Washington Mutual Investors Fund

Semi-annual report for the six months ended October 31, 2004

Washington Mutual Investors Fund(SM) seeks to provide income and growth of
principal through investments in quality common stocks.

This Fund is one of the 29 American Funds, the nation's third-largest mutual
fund family. For more than seven decades, Capital Research and Management
Company(SM), the American Funds adviser, has invested with a long-term focus
based on thorough research and attention to risk.

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. 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. For the most current information and month-end results, visit
americanfunds.com. Fund results shown, unless otherwise indicated, are at net
asset value. If a sales charge (maximum 5.75%) had been deducted, the results
would have been lower.

Here are the average annual total returns on a $1,000 investment with all
distributions reinvested for periods ended September 30, 2004 (the most recent
calendar quarter):

Class A shares
                                                   1 year    5 years  10 years
Reflecting 5.75% maximum sales charge
   Average annual total return                       --      +3.30%    +12.09%
   Cumulative total return                         +9.74%    +17.61%  +213.14%

The Fund's investment adviser and business manager are waiving 5% of their
management fees for the period September 1, 2004 through August 31, 2005. Over
that one-year period, the fee waivers will amount to approximately a two basis
point reduction in fund expenses. Without the waivers the returns of the Fund
shown in this report would have been slightly lower.

Results for other share classes can be found on page 24. Please see the inside
back cover for important information about other share classes.

Fellow shareholders:

The U.S. economy continued to recover at a moderate pace during the six months
ended October 31, 2004. Washington Mutual Investors Fund participated in the
economic recovery with a modest increase of 3.0% a share, with dividends
reinvested. The Fund's result matched the 3.0% total return of the unmanaged
Standard & Poor's 500 Composite Index, a broad measure of the U.S. stock market.

For the past 12 months, your Fund's total return, with distributions reinvested,
was 10.9%, outpacing the S&P 500's total return of 9.4%. Over longer periods,
your Fund has produced even stronger relative returns, which are as follows:

Average annual total returns
                                      1 year    5 years  10 years Lifetime/1/
Washington Mutual                     +10.9%     +3.4%    +12.6%    +12.8%
S&P 500                                +9.4%     -2.2%    +11.0%    +11.3%


/1/ Since the Fund's inception on July 31, 1952.


Although the Fund's overall return was modest for the six months ended October
31, some industries showed strong gains during the period. Bolstered by sharply
rising oil and gas prices, energy stocks -- which made up 9.4% of the Fund's
assets at the end of the period -- made the greatest contribution. The Fund
benefited from its substantial holdings of ChevronTexaco and Exxon Mobil.
Defense stocks gained, reflecting increased government spending for the global
war on terrorism. Pharmaceutical stocks generally lagged the market during this
period because of adverse publicity involving specific drugs, which were
withdrawn from the market.

The Federal Reserve Board has signaled its intention to increase the federal
funds rate at a measured pace to what it terms a neutral level. Since June 30,
the Fed has raised the rate four times to its current level of 2.0%. In
contrast, long-term interest rates have generally declined; the rate on 10-year
government notes is around the four percent level. Equity prices are usually not
greatly affected until the final stages of a series of expected interest rate
increases.

Dividends have always been important to your Fund, so it is a pleasure to report
that in the six months under review, 45 companies in Washington Mutual's
portfolio -- 28% of total holdings -- declared dividend increases. As a result
of this trend, Fund Directors were able to increase the quarterly dividend on
the Fund's Class A shares paid on September 20, 2004, to 14 cents a share from
13.5 cents. The Fund's December dividend income will be favorably affected by
the receipt of a special dividend of $3.00 a share on its holdings of 27.9
million shares of Microsoft. As a result of the Microsoft special dividend, the
Fund also expects to pay a special dividend in December, in addition to its
regular quarterly dividend of 14 cents a share.

As of October 31, your Fund's total assets were $71.0 billion, the highest level
ever reported in the Fund's 52-year history. We believe that our investment
management approach -- the multiple portfolio counselor system -- is an
effective way to manage the Fund's sizable holdings. Under this system, the
Fund's assets are divided into portions. Each of the Fund's eight portfolio
counselors manages a portion independently; a ninth portion is managed by the
Fund's research analysts, who are specialists in specific industries. All
investment decisions are made within the standards established by Washington
Mutual's objective, policies and restrictions.

We cordially welcome our new shareholders and express appreciation for the
loyalty of our shareholder family, which now consists of more than 3.6 million
accounts.

We will be pleased to hear your comments and questions at any time.

Cordially,

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 at prices for securities of comparable
maturity, quality and type. 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.

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 October 31, 2004, the cost of
investment securities for federal income tax purposes was $59,083,358,000.

As of October 31, 2004, the components of distributable earnings on a tax basis
were as follows (dollars in thousands):

Undistributed net investment income                               $   296,565
Accumulated short-term capital losses                                 (96,819)
Undistributed long-term capital gains                                 444,113
Gross unrealized appreciation on investment securities             14,228,234
Gross unrealized depreciation on investment securities             (2,492,854)
Net unrealized appreciation on investment securities               11,735,380

During the six months ended October 31, 2004, the Fund realized, on a tax basis,
a net capital loss of $29,839,000.

The tax character of distributions paid to shareholders was as follows (dollars

3. 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.
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 0.035% of such assets in excess of $67 billion.
During the six months ended October 31, 2004, WMC reduced business management
services fees by $442,000. As a result, the fee shown in the accompanying
financial statements of $26,366,000, which was equivalent to an annualized rate
of 0.076%, was reduced to $25,924,000, or 0.075% of average daily net assets.
Johnston, Lemon & Co. Incorporated (JLC), a wholly owned subsidiary of The
Johnston-Lemon Group, Incorporated (JLG), earned $323,000 on its retail sales of
shares and distribution plans 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. 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 six
months ended October 31, 2004, CRMC reduced investment advisory services fees by
$1,148,000. As a result, the fee shown on the accompanying financial statements
of $67,533,000, which was equivalent to an annualized rate of 0.195%, was
reduced to $66,385,000, or 0.192% 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 October 31, 2004,
     there were no unreimbursed expenses subject to reimbursement for classes A
     or 529-A.

     Share class                Currently approved limits            Plan limits
     Class A                              0.25%                         0.25%

     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
     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 six months ended October 31, 2004, CRMC agreed to pay
     a portion of these fees for classes R-1 and R-2. 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 six months ended
     October 31, 2004, were as follows (dollars in thousands):

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 in the accompanying financial statements includes $343,000 in

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 (May 1,
2004 through October 31, 2004).

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 0.50% to 3.00% of assets
annually depending on services offered. You may use the information in the table
on the next page to estimate the impact of these fees by adding the amount of
the fees to the number in the first line for your share class under the heading
entitled "Expenses paid during period", and subtracting the amount of the fees
from the number in the first line under the heading entitled "Ending account
value".

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 0.50% to 3.00%
of assets annually depending on services offered. You may use the information in
the table below to estimate the impact of these fees by adding the amount of the
fees to the number in the second line for your share class under the heading
entitled "Expenses paid during period", and subtracting the amount of the fees
from the number in the second line under the heading entitled "Ending account
value".

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.

The Fund's investment adviser and business manager are waiving 5% of their
management fees for the period September 1, 2004 through August 31, 2005. Over
that one-year period, the fee waivers will amount to approximately a two basis
point reduction in fund expenses. Without the waivers the returns of the Fund
shown in this report would have been slightly lower.

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. Annualized
expenses for Class B shares were 0.78 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(C)) of up to 5% that declines over time. Class C
shares were subject to annualized expenses 0.86 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 annualized
expenses (by 0.09 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.

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 -  Purchase  of Equity  Securities  by Closed End  Management  Investment
Company and Affiliated Procedures

Not applicable to this Registrant, insofar as the Registrant is not a closed-end

ITEM 9 - 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 10 - Controls and Procedures

(a)  The officers providing the certifications in this report in accordance with
     rule 30a-2 under the Investment Company Act of 1940 have concluded, based
     on their evaluation of the Registrant's disclosure controls and procedures
     (as such term is defined in such rule), 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.
