   KEY FACTS    
 
 
WHO MAY WANT TO INVEST
The fund is generally intended for investors in tax-saving retirement plans
such as defined contribution plans, 403(b) accounts, defined benefit plans
and 457 plans.
The fund is designed for        investors who would like to earn current
income while preserving the value of their investment.
The rate of income will vary from day to day, generally reflecting
short-term interest rates.
The fund is managed to keep its share price stable at $1.00 and offers an
added measure of safety with its focus on U.S. Government securities.
The fund does not constitute a balanced investment plan. However, because
it emphasizes stability, it could be well-suited for a portion of your
savings.

[B] FROM MONTH END CLOSEST TO COMMENCEMENT OF OPERATIONS.

   5.53    % and its effective yield was    5.69    %.
EXPLANATION OF TERMS
TOTAL RETURN is the change in value of an investment in the fund over a
given period, assuming reinvestment of any dividends and capital gains. A
CUMULATIVE TOTAL RETURN reflects actual performance over a stated period of
time. An AVERAGE ANNUAL TOTAL RETURN is a hypothetical rate of return that,
if achieved annually, would have produced the same cumulative total return
if performance had been constant over the entire period. Average annual
total returns smooth out variations in performance; they are not the same
as actual year-by-year results.
YIELD refers to the income generated by an investment in the fund over a
given period of time, expressed as an annual percentage rate. When a yield
assumes that income earned is reinvested, it is called an EFFECTIVE YIELD.
SEVEN-DAY YIELD illustrates the income earned by an investment in the fund

   THE FUND IN DETAIL    
 
 
CHARTER
RETIREMENT GOVERNMENT MONEY MARKET IS A MUTUAL FUND: an investment that
pools shareholders' money and invests it toward a specified goal. The fund
is a diversified fund of Fidelity Money Market Trust, an open-end
management investment company organized as a Delaware business trust on
December 29, 1994.
THE FUND IS GOVERNED BY A BOARD OF TRUSTEES which is responsible for
protecting the interests of shareholders. The trustees are experienced
executives who meet throughout the year to oversee the fund's activities,
review contractual arrangements with companies that provide services to the
fund, and review the fund's performance. The majority of trustees are not
otherwise affiliated with Fidelity.
THE FUND MAY HOLD SPECIAL MEETINGS AND MAIL PROXY MATERIALS. These meetings
may be called to elect or remove trustees, change fundamental policies,
approve a management contract, or for other purposes. Shareholders not
attending these meetings are encouraged to vote by proxy. The transfer
agent will mail proxy materials in advance, including a voting card and
information about the proposals to be voted on. The number of votes you are
entitled to is based upon the dollar value of your investment.
FMR AND ITS AFFILIATES
Fidelity Investments is one of the largest investment management
organizations in the United States and has its principal business address
at 82 Devonshire Street, Boston, Massachusetts 02109. It includes a number
of different subsidiaries and divisions which provide a variety of
financial services and products. The fund employs various Fidelity
companies to perform activities required for its operation.
The fund is managed by FMR, which handles the fund's business affairs. FMR
Texas Inc. (FMR Texas), located in Irving, Texas, has primary
responsibility for providing investment management services.
As of August 31, 1995, FMR advised funds having approximately 22 million
shareholder accounts with a total value of more than $328 billion.
Fidelity investment personnel may invest in securities for their own
account pursuant to a code of ethics that establishes procedures for
personal investing and restricts certain transactions.
Fidelity Distributors Corporation (FDC) distributes and markets Fidelity's
funds and services. Fidelity Investments Institutional Operations Company
(FIIOC) performs transfer agent servicing functions for the fund.
FMR Corp. is the ultimate parent company of FMR and FMR Texas. Members of
the Edward C. Johnson 3d family are the predominant owners of a class of
shares of common stock representing approximately 49% of the voting power
of FMR Corp. Under the Investment Company Act of 1940 (the 1940 Act),
control of a company is presumed where one individual or group of
individuals owns more than 25% of the voting stock of that company;
therefore, the Johnson family may be deemed under the 1940 Act to form a
controlling group with respect to FMR Corp.
To carry out the fund's transactions, FMR may use its broker-dealer
affiliates and other firms that sell fund shares, provided that the fund
receives services and commission rates comparable to those of other
broker-dealers.
INVESTMENT PRINCIPLES AND RISKS
The fund invests only in obligations issued or guaranteed as to principal
and interest by the U.S. Government or by any of its agencies or
instrumentalities, and in repurchase agreements secured by these
obligations.
When you sell your shares, they should be worth the same amount as when you
bought them. Of course, there is no guarantee that the fund will maintain a
stable $1.00 share price. The fund follows industry-standard guidelines on
the quality and maturity of its investments, which are designed to help
maintain a stable $1.00 share price. The fund will purchase only
high-quality securities that FMR believes present minimal credit risks and
will observe maturity restrictions on securities it buys. In general,
securities with longer maturities are more vulnerable to price changes,
although they may provide higher yields. It is possible that a major change
in interest rates or a default on the fund's investments could cause its
share price (and the value of your investment) to change.
The fund earns income at current money market rates. It stresses   
    preservation of capital,        liquidity,    and income     and does
not seek the higher yields or capital appreciation that more aggressive
investments may provide. The fund's yield will vary from day to day and
generally reflects current short-term interest rates and other market
conditions. It is important to note that neither the fund nor its yield is
guaranteed by the U.S. Government.
SECURITIES AND INVESTMENT PRACTICES
The following pages contain more detailed information about types of
instruments in which the fund may invest, strategies FMR may employ in
pursuit of the fund's investment objective, and a summary of related risks.
Any restrictions listed supplement those discussed earlier in this section.
A complete listing of the fund's limitations and more detailed information
about the fund's investments are contained in the fund's SAI. Policies and
limitations are considered at the time of purchase; the sale of instruments
is not required in the event of a subsequent change in circumstances.
FMR may not buy all of these instruments or use all of these techniques
unless it believes that they are consistent with the fund's investment
objective and policies and that doing so will help the fund achieve its
goal. Current holdings and recent investment strategies are described in
the fund's financial reports, which are sent to shareholders twice a year.

the appropriate number listed on page .
U.S. GOVERNMENT MONEY MARKET SECURITIES are short-term debt obligations
issued or guaranteed by the U.S. Treasury or by an agency or
instrumentality of the U.S. Government. Not all U.S. Government securities
are backed by the full faith and credit of the United States. For example,
securities issued by the Federal Farm Credit Bank or by the Federal
National Mortgage Association are supported by the instrumentality's right
to borrow money from the U.S. Treasury under certain circumstances.
However, securities issued by the Financing Corporation are supported only
by the credit of the entity that issued them.
VARIABLE AND FLOATING RATE SECURITIES have interest rates that are
periodically adjusted either at specific intervals or whenever a benchmark
rate changes. These interest rate adjustments are designed to help
stabilize the security's price.
STRIPPED SECURITIES are the separate income or principal components of a
debt security. Their risks are similar to those of other money market
securities, although they may be more volatile.
REPURCHASE AGREEMENTS. In a repurchase agreement, the fund buys a security
at one price and simultaneously agrees to sell it back at a higher price.
Delays or losses could result if the other party to the agreement defaults
or becomes insolvent.
REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the fund
temporarily transfers possession of a portfolio instrument to another party
in return for cash. This could increase the risk of fluctuation in the
fund's yield or in the market value of its assets.
PUT FEATURES entitle the holder to put (sell back) a security to the issuer
or a financial intermediary. In exchange for this benefit, the fund may pay
periodic fees or accept a lower interest rate.
   ILLIQUID AND RESTRICTED SECURITIES. Some investments may be determined
by FMR, under the supervision of the Board of Trustees, to be illiquid,
which means that they may be difficult to sell promptly at an acceptable
price. The sale of some illiquid securities, and some other securities, may
be subject to legal restrictions. Difficulty in selling securities may
result in a loss or may be costly to the fund.    
RESTRICTION: The fund may not purchase a security if, as a result, more
than 10% of its net assets would be invested in illiquid securities. 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS are trading practices in
which payment and delivery for the securities take place at a future date.
The market value of a security could change during this period, which could
affect the market value of the fund's assets. 
BORROWING. The fund may borrow from banks or from other funds advised by
FMR, or through reverse repurchase agreements, and may make additional
investments while borrowings are outstanding.
RESTRICTION: The fund may borrow only for temporary or emergency purposes,
or engage in reverse repurchase agreements, but not in an amount exceeding
331/3% of its total assets.
FUNDAMENTAL INVESTMENT POLICIES AND RESTRICTIONS
Some of the policies and restrictions discussed on the preceding pages are
fundamental, that is, subject to change only by shareholder approval. The
following paragraphs restate all those that are fundamental. All policies
stated throughout this prospectus, other than those identified in the
following paragraphs, can be changed without shareholder approval. 
The fund seeks to obtain as high a level of current income as is consistent
with the preservation of capital and liquidity.
The fund may borrow only for temporary or emergency purposes, or engage in
reverse repurchase agreements, but not in an amount exceeding 331/3% of its
total assets.
BREAKDOWN OF EXPENSES
Like all mutual funds, the fund pays fees related to its daily operations.
Expenses paid out of the fund's assets are reflected in its share price or
dividends; they are neither billed directly to shareholders nor deducted
from shareholder accounts.
FMR may, from time to time, agree to reimburse the fund for management fees
above a specified limit. Reimbursement arrangements, which may be
terminated at any time without notice, can decrease the fund's expenses and
boost its performance.
MANAGEMENT FEE
The management fee is calculated and paid to FMR every month. FMR pays all
of the expenses of the fund with limited exceptions. The annual management
fee is 0.42% of the fund's average net assets.
FMR HAS A SUB-ADVISORY AGREEMENT with FMR Texas, which has primary
responsibility for providing investment management for the fund, while FMR
retains responsibility for providing the fund with other management
services. FMR pays FMR Texas 50% of its management fee (before expense
reimbursements) for these services. FMR paid FMR Texas    0.21    % of the
fund's average net assets for fiscal 1995.
OTHER EXPENSES
FIIOC performs transfer agency, dividend disbursing and shareholder
servicing functions for the fund. Fidelity Service Co. (FSC) calculates the
net asset value (NAV) and dividends for the fund and maintains the fund's
general accounting records.
These expenses are paid by FMR pursuant to its management contract.
The fund has adopted a DISTRIBUTION AND SERVICE PLAN. This plan recognizes
that FMR may use its resources, including management fees, to pay expenses
associated with the sale of fund shares. This may include    reimbursing
FDC for     payments to third parties, such as banks or broker-dealers,
that provide shareholder support services or engage in the sale of the
fund's shares. The Board of Trustees has not authorized such payments.
The fund also pays other expenses, such as brokerage fees and commissions,
taxes, and the compensation of trustees who are not affiliated with
Fidelity.

INVESTOR SERVICES
Fidelity provides a variety of services to help you manage your account.
INFORMATION SERVICES
STATEMENTS AND REPORTS that the transfer agent sends to you include the
following:
(small solid bullet) Confirmation statements (after every transaction,
except a reinvestment, that affects your account balance or your account
registration)
(small solid bullet) Account statements (quarterly)
(small solid bullet) Financial reports (every six months)
To reduce expenses, only one copy of most financial reports will be mailed,
even if you have more than one account in the fund. Call Fidelity Client
Services at the appropriate number listed on page  if you need additional
copies of financial reports or historical account information.
SUB-ACCOUNTING AND SPECIAL SERVICES. Special processing has been arranged
with FIIOC for institutions that wish to open multiple accounts (a master
account and sub-accounts). You may be required to enter into a separate
agreement with FIIOC. Charges for these services, if any, will be
determined based on the level of services to be rendered.
   SHAREHOLDER AND ACCOUNT POLICIES    
 
 
DIVIDENDS, CAPITAL GAINS, AND TAXES
The fund distributes substantially all of its net investment income and
capital gains, if any, to shareholders each year. Income dividends are
declared daily and paid monthly.
Income dividends declared are accrued daily throughout the month and are
   normally     distributed on the first business day of the following
month. Based on prior approval of the fund, dividends relating to shares
redeemed during the month can be distributed on the day of redemption. The
fund reserves the right to limit this service. Shareholders may elect to
receive dividend distributions in cash.
DISTRIBUTION OPTIONS
When you open an account, specify on your account application how you want
to receive your distributions. The fund offers    two     options:
1. REINVESTMENT OPTION. Your    divdiend and     capital gain
distributions, if any, will be automatically reinvested in additional
shares of the fund. If you do not indicate a choice on your application,
you will be assigned this option.
   2    . CASH OPTION. You will be sent a check for your dividend and
capital gain distributions, if any.
For retirement accounts, all distributions are automatically reinvested.
When you are over 59 1/2 years old, you can receive distributions in cash.
Dividends will be reinvested at the fund's NAV on the last day of the
month. Capital gain distributions, if any, will be reinvested at the NAV as
of the record date of the distribution. The mailing of distribution checks
will begin within seven days.
TAXES
As with any investment, you should consider how your investment in the fund
will be taxed. If your account is not a tax-deferred retirement account,
you should be aware of these tax implications.
TAXES ON DISTRIBUTIONS. Distributions are subject to federal income tax,
and may also be subject to state or local taxes. If you live outside the
United States, your distributions could also be taxed by the country in
which you reside. Your distributions are taxable when they are paid,
whether you take them in cash or reinvest them. However, distributions
declared in December and paid in January are taxable as if they were paid
on December 31.
For federal tax purposes, the fund's income and short-term capital gain
distributions are taxed as dividends; long-term capital gain distributions,
if any, are taxed as long-term capital gains.
Mutual fund dividends from U.S. Government securities are generally free
from state and local income taxes. However, particular states may limit
this benefit, and some types of securities, such as repurchase agreements
and some agency-backed securities, may not qualify for the benefit. In
addition, some states may impose intangible property taxes. You should
consult your own tax adviser for details and up-to-date information on the
tax laws in your state.
Every January, the transfer agent will send you and the Internal Revenue
Service (IRS) a statement showing the taxable distributions paid to you in
the previous year.
There are tax requirements that all funds must follow in order to avoid
federal taxation. In its effort to adhere to these requirements, the fund
may have to limit its investment activity in some types of instruments. 
TRANSACTION DETAILS
THE FUND IS OPEN FOR BUSINESS and its NAV is normally calculated each day
the New York Stock Exchange (NYSE) is open. The following holiday closings
have been scheduled for 199   6    : New Year's Day, Washington's Birthday,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day. Although FMR expects the same holiday schedule to be
observed in the future, the NYSE may modify its holiday schedule at any
time. On any day that the NYSE closes early, the principal government
securities markets close early (such as on days in advance of holidays
generally observed by participants in such markets), or as permitted by the
SEC, the right is reserved to advance the time on that day by which
purchase and redemption orders must be received. 
To the extent that portfolio securities are traded in other markets on days
when the NYSE is closed, the fund's NAV may be affected on days when
investors do not have access to the fund to purchase or redeem shares.
Certain Fidelity funds may follow different holiday closing schedules.
THE FUND'S NAV is the value of a single share. The NAV is computed by
adding the value of the fund's investments, cash, and other assets,
subtracting its liabilities, and dividing the result by the number of
shares outstanding. The fund values its portfolio securities on the basis
of amortized cost. This method minimizes the effect of changes in a
security's market value and helps the fund maintain a stable $1.00 share
price.
THE FUND'S OFFERING PRICE (price to buy one share) and REDEMPTION PRICE
(price to sell one share) are its NAV. 
WHEN YOU SIGN YOUR ACCOUNT APPLICATION, you will be asked to certify that
your social security or taxpayer identification number is correct and that
you are not subject to 31% backup withholding for failing to report income
to the IRS. If you violate IRS regulations, the IRS can require the fund to
withhold 31% of your taxable distributions and redemptions.
YOU MAY INITIATE MANY TRANSACTIONS BY TELEPHONE. Fidelity may only be
liable for losses resulting from unauthorized transactions if it does not
follow reasonable procedures designed to verify the identity of the caller.
Fidelity will request personalized security codes or other information, and
may also record calls. You should verify the accuracy of the confirmation
statements immediately after receipt. If you do not want the ability to
redeem and exchange by telephone, call Fidelity Client Services at the
appropriate number listed on page  for instructions. Additional
documentation may be required from corporations, associations and certain
fiduciaries.
IF YOU ARE UNABLE TO REACH FIDELITY BY PHONE (for example, during periods
of unusual market activity), consider placing your order by mail. 
THE FUND RESERVES THE RIGHT TO SUSPEND THE OFFERING OF SHARES for a period
of time. The fund also reserves the right to reject any specific purchase
order, including certain purchases by exchange. See "Exchange Restrictions"
on page . Purchase orders may be refused if, in FMR's opinion, they would
disrupt management of the fund.
TO ALLOW FMR TO MANAGE THE FUND MOST EFFECTIVELY, you are urged to initiate
all trades as early in the day as possible and to notify Fidelity Client
Services in advance of large transactions.
WHEN YOU PLACE AN ORDER TO BUY SHARES, your shares will be purchased at the
next NAV calculated after your order is received and accepted by the
transfer agent. Note the following: 
(small solid bullet) All of your purchases must be made in U.S. dollars and
checks must be drawn on U.S. banks. 
(small solid bullet) Fidelity does not accept cash. 
(small solid bullet) When making a purchase with more than one check, each
check must have a value of at least $50.
(small solid bullet) The fund reserves the right to limit the number of
checks processed at one time.
(small solid bullet) If your check does not clear, your purchase will be
canceled and you could be liable for any losses or fees the fund or
Fidelity has incurred.
Net interest income for dividend purposes is determined by FSC on a daily
basis and shall be payable to shareholders of record at the time of its
declaration (including, for this purpose, holders of shares purchased, but
excluding holders of shares redeemed, on that day).
Shares purchased begin to earn income dividends on the following business
day.
WHEN YOU PLACE AN ORDER TO SELL SHARES, your shares will be sold at the
next NAV calculated after your order is received and accepted by the
transfer agent. Note the following: 
   (small solid bullet) Shares redeemed receive the dividends declared on
the day of redemption.    
(small solid bullet) The fund may withhold redemption proceeds until it is
reasonably assured that investments    credited to your account have been
received and collected.    
When the NYSE is closed (or when trading is restricted) for any reason
other than its customary weekend or holiday closings, or under any
emergency circumstances as determined by the SEC to merit such action, the
fund may suspend redemption or postpone payment dates. In cases of
suspension of the right of redemption, the request for redemption may
either be withdrawn or payment may be made based on the NAV next determined
after the termination of the suspension.
IF YOUR ACCOUNT BALANCE FALLS BELOW $100,000 due to redemption, the account
may be closed and the proceeds may be mailed to your address of record. You
will be given 30 days' notice that your account will be closed unless it is
increased to the minimum.
FIDELITY MAY CHARGE A FEE FOR SPECIAL SERVICES, such as providing
historical account documents, that are beyond the normal scope of its
services. 
EXCHANGE RESTRICTIONS
As a shareholder you have the privilege of exchanging shares of the fund
for shares of other Fidelity funds.
An exchange involves the redemption of all or a portion of the shares of
one fund and the purchase of shares of another fund.
BY TELEPHONE. Exchanges may be requested on any day the fund is open for
business by calling Fidelity Client Services at the appropriate number
listed on page .
BY MAIL. You may exchange shares on any business day by submitting written
instructions with an authorized signature which is on file for that
account. Written requests for exchanges should contain the fund name,
account number, the number of shares to be redeemed, and the name of the
fund to be purchased. Written requests for exchange should be mailed to
Fidelity    Client Services     at the address    shown     on page .
WHEN YOU PLACE AN ORDER TO EXCHANGE SHARES, shares will be redeemed at the
next determined NAV after your order is received and accepted by the
transfer agent. Shares of the fund to be acquired will be purchased at its
next determined NAV after redemption proceeds are made available. You
should note that, under certain circumstances, the fund may take up to
seven days to make redemption proceeds available for the exchange purchase
of shares of another fund. In addition, please note the following:
(small solid bullet) Exchanges will not be permitted until a completed and
signed account application is on file. 
(small solid bullet) The fund you are exchanging into must be registered
for sale in your state.
(small solid bullet) You may only exchange between accounts that are
registered in the same name, address, and taxpayer identification number.
(small solid bullet) Before exchanging into a fund, read its prospectus.
(small solid bullet) You will earn dividends in the acquired fund in
accordance with the fund's customary policy, normally on the day the
exchange request is received.
(small solid bullet) If you exchange into a fund with a sales charge, you
pay the percentage difference between that fund's sales charge and any
sales charge you have already paid in connection with the shares you are
exchanging. This may not apply if you are investing through a tax-saving
retirement plan.
(small solid bullet) Exchanges may have tax consequences for you.
(small solid bullet) Currently, there is no limit on the number of
exchanges out of the fund, nor are there any administrative or redemption
fees applicable to exchanges out of the fund. 
(small solid bullet) The fund reserves the right to refuse exchange
purchases by any person or group if, in FMR's judgment, the fund would be
unable to invest the money effectively in accordance with its investment
objective and policies, or would otherwise potentially be adversely
affected.
(small solid bullet) Your exchanges may be restricted or refused if the
fund receives or anticipates simultaneous orders affecting significant
portions of the fund's assets. In particular, a pattern of exchanges that
coincides with a "market timing" strategy may be disruptive to the fund.

INVESTMENT POLICIES AND LIMITATIONS
The following policies and limitations supplement those set forth in the
Prospectus. Unless otherwise noted, whenever an investment policy or
limitation states a maximum percentage of the fund's assets that may be
invested in any security or other asset, or sets forth a policy regarding
quality standards, such standard or percentage limitation will be
determined immediately after and as a result of the fund's acquisition of
such security or other asset. Accordingly, any subsequent change in values,
net assets or other circumstances will not be considered when determining
whether the investment complies with the fund's investment policies and
limitations.
The fund's fundamental investment policies and limitations cannot be
changed without approval by a "majority of the outstanding voting
securities" (as defined in the Investment Company Act of 1940 (1940 Act))
of the fund. However, except for the fundamental investment limitations
listed below, the investment policies and limitations described in this SAI
are not fundamental and may be changed without shareholder approval. THE
FOLLOWING ARE THE FUND'S FUNDAMENTAL INVESTMENT LIMITATIONS SET FORTH IN
THEIR ENTIRETY. THE FUND MAY NOT:
(1) with respect to 75% of the fund's total assets, purchase the securities
of any issuer (other than securities issued or guaranteed by the U.S.
Government    or any of     its agencies or instrumentalities) if, as a
result   ,     (a) more than 5% of the fund's total assets would be
invested in the securities of that issuer, or (b) the fund would hold more
than 10% of the outstanding voting securities of that issuer;
(2) issue senior securities, except as permitted under the Investment
Company Act of 1940;
(3) borrow money, except that the fund may (i) borrow money for temporary
or emergency purposes (not for leveraging or investment), and (ii) engage
in reverse repurchase agreements for any purpose; provided that (i) and
(ii) in combination do not exceed 33 1/3% of the fund's total assets
(including the amount borrowed) less liabilities (other than borrowings).
Any borrowings that come to exceed this amount will be reduced within three
days (not including Sundays and holidays) to the extent necessary to comply
with the 33 1/3% limitation;
(4) underwrite securities issued by others (except to the extent that the
fund may be considered to be an underwriter within the meaning of the
Securities Act of 1933 in the disposition of restricted securities);
(5) purchase the securities of any issuer (other than obligations issued or
guaranteed as to principal and interest by the government of the United
States, its agencies or instrumentalities) if, as a result, more than 25%
of the fund's total assets (taken at current value) would be invested in
the securities of issuers having their principal business activities in the
same industry;
(6) purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the fund
from investing in securities or other instruments backed by real estate or
securities of companies engaged in the real estate business); 
(7) purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments; or
(8) lend any security or make any other loan if, as a result, more than 33
1/3% of its total assets would be lent to other parties, but this
limitation does not apply to purchases of debt securities or to repurchase
agreements.
(9) The fund may, notwithstanding any other fundamental investment policy
or limitation, invest all of its assets in the securities of a single
open-end management investment company with substantially the same
fundamental investment objective, policies and limitations as the fund.
THE FOLLOWING LIMITATIONS ARE NOT FUNDAMENTAL AND MAY BE CHANGED WITHOUT
SHAREHOLDER APPROVAL.
(i) The fund may borrow money only (a) from a bank or from a registered
investment company or portfolio for which FMR or an affiliate serves as
investment adviser or (b) by engaging in reverse repurchase agreements with
any party. The fund will not purchase any security while borrowings
(excluding reverse repurchase agreements) representing more than 5% of its
total assets are outstanding. The fund will not borrow from other funds
advised by FMR or its affiliates if total outstanding borrowings
immediately after such borrowing would exceed 15% of the fund's total
assets.
(ii) The fund does not currently intend to sell securities short, unless it
owns or has the right to obtain securities equivalent in kind and amount to
the securities sold short, and provided that transactions in futures
contracts and options are not deemed to constitute selling securities
short.
(iii) The fund does not currently intend to purchase any security if, as a
result, more than 10% of its net assets would be invested in securities
that are deemed to be illiquid because they are subject to legal or
contractual restrictions on resale or because they cannot be sold or
disposed of in the ordinary course of business at approximately the prices
at which they are valued.
(iv) The fund does not currently intend to purchase securities on margin,
except that the fund may obtain such short-term credits as are necessary
for the clearance of transactions, and provided that margin payments in
connection with futures contracts and options on futures contracts shall
not constitute purchasing securities on margin.
(v) The fund does not currently intend to make loans, but this limitation
does not apply to purchases of debt securities or to repurchase agreements.
(vi) The fund does not currently intend to (a) purchase securities of other
investment companies, except in the open market where no commission except
the ordinary broker's commission is paid, or (b) purchase or retain
securities issued by other open-end investment companies. Limitations (a)
and (b) do not apply to securities received as dividends, through offers of
exchange, or as a result of a reorganization, consolidation, or merger.
(vii) The fund does not currently intend to purchase or sell futures
contracts or call options. This limitation does not apply to options
attached to, or acquired or traded together with, their underlying
securities, and does not apply to securities that incorporate features
similar to options or futures contracts.
(viii) The fund does not currently intend to invest in oil, gas, or other
mineral exploration or development programs or leases.
(ix) The fund does not currently intend to invest all of its assets in the
securities of a single open-end management investment company with
substantially the same fundamental investment objective, policies, and
limitations as the fund.
For the fund's policies on quality and maturity, see the section entitled
"Quality and Maturity" below.
AFFILIATED BANK TRANSACTIONS. The fund may engage in transactions with
financial institutions that are, or may be considered to be, "affiliated
persons" of the fund under the 1940 Act. These transactions may include
repurchase agreements with custodian banks; short-term obligations of, and
repurchase agreements with, the 50 largest U.S. banks (measured by
deposits); municipal securities; U.S. Government securities with affiliated
financial institutions that are primary dealers in these securities;
short-term currency transactions; and short-term borrowings. In accordance
with exemptive orders issued by the Securities and Exchange Commission
(SEC), the Board of Trustees has established and periodically reviews
procedures applicable to transactions involving affiliated financial
institutions.
DELAYED-DELIVERY TRANSACTIONS. The fund may buy and sell securities on a
delayed-delivery or when-issued basis. These transactions involve a
commitment by the fund to purchase or sell specific securities at a
predetermined price or yield, with payment and delivery taking place after
the customary settlement period for that type of security. Typically, no
interest accrues to the purchaser until the security is delivered.
When purchasing securities on a delayed-delivery basis, the fund assumes
the rights and risks of ownership, including the risk of price and yield
fluctuations. Because the fund is not required to pay for securities until
the delivery date, these risks are in addition to the risks associated with
the fund's other investments. If the fund remains substantially fully
invested at a time when delayed-delivery purchases are outstanding, the
delayed-delivery purchases may result in a form of leverage. When
delayed-delivery purchases are outstanding, the fund will set aside
appropriate liquid assets in a segregated custodial account to cover its
purchase obligations. When the fund has sold a security on a
delayed-delivery basis, the fund does not participate in further gains or
losses with respect to the security. If the other party to a
delayed-delivery transaction fails to deliver or pay for the securities,
the fund could miss a favorable price or yield opportunity, or could suffer
a loss.
The fund may renegotiate delayed-delivery transactions after they are
entered into, and may sell underlying securities before they are delivered,
which may result in capital gains or losses.
ILLIQUID INVESTMENTS are investments that cannot be sold or disposed of in
the ordinary course of business at approximately the prices at which they
are valued. Under the supervision of the Board of Trustees, FMR determines
the liquidity of the fund's investments and, through reports from FMR, the
Board monitors investments in illiquid instruments. In determining the
liquidity of the fund's investments, FMR may consider various factors,
including (1) the frequency of trades and quotations, (2) the number of
dealers and prospective purchasers in the marketplace, (3) dealer
undertakings to make a market, (4) the nature of the security (including
any demand or tender features), and (5) the nature of the marketplace for
trades (including the ability to assign or offset the fund's rights and
obligations relating to the investment).
Investments currently considered by the fund to be illiquid include
repurchase agreements not entitling the holder to payment of principal and
interest within seven days. 
INTERFUND BORROWING AND LENDING PROGRAM. Pursuant to an exemptive order
issued by the SEC, the fund has received permission to lend money to, and
borrow money from, other funds advised by FMR or its affiliates. Interfund
loans and borrowings normally extend overnight, but can have a maximum
duration of seven days. Loans may be called on one day's notice. A fund
will lend through the program only when the returns are higher than those
available from other short-term instruments (such as repurchase
agreements), and will borrow through the program only when the costs are
equal to or lower than the cost of bank loans. A fund may have to borrow
from a bank at a higher interest rate if an interfund loan is called or not
renewed. Any delay in repayment to a lending fund could result in a lost
investment opportunity or additional borrowing costs. The fund does not
currently intend to participate in the program as a lender.
PUT FEATURES entitle the holder to sell the security back to the issuer at
any time or at specified intervals. They are subject to the risk that the
put provider is unable to honor the put feature (purchase the security).
QUALITY AND MATURITY. Pursuant to procedures adopted by the Board of
Trustees, the fund may purchase only high-quality securities that FMR
believes present minimal credit risks. To be considered high-quality, a
security must be rated in accordance with applicable rules in one of the
two highest categories for short-term securities by at least two nationally
recognized rating services (or by one, if only one rating service has rated
the security); or, if unrated, judged to be of equivalent quality by FMR.
High-quality securities are divided into "first tier" and "second tier"
securities. First tier securities are those deemed to be in the highest
rating category (e.g., Standard & Poor's A-1), and second tier securities
are those deemed to be in the second highest rating category (e.g.,
Standard & Poor's A-2). Split-rated securities may be determined to be
either first tier or second tier based on applicable regulations.
The fund may not invest more than 5% of its total assets in second tier
securities. In addition, the fund may not invest more than 1% of its total
assets or $1 million (whichever is greater) in the second tier securities
of a single issuer.
The fund currently intends to limit its investments to securities with
remaining maturities of 397 days or less, and to maintain a dollar-weighted
average maturity of 90 days or less. When determining the maturity of a
security, the fund may look to an interest rate reset or demand feature.
REPURCHASE AGREEMENTS. In a repurchase agreement, the fund purchases a
security and simultaneously commits to sell that security back to the
original seller at an agreed-upon price. The resale price reflects the
purchase price plus an agreed-upon incremental amount which is unrelated to
the coupon rate or maturity of the purchased security.    To protect the
fund from the risk that the original seller will not fulfill its
obligation, the securities are held in an account of the fund     at a
bank, marked-to-market daily, and maintained at a value at least equal to
the sale price plus the accrued incremental amount. While it does not
presently appear possible to eliminate all risks from these transactions
(particularly the possibility that the value of the underlying security
will be less than the resale price   ,     as well as delays and costs to
the fund in connection with bankruptcy proceedings), it is the fund's
current policy to engage in repurchase agreement transactions with parties
whose creditworthiness has been reviewed and found satisfactory by FMR.
   RESTRICTED SECURITIES generally can be sold in privately negotiated
transactions, pursuant to an exemption from registration under the
Securities Act of 1933, or in a registered public offering. Where
registration is required, the fund may be obligated to pay all or part of
the registration expense and a considerable period may elapse between the
time it decides to seek registration and the time it may be permitted to
sell a security under an effective registration statement. If, during such
a period, adverse market conditions were to develop, the fund might obtain
a less favorable price than prevailed when it decided to seek registration
of the security. However, in general, the fund anticipates holding
restricted securities to maturity or selling them in an exempt
transaction.    
REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the fund
sells a portfolio instrument to another party, such as a bank or a
broker-dealer, in return for cash and agrees to repurchase the instrument
at a particular price and time. While a reverse repurchase agreement is
outstanding, the fund will maintain appropriate liquid assets in a
segregated custodial account to cover its obligation under the agreement.
The fund will enter into reverse repurchase agreements only with parties
whose creditworthiness has been found satisfactory by FMR. Such
transactions may increase fluctuations in the market value of the fund's
assets and may be viewed as a form of leverage.
SHORT SALES    "    AGAINST THE BOX   ".     The fund may sell securities
short when it owns or has the right to obtain securities equivalent in kind
or amount to the securities sold short. Short sales could be used to
protect the net asset value per share (NAV) of the fund in anticipation of
increased interest rates, without sacrificing the current yield of the
securities sold short. If the fund enters into a short sale against the
box, it will be required to set aside securities equivalent in kind and
amount to the securities sold short (or securities convertible or
exchangeable into such securities) and will be required to continue to hold
such securities while the short sale is outstanding. The fund will incur
transaction costs, including interest expenses, in connection with opening,
maintaining and closing short sales against the box.
STRIPPED GOVERNMENT SECURITIES. Stripped securities are created by
separating the income and principal components of a debt instrument and
selling them separately. U.S. Treasury STRIPS (Separate Trading of
Registered Interest and Principal of Securities) are created when the
coupon payments and the principal payment are stripped from an outstanding
Treasury bond by the Federal Reserve Bank. Bonds issued by the government
agencies also may be stripped in this fashion.
VARIABLE AND FLOATING RATE SECURITIES provide for periodic adjustments of
the interest rate paid on the security. Variable rate securities provide
for a specified periodic adjustment in the interest rate, while floating
rate securities have interest rates that change whenever there is a change
in a designated benchmark rate. Some variable or floating rate securities
have put features.
PORTFOLIO TRANSACTIONS
All orders for the purchase or sale of portfolio securities are placed on
behalf of the fund by FMR pursuant to authority contained in the management
contract. FMR has granted investment management authority to the
sub-adviser (see the section entitled "Management    Contract"), and the
sub-adviser is authorized to place orders for the purchase and sale of
portfolio securities, and will do so in     accordance with the policies
described below. FMR is also responsible for the placement of transaction
orders for other investment companies and accounts for which it or its
affiliates act as investment adviser. Securities purchased and sold by the
fund generally will be traded on a net basis (i.e., without commission). In
selecting broker-dealers, subject to applicable limitations of the federal
securities laws, FMR considers various relevant factors, including, but not
limited to, the size and type of the transaction; the nature and character
of the markets for the security to be purchased or sold; the execution of
efficiency, settlement capability, and financial condition of the
broker-dealer firm; the broker-dealer's execution services rendered on a
continuing basis; and the reasonableness of any commissions.
The fund may execute portfolio transactions with broker-dealers who provide
research and execution services to the fund or other accounts over which
FMR or its affiliates exercise investment discretion. Such services may
include advice concerning the value of securities; the advisability of
investing in, purchasing, or selling securities; and the availability of
securities or the purchasers or sellers of securities. In addition, such
broker-dealers may furnish analyses and reports concerning issuers,
industries, securities, economic factors and trends, portfolio strategy and
performance of accounts; effect securities transactions, and perform
functions incidental thereto (such as clearance and settlement). FMR
maintains a listing of broker-dealers who provide such services on a
regular basis. However, as many transactions on behalf of the fund are
placed with broker-dealers (including broker-dealers on the list) without
regard to the furnishing of such services, it is not possible to estimate
the proportion of such transactions directed to such broker-dealers solely
because such services were provided. The selection of such broker-dealers
generally is made by FMR (to the extent possible consistent with execution
considerations) based upon the quality of research and execution services
provided.
The receipt of research from broker-dealers that execute transactions on
behalf of the fund may be useful to FMR in rendering investment management
services to the fund or its other clients, and conversely, such research
provided by broker-dealers who have executed transaction orders on behalf
of other FMR clients may be useful to FMR in carrying out its obligations
to the fund. The receipt of such research has not reduced FMR's normal
independent research activities; however, it enables FMR to avoid the
additional expenses that could be incurred if FMR tried to develop
comparable information through its own efforts.
Subject to applicable limitations of the federal securities laws,
broker-dealers may receive commissions for agency transactions that are in
excess of the amount of commissions charged by other broker-dealers in
recognition of their research and execution services. In order to cause the
fund to pay such higher commissions, FMR must determine in good faith that
such commissions are reasonable in relation to the value of the brokerage
and research services provided by such executing broker-dealers, viewed in
terms of a particular transaction or FMR's overall responsibilities to the
fund and its other clients. In reaching this determination, FMR will not
attempt to place a specific dollar value on the brokerage and research
services provided, or to determine what portion of the compensation should
be related to those services.
FMR is authorized to use research services provided by and to place
portfolio transactions with brokerage firms that have provided assistance
in the distribution of shares of the fund or shares of other Fidelity funds
to the extent permitted by law. FMR may use research services provided by
and place agency transactions with Fidelity Brokerage Services, Inc. (FBSI)
and Fidelity Brokerage services (FBS), subsidiaries of FMR Corp., if the
commissions are fair, reasonable, and comparable to commissions charged by
non-affiliated, qualified brokerage firms for similar services. From
September 1992 through December 1994, FBS operated under the name Fidelity
Brokerage Services Limited, Inc. (FBSL). As of January 1995, FBSL was
converted to an unlimited liability company and assumed the name FBS. Prior
to September 4, 1992, FBSL operated under the name Fidelity Portfolio
Services, Ltd. (FPSL) as a wholly owned subsidiary of Fidelity
International Limited (FIL). Edward C. Johnson 3d is Chairman of FIL. Mr.
Johnson 3d, Johnson family members, and various trusts for the benefit of
the Johnson family own, directly or indirectly, more than 25% of the voting
common stock of FIL.
   Section 11(a) of the Securities Exchange Act of 1934 prohibits members
of national securities exchanges from executing exchange transactions for
accounts which they or their affiliates manage, unless certain requirements
are satisfied. Pursuant to such requirements, the Board of Trustees has
authorized FBSI to execute portfolio transactions on national securities
exchanges in accordance with approved procedures and applicable SEC rules.
The Trustees periodically review FMR's performance of its responsibilities
in connection with the placement of portfolio transactions on behalf of the
fund and review the commissions paid by the fund over representative
periods of time to determine if they are reasonable in relation to the
benefits to the fund.
For fiscal 1995, 1994 and 1993, the fund paid no brokerage commissions.    
During fiscal 1995 the fund paid no fees to brokerage firms that provided
research services.
From time to time the Trustees will review whether the recapture for the
benefit of the fund of some portion of the brokerage commissions or similar
fees paid by the fund on portfolio transactions is legally permissible and
advisable. The fund seeks to recapture soliciting broker-dealer fees on the
tender of portfolio securities, but at present no other recapture
arrangements are in effect. The Trustees intend to continue to review
whether recapture opportunities are available and are legally permissible
and, if so, to determine in the exercise of their business judgment whether
it would be advisable for the fund to seek such recapture.
Although the Trustees and officers of the fund are substantially the same
as those of other funds managed by FMR, investment decisions for the fund
are made independently from those of other funds managed by FMR or accounts
managed by FMR affiliates. It sometimes happens that the same security is
held in the portfolio of more than one of these funds or accounts.
Simultaneous transactions are inevitable when several funds and accounts
are managed by the same investment adviser, particularly when the same
security is suitable for the investment objective of more than one fund or
account.
When two or more funds are simultaneously engaged in the purchase or sale
of the same security, the prices and amounts are allocated in accordance
with procedures believed to be appropriate and equitable for each fund. In
some cases this system could have a detrimental effect on the price or
value of the security as far as the fund is concerned. In other cases,
however, the ability of the fund to participate in volume transactions will
produce better executions and prices for the fund. It is the current
opinion of the Trustees that the desirability of retaining FMR as
investment adviser to the fund outweighs any disadvantages that may be said
to exist from exposure to simultaneous transactions.
VALUATION
Fidelity Service Company (FSC) normally determines the fund's NAV at 4:00
p.m. Eastern time. The valuation of portfolio securities is determined as
of this time for the purpose of computing the fund's NAV.
Portfolio securities and other assets are valued on the basis of amortized
cost. This technique involves initially valuing an instrument at its cost
as adjusted for amortization of premium or accretion of discount rather
than its current market value. The amortized cost value of an instrument
may be higher or lower than the price the fund would receive if it sold the
instrument.
During periods of declining interest rates, the fund's yield based on
amortized cost valuation may be higher than would result if the fund used
market valuations to determine its NAV. The converse would apply during
periods of rising interest rates. 
Valuing the fund's investments on the basis of amortized cost and use of
the term "money market fund" are permitted pursuant to Rule 2a-7 under the
1940 Act. The fund must adhere to certain conditions under Rule 2a-7, as
summarized in the section entitled "Quality and Maturity" on page .
The Board of Trustees oversees FMR's adherence to the provisions of Rule
2a-7 and has established procedures designed to stabilize the fund's NAV at
$1.00. At such intervals as they deem appropriate, the Trustees consider
the extent to which NAV calculated by using market valuations would deviate
from $1.00 per share. If the Trustees believe that a deviation from the
fund's amortized cost per share may result in material dilution or other
unfair results to shareholders, the Trustees have agreed to take such
corrective action, if any, as they deem appropriate to eliminate or reduce,
to the extent reasonably practicable, the dilution or unfair results. Such
corrective action could include selling portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity; withholding dividends; redeeming shares in kind; establishing NAV
by using available market quotations; and such other measures as the
Trustees may deem appropriate.
PERFORMANCE
The fund may quote performance in various ways. All performance information
supplied by the fund in advertising is historical and is not intended to
indicate future returns. The fund's yield and total return fluctuate in
response to market conditions and other factors.
YIELD CALCULATIONS. To compute the fund's yield for a period, the net
change in value of a hypothetical account containing one share reflects the
value of additional shares purchased with dividends from the one original
share and dividends declared on both the original share and any additional
shares. The net change is then divided by the value of the account at the
beginning of the period to obtain a base period return. This base period
return is annualized to obtain a current annualized yield. The fund also
may calculate an effective yield by compounding the base period return over
a one-year period. In addition to the current yield, the fund may quote
yields in advertising based on any historical seven-day period. Yields for
the fund are calculated on the same basis as other money market funds, as
required by applicable regulations.
Yield information may be useful in reviewing the fund's performance and in
providing a basis for comparison with other investment alternatives.
However, the fund's yield fluctuates, unlike investments that pay a fixed
interest rate over a stated period of time. When comparing investment
alternatives, investors should also note the quality and maturity of the
portfolio securities of respective investment companies they have chosen to
consider.
Investors should recognize that in periods of declining interest rates the
fund's yield will tend to be somewhat higher than prevailing market rates,
and in periods of rising interest rates the fund's yield will tend to be
somewhat lower. Also, when interest rates are falling, the inflow of net
new money to the fund from the continuous sale of its shares will likely be
invested in instruments producing lower yields than the balance of the
fund's holdings, thereby reducing the fund's current yield. In periods of
rising interest rates, the opposite can be expected to occur.
TOTAL RETURN CALCULATIONS. Total returns quoted in advertising reflect all
aspects of the fund's return, including the effect of reinvesting dividends
and capital gain distributions, and any change in the fund's NAV over a
stated period. Average annual total returns are calculated by determining
the growth or decline in value of a hypothetical historical investment in
the fund over a stated period, and then calculating the annually compounded
percentage rate that would have produced the same result if the rate of
growth or decline in value had been constant over the period. For example,
a cumulative total return of 100% over ten years would produce an average
annual total return of 7.18%, which is the steady annual rate of return
that would equal 100% growth on a compounded basis in ten years. While
average annual total returns are a convenient means of comparing investment
alternatives, investors should realize that the fund's performance is not
constant over time, but changes from year to year, and that average annual
total returns represent averaged figures as opposed to the actual
year-to-year performance of the fund.
In addition to average annual total returns, the fund may quote unaveraged
or cumulative total returns reflecting the simple change in value of an
investment over a stated period. Average annual and cumulative total
returns may be quoted as a percentage or as a dollar amount, and may be
calculated for a single investment, a series of investments, or a series of
redemptions, over any time period. Total returns may be broken down into
their components of income and capital (including capital gains and changes
in share price) in order to illustrate the relationship of these factors
and their contributions to total return. Total returns may be quoted on a
before-tax or after-tax basis. Total returns, yields, and other performance
information may be quoted numerically or in a table, graph, or similar
illustration.

</TABLE>
 
* From December 16, 1988 (commencement of operations).
The following table shows the income and capital elements of the fund's
cumulative total return. The table compares the fund's return to the record
of the Standard & Poor's Composite Index of 500 Stocks (S&P 500), the Dow
Jones Industrial Average (DJIA), and the cost of living (measured by the
Consumer Price Index, or CPI) over the same period. The CPI information is
as of the month end closest to the initial investment date for the fund.
The S&P 500 and DJIA comparisons are provided to show how the fund's total
return compared to the record of a broad average of common stocks and a
narrower set of stocks of major industrial companies, respectively, over
the same period. Of course, since the fund invests in short-term
fixed-income securities, common stocks represent a different type of
investment from the fund. Common stocks generally offer greater growth
potential than the fund, but generally experience greater price volatility,
which means greater potential for loss. In addition, common stocks
generally provide lower income than a fixed-income investment such as the
fund. Figures for the S&P 500 and DJIA are based on the prices of unmanaged
groups of stocks and, unlike the fund's returns, do not include the effect
of paying brokerage commissions or other costs of investing.
During the period from December 16, 1988 (commencement of operations) to
August 31, 1995, a hypothetical $10,000 investment in the fund would have
grown to $   14,401    , assuming all distributions were reinvested. This
was a period of fluctuating interest rates and the figures below should not
be considered representative of the dividend income or capital gain or loss
that could be realized from an investment in the fund today.

</TABLE>
 
* From December 16, 1988 (commencement of operations).
** From month-end closest to initial investment date.
Explanatory Notes: With an initial investment of $10,000 made on December
16, 1988, the net amount invested in fund shares was $10,000. The cost of
the initial investment ($10,000), together with the aggregate cost of
reinvested dividend distributions for the period covered (their cash value
at the time they were reinvested), amounted to $   14,401    . If
distributions had not been reinvested, the amount of distributions earned
from the fund over time would have been smaller, and cash payments
(dividends) for the period would have amounted to $   3,657    . The fund
did not distribute any capital gains during the period. Tax consequences of
different investments have not been factored into the above figures.
PERFORMANCE COMPARISONS. The fund's performance may be compared to the
performance of other mutual funds in general, or to the performance of
particular types of mutual funds. These comparisons may be expressed as
mutual fund rankings prepared by Lipper Analytical Services, Inc. (Lipper),
an independent service located in Summit, New Jersey that monitors the
performance of mutual funds. Lipper generally ranks funds on the basis of
total return, assuming reinvestment of distributions, but does not take
sales charges or redemption fees into consideration, and is prepared
without regard to tax consequences. Lipper may also rank funds based on
yield. In addition to the mutual fund rankings, the fund's performance may
be compared to stock, bond, and money market mutual fund performance
indices prepared by Lipper or other organizations. When comparing these
indices, it is important to remember the risk and return characteristics of
each type of investment. For example, while stock mutual funds may offer
higher potential returns, they also carry the highest degree of share price
volatility. Likewise, money market funds may offer greater stability of
principal, but generally do not offer the higher potential returns
available from stock mutual funds.
From time to time, the fund's performance may also be compared to other
mutual funds tracked by financial or business publications and periodicals.
For example, the fund may quote Morningstar, Inc. in its advertising
materials. Morningstar, Inc. is a mutual fund rating service that rates
mutual funds on the basis of risk-adjusted performance. Rankings that
compare the performance of Fidelity funds to one another in appropriate
categories over specific periods of time may also be quoted in advertising.
The fund may be compared in advertising to Certificates of Deposit (CDs) or
other investments issued by banks or other depository institutions. Mutual
funds differ from bank investments in several respects. For example, the
fund may offer greater liquidity or higher potential returns than CDs, the
fund does not guarantee your principal or your return, and fund shares are
not FDIC insured.
Fidelity may provide information designed to help individuals understand
their investment goals and explore various financial strategies. Such
information may include information about current economic, market, and
political conditions; materials that describe general principles of
investing, such as asset allocation, diversification, risk tolerance, and
goal setting; questionaires designed to help create a personal financial
profile; worksheets used to assess savings needs based on assumed rates of
inflation and hypothetical rates of return; and action plans offering
investment alternatives. Materials may also include discussions of
Fidelity's asset allocation funds and other Fidelity funds, products, and
services.
Ibbotson Associates of Chicago, Illinois (Ibbotson) provides historical
returns of the capital markets in the United States, including common
stocks, small capitalization stocks, long-term corporate bonds,
intermediate-term government bonds, long-term government bonds, Treasury
bills, the U.S. rate of inflation (based on the CPI), and combinations of
various capital markets. The performance of these capital markets is based
on the returns of different indices.
Fidelity funds may use the performance of these capital markets in order to
demonstrate general risk-versus-reward investment scenarios. Performance
comparisons may also include the value of a hypothetical investment in any
of these capital markets. The risks associated with the security types in
any capital market may or may not correspond directly to those of the
funds. Ibbotson calculates total returns in the same method as the funds.
The funds may also compare performance to that of other compilations or
indices that may be developed and made available in the future.
A fund may compare its performance or the performance of securities in
which it may invest to averages published by IBC USA (Publications), Inc.
of Ashland, Massachusetts. These averages assume reinvestment of
distributions. The IBC/Donoghue's MONEY FUND AVERAGES   (Trademark)     All
Government, which is reported in the MONEY FUND REPORT(registered
trademark), covers over    263     U.S. Government money market funds.
In advertising materials, Fidelity may reference or discuss its products
and services, which may include other Fidelity funds; retirement investing;
brokerage products and services; model portfolios or allocations; saving
for college or other goals; charitable giving; and the Fidelity credit
card. In addition, Fidelity may quote or reprint financial or business
publications and periodicals as they relate to current economic and
political conditions, fund management, portfolio composition, investment
philosophy, investment techniques, the desirability of owning a particular
mutual fund, and Fidelity services and products. Fidelity may also reprint,
and use as advertising and sales literature, articles from Fidelity Focus,
a quarterly magazine provided free of charge to Fidelity fund shareholders.
The fund may present its fund number, Quotron   (Trademark)     number, and
CUSIP number, and discuss or quote its current portfolio manager.
The fund may be available for purchase through retirement plans or other
programs offering deferral of, or exemption from, income taxes, which may
produce superior after-tax returns over time. For example, a $1,000
investment earning a taxable return of 10% annually would have an after-tax
value of $1,949 after ten years, assuming tax was deducted from the return
each year at a 31% rate. An equivalent tax-deferred investment would have
an after-tax value of $2,100 after ten years, assuming tax was deducted at
a 31% rate from the tax-deferred earnings at the end of the ten-year
period.
As of August 31, 1995, FMR advised over $   26.5     billion in tax-free
fund assets, $   79     billion in money market fund assets, $   218    
billion in equity fund assets, $   56     billion in international fund
assets, and $   23     billion in Spartan fund assets. The fund may
reference the growth and variety of money market mutual funds and the
adviser's innovation and participation in the industry. The equity funds
under management figure represents the largest amount of equity fund assets
under management by a mutual fund investment adviser in the United States,
making FMR America's leading equity (stock) fund manager. FMR, its
subsidiaries, and affiliates maintain a worldwide information and
communications network for the purpose of researching and managing
investments abroad.
In addition to performance rankings, the fund may compare its total expense
ratio to the average total expense ratio of similar funds tracked by
Lipper. A fund's total expense ratio is a significant factor in comparing
bond and money market investments because of its effect on yield.
ADDITIONAL PURCHASE, EXCHANGE AND REDEMPTION INFORMATION
If the Trustees determine that existing conditions make cash payments
undesirable, redemption payments may be made in whole or in part in
securities or other property, valued for this purpose as they are valued in
computing the fund's NAV. Shareholders receiving securities or other
property on redemption may realize a gain or loss for tax purposes, and
will incur any costs of sale, as well as the associated inconveniences.
Pursuant to Rule 11a-3 under the 1940 Act, the fund is required to give
shareholders at least 60 days' notice prior to terminating or modifying its
exchange privilege. Under the Rule, the 60-day notification requirement may
be waived if (i) the only effect of a modification would be to reduce or
eliminate an administrative fee, redemption fee or deferred sales charge
ordinarily payable at the time of an exchange, or (ii) the fund suspends
the redemption of the shares to be exchanged as permitted under the 1940
Act or the rules and regulations thereunder, or the fund to be acquired
suspends the sale of its shares because it is unable to invest amounts
effectively in accordance with its investment objective and policies.
In the prospectus, the fund has notified shareholders that it reserves the
right at any time, without prior notice, to refuse exchange purchases by
any person or group if, in FMR's judgment, the fund would be unable to
invest effectively in accordance with its investment objective and
policies, or would otherwise potentially be adversely affected.
DISTRIBUTION   S     AND TAXES
DISTRIBUTIONS. If you request to have distributions mailed to you and the
U.S. Postal Service cannot deliver your checks, or if your checks remain
uncashed for six months, Fidelity may reinvest your distributions at the
then-current NAV. All subsequent distributions will then be reinvested
until you provide Fidelity with alternate instructions.
DIVIDENDS. Because the fund's income is primarily derived from interest,
dividends from the fund generally will not qualify for the
dividends-received deduction available to corporate shareholders.
Short-term capital gains are distributed as dividend income, but do not
qualify for the dividends received deduction. A portion of the fund's
dividends derived from certain U.S. Government obligations may be exempt
from state and local taxation. The fund will send each shareholder a notice
in January describing the tax status of dividend and capital gain
distributions (if any) for the prior year.
CAPITAL GAIN DISTRIBUTIONS. The fund may distribute any net realized
short-term capital gains once a year or more often as necessary, to
maintain its net asset value at $1.00 per share. The fund does not
anticipate earning long-term capital gains on securities held by the fund.
   As of August 31, 1995, the fund had a capital loss carryforward
aggregating approximately $334,000. This loss carryforward, of which
$4,000, $47,000, $178,000 and $105,000 will expire on August 31, 2000,
2001, 2002, and 2003, respectively, is available to offset future capital
gains.    
STATE AND LOCAL TAX ISSUES. For mutual funds organized as business trusts,
state laws provide for a pass-through of the state and local income tax
exemption afforded to direct owners of U.S. Government securities. Some
states limit this to mutual funds that invest a certain amount in U.S.
Government securities, and some types of securities, such as repurchase
agreements and some agency-backed securities, but may not qualify for this
benefit. The tax treatment of your dividend distributions from the fund
will be the same as if you directly owned your proportionate share of the
U.S. Government securities in the fund's portfolio. Because the income
earned on most U.S. Government securities in which the fund invests is
exempt form state and local income taxes, the portion of your dividends
from the fund attributable to these securities will also be free from
income taxes. The exemption from state and local income taxation does not
preclude states from assessing other taxes on the ownership of U.S.
Government securities. In a number of states corporate franchise (income)
tax laws do not exempt interest earned on U.S. Government securities
whether such securities are held directly or through a fund.
TAX STATUS OF THE FUNDS. The fund intends to qualify each year as a
"regulated investment company" for tax purposes so that it will not be
liable for federal tax on income and capital gains distributed to
shareholders. In order to qualify as a regulated investment company and
avoid being subject to federal income or excise taxes at the fund level,
the fund intends to distribute substantially all of its net investment
income and net realized capital gains within each calendar year as well as
on a fiscal year basis. 
The fund is treated as a separate entity from the other funds of Fidelity
Money Market Trust for tax purposes.
OTHER TAX INFORMATION. The information above is only a summary of some of
the tax consequences generally affecting the fund and its shareholders, and
no attempt has been made to discuss individual tax consequences. In
addition to federal income taxes, shareholders may be subject to state and
local taxes on fund distributions, and shares may be subject to state and
local personal property taxes. Investors should consult their tax advisers
to determine whether the fund is suitable to their particular tax
situation.
FMR
All of the stock of FMR is owned by FMR Corp., its parent organized in
1972. The voting common stock of FMR Corp. is divided into two classes.
Class B is held predominantly by members of the Edward C. Johnson 3d family
and is entitled to 49% of the vote on any matter acted upon by the voting
common stock. Class A is held predominantly by non-Johnson family member
employees of FMR Corp. and its affiliates and is entitled to 51% of the
vote on any such matter. The Johnson family group and all other Class B
shareholders have entered into a shareholders' voting agreement under which
all Class B shares will be voted in accordance with the majority vote of
Class B shares. Under the 1940 Act, control of a company is presumed where
one individual or group of individuals owns more than 25% of the voting
stock of that company. Therefore, through their ownership of voting common
stock and the execution of the shareholders' voting agreement, members of
the Johnson family may be deemed, under the 1940 Act, to form a controlling
group with respect to FMR Corp.
At present, the principal operating activities of FMR Corp. are those
conducted by three of its divisions as follows: FSC, which is the transfer
and shareholder servicing agent for certain funds advised by FMR; FIIOC,
which performs shareholder servicing functions for institutional customers
and funds sold through intermediaries; and Fidelity Investments Retail
Marketing Company, which provides marketing services to various companies
within the Fidelity organization.
Fidelity investment personnel may invest in securities for their own
account pursuant to a code of ethics that sets forth all employees'
fiduciary responsibilities regarding the funds, establishes procedures for
personal investing and restricts certain transactions. For example, all
personal trades in most securities require pre-clearance, and participation
in initial public offerings is prohibited. In addition, restrictions on the
timing of personal investing in relation to trades by Fidelity funds and on
short-term trading have been adopted.
TRUSTEES AND OFFICERS
The Trustees and executive officers of the trust are listed below. Except
as indicated, each individual has held the office shown or other offices in
the same company for the last five years. Trustees and officers elected or

capacities. All persons named as Trustees also serve in similar capacities
for other funds advised by FMR. The business address of each Trustee and
officer who is an "interested person" (as defined in the 1940 Act) is 82
Devonshire Street, Boston, Massachusetts 02109, which is also the address
of FMR. The business address of all the other Trustees is Fidelity
Investments, P.O. Box 9235, Boston, Massachusetts 02205-9235. Those
Trustees who are "interested persons" by virtue of their affiliation with
either the trust or FMR are indicated by an asterisk (*).

* Information is as of December 31, 1994 for 206 funds in the complex.
** Interested trustees of the fund are compensated by FMR.
Under a retirement program adopted in July 1988, the non-interested
Trustees, upon reaching age 72, become eligible to participate in a
retirement program under which they receive payments during their lifetime
from a fund based on their basic trustee fees and length of service. The
obligation of a fund to make such payments is not secured or funded.
Trustees become eligible if, at the time of retirement, they have served on
the Board for at least five years. Currently, Messrs. Ralph S. Saul,
William R. Spaulding, Bertram H. Witham, and David L. Yunich, all former
non-interested Trustees, receive retirement benefits under the program.
   As of September 30, 1995, there were no owners of record or beneficially
of 5% or more of outstanding shares of the fund.    
On    August 31    , 1995, the Trustees and officers of the fund owned, in
the aggregate, less than 1% of the fund's total outstanding shares.
MANAGEMENT CONTRACT
The fund employs FMR to furnish investment advisory and other services.
Under its management contract with the fund, FMR acts as investment adviser
and, subject to the supervision of the Board of Trustees, directs the
investments of the fund in accordance with its investment objective,
policies and limitations. FMR also provides the fund with all necessary
office facilities and personnel for servicing the fund's investments,
compensates all officers of the fund and all Trustees who are "interested
persons" of the fund or of FMR, and all personnel of the fund or FMR
performing services relating to research, statistical and investment
activities.
In addition, FMR or its affiliates, subject to the supervision of the Board
of Trustees, provide the management and administrative services necessary
for the operation of the fund. These services include providing facilities
for maintaining the fund's organization; supervising relations with
custodians, transfer and pricing agents, accountants, underwriters, and
other persons dealing with the fund; preparing all general shareholder
communications and conducting shareholder relations; maintaining the fund's
records and the registration of the fund's shares under federal and state
laws; developing management and shareholder services for the fund; and
furnishing reports, evaluations and analyses on a variety of subjects to
the Trustees.
FMR is responsible for the payment of all expenses of the fund with certain
exceptions. Specific expenses payable by FMR include, without limitation,
expenses for the typesetting, printing, and mailing proxy materials to
shareholders; legal expenses, and the fees of the custodian, and auditor;
costs of typesetting, printing, and mailing prospectuses and statements of
additional information, notices and reports to shareholders; and the fund's
proportionate share of insurance premiums and Investment Company Institute
dues. FMR also provides for transfer agent and dividend disbursing services
through FIIOC and portfolio and general accounting record maintenance
through FSC. 
FMR pays all other expenses of the fund with the following exceptions: fees
and expenses of all Trustees of the Trust who are not "interested persons"
of the Trust or FMR (the non-interested Trustees); taxes; brokerage
commissions (if any); and such nonrecurring expenses as may arise,
including costs of any litigation to which a fund may be a party, and any
obligation it may have to indemnify the officers and Trustees with respect
to litigation.
 FMR is the fund's manager pursuant to a management contract dated December
29, 1994 which was approved by shareholders on December 8, 1994. The
management fee paid to FMR is reduced by an amount equal to the fees and
expenses paid by the fund to the non-interested Trustees.
For the services of FMR under the contract, the fund pays FMR a monthly
management fee at the annual rate of 0.42% of the average net assets of the
fund throughout the month. For the fiscal years ended August 31, 1995,
1994, and 1993, FMR received $   8,395,963    , $   6,327,789    , and
$   5,612,942    , respectively, after reduction of fees and expenses
   paid by the fund to     the non-interested Trustees.
FMR may, from time to time, voluntarily reimburse all or a portion of the
fund's operating expenses (exclusive of interest, taxes, brokerage
commissions, and extraordinary expenses). FMR retains the ability to be
repaid for these expense reimbursements in the amount that expenses fall
below the limit prior to the end of the fiscal year. Expense reimbursements
by FMR will increase the fund's total returns and yield and repayment of
the reimbursement by the fund will lower its total returns and yield.
To comply with the California Code of Regulations, FMR will reimburse the
fund if and to the extent that the fund's aggregate annual operating
expenses exceed specified percentages of its average net assets. The
applicable percentages are 2 1/2% of the first $30 million, 2% of the next
$70 million, and 1 1/2% of average net assets in excess of $100 million.
When calculating the fund's expenses for purposes of this regulation, the
fund may exclude interest, taxes, brokerage commissions, and extraordinary
expenses.
SUB-ADVISER. FMR has entered into a sub-advisory agreement with FMR Texas
pursuant to which FMR Texas has primary responsibility for providing
portfolio investment management services to the fund.
Under the sub-advisory agreement, dated December 29, 1994, which was
approved by shareholders on December 8, 1994, FMR pays FMR Texas fees equal
to 50% of the management fee payable to FMR under its management contract
with the fund. The fees paid to FMR Texas are not reduced by any voluntary
or mandatory expense reimbursements that may be in effect from time to
time. On behalf of the fund, for fiscal 1995, 1994, and 1993, FMR paid FMR
Texas fees of $   4,197,982    , $   3,163,895    , and $2,806,471,
respectively.
   CONTRACTS WITH FMR AFFILIATES
FIIOC is transfer, dividend disbursing, and shareholders' servicing agent
for the fund. The costs of these services are borne by FMR pursuant to its
management contract with the fund. FSC calculates the fund's NAV and
dividends, and maintains the fund's general accounting records. The cost of
these services are also borne by FMR pursuant to its management contract
with the fund. 
The fund has a distribution agreement with FDC, a Massachusetts corporation
organized on July 18, 1960. FDC is a broker-dealer registered under the
Securities Exchange Act of 1934 and is a member of the National Association
of Securities Dealers, Inc. The distribution agreement calls for FDC to use
all reasonable efforts, consistent with its other business, to secure
purchasers for shares of the fund, which are continuously offered at net
asset value. Promotional and administrative expenses in connection with the
offer and sale of shares are paid by FMR.    
DISTRIBUTION AND SERVICE PLAN
The Trustees have approved a Distribution and Service Plan on behalf of the
fund (the Plan) pursuant to Rule 12b-1 under the 1940 Act (the Rule). The
Rule provides in substance that a mutual fund may not engage directly or
indirectly in financing any activity that is primarily intended to result
in the sale of shares of a fund except pursuant to a plan on behalf of the
fund under the Rule. The Plan, as approved by the Trustees, allows the fund
and FMR to incur certain expenses that might be considered to constitute
indirect payment by the fund of distribution expenses.
Under the Plan, if the payment of management fees by the fund to FMR is
deemed to be indirect financing by the fund of the distribution of its
shares, such payment is authorized by the Plan. The Plan specifically
recognizes that FMR        may use its management fee revenue,    as well
as its past profits     or    its     other resources    from any other
source     to    reimburse FDC for expenses incurred in connection with the
distribution of fund shares, including     payments    made     to third
parties that assist in selling shares of the fund, or to third parties,
including banks, that render shareholder support services. The Trustees
have not authorized such payments to date.
Prior to approving the Plan, the Trustees carefully considered all
pertinent factors relating to the implementation of the Plan, and have
determined that there is a reasonable likelihood that the Plan will benefit
the fund and its shareholders. In particular, the Trustees noted that the
Plan does not authorize payments by the fund other than those made to FMR
under its management contract with the fund. To the extent that the Plan
gives FMR and FDC greater flexibility in connection with the distribution
of shares of the fund, additional sales of fund shares may result.
Furthermore, certain shareholder support services may be provided more
effectively under the Plan by local entities with whom shareholders have
other relationships.
The Plan was approved by shareholders of the fund on December 8, 1994. The
Plan was approved by shareholders in connection with a reorganization
transaction on December 29, 1994, pursuant to an Agreement and Plan of
Conversion.
The Glass-Steagall Act generally prohibits federally and state chartered or
supervised banks from engaging in the business of underwriting, selling, or
distributing securities. Although the scope of this prohibition under the
Glass-Steagall Act has not been clearly defined by the courts or
appropriate regulatory agencies, FDC believes that the Glass-Steagall Act
should not preclude a bank from performing shareholder support services, or
servicing and recordkeeping functions. FDC intends to engage banks only to
perform such functions. However, changes in federal or state statutes and
regulations pertaining to the permissible activities of banks and their
affiliates or subsidiaries, as well as further judicial or administrative
decisions or interpretations, could prevent a bank from continuing to
perform all or a part of the contemplated services. If a bank were
prohibited from so acting, the Trustees would consider what actions, if
any, would be necessary to continue to provide efficient and effective
shareholder services. In such event, changes in the operation of the fund
might occur, including possible termination of any automatic investment or
redemption or other services then provided by the bank. It is not expected
that shareholders would suffer any adverse financial consequences as a
result of any of these occurrences. In addition, state securities laws on
this issue may differ from the interpretations of federal law expressed
herein, and banks and other financial institutions may be required to
register as dealers pursuant to state law.
The fund may execute portfolio transactions with, and purchase securities
issued by, depository institutions that receive payments under the Plan. No
preference for the instruments of such depository institutions will be
shown in the selection of investments.
DESCRIPTION OF THE TRUST
TRUST ORGANIZATION. Retirement Government Money Market Portfolio is a fund
of Fidelity Money Market Trust, an open-end management investment company
originally organized as a Massachusetts business trust on August 21, 1978
pursuant to a Declaration of Trust that was amended and restated November
1, 1989. On December 29, 1994, the trust was converted to a Delaware
business trust pursuant to an agreement approved by shareholders on
December 8, 1994. The Delaware trust, which was organized on June 20, 1991
under the name of Fidelity Money Market Trust II, succeeded to the name
Fidelity Money Market Trust on December 29, 1994. Currently, there are
   three     funds of the trust:    Rated     Money Market; Retirement
Money Market    Portfolio    ; and Retirement Government Money Market
Portfolio. The Trust Instrument permits the Trustees to create additional
funds.
In the event that FMR ceases to be the investment adviser to the fund, the
right of the trust or fund to use the identifying name "Fidelity" may be
withdrawn.
The assets of the trust received for the issue or sale of shares of each
fund and all income, earnings, profits, and proceeds thereof, subject only
to the rights of creditors, are especially allocated to such fund, and
constitute the underlying assets of such fund. The underlying assets of
each fund are segregated on the books of account, and are to be charged
with the liabilities with respect to such fund and with a share of the
general expenses of the trust. Expenses with respect to the trust are to be
allocated in proportion to the asset value of the respective funds, except
where allocations of direct expense can otherwise be fairly made. The
officers of the trust, subject to the general supervision of the Board of
Trustees, have the power to determine which expenses are allocable to a
given fund, or which are general or allocable to all of the funds. In the
event of the dissolution or liquidation of the trust, shareholders of each
fund are entitled to receive as a class the underlying assets of such fund
available for distribution.
SHAREHOLDER AND TRUSTEE LIABILITY. The trust is a business trust organized
under Delaware law. Delaware law provides that shareholders shall be
entitled to the same limitations of personal liability extended to
stockholders of private corporations for profit. The courts of some states,
however, may decline to apply Delaware law on this point. The Trust
Instrument contains an express disclaimer of shareholder liability for the
debts, liabilities, obligations, and expenses of the trust and requires
that a disclaimer be given in each contract entered into or executed by the
trust or the Trustees. The Trust Instrument provides for indemnification
out of each fund's property of any shareholder or former shareholder held
personally liable for the obligations of the fund. The Trust Instrument
also provides that each fund shall, upon request, assume the defense of any
claim made against any shareholder for any act or obligation of the fund
and satisfy any judgment thereon. Thus, the risk of a shareholder incurring
financial loss on account of shareholder liability is limited to
circumstances in which Delaware law does not apply, no contractual
limitation of liability was in effect, and the fund is unable to meet its
obligations. FMR believes that, in view of the above, the risk of personal
liability to shareholders is extremely remote.
The Trust Instrument further provides that the Trustees, if they have
exercised reasonable care, shall not be personally liable to any person
other than the trust or its shareholders; moreover, the Trustees shall not
be liable for any conduct whatsoever, provided that Trustees are not
protected against any liability to which they would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence, or reckless
disregard of the duties involved in the conduct of their office. 
VOTING RIGHTS. Each fund's capital consists of shares of beneficial
interest. As a shareholder, you receive one vote for each dollar value of
NAV you own. The shares have no preemptive or conversion rights; the voting
and dividend rights, the right of redemption, and the privilege of exchange
are described in the Prospectus. Shares are fully paid and nonassessable,
except as set forth under the heading "Shareholder and Trustee Liability"
above. Shareholders representing 10% or more of the trust or a fund may, as
set forth in the Trust Instrument, call meetings of the trust or a fund for
any purpose related to the trust or fund, as the case may be, including, in
the case of a meeting of the entire trust, the purpose of voting on removal
of one or more Trustees. 
The trust or any fund may be terminated upon the sale of its assets to, or
merger with, another open-end management investment company or series
thereof, or upon liquidation and distribution of its assets. Generally such
terminations must be approved by vote of the holders of a majority of the
trust or the fund, as determined by the current value of each shareholder's
investment in the fund or trust; however, the Trustees may, without prior
shareholder approval, change the form of organization of the trust by
merger, consolidation, or incorporation. If not so terminated or
reorganized, the trust and its funds will continue indefinitely.
Under the Trust Instrument, the Trustees may, without shareholder vote,
cause the trust to merge or consolidate into one or more trusts,
partnerships, or corporations, or cause the trust to be incorporated under
Delaware law, so long as the surviving entity is an open-end management
investment company that will succeed to or assume the trust registration
statement. Each fund may invest all of its assets in another investment
company.
CUSTODIAN. Morgan Guaranty Trust Company of New York, 60 Wall Street, New
York, NY, is custodian of the assets of the fund. The custodian is
responsible for the safekeeping of a fund's assets and the appointment of
the subcustodian banks and clearing agencies. The custodian takes no part
in determining the investment policies of a fund or in deciding which
securities are purchased or sold by a fund. However, a fund may invest in
obligations of the custodian and may purchase securities from or sell
securities to the custodian. The Bank of New York and Chemical Bank   ,    
each headquartered in New York, also may serve as a special purpose
custodian of certain assets in connection with pooled repurchase agreement
transactions.
FMR, its officers and directors, its affiliated companies, and the Board of
Trustees may, from time to time, conduct transactions with various banks,
including banks serving as custodians for certain funds advised by FMR.
Transactions that have occurred to date include mortgages and personal and
general business loans. In the judgment of FMR, the terms and conditions of
those transactions were not influenced by existing or potential custodial
or other fund relationships.
AUDITOR.    Coopers & Lybrand L.L.P., 1999 Bryan Street, Dallas, Texas,    
serves as the fund's independent accountant. The auditor examines financial
statements for the fund and provides other audit, tax, and related
services.

year ended August 31, 1995, are included in the fund's Annual Report, which

KEY FACTS
 
 
WHO MAY WANT TO INVEST
The fund is generally intended for investors in tax-saving retirement plans
such as defined contribution plans, 403(b) accounts, defined benefit plans
and 457 plans.
The fund is designed for investors who would like to earn current income
while preserving the value of their investment.
The rate of income will vary from day to day, generally reflecting
short-term interest rates.
The fund is managed to keep its share price stable at $1.00.
The fund does not constitute a balanced investment plan. However, because
it emphasizes stability, it could be well-suited for a portion of your
savings.

EXPLANATION OF TERMS
TOTAL RETURN is the change in value of an investment in the fund over a
given period, assuming reinvestment of any dividends and capital gains. A
CUMULATIVE TOTAL RETURN reflects actual performance over a stated period of
time. An AVERAGE ANNUAL TOTAL RETURN is a hypothetical rate of return that,
if achieved annually, would have produced the same cumulative total return
if performance had been constant over the entire period. Average annual
total returns smooth out variations in performance; they are not the same
as actual year-by-year results.
YIELD refers to the income generated by an investment in the fund over a
given period of time, expressed as an annual percentage rate. When a yield
assumes that income earned is reinvested, it is called an EFFECTIVE YIELD.
SEVEN-DAY YIELD illustrates the income earned by an investment in the fund
over a recent seven-day period. Since money market funds maintain a stable
$1.00 share price, current seven-day yields are the most common
illustration of money market fund performance.
THE CONSUMER PRICE INDEX is a widely recognized measure of inflation
calculated by the U.S. Government.
The fund's recent strategies, performance, and holdings are detailed twice
a year in financial reports, which are sent to all shareholders.

number listed on page .
TOTAL RETURNS AND YIELDS ARE BASED ON PAST RESULTS AND ARE NOT AN
INDICATION OF FUTURE PERFORMANCE.
   THE FUND IN DETAIL    
 
 
CHARTER
RETIREMENT MONEY MARKET IS A MUTUAL FUND: an investment that pools
shareholders' money and invests it toward a specified goal. The fund is a
diversified fund of Fidelity Money Market Trust, an open-end management
investment company organized as a Delaware business trust on December 29,
1994.
THE FUND IS GOVERNED BY A BOARD OF TRUSTEES which is responsible for
protecting the interests of shareholders. The trustees are experienced
executives who meet throughout the year to oversee the fund's activities,
review contractual arrangements with companies that provide services to the
fund, and review the fund's performance. The majority of trustees are not
otherwise affiliated with Fidelity.
THE FUND MAY HOLD SPECIAL MEETINGS AND MAIL PROXY MATERIALS. These meetings
may be called to elect or remove trustees, change fundamental policies,
approve a management contract, or for other purposes. Shareholders not
attending these meetings are encouraged to vote by proxy.  The transfer
agent will mail proxy materials in advance, including a voting card and
information about the proposals to be voted on. The number of votes you are
entitled to is based upon the dollar value of your investment.
FMR AND ITS AFFILIATES
Fidelity Investments is one of the largest investment management
organizations in the United States and has its principal business address
at 82 Devonshire Street, Boston, Massachusetts 02109. It includes a number
of different subsidiaries and divisions which provide a variety of
financial services and products. The fund employs various Fidelity
companies to perform activities required for its operation.
The fund is managed by FMR, which handles the fund's business affairs. FMR
Texas Inc. (FMR Texas), located in Irving, Texas, has primary
responsibility for providing investment management services.
As of August 31, 1995, FMR advised funds having approximately    22    
million shareholder accounts with a total value of more than    $328    
billion.
Fidelity investment personnel may invest in securities for their own
account pursuant to a code of ethics that establishes procedures for
personal investing and restricts certain transactions.
Fidelity Distributors Corporation (FDC) distributes and markets Fidelity's
funds and services. Fidelity Investments Institutional Operations Company
(FIIOC) performs transfer agent servicing functions for the fund.
FMR Corp. is the ultimate parent company of FMR and FMR Texas.  Members of
the Edward C. Johnson 3d family are the predominant owners of a class of
shares of common stock representing approximately 49% of the voting power
of FMR Corp.  Under the Investment Company Act of 1940 (the 1940 Act),
control of a company is presumed where one individual or group of
individuals owns more than 25% of the voting stock of that company;
therefore, the Johnson family may be deemed under the 1940 Act to form a
controlling group with respect to FMR Corp.
To carry out the fund's transactions, FMR may use its broker-dealer
affiliates and other firms that sell fund shares, provided that the fund
receives services and commission rates comparable to those of other
broker-dealers.
INVESTMENT PRINCIPLES AND RISKS
The fund invests in high quality, U.S. dollar-denominated money market
instruments of domestic and foreign issuers.  Under normal conditions, the
fund intends to invest more than 25% of its total assets in obligations of
institutions in the financial services industry.
When you sell your shares, they should be worth the same amount as when you
bought them. Of course, there is no guarantee that the fund will maintain a
stable $1.00 share price. The fund follows industry-standard guidelines on
the quality and maturity of its investments, which are designed to help
maintain a stable $1.00 share price. The fund will purchase only
high-quality securities that FMR believes present minimal credit risks and
will observe maturity restrictions on securities it buys. In general,
securities with longer maturities are more vulnerable to price changes,
although they may provide higher yields. It is possible that a major change
in interest rates or a default on the fund's investments could cause its
share price (and the value of your investment) to change.
The fund earns income at current money market rates. It stresses
preservation of capital, liquidity   , and income     and does not seek the
higher yields or capital appreciation that more aggressive investments may
provide. The fund's yield will vary from day to day and generally reflects
current short-term interest rates and other market conditions.
SECURITIES AND INVESTMENT PRACTICES
The following pages contain more detailed information about types of
instruments in which the fund may invest, strategies FMR may employ in
pursuit of the fund's investment objective, and a summary of related risks.
Any restrictions listed supplement those discussed earlier in this section.
A complete listing of the fund's limitations and more detailed information
about the fund's investments are contained in the fund's SAI. Policies and
limitations are considered at the time of purchase; the sale of instruments
is not required in the event of a subsequent change in circumstances.
FMR may not buy all of these instruments or use all of these techniques
unless it believes that they are consistent with the fund's investment
objective and policies and that doing so will help the fund achieve its
goal. Current holdings and recent investment strategies are described in
the fund's financial reports, which are sent to shareholders twice a year.

the appropriate number listed on page .
MONEY MARKET SECURITIES are high-quality, short-term obligations issued by
the U.S. Government, corporations, financial institutions, and other
entities.  These obligations may carry fixed, variable, or floating
interest rates.  A security's credit may be enhanced by a bank, insurance
company, or other entity.  Some money market securities employ a trust or
other similar structure to modify the maturity, price characteristics, or
quality of financial assets so that they are eligible investments for money
market funds.  If the structure does not perform as intended, adverse tax
or investment consequences may result.  
U.S. GOVERNMENT MONEY MARKET SECURITIES are short-term debt obligations
issued or guaranteed by the U.S. Treasury or by an agency or
instrumentality of the U.S. Government. Not all U.S. Government securities
are backed by the full faith and credit of the United States. For example,
securities issued by the Federal Farm Credit Bank or by the Federal
National Mortgage Association are supported by the instrumentality's right
to borrow money from the U.S. Treasury under certain circumstances.
However, securities issued by the Financing Corporation are supported only
by the credit of the entity that issued them.
FOREIGN SECURITIES may involve different risks than domestic securities,
including risks relating to the political and economic conditions of the
foreign country involved, which could affect the payment of principal or
interest.  Issuers of foreign securities include foreign governments,
corporations, and banks.
RESTRICTION: The fund may not invest in foreign securities unless they are
denominated in U.S. dollars.
ASSET-BACKED SECURITIES include interests in pools of mortgages, loans,
receivables, or other assets. Payment of principal and interest may be
largely dependent upon the cash flows generated by the assets backing the
securities.
VARIABLE AND FLOATING RATE SECURITIES have interest rates that are
periodically adjusted either at specific intervals or whenever a benchmark
rate changes. These interest rate adjustments are designed to help
stabilize the security's price.
STRIPPED SECURITIES are the separate income or principal components of a
debt security. Their risks are similar to those of other money market
securities, although they may be more volatile.
REPURCHASE AGREEMENTS. In a repurchase agreement, the fund buys a security
at one price and simultaneously agrees to sell it back at a higher price.
Delays or losses could result if the other party to the agreement defaults
or becomes insolvent. 
REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the fund
temporarily transfers possession of a portfolio instrument to another party
in return for cash. This could increase the risk of fluctuation in the
fund's yield or in the market value of its assets.
OTHER MONEY MARKET SECURITIES may include commercial paper, certificates of
deposit, bankers' acceptances, and time deposits.
PUT FEATURES entitle the holder to put (sell back) a security to the issuer
or a financial intermediary. In exchange for this benefit, the fund may pay
periodic fees or accept a lower interest rate. The credit quality of the
investment may be affected by the creditworthiness of the put provider.
Demand features, standby commitments, and tender options are types of put
features.
ILLIQUID AND RESTRICTED SECURITIES. Some investments may be determined by
FMR, under the supervision of the Board of Trustees, to be illiquid, which
means that they may be difficult to sell promptly at an acceptable price.
The sale of some illiquid securities, and some other securities, may be
subject to legal restrictions. Difficulty in selling securities may result
in a loss or may be costly to the fund.
RESTRICTION: The fund may not purchase a security if, as a result, more
than 10% of its net assets would be invested in illiquid securities. 
WHEN-ISSUED AND DELAYED-DELIVERY TRANSACTIONS are trading practices in
which payment and delivery for the securities take place at a future date.
The market value of a security could change during this period, which could
affect the market value of the fund's assets. 
FINANCIAL SERVICES INDUSTRY. Companies in the financial services industry
are subject to various risks related to that industry, such as government
regulation, changes in interest rates, and exposure on loans, including
loans to foreign borrowers. If a fund invests substantially in this
industry, its performance may be affected by conditions affecting the
industry.
DIVERSIFICATION. Diversifying a fund's investment portfolio can reduce the
risks of investing. This may include limiting the amount of money invested
in any one issuer or, on a broader scale, in any one industry.  Economic,
business, or political changes can affect all securities of a similar type.
RESTRICTIONS: The fund may not invest more than 5% of its total assets
   in     any    one     issuer, except that the fund may invest up to 25%
of its    tota    l assets in the highest quality securities of a single
issuer for up to three business days. These limitations do not apply to
U.S. Government securities.
BORROWING. The fund may borrow from banks or from other funds advised by
FMR, or through reverse repurchase agreements, and may make additional
investments while borrowings are outstanding.
RESTRICTION: The fund may borrow only for temporary or emergency purposes,
or engage in reverse repurchase agreements, but not in an amount exceeding
331/3% of its total assets.
LENDING.  The fund may lend money to other funds advised by FMR.
RESTRICTION: Loans, in the aggregate, may not exceed 331/3% of the fund's
total assets.
FUNDAMENTAL INVESTMENT POLICIES AND RESTRICTIONS
Some of the policies and restrictions discussed on the preceding pages are
fundamental, that is, subject to change only by shareholder approval. The
following paragraphs restate all those that are fundamental. All policies
stated throughout this prospectus, other than those identified in the
following paragraphs, can be changed without shareholder approval. 
The fund seeks to obtain as high a level of current income as is consistent
with the preservation of capital and liquidity by investing in money market
instruments.
   Under normal conditions, the fund intends to invest more than 25% of its
total assets in obligations of institutions in the financial services
industry.    
The fund may borrow only for temporary or emergency purposes, or engage in
reverse repurchase agreements, but not in an amount exceeding 331/3% of its
total assets.
Loans, in the aggregate, may not exceed 331/3% of the fund's total assets.
BREAKDOWN OF EXPENSES
Like all mutual funds, the fund pays fees related to its daily operations.
Expenses paid out of the fund's assets are reflected in its share price or
dividends; they are neither billed directly to shareholders nor deducted
from shareholder accounts.
FMR may, from time to time, agree to reimburse the fund for management fees
above a specified limit. Reimbursement arrangements, which may be
terminated at any time without notice, can decrease the fund's expenses and
boost its performance.
MANAGEMENT FEE
The management fee is calculated and paid to FMR every month. FMR pays all
of the expenses of the fund with limited exceptions. The annual management
fee is 0.42% of the fund's average net assets.
FMR HAS A SUB-ADVISORY AGREEMENT with FMR Texas, which has primary
responsibility for providing investment management for the fund, while FMR
retains responsibility for providing the fund with other management
services. FMR pays FMR Texas 50% of its management fee (before expense
reimbursements) for these services. FMR paid FMR Texas    0.21%     of the
fund's average net assets for fiscal 1995.
OTHER EXPENSES
FIIOC performs transfer agency, dividend disbursing and shareholder
servicing functions for the fund. Fidelity Service Co. (FSC) calculates the
net asset value per share (NAV) and dividends for the fund    and
    maintains the fund's general accounting records.
These expenses are paid by FMR pursuant to its management contract.
The fund has adopted a DISTRIBUTION AND SERVICE PLAN. This plan recognizes
that FMR may use its resources, including management fees, to pay expenses
associated with the sale of fund shares. This may include    reimbursing
FDC for     payments to third parties, such as banks or broker-dealers,
that provide shareholder support services or engage in the sale of the
fund's shares. The Board of Trustees has not authorized such payments.
The fund also pays other expenses, such as brokerage fees and commissions,
taxes, and the compensation of trustees who are not affiliated with
Fidelity.

INFORMATION SERVICES
STATEMENTS AND REPORTS that the transfer agent sends to you include the
following:
(small solid bullet) Confirmation statements (after every transaction,
except a reinvestment, that affects your account balance or your account
registration)
(small solid bullet) Account statements (quarterly)

SUB-ACCOUNTING AND SPECIAL SERVICES. Special processing has been arranged
with FIIOC for institutions that wish to open multiple accounts (a master
account and sub-accounts). You may be required to enter into a separate
agreement with FIIOC. Charges for these services, if any, will be
determined based on the level of services to be rendered.
   SHAREHOLDER AND ACCOUNT POLICIES    
 
 
DIVIDENDS, CAPITAL GAINS, AND TAXES
The fund distributes substantially all of its net investment income and
capital gains, if any, to shareholders each year. Income dividends are
declared daily and paid monthly.
Income dividends declared are accrued daily throughout the month and are
   normally     distributed on the first business day of the following
month. Based on prior approval of the fund, dividends relating to shares
redeemed during the month can be distributed on the day of redemption. The
fund reserves the right to limit this service. Shareholders may elect to
receive dividend distributions in cash.
DISTRIBUTION OPTIONS
When you open an account, specify on your account application how you want
to receive your distributions. The fund offers    two     options:
1. REINVESTMENT OPTION. Your dividend and capital gain distributions, if
any, will be automatically reinvested in additional shares of the fund. If
you do not indicate a choice on your application, you will be assigned this
option.
   2.     CASH OPTION. You will be sent a check for your dividend and
capital gain distributions, if any.
For retirement accounts, all distributions are automatically reinvested.
When you are over 59 years old, you can receive distributions in cash.
Dividends will be reinvested at the fund's NAV on the last day of the
month. Capital gain distributions, if any, will be reinvested at the NAV as
of the record date of the distribution. The mailing of distribution checks
will begin within seven days.
TAXES
As with any investment, you should consider how your investment in the fund
will be taxed. If your account is not a tax-deferred retirement account,
you should be aware of these tax implications.
TAXES ON DISTRIBUTIONS. Distributions are subject to federal income tax,
and may also be subject to state or local taxes. If you live outside the
United States, your distributions could also be taxed by the country in
which you reside. Your distributions are taxable when they are paid,
whether you take them in cash or reinvest them. However, distributions
declared in December and paid in January are taxable as if they were paid
on December 31.
For federal tax purposes, the fund's income and short-term capital gain
distributions are taxed as dividends; long-term capital gain distributions,
if any, are taxed as long-term capital gains.
Every January, the transfer agent will send you and the Internal Revenue
Service (IRS) a statement showing the taxable distributions paid to you in
the previous year.
There are tax requirements that all funds must follow in order to avoid
federal taxation. In its effort to adhere to these requirements, the fund
may have to limit its investment activity in some types of instruments. 
TRANSACTION DETAILS
THE FUND IS OPEN FOR BUSINESS and its NAV is normally calculated each day
the New York Stock Exchange (NYSE) is open. The following holiday closings
have been scheduled for 199   6    : New Year's Day, Washington's Birthday,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day. Although FMR expects the same holiday schedule to be
observed in the future, the NYSE may modify its holiday schedule at any
time. On any day that the NYSE closes early, the principal government
securities markets close early (such as on days in advance of holidays
generally observed by participants in such markets), or as permitted by the
SEC, the right is reserved to advance the time on that day by which
purchase and redemption orders must be received. 
To the extent that portfolio securities are traded in other markets on days
when the NYSE is closed, the fund's NAV may be affected on days when
investors do not have access to the fund to purchase or redeem shares.
Certain Fidelity funds may follow different holiday closing schedules.
THE FUND'S NAV is the value of a single share. The NAV is computed by
adding the value of the fund's investments, cash, and other assets,
subtracting its liabilities, and dividing the result by the number of
shares outstanding. The fund values its portfolio securities on the basis
of amortized cost. This method minimizes the effect of changes in a
security's market value and helps the fund maintain a stable $1.00 share
price.
THE FUND'S OFFERING PRICE (price to buy one share) and REDEMPTION PRICE
(price to sell one share) are its NAV. 
WHEN YOU SIGN YOUR ACCOUNT APPLICATION, you will be asked to certify that
your social security or taxpayer identification number is correct and that
you are not subject to 31% backup withholding for failing to report income
to the IRS. If you violate IRS regulations, the IRS can require the fund to
withhold 31% of your taxable distributions and redemptions.
YOU MAY INITIATE MANY TRANSACTIONS BY TELEPHONE. Fidelity may only be
liable for losses resulting from unauthorized transactions if it does not
follow reasonable procedures designed to verify the identity of the caller.
Fidelity will request personalized security codes or other information, and
may also record calls. You should verify the accuracy of the confirmation
statements immediately after receipt. If you do not want the ability to
redeem and exchange by telephone, call Fidelity Client Services at the
appropriate number listed on page  for instructions. Additional
documentation may be required from corporations, associations and certain
fiduciaries.
IF YOU ARE UNABLE TO REACH FIDELITY BY PHONE (for example, during periods
of unusual market activity), consider placing your order by mail. 
THE FUND RESERVES THE RIGHT TO SUSPEND THE OFFERING OF SHARES for a period
of time. The fund also reserves the right to reject any specific purchase
order, including certain purchases by exchange. See "Exchange Restrictions"
on page . Purchase orders may be refused if, in FMR's opinion, they would
disrupt management of the fund.
TO ALLOW FMR TO MANAGE THE FUND MOST EFFECTIVELY, you are urged to initiate
all trades as early in the day as possible and to notify Fidelity Client
Services in advance of large transactions.
WHEN YOU PLACE AN ORDER TO BUY SHARES, your shares will be purchased at the
next NAV calculated after your order is received and accepted by the
transfer agent. Note the following: 
(small solid bullet) All of your purchases must be made in U.S. dollars and
checks must be drawn on U.S. banks. 
(small solid bullet) Fidelity does not accept cash. 
(small solid bullet) When making a purchase with more than one check, each
check must have a value of at least $50.
(small solid bullet) The fund reserves the right to limit the number of
checks processed at one time.
(small solid bullet) If your check does not clear, your purchase will be
canceled and you could be liable for any losses or fees the fund or
Fidelity has incurred.
Net interest income for dividend purposes is determined by FSC on a daily
basis and shall be payable to shareholders of record at the time of its
declaration (including, for this purpose, holders of shares purchased, but
excluding holders of shares redeemed, on that day).
Shares purchased begin to earn income dividends on the following business
day.
WHEN YOU PLACE AN ORDER TO SELL SHARES, your shares will be sold at the
next NAV calculated after your order is received and accepted by the
transfer agent. Note the following: 
   (small solid bullet) Shares redeemed receive the dividends declared on
the day of redemption.    
(small solid bullet) The fund may withhold redemption proceeds until it is
reasonably assured that investments    credited to your account have been
received and     collected.
When the NYSE is closed (or when trading is restricted) for any reason
other than its customary weekend or holiday closings, or under any
emergency circumstances as determined by the SEC to merit such action, the
fund may suspend redemption or postpone payment dates. In cases of
suspension of the right of redemption, the request for redemption may
either be withdrawn or payment may be made based on the NAV next determined
after the termination of the suspension.
IF YOUR ACCOUNT BALANCE FALLS BELOW $100,000 due to redemption, the account
may be closed and the proceeds may be mailed to your address of record. You
will be given 30 days' notice that your account will be closed unless it is
increased to the minimum.
FIDELITY MAY CHARGE A FEE FOR SPECIAL SERVICES, such as providing
historical account documents, that are beyond the normal scope of its
services. 
EXCHANGE RESTRICTIONS
As a shareholder you have the privilege of exchanging shares of the fund
for shares of other Fidelity funds.
An exchange involves the redemption of all or a portion of the shares of
one fund and the purchase of shares of another fund.
BY TELEPHONE. Exchanges may be requested on any day the fund is open for
business by calling Fidelity Client Services at the appropriate number
listed on page        .
BY MAIL. You may exchange shares on any business day by submitting written
instructions with an authorized signature which is on file for that
account. Written requests for exchanges should contain the fund name,
account number, the number of shares to be redeemed, and the name of the
fund to be purchased. Written requests for exchange should be mailed to
Fidelity Client Services at the address    shown     on page .
WHEN YOU PLACE AN ORDER TO EXCHANGE SHARES, shares will be redeemed at the
next determined NAV after your order is received and accepted by the
transfer agent. Shares of the fund to be acquired will be purchased at its
next determined NAV after redemption proceeds are made available. You
should note that, under certain circumstances, the fund may take up to
seven days to make redemption proceeds available for the exchange purchase
of shares of another fund. In addition, please note the following:
(small solid bullet) Exchanges will not be permitted until a completed and
signed account application is on file. 
(small solid bullet) The fund you are exchanging into must be registered
for sale in your state.
(small solid bullet) You may only exchange between accounts that are
registered in the same name, address, and taxpayer identification number.
(small solid bullet) Before exchanging into a fund, read its prospectus.
(small solid bullet) You will earn dividends in the acquired fund in
accordance with the fund's customary policy, normally on the day the
exchange request is received.
(small solid bullet) If you exchange into a fund with a sales charge, you
pay the percentage difference between that fund's sales charge and any
sales charge you have already paid in connection with the shares you are
exchanging. This may not apply if you are investing through a tax-saving
retirement plan.
(small solid bullet) Exchanges may have tax consequences for you.
(small solid bullet) Currently, there is no limit on the number of
exchanges out of the fund, nor are there any administrative or redemption
fees applicable to exchanges out of the fund. 
(small solid bullet) The fund reserves the right to refuse exchange
purchases by any person or group if, in FMR's judgment, the fund would be
unable to invest the money effectively in accordance with its investment
objective and policies, or would otherwise potentially be adversely
affected.
(small solid bullet) Your exchanges may be restricted or refused if the
fund receives or anticipates simultaneous orders affecting significant
portions of the fund's assets. In particular, a pattern of exchanges that
coincides with a "market timing" strategy may be disruptive to the fund.
Although the fund will attempt to give you prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time. The
fund reserves the right to terminate or modify the exchange privilege in
the future. 
OTHER FUNDS MAY HAVE DIFFERENT EXCHANGE RESTRICTIONS, and may impose
administrative fees of up to $7.50 and redemption fees of up to 1.50% on
exchanges. Check each fund's prospectus for details.
No dealer, sales representative or any other person has been authorized to
give any information or to make any representations, other than those
contained in this Prospectus and in the related SAI, in connection with the
offer contained in this Prospectus. If given or made, such other
information or representations must not be relied upon as having been
authorized by the fund or FDC. This Prospectus and the related SAI do not
constitute an offer by the fund or by FDC to sell or to buy shares of the
fund to any person to whom it is unlawful to make such offer.

INVESTMENT POLICIES AND LIMITATIONS
The following policies and limitations supplement those set forth in the
Prospectus. Unless otherwise noted, whenever an investment policy or
limitation states a maximum percentage of the fund's assets that may be
invested in any security or other asset, or sets forth a policy regarding
quality standards, such standard or percentage limitation will be
determined immediately after and as a result of the fund's acquisition of
such security or other asset. Accordingly, any subsequent change in values,
net assets or other circumstances will not be considered when determining
whether the investment complies with the fund's investment policies and
limitations.
The fund's fundamental investment policies and limitations cannot be
changed without approval by a "majority of the outstanding voting
securities" (as defined in the Investment Company Act of 1940 (1940 Act))
of the fund. However, except for the fundamental investment limitations
listed below, the investment policies and limitations described in this SAI
are not fundamental and may be changed without shareholder approval. THE
FOLLOWING ARE THE FUND'S FUNDAMENTAL INVESTMENT LIMITATIONS SET FORTH IN
THEIR ENTIRETY. THE FUND MAY NOT:
(1)  with respect to 75% of the fund's total assets, purchase the
securities of any issuer (other than securities issued or guaranteed by the
U.S Government or any of its agencies or instrumentalities) if, as a
result, (a) more than 5% of the fund's total assets would be invested in
the securities of that issuer; or (b) the fund would hold more than 10% of
the outstanding voting securities of that issuer;
(2) issue senior securities, except as permitted under the Investment
Company Act of 1940;
(3)  borrow money, except that the fund may (i) borrow money for temporary
or emergency purposes (not for leveraging or investment), and (ii) engage
in reverse repurchase agreements for any purpose; provided that (i) and
(ii) in combination do not exceed 33 1/3% of the fund's total assets
(including the amount borrowed) less liabilities (other than borrowings).
Any borrowings that come to exceed this amount will be reduced within three
days (not including Sundays and holidays) to the extent necessary to comply
with the 33 1/3% limitation;
(4) underwrite securities issued by others, except to the extent that the
fund may be considered an underwriter within the meaning of the Securities
Act of 1933 in the disposition of restricted securities;
(5)  purchase the securities of any issuer (other than obligations issued
or guaranteed by the government of the United States, its agencies or
instrumentalities) if, as a result, more than 25% of the fund's total
assets (taken at current value) would be invested in the securities of
issuers having their principal business activities in the same industry,
except that the fund intends to invest more than 25% of total assets in
obligations of institutions in the financial services industry. Neither
finance companies as a group or utility companies as a group are considered
a single industry for purposes of this policy;
(6)  purchase or sell real estate unless acquired as a result of ownership
of securities or other instruments (but this shall not prevent the fund
from investing in securities or other instruments backed by real estate or
securities of companies engaged in the real estate business); 
(7)  purchase or sell physical commodities unless acquired as a result of
ownership of securities or other instruments; or
(8)  lend any security or make any other loan if, as a result, more than 33
1/3% of its total assets would be lent to other parties, but this
limitation does not apply to purchases of debt securities or to repurchase
agreements.
(9) The fund may, notwithstanding any other fundamental investment policy
or limitation, invest all of its assets in the securities of a single
open-end management investment company with substantially the same
fundamental investment objective, policies and limitations as the fund.
THE FOLLOWING LIMITATIONS ARE NOT FUNDAMENTAL AND MAY BE CHANGED WITHOUT
SHAREHOLDER APPROVAL.
(i) The fund does not currently intend to purchase a security (other than a
security issued or guaranteed by the U.S. Government or any of its agencies
or instrumentalities) if, as a result, more than 5% of its total assets
would be invested in the securities of a single issuer; provided that the
fund may invest up to 25% of its total assets in the first tier securities
of a single issuer for up to three business days.
(ii)  The fund may borrow money only (a) from a bank or from a registered
investment company or portfolio for which FMR or an affiliate serves as
investment adviser or (b) by engaging in reverse repurchase agreements with
any party. The fund will not purchase any security while borrowings
(excluding reverse repurchase agreements) representing more than 5% of its
total assets are outstanding. The fund will not borrow from other funds
advised by FMR or its affiliates if total outstanding borrowings
immediately after such borrowing would exceed 15% of the fund's total
assets.
(iii) The fund does not currently intend to sell securities short, unless
it owns or has the right to obtain securities equivalent in kind and amount
to the securities sold short, and provided that transactions in futures
contracts and options are not deemed to constitute selling securities
short.
(iv) The fund does not currently intend to purchase securities on margin,
except that the fund may obtain such short-term credits as are necessary
for the clearance of transactions, and provided that margin payments in
connection with futures contracts and options on futures contracts shall
not constitute purchasing securities on margin.
(v) The fund does not currently intend to purchase any security if, as a
result, more than 10% of its net assets would be invested in securities
that are deemed to be illiquid because they are subject to legal or
contractual restrictions on resale or because they cannot be sold or
disposed of in the ordinary course of business at approximately the prices
at which they are valued.
(vi) The fund does not currently intend to purchase or sell futures
contracts or call options. This limitation does not apply to options
attached to, or acquired or traded together with, their underlying
securities, and does not apply to securities that incorporate features
similar to options or futures contracts.
(vii) The fund does not currently intend to invest in oil, gas, or other
mineral exploration or development programs or leases.
(viii) The fund does not currently intend to lend assets other than
securities to other parties, except by lending money (up to 10% of the
fund's net assets) to a registered investment company or portfolio for
which FMR or an affiliate serves as investment adviser. (This limitation
does not apply to purchases of debt securities or to repurchase
agreements.)
(ix) The fund does not currently intend to (a) purchase securities of other
investment companies, except in the open market where no commission except
the ordinary broker's commission is paid, or (b) purchase or retain
securities issued by other open-end investment companies. Limitations (a)
and (b) do not apply to securities received as dividends, through offers of
exchange, or as a result of a reorganization, consolidation, or merger.
(x) The fund does not currently intend to invest all of its assets in the
securities of a single open-end management investment company with
substantially the same fundamental investment objective, policies, and
limitations as the fund.
For the fund's policies on quality and maturity, see the section entitled
"Quality and Maturity" on page .
AFFILIATED BANK TRANSACTIONS. The fund may engage in transactions with
financial institutions that are, or may be considered to be, "affiliated
persons" of the fund under the 1940 Act. These transactions may include
repurchase agreements with custodian banks; short-term obligations of, and
repurchase agreements with, the 50 largest U.S. banks (measured by
deposits); municipal securities; U.S. Government securities with affiliated
financial institutions that are primary dealers in these securities;
short-term currency transactions; and short-term borrowings. In accordance
with exemptive orders issued by the Securities and Exchange Commission
(SEC), the Board of Trustees has established and periodically reviews
procedures applicable to transactions involving affiliated financial
institutions.
ASSET-BACKED SECURITIES include pools of mortgages, loans, receivables or
other assets. Payment of principal and interest may be largely dependent
upon the cash flows generated by the assets backing the securities and, in
certain cases, supported by letters of credit, surety bonds, or other
credit enhancements. The value of asset-backed securities may also be
affected by the creditworthiness of the servicing agent for the pool, the
originator of the loans or receivables, or the entities providing the
credit support.
DELAYED-DELIVERY TRANSACTIONS. The fund may buy and sell securities on a
delayed-delivery or when-issued basis. These transactions involve a
commitment by the fund to purchase or sell specific securities at a
predetermined price or yield, with payment and delivery taking place after
the customary settlement period for that type of security. Typically, no
interest accrues to the purchaser until the security is delivered.
When purchasing securities on a delayed-delivery basis, the fund assumes
the rights and risks of ownership, including the risk of price and yield
fluctuations. Because the fund is not required to pay for securities until
the delivery date, these risks are in addition to the risks associated with
the fund's other investments. If the fund remains substantially fully
invested at a time when delayed-delivery purchases are outstanding, the
delayed-delivery purchases may result in a form of leverage. When
delayed-delivery purchases are outstanding, the fund will set aside
appropriate liquid assets in a segregated custodial account to cover its
purchase obligations. When the fund has sold a security on a
delayed-delivery basis, the fund does not participate in further gains or
losses with respect to the security. If the other party to a
delayed-delivery transaction fails to deliver or pay for the securities,
the fund could miss a favorable price or yield opportunity, or could suffer
a loss.
The fund may renegotiate delayed-delivery transactions after they are
entered into, and may sell underlying securities before they are delivered,
which may result in capital gains or losses.
DOMESTIC AND FOREIGN ISSUERS. Investments may be made in U.S.
dollar-denominated time deposits, certificates of deposit, and bankers'
acceptances of U.S. banks and their branches located outside of the United
States, U.S. branches and agencies of foreign banks, and foreign branches
of foreign banks. The fund may also invest in U.S. dollar-denominated
securities issued or guaranteed by other U.S. or foreign issuers, including
U.S. and foreign corporations or other business organizations, foreign
governments, foreign government agencies or instrumentalities, and U.S. and
foreign financial institutions, including savings and loan institutions,
insurance companies, mortgage bankers, and real estate investment trusts,
as well as banks.
The obligations of foreign branches of U.S. banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation and by governmental
regulation. Payment of interest and principal on these obligations may also
be affected by governmental action in the country of domicile of the branch
(generally referred to as sovereign risk). In addition, evidence of
ownership of portfolio securities may be held outside of the United States
and the fund may be subject to the risks associated with the holding of
such property overseas. Various provisions of federal law governing the
establishment and operation of U.S. branches do not apply to foreign
branches of U.S. banks.
Obligations of U.S. branches and agencies of foreign banks may be general
obligations of the parent bank in addition to the issuing branch, or may be
limited by the terms of a specific obligation and by federal and state
regulation, as well as by governmental action in the country in which the
foreign bank has its head office.
Obligations of foreign issuers involve certain additional risks. These
risks may include future unfavorable political and economic developments,
withholding taxes, seizures of foreign deposits, currency controls,
interest limitations, or other governmental restrictions that might affect
payment of principal or interest, or the ability to honor a credit
commitment. Additionally, there may be less public information available
about foreign entities. Foreign issuers may be subject to less governmental
regulation and supervision than U.S. issuers. Foreign issuers also
generally are not bound by uniform accounting, auditing, and financial
reporting requirements comparable to those applicable to U.S. issuers.
ILLIQUID INVESTMENTS are investments that cannot be sold or disposed of in
the ordinary course of business at approximately the prices at which they
are valued. Under the supervision of the Board of Trustees, FMR determines
the liquidity of the fund's investments and, through reports from FMR, the
Board monitors investments in illiquid instruments. In determining the
liquidity of the fund's investments, FMR may consider various factors,
including (1) the frequency of trades and quotations, (2) the number of
dealers and prospective purchasers in the marketplace, (3) dealer
undertakings to make a market, (4) the nature of the security (including
any demand or tender features), and (5) the nature of the marketplace for
trades (including the ability to assign or offset the fund's rights and
obligations relating to the investment).
Investments currently considered by the fund to be illiquid include
repurchase agreements not entitling the holder to payment of principal and
interest within seven days. Also, FMR may determine some restricted
securities and time deposits to be illiquid. 
In the absence of market quotations, illiquid investments are valued for
purposes of monitoring amortized cost valuation at fair value as determined
in good faith by a committee appointed by the Board of Trustees. If through
a change in values, net assets, or other circumstances, the fund were in a
position where more than 10% of its net assets was invested in illiquid
securities, it would seek to take appropriate steps to protect liquidity.
INTERFUND BORROWING AND LENDING PROGRAM. Pursuant to an exemptive order
issued by the SEC, the fund has received permission to lend money to, and
borrow money from, other funds advised by FMR or its affiliates. Interfund
loans and borrowings normally extend overnight, but can have a maximum
duration of seven days. Loans may be called on one day's notice. A fund
will lend through the program only when the returns are higher than those
available from other short-term instruments (such as repurchase
agreements), and will borrow through the program only when the costs are
equal to or lower than the cost of bank loans. A fund may have to borrow
from a bank at a higher interest rate if an interfund loan is called or not
renewed. Any delay in repayment to a lending fund could result in a lost
investment opportunity or additional borrowing costs.
MONEY MARKET SECURITIES are high-quality, short-term obligations. Some
money market securities employ a trust or other similar structure to modify
the maturity, price characteristics, or quality of financial assets. For
example, put features can be used to modify the maturity of a security, or
interest rate adjustment features can be used to enhance price stability.
If the structure does not perform as intended, adverse tax or investment
consequences may result. Neither the Internal Revenue Service (IRS) nor any
other regulatory authority has ruled definitively on certain legal issues
presented by structured securities. Future tax or other regulatory
determinations could adversely affect the value, liquidity, or tax
treatment of the income received from these securities or the nature and
timing of distributions made by the fund.
MUNICIPAL SECURITIES are issued to raise money for a variety of public or
private purposes, including general financing for state and local
governments, or financing for specific projects or public facilities. They
may be issued in anticipation of future revenues, and may be backed by the
full taxing power of a municipality, the revenues from a specific project,
or the credit of a private organization. The value of some or all municipal
securities may be affected by uncertainties in the municipal market related
to legislation or litigation involving the taxation of municipal securities
or the rights of municipal securities holders. The fund may own a municipal
security directly or through a participation interest.
PUT FEATURES entitle the holder to sell a security back to the issuer or a
third party at any time or at specified intervals. They are subject to the
risk that the put provider is unable to honor the put feature (purchase the
security). Put providers often support their ability to buy securities on
demand by obtaining letters of credit or other guarantees from other
entities. Demand features, standby commitments, and tender options are
types of put features.
QUALITY AND MATURITY. Pursuant to procedures adopted by the Board of
Trustees, the fund may purchase only high-quality securities that FMR
believes present minimal credit risks. To be considered high quality, a
security must be rated in accordance with applicable rules in one of the
two highest categories for short-term securities by at least two nationally
recognized rating services (or by one, if only one rating service has rated
the security); or, if unrated, judged to be of equivalent quality by FMR.
High-quality securities are divided into "first tier" and "second tier"
securities. First tier securities are those deemed to be in the highest
rating category (e.g., Standard & Poor's A-1), and second tier securities
are those deemed to be in the second highest rating category (e.g.,
Standard & Poor's A-2). Split-rated securities may be determined to be
either first tier or second tier based on applicable regulations.
The fund may not invest more than 5% of its total assets in second tier
securities. In addition, the fund may not invest more than 1% of its total
assets or $1 million (whichever is greater) in the second tier securities
of a single issuer.
The fund currently intends to limit its investments to securities with
remaining maturities of 397 days or less, and to maintain a dollar-weighted
average maturity of 90 days or less. When determining the maturity of a
security, the fund may look to an interest rate reset or demand feature.
REPURCHASE AGREEMENTS. In a repurchase agreement, the fund purchases a
security and simultaneously commits to sell that security back to the
original seller at an agreed-upon price. The resale price reflects the
purchase price plus an agreed-upon incremental amount which is unrelated to
the coupon rate or maturity of the purchased security.    To     protect
the fund from the risk that the original seller will not fulfill its
obligation, the securities are held in an account of the fund at a bank,
marked-to-market daily, and maintained at a value at least equal to the
sale price plus the accrued incremental amount. While it does not presently
appear possible to eliminate all risks from these transactions
(particularly the possibility that the value of the underlying security
will be less than the resale price, as well as delays and costs to the fund
in connection with bankruptcy proceedings), it is the fund's current policy
to engage in repurchase agreement transactions with parties whose
creditworthiness has been reviewed and found satisfactory by FMR.
RESTRICTED SECURITIES generally can be sold in privately negotiated
transactions, pursuant to an exemption from registration under the
Securities Act of 1933, or in a registered public offering. Where
registration is required, the fund may be obligated to pay all or part of
the registration expense and a considerable period may elapse between the
time it decides to seek registration and the time it may be permitted to
sell a security under an effective registration statement. If, during such
a period, adverse market conditions were to develop, the fund might obtain
a less favorable price than prevailed when it decided to seek registration
of the security. However, in general, the fund anticipates holding
restricted securities to maturity or selling them in an exempt transaction.
REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the fund
sells a portfolio instrument to another party, such as a bank or a
broker-dealer, in return for cash and agrees to repurchase the instrument
at a particular price and time. While a reverse repurchase agreement is
outstanding, the fund will maintain appropriate liquid assets in a
segregated custodial account to cover its obligation under the agreement.
The fund will enter into reverse repurchase agreements only with parties
whose creditworthiness has been found satisfactory by FMR. Such
transactions may increase fluctuations in the market value of the fund's
assets and may be viewed as a form of leverage.
SHORT SALES    "    AGAINST THE BOX   "    . The fund may sell securities
short when it owns or has the right to obtain securities equivalent in kind
or amount to the securities sold short. Short sales could be used to
protect the net asset value per share (NAV) of the fund in anticipation of
increased interest rates, without sacrificing the current yield of the
securities sold short. If the fund enters into a short sale against the
box, it will be required to set aside securities equivalent in kind and
amount to the securities sold short (or securities convertible or
exchangeable into such securities) and will be required to continue to hold
such securities while the short sale is outstanding. The fund will incur
transaction costs, including interest expenses, in connection with opening,
maintaining and closing short sales against the box.
SOURCES OF CREDIT OR LIQUIDITY    SUPPORT    .    FMR may rely on its
evaluation of the credit of a bank or another entity in determining whether
to purchase a security supported by a letter of credit guarantee, insurance
or other source of credit or liquidity. In evaluating the credit of a
foreign bank or other foreign entities, FMR will consider whether adequate
public information about the entity is available and whether the entity may
be subject to unfavorable political or economic developments, currency
controls, or other government restrictions that might affect its ability to
honor its commitment.    
STRIPPED GOVERNMENT SECURITIES. Stripped securities are created by
separating the income and principal components of a debt instrument and
selling them separately. U.S. Treasury STRIPS (Separate Trading of
Registered Interest and Principal of Securities) are created when the
coupon payments and the principal payment are stripped from an outstanding
Treasury bond by the Federal Reserve Bank. Bonds issued by government
agencies also may be stripped in this fashion.
Privately stripped government securities are created when a dealer deposits
a Treasury security or federal agency security with a custodian for
safekeeping and then sells the coupon payments and principal payment that
will be generated by this security. Proprietary receipts, such as
Certificates of Accrual on Treasury Securities (CATS), Treasury Investment
Growth Receipts (TIGRS), and generic Treasury Receipts (TRs), are stripped
U.S. Treasury securities that are separated into their component parts
through trusts created by their broker sponsors. Bonds issued by the
government agencies also may be stripped in this fashion.
Because of the SEC's views on privately stripped government securities, the
fund must evaluate them as they would non-government securities pursuant to
regulatory guidelines applicable to all money market funds. In addition,
the fund currently intends to purchase only those privately stripped
government securities that have either received the highest rating from two
nationally recognized rating services (or one, if only one has rated the
security), or, if unrated, have been judged to be of equivalent quality by
FMR pursuant to procedures adopted by the Board of Trustees.
VARIABLE AND FLOATING RATE SECURITIES provide for periodic adjustments of
the interest rate paid on the security. Variable rate securities provide
for a specified periodic adjustment in the interest rate, while floating
rate securities have interest rates that change whenever there is a change
in a designated benchmark rate. Some variable or floating rate securities
have put features.
PORTFOLIO TRANSACTIONS
All orders for the purchase or sale of portfolio securities are placed on
behalf of the fund by FMR pursuant to authority contained in the management
contract. FMR has granted investment management authority to the
sub-adviser (see the section entitled "Management Contract"),    and
    the sub-adviser is authorized to place orders for the purchase and sale
of portfolio securities, and will do so in accordance with the policies
described below. FMR is also responsible for the placement of transaction
orders for other investment companies and accounts for which it or its
affiliates act as investment adviser. Securities purchased and sold by the
fund generally will be traded on a net basis (i.e., without commission). In
selecting broker-dealers, subject to applicable limitations of the federal
securities laws, FMR considers various relevant factors, including, but not
limited to, the size and type of the transaction; the nature and character
of the markets for the security to be purchased or sold; the execution
efficiency, settlement capability, and financial condition of the
broker-dealer firm; the broker-dealer's execution services rendered on a
continuing basis; and the reasonableness of any commissions.
The fund may execute portfolio transactions with broker-dealers who provide
research and execution services to the fund or other accounts over which
FMR or its affiliates exercise investment discretion. Such services may
include advice concerning the value of securities; the advisability of
investing in, purchasing, or selling securities; and the availability of
securities or the purchasers or sellers of securities. In addition, such
broker-dealers may furnish analyses and reports concerning issuers,
industries, securities, economic factors and trends, portfolio strategy and
performance of accounts; effect securities transactions, and perform
functions incidental thereto (such as clearance and settlement). FMR
maintains a listing of broker-dealers who provide such services on a
regular basis. However, as many transactions on behalf of the fund are
placed with broker-dealers (including broker-dealers on the list) without
regard to the furnishing of such services, it is not possible to estimate
the proportion of such transactions directed to such broker-dealers solely
because such services were provided. The selection of such broker-dealers
generally is made by FMR (to the extent possible consistent with execution
considerations) based upon the quality of research and execution services
provided.
The receipt of research from broker-dealers that execute transactions on
behalf of the fund may be useful to FMR in rendering investment management
services to the fund or its other clients, and conversely, such research
provided by broker-dealers who have executed transaction orders on behalf
of other FMR clients may be useful to FMR in carrying out its obligations
to the fund. The receipt of such research has not reduced FMR's normal
independent research activities; however, it enables FMR to avoid the
additional expenses that could be incurred if FMR tried to develop
comparable information through its own efforts.
Subject to applicable limitations of the federal securities laws,
broker-dealers may receive commissions for agency transactions that are in
excess of the amount of commissions charged by other broker-dealers in
recognition of their research and execution services. In order to cause the
fund to pay such higher commissions, FMR must determine in good faith that
such commissions are reasonable in relation to the value of the brokerage
and research services provided by such executing broker-dealers, viewed in
terms of a particular transaction or FMR's overall responsibilities to the
fund and its other clients. In reaching this determination, FMR will not
attempt to place a specific dollar value on the brokerage and research
services provided, or to determine what portion of the compensation should
be related to those services.
FMR is authorized to use research services provided by and to place
portfolio transactions with brokerage firms that have provided assistance
in the distribution of shares of the fund or shares of other Fidelity funds
to the extent permitted by law. FMR may use research services provided by
and place agency transactions with Fidelity Brokerage Services, Inc. (FBSI)
and Fidelity Brokerage services (FBS), subsidiaries of FMR Corp., if the
commissions are fair, reasonable, and comparable to commissions charged by
non-affiliated, qualified brokerage firms for similar services. From
September 1992 through December 1994, FBS operated under the name Fidelity
Brokerage Services Limited, Inc. (FBSL). As of January 1995, FBSL was
converted to an unlimited liability company and assumed the name FBS. Prior
to September 4, 1992, FBSL operated under the name Fidelity Portfolio
Services, Ltd. (FPSL) as a wholly owned subsidiary of Fidelity
International Limited (FIL). Edward C. Johnson 3d is Chairman of FIL. Mr.
Johnson 3d, Johnson family members, and various trusts for the benefit of
the Johnson family own, directly or indirectly, more than 25% of the voting
common stock of FIL.
Section 11(a) of the Securities Exchange Act of 1934 prohibits members of
national securities exchanges from executing exchange transactions for
accounts which they or their affiliates manage, unless certain requirements
are satisfied. Pursuant to such requirements, the Board of Trustees has
authorized FBSI to execute portfolio transactions on national securities
exchanges in accordance with approved procedures and applicable SEC rules.
The Trustees periodically review FMR's performance of its responsibilities
in connection with the placement of portfolio transactions on behalf of the
fund and review the commissions paid by the fund over representative
periods of time to determine if they are reasonable in relation to the
benefits to the fund.
   During fiscal 1995, 1994, and 1993, the fund paid no brokerage
commissions.
During fiscal 1995, the fund paid no fees to brokerage firms that provided
research services.    
From time to time the Trustees will review whether the recapture for the
benefit of the fund of some portion of the brokerage commissions or similar
fees paid by the fund on portfolio transactions is legally permissible and
advisable. The fund seeks to recapture soliciting broker-dealer fees on the
tender of portfolio securities, but at present no other recapture
arrangements are in effect. The Trustees intend to continue to review
whether recapture opportunities are available and are legally permissible
and, if so, to determine in the exercise of their business judgment whether
it would be advisable for the fund to seek such recapture.
Although the Trustees and officers of the fund are substantially the same
as those of other funds managed by FMR, investment decisions for the fund
are made independently from those of other funds managed by FMR or accounts
managed by FMR affiliates. It sometimes happens that the same security is
held in the portfolio of more than one of these funds or accounts.
Simultaneous transactions are inevitable when several funds and accounts
are managed by the same investment adviser, particularly when the same
security is suitable for the investment objective of more than one fund or
account.
When two or more funds are simultaneously engaged in the purchase or sale
of the same security, the prices and amounts are allocated in accordance
with procedures believed to be appropriate and equitable for each fund. In
some cases this system could have a detrimental effect on the price or
value of the security as far as the fund is concerned. In other cases,
however, the ability of the fund to participate in volume transactions will
produce better executions and prices for the fund. It is the current
opinion of the Trustees that the desirability of retaining FMR as
investment adviser to the fund outweighs any disadvantages that may be said
to exist from exposure to simultaneous transactions.
VALUATION
Fidelity Service Company (FSC) normally determines the fund's NAV at 4:00
p.m. Eastern time. The valuation of portfolio securities is determined as
of this time for the purpose of computing the fund's NAV.
Portfolio securities and other assets are valued on the basis of amortized
cost. This technique involves initially valuing an instrument at its cost
as adjusted for amortization of premium or accretion of discount rather
than its current market value. The amortized cost value of an instrument
may be higher or lower than the price the fund would receive if it sold the
instrument.
During periods of declining interest rates, the fund's yield based on
amortized cost valuation may be higher than would result if the fund used
market valuations to determine its NAV. The converse would apply during
periods of rising interest rates. 
Valuing the fund's investments on the basis of amortized cost and use of
the term "money market fund" are permitted pursuant to Rule 2a-7 under the
1940 Act. The fund must adhere to certain conditions under Rule 2a-7, as
summarized in the section entitled "Quality and Maturity" on page .
The Board of Trustees oversees FMR's adherence to the provisions of Rule
2a-7 and has established procedures designed to stabilize the fund's NAV at
$1.00. At such intervals as they deem appropriate, the Trustees consider
the extent to which NAV calculated by using market valuations would deviate
from $1.00 per share. If the Trustees believe that a deviation from the
fund's amortized cost per share may result in material dilution or other
unfair results to shareholders, the Trustees have agreed to take such
corrective action, if any, as they deem appropriate to eliminate or reduce,
to the extent reasonably practicable, the dilution or unfair results. Such
corrective action could include selling portfolio instruments prior to
maturity to realize capital gains or losses or to shorten average portfolio
maturity; withholding dividends; redeeming shares in kind; establishing NAV
by using available market quotations; and such other measures as the
Trustees may deem appropriate.
PERFORMANCE
The fund may quote performance in various ways. All performance information
supplied by the fund in advertising is historical and is not intended to
indicate future returns. The fund's yield and total return fluctuate in
response to market conditions and other factors.
YIELD CALCULATIONS. To compute the fund's yield for a period, the net
change in value of a hypothetical account containing one share reflects the
value of additional shares purchased with dividends from the one original
share and dividends declared on both the original share and any additional
shares. The net change is then divided by the value of the account at the
beginning of the period to obtain a base period return. This base period
return is annualized to obtain a current annualized yield. The fund also
may calculate an effective yield by compounding the base period return over
a one-year period. In addition to the current yield, the fund may quote
yields in advertising based on any historical seven-day period. Yields for
the fund are calculated on the same basis as other money market funds, as
required by applicable regulations.
Yield information may be useful in reviewing the fund's performance and in
providing a basis for comparison with other investment alternatives.
However, the fund's yield fluctuates, unlike investments that pay a fixed
interest rate over a stated period of time. When comparing investment
alternatives, investors should also note the quality and maturity of the
portfolio securities of respective investment companies they have chosen to
consider.
Investors should recognize that in periods of declining interest rates the
fund's yield will tend to be somewhat higher than prevailing market rates,
and in periods of rising interest rates the fund's yield will tend to be
somewhat lower. Also, when interest rates are falling, the inflow of net
new money to the fund from the continuous sale of its shares will likely be
invested in instruments producing lower yields than the balance of the
fund's holdings, thereby reducing the fund's current yield. In periods of
rising interest rates, the opposite can be expected to occur.
TOTAL RETURN CALCULATIONS. Total returns quoted in advertising reflect all
aspects of the fund's return, including the effect of reinvesting dividends
and capital gain distributions, and any change in the fund's NAV over a
stated period. Average annual total returns are calculated by determining
the growth or decline in value of a hypothetical historical investment in
the fund over a stated period, and then calculating the annually compounded
percentage rate that would have produced the same result if the rate of
growth or decline in value had been constant over the period. For example,
a cumulative total return of 100% over ten years would produce an average
annual total return of 7.18%, which is the steady annual rate of return
that would equal 100% growth on a compounded basis in ten years. While
average annual total returns are a convenient means of comparing investment
alternatives, investors should realize that the fund's performance is not
constant over time, but changes from year to year, and that average annual
total returns represent averaged figures as opposed to the actual
year-to-year performance of the fund.
In addition to average annual total returns, the fund may quote unaveraged
or cumulative total returns reflecting the simple change in value of an
investment over a stated period. Average annual and cumulative total
returns may be quoted as a percentage or as a dollar amount, and may be
calculated for a single investment, a series of investments, or a series of
redemptions, over any time period. Total returns may be broken down into
their components of income and capital (including capital gains and changes
in share price) in order to illustrate the relationship of these factors
and their contributions to total return. Total returns may be quoted on a
before-tax or after-tax basis. Total returns, yields, and other performance
information may be quoted numerically or in a table, graph, or similar
illustration.

* From December 2, 1988 (commencement of operations).
The following table shows the income and capital elements of the fund's
cumulative total return. The table compares the fund's return to the record
of the Standard & Poor's Composite Index of 500 Stocks (S&P 500), the Dow
Jones Industrial Average (DJIA), and the cost of living (measured by the
Consumer Price Index, or CPI) over the same period. The CPI information is
as of the month end closest to the initial investment date for the fund.
The S&P 500 and DJIA comparisons are provided to show how the fund's total
return compared to the record of a broad average of common stocks and a
narrower set of stocks of major industrial companies, respectively, over
the same period. Of course, since the fund invests in short-term
fixed-income securities, common stocks represent a different type of
investment from the fund. Common stocks generally offer greater growth
potential than the fund, but generally experience greater price volatility,
which means greater potential for loss. In addition, common stocks
generally provide lower income than a fixed-income investment such as the
fund. Figures for the S&P 500 and DJIA are based on the prices of unmanaged
groups of stocks and, unlike the fund's returns, do not include the effect
of paying brokerage commissions or other costs of investing.
During the period from December 2, 1988 (commencement of operations) to
August 31, 1995, a hypothetical $10,000 investment in the fund would have
grown to $   14,529    , assuming all distributions were reinvested. This
was a period of fluctuating interest rates and the figures below should not
be considered representative of the dividend income or capital gain or loss
that could be realized from an investment in the fund today.

* From December 2, 1988 (commencement of operations).
** From month-end closest to initial investment date.
Explanatory Notes: With an initial investment of $10,000 made on December
2, 1988, the net amount invested in fund shares was $10,000. The cost of
the initial investment ($10,000), together with the aggregate cost of
reinvested dividend distributions for the period covered (their cash value
at the time they were reinvested), amounted to $   14,529    . If
distributions had not been reinvested, the amount of distributions earned
from the fund over time would have been smaller, and cash payments
(dividends) for the period would have amounted to $   3,746    . The fund
did not distribute any capital gains during the period. Tax consequences of
different investments have not been factored into the above figures.
PERFORMANCE COMPARISONS. The fund's performance may be compared to the
performance of other mutual funds in general, or to the performance of
particular types of mutual funds. These comparisons may be expressed as
mutual fund rankings prepared by Lipper Analytical Services, Inc. (Lipper),
an independent service located in Summit, New Jersey that monitors the
performance of mutual funds. Lipper generally ranks funds on the basis of
total return, assuming reinvestment of distributions, but does not take
sales charges or redemption fees into consideration, and is prepared
without regard to tax consequences. Lipper may also rank funds based on
yield. In addition to the mutual fund rankings, the fund's performance may
be compared to stock, bond, and money market mutual fund performance
indices prepared by Lipper or other organizations. When comparing these
indices, it is important to remember the risk and return characteristics of
each type of investment. For example, while stock mutual funds may offer
higher potential returns, they also carry the highest degree of share price
volatility. Likewise, money market funds may offer greater stability of
principal, but generally do not offer the higher potential returns
available from stock mutual funds.
From time to time, the fund's performance may also be compared to other
mutual funds tracked by financial or business publications and periodicals.
For example, the fund may quote Morningstar, Inc. in its advertising
materials. Morningstar, Inc. is a mutual fund rating service that rates
mutual funds on the basis of risk-adjusted performance. Rankings that
compare the performance of Fidelity funds to one another in appropriate
categories over specific periods of time may also be quoted in advertising.
The fund may be compared in advertising to Certificates of Deposit (CDs) or
other investments issued by banks or other depository institutions. Mutual
funds differ from bank investments in several respects. For example, the
fund may offer greater liquidity or higher potential returns than CDs, the
fund does not guarantee your principal or your return, and fund shares are
not FDIC insured.
Fidelity may provide information designed to help individuals understand
their investment goals and explore various financial strategies. Such
information may include information about current economic, market, and
political conditions; materials that describe general principles of
investing, such as asset allocation, diversification, risk tolerance, and
goal setting; questionaires designed to help create a personal financial
profile; worksheets used to assess savings needs based on assumed rates of
inflation and hypothetical rates of return; and action plans offering
investment alternatives. Materials may also include discussions of
Fidelity's asset allocation funds and other Fidelity funds, products, and
services.
Ibbotson Associates of Chicago, Illinois (Ibbotson) provides historical
returns of the capital markets in the United States, including common
stocks, small capitalization stocks, long-term corporate bonds,
intermediate-term government bonds, long-term government bonds, Treasury
bills, the U.S. rate of inflation (based on the CPI), and combinations of
various capital markets. The performance of these capital markets is based
on the returns of different indices.
Fidelity funds may use the performance of these capital markets in order to
demonstrate general risk-versus-reward investment scenarios. Performance
comparisons may also include the value of a hypothetical investment in any
of these capital markets. The risks associated with the security types in
any capital market may or may not correspond directly to those of the
funds. Ibbotson calculates total returns in the same method as the funds.
The funds may also compare performance to that of other compilations or
indices that may be developed and made available in the future.
The fund may compare its performance or the performance of securities in
which it may invest to averages published by IBC USA (Publications), Inc.
of Ashland, Massachusetts. These averages assume reinvestment of
distributions. The IBC/Donoghue's MONEY FUND AVERAGESTM/All Taxable, which
is reported in the MONEY FUND REPORT(registered trademark), covers over
   753     taxable money market funds.
In advertising materials, Fidelity may reference or discuss its products
and services, which may include other Fidelity funds; retirement investing;
brokerage products and services; model portfolios or allocations; saving
for college or other goals; charitable giving; and the Fidelity credit
card. In addition, Fidelity may quote or reprint financial or business
publications and periodicals as they relate to current economic and
political conditions, fund management, portfolio composition, investment
philosophy, investment techniques, the desirability of owning a particular
mutual fund, and Fidelity services and products. Fidelity may also reprint,
and use as advertising and sales literature, articles from Fidelity Focus,
a quarterly magazine provided free of charge to Fidelity fund shareholders.
The fund may present its fund number, QuotronTM number, and CUSIP number,
and discuss or quote its current portfolio manager.
The fund may be available for purchase through retirement plans or other
programs offering deferral of, or exemption from, income taxes, which may
produce superior after-tax returns over time. For example, a $1,000
investment earning a taxable return of 10% annually would have an after-tax
value of $1,949 after ten years, assuming tax was deducted from the return
each year at a 31% rate. An equivalent tax-deferred investment would have
an after-tax value of $2,100 after ten years, assuming tax was deducted at
a 31% rate from the tax-deferred earnings at the end of the ten-year
period.
As of August 31, 1995, FMR advised over $   26.5     billion in tax-free
fund assets, $   79     billion in money market fund assets, $   218    
billion in equity fund assets, $   56     billion in international fund
assets, and $   23     billion in Spartan fund assets. The fund may
reference the growth and variety of money market mutual funds and the
adviser's innovation and participation in the industry. The equity funds
under management figure represents the largest amount of equity fund assets
under management by a mutual fund investment adviser in the United States,
making FMR America's leading equity (stock) fund manager. FMR, its
subsidiaries, and affiliates maintain a worldwide information and
communications network for the purpose of researching and managing
investments abroad.
In addition to performance rankings, the fund may compare its total expense
ratio to the average total expense ratio of similar funds tracked by
Lipper. A fund's total expense ratio is a significant factor in comparing
bond and money market investments because of its effect on yield.
ADDITIONAL PURCHASE, EXCHANGE AND REDEMPTION INFORMATION
If the Trustees determine that existing conditions make cash payments
undesirable, redemption payments may be made in whole or in part in
securities or other property, valued for this purpose as they are valued in
computing the fund's NAV. Shareholders receiving securities or other
property on redemption may realize a gain or loss for tax purposes, and
will incur any costs of sale, as well as the associated inconveniences.
Pursuant to Rule 11a-3 under the 1940 Act, the fund is required to give
shareholders at least 60 days' notice prior to terminating or modifying its
exchange privilege. Under the Rule, the 60-day notification requirement may
be waived if (i) the only effect of a modification would be to reduce or
eliminate an administrative fee, redemption fee or deferred sales charge
ordinarily payable at the time of an exchange, or (ii) the fund suspends
the redemption of the shares to be exchanged as permitted under the 1940
Act or the rules and regulations thereunder, or the fund to be acquired
suspends the sale of its shares because it is unable to invest amounts
effectively in accordance with its investment objective and policies.
In the prospectus, the fund has notified shareholders that it reserves the
right at any time, without prior notice, to refuse exchange purchases by
any person or group if, in FMR's judgment, the fund would be unable to
invest effectively in accordance with its investment objective and
policies, or would otherwise potentially be adversely affected.
DISTRIBUTION   S     AND TAXES
DISTRIBUTIONS. If you request to have distributions mailed to you and the
U.S. Postal Service cannot deliver your checks, or if your checks remain
uncashed for six months, Fidelity may reinvest your distributions at the
then-current NAV. All subsequent distributions will then be reinvested
until you provide Fidelity with alternate instructions.
DIVIDENDS. Because the fund's income is primarily derived from interest,
dividends from the fund generally will not qualify for the
dividends-received deduction available to corporate shareholders.
Short-term capital gains are distributed as dividend income, but do not
qualify for the dividends received deduction. A portion of the fund's
dividends derived from certain U.S. Government obligations may be exempt
from state and local taxation. The fund will send each shareholder a notice
in January describing the tax status of dividend and capital gain
distributions (if any) for the prior year.
CAPITAL GAIN DISTRIBUTIONS. The fund may distribute any net realized
short-term capital gains once a year or more often as necessary, to
maintain its net asset value at $1.00 per share. The fund does not
anticipate earning long-term capital gains on securities held by the fund. 
   As of August 31, 1995, the fund had a capital loss carryforward
aggregating approximately $278,000. This loss carryforward, of which
$278,000 will expire on August 31, 2002, is available to offset future
capital gains.    
FOREIGN TAXES. Foreign governments may withhold taxes on dividends and
interest paid with respect to foreign securities. Foreign governments may
also impose taxes on other payments or gains with respect to foreign
securities. If, at the close of its fiscal year, more than 50% of the
fund's total assets are invested in securities of foreign issuers, the fund
may elect to pass through foreign taxes paid and thereby allow shareholders
to take a credit or deduction on their individual tax returns.
TAX STATUS OF THE FUND. The fund intends to qualify each year as a
"regulated investment company" for tax purposes so that it will not be
liable for federal tax on income and capital gains distributed to
shareholders. In order to qualify as a regulated investment company and
avoid being subject to federal income or excise taxes at the fund level,
the fund intends to distribute substantially all of its net investment
income and net realized capital gains within each calendar year as well as
on a fiscal year basis. 
The fund is treated as a separate entity from the other funds of Fidelity
Money Market Trust for tax purposes.
OTHER TAX INFORMATION. The information above is only a summary of some of
the tax consequences generally affecting the fund and its shareholders, and
no attempt has been made to discuss individual tax consequences. In
addition to federal income taxes, shareholders may be subject to state and
local taxes on fund distributions, and shares may be subject to state and
local personal property taxes. Investors should consult their tax advisers
to determine whether the fund is suitable to their particular tax
situation.
FMR
All of the stock of FMR is owned by FMR Corp., its parent organized in
1972. The voting common stock of FMR Corp. is divided into two classes.
Class B is held predominantly by members of the Edward C. Johnson 3d family
and is entitled to 49% of the vote on any matter acted upon by the voting
common stock. Class A is held predominantly by non-Johnson family member
employees of FMR Corp. and its affiliates and is entitled to 51% of the
vote on any such matter. The Johnson family group and all other Class B
shareholders have entered into a shareholders' voting agreement under which
all Class B shares will be voted in accordance with the majority vote of
Class B shares. Under the 1940 Act, control of a company is presumed where
one individual or group of individuals owns more than 25% of the voting
stock of that company. Therefore, through their ownership of voting common
stock and the execution of the shareholders' voting agreement, members of
the Johnson family may be deemed, under the 1940 Act, to form a controlling
group with respect to FMR Corp.
At present, the principal operating activities of FMR Corp. are those
conducted by three of its divisions as follows: FSC, which is the transfer
and shareholder servicing agent for certain funds advised by FMR; FIIOC,
which performs shareholder servicing functions for institutional customers
and funds sold through intermediaries; and Fidelity Investments Retail
Marketing Company, which provides marketing services to various companies
within the Fidelity organization.
Fidelity investment personnel may invest in securities for their own
account pursuant to a code of ethics that sets forth all employees'
fiduciary responsibilities regarding the funds, establishes procedures for
personal investing and restricts certain transactions. For example, all
personal trades in most securities require pre-clearance, and participation
in initial public offerings is prohibited. In addition, restrictions on the
timing of personal investing in relation to trades by Fidelity funds and on
short-term trading have been adopted.

* Information is as of December 31, 1994 for 206 funds in the complex.
** Interested trustees of the fund are compensated by FMR.
Under a retirement program adopted in July 1988, the non-interested
Trustees, upon reaching age 72, become eligible to participate in a
retirement program under which they receive payments during their lifetime
from a fund based on their basic trustee fees and length of service. The
obligation of a fund to make such payments is not secured or funded.
Trustees become eligible if, at the time of retirement, they have served on
the Board for at least five years. Currently, Messrs. Ralph S. Saul,
William R. Spaulding, Bertram H. Witham, and David L. Yunich, all former
non-interested Trustees, receive retirement benefits under the program.
On    August 31, 1995    , the Trustees and officers of the fund owned, in
the aggregate, less than 1% of the fund's total outstanding shares.
As of    September 30, 1995    ,    there were no owners of     record or
beneficially    of     5% or more of outstanding shares of the fund   .    
MANAGEMENT CONTRACT
The fund employs FMR to furnish investment advisory and other services.
Under its management contract with the fund, FMR acts as investment adviser
and, subject to the supervision of the Board of Trustees, directs the
investments of the fund in accordance with its investment objective,
policies and limitations. FMR also provides the fund with all necessary
office facilities and personnel for servicing the fund's investments,
compensates all officers of the fund and all Trustees who are "interested
persons" of the fund or of FMR, and all personnel of the fund or FMR
performing services relating to research, statistical and investment
activities.
In addition, FMR or its affiliates, subject to the supervision of the Board
of Trustees, provide the management and administrative services necessary
for the operation of the fund. These services include providing facilities
for maintaining the fund's organization; supervising relations with
custodians, transfer and pricing agents, accountants, underwriters, and
other persons dealing with the fund; preparing all general shareholder
communications and conducting shareholder relations; maintaining the fund's
records and the registration of the fund's shares under federal and state
laws; developing management and shareholder services for the fund; and
furnishing reports, evaluations and analyses on a variety of subjects to
the Trustees.
FMR is responsible for the payment of all expenses of the fund with certain
exceptions. Specific expenses payable by FMR include, without limitation,
expenses for the typesetting, printing, and mailing proxy materials to
shareholders; legal expenses, and the fees of the custodian and auditor;
costs of typesetting, printing, and mailing prospectuses and statements of
additional information, notices and reports to shareholders; the fund's
proportionate share of insurance premiums and Investment Company Institute
dues. FMR also provides for transfer agent and dividend disbursing services
through FIIOC and the fund and general accounting record maintenance
through FSC. 
FMR pays all other expenses of the fund with the following exceptions: fees
and expenses of all Trustees of the Trust who are not "interested persons"
of the Trust or FMR (the non-interested Trustees); taxes; brokerage
commissions (if any); and such nonrecurring expenses as may arise,
including costs of any litigation to which a fund may be a party, and any
obligation it may have to indemnify the officers and Trustees with respect
to litigation.
FMR is the fund's manager pursuant to a management contract dated December
29, 1994 which was approved by shareholders on December 8, 1994. The
management fee paid to FMR is reduced by an amount equal to the fees and
expenses    paid by the fund to     the non-interested Trustees.
For the services of FMR under the contract, the fund pays FMR a monthly
management fee at the annual rate of 0.42% of the average net assets of the
fund throughout the month. For the fiscal years ended August 31, 1995,
1994   ,     and 1993, FMR received $   15,255,240, $9,368,441, and
$6,964,571    , respectively, after reduction of fees and expenses    paid
by the fund to     the non-interested Trustees.
FMR may, from time to time, voluntarily reimburse all or a portion of the
fund's operating expenses (exclusive of interest, taxes, brokerage
commissions, and extraordinary expenses). FMR retains the ability to be
repaid for these expense reimbursements in the amount that expenses fall
below the limit prior to the end of the fiscal year. Expense reimbursements
by FMR will increase the fund's total returns and yield and repayment of
the reimbursement by the fund will lower its total returns and yield.
To comply with the California Code of Regulations, FMR will reimburse the
fund if and to the extent that the fund's aggregate annual operating
expenses exceed specified percentages of its average net assets. The
applicable percentages are 2 1/2% of the first $30 million, 2% of the next
$70 million, and 1 1/2% of average net assets in excess of $100 million.
When calculating the fund's expenses for purposes of this regulation, the
fund may exclude interest, taxes, brokerage commissions, and extraordinary
expenses, as well as a portion of its custodian fees attributable to
investments in foreign securities.
SUB-ADVISER. FMR has entered into a sub-advisory agreement with FMR Texas
pursuant to which FMR Texas has primary responsibility for providing
portfolio investment management services to the fund.
Under the sub-advisory agreement, dated December 29, 1994, which was
approved by shareholders on December 8, 1994, FMR pays FMR Texas fees equal
to 50% of the management fee payable to FMR under its management contract
with the fund. The fees paid to FMR Texas are not reduced by any voluntary
or mandatory expense reimbursements that may be in effect from time to
time. On behalf of the fund, for fiscal 1995, 1994, and 1993, FMR paid FMR
Texas fees of $   7,627,620, $4,684,221, and $3,482,286    , respectively.
   CONTRACTS WITH FMR AFFILIATES
FIIOC is transfer, dividend disbursing, and shareholders' servicing agent
for the fund. The costs of these services are borne by FMR pursuant to its
management contract with the fund. FSC calculates the fund's NAV and
dividends and maintains the fund's general accounting records. The cost of
these services are also borne by FMR pursuant to its management contract
with the fund. 
The fund has a distribution agreement with FDC, a Massachusetts corporation
organized on July 18, 1960. FDC is a broker-dealer registered under the
Securities Exchange Act of 1934 and is a member of the National Association
of Securities Dealers, Inc. The distribution agreement calls for FDC to use
all reasonable efforts, consistent with its other business, to secure
purchasers for shares of the fund, which are continuously offered at net
asset value. Promotional and administrative expenses in connection with the
offer and sale of shares are paid by FMR.    
DISTRIBUTION AND SERVICE PLAN
The Trustees have approved a Distribution and Service Plan on behalf of the
fund (the Plan) pursuant to Rule 12b-1 under the 1940 Act (the Rule). The
Rule provides in substance that a mutual fund may not engage directly or
indirectly in financing any activity that is primarily intended to result
in the sale of shares of a fund except pursuant to a plan on behalf of the
fund under the Rule. The Plan, as approved by the Trustees, allows the fund
and FMR to incur certain expenses that might be considered to constitute
indirect payment by the fund of distribution expenses.
Under the Plan, if the payment of management fees by the fund to FMR is
deemed to be indirect financing by the fund of the distribution of its
shares, such payment is authorized by the Plan. The Plan specifically
recognizes that FMR        may use its management fee revenue,    as well
as its     past profits or    its     other resources    from any other
source     to    reimburse FDC for expenses incurred in connection with the
distribution of fund shares, including     payments    made     to third
parties that assist in selling shares of the fund, or to third parties,
including banks, that render shareholder support services. The Trustees
have not authorized such payments to date.
Prior to approving the Plan, the Trustees carefully considered all
pertinent factors relating to the implementation of the Plan, and have
determined that there is a reasonable likelihood that the Plan will benefit
the fund and its shareholders. In particular, the Trustees noted that the
Plan does not authorize payments by the fund other than those made to FMR
under its management contract with the fund. To the extent that the Plan
gives FMR and FDC greater flexibility in connection with the distribution
of shares of the fund, additional sales of fund shares may result.
Furthermore, certain shareholder support services may be provided more
effectively under the Plan by local entities with whom shareholders have
other relationships.
The Plan was approved by shareholders of the fund on December 8, 1994. The
Plan was approved by shareholders in connection with a reorganization
transaction on December 29, 1994, pursuant to an Agreement and Plan of
Conversion.
The Glass-Steagall Act generally prohibits federally and state chartered or
supervised banks from engaging in the business of underwriting, selling, or
distributing securities. Although the scope of this prohibition under the
Glass-Steagall Act has not been clearly defined by the courts or
appropriate regulatory agencies, FDC believes that the Glass-Steagall Act
should not preclude a bank from performing shareholder support services, or
servicing and recordkeeping functions. FDC intends to engage banks only to
perform such functions. However, changes in federal or state statutes and
regulations pertaining to the permissible activities of banks and their
affiliates or subsidiaries, as well as further judicial or administrative
decisions or interpretations, could prevent a bank from continuing to
perform all or a part of the contemplated services. If a bank were
prohibited from so acting, the Trustees would consider what actions, if
any, would be necessary to continue to provide efficient and effective
shareholder services. In such event, changes in the operation of the fund
might occur, including possible termination of any automatic investment or
redemption or other services then provided by the bank. It is not expected
that shareholders would suffer any adverse financial consequences as a
result of any of these occurrences. In addition, state securities laws on
this issue may differ from the interpretations of federal law expressed
herein, and banks and other financial institutions may be required to
register as dealers pursuant to state law.
The fund may execute portfolio transactions with, and purchase securities
issued by, depository institutions that receive payments under the Plan. No
preference for the instruments of such depository institutions will be
shown in the selection of investments.
DESCRIPTION OF THE TRUST
TRUST ORGANIZATION. Retirement Money Market Portfolio is a fund of Fidelity
Money Market Trust, an open-end management investment company originally
organized as a Massachusetts business trust on August 21, 1978 pursuant to
a Declaration of Trust that was amended and restated November 1, 1989. On
December 29, 1994, the trust was converted to a Delaware business trust
pursuant to an agreement approved by shareholders on December 8, 1994. The
Delaware trust, which was organized on June 20, 1991 under the name of
Fidelity Money Market Trust II, succeeded to the name Fidelity Money Market
Trust on December 29, 1994. Currently, there are    three     funds of the
trust:    Rated     Money Market; Retirement Money Market Portfolio; and
Retirement Government Money Market Portfolio. The Trust Instrument permits
the Trustees to create additional funds.
In the event that FMR ceases to be the investment adviser to the fund, the
right of the trust or fund to use the identifying name "Fidelity" may be
withdrawn.
The assets of the trust, received for the issue or sale of shares of each
fund and all income, earnings, profits, and proceeds thereof, subject only
to the rights of creditors, are especially allocated to such fund, and
constitute the underlying assets of such fund. The underlying assets of
each fund are segregated on the books of account, and are to be charged
with the liabilities with respect to such fund and with a share of the
general expenses of the trust. Expenses with respect to the trust are to be
allocated in proportion to the asset value of the respective funds, except
where allocations of direct expense can otherwise be fairly made. The
officers of the trust, subject to the general supervision of the Board of
Trustees, have the power to determine which expenses are allocable to a
given fund, or which are general or allocable to all of the funds. In the
event of the dissolution or liquidation of the trust, shareholders of each
fund are entitled to receive as a class the underlying assets of such fund
available for distribution.
SHAREHOLDER AND TRUSTEE LIABILITY. The trust is a business trust organized
under Delaware law. Delaware law provides that shareholders shall be
entitled to the same limitations of personal liability extended to
stockholders of private corporations for profit. The courts of some states,
however, may decline to apply Delaware law on this point. The Trust
Instrument contains an express disclaimer of shareholder liability for the
debts, liabilities, obligations, and expenses of the trust and requires
that a disclaimer be given in each contract entered into or executed by the
trust or the Trustees. The Trust Instrument provides for indemnification
out of each fund's property of any shareholder or former shareholder held
personally liable for the obligations of the fund. The Trust Instrument
also provides that each fund shall, upon request, assume the defense of any
claim made against any shareholder for any act or obligation of the fund
and satisfy any judgment thereon. Thus, the risk of a shareholder incurring
financial loss on account of shareholder liability is limited to
circumstances in which Delaware law does not apply, no contractual
limitation of liability was in effect, and the fund is unable to meet its
obligations. FMR believes that, in view of the above, the risk of personal
liability to shareholders is extremely remote.
The Trust Instrument further provides that the Trustees, if they have
exercised reasonable care, shall not be personally liable to any person
other than the trust or its shareholders; moreover, the Trustees shall not
be liable for any conduct whatsoever, provided that Trustees are not
protected against any liability to which they would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence, or reckless
disregard of the duties involved in the conduct of their office. 
VOTING RIGHTS. Each fund's capital consists of shares of beneficial
interest. As a shareholder, you receive one vote for each dollar value of
NAV you own. The shares have no preemptive or conversion rights; the voting
and dividend rights, the right of redemption, and the privilege of exchange
are described in the Prospectus. Shares are fully paid and nonassessable,
except as set forth under the heading "Shareholder and Trustee Liability"
above. Shareholders representing 10% or more of the trust or a fund may, as
set forth in the Trust Instrument, call meetings of the trust or fund for
any purpose related to the trust or fund, as the case may be, including, in
the case of a meeting of the entire trust, the purpose of voting on removal
of one or more Trustees. 
The trust or any fund may be terminated upon the sale of its assets to, or
merger with, another open-end management investment company or series
thereof, or upon liquidation and distribution of its assets. Generally such
terminations must be approved by vote of the holders of a majority of the
trust or the fund, as determined by the current value of each shareholder's
investment in the fund or trust; however, the Trustees may, without prior
shareholder approval, change the form of organization of the trust by
merger, consolidation, or incorporation. If not so terminated or
reorganized, the trust and its funds will continue indefinitely.
Under the Trust Instrument, the Trustees may, without shareholder vote,
cause the trust to merge or consolidate into one or more trusts,
partnerships, or corporations, or cause the trust to be incorporated under
Delaware law, so long as the surviving entity is an open-end management
investment company that will succeed to or assume the trust registration
statement. Each fund may invest all of its assets in another investment
company.
CUSTODIAN. Morgan Guaranty Trust Company of New York, 60 Wall Street, New
York, NY, is custodian of the assets of the fund. The custodian is
responsible for the safekeeping of a fund's assets and the appointment of
the subcustodian banks and clearing agencies. The custodian takes no part
in determining the investment policies of a fund or in deciding which
securities are purchased or sold by a fund. However, a fund may invest in
obligations of the custodian and may purchase securities from or sell
securities to the custodian. The Bank of New York and Chemical Bank, each
headquartered in New York, also may serve as a special purpose custodian of
certain assets in connection with pooled repurchase agreement transactions.
FMR, its officers and directors, its affiliated companies, and the Board of
Trustees may, from time to time, conduct transactions with various banks,
including banks serving as custodians for certain funds advised by FMR.
Transactions that have occurred to date include mortgages and personal and
general business loans. In the judgment of FMR, the terms and conditions of
those transactions were not influenced by existing or potential custodial
or other fund relationships.
AUDITOR.    Coopers & Lybrand L.L.P.     1999 Bryan Street, Dallas, Texas,
serves as the fund's independent accountant. The auditor examines financial
statements for the fund and provides other audit, tax, and related
services.

APPENDIX
The descriptions that follow are examples of eligible ratings for the fund.
The fund, may, however, consider the ratings for other types of investments
and the ratings assigned by other rating organizations when determining the
eligibility of a particular investment.
DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S COMMERCIAL PAPER RATINGS:
Issuers rated PRIME-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. Prime-1
repayment capacity will normally be evidenced by the following
characteristics:
(medium solid bullet) All of your purchases must be made in U.S. dollars
and checks must be drawn on U.S. banks. 
(medium solid bullet) Leading market positions in well established
industries.
(medium solid bullet) High rates of return on funds employed.
(medium solid bullet) Conservative capitalization structures with moderate
reliance on debt and ample asset protection.
(medium solid bullet) Broad margins in earnings coverage of fixed financial
charges and with high internal cash generation.
(medium solid bullet) Well established access to a range of financial
markets and assured sources of alternate liquidity.
Issuers rated PRIME-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will
normally be evidenced by many of the characteristics cited above but to a
lesser degree. Earnings trends and coverage ratios, while sound, will be
more subject to variation. Capitalization characteristics, while still
appropriate, may be more affected by external conditions. Ample alternate
liquidity is maintained.
DESCRIPTION OF STANDARD & POOR'S CORPORATION'S COMMERCIAL PAPER RATINGS:
A - Issuers assigned this highest rating are regarded as having the
greatest capacity for timely payment. Issues in this category are
delineated with the numbers 1, 2, and 3 to indicate the relative degree of
safety.

payment is either overwhelming or very strong. Those issues determined to
possess overwhelming safety characteristics will be denoted with a plus (+)
sign designation.
A-2 - Capacity for timely payment on issues with this designation is
strong. However, the relative degree of safety is not as high as for issues

it is not under common control with these other funds since the power

official position with the respective funds.

extent permitted by law against liability and all expenses reasonably
incurred by him or her in connection with any claim, action, suit or

as a trustee, an officer, or both.  Additionally, amounts paid or incurred
