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 expense
reimbursements. The examples assuming redemption do not reflect the effect of
any taxable gain or loss at the time of the redemption.

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

Principal investment strategies

The fund invests substantially in U.S. Treasury securities and other securities
backed by the full faith and credit of the United States government, as well as
securities issued by U.S. federal agencies. The fund may also invest in other
high-quality money market instruments.

The fund may invest in securities issued by entities domiciled outside of the
U.S. and securities with credit and liquidity support features provided by
entities domiciled outside of the U.S. The fund may also invest in securities of
U.S. issuers with substantial operations outside the United States.

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 provide current income while
preserving capital and maintaining liquidity. The investment adviser believes
that an important way to accomplish this is by analyzing various factors,
including the credit strength of the issuer, prices of similar securities issued
by comparable issuers, current and anticipated changes in interest rates,
general market conditions and other factors pertinent to the particular security
being evaluated.

The fund has entered into an Agreement and Plan of Reorganization and
Liquidation with The Cash Management Trust of America and The U.S. Treasury
Money Fund of America, or the target funds, to merge the target funds into the
fund in exchange for shares of beneficial interest of the fund, subject to the
approval of the target funds' shareholders. As of the date of this prospectus,
the target funds had a combined total asset value of approximately $34 billion.
These assets may be more or less as of the date of the completion of the
mergers, which the fund expects to be in summer 2009. If the mergers are
completed and the target funds are participants of the U.S. Treasury's Temporary
Guarantee Program for Money Market Funds at such time, shareholders of the
target funds that were insured under the program as of the completion of the
mergers will be covered by the program to the same extent in the fund. Under the
program, the Treasury is guaranteeing investors of any participating fund that
in the event the fund is liquidated they will receive $1.00 for the lesser of
(i) each share of the fund held in an account as of the close of business on
September 19, 2008 and (ii) each share of the fund held in that account on the
date the fund's net asset value falls below $0.9950. The guarantee does not
cover shares of a fund purchased after the close of business on September 19,
2008, to the extent the number of shares held in a particular account exceeds
the number of shares held in that account on September 19, 2008. The program is
currently operational until April 30, 2009, but may be extended by the Secretary
of the Treasury through September 19, 2009. The duration and terms of any such
extension have not been determined, and there is no assurance that either of the
target funds will participate in any such extension.

Principal risks

Although the fund seeks to preserve the value of your investment at $1.00 per
share, it is possible to lose money by investing in the fund.

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.

The value and liquidity of the securities held by the fund may be affected by
changing interest rates and by changes in credit ratings of the securities. For
example, the values of these securities may decline when interest rates rise and
increase when interest rates fall.

Some of the securities held by the fund may have credit and liquidity
enhancements. Changes in the credit quality of the issuer or provider of these
enhancements could cause the fund to experience a loss and may affect its share
price.

Additionally, the securities held by the fund may be affected by unfavorable
political, economic or governmental developments that could affect the repayment
of principal or the payment of interest.

You may generally open an account and purchase Class A and 529 shares by
contacting any financial adviser (who may impose transaction charges in addition
to those described in this prospectus) authorized to sell the fund's shares. You
may purchase additional shares in various ways, including through your financial
adviser and by mail, telephone, the Internet and bank wire. Class B and C shares
of the fund may be acquired only by exchanging from Class B and C shares of
other American Funds. Direct purchases of Class B and C shares of the fund are
not permitted. You may generally open an account and purchase Class F shares
only through fee-based programs of investment dealers that have special
agreements with the fund's distributor and through certain registered investment
advisers. These dealers and advisers typically charge ongoing fees for services
they provide.

purchase minimum of $1,000 may be waived if the purchases (including purchases
through exchanges from another fund) made under the plan are sufficient to
reach $1,000 within five months of account establishment. Additionally, the
initial purchase minimum of $1,000 will be waived for accounts established by
exchanging into the fund with shares from another fund.

The effective purchase maximums for Class 529-A, 529-C, 529-E and 529-F-1 shares
will reflect the maximum applicable contribution limits under state law. See the
applicable program description for more information.

You may sell (redeem) shares through your dealer or financial adviser by writing
to American Funds Service Company, writing checks, telephoning or faxing
American Funds Service Company or on our website (americanfunds.com). Your
shares will be purchased from you (or sold to you) at the net asset value next
determined after American Funds Service Company receives and accepts your
request. 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. The fund seeks to preserve the net asset value
of each share class at $1.00.

Tax information

For federal income tax purposes, dividends you receive from the fund will be
subject to tax, and some or all may be subject to state or local taxes (in each
case, unless you are exempt from taxation). Generally, redemptions, including
exchanges, will not result in a capital gain or loss for federal or state income
tax purposes.

Financial intermediary compensation

If you purchase the fund through a broker-dealer or other financial intermediary
(such as a bank), the fund and its related companies may pay the intermediary
for the sale of fund shares and related services. These payments may influence
the broker-dealer or other intermediary and your salesperson to recommend the
fund over another investment. Ask your salesperson or visit your financial
intermediary's website for more information.

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 portfolios and business affairs of the fund. The total management
fees to be paid by the fund for the current fiscal year, as a percentage of
average net assets, appear in the Annual Fund Operating Expenses table under
"Fees and expenses of the fund." A more detailed description of the investment
advisory and service agreement between the fund and the investment adviser is
included in the fund's statement of additional information, and a discussion
regarding the basis for its approval by the fund's board of trustees will be
contained in the fund's annual report to shareholders.

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 will be available on the American
Funds website at americanfunds.com. To reach this information, access the fund's
detailed information page on the website. 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. This information is available on the website until new information for
the next 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.

Choosing a share class

The fund offers different classes of shares through this prospectus. Class A, C
and F shares are available through various investment programs or accounts,
including many types of retirement plans. The services or share classes
available to you may vary depending upon how you wish to purchase shares of the
fund. Unless otherwise noted, references in this prospectus to Class F shares
refer to both Class F-1 and F-2 shares.

Investors residing in any state may purchase Class 529 shares through an account
established with a 529 college savings plan managed by the American Funds
organization. The 529-A, 529-B, 529-C and 529-F-1 share classes are structured
similarly to the corresponding Class A, B, C and F-1 shares. For example, the
same contingent deferred sales charge applies to Class 529-B shares as it does
to Class B shares. Class 529-E shares are available only to investors
participating through an eligible employer plan.

Each share class of a fund represents an investment in the same portfolio of
securities, but each class has its own sales charge and expense structure,
allowing you to choose the class that best fits your situation. WHEN YOU
PURCHASE SHARES OF THE FUND, YOU SHOULD CHOOSE A SHARE CLASS. IF NONE IS CHOSEN,
YOUR INVESTMENT WILL BE MADE IN CLASS A SHARES OR, IN THE CASE OF A 529 PLAN
INVESTMENT, CLASS 529-A SHARES.

Factors you should consider in choosing a class of shares include:

. whether you plan to take any distributions in the near future (for example,
the contingent deferred sales charge will not be waived if you sell your Class
529-B or 529-C shares to cover higher education expenses); and

. availability of share classes:

-- Class B, 529-B, C and 529-C shares may be acquired only by exchanging from
Class B, 529-B, C or 529-C shares of other American Funds (see "Purchase and
exchange of shares" below); and

-- Class F and 529-F-1 shares are generally available only to fee-based
programs of investment dealers that have special agreements with the fund's
distributor and to certain registered investment advisers.

EACH INVESTOR'S FINANCIAL CONSIDERATIONS ARE DIFFERENT. YOU SHOULD SPEAK WITH
YOUR FINANCIAL ADVISER TO HELP YOU DECIDE WHICH SHARE CLASS IS BEST FOR YOU.

UNLESS OTHERWISE NOTED, REFERENCES IN THE FOLLOWING PAGES TO CLASS A, B, C OR
F-1 SHARES ALSO REFER TO THE CORRESPONDING CLASS 529-A, 529-B, 529-C OR 529-F-1
SHARES.

Purchase and exchange of shares

THE FUND'S TRANSFER AGENT, ON BEHALF OF THE FUND AND AMERICAN FUNDS
DISTRIBUTORS,/(R)/ THE FUND'S DISTRIBUTOR, IS REQUIRED BY LAW TO OBTAIN
CERTAIN PERSONAL INFORMATION FROM YOU OR ANY OTHER PERSON(S) ACTING ON YOUR
BEHALF IN ORDER TO VERIFY YOUR OR SUCH PERSON'S IDENTITY. IF YOU DO NOT PROVIDE
THE INFORMATION, THE TRANSFER AGENT MAY NOT BE ABLE TO OPEN YOUR ACCOUNT. IF THE
TRANSFER AGENT IS UNABLE TO VERIFY YOUR IDENTITY OR THAT OF ANY OTHER PERSON(S)
AUTHORIZED TO ACT ON YOUR BEHALF, OR BELIEVES IT HAS IDENTIFIED POTENTIALLY
CRIMINAL ACTIVITY, THE FUND AND AMERICAN FUNDS DISTRIBUTORS RESERVE THE RIGHT TO
CLOSE YOUR ACCOUNT OR TAKE SUCH OTHER ACTION THEY DEEM REASONABLE OR REQUIRED BY
LAW.

When purchasing shares, you should designate the fund or funds in which you wish
to invest. If no fund is designated and the amount of your cash investment is
more than $5,000, your money will be held uninvested (without liability to the
transfer agent for loss of income or appreciation pending receipt of proper
instructions) until investment instructions are received, but for no more than
three business days. Your investment will be made at the net asset value (plus
any applicable sales charge in the case of Class A shares) next determined after
investment instructions are received and accepted by the transfer agent. If
investment instructions are not received, your money will be invested in Class A
shares of the American Funds Money Market Fund on the third business day after
receipt of your investment.

If no fund is designated and the amount of your cash investment is $5,000 or
less, your money will be invested in the same proportion and in the same fund or
funds in which your last cash investment (excluding exchanges) was made,
provided such investment was made within the last 16 months. If no investment
was made within the last 16 months, your money will be held uninvested (without
liability to the transfer agent for loss of income or appreciation pending
receipt of proper instructions) until investment instructions are received, but
for no more than three business days. Your investment will be made at the net
asset value (plus any applicable sales charge in the case of Class A shares)
next determined after investment instructions are received and accepted by the
transfer agent. If investment instructions are not received, your money will be
invested in Class A shares of the American Funds Money Market Fund on the third
business day after receipt of your investment.

PURCHASE OF CLASS A, B AND C SHARES

You may generally open an account and purchase Class A shares by contacting any
financial adviser (who may impose transaction charges in addition to those
described in this prospectus) authorized to sell the fund's shares. You may
purchase additional shares in various ways, including through your financial
adviser and by mail, telephone, the Internet and bank wire. Class B and C shares
of the fund may be acquired only by exchanging from Class B and C shares of
other American Funds. Direct purchases of Class B and C shares of the fund are
not permitted.

American Funds Money Market Fund / Prospectus

<PAGE>

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

PURCHASE OF CLASS F SHARES

You may generally open an account and purchase Class F shares only through
fee-based programs of investment dealers that have special agreements with the
fund's distributor and through certain registered investment advisers. These
dealers and advisers typically charge ongoing fees for services they provide.

PURCHASE OF CLASS 529 SHARES

Class 529 shares may be purchased only through an account established with a 529
college savings plan managed by the American Funds organization. You may open
this type of account and purchase 529 shares by contacting any financial adviser
(who may impose transaction charges in addition to those described in this
prospectus) authorized to sell such an account. You may purchase additional
shares in various ways, including through your financial adviser and by mail,
telephone, the Internet and bank wire.

Class 529-E shares may be purchased only by employees participating through an
eligible employer plan.

EXCHANGE

Generally, you may exchange your shares into shares of the same class of other
American Funds without a sales charge. However, exchanges from Class A shares of
the fund may be made into Class C shares of other American Funds for dollar cost
averaging purposes. Exchanges from Class A shares of the fund to Class C shares
of Intermediate Bond Fund of America, Limited Term Tax-Exempt Bond Fund of
America and Short-Term Bond Fund of America are not permitted. Class A, C or F-1
shares may generally be exchanged into the corresponding 529 share class without
a sales charge. Class B shares may not be exchanged into Class 529-B shares.
EXCHANGES FROM CLASS A, C OR F-1 SHARES TO THE CORRESPONDING 529 SHARE CLASS,
PARTICULARLY IN THE CASE OF UNIFORM GIFTS TO MINORS ACT OR UNIFORM TRANSFERS TO
MINORS ACT CUSTODIAL ACCOUNTS, MAY RESULT IN SIGNIFICANT LEGAL AND TAX
CONSEQUENCES AS DESCRIBED IN THE APPLICABLE PROGRAM DESCRIPTION. PLEASE CONSULT
YOUR FINANCIAL ADVISER BEFORE MAKING SUCH AN EXCHANGE.

Exchanges of shares from American Funds money market funds initially purchased
without a sales charge generally will be subject to the appropriate sales
charge. For purposes of computing the contingent deferred sales charge on Class
B and C shares, the length of time you have owned your shares will be measured
from the date of original purchase and will not be affected by any permitted
exchange.

Exchanges have the same tax consequences as ordinary sales and purchases. For
example, to the extent you exchange shares held in a taxable account that are
worth more now than what you paid for them, the gain will be subject to
taxation. See "Transactions by

American Funds Money Market Fund / Prospectus

telephone, fax or the Internet" in this prospectus for information regarding
electronic exchanges.

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.

The American Funds (other than the money market funds, including this fund) have
adopted a "purchase blocking policy" under which any shareholder redeeming
shares having a value of $5,000 or more from a fund (other than the money market
funds, including this fund) will be precluded from investing in that 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
American Funds' 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/(R)/; 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.

American Funds Money Market Fund / Prospectus

<PAGE>

Each 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 funds. 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 FUNDS' SURVEILLANCE PROCEDURES AND PURCHASE BLOCKING POLICY,
ALL TRANSACTIONS IN FUND SHARES REMAIN SUBJECT TO THE RIGHT OF THE FUND AND
AMERICAN FUNDS DISTRIBUTORS' 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.

VALUING SHARES

The net asset value of each share class of the fund is the value of a single
share. The fund seeks to preserve the net asset value of each share class at
$1.00. 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. The fund may also calculate its share price on
days the New York Stock Exchange is closed when deemed prudent to do so by the
fund's officers. 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, fair value procedures may be used if an issuer defaults and there
is no market for its securities. Use of these procedures is intended to result
in more appropriate net asset values.

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

American Funds Money Market Fund / Prospectus
<PAGE>

held in the fund may change on days when you will not be able to purchase or
redeem fund shares.

All securities with 60 days or less to maturity are amortized to maturity based
on their cost if acquired within 60 days of maturity, or if already held on the
60th day, based on the value determined on the 61st day. The maturities of
variable or floating rate instruments, with the right to resell them at an
agreed-upon price to the issuer or dealer, are deemed to be the time remaining
until the later of the next interest adjustment date or until they can be
resold.

If market prices or market quotations are not readily available or are
considered unreliable, securities are valued at fair value as determined in good
faith pursuant to procedures adopted by the board of trustees. The fair value of
all other assets is added to the value of securities to arrive at the total
assets.

Your shares will be purchased at the net asset value or sold at the net asset
value next determined after American Funds Service Company receives and accepts
your request. A contingent deferred sales charge may apply at the time you sell
certain Class B and C shares.

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.

American Funds Money Market Fund / Prospectus

Sales charges

CLASS A SHARES

Class A shares of the fund are sold without an initial sales charge. However, if
shares of the fund are exchanged for shares of an American Funds non-money
market fund, the sales charge applicable to the non-money market fund may apply.

CLASS B AND C SHARES

Class B and C shares are sold without any initial sales charge.

For Class B shares, a contingent deferred sales charge may be applied to shares
you sell within six years of purchase, as shown in the table below.

CONTINGENT DEFERRED SALES CHARGE ON CLASS B SHARES

YEAR OF REDEMPTION: 1 2 3 4 5 6 7+
----------------------------------------------------------------------
CONTINGENT DEFERRED SALES CHARGE: 5% 4% 4% 3% 2% 1% 0%

For Class C shares, a contingent deferred sales charge of 1% applies if shares
are sold within one year of purchase.

Any contingent deferred sales charge paid by you on investments in Class B or C
shares, expressed as a percentage of the applicable redemption amount, may be
higher or lower than the percentages described above due to rounding.

Shares acquired through reinvestment of dividends are not subject to a
contingent deferred sales charge. In addition, the contingent deferred sales
charge may be waived in certain circumstances. See "Contingent deferred sales
charge waivers" in this prospectus. The contingent deferred sales charge is
based on the original purchase cost or the current market value of the shares
being sold, whichever is less. For purposes of determining the contingent
deferred sales charge, if you sell only some of your shares, shares that are not
subject to any contingent deferred sales charge will be sold first, followed by
shares that you have owned the longest.

See "Plans of distribution" in this prospectus for ongoing compensation paid to
your dealer or financial adviser for all share classes.

AUTOMATIC CONVERSION OF CLASS B AND C SHARES

Class B shares automatically convert to Class A shares in the month of the
eight-year anniversary of the purchase date. Class C shares automatically
convert to Class F-1 shares in the month of the 10-year anniversary of the
purchase date; however, Class 529-C shares will not convert to Class 529-F-1
shares. The Internal Revenue Service currently takes the position that these
automatic conversions are not taxable. Should its position change, the automatic
conversion feature may be suspended. If this happens, you would have the option
of converting your Class B, 529-B or C shares to the respective share

American Funds Money Market Fund / Prospectus
<PAGE>

classes at the anniversary dates described above. This exchange would be based
on the relative net asset values of the two classes in question, without the
imposition of a sales charge or fee, but you might face certain tax consequences
as a result.

CLASS 529-E AND CLASS F SHARES

Class 529-E and Class F shares are sold without any initial or contingent
deferred sales charge.

American Funds Money Market Fund / Prospectus

<PAGE>

Sales charge waivers

To have your Class B or C contingent deferred sales charge waived, you must let
your financial adviser or American Funds Service Company know at the time you
redeem shares that you qualify for such a waiver.

CONTINGENT DEFERRED SALES CHARGE WAIVERS

The contingent deferred sales charge on Class B and C shares may be waived in
the following cases:

. permitted exchanges of shares, except if shares acquired by exchange are then
redeemed within the period during which a contingent deferred sales charge
would apply to the initial shares purchased;

. tax-free returns of excess contributions to IRAs;

. redemptions due to death or postpurchase disability of the shareholder (this
generally excludes accounts registered in the names of trusts and other
entities);

. for 529 share classes only, redemptions due to a beneficiary's death,
postpurchase disability or receipt of a scholarship (to the extent of the
scholarship award);

. redemptions due to the complete termination of a trust upon the death of the
trustor/ grantor or beneficiary, but only if such termination is specifically
provided for in the trust document; and

. the following types of transactions, if together they do not exceed 12% of the
value of an account annually:

-- redemptions due to receiving required minimum distributions from retirement
accounts upon reaching age 701/2 (required minimum distributions that
continue to be taken by the beneficiary(ies) after the account owner is
deceased also qualify for a waiver); and

-- if you have established an automatic withdrawal plan, redemptions through
such a plan (including any dividends and/or capital gain distributions taken
in cash).

Rollovers from retirement plans to IRAs

Assets from retirement plans may be invested in Class A, B, C or F shares
through an IRA rollover, subject to the other provisions of this prospectus.
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.

American Funds Money Market Fund / Prospectus

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 trustees. The plans provide for payments, based on annualized percentages of
average daily net assets, of up to .15% for Class A shares, up to .50% for Class
529-A shares, up to .90% for Class B and 529-B shares, up to 1.00% for Class C
and 529-C shares, up to .75% for Class 529-E shares and up to .50% for Class F-1
and 529-F-1 shares. A portion (up to .15% for Class A, 529-A, B and 529-B shares
and .25% for Class C, 529-C, 529-E, F-1 and 529-F-1 shares) 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 estimated 12b-1 fees to be paid by the fund, as a percentage of average net
assets for the current fiscal year, are indicated in the Annual Fund Operating
Expenses table under "Fees and expenses of the funds" 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.

American Funds Money Market Fund / Prospectus

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.

How to sell shares

You may sell (redeem) shares in any of the following ways:

THROUGH YOUR DEALER OR FINANCIAL ADVISER (CERTAIN CHARGES MAY APPLY)

. Shares held for you in your dealer's name must be sold through the dealer.

. Class F shares must be sold through your dealer or financial adviser.

WRITING TO AMERICAN FUNDS SERVICE COMPANY

. Requests must be signed by the registered shareholder(s).

. A signature guarantee is required if the redemption is:

-- more than $75,000;

-- made payable to someone other than the registered shareholder(s); or

-- sent to an address other than the address of record or to an address of
record that has been changed within the last 10 days.

. American Funds Service Company reserves the right to require signature
guarantee(s) on any redemption.

. Additional documentation may be required for redemptions of shares held in
corporate, partnership or fiduciary accounts.

CHECK WRITING

. Checks must be signed by the authorized number of registered shareholders
exactly as indicated on your checking account signature card.

. Check writing is not available for any of the 529 share classes or B, C and F
share classes.

TELEPHONING OR FAXING AMERICAN FUNDS SERVICE COMPANY OR USING THE INTERNET

. Redemptions by telephone, fax or the Internet (including American
FundsLine/(R)/ and americanfunds.com) are limited to $75,000 per American
Funds shareholder each day.

. Checks must be made payable to the registered shareholder.

. Checks must be mailed to an address of record that has been used with the
account for at least 10 days.

If you recently purchased shares and subsequently request a redemption of those
shares, you will receive proceeds from the redemption once a sufficient period
of time has passed to reasonably ensure that checks or drafts (including
certified or cashier's checks) for the shares purchased have cleared (normally
10 business days).

American Funds Money Market Fund / Prospectus
<PAGE>

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 from a Class B share redemption made during the contingent
deferred sales charge period will be reinvested in Class A shares. If you redeem
Class B shares after the contingent deferred sales charge period, you may either
reinvest the proceeds in Class B shares or purchase Class A shares; if you
purchase Class A shares, you are responsible for paying any applicable Class A
sales charges. Proceeds from any other type of redemption and all dividend
payments and capital gain distributions will be reinvested in the same share
class from which the original redemption or distribution was made. Any
contingent deferred sales charge on Class C shares will be credited to your
account. 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.

TRANSACTIONS BY TELEPHONE, FAX OR THE INTERNET

Generally, you are automatically eligible to redeem or exchange shares by
telephone, fax or the Internet, unless you notify us in writing that you do not
want any or all of these services. You may reinstate these services at any time.

Unless you decide not to have telephone, fax or Internet services on your
account(s), you agree to hold the fund, American Funds Service Company, any of
its affiliates or mutual funds managed by such affiliates, and each of their
respective directors, trustees, officers, employees and agents harmless from any
losses, expenses, costs or liabilities (including attorney fees) that may be
incurred in connection with the exercise of these privileges, provided American
Funds Service Company employs reasonable procedures to confirm that the
instructions received from any person with appropriate account information are
genuine. If reasonable procedures are not employed, American Funds Service
Company and/or the fund may be liable for losses due to unauthorized or
fraudulent instructions.

Dividends and taxes

DIVIDENDS

The fund declares daily dividends from net investment income and distributes the
accrued dividends, which may fluctuate, to you each month. Dividends begin
accruing one day after payment for shares is received by the fund or American
Funds Service Company.

You may elect to reinvest dividends to purchase additional shares of this fund
or other American Funds, or you may elect to receive them in cash. Dividends for
529 share classes will be automatically reinvested.

TAXES ON DIVIDENDS

For federal income tax purposes, dividends you receive from the fund will be
subject to tax, and also may be subject to state or local taxes -- unless you
are exempt from taxation.

TAXES ON TRANSACTIONS

Generally, redemptions of shares of the fund, including exchanges, will not
result in a capital gain or loss for federal or state income tax purposes.

SHAREHOLDER FEES

Fees borne directly by a fund normally have the effect of reducing a
shareholder's taxable income on distributions. By contrast, fees paid directly
to advisers by a fund shareholder for ongoing advice are deductible for income
tax purposes only to the extent that they (combined with certain other
qualifying expenses) exceed 2% of such shareholder's adjusted gross income.

PLEASE SEE YOUR TAX ADVISER FOR MORE INFORMATION. HOLDERS OF 529 SHARES SHOULD
REFER TO THE APPLICABLE PROGRAM DESCRIPTION FOR MORE INFORMATION REGARDING THE
TAX CONSEQUENCES OF SELLING 529 SHARES.

EXAMPLE

The example below is intended to help you compare the cost of investing in the
fund with the cost of investing in other mutual funds. The example assumes that
you invest $10,000 in each 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 each fund's operating expenses remain the
same as shown above.

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

CERTAIN INVESTMENT LIMITATIONS AND GUIDELINES

The following limitations and guidelines are considered at the time of purchase,
under normal circumstances, and are based on a percentage of the fund's net
assets unless otherwise noted. This summary is not intended to reflect all of
the fund's investment limitations.

DEBT SECURITIES

. The fund will invest substantially all of its assets in securities
rated in the highest short-term rating categories (i.e., Prime-1, A-1
and A-1+).

MATURITY

. The fund currently intends (over the next twelve months) to maintain a
dollar-weighted average portfolio maturity of approximately 75 days or
less. Additionally, the fund will not maintain a dollar-weighted
average portfolio maturity that exceeds 90 days.

INVESTING OUTSIDE THE U.S.

. The fund may invest a portion of its assets in U.S. dollar-denominated
securities issued by entities outside the U.S.

* * * * * *

The fund may experience difficulty liquidating certain portfolio securities
during significant market declines or periods of heavy redemptions.

DESCRIPTION OF CERTAIN SECURITIES AND INVESTMENT TECHNIQUES

The descriptions below are intended to supplement the material in the prospectus
under "Investment objective, strategies and risks."

INVESTMENT POLICIES -- The fund may invest in securities that are rated in the
two highest rating categories for debt obligations by at least two nationally
recognized statistical rating organizations (or one rating organization if the
instrument was rated by only one such organization) or, if unrated, are of
comparable quality as determined in accordance with procedures established by
the Board of Trustees ("eligible securities"). The nationally recognized
statistical rating organizations currently rating instruments of the type the
fund may purchase include Moody's Investors Service ("Moody's"), Standard &
Poor's Corporation ("S&P"), Fitch Ratings ("Fitch") and Dominion Bond Rating
Service ("DBRS"). Subsequent to its purchase, an issue of securities may cease
to be rated or its rating may be reduced below the minimum rating required for
its purchase. Neither event requires the elimination of such securities from the
fund's portfolio, but Capital Research and Management Company (the "investment
adviser") will consider such an event in its determination of whether the fund
should continue to hold the securities. Investments in eligible securities not
rated in the highest category by at least two rating organizations (or one
rating organization if the instrument was rated by only one such organization),
and unrated eligible securities not determined by the investment adviser to be
of comparable quality to those rated in the highest category, will be limited to
5% of the fund's total

American Funds Money Market Fund -- Page 2
<PAGE>

assets, with the investment in any one such issuer being limited to no more than
the greater of 1% of a fund's total assets or $1,000,000.

The fund invests in various high-quality money market instruments that mature,
or may be redeemed or resold, in 13 months or less (25 months or less in the
case of U.S. government securities).

OBLIGATIONS BACKED BY THE "FULL FAITH AND CREDIT" OF THE U.S. GOVERNMENT -- U.S.
government obligations include the following types of securities:

U.S. TREASURY SECURITIES -- U.S. Treasury securities include direct
obligations of the U.S. Treasury, such as Treasury bills, notes and bonds.
For these securities, the payment of principal and interest is
unconditionally guaranteed by the U.S. government, and thus they are of the
highest possible credit quality. Such securities are subject to variations
in market value due to fluctuations in interest rates, but, if held to
maturity, will be paid in full.

FEDERAL AGENCY SECURITIES -- The securities of certain U.S. government
agencies and government-sponsored entities are guaranteed as to the timely
payment of principal and interest by the full faith and credit of the U.S.
government. Such agencies and entities include the Government National
Mortgage Association (Ginnie Mae), the Veterans Administration (VA), the
Federal Housing Administration (FHA), the Export-Import Bank (Exim Bank),
the Overseas Private Investment Corporation (OPIC), the Commodity Credit
Corporation (CCC) and the Small Business Administration (SBA).

OTHER FEDERAL AGENCY OBLIGATIONS -- Additional federal agency securities are
neither direct obligations of, nor guaranteed by, the U.S. government. These
obligations include securities issued by certain U.S. government agencies and
government-sponsored entities. However, they generally involve some form of
federal sponsorship: some operate under a government charter; some are backed by
specific types of collateral; some are supported by the issuer's right to borrow
from the Treasury; and others are supported only by the credit of the issuing
government agency or entity. These agencies and entities include, but are not
limited to: Federal Home Loan Bank, Federal Home Loan Mortgage Corporation
(Freddie Mac), Federal National Mortgage Association (Fannie Mae), Tennessee
Valley Authority and Federal Farm Credit Bank System.

On September 7, 2008, Freddie Mac and Fannie Mae were placed into
conservatorship by their new regulator, the Federal Housing Finance Agency.
Simultaneously, the U.S. Treasury made a commitment of indefinite duration to
maintain the positive net worth of both firms.

REPURCHASE AGREEMENTS -- Repurchase agreements under which the fund buys a
security and obtains a simultaneous commitment from the seller to repurchase the
security at a specified time and price. Repurchase agreements permit the fund to
maintain liquidity and earn income over periods of time as short as overnight.
The seller must maintain with the fund's custodian collateral equal to at least
100% of the repurchase price, including accrued interest, as monitored daily by
the investment adviser. The fund will only enter into repurchase agreements
involving securities in which it could otherwise invest and with selected banks
and securities dealers whose financial condition is monitored by the investment
adviser. If the seller under the repurchase agreement defaults, the fund may
incur a loss if the value of the collateral securing the repurchase agreement
has declined and may incur disposition costs in connection with liquidating the
collateral. If bankruptcy proceedings are commenced with respect to the seller,
realization of the collateral by the fund may be delayed or limited.

American Funds Money Market Fund -- Page 3
<PAGE>

COMMERCIAL PAPER -- Short-term notes issued by companies, governmental bodies or
bank/ corporation sponsored conduits (asset-backed commercial paper).

4(2) COMMERCIAL PAPER -- Commercial paper issued pursuant to Section 4(2) of the
Securities Act of 1933 (the "1933 Act"). 4(2) commercial paper has substantially
the same price and liquidity characteristics as commercial paper generally,
except that the resale of 4(2) commercial paper is limited to the institutional
investor marketplace. Such a restriction on resale makes 4(2) commercial paper
technically a restricted security under the 1933 Act. In practice, however, 4(2)
commercial paper can be resold as easily as any other unrestricted security held
by the fund. Accordingly, 4(2) commercial paper has been determined to be liquid
under procedures adopted by the fund's board of directors.

SHORT-TERM BANK OBLIGATIONS -- Certificates of deposit (interest-bearing time
deposits), bank notes, bankers' acceptances (time drafts drawn on a commercial
bank where the bank accepts an irrevocable obligation to pay at maturity)
representing direct or contingent obligations of commercial banks. Commercial
banks issuing obligations in which the fund invests must be on an approved list
that is monitored on a regular basis.

GOVERNMENT SUPPORT FOR SHORT-TERM DEBT INSTRUMENTS -- Various agencies and
instrumentalities of the U.S. government and governments of other countries have
recently implemented or announced programs that support short-term debt
instruments, including commercial paper, in an attempt to sustain liquidity in
the markets for these securities. Following is a brief summary of some of these
programs (please refer to the applicable entity's website for further
information on the specific program). Entities issuing obligations supported by
these programs in which the fund invests must be on an approved list that is
monitored on a regular basis.

TEMPORARY LIQUIDITY GUARANTEE PROGRAM -- The FDIC will guarantee payment of
new senior unsecured debt issued by FDIC-insured depository institutions,
U.S. bank holding companies and financial holding companies and certain
U.S. savings and loan holding companies. The guarantee will cover all new
senior unsecured debt, including commercial paper, issued by these entities
on or before December 31, 2009. The guarantee will extend only until
December 31, 2012, even if the debt has not then matured.

COMMERCIAL PAPER FUNDING FACILITY (CPFF) -- The Federal Reserve Bank of New
York will lend money to a special purpose vehicle that will purchase
eligible commercial paper from eligible issuers from October 27, 2008 until
October 30, 2009. Under the CPFF, eligible issuers are U.S. domiciled
issuers of commercial paper (including those with parent companies outside
the U.S.) and eligible commercial paper must have a three month maturity,
be U.S. dollar denominated and be rated at least A-1/P-1/F1 by two or more
nationally recognized rating agencies.

ASSET BACKED COMMERCIAL PAPER MONEY MARKET FUND LIQUIDITY FACILITY (AMLF) -
The Federal Reserve Bank of Boston will lend money to eligible borrowers,
including U.S. depositary institutions, bank holding companies and U.S.
branches and agencies of foreign banks, in order to fund purchases of
eligible asset backed commercial paper from money market funds until
October 30, 2009. Under the AMLF, eligible asset backed commercial paper
must be issued by a U.S. issuer that was in existence on September 18,
2008, be U.S. dollar denominated, be rated at least A-1, P-1 or F1 by at
least two major

American Funds Money Market Fund -- Page 4
<PAGE>

rating agencies (or in the top rating category if rated by only one agency)
and have a maturity that does not exceed 120 days if the borrower is a bank
or 270 days for non-bank borrowers.

MONEY MARKET INVESTOR FUNDING FACILITY (MMIFF) -- In addition to the CPFF,
the Federal Reserve Bank of New York will lend money to a series of special
purpose vehicles to purchase eligible assets from eligible investors. Under
the MMIFF, eligible investors are U.S. money market funds and eligible
assets include U.S. dollar-denominated certificates of deposit, bank notes
and commercial paper with a remaining maturity of 90 days or less issued by
the financial institutions designated in operational documents of the
special purpose vehicles. The special purpose vehicles will purchase the
eligible assets with funds from the Federal Reserve Bank of New York and
the issuance of asset backed commercial paper to the eligible investor. The
MMIFF will run through October 30, 2009.

GOVERNMENT GUARANTEES OUTSIDE THE U.S. -- Various governments outside the
U.S. have implemented or announced programs under which the government or a
government agency will guarantee debt, including commercial paper, of
financial institutions in that country.

CORPORATE BONDS AND NOTES -- Corporate obligations include those that mature, or
may be redeemed by the fund, in 13 months or less. These obligations may
originally have been issued with maturities in excess of 13 months. The fund
currently may invest only in corporate bonds or notes of issuers having
outstanding short-term securities rated in the top rating category and long-term
ratings of A- or better, in each case by Moody's, S&P, Fitch or DBRS. See the
appendix for a description of high-quality ratings by Moody's, S&P, Fitch and
DBRS.

LOANS OF PORTFOLIO SECURITIES -- The fund is authorized to lend portfolio
securities to selected securities dealers or other institutional investors whose
financial condition is monitored by the investment adviser. The borrower must
maintain with the fund's custodian collateral consisting of cash, cash
equivalents or U.S. government securities equal to at least 100% of the value of
the borrowed securities, plus any accrued interest. The investment adviser will
monitor the adequacy of the collateral on a daily basis. The fund may at any
time call a loan of its portfolio securities and obtain the return of the loaned
securities. The fund will receive any interest paid on the loaned securities and
a fee or a portion of the interest earned on the collateral. The fund will limit
its loans of portfolio securities to an aggregate of 10% of the value of its
total assets, measured at the time any such loan is made.

INVESTING OUTSIDE THE UNITED STATES -- The fund may invest in securities issued
by entities domiciled outside the United States or in securities with credit and
liquidity support features provided by entities domiciled outside the United
States. Since these securities are issued by entities that may have substantial
operations outside the United States, they may involve additional risks and
considerations. These securities may be affected by unfavorable political,
economic or governmental developments that could affect the repayment of
principal or payment of interest. Securities of U.S. issuers with substantial
operations outside the United States may also be subject to similar risks.

VARIABLE AND FLOATING RATE OBLIGATIONS -- The interest rates payable on certain
securities in which the fund may invest may not be fixed but may fluctuate based
upon changes in market rates or credit ratings. Variable and floating rate
obligations bear coupon rates that are adjusted

American Funds Money Market Fund -- Page 5
<PAGE>

at designated intervals, based on the then current market rates of interest or
credit ratings. The rate adjustment features tend to limit the extent to which
the market value of the obligations will fluctuate.

PUT SECURITIES -- The fund may purchase securities that provide for the right to
resell them to the issuer, a bank or a broker-dealer, typically at the par value
plus accrued interest within a specified period of time prior to maturity. This
right is commonly known as a "put" or a "demand feature." The fund may pay a
higher price for such securities than would otherwise be paid for the same
security without such a right. The fund will enter into these transactions only
with issuers, banks or broker-dealers that are determined by the investment
adviser to present minimal credit risks. If an issuer, bank or broker-dealer
should default on its obligation to repurchase, the fund may be unable to
recover all or a portion of any loss sustained. There is no specific limit on
the extent to which the fund may invest in such securities.

MATURITY -- The fund determines its net asset value using the penny-rounding
method, according to rules of the Securities and Exchange Commission ("SEC"),
which permits it to maintain a constant net asset value of $1.00 per share under
normal conditions. In accordance with rule 2a-7 under the Investment Company Act
of 1940, as amended, the fund is required to maintain a dollar-weighted average
portfolio maturity of 90 days or less and purchase only instruments having
remaining maturities of 13 months or less (25 months or less in the case of U.S.
government securities) determined in accordance with procedures established by
the board of trustees to present minimal credit risks. For this purpose, certain
variable and floating rate obligations and put securities which may otherwise
have stated maturities in excess of 13 months (25 months in the case of U.S.
government securities) will be deemed to have remaining maturities equal to the
period remaining until each next readjustment of the interest rate or until the
fund is entitled to repayment or repurchase of the security.

FORWARD COMMITMENT, WHEN ISSUED AND DELAYED DELIVERY TRANSACTIONS -- The fund
may enter into commitments to purchase or sell securities at a future date. When
the fund agrees to purchase such securities, it assumes the risk of any decline
in value of the security from the date of the agreement. If the other party to
such a transaction fails to deliver or pay for the securities, the fund could
miss a favorable price or yield opportunity, or could experience a loss.

The fund will not use these transactions for the purpose of leveraging and will
segregate liquid assets that will be marked to market daily in an amount
sufficient to meet its payment obligations in these transactions. Although these
transactions will not be entered into for leveraging purposes, to the extent the
fund's aggregate commitments in connection with these transactions exceed its
segregated assets, the fund temporarily could be in a leveraged position
(because it may have an amount greater than its net assets subject to market
risk). Should market values of the fund's portfolio securities decline while the
fund is in a leveraged position, greater depreciation of its net assets would
likely occur than if it were not in such a position. The fund will not borrow
money to settle these transactions and, therefore, will liquidate other
portfolio securities in advance of settlement if necessary to generate
additional cash to meet its obligations. After a transaction is entered into,
the fund may still dispose of or renegotiate the transaction. Additionally,
prior to receiving delivery of securities as part of a transaction, the fund may
sell such securities.

FUND POLICIES

All percentage limitations in the following fund policies are considered at the
time securities are purchased and are based on the fund's net assets unless
otherwise indicated. None of the following policies involving a maximum
percentage of assets will be considered violated unless the excess occurs
immediately after, and is caused by, an acquisition by the fund. In managing the
fund, the fund's investment adviser may apply more restrictive policies than
those listed below.

FUNDAMENTAL POLICIES -- The fund has adopted the following fundamental policies,
which may not be changed without approval by holders of a majority of its
outstanding shares. Such majority is defined in the Investment Company Act of
1940, as amended (the "1940 Act"), as the vote of the lesser of (a) 67% or more
of the voting securities present at a shareholder meeting, if the holders of
more than 50% of the outstanding voting securities are present in person or by
proxy, or (b) more than 50% of the outstanding voting securities.

1. The fund may not borrow money except as permitted by (i) the 1940 Act and
the rules and regulations thereunder, or other successor law governing the

jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC
staff or other authority of competent jurisdiction.

2. The fund may not issue senior securities except as permitted by (i) the

permitted by (i) the 1940 Act and the rules and regulations thereunder, or other
successor law governing the regulation of registered investment companies, or
interpretations or modifications thereof by the SEC, SEC staff or other
authority of competent jurisdiction, or (ii) exemptive or other relief or
permission from the SEC, SEC staff or other authority of competent jurisdiction.

4. The fund may not purchase or sell real estate or commodities except as
permitted by (i) the 1940 Act and the rules and regulations thereunder, or other
successor law governing the regulation of registered investment companies, or
interpretations or modifications thereof by the SEC, SEC staff or other
authority of competent jurisdiction, or (ii) exemptive or other relief or
permission from the SEC, SEC staff or other authority of competent jurisdiction.

5. The fund may not make loans except as permitted by (i) the 1940 Act and the
rules and regulations thereunder, or other successor law governing the
regulation of registered investment companies, or interpretations or
modifications thereof by the SEC, SEC staff or other authority of competent
jurisdiction, or (ii) exemptive or other relief or permission from the SEC, SEC
staff or other authority of competent jurisdiction.

6. Except as permitted by (i) the 1940 Act and the rules and regulations
thereunder, or other successor law governing the regulation of registered
investment companies, or interpretations or modifications thereof by the SEC,
SEC staff or other authority of competent jurisdiction, or (ii) exemptive or
other relief or permission from the SEC, SEC staff or other authority of
competent

jurisdiction, the fund may not purchase the securities of any issuer if, as a
result of such purchase, the fund's investments would be concentrated in any
particular industry or group of industries, except that the fund may invest
without limitation in U.S. government securities and bank obligations.

7. The fund may not invest in companies for the purpose of exercising control
or management.

NONFUNDAMENTAL POLICIES -- The following policies may be changed by the board of
trustees without shareholder approval:

1. The fund may not invest more than 10% of its net assets in securities which
are not readily marketable.

2. The fund may not invest in securities of other investment companies, except
as permitted by the 1940 Act.

3. The fund may not acquire securities of open-end investment companies or
unit investment trusts registered under the 1940 Act in reliance on Sections
12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act.

ADDITIONAL INFORMATION ABOUT FUNDAMENTAL POLICIES -- The information below is
not part of the fund's fundamental policies. This information is intended to
provide a summary of what is currently required or permitted by the 1940 Act and
the rules and regulations thereunder, or by the interpretive guidance thereof by
the SEC or SEC staff, for particular fundamental policies of the fund.

For purposes of fundamental policy 1, the fund may borrow money in amounts of up
to 33-1/3% of its total assets from banks for any purpose, and may borrow up to
5% of its total assets from banks or other lenders for temporary purposes.

For purposes of fundamental policy 5, the fund may not lend more than 1/3 of its
total assets, except through the purchase of debt obligations or the use of
repurchase agreements.

For purposes of fundamental policy 6, the fund may not invest 25% or more of its
total assets in the securities of issuers in the same industry, except that the
fund may invest without limitation in securities of the United States government
or its agencies or instrumentalities and obligations of U.S. banks, including
U.S. branches of banks based outside the United States (e.g., certificates of
deposit, interest bearing time deposits, bank notes and banker's acceptances).
The fund invests in such obligations using the investment criteria of, and in
compliance with, Rule 2(a)(7) under the 1940 Act. In evaluating and selecting
such investments, the investment adviser, on behalf of the fund, uses the
criteria set forth under the headings "Certain investment limitations and
guidelines" and "Description of certain securities and investment techniques" in
this statement of additional information.

3 Dr. Mitchell became a director in the American Funds family on March 19, 2009.

TRUSTEE COMPENSATION -- No compensation is paid by the fund to any officer or
trustee who is a director, officer or employee of the investment adviser or its
affiliates. The boards of funds advised by the investment adviser typically meet
either individually or jointly with the boards of one or more other such funds
with substantially overlapping board membership (in each case referred to as a
"board cluster"). The fund typically pays each independent trustee an annual fee
based primarily on the total number of board clusters on which that independent
trustee serves.

In addition, the fund generally pays independent trustees attendance and other
fees for meetings of the board and its committees. Board and committee chairs
receive additional fees for their services.

Independent trustees also receive attendance fees for certain special joint
meetings and information sessions with directors and trustees of other groupings
of funds advised by the investment adviser. The fund and the other funds served
by each independent trustee each pay an equal portion of these attendance fees.

No pension or retirement benefits are accrued as part of fund expenses.
Independent trustees may elect, on a voluntary basis, to defer all or a portion
of their fees through a deferred compensation plan in effect for the fund. The
fund also reimburses certain expenses of the independent trustees.

3 Dr. Mitchell became a director in the American Funds family on March 19, 2009.

FUND ORGANIZATION AND THE BOARD OF TRUSTEES -- The fund, an open-end,
diversified management investment company, was organized as a Delaware statutory
trust on February 4, 2009.

Delaware law charges trustees with the duty of managing the business affairs of
the Trust. Trustees are considered to be fiduciaries of the Trust and must act
with the care, skill, prudence and diligence under the circumstances then
prevailing that a prudent person acting in a like capacity and familiar with
such matters would use to attain the purposes of the Trust.

The fund has several different classes of shares. Shares of each class represent
an interest in the same investment portfolio. Each class has pro rata rights as
to voting, redemption, dividends and liquidation, except that each class bears
different distribution expenses and may bear different transfer agent fees and
other expenses properly attributable to the particular class as approved by the
board of trustees and set forth in the fund's rule 18f-3 Plan. Each class'
shareholders have exclusive voting rights with respect to the respective class'
rule 12b-1 plans adopted in connection with the distribution of shares and on
other matters in which the interests of such classes are different from the
interests of other classes. Shares of all classes of the fund vote together on
matters that affect all classes in substantially the same manner. Each class

American Funds Money Market Fund -- Page 14
<PAGE>

votes as a class on matters that affect that class alone. Note that 529 college
savings plan account owners invested in Class 529 shares are not shareholders of
the fund and, accordingly, do not have the rights of a shareholder, such as the
right to vote proxies relating to fund shares. As the legal owner of the fund's
Class 529 shares, the Virginia College Savings Plan/SM/ will vote any proxies
relating to the fund's Class 529 shares. In addition, the trustees have the
authority to establish new series and classes of shares, and to split or combine
outstanding shares into a greater or lesser number, without shareholder
approval.

The fund does not hold annual meetings of shareholders. However, significant
matters that require shareholder approval, such as certain elections of board
members or a change in a fundamental investment policy, will be presented to
shareholders at a meeting called for such purpose. Shareholders have one vote
per share owned. At the request of the holders of at least 10% of the shares,
the fund will hold a meeting at which any member of the board could be removed
by a majority vote.

The fund's declaration of trust and by-laws as well as separate indemnification
agreements that the fund has entered into with its independent trustees provide
in effect that, subject to certain conditions, the fund will indemnify its
officers and trustees against liabilities or expenses actually and reasonably
incurred by them relating to their service to the fund. However, neither
officers nor trustees are protected from liability by reason of their willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of their office.

COMMITTEES OF THE BOARD OF TRUSTEES -- The fund has an audit committee comprised
of Richard G. Capen, Jr.; H. Frederick Christie; Leonard R. Fuller; R. Clark
Hooper; Laurel B. Mitchell; and Steadman Upham, none of whom is an "interested
person" of the fund within the meaning of the 1940 Act. The committee provides
oversight regarding the fund's accounting and financial reporting policies and
practices, the fund's internal controls and the internal controls of the fund's
principal service providers. The committee acts as a liaison between the fund's
independent registered public accounting firm and the full board of trustees.

The fund has a contracts committee comprised of Richard G. Capen, Jr.; H.
Frederick Christie; James G. Ellis; Martin Fenton; Leonard R. Fuller; R. Clark
Hooper; Laurel B. Mitchell; Richard G. Newman; Frank M. Sanchez; and Steadman
Upham, none of whom is an "interested person" of the fund within the meaning of
the 1940 Act. The committee's principal function is to request, review and
consider the information deemed necessary to evaluate the terms of certain
agreements between the fund and its investment adviser or the investment
adviser's affiliates, such as the Investment Advisory and Service Agreement,
Principal Underwriting Agreement, Administrative Services Agreement and Plans of
Distribution adopted pursuant to rule 12b-1 under the 1940 Act, that the fund
may enter into, renew or continue, and to make its recommendations to the full
board of trustees on these matters.

The fund has a nominating and governance committee comprised of Richard G.
Capen, Jr.; H. Frederick Christie; James G. Ellis; Martin Fenton; Leonard R.
Fuller; R. Clark Hooper; Richard G. Newman; Frank M. Sanchez; and Steadman
Upham, none of whom is an "interested person" of the fund within the meaning of
the 1940 Act. The committee periodically reviews such issues as the board's
composition, responsibilities, committees, compensation and other relevant
issues, and recommends any appropriate changes to the full board of trustees.
The committee also evaluates, selects and nominates independent trustee
candidates to the full board of trustees. While the committee normally is able
to identify from its own and other resources an ample number of qualified
candidates, it will consider shareholder suggestions of persons to be

American Funds Money Market Fund -- Page 15
<PAGE>

considered as nominees to fill future vacancies on the board. Such suggestions
must be sent in writing to the nominating and governance committee of the fund,
addressed to the fund's secretary, and must 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 committee.

PROXY VOTING PROCEDURES AND PRINCIPLES -- The fund's investment adviser, in
consultation with the fund's board, has adopted Proxy Voting Procedures and
Principles (the "Principles") with respect to voting proxies of securities held
by the fund, other American Funds, Endowments and American Funds Insurance
Series. The complete text of these principles is available on the American Funds
website at americanfunds.com. Certain American Funds have established separate
proxy voting committees that vote proxies or delegate to a voting officer the
authority to vote on behalf of those funds. Proxies for all other funds
(including the fund) are voted by a committee of the appropriate equity
investment division of the investment adviser under authority delegated by those
funds' boards. Therefore, if more than one fund invests in the same company,
they may vote differently on the same proposal.

All U.S. proxies are voted. Proxies for companies outside the U.S. also are
voted, provided there is sufficient time and information available. After a
proxy statement is received, the investment adviser prepares a summary of the
proposals contained in the proxy statement. A discussion of any potential
conflicts of interest also is included in the summary. For proxies of securities
managed by a particular investment division of the investment adviser, the
initial voting recommendation is made by one or more of the division's
investment analysts familiar with the company and industry. A second
recommendation is made by a proxy coordinator (an investment analyst with
experience in corporate governance and proxy voting matters) within the
appropriate investment division, based on knowledge of these Principles and
familiarity with proxy-related issues. The proxy summary and voting
recommendations are made available to the appropriate proxy voting committee for
a final voting decision.

The analyst and proxy coordinator making voting recommendations are responsible
for noting any potential material conflicts of interest. One example might be
where a director of one or more American Funds is also a director of a company
whose proxy is being voted. In such instances, proxy voting committee members
are alerted to the potential conflict. The proxy voting committee may then elect
to vote the proxy or seek a third-party recommendation or vote of an ad hoc
group of committee members.

The Principles, which have been in effect in substantially their current form
for many years, provide an important framework for analysis and decision-making
by all funds. However, they are not exhaustive and do not address all potential
issues. The Principles provide a certain amount of flexibility so that all
relevant facts and circumstances can be considered in connection with every
vote. As a result, each proxy received is voted on a case-by-case basis
considering the specific circumstances of each proposal. The voting process
reflects the funds' understanding of the company's business, its management and
its relationship with shareholders over time.

Information regarding how the fund voted proxies relating to portfolio
securities during the 12-month period ended June 30 of each year will be
available on or about September 1 of each year (a) without charge, upon request
by calling American Funds Service Company at 800/421-0180, (b) on the American
Funds website and (c) on the SEC's website at sec.gov.

American Funds Money Market Fund -- Page 16
<PAGE>

The following summary sets forth the general positions of the American Funds,
Endowments, American Funds Insurance Series and the investment adviser on
various proposals. A copy of the full Principles is available upon request, free
of charge, by calling American Funds Service Company or visiting the American
Funds website.

DIRECTOR MATTERS -- The election of a company's slate of nominees for
director generally is supported. Votes may be withheld for some or all of
the nominees if this is determined to be in the best interest of
shareholders. Separation of the chairman and CEO positions also may be
supported.

GOVERNANCE PROVISIONS -- Typically, proposals to declassify a board (elect
all directors annually) are supported based on the belief that this
increases the directors' sense of accountability to shareholders. Proposals
for cumulative voting generally are supported in order to promote
management and board accountability and an opportunity for leadership
change. Proposals designed to make director elections more meaningful,
either by requiring a majority vote or by requiring any director receiving
more withhold votes than affirmative votes to tender his or her
resignation, generally are supported.

SHAREHOLDER RIGHTS -- Proposals to repeal an existing poison pill generally
are supported. (There may be certain circumstances, however, when a proxy
voting committee of a fund or an investment division of the investment
adviser believes that a company needs to maintain anti-takeover
protection.) Proposals to eliminate the right of shareholders to act by
written consent or to take away a shareholder's right to call a special
meeting typically are not supported.

COMPENSATION AND BENEFIT PLANS -- Option plans are complicated, and many
factors are considered in evaluating a plan. Each plan is evaluated based
on protecting shareholder interests and a knowledge of the company and its
management. Considerations include the pricing (or repricing) of options
awarded under the plan and the impact of dilution on existing shareholders
from past and future equity awards. Compensation packages should be
structured to attract, motivate and retain existing employees and qualified
directors; however, they should not be excessive.

ROUTINE MATTERS -- The ratification of auditors, procedural matters
relating to the annual meeting and changes to company name are examples of
items considered routine. Such items generally are voted in favor of
management's recommendations unless circumstances indicate otherwise.

INVESTMENT ADVISER -- Capital Research and Management Company, the fund's
investment adviser, founded in 1931, maintains research facilities in the United
States and abroad (Los Angeles, San Francisco, New York, Washington, DC, London,
Geneva, Hong Kong, Singapore and Tokyo). These facilities are staffed with
experienced investment professionals. The investment adviser is located at 333
South Hope Street, Los Angeles, CA 90071 and 6455 Irvine Center Drive, Irvine,
CA 92618. It is a wholly owned subsidiary of The Capital Group Companies, Inc.,
a holding company for several investment management subsidiaries. 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.

American Funds Money Market Fund -- Page 17
<PAGE>

INVESTMENT ADVISORY AND SERVICE AGREEMENTS -- The Investment Advisory and
Service Agreement (the "Agreement") between the fund and the investment adviser
will continue in effect until October 31, 2010, unless sooner terminated and may
be renewed from year to year thereafter, provided that any such renewal has been
specifically approved at least annually by (a) the board of trustees, or by the
vote of a majority (as defined in the 1940 Act) of the outstanding voting
securities of the fund, and (b) the vote of a majority of trustees who are not
parties to the Agreement or interested persons (as defined in the 1940 Act) of
any such party, cast in person at a meeting called for the purpose of voting on
such approval. The Agreement provide that the investment adviser has no
liability to the fund for its acts or omissions in the performance of its
obligations to the fund not involving willful misconduct, bad faith, gross
negligence or reckless disregard of its obligations under the Agreement. The
Agreement also provide that either party has the right to terminate it, without
penalty, upon 60 days' written notice to the other party, and that the Agreement
automatically terminates in the event of its assignment (as defined in the 1940
Act).

In addition to providing investment advisory services, the investment adviser
furnishes the services and pays the compensation and travel expenses of persons
to perform the fund's executive, administrative, clerical and bookkeeping
functions, and provides suitable office space, necessary small office equipment
and utilities, general purpose accounting forms, supplies and postage used at
the fund's offices. The fund pays all expenses not assumed by the investment
adviser, including, but not limited to: custodian, stock transfer and dividend
disbursing fees and expenses; shareholder recordkeeping and administrative
expenses; costs of the designing, printing and mailing of reports, prospectuses,
proxy statements and notices to its shareholders; taxes; expenses of the
issuance and redemption of fund shares (including stock certificates,
registration and qualification fees and expenses); expenses pursuant to the
fund's plans of distribution (described below); legal and auditing expenses;
compensation, fees and expenses paid to independent trustees; association dues;
costs of stationery and forms prepared exclusively for the fund; and costs of
assembling and storing shareholder account data.

The management fee is based on the following annualized rates and net asset
levels:

ADMINISTRATIVE SERVICES AGREEMENTS -- The Administrative Services Agreement (the
"Administrative Agreements") between the fund and the investment adviser
relating to the fund's Class C, F, R and 529 shares will continue in effect
until October 31, 2009, unless sooner terminated, and may be renewed from year
to year thereafter, provided that any such renewal has been specifically
approved at least annually by the vote of a majority of trustees who are not
parties to the Administrative Agreement or interested persons (as defined in the
1940 Act) of any such party, cast in person at a meeting called for the purpose
of voting on such approval. The fund may terminate the Administrative Agreement
at any time by vote of a majority of the independent trustees. The investment
adviser has the right to terminate its Administrative Agreement upon 60 days'
written notice to the fund. The Administrative Agreement automatically
terminates in the event of its assignment (as defined in the 1940 Act).

Under the Administrative Agreement, the investment adviser provides certain
transfer agent and administrative services for shareholders of the fund's Class
C, F, R, Class 529 shares. The investment adviser may contract with third
parties, including American Funds Service Company,/(R)/ the fund's Transfer
Agent, to provide some of these services. Services include, but are not limited
to, shareholder account maintenance, transaction processing, tax information
reporting, and shareholder and fund communications. In addition, the investment
adviser monitors, coordinates, oversees and assists with the activities
performed by third parties providing such services.

The investment adviser receives an administrative services fee at the annual
rate of up to 0.15% of the average daily net assets for Class C, F, R (excluding
Class R-5 and R-6) and 529 shares for administrative services provided to these
share classes. Administrative services fees are paid monthly and accrued daily.
The investment adviser uses a portion of this fee to compensate third parties
for administrative services provided to the fund. Of the remainder, the
investment adviser will not retain more than 0.05% of the average daily net
assets for each applicable share class. For Class R-5 and R-6 shares, the
administrative services fee is calculated at the annual rate of up to 0.10% and
0.05%, respectively, of the average daily net assets of such class. The
administrative services fee includes compensation for transfer agent and
shareholder services provided to the fund's applicable share classes. In
addition to making administrative service fee payments to unaffiliated third
parties, the investment adviser also makes payments from the administrative
services fee to American Funds Service Company according to a fee schedule,
based principally on the number of accounts serviced, contained in a Shareholder
Services Agreement between the fund and American Funds Service Company. A
portion of the fees paid to American Funds Service Company for transfer agent
services is also paid directly from the relevant share class.

PRINCIPAL UNDERWRITER AND PLANS OF DISTRIBUTION -- American Funds
Distributors,/(R)/ Inc. (the "Principal Underwriter") is the principal
underwriter of the fund's shares. The Principal Underwriter is located at 333
South Hope Street, Los Angeles, CA 90071; 6455 Irvine Center Drive, Irvine, CA
92618; 3500 Wiseman Boulevard, San Antonio, TX 78251; 8332 Woodfield Crossing
Boulevard, Indianapolis, IN 46240; and 5300 Robin Hood Road, Norfolk, VA 23513.

The Principal Underwriter receives revenues relating to sales of the fund's
shares, as follows:

. For Class B and 529-B shares, the Principal Underwriter sells its
rights to the 0.75% distribution-related portion of the 12b-1 fees
paid by the fund, as well as any contingent deferred sales charges, to
a third party. The Principal Underwriter compensates investment
dealers for sales of Class B and 529-B shares out of the

American Funds Money Market Fund -- Page 19
<PAGE>

proceeds of this sale and keeps any amounts remaining after this
compensation is paid.

. For Class C and 529-C shares, the Principal Underwriter receives any
contingent deferred sales charges that apply during the first year
after purchase.

In addition, the fund reimburses the Principal Underwriter for advancing
immediate service fees to qualified dealers and advisers upon the sale of Class
B, 529-B, C and 529-C shares. The fund also reimburses the Principal Underwriter
for service fees (and, in the case of Class 529-E shares, commissions) paid on a
quarterly basis to qualified dealers and advisers in connection with investments
in its Class F-1, 529-F-1 and 529-E shares. The fund reimburses the Principal
Underwriter for services fees paid on a quarterly basis to qualified dealers and
advisers in connection with investments in their R-1, R-2, R-3 and R-4 shares
respectively.

Plans of distribution -- The fund has adopted plans of distribution (the
"Plans") pursuant to rule 12b-1 under the 1940 Act. The Plans permit the fund to
expend amounts to finance any activity primarily intended to result in the sale
of fund shares, provided the fund's board of trustees has approved the category
of expenses for which payment is being made.

Each Plan is specific to a particular share class of the fund. As the fund has
not adopted a Plan for Class F-2, Class R-5 or Class R-6, no 12b-1 fees are paid
from Class F-2, Class R-5 or Class R-6 share assets and the following disclosure
is not applicable to these share classes.

Payments under the Plans may be made for service-related and/or
distribution-related expenses. Service-related expenses include paying service
fees to qualified dealers. Distribution-related expenses include commissions
paid to qualified dealers. The amounts actually paid under the Plans for the
past fiscal year, expressed as a percentage of the fund's average daily net
assets attributable to the applicable share class, are disclosed in the
prospectus under "Fees and expenses of the fund." Further information regarding
the amounts available under each Plan is in the "Plans of Distribution" section
of the prospectus.

Following is a brief description of the Plans:

CLASS A AND 529-A -- For Class A shares and 529-A shares, up to 0.15% of
the fund's average daily net assets attributable to such shares is
reimbursed to the Principal Underwriter for paying service-related
expenses. The fund may annually expend up to 0.15% for Class A shares and
up to 0.50% for Class 529-A shares under the applicable Plan.

CLASS B AND 529-B -- The Plans for Class B and 529-B shares provide for
payments to the Principal Underwriter of up to 0.15% of the fund's average
daily net assets attributable to such shares for paying service-related
expenses and 0.75% for distribution-related expenses, which include the
financing of commissions paid to qualified dealers.

OTHER SHARE CLASSES (CLASS C, 529-C, F-1, 529-F-1, 529-E, R-1, R-2, R-3 AND
R-4) -- The Plans for each of the other share classes that have adopted
Plans provide for payments to the Principal Underwriter for paying
service-related and distribution-related expenses of up to the following
amounts of the fund's average daily net assets attributable to such shares:

1Amounts in these columns represent the amounts approved by the board of
trustees under the applicable Plan.
2The fund may annually expend the amounts set forth in this column under
the current Plans with the approval of the board of trustees.

Approval of the Plans -- As required by rule 12b-1 and the 1940 Act, the Plans
(together with the Principal Underwriting Agreement) have been approved by the
full board of trustees and separately by a majority of the independent trustees
of the fund who have no direct or indirect financial interest in the operation
of the Plans or the Principal Underwriting Agreement. In addition, the selection
and nomination of independent trustees of the fund is committed to the
discretion of the independent trustees during the existence of the Plans.

Potential benefits of the Plans to the fund include quality shareholder
services, savings to the fund in transfer agency costs, and benefits to the
investment process from growth or stability of assets. The Plans may not be
amended to materially increase the amount spent for distribution without
shareholder approval. Plan expenses are reviewed quarterly by the board of

EXECUTION OF PORTFOLIO TRANSACTIONS

The investment adviser places orders with broker-dealers for the fund's
portfolio transactions. Purchases and sales of equity securities on a securities
exchange or an over-the-counter market are effected through broker-dealers who
receive commissions for their services. Generally, commissions relating to
securities traded on foreign exchanges will be higher than commissions relating
to securities traded on U.S. exchanges and may not be subject to negotiation.
Equity securities may also be purchased from underwriters at prices that include
underwriting fees. Purchases and sales of fixed-income securities are generally
made with an issuer or a primary market-maker acting as principal with no stated
brokerage commission. The price paid to an underwriter for fixed-income
securities includes underwriting fees. Prices for fixed-income securities in
secondary trades usually include undisclosed compensation to the market-maker
reflecting the spread between the bid and ask prices for the securities.

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. These factors include the size and type of

American Funds Money Market Fund -- Page 23
<PAGE>

transaction, the nature and character of the markets for the security to be
purchased or sold, the cost, quality and reliability of the executions and the
broker-dealer's ability to offer liquidity and anonymity. The investment adviser
considers these factors, which involve qualitative judgments, when selecting
broker-dealers and execution venues for fund portfolio transactions. The
investment adviser views best execution as a process that should be evaluated
over time as part of an overall relationship with particular broker-dealer firms
rather than on a trade-by-trade basis. The fund does not consider the investment
adviser as having an obligation to obtain the lowest commission rate available
for a portfolio transaction to the exclusion of price, service and qualitative
considerations.

The investment adviser may execute portfolio transactions with broker-dealers
who provide certain brokerage and/or investment research services to it, but
only when in the investment adviser's judgment the broker-dealer is capable of
providing best execution for that transaction. The receipt of these services
permits the investment adviser to supplement its own research and analysis and
makes available the views of, and information from, individuals and the research
staffs of other firms. Such views and information may be provided in the form of
written reports, telephone contacts and meetings with securities analysts. These
services may include, among other things, reports and other communications with
respect to individual companies, industries, countries and regions, economic,
political and legal developments, as well as scheduling meetings with corporate
executives and seminars and conferences related to relevant subject matters. The
investment adviser considers these services to be supplemental to its own
internal research efforts and therefore the receipt of investment research from
broker-dealers does not tend to reduce the expenses involved in the investment
adviser's research efforts. If broker-dealers were to discontinue providing such
services it is unlikely the investment adviser would attempt to replicate them
on its own, in part because they would then no longer provide an independent,
supplemental viewpoint. Nonetheless, if it were to attempt to do so, the
investment adviser would incur substantial additional costs. Research services
that the investment adviser receives from broker-dealers may be used by the
investment adviser in servicing the fund and other funds and accounts that it
advises; however, not all such services will necessarily benefit the fund.

The investment adviser may pay commissions in excess of what other
broker-dealers might have charged - including on an execution-only basis - for
certain portfolio transactions in recognition of brokerage and/or investment
research services provided by a broker-dealer. In this regard, the investment
adviser has adopted a brokerage allocation procedure consistent with the
requirements of Section 28(e) of the U.S. Securities Exchange Act of 1934.
Section 28(e) permits an investment adviser to cause an account to pay a higher
commission to a broker-dealer that provides certain brokerage and/or investment
research services to the investment adviser, if the investment adviser makes a
good faith determination that such commissions are reasonable in relation to the
value of the services provided by such broker-dealer to the investment adviser
in terms of that particular transaction or the investment adviser's overall
responsibility to the fund and other accounts that it advises. Certain brokerage
and/or investment research services may not necessarily benefit all accounts
paying commissions to each such broker-dealer; therefore, the investment adviser
assesses the reasonableness of commissions in light of the total brokerage and
investment research services provided by each particular broker-dealer.

In accordance with its internal brokerage allocation procedure, each equity
investment division of the investment adviser periodically assesses the
brokerage and investment research services provided by each broker-dealer from
which it receives such services. Using its judgment, each equity investment
division of the investment adviser then creates lists with suggested levels of

American Funds Money Market Fund -- Page 24
<PAGE>

commissions for particular broker-dealers and provides those lists to its
trading desks. Neither the investment adviser nor the fund incurs any obligation
to any broker-dealer to pay for research by generating trading commissions. The
actual level of business received by any broker-dealer may be less than the
suggested level of commissions and can, and often does, exceed the suggested
level in the normal course of business. As part of its ongoing relationships
with broker-dealers, the investment adviser routinely meets with firms,
typically at the firm's request, to discuss the level and quality of the
brokerage and research services provided, as well as the perceived value and
cost of such services. In valuing the brokerage and investment research services
the investment adviser receives from broker-dealers in connection with its good
faith determination of reasonableness, the investment adviser does not attribute
a dollar value to such services, but rather takes various factors into
consideration, including the quantity, quality and usefulness of the services to
the investment adviser.

The investment adviser seeks, on an ongoing basis, to determine what the
reasonable levels of commission rates are in the marketplace. The investment
adviser takes various considerations into account when evaluating such
reasonableness, including, (a) rates quoted by broker-dealers, (b) the size of a
particular transaction in terms of the number of shares and dollar amount, (c)
the complexity of a particular transaction, (d) the nature and character of the
markets on which a particular trade takes place, (e) the ability of a
broker-dealer to provide anonymity while executing trades, (f) the ability of a
broker-dealer to execute large trades while minimizing market impact, (g) the
extent to which a broker-dealer has put its own capital at risk, (h) the level
and type of business done with a particular broker-dealer over a period of time,
(i) historical commission rates, and (j) commission rates that other
institutional investors are paying.

When executing portfolio transactions in the same equity security for the funds
and accounts, or portions of funds and accounts, over which the investment
adviser, through its equity investment divisions, has investment discretion,
each of the investment divisions will normally aggregate its respective
purchases or sales and execute them as part of the same transaction or series of
transactions. When executing portfolio transactions in the same fixed-income
security for the fund and the other funds or accounts over which it or one of
its affiliated companies has investment discretion, the investment adviser will
normally aggregate such purchases or sales and execute them as part of the same
transaction or series of transactions. The objective of aggregating purchases
and sales of a security is to allocate executions in an equitable manner among
the funds and other accounts that have concurrently authorized a transaction in
such security.

The investment adviser may place orders for the fund's portfolio transactions
with broker-dealers who have sold shares of the funds managed by the investment
adviser or its affiliated companies; however, it does not consider 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.

The fund is required to disclose information regarding investments in the
securities of its "regular" broker-dealers (or parent companies of its regular
broker-dealers) that derive more than 15% of their revenue from broker-dealer,
underwriter or investment adviser activities. A regular broker-dealer is (a) one
of the 10 broker-dealers that received from the fund the largest amount of
brokerage commissions by participating, directly or indirectly, in the fund's
portfolio transactions during the fund's most recent fiscal year; (b) one of the
10 broker-dealers that engaged as principal in the largest dollar amount of
portfolio transactions of the fund during the fund's most

American Funds Money Market Fund -- Page 25
<PAGE>

recent fiscal year; or (c) one of the 10 broker-dealers that sold the largest
amount of securities of the fund during the fund's most recent fiscal year.

DISCLOSURE OF PORTFOLIO HOLDINGS

The fund's investment adviser, on behalf of the fund, has adopted policies and
procedures with respect to the disclosure of information about fund portfolio
securities. These policies and procedures have been reviewed by the fund's board
of trustees and compliance will be periodically assessed by the board in
connection with reporting from the fund's Chief Compliance Officer.

Under these policies and procedures, the fund's complete list of portfolio
holdings available for public disclosure, dated as of the end of each calendar
quarter, is permitted to be posted on the American Funds website no earlier than
the tenth day after such calendar quarter. In practice, the public portfolio
typically is posted on the website approximately 45 days after the end of the
calendar quarter. Such portfolio holdings information may then be disclosed to
any person pursuant to an ongoing arrangement to disclose portfolio holdings
information to such person no earlier than one day after the day on which the
information is posted on the American Funds website. The fund's custodian,
outside counsel and auditor, each of which requires portfolio holdings
information for legitimate business and fund oversight purposes, may receive the
information earlier.

Affiliated persons of the fund, including officers of the fund and employees of
the investment adviser and its affiliates, who receive portfolio holdings
information are subject to restrictions and limitations on the use and handling
of such information pursuant to applicable codes of ethics, including
requirements not to trade in securities based on confidential and proprietary
investment information, to maintain the confidentiality of such information, and
to preclear securities trades and report securities transactions activity, as
applicable. For more information on these restrictions and limitations, please
see the "Code of Ethics" section in this statement of additional information and
the Code of Ethics. Third party service providers of the fund, as described in
this statement of additional information, receiving such information are subject
to confidentiality obligations. When portfolio holdings information is disclosed
other than through the American Funds website to persons not affiliated with the
fund (which, as described above, would typically occur no earlier than one day
after the day on which the information is posted on the American Funds website),
such persons will be bound by agreements (including confidentiality agreements)
or fiduciary obligations that restrict and limit their use of the information to
legitimate business uses only. Neither the fund nor its investment adviser or
any affiliate thereof receives compensation or other consideration in connection
with the disclosure of information about portfolio securities.

Subject to board policies, the authority to disclose a fund's portfolio
holdings, and to establish policies with respect to such disclosure, resides
with the appropriate investment-related committees of the fund's investment
adviser. In exercising their authority, the committees determine whether
disclosure of information about the fund's portfolio securities is appropriate
and in the best interest of fund shareholders. The investment adviser has
implemented policies and procedures to address conflicts of interest that may
arise from the disclosure of fund holdings. For example, the investment
adviser's code of ethics specifically requires, among other things, the
safeguarding of information about fund holdings and contains prohibitions
designed to prevent the personal use of confidential, proprietary investment
information in a way that would conflict with fund transactions. In addition,
the investment adviser believes that its current policy

American Funds Money Market Fund -- Page 26
<PAGE>

of not selling portfolio holdings information and not disclosing such
information to unaffiliated third parties until such holdings have been made
public on the American Funds website (other than to certain fund service
providers for legitimate business and fund oversight purposes) helps reduce
potential conflicts of interest between fund shareholders and the investment
adviser and its affiliates.

PRICE OF SHARES

Shares are purchased at the offering price (normally $1.00) or sold at the net
asset value price next determined after the purchase or sell order is received
and accepted by the fund or the Transfer Agent; the offering or net asset value
price is effective for orders received prior to the time of determination of the
net asset value and, in the case of orders placed with dealers or their
authorized designees, accepted by the Principal Underwriter, the Transfer Agent,
a dealer or any of their designees. In the case of orders sent directly to the
fund or the Transfer Agent, an investment dealer should be indicated. The dealer
is responsible for promptly transmitting purchase and sell orders to the
Principal Underwriter.

Orders received by the investment dealer or authorized designee, the Transfer
Agent or the fund after the time of the determination of the net asset value
will be entered at the next calculated offering price. Note that investment
dealers or other intermediaries may have their own rules about share
transactions and may have earlier cut-off times than those of the fund. For more
information about how to purchase through your intermediary, contact your
intermediary directly.

Orders received by the investment dealer or authorized designee, the Transfer
Agent, or the fund after the time of the determination of the net asset value
will be entered at the next calculated offering price. Prices that appear in the
newspaper do not always indicate prices at which you will be purchasing and
redeeming shares of the fund, since such prices generally reflect the previous
day's closing price whereas purchases and redemptions are made at the next
calculated price. The price you pay for shares, the offering price, is based on
the net asset value per share which is calculated once daily as of approximately
4 p.m. New York time, which is the normal close of trading on the New York Stock
Exchange, each day the Exchange is open. If, for example, the Exchange closes at
1 p.m., the fund's share price would still be determined as of 4 p.m. New York
time. The New York Stock Exchange is currently closed on weekends and on the
following holidays: New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas Day.

In case of orders sent directly to a fund or American Funds Service Company, an
investment dealer MUST be indicated. Any purchase order may be rejected by the
Principal Underwriter or by the funds.

The valuation of the fund's portfolio securities and calculation of its net
asset value are based upon the penny-rounding method of pricing pursuant to
Securities and Exchange Commission regulations, which permits current net asset
value per share to be rounded to the nearest cent. Under the Securities and
Exchange Commission regulations permitting the use of the penny-rounding method
of pricing, the fund must maintain a dollar-weighted average portfolio maturity
of 90 days or less, purchase instruments having remaining maturities of 13
months or less only (25 months or less in the case of U.S. government
securities), and invest only in securities determined by the board of trustees
to be of high quality with minimal credit risks. The fund follows standard
industry practice by typically reflecting changes in its holdings of portfolio
securities on the first business day following a portfolio trade.

American Funds Money Market Fund -- Page 27
<PAGE>

1. All securities with 60 days or less to maturity are amortized to maturity
based on their cost if acquired within 60 days of maturity, or if already held
on the 60th day, based on the value determined on the 61st day. The maturities
of variable or floating rate instruments, with the right to resell them at an
agreed-upon price to the issuer or dealer, are deemed to be the time remaining
until the later of the next interest adjustment date or until they can be
resold.

Other securities with more than 60 days remaining to maturity are valued at
prices obtained from one or more pricing vendors selected by the investment
adviser, except that, if such prices are not available or if the Investment
Adviser has determined that such prices do not reflect current market value,
they are valued in good faith at the mean between bid and ask quotations that
are reasonably and timely available from one or more dealers in such securities.
The pricing vendors base bond prices on, among other things, valuation matrices
which may incorporate dealer-supplied valuations, electronic data processing
techniques and an evaluation of the yield curve as of approximately 3 p.m. New
York time. The fund's investment adviser performs certain checks on these prices
prior to calculation of the fund's net asset value.

2. Liabilities, including proper accruals of expense items attributable to
particular share classes, are deducted from total assets attributable to such
share classes; and

3. Net assets so obtained for each share class are then divided by the total
number of shares outstanding of that share class, and the result, rounded to the
nearer cent, is the net asset value per share for that share class. The net
asset value of each share will normally remain constant at $1.00.

TAXES AND DISTRIBUTIONS

FUND TAXATION -- The fund has elected to be treated as a regulated investment
company under Subchapter M of the Internal Revenue Code (the "Code"). A
regulated investment company qualifying under Subchapter M of the Code is
required to distribute to its shareholders at least 90% of its investment
company taxable income (including the excess of net short-term capital gain over
net long-term capital losses) and generally is not subject to federal income tax
to the extent that it distributes annually 100% of its investment company
taxable income and net realized capital gains in the manner required under the
Code. The fund intends to distribute annually all of its investment company
taxable income and net realized capital gains and therefore does not expect to
pay federal income tax, although in certain circumstances the fund may determine
that it is in the interest of shareholders to distribute less than that amount.

To be treated as a regulated investment company under Subchapter M of the Code,
the fund must also (a) derive at least 90% of its gross income from dividends,
interest, payments with respect to securities loans, net income from certain
publicly traded partnerships and gains from the sale or other disposition of
securities or foreign currencies, or other income (including, but not limited
to, gains from options, futures or forward contracts) derived with respect to
the business of investing in such securities or currencies, and (b) diversify
its holdings so that, at the end of each fiscal quarter, (i) at least 50% of the
market value of the fund's assets is represented by cash, U.S. government
securities and securities of other regulated investment companies, and

American Funds Money Market Fund -- Page 28
<PAGE>

other securities (for purposes of this calculation, generally limited in respect
of any one issuer, to an amount not greater than 5% of the market value of the
fund's assets and 10% of the outstanding voting securities of such issuer) and
(ii) not more than 25% of the value of its assets is invested in the securities
of any one issuer (other than U.S. government securities or the securities of
other regulated investment companies), two or more issuers which the fund
controls and which are determined to be engaged in the same or similar trades or
businesses or the securities of certain publicly traded partnerships.

Under the Code, a nondeductible excise tax of 4% is imposed on the excess of a
regulated investment company's "required distribution" for the calendar year
ending within the regulated investment company's taxable year over the
"distributed amount" for such calendar year. The term "required distribution"
means the sum of (a) 98% of ordinary income (generally net investment income)
for the calendar year, (b) 98% of capital gain (both long-term and short-term)
for the one-year period ending on October 31 (as though the one-year period
ending on October 31 were the regulated investment company's taxable year) and
(c) the sum of any untaxed, undistributed net investment income and net capital
gains of the regulated investment company for prior periods. The term
"distributed amount" generally means the sum of (a) amounts actually distributed
by the fund from its current year's ordinary income and capital gain net income
and (b) any amount on which the fund pays income tax during the periods
described above. Although the fund intends to distribute its net investment
income and net capital gains so as to avoid excise tax liability, the fund may
determine that it is in the interest of shareholders to distribute a lesser
amount.

The following information may not apply to you if you hold fund shares in a
tax-deferred account, such as a retirement plan or education savings account.
Please see your tax adviser for more information.

DIVIDENDS -- Dividends on fund shares will be reinvested in shares of the fund
of the same class. Dividends distributed by the fund to a retirement plan
currently are not taxable.

The fund intends to follow the practice of distributing substantially all of its
investment company taxable income. Investment company taxable income generally
includes dividends, interest and net short-term capital gains, less expenses.

DAILY DIVIDENDS -- A dividend from net investment income is declared each day on
shares of the fund. This dividend is payable to everyone who was a shareholder
at the close of business the previous day. Accordingly, when shares are
purchased dividends begin to accrue on the day following receipt by the Transfer
Agent of payment for the shares; when shares are redeemed, the shares are
entitled to the dividend declared on the day the redemption request is received
by the Transfer Agent. Dividends are automatically reinvested in shares of the
same class, on the last business day of the month, at net asset value (without
sales charge), unless a shareholder otherwise instructs the Transfer Agent in
writing. Shareholders so requesting will be mailed checks in the amount of the
accumulated dividends.

Under the penny-rounding method of pricing (see "Purchase of Shares"), the fund
rounds its per share net asset value to the nearer cent to maintain a stable net
asset value of $1.00 per share. Accordingly its share price ordinarily would not
reflect realized or unrealized gains or losses unless such gains or losses were
to cause the net asset value to deviate from $1.00 by one half-cent or more.
Pursuant to Securities and Exchange Commission regulations, the Trustees have
undertaken, as a particular responsibility within their overall duty of care
owed to

American Funds Money Market Fund -- Page 29
<PAGE>

shareholders, to assure to the extent reasonably practicable that the fund's net
asset value per share, rounded to the nearer cent, will not deviate from $1.00.
Among the steps that could be taken to maintain the net asset value at $1.00
when realized or unrealized gains or losses approach one half-cent per share
would be to reflect all or a portion of such gains or losses in the daily
dividends declared. This would cause the amount of the daily dividends to
fluctuate and to deviate from the fund's net investment income for those days,
and could cause the dividend for a particular day to be negative. In that event
a fund would offset any such amount against the dividends that had been accrued
but not yet paid for that month. Alternatively, the fund has reserved the right
to adjust its total number of shares outstanding, if deemed advisable by the
Trustees, in order to maintain the net asset value of its shares at $1.00. This
would be done either by regarding each shareholder as having contributed to the
capital of the fund the number of full and fractional shares that
proportionately represents the excess, thereby reducing the number of
outstanding shares, or by declaring a stock dividend and increasing the number
of outstanding shares. Each shareholder will be deemed to have agreed to such
procedure by investing in the fund. Such action would not change a shareholder's
pro rata share of net assets, but would reflect the increase or decrease in the
value of the shareholder's holdings which resulted from the change in net asset
value.

The fund does not ordinarily realize short- or long-term capital gains or losses
on sales of securities. If a fund should realize gains or losses, it would
distribute to shareholders all of the excess of net long-term capital gain over
net short-term capital loss on sales of securities. Although the fund generally
maintains a stable net asset value of $1.00 per share, if the net asset value of
shares of a fund should, by reason of a distribution of realized capital gains,
be reduced below a shareholder's cost, such distribution would in effect be a
return of capital to that shareholder even though taxable to the shareholder,
and a sale of shares by a shareholder at net asset value at that time would
establish a capital loss for federal tax purposes. See also "Purchase of Shares"
below.

STATE TAXES -- Since some of the fund's dividends are expected to be
attributable to income on U.S. Treasury securities, that portion may be exempt
from state personal income taxes. Also, some states do not have personal income
taxes. The fund believes that, as of the date of this publication, neither the
District of Columbia nor any state imposes an income tax on dividends
attributable to income on U.S. Treasury securities paid by the fund to
individuals. However, other taxes may apply to dividends paid by the fund to
individual shareholders. Further, any distributions of capital gains may not be
exempt from income taxes. Because tax laws vary from state to state and may
change over time, you should consult your tax adviser or state tax authorities
regarding the tax status of distributions from the fund. Corporate shareholders
may be subject to income tax or other types of tax on dividends they receive,
even in those states that do not impose an income tax on distributions to
individual shareholders of the fund. Corporate shareholders should therefore
seek advice from their tax adviser regarding the tax treatment of distributions
from the fund.

accounts); and

. Employer-sponsored CollegeAmerica accounts.

The following account types may be established without meeting the initial
purchase minimum:

. Retirement accounts that are funded with employer contributions; and

. Accounts that are funded with monies set by court decree.

American Funds Money Market Fund -- Page 32
<PAGE>

The following account types may be established without meeting the initial
purchase minimum, but shareholders wishing to invest in two or more funds must
meet the normal initial purchase minimum of each fund:

. Accounts that are funded with (a) transfers of assets, (b) rollovers
from retirement plans, (c) rollovers from 529 college savings plans or
(d) required minimum distribution automatic exchanges; and

. American Funds money market fund accounts registered in the name of
clients of Capital Guardian Trust Company's Personal Investment
Management group.

Certain accounts held on the fund's books, known as omnibus accounts, contain
multiple underlying accounts that are invested in shares of the fund. These
underlying accounts are maintained by entities such as financial intermediaries
and are subject to the applicable initial purchase minimums as described in the
prospectus and this statement of additional information. However, in the case
where the entity maintaining these accounts aggregates the accounts' purchase
orders for fund shares, such accounts are not required to meet the fund's
minimum amount for subsequent purchases.

EXCHANGES -- You may only exchange shares into other American Funds within the
same share class. However, exchanges from Class A shares of the American Funds
Money Market Fund may be made to Class C shares of other American Funds for
dollar cost averaging purposes. Exchanges are not permitted from Class A shares
of the American Funds Money Market Fund to Class C shares of Intermediate Bond
Fund of America, Limited Term Tax-Exempt Bond Fund of America or Short-Term Bond
Fund of America. Exchange purchases are subject to the minimum investment
requirements of the fund purchased and no sales charge generally applies.
However, exchanges of shares from American Funds money market funds are subject
to applicable sales charges on the fund being purchased, unless the money market
fund shares were acquired by an exchange from a fund having a sales charge, or
by reinvestment or cross-reinvestment of dividends or capital gain
distributions. Exchanges of Class F shares generally may only be made through
fee-based programs of investment firms that have special agreements with the
fund's distributor and certain registered investment advisers.

You may exchange shares of other classes by contacting the Transfer Agent, by
contacting your investment dealer or financial adviser, by using American
FundsLine or americanfunds.com, or by telephoning 800/421-0180 toll-free, or
faxing (see "American Funds Service Company service areas" in the prospectus for
the appropriate fax numbers) the Transfer Agent. For more information, see
"Shareholder account services and privileges" in this statement of additional
information. THESE TRANSACTIONS HAVE THE SAME TAX CONSEQUENCES AS ORDINARY SALES
AND PURCHASES.

Shares held in employer-sponsored retirement plans may be exchanged into other
American Funds by contacting your plan administrator or recordkeeper. Exchange
redemptions and purchases are processed simultaneously at the share prices next
determined after the exchange order is received (see "Price of shares" in this
statement of additional information).

CONVERSION -- Currently, Class C shares of the fund automatically convert to
Class F-1 shares in the month of the 10-year anniversary of the purchase date.
The board of trustees of the fund reserves the right at any time, without
shareholder approval, to amend the conversion feature of the Class C shares,
including without limitation, converting into a different share class or not

American Funds Money Market Fund -- Page 33
<PAGE>

converting. In making its decision, the board of trustees will consider, among
other things, the effect of any such amendment on shareholders.

FREQUENT TRADING OF FUND SHARES -- As noted in the prospectus, certain
redemptions of shares in American Funds (other than the money market funds,
including this fund) may trigger a purchase block lasting 30 calendar days under
the fund's "purchase blocking policy." Under this policy, systematic redemptions
will not trigger a purchase block and systematic purchases will not be
prevented. For purposes of this policy, systematic redemptions include, for
example, regular periodic automatic redemptions and statement of intention
escrow share redemptions. Systematic purchases include, for example, regular
periodic automatic purchases and automatic reinvestments of dividends and
capital gain distributions.

OTHER POTENTIALLY ABUSIVE ACTIVITY -- In addition to implementing purchase
blocks, American Funds Service Company will monitor for other types of activity
that could potentially be harmful to the American Funds - for example,
short-term trading activity in multiple funds. When identified, American Funds
Service Company will request that the shareholder discontinue the activity. If
the activity continues, American Funds Service Company will freeze the
shareholder account to prevent all activity other than redemptions of fund
shares.

MOVING BETWEEN SHARE CLASSES

If you wish to "move" your investment between share classes (within the
same fund or between different funds), we generally will process your
request as an exchange of the shares you currently hold for shares in the
new class or fund. Below is more information about how sales charges are
handled for various scenarios.

EXCHANGING CLASS B SHARES FOR CLASS A SHARES -- If you exchange Class B
shares for Class A shares during the contingent deferred sales charge
period you are responsible for paying any applicable deferred sales charges
attributable to those Class B shares, but you will not be required to pay a
Class A sales charge. If, however, you exchange your Class B shares for
Class A shares after the contingent deferred sales charge period, you are
responsible for paying any applicable Class A sales charges.

EXCHANGING CLASS C SHARES FOR CLASS A SHARES -- If you exchange Class C
shares for Class A shares, you are still responsible for paying any Class C
contingent deferred sales charges and applicable Class A sales charges.

EXCHANGING CLASS C SHARES FOR CLASS F SHARES -- If you are part of a
qualified fee-based program and you wish to exchange your Class C shares
for Class F shares to be held in the program, you are still responsible for
paying any applicable Class C contingent deferred sales charges.

EXCHANGING CLASS F SHARES FOR CLASS A SHARES -- You can exchange Class F
shares held in a qualified fee-based program for Class A shares without
paying an initial Class A sales charge if all of the following requirements
are met: (a) you are leaving or have left the fee-based program, (b) you
have held the Class F shares in the program for at least one year, and (c)
you notify American Funds Service Company of your request. If you have
already redeemed your Class F shares, the foregoing requirements apply and
you must purchase Class A shares within 90 days after redeeming your Class
F shares to receive the Class A shares without paying an initial Class A
sales charge.

American Funds Money Market Fund -- Page 34
<PAGE>

EXCHANGING CLASS A SHARES FOR CLASS F SHARES -- If you are part of a
qualified fee-based program and you wish to exchange your Class A shares
for Class F shares to be held in the program, any Class A sales charges
(including contingent deferred sales charges) that you paid or are payable
will not be credited back to your account.

EXCHANGING CLASS A SHARES FOR CLASS R SHARES -- Provided it is eligible to
invest in Class R shares, a retirement plan currently invested in Class A
shares may exchange its shares for Class R shares. Any Class A sales
charges that the retirement plan previously paid will not be credited back
to the plan's account.

EXCHANGING CLASS F-1 SHARES FOR CLASS F-2 SHARES -- If you are part of a
qualified fee-based program that offers Class F-2 shares, you may exchange
your Class F-1 shares for Class F-2 shares to be held in the program.

MOVING BETWEEN OTHER SHARE CLASSES -- If you desire to move your investment
between share classes and the particular scenario is not described in this
statement of additional information, please contact American Funds Service
Company at 800/421-0180 for more information.

NON-REPORTABLE TRANSACTIONS -- Automatic conversions described in the
prospectus will be non-reportable for tax purposes. In addition, except in
the case of a movement between a 529 share class and a non-529 share class,
an exchange of shares from one share class of a fund to another share class
of the same fund will be treated as a non-reportable exchange for tax
purposes, provided that the exchange request is received in writing by
American Funds Service Company and processed as a single transaction.

CDSC WAIVERS FOR CLASS B AND C SHARES -- As noted in the prospectus, a
contingent deferred sales charge ("CDSC") may be waived for redemptions due to
death or post-purchase disability of a shareholder (this generally excludes
accounts registered in the names of trusts and other entities). In the case of
joint tenant accounts, if one joint tenant dies, a surviving joint tenant, at
the time he or she notifies the Transfer Agent of the other joint tenant's death
and removes the decedent's name from the account, may redeem shares from the
account without incurring a CDSC. Redemptions made after the Transfer Agent is
notified of the death of a joint tenant will be subject to a CDSC.

In addition, a CDSC may be waived for the following types of transactions, if
together they do not exceed 12% of the value of an "account" (defined below)
annually (the "12% limit"):

. Required minimum distributions taken from retirement accounts upon the
shareholder's attainment of age 70-1/2 (required minimum distributions
that continue to be taken by the beneficiary(ies) after the account
owner is deceased also qualify for a waiver).

. Redemptions through an automatic withdrawal plan ("AWP") (see
"Automatic withdrawals" under "Shareholder account services and
privileges" in this statement of additional information). For each AWP
payment, assets that are not subject to a CDSC, such as appreciation
on shares and shares acquired through reinvestment of dividends and/or
capital gain distributions, will be redeemed first and will count
toward the 12% limit. If there is an insufficient amount of assets not
subject to a CDSC to cover a particular AWP payment, shares subject to
the

American Funds Money Market Fund -- Page 35
<PAGE>

lowest CDSC will be redeemed next until the 12% limit is reached. Any
dividends and/or capital gain distributions taken in cash by a
shareholder who receives payments through an AWP will also count
toward the 12% limit. In the case of an AWP, the 12% limit is
calculated at the time an automatic redemption is first made, and is
recalculated at the time each additional automatic redemption is made.
Shareholders who establish an AWP should be aware that the amount of a
payment not subject to a CDSC may vary over time depending on
fluctuations in the value of their accounts. This privilege may be
revised or terminated at any time.

For purposes of this paragraph, "account" means:

. in the case of Class A shares, your investment in Class A shares of
all American Funds (investments representing direct purchases of
American Funds money market funds are excluded);

. in the case of Class B shares, your investment in Class B shares of
the particular fund from which you are making the redemption; and

. in the case of Class C shares, your investment in Class C shares of
the particular fund from which you are making the redemption.

CDSC waivers are allowed only in the cases listed here and in the prospectus.
For example, CDSC waivers will not be allowed on redemptions of Class 529-B and
529-C shares due to termination of CollegeAmerica; a determination by the
Internal Revenue Service that CollegeAmerica does not qualify as a qualified
tuition program under the Code; proposal or enactment of law that eliminates or
limits the tax-favored status of CollegeAmerica; or elimination of the fund by
the Virginia College Savings Plan as an option for additional investment within
CollegeAmerica.

SELLING SHARES

The methods for selling (redeeming) shares are described more fully in the
prospectus. If you wish to sell your shares by contacting American Funds Service
Company directly, any such request must be signed by the registered
shareholders. To contact American Funds Service Company via overnight mail or
courier service, see "Purchase and exchange of shares."

A signature guarantee may be required for certain redemptions. In such an event,
your signature may be guaranteed by a domestic stock exchange or the Financial
Industry Regulatory Authority, bank, savings association or credit union that is
an eligible guarantor institution. The Transfer Agent reserves the right to
require a signature guarantee on any redemptions.

Additional documentation may be required for sales of shares held in corporate,
partnership or fiduciary accounts. You must include with your written request
any shares you wish to sell that are in certificate form.

If you sell Class A, B or C shares and request a specific dollar amount to be
sold, we will sell sufficient shares so that the sale proceeds, after deducting
any applicable CDSC, equals the dollar amount requested.

Redemption proceeds will not be mailed until sufficient time has passed to
provide reasonable assurance that checks or drafts (including certified or
cashier's checks) for shares purchased

American Funds Money Market Fund -- Page 36
<PAGE>

have cleared (which may take up to 10 business days from the purchase date).
Except for delays relating to clearance of checks for share purchases or in
extraordinary circumstances (and as permissible under the 1940 Act), sale
proceeds will be paid on or before the seventh day following receipt and
acceptance of an order. Interest will not accrue or be paid on amounts that
represent uncashed distribution or redemption checks.

You may request that redemption proceeds of $1,000 or more from money market
funds be wired to your bank by writing American Funds Service Company. A
signature guarantee is required on all requests to wire funds.

SHAREHOLDER ACCOUNT SERVICES AND PRIVILEGES

The following services and privileges are generally available to all
shareholders. However, certain services and privileges described in the
prospectus and this statement of additional information may not be available for
Class 529 shareholders or if your account is held with an investment dealer or
through an employer-sponsored retirement plan.

AUTOMATIC INVESTMENT PLAN -- An automatic investment plan enables you to make
monthly or quarterly investments in the American Funds through automatic debits
from your bank account. To set up a plan, you must fill out an account
application and specify the amount that you would like to invest and the date on
which you would like your investments to occur. The plan will begin within 30
days after your account application is received. Your bank account will be
debited on the day or a few days before your investment is made, depending on
the bank's capabilities. The Transfer Agent will then invest your money into the
fund you specified on or around the date you specified. If the date you
specified falls on a weekend or holiday, your money will be invested on the
following business day. However, if the following business day falls in the next
month, your money will be invested on the business day immediately preceding the
weekend or holiday. If your bank account cannot be debited due to insufficient
funds, a stop-payment or the closing of the account, the plan may be terminated
and the related investment reversed. You may change the amount of the investment
or discontinue the plan at any time by contacting the Transfer Agent.

AUTOMATIC REINVESTMENT -- Dividends and capital gain distributions are
reinvested in additional shares of the same class and fund at net asset value
unless you indicate otherwise on the account application. You also may elect to
have dividends and/or capital gain distributions paid in cash by informing the
fund, the Transfer Agent or your investment dealer. Dividends and capital gain
distributions paid to retirement plan shareholders or shareholders of the 529
share classes will be automatically reinvested.

If you have elected to receive dividends and/or capital gain distributions in
cash, and the postal or other delivery service is unable to deliver checks to
your address of record, or you do not respond to mailings from American Funds
Service Company with regard to uncashed distribution checks, your distribution
option may be automatically converted to having all dividends and other
distributions reinvested in additional shares.

CROSS-REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS -- For all share classes,
except the 529 classes of shares, you may cross-reinvest dividends and capital
gains (distributions) into other American Funds in the same share class at net
asset value, subject to the following conditions:

American Funds Money Market Fund -- Page 37
<PAGE>

(1) the aggregate value of your account(s) in the fund(s) paying distributions
equals or exceeds $5,000 (this is waived if the value of the account in the fund
receiving the distributions equals or exceeds that fund's minimum initial
investment requirement);

(2) if the value of the account of the fund receiving distributions is below
the minimum initial investment requirement, distributions must be automatically
reinvested; and

(3) if you discontinue the cross-reinvestment of distributions, the value of
the account of the fund receiving distributions must equal or exceed the minimum
initial investment requirement. If you do not meet this requirement within 90
days of notification, the fund has the right to automatically redeem the
account.

AUTOMATIC EXCHANGES -- For all share classes, you may automatically exchange
shares of the same class in amounts of $50 or more among any of the American
Funds on any day (or preceding business day if the day falls on a nonbusiness
day) of each month you designate.

AUTOMATIC WITHDRAWALS -- Depending on the type of account, for all share classes
except R shares, you may automatically withdraw shares from any of the American
Funds. You can make automatic withdrawals of $50 or more. You can designate the
day of each period for withdrawals and request that checks be sent to you or
someone else. Withdrawals may also be electronically deposited to your bank
account. The Transfer Agent will withdraw your money from the fund you specify
on or around the date you specify. If the date you specified falls on a weekend
or holiday, the redemption will take place on the previous business day.
However, if the previous business day falls in the preceding month, the
redemption will take place on the following business day after the weekend or
holiday. You should consult with your adviser or intermediary to determine if
your account is eligible for automatic withdrawals.

Withdrawal payments are not to be considered as dividends, yield or income.
Withdrawals of amounts exceeding reinvested dividends and distributions and
increases in share value would reduce the aggregate value of the shareholder's
account. The Transfer Agent arranges for the redemption by the fund of
sufficient shares, deposited by the shareholder with the Transfer Agent, to
provide the withdrawal payment specified.

Redemption proceeds from an automatic withdrawal plan are not eligible for
reinvestment without a sales charge.

ACCOUNT STATEMENTS -- Your account is opened in accordance with your
registration instructions. Transactions in the account, such as additional
investments, will be reflected on regular confirmation statements from the
Transfer Agent. Dividend and capital gain reinvestments, purchases through
automatic investment plans and certain retirement plans, as well as automatic
exchanges and withdrawals, will be confirmed at least quarterly.

AMERICAN FUNDSLINE AND AMERICANFUNDS.COM -- You may check your share balance,
the price of your shares or your most recent account transaction; redeem shares
(up to $75,000 per American Funds shareholder each day) from nonretirement plan
accounts; or exchange shares around the clock with American FundsLine or using
americanfunds.com. To use American FundsLine, call 800/325-3590 from a
TouchTone(TM) telephone. Redemptions and exchanges through American FundsLine
and americanfunds.com are subject to the conditions noted above and in
"Telephone and Internet purchases, redemptions and exchanges" below. You will
need your fund number (see the list of the American Funds under "General
information -- fund

American Funds Money Market Fund -- Page 38
<PAGE>

numbers"), personal identification number (generally the last four digits of
your Social Security number or other tax identification number associated with
your account) and account number.

Generally, all shareholders are automatically eligible to use these services.
However, if you are not currently authorized to do so, you may complete an
American FundsLink Authorization Form. Once you establish this privilege, you,
your financial adviser or any person with your account information may use these
services.

TELEPHONE AND INTERNET PURCHASES, REDEMPTIONS AND EXCHANGES -- By using the
telephone (including American FundsLine) or the Internet (including
americanfunds.com), or fax purchase, redemption and/or exchange options, you
agree to hold the fund, the Transfer Agent, any of its affiliates or mutual
funds managed by such affiliates, and each of their respective directors,
trustees, officers, employees and agents harmless from any losses, expenses,
costs or liabilities (including attorney fees) that may be incurred in
connection with the exercise of these privileges. Generally, all shareholders
are automatically eligible to use these services. However, you may elect to opt
out of these services by writing the Transfer Agent (you may also reinstate them
at any time by writing the Transfer Agent). If the Transfer Agent does not
employ reasonable procedures to confirm that the instructions received from any
person with appropriate account information are genuine, it and/or the fund may
be liable for losses due to unauthorized or fraudulent instructions. In the
event that shareholders are unable to reach the fund by telephone because of
technical difficulties, market conditions or a natural disaster, redemption and
exchange requests may be made in writing only.

CHECKWRITING -- You will be eligible for checkwriting privileges upon meeting
the fund's initial purchase minimum of $1,000, regardless if such minimum has
been waived to establish your account. You may write checks for $250 or more
against your Class A share account in the funds. If you request check writing
privileges, you will be provided with checks that you may use to draw against
your account. These checks may be made payable to anyone you designate and must
be signed by the authorized number of registered shareholders exactly as
indicated on your checking account signature card. When the checks you write are
presented to JPMorgan Chase Bank for payment, the bank will instruct the
Transfer Agent to withdraw the appropriate number of shares from your account
(provided payment for the shares has been collected). The bank's rules and
regulations governing such checking accounts include the right of the bank not
to honor checks in amounts exceeding the value of the account at the time the
check is presented for payment. Each month canceled checks will be returned to
you. Generally, you pay no fee for this check writing service; however,
reasonable service charges for "regular or frequent use" of this service may be
assessed in the future. This procedure enables you to continue earning daily
income dividends on your money until your checks actually clear.

REDEMPTION OF SHARES -- The fund's declaration of trust permits the fund to
direct the Transfer Agent to redeem the shares of any shareholder for their then
current net asset value per share if at such time the shareholder of record owns
shares having an aggregate net asset value of less than the minimum initial
investment amount required of new shareholders as set forth in the fund's
current registration statement under the 1940 Act, and subject to such further
terms and conditions as the board of trustees of the fund may from time to time
adopt.

While payment of redemptions normally will be in cash, the fund's declaration of
trust permits payment of the redemption price wholly or partly with portfolio
securities or other fund assets under conditions and circumstances determined by
the fund's board of trustees. For example,

American Funds Money Market Fund -- Page 39
<PAGE>

redemptions could be made in this manner if the board determined that making
payments wholly in cash over a particular period would be unfair and/or harmful
to other fund shareholders.

GENERAL INFORMATION

CUSTODIAN OF ASSETS -- Securities and cash owned by the fund, including proceeds
from the sale of shares of the fund and of securities in the fund's portfolio,
are held by JPMorgan Chase Bank, 270 Park Avenue, New York, NY 10017-2070, as
Custodian. If a fund holds securities of issuers outside the U.S., the Custodian
may hold these securities pursuant to subcustodial arrangements in banks outside
the U.S. or branches of U.S. banks outside the U.S.

TRANSFER AGENT -- American Funds Service Company, a wholly owned subsidiary of
the investment adviser, maintains the records of shareholder accounts, processes
purchases and redemptions of the fund's shares, acts as dividend and capital
gain distribution disbursing agent, and performs other related shareholder
service functions. The principal office of American Funds Service Company is
located at 6455 Irvine Center Drive, Irvine, CA 92618. American Funds Service
Company is also compensated for certain transfer agency services provided to all
other share classes from the administrative services fees paid to Capital
Research and Management Company and from the relevant share class, as described
under "Administrative services agreement."

In the case of certain shareholder accounts, third parties who may be
unaffiliated with the investment adviser provide transfer agency and shareholder
services in place of American Funds Service Company. These services are rendered
under agreements with American Funds Service Company or its affiliates and the
third parties receive compensation according to such agreements. Compensation
for transfer agency and shareholder services, whether paid to American Funds
Service Company or such third parties, is ultimately paid from fund assets and
is reflected in the expenses of the fund as disclosed in the prospectus.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM -- PricewaterhouseCoopers LLP, 350
South Grand Avenue, Los Angeles, CA 90071, serves as the fund's independent
registered public accounting firm, providing audit services, preparation of tax
returns and review of certain documents to be filed with the Securities and
Exchange Commission. The financial statements included in this statement of
additional information have been audited by PricewaterhouseCoopers LLP, an
independent registered public accounting firm, as stated in their report
appearing herein. Such financial statements have been so included in reliance
upon the report of such firm given upon their authority as experts in accounting
and auditing. The selection of the fund's independent registered public
accounting firm is reviewed and determined annually by the board of trustees.

INDEPENDENT LEGAL COUNSEL -- Paul, Hastings, Janofsky & Walker LLP, 515 South
Flower Street, Los Angeles, CA 90071, serves as independent legal counsel
("counsel") for the fund and for independent trustees in their capacities as
such. A determination with respect to the independence of the fund's counsel
will be made at least annually by the independent trustees of the fund, as
prescribed by the 1940 Act and related rules.

PROSPECTUSES, REPORTS TO SHAREHOLDERS AND PROXY STATEMENTS -- The fund's fiscal
year ends on September 30. Shareholders are provided updated prospectuses
annually and at least semiannually with reports showing the fund's investment
portfolio or summary investment portfolio, financial statements and other
information. The fund's annual financial statements are

American Funds Money Market Fund -- Page 40
<PAGE>

audited by the fund's independent registered public accounting firm,
PricewaterhouseCoopers LLP. In addition, shareholders may also receive proxy
statements for the fund. In an effort to reduce the volume of mail shareholders
receive from the fund when a household owns more than one account, the Transfer
Agent has taken steps to eliminate duplicate mailings of prospectuses,
shareholder reports and proxy statements. To receive additional copies of a
prospectus, report or proxy statement, shareholders should contact the Transfer
Agent.

Shareholders may also elect to receive updated prospectuses, annual reports and
semi-annual reports electronically by signing up for electronic delivery on our
website, americanfunds.com. Upon electing the electronic delivery of updated
prospectuses and other reports, a shareholder will no longer automatically
receive such documents in paper form by mail. A shareholder who elects
electronic delivery is able to cancel this service at any time and return to
receiving updated prospectuses and other reports in paper form by mail.

Prospectuses, annual reports and semi-annual reports that are mailed to
shareholders by the American Funds organization are printed with ink containing
soy and/or vegetable oil on paper containing recycled fibers.

CODES OF ETHICS -- The fund and Capital Research and Management Company and its
affiliated companies, including the fund's Principal Underwriter, have adopted
codes of ethics that allow for personal investments, including securities in
which the fund may invest from time to time. These codes include a ban on
acquisitions of securities pursuant to an initial public offering; restrictions
on acquisitions of private placement securities; preclearance and reporting
requirements; review of duplicate confirmation statements; annual
recertification of compliance with codes of ethics; blackout periods on personal
investing for certain investment personnel; ban on short-term trading profits
for investment personnel; limitations on service as a director of publicly
traded companies; and disclosure of personal securities transactions.

LEGAL PROCEEDINGS -- On February 16, 2005, the NASD (now the Financial Industry
Regulatory Authority, or FINRA) filed an administrative complaint against the
Principal Underwriter. The complaint alleges violations of certain NASD rules by
the Principal Underwriter with respect to the selection of broker-dealer firms
that buy and sell securities for mutual fund investment portfolios. The
complaint seeks sanctions, restitution and disgorgement. On August 30, 2006, a
FINRA Hearing Panel ruled against the Principal Underwriter and imposed a $5
million fine. On April 30, 2008, FINRA's National Adjudicatory Council affirmed
the decision by FINRA's Hearing Panel. The Principal Underwriter has appealed
this decision to the Securities and Exchange Commission.

The investment adviser and Principal Underwriter believe that the likelihood
that this matter could have a material adverse effect on the fund or on the
ability of the investment adviser or Principal Underwriter to perform their
contracts with the fund is remote. In addition, class action lawsuits have been
filed in the U.S. District Court, Central District of California, relating to
this and other matters. The investment adviser believes that these suits are
without merit and will defend itself vigorously.

APPENDIX

DESCRIPTION OF COMMERCIAL PAPER RATINGS

MOODY'S
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

P-1
Issuers (or supporting institutions) rated Prime-1 have a superior ability to
repay short-term debt obligations.

P-2
Issuers (or supporting institutions) rated Prime-2 have a strong ability to
repay short-term debt obligations.

P-3
Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to
repay short-term obligations.

STANDARD & POOR'S
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

A-1
A short-term obligation rated A-1 is rated in the highest category by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is strong. Within this category, certain obligations are designated
with a plus sign (+). This indicates that the obligor's capacity to meet its
financial commitment on these obligations is extremely strong.

A-2
A short-term obligation rated A-2 is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rating categories. However, the obligor's capacity to meet its financial
commitment on the obligation is satisfactory.

A-3
A short-term obligation rated A-3 exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

FITCH
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

F1
Indicates the strongest capacity for timely payment of financial commitments
relative to other issuers or issues in the same country. Under their national
rating scale, this rating is assigned to the "best" credit risk relative to all
others in the same country and is normally assigned to all financial commitments
issued or guaranteed by the sovereign state. Where the credit risk is
particularly strong, a "+" is added to the assigned rating.

American Funds Money Market Fund -- Page 47
<PAGE>

F2
Indicates a satisfactory capacity for timely payment of financial commitments
relative to other issuers or issues in the same country. However, the margin of
safety is not as great as in the case of the higher ratings.

F3
Indicates an adequate capacity for timely payment of financial commitments
relative to other issuers or issues in the same country. However, such capacity
is more susceptible to near-term adverse changes than for financial commitments
in higher rated categories.

DBRS
COMMERCIAL PAPER RATINGS (HIGHEST THREE RATINGS)

R-1 (HIGH)
Short-term debt rated R-1 (high) is of the highest credit quality, and indicates
an entity possessing unquestioned ability to repay current liabilities as they
fall due. Entities rated in this category normally maintain strong liquidity
positions, conservative debt levels, and profitability that is both stable and
above average. Companies achieving an R-1 (high) rating are normally leaders in
structurally sound industry segments with proven track records, sustainable
positive future results, and no substantial qualifying negative factors. Given
the extremely tough definition DBRS has established for an R-1 (high), few
entities are strong enough to achieve this rating.

R-1 (MIDDLE)
Short-term debt rated R-1 (middle) is of superior credit quality and, in most
cases, ratings in this category differ from R-1 (high) credits by only a small
degree. Given the extremely tough definition DBRS has established for the R-1
(high) category, entities rated R-1 (middle) are also considered strong credits,
and typically exemplify above average strength in key areas of consideration for
the timely repayment of short-term liabilities.

R-1 (LOW)
Short-term debt rated R-1 (low) is of satisfactory credit quality. The overall
strength and outlook for key liquidity, debt, and profitability ratios is not
normally as favourable as with higher rating categories, but these
considerations are still respectable. Any qualifying negative factors that exist
are considered manageable, and the entity is normally of sufficient size to have
some influence in its industry.

Notes to statement of assets and liabilities

1.	Organization and significant accounting policies

Organization – American Funds Money Market Fund (the “fund”) was organized on February 4, 2009 as a Delaware statutory trust. To date, the fund has had no transactions other than those relating to organization matters and the sale of 100,000 shares of Class A capital stock to Capital Research and Management Company (“CRMC”), the fund’s investment adviser. The fund’s fiscal year ends on September 30. The fund will, upon declaration of effectiveness by the Securities and Exchange Commission (“SEC”), be registered under the Investment Company Act of 1940 (the “1940 Act”), as an open-end, diversified management investment company. The fund seeks to provide income on cash reserves, while preserving capital and maintaining liquidity.

Upon declaration of effectiveness by the SEC, the fund will offer 16 share classes consisting of five retail share classes, five 529 college savings plan share classes and six retirement plan share classes. The 529 college savings plan share classes (529-A, 529-B, 529-C, 529-E and 529-F-1) can be used to save for college education. The six retirement plan share classes (R-1, R-2, R-3, R-4, R-5 and R-6) are sold without any sales charges and do not carry any conversion rights. The fund’s share classes are described below:

Share class	Initial sales charge	Contingent deferred sales charge upon redemption	Conversion feature
Classes A and 529-A	None	None	None
Classes B and 529-B	None	Declines from 5% to 0% for redemptions within six years of purchase	Classes B and 529-B convert to Classes A and 529-A, respectively, after eight years
Class C	None	1% for redemptions within one year of purchase	Class C converts to Class F-1 after 10 years
Class 529-C	None	1% for redemptions within one year of purchase	None
Class 529-E	None	None	None
Classes F-1, F-2, and 529-F-1	None	None	None
Classes R-1, R-2, R-3, R-4, R-5 and R-6	None	None	None

Holders of all share classes have equal pro rata rights to assets, dividends and liquidation proceeds. Each share class has identical voting rights, except for the exclusive right to vote on matters affecting only its class. Share classes have different fees and expenses ("class-specific fees and expenses"), primarily due to different arrangements for distribution, administrative and shareholder services. Differences in class-specific fees and expenses will result in differences in net investment income and, therefore, the payment of different per-share dividends by each class.

Significant accounting policies - The financial statements have been prepared to comply with accounting principles generally accepted in the United States of America. These principles require management to make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from those estimates.

2.	Fees and transactions with related parties

The fund has entered into an Investment Advisory and Service Agreement with CRMC, a Principal Underwriting Agreement with American Funds Distributors, Inc.® ("AFD"), and a Shareholder Services Agreement with American Funds Service Company ® ("AFS"), each of which will be effective May 1, 2009. CRMC is the parent company of AFD and AFS.

Investment advisory services –The Investment Advisory and Service Agreement with CRMC provides for monthly fees accrued daily. These fees are based on a declining series of annual rates beginning with 0.295% on the first $1 billion of daily net assets and decreasing to 0.256% on such assets in excess of $34 billion.

Distribution services – The fund has adopted plans of distribution for all share classes, except Classes F-2, R-5 and R-6, pursuant to rule 12b-1 under the 1940 Act. Under the plan, the board of trustees approves certain categories of expenses that are used to finance activities primarily intended to sell fund shares and service existing shareholder accounts. The plans provide for payments, based on an annualized percentage of average daily net assets, ranging from 0.15% to 1.00% as noted below. In some cases, the board of trustees has limited the amounts that may be paid to less than the maximum allowed by the plans. All share classes except Classes F-2, R-5 and R-6 may use a portion (0.15% for Class A, B, 529-A and 529-B shares and 0.25% for all other classes) 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 to provide certain shareholder services. The remaining amounts available to be paid under each plan are paid to dealers to compensate them for their sales activities. The fund may suspend 12b-1 payments under agreements between its principal underwriter and intermediaries and other entities that sell fund shares. The fund is currently suspending 12b-1 payments in this low interest rate environment.

Share class	Currently approved limits	Plan limits
Class A	0.15%	0.15%
Class 529-A	0.15	0.50
Classes B and 529-B	0.90	0.90
Classes C, 529-C and R-1	1.00	1.00
Class R-2	0.75	1.00
Classes 529-E and R-3	0.50	0.75
Classes F-1, 529-F-1 and R-4	0.25	0.50

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 up to 0.15% (0.10% for Class R-5 and 0.05% for Class R-6) 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. Each 529 share class is subject to an additional administrative services fee payable to the Commonwealth of Virginia for the maintenance of the 529 college savings plan. The quarterly fee is based on a declining series of annual rates beginning with 0.10% on the first $30 billion of the net assets invested in Class 529 shares of the American Funds and decreasing to 0.06% on such assets between $120 billion and $150 billion. The fee for any given calendar quarter is accrued and calculated on the basis of the average net assets of Class 529 shares of the American Funds for the last month of the prior calendar quarter. Although these amounts will be included with administrative services fees, the Commonwealth of Virginia is not considered a related party.

Trustees’ deferred compensation – The board of trustees has adopted a deferred compensation plan. Trustees who are unaffiliated with CRMC 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. These amounts represent general, unsecured liabilities of the fund and vary according to the total return of the fund.

Affiliated officers and trustees - Officers and certain trustees of the fund are or may be considered to be affiliated with CRMC, AFS and AFD. No affiliated officers or trustees will receive any compensation directly from the fund.

3.	Federal income taxation and distributions

It is the fund’s policy to comply in its initial year and thereafter with the requirements under Subchapter M of the Internal Revenue Code applicable to mutual funds and to distribute substantially all of its net taxable income and net capital gains each year.

4.	Offering and organizational expenses

CRMC has agreed to bear all organizational expenses for the fund, including administration, legal, state registration, and printing fees.

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 expense
reimbursements.

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

Principal investment strategies

The fund invests substantially in U.S. Treasury securities and other securities
backed by the full faith and credit of the United States government, as well as
securities issued by U.S. federal agencies. The fund may also invest in other
high-quality money market instruments.

The fund may invest in securities issued by entities domiciled outside of the
U.S. and securities with credit and liquidity support features provided by
entities domiciled outside of the U.S. The fund may also invest in securities of
U.S. issuers with substantial operations outside the United States.

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 provide current income while
preserving capital and maintaining liquidity. The investment adviser believes
that an important way to accomplish this is by analyzing various factors,
including the credit strength of the issuer, prices of similar securities issued
by comparable issuers, current and anticipated changes in interest rates,
general market conditions and other factors pertinent to the particular security
being evaluated.

The fund has entered into an Agreement and Plan of Reorganization and
Liquidation with The Cash Management Trust of America and The U.S. Treasury
Money Fund of America, or the target funds, to merge the target funds into the
fund in exchange for shares of beneficial interest of the fund, subject to the
approval of the target funds' shareholders. As of the date of this prospectus,
the target funds had a combined total asset value of approximately $34 billion.
These assets may be more or less as of the date of the completion of the
mergers, which the fund expects to be in summer 2009. If the mergers are
completed and the target funds are participants of the U.S. Treasury's Temporary
Guarantee Program for Money Market Funds at such time, shareholders of the
target funds that were insured under the program as of the completion of the
mergers will be covered by the program to the same extent in the fund. Under the
program, the Treasury is guaranteeing investors of any participating fund that
in the event the fund is liquidated they will receive $1.00 for the lesser of
(i) each share of the fund held in an account as of the close of business on
September 19, 2008 and (ii) each share of the fund held in that account on the
date the fund's net asset value falls below $0.9950. The guarantee does not
cover shares of a fund purchased after the close of business on September 19,
2008, to the extent the number of shares held in a particular account exceeds
the number of shares held in that account on September 19, 2008. The program is
currently operational until April 30, 2009, but may be extended by the Secretary
of the Treasury through September 19, 2009. The duration and terms of any such
extension have not been determined, and there is no assurance that either of the
target funds will participate in any such extension.

Principal risks

Although the fund seeks to preserve the value of your investment at $1.00 per
share, it is possible to lose money by investing in the fund.

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.

The value and liquidity of the securities held by the fund may be affected by
changing interest rates and by changes in credit ratings of the securities. For
example, the values of these securities may decline when interest rates rise and
increase when interest rates fall.

Some of the securities held by the fund may have credit and liquidity
enhancements. Changes in the credit quality of the issuer or provider of these
enhancements could cause the fund to experience a loss and may affect its share
price.

Additionally, the securities held by the fund may be affected by unfavorable
political, economic or governmental developments that could affect the repayment
of principal or the payment of interest.

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 portfolios and business affairs of the fund. The total management
fees to be paid by the fund for the current fiscal year, as a percentage of
average net assets, appear in the Annual Fund Operating Expenses table under
"Fees and expenses of the fund." A more detailed description of the investment
advisory and service agreement between the fund and the investment adviser is
included in the fund's statement of additional information, and a discussion
regarding the basis for its approval by the fund's board of trustees will be
contained in the fund's annual report to shareholders.

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 will be available on the American
Funds website at americanfunds.com. To reach this information, access the fund's
detailed information page on the website. 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. This information is available on the website until new information for
the next 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.

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.

The American Funds (other than the money market funds, including this fund) have
adopted a "purchase blocking policy" under which any shareholder redeeming
shares having a value of $5,000 or more from a fund (other than the money market
funds, including this fund) will be precluded from investing in that 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
American Funds' 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/(R)/; 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.

Each fund reserves the right to waive the purchase blocking policy with respect
to specific shareholder accounts in those instances where American Funds Service
Company


                                       10

American Funds Money Market Fund / Prospectus


<PAGE>

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 funds. 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 FUNDS' SURVEILLANCE PROCEDURES AND PURCHASE BLOCKING POLICY,
ALL TRANSACTIONS IN FUND SHARES REMAIN SUBJECT TO THE RIGHT OF THE FUND AND
AMERICAN FUNDS DISTRIBUTORS' 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 seeks to preserve the net asset value of each share class at
$1.00. 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. The fund may also calculate its share price on
days the New York Stock Exchange is closed when deemed prudent to do so by the
fund's officers. 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, fair value procedures may be used if an issuer defaults and there
is no market for its securities. Use of these procedures is intended to result
in more appropriate net asset values.

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.


                                       12

American Funds Money Market Fund / Prospectus


<PAGE>


The valuation of the fund's portfolio securities and calculation of its net
asset value are based upon the penny-rounding method of pricing pursuant to
Securities and Exchange Commission regulations, which permit current net asset
value per share to be rounded to the nearest cent, provided the fund follows
certain maturity, credit quality and other guidelines under the Securities and
Exchange Commission regulations. The fund follows standard industry practice by
typically reflecting changes in its holdings of portfolio securities on the
first business day following a portfolio trade.

All securities with 60 days or less to maturity are amortized to maturity based
on their cost if acquired within 60 days of maturity, or if already held on the
60th day, based on the value determined on the 61st day. The maturities of
variable or floating rate instruments, with the right to resell them at an
agreed-upon price to the issuer or dealer, are deemed to be the time remaining
until the later of the next interest adjustment date or until they can be
resold.

Other securities with more than 60 days remaining to maturity are valued at
prices obtained from one or more pricing vendors selected by the investment
adviser, except that, if such prices are not available or if the investment
adviser has determined that such prices do not reflect current market value,
they are valued in good faith at the mean between bid and ask quotations that
are reasonably and timely available from one or more dealers in such securities.


If market prices or market quotations are not readily available or are
considered unreliable, securities are valued at fair value as determined in good
faith pursuant to procedures adopted by the board of trustees. The fair value of
all other assets is added to the value of securities to arrive at the total
assets.

Your shares will be purchased at the net asset value 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

Class A shares of the fund are sold without an initial sales charge. However, if
shares of the fund are exchanged for shares of an American Funds non-money
market fund, the sales charge applicable to the non-money market fund may apply.

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 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).

Rollovers from retirement plans to IRAs

Assets from retirement plans may be invested in Class A, B, 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 B,
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 trustees. The plans provide for payments, based on annualized percentages of
average daily net assets, of up to .15% for Class A shares, up to 1.00% for
Class R-1 shares, and up to 1.00%, .75% and .50% for Class R-2, R-3 and R-4
shares, respectively. For all share classes indicated above, a portion of these
expenses (up to .15% for Class A shares and .25% for Class R shares) 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 estimated 12b-1 fees paid by the fund, as a percentage of average net assets
for the current 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.

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 expense
reimbursements.

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

Principal investment strategies

The fund invests substantially in U.S. Treasury securities and other securities
backed by the full faith and credit of the United States government, as well as
securities issued by U.S. federal agencies. The fund may also invest in other
high-quality money market instruments.

The fund may invest in securities issued by entities domiciled outside of the
U.S. and securities with credit and liquidity support features provided by
entities domiciled outside of the U.S. The fund may also invest in securities of
U.S. issuers with substantial operations outside the United States.

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 provide current income while
preserving capital and maintaining liquidity. The investment adviser believes
that an important way to accomplish this is by analyzing various factors,
including the credit strength of the issuer, prices of similar securities issued
by comparable issuers, current and anticipated changes in interest rates,
general market conditions and other factors pertinent to the particular security
being evaluated.

The fund has entered into an Agreement and Plan of Reorganization and
Liquidation with The Cash Management Trust of America and The U.S. Treasury
Money Fund of America, or the target funds, to merge the target funds into the
fund in exchange for shares of beneficial interest of the fund, subject to the
approval of the target funds' shareholders. As of the date of this prospectus,
the target funds had a combined total asset value of approximately $34 billion.
These assets may be more or less as of the date of the completion of the
mergers, which the fund expects to be in summer 2009. If the mergers are
completed and the target funds are participants of the U.S. Treasury's Temporary
Guarantee Program for Money Market Funds at such time, shareholders of the
target funds that were insured under the program as of the completion of the
mergers will be covered by the program to the same extent in the fund. Under the
program, the Treasury is guaranteeing investors of any participating fund that
in the event the fund is liquidated they will receive $1.00 for the lesser of
(i) each share of the fund held in an account as of the close of business on
September 19, 2008 and (ii) each share of the fund held in that account on the
date the fund's net asset value falls below $0.9950. The guarantee does not
cover shares of a fund purchased after the close of business on September 19,
2008, to the extent the number of shares held in a particular account exceeds
the number of shares held in that account on September 19, 2008. The program is
currently operational until April 30, 2009, but may be extended by the Secretary
of the Treasury through September 19, 2009. The duration and terms of any such
extension have not been determined, and there is no assurance that either of the
target funds will participate in any such extension.

Principal risks

Although the fund seeks to preserve the value of your investment at $1.00 per
share, it is possible to lose money by investing in the fund.

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.

The value and liquidity of the securities held by the fund may be affected by
changing interest rates and by changes in credit ratings of the securities. For
example, the values of these securities may decline when interest rates rise and
increase when interest rates fall.

Some of the securities held by the fund may have credit and liquidity
enhancements. Changes in the credit quality of the issuer or provider of these
enhancements could cause the fund to experience a loss and may affect its share
price.

Additionally, the securities held by the fund may be affected by unfavorable
political, economic or governmental developments that could affect the repayment
of principal or the payment of interest.

investment divisions, Capital World Investors and Capital Research Global
Investors, and manages fixed-income assets through its Fixed Income division.

R shares by contacting any investment dealer (who may impose transaction charges
in addition to those described in this prospectus) authorized to sell the fund's
shares.

Class R shares generally are available only to 401(k) plans, 457 plans, 403(b)
plans, profit-sharing and money purchase pension plans, defined benefit plans
and nonqualified deferred compensation plans. Class R shares also are generally
available only to retirement plans where plan level or omnibus accounts are held
on the books of the fund.

Tax information

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

Financial intermediary compensation

If you purchase the fund through a broker-dealer or other financial intermediary
(such as a bank), the fund and its related companies may pay the intermediary
for the sale of fund shares and related services. These payments may influence
the broker-dealer or other intermediary and your salesperson to recommend the
fund over another investment. Ask your salesperson or visit your financial
intermediary's website for more information.

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 portfolios and business affairs of the fund. The total management
fees to be paid by the fund for the current fiscal year, as a percentage of
average net assets, appear in the Annual Fund Operating Expenses table under
"Fees and expenses of the fund." A more detailed description of the investment
advisory and service agreement between the fund and the investment adviser is
included in the fund's statement of additional information, and a discussion
regarding the basis for its approval by the fund's board of trustees will be
contained in the fund's annual report to shareholders.

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 will be available on the American
Funds website at americanfunds.com. To reach this information, access the fund's
detailed information page on the website. 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. This information is available on the website until new information for
the next 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.

CERTAIN PRIVILEGES AND/OR SERVICES DESCRIBED ON THE FOLLOWING PAGES OF THIS
PROSPECTUS AND IN THE STATEMENT OF ADDITIONAL INFORMATION MAY NOT BE AVAILABLE
TO YOU, DEPENDING ON YOUR INVESTMENT DEALER OR RETIREMENT PLAN RECORDKEEPER.

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.

The American Funds (other than the money market funds, including this fund) have
adopted a "purchase blocking policy" under which any shareholder redeeming
shares having a value of $5,000 or more from a fund (other than the money market
funds, including this fund) will be precluded from investing in that 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
American Funds' 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/(R)/; 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.

Each fund reserves the right to waive the purchase blocking policy with respect
to specific shareholder accounts in those instances where American Funds Service
Company


                                       10

American Funds Money Market Fund / Prospectus

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 funds. 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 FUNDS' SURVEILLANCE PROCEDURES AND PURCHASE BLOCKING POLICY,
ALL TRANSACTIONS IN FUND SHARES REMAIN SUBJECT TO THE RIGHT OF THE FUND AND
AMERICAN FUNDS DISTRIBUTORS' 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 seeks to preserve the net asset value of each share class at
$1.00. 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. The fund may also calculate its share price on
days the New York Stock Exchange is closed when deemed prudent to do so by the
fund's officers. 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, fair value procedures may be used if an issuer defaults and there
is no market for its securities. Use of these procedures is intended to result
in more appropriate net asset values.

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.


                                       12

American Funds Money Market Fund / Prospectus


<PAGE>


The valuation of the fund's portfolio securities and calculation of its net
asset value are based upon the penny-rounding method of pricing pursuant to
Securities and Exchange Commission regulations, which permit current net asset
value per share to be rounded to the nearest cent, provided the fund follows
certain maturity, credit quality and other guidelines under the Securities and
Exchange Commission regulations. The fund follows standard industry practice by
typically reflecting changes in its holdings of portfolio securities on the
first business day following a portfolio trade.

All securities with 60 days or less to maturity are amortized to maturity based
on their cost if acquired within 60 days of maturity, or if already held on the
60th day, based on the value determined on the 61st day. The maturities of
variable or floating rate instruments, with the right to resell them at an
agreed-upon price to the issuer or dealer, are deemed to be the time remaining
until the later of the next interest adjustment date or until they can be
resold.

Other securities with more than 60 days remaining to maturity are valued at
prices obtained from one or more pricing vendors selected by the investment
adviser, except that, if such prices are not available or if the investment
adviser has determined that such prices do not reflect current market value,
they are valued in good faith at the mean between bid and ask quotations that
are reasonably and timely available from one or more dealers in such securities.


If market prices or market quotations are not readily available or are
considered unreliable, securities are valued at fair value as determined in good
faith pursuant to procedures adopted by the board of trustees. The fair value of
all other assets is added to the value of securities to arrive at the total
assets.

Your shares will be purchased at the net asset value 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

Class A shares of the fund are sold without an initial sales charge. However, if
shares of the fund are exchanged for shares of an American Funds non-money
market fund, the sales charge applicable to the non-money market fund may apply.

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 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).

Rollovers from retirement plans to IRAs

Assets from retirement plans may be invested in Class A, B, 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 B,
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 trustees. The plans provide for payments, based on annualized percentages of
average daily net assets, of up to .15% for Class A shares, up to 1.00% for
Class R-1 shares, and up to 1.00%, .75% and .50% for Class R-2, R-3 and R-4
shares, respectively. For all share classes indicated above, a portion of these
expenses (up to .15% for Class A shares and .25% for Class R shares) 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 estimated 12b-1 fees paid by the fund, as a percentage of average net assets
for the current 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.

reinvested.

TAXES ON DIVIDENDS

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

Item 25. Indemnification

The Registrant is a joint-insured under Investment Adviser/Mutual Fund Errors and Omissions Policies, which insure its officers and directors against certain liabilities. However, in no event will Registrant maintain insurance to indemnify any such person for any act for which Registrant itself is not permitted to indemnify the individual.

Section 8 of the Registrant's Declaration of Trust as well as the indemnification agreements that the Registrant has entered into with each of its trustees who is not an “interested person” of the Registrant (as defined under the Investment Company Act of 1940, as amended), provide in effect that the Registrant will indemnify its officers and trustees against any liability or expenses actually and reasonably incurred by such person in any proceeding arising out of or in connection with his or her service to the Registrant, to the fullest extent permitted by applicable law, subject to certain conditions. In accordance with Section 17(h) and 17(i) of the Investment Company Act of 1940, as amended, and their respective terms, these provisions do not protect any person against any liability to the Registrant or its shareholders to which such person would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Registrant will comply with the indemnification requirements contained in the Investment Company Act of 1940, as amended, and Release Nos. 7221 (June 9, 1972) and 11330 (September 4, 1980).
