Risk/Return summary

The fund seeks to make your investment grow by investing primarily in common
stocks of companies that appear to offer superior opportunities for growth of
capital.

The fund is designed for investors seeking capital appreciation through stocks.
 Investors in the fund should have a long-term perspective and, for example, be
able to tolerate potentially sharp, short-term declines in value.

Your investment in the fund is subject to risks, including the possibility that
the value of the fund's portfolio holdings may fluctuate in response to events
specific to the companies or markets in which the fund invests, as well as
economic, political or social events in the United States or abroad.

Your investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency, entity or person.

YOU MAY LOSE MONEY BY INVESTING IN THE FUND. THE LIKELIHOOD OF LOSS MAY BE
GREATER IF YOU INVEST FOR A SHORTER PERIOD OF TIME.

HISTORICAL INVESTMENT RESULTS

The bar chart below shows how the fund's investment results have varied from
year to year, and the Investment Results table on page 3 shows how the fund's
average annual total returns for various periods compare with a broad measure of
market performance. This information provides some indication of the risks of
investing in the fund. All fund results reflect the reinvestment of dividends
and capital gain distributions, if any. Unless otherwise noted, fund results
reflect any fee waivers and/or expense reimbursements in effect during the
period presented. Past results are not predictive of future results.

Unlike the bar chart on the previous page, the Investment Results table below
reflects, as required by Securities and Exchange Commission rules, the fund's
investment results with the following maximum initial sales charge imposed:

 . Class A share results reflect the maximum initial sales charge of 5.75%. This
   charge is reduced for purchases of $25,000 or more and eliminated for
   purchases of $1 million or more.

 . Class R shares are sold without any initial sales charge.

Results would be higher if calculated without a sales charge.

Unlike the Investment Results table below, the Additional Investment Results
table on page 8 reflects the fund's results calculated without a sales charge.

investment adviser, affiliates of the adviser and unaffiliated third parties for
providing recordkeeping and other administrative services to retirement plans
invested in the fund in lieu of the transfer agent providing such services. The
amount paid for subtransfer agent/recordkeeping services will vary depending on
the share class selected and the entity receiving the payments. The table below

EXAMPLES

The examples below are intended to help you compare the cost of investing in the
fund with the cost of investing in other mutual funds. The examples assume that
you invest $10,000 in the fund for the time periods indicated, that your
investment has a 5% return each year, that all dividends and capital gain
distributions are reinvested, and that the fund's operating expenses remain the
same as shown above. The examples do not reflect the impact of any fee waivers
or expense reimbursements.

Although your actual costs may be higher or lower, based on these assumptions,
your cumulative estimated expenses would be:

Investment objective, strategies and risks

The fund's investment objective is to provide you with growth of capital. The
fund invests primarily in common stocks.

The prices of securities held by the fund may decline in response to certain
events, including those directly involving the companies whose securities are
owned by the fund; conditions affecting the general economy; overall market
changes; local, regional or global political, social or economic instability;
and currency, interest rate and commodity price fluctuations. The
growth-oriented, equity-type securities generally purchased by the fund may
involve large price swings and potential for loss.

The fund may also hold cash or money market instruments. The percentage of the
fund invested in such holdings varies and depends on various factors, including
market conditions and purchases and redemptions of fund shares. A larger
percentage of such holdings could moderate the fund's investment results in a
period of rising market prices.

A larger percentage of cash or money market instruments could reduce the
magnitude of the fund's loss in a period of falling market prices and provide
liquidity to make additional investments or to meet redemptions.

The fund relies on the professional judgment of its investment adviser to make
decisions about the fund's portfolio investments. The basic investment
philosophy of the investment adviser is to seek to invest in attractively valued
companies that, in its opinion, represent good, long-term investment
opportunities. The investment adviser believes that an important way to
accomplish this is through fundamental analysis, which may include meeting with
company executives and employees, suppliers, customers and competitors.
Securities may be sold when the investment adviser believes that they no longer
represent relatively attractive investment opportunities.

OTHER IMPORTANT INVESTMENT PRACTICES

In addition to the principal investment strategies described above, the fund has
other investment practices that are described in this prospectus and in the
statement of additional information.

The fund may invest up to 15% of its assets in securities of issuers domiciled
outside the United States and Canada and not included in Standard & Poor's 500
Composite Index. Investments outside the United States may be subject to certain
risks. For example, changes in relationships among global currencies may trigger
declines in the value of the fund's holdings. Investing in securities issued by
entities based outside the United States may also be affected by currency
controls, different accounting and legal standards, expropriation, tax policies,
greater market volatility and various administrative difficulties.

The fund may invest up to 10% of its assets in lower quality nonconvertible debt
securities (rated Ba1 or below by Moody's Investors Service and BB+ or below by
Standard & Poor's Corporation or unrated but determined by the fund's investment
adviser to be of equivalent quality). The values of debt securities may be
affected by changing interest rates and by changes in effective maturities and
credit ratings of these securities. For example, the values of debt securities
generally decline when interest rates rise and increase when interest rates
fall. Debt securities are also subject to credit risk, which is the possibility
that the credit strength of an issuer will weaken and/or an issuer of a debt
security will fail to make timely payments of principal or interest and the
security will go into default. Lower quality or longer maturity debt securities
generally have higher rates of interest and may be subject to greater price
fluctuations than higher quality or shorter maturity debt securities.

The fund's investment adviser attempts to reduce these risks through
diversification of the portfolio and ongoing credit analysis, as well as by
monitoring economic and legislative developments, but there can be no assurance
that it will be successful at doing so.

2   Lifetime results for the index(es) shown are measured from the date Capital
    Research and Management Company became the fund's investment adviser. The funds
    or securities that compose each index may vary over time.
3   Lipper Capital Appreciation Funds Index is an equally weighted index of funds
    that aim for maximum capital appreciation. The results of the underlying funds
    in the index include the reinvestment of dividends and capital gain
    distributions, as well as brokerage commissions paid by the funds for portfolio
    transactions, but do not reflect the effect of sales charges or taxes.
4   Lipper Growth Funds Index is an equally weighted index of growth funds. These
    funds normally invest in companies with long-term earnings that are expected to
    grow significantly faster than the earnings of the stocks represented in the
    major unmanaged indexes. The results of the underlying funds in the index
    include the reinvestment of dividends and capital gain distributions, as well
    as brokerage commissions paid by the funds for portfolio transactions, but do
    not reflect the effect of sales charges or taxes.
5   Lipper Multi-Cap Growth Funds Index is an equally weighted index of funds that
    invest in a variety of market capitalization ranges without concentrating 75%
    of their equity assets in any one market capitalization range over an extended
    period of time. Multi-cap growth funds typically have an above-average
    price-to-earnings ratio, price-to-book ratio and three-year sales-per-share
    growth value, compared to the S&P SuperComposite 1500 Index (a broad-based
    index representing the large-cap, mid-cap and small-cap segments of the U.S.
    equity market). The results of the underlying funds in the index include the
    reinvestment of dividends and capital gain distributions, as well as brokerage
    commissions paid by the funds for portfolio transactions, but do not reflect
    the effect of sales charges or taxes.
6   Lipper Multi-Cap Core Funds Index is an equally weighted index of funds that
    invest in a variety of market capitalization ranges without concentrating 75%
    of their equity assets in any one market capitalization range over an extended
    period of time. These funds typically have an average price-to-earnings ratio,
    price-to-book ratio and three-year sales-per-share growth value, compared to
    the S&P SuperComposite 1500 Index (a broad-based index representing the
    large-cap, mid-cap and small-cap segments of the U.S. equity market). The
    results of the underlying funds in the index include the reinvestment of
    dividends and capital gain distributions, as well as brokerage commissions paid
    by the funds for portfolio transactions, but do not reflect the effect of sales
    charges or taxes.

Management and organization

INVESTMENT ADVISER

Capital Research and Management Company, an experienced investment management
organization founded in 1931, serves as investment adviser to the fund and other
funds, including the American Funds. Capital Research and Management Company is
a wholly owned subsidiary of The Capital Group Companies, Inc. and is located at
333 South Hope Street, Los Angeles, California 90071, and 6455 Irvine Center
Drive, Irvine, California 92618. Capital Research and Management Company manages
the investment portfolio and business affairs of the fund. The total management
fee paid by the fund, as a percentage of average net assets, for the previous
fiscal year appears in the Annual Fund Operating Expenses table under "Fees and
expenses of the fund." A discussion regarding the basis for the approval of the
fund's investment advisory and service agreement by the fund's board of
directors is contained in the fund's annual report to shareholders for the
fiscal year ended August 31, 2008.

Capital Research and Management Company manages equity assets through two
investment divisions, Capital World Investors and Capital Research Global
Investors, and manages fixed-income assets through its Fixed Income division.
Capital World Investors and Capital Research Global Investors make investment
decisions on an independent basis.

Rather than remain as investment divisions, Capital World Investors and Capital
Research Global Investors may be incorporated into wholly owned subsidiaries of
Capital Research and Management Company. In that event, Capital Research and
Management Company would continue to be the investment adviser, and day-to-day
investment management of equity assets would continue to be carried out through
one or both of these subsidiaries. Capital Research and Management Company and
the funds it advises have applied to the Securities and Exchange Commission for
an exemptive order that would give Capital Research and Management Company the
authority to use, upon approval of the funds' boards, its management
subsidiaries and affiliates to provide day-to-day investment management services
to the funds, including making changes to the management subsidiaries and
affiliates providing such services. Approval by the funds' shareholders would be
required before any authority granted under an exemptive order could be
exercised. There is no assurance that Capital Research and Management Company
will incorporate its investment divisions or seek a shareholder vote to exercise
any authority, if granted, under an exemptive order.

EXECUTION OF PORTFOLIO TRANSACTIONS

The investment adviser places orders with broker-dealers for the fund's
portfolio transactions. In selecting broker-dealers, the investment adviser
strives to obtain "best execution" (the most favorable total price reasonably
attainable under the circumstances) for the fund's portfolio transactions,
taking into account a variety of factors. Subject to best execution, the
investment adviser may consider investment research and/or brokerage services
provided to the adviser in placing orders for the fund's portfolio transactions.
The investment adviser may place orders for the fund's portfolio transactions
with broker-dealers who have sold shares of funds managed by the investment
adviser or its affiliated companies; however, it does not give consideration to
whether a broker-dealer has sold shares of the funds managed by the investment
adviser or its affiliated companies when placing any such orders for the fund's
portfolio transactions. A more detailed description of the investment adviser's
policies is included in the fund's statement of additional information.

PORTFOLIO HOLDINGS

Portfolio holdings information for the fund is available on the American Funds
website at americanfunds.com. To reach this information, access the fund's
detailed information page on the website. A list of the fund's top 10 equity
holdings, updated as of each month-end, is generally posted to this page within
14 days after the end of the applicable month. A link to the fund's complete
list of publicly disclosed portfolio holdings, updated as of each calendar
quarter-end, is generally posted to this page within 45 days after the end of
the applicable quarter. Both lists remain available on the website until new
information for the next month or quarter is posted. Portfolio holdings
information for the fund is also contained in reports filed with the Securities
and Exchange Commission.

A description of the fund's policies and procedures regarding disclosure of
information about its portfolio holdings is available in the statement of
additional information.

MULTIPLE PORTFOLIO COUNSELOR SYSTEM

Capital Research and Management Company uses a system of multiple portfolio
counselors in managing mutual fund assets. Under this approach, the portfolio of
a fund is divided into segments managed by individual counselors who decide how
their respective segments will be invested. In addition, Capital Research and
Management Company's investment analysts may make investment decisions with
respect to a portion of a fund's portfolio. Investment decisions are subject to
a fund's objective(s), policies and restrictions and the oversight of the
appropriate investment-related committees of Capital Research and Management
Company and its investment divisions.

FREQUENT TRADING OF FUND SHARES

The fund and American Funds Distributors reserve the right to reject any
purchase order for any reason. The fund is not designed to serve as a vehicle
for frequent trading. Frequent trading of fund shares may lead to increased
costs to the fund and less efficient management of the fund's portfolio,
potentially resulting in dilution of the value of the shares held by long-term
shareholders. Accordingly, purchases, including those that are part of exchange
activity that the fund or American Funds Distributors has determined could
involve actual or potential harm to the fund, may be rejected.

The fund, through its transfer agent, American Funds Service Company, maintains
surveillance procedures that are designed to detect frequent trading in fund
shares. Under these procedures, various analytics are used to evaluate factors
that may be indicative of frequent trading. For example, transactions in fund
shares that exceed certain monetary thresholds may be scrutinized. American
Funds Service Company also may review transactions that occur close in time to
other transactions in the same account or in multiple accounts under common
ownership or influence. Trading activity that is identified through these
procedures or as a result of any other information available to the fund will be
evaluated to determine whether such activity might constitute frequent trading.
These procedures may be modified from time to time as appropriate to improve the
detection of frequent trading, to facilitate monitoring for frequent trading in
particular retirement plans or other accounts, and to comply with applicable
laws.

In addition to the fund's broad ability to restrict potentially harmful trading
as described above, the fund's board of directors has adopted a "purchase
blocking policy" under which any shareholder redeeming shares having a value of
$5,000 or more from the fund will be precluded from investing in the fund for 30
calendar days after the redemption transaction. This policy also applies to
redemptions and purchases that are part of exchange transactions. Under the
fund's purchase blocking policy, certain purchases will not be prevented and
certain redemptions will not trigger a purchase block, such as systematic
redemptions and purchases, where the entity maintaining the shareholder account
is able to identify the transaction as a systematic redemption or purchase;
purchases and redemptions of shares having a value of less than $5,000;
transactions in Class 529 shares; purchases and redemptions resulting from
reallocations by American Funds Target Date Retirement Series; retirement plan
contributions, loans and distributions (including hardship withdrawals)
identified as such on the retirement plan recordkeeper's system; and purchase
transactions involving transfers of assets, rollovers, Roth IRA conversions and
IRA recharacterizations, where the entity maintaining the shareholder account is
able to identify the transaction as one of these types of transactions.

The fund reserves the right to waive the purchase blocking policy with respect
to specific shareholder accounts in those instances where American Funds Service
Company determines that its surveillance procedures are adequate to detect
frequent trading in fund shares.

American Funds Service Company will work with certain intermediaries (such as
investment dealers holding shareholder accounts in street name, retirement plan
recordkeepers, insurance company separate accounts and bank trust companies) to
apply their own procedures, provided that American Funds Service Company
believes the intermediary's procedures are reasonably designed to enforce the
frequent trading policies of the fund. You should refer to disclosures provided
by the intermediaries with which you have an account to determine the specific
trading restrictions that apply to you.

If American Funds Service Company identifies any activity that may constitute
frequent trading, it reserves the right to contact the intermediary and request
that the intermediary either provide information regarding an account owner's
transactions or restrict the account owner's trading. If American Funds Service
Company is not satisfied that the intermediary has taken appropriate action,
American Funds Service Company may terminate the intermediary's ability to
transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will
be prevented.

NOTWITHSTANDING THE FUND'S SURVEILLANCE PROCEDURES AND PURCHASE BLOCKING POLICY,
ALL TRANSACTIONS IN FUND SHARES REMAIN SUBJECT TO THE FUND'S AND AMERICAN FUNDS
DISTRIBUTORS' RIGHT TO RESTRICT POTENTIALLY ABUSIVE TRADING GENERALLY (INCLUDING
THE TYPES OF TRANSACTIONS DESCRIBED ABOVE THAT WILL NOT BE PREVENTED OR TRIGGER
A BLOCK UNDER THE PURCHASE BLOCKING POLICY). SEE THE STATEMENT OF ADDITIONAL
INFORMATION FOR MORE INFORMATION ABOUT HOW AMERICAN FUNDS SERVICE COMPANY MAY
ADDRESS OTHER POTENTIALLY ABUSIVE TRADING ACTIVITY IN THE AMERICAN FUNDS.

SALES

Please contact your plan administrator or recordkeeper in order to sell shares
from your retirement plan.

RIGHT OF REINVESTMENT

If you notify American Funds Service Company, you may reinvest proceeds from a
redemption, dividend payment or capital gain distribution without a sales charge
in the same fund or other American Funds, provided that the reinvestment occurs
within 90 days after the date of the redemption or distribution and is made into
the same account from which you redeemed the shares or received the
distribution. If the account has been closed, you may reinvest without a sales
charge if the new receiving account has the same registration as the closed
account. Proceeds will be reinvested in the same share class from which the
original redemption or distribution was made. Redemption proceeds of Class A
shares representing direct purchases in American Funds money market funds that
are reinvested in non-money market American Funds will be subject to a sales
charge. Proceeds will be reinvested at the next calculated net asset value after
your request is received and accepted by American Funds Service Company. For
purposes of this "right of reinvestment policy," automatic transactions
(including, for example, automatic purchases, withdrawals and payroll
deductions) and ongoing retirement plan

contributions are not eligible for investment without a sales charge. See the
statement of additional information for further information. You may not
reinvest proceeds in the American Funds as described in this paragraph if such
proceeds are subject to a purchase block as described under "Frequent trading of
fund shares" in this prospectus. This paragraph does not apply to certain
rollover investments as described under "Rollovers from retirement plans to
IRAs" in this prospectus.

VALUING SHARES

The net asset value of each share class of the fund is the value of a single
share. The fund calculates the net asset value each day the New York Stock
Exchange is open for trading as of approximately 4 p.m. New York time, the
normal close of regular trading. Assets are valued primarily on the basis of
market quotations. However, the fund has adopted procedures for making "fair
value" determinations if market quotations are not readily available or are not
considered reliable. For example, if events occur between the close of markets
outside the United States and the close of regular trading on the New York Stock
Exchange that, in the opinion of the investment adviser, materially affect the
value of any of the fund's securities that principally trade in those
international markets, those securities will be valued in accordance with fair
value procedures. Use of these procedures is intended to result in more
appropriate net asset values. In addition, such use will reduce, if not
eliminate, potential arbitrage opportunities otherwise available to short-term
investors.

Because the fund may hold securities that are primarily listed on foreign
exchanges that trade on weekends or days when the fund does not price its
shares, the value of securities held in the fund may change on days when you
will not be able to purchase or redeem fund shares.

Your shares will be purchased at the net asset value (plus any applicable sales
charge in the case of Class A shares) or sold at the net asset value next
determined after American Funds Service Company receives and accepts your
request.

MOVING BETWEEN SHARE CLASSES AND ACCOUNTS

Please see the statement of additional information for details and limitations
on moving investments in certain share classes to different share classes and on
moving investments held in certain accounts to different accounts.

Sales charges

CLASS A SHARES

The initial sales charge you pay each time you buy Class A shares differs
depending upon the amount you invest and may be reduced or eliminated for larger
purchases as indicated below. The "offering price," the price you pay to buy
shares, includes any applicable sales charge, which will be deducted directly
from your investment. Shares acquired through reinvestment of dividends or
capital gain distributions are not subject to an initial sales charge.


                                       SALES CHARGE AS A

The sales charge, expressed as a percentage of the offering price or the net
amount invested, may be higher or lower than the percentages described in the
table above due to rounding. This is because the dollar amount of the sales
charge is determined by subtracting the net asset value of the shares purchased
from the offering price, which is calculated to two decimal places using
standard rounding criteria. The impact of rounding will vary with the size of
the investment and the net asset value of the shares.

CLASS A PURCHASES NOT SUBJECT TO SALES CHARGES

The following investments are not subject to any initial or contingent deferred
sales charge if American Funds Service Company is properly notified of the
nature of the investment:

. investments made by accounts that are part of certain qualified fee-based
  programs and that purchased Class A shares before the discontinuation of your
  investment dealer's load-waived Class A share program with the American Funds;
  and

. certain rollover investments from retirement plans to IRAs (see "Rollovers
  from retirement plans to IRAs" in this prospectus for more information).

                                        The Growth Fund of America / Prospectus
<PAGE>

The distributor may pay dealers up to 1% on investments made in Class A shares
with no initial sales charge. The fund may reimburse the distributor for these
payments through its plans of distribution (see "Plans of distribution" in this
prospectus).

Certain other investors may qualify to purchase shares without a sales charge,
such as employees of investment dealers and registered investment advisers
authorized to sell American Funds, and employees of The Capital Group Companies.
Please see the statement of additional information for more information.

 EMPLOYER-SPONSORED RETIREMENT PLANS

 Employer-sponsored retirement plans that are eligible to purchase Class R
 shares may instead purchase Class A shares and pay the applicable Class A sales
 charge, provided their recordkeepers can properly apply a sales charge on plan
 investments. These plans are not eligible to make initial purchases of $1
 million or more in Class A shares and thereby invest in Class A shares without
 a sales charge, nor are they eligible to establish a statement of intention
 that qualifies them to purchase Class A shares without a sales charge. More
 information about statements of intention can be found under "Sales charge
 reductions" in this prospectus. Plans investing in Class A shares with a sales
 charge may purchase additional Class A shares in accordance with the sales
 charge table in this prospectus.

 Employer-sponsored retirement plans that invested in Class A shares without any
 sales charge on or before March 31, 2004, and that continue to meet the
 eligibility requirements in effect as of that date for purchasing Class A
 shares at net asset value, may continue to purchase Class A shares without any
 initial or contingent deferred sales charge.

 A 403(b) plan may not invest in Class A or C shares, unless such plan was
 invested in Class A or C shares prior to January 1, 2009.

CLASS R SHARES

Class R shares are sold without any initial or contingent deferred sales charge.
The distributor will pay dealers annually an asset-based compensation of up to
1.00% for sales of Class R-1 shares, up to .75% for Class R-2 shares, up to .50%
for Class R-3 shares and up to .25% for Class R-4 shares. No dealer compensation
is paid from fund assets on sales of Class R-5 or R-6 shares. The fund may
reimburse the distributor for these payments through its plans of distribution
(see "Plans of distribution" in this prospectus).

Sales charge reductions

TO RECEIVE A REDUCTION IN YOUR CLASS A INITIAL SALES CHARGE, YOU MUST LET YOUR
FINANCIAL ADVISER OR AMERICAN FUNDS SERVICE COMPANY KNOW AT THE TIME YOU
PURCHASE SHARES THAT YOU QUALIFY FOR SUCH A REDUCTION. IF YOU DO NOT LET YOUR
ADVISER OR AMERICAN FUNDS SERVICE COMPANY KNOW THAT YOU ARE ELIGIBLE FOR A
REDUCTION, YOU MAY NOT RECEIVE A SALES CHARGE DISCOUNT TO WHICH YOU ARE
OTHERWISE ENTITLED. In order to determine your eligibility to receive a sales
charge discount, it may be necessary for you to provide your adviser or American
Funds Service Company with information and records (including account
statements) of all relevant accounts invested in the American Funds.

IN ADDITION TO THE INFORMATION IN THIS PROSPECTUS, YOU MAY OBTAIN MORE
INFORMATION ABOUT SHARE CLASSES, SALES CHARGES AND SALES CHARGE REDUCTIONS
THROUGH A LINK ON THE HOME PAGE OF THE AMERICAN FUNDS WEBSITE AT
AMERICANFUNDS.COM, FROM THE STATEMENT OF ADDITIONAL INFORMATION OR FROM YOUR
FINANCIAL ADVISER.

REDUCING YOUR CLASS A INITIAL SALES CHARGE

Consistent with the policies described in this prospectus, two or more
retirement plans of an employer or employer's affiliates may combine all of
their American Funds investments to reduce their Class A sales charge. Certain
investments in the American Funds Target Date Retirement Series may also be
combined for this purpose. Please see the American Funds Target Date Retirement
Series prospectus for further information. However, for this purpose,
investments representing direct purchases of American Funds money market funds
are excluded. Following are different ways that you may qualify for a reduced
Class A sales charge:

 CONCURRENT PURCHASES

 Simultaneous purchases of any class of shares of two or more American Funds
 (excluding American Funds money market funds) may be combined to qualify for a
 reduced Class A sales charge.

 RIGHTS OF ACCUMULATION

 You may take into account your accumulated holdings in all share classes of the
 American Funds (excluding American Funds money market funds) to determine the
 initial sales charge you pay on each purchase of Class A shares. Subject to
 your investment dealer's or recordkeeper's capabilities, your accumulated
 holdings will be calculated as the higher of (a) the current value of your
 existing holdings or (b) the amount you invested (including reinvested
 dividends and capital gains, but excluding capital appreciation) less any
 withdrawals. Please see the statement of additional information for further
 details. You should retain any records necessary to substantiate the historical
 amounts you have invested.

<PAGE>

 STATEMENT OF INTENTION

 You may reduce your Class A sales charge by establishing a statement of
 intention. A statement of intention allows you to combine all purchases of all
 share classes of the American Funds (excluding American Funds money market
 funds) you intend to make over a 13-month period to determine the applicable
 sales charge; however, purchases made under a right of reinvestment,
 appreciation of your holdings, and reinvested dividends and capital gains do
 not count as purchases made during the statement period. The market value of
 your existing holdings eligible to be aggregated as of the day immediately
 before the start of the statement period may be credited toward satisfying the
 statement. A portion of your account may be held in escrow to cover additional
 Class A sales charges that may be due if your total purchases over the
 statement period do not qualify you for the applicable sales charge reduction.
 Employer-sponsored retirement plans may be restricted from establishing
 statements of intention. See "Sales charges" in this prospectus for more
 information.

RIGHT OF REINVESTMENT

Please see the "Sales" section of "Purchase, exchange and sale of shares" in
this prospectus for information on how to reinvest proceeds from a redemption,
dividend payment or capital gain distribution without a sales charge.

Rollovers from retirement plans to IRAs

Assets from retirement plans may be invested in Class A, C or F shares
through an IRA rollover, subject to the other provisions of this prospectus and
the prospectus for nonretirement plan shareholders. More information on Class C
and F shares can be found in the fund's prospectus for nonretirement plan
shareholders. Rollovers invested in Class A shares from retirement plans will be
subject to applicable sales charges. The following rollovers to Class A shares
will be made without a sales charge:

. rollovers to IRAs from 403(b) plans with Capital Bank and Trust Company as
  custodian; and

. rollovers to IRAs that are attributable to American Funds investments, if they
  meet the following requirements:

  -- the assets being rolled over were invested in American Funds at the time of
     distribution; and

  -- the rolled over assets are contributed to an American Funds IRA with Capital
     Bank and Trust Company as custodian.

IRA rollover assets that roll over without a sales charge as described above
will not be subject to a contingent deferred sales charge and investment dealers
will be compensated solely with an annual service fee that begins to accrue
immediately. IRA rollover assets invested in Class A shares that are not
attributable to American Funds investments, as well as future contributions to
the IRA, will be subject to sales charges and the terms and conditions generally
applicable to Class A share investments as described in this prospectus and the
statement of additional information.

Plans of distribution

The fund has plans of distribution or "12b-1 plans" for certain share classes,
under which it may finance activities primarily intended to sell shares,
provided the categories of expenses are approved in advance by the fund's board
of directors. The plans provide for payments, based on annualized percentages of
average daily net assets, of up to .25% for Class A shares, up to 1.00% for
Class R-1 and R-2 shares, up to .75% for Class R-3 shares and up to .50% for
Class R-4 shares. For all share classes indicated above, up to .25% of these
expenses may be used to pay service fees to qualified dealers for providing
certain shareholder services. The amount remaining for each share class may be
used for distribution expenses.

The 12b-1 fees paid by the fund, as a percentage of average net assets for the
previous fiscal year, are indicated in the Annual Fund Operating Expenses table
under "Fees and expenses of the fund" in this prospectus. Since these fees are
paid out of the fund's assets or income on an ongoing basis, over time they will
increase the cost and reduce the return of your investment.

Other compensation to dealers

American Funds Distributors, at its expense, currently provides additional
compensation to investment dealers. These payments may be made, at the
discretion of American Funds Distributors, to the top 100 dealers (or their
affiliates) that have sold shares of the American Funds. The level of payments
made to a qualifying firm in any given year will vary and in no case would
exceed the sum of (a) .10% of the previous year's American Funds sales by that
dealer and (b) .02% of American Funds assets attributable to that dealer. For
calendar year 2008, aggregate payments made by American Funds Distributors to
dealers were less than .02% of the average assets of the American Funds.
Aggregate payments may also change from year to year. A number of factors will
be considered in determining payments, including the qualifying dealer's sales,
assets and redemption rates, and the quality of the dealer's relationship with
American Funds Distributors. American Funds Distributors makes these payments to
help defray the costs incurred by qualifying dealers in connection with efforts
to educate financial advisers about the American Funds so that they can make
recommendations and provide services that are suitable and meet shareholder
needs. American Funds Distributors will, on an annual basis, determine the
advisability of continuing these payments. American Funds Distributors may also
pay expenses associated with meetings conducted by dealers outside the top 100
firms to facilitate educating financial advisers and shareholders about the
American Funds. If investment advisers, distributors or other affiliates of
mutual funds pay additional compensation or other incentives in differing
amounts, dealer firms and their advisers may have financial incentives for
recommending a particular mutual fund over other mutual funds. You should
consult with your financial adviser and review carefully any disclosure by your
financial adviser's firm as to compensation received.

Distributions and taxes

DIVIDENDS AND DISTRIBUTIONS

The fund intends to distribute dividends to shareholders, usually in December.

Capital gains, if any, are usually distributed in December. When a dividend or
capital gain is distributed, the net asset value per share is reduced by the
amount of the payment.

All dividends and capital gain distributions paid to retirement plan
shareholders will be automatically reinvested.

TAXES ON DIVIDENDS AND DISTRIBUTIONS

Dividends and capital gains distributed by the fund to tax-deferred retirement
plan accounts are not taxable currently.

TAXES ON TRANSACTIONS

Exchanges within a tax-deferred retirement plan account will not result in a
capital gain or loss for federal or state income tax purposes. With limited
exceptions, distributions from a retirement plan account are taxable as ordinary
income.

PLEASE SEE YOUR TAX ADVISER FOR MORE INFORMATION.

Financial highlights

The Financial Highlights table is intended to help you understand the fund's
results for the past five fiscal years. Certain information reflects financial
results for a single share of a particular class. A similar table will be shown
for Class R-6 shares beginning with the fund's fiscal year ending after the date
the share class is first offered. The total returns in the table represent the
rate that an investor would have earned or lost on an investment in the fund
(assuming reinvestment of all dividends and capital gain distributions). Where
indicated, figures in the table reflect the impact, if any, of certain
reimbursements/waivers from Capital Research and Management Company. For more
information about these reimbursements/waivers, see the footnotes to the Annual
Fund Operating Expenses table under "Fees and expenses of the fund" in this
prospectus and the fund's annual report. The information in the Financial
Highlights table has been audited by Deloitte & Touche LLP, whose report, along
with the fund's financial statements, is included in the statement of additional
information, which is available upon request.

Risk/Return summary

The fund seeks to make your investment grow by investing primarily in common
stocks of companies that appear to offer superior opportunities for growth of
capital.

The fund is designed for investors seeking capital appreciation through stocks.
 Investors in the fund should have a long-term perspective and, for example, be
able to tolerate potentially sharp, short-term declines in value.

Your investment in the fund is subject to risks, including the possibility that
the value of the fund's portfolio holdings may fluctuate in response to events
specific to the companies or markets in which the fund invests, as well as
economic, political or social events in the United States or abroad.

Your investment in the fund is not a bank deposit and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency, entity or person.

YOU MAY LOSE MONEY BY INVESTING IN THE FUND. THE LIKELIHOOD OF LOSS MAY BE
GREATER IF YOU INVEST FOR A SHORTER PERIOD OF TIME.

Unlike the bar chart on the previous page, the Investment Results table below
reflects, as required by Securities and Exchange Commission rules, the fund's
investment results with the following maximum initial sales charge imposed:

 . Class A share results reflect the maximum initial sales charge of 5.75%. This
   charge is reduced for purchases of $25,000 or more and eliminated for
   purchases of $1 million or more.

 . Class R shares are sold without any initial sales charge.

Results would be higher if calculated without a sales charge.

Unlike the Investment Results table below, the Additional Investment Results
table on page 8 reflects the fund's results calculated without a sales charge.

EXAMPLES

The examples below are intended to help you compare the cost of investing in the
fund with the cost of investing in other mutual funds. The examples assume that
you invest $10,000 in the fund for the time periods indicated, that your
investment has a 5% return each year, that all dividends and capital gain
distributions are reinvested, and that the fund's operating expenses remain the
same as shown above. The examples do not reflect the impact of any fee waivers
or expense reimbursements.

Although your actual costs may be higher or lower, based on these assumptions,
your cumulative estimated expenses would be:

Investment objective, strategies and risks

The fund's investment objective is to provide you with growth of capital. The
fund invests primarily in common stocks.

The prices of securities held by the fund may decline in response to certain
events, including those directly involving the companies whose securities are
owned by the fund; conditions affecting the general economy; overall market
changes; local, regional or global political, social or economic instability;
and currency, interest rate and commodity price fluctuations. The
growth-oriented, equity-type securities generally purchased by the fund may
involve large price swings and potential for loss.

The fund may also hold cash or money market instruments. The percentage of the
fund invested in such holdings varies and depends on various factors, including
market conditions and purchases and redemptions of fund shares. A larger
percentage of such holdings could moderate the fund's investment results in a
period of rising market prices.

A larger percentage of cash or money market instruments could reduce the
magnitude of the fund's loss in a period of falling market prices and provide
liquidity to make additional investments or to meet redemptions.

The fund relies on the professional judgment of its investment adviser to make
decisions about the fund's portfolio investments. The basic investment
philosophy of the investment adviser is to seek to invest in attractively valued
companies that, in its opinion, represent good, long-term investment
opportunities. The investment adviser believes that an important way to
accomplish this is through fundamental analysis, which may include meeting with
company executives and employees, suppliers, customers and competitors.
Securities may be sold when the investment adviser believes that they no longer
represent relatively attractive investment opportunities.

OTHER IMPORTANT INVESTMENT PRACTICES

In addition to the principal investment strategies described above, the fund has
other investment practices that are described in this prospectus and in the
statement of additional information.

The fund may invest up to 15% of its assets in securities of issuers domiciled
outside the United States and Canada and not included in Standard & Poor's 500
Composite Index. Investments outside the United States may be subject to certain
risks. For example, changes in relationships among global currencies may trigger
declines in the value of the fund's holdings. Investing in securities issued by
entities based outside the United States may also be affected by currency
controls, different accounting and legal standards, expropriation, tax policies,
greater market volatility and various administrative difficulties.

The fund may invest up to 10% of its assets in lower quality nonconvertible debt
securities (rated Ba1 or below by Moody's Investors Service and BB+ or below by
Standard & Poor's Corporation or unrated but determined by the fund's investment
adviser to be of equivalent quality). The values of debt securities may be
affected by changing interest rates and by changes in effective maturities and
credit ratings of these securities. For example, the values of debt securities
generally decline when interest rates rise and increase when interest rates
fall. Debt securities are also subject to credit risk, which is the possibility
that the credit strength of an issuer will weaken and/or an issuer of a debt
security will fail to make timely payments of principal or interest and the
security will go into default. Lower quality or longer maturity debt securities
generally have higher rates of interest and may be subject to greater price
fluctuations than higher quality or shorter maturity debt securities.

The fund's investment adviser attempts to reduce these risks through
diversification of the portfolio and ongoing credit analysis, as well as by
monitoring economic and legislative developments, but there can be no assurance
that it will be successful at doing so.

    or securities that compose each index may vary over time.
3   Lipper Capital Appreciation Funds Index is an equally weighted index of funds
    that aim for maximum capital appreciation. The results of the underlying funds
    in the index include the reinvestment of dividends and capital gain
    distributions, as well as brokerage commissions paid by the funds for portfolio
    transactions, but do not reflect the effect of sales charges or taxes.
4   Lipper Growth Funds Index is an equally weighted index of growth funds. These
    funds normally invest in companies with long-term earnings that are expected to
    grow significantly faster than the earnings of the stocks represented in the
    major unmanaged indexes. The results of the underlying funds in the index
    include the reinvestment of dividends and capital gain distributions, as well
    as brokerage commissions paid by the funds for portfolio transactions, but do
    not reflect the effect of sales charges or taxes.
5   Lipper Multi-Cap Growth Funds Index is an equally weighted index of funds that
    invest in a variety of market capitalization ranges without concentrating 75%
    of their equity assets in any one market capitalization range over an extended
    period of time. Multi-cap growth funds typically have an above-average
    price-to-earnings ratio, price-to-book ratio and three-year sales-per-share
    growth value, compared to the S&P SuperComposite 1500 Index (a broad-based
    index representing the large-cap, mid-cap and small-cap segments of the U.S.
    equity market). The results of the underlying funds in the index include the
    reinvestment of dividends and capital gain distributions, as well as brokerage
    commissions paid by the funds for portfolio transactions, but do not reflect
    the effect of sales charges or taxes.
6   Lipper Multi-Cap Core Funds Index is an equally weighted index of funds that
    invest in a variety of market capitalization ranges without concentrating 75%
    of their equity assets in any one market capitalization range over an extended
    period of time. These funds typically have an average price-to-earnings ratio,
    price-to-book ratio and three-year sales-per-share growth value, compared to
    the S&P SuperComposite 1500 Index (a broad-based index representing the
    large-cap, mid-cap and small-cap segments of the U.S. equity market). The
    results of the underlying funds in the index include the reinvestment of
    dividends and capital gain distributions, as well as brokerage commissions paid
    by the funds for portfolio transactions, but do not reflect the effect of sales
    charges or taxes.

expenses of the fund." A discussion regarding the basis for the approval of the
fund's investment advisory and service agreement by the fund's board of
directors is contained in the fund's annual report to shareholders for the
fiscal year ended August 31, 2008.

Capital Research and Management Company manages equity assets through two
investment divisions, Capital World Investors and Capital Research Global
Investors, and manages fixed-income assets through its Fixed Income division.
Capital World Investors and Capital Research Global Investors make investment
decisions on an independent basis.

Rather than remain as investment divisions, Capital World Investors and Capital
Research Global Investors may be incorporated into wholly owned subsidiaries of
Capital Research and Management Company. In that event, Capital Research and
Management Company would continue to be the investment adviser, and day-to-day
investment management of equity assets would continue to be carried out through
one or both of these subsidiaries. Capital Research and Management Company and
the funds it advises have applied to the Securities and Exchange Commission for
an exemptive order that would give Capital Research and Management Company the
authority to use, upon approval of the funds' boards, its management
subsidiaries and affiliates to provide day-to-day investment management services
to the funds, including making changes to the management subsidiaries and
affiliates providing such services. Approval by the funds' shareholders would be
required before any authority granted under an exemptive order could be
exercised. There is no assurance that Capital Research and Management Company
will incorporate its investment divisions or seek a shareholder vote to exercise
any authority, if granted, under an exemptive order.

EXECUTION OF PORTFOLIO TRANSACTIONS

The investment adviser places orders with broker-dealers for the fund's
portfolio transactions. In selecting broker-dealers, the investment adviser
strives to obtain "best execution" (the most favorable total price reasonably
attainable under the circumstances) for the fund's portfolio transactions,
taking into account a variety of factors. Subject to best execution, the
investment adviser may consider investment research and/or brokerage services
provided to the adviser in placing orders for the fund's portfolio transactions.
The investment adviser may place orders for the fund's portfolio transactions
with broker-dealers who have sold shares of funds managed by the investment
adviser or its affiliated companies; however, it does not give consideration to
whether a broker-dealer has sold shares of the funds managed by the investment
adviser or its affiliated companies when placing any such orders for the fund's
portfolio transactions. A more detailed description of the investment adviser's
policies is included in the fund's statement of additional information.

PORTFOLIO HOLDINGS

Portfolio holdings information for the fund is available on the American Funds
website at americanfunds.com. To reach this information, access the fund's
detailed information page on the website. A list of the fund's top 10 equity
holdings, updated as of each month-end, is generally posted to this page within
14 days after the end of the applicable month. A link to the fund's complete
list of publicly disclosed portfolio holdings, updated as of each calendar
quarter-end, is generally posted to this page within 45 days after the end of
the applicable quarter. Both lists remain available on the website until new
information for the next month or quarter is posted. Portfolio holdings
information for the fund is also contained in reports filed with the Securities
and Exchange Commission.

A description of the fund's policies and procedures regarding disclosure of
information about its portfolio holdings is available in the statement of
additional information.

MULTIPLE PORTFOLIO COUNSELOR SYSTEM

Capital Research and Management Company uses a system of multiple portfolio
counselors in managing mutual fund assets. Under this approach, the portfolio of
a fund is divided into segments managed by individual counselors who decide how
their respective segments will be invested. In addition, Capital Research and
Management Company's investment analysts may make investment decisions with
respect to a portion of a fund's portfolio. Investment decisions are subject to
a fund's objective(s), policies and restrictions and the oversight of the
appropriate investment-related committees of Capital Research and Management
Company and its investment divisions.

FREQUENT TRADING OF FUND SHARES

The fund and American Funds Distributors reserve the right to reject any
purchase order for any reason. The fund is not designed to serve as a vehicle
for frequent trading. Frequent trading of fund shares may lead to increased
costs to the fund and less efficient management of the fund's portfolio,
potentially resulting in dilution of the value of the shares held by long-term
shareholders. Accordingly, purchases, including those that are part of exchange
activity that the fund or American Funds Distributors has determined could
involve actual or potential harm to the fund, may be rejected.

The fund, through its transfer agent, American Funds Service Company, maintains
surveillance procedures that are designed to detect frequent trading in fund
shares. Under these procedures, various analytics are used to evaluate factors
that may be indicative of frequent trading. For example, transactions in fund
shares that exceed certain monetary thresholds may be scrutinized. American
Funds Service Company also may review transactions that occur close in time to
other transactions in the same account or in multiple accounts under common
ownership or influence. Trading activity that is identified through these
procedures or as a result of any other information available to the fund will be
evaluated to determine whether such activity might constitute frequent trading.
These procedures may be modified from time to time as appropriate to improve the
detection of frequent trading, to facilitate monitoring for frequent trading in
particular retirement plans or other accounts, and to comply with applicable
laws.

In addition to the fund's broad ability to restrict potentially harmful trading
as described above, the fund's board of directors has adopted a "purchase
blocking policy" under which any shareholder redeeming shares having a value of
$5,000 or more from the fund will be precluded from investing in the fund for 30
calendar days after the redemption transaction. This policy also applies to
redemptions and purchases that are part of exchange transactions. Under the
fund's purchase blocking policy, certain purchases will not be prevented and
certain redemptions will not trigger a purchase block, such as systematic
redemptions and purchases, where the entity maintaining the shareholder account
is able to identify the transaction as a systematic redemption or purchase;
purchases and redemptions of shares having a value of less than $5,000;
transactions in Class 529 shares; purchases and redemptions resulting from
reallocations by American Funds Target Date Retirement Series; retirement plan
contributions, loans and distributions (including hardship withdrawals)
identified as such on the retirement plan recordkeeper's system; and purchase
transactions involving transfers of assets, rollovers, Roth IRA conversions and
IRA recharacterizations, where the entity maintaining the shareholder account is
able to identify the transaction as one of these types of transactions.

The fund reserves the right to waive the purchase blocking policy with respect
to specific shareholder accounts in those instances where American Funds Service
Company determines that its surveillance procedures are adequate to detect
frequent trading in fund shares.

American Funds Service Company will work with certain intermediaries (such as
investment dealers holding shareholder accounts in street name, retirement plan
recordkeepers, insurance company separate accounts and bank trust companies) to
apply their own procedures, provided that American Funds Service Company
believes the intermediary's procedures are reasonably designed to enforce the
frequent trading policies of the fund. You should refer to disclosures provided
by the intermediaries with which you have an account to determine the specific
trading restrictions that apply to you.

If American Funds Service Company identifies any activity that may constitute
frequent trading, it reserves the right to contact the intermediary and request
that the intermediary either provide information regarding an account owner's
transactions or restrict the account owner's trading. If American Funds Service
Company is not satisfied that the intermediary has taken appropriate action,
American Funds Service Company may terminate the intermediary's ability to
transact in fund shares.

There is no guarantee that all instances of frequent trading in fund shares will
be prevented.

NOTWITHSTANDING THE FUND'S SURVEILLANCE PROCEDURES AND PURCHASE BLOCKING POLICY,
ALL TRANSACTIONS IN FUND SHARES REMAIN SUBJECT TO THE FUND'S AND AMERICAN FUNDS
DISTRIBUTORS' RIGHT TO RESTRICT POTENTIALLY ABUSIVE TRADING GENERALLY (INCLUDING
THE TYPES OF TRANSACTIONS DESCRIBED ABOVE THAT WILL NOT BE PREVENTED OR TRIGGER
A BLOCK UNDER THE PURCHASE BLOCKING POLICY). SEE THE STATEMENT OF ADDITIONAL
INFORMATION FOR MORE INFORMATION ABOUT HOW AMERICAN FUNDS SERVICE COMPANY MAY
ADDRESS OTHER POTENTIALLY ABUSIVE TRADING ACTIVITY IN THE AMERICAN FUNDS.

SALES

Please contact your plan administrator or recordkeeper in order to sell shares
from your retirement plan.

RIGHT OF REINVESTMENT

If you notify American Funds Service Company, you may reinvest proceeds from a
redemption, dividend payment or capital gain distribution without a sales charge
in the same fund or other American Funds, provided that the reinvestment occurs
within 90 days after the date of the redemption or distribution and is made into
the same account from which you redeemed the shares or received the
distribution. If the account has been closed, you may reinvest without a sales
charge if the new receiving account has the same registration as the closed
account. Proceeds will be reinvested in the same share class from which the
original redemption or distribution was made. Redemption proceeds of Class A
shares representing direct purchases in American Funds money market funds that
are reinvested in non-money market American Funds will be subject to a sales
charge. Proceeds will be reinvested at the next calculated net asset value after
your request is received and accepted by American Funds Service Company. For
purposes of this "right of reinvestment policy," automatic transactions
(including, for example, automatic purchases, withdrawals and payroll
deductions) and ongoing retirement plan

contributions are not eligible for investment without a sales charge. See the
statement of additional information for further information. You may not
reinvest proceeds in the American Funds as described in this paragraph if such
proceeds are subject to a purchase block as described under "Frequent trading of
fund shares" in this prospectus. This paragraph does not apply to certain
rollover investments as described under "Rollovers from retirement plans to
IRAs" in this prospectus.

VALUING SHARES

The net asset value of each share class of the fund is the value of a single
share. The fund calculates the net asset value each day the New York Stock
Exchange is open for trading as of approximately 4 p.m. New York time, the
normal close of regular trading. Assets are valued primarily on the basis of
market quotations. However, the fund has adopted procedures for making "fair
value" determinations if market quotations are not readily available or are not
considered reliable. For example, if events occur between the close of markets
outside the United States and the close of regular trading on the New York Stock
Exchange that, in the opinion of the investment adviser, materially affect the
value of any of the fund's securities that principally trade in those
international markets, those securities will be valued in accordance with fair
value procedures. Use of these procedures is intended to result in more
appropriate net asset values. In addition, such use will reduce, if not
eliminate, potential arbitrage opportunities otherwise available to short-term
investors.

Because the fund may hold securities that are primarily listed on foreign
exchanges that trade on weekends or days when the fund does not price its
shares, the value of securities held in the fund may change on days when you
will not be able to purchase or redeem fund shares.

Your shares will be purchased at the net asset value (plus any applicable sales
charge in the case of Class A shares) or sold at the net asset value next
determined after American Funds Service Company receives and accepts your
request.

MOVING BETWEEN SHARE CLASSES AND ACCOUNTS

Please see the statement of additional information for details and limitations
on moving investments in certain share classes to different share classes and on
moving investments held in certain accounts to different accounts.

Sales charges

CLASS A SHARES

The initial sales charge you pay each time you buy Class A shares differs
depending upon the amount you invest and may be reduced or eliminated for larger
purchases as indicated below. The "offering price," the price you pay to buy
shares, includes any applicable sales charge, which will be deducted directly
from your investment. Shares acquired through reinvestment of dividends or
capital gain distributions are not subject to an initial sales charge.

The sales charge, expressed as a percentage of the offering price or the net
amount invested, may be higher or lower than the percentages described in the
table above due to rounding. This is because the dollar amount of the sales
charge is determined by subtracting the net asset value of the shares purchased
from the offering price, which is calculated to two decimal places using
standard rounding criteria. The impact of rounding will vary with the size of
the investment and the net asset value of the shares.

CLASS A PURCHASES NOT SUBJECT TO SALES CHARGES

The following investments are not subject to any initial or contingent deferred
sales charge if American Funds Service Company is properly notified of the
nature of the investment:

. investments made by accounts that are part of certain qualified fee-based
  programs and that purchased Class A shares before the discontinuation of your
  investment dealer's load-waived Class A share program with the American Funds;
  and

. certain rollover investments from retirement plans to IRAs (see "Rollovers
  from retirement plans to IRAs" in this prospectus for more information).

                                        The Growth Fund of America / Prospectus
<PAGE>

The distributor may pay dealers up to 1% on investments made in Class A shares
with no initial sales charge. The fund may reimburse the distributor for these
payments through its plans of distribution (see "Plans of distribution" in this
prospectus).

Certain other investors may qualify to purchase shares without a sales charge,
such as employees of investment dealers and registered investment advisers
authorized to sell American Funds, and employees of The Capital Group Companies.
Please see the statement of additional information for more information.

 EMPLOYER-SPONSORED RETIREMENT PLANS

 Employer-sponsored retirement plans that are eligible to purchase Class R
 shares may instead purchase Class A shares and pay the applicable Class A sales
 charge, provided their recordkeepers can properly apply a sales charge on plan
 investments. These plans are not eligible to make initial purchases of $1
 million or more in Class A shares and thereby invest in Class A shares without
 a sales charge, nor are they eligible to establish a statement of intention
 that qualifies them to purchase Class A shares without a sales charge. More
 information about statements of intention can be found under "Sales charge
 reductions" in this prospectus. Plans investing in Class A shares with a sales
 charge may purchase additional Class A shares in accordance with the sales
 charge table in this prospectus.

 Employer-sponsored retirement plans that invested in Class A shares without any
 sales charge on or before March 31, 2004, and that continue to meet the
 eligibility requirements in effect as of that date for purchasing Class A
 shares at net asset value, may continue to purchase Class A shares without any
 initial or contingent deferred sales charge.

 A 403(b) plan may not invest in Class A or C shares, unless such plan was
 invested in Class A or C shares prior to January 1, 2009.

CLASS R SHARES

Class R shares are sold without any initial or contingent deferred sales charge.
The distributor will pay dealers annually an asset-based compensation of up to
1.00% for sales of Class R-1 shares, up to .75% for Class R-2 shares, up to .50%
for Class R-3 shares and up to .25% for Class R-4 shares. No dealer compensation
is paid from fund assets on sales of Class R-5 or R-6 shares. The fund may
reimburse the distributor for these payments through its plans of distribution
(see "Plans of distribution" in this prospectus).

Sales charge reductions

TO RECEIVE A REDUCTION IN YOUR CLASS A INITIAL SALES CHARGE, YOU MUST LET YOUR
FINANCIAL ADVISER OR AMERICAN FUNDS SERVICE COMPANY KNOW AT THE TIME YOU
PURCHASE SHARES THAT YOU QUALIFY FOR SUCH A REDUCTION. IF YOU DO NOT LET YOUR
ADVISER OR AMERICAN FUNDS SERVICE COMPANY KNOW THAT YOU ARE ELIGIBLE FOR A
REDUCTION, YOU MAY NOT RECEIVE A SALES CHARGE DISCOUNT TO WHICH YOU ARE
OTHERWISE ENTITLED. In order to determine your eligibility to receive a sales
charge discount, it may be necessary for you to provide your adviser or American
Funds Service Company with information and records (including account
statements) of all relevant accounts invested in the American Funds.

IN ADDITION TO THE INFORMATION IN THIS PROSPECTUS, YOU MAY OBTAIN MORE
INFORMATION ABOUT SHARE CLASSES, SALES CHARGES AND SALES CHARGE REDUCTIONS
THROUGH A LINK ON THE HOME PAGE OF THE AMERICAN FUNDS WEBSITE AT
AMERICANFUNDS.COM, FROM THE STATEMENT OF ADDITIONAL INFORMATION OR FROM YOUR
FINANCIAL ADVISER.

REDUCING YOUR CLASS A INITIAL SALES CHARGE

Consistent with the policies described in this prospectus, two or more
retirement plans of an employer or employer's affiliates may combine all of
their American Funds investments to reduce their Class A sales charge. Certain
investments in the American Funds Target Date Retirement Series may also be
combined for this purpose. Please see the American Funds Target Date Retirement
Series prospectus for further information. However, for this purpose,
investments representing direct purchases of American Funds money market funds
are excluded. Following are different ways that you may qualify for a reduced
Class A sales charge:

 CONCURRENT PURCHASES

 Simultaneous purchases of any class of shares of two or more American Funds
 (excluding American Funds money market funds) may be combined to qualify for a
 reduced Class A sales charge.

 RIGHTS OF ACCUMULATION

 You may take into account your accumulated holdings in all share classes of the
 American Funds (excluding American Funds money market funds) to determine the
 initial sales charge you pay on each purchase of Class A shares. Subject to
 your investment dealer's or recordkeeper's capabilities, your accumulated
 holdings will be calculated as the higher of (a) the current value of your
 existing holdings or (b) the amount you invested (including reinvested
 dividends and capital gains, but excluding capital appreciation) less any
 withdrawals. Please see the statement of additional information for further
 details. You should retain any records necessary to substantiate the historical
 amounts you have invested.

<PAGE>

 STATEMENT OF INTENTION

 You may reduce your Class A sales charge by establishing a statement of
 intention. A statement of intention allows you to combine all purchases of all
 share classes of the American Funds (excluding American Funds money market
 funds) you intend to make over a 13-month period to determine the applicable
 sales charge; however, purchases made under a right of reinvestment,
 appreciation of your holdings, and reinvested dividends and capital gains do
 not count as purchases made during the statement period. The market value of
 your existing holdings eligible to be aggregated as of the day immediately
 before the start of the statement period may be credited toward satisfying the
 statement. A portion of your account may be held in escrow to cover additional
 Class A sales charges that may be due if your total purchases over the
 statement period do not qualify you for the applicable sales charge reduction.
 Employer-sponsored retirement plans may be restricted from establishing
 statements of intention. See "Sales charges" in this prospectus for more
 information.

RIGHT OF REINVESTMENT

Please see the "Sales" section of "Purchase, exchange and sale of shares" in
this prospectus for information on how to reinvest proceeds from a redemption,
dividend payment or capital gain distribution without a sales charge.

Rollovers from retirement plans to IRAs

Assets from retirement plans may be invested in Class A, C or F shares
through an IRA rollover, subject to the other provisions of this prospectus and
the prospectus for nonretirement plan shareholders. More information on Class C
and F shares can be found in the fund's prospectus for nonretirement plan
shareholders. Rollovers invested in Class A shares from retirement plans will be
subject to applicable sales charges. The following rollovers to Class A shares
will be made without a sales charge:

. rollovers to IRAs from 403(b) plans with Capital Bank and Trust Company as
  custodian; and

. rollovers to IRAs that are attributable to American Funds investments, if they
  meet the following requirements:

  -- the assets being rolled over were invested in American Funds at the time of
     distribution; and

  -- the rolled over assets are contributed to an American Funds IRA with Capital
     Bank and Trust Company as custodian.

IRA rollover assets that roll over without a sales charge as described above
will not be subject to a contingent deferred sales charge and investment dealers
will be compensated solely with an annual service fee that begins to accrue
immediately. IRA rollover assets invested in Class A shares that are not
attributable to American Funds investments, as well as future contributions to
the IRA, will be subject to sales charges and the terms and conditions generally
applicable to Class A share investments as described in this prospectus and the
statement of additional information.

Plans of distribution

The fund has plans of distribution or "12b-1 plans" for certain share classes,
under which it may finance activities primarily intended to sell shares,
provided the categories of expenses are approved in advance by the fund's board
of directors. The plans provide for payments, based on annualized percentages of
average daily net assets, of up to .25% for Class A shares, up to 1.00% for
Class R-1 and R-2 shares, up to .75% for Class R-3 shares and up to .50% for
Class R-4 shares. For all share classes indicated above, up to .25% of these
expenses may be used to pay service fees to qualified dealers for providing
certain shareholder services. The amount remaining for each share class may be
used for distribution expenses.

The 12b-1 fees paid by the fund, as a percentage of average net assets for the
previous fiscal year, are indicated in the Annual Fund Operating Expenses table
under "Fees and expenses of the fund" in this prospectus. Since these fees are
paid out of the fund's assets or income on an ongoing basis, over time they will
increase the cost and reduce the return of your investment.

Other compensation to dealers

American Funds Distributors, at its expense, currently provides additional
compensation to investment dealers. These payments may be made, at the
discretion of American Funds Distributors, to the top 100 dealers (or their
affiliates) that have sold shares of the American Funds. The level of payments
made to a qualifying firm in any given year will vary and in no case would
exceed the sum of (a) .10% of the previous year's American Funds sales by that
dealer and (b) .02% of American Funds assets attributable to that dealer. For
calendar year 2008, aggregate payments made by American Funds Distributors to
dealers were less than .02% of the average assets of the American Funds.
Aggregate payments may also change from year to year. A number of factors will
be considered in determining payments, including the qualifying dealer's sales,
assets and redemption rates, and the quality of the dealer's relationship with
American Funds Distributors. American Funds Distributors makes these payments to
help defray the costs incurred by qualifying dealers in connection with efforts
to educate financial advisers about the American Funds so that they can make
recommendations and provide services that are suitable and meet shareholder
needs. American Funds Distributors will, on an annual basis, determine the
advisability of continuing these payments. American Funds Distributors may also
pay expenses associated with meetings conducted by dealers outside the top 100
firms to facilitate educating financial advisers and shareholders about the
American Funds. If investment advisers, distributors or other affiliates of
mutual funds pay additional compensation or other incentives in differing
amounts, dealer firms and their advisers may have financial incentives for
recommending a particular mutual fund over other mutual funds. You should
consult with your financial adviser and review carefully any disclosure by your
financial adviser's firm as to compensation received.

Distributions and taxes

DIVIDENDS AND DISTRIBUTIONS

The fund intends to distribute dividends to shareholders, usually in December.

Capital gains, if any, are usually distributed in December. When a dividend or
capital gain is distributed, the net asset value per share is reduced by the
amount of the payment.

All dividends and capital gain distributions paid to retirement plan
shareholders will be automatically reinvested.

TAXES ON DIVIDENDS AND DISTRIBUTIONS

Dividends and capital gains distributed by the fund to tax-deferred retirement
plan accounts are not taxable currently.

TAXES ON TRANSACTIONS

Exchanges within a tax-deferred retirement plan account will not result in a
capital gain or loss for federal or state income tax purposes. With limited
exceptions, distributions from a retirement plan account are taxable as ordinary
income.

PLEASE SEE YOUR TAX ADVISER FOR MORE INFORMATION.

Financial highlights

The Financial Highlights table is intended to help you understand the fund's
results for the past five fiscal years. Certain information reflects financial
results for a single share of a particular class. A similar table will be shown
for Class R-6 shares beginning with the fund's fiscal year ending after the date
the share class is first offered. The total returns in the table represent the
rate that an investor would have earned or lost on an investment in the fund
(assuming reinvestment of all dividends and capital gain distributions). Where
indicated, figures in the table reflect the impact, if any, of certain
reimbursements/waivers from Capital Research and Management Company. For more
information about these reimbursements/waivers, see the footnotes to the Annual
Fund Operating Expenses table under "Fees and expenses of the fund" in this
prospectus and the fund's annual report. The information in the Financial
Highlights table has been audited by Deloitte & Touche LLP, whose report, along
with the fund's financial statements, is included in the statement of additional
information, which is available upon request.
