additional income. Select continues to recognize any gain or loss in the market price of the securities loaned and record any interest earned or dividends declared. FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. Realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The funds record the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The funds may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the funds' exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the funds and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The funds bear the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. Each fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable each fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to each fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, each fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the funds. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. (continued) - ------ 41 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the funds, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of each specific class of shares of each fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in each fund's investment strategy (strategy assets) to calculate the appropriate fee rate for each fund. The strategy assets include each fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The annual management fee schedule for each class of Select, Capital Growth and Fundamental Equity, as applicable, is as follows: - -------------------------------------------------------------------------------- INVESTOR, A, B, C & R INSTITUTIONAL ADVISOR - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $5 billion 1.000% 0.800% 0.750% - -------------------------------------------------------------------------------- Next $5 billion 0.980% 0.780% 0.730% - -------------------------------------------------------------------------------- Next $5 billion 0.970% 0.770% 0.720% - -------------------------------------------------------------------------------- Next $5 billion 0.960% 0.760% 0.710% - -------------------------------------------------------------------------------- Next $5 billion 0.950% 0.750% 0.700% - -------------------------------------------------------------------------------- Next $5 billion 0.900% 0.700% 0.650% - -------------------------------------------------------------------------------- Over $30 billion 0.800% 0.600% 0.550% - -------------------------------------------------------------------------------- The annual management fee schedule for each class of New Opportunities II is as follows: - -------------------------------------------------------------------------------- INVESTOR, A, B, C & R INSTITUTIONAL - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $250 million 1.50% 1.30% - -------------------------------------------------------------------------------- Next $250 million 1.25% 1.05% - -------------------------------------------------------------------------------- Next $250 million 1.15% 0.95% - -------------------------------------------------------------------------------- Over $750 million 1.10% 0.90% - -------------------------------------------------------------------------------- The effective annual management fee for each class of each fund for the year ended October 31, 2006 was as follows: - -------------------------------------------------------------------------------- INVESTOR, A, B, C & R INSTITUTIONAL ADVISOR R - -------------------------------------------------------------------------------- Select 1.00% 0.80% 0.75% 1.00% - -------------------------------------------------------------------------------- Capital Growth 1.00% 0.80% N/A 1.00% - -------------------------------------------------------------------------------- Fundamental Equity 1.00% 0.80% N/A 1.00% - -------------------------------------------------------------------------------- New Opportunities II 1.50% -- N/A N/A - -------------------------------------------------------------------------------- (continued) - ------ 42 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master Distribution and Shareholder Services Plan for the Advisor Class (the Advisor Class plan) and a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class, B Class, C Class and R Class (collectively with the Advisor Class plan, the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the Advisor Class, B Class and C Class will pay American Century Investment Services, Inc. (ACIS) the following annual distribution and service fees: - -------------------------------------------- ADVISOR B & C - -------------------------------------------- Distribution Fee 0.25% 0.75% - -------------------------------------------- Service Fee 0.25% 0.25% - -------------------------------------------- The plans provide that the A Class and the R Class will pay ACIS an annual distribution and service fee of 0.25% for the A Class and 0.50% for the R Class. The fees are computed and accrued daily based on each class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred in connection with distributing shares of the classes including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the funds. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers for Advisor Class shares and for individual shareholder services rendered by broker/dealers or other independent financial intermediaries for A Class, B Class, C Class and R Class shares. Fees incurred under the plans during the year ended October 31, 2006, are detailed in the Statement of Operations. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. As of October 31, 2006 the outstanding shares owned by the investment advisor of Capital Growth is 31%. The funds have a bank line of credit agreement and Select has a securities lending agreement with JPMorgan Chase Bank (JPMCB).

SECURITIES LENDING As of October 31, 2006, securities in Select valued at $202,251,274, were on loan through the lending agent, JPMCB, to certain approved borrowers. JPMCB receives and maintains collateral in the form of cash, and/or acceptable securities as approved by ACIM. Cash collateral is invested in authorized investments by the lending agent in a pooled account. The value of cash collateral received at period end is disclosed in the Statement of Assets and Liabilities and investments made with the cash by the lending agent are listed in the Schedule of Investments. Any deficiencies or excess of collateral must be delivered or transferred by the member firms no later than the close of business on the next business day. The total value of all collateral received, at this date, was $205,067,793. Select's risks in securities lending are that the borrower may not provide additional collateral when required or return the securities when due. If the borrower defaults, receipt of the collateral by Select may be delayed or limited. 6. BANK LINE OF CREDIT The funds, along with certain other funds managed by ACIM or ACGIM, have a $500,000,000 unsecured bank line of credit agreement with JPMCB. The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The funds did not borrow from the line during the year ended October 31, 2006. (continued) - ------ 48 Notes to Financial Statements OCTOBER 31, 2006 7. RISK FACTORS New Opportunities II concentrates its investments in common stocks of small companies. Because of this, New Opportunities II may be subject to greater risk and market fluctuations than a fund investing in larger, more established companies. 8. FEDERAL TAX INFORMATION The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 were as follows: - -------------------------------------------------------------------------------- SELECT CAPITAL GROWTH - -------------------------------------------------------------------------------- 2006 2005 2006 2005 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - -------------------------------------------------------------------------------- Ordinary income $25,309,867 $9,128,831 -- -- - -------------------------------------------------------------------------------- Long-term capital gains -- -- -- -- - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- FUNDAMENTAL EQUITY NEW OPPORTUNITIES II - -------------------------------------------------------------------------------- 2006 2005(1) 2006 2005 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - -------------------------------------------------------------------------------- Ordinary income $120,479 -- $1,381,083 $995,034 - -------------------------------------------------------------------------------- Long-term capital gains -- -- $1,602,464 $785,251 - -------------------------------------------------------------------------------- (1) November 30, 2004 (fund inception) through October 31, 2005. The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------------- CAPITAL FUNDAMENTAL NEW SELECT GROWTH EQUITY OPPORTUNITIES II - -------------------------------------------------------------------------------------- Federal tax cost of investments $2,782,626,469 $3,650,765 $45,827,612 $122,181,241 ====================================================================================== Gross tax appreciation of investments $227,643,417 $433,949 $3,283,324 $15,766,059 - ------------------------ Gross tax depreciation of investments (43,350,063) (12,010) (294,301) (668,558) - -------------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $184,293,354 $421,939 $2,989,023 $15,097,501 ====================================================================================== Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies $(2,390) $(71) -- -- - -------------------------------------------------------------------------------------- Net tax appreciation (depreciation) $184,290,964 $421,868 $2,989,023 $15,097,501 ====================================================================================== Undistributed ordinary income $11,973,143 -- $871,053 $2,458,338 - ------------------------ Accumulated long-term gains $42,881,708 $51,137 $ 19,286 $9,474,334 - -------------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on certain forward foreign currency contracts and return of capital dividends. (continued) - ------ 49 Notes to Financial Statements OCTOBER 31, 2006 9. REORGANIZATION PLAN On December 14, 2005, the Board of Directors of Mason Street Growth Stock Fund (Growth Stock), one fund in a series issued by Mason Street Funds, Inc., approved a plan of reorganization (the reorganization) pursuant to which Select acquired all of the assets of Growth Stock in exchange for shares of equal value of Select and the assumption by Select of all liabilities of Growth Stock. The financial statements and performance history of Select will be carried over in the post-reorganization. The reorganization was approved by shareholders on March 23, 2006. The reorganization was effective at the close of business on March 31, 2006. New shares in connection with the reorganization were issued by Select on April 3, 2006. The acquisition was accomplished by a tax-free exchange of shares. On April 3, 2006, Growth Stock exchanged its shares for shares of Select as follows: - -------------------------------------------------------------------------------- ORIGINAL FUND/CLASS SHARES EXCHANGED NEW FUND/CLASS SHARES RECEIVED - -------------------------------------------------------------------------------- Growth Stock Fund - A 9,879,722 Select - A Class 3,564,222 - -------------------------------------------------------------------------------- Growth Stock Fund - C 17,465 Select - A Class 6,020 - -------------------------------------------------------------------------------- Growth Stock Fund - B 443,869 Select - B Class 155,909 - -------------------------------------------------------------------------------- The net assets of Growth Stock and Select immediately before the acquisition were $141,155,681 and $3,336,122,073, respectively. Growth Stock's unrealized appreciation of $26,507,502 was combined with that of Select. Immediately after the acquisition, the combined net assets were $3,477,277,754. 10. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. (continued) - ------ 50 Notes to Financial Statements OCTOBER 31, 2006 11.

See Notes to Financial Statements. - ------ 74 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Select Fund, Capital Growth Fund, Fundamental Equity Fund and New Opportunities II Fund, (collectively the "Funds"), four of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statements of operations for the year then ended, the statements of changes in net assets for the periods presented, and the financial highlights for the periods presented. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds as of October 31, 2006, the results of their operations for the year then ended, the changes in their net assets for periods presented, and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Select, Capital Growth, Fundamental Equity and New Opportunities II (the "funds") and the services provided to the funds under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the funds under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the funds and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the funds to the cost of owning similar funds; * data comparing the funds' performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the funds to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the funds' board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of the advice of its independent counsel throughout the period. (continued) - ------ 80 Approval of Management Agreements for Select, Capital Growth, Fundamental Equity and New Opportunities II FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the funds. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the funds' portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the funds in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the funds, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the funds. The Directors also review detailed performance information (continued) - ------ 81 Approval of Management Agreements for Select, Capital Growth, Fundamental Equity and New Opportunities II during the 15(c) Process comparing the funds' performance with that of similar funds not managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. Select's, Capital Growth's and New Opportunities II's performance fell below the median for both the one and three year periods during the past year. The board discussed the funds' performance with the advisor and was satisfied with the efforts being undertaken by the advisor. Fundamental Equity's performance for both the one and three year periods was above the median for its peer group. SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the funds, its profitability in managing the funds, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvestment in its (continued) - ------ 82 Approval of Management Agreements for Select, Capital Growth, Fundamental Equity and New Opportunities II ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the funds specifically, the expenses incurred by the advisor in providing various functions to the funds, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the funds increase in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The funds pay the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the funds, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the funds' independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the funds and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the funds' unified fee to the total expense ratio of other funds in the funds' peer group. The unified fee charged to shareholders of each of Select and Capital Growth was below the median of the total expense ratios of its peer group. The unified fee charged to shareholders of Fundamental Equity was near the median of the total expense ratios of its peer group. The unified fee charged to shareholders of New Opportunity II was above the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the funds. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the funds. The Directors analyzed this information and concluded that the fees charged and services provided to the funds were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed infor- (continued) - ------ 83 Approval of Management Agreements for Select, Capital Growth, Fundamental Equity and New Opportunities II mation from the advisor concerning collateral benefits it receives as a result of its relationship with the funds. They concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the funds, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the funds to determine breakpoints in the funds' fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, assisted by the advice of legal counsel independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor, negotiated changes to the breakpoint schedule used to calculate the fund's management fee. These changes were proposed by the Directors based on their review of the competitive changes in the mutual fund marketplace and their review of financial information provided by the advisor. The new schedule, effective August 1, 2006, contains lower management fees at certain asset levels than under the existing structure. Following these negotiations with the advisor, the independent directors concluded that the investment management agreement between the funds and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 84 Share Class Information Seven classes of shares are authorized for sale by Select: Investor Class, Institutional Class, Advisor Class, A Class, B Class, C Class and R Class.

Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective [photo of Mark Mallon] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

As outlined in the Market Perspective on page 2, a pause in the Federal Reserve's interest rate hikes and expectations for lower interest rates and mild inflation going forward helped New Opportunities post its highest fiscal-year return since 2003. Small-cap stocks outpaced large-cap stocks for the period, particularly in the first six months. The portfolio outperformed its benchmark during that time, as the directional trend in the market suited the portfolio's focus on share-price momentum and earnings growth acceleration. In the second half of the period, though, the performance of large-cap stocks improved as economic growth slowed. Small-caps lagged, with the Russell 2000 Index falling 10.27% between May 1 and July 15. The portfolio struggled to adjust to this quick transition, especially as growth and momentum factors that fit our investment style fell out of favor late in the period. The June-September time period was the most adverse for growth and momentum investment factors in 11 quarters. The fund typically does not generate excess returns during market cycles when growth and momentum factors rotate out of favor. Also, stock selection in the health care and technology sectors hurt relative performance. Despite its recent underperformance, New Opportunities has returned an annual average of 7.72% since its December 26, 1996, inception, compared with 4.74% for its benchmark*. MANAGEMENT CHANGES In April 2006, Stafford Southwick, formerly an investment analyst on the New Opportunities team, was named co-portfolio manager of the fund. On June 30, 2006, portfolio manager Tom Telford switched responsibilities, leaving New Opportunities to co-manage another American Century mutual fund. Matt Ferretti, a four-year American Century veteran and investment analyst for New Opportunities, succeeded Telford as co-manager of the portfolio. MATERIALS ROLLED New Opportunities took advantage of an upward trend in the materials sector early in the 12-month period, as that sector surged with commodity prices. For the full period, both an overweight TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - ------------------------------------------------------------------------------- % OF % OF NET ASSETS NET ASSETS AS OF AS OF 10/31/06 4/30/06 - -------------------------------------------------------------------------------- World Acceptance Corp. 2.8% -- - -------------------------------------------------------------------------------- Omnicell Inc. 2.5% -- - -------------------------------------------------------------------------------- Illumina, Inc. 2.0% -- - -------------------------------------------------------------------------------- Digital River Inc. 2.0% 0.9% - -------------------------------------------------------------------------------- OM Group, Inc. 2.0% -- - -------------------------------------------------------------------------------- RenaissanceRe Holdings Ltd. 1.8% -- - -------------------------------------------------------------------------------- Watson Wyatt Worldwide Inc. 1.7% 1.2% - -------------------------------------------------------------------------------- SonicWALL, Inc. 1.7% -- - -------------------------------------------------------------------------------- WellCare Health Plans Inc. 1.6% -- - -------------------------------------------------------------------------------- Priceline.com Inc. 1.6% -- - -------------------------------------------------------------------------------- *Since 12/31/96, the date nearest the fund's inception for which data are available. (continued) - ------ 5 New Opportunities - Portfolio Commentary position and sound security selection in that sector boosted the portfolio's relative performance considerably. The materials sector contained the portfolio's largest average overweight position in the reporting period, Titanium Metals. For the second consecutive fiscal year, this maker of lightweight titanium materials for the aircraft industry topped the portfolio's list of leading individual stock performers, as its shares surged 149%. Two other companies in the sector, Zoltek and OM Group, also ranked among the portfolio's top five relative contributors. TROUBLE IN HEALTH CARE, TECHNOLOGY The bulk of New Opportunities' relative underperformance stemmed from our stock choices in health care and technology, including the portfolio's leading detractor, Quidel Corp. Quidel makes diagnostic test kits, including one for detecting the flu. Its share price plunged in late 2005, and we sold our stake in the company. The portfolio also suffered from security selection in the industrials sector, primarily from a stake in GrafTech International, an Ohio-based maker of fuel cells. The company lost more than a third of its market value in one trading session in early February 2006, a month before it reported a significant decline in its fourth-quarter 2005 operating profit. PORTFOLIO OBJECTIVE & EXPECTATIONS New Opportunities seeks long-term growth and is designed to provide small-cap exposure to a diversified investment portfolio. The portfolio is best suited for investors who can tolerate high levels of share price fluctuation in exchange for compelling long-term return potential. To achieve our objective, we pursue an investment approach of 1) identifying small companies that appear to have accelerating earnings and revenue growth and 2) buying those companies when potential rewards appear greatest.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 7 Shareholder Fee Example (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - ------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 -

ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. New Opportunities Fund (the fund) is one fund in a series issued by the corporation. The fund is diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth. The fund pursues its objective by investing primarily in common stocks of smaller-sized companies that management believes will increase in value over time. The following is a summary of the fund's significant accounting policies. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The fund estimates the components of distributions received that may be considered nontaxable distributions or capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The fund records the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with (continued) - ------ 14 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. REDEMPTION -- The fund may impose a 2% redemption fee on shares held less than 180 days. The redemption fee is recorded as a reduction in the cost of shares redeemed. The redemption fee is retained by the fund and helps cover transaction costs that long-term investors may bear when a fund sells securities to meet investor redemptions. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee). The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in the fund's investment strategy (strategy assets) to calculate the appropriate fee rate for the fund. The strategy assets include the fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. Effective August 1, 2006, the fund modified its management fee schedule, resulting in lower fee rates and breakpoints. There was no significant impact on the effective annual management fee for the year ended October 31, 2006 resulting from this change. Effective August 1, 2006, the annual management fee schedule for the fund is as follows: - ----------------------------------------------------- INVESTOR CLASS - ----------------------------------------------------- STRATEGY ASSETS - ----------------------------------------------------- First $250 million 1.50% - ----------------------------------------------------- Next $250 million 1.25% - ----------------------------------------------------- Next $250 million 1.15% - ----------------------------------------------------- Over $750 million 1.10% - ----------------------------------------------------- (continued) - ------ 15 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) The effective annual management fee for the fund for the year ended October 31, 2006 was 1.50%. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, American Century Investment Services, Inc., and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchases and sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, were $763,464 and $788,284, respectively. 4. BANK LINE OF CREDIT The fund, along with certain other funds managed by ACIM or ACGIM, has a $500 million unsecured bank line of credit agreement with JPMCB. The fund may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund did not borrow from the line during the year ended October 31, 2006. 5. RISK FACTORS The fund concentrates its investments in common stocks of small companies. Because of this, the fund may be subject to greater risk and market fluctuations than a fund investing in larger, more established companies. 6. FEDERAL TAX INFORMATION The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. There were no distributions paid by the fund during the years ended October 31, 2006 and October 31, 2005. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- Federal tax cost of investments $ 225,450 ================================================================================ Gross tax appreciation of investments $ 31,216 - ----------------------------------------------------------------- Gross tax depreciation of investments (1,209) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $ 30,007 ================================================================================ Undistributed ordinary income -- - ----------------------------------------------------------------- Accumulated capital losses $(120,290) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales and return of capital dividends. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers of $82,591 and $37,699 expire in 2009 through 2010, respectively. (continued) - ------ 16 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 7. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. - ------ 17 New Opportunities - Financial Highlights For a Share Outstanding Throughout the Years Ended October 31 - -------------------------------------------------------------------------------- 2006 2005 2004 2003 2002 - -------------------------------------------------------------------------------- PER-SHARE DATA - -------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $5.63 $5.06 $5.06 $4.01 $4.80 - -------------------------------------------------------------------------------- Income From Investment Operations - ------------------------- Net Investment Income (Loss) (0.06) (0.06) (0.06) (0.04) (0.05) - ------------------------- Net Realized and Unrealized Gain (Loss) 0.87 0.63 0.06 1.09 (0.74) - -------------------------------------------------------------------------------- Total From Investment Operations 0.81 0.57 -- 1.05 (0.79) - -------------------------------------------------------------------------------- Net Asset Value, End of Period $6.44 $5.63 $5.06 $5.06 $4.01 ================================================================================ TOTAL RETURN(1) 14.39% 11.26% 0.00% 26.18% (16.46)% - -------------------------------------------------------------------------------- RATIOS/SUPPLEMENTAL DATA - -------------------------------------------------------------------------------- Ratio of Operating Expenses to Average Net Assets 1.50% 1.50% 1.49% 1.50% 1.50% - ------------------------- Ratio of Net Investment Income (Loss) to Average Net Assets (0.84)% (0.98)% (1.04)% (0.98)% (1.02)% - ------------------------- Portfolio Turnover Rate 298% 260% 269% 217% 175% - ------------------------- Net Assets, End of Period (in thousands) $247,876 $240,464 $273,555 $318,226 $297,180 - -------------------------------------------------------------------------------- (1) Total return assumes reinvestment of net investment income and capital gains distributions, if any. See Notes to Financial Statements. - ------ 18 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of New Opportunities Fund, (the "Fund"), one of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of New Opportunities Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning New Opportunities (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of (continued) - ------ 23 Approval of Management Agreement for New Opportunties the advice of its independent counsel throughout the period. FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the fund. The (continued) - ------ 24 Approval of Management Agreement for New Opportunties Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance for the one year period was above the median for its peer group and below the median for the three year period during the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvestment in its ability to provide and (continued) - ------ 25 Approval of Management Agreement for New Opportunties expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was above the median of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They concluded that the advisor's primary business is managing mutual funds and (continued) - ------ 26 Approval of Management Agreement for New Opportunties it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, assisted by the advice of legal counsel independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor, negotiated changes to the breakpoint schedule used to calculate the fund's management fee. These changes were proposed by the Directors based on their review of the competitive changes in the mutual fund marketplace and their review of financial information provided by the advisor. The new schedule, effective August 1, 2006, contains lower management fees at certain asset levels than under the existing structure. Following these negotiations with the advisor, the independent directors concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 27 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply.

You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election.

Market Perspective [photo of Mark Mallon] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth--along with commodity prices, short-term interest rates, and inflation--surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve (the Fed) end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

By comparison, its new and old benchmarks (blended indices of 60% S&P 500 Index for both, and 40% Citigroup US Broad Investment-Grade Bond Index (BIG) for the new benchmark and 40% Lehman Brothers U.S. Aggregate Index for the old) rose 11.83% and 11.80%, respectively. We believe the new benchmark better represents the portfolio's composition. Strong stock market returns--resulting from a pause in the Federal Reserve's interest rate hikes and expectations for lower interest rates and mild inflation going forward--were the main driver behind the fund's and the benchmarks' absolute gains. Relative investment returns between the portfolio and its benchmarks were similar; the fund's results reflected operating expenses, while the benchmark returns did not. EQUITY PERFORMANCE & POSITIONING Net of operating expenses, Balanced's equity portfolio returned approximately 16% for the reporting period, compared with 16.34% for the S&P 500 (index returns are not reduced by expenses). Chief contributors to portfolio performance compared with the index included overweight positions in steel manufacturer Nucor Corp. (up 103%), engine-maker Cummins Inc. (up 51%), and health insurance provider Humana Inc. (up 35%). The biggest detractors from relative performance included overweight positions in poultry products producer Pilgrim's Pride (down 18%) and managed health care organization Sierra Health Services (down 9%).

(continued) - ------ 5 Balanced - Portfolio Commentary Aggregate and Citigroup BIG (index returns are not reduced by expenses). The returns of the portfolio and these indices are typically generated by mortgage-backed securities (MBS), commercial MBS (CMBS), asset-backed securities (ABS, backed by payments from credit card debt, auto loans, and home-equity lines of credit), high- and medium-grade corporate bonds, and U.S. government securities, including Treasurys and government agency bonds. During the period, longer-duration positions were rewarded. When bonds rallied in the third quarter of 2006, the bond portfolio's duration was slightly longer than neutral, giving performance a boost. Our strategy to overweight "spread" products (non-Treasury securities such as corporates, MBS, ABS, and CMBS) also benefited the fund since these sectors outperformed Treasurys during the reporting period. PORTFOLIO OBJECTIVES & EXPECTATIONS Balanced seeks long-term capital growth and current income by investing in diversified U.S. stock and bond portfolios, with an approximately 60/40 stock/bond mix. The equity portfolio's objective is to surpass the S&P 500 without taking on significant additional risk. We use a two-step approach for stock selection and portfolio construction, relying on computer models as key decision-making tools. The fixed-income portfolio is also index-oriented, providing a broad, roughly market capitalization-based mix of income-producing investment-grade debt securities. We use an active, multi-step process that seeks to identify the best relative value among bond sectors. We then apply appropriate yield curve/ duration positioning, security selection, and portfolio construction. Balanced is designed to serve as a core holding for investors seeking "ready-made" stock/bond diversification. It's also for investors seeking long-term growth with less volatility than pure growth-stock portfolios. The bond portfolio is designed to help cushion and offset the stock portfolio's performance swings while providing income; meanwhile the stock portfolio provides long-term growth potential, which is important to investors who wish to guard against inflation.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 7 Shareholder Fee Example (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - -------------------------------------------------------------------------------- BALANCED SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- ACTUAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,047.60 $4.64 0.90% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,049.30 $3.62 0.70% - -------------------------------------------------------------------------------- Advisor Class $1,000 $1,046.40 $5.93 1.15% - -------------------------------------------------------------------------------- HYPOTHETICAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,020.67 $4.58 0.90% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,021.68 $3.57 0.70% - -------------------------------------------------------------------------------- Advisor Class $1,000 $1,019.41 $5.85 1.15% - -------------------------------------------------------------------------------- *Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 8 Balanced - Schedule of Investments OCTOBER 31, 2006 Shares ($ IN THOUSANDS) Value - -------------------------------------------------------------------------------- COMMON STOCKS -- 60.1% AEROSPACE & DEFENSE -- 1.2% - -------------------------------------------------------------------------------- 8,571 Boeing Co. $ 684 - -------------------------------------------------------------------------------- 79,011 Lockheed Martin Corp. 6,869 - -------------------------------------------------------------------------------- 7,553 - -------------------------------------------------------------------------------- AIR FREIGHT & LOGISTICS -- 0.3% - -------------------------------------------------------------------------------- 3,554 FedEx Corporation 407 - -------------------------------------------------------------------------------- 19,638 United Parcel Service, Inc.

------ 21 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Balanced Fund (the fund) is one fund in a series issued by the corporation. The fund is diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth and current income. The fund pursues its objective by investing approximately 60% of its assets in equity securities and the remainder in bonds and other fixed-income securities. The following is a summary of the fund's significant accounting policies. MULTIPLE CLASS -- The fund is authorized to issue the Investor Class, the Institutional Class and the Advisor Class. The share classes differ principally in their respective distribution and shareholder servicing expenses and arrangements. All shares of the fund represent an equal pro rata interest in the assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Interest income is recorded on the accrual basis and includes paydown gain (loss) and accretion of discounts and amortization of premiums. SECURITIES ON LOAN -- The fund may lend portfolio securities through its lending agent to certain approved borrowers in order to earn additional income. The fund continues to recognize any gain or loss in the market price of the securities loaned and records any interest earned or dividends declared. FUTURES CONTRACTS -- The fund may enter into futures contracts in order to manage the fund's exposure to changes in market conditions. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the fund is required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. The fund recognizes a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on futures and swaps transactions and unrealized appreciation (depreciation) on futures and swaps, respectively. (continued) - ------ 22 Notes to Financial Statements OCTOBER 31, 2006 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) WHEN-ISSUED AND FORWARD COMMITMENTS -- The fund may engage in securities transactions on a when-issued or forward commitment basis. Under these arrangements, the securities' prices and yields are fixed on the date of the commitment, but payment and delivery are scheduled for a future date. During this period, securities are subject to market fluctuations. The fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet the purchase price. SWAP AGREEMENTS -- The fund may enter into a swap agreement in order to attempt to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets; protect against currency fluctuations; attempt to manage duration to protect against any increase in the price of securities the fund anticipates purchasing at a later date; or gain exposure to certain markets in the most economical way possible. A basic swap agreement is a contract in which two parties agree to exchange the returns earned or realized on predetermined investments or instruments. Credit default swaps enable an investor to buy/sell protection against a credit event of a specific issuer. The seller of credit protection against a security or basket of securities receives an up-front or periodic payment to compensate against potential default events. The fund may enhance returns by selling protection or attempt to mitigate credit risk by buying protection. The fund will segregate cash, cash equivalents or other appropriate liquid securities on its records in amounts sufficient to meet requirements. Unrealized gains are reported as an asset and unrealized losses are reported as a liability on the Statement of Assets and Liabilities. Swap agreements are valued daily and changes in value, including the periodic amounts of interest to be paid or received on swaps, are recorded as unrealized appreciation (depreciation) on futures and swaps. Realized gain or loss is recorded upon receipt or payment of a periodic settlement or termination of swap agreements. The risks of entering into swap agreements include the possible lack of liquidity, failure of the counterparty to meet its obligations, and that there may be unfavorable changes in the underlying investments and instruments. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income are declared and paid quarterly. Distributions from net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements.

FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of the specific class of shares of the fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in the fund's investment strategy (strategy assets) to calculate the appropriate fee rate for the fund. The strategy assets include the fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The annual management fee schedule for each class of the fund is as follows: INVESTOR INSTITUTIONAL ADVISOR - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $1 billion 0.90% 0.70% 0.65% - -------------------------------------------------------------------------------- Over $1 billion 0.80% 0.60% 0.55% - -------------------------------------------------------------------------------- The effective annual management fee for each class of the fund for the year ended October 31, 2006 was 0.90%, 0.70% and 0.65%, for the Investor Class, Institutional Class and Advisor Class, respectively. DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master Distribution and Shareholder Services Plan (the plan) for the Advisor Class, pursuant to Rule 12b-1 of the 1940 Act. The plan provides that the Advisor Class will pay American Century Investment Services, Inc. (ACIS) an annual distribution fee equal to 0.25% and an annual service fee equal to 0.25%. The fees are computed and accrued daily based on the Advisor Class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred by financial intermediaries in connection with distributing shares of the Advisor Class including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the fund. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers. Fees incurred under the plan during the year ended October 31, 2006, are detailed in the Statement of Operations. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement and securities lending agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchases of investment securities, excluding short-term investments, for the year ended October 31, 2006, totaled $1,241,785, of which $744,450 represented U.S. Treasury and Agency obligations. Sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, totaled $1,282,568, of which $740,679 represented U.S. Treasury and Agency obligations.

SECURITIES LENDING As of October 31, 2006, securities in the fund valued at $54,040, were on loan through the lending agent, JPMCB, to certain approved borrowers. JPMCB receives and maintains collateral in the form of cash and/or acceptable securities as approved by ACIM. Cash collateral is invested in authorized investments by the lending agent in a pooled account. The value of cash collateral received at period end is disclosed in the Statement of Assets and Liabilities and investments made with the cash by the lending agent are listed in the Schedule of Investments. Any deficiencies or excess of collateral must be delivered or transferred by the member firms no later than the close of business on the next business day. The total value of all collateral received, at this date, was $55,084. The fund's risks in securities lending are that the borrower may not provide additional collateral when required or return the securities when due. If the borrower defaults, receipt of the collateral by the fund may be delayed or limited. 6. BANK LINE OF CREDIT The fund, along with certain other funds managed by ACIM or ACGIM, has a $500 million unsecured bank line of credit agreement with JPMCB. The fund may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund did not borrow from the line during the year ended October 31, 2006. 7. FEDERAL TAX INFORMATION The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 were as follows: - -------------------------------------------------------------------------------- 2006 2005 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - -------------------------------------------------------------------------------- Ordinary income $16,917 $11,354 - -------------------------------------------------------------------------------- Long-term capital gains $30,576 -- - -------------------------------------------------------------------------------- The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of paydown losses, interest on swap agreements, certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- Federal tax cost of investments $679,156 ================================================================================ Gross tax appreciation of investments $68,108 - -------------------------------------------------------------- Gross tax depreciation of investments (3,618) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $64,490 ================================================================================ Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies (688) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $63,802 ================================================================================ Undistributed ordinary income $2,339 - -------------------------------------------------------------- Accumulated long-term gains $24,539 - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on certain futures contracts.

RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. 9.

See Notes to Financial Statements. - ------ 30 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Balanced Fund, (the "Fund"), one of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Balanced Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Balanced (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of the advice of its independent counsel throughout the period. (continued) - ------ 35 Approval of Management Agreement for Balanced FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate benchmarks and peer groups of funds managed similarly to the fund. The Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not managed by the advisor. If performance (continued) - ------ 36 Approval of Management Agreement for Balanced concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance for both the one and three year periods was above the median for its peer group. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvestment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee break- (continued) - ------ 37 Approval of Management Agreement for Balanced points as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was below the median of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to (continued) - ------ 38 Approval of Management Agreement for Balanced serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, in the absence of particular circumstances and assisted by the advice of legal counsel that is independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 39 Share Class Information Three classes of shares are authorized for sale by the fund: Investor Class, Institutional Class, and Advisor Class. The total expense ratio of Institutional Class shares is lower than that of Investor Class shares. The total expense ratio of Advisor Class shares is higher than that of Investor Class shares. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. ADVISOR CLASS shares are sold primarily through institutions such as investment advisors, banks, broker-dealers, insurance companies, and financial advisors. Advisor Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. The total expense ratio of Advisor Class shares is 0.25% higher than the total expense ratio of Investor Class shares. All classes of shares represent a pro rata interest in the fund and generally have the same rights and preferences. - ------ 40 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

(continued) - ------ 41 Index Definitions The following indices are used to illustrate investment market, sector, or style performance or to serve as fund performance comparisons. They are not investment products available for purchase. The BLENDED INDEX is considered the benchmark for Balanced. It combines two widely known indices in proportion to the asset mix of the fund. Accordingly, 60% of the index is represented by the S&P 500 Index, which reflects the approximately 60% of the fund's assets invested in stocks. The old blended index's remaining 40% was represented by the Lehman Brothers U.S. Aggregate Index, which reflects the roughly 40% of the fund's assets invested in fixed-income securities. However, the new blended index's remaining 40% is represented by the Citigroup US Broad Investment-Grade Bond Index. The change in the blended index better represents the fund's portfolio composition. The CITIGROUP US BROAD INVESTMENT-GRADE (BIG) BOND INDEX is a market-capitalization-weighted index that includes fixed-rate Treasury, government-sponsored, mortgage, asset-backed, and investment-grade issues with a maturity of one year or longer. The DOW JONES INDUSTRIAL AVERAGE (DJIA) is a price-weighted average of 30 actively traded blue chip stocks, primarily industrials but including service-oriented firms. Prepared and published by Dow Jones & Co., it is the oldest and most widely quoted of all the market indicators. The LEHMAN BROTHERS U.S. AGENCY INDEX is composed of those securities included in the Lehman Brothers U.S. Aggregate Index that are public obligations of U.S. government agencies, quasi-federal corporations, and corporate or foreign debt guaranteed by the U.S. government. The LEHMAN BROTHERS U.S. AGGREGATE INDEX represents securities that are taxable, registered with the Securities and Exchange Commission, and U.S. dollar-denominated. The index covers the U.S. investment-grade fixed-rate bond market, with index components for government and corporate securities, mortgage pass-through securities, and asset-backed securities. The LEHMAN BROTHERS U.S. CORPORATE INDEX is composed of those securities included in the Lehman Brothers U.S. Aggregate Index that are U.S. dollar-denominated, investment-grade, fixed-rate, taxable securities sold by industrial, utility and financial issuers. The LEHMAN BROTHERS U.S. FIXED-RATE MORTGAGE-BACKED SECURITIES (MBS) INDEX is the MBS Fixed-Rate component of the Lehman Brothers U.S. Aggregate Index. It covers the mortgage-backed pass-through securities of the Government National Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA), and the Federal Home Loan Mortgage Corporation (FHLMC). The LEHMAN BROTHERS U.S. TREASURY INDEX is composed of those securities included in the Lehman Brothers U.S. Aggregate Index that are public obligations of the U.S. Treasury with a remaining maturity of one year or more. The NASDAQ COMPOSITE INDEX is a market value-weighted index of all domestic and international common stocks listed on the Nasdaq stock market. (continued) - ------ 42 Index Definitions The RUSSELL 2000(reg.tm) INDEX is a market-capitalization weighted index created by Frank Russell Company to measure the performance of the 2,000 smallest of the 3,000 largest publicly traded U.S. companies, based on total market capitalization. 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. Each stock's weight in the index is proportionate to its market value. Created by Standard & Poor's, it is considered to be a broad measure of U.S. stock market performance. - ------ 43 Notes - ------ 44 [back cover] CONTACT US AMERICANCENTURY.COM AUTOMATED INFORMATION LINE: 1-800-345-8765 INVESTOR SERVICES REPRESENTATIVE: 1-800-345-2021 or 816-531-5575 BUSINESS, NOT-FOR-PROFIT, EMPLOYER-SPONSORED RETIREMENT PLANS: 1-800-345-3533 BANKS AND TRUST COMPANIES, BROKER-DEALERS, FINANCIAL PROFESSIONALS, INSURANCE COMPANIES: 1-800-345-6488 TELECOMMUNICATIONS DEVICE FOR THE DEAF: 1-800-634-4113 or 816-444-3485 AMERICAN CENTURY MUTUAL FUNDS, INC.

Market Perspective [photo of Chief Investment Officer] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

PERFORMANCE SUMMARY Veedot gained 10.77%* during the 12-month period ended October 31, 2006, trailing the 16.37% return of its broad market benchmark, the Russell 3000 Index. A pause in Federal Reserve interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10-25% range for the 12-month period, despite a sizeable market selloff from mid-May to mid-June 2006. After almost doubling the return of its benchmark in the first half of the reporting period, the portfolio struggled on both an absolute and relative basis after the selloff. Our systematic investment process guides us to stocks that show acceleration in earnings and revenue and does not reflect any consideration of external benchmark sector, industry, or individual stock weights. In the first half of the reporting period, our process led us to overweight positions in numerous sectors -- especially industrials and materials -- that had enjoyed sound financial growth. Strong returns in those sectors in the first half of the period reflected that growth. However, the market's selloff and an ensuing rebound late in the period encompassed a broad shift away from the sectors that had worked well in early 2006. As a result, several of the stocks and sectors responsible for Veedot's surge in the first half of the reporting period detracted from performance in the second half of the period. In addition, investors generally did not favor growth and momentum factors, such as accelerating stock prices or financial results. Veedot relies heavily on such factors in its investment process. The recent volatility is not unusual for Veedot; that's one of the expected trade-offs for high potential long-term returns. Despite its struggles at the end of the reporting period, Veedot's 3.08% average annual return since its November 30, 1999, inception surpassed the 2.57% return of its benchmark for the same period. ENERGY PICKS SUFFERED We gradually reduced our exposure to the energy sector as the period progressed and energy prices declined. Nonetheless, an overweight position in the sector hurt the portfolio's relative return, and three of our 10 worst relative performers came from that sector, including overweights in several smaller oil and gas producers. Veedot also suffered from an underweight stake in Exxon Mobil, which surged 30% in the reporting period. One of the smaller producers, Blue Dolphin Energy, highlighted the market's bumpy transition in May 2006.

(continued) - ------ 5 Veedot - Portfolio Commentary cap company's shares actually surged 79% for the full reporting period. But after nearly quadrupling in early April, the company's shares lost half their value between mid-April and mid-May. We purchased the stock on its upswing in late April and sold our stake by the end of May, but not before enduring its quick decline. Within health care, Veedot's worst relative performer, NPS Pharmaceuticals, fell 38% in one trading session in early March. The share decline occurred after the U.S. Food and Drug Administration requested additional clinical information concerning an osteoporosis drug the company wants to market. Our technical process flags such precipitous declines, and we quickly shed our position in the company. TOP HOLDING LED RETURNS Geo Group, one of the portfolio's five heaviest average individual holdings and one of our biggest overweight stakes, topped the list of leading relative and absolute performers by a substantial margin. Shares in the Florida-based operator of correctional facilities soared 161% in the period, primarily resulting from strong earnings growth. Our position in Geo Group explained the bulk of our relative outperformance in the industrials sector. We also reaped relative and absolute gains from the information technology sector, despite maintaining a detrimental overweight position in the sector. Several picks in the electronic equipment and computer industries boosted performance. But Anadigics, a New Jersey-based producer of integrated circuits and radio frequency solutions for wireless handset and broadband applications, provided the biggest individual contribution from the sector. Its shares rose 141% amid booming demand for the company's products. PORTFOLIO OBJECTIVE & EXPECTATIONS Veedot is best-suited for investors who can tolerate short-term share price fluctuation as the fund seeks long-term capital growth. Using a systematic and technically driven investment process, we focus on finding companies whose fundamental characteristics meet strict requirements for accelerating earnings and revenue growth. For inclusion into the portfolio, such companies also must have historical stock price performance that suggests impending share price appreciation. We believe Veedot is poised for solid returns if the market rebound that began late in the reporting period persists and predictions for Federal Reserve rate cuts in 2007 prove correct.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical (continued) - ------ 7 Shareholder Fee Example (Unaudited) example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - -------------------------------------------------------------------------------- VEEDOT SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- ACTUAL - -------------------------------------------------------------------------------- Investor Class $1,000 $955.10 $6.80 1.38% - -------------------------------------------------------------------------------- Institutional Class $1,000 $957.10 $5.82 1.18% - -------------------------------------------------------------------------------- HYPOTHETICAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,018.25 $7.02 1.38% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,019.26 $6.01 1.18% - -------------------------------------------------------------------------------- *Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 8 Veedot - Schedule of Investments OCTOBER 31, 2006 Shares Value - -------------------------------------------------------------------------------- COMMON STOCKS -- 96.7% - -------------------------------------------------------------------------------- AEROSPACE & DEFENSE - 3.0% - -------------------------------------------------------------------------------- 53,500 HEICO Corp. $ 1,940,980 - -------------------------------------------------------------------------------- 22,000 Precision Castparts Corp. 1,497,320 - -------------------------------------------------------------------------------- 36,000 Teledyne Technologies Inc.(1) 1,501,920 - -------------------------------------------------------------------------------- 4,940,220 - -------------------------------------------------------------------------------- BIOTECHNOLOGY - 1.7% - -------------------------------------------------------------------------------- 30,000 Digene Corp.(1) 1,392,900 - -------------------------------------------------------------------------------- 42,000 MedImmune, Inc.(1) 1,345,680 - -------------------------------------------------------------------------------- 2,738,580 - -------------------------------------------------------------------------------- BUILDING PRODUCTS - 0.9% - -------------------------------------------------------------------------------- 23,500 NCI Building Systems Inc.(1) 1,406,475 - -------------------------------------------------------------------------------- CAPITAL MARKETS - 1.8% - -------------------------------------------------------------------------------- 68,000 Janus Capital Group Inc. 1,365,440 - -------------------------------------------------------------------------------- 20,500 Morgan Stanley 1,566,815 - -------------------------------------------------------------------------------- 2,932,255 - -------------------------------------------------------------------------------- CHEMICALS - 0.9% - -------------------------------------------------------------------------------- 55,500 Lyondell Chemical Co. 1,424,685 - -------------------------------------------------------------------------------- COMMERCIAL BANKS - 0.9% - -------------------------------------------------------------------------------- 71,500 Sun Bancorp Inc.(1) 1,485,055 - -------------------------------------------------------------------------------- COMMERCIAL SERVICES & SUPPLIES - 3.4% - -------------------------------------------------------------------------------- 112,500 Geo Group Inc.

------ 14 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Veedot Fund (the fund) is one fund in a series issued by the corporation. The fund is non-diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth. The fund pursues its objective by investing primarily in common stocks that management believes to have better than average prospects for appreciation. The fund uses an approach to common stock investing developed by American Century. This approach relies heavily on quantitative tools to identify attractive investment opportunities, regardless of company size, industry type or geographic location, on a disciplined, consistent basis. The following is a summary of the fund's significant accounting policies. MULTIPLE CLASS -- The fund is authorized to issue the Investor Class and the Institutional Class. The share classes differ principally in their respective distribution and shareholder servicing expenses and arrangements. All shares of the fund represent an equal pro rata interest in the assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain, are recorded as a reduction of cost of investments and/or as a realized gain. The fund estimates the components of distributions received that may be considered nontaxable distributions or capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums FUTURES CONTRACTS -- The fund may enter into futures contracts in order to manage the fund's exposure to changes in market conditions. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the fund is required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the fund. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. The fund recognizes a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. (continued) - ------ 15 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The fund records the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The fund may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the fund's exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the fund and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The fund bears the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net in vestment income and net realized gains, if any, are generally declared and paid annually. REDEMPTION -- The fund may impose a 2% redemption fee on shares held less than five years. The redemption fee is recorded as a reduction in the cost of shares redeemed. The redemption fee is retained by the fund and helps cover transaction costs that long-term investors may bear when a fund sells securities to meet investor redemptions. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. (continued) - ------ 16 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of the specific class of shares of the fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in the fund's investment strategy (strategy assets) to calculate the appropriate fee rate for the fund. The strategy assets include the fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. Effective August 1, 2006, the fund modified its management fee schedule, resulting in lower fee rates and higher breakpoints. There was a reduction of the effective annual management fee for the year ended October 31, 2006 resulting from this change. Effective August 1, 2006, the annual management fee schedule for each class of the fund is as follows: - -------------------------------------------------------------------------------- INVESTOR INSTITUTIONAL CLASS CLASS - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $500 million 1.25% 1.05% - -------------------------------------------------------------------------------- Next $500 million 1.10% 0.90% - -------------------------------------------------------------------------------- Over $1 billion 1.00% 0.80% - -------------------------------------------------------------------------------- The effective annual management fee for each class of the fund for the year ended October 31, 2006 was 1.45% and 1.25% for the Investor Class and Institutional Class, respectively. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, American Century Investment Services, Inc., and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchase and sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, were $594,271,181 and $640,897,817, respectively.

(2) Net of redemption fees of $334,934. (3) Net of redemption fees of $1,699. 5. BANK LINE OF CREDIT The fund, along with certain other funds managed by ACIM or ACGIM, has a $500,000,000 unsecured bank line of credit agreement with JPMCB. The fund may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund did not borrow from the line during the year ended October 31, 2006. 6. RISK FACTORS The fund's investment process may involve high portfolio turnover and high capital gains distributions. In addition, its investment approach may involve higher volatility and risk. (continued) - ------ 18 Notes to Financial Statements OCTOBER 31, 2006 7. FEDERAL TAX INFORMATION The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. There were no distributions paid by the fund during the years ended October 31, 2006 and October 31, 2005. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- Federal tax cost of investments $151,573,843 ================================================================================ Gross tax appreciation of investments $15,855,588 - -------------------------------------------------------------- Gross tax depreciation of investments (1,168,421) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $14,687,167 ================================================================================ Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies -- - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $14,687,167 ================================================================================ Undistributed ordinary income -- - -------------------------------------------------------------- Accumulated capital losses $(69,794,205) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers expire as follows: - -------------------------------------------------------------------------------- 2009 2010 - -------------------------------------------------------------------------------- $(37,476,753) $(32,317,452) - -------------------------------------------------------------------------------- 8. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. - ------ 19 Veedot - Financial Highlights For a Share Outstanding Throughout the Years Ended October 31 - -------------------------------------------------------------------------------- INVESTOR CLASS - -------------------------------------------------------------------------------- 2006 2005 2004 2003 2002 - -------------------------------------------------------------------------------- PER-SHARE DATA - -------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $5.57 $5.06 $4.99 $3.77 $4.32 - -------------------------------------------------------------------------------- Income From Investment Operations - ------------------------- Net Investment Income (Loss)(1) (0.02) (0.03) (0.03) (0.03) (0.01) - ------------------------- Net Realized and Unrealized Gain (Loss) 0.62 0.53 0.09 1.24 (0.55) - -------------------------------------------------------------------------------- Total From Investment Operations 0.60 0.50 0.06 1.21 (0.56) - -------------------------------------------------------------------------------- Redemption Fees(1) --(2) 0.01 0.01 0.01 0.01 - -------------------------------------------------------------------------------- Net Asset Value, End of Period $6.17 $5.57 $5.06 $4.99 $3.77 ================================================================================ TOTAL RETURN(3) 10.77% 10.08% 1.40% 32.36% (12.73)% - -------------------------------------------------------------------------------- RATIOS/SUPPLEMENTAL DATA - -------------------------------------------------------------------------------- Ratio of Operating Expenses to Average Net Assets 1.45% 1.50% 1.50% 1.50% 1.50% - ------------------------- Ratio of Net Investment Income (Loss) to Average Net Assets (0.39)% (0.51)% (0.57)% (0.68)% (0.31)% - ------------------------- Portfolio Turnover Rate 330% 399% 344% 415% 330% - ------------------------- Net Assets, End of Period (in thousands) $154,374 $178,078 $219,618 $228,724 $187,451 - -------------------------------------------------------------------------------- (1) Computed using average shares outstanding throughout the period.

These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Veedot Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Veedot (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of (continued) - ------ 27 Approval of Management Agreement for Veedot the advice of its independent counsel throughout the period. FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate bench- (continued) - ------ 28 Approval of Management Agreement for Veedot marks and peer groups of funds managed similarly to the fund. The Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance fell below the median for both the one and three year periods during the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinvest- (continued) - ------ 29 Approval of Management Agreement for Veedot ment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was above the median of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They (continued) - ------ 30 Approval of Management Agreement for Veedot concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, assisted by the advice of legal counsel independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor, negotiated changes to the breakpoint schedule used to calculate the fund's management fee. These changes were proposed by the Directors based on their review of the competitive changes in the mutual fund marketplace and their review of financial information provided by the advisor. The new schedule, effective August 1, 2006, contains lower management fees at certain asset levels than under the existing structure. Following these negotiations with the advisor, the independent directors concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 31 Share Class Information Two classes of shares are authorized for sale by the fund: Investor Class and Institutional Class. The total expense ratio for Institutional Class shares is lower than that of Investor Class shares. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. All classes of shares represent a pro rata interest in the fund and generally have the same rights and preferences. - ------ 32 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective [photo of Chief Investment Officer] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS ECONOMIC GROWTH SURGED, THEN MODERATED Economic growth -- along with commodity prices, short-term interest rates, and inflation -- surged early in the 12-month period ended October 31, 2006. But growth and inflation moderated in the period's second half, which saw the Federal Reserve end its two-year string of interest rate hikes. After a hurricane-related slowdown in the fourth quarter of 2005, U.S. gross domestic product grew in the first quarter of 2006 at a 5.6% annualized pace, the highest level in more than two years. The Fed steadily raised short-term interest rates through June to keep inflation in check, including pressures from soaring commodity prices. The Fed finally snapped its string of rate hikes in August 2006, leaving its target at 5.25%, a five-year high. By then, economic growth had slowed, dragged down in part by a cooling housing market. BEST FISCAL-YEAR STOCK RETURNS SINCE 2003 The Fed's pause and expectations for lower interest rates and mild inflation going forward helped produce the best U.S. stock returns for a 12-month fiscal period ended October 31 since 2003. Market rallies beginning and ending the period offset a late-spring/early-summer selloff. Growth stocks flourished in the latter rally, but value stocks outperformed growth for the full reporting period. Likewise, though large-cap stocks gained ground late in the period, small-caps posted higher returns for the entire 12-month stretch. In the first half of the 12-month period, investors celebrated a dip in crude oil prices and strong economic growth by pushing stock prices higher. The small-cap Russell 2000 Index led the way, surging 18.91%. Sentiment changed in early May, however, when the Fed made it clear that more interest rate hikes might be necessary to control inflation. Between April 30 and July 15, the S&P 500 fell 5.28%, and the Russell 2000 more than doubled that loss as investors desired larger, more stable companies. The selloff ended in late July after Fed chairman Ben Bernanke predicted inflation would moderate. The Fed's subsequent rate pause in August and plunging energy prices allowed stocks to rebound nicely in the last three months of the reporting period.

By comparison, its benchmark, the Russell 1000 Value Index, gained 21.46% and the broader market, as measured by the S&P 500, returned 16.34%.** As outlined in the Market Perspective on page 2, a pause in the Federal Reserve's interest rate hikes and expectations for lower interest rates and mild inflation going forward helped produce U.S. stock index returns in the 10% - 25% range for the 12-month period. In relative terms, value stocks outperformed for the period, helping us outpace the S&P 500. Amid mixed economic signals, investors rediscovered the kinds of companies we find appealing, gravitating toward investments in large, value-oriented firms with reliable earnings. It's worth mentioning Capital Value's solid performance since its March 31, 1999, inception. Our consistent, patient approach has produced an average annual return of 8.12%, compared with the 7.35% return of its benchmark and the 2.51% return of the S&P 500 for the same period. FINANCIALS: THE TOP CONTRIBUTOR Capital Value's stake in the financials sector, its largest sector position, made the biggest contribution to total return. Diversified financial services firms were the strongest performers, and all of our holdings in the industry--Bank of America, JPMorgan Chase, and Citigroup--finished among the top-contributing stocks. The energy sector was another source of strength on an absolute basis. We focused on diversified multinational oil and gas companies and remained selective, holding only a handful of names. Though it was a volatile period for energy stocks as oil prices came off their highs, we sidestepped broader damage, and most of our holdings--including Exxon Mobil, the top-contributing stock--posted gains. Holdings in the telecommunications services sector represented additional bright spots, particularly among diversified telecom firms. AT&T was a noteworthy name in that industry. The company announced strong second-quarter earnings, driven by the success of its merger with SBC Communications and increased contributions from Cingular Wireless. AT&T's share price jumped sharply on the earnings news and climbed for the remainder of the period. Finally, our stake in the health care sector performed well.

(continued) - ------ 5 Capital Value - Portfolio Commentary rewarded when long-time holdings in the pharmaceutical industry, some of which have struggled in the past, became solid performers. Industry leader Pfizer paced gains. Despite the challenges of generic competition and patent expirations, the company's stock rebounded nicely from its July lows on robust earnings reports driven by strength in key drugs such as Lipitor, the largest-selling medicine in the world. SOME DISAPPOINTMENTS Unfortunately, we made some decisions that caused us to trail the benchmark for the reporting period. Our position in the consumer discretionary sector detracted the most from relative performance. The benchmark's collection of holdings in the multi-line retail and media industries, many of which recorded powerful gains, outperformed the portfolio's handful of investments. Security selection worked against us in both industries and yielded the portfolio's top-detracting stock. Discount retailer Dollar General struggled during the period, and our portfolio overweight position compared with the benchmark proved costly. Dollar General's profits were squeezed by an unfavorable sales mix, lower-than-expected back-to-school sales, and high gasoline prices that raised transportation costs and slowed spending by the chain's low-income customers. Elsewhere, stock selection in the industrials sector worked against us, particularly in the machinery industry. Exposure to Ingersoll Rand--present in the portfolio but not in the benchmark--dampened relative performance. This stock declined following an analyst's downgrade based on lowered expectations for profit growth in the months ahead. PORTFOLIO OBJECTIVE & EXPECTATIONS Capital Value is designed to for investors seeking long-term capital growth who can tolerate relatively moderate share price fluctuation compared with volatility from more aggressive, growth-oriented investments. The fund can serve as a solid core holding in a diversified portfolio, with the capability to outperform growth-oriented investments when the value discipline is more in favor, as it was for much of the reporting period. Investors should keep in mind, though, that Capital Value could lag growth-oriented investments when the growth discipline is in favor.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 7 Shareholder Fee Example (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD* ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO* - -------------------------------------------------------------------------------- CAPITAL VALUE SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- ACTUAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,075.80 $5.76 1.10% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,077.10 $4.71 0.90% - -------------------------------------------------------------------------------- Advisor Class $1,000 $1,074.60 $7.06 1.35% - -------------------------------------------------------------------------------- HYPOTHETICAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,019.66 $5.60 1.10% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,020.67 $4.58 0.90% - -------------------------------------------------------------------------------- Advisor Class $1,000 $1,018.40 $6.87 1.35% - -------------------------------------------------------------------------------- *Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 8 Capital Value - Schedule of Investments OCTOBER 31, 2006 Shares Value - -------------------------------------------------------------------------------- COMMON STOCKS -- 95.1% - -------------------------------------------------------------------------------- AEROSPACE & DEFENSE - 0.8% - -------------------------------------------------------------------------------- 63,700 Northrop Grumman Corp. $ 4,229,043 - -------------------------------------------------------------------------------- AUTO COMPONENTS - 0.3% - -------------------------------------------------------------------------------- 43,800 Lear Corporation 1,323,198 - -------------------------------------------------------------------------------- BEVERAGES - 1.8% - -------------------------------------------------------------------------------- 113,700 Coca-Cola Company (The) 5,312,064 - -------------------------------------------------------------------------------- 117,300 Pepsi Bottling Group Inc. 3,709,026 - -------------------------------------------------------------------------------- 9,021,090 - -------------------------------------------------------------------------------- CAPITAL MARKETS - 4.1% - -------------------------------------------------------------------------------- 128,400 Bank of New York Co., Inc.

------ 13 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Capital Value Fund (the fund) is one fund in a series issued by the corporation. The fund is diversified under the 1940 Act. The fund's investment objective is to seek long-term capital growth. The fund pursues its objective by investing primarily in common stocks that management believes to be undervalued at the time of purchase. The fund also seeks to minimize the impact of federal income taxes on shareholder returns by attempting to minimize taxable distributions to shareholders. The following is a summary of the fund's significant accounting policies. MULTIPLE CLASS -- The fund is authorized to issue the Investor Class, the Institutional Class and the Advisor Class. The share classes differ principally in their respective distribution and shareholder servicing expenses and arrangements. All shares of the fund represent an equal pro rata interest in the assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the fund are allocated to each class of shares based on their relative net assets. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the fund determines that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the fund to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is the fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal (continued) - ------ 14 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the fund. In addition, in the normal course of business, the fund enters into contracts that provide general indemnifications. The fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the fund. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the fund with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the fund, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of the specific class of shares of the fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in the fund's investment strategy (strategy assets) to calculate the appropriate fee rate for the fund. The strategy assets include the fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The annual management fee schedule for each class of the fund is as follows: - -------------------------------------------------------------------------------- INVESTOR INSTITUTIONAL ADVISOR CLASS CLASS CLASS - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $500 million 1.10% 0.90% 0.85% - -------------------------------------------------------------------------------- Next $500 million 1.00% 0.80% 0.75% - -------------------------------------------------------------------------------- Over $1 billion 0.90% 0.70% 0.65% - -------------------------------------------------------------------------------- The effective annual management fee for each class of the fund for the year ended October 31, 2006, was 1.10%, 0.90%, and 0.85%, for the Investor Class, Institutional Class and Advisor Class, respectively. DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master Distribution and Shareholder Services Plan (the plan) for the Advisor Class, pursuant to Rule 12b-1 of the 1940 Act. The plan provides that the Advisor Class will pay American Century Investment Services, Inc. (ACIS) an annual distribution fee equal to 0.25% and an annual service fee equal to 0.25%. The fees are computed and accrued daily based on the Advisor Class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred by financial intermediaries in connection with distributing shares of the Advisor Class including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the fund. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers. Fees incurred under the plan during the year ended October 31, 2006, are detailed in the Statement of Operations. (continued) - ------ 15 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. The fund has a bank line of credit agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the fund and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Purchases and sales of investment securities, excluding short-term investments, for the year ended October 31, 2006, were $77,591,919 and $152,608,438, respectively.

BANK LINE OF CREDIT The fund, along with certain other funds managed by ACIM or ACGIM, has a $500,000,000 unsecured bank line of credit agreement with JPMCB. The fund may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund did not borrow from the line during the year ended October 31, 2006. 6. FEDERAL TAX INFORMATION The tax character of distributions paid during the years ended October 31, 2006 and October 31, 2005 were as follows: - -------------------------------------------------------------------------------- 2006 2005 - -------------------------------------------------------------------------------- DISTRIBUTIONS PAID FROM - -------------------------------------------------------------------------------- Ordinary income $7,252,535 $3,600,914 - -------------------------------------------------------------------------------- Long-term capital gains $5,771,196 -- - -------------------------------------------------------------------------------- The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- Federal tax cost of investments $400,501,212 ================================================================================ Gross tax appreciation of investments $114,200,222 - --------------------------------------------------------------- Gross tax depreciation of investments (661,636) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $113,538,586 ================================================================================ Undistributed ordinary income $5,370,151 - --------------------------------------------------------------- Accumulated long-term gains $6,808,253 - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales. (continued) - ------ 18 Notes to Financial Statements OCTOBER 31, 2006 7. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. 8. OTHER TAX INFORMATION (UNAUDITED) The following information is provided pursuant to provisions of the Internal Revenue Code.

See Notes to Financial Statements. - ------ 22 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Capital Value Fund, (the "Fund"), one of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for the periods presented. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Capital Value Fund as of October 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for the periods presented, in conformity with accounting principles generally accepted in the United States of America.

At American Century, this process is referred to as the "15(c) Process." As a part of this process, the board reviews fund performance, shareholder services, audit and compliance information, and a variety of other reports from the advisor concerning fund operations. In addition to this annual review, the board of directors oversees and evaluates on a continuous basis at its quarterly meetings the nature and quality of significant services performed by the advisor, fund performance, audit and compliance information, and a variety of other reports relating to fund operations. The board, or committees of the board, also holds special meetings as needed. Under a Securities and Exchange Commission rule, each fund is required to disclose in its annual or semiannual report, as appropriate, the material factors and conclusions that formed the basis for the board's approval or renewal of any advisory agreements within the fund's most recently completed fiscal half-year period. ANNUAL CONTRACT REVIEW PROCESS As part of the annual 15(c) Process undertaken during the most recent fiscal half-year period, the Directors reviewed extensive data and information compiled by the advisor and certain independent providers of evaluative data (the "15(c) Providers") concerning Capital Value (the "fund") and the services provided to the fund under the management agreement. The information considered and the discussions held at the meetings included, but were not limited to: * the nature, extent and quality of investment management, shareholder services and other services provided to the fund under the management agreement; * reports on the advisor's activities relating to the wide range of programs and services the advisor provides to the fund and its shareholders on a routine and non-routine basis; * data comparing the cost of owning the fund to the cost of owning a similar fund; * data comparing the fund's performance to appropriate benchmarks and/or a peer group of other mutual funds with similar investment objectives and strategies; * financial data showing the profitability of the fund to the advisor and the overall profitability of the advisor; and * data comparing services provided and charges to other investment management clients of the advisor. In keeping with its practice, the fund's board of directors held two regularly scheduled meetings and one special meeting to review and discuss the information provided by the advisor and to complete its negotiations with the advisor regarding the renewal of the management agreement, including the setting of the applicable advisory fee. The board also had the benefit of (continued) - ------ 28 Approval of Management Agreement for Capital Value the advice of its independent counsel throughout the period. FACTORS CONSIDERED The Directors considered all of the information provided by the advisor, the 15(c) Providers, and the board's independent counsel, and evaluated such information for each fund for which the board has responsibility. The Directors did not identify any single factor as being all-important or controlling, and each Director may have attributed different levels of importance to different factors. In deciding to renew the agreement under the terms ultimately determined by the board to be appropriate, the Directors' decision was based on the following factors. NATURE, EXTENT AND QUALITY OF SERVICES - GENERALLY. Under the management agreement, the advisor is responsible for providing or arranging for all services necessary for the operation of the fund. The board noted that under the management agreement, the advisor provides or arranges at its own expense a wide variety of services including: * fund construction and design * portfolio security selection * initial capitalization/funding * securities trading * custody of fund assets * daily valuation of the fund's portfolio * shareholder servicing and transfer agency, including shareholder confirmations, recordkeeping and communications * legal services * regulatory and portfolio compliance * financial reporting * marketing and distribution The Directors noted that many of these services have expanded over time both in terms of quantity and complexity in response to shareholder demands, competition in the industry and the changing regulatory environment. In performing their evaluation, the Directors considered information received in connection with the annual review, as well as information provided on an ongoing basis at their regularly scheduled board and committee meetings. INVESTMENT MANAGEMENT SERVICES.The nature of the investment management services provided is quite complex and allows fund shareholders access to professional money management, instant diversification of their investments within an asset class, the opportunity to easily diversify among asset classes, and liquidity. In evaluating investment performance, the board expects the advisor to manage the fund in accordance with its investment objectives and approved strategies. In providing these services, the advisor utilizes teams of investment professionals (portfolio managers, analysts, research assistants, and securities traders) who require extensive information technology, research, training, compliance and other systems to conduct their business. At each quarterly meeting the Directors review investment performance information for the fund, together with comparative information for appropriate bench- (continued) - ------ 29 Approval of Management Agreement for Capital Value marks and peer groups of funds managed similarly to the fund. The Directors also review detailed performance information during the 15(c) Process comparing the fund's performance with that of similar funds not managed by the advisor. If performance concerns are identified, the Directors discuss with the advisor the reasons for such results (e.g., market conditions, security selection) and any efforts being undertaken to improve performance. The fund's performance fell below the median for both the one and three year periods during part of the past year. The board discussed the fund's performance with the advisor and was satisfied with the efforts being undertaken by the advisor. SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a comprehensive package of transfer agency, shareholder, and other services. The Directors review reports and evaluations of such services at their regular quarterly meetings, including the annual meeting concerning contract review, and reports to the board. These reports include, but are not limited to, information regarding the operational efficiency and accuracy of the shareholder and transfer agency services provided, staffing levels, shareholder satisfaction (as measured by external as well as internal sources), technology support, new products and services offered to fund shareholders, securities trading activities, portfolio valuation services, auditing services, and legal and operational compliance activities. Certain aspects of shareholder and transfer agency service level efficiency and the quality of securities trading activities are measured by independent third party providers and are presented in comparison to other fund groups not managed by the advisor. COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor provides detailed information concerning its cost of providing various services to the fund, its profitability in managing the fund, its overall profitability, and its financial condition. The Directors have reviewed with the advisor the methodology used to prepare this financial information. This financial information regarding the advisor is considered in order to evaluate the advisor's financial condition, its ability to continue to provide services under the management agreement, and the reasonableness of the current management fee. ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment to providing quality services to shareholders and to conducting its business ethically. They noted that the advisor's practices generally meet or exceed industry best practices and that the advisor was not implicated in the industry scandals of 2003 and 2004. ECONOMIES OF SCALE. The Directors review reports provided by the advisor on economies of scale for the complex as a whole and the year-over-year changes in revenue, costs, and profitability. The Directors concluded that economies of scale are difficult to measure and predict with precision, especially on a fund-by-fund basis. This analysis is also complicated by the additional services and content provided by the advisor and its reinves- (continued) - ------ 30 Approval of Management Agreement for Capital Value ment in its ability to provide and expand those services. Accordingly, the Directors also seek to evaluate economies of scale by reviewing other information, such as year-over-year profitability of the advisor generally, the profitability of its management of the fund specifically, the expenses incurred by the advisor in providing various functions to the fund, and the breakpoint fees of competitive funds not managed by the advisor. The Directors believe the advisor is appropriately sharing economies of scale through its competitive fee structure, fee breakpoints as the fund increases in size, and through reinvestment in its business to provide shareholders additional content and services. COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single, all-inclusive (or unified) management fee for providing all services necessary for the management and operation of the fund, other than brokerage expenses, taxes, interest, extraordinary expenses, and the fees and expenses of the fund's independent directors (including their independent legal counsel). Under the unified fee structure, the advisor is responsible for providing all investment advisory, custody, audit, administrative, compliance, recordkeeping, marketing and shareholder services, or arranging and supervising third parties to provide such services. By contrast, most other funds are charged a variety of fees, including an investment advisory fee, a transfer agency fee, an administrative fee, distribution charges and other expenses. Other than their investment advisory fees and Rule 12b-1 distribution fees, all other components of the total fees charged by these other funds may be increased without shareholder approval. The board believes the unified fee structure is a benefit to fund shareholders because it clearly discloses to shareholders the cost of owning fund shares, and, since the unified fee cannot be increased without a vote of fund shareholders, it shifts to the advisor the risk of increased costs of operating the fund and provides a direct incentive to minimize administrative inefficiencies. Part of the Directors' analysis of fee levels involves reviewing certain evaluative data compiled by a 15(c) Provider comparing the fund's unified fee to the total expense ratio of other funds in the fund's peer group. The unified fee charged to shareholders of the fund was at the median of the total expense ratios of its peer group. COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The Directors also requested and received information from the advisor concerning the nature of the services, fees, and profitability of its advisory services to advisory clients other than the fund. They observed that these varying types of client accounts require different services and involve different regulatory and entrepreneurial risks than the management of the fund. The Directors analyzed this information and concluded that the fees charged and services provided to the fund were reasonable by comparison. COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information from the advisor concerning collateral benefits it receives as a result of its relationship with the fund. They (continued) - ------ 31 Approval of Management Agreement for Capital Value concluded that the advisor's primary business is managing mutual funds and it generally does not use the fund or shareholder information to generate profits in other lines of business, and therefore does not derive any significant collateral benefits from them. The Directors noted that the advisor receives proprietary research from broker dealers that execute fund portfolio transactions and concluded that this research is likely to benefit fund shareholders. The Directors also determined that the advisor is able to provide investment management services to certain clients other than the fund, at least in part, due to its existing infrastructure built to serve the fund complex. The Directors concluded, however, that the assets of those other clients are not material to the analysis and, in any event, are included with the assets of the fund to determine breakpoints in the fund's fee schedule, provided they are managed using the same investment team and strategy. CONCLUSIONS OF THE DIRECTORS As a result of this process, the independent directors, in the absence of particular circumstances and assisted by the advice of legal counsel that is independent of the advisor, taking into account all of the factors discussed above and the information provided by the advisor concluded that the investment management agreement between the fund and the advisor is fair and reasonable in light of the services provided and should be renewed. - ------ 32 Share Class Information Three classes of shares are authorized for sale by the fund: Investor Class, Institutional Class, and Advisor Class. The total expense ratio of Institutional Class shares is lower than that of Investor Class shares. The total expense ratio of Advisor Class shares is higher than that of Investor Class shares. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. ADVISOR CLASS shares are sold primarily through institutions such as investment advisors, banks, broker-dealers, insurance companies, and financial advisors. Advisor Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. The total expense ratio of Advisor Class shares is 0.25% higher than the total expense ratio of Investor Class shares. All classes of shares represent a pro rata interest in the fund and generally have the same rights and preferences. - ------ 33 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective MODEST RALLY FOR STOCKS Cooling energy prices and a pause from the Federal Reserve enabled most U.S. stocks to post positive results from the March 31, 2006, date that American Century acquired the American Century-Mason Street funds' assets from Mason Street, to October 31, 2006. The stock market rallied after enduring a difficult spring--the broad S&P 500 Index fell by more than 4% during the last three weeks of May after unexpectedly high inflation figures led to concerns about rising interest rates. Stocks plodded along through the early summer, weighed down by uncertainties about inflation and economic growth, until the Federal Reserve chose to leave short-term interest rates unchanged at its policy meeting in mid-August. After 17 consecutive rate hikes over a two-year period, the Fed decided to stand pat amid evidence of moderating economic growth and declining energy and commodity prices. In response, the major stock indexes staged a strong rally that persisted through the end of the period. SIZE AND QUALITY MATTERED Thanks to the stock market's late-summer rally, most U.S. equity indexes advanced during the seven-month period. However, the market's overall gains masked some relatively narrow breadth. In an environment of slowing economic growth, investors focused their attention on the stocks of larger, higher-quality companies. Mid- and small-cap stocks lagged the performance of large-caps but still posted modest gains. Extending a multi-year trend, value shares performed better than growth stocks across the capitalization range. Unfortunately, the shares of mid- and small-cap growth stocks such as those in which the American Century-Mason Street Mid and Small Cap Growth funds invest produced negative returns for the seven months (see the table below). SECTOR PERFORMANCE SHIFTED Sector performance reflected the defensive, risk-averse posture of the market during the summer. Investors seeking companies with more predictable earnings and dividend payouts shifted money into utilities and telecommunication services providers, as well as companies that make everyday consumer products. On the downside, the information technology and health care sectors posted some of the largest declines during the period as investors moved away from the more speculative and growth-oriented segments of the market. The slowing economy also weighed on industrial and materials stocks, which are the most economically sensitive sectors.

By comparison, its benchmark, the Russell MidCap Growth Index, returned -0.16%. In a difficult environment for mid-cap growth stocks (see the Market Perspective on page 2) that saw many segments of the fund and benchmark produce negative returns, our positioning in the health care, industrials, energy, and consumer discretionary sectors detracted from performance on an absolute basis and relative to the benchmark. HEALTH CARE, INDUSTRIALS HURT Poor performance from our health care holdings was by far the largest detractor from relative and absolute results for the period. The portfolio's return was limited by our positioning and stock selection among medical device makers, biotechnology firms, and health care providers. The leading detractor in the health care space was biotech firm Neurocrine Biosciences. This portfolio overweight received an unfavorable FDA decision on its new sleep drug, hurting its share price. We eliminated this stock from the portfolio. In industrial shares, our stock selection limited returns, particularly among commercial services firms. Portfolio overweight positions such as Corporate Executive Board and Monster Worldwide, home of the monster.com job board, were key detractors during the period. After several years of solid performance, these stocks sold off in recent months on worries about slower economic growth, among other factors. Overall, the portfolio's industrial position returned -9%, while these stocks in the index returned -2%. ENERGY, CONSUMER DISCRETIONARY MIXED In the energy sector, our stock selection was a positive influence, though this sector detracted from relative performance because we were a little early taking profits from energy's big run-up in recent years. Stocks in the oil, gas, and consumable fuels industry were the sector's biggest detractors for the TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF % OF NET ASSETS NET ASSETS AS OF AS OF 10/31/06 4/30/06 - -------------------------------------------------------------------------------- Praxair, Inc. 2.5% 1.5% - -------------------------------------------------------------------------------- DaVita Inc. 2.4% 1.9% - -------------------------------------------------------------------------------- Amphenol Corp.

A Class shares are subject to a maximum sales charge of 5.75%. Had the sales charge been applied, returns would be lower than those shown. Total returns for periods less than one year are not annualized. (continued) - ------ 5 Mid Cap Growth - Portfolio Commentary period, led by CONSOL Energy. CONSOL is a leading coal and gas provider, which suffered from weaker energy prices and electricity demand. Nevertheless, one of the portfolio's top contributors to both relative and absolute results resided in the energy space--IntercontinentalExchange, an energy exchange benefiting from the intense volatility and trading activity in energy in recent months. Mixed returns were also the story among consumer discretionary shares, where positive contributions from many industries couldn't overcome poor performance by our hotel, restaurant, and leisure names. Some of the portfolio's biggest detractors from relative returns were in this industry segment, including Scientific Games, Station Casinos, and Choice Hotels International. On a positive note, one source of outperformance relative to our index was an underweight position in select consumer discretionary names where we saw business fundamentals deteriorating. A prime example is shares of homebuilders and home-related firms, as rising interest rates took a toll on many segments of the housing market. We had zero exposure to stocks in the household durables industry, which returned -15% for the period. In addition, this sector was home to top-ten contributor AnnTaylor Stores. This specialty retailer of women's apparel continued to benefit from management changes and a turnaround strategy enacted last year. PORTFOLIO OBJECTIVE & EXPECTATIONS American Century-Mason Street Mid Cap Growth seeks long-term growth and is committed to a strategy of identifying and investing in medium- and smaller-sized companies with above-average growth potential. Our disciplined investment process uses extensive research to identify companies that we believe are well managed, have solid growth in revenue and earnings, and have strong financial characteristics. We believe this investment approach can deliver solid performance over time, and that American Century-Mason Street Mid Cap Growth can be a good choice for the mid-cap growth portion of an investor's portfolio. In addition, the mid-cap space has historically offered above-average earnings growth, which should help drive relative performance.

By comparison, its benchmark, the small-cap Russell 2000 Growth Index, returned -2.98%. In a difficult environment for small-cap growth stocks (see the Market Perspective on page 2) that saw many segments of the fund and benchmark produce negative returns, our positioning in industrials and financials contributed positively to performance on an absolute basis and relative to the benchmark. That said, the portfolio's underperformance versus its index resulted in large part from disappointing stock selection in the health care, consumer discretionary, and energy sectors. HEALTH CARE HURT In the health care sector, we added value relative to the benchmark by underweighting biotechnology and pharmaceuticals, two poor-performing industry segments. In addition, this sector was home to one of the portfolio's biggest relative and absolute contributors--medical device-maker FoxHollow Technologies, which performed well on the strength of its solid product line and earnings growth, as well as a deal with pharmaceutical giant Merck. But despite those positives, many of the portfolio's leading relative and absolute detractors were health care providers, including LCA-Vision, The Providence Service Corp., Symbion, and Horizon Health. Add it all up, and the health care stocks in the portfolio returned -7%, compared with -4% for those in the index. CONSUMER DISCRETIONARY, ENERGY DETRACTED Mixed performance was also the story among consumer discretionary shares, where good stock picks among hotel, restaurant, and leisure names and auto parts providers couldn't overcome poor performance by our specialty retail stocks. One of the portfolio's biggest detractors resided in this space--Golf Galaxy. This golf retailer was hurt by bad weather and disappointing Father's Day sales, resulting in poor earnings. Another area where our stock selection worked against us was in energy, where TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF % OF NET ASSETS NET ASSETS AS OF AS OF 10/31/06 4/30/06 - -------------------------------------------------------------------------------- Kyphon Inc. 2.3% 1.4% - -------------------------------------------------------------------------------- Huron Consulting Group Inc. 2.2% 1.1% - -------------------------------------------------------------------------------- United Natural Foods Inc. 2.2% 1.7% - -------------------------------------------------------------------------------- Psychiatric Solutions, Inc. 2.1% 1.6% - -------------------------------------------------------------------------------- Advisory Board Co.

Total returns for periods less than one year are not annualized. Class returns would have been lower if fees had not been waived. (continued) - ------ 12 Small Cap Growth - Portfolio Commentary equipment & services holdings hurt, as did oil, gas & consumable fuels firms. For example, after a big run-up with energy prices in recent years, Hydril--an equipment & services firm with exposure to the volatile North American natural gas market--ended the seven-month reporting period as one of our biggest detractors. It's a similar story for James River Coal, where strong performance in 2005 turned negative in 2006. In part that's due to the fact that coal is seen as a cheaper alternative to natural gas, so when natural gas prices weaken, coal's pricing advantage decreases. INDUSTRIAL-STRENGTH GAINS The industrials sector was home to many of our leading contributors to performance. A good example is Corrections Corp. of America, which runs correctional facilities across the United States. This stock benefited from expanding business and a favorable municipal budget environment, making it the number-one contributor to both relative and absolute returns. Other leading contributors were business support outsourcing firm ICT Group, and the Huron Consulting Group. Huron is a financial consulting firm with expertise in issues around stock option grants and executive compensation--this during a period when several high-profile firms were hit with questions about the timing of option grants. We also added value relative to the index with an underweight position in information technology shares, which had negative absolute returns and made up the worst-performing segment of the index during the reporting period. The financials sector was another positive contributor as a result of our effective stock selection and allocation decisions in many industry segments. PORTFOLIO OBJECTIVE & EXPECTATIONS American Century-Mason Street Small Cap Growth seeks long-term growth by buying high-quality, fast-growing, small-cap companies. We believe that relative to small-cap value, growth currently offers greater opportunities through attractive relative value and strong earnings per share growth.

See Notes to Financial Statements. - ------ 15 Shareholder Fee Examples (Unaudited) Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006. ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 16 Shareholder Fee Examples (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD(1) ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO(1) - -------------------------------------------------------------------------------- MID CAP GROWTH SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- ACTUAL - -------------------------------------------------------------------------------- Investor Class $1,000 $927.20 $5.10 1.05% - -------------------------------------------------------------------------------- Institutional Class $1,000 $928.60 $4.13 0.85% - -------------------------------------------------------------------------------- A Class $1,000 $925.90 $6.31 1.30% - -------------------------------------------------------------------------------- B Class (after waiver)(2) $1,000 $923.40 $9.45 1.95% - -------------------------------------------------------------------------------- B Class (before waiver) $1,000 $923.40(3) $9.94 2.05% - -------------------------------------------------------------------------------- C Class $1,000 $922.50 $9.93 2.05% - -------------------------------------------------------------------------------- R Class $1,000 $924.50 $7.52 1.55% - -------------------------------------------------------------------------------- HYPOTHETICAL - -------------------------------------------------------------------------------- Investor Class $1,000 $1,019.91 $5.35 1.05% - -------------------------------------------------------------------------------- Institutional Class $1,000 $1,020.92 $4.33 0.85% - -------------------------------------------------------------------------------- A Class $1,000 $1,018.65 $6.61 1.30% - -------------------------------------------------------------------------------- B Class (after waiver)(2) $1,000 $1,015.38 $9.91 1.95% - -------------------------------------------------------------------------------- B Class (before waiver) $1,000 $1,014.87 $10.41 2.05% - -------------------------------------------------------------------------------- C Class $1,000 $1,014.87 $10.41 2.05% - -------------------------------------------------------------------------------- R Class $1,000 $1,017.39 $7.88 1.55% - -------------------------------------------------------------------------------- (1) Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period.

See Notes to Financial Statements. - ------ 23 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. American Century-Mason Street Mid Cap Growth Fund (Mid Cap Growth) and American Century-Mason Street Small Cap Growth Fund (Small Cap Growth) (the funds) are two funds in a series issued by the corporation (see Note 7). The funds are diversified under the 1940 Act. The funds' investment objective is to seek long-term capital growth. Mid Cap Growth invests primarily in stocks of mid-sized companies. Small Cap Growth invests primarily in stocks of smaller market capitalization companies. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- The funds are authorized to issue the Investor Class, the Institutional Class, the A Class, the B Class, the C Class and the R Class. The A Class may incur an initial sales charge. The A Class, B Class and C Class may be subject to a contingent deferred sales charge. The share classes differ principally in their respective sales charges and distribution and shareholder servicing expenses and arrangements. All shares of each fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the funds are allocated to each class of shares based on their relative net assets. Sale of the funds' Investor Class, Institutional Class, C Class and R Class commenced on April 3, 2006. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Debt securities maturing within 60 days may be valued at cost, plus or minus any amortization discount or premium. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the funds determine that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. FUTURES CONTRACTS -- The funds may enter into futures contracts in order to manage the funds' exposure to changes in market conditions. One of the risks of entering into futures contracts is the possibility that the change in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the funds are required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the funds. The variation margin is equal to the daily change in the contract value and is recorded as unrealized gains and losses. The funds recognize a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on futures transactions and unrealized appreciation (depreciation) on futures, respectively. REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (continued) - ------ 24 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. The fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable the fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to the fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the funds. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee) per class. The Agreement provides that all expenses of the funds, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of each specific class of shares of each fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in each fund's investment strategy (strategy assets) to calculate the appropriate fee rate for each fund. The strategy assets include each fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The annual management fee schedule for each class of Mid Cap Growth is as follows: - -------------------------------------------------------------------- INVESTOR, A, B, C & R INSTITUTIONAL - -------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------- First $500 million 1.05% 0.85% - -------------------------------------------------------------------- Over $500 million 1.00% 0.80% - -------------------------------------------------------------------- (continued) - ------ 25 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) The annual management fee schedule for each class of Small Cap Growth is as follows: - ------------------------------------------------------------------------ INVESTOR, A, B, C & R INSTITUTIONAL - ------------------------------------------------------------------------ STRATEGY ASSETS - ------------------------------------------------------------------------ First $1 billion 1.30% 1.10% - ------------------------------------------------------------------------ Over $1 billion 1.10% 0.90% - ------------------------------------------------------------------------ For the seven months ended October 31, 2006, the effective annual management fee for each class of each fund was as follows: - ------------------------------------------------------------------------ INVESTOR, A, B, C & R INSTITUTIONAL - ------------------------------------------------------------------------ Mid Cap Growth 1.05% 0.85% - ------------------------------------------------------------------------ Small Cap Growth 1.30% 1.10% - ------------------------------------------------------------------------ ACIM has entered into a Subadvisory Agreement with Mason Street Advisors LLC (Mason Street) on behalf of the funds. The subadvisor makes investment decisions for the funds in accordance with the funds' investment objectives, policies, and restrictions under the supervision of ACIM and the Board of Directors. ACIM pays all costs associated with retaining Mason Street as the subadvisor of the funds. DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class, B Class, C Class and R Class (collectively the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the B Class and C Class will pay American Century Investment Services, Inc. (ACIS) an annual distribution fee and service fee of 0.75% and 0.25%, respectively. The plans provide that the A Class and the R Class will pay ACIS an annual distribution and service fee of 0.25% for the A Class and 0.50% for the R Class. The fees are computed and accrued daily based on each class's daily net assets and paid monthly in arrears. The distribution fee provides compensation for expenses incurred in connection with distributing shares of the classes including, but not limited to, payments to brokers, dealers, and financial institutions that have entered into sales agreements with respect to shares of the funds. The service fee provides compensation for individual shareholder services rendered by broker/dealers or other independent financial intermediaries for A Class, B Class, C Class and R Class shares. ACIM has agreed to voluntarily waive a portion of its distribution and service fees through March 31, 2008, by 0.10% for the B Class of Mid Cap Growth and by 0.15% and 0.25% for the A Class and B Class of Small Cap Growth, respectively. The total amount of the waivers for the seven months ended October 31, 2006, was as follows: - ------------------------------------------------------------------------------- A B - ------------------------------------------------------------------------------- Mid Cap Growth -- $4,434 - ------------------------------------------------------------------------------- Small Cap Growth $40,555 $10,766 - ------------------------------------------------------------------------------- Fees incurred under the plans during the seven months ended October 31, 2006, are detailed in the Statement of Operations. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. JPMorgan Chase Bank is a custodian of the funds and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC.

Because of this, Small Cap Growth may be subject to greater risk and market fluctuations than a fund investing in larger, more established companies. 6. FEDERAL TAX INFORMATION On December 12, 2006, Mid Cap Growth and Small Cap Growth declared and paid a per-share distribution from net realized gains to shareholders of record on December 11, 2006 of $0.7567 and $0.9492, respectively, for each class of the funds. The tax character of distributions paid during the seven months ended October 31, 2006 and the years end March 31, 2006 and March 31, 2005 were as follows: - ------------------------------------------------------------------------------------------------------ MID CAP GROWTH SMALL CAP GROWTH - ------------------------------------------------------------------------------------------------------ OCT. 31, MARCH 31, MARCH 31, OCT. 31, MARCH 31, MARCH 31, 2006(1) 2006 2005 2006(1) 2006 2005 - ------------------------------------------------------------------------------------------------------ DISTRIBUTIONS PAID FROM - ------------------------------------------------------------------------------------------------------ Ordinary income -- -- -- -- $ 918,544 -- - ------------------------------------------------------------------------------------------------------ Long-term capital gains -- $16,709,379 -- -- $4,756,306 $1,684,232 - ------------------------------------------------------------------------------------------------------ (1) April 1, 2006 through October 31, 2006. The funds' fiscal year end was changed from March 31 to October 31 resulting in a seven-month annual reporting period. The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- MID CAP GROWTH SMALL CAP GROWTH - -------------------------------------------------------------------------------- Federal tax cost of investments $159,080,621 $42,239,108 ================================================================================ Gross tax appreciation of investments $25,494,185 $8,268,769 - ---------------------------------------- Gross tax depreciation of investments (2,556,382) (511,702) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $22,937,803 $7,757,067 ================================================================================ Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies -- -- - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $22,937,803 $7,757,067 ================================================================================ Undistributed ordinary income $2,253,852 -- - ---------------------------------------- Accumulated long-term gains $7,757,181 $2,958,172 - ---------------------------------------- Accumulated capital losses $(1,141,452) $(1,162,699) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future capital gains for federal income tax purposes. The capital loss carryovers for the funds expire in 2014. (continued) - ------ 29 Notes to Financial Statements OCTOBER 31, 2006 7. REORGANIZATION PLAN As of the close of business on March 31, 2006, Mid Cap Growth and Small Cap Growth acquired all of the net assets of two funds issued by Mason Street Funds, Inc., Mason Street Aggressive Growth Stock Fund (Aggressive Growth Stock) and Mason Street Small Cap Growth Stock Fund (Small Cap Growth Stock), respectively, pursuant to a plan of reorganization approved by the acquired funds' shareholders on March 15, 2006 for Aggressive Growth Stock and March 23, 2006 for Small Cap Growth Stock. The surviving funds for the purposes of maintaining the financial statements and performance history in the post-reorganization are Aggressive Growth Stock and Small Cap Growth Stock. These funds were also reorganized as funds issued by American Century Mutual Funds, Inc. The funds' fiscal year end was changed from March 31 to October 31. Prior to the reorganization, Aggressive Growth Stock and Small Cap Growth Stock had A Class, B Class and C Class shares. At the close of business and as a result of the reorganization, A Class shares and B Class shares of the acquired funds were converted to A Class shares and B Class shares, respectively, of the surviving funds. C Class shares of the acquired funds were converted to A Class shares of the surviving funds. A Class, B Class and C Class net assets of Aggressive Growth Stock before the reorganization were $193,018,755, $9,032,496 and $1,010,558, respectively. Immediately after the reorganization, A Class, B Class and C Class net assets of Mid Cap Growth were $194,029,313, $9,032,496 and $-, respectively. A Class, B Class and C Class net assets of Small Cap Growth Stock before the reorganization were $55,084,794, $8,283,664 and $1,719,620, respectively. Immediately after the reorganization, A Class, B Class and C Class net assets of Small Cap Growth were $56,804,414, $8,283,664 and $-, respectively. 8. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. - ------ 30 Mid Cap Growth - Financial Highlights For a Share Outstanding Throughout the Period Indicated - -------------------------------------------------------------------------------- INVESTOR CLASS - -------------------------------------------------------------------------------- 2006(1) - -------------------------------------------------------------------------------- PER-SHARE DATA - -------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $14.78 - -------------------------------------------------------------------------------- Income From Investment Operations - ------------------------------------------------------------ Net Investment Income (Loss)(2) (0.01) - ------------------------------------------------------------ Net Realized and Unrealized Gain (Loss) (1.01) - -------------------------------------------------------------------------------- Total From Investment Operations (1.02) - -------------------------------------------------------------------------------- Net Asset Value, End of Period $13.76 ================================================================================ TOTAL RETURN(3) (6.90)% - -------------------------------------------------------------------------------- RATIOS/SUPPLEMENTAL DATA - -------------------------------------------------------------------------------- Ratio of Operating Expenses to Average Net Assets 1.05%(4) - ------------------------------------------------------------ Ratio of Net Investment Income (Loss) to Average Net Assets (0.19)%(4) - ------------------------------------------------------------ Portfolio Turnover Rate 52% - ------------------------------------------------------------ Net Assets, End of Period (in thousands) $311 - -------------------------------------------------------------------------------- (1) April 3, 2006 (commencement of sale) through October 31, 2006.

See Notes to Financial Statements. - ------ 42 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of American Century-Mason Street Mid Cap Growth Fund and American Century-Mason Street Small Cap Growth Fund (collectively the "Funds"), two of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statements of operations and the statements of changes in net assets for the seven month period then ended, and the financial highlights for the periods ended October 31, 2006 (except as noted below). These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. The financial statements and financial highlights for each of the periods ended March 31, 2006 and prior were audited by other auditors whose report, dated May 1, 2006, expressed an unqualified opinion on those financial statements and financial highlights. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such fiscal October 31, 2006 financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds as of October 31, 2006, the results of their operations and the changes in their net assets for the seven month period then ended, and the financial highlights for the periods ended October 31, 2006, in conformity with accounting principles generally accepted in the United States of America.

Each director serves until his or her successor is duly elected and qualified or until he or she retires. Mandatory retirement age for independent directors is 72.

The total expense ratio of Institutional Class shares is lower than that of Investor Class shares. The total expense ratios of A Class, B Class, C Class and R Class shares are higher than that of Investor Class shares. The funds are available for purchase only through financial intermediaries by investors who seek advice from them. The funds are closed to other investors, but those with open accounts may make additional investments and reinvest dividends and capital gains distributions as long as such accounts remain open. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; or 2) through certain financial intermediaries (such as banks, broker-dealers, insurance companies and investment advisors), which may require payment of a transaction fee to the financial intermediary. INSTITUTIONAL CLASS shares are available to large investors such as endowments, foundations, and retirement plans, and to financial intermediaries serving these investors. This class recognizes the relatively lower cost of serving institutional customers and others who invest at least $5 million ($3 million for endowments and foundations) in an American Century fund or at least $10 million in multiple funds. In recognition of the larger investments and account balances and comparatively lower transaction costs, the unified management fee of Institutional Class shares is 0.20% less than the unified management fee of Investor Class shares. A CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. A Class shares are sold at their offering price, which is net asset value plus an initial sales charge that ranges from 5.75% to 0.00% for equity funds, depending on the amount invested. The initial sales charge is deducted from the purchase amount before it is invested. A Class shares may be subject to a contingent deferred sales charge (CDSC). There is no CDSC on shares acquired through reinvestment of dividends or capital gains. The prospectus contains information regarding reductions and waivers of sales charges for A Class shares. The unified management fee for A Class shares is the same as for Investor Class shares. A Class shares also are subject to a 0.25% annual Rule 12b-1 distribution and service fee. B CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. B Class shares redeemed within six years of purchase are subject to a CDSC that declines from 5.00% during the first year after purchase to 0.00% after the sixth year. There is no CDSC on shares acquired through reinvestment of dividends or capital gains. The unified management fee for B Class shares is the same as for Investor Class shares. B Class shares also are subject to a 1.00% annual Rule 12b-1 distribution and service fee. B Class shares automatically convert to A Class shares (with lower expenses) eight years after their purchase date. (continued) - ------ 47 Share Class Information C CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. C Class shares redeemed within 12 months of purchase are subject to a CDSC of 1.00%. There is no CDSC on shares acquired through reinvestment of dividends or capital gains. The unified management fee for C Class shares is the same as for Investor Class shares. C Class shares also are subject to a Rule 12b-1 distribution and service fee of 1.00%. R CLASS shares are sold primarily through employer-sponsored retirement plans and through institutions such as investment advisors, banks, broker-dealers, and insurance companies. The unified management fee for R Class shares is the same as for Investor Class shares. R Class shares are subject to a 0.50% annual Rule 12b-1 distribution and service fee. All classes of shares represent a pro rata interest in the funds and generally have the same rights and preferences. - ------ 48 Additional Information RETIREMENT ACCOUNT INFORMATION As required by law, any distributions you receive from an IRA or certain 403(b), 457 and qualified plans [those not eligible for rollover to an IRA or to another qualified plan] are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.

Market Perspective [photo of Mark Mallon] BY MARK MALLON, CHIEF INVESTMENT OFFICER, AMERICAN CENTURY INVESTMENTS STOCKS RALLIED AS FED PAUSED Cooling energy prices and a pause from the Federal Reserve enabled U.S. stocks to post positive results in the period from May 12, 2006, through October 31, 2006. The stock market rallied after enduring a difficult spring -- the S&P 500 Index fell by more than 4% during the last three weeks of May after unexpectedly high inflation figures led to concerns about rising interest rates. Stocks plodded along through early summer, weighed down by uncertainties about inflation and economic growth until the Federal Reserve chose to leave short-term interest rates unchanged at its policy meeting in mid-August. After 17 consecutive rate hikes over a two-year period, the Fed decided to stand pat amid evidence of moderating economic growth and declining energy and commodity prices. In response, the major stock indexes staged a rally that persisted through the end of the period. SIZE AND QUALITY MATTERED Thanks to the stock market's late-summer rally, the broad equity indexes advanced 5-7% during the period. However, the market's overall gains masked some relatively narrow breadth. In an environment of slowing economic growth, investors focused their attention on the stocks of larger, higher-quality companies, such as those that make up the S&P 500. Mid- and small-cap stocks lagged the performance of large-caps but still posted gains of 1-2%. Extending a multi-year trend, value shares performed better than growth stocks across the capitalization range. SECTOR PERFORMANCE SHIFTED Sector performance reflected the defensive, risk-averse posture of the market during the summer. Investors seeking companies with more predictable earnings and dividend payouts shifted money into utilities and telecommunication services providers, as well as companies that make everyday consumer products. Meanwhile, the market shifted away from the industrials and materials sectors, economically-sensitive sectors that surged with the broader economy in early 2006 but suffered as economic growth slowed in the second and third quarters.

This portfolio is one of nine new NT tracker funds available exclusively in LIVESTRONG Portfolios from American Century Investments. NT is an acronym for "No Tobacco." American Century Investments introduced LIVESTRONG Portfolios on May 12, 2006, as part of a strategic collaboration with Lance Armstrong and the Lance Armstrong Foundation (LAF).** On an absolute basis, NT Growth received significant contributions to return from the information technology, health care, consumer discretionary, and financials sectors; energy, materials, and industrials were only slight detractors. Relative to its benchmark, NT Growth's outperformance resulted largely from effective stock selection across a wide range of sectors, led by consumer discretionary, health care, and industrials, among others. The portfolio's positioning detracted from performance in only two main areas--consumer staples on the one hand, and utilities on the other, a tiny segment (less than 1%) of the fund and index. TOP CONTRIBUTORS Stock selection added value in consumer discretionary shares, particularly among specialty retail names such as Home Depot and Lowe's (underweights), as well as Foot Locker, Payless Shoesource, and Gap (overweights). NT Growth's holdings in this industry were up 10%, versus 2% for the index's specialty retail shares. The portfolio's consumer discretionary holdings returned 11%, compared with 6% for this segment of the index. Some of the leading contributors in the consumer discretionary sector were Polo Ralph Lauren and JC Penney. Polo announced better-than-expected earnings and operating margin figures, as well as a share buyback plan. JC Penney continued to benefit from a decision to close underperforming stores. The firm announced better-than-expected same-store sales figures, as well as rapid growth in Internet sales, and lifted its earnings guidance. NT Growth benefited from good stock selection in health care, home to several of the portfolio's leading contributors to relative results. Though NT Growth was slightly underweight in this sector, the TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF NET ASSETS AS OF 10/31/06 - -------------------------------------------------------------------------------- Bank of America Corp. 3.3% - -------------------------------------------------------------------------------- Cisco Systems Inc. 3.0% - -------------------------------------------------------------------------------- Intel Corp. 2.7% - -------------------------------------------------------------------------------- PepsiCo, Inc. 2.7% - -------------------------------------------------------------------------------- Oracle Corp. 2.6% - -------------------------------------------------------------------------------- Google Inc.

(continued) - ------ 4 NT Growth - Portfolio Commentary health care names in the portfolio were up 12% during the quarter, compared with 9% for those in the index. The leading contributor to both relative and absolute performance in this space was Baxter International, which performed well thanks to progress on an ongoing turnaround under new management. Effective stock selection also helped NT Growth's relative return in industrials, where we favored stocks of companies that typically perform better late in economic cycles and that have less interest rate sensitivity, such as capital goods and aerospace and defense firms. Continental Airlines was among the portfolio's biggest contributors to both relative and absolute returns. The company is experiencing good yield and traffic trends, and has a relatively young, efficient fleet of planes. Finally, our top contributor during the period was an overweight position in Freescale Semiconductor, a spin-off from Motorola producing chips for a number of wireless and industrial applications. Freescale performed well overall, and received an additional boost near the end of the period after agreeing to be acquired at a significant premium to its existing share price. CONSUMER STAPLES DETRACTED The portfolio's performance would have been even better relative to its benchmark but for positioning among consumer staples shares. We were underweight this sector, which was among the better-performing segments of the market during the period. Disappointing stock selection also limited NT Growth's relative return. In particular, positioning among food & staples retailing shares--the leading consumer staples industry contributor to index returns--detracted from relative performance. PORTFOLIO OBJECTIVE & EXPECTATIONS NT Growth seeks long-term capital appreciation. We pursue our objective by continuing to remain fully invested in large companies that are exhibiting sustainable improvement in their businesses. It is our belief that owning such companies will generate outperformance over time versus the Russell 1000 Growth Index.

Its benchmark, the Russell Midcap Growth Index, returned 0.79% in the same time period. This portfolio is one of nine new NT tracker funds available exclusively in LIVESTRONG Portfolios from American Century Investments. NT is an acronym for "No Tobacco." American Century Investments introduced LIVESTRONG Portfolios on May 12, 2006, as part of a strategic collaboration with Lance Armstrong and the Lance Armstrong Foundation (LAF).** NT Vista struggled on both an absolute and relative basis after the U.S. stock market declined in May 2006. The broad market rebounded late in the reporting period after the Federal Reserve paused its two-year, interest rate-hike campaign in August. But the portfolio missed the rebound's gains. That's because the market's favor swung toward consumer-oriented and technology stocks, and our picks in those sectors did not perform well. Our underweight positions in energy, health care and consumer discretionary further detracted from absolute and relative performance. SECURITY SELECTION REDUCED RETURNS Several of the portfolio's leading detractors were stocks in the industrials and materials sectors, which had performed well in early 2006. These stocks fit the portfolio's focus on companies that appeared poised to benefit from a rebound in capital spending. Those companies included Titanium Metals, a maker of titanium materials used in the aircraft industry. Its shares declined 27% in the reporting period after surging 181% between Jan. 1, 2006, and the beginning of the reporting period. Likewise, shares of TETRA Technologies, which caps old offshore wells and either repairs or deconstructs broken offshore energy platforms, declined 8% in the reporting period after rising 96% between the start of 2006 and the beginning of the reporting period. It represented one of the portfolio's biggest overweight positions. Fitting its portfolio process of shedding investments that lose share-price momentum, NT Vista reduced its stake in both companies, along with its overall stakes in industrials and mate- TOP TEN HOLDINGS AS OF OCTOBER 31, 2006 - -------------------------------------------------------------------------------- % OF NET ASSETS AS OF 10/31/06 - -------------------------------------------------------------------------------- NII Holdings, Inc.

Similarly, NT Vista substantially reduced its stake in its worst individual performer, MEMC Electronic Materials, which lost 20% of its value in the reporting period after soaring 120% the previous six months. Our health care sector return for the period also detracted from performance. The portfolio's underperformance reflected an underweight stake in the pharmaceutical industry, which recovered nicely after a sluggish start to 2006. It also reflected an underweight stake in health care providers and services; again, shares in that industry stabilized after a tough start to 2006. TELECOM PROVIDED POSITIVE CONTRIBUTIONS Telecommunications was the only sector that boosted NT Vista's relative performance. The portfolio's entire stake in the sector centered on the wireless industry, including positions in two cellular providers, NII Holdings and America Movil SA de CV, focused on the Latin American market. Both stocks ranked among the portfolio's top five positions in the period, and they also ranked among its 10 leading individual contributors on both a relative- and total-return basis. Thermo Electron Corp. topped the portfolio's list of leading individual contributors. Shares in this manufacturer of analytical instruments for medical and other research applications, which announced plans to merge with Fisher Scientific, rose steadily during the period. The portfolio steadily raised its stake in the company as its value increased. PORTFOLIO OBJECTIVE & EXPECTATIONS NT Vista adheres to an investment process that identifies mid-sized and smaller companies with accelerating earnings and revenue. Ultimately, we believe this selection strategy will produce solid, long-term gains for investors. It's difficult to gauge long-term performance based on short-term returns, such as those from this reporting period, which can be extremely volatile. We think the portfolio will perform well in a consistent, directional market, and we're encouraged by the market's behavior since the Fed paused its interest-rate hike campaign in August. Growth stocks traditionally have performed well after the Fed stops raising rates, and we believe our process works well in such an environment.

This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from May 1, 2006 to October 31, 2006 (except as noted). ACTUAL EXPENSES The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. If you hold Investor Class shares of any American Century fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century account (i.e., not a financial intermediary or retirement plan account), American Century may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered under your Social Security number. PERSONAL ACCOUNTS include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Brokerage accounts, you are currently not subject to this fee. We will not charge the fee as long as you choose to manage your accounts exclusively online. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund's share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. (continued) - ------ 15 Shareholder Fee Examples (Unaudited) Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher. - -------------------------------------------------------------------------------- EXPENSES PAID BEGINNING ENDING DURING PERIOD(1) ANNUALIZED ACCOUNT VALUE ACCOUNT VALUE 5/1/06 - EXPENSE 5/1/06 10/31/06 10/31/06 RATIO(1) - -------------------------------------------------------------------------------- NT GROWTH -- INSTITUTIONAL CLASS SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- Actual $1,000 $1,057.00(2) $3.88(3) 0.80% - -------------------------------------------------------------------------------- Hypothetical $1,000 $1,021.17(4) $4.08(4) 0.80% - -------------------------------------------------------------------------------- NT VISTA -- INSTITUTIONAL CLASS SHAREHOLDER FEE EXAMPLE - -------------------------------------------------------------------------------- Actual $1,000 $900.00(2) $3.58(3) 0.80% - -------------------------------------------------------------------------------- Hypothetical $1,000 $1,021.17(4) $4.08(4) 0.80% - -------------------------------------------------------------------------------- (1) Expenses are equal to the class's annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period.

See Notes to Financial Statements. - ------ 19 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. NT Growth Fund (NT Growth) and NT Vista Fund (NT Vista) (collectively, the funds) are two funds in a series issued by the corporation. The funds are diversified under the 1940 Act. The funds' investment objective is to seek long-term capital growth. The funds pursue this objective by investing primarily in equity securities. NT Growth generally invests in larger companies but may purchase companies of any size. NT Vista generally invests in companies that are medium-sized and smaller at the time of purchase. The funds are not permitted to invest in any securities issued by companies assigned the Global Industry Classification Standard for the tobacco industry. The funds incepted on May 12, 2006. The following is a summary of the funds' significant accounting policies. SECURITY VALUATIONS -- Securities traded primarily on a principal securities exchange are valued at the last reported sales price, or at the mean of the latest bid and asked prices where no last sales price is available. Depending on local convention or regulation, securities traded over-the-counter are valued at the mean of the latest bid and asked prices, the last sales price, or the official close price. Debt securities not traded on a principal securities exchange are valued through a commercial pricing service or at the mean of the most recent bid and asked prices. Discount notes may be valued through a commercial pricing service or at amortized cost, which approximates fair value. Securities traded on foreign securities exchanges and over-the-counter markets are normally completed before the close of business on days that the New York Stock Exchange (the Exchange) is open and may also take place on days when the Exchange is not open. If an event occurs 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, that security would be valued at fair value as determined in accordance with procedures adopted by the Board of Directors. If the funds determine that the market price of 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 by, or in accordance with procedures adopted by, the Board of Directors or its designee if such fair value determination would materially impact a fund's net asset value. Certain other circumstances that may cause the funds to fair value a security such as: a security has been declared in default; trading in a security has been halted during the trading day; or there is a foreign market holiday and no trading will commence. SECURITY TRANSACTIONS -- Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes. INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is recorded as of the ex-dividend date. Distributions received on securities that represent a return of capital or capital gain are recorded as a reduction of cost of investments and/or as a realized gain. The funds estimate the components of distributions received that may be considered nontaxable distributions or capital gain distributions for income tax purposes. Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums. FOREIGN CURRENCY TRANSACTIONS -- All assets and liabilities initially expressed in foreign currencies are translated into U.S. dollars at prevailing exchange rates at period end. Purchases and sales of investment securities, dividend and interest income, and certain expenses are translated at the rates of exchange prevailing on the respective dates of such transactions. For assets and liabilities, other than investments in securities, net realized and unrealized gains and losses from foreign currency translations arise from changes in currency exchange rates. Net realized and unrealized foreign currency exchange gains or losses occurring during the holding period of investment securities are a component of realized gain (loss) on investment transactions and unrealized appreciation (depreciation) on investments, respectively. Certain countries may impose taxes on the contract amount of purchases and sales of foreign currency contracts in their currency. The funds record the foreign tax expense, if any, as a reduction to the net realized gain (loss) on foreign currency transactions. FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS -- The funds may enter into forward foreign currency exchange contracts to facilitate transactions of securities denominated in a foreign currency or to hedge the funds' exposure to foreign currency exchange rate fluctuations. The net U.S. dollar value of foreign currency underlying all contractual commitments held by the funds and the resulting unrealized appreciation or depreciation are determined daily using prevailing exchange rates. The funds bear the risk of an unfavorable change in the foreign currency exchange rate underlying the forward contract. Additionally, losses may arise if the counterparties do not perform under the contract terms. (continued) - ------ 20 Notes to Financial Statements OCTOBER 31, 2006 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED) REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) (the investment advisor) has determined are creditworthy pursuant to criteria adopted by the Board of Directors. Each repurchase agreement is recorded at cost. Each fund requires that the collateral, represented by securities, received in a repurchase transaction be transferred to the custodian in a manner sufficient to enable each fund to obtain those securities in the event of a default under the repurchase agreement. ACIM monitors, on a daily basis, the securities transferred to ensure the value, including accrued interest, of the securities under each repurchase agreement is equal to or greater than amounts owed to each fund under each repurchase agreement. JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, each fund, along with other registered investment companies having management agreements with ACIM or American Century Global Investment Management, Inc. (ACGIM), may transfer uninvested cash balances into a joint trading account. These balances are invested in one or more repurchase agreements that are collateralized by U.S. Treasury or Agency obligations. INCOME TAX STATUS -- It is each fund's policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. Accordingly, no provision has been made for federal or state income taxes. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income and net realized gains, if any, are generally declared and paid annually. INDEMNIFICATIONS -- Under the corporation's organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the funds. The risk of material loss from such claims is considered by management to be remote. USE OF ESTIMATES -- The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates. 2. FEES AND TRANSACTIONS WITH RELATED PARTIES MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM, under which ACIM provides the funds with investment advisory and management services in exchange for a single, unified management fee (the fee). The Agreement provides that all expenses of the funds, except brokerage commissions, taxes, interest, fees and expenses of those directors who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is computed and accrued daily based on the daily net assets of each fund and paid monthly in arrears. For funds with a stepped fee schedule, the rate of the fee is determined by applying a fee rate calculation formula. This formula takes into account all of the investment advisor's assets under management in each fund's investment strategy (strategy assets) to calculate the appropriate fee rate for each fund. The strategy assets include each fund's assets and the assets of other clients of the investment advisor that are not in the American Century family of funds, but that have the same investment team and investment strategy. The strategy assets of NT Growth include the assets of Growth Fund, one fund in a series issued by the corporation. The annual management fee for NT Vista is 0.80%. (continued) - ------ 21 Notes to Financial Statements OCTOBER 31, 2006 2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED) The annual management fee schedule for NT Growth is as follows: - -------------------------------------------------------------------------------- INSTITUTIONAL - -------------------------------------------------------------------------------- STRATEGY ASSETS - -------------------------------------------------------------------------------- First $5 billion 0.800% - -------------------------------------------------------------------------------- Next $5 billion 0.780% - -------------------------------------------------------------------------------- Next $5 billion 0.770% - -------------------------------------------------------------------------------- Next $5 billion 0.760% - -------------------------------------------------------------------------------- Next $5 billion 0.750% - -------------------------------------------------------------------------------- Next $5 billion 0.700% - -------------------------------------------------------------------------------- Over $30 billion 0.600% - -------------------------------------------------------------------------------- The effective annual management fee for NT Growth for the period May 12, 2006 (fund inception) through October 31, 2006 was 0.80%. RELATED PARTIES -- Certain officers and directors of the corporation are also officers and/or directors, and, as a group, controlling stockholders of American Century Companies, Inc. (ACC), the parent of the corporation's investment advisor, ACIM, the distributor of the corporation, American Century Investment Services, Inc., and the corporation's transfer agent, American Century Services, LLC. The funds are wholly owned by American Century Assets Allocation Portfolios, Inc. (ACAAP). ACAAP does not invest in the funds for the purpose of exercising management or control. JPMorgan Chase Bank is a custodian of the funds and a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. 3. INVESTMENT TRANSACTIONS Investment transactions, excluding short-term investments, for the period May 12, 2006 (fund inception) through October 31, 2006, were as follows: - -------------------------------------------------------------------------------- NT GROWTH NT VISTA - -------------------------------------------------------------------------------- Purchases $82,305,327 $48,554,334 - -------------------------------------------------------------------------------- Proceeds from sales $26,863,963 $22,357,782 - -------------------------------------------------------------------------------- For the period May 12, 2006 (fund inception) through October 31, 2006, NT Vista incurred a purchase in kind of equity securities valued at $18,446,064. A purchase in kind occurs when a fund receives securities into its portfolio in lieu of cash as payment from a purchasing shareholder. (continued) - ------ 22 Notes to Financial Statements OCTOBER 31, 2006 4. FEDERAL TAX INFORMATION The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements. There were no distributions paid by the funds during the period May 12, 2006 (fund inception) through October 31, 2006. As of October 31, 2006, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: - -------------------------------------------------------------------------------- NT GROWTH NT VISTA - -------------------------------------------------------------------------------- Federal tax cost of investments $55,268,636 $24,148,673 ================================================================================ Gross tax appreciation of investments $4,622,074 $1,827,745 - --------------------------------------------------- Gross tax depreciation of investments (428,092) (319,891) - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) of investments $4,193,982 $1,507,854 ================================================================================ Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies (1,063) -- - -------------------------------------------------------------------------------- Net tax appreciation (depreciation) $4,192,919 $1,507,854 ================================================================================ Undistributed ordinary income $109,137 -- - --------------------------------------------------- Accumulated capital losses $(965,439) $(3,142,236) - -------------------------------------------------------------------------------- The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on certain forward foreign currency exchange contracts. The accumulated capital losses listed above represent net capital loss carryovers that may be used to offset future realized capital gains for federal income tax purposes. The capital loss carryovers for the funds expire in 2014. 5. RECENTLY ISSUED ACCOUNTING STANDARDS In June 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether an entity is taxable in a particular jurisdiction), and requires certain expanded tax disclosures. FIN 48 is effective for fiscal years beginning after December 15, 2006, and is to be applied to all open tax years as of the date of effectiveness. The FASB issued Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" (FAS 157), in September 2006, which is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands the required financial statement disclosures about fair value measurements. Management is currently evaluating the impact of adopting FIN 48 and FAS 157. - ------ 23 NT Growth - Financial Highlights For a Share Outstanding Throughout the Period Indicated - -------------------------------------------------------------------------------- INSTITUTIONAL CLASS - -------------------------------------------------------------------------------- 2006(1) - -------------------------------------------------------------------------------- PER-SHARE DATA - -------------------------------------------------------------------------------- Net Asset Value, Beginning of Period $10.00 - -------------------------------------------------------------------------------- Income From Investment Operations - -------------------------------------------------------------- Net Investment Income (Loss) 0.01 - -------------------------------------------------------------- Net Realized and Unrealized Gain (Loss) 0.56 - -------------------------------------------------------------------------------- Total From Investment Operations 0.57 - -------------------------------------------------------------------------------- Net Asset Value, End of Period $10.57 ================================================================================ TOTAL RETURN(2) 5.70% - -------------------------------------------------------------------------------- RATIOS/SUPPLEMENTAL DATA - -------------------------------------------------------------------------------- Ratio of Operating Expenses to Average Net Assets 0.80%(3) - -------------------------------------------------------------- Ratio of Net Investment Income (Loss) to Average Net Assets 0.36%(3) - -------------------------------------------------------------- Portfolio Turnover Rate 57% - -------------------------------------------------------------- Net Assets, End of Period (in thousands) $58,983 - -------------------------------------------------------------------------------- (1) May 12, 2006 (fund inception) through October 31, 2006.

See Notes to Financial Statements. - ------ 25 Report of Independent Registered Public Accounting Firm The Board of Directors and Shareholders, American Century Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of NT Growth Fund and NT Vista Fund (collectively the "Funds"), two of the mutual funds comprising American Century Mutual Funds, Inc., as of October 31, 2006, and the related statements of operations, the statements of changes in net assets, and the financial highlights for the period May 12, 2006 (Funds' inception) to October 31, 2006. These financial statements and financial highlights are the responsibility of the Funds' management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Funds are not required to have, nor were we engaged to perform, an audit of their internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds' internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of October 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds, as of October 31, 2006, and the results of their operations, the changes in their net assets, and the financial highlights for the period May 12, 2006 (Funds' inception) to October 31, 2006, in conformity with accounting principles generally accepted in the United States of America.

Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld. If you don't want us to withhold on this amount, you must notify us to not withhold the federal income tax. Even if you plan to roll over the amount you withdraw to another tax-deferred account, the withholding rate still applies to the withdrawn amount unless we have received notice not to withhold federal income tax prior to the withdrawal. You may notify us in writing or in certain situations by telephone or through other electronic means. You have the right to revoke your withholding election at any time and any election you make may remain in effect until revoked by filing a new election. Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don't have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld. State taxes will be withheld from your distribution in accordance with the respective state rules.
