Contents Letter to shareholders 1 Investment adviser's report 2 The value of a long-term perspective 3 Preparing for a healthy harvest: Renewed interest in dividends 6 Investment portfolio 12 Financial statements 19 Fund Directors, Advisory Board and other officers 32 Fund results in this report were calculated for Class A shares at net asset value (without a sales charge) unless otherwise indicated. Since this shareholder report is for the Fund's fiscal year ended April 30, 2003, most results in this report are measured as of that date. For example, for the one-year period ended April 30, 2003, the Fund was down 13.36%. We also report returns with all distributions reinvested for periods ended March 31, 2003 (the most recent calendar quarter), with and without payment of the 5.75% maximum sales charge at the beginning of the stated periods. Here are both sets of results: Class A shares, for periods ended March 31, 2003 1 year 5 years 10 years Average annual compound return, with maximum sales charge -26.37% -1.89% + 9.38% Average annual compound return, at net asset value -21.88% -0.72% +10.02% Results for other share classes can be found on page 31. For the most current investment results, please refer to americanfunds.com. Please see page 34 for important information about other share classes. Figures shown are past results and are not predictive of future results. Share price and return will vary, so you may lose money. Investing for short periods makes losses more likely. Investments are not FDIC-insured, nor are they deposits of or guaranteed by a bank or any other entity. Fellow shareholders: Your Fund's 2003 fiscal year, which ended on April 30, was one of the most difficult for common stock investments in Washington Mutual's 51-year history. Both the Fund and the stock market suffered from terrorism's adverse effects on American business here and around the world. As a result, during the fiscal period from April 30, 2002 to April 30, 2003, the value of an investment in Washington Mutual declined by 13.4%, assuming reinvestment of income dividends totaling 54 cents a share and a long-term capital gain distribution of 4 cents a share. These results were almost exactly in line with the unmanaged Standard & Poor's 500 Composite Index, which declined by 13.3%, with dividends reinvested. On page 2, you will find more details in a discussion by our investment adviser, Capital Research and Management Company. Over longer periods, your Fund's adherence to strict investment standards, coupled with experienced management, has produced above-average returns. Longer term results reflect a stronger relative performance as follows: Average annual compound returns 1 year 5 years 10 years Lifetime Washington Mutual -13.4% +0.8% +10.9% +12.7% S&P 500 -13.3% - 2.4% +9.7% +11.2% The recent increased emphasis on dividends argues well for your Fund's performance in both the near and long term. Over the years, Washington Mutual's return has been helped by its focus on the dividend-paying abilities of the companies in the Fund's portfolio. Reinvestment of income has always contributed significantly to Washington Mutual's total return, and should continue to be very important in future years. Earlier this year, many of the companies in the Fund's portfolio urged support for proposals in Congress to reduce or eliminate taxation of dividends. The relief bill signed by President Bush on May 28, 2003 has already favorably affected the share prices of many strong dividend-paying stocks. The new 15% maximum tax rate on qualified dividend income to individuals is retroactive to January 1, 2003. The maximum tax on long-term capital gains is now 15% and applicable to gains realized on and after May 6, 2003. Since our last report to you six months ago, eight new companies have appeared in the portfolio: Automatic Data Processing, Carnival, CenturyTel, EOG Resources, NiSource, Temple-Inland, Tyco International, and Unilever. Seven securities have been eliminated: CSX, Eastman Kodak, Ford Motor, Goodyear Tire & Rubber, Harris, MGIC Investment, and Royal Dutch Petroleum. Pharmacia no longer appears because of its merger into Pfizer. At fiscal year-end, the number of companies held totaled 161. Since the conclusion of the war in Iraq - near the close of your Fund's fiscal year - share prices have rebounded considerably and consumer confidence has improved. With a continued low interest rate environment, your management is hopeful that a steady improvement in business conditions will ensue. We encourage you to work with your financial adviser and employer to review the many improved options for tax deferred savings that have become available to you over the past two years. This year you can contribute $12,000 to your 401(k), 403(b), or 457 account. This amount increases $1,000 each year through 2006. Those of you 50 and older can add $2,000 to your company retirement plan beyond the general contribution limit. If your employer offers a SIMPLE IRA, you can defer up to $8,000 in 2003. This amount increases $1,000 for each of the next two years. Contribution limits on IRAs have increased to $3,000 in 2002, $4,000 in 2005, and $5,000 in 2008. Individuals over 50 can add $500 more to their IRA contribution and $1,000 more beginning in 2006. A powerful savings tool that exists for educational savings is CollegeAmerica, a Section 529 plan that provides a tax-advantaged way to help meet the increasing cost of higher education. We are pleased to welcome the many new shareholders who have joined us during the turbulent investment environment over the past year. Questions and comments from shareholders are always welcome. Cordially, (signature) James H. Lemon, Jr., Chairman of the Board (signature) Harry J. Lister, Vice Chairman of the Board (signature) Jeffrey L. Steele, President of the Fund June 11, 2003 (graphic Washington Monument) Investment adviser's report During fiscal 2003, share prices suffered from concerns about the impact of turmoil in the Middle East, volatile oil prices, unusually harsh winter weather and a sluggish U.S. economy. Continued media coverage of corporate malfeasance and accounting scandals also dampened investors' enthusiasm for stocks. Even the quality equities held by Washington Mutual Investors Fund were affected by these events. In this negative environment, the value of an investment in the Fund, with dividends reinvested, fell 13.4%, about the same as the unmanaged Standard & Poor's 500 Composite Index, which declined 13.3%, and the Lipper Growth and Income Fund Index, which fell 13.3%. The Fund outpaced the Lipper Large-Cap Value Fund Index, which slipped 15.1%. These results placed the Fund in the top 26% (308th of 1,191) of all growth-and-income funds for the year. Over long periods, the Fund did even better; Washington Mutual ranked in the top 16% (107th of 704) of all growth-and-income funds for the past five years, and in the top 10% (22nd of 223) for the past 10 years. It was the first time in the Fund's 51-year history that the broad stock market, as represented by the S&P 500, showed a decline for three consecutive fiscal years. For investors concerned with preserving their capital in a bear market, the Fund's record over that period may be even more important than its one-year results. A shareholder invested in the Fund for the three years ended April 30, 2003, for example, would have experienced a small decline of 2.4%, with dividends reinvested. This is a sharp contrast with the 22.3% decline of the average growth-and-income fund and the 16.5% loss of the average large-cap value fund, according to Lipper. The S&P 500 fared even worse, showing a loss of 34.1%, and the technology-heavy Nasdaq Composite Index tumbled 62.1%. (These returns are cumulative over the three-year period.) The Fund's highly disciplined approach to investing, which focuses primarily on companies with strong balance sheets and consistent records of paying dividends, has served as a buffer against stock market declines. This approach again proved its merit in difficult markets; the Fund has done better than the S&P 500 in each of the 12 major stock market declines since the Fund's inception in 1952. The economic picture The U.S. economy completed its sixth quarter of recovery from recession as of March 31, 2003, but its performance in the past two quarters has decelerated. Growth in consumer spending slowed in the first quarter of this year and corporations cut capital spending. The economy grew at a 1.9% annual rate in the first quarter of 2003, barely up from a 1.4% pace in the fourth quarter of 2002. For the full calendar year of 2002, the economy grew 2.4%. Concerns about the war in Iraq and rising oil prices hurt. On the positive side, the housing market remained healthy and interest rates hovered at their lowest levels in decades. The Fund's investments The fiscal year began with the stock market slipping to a new low in July; it rallied in August and tumbled in September, bottoming on October 9. Stocks fell in January, February and early March but rallied after the coalition forces' success in the war in Iraq. As a result, April 2003 - the last month of the fiscal year - turned out to be the best month of the period for Washington Mutual, with a return of almost 8%. The Fund's six largest industry positions at fiscal year-end as a percentage of net assets were: Banks (10.8%), Pharmaceuticals (9.7%), Electric utilities (8.0%), Oil & gas (7.6%), Diversified telecommunication services (6.8%), and Diversified financial services (5.2%). One positive note during the year was the renewed interest in dividends. More than 80 companies in the S&P 500 increased their dividends in the first four months of 2003, and five companies initiated dividend payments. Even the software giant Microsoft began paying a small dividend. More dividend-paying companies potentially means more investment opportunities for Washington Mutual, as it increases the number of companies from which the Fund's managers can select. We will continue our strategy of seeking to invest in quality companies that meet strict standards of financial soundness, including a consistent record of paying dividends. This approach has served the Fund well in all kinds of markets, and we believe it will continue to do so in the years ahead. - - Capital Research and Management Company The value of a long-term perspective (graph showing growth of a $10,000 investment in Consumer Price Index, Average Savings Institution, Washington Mutual with dividends taken in cash, S&P 500 with dividends reinvested, and Washington Mutual with dividends reinvested) How a $10,000 investment in Washington Mutual Investors Fund grew This chart shows how a $10,000 investment grew between July 31, 1952, when the Fund began operations, and April 30, 2003. As you can see, that $10,000 investment in Washington Mutual, with all distributions reinvested, would have grown to $4,050,310. Over the same period, that $10,000 would have grown to $2,138,513 in the unmanaged Standard & Poor's 500 Composite Index of U.S. common stocks. According to the Consumer Price Index, it now requires $68,839 to purchase what $10,000 would have bought on July 31, 1952. In the average savings institution, $10,000 with interest compounded would have grown to $126,594. The year-by-year progress of the $10,000 investment is summarized in the table below the chart. You can use those figures to estimate how the value of your own holdings has grown. Let's say, for example, that you have been reinvesting all your distributions and want to know how your investment has done since April 30, 1993. At that time, according to the table, the value of the investment illustrated here was $1,442,389. Since then it has gone up nearly threefold to $4,050,310. Thus, in the same 10-year period, the value of your 1993 investment - - regardless of its size - has increased nearly threefold.

There is no sales charge on dividends or capital gain distributions that are reinvested in additional shares. The maximum sales charge was 8.5% prior to July 1, 1988. Results shown do not take into account income or capital gain taxes. /2/ Total value includes reinvested dividends of $1,142,522 and reinvested capital gain distributions of $1,962,596. /3/ Capital value includes reinvested capital gain distributions of $357,586 but does not reflect income dividends of $236,178 taken in cash. /4/ With all interest compounded.

Crops are still harvested today - a testament to Washington's legacy. Preparing for a healthy harvest: Renewed interest in dividends "Dividends are the ultimate proof that stocks are not just pieces of paper but represent ownership in real businesses." - - Bernard J. Nees, the Fund's founder During the past two decades, the appeal of dividends faded as many investors - and more than a few companies - focused solely on growth. Now the trend seems to be reversing, and the market is rediscovering the important role of dividends. In late May, Congress lowered the maximum Federal tax rate on qualified dividend income to 15% from what had been 30% or higher for many investors. When a company pays a dividend, shareholders receive a reward they can put in their pockets. If a company doesn't pay a dividend, shareholders are rewarded only if the stock price has gone up and they sell the stock. What's more, when the market is stagnant or declining, share prices of dividend payers have tended to be more stable than those of non-payers. The reliable return from dividend income can help to provide something like a "floor" - a level where investors will tend to hold shares even if prospects for price appreciation are murky. These advantages add up. Over the past 50 calendar years, dividends have accounted for roughly a third of the average annual compound return from an investment in stocks, as measured by Standard & Poor's 500 Composite Index. Much of that contribution reflects the advantage of compounding. Income from dividends can earn more income, and that income can earn income, and so on. Your Fund's tough standard for dividends Washington Mutual Investors Fund has always emphasized companies that share profits with shareholders. The Fund's rigorous standards require the vast majority of its holdings to have strong histories of paying dividends - and paying them from earnings, as opposed to using borrowed money.These standards are based on rules originally established in the 1930s by the United States District Court for the District of Columbia to protect trust funds from investing in high-risk companies. The logic of the dividend standard clearly remains sound: investing primarily in companies with established dividend records helped the Fund avoid owning shares in seemingly fast-growing companies that recently made headlines but proved to be built of straw. Proof of a company's success "If a company has a long record of paying dividends, it has usually been well-managed," says Steve Bepler, one of the Fund's eight portfolio counselors. "Furthermore, if the dividend has been increased regularly, you don't need a balance sheet to know the company's finances are probably in good shape. On the other hand, if a company cuts its dividend, it might be in serious financial trouble. If it doesn't pay one at all, there had better be a compelling reason." Research analyst Cathy Kehr agrees: "A good company tends to have money left over after paying the bills. If there's nothing left, it's usually not a very good business." Dividend payouts vary. Mature companies in industries such as utilities and banking, where research and development costs are relatively small, tend to pay out a higher percentage of earnings. New companies that are still expanding rapidly often don't pay dividends at all. Most companies fall somewhere in between. (Side Bar) The Fund's holdings have long histories of paying dividends At December 31, 2002, there were 169 companies in the Fund's portfolio: 131 had paid uninterrupted dividends for at least 25 years 103 had paid uninterrupted dividends for at least 50 years 56 had paid uninterrupted dividends for at least 75 years 24 had paid uninterrupted dividends for at least 100 years 24% increased their dividends during 2002 Two holdings were among the first corporations in the United States to pay dividends and have done so for more than 200 years: - - The Bank of New York (since 1785) - - FleetBoston Financial (since 1791, by its predecessor company) The Fund's portfolio, listed on pages 12-18, shows when each holding began paying dividends. (End of Side Bar) The first dividends ever paid were clearly too high: They entailed distributing not just the proceeds of voyages by British and Dutch ships in the 16th century, but also the ships themselves. The inefficiency of having to build new ships for every expedition was soon noted, and dividends became distributions of profits alone. Research analyst Will Robbins says it remains a good idea to be wary of dividends that seem too high or that even occasionally exceed a company's earnings. "They probably aren't sustainable and will be cut eventually," he says." In the case of companies paying high dividends, the worry is that they may be robbing Peter to pay Paul and may not be able to maintain their competitive position or their credit rating." A very small dividend can also be a danger sign, says lead portfolio counselor Jim Dunton. "It can mean the company's management may be too aggressive with expansion plans, and that the company thinks its own shareholders aren't clever enough to reinvest the money wisely. Of course, the other extreme - paying out nearly all profits - can mean that the company is saying its own managers aren't clever enough to use the money wisely." Putting the dividend standard to work Companies that find the right balance between providing for income (dividends) and for growth (share price appreciation) are ideal for Washington Mutual. The Fund seeks both, which is one of the reasons why its returns have been relatively stable over time. Regular income from dividends can serve as a buffer against stock market declines, which helps explain why the Fund has outpaced the S&P 500 during every one of the 12 major stock market declines since the Fund's inception in 1952. At the same time, the long-term historical trend toward higher stock market prices makes it possible to outpace inflation. (Call Out) "We want to know how the business generates earnings and if they've been stable or cyclical." - Jim Lovelace (End of Call Out) The Fund's dividend requirement is a key discipline, Jim Dunton says. "There are plenty of stocks that might be attractive for us short term. But our focus on stocks with solid long-term dividend records makes it more likely the Fund can keep on achieving its goals of providing a higher yield than the S&P 500 average and rewarding shareholders who reinvest their capital gains with more cash income every year." When evaluating an eligible company's future dividend prospects, the Fund's managers study earnings, because a company can't pay out more than it takes in - - at least not for long. Portfolio counselor Jim Lovelace says, "We want to know how the business generates earnings and if they've been stable or cyclical. Then we look at how much has been returned to investors each year as dividends, with special attention paid to periods of stress for the company or its industry." Of course, a rising dividend is typically a plus. Portfolio counselor Tim Armour notes, "If a company increases the dividend, it increases stability of the return. If it cuts the dividend, it decreases the stability of the return."

(End of Side Bar) Percentage of S&P 500 stocks that paid dividends (Bar Chart showing that the percentage of S&P 500 stocks that padi dividends declined from 90.8 in 1983 to 70.2 in 2002) Among the most attractive opportunities are companies where the dividend amounts have grown while the percentage of earnings used to pay them has remained about the same. (Call Out) "If a company increases the dividend, it increases the stability of the return." - - Tim Armour (End of Call Out) Where did dividends go Since the beginning of calendar 2003, more than 80 S&P 500 companies have increased their dividends or started paying dividends for the first time. This appears to be a welcome reversal of the trend over the past two decades, when the percentage of dividend-paying companies included in that index had fallen from around 90% to just 70%. The average dividend yield on the S&P 500 dipped below 3% in 1991 and continued to decline throughout most of the 1990s. One key reason is that the composition of the market index changed to include a number of technology companies that had yet to pay dividends. Tax law changes were also a factor. In 1987, Congress abolished an exemption that had allowed individuals to earn up to $100 a year in dividends, tax-free ($200 for couples filing jointly). In 1998, the top tax rate paid on capital gains was lowered to 20% versus 39.6% on dividends, which tended to discourage paying dividends and encourage selling shares for profits rather than holding them for income. Another problem was the greatly increased use of stock option grants (opportunities to buy shares at a fixed price) as executive compensation in the 1990s. As portfolio counselor Alan Berro notes, "The theory was that having managers own shares would align their interests with the other shareholders. The problem was that option holders only benefited if the stock price went up. So the incentive was to reinvest earnings in hopes that the business would grow and the options would be worth more. There was no incentive to pay dividends." Stock buybacks contributed, too. By purchasing their own shares on the open market - therefore reducing the supply - companies believed they could increase per share earnings and, in turn, increase their share prices. Shareholders would be rewarded with a capital gain instead of a dividend - and be able to pay lower taxes on the "reward." In many cases, though, shares bought back were used to fulfill options grants at lower prices than they cost the company. Low interest rates also played a role, in the latter half of the 1990s. Dividend yields didn't have to be very high to compete with yields from bonds and other competitive investments. And, of course, in the heady days when the market was gaining 15% or 20% a year, the relatively small contribution made by dividends didn't seem very important. Perhaps the most important reason, however, was overconfidence on the part of some corporate management teams, thinking they could provide higher rewards to their shareholders by reinvesting most or all of their earnings instead of paying them out as dividends. "Companies shouldn't pay dividends if they have a better use for the cash than their shareholders do, but not many companies meet that standard. Most companies don't have the growth prospects to justify keeping all the cash," observes Alan Berro. Such pressures to reinvest earnings rather than pay dividends led some companies to make bad decisions, acquiring businesses they couldn't absorb and expanding beyond their capabilities. The results were obvious only when the economy turned downward and stock prices plummeted. "When the tide went out this time, we found that there were a lot of naked swimmers," notes research analyst Greg Johnson. A brighter future The recent market downturn, a number of widely reported accounting scandals and new Federal laws focused on corporate governance standards are causing corporations to re-examine their business practices and decisions. Some are rediscovering that paying dividends attracts long-term investors. Because long-term investors are less concerned with short-term results, the stock prices of dividend payers tend to fluctuate less. In late May, Congress strengthened the role of dividends by cutting the maximum Federal tax rate on qualified dividend income to 15%. The rate cut is expected to make dividend income far more appealing to investors. It should also encourage corporations to further examine their dividend-paying policies. Notably, a number of stalwart non-payers - such as Microsoft - have changed their tunes and begun to pay dividends, albeit tiny ones. "A lot of successful technology companies are sitting on large cash balances," portfolio counselor Dale Harvey points out. Other industries may also be reaching the point in their life cycles where they are more likely to pay dividends. Portfolio counselor Steve Bepler suggests that cable television companies and wireless telephone companies, once they have their networks in place, tend to generate a lot of cash but don't need much to maintain their businesses.

(Side Bar) How to make the most of your dividends from the Fund Dividends paid by a mutual fund that invests in stocks represent dividends from fund holdings, minus the fund's operating expenses. Washington Mutual Investors Fund helps you by keeping its expenses low, only about half the average for comparable funds (0.67% versus 1.25%, in calendar 2002). By reinvesting your Fund dividends - as more than 90% of the Fund's shareholders do - you can gain the additional advantage of compounding. That can make a tremendous difference in long-term results.

(End of Side Bar) When a company begins paying dividends, its days of innovation aren't over. Many pharmaceutical companies, for example, spend significantly on developing new drugs but still manage to pay strong dividends. Once a popular drug has been introduced, manufacturing costs tend to be lower and profits tend to be larger. Because the Fund's investment professionals have spent many years studying companies, there are occasions when experience tells them that a company may not be making the best use of excess cash. "If we feel a company can't reinvest profits for high returns, we may encourage the company to increase its dividend - - or to start paying one, if it doesn't already," says Greg Johnson. More companies paying dividends potentially means more investment opportunities for Washington Mutual over time, because it increases the number of companies from which the Fund's managers can select. "This is the beginning of a major change," says Cathy Kehr. "I believe more companies will begin to pay dividends. More of those that already do pay them are likely to increase them. We think the market's coming Washington Mutual's way."

Organization and significant accounting policies Organization - Washington Mutual Investors Fund (the "Fund") is registered under the Investment Company Act of 1940 as an open-end, diversified management investment company. The Fund's investment objective is to produce current income and to provide an opportunity for growth of principal consistent with sound common stock investing. The Fund offers 14 share classes consisting of four retail share classes, five CollegeAmerica savings plan share classes and five retirement plan share classes. The CollegeAmerica savings plan share classes (529-A, 529-B, 529-C, 529-E and 529-F) are sponsored by the Commonwealth of Virginia and can be utilized to save for college education. The five retirement plan share classes (R-1, R-2, R-3, R-4 and R-5) are sold without any sales charges and do not carry any conversion rights. The Fund's share classes are described below: Initial Contingent deferred Share class sales charge sales charge upon redemption Conversion feature Classes A and 529-A Up to 5.75% None (except 1% for certain None redemptions within one year of purchase within an initial sales charge) Classes B and 529-B None Declines from 5% to zero for Classes B and 529-B convert to redemptions within six classes A and 529-A, respectively, years of purchase after eight years Class C None 1% for redemptions within Class C converts to Class F one year of purchase after 10 years Class 529-C None 1% for redemptions within None one year of purchase Class 529-E None None None Classes F and 529-F None None None Classes R-1, R-2, R-3, R-4 and R-5 None None None Holders of all share classes have equal pro rata rights to assets, dividends and liquidation. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses ("class-specific fees and expenses"), primarily due to different arrangements for distribution, administrative and shareholder services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each class. Significant accounting policies - The financial statements have been prepared to comply with accounting principles generally accepted in the United States of America. These principles require management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates. The following is a summary of the significant accounting policies followed by the Fund: Security valuation - Equity securities are valued at the official closing price of, or the last reported sale price on, the exchange or market on which such securities are traded as of the close of business or, lacking any sales, at the last available bid price. Prices for each security are taken from the principal exchange or market in which the security trades. Fixed-income securities are valued at prices obtained from a pricing service. However, where the investment adviser deems it appropriate, they will be valued at the mean quoted bid and asked prices or at prices for securities of comparable maturity, quality and type. Short-term securities maturing within 60 days are valued at amortized cost, which approximates market value. The ability of the issuers of the debt securities held by the Fund to meet their obligations may be affected by economic developments in a specific industry, state or region. Securities and other assets for which representative market quotations are not readily available are valued at fair value as determined in good faith by authority of the Fund's Board of Directors. Security transactions and related investment income - Security transactions are recorded by the Fund as of the date the trades are executed with brokers. Realized gains and losses from security transactions are determined based on the specific identified cost of the securities. Dividend income is recognized on the ex-dividend date and interest income is recognized on an accrual basis. Class allocations - Income, fees, and expenses (other than class-specific fees and expenses) and realized and unrealized gains and losses are allocated daily among the various share classes based on their relative net assets. Class-specific fees and expenses, such as distribution, administrative and certain shareholder services, are charged directly to the respective share class. Dividends and distributions to shareholders - Dividends and distributions paid to shareholders are recorded on the ex-dividend date. 2. Federal income taxation and distributions The Fund complies with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and intends to distribute substantially all of its net taxable income and net capital gains each year. The Fund is not subject to income taxes to the extent such distributions are made. Distributions - Distributions paid to shareholders are based on net investment income and net realized gains determined on a tax basis, which may differ from net investment income and net realized gains for financial reporting purposes. These differences are due primarily to differing treatment for items such as capital losses related to sales of securities within 30 days of purchase; expenses deferred for tax purposes; cost of investments sold; and net capital losses. The fiscal year in which amounts are distributed may differ from the year in which the net investment income and net realized gains are recorded by the Fund. As of April 30, 2003, the cost of investment securities for Federal income tax purposes was $46,819,873,000. During the year ended April 30, 2003, the Fund reclassified $3,000 from additional paid-in capital and $544,000 from undistributed net investment income to accumulated net realized loss to align financial reporting with tax reporting. As of April 30, 2003, the components of distributable earnings on a tax basis were as follows: (dollars in thousands) Undistributed net investment income $ 111,997 Short-term and long-term capital loss deferrals (556,652) Gross unrealized appreciation on investment securities 6,552,748 Gross unrealized depreciation on investment securities (5,140,986) Short-term and long-term capital loss deferrals above include capital losses of $556,652,000, that were realized during the period November 1, 2002 through April 30, 2003.

Fees and transactions with related parties Business management services - The Fund has a business management agreement with Washington Management Corporation (WMC). Under this agreement, WMC provides services necessary to carry on the Fund's general administrative and corporate affairs. These services include all executive personnel, clerical staff, office space and equipment, certain accounting and recordkeeping facilities, arrangements for and supervision of shareholder services, and Federal and state regulatory compliance. Under the agreement, all expenses chargeable to the Class A shares of the Fund, including compensation to the business manager, shall not exceed 1% of the average net assets of the Fund on an annual basis. The agreement provides for monthly fees, accrued daily, based on a declining series of annual rates beginning with 0.175% on the first $3 billion of daily net assets and decreasing to 0.040% of such assets in excess of $55 billion. For the year ended April 30, 2003, the business management services fee was equivalent to an annualized rate of 0.091% of average daily net assets. Johnston, Lemon & Co. Incorporated (JLC), a wholly owned subsidiary of The Johnston-Lemon Group, Incorporated (JLG), earned $601,000 on its retail sales of shares and distribution plan of the Fund and received no brokerage commissions resulting from the purchases and sales of securities for the investment account of the Fund. Investment advisory services - Capital Research and Management Company (CRMC), the Fund's investment adviser, is the parent company of American Funds Service Company (AFS), the Fund's transfer agent, and American Funds Distributors, Inc. (AFD), the principal underwriter of the Fund's shares. The Investment Advisory Agreement with CRMC provides for monthly fees accrued daily. These fees are based on a declining series of annual rates beginning with 0.225% on the first $3 billion of daily net assets and decreasing to 0.185% on such assets in excess of $55 billion. For the year ended April 30, 2003, the investment advisory services fee was equivalent to an annualized rate of 0.199% of average daily net assets. Class-specific fees and expenses - Expenses that are specific to individual share classes are accrued directly to the respective share class. The principal class-specific fees and expenses are described below: Distribution services - The Fund has adopted plans of distribution for all share classes, except for Class R-5. Under the plans, the Board of Directors approves certain categories of expenses that are used to finance activities primarily intended to sell Fund shares. The plans provide for annual expenses, based on a percentage of average daily net assets, ranging from 0.25% to 1.00% as noted below. In some cases, the Board of Directors has approved expense amounts lower than plan limits. Share class Currently approved limits Plan limits Class A 0.25% 0.25% Class 529-A 0.25 0.50 Classes B and 529-B 1.00 1.00 Classes C, 529-C and R-1 1.00 1.00 Class R-2 0.75 1.00 Classes 529-E and R-3 0.50 0.75 Classes F, 529-F and R-4 0.25 0.50 All share classes may use up to 0.25% of average daily net assets to pay service fees, or to compensate AFD for paying service fees, to firms that have entered into agreements with AFD for providing certain shareholder services. Expenses in excess of these amounts, up to approved limits, may be used to compensate dealers and wholesalers for shares sold. For classes A and 529-A, the Board of Directors has also approved the reimbursement of dealer and wholesaler commissions paid by AFD for certain shares sold without a sales charge. Each class reimburses AFD for amounts billed within the prior 15 months but only to the extent that the overall annual expense limit of 0.25% is not exceeded. As of April 30, 2003, there were no unreimbursed expenses subject to reimbursement for classes A or 529-A. Transfer agent services - The Fund has a transfer agent agreement with AFS for classes A and B. Under this agreement, these share classes compensate AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for transfer agent services provided to all other share classes from the administrative services fees paid to CRMC described below. Administrative services - The Fund has an administrative services agreement with CRMC to provide transfer agent and other related shareholder services for all classes of shares other than classes A and B. Each relevant class pays CRMC annual fees of 0.15% (0.10% for Class R-5) based on its respective average daily net assets. Each relevant class also pays AFS additional amounts for certain transfer agent services. CRMC and AFS may use these fees to compensate third parties for performing these services. During the start-up period for classes R-1, R-2, R-3 and R-4, CRMC has voluntarily agreed to pay a portion of these fees. Each 529 share class is subject to an additional annual administrative services fee of 0.10% of its respective average daily net assets; this fee is payable to the Commonwealth of Virginia for the maintenance of the CollegeAmerica plan. Although these amounts are included with administrative services fees in the accompanying financial statements, the Commonwealth of Virginia is not considered a related party. Administrative services fees are presented gross of any payments made by CRMC. Expenses under the agreements described above for the year ended April 30, 2003, were as follows (dollars in thousands): Administrative services Commonwealth of Distribution Transfer agent CRMC administrative Transfer agent Virginia administrative Share class services services services services services Class A $105,879 $47,769 Not applicable Not applicable Not applicable Class B 12,503 1,637 Not applicable Not applicable Not applicable Class C 9,033 | $1,354 $426 Not applicable Class F 1,582 | 949 217 Not applicable Class 529-A 147 | 188 20 $125 Class 529-B 320 | 48 20 32 Class 529-C 424 Included in 64 20 42 Class 529-E 25 administrative 7 1 5 Class 529-F 2 services 1 -<F1> 1 Class R-1 22 | 3 6 Not applicable Class R-2 205 | 41 157 Not applicable Class R-3 180 | 54 58 Not applicable Class R-4 38 | 23 6 Not applicable Class R-5 Not applicable | 198 5 Not applicable Total $130,360 $49,406 $2,930 $936 $205 <FN> <F1> Amount less than one thousand. </FN> Deferred Directors' and Advisory Board compensation - Since the adoption of the deferred compensation plan in 1994, Independent Directors and Advisory Board members may elect to defer the cash payment of part or all of their compensation. These deferred amounts, which remain as liabilities of the Fund, are treated as if invested in shares of the Fund or other American Funds. These amounts represent general, unsecured liabilities of the Fund and vary according to the total returns of the selected Funds. Directors' and Advisory Board fees in the accompanying financial statements include the current fees (either paid in cash or deferred) and the net increase or decrease in the value of the deferred amounts.

(the "Fund") at April 30, 2003, and the results of its operations, the changes in its net assets and its financial highlights for each of the periods presented in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit 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, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities owned at April 30, 2003 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. (signature PricewaterhouseCooper) Los Angeles, California May 30, 2003 Tax information (unaudited) We are required to advise you within 60 days of the Fund's fiscal year-end regarding the Federal tax status of certain distributions received by shareholders during such fiscal year. During the fiscal year ended April 30, 2003, the Fund paid a long-term capital gain distribution of $75,983,000. As a result of recent tax legislation, individual shareholders are now eligible for reduced tax rates on qualified dividend income received during 2003. For purposes of computing the dividends eligible for reduced tax rates, all of the dividends paid by the Fund from net investment income from January 1 through the end of the Fund's fiscal year are considered qualified dividend income. Corporate shareholders may exclude up to 70% of qualifying dividends received during the year. For purposes of computing this exclusion, all of the dividends paid by the Fund from net investment income represent qualifying dividends. Certain states may exempt from income taxation that portion of the dividends paid from net investment income that was derived from direct U.S. Treasury obligations. For purposes of computing this exclusion, 1% of the dividends paid by the Fund from net investment income were derived from interest on direct U.S. Treasury obligations. Dividends and distributions received by retirement plans such as IRAs, Keogh-type plans and 403(b) plans need not be reported as taxable income. However, many retirement plan trusts may need this information for their annual information reporting. Since the information above is reported for the Fund's fiscal year and not the calendar year, shareholders should refer to their Form 1099-DIV or other tax information which will be mailed in January 2004 to determine the calendar year amounts to be included on their 2003 tax returns. Shareholders should consult their tax advisers.

Class A shares are subject to a 5.75% maximum up-front sales charge that declines for accounts of $25,000 or more. Other share classes, which are generally not available for certain employer-sponsored retirement plans, have no up-front sales charges but are subject to additional annual expenses and fees. Annual expenses for Class B shares were 0.78% higher than for Class A shares; Class B shares convert to Class A shares after eight years of ownership. If redeemed within six years, Class B shares may also be subject to a contingent deferred sales charge (CDSC) of up to 5% that declines over time. Class C shares were subject to annual expenses 0.84% higher than those for Class A shares and a 1% CDSC if redeemed within the first year after purchase. Class C shares convert to Class F shares after 10 years. Class F shares, which are available only through certain fee-based programs offered by broker-dealer firms and registered investment advisers, had higher annual expenses (by 0.07%) than did Class A shares, and an annual asset-based fee charged by the sponsoring firm. Expenses are deducted from income earned by the Fund. As a result, dividends and investment results will differ for each share class.
