To help you monitor your investment, my colleagues and I take pride in providing you with the annual report for the American Century® International Growth, Global Growth, Emerging Markets, and International Value funds for the 12 months ended November 30, 2007. I am honored to be addressing you in the "Our Message" space long devoted to company founder Jim Stowers, Jr. and his son Jim Stowers III. Jim Stowers III stepped down from the American Century Companies, Inc. (ACC) board of directors in July 2007, his final step in a well-planned career transition to pursue new ventures outside the company. This reflected his family's support of our company's direction and its leadership team. The Stowers family remains an integral part of our heritage, leadership, and financial structure. In fact, Jim Stowers, Jr. continues as co-chair of the ACC board with Richard Brown, who has been on the board since 1998. American Century Investments, our clients, and our employees have been my top priority since I became company president and CEO in March, 2007. We have also added the executive talents of overall chief investment officer (CIO) Enrique Chang, international equity CIO Mark On, U.S. growth equity CIO Steve Lurito, and chief operating officer Barry Fink. This skilled group, combined with our existing senior management team, has already had a positive impact on the development and management of the products and services we take pride in delivering to you. We believe the ultimate measure of our performance is our clients' success. Therefore, our focus continues to be on building a long-term relationship with you and on delivering superior investment performance across our product line. /s/Jonathan Thomas [photo of James E.

MARKET PERSPECTIVE [photo of chief investment officer] By Mark On, Chief Investment Officer, International Equity INTERNATIONAL STOCKS SHOWED ROBUST GAINS A strong global economy combined with relatively tame inflation and healthy labor markets helped promote stellar stock gains for the 12 months ended November 30, 2007. Among the developed markets, Europe fared well, with the strongest returns coming from the euro-zone nations. In contrast, performance was flat in Japan, as weak consumer spending, a challenging political climate, and slowing demand from the United States pressured Japan's stocks. Emerging markets remained the world's standout performers, due to optimistic growth forecasts for developing markets and higher commodity prices. U.S. CREDIT WOES RATTLED MARKETS Mounting problems in the U.S. subprime mortgage market led to concerns regarding global economic growth, generating periodic market volatility and contributing to a growing desire globally for less-risky assets. In an effort to soothe frayed nerves, the U.S. Federal Reserve (the Fed), the European Central Bank, and the Bank of England injected liquidity into their banking systems. A mid-September rate cut by the Fed served to strengthen the euro and British pound, relative to the sagging U.S. dollar. Late in the period, the dollar hit new record lows against those currencies. RATES ROSE IN EUROPE AND BRITAIN Healthy economic growth prompted the European Central Bank and the Bank of England to raise interest rates three times during the period. Although inflationary pressures remained at the fore, both banks held off making additional rate increases given the fallout from the credit-market turmoil. Optimism surrounding improving economic growth prompted the Bank of Japan to raise rates in February. Nevertheless, expectations for additional rate hikes went unfulfilled, as sluggish domestic consumption kept the central bank on hold. OPPORTUNITIES ABOUND Although the outlook for international equities remains somewhat uncertain, we believe international stocks present significant opportunities for investors. Combining the higher growth rate of the international markets with our international team's focus on companies with growth acceleration, we believe there is a significant opportunity to deliver attractive performance in the coming year.

The portfolio's benchmark, the MSCI EAFE Index, advanced 17.30%. Compared to its peers, International Growth outperformed the average return of 20.46%** for the 63 funds in Lipper Inc.'s International Large Cap Growth Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks. On an absolute basis, all sectors the portfolio invested in posted positive returns, and all but one sector (consumer discretionary) showed double-digit gains. Favorable stock selection in six of 10 sectors accounted for the portfolio's outperformance relative to the benchmark. From a country perspective, Japan (the portfolio's largest country weighting), India (which was not represented in the benchmark), and Germany made the greatest overall contributions to the portfolio's relative performance. Stock selection in Japan and Germany was effective, as were an underweight in Japan and an overweight in Germany. Despite its relatively small weighting, India had a strong impact on the portfolio's relative return. The worst country contributors to relative performance included the Netherlands, South Korea and Sweden. Our investments and an underweight hurt performance in the Netherlands, while our holdings in Sweden accounted for the lagging results. Our South Korean holdings posted a negative return for the reporting period, and the benchmark had no exposure to that market. FINANCIALS, INDUSTRIALS LED ALL SECTORS The financials sector, the largest weighting in the portfolio, made the greatest positive contribution to relative performance. In particular, our stock selections within the commercial banking and diversified financial services industries offered strong performance. Our overweight in Deutsche Boerse AG, the Germany-based owner of several securities exchanges, led to solid results. In addition, our position in China Merchants Bank, an emerging-market investment not represented in the benchmark, boosted performance, as the stock returned 142% during the reporting period. Top Ten Holdings as of November 30, 2007 % of net % of net assets as of assets as of 11/30/07 5/31/07 Deutsche Boerse AG 1.8% 1.2% Julius Baer Holding AG 1.8% 1.6% Nintendo Co., Ltd. 1.6% 1.6% Tesco plc 1.6% 1.6% National Bank of Greece SA 1.6% 1.6% BG Group plc 1.6% 1.3% Nestle SA 1.6% 1.1% Saipem SpA 1.6% 1.4% Novo Nordisk AS B Shares 1.5% -- Syngenta AG 1.5% 1.2% * All fund returns referenced in this commentary are for Investor Class shares. ** The Lipper Inc.'s International Large Cap Growth Funds category average returns for the five- and 10-year periods as of November 30, 2007, were 18.24% and 6.91%, respectively.

In particular, our stocks in the electrical equipment industry performed well, including Q-Cells AG, the German manufacturer of solar cells, and Vestas Wind Systems, a Danish supplier of wind power solutions. Our information technology stocks were also strong contributors, led by Japan's Nintendo, a videogame manufacturer, which advanced 160% during the reporting period on strong sales of its Wii gaming system. Nintendo was the portfolio's top-performing stock for the reporting period. CONSUMER SECTORS LAGGED Despite posting a total return of 22.70% for the reporting period, the portfolio's consumer staples sector was the greatest laggard relative to the benchmark. Our stock selection and underweight in the food products and tobacco industries primarily accounted for the shortfall. The consumer discretionary sector also detracted, primarily due to slumping stocks and an overweight, with stock selection in the automobile industry detracting the most in that sector. OUTLOOK International Growth seeks companies located throughout the world, excluding the United States, exhibiting accelerating earnings and revenue growth. Our analysis indicates the outlook for large-cap growth companies remains favorable. The portfolio has broad exposure to high-quality growth companies in numerous markets, and we believe these companies will deliver solid returns, even during volatile market conditions.

The portfolio's benchmark, the MSCI World Free Index, advanced 12.71%. The portfolio also outpaced the average return of 15.93%** for the 86 funds in Lipper Inc.'s Global Large Cap Growth Funds category. Strong worldwide economic growth and a series of U.S. Federal Reserve rate cuts helped generate strong 12-month performance among global stocks. Overall, stock selection was a strong positive contributor to portfolio performance, particularly in the United States, Germany and Japan, all of which outperformed the benchmark. Our holdings in the United States made the greatest contribution to return, followed by Germany and Japan. Sweden, Taiwan and Finland detracted most from the portfolio's relative performance. Lagging holdings were the overriding factor in Sweden and Finland. The benchmark had no exposure to Taiwan, while our small exposure to that country generated a negative return. On a positive note, the portfolio benefited from solid performance in the emerging markets of Mexico, India and Russia, which were not included in the benchmark. ALL SECTORS SHOWED POSITIVE RETURNS On an absolute basis, all sectors in the portfolio generated positive total returns, and all but one sector (utilities) recorded double-digit gains. Compared to the benchmark, all portfolio sectors outperformed except the utilities area. Our stock selection efforts were particularly strong in the financials, industrials and energy sectors. Deutsche Boerse AG, the Germany-based owner of several securities exchanges, was the portfolio's top performer in the financials sector. The company's plans to acquire U.S.-based International Securities Exchange Holdings and create a massive derivatives market helped drive performance. In addition, Julius Baer Holdings, the Swiss wealth-management company, which was not included in the benchmark, advanced on strong profit growth and a robust inflow of assets from its client base. Top Ten Holdings as of November 30, 2007 % of net % of net assets as of assets as of 11/30/07 5/31/07 Deutsche Boerse AG 2.5% 1.9% Saipem SpA 1.8% 1.6% National Bank of Greece SA 1.7% 1.7% Julius Baer Holding AG 1.7% 1.4% Allergan, Inc. 1.6% 1.4% Societe Generale 1.6% 0.9% Colgate-Palmolive Co. 1.6% 1.1% Shoppers Drug Mart Corp. 1.6% -- Cisco Systems Inc. 1.5% 2.0% Hewlett-Packard Co. 1.5% 1.9% * All fund returns referenced in this commentary are for Investor Class shares. ** The Lipper Inc.'s Global Large Cap Growth Funds category average returns for the five-year period as of November 30, 2007, was 15.96%.

In the electrical equipment area, our overweighted positions in Vestas Wind Systems, a Danish supplier of wind power solutions, and ABB Ltd., a Zurich-based provider of power and automation technologies to utilities and industries, drove performance. In the aerospace area, shares of Precision Castparts (which was not included in the benchmark), an Oregon-based manufacturer of casts for airline engines, soared on strong demand, surging sales and stellar profit growth. In the energy sector's equipment and services group, Italy's Saipem was a strong contributor. The company's stock, which was not included in the benchmark, benefited from its focus on deepwater exploration projects, an area gaining attention as worldwide oil reserves are shrinking. The portfolio's information technology sector also contributed positively to performance. This primarily was due to impressive results from Japanese videogame manufacturer Nintendo. The stock, which was among the top performers in the portfolio, advanced on strong worldwide sales of its Wii game console. UTILITIES POSTED LAGGING RESULTS Although our exposure to the utilities sector was minimal, it nevertheless detracted from relative performance. Our underweight combined with faltering stocks led to lagging results versus the benchmark. OUTLOOK Global Growth seeks to invest in companies located in developed countries throughout the world, including the United States, exhibiting accelerating growth characteristics. The portfolio has broad exposure to high-quality growth companies in numerous markets, and we believe these companies will deliver solid returns, even during volatile market conditions.

The portfolio's benchmark, the MSCI EM Index, advanced 45.57%. Compared to its peers, Emerging Markets outperformed the average return of 41.98%** for the 257 funds in Lipper Inc.'s Emerging Markets Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks, particularly those from the world's emerging markets. Emerging market stocks significantly outperformed the developed markets, which, as measured by the MSCI EAFE Index, returned 17.30% for the reporting period. The portfolio's performance benefited from this trend, and from our stock selection across most market sectors. Overall, stock selection accounted for the portfolio's outperformance relative to the benchmark. On an absolute basis, all sectors the portfolio invested in posted positive returns and made positive contributions to performance. Compared with the benchmark, each of the portfolio's market sectors outperformed except materials and financials. The portfolio also derived a portion of its returns from participating in several initial public offerings (IPOs). INDIA, RUSSIA, MEXICO OUTPERFORMED From a country perspective, India, Russia and Mexico had the greatest positive influence on the portfolio's relative performance. Stock selection was the key contributor in all three markets. Strong stock selection in South Korea also contributed to the portfolio's outperformance. Brazil and China detracted from the portfolio's relative performance, with stock selection accounting for the shortfall. TECH, ENERGY, CONSUMER DISCRETIONARY LED ALL SECTORS Good stock selection helped make the information technology sector the top contributor to the portfolio's relative performance. Our stock picks and allocation decisions were particularly strong in the semiconductor industry, where underweighting South Korea's Samsung Electronics, which faced waning demand in the memory chip market, proved effective.

Similarly, our favorable stock choices led to outperformance for the portfolio's consumer discretionary sector. For example, our out-of-benchmark position in Parkson Retail Group, which operates a chain of department stores in China, benefited from the company's expansion plans and China's growing retail market. In the auto components industry, Nokian Renkaat Oyj, another position not represented in the benchmark, contributed strongly to relative performance. The Finnish tire manufacturer advanced on strong sales and profit growth, primarily in Russia. MATERIALS, FINANCIALS LAGGED The materials and financials sectors were the largest detractors from the portfolio's relative performance. This primarily was due to our underweighted positions in both areas. Specifically, our underweight to the outperforming metals and mining industry hurt relative performance in the materials sector. The financials sector was the portfolio's largest, yet underweights and poor stock selection in the insurance and capital markets segments detracted from the portfolio's performance. The subprime mortgage market mess reverberated globally during the reporting period and dragged down holdings such as Shin Kong Financial Holding, a Taiwanese life insurer that acknowledged a portion of its fixed income portfolio was backed by U.S. subprime mortgages. In addition, not having any exposure to diversified financial services companies hurt the portfolio's results relative to the benchmark. OUTLOOK Focusing almost exclusively on equity securities of companies located in emerging market countries, we seek out companies with earnings and revenues growing at an improving rate. We will continue to select stocks based on extensive company-level research that focuses on identifying accelerating growth characteristics.

Its benchmark, the MSCI EAFE Index, returned 17.30%. The portfolio's performance reflected the generally positive global economic and investing climate prevailing during the fiscal year (see the Market Perspective on page 2). In that environment, every sector contributed to performance on an absolute basis. Relative to the benchmark, contribution to return was broad based, driven by holdings benefiting from global economic growth. In addition, good stock picks and an underweight position in financials shares helped performance. However, an underweight position among materials shares detracted from relative results. KEY CONTRIBUTORS The key theme explaining the portfolio's outperformance was its exposure to firms benefiting from economic expansion and a rise in living standards around the world. For example, the top contributor to return for the year was China Shenhua Energy. The company is the largest coal producer in China, which relies heavily on coal-fired plants to fuel its rapid expansion. Other top-10 contributors to performance were Shanghai Electric Group, which is China's biggest power-equipment maker, and Cheung Kong Holdings, a Hong Kong-listed stock with exposure to the strong Hong Kong and Chinese real estate markets. You can also see this theme at work in the portfolio's telecommunication services holdings, which benefited from exposure to growing emerging market economies. Key contributors in this space included BCE, Telefonos de Mexico, China Telecom, Telenor, and Telefonica. Spanish firm Telefonica is a good example -- it's an overweight position that gained more than 60% for the year on strong mobile subscriber growth in South America and continued to generate strong free cash flow. In addition, the company owns fixed and mobile providers in the Czech Republic, Argentina, and Great Britain. Similarly, the industrial sector was home to a number of leading contributors to portfolio performance, including Danish firm Vestas Wind Systems. The stock is a long-held overweight position and one of the largest stakes in the portfolio. It's a leading provider of wind turbines, and continued to benefit from demand for alternative energy sources driven by record-high oil prices.

Had the sales charge been applied, returns would have been lower than those shown. - ------ 26 International Value MATERIALS DETRACTED The portfolio's performance relative to the benchmark would have been even better but for positioning among materials shares, where an overweight position in the paper & forest products industry limited relative results. The business climate for these shares was difficult during the fiscal year because of falling demand for their products and rising costs associated with raw material prices. Leading detractors in this industry segment were Norwegian paper products firm Norske Skogindustrier and Finnish firm UPM-Kymmene, the world's leading producer of magazine paper. While these stocks underperformed, they are a good example of our value-oriented investment process at work. We're looking for companies trading at a discount to our estimate of their value, and our long-term approach means we're willing to build positions in out-of-favor industries where we believe the prospects for an eventual turnaround are good. That process led us to hold an overweight position in what we believe is a temporarily beaten-down industry that's attractively valued and that we believe is well on its way to restructuring and consolidation. STARTING POINT FOR NEXT REPORTING PERIOD "Because we build the International Value portfolio stock by stock, our sector and industry allocations typically reflect where we're finding the best values in the market at a given time," explained portfolio manager Guang Yang. "As of November 30, we continued to see opportunity in the telecommunication and industrials sectors, which were our largest overweight positions. At the same time, our most significant underweight position was in financial shares. In part this is because financials make up almost 30% of our index and we're reluctant to concentrate the portfolio so heavily in a single sector. But it's also because of earnings and valuation concerns we have for a number of companies in the sector amid difficult business conditions for many banks and other financial firms."

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 June 1, 2007 to November 30, 2007 (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. 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. - ------ 31 Expenses Paid Beginning Ending During Account Account Period(1) Annualized Value Value 6/1/07 - Expense 6/1/07 11/30/07 11/30/07 Ratio(1) International Growth ACTUAL Investor Class $1,000 $1,080.70 $6.68 1.28% Institutional Class $1,000 $1,082.00 $5.64 1.08% Advisor Class $1,000 $1,079.40 $7.98 1.53% A Class $1,000 $1,080.10 $7.98 1.53% B Class $1,000 $1,076.20 $11.87 2.28% C Class $1,000 $1,075.90 $11.87 2.28% R Class $1,000 $1,077.90 $9.27 1.78% HYPOTHETICAL Investor Class $1,000 $1,018.65 $6.48 1.28% Institutional Class $1,000 $1,019.65 $5.47 1.08% Advisor Class $1,000 $1,017.40 $7.74 1.53% A Class $1,000 $1,017.40 $7.74 1.53% B Class $1,000 $1,013.64 $11.51 2.28% C Class $1,000 $1,013.64 $11.51 2.28% R Class $1,000 $1,016.14 $9.00 1.78% Global Growth ACTUAL Investor Class $1,000 $1,078.20 $6.77 1.30% Institutional Class $1,000 $1,079.30 $5.73 1.10% A Class $1,000 $1,076.30 $8.07 1.55% B Class $1,000 $1,073.00 $11.95 2.30% C Class $1,000 $1,072.30 $11.95 2.30% R Class $1,000 $1,075.00 $9.36 1.80% HYPOTHETICAL Investor Class $1,000 $1,018.55 $6.58 1.30% Institutional Class $1,000 $1,019.55 $5.57 1.10% A Class $1,000 $1,017.30 $7.84 1.55% B Class $1,000 $1,013.54 $11.61 2.30% C Class $1,000 $1,013.54 $11.61 2.30% R Class $1,000 $1,016.04 $9.10 1.80% (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 183, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. - ------ 32 Expenses Paid Beginning Ending During Account Account Period(1) Annualized Value Value 6/1/07 - Expense 6/1/07 11/30/07 11/30/07 Ratio(1) Emerging Markets ACTUAL Investor Class $1,000 $1,222.50 $9.03 1.62% Institutional Class $1,000 $1,223.50 $7.92 1.42% A Class $1,000 $1,220.50 $10.41 1.87% B Class $1,000 $1,042.80(2) $4.62(3) 2.62% C Class $1,000 $1,216.10 $14.56 2.62% R Class $1,000 $1,043.60(2) $3.74(3) 2.12% HYPOTHETICAL Investor Class $1,000 $1,016.95 $8.19 1.62% Institutional Class $1,000 $1,017.95 $7.18 1.42% A Class $1,000 $1,015.69 $9.45 1.87% B Class $1,000 $1,011.93(4) $13.21(4) 2.62% C Class $1,000 $1,011.93 $13.21 2.62% R Class $1,000 $1,014.44(4) $10.71(4) 2.12% (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 183, 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. - ------ 40 NOTES TO FINANCIAL STATEMENTS NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century World Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. International Growth Fund (International Growth), Global Growth Fund (Global Growth), Emerging Markets Fund (Emerging Markets) and International Value Fund (International Value) (collectively, the funds) are four funds in a series issued by the corporation (see Note 9). The funds are diversified under the 1940 Act. International Growth, Global Growth and Emerging Markets' investment objective is to seek capital growth. International Value's investment objective is to seek long-term capital growth. International Growth pursues its objective by investing primarily in equity securities of foreign companies located in at least three developed countries (excluding the United States). Global Growth pursues its objective by investing primarily in equity securities of issuers in the United States and other developed countries. Emerging Markets invests at least 80% of its assets in securities of issuers in emerging market countries and companies that derive a significant portion of their business from emerging market countries. International Value pursues its objective by investing primarily in equity securities of foreign companies. International Value may also invest a portion of its assets in U.S. companies. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- International Growth 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. Global Growth is authorized to issue the Investor Class, the Institutional Class, the A Class (formerly Advisor Class) (see Note 10), the B Class, the C Class and the R Class. Emerging Markets is authorized to issue the Investor Class, the Institutional Class, the A Class (formerly Advisor Class), the B Class, the C Class and the R Class. International Value is 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 the funds 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 Global Growth's B Class commenced on December 1, 2005. Sale of Emerging Market's B Class and R Class commenced on September 28, 2007. Sale of International Value's 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. 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 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 as determined by, or in accordance with procedures adopted by, the Board of Directors or its designee if such determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to use alternative procedures to 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. - ------ 41 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) SECURITY TRANSACTIONS -- For financial reporting purposes, 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. Certain countries impose taxes on realized gains on the sale of securities registered in their country. The funds record the foreign tax expense, if any, on an accrual basis. The realized and unrealized tax provision reduces the net realized gain (loss) on investment transactions and net unrealized appreciation (depreciation) on investments, respectively. 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 -- International Growth, Global Growth and Emerging Markets may lend portfolio securities through their lending agent to certain approved borrowers in order to earn additional income. International Growth, Global Growth and Emerging Markets continue 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 foreign currency transactions and unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies, 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. REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) 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. The funds are no longer subject to examination by tax authorities for years prior to 2004. At this time, management has not identified any uncertain tax positions that would materially impact the financial statements. Accordingly, no provision has been made for federal or state income taxes. Interest and penalties associated with any federal or state income tax obligations, if any, are recorded as interest expense. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income, if any, are generally declared and paid annually. Distributions from net realized gains, if any, are generally declared and paid twice per year. The funds may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code, in all events in a manner consistent with provisions of the 1940 Act. - ------ 42 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) REDEMPTION -- The funds may impose a 2.00% redemption fee on shares held less than 60 days. The redemption fee may not be applicable to all classes. The redemption fee is recorded as a reduction in the cost of shares redeemed. The redemption fee is retained by the funds 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 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 On July 27, 2007, the Advisor Class shareholders of International Growth and the A Class (formerly Advisor Class, also referred to as "A Class (new)") shareholders of Global Growth and Emerging Markets approved a change to the class's fee structure. The change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. Effective September 4, 2007, the fee structure change resulted in an increase of 0.25% in the unified management fee and a simultaneous decrease of 0.25% in the total distribution and service fee, resulting in no change to the total operating expense ratio of the class. MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACGIM (the investment advisor), under which ACGIM 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 ACGIM. 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 strategy assets of International Growth includes the assets of NT International Growth Fund, one fund in a series issued by the corporation. The annual management fee schedule for International Growth ranges from 1.10% to 1.50% for the Investor Class, Advisor Class, A Class, B Class, C Class and R Class. Prior to September 4, 2007, the Advisor Class was 0.25% less at each point within the range for International Growth. The annual management fee schedule for Global Growth ranges from 1.05% to 1.30% for the Investor Class, A Class, B Class, C Class and R Class. The annual management fee schedule for Emerging Markets ranges from 1.25% to 1.85% for the Investor Class, A Class, B Class, C Class and R Class. Prior to September 4, 2007, the A Class (new) was 0.25% less at each point within the range for Global Growth and Emerging Markets. The annual management fee schedule for International Value ranges from 1.10% to 1.30% for the Investor Class, A Class, B Class, C Class and R Class. The Institutional Class of each fund is 0.20% less at each point within the range. - ------ 43 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) The effective annual management fee for each class of each fund for the year ended November 30, 2007, was as follows: Investor & C Institutional Advisor A B R International Growth 1.26% 1.06% 1.06% 1.26% 1.26% 1.26% Global Growth 1.30% 1.10% N/A 1.18% 1.30% 1.30% Emerging Markets 1.66% 1.46% N/A 1.50% 1.58% 1.58% International Value 1.30% 1.10% N/A 1.30% 1.30% 1.30% ACGIM has entered into a Subadvisory Agreement with ACIM (the subadvisor) on behalf of International Growth, Global Growth and Emerging Markets. The subadvisor makes investment decisions for the cash portion of International Growth, Global Growth and Emerging Markets in accordance with their investment objectives, policies and restrictions under the supervision of ACGIM and the Board of Directors. ACGIM pays all costs associated with retaining ACIM as the subadvisor of International Growth, Global Growth and Emerging Markets. ACGIM has entered into a Subadvisory Agreement with Templeton Investment Counsel, LLC (Templeton) on behalf of International Value. Templeton makes investment decisions for International Value in accordance with its investment objectives, policies, and restrictions under the supervision of ACGIM and the Board of Directors. ACGIM pays all costs associated with retaining Templeton as the subadvisor of International Value. DISTRIBUTION AND SERVICE FEES -- For International Growth, the Board of Directors has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the Advisor Class, A Class, B Class, C Class and R Class (collectively the International Growth plans), pursuant to Rule 12b-1 of the 1940 Act. The International Growth plans provide that the Advisor Class will pay American Century Investment Services, Inc. (ACIS) an annual distribution and service fee of 0.25%. Prior to September 4, 2007, the Board of Directors had adopted a Master Distribution and Shareholder Services Plan for the Advisor Class of International Growth, pursuant to Rule 12b-1 of the 1940 Act, which provided that the Advisor Class would pay ACIS an annual distribution fee of 0.25% and service fee of 0.25%.

SECURITIES LENDING As of November 30, 2007, securities in International Growth, Global Growth and Emerging Markets valued at $128,531, $28,070 and $57,610, respectively, 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 or ACGIM. 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 $132,398, $28,835 and $58,162, respectively. International Growth, Global Growth and Emerging Markets' 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 International Growth, Global Growth and Emerging Markets may be delayed or limited. 6. BANK LINE OF CREDIT International Growth, Global Growth and Emerging Markets, along with certain other funds managed by ACIM or ACGIM, have a $500 million unsecured bank line of credit agreement (the agreement) with JPMCB. International Value entered into the agreement on December 13, 2006. 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 0.40%. The funds did not borrow from the line during the year ended November 30, 2007. Effective December 12, 2007, the funds, along with certain other funds managed by ACIM or ACGIM, have a $500 million unsecured bank line of credit agreement with Bank of America, N.A. (the Bank of America agreement). The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the Bank of America agreement bear interest at the Federal Funds rate plus 0.40%. 7. RISK FACTORS There are certain risks involved in investing in foreign securities. These risks include those resulting from future adverse political, social, and economic developments, fluctuations in currency exchange rates, the possible imposition of exchange controls, and other foreign laws or restrictions. Investing in emerging markets may accentuate these risks. Emerging Market's performance may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund's performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund's performance as its assets grow. 8. FEDERAL TAX INFORMATION On December 18, 2007, International Growth, Emerging Markets and International Value declared and paid the following per-share distributions from net investment income to shareholders of record on December 17, 2007: Investor Institutional A B C R International Growth $0.0843 $0.1124 $0.0492 -- -- $0.0141 Emerging Markets $0.1027 $0.1265 $0.0729 -- -- $0.0432 International Value $0.2361 $0.2585 $0.2082 $0.1244 $0.1244 $0.1803 On December 18, 2007, International Growth, Global Growth and International Value declared and paid a per-share distribution from net realized gains to shareholders of record on December 17, 2007 of $0.7403, $1.9888 and $0.5580, respectively, for each class of the funds. On December 18, 2007, Emerging Markets declared and paid a per-share distribution from net realized gains to shareholders of record on December 17, 2007 of $1.0786 for the Investor Class, Institutional Class, A Class and R Class and $1.0623 for the B Class and C Class. - ------ 50 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) The tax character of distributions paid during the years ended November 30, 2007 and November 30, 2006 for International Growth, Global Growth and Emerging Markets were as follows: International Growth Global Growth Emerging Markets 2007 2006 2007 2006 2007 2006 DISTRIBUTIONS PAID FROM Ordinary income $19,973 $49,996 $1,986 $2,818 $64,774 $38,186 Long-term capital gain -- -- $9,099 -- $33,788 $22,096 The tax character of distributions paid during the year ended November 30, 2007, the eight months ended November 30, 2006 and the year ended March 31, 2006 for International Value were as follows: International Value Nov. 30, 2007 Nov. 30, 2006(1) March 31, 2006 DISTRIBUTIONS PAID FROM Ordinary income $3,184 -- $2,768 Long-term capital gain $18,548 -- $4,008 (1) April 1, 2006 through November 30, 2006, International Value's fiscal year end was changed from March 31 to November 30, resulting in an eight-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 November 30, 2007, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: International Global Emerging International Growth Growth Markets Value Federal tax cost of investments $2,065,967 $416,129 $904,079 $49,988 ============== ========= ========= ============== Gross tax appreciation of investments $719,073 $121,250 $349,266 $28,320 Gross tax depreciation of investments (14,202) (1,599) (12,648) (1,403) -------------- --------- --------- -------------- Net tax appreciation (depreciation) of investments $704,871 $119,651 $336,618 $26,917 ============== ========= ========= ============== Net tax appreciation (depreciation) on translation of assets and liabilities in foreign currencies $(1,196) $(38) $(3,588) $4 -------------- --------- --------- -------------- Net tax appreciation (depreciation) $703,675 $119,613 $333,030 $26,921 ============== ========= ========= ============== Undistributed ordinary income $18,363 $24,420 $63,284 $2,487 Accumulated long-term gains $139,372 $60,334 $70,118 $4,542 Currency loss deferrals $(104) $(6) $(75) $(12) 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, return of capital dividends and on investments in passive foreign investment companies. The currency loss deferrals listed above represent net foreign currency losses incurred in the one-month period ended November 30, 2007. The funds have elected to treat such losses as having been incurred in the following fiscal year for federal income tax purposes. - ------ 51 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 9. REORGANIZATION PLAN As of the close of business on March 31, 2006, International Value acquired all of the net assets of the Mason Street International Equity Fund (International Equity), one fund in a series issued by Mason Street Funds, Inc., pursuant to a plan of reorganization approved by the acquired fund's shareholders on March 15, 2006. International Value is maintaining the financial statements and performance history of International Equity. International Value's fiscal year end changed from March 31 to November 30. Prior to the reorganization, International Equity had A Class and B Class shares. At the close of business and as a result of the reorganization, A Class shares and B Class shares of the acquired fund were converted to A Class shares and B Class shares, respectively, of the surviving fund. A Class and B Class net assets of International Equity before the reorganization were $54,617 and $4,917, respectively. Immediately after the reorganization, A Class and B Class net assets of International Value were $54,617 and $4,917, respectively. 10. CORPORATE EVENT On July 27, 2007, the A Class (old) shareholders of Global Growth approved a reclassification of A Class (old) shares into Advisor Class shares. The change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. The reclassification was effective on September 4, 2007. Subsequent to the reclassification, the Advisor Class was renamed A Class. On September 25, 2007, the A Class shareholders of International Growth approved a reclassification of A Class shares into Advisor Class shares. The change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. The reclassification was effective December 3, 2007. Subsequent to the reclassification, the Advisor Class was renamed A Class. 11. 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. Management has concluded that the adoption of FIN 48 will not materially impact the financial statements. 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 that adopting FAS 157 will have on the financial statement disclosures. - ------ 52 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 12.

Total returns for periods less than one year are not annualized. The total return of the classes may not precisely reflect the class expense differences because of the impact of calculating the net asset values to two decimal places. If net asset values were calculated to three decimal places, the total return differences would more closely reflect the class expense differences.

See Notes to Financial Statements. - ------ 78 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders, American Century World Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of International Growth Fund, Global Growth Fund, Emerging Markets Fund, and International Value Fund (the "Funds"), four of the mutual funds comprising American Century World Mutual Funds, Inc., as of November 30, 2007, and the related statements of operations for the year then ended, and the statements of changes in net assets and the financial highlights for the periods presented (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 International Value Fund 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 November 30, 2007, 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 of American Century World Mutual Funds, Inc. as of November 30, 2007, the results of their operations for the year then ended, and the changes in their net assets and the financial highlights for the periods presented (except as noted above in reference to the report of other auditors), in conformity with accounting principles generally accepted in the United States of America.

Six classes of shares are authorized for sale by Global Growth, Emerging Markets and International Value: Investor Class, Institutional Class, A Class, B 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, A Class, B Class, C Class, and R Class shares are higher than that of Investor Class shares. The Advisor Class is no longer available effective December 3, 2007. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; and/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. The funds' prospectuses contain additional information regarding eligibility for Investor Class shares. 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. The unified management fee for Advisor Class shares is the same as for Investor Class shares. Advisor Class shares are subject to a 0.25% annual Rule 12b-1 distribution and service fee. 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. - ------ 85 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. - ------ 86 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.

[front cover] AMERICAN CENTURY INVESTMENTS Annual Report November 30, 2007 [photo of winter] International Stock Fund International Discovery Fund International Opportunities Fund [american century investments logo and text logo] OUR MESSAGE TO YOU [photo of Jonathan Thomas] JONATHAN THOMAS President and CEO American Century Companies, Inc. To help you monitor your investment, my colleagues and I take pride in providing you with the annual report for the American Century® International Stock, International Discovery and International Opportunities funds for the 12 months ended November 30, 2007. I am honored to be addressing you in the "Our Message" space long devoted to company founder Jim Stowers, Jr. and his son Jim Stowers III. Jim Stowers III stepped down from the American Century Companies, Inc. (ACC) board of directors in July 2007, his final step in a well-planned career transition to pursue new ventures outside the company. This reflected his family's support of our company's direction and its leadership team. The Stowers family remains an integral part of our heritage, leadership, and financial structure. In fact, Jim Stowers, Jr. continues as co-chair of the ACC board with Richard Brown, who has been on the board since 1998. American Century Investments, our clients, and our employees have been my top priority since I became company president and CEO in March, 2007. We have also added the executive talents of overall chief investment officer (CIO) Enrique Chang, international equity CIO Mark On, U.S. growth equity CIO Steve Lurito, and chief operating officer Barry Fink. This skilled group, combined with our existing senior management team, has already had a positive impact on the development and management of the products and services we take pride in delivering to you. We believe the ultimate measure of our performance is our clients' success. Therefore, our focus continues to be on building a long-term relationship with you and on delivering superior investment performance across our product line. /s/ Jonathan Thomas Jonathan Thomas [photo of James E.

MARKET PERSPECTIVE [photo of Chief Investment Officer] By Mark On, Chief Investment Officer, International Equity INTERNATIONAL STOCKS SHOWED ROBUST GAINS A strong global economy combined with relatively tame inflation and healthy labor markets helped promote stellar stock gains for the 12 months ended November 30, 2007. Among the developed markets, Europe fared well, with the strongest returns coming from the euro-zone nations. In contrast, performance was flat in Japan, as weak consumer spending, a challenging political climate, and slowing demand from the United States pressured Japan's stocks. Emerging markets remained the world's standout performers, due to optimistic growth forecasts for developing markets and higher commodity prices. U.S. CREDIT WOES RATTLED MARKETS Mounting problems in the U.S. subprime mortgage market led to concerns regarding global economic growth, generating periodic market volatility and contributing to a growing desire globally for less-risky assets. In an effort to soothe frayed nerves, the U.S. Federal Reserve (the Fed), the European Central Bank, and the Bank of England injected liquidity into their banking systems. A mid-September rate cut by the Fed served to strengthen the euro and British pound, relative to the sagging U.S. dollar. Late in the period, the dollar hit new record lows against those currencies. RATES ROSE IN EUROPE AND BRITAIN Healthy economic growth prompted the European Central Bank and the Bank of England to raise interest rates three times during the period. Although inflationary pressures remained at the fore, both banks held off making additional rate increases given the fallout from the credit-market turmoil. Optimism surrounding improving economic growth prompted the Bank of Japan to raise rates in February. Nevertheless, expectations for additional rate hikes went unfulfilled, as sluggish domestic consumption kept the central bank on hold. OPPORTUNITIES ABOUND Although the outlook for international equities remains somewhat uncertain, we believe international stocks present significant opportunities for investors. Combining the higher growth rate of the international markets with our international team's focus on companies with growth acceleration, we believe there is a significant opportunity to deliver attractive performance in the coming year.

The portfolio's benchmark, the MSCI EAFE Index, advanced 17.30%. Compared to its peers, International Stock outperformed the average return of 15.06%* for the 129 funds in Lipper Inc.'s International Multi-Cap Value Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks. On an absolute basis, all sectors the portfolio invested in posted positive, double-digit returns and made positive contributions to performance. Stock selection was the primary driver of the portfolio's overall outperformance relative to the benchmark. JAPAN, UK CONTRIBUTED STRONGLY From a country perspective, Japan, the United Kingdom and Germany made the greatest positive contributions to the portfolio's relative performance. Japan, the largest country weighting in the portfolio, benefited from strong stock selection and a significant underweight relative to the benchmark. Stock selection was the overriding positive influence in the United Kingdom and Germany. Maintaining an overweighted position in Germany also helped. Our small allocation to Sweden detracted from performance relative to the benchmark due to poor stock selection. Our small weighting to South Korea was another detractor, due to our unfavorable stock selections and the benchmark's avoidance of the market. FINANCIALS, INDUSTRIALS SHOWED STRONG RETURNS The financials sector, the largest weighting in the portfolio, was the top sector contributor, primarily due to strong stock selection. Specifically, our position in Deutsche Boerse AG, the Germany-based owner of several securities exchanges and one of the portfolio's largest holdings, made a strong showing. The company's plans to acquire U.S.-based International Securities Exchange Holdings to create a massive derivatives Top Ten Holdings as of November 30, 2007 % of % of net assets net assets as of as of 11/30/07 5/31/07 Deutsche Boerse AG 1.7% 1.1% Nintendo Co., Ltd. 1.7% 1.6% Julius Baer Holding AG 1.7% 1.3% National Bank of Greece SA 1.7% 1.6% Saipem SpA 1.6% 1.2% BG Group plc 1.5% 1.2% BHP Billiton Ltd. 1.5% 1.2% Tesco plc 1.4% 1.3% America Movil, SAB de CV ADR 1.4% 1.0% ABB Ltd. 1.4% 1.1% * Data provided by Lipper Inc. - A Reuters Company. ©2007 Reuters.

In addition, our position in China Merchants Bank, an emerging-market investment not represented in the benchmark, boosted performance, as the stock returned 142% during the reporting period. The portfolio's holdings in the industrials sector also contributed positively. Strong stock selection combined with an overweight to the sector drove outperformance. In particular, our stocks in the electrical equipment industry performed well, including Q-Cells AG, a German manufacturer of solar cells, and Vestas Wind Systems, a Danish supplier of wind power solutions. Our information technology stocks also were strong contributors, led by Japan's Nintendo, a videogame manufacturer, which advanced 160% during the reporting period on strong sales of its Wii gaming system. Nintendo was the portfolio's best-performing stock for the period. TELECOM, CONSUMER SECTORS LAGGED Despite a healthy absolute return of 28.47%, the portfolio's telecommunication services sector was the largest detractor on a relative basis. Our underweight to the sector accounted for the bulk of the underperformance. The portfolio's consumer staples sector returned 24.48% for the reporting period, but nevertheless weighed on relative performance as unfavorable stock selection led to lagging results compared to the benchmark. The consumer discretionary sector also detracted, due to our overweight and slumping stocks, with our stock selection in the automobile industry having the largest negative impact. OUTLOOK International Stock seeks companies located outside the United States exhibiting accelerating growth characteristics. Our analysis indicates the outlook for such companies remains favorable. The portfolio has broad exposure to high-quality growth companies in numerous markets, and we believe these companies will deliver solid returns, even during volatile markets.

The portfolio's benchmark, the S&P/Citigroup EMI Growth World ex-U.S. Index, advanced 14.82%. Compared to its peers, International Discovery outperformed the average return of 18.85%** for the 96 funds in Lipper Inc.'s International Small/Mid Cap Growth Funds category. Sustained global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks. The portfolio's holdings benefited from this trend. Overall, stock selection accounted for the portfolio's outperformance relative to the benchmark. On an absolute basis, all sectors in the portfolio posted positive returns and contributed to performance. The utilities sector, generally not viewed as a growth sector, was the only exception. Total returns in seven of the portfolio's 10 market sectors exceeded 33% for the reporting period, outperforming the benchmark handsomely. COUNTRY GAINS WERE WIDESPREAD From a country perspective, the portfolio enjoyed positive performance from most markets in which it invested. In particular, markets in Japan, Australia and China offered the greatest contributions on a relative basis. While benchmark returns for Japan were among the smallest, stock selection was a particularly strong factor among our holdings. Our overweights in Australia and China combined with good stock selection also contributed favorably. Taiwan (which was not represented in the benchmark), Greece and Singapore comprised the largest detractors to the portfolio's relative performance. On an absolute basis, performance in Taiwan was positive, but currency factors led to an overall negative effect on relative performance. The portfolio underperformed the benchmark in Greece, where stock selection was the culprit. In Singapore, our underweight accounted for the lagging results.

Continued strong financial results, positive product developments, and royalties received from the popular Gardasil vaccine for cervical cancer buoyed performance. CSL is the largest position in the portfolio. STOCK PICKS IN JAPAN BOOSTED SECTOR RESULTS Industrials, the portfolio's largest sector weighting, made the greatest contribution to relative performance, due to strong stock selection and an overweight to the sector. Our position in Japan Steel Works, a manufacturer of fabricating machinery, was particularly helpful, as the stock was among the portfolio's top 10 contributors for the reporting period. The company's stock participated in a rally among suppliers to the nuclear power industry, as officials in Texas announced plans to build two power-generating reactors. Similarly, stock selection in Japan contributed to our consumer discretionary sector's favorable performance. For example, the auto components industry was the sector's top contributor, primarily due to NGK Insulators, a Japanese manufacturer of various insulation products and one of the portfolio's best performers for the reporting period. The company's stock advanced on upgraded sales and profit projections. UTILITIES SECTOR LAGGED Our utilities sector, the smallest sector in the portfolio, was the only sector that detracted from relative performance. Stock selection primarily was to blame, as the few positions we owned performed poorly. Also, our underweight relative to the benchmark was a slightly negative influence. OUTLOOK We remain committed to our investment strategy of seeking the stocks of small- to mid-sized foreign companies we believe have a high likelihood of growing earnings and revenues at an improving rate. We select these stocks with the assistance of extensive company-level research that focuses on identifying accelerating growth characteristics.

The portfolio's benchmark, the S&P/Citigroup EMI Growth World ex-U.S. Index, advanced 14.82%. Compared to its peers, International Opportunities outperformed the average return of 18.85%** for the 96 funds in Lipper Inc.'s International Small/Mid Cap Growth Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks. On an absolute basis, all sectors the portfolio invested in posted positive, double-digit--and, in the case of energy, triple-digit--returns and contributed to absolute performance, except telecommunication services. Compared to the benchmark, eight out of 10 of the portfolio's market sectors outperformed, with the exception of utilities and telecommunication services. Overall, our stock selection was stellar, accounting for the bulk of the portfolio's outperformance. COUNTRY CONTRIBUTIONS WERE BROAD From a country perspective, most markets in which the portfolio invested contributed positively to total return. Markets in Japan, China, and Singapore were the strongest contributors to relative performance. Stock selection was positive in all three markets, and an underweight in Japan and overweights in China and Singapore contributed to the portfolio's outperformance versus the benchmark. Our exposure to Australia was the greatest detractor relative to the benchmark. A significant underweight combined with poor stock selection accounted for our underperformance. Our underweight in South Korea also contributed to lagging performance for that market. In addition, our exposure to Taiwan, which was not in the benchmark, detracted from relative performance.

For example, China's Li Ning, a fast-growing sports-apparel retailer not represented in the benchmark, was the sector's top contributor to performance. Growing consumer demand in China led to strong sales growth and soaring profits for the company. Favorable stock selection also led to strong performance for the portfolio's financials and energy sectors. China's Shenzhen Investment, a property developer not represented in the benchmark, was the financial sector's leading contributor. In energy, our overweighted position in Straits Asia Resources, a Singapore-based mining company, contributed strongly to performance on rising coal prices and robust demand. TELECOMM, UTILITIES SECTORS LAGGED Our stocks in the utilities sector, the portfolio's second-smallest sector weighting, represented the largest performance detractor in the portfolio. Our underweight combined with poor stock selection led to the lagging results. The portfolio's telecommunication services sector also detracted from relative performance. Stock selection was the major culprit, as the few positions we owned in this sector (the portfolio's smallest) performed poorly. Most of the benchmark companies in the telecommunication and utilities sectors have market capitalizations that exceed the portfolio's requirements. OUTLOOK We remain committed to our investment strategy of seeking the stocks of small, foreign companies we believe have a high likelihood of growing earnings and revenues at an improving rate. We select these stocks with the assistance of extensive company-level research that focuses on identifying accelerating growth characteristics.

See Notes to Financial Statements. - ------ 23 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 June 1, 2007 to November 30, 2007. 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. 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. - ------ 24 Expenses Paid Beginning Ending During Period* Annualized Account Account Value 6/1/07 - Expense Value 6/1/07 11/30/07 11/30/07 Ratio* International Stock ACTUAL Investor Class $1,000 $1,075.50 $7.80 1.50% HYPOTHETICAL Investor Class $1,000 $1,017.55 $7.59 1.50% International Discovery ACTUAL Investor Class $1,000 $1,080.40 $7.04 1.35% Institutional Class $1,000 $1,082.10 $6.00 1.15% Advisor Class $1,000 $1,079.40 $8.34 1.60% HYPOTHETICAL Investor Class $1,000 $1,018.30 $6.83 1.35% Institutional Class $1,000 $1,019.30 $5.82 1.15% Advisor Class $1,000 $1,017.05 $8.09 1.60% International Opportunities ACTUAL Investor Class $1,000 $1,042.20 $9.22 1.80% Institutional Class $1,000 $1,042.80 $8.19 1.60% HYPOTHETICAL Investor Class $1,000 $1,016.04 $9.10 1.80% Institutional Class $1,000 $1,017.05 $8.09 1.60% * 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 183, 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 World Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. International Stock Fund (International Stock), International Discovery Fund (International Discovery) and International Opportunities Fund (International Opportunities) (collectively, the funds) are three funds in a series issued by the corporation. The funds are diversified under the 1940 Act. The funds' investment objective is to seek capital growth. The funds pursue their objective by investing primarily in equity securities of foreign companies. International Stock primarily invests in securities of issuers in developed foreign countries that are large-sized companies. International Discovery primarily invests in securities of issuers in developed or emerging market countries that are small- to medium-sized companies at the time of purchase. International Opportunities primarily invests in securities of issuers in developed or emerging market countries that are small-sized companies at the time of purchase. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- International Stock is authorized to issue the Investor Class. International Discovery is authorized to issue the Investor Class, the Institutional Class and the Advisor Class. International Opportunities 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.

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. 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 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 as determined by, or in accordance with procedures adopted by, the Board of Directors or its designee if such determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to use alternative procedures to 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 -- For financial reporting purposes, 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. Certain countries impose taxes on realized gains on the sale of securities registered in their country. The funds record the foreign tax expense, if any, on an accrual basis. The realized and unrealized tax provision reduces the net realized gain (loss) on investment transactions and net unrealized appreciation (depreciation) on investments, respectively. 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 funds may lend portfolio securities through their lending agent to certain approved borrowers in order to earn additional income. The funds continue to recognize any gain or loss in the market price of the securities loaned and record any interest earned or dividends declared. - ------ 31 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 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 foreign currency transactions and unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies, 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) 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. The funds are no longer subject to examination by tax authorities for years prior to 2004. At this time, management has not identified any uncertain tax positions that would materially impact the financial statements. Accordingly, no provision has been made for federal or state income taxes. Interest and penalties associated with any federal or state income tax obligations, if any, are recorded as interest expense. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income, if any, are generally declared and paid annually. Distributions from net realized gains, if any, are generally declared and paid twice per year. The funds may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code, in all events in a manner consistent with provisions of the 1940 Act. REDEMPTION -- International Stock may impose a 2.00% redemption fee on shares held less then 60 days. International Discovery and International Opportunities may impose a 2.00% redemption fee on shares held less than 180 days. These fees may not be applicable to all classes. These redemption fees are recorded as a reduction in the cost of shares redeemed. These redemption fees are retained by the funds and help cover transaction costs that long-term investors may bear when a fund sells securities to meet investor redemptions. - ------ 32 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 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 On July 27, 2007, the Advisor Class shareholders of International Discovery approved a change to the class's fee structure. The change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. Effective September 4, 2007, the fee structure change resulted in an increase of 0.25% in the unified management fee and a simultaneous decrease of 0.25% in the total distribution and service fee, resulting in no change to the total operating expense ratio of the class. MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACGIM (the investment advisor), under which ACGIM 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 ACGIM. 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 International Stock ranges from 1.10% to 1.50% for the Investor Class. The annual management fee schedule for International Discovery ranges from 1.20% to 1.75% for the Investor Class and Advisor Class. The annual management fee schedule for International Opportunities ranges from 1.60% to 2.00% for the Investor Class. The Institutional Class is 0.20% less at each point within the range. Prior to September 4, 2007, the Advisor Class was 0.25% less at each point within the range for International Discovery. The effective annual management fee for each class of each fund for the year ended November 30, 2007, was as follows: Investor Institutional Advisor International Stock 1.50% N/A N/A International Discovery 1.35% 1.15% 1.29% International Opportunities 1.80% 1.60% N/A ACGIM has entered into a Subadvisory Agreement with ACIM (the subadvisor) on behalf of the funds. The subadvisor makes investment decisions for the cash portion of the funds in accordance with the funds' investment objectives, policies and restrictions under the supervision of ACGIM and the Board of Directors. ACGIM pays all costs associated with retaining ACIM as the subadvisor of the funds. - ------ 33 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) DISTRIBUTION AND SERVICE FEE -- The Board of Directors has adopted a Master Distribution and Individual 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 and service fee of 0.25%. Prior to September 4, 2007, the Board of Directors had adopted a Master Distribution and Shareholder Services Plan for the Advisor Class, pursuant to Rule 12b-1 of the 1940 Act, which provided that the Advisor Class would pay ACIS an annual distribution fee of 0.25% and service fee of 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 funds. The service fee provides compensation for shareholder and administrative services rendered by ACIS, its affiliates or independent third party providers. Fees incurred under the plans during the year ended November 30, 2007, 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, ACGIM, the corporation's subadvisor, ACIM, the distributor of the corporation, ACIS, and the corporation's transfer agent, American Century Services, LLC. Beginning in December 2006, the funds are eligible to invest in a money market fund for temporary purposes, which is managed by J.P. Morgan Investment Management, Inc. (JPMIM). JPMIM is a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. The funds have a bank line of credit agreement and securities lending agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the funds and a wholly owned subsidiary of JPM. 3.

SECURITIES LENDING As of November 30, 2007, securities in International Stock, International Discovery and International Opportunities valued at $7,257, $50,160 and $30,481, respectively, 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 or ACGIM. 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 $7,501, $49,850 and $31,901, respectively. The funds' 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 funds 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 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 0.40%. The funds did not borrow from the line during the year ended November 30, 2007. Effective December 12, 2007, the funds, along with certain other funds managed by ACIM or ACGIM, have a $500 million unsecured bank line of credit agreement with Bank of America, N.A. (the Bank of America agreement). The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the Bank of America agreement bear interest at the Federal Funds rate plus 0.40%. 7. RISK FACTORS There are certain risks involved in investing in foreign securities. These risks include those resulting from future adverse political, social, and economic developments, fluctuations in currency exchange rates, the possible imposition of exchange controls, and other foreign laws or restrictions. Investing in emerging markets may accentuate these risks. 8. FEDERAL TAX INFORMATION On December 18, 2007, the funds declared and paid the following per-share distributions from net investment income to shareholders of record on December 17, 2007: Investor Institutional Advisor International Stock $0.1233 N/A N/A International Discovery $0.0514 $0.0858 $0.0084 International Opportunities $0.0491 $0.0700 N/A On December 18, 2007, International Stock, International Discovery and International Opportunities declared and paid a per-share distribution from net realized gains to shareholders of record on December 17, 2007 of $0.6521, $3.7176 and $2.4668, respectively, for each class of the funds. - ------ 36 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) The tax character of distributions paid during the years ended November 30, 2007 and November 30, 2006 were as follows: International Stock International Discovery 2007 2006 2007 2006 DISTRIBUTIONS PAID FROM Ordinary income $320 $155 $117,025 $115,168 Long-term capital gains -- -- $256,891 $132,385 International Opportunities 2007 2006 DISTRIBUTIONS PAID FROM Ordinary income $9,422 $19,416 Long-term capital gains $43,224 $29,526 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 November 30, 2007, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: International International International Stock Discovery Opportunities Federal tax cost of investments $122,751 $1,554,564 $199,770 ============ ============= ============= Gross tax appreciation of investments $30,592 $447,852 $53,859 Gross tax depreciation of investments (1,090) (36,098) (6,054) ------------ ------------- ------------- Net tax appreciation (depreciation) of investments $29,502 $411,754 $47,805 ============ ============= ============= Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies $(7) $(285) $(59) ------------ ------------- ------------- Net tax appreciation (depreciation) $29,495 $411,469 $47,746 ============ ============= ============= Undistributed ordinary income $3,003 $142,707 $18,331 Accumulated long-term gains $3,692 $293,720 $31,732 Capital loss deferrals $(233) -- -- Currency loss deferrals -- $(378) -- 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 on investments in passive foreign investment companies. The capital and currency loss deferrals listed above represent net capital and foreign currency losses incurred in the one-month period ended November 30, 2007. The funds have elected to treat such losses as having been incurred in the following fiscal year for federal income tax purposes. - ------ 37 NOVEMBER 30, 2007 (AMOUNTS IN THOUSANDS) 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. Management has concluded that the adoption of FIN 48 will not materially impact the financial statements. 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 that adopting FAS 157 will have on the financial statement disclosures. 10.

See Notes to Financial Statements. - ------ 44 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders, American Century World Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of International Stock Fund, International Discovery Fund and International Opportunities Fund (the "Funds"), three of the mutual funds comprising American Century World Mutual Funds, Inc., as of November 30, 2007, and the related statements 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 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 November 30, 2007, 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 of American Century World Mutual Funds, Inc. as of November 30, 2007, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and the financial highlights for each of the periods presented, in conformity with accounting principles generally accepted in the United States of America.

Three classes of shares are authorized for sale by International Discovery: Investor Class, Institutional Class and Advisor Class. Two classes of shares are authorized for sale by International Opportunities: Investor Class and Institutional 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; and/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. The funds' prospectuses contain additional information regarding eligibility for Investor Class shares. 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. The unified management fee for Advisor Class shares is the same as for Investor Class shares. Advisor Class shares are subject to a 0.25% 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. - ------ 51 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.

[front cover] AMERICAN CENTURY INVESTMENTS Annual Report November 30, 2007 [winter photo] Life Sciences Fund Technology Fund [american century investments logo and text logo] OUR MESSAGE TO YOU [photo of Jonathan Thomas] JONATHAN THOMAS President and CEO American Century Companies, Inc. To help you monitor your investment, my colleagues and I take pride in providing you with the annual report for the American Century® Life Sciences and Technology funds for the 12 months ended November 30, 2007. I am honored to be addressing you in the "Our Message" space long devoted to company founder Jim Stowers, Jr. and his son Jim Stowers III. Jim Stowers III stepped down from the ACC board in July 2007, his final step in a well-planned career transition to pursue new ventures outside the company. This reflected his family's support of our company's direction and the leadership team of American Century Investments. The Stowers family remains an integral part of our heritage, leadership, and financial structure. In fact, Jim Stowers, Jr. continues as co-chair of the American Century Companies, Inc. (ACC) board of directors with Richard Brown, who has been on the board since 1998. American Century Investments, our clients, and our employees have been my top priority since I became company president and CEO in March, 2007. We have also added the executive talents of overall chief investment officer (CIO) Enrique Chang, international equity CIO Mark On, U.S. growth equity CIO Steve Lurito, and chief operating officer Barry Fink. This skilled group, combined with our existing senior management team, has already had a positive impact on the development and management of the products and services we take pride in delivering to you. We believe the ultimate measure of our performance is our clients' success. Therefore, our focus continues to be on building a long-term relationship with you and on delivering superior investment performance across our product line. /s/Jonathan Thomas [photo of James E.

MARKET PERSPECTIVE [photo of Chief Investment Officer] By Enrique Chang, Chief Investment Officer, American Century Investments STOCKS ADVANCED DESPITE INCREASE IN VOLATILITY The broad U.S. stock indexes gained ground for the 12 months ended November 30, 2007, despite facing a confluence of challenges that led to extraordinary market volatility. The stock market generally rallied during the first half of the period, with the exception of a brief drop in late February caused by a drop in the Chinese stock market and growing financial troubles among subprime mortgage lenders. Stocks benefited from corporate earnings growth, which gradually decelerated but continued to surpass expectations, and robust merger activity, which continued at a brisk pace thanks to leveraged buy-outs from private equity firms. After reaching all-time highs in mid-July, however, the major stock indexes declined sharply as subprime lending problems worsened, leading to a credit crisis that threatened to derail the economic expansion. Tighter lending standards crimped funding for leveraged buy-outs, removing an important leg of support for the stock market, and rising energy and commodity prices sparked inflation worries despite slowing economic activity. As investors grew increasingly risk-averse, the Federal Reserve (the Fed) lowered its discount rate in mid-August and its federal funds rate target in both September and October -- the Fed's first rate cuts since June 2003. The Fed's actions helped alleviate some of the credit and economic concerns, allowing the major stock indexes to stage an uneven recovery in September and October. However, stocks finished the period on a down note, declining in November amid reports of further subprime-related losses. Energy was the best-performing sector in the stock market during the 12-month period, benefiting from a 40% increase in the price of oil. Materials and utilities stocks also fared well. The only two sectors of the market to decline during the period were financials and consumer discretionary. ECONOMIC STRENGTH BOOSTED FOREIGN STOCKS Overseas stock markets comfortably outperformed domestic equities during the period, benefiting from strong economic conditions outside the U.S. Weakness in the U.S. dollar also contributed favorably to international stock returns. By far, emerging markets generated the best results, while Pacific Rim countries (excluding Japan, which posted modest gains) were the top performers among developed markets.

The portfolio's benchmark, the S&P Composite 1500 Health Care Index, returned 11.93%. The broader equity market, represented by the S&P 500 Index, returned 7.72%. The portfolio outperformed the average return for the 180 funds in the Lipper Health/Biotechnology Funds category, which returned 11.73%.** Periods of volatility in the equity markets generally led to better performance from companies with stable earnings-growth prospects. This sentiment helped the health care sector and led to gains in the portfolio and its benchmark. We also allocated a portion of Life Science's assets to holdings of companies outside of the United States. The portfolio benefited from this allocation, as international stocks generated higher returns than the domestic market, boosted by improving global economic conditions and a declining U.S. dollar. STOCK SELECTION DROVE RESULTS Strong stock selection throughout the health care industry accounted for the majority of the portfolio's outperformance relative to the benchmark. Additionally, overweights in health care equipment and life sciences tools and services and an underweight in the struggling pharmaceuticals area contributed positively to the portfolio's performance. In the health care equipment category, our overweight position in Respironics, a manufacturer of respiratory products that treat sleep disorders, boosted performance. The company, which reported record earnings and revenue growth in the third calendar quarter of 2007, was among the portfolio's top-10 contributors for the reporting period. Our position in Waters Corp. was the top contributor in the life sciences tools and services segment and one of the portfolio's top 10 contributing securities. The company, which produces analytical instruments for research labs, experienced strong stock gains due to earnings growth and a favorable spending environment. Another top contributor was Thermo Fisher Scientific, which has prospered since the merger of Thermo Electron and Fisher Scientific International created the company in late 2006. The supplier of laboratory devices reported solid revenues and profits and increased its full-year earnings and revenue projections for 2007. Top Ten Holdings as of November 30, 2007 % of % of net assets net assets as of as of 11/30/07 5/31/07 Merck & Co., Inc 5.8% 4.9% Thermo Fisher Scientific Inc. 5.6% 5.1% Johnson & Johnson 5.1% 2.6% Abbott Laboratories 4.3% 3.5% Manor Care, Inc. 4.1% 3.6% Gilead Sciences, Inc 3.7% 2.6% Baxter International Inc. 3.6% 3.2% Respironics, Inc. 3.0% 2.8% Schering-Plough Corp. 2.9% 1.5% Novartis AG ADR 2.8% 2.5% * All fund returns referenced in this commentary are for Investor Class shares. ** As of November 30, 2007, the five-year average return for the 144 funds in the Lipper category was 11.93%. - ------ 5 Life Sciences UNDERWEIGHTS HELPED IN PHARMACEUTICALS Although pharmaceuticals represented the largest weighting in the portfolio, our hefty underweight compared to the benchmark was a positive influence on relative performance. Our underweighted positions in some drug makers (such as Johnson & Johnson), and avoidance of others (including Pfizer and Eli Lilly), paid off during the reporting period. Many drug companies posted significant losses -- some due to regulatory issues and others due to disappointing financial results -- and our strategy helped the portfolio's relative performance. OUT-OF-BENCHMARK POSITIONS HELPED A small, out-of-benchmark weighting to the materials industry contributed favorably to the portfolio's relative performance. Specifically, in the materials sector, our exposure to the chemicals industry through a position in Sigma-Aldrich Corp. was a positive influence. INDIVIDUAL NAMES DETRACTED All sectors in which the portfolio invested contributed positively to relative performance. In general, detractors included stocks that performed well but were either not represented or were underweighted in the portfolio. For example, Medco Health Solutions, the pharmacy benefit manager, represented the largest individual detractor to the portfolio's relative performance. This outperforming stock was included in the benchmark but not in the portfolio. STARTING POINT FOR NEXT REPORTING PERIOD Regardless of the macro-economic environment, we will continue to emphasize companies exhibiting accelerating earnings in our attempt to build and maintain a portfolio of strong individual companies. Our investment decisions may result in shifts in industry weightings, but any such developments stem from a fundamental, bottom-up assessment of each company's merits.

The portfolio's benchmark, the S&P Composite 1500 Technology Index, returned 12.50%. The broader equity market, represented by the S&P 500 Index, returned 7.72%. The portfolio outperformed the average return of 13.66%** for the 270 funds in the Lipper Science and Technology Funds category. With mounting concerns surrounding U.S. economic growth prospects, investors returned to the traditional growth sectors during the reporting period. This sentiment helped the technology sector, where firms with accelerating earnings and revenue growth rates and positive share price momentum performed well. In addition, more than 23% of the portfolio's assets were allocated to foreign stocks during the period (down slightly from 28% on May 31, 2007). The portfolio benefited significantly from this allocation as international stocks generated higher returns than the domestic market, boosted by improving global economic conditions and a declining U.S. dollar. STOCK SELECTION DROVE RESULTS Strong stock selection accounted for the bulk of our portfolio's outperformance relative to the benchmark. Additionally, our holdings in the industrials and telecommunication services sectors made positive contributions. RIM WAS TOP CONTRIBUTOR The portfolio's communication equipment segment made the greatest contribution to returns, primarily due to strong performance from Research in Motion (RIM), the Canadian manufacturer of the BlackBerry wireless handheld device. RIM was the portfolio's top absolute and relative contributor and largest holding. The company benefited from multiple new product cycles, expanding market share, and increasing demand for smartphones, which led to accelerating revenue and earnings growth rates throughout the year. RIM continues to enjoy strong subscriber growth, and the company's earnings and revenue outlooks are robust. As such, the company remains among our portfolio's largest holdings. In the software industry, the portfolio's performance benefited from investments in Vasco Data Security and Nintendo, but was hindered by i2 Technologies. Vasco Data Security, the provider of security software, is benefiting from the growth in online banking and from the increasing need for strong user authentication for online access Top Ten Holdings as of November 30, 2007 % of % of net assets net assets as of as of 11/30/07 5/31/07 Research In Motion Ltd. 8.0% 4.6% Google Inc.

Nintendo, a Japanese videogame manufacturer, is experiencing strong growth from its new Wii and next generation Nintendo DS game consoles. Hurt by disappointing software sales and the departure of its CEO, i2 Technologies was the portfolio's biggest software detractor. INDUSTRIALS, TELECOM ENHANCE RESULTS In the industrials sector, our investment in aerospace-and-defense-industry component Precision Castparts, the Oregon-based manufacturer of casts for airline engines, soared on strong demand, surging sales and stellar profit growth. Precision Castparts was among the portfolio's top contributors. Our positive performance in the telecommunication services sector reflected the growing demand for such services in the emerging markets. For example, our position in Millicom International Cellular, the Luxembourg-based provider of prepaid cellular phone service in developing countries, contributed strongly and was among the portfolio's leading contributors. In the internet group, our second largest holding, Google, continued to gain market share in internet search and internet advertising. The stock was up 42.94% for the year. Ebay, an e-commerce marketplace, failed to meet rising investor expectations and was among the portfolio's biggest absolute and relative detractors. In the semiconductor industry, MEMC Electronic Materials, a maker of silicon wafers and polysilicon, benefited from rising demand for semiconductors and rapidly increasing demand for silicon-based solar cells. Our position in Credence Systems, a manufacturer of test and analytical equipment for the global semiconductor industry, hindered performance, as the company experienced poor execution and sales shortfalls at key customer Advanced Micro Devices. STARTING POINT FOR NEXT REPORTING PERIOD We will continue to focus on technology firms with accelerating earnings and revenue growth rates and positive share price momentum, as we believe such stocks will generate superior returns over time. Although returns from technology stocks have been strong recently, it's important to remember sector funds can show strong volatility to the up and down sides. Therefore, it may be best to use such funds in the context of a larger, long-term, growth-oriented strategy.

See Notes to Financial Statements. - ------ 14 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 June 1, 2007 to November 30, 2007. 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. 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. - ------ 15 Expenses Paid Beginning Ending During Period* Annualized Account Account Value 6/1/07 -- Expense Value 6/1/07 11/30/07 11/30/07 Ratio* Life Sciences ACTUAL Investor Class $1,000 $1,030.90 $6.87 1.35% Institutional $1,000 $1,030.50 $5.85 1.15% Class Advisor Class $1,000 $1,029.70 $8.14 1.60% C Class $1,000 $1,025.40 $11.93 2.35% HYPOTHETICAL Investor Class $1,000 $1,018.30 $6.83 1.35% Institutional $1,000 $1,019.30 $5.82 1.15% Class Advisor Class $1,000 $1,017.05 $8.09 1.60% C Class $1,000 $1,013.29 $11.86 2.35% Technology ACTUAL Investor Class $1,000 $1,077.40 $7.81 1.50% Institutional $1,000 $1,078.40 $6.77 1.30% Class Advisor Class $1,000 $1,075.90 $9.11 1.75% HYPOTHETICAL Investor Class $1,000 $1,017.55 $7.59 1.50% Institutional $1,000 $1,018.55 $6.58 1.30% Class Advisor Class $1,000 $1,016.29 $8.85 1.75% *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 183, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. -

------ 19 NOTES TO FINANCIAL STATEMENTS NOVEMBER 30, 2007 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century World Mutual Funds, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act) as an open-end management investment company. Life Sciences Fund (Life Sciences) and Technology Fund (Technology) (collectively, the funds) are two funds in a series issued by the corporation. The funds are non-diversified under the 1940 Act. The funds' investment objectives are to seek capital growth. Life Sciences and Technology pursue their objectives by seeking to invest primarily in stocks of growing companies in the life sciences and in the technology and telecommunications-related sectors, respectively. Specifically, Life Sciences invests at least 80% of its assets in companies that engage in the business of providing products and services that help promote health and wellness. In addition, Technology invests at least 80% of its assets in companies primarily engaged in offering, using or developing products, processes or services that provide or will benefit significantly from technological advancements or improvements. The following is a summary of the funds' significant accounting policies. MULTIPLE CLASS -- Life Sciences is authorized to issue the Investor Class, the Institutional Class, the Advisor Class and the C Class. Technology is authorized to issue the Investor Class, the Institutional Class and the Advisor 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. 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 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 as determined by, or in accordance with procedures adopted by, the Board of Directors or its designee if such determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to use alternative procedures to 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 -- For financial reporting purposes, 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. Certain countries impose taxes on realized gains on the sale of securities registered in their country. The funds record the foreign tax expense, if any, on an accrual basis. The realized and unrealized tax provision reduces the net realized gain (loss) on investment transactions and net unrealized appreciation (depreciation) on investments, respectively. 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. - ------ 20 EXCHANGE TRADED FUNDS -- The funds may invest in exchange traded funds (ETFs). ETFs are a type of index fund bought and sold on a securities exchange. An ETF trades like common stock and represents a fixed portfolio of securities designed to track the performance and dividend yield of a particular domestic or foreign market index. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although the lack of liquidity on an ETF could result in it being more volatile. Additionally, ETFs have management fees, which increase their cost. 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) 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. The funds are no longer subject to examination by tax authorities for years prior to 2004. At this time, management has not identified any uncertain tax positions that would materially impact the financial statements. Accordingly, no provision has been made for federal or state income taxes. Interest and penalties associated with any federal or state income tax obligations, if any, are recorded as interest expense. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income, if any, are generally declared and paid annually. Distributions from net realized gains, if any, are generally declared and paid twice per year. The funds may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code, in all events in a manner consistent with provisions of the 1940 Act. - ------ 21 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 On July 27, 2007, the Advisor Class shareholders of Life Sciences and Technology approved a change to the class's fee structure. The change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. Effective September 4, 2007, the fee structure change resulted in an increase of 0.25% in the unified management fee and a simultaneous decrease of 0.25% in the total distribution and service fee, resulting in no change to the total operating expense ratio of the class. MANAGEMENT FEES -- The corporation has entered into a Management Agreement with ACIM for Technology and ACGIM for Life Sciences (the investment advisor, respectively), under which the investment advisor 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 the investment advisor. 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.

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 0.40%. The funds did not borrow from the line during the year ended November 30, 2007. Effective December 12, 2007, the funds, along with certain other funds managed by ACIM or ACGIM, have a $500,000,000 unsecured bank line of credit agreement with Bank of America, N.A (the Bank of America agreement). The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the Bank of America agreement bear interest at the Federal Funds rate plus 0.40%. - ------ 24 6. RISK FACTORS The funds concentrate their investments in a narrow segment of the total market. Because of this, the funds may be subject to greater risks and market fluctuations than a portfolio representing a broader range of industries. In addition, its investment approach may involve higher volatility and risk. There are certain risks involved in investing in foreign securities. These risks include those resulting from future adverse political, social, and economic developments, fluctuations in currency exchange rates, the possible imposition of exchange controls, and other foreign laws or restrictions. Technology's investment process may result in high portfolio turnover, high commission costs and high capital gains distributions. Investing in emerging markets may accentuate these risks. 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 funds during the years ended November 30, 2007 and November 30, 2006. As of November 30, 2007, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: Life Sciences Technology Federal tax cost of investments $83,626,472 $118,867,589 ============ ============== Gross tax appreciation of investments $20,020,968 $21,134,281 Gross tax depreciation of investments (919,343) (2,947,024) ------------ -------------- Net tax appreciation (depreciation) of investments $19,101,625 $18,187,257 ============ ============== Net tax appreciation (depreciation) on derivatives and translation of assets and liabilities in foreign currencies $912 $1,084 ------------ -------------- Net tax appreciation (depreciation) $19,102,537 $18,188,341 ============ ============== Accumulated capital losses $(9,361,643) $(195,624,136) Capital loss deferrals $(134,074) -- Currency loss deferrals $(18,958) -- 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 Life Sciences -- $(9,361,643) Technology $(142,889,307) $(52,734,829) The capital and currency deferrals represent net capital and foreign currency losses incurred in the one-month period ended November 30, 2007. The funds have elected to treat such losses as having been incurred in the following fiscal year for federal income tax purposes. 8. CORPORATE EVENT On July 27, 2007, the Advisor Class and C Class shareholders of Life Sciences approved a reclassification of Advisor Class and C Class shares into Investor Class shares. On July 27, 2007, the Advisor Class shareholders of Technology approved a reclassification of Advisor Class shares into Investor Class shares. Each change was approved by the Board of Directors on November 29, 2006 and March 7, 2007. The reclassification was effective December 3, 2007. - ------ 25 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. Management has concluded that the adoption of FIN 48 will not materially impact the financial statements. 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 that adopting FAS 157 will have on the financial statement disclosures. - ------ 26 FINANCIAL HIGHLIGHTS Life Sciences Investor Class For a Share Outstanding Throughout the Years Ended November 30 2007 2006 2005 2004 2003 PER-SHARE DATA Net Asset Value, Beginning of Period $5.22 $5.32 $4.69 $4.36 $3.54 -------- -------- -------- -------- -------- Income From Investment Operations Net Investment Income (Loss)(1) (0.02) (0.04) (0.04) (0.04) (0.03) Net Realized and Unrealized Gain (Loss) 0.80 (0.06) 0.67 0.37 0.85 -------- -------- -------- -------- -------- Total From Investment Operations 0.78 (0.10) 0.63 0.33 0.82 -------- -------- -------- -------- -------- Net Asset Value, End of Period $6.00 $5.22 $5.32 $4.69 $4.36 ======== ======== ======== ======== ======== TOTAL RETURN(2) 14.94% (1.88)% 13.43% 7.57% 23.16% RATIOS/SUPPLEMENTAL DATA Ratio of Operating Expenses to Average Net Assets 1.35% 1.46% 1.50% 1.50% 1.50% Ratio of Net Investment Income (Loss) to Average Net Assets (0.39)% (0.67)% (0.81)% (0.85)% (0.89)% Portfolio Turnover Rate 73% 151% 162% 215% 138% Net Assets, End of Period (in thousands) $100,120 $112,648 $155,835 $155,530 $160,187 (1) Computed using average shares outstanding throughout the period.

See Notes to Financial Statements. - ------ 33 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders, American Century World Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of Life Sciences Fund and Technology Fund (the "Funds"), two of the mutual funds comprising American Century World Mutual Funds, Inc., as of November 30, 2007, and the related statements 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 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.

Three classes of shares are authorized for sale by Technology: 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 ratios of Advisor Class and C Class shares are higher than that of Investor Class shares. The Advisor Class and C Class are no longer available effective December 3, 2007. INVESTOR CLASS shares are available for purchase in two ways: 1) directly from American Century without any commissions or other fees; and/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. The funds' prospectuses additional information regarding eligibility for Investor Class shares. 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. The unified management fee for Advisor Class shares is the same as for Investor Class shares. Advisor Class shares are subject to a 0.25% annual Rule 12b-1 distribution and service fee. 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%. All classes of shares represent a pro rata interest in the funds 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.

[front cover] AMERICAN CENTURY INVESTMENTS Annual Report November 30, 2007 [photo of winter] NT International Growth Fund NT Emerging Markets Fund [american century investments logo and text logo] OUR MESSAGE TO YOU To help you monitor your investment, my colleagues and I take pride in providing you with the annual report for the American Century® NT International Growth and NT Emerging Markets funds for the 12 months ended November 30, 2007. I am honored to be addressing you in the "Our Message" space long devoted to company founder Jim Stowers, Jr. and his son Jim Stowers III. Jim Stowers III stepped down from the American Century Companies, Inc. (ACC) board of directors in July 2007, his final step in a well-planned career transition to pursue new ventures outside the company. This reflected his family's support of our company's direction and its leadership team. The Stowers family remains an integral part of our heritage, leadership, and financial structure. In fact, Jim Stowers, Jr. continues as co-chair of the ACC board with Richard Brown, who has been on the board since 1998. American Century Investments, our clients, and our employees have been my top priority since I became company president and CEO in March, 2007. We have also added the executive talents of overall chief investment officer (CIO) Enrique Chang, international equity CIO Mark On, U.S. growth equity CIO Steve Lurito, and chief operating officer Barry Fink. This skilled group, combined with our existing senior management team, has already had a positive impact on the development and management of the products and services we take pride in delivering to you. We believe the ultimate measure of our performance is our clients' success. Therefore, our focus continues to be on building a long-term relationship with you and on delivering superior investment performance across our product line. /s/Jonathan Thomas Jonathan Thomas [photo of Jonathan Thomas] JONATHAN THOMAS President and CEO American Century Companies, Inc.

MARKET PERSPECTIVE [photo of Chief Investment Officer] By Mark On, Chief Investment Officer, International Equity INTERNATIONAL STOCKS SHOWED ROBUST GAINS A strong global economy combined with relatively tame inflation and healthy labor markets helped promote stellar stock gains for the 12 months ended November 30, 2007. Among the developed markets, Europe fared well, with the strongest returns coming from the euro-zone nations. In contrast, performance was flat in Japan, as weak consumer spending, a challenging political climate, and slowing demand from the United States pressured Japan's stocks. Emerging markets remained the world's standout performers, due to optimistic growth forecasts for developing markets and higher commodity prices. U.S. CREDIT WOES RATTLED MARKETS Mounting problems in the U.S. subprime mortgage market led to concerns regarding global economic growth, generating periodic market volatility and contributing to a growing desire globally for less-risky assets. In an effort to soothe frayed nerves, the U.S. Federal Reserve (the Fed), the European Central Bank, and the Bank of England injected liquidity into their banking systems. A mid-September rate cut by the Fed served to strengthen the euro and British pound, relative to the sagging U.S. dollar. Late in the period, the dollar hit new record lows against those currencies. RATES ROSE IN EUROPE AND BRITAIN Healthy economic growth prompted the European Central Bank and the Bank of England to raise interest rates three times during the period. Although inflationary pressures remained at the fore, both banks held off making additional rate increases given the fallout from the credit-market turmoil. Optimism surrounding improving economic growth prompted the Bank of Japan to raise rates in February. Nevertheless, expectations for additional rate hikes went unfulfilled, as sluggish domestic consumption kept the central bank on hold. OPPORTUNITIES ABOUND Although the international market continues to be somewhat uncertain, we believe the international stock market presents significant opportunities for investors. Combining the higher growth rate of the international markets with our international team's focus on companies with growth acceleration, we believe there is a significant opportunity to deliver attractive performance in the coming year.

Compared to its peers, NT International Growth outperformed the average return of 20.46%* for the 63 funds in Lipper Inc.'s International Large Cap Growth Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks. On an absolute basis, all sectors the portfolio invested in posted positive returns, and all but one sector (consumer discretionary) showed double-digit gains. Favorable stock selection in six of 10 sectors accounted for the portfolio's outperformance relative to the benchmark. From a country perspective, Japan, the United Kingdom, and India, which was not represented in the benchmark, made the greatest overall contributions to the portfolio's relative performance. Stock selection in Japan and the United Kingdom was effective, as was an underweight in Japan. Despite its relatively small weighting, India had a strong impact on the portfolio's relative return. The worst country contributors to relative performance included the Netherlands, North America (U.S.-listed ADRs and Canadian securities), and South Korea. Our investments and an underweight hurt performance in the Netherlands, while our overweight in North America accounted for the lagging results. Our South Korean holdings posted a negative return for the reporting period, and the benchmark had no exposure to that market. FINANCIALS, INDUSTRIALS LED ALL SECTORS The financials sector, the largest weighting in the portfolio, made the greatest positive contribution to relative performance. Our overweight to Deutsche Boerse AG, the Germany-based owner of several securities exchanges, led to solid results for the diversified financial services area. In addition, our position in China Merchants Bank, an emerging-market investment not represented in the benchmark, boosted performance in the commercial banking segment, as the stock returned 142% during the reporting period.

In particular, our stocks in the electrical equipment industry performed well, including Q-Cells AG, the German manufacturer of solar cells, and Vestas Wind Systems, a Danish supplier of wind power solutions. Our information technology stocks also were strong contributors, led by Japan's Nintendo, a videogame manufacturer, which advanced 160% during the reporting period on strong sales of its Wii gaming system. Nintendo was the portfolio's top contributor for the reporting period. CONSUMER SECTOR LAGGED Despite posting a total return of 24.06% for the reporting period, the portfolio's consumer staples sector was the greatest laggard relative to the benchmark. Our stock selection and underweight in the food products industry and avoidance of the tobacco industry primarily accounted for the shortfall. The telecommunication services sector also detracted, primarily due to our slight overweight to the sector. OUTLOOK NT International Growth seeks companies located throughout the world, excluding the United States, exhibiting accelerating earnings and revenue growth. Our analysis indicates the outlook for large-cap growth companies remains favorable. The portfolio has broad exposure to high-quality growth companies in numerous markets, and we believe these companies will deliver solid returns, even during volatile market conditions.

The portfolio's benchmark, the MSCI EM Index, advanced 45.15%. Compared to its peers, NT Emerging Markets outperformed the average return of 41.98%* for the 257 funds in Lipper Inc.'s Emerging Markets Funds category. Strong global economic growth combined with a weak U.S. dollar helped generate strong 12-month performance among international stocks, particularly those from the world's emerging markets. Emerging market stocks significantly outperformed the developed markets, which, as measured by the MSCI EAFE Index, returned 17.30% for the reporting period. The portfolio's performance benefited from this trend, along with our stock selection across most market sectors. Overall, stock selection accounted for the portfolio's outperformance relative to the benchmark. On an absolute basis, all sectors the portfolio invested in posted positive returns and made positive contributions to performance. Compared with the benchmark, each of the portfolio's market sectors outperformed except materials, financials and health care. The portfolio also derived a portion of its returns from participating in several initial public offerings (IPOs). RUSSIA, INDIA, SOUTH KOREA OUTPERFORMED From a country perspective, Russia, India and South Korea had the greatest positive influence on the portfolio's relative performance. Stock selection was the key contributor in all three markets. Brazil and China detracted from the portfolio's relative performance, with stock selection accounting for the shortfall. TECH, ENERGY, CONSUMER DISCRETIONARY LED ALL SECTORS Good stock selection helped make the information technology sector the top contributor to the portfolio's relative performance. Our stock picks and allocation decisions were particularly strong in the semiconductor industry, where underweighting South Korea's Samsung Electronics, which faced waning demand in the memory chip market, proved effective.

Similarly, our favorable stock choices led to outperformance for the portfolio's consumer discretionary sector. For example, in the auto components industry, Nokian Renkaat Oyj, a position not represented in the benchmark, contributed strongly to relative performance. The Finnish tire manufacturer advanced on strong sales and profit growth, primarily in Russia. Another out-of-benchmark position, Parkson Retail Group, which operates a chain of department stores in China, benefited from the company's expansion plans and China's growing retail market. MATERIALS, FINANCIALS LAGGED The materials and financials sectors were the largest detractors to the portfolio's relative performance. This primarily was due to our underweighted positions in both sectors and to lagging stocks in the financials sector. The financials sector was the portfolio's largest, yet underweights and stock selection in the insurance and capital markets segments detracted from the portfolio's performance. The subprime mortgage market mess reverberated globally during the reporting period and dragged down holdings such as Shin Kong Financial Holding, a Taiwanese life insurer that acknowledged a portion of its fixed income portfolio was backed by U.S. subprime mortgages. In addition, not having any exposure to diversified financial services companies hurt the portfolio's results relative to the benchmark. OUTLOOK Focusing almost exclusively on equity securities of companies located in emerging market countries, we seek out companies with earnings and revenues growing at an improving rate. We will continue to select stocks based on extensive company-level research that focuses on identifying accelerating growth characteristics.

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 June 1, 2007 to November 30, 2007. 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. 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. - ------ 16 Expenses Paid Beginning Ending During Period* Account Value Account Value 6/1/07 - Annualized 6/1/07 11/30/07 11/30/07 Expense Ratio* NT International Growth -- Institutional Class Actual $1,000 $1,085.30 $5.59 1.07% Hypothetical $1,000 $1,019.70 $5.42 1.07% NT Emerging Markets -- Institutional Class Actual $1,000 $1,215.50 $7.94 1.43% Hypothetical $1,000 $1,017.90 $7.23 1.43% *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 183, 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. - ------ 20 NOTES TO FINANCIAL STATEMENTS NOVEMBER 30, 2007 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION -- American Century World 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 International Growth Fund (NT International Growth) and NT Emerging Markets Fund (NT Emerging Markets) (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 capital growth. The funds pursue this objective by investing primarily in equity securities of foreign companies. NT International Growth primarily invests in companies located in at least three developed countries (excluding United States). NT Emerging Markets invests at least 80% of its assets in securities of issuers in emerging market countries and companies that derive a significant portion of their business from emerging market countries. The funds are not permitted to invest in any securities issued by companies assigned by the Global Industry Classification Standard to 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 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 as determined by, or in accordance with procedures adopted by, the Board of Directors or its designee if such determination would materially impact a fund's net asset value. Certain other circumstances may cause the funds to use alternative procedures to 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 -- For financial reporting purposes, 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. Certain countries impose taxes on realized gains on the sale of securities registered in their country. The funds record the foreign tax expense, if any, on an accrual basis. The realized and unrealized tax provision reduces the net realized gain (loss) on investment transactions and net unrealized appreciation (depreciation) on investments, respectively. 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. EXCHANGE TRADED FUNDS -- The funds may invest in exchange traded funds (ETFs). ETFs are a type of index fund bought and sold on a securities exchange. An ETF trades like common stock and represents a fixed portfolio of securities designed to track the performance and dividend yield of a particular domestic or foreign market index. A fund may purchase an ETF to temporarily gain exposure to a portion of the U.S. or a foreign market while awaiting purchase of underlying securities. The risks of owning an ETF generally reflect the risks of owning the underlying securities they are designed to track, although the lack of liquidity on an ETF could result in it being more volatile. Additionally, ETFs have management fees, which increase their cost. 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. - ------ 21 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 foreign currency transactions and unrealized appreciation (depreciation) on translation of assets and liabilities in foreign currencies, 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. SECURITIES ON LOAN -- The funds may lend portfolio securities through their lending agent to certain approved borrowers in order to earn additional income. The funds continue to recognize any gain or loss in the market price of the securities loaned and record any interest earned or dividends declared. REPURCHASE AGREEMENTS -- The funds may enter into repurchase agreements with institutions that American Century Investment Management, Inc. (ACIM) 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. At this time, management has not identified any uncertain tax positions that would materially impact the financial statements. Accordingly, no provision has been made for federal or state income taxes. Interest and penalties associated with any federal or state income tax obligations, if any, are recorded as interest expense. DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on the ex-dividend date. Distributions from net investment income, if any, are generally declared and paid annually. Distributions from net realized gains, if any, are generally declared and paid twice per year. The funds may make distributions on a more frequent basis to comply with the distribution requirements of the Internal Revenue Code, in all events in a manner consistent with provisions of the 1940 Act. 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 ACGIM (the investment advisor), under which ACGIM 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 - ------ 22 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 International Growth and NT Emerging Markets include the assets of International Growth Fund and Emerging Markets Fund, respectively, two funds in a series issued by the corporation. The annual management fee schedule for NT International Growth ranges from 0.90% to 1.30%. The annual management fee schedule for NT Emerging Markets ranges from 1.05% to 1.65%. The effective annual management fee for NT International Growth and NT Emerging Markets for the year ended November 30, 2007 was 1.06% and 1.46%, respectively. ACGIM has entered into a Subadvisory Agreement with ACIM (the subadvisor) on behalf of the funds. The subadvisor makes investment decisions for the cash portion of the funds in accordance with the funds' investment objectives, policies and restrictions under the supervision of ACGIM and the Board of Directors. ACGIM pays all costs associated with retaining ACIM as the subadvisor of the funds. 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, ACGIM, the corporation's subadvisor, 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 Asset Allocation Portfolios, Inc. (ACAAP). ACAAP does not invest in the funds for purpose of exercising management or control. Beginning in December 2006, the funds are eligible to invest in a money market fund for temporary purposes, which is managed by J.P. Morgan Investment Management, Inc. (JPMIM). JPMIM is a wholly owned subsidiary of JPMorgan Chase & Co. (JPM). JPM is an equity investor in ACC. The funds have a bank line of credit agreement and securities lending agreement with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the funds and a wholly owned subsidiary of JPM. 3. INVESTMENT TRANSACTIONS Investment transactions, excluding short-term investments, for the year ended November 30, 2007, were as follows: NT International Growth NT Emerging Markets Purchases $70,196,786 $25,082,712 Proceeds from sales $57,648,047 $24,613,657 4. SECURITIES LENDING As of November 30, 2007, securities in NT International Growth and NT Emerging Markets valued at $2,919,428 and $1,642,441, respectively, 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 $3,016,347 and $1,660,981, respectively. The funds' 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 funds may be delayed or limited. - ------ 23 5. 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 0.40%. The funds did not borrow from the line during the year ended November 30, 2007. Effective December 12, 2007, the funds, along with certain other funds managed by ACIM or ACGIM, have a $500,000,000 unsecured bank line of credit agreement with Bank of America, N.A. (the Bank of America agreement). The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the Bank of America agreement bear interest at the Federal Funds rate plus 0.40%. 6. RISK FACTORS There are certain risks involved in investing in foreign securities. These risks include those resulting from future adverse political, social, and economic developments, fluctuations in currency exchange rates, the possible imposition of exchange controls, and other foreign laws or restrictions. Investing in emerging markets may accentuate these risks. NT Emerging Market's performance may be affected by investments in initial public offerings (IPOs). The impact of IPOs on a fund's performance depends on the strength of the IPO market and the size of the fund. IPOs may have less impact on a fund's performance as its assets grow. 7. FEDERAL TAX INFORMATION The tax character of distributions paid during the year ended November 30, 2007 and the period May 12, 2006 (fund inception) through November 30, 2006 were as follows: NT International Growth NT Emerging Markets 2007 2006 2007 2006 DISTRIBUTIONS PAID FROM Ordinary income $138,053 -- $132,946 -- 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. As of November 30, 2007, the components of distributable earnings on a tax-basis and the federal tax cost of investments were as follows: NT International NT Emerging Growth Markets Federal tax cost of investments $58,648,867 $22,613,143 =========== =========== Gross tax appreciation of investments $13,140,633 $7,629,439 Gross tax depreciation of investments (617,795) (294,462) ----------- ----------- Net tax appreciation (depreciation) of investments $12,522,838 $7,334,977 =========== =========== Net tax appreciation (depreciation) on translation of assets and liabilities in foreign currencies $(45,961) $(81,208) ----------- ----------- Net tax appreciation (depreciation) $12,476,877 $7,253,769 =========== =========== Undistributed ordinary income $1,138,429 $2,306,135 Accumulated long-term gains $864,531 $1,821,253 Capital loss deferrals $(61,065) -- Currency loss deferrals -- $(4,715) - ------ 24 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 on investments in passive foreign investment companies. The capital and currency loss deferrals listed on the previous page for the funds represent net capital and foreign currency losses incurred in the one-month period ended November 30, 2007. The funds have elected to treat such losses as having been incurred in the following fiscal year for federal income tax purposes. 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. Management has concluded that the adoption of FIN 48 will not materially impact the financial statements. 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 that adopting FAS 157 will have on the financial statement disclosures. 9. OTHER TAX INFORMATION (UNAUDITED) The following information is provided pursuant to provisions of the Internal Revenue Code. The funds hereby designate up to the maximum amount allowable as qualified dividend income for the fiscal year ended November 30, 2007.

See Notes to Financial Statements. - ------ 27 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Directors and Shareholders, American Century World Mutual Funds, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of NT International Growth Fund and NT Emerging Markets Fund (the "Funds"), two of the mutual funds comprising American Century World Mutual Funds, Inc., as of November 30, 2007, and the related statements of operations for the year then ended, and the statements of changes in net assets and the financial highlights for the year ended November 30, 2007 and the period May 12, 2006 (fund inception) to November 30, 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 November 30, 2007, 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 of American Century World Mutual Funds, Inc. as of November 30, 2007, the results of their operations for the year then ended, and the changes in their net assets and the financial highlights for the year ended November 30, 2007 and the period May 12, 2006 (fund inception) to November 30, 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. Those listed as interested directors are "interested" primarily by virtue of their engagement as directors and/or officers of, or ownership interest in, American Century Companies, Inc. (ACC) or its wholly owned, direct or indirect, subsidiaries, including the funds' investment advisor, American Century Global Investment Management, Inc. (ACGIM) or American Century Investment Management, Inc. (ACIM); the funds' principal underwriter, American Century Investment Services, Inc. (ACIS); and the funds' transfer agent, American Century Services, LLC (ACS). The other directors (more than three-fourths of the total number) are independent; that is, they have never been employees, directors or officers of, and have no financial interest in, ACC or any of its wholly owned, direct or indirect, subsidiaries, including ACGIM, ACIM, ACIS, and ACS. The directors serve in this capacity for seven registered investment companies in the American Century family of funds.

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.
