Semi-annual report for the six months ended October 31, 2005

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 organization ranks among the
nation's three largest mutual fund families. 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 in this report are past results for Class A shares (unless
otherwise indicated) and are not predictive of results in future periods. 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.
Current and future results may be lower or higher than those shown. For the most
current information and month-end results, visit americanfunds.com. 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.

Here are the average annual total returns on a $1,000 investment with all
distributions reinvested for periods ended September 30, 2005 (the most recent
calendar quarter):

The Fund's investment adviser and business manager each waived 5% of their
manage-ment fees from September 1, 2004 through March 31, 2005, and increased
the waivers to 10% on April 1, 2005. Fund results shown reflect the waivers,
without which they would have been lower. Please see the Financial Highlights
table on page 22 for details.

Despite rising interest rates, higher energy prices and Gulf Coast hurricanes in
late summer, the nation's economy -- as represented by its gross domestic
product -- expanded at an annual rate of 4.3% in the third quarter ended
September 30, 2005. This continuing strength reinforced the Federal Reserve
Board's resolve to continue increasing the federal funds rate (now up to 4.0%).
The Federal Reserve Board remains concerned that higher energy costs may soon be
increasingly reflected in higher prices of both goods and services. Thus far,
however, general price increases have been moderate and long-term interest rates
have been relatively stable.

For the past six months, Washington Mutual Investors Fund's total return, with
dividends reinvested, was 2.8%, compared with the unmanaged Standard & Poor's
500 Composite Index's total return of 5.3%. This period was one in which smaller
and more speculative companies showed greater relative returns than large,
mature companies. Over longer periods, your Fund showed the following results:

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

Washington Mutual's concentration of holdings remained almost identical to that
of a year ago, with financials at almost 22% of net assets. The excellent income
stream from the financial sector was an important factor facilitating the
increase in Washington Mutual's quarterly dividend to 15 cents per share in
June. During the six-month period, 46 (or 29%) of the Fund's holdings increased
their dividends.

During the six-month period, six new equity securities have appeared in the
Fund's portfolio: Baker Hughes, Gap, Harley-Davidson Motor, Johnson Controls,
McKesson and R.R. Donnelley & Sons. Meanwhile, 10 companies have been
eliminated: ALLTEL, Burlington Northern Santa Fe, CenturyTel, Comerica, Dow
Jones, Gillette, Honeywell International, IKON Office Solutions, Mylan
Laboratories and Unocal.

We wish to inform you that T. Eugene Smith will be retiring this month after 18
years of dedicated service on the Fund's Board of Directors. We are deeply
appreciative of his advice, support and leadership. The Board of Directors has
elected Barbara Hackman Franklin as an independent Director of the Fund. Ms.
Franklin is president and CEO of Barbara Franklin Enterprises, an international
business consulting firm. She served as the 29th U.S. Secretary of Commerce in
the administration of President George H.W. Bush. Ms. Franklin serves on the
board of several public companies and has been recognized as "Director of the
Year" by The National Association of Corporate Directors (2000) and Board Alert
(2003). She is currently a member of the Public Company Accounting Oversight
Board Advisory Council, a Trustee of the Financial Accounting Foundation and
chairman of the Economic Club of New York. In addition, the Fund's Board has
elected R. Clark Wadlow to serve on the Fund's Advisory Board. Mr. Wadlow is an
attorney with extensive experience in the communications industry.

As always, we are pleased to hear your comments and questions.

Cordially,

1. 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) 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
                    sales     Contingent deferred sales

College Savings Plan.(SM)

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,
     including short-term securities purchased with more than 60 days left to
     maturity, 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 originally purchased with maturities greater than 60 days is
     determined based on an amortized value to par when they reach 60 days or
     less remaining to maturity. 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 for financial reporting purposes. The
Fund may also designate a portion of the amount paid to redeeming shareholders
as a distribution for tax purposes. As of October 31, 2005, the cost of
investment securities for Federal income tax purposes was $61,268,430,000.

During the six months ended October 31, 2005, the Fund reclassified $42,000,000
from undistributed net realized gains to capital paid in on shares of capital
stock to align financial reporting with tax reporting.

As of October 31, 2005, the components of distributable earnings on a tax basis
were as follows (dollars in thousands):

  Undistributed net investment income                          $         401,974
  Undistributed long-term capital gains                                  758,895
  Gross unrealized appreciation on investment securities              16,258,231
  Gross unrealized depreciation on investment securities             (2,664,943)
  Net unrealized appreciation on investment securities                13,593,288

During the six months ended October 31, 2005, the Fund realized, on a tax basis,
a net capital gain of $422,776,000.

The tax character of distributions paid to shareholders was as follows (dollars
in thousands):

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 0.030% on such assets in excess of $77 billion. WMC
is currently waiving 10% of business management services fees. During the six
months ended October 31, 2005, total business management services fees waived by
WMC were $2,775,000. As a result, the fee shown on the accompanying financial
statements of $27,745,000, which was equivalent to an annualized rate of 0.072%,
was reduced to $24,970,000, or 0.065% of average daily net assets. During the
six months ended October 31, 2005, WMC paid the Fund's investment adviser
$1,165,000 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 $270,000 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. 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 0.177% on such assets in excess
of $89 billion. CRMC is currently waiving 10% of investment advisory services
fees. During the six months ended October 31, 2005, total investment advisory
services fees waived by CRMC were $7,472,000. As a result, the fee shown on the
accompanying financial statements of $74,720,000, which was equivalent to an
annualized rate of 0.193%, was reduced to $67,248,000, or 0.174% 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
     shareclasses, 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 and service existing accounts. The
     plans provide for payments, based on an annualized percentage of average
     daily net assets, ranging from 0.25% to 1.00% as noted on the following
     page. In some cases, the Board of Directors has limited the amounts that
     may be paid to less than the maximum allowed by the plans. 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. The remaining amounts available to be paid under each plan are
     paid to selling dealers to compensate them for their selling activities.

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.  These  classes  reimburse  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, 2005,  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 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 share  classes  other than classes A and B. Each  relevant  share class pays
CRMC  annual fees of up to 0.15%  (0.10% for Class R-5) based on its  respective
average  daily net assets.  Each relevant  share 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.  CRMC has agreed to pay
AFS on the Fund's behalf for a portion of the transfer  agent  services fees for
some of the retirement plan share classes.  For the six months ended October 31,
2005,  the total  administrative  services  fees paid by CRMC  were  $2,000  and
$345,000 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  on  the  accompanying  financial
statements, the Commonwealth of Virginia is not considered a related party.

 Expenses under the agreements described on the previous page for the six months
 ended October 31, 2005, 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 of $472,000, shown on the accompanying financial statements,
includes $427,000 in current fees (either paid in cash or deferred) and a net
increase of $45,000 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.

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,
2005 through October 31, 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 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 on
the previous page. 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.

Approval of renewal of Investment Advisory Agreement

On June 16, 2005, the Fund's Board of Directors (the "Board"), including the
Independent Directors, approved the renewal of the Fund's Investment Advisory
Agreement (the "Agreement") with Capital Research and Management Company
("CRMC") for an additional one-year term through August 31, 2006. The Board
approved renewal of the Agreement following the recommendation of the Fund's
Governance Committee (the "Committee"), which is comprised of all of the Fund's
Independent Directors. The information, material factors and conclusions that
formed the basis for the Committee's recommendation and the Board's subsequent
approval are described below.

1.   Information received

Materials reviewed -- During the course of each year, the Independent Directors
receive a wide variety of materials relating to the services provided by CRMC,
including reports on the investment results of the Fund; portfolio composition;
portfolio trading practices; shareholder services; and other information
relating to the nature, extent and quality of services provided by CRMC to the
Fund. In addition, supplementary information requested and reviewed by the
Committee included extensive materials regarding the Fund's investment results,
advisory fee and expense comparisons (including comparisons to advisory fees
charged by an affiliate of CRMC to institutional clients), financial and
profitability information regarding CRMC, descriptions of various functions such
as compliance monitoring and portfolio trading practices, and information about
the personnel providing investment management and other services to the Fund.

Review process -- The Committee received assistance and advice regarding legal
and industry standards from independent counsel to the Fund and its Directors.
The Directors also reviewed independent reports providing analysis and
comparative data related to the Fund's fees and operations. The Committee
discussed the renewal of the Agreement with a senior representative of CRMC, as
well as Fund officers, and in a private session with independent legal counsel.
In deciding to recommend the renewal of the Agreement, the Committee did not
identify any single or particular piece of information that, in isolation, was a
controlling factor. This summary describes the more important, but not all, of
the factors considered by the Board and the Committee.

2. Nature, extent and quality of services

CRMC, its personnel and its resources -- The Board and the Committee considered
the depth and quality of CRMC's investment management process, including its
research capabilities; the experience, capability and integrity of its senior
management and other personnel; the low turnover rates of its key personnel; the
overall financial strength and stability of its organization; and the ability of
its organizational structure to address the recent growth in complex-wide assets
under management. The Board and the Committee also considered that CRMC made
available to its investment professionals a variety of resources and systems
relating to investment management, compliance, trading, results and portfolio
accounting. They recognized CRMC's commitment to investing in information
technology supporting investment management and compliance. They recognized
CRMC's continuing need to attract and retain qualified personnel and to maintain
and enhance its resources and systems.

Other services -- The Board and the Committee considered CRMC's (or its
affiliates') policies, procedures and systems to ensure compliance with
applicable laws and regulations and its commitment to these programs; its
efforts to keep the Directors informed; and its attention to matters that may
involve conflicts of interest with the Fund. The Board and the Committee also
considered the nature, extent, quality and cost of distribution and shareholder
services provided by CRMC to the Fund under various agreements with the Fund.
Ultimately, the Board and the Committee concluded that the nature, extent and
quality of the services provided by CRMC have benefited and will continue to
benefit the Fund and its shareholders.

3. Investment results

The Board and the Committee examined both the short-term and long-term
investment results of the Fund in light of its primary objective of providing
income and growth of principal through investments in quality common stocks. In
particular, the Board and the Committee considered analytical data developed by
Lipper that compared the performance of the Fund relative to the Lipper
Large-Cap Value Funds Index, the Lipper Growth & Income Funds Index and the
Standard & Poor's 500 Composite Index. It was noted that although the Fund
underperformed the comparisons in certain one-year periods, its return was
superior over the 10-year period. The Board and the Committee ultimately
concluded that CRMC's record in managing the Fund indicates that its continued
advisory services will benefit the Fund and its shareholders.

4. Advisory fees and total expenses

The Board and the Committee reviewed the advisory fees and total expenses of the
Fund (as a percentage of average net assets) and compared such amounts with the
average fee and expense levels of other similar mutual funds. In particular, the
Board and the Committee reviewed data that compared the median advisory fees of
other large-cap value funds, with the advisory fees of the Fund, noting that the
Fund's advisory fees were lower. The Board and Committee also reviewed data
comparing expense information on the largest 25 actively-managed funds,
regardless of investment classification or objective, and noted that the Fund
ranked 9 out of 25 for lowest total expenses and 6 out of 25 when excluding Rule
12b-1 service fees. They also noted the voluntary fee waiver that CRMC put into
effect complex-wide during the past year. Based on the information presented by
CRMC, members of the Board and the Committee then determined, in their business
judgment, that the relatively low level of the fees charged by CRMC will benefit
the Fund and its shareholders.

5. Adviser costs, level of profits and economies of scale

The Board and the Committee reviewed information regarding CRMC's costs of
providing services to the American Funds as a whole, as well as the resulting
level of profits to CRMC, noting that those results were comparable to the
reported results of several large publicly held investment management companies.
The Committee noted that it had also received information during the past year
regarding the structure and manner in which CRMC's investment professionals were
compensated and CRMC's view of the relationship of such compensation to the
attraction and retention of quality personnel. The Board and the Committee
considered CRMC's willingness to invest in technology, infrastructure and staff
to reinforce and offer new services to accommodate changing regulatory
requirements. They further considered the Fund's advisory fee structure in
relation to the Fund's total assets. The fee structure includes a series of
breakpoints with an additional breakpoint incorporated into the fee structure at
a total Fund asset level of $89 billion. The Board and the Committee concluded
that the Fund's cost structure was reasonable and that CRMC was sharing
economies of scale with the Fund and its shareholders.

6. Ancillary benefits

The Board and the Committee considered a variety of other benefits received by
CRMC and its affiliates as a result of CRMC's relationship with the Fund and
other American Funds, including fees for administrative services provided to
certain share classes; fees paid to CRMC's affiliated transfer agent; sales
charges and distribution fees received and retained by the Fund's principal
underwriter, an affiliate of CRMC; and possible ancillary benefits to CRMC's
institutional management affiliate. The Board and the Committee reviewed CRMC's
portfolio trading practices, noting that, while CRMC receives the benefit of
research provided by broker-dealers executing portfolio transactions on behalf
of the American Funds, it does not obtain third-party research or other services
in return for allocating brokerage to such broker-dealers.

7. Conclusions

Based on their review, including their consideration of each of the factors
referred to above, the Board and the Committee concluded that the nature, extent
and quality of the services rendered to the Fund by CRMC continued to be
excellent and favored renewal of the Agreement. The Board and the Committee
concluded that the Agreement continued to be fair and reasonable to the Fund and
its shareholders, that the Fund's shareholders received reasonable value in
return for the advisory fees and other amounts paid to CRMC by the Fund, and
that the renewal of the Agreement was in the best interests of the Fund and its
shareholders.

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 0.76 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 annualized expenses 0.82 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 0.05 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.

Investors should carefully consider the investment objectives, risks, charges
and expenses of the American Funds and CollegeAmerica. This and other important

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

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.

     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.
