Fellow shareholders: (Photograph of Statue, same as cover, cropped) While inflationary pressures have been moderate, they have prompted the Federal Reserve Board to increase the federal funds rate eight times in the past 12 months. In a recent comment, the Federal Reserve Board noted an increase in pricing power by vendors. Thus far, the rising interest rates have not had a significantly adverse effect on the economy or the stock market. The record of the Federal Reserve Board in managing interest rates in the recent past has been excellent and augurs well for the future. The continued high demand for energy, particularly in Asia, with only modest increases in supply, has resulted in historically high price levels for crude oil, coal and natural gas. Higher energy prices have probably diverted funds that would have otherwise flowed into consumer goods. As a result of higher product prices, energy stocks have constituted the stock market's best-performing sector. Your Fund is well represented in this sector, with 9.6% of the portfolio in energy shares at the fiscal year-end. The ongoing guerilla war in Iraq, with its continuing financial drain on the U.S. economy, has continued to dampen investor sentiment. Nevertheless, the stock market and the economy have performed reasonably well in the 12 months ended April 30, 2005. During the fiscal year, the value of an investment in Washington Mutual Investors Fund increased by 6.5%, assuming reinvestment of income dividends of 59.5 cents a share and the long-term capital gain distribution of 23 cents a share. These results compared with a total return of 6.3% by the unmanaged Standard & Poor's 500 Composite Index measured on the same basis. Over longer periods, your Fund's results have been as follows: Average annual total returns for periods ended April 30, 2005 1 year 5 years 10 years Lifetime* Washington Mutual +6.5% +5.1% +11.9% +12.8% S&P 500 +6.3% -2.9% +10.3% +11.3% *Since the Fund's inception on July 31, 1952. Since your Fund's October 31, 2004, semi-annual report, seven new companies have appeared in the portfolio: Amgen, Gillette, Guidant, Home Depot, Medtronic, Mylan Laboratories and Walt Disney. Five companies have been eliminated: Constellation Energy Group, Crompton, Gap, PNC Financial Services Group and Stanley Works. Gillette is now in the process of being acquired by Procter & Gamble. Washington Mutual Investors Fund has always stressed the importance of dividends (see "Seeking the Bluest of the Blue Chips" on page 6), and it is gratifying to report that 104, or 64%, of your Fund's portfolio companies increased their dividends during the past 12 months. We are always very pleased to receive questions and comments from your Fund's growing number of shareholders, now totaling over 3.7 million accounts. Cordially, James H. Lemon, Jr., Chairman of the Board Harry J. Lister, Vice Chairman of the Board < Jeffrey L. Steele, President of the Fund June 9, 2005 For current information about the Fund, visit americanfunds.com. Investment adviser's report The U.S. economy began to slow down a bit in the latter part of fiscal 2005 from its very strong pace in fiscal 2004. Commodity prices -- most particularly energy prices -- have increased substantially, with oil prices one-third higher over the past 12 months. Short-term interest rates increased from 1.0% to 3.0% since June 30, 2004. The braking effect of these two factors on the economy has become increasingly evident in 2005, mollifying concerns about inflation and holding long-term interest rates in check. In this mixed environment, the value of an investment in Washington Mutual Investors Fund, with distributions reinvested, rose 6.5% for the one-year period ended April 30, 2005. The Fund slightly surpassed the unmanaged Standard & Poor's 500 Composite Index, which rose 6.3% on a total return basis. As shown in the table on page 1, the Fund also outdistanced the S&P 500 by wider margins for the five- and 10-year periods and over its lifetime. The economic picture and outlook Gross domestic product grew at an annual rate of 3.5% during the first quarter of 2005, down from an annual rate of 3.8% in the fourth quarter of 2004. It was also below the rate of growth for all of 2004. Despite record oil prices, rising interest rates and a slowing economy, earnings of S&P 500 companies remained relatively robust, with an estimated average annual profit increase of more than 13% for the first quarter of the 2005 calendar year. That increase was indeed below the 20-percent-plus annual growth in five of the previous six quarters, but many companies showed they were able to cope with the economy's loss of momentum. The slowing of the economy after three-and-a-half years of growth should not come as a surprise. The overall pattern of the economy is typical for this stage in the business cycle, with the accelerated part of the recovery behind us. From this juncture on, it is possible that corporate earnings growth will be more modest. If that is the case, the Fund's large, globally integrated research staff should prove invaluable in finding stocks that have an opportunity to thrive in this kind of environment. The Fund's investments The Fund's five largest sectors of investment at fiscal year-end as a percentage of net assets were Financials (21.5%), Industrials (12.2%), Health care (11.2%), Energy (9.6%) and Consumer staples (9.0%). Fueled by the demand for energy and rising oil and gas prices, energy stocks helped the Fund the most during the fiscal year. Leading contributors included Exxon Mobil, the Fund's third-largest holding (+34.0%), and smaller holdings such as EOG Resources (+93.1%), Sunoco (+57.8%), Unocal (+51.4%) and ConocoPhillips (+47.1%). Aerospace and defense companies and utilities also helped. Many industry groups had mixed results. A number of our investments in financial services stocks were impacted negatively by company-specific problems. High gasoline prices also muted the results of some retailers. Wal-Mart Stores, the nation's largest retailer, said gasoline prices were crimping its customers' spending. The increasing interest in dividends by corporations and shareholders alike was a constructive development during the past year. In the first four months of 2005, 142 companies in the S&P 500 increased their dividends, up from 110 in the same period a year ago. Six companies initiated dividend payments between the start of the calendar year and April 30. More dividend-paying companies potentially mean more investment opportunities for Washington Mutual, as nearly all companies the Fund's managers can select must pay dividends. The most newsworthy dividend announcement of the past fiscal year was Microsoft's payment of a $3 per share special dividend to shareholders, for a total payout of $32 billion in December 2004. As a result of the large Microsoft dividend, the Fund paid a special four-cent dividend in December. Microsoft first began paying regular dividends in 2003. We will continue to focus our research efforts on identifying long-term investment opportunities that meet Washington Mutual's strict standards. These standards have helped us cope with a wide variety of investment markets over the long-term, and we believe they will continue to do so in the years ahead. - -- Capital Research and Management Company For current information about the Fund, visit americanfunds.com. The value of a long-term perspective How a $10,000 investment in Washington Mutual Investors Fund grew Figures shown are past results for Class A shares and are not predictive of results in future periods. Current and future results may be lower or higher than those shown. Share prices and returns will vary, so investors may lose money. For the most current information and month-end results, visit americanfunds.com. Fund figures reflect deduction of the maximum sales charge of 5.75% on a $10,000 investment./1/ Thus, the net amount invested was $9,425./2/ This chart and accompanying table show how a $10,000 investment grew between July 31, 1952, when the Fund began operations, and April 30, 2005. As you can see, that $10,000 investment in Washington Mutual, with all distributions reinvested, would have grown to $5,316,457. Over the same period, that $10,000 would have grown to $2,793,876 in the unmanaged Standard & Poor's 500 Composite Index of U.S. common stocks. According to the Consumer Price Index, it now requires $72,884 to purchase what $10,000 would have bought on July 31, 1952. 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, 1995. At that time, according to the table, the value of the investment illustrated here was $1,730,694. Since then it has gone up threefold to $5,316,457. Thus, in the same 10-year period, the value of your 1995 investment - -- regardless of its size -- has increased threefold. /1/ As outlined in the prospectus, the sales charge is reduced for accounts (and aggregated investments) of $25,000 or more and is eliminated for purchases of $1 million or more. There is no sales charge for dividends or capital gain distributions that are reinvested in additional shares. /2/ The maximum initial sales charge was 8.5% prior to July 1, 1988.

Seeking the bluest of the blue chips (Photograph: woman at computer screen) Here's why 97% of stocks don't meet Washington Mutual Investors Fund's quality standards -- and how the Fund's investment professionals select from the 3% that do. In 1830, a Massachusetts court established that people with responsibility for investing trust fund assets should do so prudently. Nearly 40 years later, the New York Court of Appeals ruled that only certain securities could be considered reasonable choices for use by fiduciaries. Over the years that followed, other states picked up on the idea and began issuing their own "Legal Lists" of approved securities. Initially, stocks seldom figured in these lists, which focused on long-term government or corporate bonds. Nearly all types of investments were crushed in the Great Depression of the 1930s, but as the dust cleared it became apparent that some stocks could be suitable for prudent investors. By the early 1940s, standards for trust fund investments had begun changing to include stocks issued by well-established, high-quality companies. "That set the stage for Washington Mutual Investors Fund," says James Lemon, chairman of the Fund's board of directors. Bernie Nees, the Fund's founder, realized that an exacting prescreening process could be useful to investors of all kinds -- not just fiduciaries. In 1952, the Fund commenced operations, adopting the Legal List criteria set up by the U.S. District Court for the District of Columbia. In the 1970s, those court-mandated rules were replaced by the more general "prudent man" rule. The Fund, however, decided to continue to embrace the conceptual investment screening process of the Legal List. Indeed, the Fund's current Investment Standards reflect only modest updates to the original screeing guidelines. The screens filter out companies whose histories have been excessively erratic, as well as new and unseasoned companies. Sometimes those situations can provide big rewards, but there's often greater risk involved. Only companies that have demonstrated their ability to produce relatively steady results over long periods of time survive the initial cut. (caption:) "...[we] focus on selecting stocks rather than timing the market." - -- Dale Harvey, portfolio counselor (Photograph of Dale Harvey) Jim Dunton, who has managed money for the Fund for 34 years, says, "The process boils things down to a manageable number of large, high-quality companies in dozens of industries. It makes it possible for us to watch the valuations and price trends every day for those that qualify, and we do." Will Robbins, the Fund's banking industry analyst, says the rigorous requirements have "led us to fish in a very attractive pond and have helped keep us out of trouble. For example, when the technology bubble burst in 2000, we felt barely a ripple, partly because most of those companies hadn't been around long enough to qualify for the Fund." The Fund seeks to be fully invested in equity securities at all times. Because shareholders are constantly putting money in the Fund and taking money out, a small portion of assets will always be in cash. However, Washington Mutual Investors Fund can't build a cash position as an investment strategy. The Fund must always be fully invested, so the investment decision makers must be constantly alert to opportunities among eligible stocks. Portfolio counselor Dale Harvey observes, "This forces us to focus on selecting stocks rather than timing the market. It also helps us keep the portfolio fresh because we must constantly reassess the stocks we feel most strongly about. The best place to put the next dollar might not be the place where we put the last dollar." Diversification is assured because, as a fundamental policy, the Fund will not invest more than 5% of assets in any one company or more than 25% in any one industry. (Inset) Stringent stock selection (as of 12/31/2004) There are about 14,000 stocks listed on U.S. exchanges. Only 344 meet Washington Mutual Investors Fund's Investment Standards. Fewer than half of those appear in the Fund's portfolio. (end of inset) (Photograph: entrance to New York Stock Exchange) Stocks must be listed on the New York Stock Exchange or meet the Exchange's financial requirements for listing. In short, the Fund focuses on stocks issued by large, highly liquid, U.S.-based companies -- which often do business all over the world. Most of their names are familiar. You see them in newspapers and magazines all the time, and you use their products every day. Given how well known they are, is it even possible their values haven't already been fully recognized in the stock market? Yes. Look at anything through a more powerful microscope and you'll always discover new details. The Fund's investment adviser, Capital Research and Management Company, is among the world's most experienced research organizations, with 140 investment professionals operating from 11 research offices around the globe. When studying big companies engaged in multiple businesses, the breadth of Capital Research's analysts means experts in several industries often compare notes about the same stock. Oil and gas industry analyst Cathy Kehr says, "I often speak with our utility analysts about the demand for electricity because this demand can influence the price of natural gas." Ray Joseph, Jr., an investment analyst who follows the insurance industry, says that one company he studies owns three TV stations and 17 radio stations. "Broadcasting accounts for about 10% of the company's earnings. So when I want to sharpen my pencil on that company, I talk with our media analyst to see how much advertising revenues might be affected by various events. Sometimes we'll even visit the company together, then share our thoughts." As two of Capital Research's investment analysts, Cathy and Ray feed information to the Fund's eight portfolio counselors, each of whom makes independent investment decisions. The investment analysts as a group also manage a portion of the Fund's assets. Portfolio counselor Jim Lovelace observes that this practice, unusual among mutual funds but widely used in the American Funds group, "gets all the analysts to work with each other collaboratively, so that they are always exchanging information and constructively critiquing each other's work." Nearly all companies must have paid dividends in at least nine of the past 10 years (four of the past five for banks and savings and loans), and earnings must have been equal to or greater than the amount paid in dividends in at least four of the past five years. When fast-growing companies are in fashion, as they were in the latter half of the 1990s, the market tends to discount the importance of dividends. Yet dividends are the closest thing to a sure return for investors. Once a dividend pattern is established, companies are reluctant to reduce it. A lower payment could send a pessimistic signal about future prospects and upset investors who were counting on the income. During periods when a company's share price is stagnant or slipping, dividends reward investors for patience. (caption:) "...we're long-term investors in quality companies, and our time horizon makes the most of our research network." - -- Ray Joseph, Jr., investment analyst (Photograph of Ray Joseph, Jr.) What's more, a dividend that's high relative to the stock price can be a sign that a company is underappreciated by the stock market. "History shows that it can be a good strategy to buy shares in out-of-favor companies paying generous dividends," says portfolio counselor Greg Johnson. "That's especially true if the companies have solid balance sheets and a long record of earning more than enough to cover the dividend payments -- exactly the sorts of companies the Fund's screening process helps to identify." Washington Mutual Investors Fund's emphasis on dividends is underscored in the Fund's investment objective: "To produce income and to provide an opportunity for growth of principal consistent with sound common stock investing." More specifically, the Fund aims to provide you with more income than you'd receive from a portfolio replicating the unmanaged Standard & Poor's 500 Composite Index. (inset) A focus on dividend-paying companies Of the approximately 160 companies reflected in the Fund's portfolio on April 30, 2005: 127 have paid uninterrupted dividends for at least 25 years 98 have paid uninterrupted dividends for at least 50 years 57 have paid uninterrupted dividends for at least 75 years 28 have paid uninterrupted dividends for at least 100 years (end of inset) The Fund's dividend standard and other quality screens, of course, limit the number of companies that may be purchased. "If we were trading-oriented, we might feel constrained by the relatively small number of stocks we can choose from for this Fund," says Ray. "But we're long-term investors in quality companies, and our time horizon makes the most of our research network. Everyone may know about Wal-Mart's next quarter. Our research effort focuses on giving us an in-depth look at prospects over the next five years." (Photograph: calculator, print out, and newspaper) Greg adds that the long experience of the Fund's investment professionals (an average of 23 years at Capital Research for the portfolio counselors, for example) is a big help. "We get to know corporate management people better than many investment firms do. We meet the next generation on their way up. You can't analyze someone in terms of integrity, people skills and ability of execution based on one visit." Experience can also give the Fund's investment decision makers an edge in discerning what's important. As Jim Dunton puts it, "When you've been watching a company for years, you have a much better idea what you're looking at -- and what it's worth." No more than 5% of the Fund's assets can be invested in companies not meeting the dividend standard, and these exceptions must meet even higher financial standards. Over the years, market trends have changed in some ways that couldn't have been anticipated when the Fund was founded. "In the late '90s, the number of companies paying dividends had shrunk and some had chosen not to pay dividends for reasons other than ability," says Dale. "So we thought about the spirit of the Fund's guidelines. Microsoft had no debt and was clearly a fabulous company. If Microsoft and companies like it weren't making the list, that suggested it was time for a small change." The Fund's board of directors agreed. Cy Ansary, a director for 22 years, says, "We're always looking at the guidelines to see if they still make sense. Usually they do. It's a testament to the original vision for the Fund. But as directors, our job is to make changes when appropriate, as we did in this case." The board updated the guidelines to allow for up to 5% of assets to be invested in extraordinary companies that clearly had the means to pay dividends. Of course, when companies like these mature, they often do begin giving a portion of earnings back to shareholders. Microsoft, added to the Fund under the rule permitting exceptions, has since begun paying dividends -- including, during the past year, the largest special cash dividend in history. The Fund cannot invest in companies that derive the majority of their revenues from alcohol or tobacco products. This prohibition wasn't part of the original standards established by the District Court. It was added in the Fund's early years. The restriction has proved popular with many investors. In fact, Washington Mutual Investors Fund is the nation's largest mutual fund with such a policy. (Caption:) "These time-tested guidelines have proved their worth." - -- Jim Dunton, portfolio counselor (Photograph of Jim Dunton) (inset) Figures shown are past results for Class A shares and are not predictive of results in future periods.

(end of inset) Of course, some companies meet the Fund's Investment Standards but don't end up in the portfolio. Concerns about management issues or major economic changes, for instance, can keep companies or entire industries out of the Fund's portfolio for a while. Dale points out that some stocks meet the standards but aren't as attractive as others. "We avoid stocks where we can't see value. Some were good investments for us years ago and some will be in the future. But at the moment, we think their prospects for the next five or 10 years are nothing special. "Washington Mutual Investors Fund is not an index fund," he continues. "It's an actively managed fund that applies a number of quality screens, resulting in a distinct group of carefully selected stocks. The difference is important, and it's been borne out in the long-term results." Since the Fund began operations in July 1952 through April 30, 2005, it has produced an average annual total return of 12.8%, versus an 11.3% gain by the unmanaged Standard & Poor's 500 Composite Index. Consider that 1.5% difference in dollar terms. A hypothetical $10,000 investment in the Fund, with dividends and capital gains reinvested, would have grown to $5,640,754. Meanwhile, the same amount invested in the S&P 500 would be worth $2,793,876. As Jim Dunton says, "These time-tested guidelines have proved their worth."

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(R) 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 redemptions None within one year of purchase without an initial sales charge) Classes B and 529-B None Declines from 5% to zero for redemptions Classes B and 529-B convert to classes A within six years of purchase and 529-A, respectively, after eight years Class C None 1% for redemptions within one year of purchase Class C converts to Class F after 10 years Class 529-C None 1% for redemptions within one year of purchase None 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 proceeds. 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 on the day the securities are being valued 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 an independent pricing service, when such prices are available. However, where the investment adviser deems it appropriate, such securities will be valued at the mean quoted bid and asked prices (or bid prices, if asked prices are not available) or at prices for securities of comparable maturity, quality and type. Securities with both fixed-income and equity characteristics, or equity securities traded principally among fixed-income dealers, are valued in the manner described above for either equity or fixed-income securities, depending on which method is deemed most appropriate by the investment adviser. Short-term securities purchased within 60 days to maturity are valued at amortized cost, which approximates market value. The value of short-term securities purchased with greater than 60 days to maturity with 60 days or less remaining to maturity is determined based on the market value on the 61st day. 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 fair valued as determined in good faith under procedures adopted by authority of the Fund's Board of Directors. Various factors may be reviewed in order to make a good faith determination of a security's fair value. These factors include, but are not limited to, the type and cost of the security; contractual or legal restrictions on resale of the security; relevant financial or business developments of the issuer; actively traded similar or related securities; conversion or exchange rights on the security; related corporate actions; significant events occurring after the close of trading in the security; and changes in overall market conditions. 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. Market discounts, premiums and original issue discounts on fixed-income securities are amortized daily over the expected life of the security. 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 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. CollegeAmerica is a registered trademark of the Virginia College Savings Plan.SM 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 short-term capital gains and losses; capital losses related to sales of certain securities within 30 days of purchase; deferred expenses; cost of investments sold; and amortization of premiums. 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, 2005, the cost of investment securities for Federal income tax purposes was $61,505,043,000. During the year ended April 30, 2005, the Fund reclassified $85,000 from undistributed net investment income to additional paid-in capital to align financial reporting with tax reporting. As of April 30, 2005, the components of distributable earnings on a tax basis were as follows (dollars in thousands): Undistributed net investment income $ 372,644 Undistributed long-term capital gains 378,119 Gross unrealized appreciation on investment securities 14,939,710 Gross unrealized depreciation on investment securities (2,211,154 ) Net unrealized appreciation on investment securities 12,728,556 During the year ended April 30, 2005, the Fund realized, on a tax basis, a net capital gain of $560,564,000.

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 encompass matters relating to general corporate governance, regulatory compliance and monitoring of the Fund's contractual service providers, including custodian operations, shareholder services and Fund share distribution functions. 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. At the beginning of the year, the agreement provided 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 0.035% on such assets in excess of $67 billion. The Board of Directors approved an amended agreement eff- ective January 15, 2005, continuing the series of rates to include an additional annual rate of 0.030% on daily net assets in excess of $77 billion. During the year ended April 30, 2005, WMC reduced business management services fees by $2,016,000. As a result, the fee shown in the accompanying financial statements of $53,358,000, which was equivalent to an annualized rate of 0.074%, was reduced to $51,342,000, or 0.072% of average daily net assets. During the fiscal year, WMC paid the Fund's investment adviser $2,147,000 for performing various fund accounting services for the Fund and for The American Funds Tax-Exempt Series I, another registered investment company for which WMC serves as business manager. Johnston, Lemon & Co. Incorporated (JLC), a wholly owned subsidiary of The Johnston-Lemon Group, Incorporated (JLG) (parent company of WMC), earned $661,000 on its retail sales of shares and distribution plans of the Fund. JLC 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. At the beginning of the year, these fees were 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. The Board of Directors approved an amended agreement effective June 17, 2004, continuing the series of rates to include an additional annual rate of 0.180% on daily net assets in excess of $71 billion. During the year ended April 30, 2005, CRMC reduced investment advisory services fees by $5,335,000. As a result, the fee shown on the accompanying financial statements of $139,427,000, which was equivalent to an annualized rate of 0.194%, was reduced to $134,092,000, or 0.187% 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 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. 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, 2005, there were no unreimbursed expenses subject to reimbursement for classes A or 529-A.

Under this agreement, these share classes compensate AFS for transfer agent services including shareholder recordkeeping, communications and transaction processing. AFS is also compensated for certain 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 year ended April 30, 2005, CRMC agreed to pay a portion of these fees for classes R-1 and R-2. For the year ended April 30, 2005, the total fees paid by CRMC were $4,000 and $630,000 for classes R-1 and R-2, respectively. Administrative services fees are presented gross of any payments made by CRMC. 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. Expenses under the agreements described above for the year ended April 30, 2005, were as follows (dollars in thousands): --------------Administraive services-------------- Commonwealth CRMC of Virginia Distribution Transfer agent administrative Transfer agent administrative Share class services services services services services Class A $141,591 $50,900 Not applicable Not applicable Not applicable Class B 27,871 2,474 Not applicable Not applicable Not applicable Class C 27,947 | $4,192 $593 Not applicable Class F 5,724 | 3,434 274 Not applicable Class 529-A 879 | 796 75 $530 Class 529-B 1,316 Included in 197 55 132 Class 529-C 1,922 administrative 288 65 192 Class 529-E 147 services 44 4 30 Class 529-F 41 | 25 2 16 Class R-1 247 | 37 17 Not applicable Class R-2 3,733 | 747 1,960 Not applicable Class R-3 6,937 | 2,081 251 Not applicable Class R-4 1,335 | 801 16 Not applicable Class R-5 Not applicable | 517 10 Not applicable Total $219,690 $53,374 $13,159 $3,322 $900 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 compensation of $803,000, shown on the accompanying financial statements, includes $730,000 in current fees (either paid in cash or deferred) and a net increase of $73,000 in the value of the deferred amounts. Affiliated officers and Directors -- All officers of the Fund and all of its Directors who are affiliated with WMC receive no compensation directly from the Fund in such capacities. 4.

(the "Fund") at April 30, 2005, and the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the 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 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 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 at April 30, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion. PricewaterhouseCoopers LLP Los Angeles, California June 3, 2005 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.

Please see the Financial Highlights table on page 26 for details. <FN> <F1> From March 15, 2000, when Class B shares were first sold. <F2> From March 15, 2001, when Class C and Class F shares were first sold. <F3> These shares are sold without any initial or contingent deferred sales charge. <F4> From February 15, 2002, when Class 529-A and Class 529-C shares were first sold. <F5> From February 19, 2002, when Class 529-B shares were first sold. <F6> From March 1, 2002, when Class 529-E shares were first sold. <F7> From September 16, 2002, when Class 529-F shares were first sold. </FN> There are several ways to invest in Washington Mutual Investors Fund. Class A shares are subject to a 5.75% maximum up-front sales charge that declines for accounts (and aggregated investments) of $25,000 or more and is eliminated for purchases of $1 million 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 0.77 percentage points 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 0.85 percentage points 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 0.08 percentage points) 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. Expense example (unaudited) As a shareholder of the Fund, you incur two types of costs: (1) transaction costs such as initial sales charges on purchase payments and contingent deferred sales charges on redemptions (loads); and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund so you can compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (November 1, 2004 through April 30, 2005). Actual expenses: The first line of each share class in the table on the next page provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading entitled "Expenses paid during period" to estimate the expenses you paid on your account during this period. There are some account fees that are charged to certain types of accounts, such as Individual Retirement Accounts and CollegeAmerica accounts (generally, a $10 fee is charged to set up the account and an additional $10 fee is charged to the account annually) that would increase the amount of expenses paid on your account. In addition, retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F and Class 529-F shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would also be lower by the amount of these fees. Hypothetical example for comparison purposes: The second line of each share class in the table on the next page provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio for the share class and an assumed rate of return of 5.00% per year before expenses, which is not the actual return of the 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 the Fund and other funds. To do so, compare this 5.00% hypothetical example with the 5.00% hypothetical examples that appear in the shareholder reports of the other funds. There are some account fees that are charged to certain shareholders, such as Individual Retirement Accounts and CollegeAmerica accounts (generally, a $10 fee is charged to set up the account and an additional $10 fee is charged to the account annually) that would increase the amount of expenses paid on your account. In addition, retirement plan participants may be subject to certain fees charged by the plan sponsor, and Class F and Class 529-F shareholders may be subject to fees charged by financial intermediaries, typically ranging from 0.75% to 1.50% of assets annually depending on services offered. You can estimate the impact of these fees by adding the amount of the fees to the total estimated expenses you paid on your account during the period as calculated above. In addition, your ending account value would also be lower by the amount of these fees. 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). Therefore, the second line of each share class in 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.

This report is for the information of shareholders of Washington Mutual Investors Fund, but it may also be used as sales literature when preceded or accompanied by the current prospectus, which gives details about charges, expenses, investment objectives and operating policies of the Fund.

What makes American Funds different? For more than 70 years, we have followed a consistent philosophy that we firmly believe is in our investors' best interests. The range of opportunities offered by our family of just 29 carefully conceived, broadly diversified funds has attracted over 30 million shareholder accounts. Our unique combination of strengths includes these five factors: - - A long-term, value-oriented approach Rather than follow fads, we pursue a consistent strategy, focusing on each investment's long-term potential. - - An unparalleled global research effort American Funds draws on one of the industry's most globally integrated research networks. - - The multiple portfolio counselor system Every American Fund is divided among a number of portfolio counselors. Each takes responsibility for a portion independently, within each fund's objectives; in most cases, research analysts manage a portion as well. Over time this method has contributed to a consistency of results and continuity of management. - - Experienced investment professionals The recent market decline was not the first for most of the portfolio counselors who serve the American Funds. More than half of them were in the investment business before the sharp market decline of 1987. - - A commitment to low operating expenses American Funds' operating expenses are among the lowest in the mutual fund industry. Our portfolio turnover rates are low as well, keeping transaction costs and tax consequences contained. Investors should carefully consider the investment objectives, risks, charges and expenses of the American Funds and CollegeAmerica. This and other important information is contained in the Fund's prospectus and the CollegeAmerica program description, which can be obtained from your financial adviser and should be read carefully before investing. You may also call American Funds Service Company (AFS) at 800/421-0180 or visit the American Funds website at americanfunds.com. "American Funds Proxy Voting Guidelines" -- which describes how we vote proxies relating to portfolio securities -- is available free of charge on the U.S. Securities and Exchange Commission (SEC) website at www.sec.gov, on the American Funds website or upon request by calling AFS. The Fund's proxy voting record for the 12 months ended June 30, 2004, is also available on the SEC and American Funds websites.

The Registrant undertakes to provide to any person without charge, upon request, a copy of the Code of Ethics. Such request can be made to American Funds Service Company at 800/421-0180 or to the Secretary of the Registrant, 1101 Vermont Avenue, NW, Suite 600, Washington, DC 20005. ITEM 3 - Audit Committee Financial Expert The Registrant's Board has determined that Charles A. Bowsher, a member of the Registrant's Audit Committee, is an "audit committee financial expert" and "independent," as such terms are defined in this Item. This designation will not increase the designee's duties, obligations or liability as compared to his duties, obligations and liability as a member of the Audit Committee and of the Board; nor will it reduce the responsibility of the other Audit Committee members. There may be other individuals who, through education or experience, would qualify as "audit committee financial experts" if the Board had designated them as such. Most importantly, the Board believes each member of the Audit Committee contributes significantly to the effective oversight of the Registrant's financial statements and condition. ITEM 4 - Principal Accountant Fees and Services Registrant: a) Audit Fees: 2004 $98,000 2005 $85,000 b) Audit- Related Fees: 2004 none 2005 none c) Tax Fees: 2004 $6,000 2005 $7,000 The tax fees consist of professional services relating to the preparation of the registrant's tax returns. d) All Other Fees: 2004 none 2005 none ITEM 4 - Principal Accountant Fees and Services (continued) Adviser and affiliates (includes only fees for non-audit services billed to the adviser and affiliates for engagements that relate directly to the operations and financial reporting of the registrant and were subject to the pre-approval policies described below): a) Audit- Related Fees: 2004 none 2005 none b) Tax Fees: 2004 none 2005 none c) All Other Fees: 2004 none 2005 none The registrant's Audit Committee will pre-approve all audit and permissible non-audit services that the Committee considers compatible with maintaining the auditors' independence. The pre-approval requirement will extend to all non-audit services provided to the registrant, the business manager, the investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser or business manager that provides ongoing services to the registrant, if the engagement relates directly to the operations and financial reporting of the registrant. The Committee will not delegate its responsibility to pre-approve these services to the business manager or investment adviser. The Committee may delegate to one or more Committee members the authority to review and pre-approve audit and permissible non-audit services. Actions taken under any such delegation will be reported to the full Committee at its next meeting. The pre-approval requirement is waived with respect to non-audit services if certain conditions are met. The pre-approval requirement was not waived for any of the services listed above under paragraphs b, c and d. Aggregate non-audit fees paid to the registrant's auditors, including fees for all services billed to the adviser and affiliates were $6,000 for fiscal year 2004 and $0 for fiscal year 2005. The non-audit services represented by these amounts were brought to the attention of the Committee and considered to be compatible with maintaining the auditors' independence. ITEM 5 - Audit Committee of Listed Registrants Not applicable. ITEM 6 - Schedule of Investments The full schedule of investments for the Fund is included as part of the report to shareholders filed under Item 1 of this Form. ITEM 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company. ITEM 8 - Portfolio Managers of Equity Securities by Closed End Management Investment Companies Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company. ITEM 9 - Purchases of Equity Securities by Closed-End Management Investment Company and Affiliated Purchasers Not applicable to this Registrant, insofar as the Registrant is not a closed-end management investment company. ITEM 10 - Submission of Matters to a Vote of Security Holders There have been no material changes to the procedures by which shareholders may recommend nominees to the registrant's Board of Directors since the registrant last submitted a proxy statement to its shareholders. The procedures are as follows. The registrant has a Governance Committee comprised solely of persons who are not considered "interested persons" of the registrant within the meaning of the Investment Company Act of 1940. The committee periodically reviews such issues as the Board's composition, responsibilities, committees, compensation and other relevant issues, and recommends any appropriate changes to the full Board of Directors. While the committee normally is able to identify from its own resources an ample number of qualified candidates, it will consider shareholder suggestions of persons to be considered as nominees to fill future vacancies on the Board. Such suggestions must be sent in writing to the Governance Committee of the registrant, c/o the registrant's Secretary, and should be accompanied by complete biographical and occupational data on the prospective nominee, along with a written consent of the prospective nominee for consideration of his or her name by the Governance Committee. ITEM 11 - Controls and Procedures (a) The Registrant's Principal Executive Officer and Principal Financial Officer have concluded, based on their evaluation of the Registrant's disclosure controls and procedures (as such term is defined in Rule 30a-3 under the Investment Company Act of 1940), that such controls and procedures are adequate and reasonably designed to achieve the purposes described in paragraph (c) of such rule. (b) There were no changes in the Registrant's internal controls over financial reporting (as defined in Rule 30a-3(d) under the Investment Company Act of 1940) that occurred during the Registrant's last fiscal half-year (the Registrant's second fiscal half-year in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the Registrant's internal control over financial reporting. ITEM 12 - Exhibits (a) The Code of Ethics that is the subject of the disclosure required by Item 2 is attached as an exhibit hereto. (b) The certifications required by Rule 30a-2 of the Investment Company Act of 1940, as amended, and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002 are attached as exhibits hereto.
