     SUMMARY OF PORTFOLIO EXPENSES

              The purpose of the table below is to assist investors in
     understanding the various costs and expenses that an investor in the
     Portfolios would bear directly or indirectly. This standard format was
     developed for use by all mutual funds to help investors make their
     investment decisions. This expense information should be considered along
     with other important information such as each Portfolio's investment
     objective and its past performance. There are no transaction expenses
     associated with purchases or sales of the Portfolios' shares.

     B.       EXAMPLE
        
              You would pay the following expenses on a $1,000 investment  in
     each Portfolio, assuming (1) 5% annual return and (2) redemption at the
     end of each time period:

     EXPLANATION OF TABLE
        
     A.       ANNUAL PORTFOLIO OPERATING EXPENSES are based on the Portfolios'
     historical expenses. Management fees are paid by each Portfolio to
     Fidelity Management & Research Company (FMR) for managing its investments
     and business affairs. FMR is responsible for all other expenses of the
     Portfolios with certain exceptions. Management Fees and Other Expenses are
     reflected in each Portfolio's share price or dividends and are not charged
     directly to the individual shareholder accounts. Please refer to the
     section entitled "Management Contracts, Distribution and Service Plans" on
     page ^ 13 for further information.

     INVESTMENT OBJECTIVES AND POLICIES
        
              The investment objective of each Portfolio is to obtain as high a
     level of current income as is consistent with the preservation of
     principal and liquidity within the standards prescribed for each
     Portfolio. Each Portfolio's investment objective is fundamental and may
     not be changed without the affirmative vote of a majority of the
     outstanding shares of the Portfolio. No assurance can be made that a
     Portfolio will achieve its objective.  ^ Each Portfolio is different in
     terms of ^ its permitted investments and investment techniques.  Each
     Portfolio seeks to maintain a $1.00 share price at all times. The
     permitted investments of the Portfolios are as follows:
         
        
              U.S. TREASURY PORTFOLIO invests in instruments which are issued
     or guaranteed as to principal and interest by the U.S. government and thus
     constitute direct obligations of the United States ^, and in repurchase
     agreements backed by these instruments.  These instruments include U.S.
     Treasury bills, notes, and bonds, and instruments issued by the
     Export-Import Bank of the ^ United States, the General Services
     Administration, the Government National Mortgage Association, the Small
     Business Administration and the Washington Metropolitan Area Transit
     Authority. As a ^ non-fundamental operating policy, the Portfolio intends
     to invest 100% of its total assets in U.S. Treasury bills, notes and bonds
     and other direct obligations of the U.S. Treasury.  The Portfolio may also
     engage in repurchase agreements backed by these obligations. This policy
     may be changed only upon 90 days' notice to shareholders.
         
        
              U.S. GOVERNMENT PORTFOLIO invests in instruments issued or
     guaranteed as to principal and interest by the U.S. government or by any
     of its agencies or instrumentalities (U.S. government obligations) or in
     repurchase agreements backed by such instruments.  ^ U.S. Government
     Portfolio and ^ U.S. Treasury Portfolio are distinguishable from one
     another in that ^ U.S. Government Portfolio may include instruments which
     are backed only by the right of the issuer to borrow from the U.S.
     Treasury or are backed only by the credit of the agency or instrumentality
     issuing the obligations. Such instruments are not deemed direct
     obligations of the United States ^ and thus will not be ^  purchased by
     U.S. Treasury Portfolio.
         
              DOMESTIC MONEY MARKET PORTFOLIO invests in high quality U.S.
     dollar-denominated money market instruments of domestic issuers such as
     (i) bank obligations including certificates of deposit (CDs) and bankers'
     acceptances of U.S. banks; (ii) commercial paper; (iii) other debt
     obligations; and (iv) U.S. government obligations. Other debt obligations
     include, but are not limited to, municipal obligations, asset-backed
     securities, restricted securities, and securities issued by special
     purpose entities.
        
              Each Portfolio may engage in repurchase agreements and reverse
     repurchase agreements with those parties whose creditworthiness has been

     illiquid securities.
         
        
              The Trust has adopted a non-fundamental policy ^ on behalf of
     each Portfolio which requires each Portfolio to use its best efforts to
     maintain a constant net asset value per share (NAV) of $1.00 ^, and to
     value its portfolio securities on the basis of the amortized cost
     valuation method, pursuant to Rule 2a-7 under the Investment Company Act
     of 1940 (the 1940 Act). This method is based on acquisition cost and
     assumes a steady rate of amortization of premium or discount from the date
     of purchase until maturity instead of looking at actual changes in market
     values.
         
              REGULATORY REQUIREMENTS. The following is a brief summary of
     regulatory requirements applicable to all money market funds, which limit
     certain of the Portfolios' investment policies, though U.S Treasury
     Portfolio and U.S. Government Portfolio follow more restrictive policies,
     as described above.

     .        QUALITY. Pursuant to procedures adopted by the Board of Trustees,
     each Portfolio may purchase only high quality securities that FMR believes
     present minimal credit risks. To be considered high quality, a security
     must be a U.S. government security; or rated in accordance with applicable
     rules in one of the two highest rating categories for short-term
     securities by at least two nationally recognized statistical rating
     organizations (NRSROs) (or one, if only one rating agency 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 have received the highest
     rating (e.g., Standard & Poor's A-1 rating) from at least two rating
     services (or one, if only one has rated the security). SECOND TIER
     SECURITIES have received ratings within the two highest categories (e.g.,
     Standard & Poor's A-1 or A-2 rating) from at least two rating agencies (or
     one, if only one has rated the security), but do not qualify as first tier
     securities. If a security has been assigned different ratings by different
     rating agencies, at least two rating agencies must have assigned the
     higher rating in order for FMR to determine eligibility on the basis of
     that higher rating. Based on procedures adopted by the Board of Trustees,
     FMR may determine that an unrated security is of equivalent quality to a
     rated first or second tier security.

        
     .        DIVERSIFICATION. Domestic Money Market Portfolio may not invest
     more than 5% of its total assets in second tier securities. In addition, ^
     Domestic Money Market Portfolio 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.

     .        MATURITY. The Portfolios must limit their investments to
     securities with remaining maturities of 397 days or less and must maintain
     a dollar-weighted average maturity of 90 days or less.
        
     Each Portfolio's ability to achieve its investment objective depends on
     the quality and maturity of its investments. Although the Portfolios'
     policies are designed to help maintain a stable $1.00 share price, all
     money market instruments can change in value when interest rates or
     issuers' creditworthiness change, or if an issuer or guarantor of a
     security fails to pay interest or principal when due. If these changes in
     value were large enough, a Portfolio's share price could fall below $1.00.
     In general, securities with longer maturities are more ^ sensitive to
     interest rate changes than are short-term securities, although those with
     longer maturities may provide higher yields.
         
        
              INVESTMENT LIMITATIONS. The following summarizes each Portfolio's
     principal investment limitations. A complete listing is contained in the ^
     SAI.
         
        
                      ^(1)     (a) With respect to 75% of its total assets, each
     Portfolio normally may not invest more than 5% of its total assets in the
     securities of any one issuer (other than U.S. government securities) ^.  
     (b) Under certain conditions, however, ^ each Portfolio may invest up to
     10% of its total assets in the first tier securities of a single issuer
     for up to three days^; 
         
        
                      ^(2)     Each Portfolio will not purchase a security
     (other than U.S. government securities) if, as a result, more than 25% of
     its total assets would be invested in ^ the securities of issuers whose
     prinicipal business activities are in the same industry, provided that ^
     Domestic Money Market Portfolio ^ will invest more than 25% of its total
     assets ^ in the financial services industry^.
         
        
                      ^(3)     Each Portfolio may (a) borrow money for temporary
     or emergency purposes ^ and (b) engage in reverse repurchase agreements ^
     for any purpose; provided that (a) and (b) in combination do not exceed 33
     1/3% of its total assets; ^(c) borrow money only from a bank or from other
     funds advised by FMR or an affiliate; and ^(d) may not purchase any
     security while borrowings (other than reverse repurchase agreements)
     representing more than 5% of its total assets are outstanding; and 
         
        
                      ^(4)     Domestic Money Market Portfolio (a) may lend its
     portfolio securities to broker-dealers and institutions but only when the
     loans are fully collateralized; (b) may make loans to other funds advised
     by FMR and its affiliates not to exceed 10% of its net assets; and (c)
     will limit these loans to 33 1/3% of its total assets.
         

                                        - 8 -                         Prospectus
<PAGE>






        
              Limitations 1(a), 2, 3(a), 3(b), and 4(c) are fundamental
     limitations. Each Portfolio's investment policies and limitations, unless
     otherwise indicated, are not fundamental, and may be changed without
     shareholder approval. Except for the percentage limitation in 4(c), these
     limitations and policies are considered at the time of purchase; the sale
     of securities is not required in the event of a subsequent change in
     circumstances.
         
        
     Because Domestic Money Market Portfolio concentrates more than 25% of its
     total assets in the financial services industry, its performance may be
     affected by conditions affecting banks and other financial services
     companies. Companies in the financial services industry are subject to
     various risks related to that industry, such as governmental regulation,
     changes in interest rates, and exposure on loans, including loans to
     foreign borrowers.  ^ Investments in the financial services industry may
     include obligations of domestic banks, savings and loan associations,
     consumer and industrial finance companies, securities brokerage companies,
     leasing companies, and a variety of firms in the insurance field. These
     obligations include time deposits, certificates of deposit, bankers'
     acceptances, and commercial paper.
         
              SUITABILITY. The Trust is designed as an economical and
     convenient vehicle for those institutional, corporate and individual
     investors seeking to obtain the yields available from money market
     instruments while maintaining liquidity. 

              The Trust is designed particularly for banks seeking investment
     of short-term monies held in accounts for which the bank acts in a
     fiduciary, advisory, agency, custodial or similar capacity. The Trust may
     be equally suitable for the investment of short-term funds held or managed
     by corporations, employee benefit plans, insurance companies, unions,
     hospitals, investment counselors, professional firms, educational,
     religious and charitable organizations, investment bankers, brokers, and
     others, if consistent with the objectives of the particular account and
     any applicable state and federal laws and regulations. 

              The Trust offers the advantages of large purchasing power and
     diversification, thereby avoiding the generally greater expense of
     executing a large number of small transactions. The Trust also makes it
     possible for individual investors to participate in a more diversified
     portfolio of money market instruments than the size of their investments
     might otherwise permit. Moreover, investment in the Trust relieves the
     investor of many management and administrative burdens usually associated
     with the direct purchase and sale of money market instruments. These
     include selection of portfolio investments; surveying the market for the
     best terms at which to buy and sell; scheduling and monitoring maturities
     and reinvestments; receipt, delivery and safekeeping of securities; and
     portfolio recordkeeping.

              PORTFOLIO TRANSACTIONS. Money market obligations generally are
     traded in the over-the-counter market through broker-dealers. A
     broker-dealer is a securities firm or bank which makes a market for
     securities by offering to buy at one price and sell at a slightly higher
     price. The difference between the prices is known as a spread. Since FMR
     trades, directly or through affiliated sub- advisers, a large number of
     securities, including those of Fidelity's other funds, broker-dealers are
     willing to work with the funds on a more favorable spread than would be
     possible for most individual investors. 
        
              Each Portfolio has authorized FMR to allocate transactions to
     some broker-dealers who help distribute the Portfolio's shares or the
     shares of Fidelity's other funds to the extent permitted by law, and on an
     agency basis to an affiliate, Fidelity Brokerage Services, Inc. (FBSI).
     FMR will allocate such transactions if commissions are comparable to those
     charged by non-affiliated qualified broker-dealers for similar services.
     Higher commissions may be paid to those firms that provide research
     services to the extent permitted by law. FMR also is authorized to
     allocate brokerage transactions to FBSI in order to secure from FBSI
     research services produced by third party, independent entities. FMR may
     use this research information in managing the ^ Portfolios' assets, as
     well as assets of other clients.
         
     PERFORMANCE
        
              From time to time each Portfolio ^ advertises its YIELD and 
     EFFECTIVE YIELD in advertisements or in reports or other communications
     with shareholders. Both yield figures are based on historical earnings and
     are not intended to indicate future performance. Each Portfolio's yield
     and effective yield figures are illustrated below for the seven-day period
     ended August 31,  ^ 1994:
         
        
       U.S. Treasury           U.S. Government           Domestic Money 
        Portfolio                Portfolio              Market Portfolio
        ------------           ---------------          ----------------
                 Effective             Effective               Effective
     Yield        Yield      Yield     Yield        Yield      Yield
     ^___%           ___%          ___%       ___%      ____%    x.xx%
         
              Each Portfolio's YIELD refers to the income generated by an
     investment in the Portfolio over a seven-day period expressed as an annual
     percentage rate. The EFFECTIVE YIELD is calculated similarly, but assumes
     that the income earned from the investment is reinvested. The effective
     yield will be slightly higher than the yield because of the compounding
     effect on this assumed reinvestment. 

              Each Portfolio's TOTAL RETURN is based on the overall dollar or
     percentage change in value of a hypothetical investment in a Portfolio,
     assuming dividends are reinvested. A CUMULATIVE TOTAL RETURN reflects a
     Portfolio's performance over a stated period of time. An AVERAGE ANNUAL
     TOTAL RETURN reflects the hypothetical annually compounded rate that would

                                        - 10 -                        Prospectus
<PAGE>






     have produced the same cumulative total return if performance had been
     constant over the entire period. Because average annual returns tend to
     smooth out variations in a Portfolio's performance, investors should
     recognize that they are not the same as actual year-by-year results.
        
              Each ^ Portfolio may be rated to reflect investment quality by a
     ^ NRSRO.  These quality ratings are based on, but not limited to, an
     analysis of a Portfolio's operational policies, investment strategies and
     management.  These ^ NRSROs also may undertake an ongoing analysis and
     assessment of these criteria in order to continually update a Portfolio's
     rating.
         
     DISTRIBUTIONS AND TAXES

              Each Portfolio ordinarily declares dividends from net investment
     income daily and pays such dividends monthly. Each Portfolio intends to
     distribute substantially all of its net investment income and capital
     gains, if any, to shareholders within each calendar year as well as on a
     fiscal year basis.
        

              FEDERAL TAXES. Dividends derived from net investment income and
     short-term capital gains are taxable as ordinary income. Each Portfolio's
     distributions are taxable when they are paid, whether they are taken in
     cash or reinvested in additional shares, except that distributions
     declared in December and paid in January are taxable as if paid on
     December 31.  The Portfolios will send shareholders an ^ Internal Revenue
     Service (IRS) Form 1099-DIV by January ^ 31 showing taxable distributions
     for the past calendar year.
         
        
              OTHER TAX INFORMATION. The information above is only a summary of
     some of the federal tax consequences generally affecting a Portfolio and
     its shareholders, and no attempt has been made to discuss individual tax
     consequences. In addition to federal tax, investors may be subject to
     state or local taxes on their investment. Investors should consult their
     tax advisors for details and up-to-date information on the tax laws in
     their states.
         
              When investors sign the account application, they will be asked
     to certify that the social security or taxpayer identification number is
     correct and that they are not subject to 31% backup withholding for
     failing to report income to the IRS. If investors do not comply with IRS
     regulations, the IRS can require each Portfolio to withhold 31% of taxable
     distributions and redemptions.
        
              STATE AND LOCAL TAXES. Mutual fund dividends from most U.S.
     government securities generally are 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.  Ginnie mae

     securities and other mortgage-backed securities are notable exceptions in
     most states.  Some states may impose intangible property taxes.^ 
         
     HOW TO INVEST, EXCHANGE AND REDEEM

              Shares of each Portfolio are offered continuously and may be
     purchased at the NAV next determined after an order is received and
     accepted. The Portfolios do not impose any sales charges in connection
     with purchases of their shares, although institutions may charge their
     clients fees in connection with purchases and sales for the accounts of
     their clients. The Trust may discontinue offering shares generally of any
     Portfolio or in any particular state without notice to shareholders.

              IF YOU ARE INVESTING THROUGH A SECURITIES DEALER OR BANK
     (FINANCIAL INSTITUTION), CONTACT THAT FINANCIAL INSTITUTION DIRECTLY.
        
              Investors purchasing shares of the Portfolios through a program
     of services offered by a Financial Institution should read the program
     materials in conjunction with this Prospectus. Certain features of the
     Portfolios may be modified in these programs and administrative charges
     (in addition to payments the Financial Institution may receive pursuant to
     the Distribution and Service Plan) may be imposed for the services
     rendered. For further information, including copies of ^ the Prospectus,
     SAI and application, investors should contact their Financial Institution
     or the Trust directly.
         
        
              SHARE PRICE AND DIVIDENDS. Fidelity Service Co. (Service)
     calculates each Portfolio's NAV at 3:00 p.m. and 4:00 p.m. Eastern time
     each day each Portfolio is open for business (see " Holiday Schedule" on
     page ^ 12). The NAV of each Portfolio is determined by adding the value of
     all securities and other assets of the Portfolio, deducting ^ the
     Portfolio's actual and accrued liabilities, and dividing by the number of
     shares ^ of the Portfolio outstanding.  Each Portfolio values its
     portfolio securities on the basis of amortized cost.
         
              Shares purchased at the 3:00 p.m. price earn the income dividend
     declared that day. Shares purchased at the 4:00 p.m. price begin to earn
     income dividends on the following business day. Purchases made by federal
     funds wire will be processed at 3:00 p.m. price if Client Services is
     contacted before 3:00 p.m. Eastern time, and the Portfolio receives
     federal funds that day. If investors do not call Client Services to give
     notice of their wire investment before 3:00 p.m. Eastern time, their
     investment will not begin to earn dividends until the first business day
     following receipt of the wire. Investors may elect to receive monthly
     dividends in cash.

              MINIMUM INVESTMENT AND ACCOUNT BALANCE. The minimum initial
     investment to establish a new account in each Portfolio is $100,000.
     Subsequent investments may be in any amount. To keep an account open, a
     minimum balance of $100,000 must be maintained. If an account balance
     falls below $100,000 due to redemption, the Portfolio may close the

                                        - 12 -                        Prospectus
<PAGE>






     account and wire the proceeds to the bank account of record. An investor
     will be given 30 days' notice that their account will be closed unless
     they make an additional investment to increase their account balance to
     the $100,000 minimum.

              HOW TO INVEST.
        
              ^ Purchases may only be made by federal funds wire; checks will
     not be accepted for purchases. There is no fee imposed by the Portfolios
     for wire purchases. However, banks may impose such a fee.
         
              An initial investment in a Portfolio must be preceded or
     accompanied by a completed, signed application. Send the application to:

              Fidelity Investments - Client Services
              FIIOC, ZR7
              P.O. Box 1182
              Boston, MA 02103-1182

              WIRING INSTRUCTIONS. For wiring information and instructions,
     investors should call the Financial Institution through which they trade
     or Fidelity Client Services at 1-800-843- 3001.
        
     Each Portfolio requires notification of all wire purchases. To secure same
     day acceptance of federal funds, investors must telephone Client Services
     at 1-800-843-3001 between 8:30 a.m. and 3:00 p.m. Eastern time on the days
     that the Portfolios are open for business to advise them of the wire and
     to place the trade. 
     ^
         
        
              HOW TO EXCHANGE. An exchange is a convenient way to buy shares of
     the Portfolios or other Fidelity funds. Each Portfolio's shares may be
     exchanged (subject to minimum investment requirements and sales charges,
     if any) for shares of Fidelity's other funds registered in the investor's
     state. Investors must consult the prospectus of the fund to be acquired to
     determine eligibility and suitability. The redemption will be made at the
     next determined NAV of the shares to be redeemed after the exchange
     request is received. The shares of the fund to be acquired will be
     purchased at the next determined NAV after acceptance of the purchase
     order by the ^ fund (in accordance with the fund's customary policy for
     accepting investments). Each Portfolio reserves the right at any time
     without prior notice to refuse exchange purchases by any person or group
     if, in FMR's judgment, the Portfolio would be unable to invest effectively
     in accordance with its investment objective and policies or would
     otherwise potentially be adversely affected. Each Portfolio may terminate
     or modify the exchange privilege in the future.
         
        
              Exchanges may only be made between accounts that are registered
     in the same name, address, and taxpayer identification number. Exchanges
     will not be permitted until a completed and signed mutual fund application

                                        - 13 -                        Prospectus
<PAGE>






     is on file. Exchanges may be requested by calling ^ Client Services at the
     number listed above.
         
        
              HOW TO REDEEM. Investors may redeem all or a portion of their
     shares on any business day.  The ^ shares will be redeemed at the next NAV
     calculated after the Portfolio has received and accepted the redemption
     request. If an account is closed, any accrued dividends will normally be
     paid at the beginning of the following month. Redemptions may be made by
     calling Client Services at 1-800-843-3001.
         
              If telephone instructions are received between 8:30 a.m. and 3:00
     p.m. Eastern time, proceeds of the redemption will be wired in federal
     funds that day to the shareholder's bank account designated on the
     application. Otherwise, shares will be redeemed at the 4:00 p.m. price and
     proceeds will be wired on the next business day. Shares redeemed at the
     3:00 p.m. price do not receive the dividend declared on the day of
     redemption.  Shares redeemed at the 4:00 p.m. price do receive the
     dividends declared on the day of redemption.
        
              Shareholders must designate on their application the U.S.
     commercial bank account or accounts into which they wish the proceeds of
     redemptions from their ^ account in ^ a Portfolio to be deposited. There
     is no charge imposed for wiring of redemption proceeds. A shareholder may
     change the bank account(s) designated to receive amounts redeemed at any
     time by sending a letter of instruction with a signature guarantee to: 
         
              Fidelity Investments Institutional Operations Company (FIIOC)
              Mail Zone ZR5
              P.O. Box 1182
              Boston, MA 02103-1182 

              A signature guarantee is a widely accepted way to protect
     shareholders and FIIOC by verifying the signature on their redemption
     request; it may not be provided by a notary public. Signature guarantees
     will be accepted from: banks, brokers, dealers, municipal securities
     dealers, municipal securities brokers, government securities dealers,
     government securities brokers, credit unions (if authorized under state
     law), national securities exchanges, registered securities associations,
     clearing agencies and savings associations. 

              Further documentation may be required when deemed appropriate by
     FIIOC.
        
              When the ^ New York Stock Exchange (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 Portfolio may suspend redemption or
     postpone payment dates. In addition, the Trust reserves the right to take
     up to seven days to wire redemption proceeds if, in the judgment of FMR,
     the Trust could be adversely affected by making immediate payment.
     Investors unable to execute transactions by telephone (for example, during

                                        - 14 -                        Prospectus

     times of unusual market activity) should consider placing their order by
     mail to FIIOC at the address given above. In case of suspension of the
     right of redemption, investors may either withdraw their request for
     redemption or receive payment based on the NAV next determined after the
     termination of the suspension.
         
        
              INVESTOR ACCOUNTS. FIIOC is the transfer, dividend disbursing and
     shareholder servicing agent for the Trust and maintains an account for
     each investor expressed in terms of full and fractional shares of each
     Portfolio rounded to the nearest 1/1000th of a share. Investments in the
     Portfolios are credited to an investor's account in the form of shares
     immediately upon acceptance as described above, and such shares become
     entitled to dividends declared as of the day of acceptance. The Trust does
     not issue share certificates, but FIIOC mails investors a confirmation of
     each investment or redemption from their account. 
         
              SUBACCOUNTING AND SPECIAL SERVICES. Special processing has been
     arranged with FIIOC for banks, corporations and other institutions that
     wish to open multiple accounts (a master account and subaccounts).  An
     investor wishing to utilize FIIOC's subaccounting facilities or other
     special services for individual or multiple accounts may be required to
     enter into a separate agreement with FIIOC. Charges for these services, if
     any, will be determined on the basis of the level of services to be
     rendered. Subaccounts may be opened with the initial investment or at a
     later date.
        
              ADDITIONAL INFORMATION. All account transactions (including
     purchases, redemptions and exchanges) by telephone through ^  Client
     Services will be recorded. Note that Fidelity will not be responsible for
     any losses resulting from unauthorized transactions if it follows
     reasonable procedures designed to verify the identity of the caller.
     Fidelity will request personalized security codes or other information.
     Investors should verify the accuracy of all transactions immediately upon
     receipt of their confirmation statements. Investors who do not want the
     ability to redeem and exchange by telephone should call Fidelity for
     instructions. 
         
              In order to allow FMR to manage the Portfolios most effectively,
     investors are strongly urged to initiate all trades (investments,
     exchanges and redemptions of shares) as early in the day as possible and
     to notify Client Services at least one day in advance of trades in excess
     of $1 million. In making these trade requests, the name(s) of the
     registered shareholder(s) and the account number(s) must be supplied. To
     protect the Portfolios' performance and shareholders, FMR discourages
     frequent trading in response to short-term market fluctuations.
        
              HOLIDAY SCHEDULE. ^ Each Portfolio is open for business and  ^
     its NAV is calculated ^ each day that both the Federal Reserve Bank of New
     York (New York Fed) and the ^ NYSE are open for trading. The following
     holiday closings have been ^ designated for 1994: Dr. Martin Luther King,
     Jr. Day (observed), Presidents' Day, Good Friday, Memorial Day^,

                                        - 15 -                        Prospectus
<PAGE>






     Independence Day^, Labor Day, Columbus Day, Veterans' Day, Thanksgiving
     Day, and Christmas Day (observed). Although FMR expects the same holiday
     schedule, with the addition of New Year's Day, to be observed in the
     future, the ^ New York Fed or NYSE may modify its holiday schedule at any
     time. ^ The right is reserved to advance the time ^ by which purchase and
     redemption orders must be received on any day (1) that the principal
     government securities markets close early, such as on days in advance of
     holidays generally observed by participants in such markets; (2) that the
     New York Fed or the NYSE closes early; or (3) as permitted by the SEC. To
     the extent that ^ portfolio securities are traded in other markets on days
     ^ that the New York Fed or the NYSE is closed, each Portfolio's NAV may be
     affected on days when investors do not have access to the Portfolios to
     purchase or redeem shares. Certain Fidelity funds may follow different
     holiday ^ schedules.
         
        
              STATEMENTS AND REPORTS. Shareholders will receive a monthly
     statement which details every transaction that affects their share balance
     or account registration. A statement with tax information will be mailed
     to investors by January 31 of each tax year and also will be filed with
     the IRS. At least twice a year investors will receive the Portfolios'
     financial statements.  To reduce expenses, only one copy of the
     Portfolios' reports (such as the ^ Annual Report) may be mailed to each
     shareholder's household. Write to Client Services, at the address given on
     page ^ 10, to have additional reports sent each time.
         
     THE TRUST AND THE FIDELITY ORGANIZATION
        
              U.S. Treasury Portfolio, U.S. Government Portfolio, and Domestic
     Money Market Portfolio are diversified portfolios of Fidelity Money Market
     Trust, an open-end management investment company organized as a ^ Delaware
     business trust by a ^ Trust Instrument dated June 20, 1991. The Trust's
     Board of Trustees supervises Trust activities and reviews its contractual
     arrangements with companies that provide it with services. The Trust is
     not required to hold annual shareholder meetings, although special
     meetings may be called for a specific Portfolio or the Trust as a whole
     for purposes such as electing or removing Trustees, changing fundamental
     policies or limitations or approving a management contract. ^ As a
     shareholder, the number of votes you are entitled to is based upon the
     dollar value of your investment.
         
        
              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, MA. It includes a number of
     different companies which provide a variety of financial services and
     products. The Trust employs various Fidelity companies to perform certain
     activities required for its operation.
         
        
     FMR, the ^ Portfolios' adviser, is the original Fidelity company, founded
     in 1946. FMR provides a number of mutual funds and other clients with

                                        - 16 -                        Prospectus
<PAGE>






     investment research and portfolio management services. FMR maintains a
     large staff of experienced investment personnel and a full complement of
     related support facilities. As of August ^__, 1994, FMR advised funds
     having more than ^ xx million shareholder accounts with a total value of
     more than ^  $xxx billion. FMR has been managing money market funds since
     1974. Fidelity Distributors Corporation (Distributors) distributes shares
     for the Fidelity funds.  FMR Corp. is the parent company for the Fidelity
     companies.  FMR Corp. is the ultimate parent company of FMR and FMR Texas. 
     Through ownership of voting common stock, members of the Edward C. Johnson
     3d ^ family ^ form a controlling group with respect to FMR Corp.  Changes
     may occur in the Johnson family group, through death or disability, which
     would result in changes in each individual family members' holding of
     stock.  Such changes could result in one or more family members becoming
     holders of over 25% of the stock.  FMR Corp. has received an opinion of
     counsel that changes in the composition of the Johnson family group under
     these circumstances would not result in the termination of the Portfolios'
     management or distribution contracts and, accordingly, would not require a
     shareholder vote to continue operation under those contracts.
         
     MANAGEMENT CONTRACTS, DISTRIBUTION AND SERVICE PLANS

              Management Contracts. FMR manages each Portfolio's investments
     and business affairs, and pays the Portfolio's expenses with the following
     exceptions: the fees and expenses of those Trustees who are not
     "interested persons" of the Trust or FMR; brokerage fees or commissions
     (if any); interest on borrowings; taxes; and such extraordinary
     non-recurring expenses as may arise, including litigation to which the
     Trust may be a party. Transfer agent and dividend disbursing services are
     provided by FIIOC, and portfolio and general accounting record maintenance
     are provided by Service. The costs of these services are borne by FMR
     pursuant to its Management Contract with each Portfolio. Both FIIOC and
     Service are affiliates of FMR.
        
              Each Portfolio pays FMR a monthly management fee at the annual
     rate of 0.42% of its average net assets throughout the month. For the
     fiscal year ended August 31, ^ 1994, management fees before reduction for
     compensation, including reimbursement of expenses, to non-interested
     Trustees, for the U.S. Treasury Portfolio, U.S. Government Portfolio, and
     Domestic Money Market Portfolio amounted to ^ $_______, $_________, and
     $_________, respectively.
         
        
              FMR has entered into a sub-advisory agreement with FMR Texas 
     Inc. (FMR Texas) under which FMR Texas has primary responsibility for
     providing portfolio investment management services to each Portfolio while
     FMR retains responsibility for providing other management services.  Under
     each ^ sub-advisory agreement, FMR pays FMR Texas a fee equal to 50% of
     the management fee payable to FMR under its current management contract
     with ^ the applicable Portfolio.  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.

              Total expenses for the fiscal year ended August 31, ^ 1994 were
     ^__% of average net assets for each Portfolio.
         
        
              DISTRIBUTION AND SERVICE PLAN.  ^ The Board of Trustees, on
     behalf of each Portfolio has adopted a Distribution and Service Plan (the
     Plans) pursuant to Rule 12b-1 ^ of the 1940 Act (the Rule).  Each Plan
     specifically recognizes that FMR, either directly or through Distributors,
     may use its management fee revenues, past profits or other resources,
     without limitation, to pay promotional and administrative expenses in
     connection with the offer and sale of shares of the Portfolios. In
     addition, each Plan provides that FMR may use its resources, including its
     management fee revenues, to make payments to third parties that provide
     assistance in selling shares of the Portfolios or to third parties,
     including banks, that render shareholder support services. The Board of
     Trustees has authorized compensation to third parties under the ^ Plans at
     an annual rate of .08% annually of the average net assets of each
     Portfolio with respect to which they provide or have provided shareholder
     support or distribution services. No separate payments are authorized to
     be made by the Portfolios under the Plans.
         
              Each Portfolio also has a Distribution Agreement with
     Distributors, a wholly-owned subsidiary of FMR Corp. Distributors, a
     Massachusetts corporation organized July 18, 1960, is a broker- dealer
     registered under the Securities Exchange Act of 1934 and a member of the
     National Association of Securities Dealers, Inc. The Distribution
     Agreement calls for Distributors to use all reasonable efforts, consistent
     with its other business, to secure purchasers for shares of each
     Portfolio, which are continuously offered. Promotional and administrative
     expenses in connection with the offer and sale of shares are paid by FMR.
     Distributors also acts as distributor for other Fidelity funds. The
     expenses of these operations are borne by FMR or Distributors.

     ^                                 APPENDIX

              The following paragraphs provide a brief description of the
     securities in which the Portfolios may invest and the transactions they
     may make. The Portfolios are not limited by this discussion, however, and
     they may purchase other types of securities and enter into other types of
     transactions if they are consistent with the Portfolios' investment
     objectives and policies.
        
              A complete listing of the Portfolios' policies and limitations
     and more detailed information about the Portfolios' investments are
     contained in the Portfolios' SAI.  Current holdings and recent investment
     strategies are described in the Portfolios' financial report, which is
     sent to shareholders twice a year.
         
        
     ASSET BACKED SECURITIES ^ may 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.
         
        
     BANKERS' ACCEPTANCES ^ are negotiable obligations of a bank to pay a draft
     which has been drawn on it by a customer. These obligations are drawn on
     large banks and usually backed by goods in international trade.
         
        
     CERTIFICATES OF DEPOSIT ^ are negotiable certificates representing a
     commercial bank's obligations to repay funds deposited with it, earning
     special rates of interest over a given period of time.
         
        
     COMMERCIAL PAPER ^ are short-term obligations issued by banks,
     broker-dealers, corporations and other entities for purposes such as
     financing their current operations.
         
     DELAYED DELIVERY TRANSACTIONS. The Portfolios may buy and sell securities
     on a when-issued or delayed delivery basis, with payment and delivery
     taking place at a future date. The market value of securities purchased in
     this way may change before the delivery date, which could affect the
     market value of the Portfolios' assets. Ordinarily, the Portfolios will
     not earn interest on securities until they are delivered.
        
     ILLIQUID INVESTMENTS.^  Under the supervision of the Board of Trustees,
     FMR determines the liquidity of each Portfolio's investments. The absence
     of a trading market can make it difficult to ascertain a market value for
     illiquid investments.   ^ Disposing of illiquid investments may involve
     time-consuming negotiation and legal expenses, and it may be difficult or
     impossible for ^ the Portfolios to sell ^ illiquid investments promptly at
     an acceptable price.

        INTERFUND BORROWING PROGRAM. The Portfolios have received permission
     from the SEC to lend money to and borrow money from other funds advised by
     FMR or its affiliates. Interfund loans and borrowings normally will extend
     overnight, but can have a maximum duration of seven days.  ^ U.S. Treasury
     Portfolio and ^ U.S. Government Portfolio will participate in this program
     only as borrowers and each portfolio will borrow through the program only
     when the costs are equal to or lower than the cost of bank loans. ^
     Domestic Money Market Portfolio will lend through the program only when
     the returns are higher than those available at the same time from other
     short-term instruments (such as repurchase agreements), and will not lend
     more than 10% of its assets to other funds. 
         
        
     A Portfolio will not borrow through the program if, after doing so, total
     outstanding borrowings immediately after such borrowings would exceed 15%
     of its total assets. Loans may be called on one day's notice, and Domestic
     Money Market Portfolio 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 Domestic Money Market Portfolio could result in a lost investment
     opportunity or additional borrowing costs.
     ^
         
        
     MUNICIPAL OBLIGATIONS ^ are issued to raise money for various public
     purposes, including general purpose financing ^ for state and local
     governments as well as financing for specific projects or public
     facilities. Municipal obligations may be backed by the full taxing power
     of a municipality or by the revenues from a specific project or the credit
     of a private organization.
         
        
     REPURCHASE AGREEMENTS ^.  In a repurchase agreement, a Portfolio buys a
     security at one price and simultaneously agrees to sell it back at a
     higher price. In the event of the bankruptcy of the other party to a
     repurchase agreement, a Portfolio could experience delays in recovering
     its cash.  To the extent that, in the meantime, the value of the
     securities purchased ^ had decreased, the Portfolio could experience a
     loss.  In all cases,  FMR must find the creditworthiness of the other
     party to ^ the transaction ^ satisfactory ^.  
         
        
     RESTRICTED ^ SECURITIES ^ cannot be sold to the public without
     registration under the Securities Act of 1933. Unless registered for sale,
     these securities can only be sold in privately negotiated transactions or
     pursuant to an exemption from registration.
         
     REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, a
     Portfolio sells a portfolio instrument to another party, such as a bank or
     broker-dealer, in return for cash. At the same time, a Portfolio agrees to
     repurchase the instrument at a particular price and date. A Portfolio
     expects that it will engage in reverse repurchase agreements for temporary
     purposes such as to fund redemption requests, or when it is able to invest

                                        - 20 -                        Prospectus
<PAGE>






     the cash so acquired at a rate higher than the cost of the agreement,
     which would increase the income earned by a Portfolio. Reverse repurchase
     agreements may increase the risk of fluctuation in the market value of a
     Portfolio's assets or in its yield.

     STRIPPED GOVERNMENT SECURITIES. Stripped securities are created by
     separating the income and principal components of a debt instrument and
     selling them separately. Each Portfolio may purchase U.S. Treasury STRIPS
     (Separate Trading of Registered Interest and Principal of Securities),
     that are created when the coupon payments and the principal payment are
     stripped from an outstanding Treasury bond by the Federal Reserve Bank of
     New York.
        
     TIME DEPOSITS are non-negotiable deposits in a banking institution earning
     a specified interest rate over a given period of time.
         
        
     VARIABLE OR FLOATING RATE OBLIGATIONS provide for periodic adjustments of
     the interest rates paid.  Floating rate obligations have interest rates
     that change whenever there is a change in a designated base rate, while
     variable rate obligations provide for a specified periodic adjustment in
     the interest rate.  These formulas are designed to result in a market
     value for the instrument that approximates its par value ^.  When
     determining the maturity of a variable or floating rate ^ obligation, a
     Portfolio may look to the date the demand feature can be exercised, or to
     the date the interest rate is readjusted, rather than to the final ^
     maturity of the ^ o1

     INVESTMENT 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 a Portfolio'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 shall
     be determined immediately after and as a result of the Portfolio'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 ^ a Portfolio's
     investment policies and limitations.  
         
        
              Each Portfolio's fundamental investment policies and limitations
     may not 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 Portfolio.  However, except for the fundamental investment
     limitations set forth below, the investment policies and limitations
     described in this ^ SAI are not fundamental and may be changed without
     shareholder approval.  THE FOLLOWING ARE EACH PORTFOLIO'S INVESTMENT
     LIMITATIONS SET FORTH IN THEIR ENTIRETY.
         
          Fundamental Investment Limitations of the U.S. Treasury Portfolio
          ----------------------------------------------------------------

     The Portfolio may not:
        
     1.       with respect to 75% of the Portfolio's total assets, purchase the
     securities of any issuer (other than ^ securities issued or guaranteed as
     to principal ^ by the U.S. government or any of ^ its agencies or

     section entitled "Quality and Maturity" on page 11.
         
        
              AFFILIATED BANK TRANSACTIONS.  ^ A Portfolio may engage in
     transactions with financial institutions that are, or may be considered to
     be, "affiliated persons" of the Portfolios 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
     SEC, the Board of Trustees has established and periodically reviews
     procedures applicable to transactions involving affiliated financial
     institutions.

              ASSET-BACKED SECURITIES ^ may include interests in pools of
     mortgages, loans, ^ receivables, or other assets.  Payment of principle
     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 financial institution(s) providing the credit support.
         
              DELAYED DELIVERY TRANSACTIONS.  The Portfolios may buy and sell
     securities on a delayed delivery or when-issued basis.  These transactions
     involve a commitment by the Portfolios to purchase or sell specific
     securities at a predetermined price and/or yield, with payment and
     delivery taking place after the customary settlement period for that type
     of security (and more than seven days in the future).  Typically, no
     interest accrues to the purchaser until the security is delivered.
        
              When purchasing securities on a delayed delivery basis, a
     Portfolio assumes the rights and risks of ownership, including the risk of
     price and yield fluctuations.  Because a Portfolio is not required to pay
     for securities until the delivery date, these risks are in addition to the
     risks associated with each Portfolio's other investments.  If a Portfolio
     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, a
     Portfolio will set aside appropriate liquid assets in a segregated
     custodial account to cover its purchase obligations.  When a Portfolio has
     sold a security on a delayed delivery basis, the Portfolio 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, ^ a Portfolio could miss a favorable price or yield
     opportunity, or could suffer a loss.
         
              The Portfolios may renegotiate delayed delivery transactions
     after they are entered into, and may sell underlying securities before
     they are delivered, which may result in a 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 ^ a Portfolio's investments and, through
     reports from FMR, the Board monitors investments in illiquid instruments. 
     In determining the liquidity of ^ a Portfolio'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 Portfolio's rights and obligations relating to the investment).
     Investments currently considered to be illiquid include repurchase
     agreements not entitling the holder to payment of principal and interest
     within seven days.  Also, with respect to Domestic Money Market Portfolio,

                                        - 13 -
<PAGE>






     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 Portfolio were in a position where 10% or more of its
     net assets were invested in illiquid securities, it would seek to take
     appropriate steps to protect liquidity.
         
        
              QUALITY AND MATURITY.  Pursuant to procedures adopted by the
     Board of Trustees, the Portfolios may purchase only high-quality
     securities that FMR believes present minimal credit risks.  To be
     considered high-quality, a security must be a U.S. government security;
     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 have received the highest
     rating (e.g. Standard & Poor's A-1 rating) from at least two rating
     services (or one, if only one has rated the security).  Second tier
     securities have received ratings within the two highest rating categories
     (e.g. Standard & Poor's A-1 or A-2) from at least two rating services (or
     one, if only one has rated the security), but do not qualify as first tier
     securities.  If a security has been assigned different ratings by
     different ratings services, at least two rating services must have
     assigned the higher rating in order for FMR to determine eligibility in
     the basis of that higher rating.  Based on procedures adopted by the Board
     of Trustees, FMR may determine that an unrated security is of equivalent
     quality to a rated first or second tier security.
         
        
              Domestic Money Market Portfolio may not invest more than 5% of
     its total assets in second tier securities.  In addition, the Domestic
     Money Market Portfolio 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 Portfolios currently intend to limit their investments to
     securities with remaining maturities of 397 days or less, and to maintain
     a dollar-weighted average maturity of 90 days or less.
         
        
              REPURCHASE AGREEMENTS.  In a repurchase agreement, a Portfolio
     purchases a security and simultaneously commits to resell that security to
     the 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.  A repurchase

                                        - 14 -
<PAGE>






     agreement involves the obligation of the seller to pay the agreed-upon 
     resale price, which obligation is in effect secured by the value (at least
     equal to the amount of the agreed-upon resale price and marked to market
     daily) of the underlying security.  ^ A Portfolio may engage in repurchase
     agreements with respect to any type of security in which it is authorized
     to invest (except that the security may have a maturity in excess of 397
     days).  While it does not presently appear possible to eliminate all risks
     from these transactions (particularly the possibility of a decline in the
     market value of the underlying securities, as well as delays and costs to
     ^ a Portfolio in connection with bankruptcy proceedings), it is ^ each
     Portfolio's current policy to limit repurchase agreement transactions to
     those 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 Portfolio 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
     Portfolio might obtain a less favorable price than prevailed when it
     decided to seek registration of the security.  However, in general, the
     Portfolio anticipates holding restricted securities to maturity or selling
     them in an exempt transaction.
         
        
              REVERSE REPURCHASE AGREEMENTS.  In a reverse repurchase
     agreement, a Portfolio sells a portfolio instrument to another party, such
     as a bank or 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, ^ a Portfolio will maintain appropriate liquid
     assets in a segregated custodial account to cover its obligation under the
     agreement.  ^ A Portfolio 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 ^
     a Portfolio's assets and may be viewed as a form of leverage.
         
        
              ^ Short Sales Against the Box.  A Portfolio 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 a Portfolio in anticipation
     of increased interest rates without sacrificing the current yield of the
     securities sold short.  If a Portfolio 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.  A Portfolio


                                        - 15 -
<PAGE>






     will incur transaction costs, including interest expenses, in connection
     with opening, maintaining and closing short sales against the box.
         
        
              ^ Stripped Government Securities are created by separating the
     income and principal components of a debt instrument and selling them
     separately.  Each Portfolio may purchase U.S. Treasury STRIPS (Separate
     Trading of Registered Interest and Principal of Securities), that 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 Resolution Funding Corporation (REFCORP) can also be
     stripped in this fashion.  REFCORP Strips are eligible investments for the
     Portfolios.
         
        
              Domestic Money Market Portfolio can purchase privately stripped
     government securities, which 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 Financing
     Corporation (FICO) can also be stripped in this fashion.
         
        
              Because of the SEC's views on privately stripped government
     securities, Domestic Money Market Portfolio must evaluate them as it would
     non-government securities pursuant to regulatory guidelines applicable to
     all money market funds. Accordingly, the Portfolio 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, been judged
     to be of equivalent quality by FMR pursuant to procedures adopted by the
     Board of Trustees.
         
        
              ^ Variable or Floating Rate Demand Obligations provide for
     periodic adjustments of the interest rate paid.  Floating rate obligations
     have interest rates that change whenever there is a change in a designated
     base rate while variable rate obligations provide for a specified periodic
     adjustment in the interest rate.  These formulas are designed to result in
     a market value for the instrument that approximates its par value.
         
        
              ^ Some variable or floating rate ^ obligations permit holders to
     demand payment of the unpaid principal balance plus an accrued interest
     from the issuers or certain financial intermediaries.  Issuers or
     financial intermediaries who provide demand features or stand-by
     commitments often obtain letters of credit (LOCs) or other guarantees from
     domestic or foreign banks to support their repurchase commitments.  FMR

                                        - 16 -
<PAGE>






     may rely upon its evaluation of a bank's credit in determining whether to
     purchase an obligation supported by an LOC.  In evaluating a foreign
     bank's credit, FMR will consider whether adequate public information about
     the bank is available and whether the bank may be subject to unfavorable
     political or economic developments, currency controls, or other
     governmental restrictions that might affect the bank's ability to honor
     its credit commitment.
         
        
              When determining the maturity of a variable or floating rate
     obligation, a Portfolio may look to the date the demand feature can be
     exercised, or to the date the interest rate is readjusted, rather than to
     the final maturity of the obligation.
         
     PORTFOLIO TRANSACTIONS
        
              All orders for the purchase or sale of portfolio securities are
     placed on behalf of ^ each Portfolio by FMR pursuant to authority
     contained in the ^ management contract.  If FMR grants investment
     management authority to the sub-adviser (see the section entitled
     "Management Contracts"), the sub-adviser will be 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 Portfolios 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 Portfolios may execute portfolio transactions with
     broker-dealers who provide research and execution services to the ^
     Portfolios 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; the availability of securities or the purchasers or
     sellers of securities; furnishing analyses and reports concerning issuers,
     industries, securities, economic factors and trends, portfolio strategy
     and performance of accounts; and effecting securities transactions and
     performing 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 Portfolios 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

                                        - 17 -
<PAGE>






     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 Portfolios may be useful to FMR in rendering
     investment management services to the Portfolios ^ 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 Portfolios.  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 Portfolios 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 Portfolios 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 Portfolios 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, Ltd.
     (FBSL), subsidiaries of FMR Corp., if the commissions are fair ^,
     reasonable, and comparable to commissions charged by ^  non-affiliated,
     qualified brokerage firms for similar services. 
         
        
              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.
         
        


                                        - 18 -
<PAGE>






              The Trustees periodically review FMR's performance of its
     responsibilities in connection with the placement of portfolio
     transactions on behalf of ^ the Portfolios and review the commissions paid
     by each Portfolio over representative periods of time to determine if they
     are reasonable in relation to the benefits to each Portfolio.
         
        
              From time to time the Trustees will review whether the recapture
     for the benefit of the Portfolios of some portion of the brokerage
     commissions or similar fees paid by ^ the Portfolios on portfolio
     transactions is legally permissible and advisable.  ^ Each Portfolio 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
     each Portfolio to seek such recapture.
         
        
              Although the Trustees and officers of ^ each Portfolio are
     substantially the same as those of other funds managed by FMR, investment
     decisions for ^ each Portfolio 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 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 Portfolio. In some cases this system could have a detrimental effect
     on the price or ^ value of the security as far as ^ each Portfolio is
     concerned.  In other cases, however, the ability of the ^ Portfolios to
     participate in volume transactions will produce better executions and
     prices for the ^ Portfolios.  It is the current opinion of the Trustees
     that the desirability of retaining FMR as investment adviser to ^ each
     Portfolio outweighs any disadvantages that may be said to exist from
     exposure to simultaneous transactions.
         
     VALUATION OF PORTFOLIO SECURITIES
        
              Each Portfolio values its investments on the basis of amortized
     cost.  This technique involves valuing an instrument at its cost as
     adjusted for amortization of premium or accretion of discount rather than
     its value based on current market quotations or appropriate substitutes
     which reflect current market conditions.  The amortized cost value of an
     instrument may be higher or lower than the price the ^ Portfolio would
     receive if it sold the instrument.
         

                                        - 19 -
<PAGE>






        
              Valuing each Portfolio's instruments on the basis of amortized
     cost and use of the term "money market fund" are permitted by Rule 2a-7
     under the 1940 Act.  The Portfolio must adhere to certain conditions under
     Rule 2a-7; these conditions are summarized in the Prospectus.
         
        
              The Board of Trustees of the Trust oversees FMR's adherence to
     SEC rules concerning money market funds, and has established procedures
     designed to stabilize each Portfolio's net asset value per share (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 Portfolio'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.
         
        
              During periods of declining interest rates, ^ a Portfolio's yield
     based on amortized cost may be higher than the yield based on market
     valuations.  Under these circumstances, a shareholder in the Portfolio
     would be able to obtain a somewhat higher yield than would result if the
     Portfolio utilized market valuations to determine its NAV.  The converse
     would apply in a period of rising interest rates.
         
     PERFORMANCE
        
              From time to time each Portfolio ^ advertises its yield and
     effective yield in advertisements or in reports or other communications
     with shareholders.  Both yield figures are based on historical earnings
     and are not intended to indicate future performance.  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. 
     This income is then annualized.  That is, the amount of income generated
     by the investment during that week is assumed to be generated each week
     over a 52-week period and is shown as a percentage of the investment.  The
     effective yield is calculated similarly but, when annualized, the income
     earned by an investment in each Portfolio is assumed to be reinvested. 
     The effective yield will be slightly higher than the yield because of the
     compounding effect of this assumed reinvestment.  In addition to the
     current yield, the Portfolios may quote yields in advertising based on any
     historical seven day period.

              Yield information may be useful in reviewing each Portfolio's
     performance and for providing a basis for comparison with other investment
     alternatives.  Each Portfolio's yield will fluctuate, unlike investments
     which pay a fixed yield for a stated period of time.^
         
              TOTAL RETURN CALCULATIONS:  Total returns quoted in advertising
     reflect all aspects of a Portfolio's return, including the effect of
     reinvesting dividends and capital gain distributions (if any).  Average
     annual returns are calculated by determining the growth or decline in
     value of a hypothetical historical investment in a Portfolio over a stated
     period and then calculating the annually compounded percentage rate that
     would have produced the same results if the rate of growth or decline in
     the value of the investment had been constant over that period.  For
     example, a cumulative return of 100% over ten years would produce an
     average annual return of 7.18%, which is the steady annual rate that would
     equal 100% growth on a compounded basis in ten years.  While average
     annual returns are a convenient means of comparing investment
     alternatives, investors should realize that a Portfolio's performance is
     not constant over time, but changes from year to year, and that average
     annual returns represent averaged figures as opposed to the actual
     year-to-year performance of a Portfolio.
        
              In addition to average annual returns, a Portfolio may quote
     unaveraged or cumulative total returns reflecting the simple change in the
     value of an investment over a stated period.  Average annual and
     cumulative total returns may be quoted as percentages or as dollar amounts
     and may be calculated for a single investment, as 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 in order to illustrate
     the relationship of these factors and their contributions to total return. 
     Total returns, yields, and other performance information may be quoted
     numerically or in a table, graph, or similar illustration.  Each
     Portfolio's cumulative total returns and average annual returns for the
     fiscal year ended August 31, ^ 1994 were as follows:

       EXPLANATORY NOTES:  With an initial investment of $10,000 made on
     October 31, 1984, the net amount invested in shares of each Portfolio was
     $10,000.  The cost of the initial investment ($10,000) together with the
     aggregate cost of reinvested dividends from October 31, 1984 through
     August 31, ^ 1994 for U. S. Treasury Portfolio, U.S. Government Portfolio
     and Domestic Money Market Portfolio (that is, their cash value at the time
     they were reinvested) amounted to ^ $______, $______ and ^  $______,
     respectively.  If distributions had not been reinvested, the amount of
     distributions earned from each Portfolio over time would have been
     smaller, and the cash payments (dividends) for the period would have
     amounted to ^  $_____, $_____ and ^ $_____ for U. S. Treasury Portfolio,
     U.S. Government Portfolio and Domestic Money Market Portfolio,
     respectively.  The Portfolios did not distribute any capital gains during
     these periods.
         
        
              The Portfolios may compare their performance or the performance
     of securities in which they may invest to averages published by IBC USA
     (Publications), Inc. of Ashland, Massachusetts.  These averages assume
     reinvestment of distributions.  The MONEY FUND AVERAGES)(REGISTERED
     TRADEMARK)/Total Institutions-Only Average; Government - Only;
     Institutions - Only; First Tier Institutions - Only; and Second Tier
     Institutions - Only, which are reported in the MONEY FUND REPORT^, covers
     over 172 taxable money market funds.  When evaluating comparisons to money
     market funds, investors should consider the relevant differences in
     investment objectives and policies.  Specifically, money market funds
     invest in short-term, high-quality instruments and seek to maintain a
     stable $1.00 share price.

              A Portfolio'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 which 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 the funds based
     on yield.  In addition to the mutual fund rankings, a Portfolio's
     performance may be compared to mutual fund performance indices prepared by
     Lipper.  The Portfolios may compare their performance to the  yields on
     other money market securities or averages of other money market securities
     as reported by the Federal Reserve Bulletin, by TeleRate, a financial
     information network, or by Salomon Brothers Inc., a broker-dealer firm;
     and on other fixed-income investments such as Certificates of Deposit
     (CDs).

              The principal value and interest rate of CDs and money market
     securities are fixed at the time of purchase, whereas each Portfolio's
     yield will fluctuate.  Unlike some CDs and certain other money market
     securities, money market mutual funds are not insured by the FDIC. 
     Investors should give consideration to the quality and maturity of the
     portfolio securities of the respective investment companies when comparing
     investment alternatives.

              The Portfolios may reference the growth and variety of money
     market mutual funds and the adviser's innovation and participation in the
     industry.

              Each Portfolio may reference and discuss its fund number,
     Quotron(REGISTERED TRADEMARK) number, CUSIP number, and current portfolio
     manager in advertising.
        
              IBBOTSON.  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.

              MORNINGSTAR.  From time to time, in reports and promotional
     literature, a Portfolio's performance also may be compared to other mutual
     funds tracked by financial or business publications and periodicals.  For
     example, a Portfolio may quote Morningstar, Inc. in its advertising
     materials.  Morningstar, Inc. is a mutual fund rating service that rates
     mutual funds of the basis or risk-adjusted performance.  In addition, a
     Portfolio may quote financial or business publications and periodicals as
     they relate to fund management, investment philosophy, and investment
     techniques.  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.

     ADDITIONAL PURCHASE 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 a Portfolio'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, each Portfolio 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
     exchange, or (ii) if the Portfolio temporarily 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.

              The Portfolios have notified shareholders that they reserve the
     right at any time, without prior notice, to refuse exchange purchases by
     any person or group if, in FMR's judgment, a Portfolio would be unable to
     invest effectively in accordance with its investment objective and
     policies or might otherwise be adversely affected. 

     DISTRIBUTIONS AND TAXES
        
              DIVIDENDS.  Dividends from each Portfolio will not normally
     qualify for the dividends-received deduction available to corporations,
     since the Portfolios' income is primarily derived from interest income and
     short-term capital gains.  Depending upon state law, a portion of each
     Portfolio's dividends attributable to interest income derived from U.S. ^
     government securities may be exempt from state and local taxation.  The
     Portfolios will provide information on the portion of a Portfolio's
     dividends, if any, that qualify for this exemption.

              CAPITAL GAIN DISTRIBUTIONS. The Portfolios may distribute
     short-term capital gains once a year or more often as necessary to
     maintain their NAVs at $1.00 per share or to comply with distribution
     requirements under federal tax law.  The Portfolios do not anticipate
     earning long-term capital gains on securities held by a Portfolio.

              TAX STATUS OF FUND.  Each Portfolio has qualified and intends to
     qualify as a "regulated investment company" under the Internal Revenue
     Code of 1986, as amended (the Code), so that a Portfolio will not be
     liable for federal income or excise taxes on net investment income or
     capital gains to the extent that these are distributed to shareholders in
     accordance with applicable provisions of the Code.
        
              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 pass through 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 pass-through benefit.  The tax
     treatment of your dividend distributions from U.S. Treasury Portfolio and
     U.S. Government Portfolio will be the same as if you directly owned your
     proportionate share of the U.S. government securities in each Portfolio's
     portfolio.  Because the income earned on most U.S. government securities
     in which U.S. Treasury Portfolio and U.S. Government Portfolio invest is
     exempt form state and local taxes, the portion of your dividends from the
     Portfolios 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.

     each Portfolio.  These services include providing facilities for
     maintaining each Portfolio's organization, supervising relations with the

     shareholder communications and conducting shareholder relations,

     shares under federal and state securities laws, developing management and
     shareholder services for each Portfolio and furnishing reports,
     evaluations and analyses on a variety of subjects to the Trustees.
         
              FMR pays all the expenses of the Trust as described herein. 
     Specific expenses payable by FMR include, without limitation, the fees and

     typesetting for printing prospectuses; custodian charges; auditing and
     legal expenses; insurance expense; association membership dues; the
     expense of reports to shareholders; shareholder meetings; and proxy
     solicitations.
          

              FIIOC ^ is transfer ^, dividend disbursing, and shareholder
     servicing ^ agent for ^ the Portfolios.  The costs of ^ these services are
     borne by FMR pursuant to its ^ management contract with each Portfolio. 
     Service calculates each Portfolio's NAV and dividends, and maintains ^
     each Portfolio's general accounting records. The costs of these services
     are also borne by FMR pursuant to its management contract with each
     Portfolio.^
         
        
              FMR pays all other expenses of the ^ Portfolios with the
     following exceptions:  the payment of fees and expenses of all Trustees of

     fees or commissions (if any); interest on borrowings; taxes; and such
     extraordinary non-recurring expenses as may arise, including costs of
     litigation to which the ^ Portfolios may be a party, and any obligation a
     Portfolio may have to indemnify its officers and Trustees with respect to
     litigation.
         
     For these services and the payment by FMR of the Trust's expenses, each
     Portfolio pays a monthly management fee to FMR at the annual rate of .42%
     of the average net assets of the Portfolio throughout the month pursuant
     to a Management Contract approved by the shareholders on October 30, 1986. 
     The management fees paid to FMR are reduced by an amount equal to the fees

              The Portfolios have a Distribution Agreement with Distributors, a
     Massachusetts corporation organized on July 18, 1960.  Distributors is a
     broker-dealer registered under the Securities and Exchange Act of 1934 and
     is a member of the National Association of Securities Dealers, Inc.  The
     Distribution Agreement calls for Distributors to use all reasonable
     efforts, consistent with its other business, to secure purchasers for
     shares of the Portfolios, which are continuously offered.  Promotional and
     administrative expenses in connection with the offer and sale of shares
     are paid by FMR.
         
     DISTRIBUTION AND SERVICE PLANS
        
              Each Portfolio has adopted a Distribution and Service Plan (the
     Plans) 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 the ^ fund except pursuant to a plan adopted by
     the ^ fund under the Rule.  The Trust's Board of Trustees has adopted ^
     the Plans to  ^ allow each Portfolio and FMR ^ to incur certain expenses
     that might be considered to constitute indirect payment by ^ the Portfolio
     of distribution expenses.  Under ^ each Plan, if the payment of management
     fees by a Portfolio to FMR ^ is deemed ^ indirect financing by the
     Portfolio of the distribution of its shares, such payment is authorized by
     the Plan.
         
        
              ^ Each Plan specifically ^ recognizes that FMR, either directly
     or through Distributors, may use its management fee revenue, past profits,
     or other resources, without limitation, to pay promotional and
     administrative expenses in connection with the offer and sale of shares of
     ^ a Portfolio.  In addition, ^ each Plan provides that FMR may use its
     resources, including its management fee revenues, to make payments to


                                        - 34 -
<PAGE>






     third parties that provide assistance in selling shares of the ^ 
     Portfolio, or to third parties, including banks, that render shareholder
     support services.  The Board of Trustees has authorized such payments.
         
        
              As required by the Rule, the Trustees carefully considered all
     pertinent factors relating to the implementation of ^ each Plan prior to ^
     its approval, and have determined that there is a reasonable likelihood
     that the ^ Plan will benefit the ^  Portfolio and ^ its shareholders.  In
     particular, the Trustees noted that none of the Plans ^ authorizes
     payments by the Portfolios other than those made to FMR under ^ its
     management contract with such Portfolio.  To the extent that ^ each Plan
     gives FMR and Distributors greater flexibility in connection with the
     distribution of shares of the ^ applicable Portfolio, additional sales of
     each Portfolio's shares may result. Additionally, certain shareholder
     support services may be provided more effectively under ^ each Plan by
     local entities with whom shareholders have other relationships.  Each Plan
     was approved by Fidelity Money Market Trust on September 21, 1994, as the
     then sole shareholder of each Portfolio, pursuant to an Agreement and Plan
     of Conversion approved by public shareholders of the Portfolios on
     September 21, 1994 ^.
         
        
              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, Distributors believes
     that the Glass Steagall Act should not preclude a bank from performing
     shareholder support services, or servicing and recordkeeping functions. 
     Distributors 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 Portfolios 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 financial institutions may be required to
     register as dealers pursuant to state law.  
         
        
              ^ Each Portfolio may execute portfolio transactions with and
     purchase securities issued by depository institutions that receive
     payments under ^ its Plan.  No preference for the instruments of such
     depository institutions will be shown in the selection of investments ^.

     DESCRIPTION OF THE TRUST
        
              U.S. Treasury Portfolio, U.S. Government Portfolio and Domestic
     Money Market Portfolio ^ are portfolios of Fidelity Money Market Trust, an
     open-end management investment company  originally organized as a
     Massachusetts business trust by Declaration of Trust dated August 21, 1978
     ^ and amended and restated ^ November 1, 1989.  On October 18, 1994 the
     Trust was converted to a Delaware business trust pursuant to an agreement
     approved by shareholders on September 21, 1994.  The Delaware trust, which
     was organized on June 20, 1991, under the name of Fidelity Money Market
     Trust I, succeeded to the name Fidelity Money Market Trust on October 18,
     1994. Currently, there are five portfolios of the Trust: U.S. Treasury
     Portfolio, U.S. Government Portfolio, Domestic Money Market Portfolio,
     Retirement Money Market Portfolio, and Retirement Government Money Market
     Portfolio.
     The Trust Instrument permits the Trustees to create additional series.
         
        
              In the event that FMR ceases to be the investment adviser to the
     Trust or a Portfolio, the right of the Trust or ^  portfolio to use the
     identifying name "Fidelity" may be withdrawn.  There is a remote
     possibility that one Portfolio might become liable for any misstatement in
     its prospectus or statement of additional information about another
     Portfolio. 
         
        
              The assets of the Trust, received for the issue or sale of shares
     of each ^ portfolio and all income, earnings, profits, and proceeds
     thereof, subject only to the rights of creditors, are especially allocated
     to such ^ portfolio, and constitute the underlying assets of such ^
     portfolio.  The underlying assets of each ^ portfolio are segregated on
     the books of account, and are to be charged with the liabilities with
     respect to such ^  portfolio 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 ^ portfolios, 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 ^
     portfolio, or which are general or allocable to all of the ^ portfolios. 
     In the event of the dissolution or liquidation of the Trust, shareholders
     of each ^ portfolio are entitled to receive as a class the underlying
     assets of such ^ portfolio 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

                                        - 36 -
<PAGE>






     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 ^ portfolio's
     property of any ^ shareholder or former shareholder held personally liable
     for the obligations of the ^  portfolio.  The Trust Instrument also
     provides that each ^  portfolio shall, upon request, assume the defense of
     any claim made against any shareholder for any act or obligation of the ^ 
     portfolio 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 a portfolio is
     unable to meet its obligations.  FMR believes that, in view of the above,
     the risk of personal liability to shareholders is remote.
         
        
              The ^ Trust Instrument further provides that the Trustees, if
     they have exercised reasonable care, will not be liable ^ to any person
     other than the Trust or its shareholders; moreover, the Trustees shall not
     be liable for any conduct whatsoever provided that the Trustees are not
     protected against any liability to which ^ they would otherwise would 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 ^ portfolio's capital consists of shares of
     beneficial interest.  As a shareholder, you receive one vote for each
     dollar of net asset value 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 ^ portfolio may, as set forth
     in the ^ Trust Instrument, call meetings of the Trust or a ^ portfolio for
     any purpose related to the Trust or ^  portfolio, 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 ^ portfolio
     may be terminated upon the sale of its assets to, or merger with, another
     open-end management investment company, 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 portfolio, as
     determined by the current value of each shareholder's investment in the
     portfolio 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 ^ each portfolio 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's registration

     investment company.

              CUSTODIAN.  Morgan Guaranty Trust Company of New York, 60 Wall
     Street, New York, NY, is custodian of the assets of the ^  Portfolios. 
     The custodian is responsible for the safekeeping of the ^ Portfolios'
     assets and the appointment of subcustodian banks and clearing agencies. 
     The custodian takes no part in determining the investment policies of the
     ^ Portfolios or in deciding which securities are purchased or sold by the
     ^  Portfolios.  The Portfolios may, however, invest in obligations of the
     custodian and may purchase securities from or sell securities to the
     custodian.
         
              FMR, its officers and directors, its affiliated companies, and
     the Trust's Trustees may from time to time have transactions with various
     banks, including banks serving as custodians for certain of the 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 Trust relationships.
        
              AUDITOR.  ^___________________, serves as the Trust's independent
     accountant.  The auditor examines financial statements for the ^
     Portfolios and provides other audit, tax and related services.
         
     FINANCIAL STATEMENTS
        
              Each Portfolio's ^ financial statements and financial highlights
     for the fiscal year ended August 31, ^ 1994 are included in the
     Portfolios' Annual Report, which is a separate report ^ attached to the
     Prospectus.  Each Portfolio's financial statements and financial
     highlights are incorporated herein by reference.
         
     APPENDIX

              The descriptions that follow are examples of eligible ratings for
     the Portfolios.  The Portfolios 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:
     -------------------------------------------------------------------------

     Issues 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:

                                        - 38 -
<PAGE>






        
     ^ o      Leading market positions in well established industries.

     ^ o      High rates of return on funds employed.

     ^ o      Conservative capitalization structures with moderate reliance on
              debt and ample asset protection.

     ^ o      Broad margins in earnings coverage of fixed financial charges
              with high internal cash generation.

     ^ o      Well-established access to a range of financial markets and
              assured sources of alternate liquidity.
         
     Issues 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  --Issues assigned this highest rating are regarded as having the
     greatest  capacity for timely payment.  Issues in this category are
     delineated with the numbers 1 and  2 to indicate the relative degree of
     safety.

     A-1--This designation indicates that the degree of safety regarding timely
     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 designated A-1.

     Description of Moody's Investors Service, Inc.'s Corporate Bond Ratings:
     -----------------------------------------------------------------------

     Aaa- Bonds which are rated Aaa are judged to be of the best quality.  They
     carry the smallest degree of investment risk and are generally referred to
     as "gilt edge."  Interest payments are protected by a large or by an
     exceptionally stable margin and principal is secure.  While the various
     protective elements are likely to change, such changes as can be
     visualized are most unlikely to impair the fundamentally strong position
     of such issuers.

     Aa--Bonds which are rated Aa are judged to be of high quality by all
     standards.  Together with the Aaa group they comprise what are generally

                                        - 39 -
<PAGE>






     known as high grade bonds.  They are rated lower than the best bonds
     because margins of protection may not be as large as in Aaa securities or
     fluctuation of protective elements may be of greater amplitude or there
     may be other elements present which make the long term risks appear
     somewhat larger than in Aaa securities.

     Description of Standard & Poor's Corporation's Corporate Bond Ratings:
     ---------------------------------------------------------------------

     AAA--Debt rated AAA has the highest rating assigned by Standard & Poor's
     to a debt obligation.  Capacity to pay interest and repay principal is
     extremely strong.

     AA--Debt rated AA has a very strong capacity to pay interest and repay
     principal and differs from the highest rated debt issues only in small
     degree.

                            SUMMARY OF PORTFOLIO EXPENSES

              The purpose of the table below is to assist investors in
     understanding the various costs and expenses that an investor in the
     Portfolio would bear directly or indirectly. This standard format was
     developed for use by all mutual funds to help investors make their
     investment decisions. This expense information should be considered along
     with other important information, such as the Portfolio's investment
     objective and past performance. There are no transaction expenses
     associated with purchases or sales of the Portfolio's shares.
        
     ^ A.     Annual Operating Expenses 
              (as a percentage of average net assets)

              Total Operating Expenses  ^__%
         
     B.       Example: You would pay the following expenses on a $1,000
              investment, assuming (1) a 5% annual return and (2) redemption at
              the end of each time period:

              EXPLANATION OF TABLE
        
     A.       ANNUAL OPERATING EXPENSES. Annual operating expenses are based on
     the Portfolio's expenses for the last fiscal year. Management ^ fees are
     paid by the Portfolio to Fidelity Management & Research Company (FMR) for
     managing its investments and business affairs. FMR is responsible for the
     payment of all of the expenses of the Portfolio with the exception of
     certain limited expenses. Management fees and other expenses already have
     been reflected in the Portfolio's share price and dividends and are not
     charged directly to individual shareholder accounts. Please refer to the
     section "Management Contract, Distribution and Service Plan" on page 17
     for further information.
         
        
     B.       EXAMPLE OF EXPENSES. The hypothetical example illustrates the
     expenses associated with a $1,000 investment over periods of 1, 3, 5 and
     10 years, based on the expenses in the table and an  assumed annual rate
     of return of 5%.  ^ THE RETURN OF 5% AND EXPENSES SHOULD NOT BE CONSIDERED
     INDICATIONS OF ACTUAL OR EXPECTED PORTFOLIO PERFORMANCE OR EXPENSES, BOTH
     OF WHICH MAY  VARY.

     INVESTMENT OBJECTIVE AND POLICIES

              Retirement Money Market Portfolio's investment objective is 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. FMR will buy obligations for the Portfolio consistent with
     its investment objective, and which meet the quality and maturity
     standards established for the Portfolio. The Portfolio's investment
     objective is fundamental and may not be changed without the affirmative
     vote of a majority of the outstanding shares of the Portfolio. No
     assurance can be made that the Portfolio will achieve its objective, but
     it will follow the investment style described in the following paragraphs.

              The Portfolio invests in high quality, U.S. dollar- denominated
     money market instruments of U.S. and foreign issuers which present minimal
     credit risk, including:

     o        Obligations of governments and their agencies or
     instrumentalities.

     o        Obligations of the financial services industry, including banks,
              savings and loan institutions, insurance companies and mortgage
              bankers. These obligations include certificates of deposit,
              bankers' acceptances and time deposits.

     o        Short-term corporate obligations, including commercial paper,
              notes and bonds.

     o        Other short-term money market obligations.
        
              The Portfolio may engage in repurchase agreements with respect to
     such obligations. The Portfolio also may invest in restricted securities
     and may engage in reverse repurchase agreements and in short sales against
     the box. Please refer to the Appendix for ^ more information on the
     Portfolio's investments.  
         
        
              QUALITY. Pursuant to procedures adopted by the Board of Trustees,
     the Portfolio may purchase only high quality securities that FMR believes
     present minimal credit risks. To be considered high quality, a security
     must be a U.S. government security; rated in accordance with applicable
     rules in one of the two highest rating categories for short-term
     securities by at least two nationally recognized statistical rating
     services  (NRSROs) (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 have received the highest
     rating (e.g., Standard & Poor's A-1 rating) from at least two rating
     services (or one, if only one has rated the security).  ^ SECOND TIER
     SECURITIES have received ratings within the two highest categories (e.g.,

                                          5                           prospectus
<PAGE>






     Standard & Poor's A-1 or A-2) from at least two rating services (or one,
     if only one has rated the security), but do not qualify as first tier
     securities. If a security has been assigned different ratings by different
     rating services, at least two rating services must have assigned the
     higher rating in order for FMR to determine eligibility on the basis of
     that higher rating. Based on procedures adopted by the Board of Trustees,
     FMR may determine that an unrated security is of equivalent quality to a
     rated first or second tier security.
         
        
              MATURITY.  The Portfolio must limit its investments to securities
     with remaining effective maturities of 397 days or less and must maintain
     a dollar-weighted average maturity of 90 days or less.
     
    
   
     
    
   
              DIVERSIFICATION. The Portfolio may not invest more than 5% of its
     total assets in second tier securities. In addition, the Portfolio 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 Portfolio may invest in obligations of U.S. banks, foreign branches of
     U.S. banks (Eurodollars), U.S. branches and agencies of foreign banks
     (Yankee dollars), and foreign branches of foreign banks. Euro and Yankee
     dollar investments involve risks that are different from investments in
     securities of U.S. banks. 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. Additionally, there may be less public information available
     about foreign banks and their branches. Foreign branches of foreign banks
     are not regulated by U.S. banking authorities, and generally are not bound
     by accounting, auditing and financial reporting standards comparable to
     U.S. banks. Although FMR carefully considers these factors when making
     investments, the Portfolio does not limit the amount of its assets which
     can be invested in any one type of instrument or in any one foreign
     country.
         
        
              INVESTMENT LIMITATIONS.  The following summarizes the Portfolio's
     principal investment limitations. A complete listing is contained in the ^
     SAI.  
         
        
              1. ^(a) With respect to 75% of its total assets, the Portfolio
     may not invest more than 5% of its total assets in the securities of a
     single issuer (other than U.S. government securities) ^. (b) Under certain
     conditions, however, the Portfolio may invest ^ up to 25% of its total
     assets in the first tier securities of a single issuer for up to three
     days^; 
         
        


                                          6                           prospectus
<PAGE>






              2. The Portfolio ^ may not purchase the securities of any issuer
     (other than U.S. government securities) if, as a result, more than 25% of
     its total assets would be invested in the  securities of issuers whose
     principal business activities are in the same industry, except that the
     Portfolio intends to invest more than 25% of its total assets in
     obligations of institutions in the financial services industry. 
         
        
              3. The Portfolio (a) may borrow money for temporary or emergency
     purposes ^ and (b) engage in reverse repurchase agreements ^ for any
     purpose, provided that (a) and (b) in combination do not exceed 33 1/3% of
     its total assets, ^(c) may borrow money from banks, from other funds
     advised by FMR or an affiliate or by engaging in reverse repurchase
     agreements and ^ (d) may not purchase securities when borrowings (other
     than reverse repurchase agreements) exceed 5% of its total assets.
         
        
              4. The Portfolio (a) may make loans to other parties, but not in
     excess of 33 1/3% of its total assets, (b) may engage in repurchase
     agreements, and (c) may lend money (up to 10% of its net assets) to other
     funds or portfolios for which FMR or an affiliate serves as adviser.
         
        
              Except for the Portfolio's investment objective, ^  investment
     limitations 2, 3(a), 3(b), and 4(a), the investment policies described in
     this Prospectus are not fundamental and may be changed without shareholder
     approval. Except for the percentage limitation in 3(a) these investment
     limitations and policies are considered at the time of purchase; the sale
     of securities is not required in the event of a subsequent change in
     circumstances.
         
     Because the Portfolio concentrates more than 25% of its total assets in
     the financial services industry, its performance may be affected by
     conditions affecting banks and other financial services companies.
     Companies in the financial services industry are subject to various risks
     related to that industry, such as governmental regulations, changes in
     interest rates, and exposure on loans, including loans to foreign
     borrowers. Investments in the financial services industry may include
     obligations of foreign and domestic banks, savings and loan associations,
     consumer and industrial finance companies, securities brokerage companies,
     leasing companies, and a variety of firms in the insurance field.^ 

              SUITABILITY

              The Portfolio's ability to achieve its investment objective
     depends on the quality and maturity of its investments. Although the
     Portfolio's policies are designed to help maintain a stable $1.00 share
     price, all money market instruments can change in value when interest
     rates or issuers' creditworthiness change, or if an issuer or guarantor of
     a security fails to pay interest or principal when due. If these changes
     in value were large enough, the Portfolio's share price could fall below


                                          7                           prospectus
<PAGE>






     $1.00. In general, securities with longer maturities are more vulnerable
     to price changes, although they may provide higher yields.

              If you seek income at current money market rates while remaining
     conveniently liquid, the Portfolio may be appropriate for you. It has the
     flexibility to invest in corporate and bank instruments. The Portfolio
     generally is designed for investors in tax-saving retirement plans such as
     Defined Contribution Plans, 403(b) Custodial Accounts, Defined Benefit
     Plans and 457 Plans. Minimum investments for these plans may differ from
     those listed on page .

     By itself, the Portfolio does not constitute a balanced investment plan;
     its objective stresses income with preservation of capital and liquidity,
     and not the higher yields or capital appreciation that may be available
     from more aggressive investments.


     HOW TO INVEST, EXCHANGE AND REDEEM

              Shares of the Portfolio are offered continuously and may be
     purchased at the next determined net asset value per share (NAV), after an
     order is received and accepted. The Portfolio's shares are sold without a
     sales charge. The NAV of the Portfolio is determined by adding the value
     of all securities and other assets of the Portfolio, deducting its actual
     and accrued liabilities, and dividing by the number of shares outstanding.
     The Portfolio values its securities on the basis of amortized cost.
     Fidelity Service Co. (Service), calculates the NAV at the close of the
     Portfolio's business day, which coincides with the close of business of
     the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern Time (4
     p.m.). (See the holiday schedule on page .) You begin to earn dividends as
     of the first business day following the day of your purchase.

              MINIMUM INVESTMENT AND ACCOUNT BALANCE. The minimum initial
     investment to establish a new account in the Portfolio is $100,000.
     Subsequent investments may be in any amount. If you want to keep your
     account open, please leave $100,000 in it. If your account balance falls
     below $100,000 due to redemption, your account may be closed and the
     proceeds mailed to you at the record address. You will be given 30 days'
     notice that your account will be closed unless you make an additional
     investment to increase your account balance to the $100,000 minimum. The
     minimum investment requirements may differ or may not apply to
     participants of tax-saving retirement plans. 
        
              If you are purchasing shares of the Portfolio through a program
     of services offered by a securities dealer, financial or other
     institution, you should read the program materials in conjunction with
     this Prospectus. Certain features of the Portfolio ^ may be modified in
     these programs and administrative charges may be imposed for the services
     rendered.

              If you invest in this Portfolio through an employer- sponsored
     retirement plan, some of the instructions, shareholder services and phone
     numbers that follow will not apply. Speak to  ^ your institutional
     representative for additional information.
         
              HOW TO INVEST. An initial investment in the Portfolio must be
     preceded or accompanied by a completed, signed application.^ Additional
     paperwork may be required from corporations, associations and certain
     fiduciaries.

              TO INVEST BY MAIL. You must send a check payable to Fidelity
     Money Market Trust: Retirement Money Market Portfolio, together with a
     completed application, to:

              Fidelity Money Market Trust:
              Retirement Money Market Portfolio
              c/o Fidelity Institutional Retirement Services Company
              P.O. Box 650488
              Dallas, TX 75265-0488
        
              All of your purchases must be made in U.S. dollars, and checks
     must be drawn on U.S. banks. No cash will be accepted. If you make a
     purchase with more than one check, each check must have a value of at
     least $50, and the minimum investment requirement still applies. The
     Portfolio reserves the right to limit the number of checks processed at
     one time. If your check does not clear, your purchase will be ^ canceled
     and you could be held liable for any losses and/or fees incurred.
          
              TO INVEST BY WIRE. You may purchase shares of the Portfolio by
     wire. The Portfolio requires notification of all wire purchases. Prior to
     making an initial investment, investors must call the institution through
     which they trade or:

     o        RETIREMENT PLAN ACCOUNTS: call Retirement Trading at 1-
              800-962-1375 for wire information and instructions, by the close
              of the Portfolio's business day (4 p.m.) to advise them of the
              wire and to place the trade.

     o        FINANCIAL AND OTHER INSTITUTIONS: call Client Services at
              1-800-843-3001 for wire information and instructions by the close
              of the Portfolio's business day (4 p.m.) to advise them of the
              wire and to place the trade.
        
              In addition to the Portfolio's holiday schedule (see page ^ 15),
     shares cannot be purchased by wire on Dr. Martin Luther King, Jr. Day
     (observed), Columbus Day (observed), Veterans' Day (observed) or during
     any unscheduled closings of the Federal Reserve Wire System. 
         
              Investments made by wire receive the NAV next determined as of
     the day the order is received if federal funds, or monies immediately
     convertible to federal funds, are received by the following business day
     prior to the close of the NYSE (normally 4 p.m.). Investors are entitled

                                          9                           prospectus

     to the income dividend declared on the day the investor's federal funds
     are accepted by the Portfolio's custodian wire bank. It is recommended
     that investors wire funds early in the day to ensure proper credit.

              HOW TO EXCHANGE. An exchange is a convenient way to buy shares of
     the Portfolio or other Fidelity funds. The Fidelity family of funds has a
     variety of investment objectives. You may exchange shares of this
     Portfolio for shares of other Fidelity funds (subject to the minimum
     initial investment requirement) that are registered in your state. When
     making an exchange, the name, address and tax identification numbers of
     the two accounts must be identical. Investors must consult the prospectus
     of the fund to be acquired to determine eligibility and suitability. To
     protect the Portfolio's performance and shareholders, Fidelity discourages
     frequent trading in response to short-term market fluctuations. In
     particular, exchanges that coincide with "market timing" strategies can
     have adverse effects on the funds.
        
              You may exchange all or any part of the value of your accounts on
     any business day. There is currently no limit on exchanges out of the
     Portfolio^; however, exchange limits may apply to other funds. Exchanges
     may be requested in writing or by telephone and are effected at the NAV
     next determined after receipt of the exchange request. 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 already have paid in
     connection with the shares you are exchanging. This may not apply if you
     are investing through a tax-saving retirement plan.
         
              Each exchange actually represents the sale of shares of one fund
     and the purchase of shares in another, which may produce a gain or loss
     for tax purposes. A confirmation of each exchange transaction will be sent
     to you. In order to allow FMR to manage the Portfolio most effectively,
     you are strongly urged to initiate exchanges of shares as early in the day
     as possible.

              TO EXCHANGE BY TELEPHONE. Exchanges may be requested by calling:

                      Retirement Plan Accounts    800-962-1375
                      Financial and Other Institutions   800-843-3001
        
              TO EXCHANGE BY MAIL. Written requests for exchanges should
     contain the Portfolio name, account number and number of shares to be
     redeemed, and the ^ name of the fund whose shares ^ are being purchased.
     The request must be signed by a person authorized to act on behalf of the
     account. Letters should be sent to:

              The Portfolio reserves the right at any time without prior notice
     to refuse exchange purchases by any person or group if, in FMR's judgment,
     the Portfolio would be unable to invest effectively in accordance with its
     investment objective and policies or would otherwise potentially be
     adversely affected. The Portfolio may terminate or modify the exchange
     privilege in the future.

              HOW TO REDEEM. You may redeem all or a portion of your shares on
     any business day. Your shares will be redeemed at the next determined NAV
     calculated after the Portfolio has received and accepted your redemption
     request. When you redeem shares, the Portfolio normally will send you the
     proceeds on the next business day. Shares will earn dividends through the
     date of redemption; however, shares redeemed on a Friday or prior to a
     holiday will continue to earn dividends until the next business day. The
     Portfolio may hold payment on redemptions until it is reasonably satisfied
     that investments made by check have been collected (which could take up to
     seven days).
        
              TO REDEEM BY WIRE. The wiring of redemption proceeds is available
     only to investors who have previously established a wire account. In
     addition to the Portfolio's holiday schedule (see page ^_), shares cannot
     be redeemed by wire on Dr. Martin Luther King, Jr. Day (observed),
     Columbus Day (observed), Veterans' Day (observed) or during any
     unscheduled closings of the Federal Reserve Wire System. Shares redeemed
     will not receive the dividend declared on the day of redemption.
         
              TO REDEEM BY MAIL. Send a letter of instruction with your
     signature(s) guaranteed to the address given above. The letter should
     specify the name of the Portfolio, the number of shares to be redeemed,
     your name, your account number, and should include the additional
     requirements listed below that apply to your particular account.

     (e.g., Executors, Administrators, Conservators, Guardians) please call
     Client Administration for further instructions.

              A signature guarantee is a widely accepted way to protect you and
     Fidelity Investments Institutional Operations Company (FIIOC) by verifying

     registered securities associations, clearing agencies and savings
     associations.

              TO REDEEM BY TELEPHONE. You may redeem shares of the Portfolio by
     instructing FIIOC to have the proceeds of redemptions wired directly to
     your designated bank account(s). To redeem by telephone call FIIOC before
     4 p.m.:

              Provided that your account registration has not changed within
     the last 60 days, you may redeem shares of the Portfolio worth $25,000 or
     less by calling Institutional Trading. Redemption proceeds will be sent to
     the record address.

              If making immediate payment could adversely affect the Portfolio,
     it may take up to seven (7) days to pay you. Also, 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 Portfolio may suspend
     redemption or postpone payment dates. If you are unable to execute your
     transaction by telephone (for example, during times of unusual market
     activity) consider placing your order by mail.

              In order to allow FMR to manage the Portfolio most effectively,
     investors are strongly urged to initiate redemptions of shares as early in
     the day as possible and to notify the Portfolio at least one day in
     advance of large redemptions. 

              ADDITIONAL INFORMATION. You may initiate many transactions by
     telephone. Note that Fidelity will not be responsible for losses resulting
     from unauthorized transactions if it follows 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 your confirmation statements
     immediately after you receive them. If you do not want the ability to
     redeem or exchange by telephone, call Fidelity for instructions.
        
              The Portfolio reserves the right to suspend the offering of
     shares for a period of time. The Portfolio also reserves the right to
     reject any specific purchase order, including certain purchases by
     exchange (see "^ How to Exchange" ^ on page ^ 10). Purchase orders may be
     refused if, in FMR's opinion, they are of a size that would disrupt
     management of the Portfolio.
         
              SHAREHOLDER SERVICES
        
              TAX-SAVING RETIREMENT PLANS. Fidelity can set up your new account
     in the Portfolio under one of several tax-sheltered plans. These plans let
     you save for retirement and shelter your investment income from current
     taxes. Minimums may differ from those listed on page 9 and the
     corresponding information may not apply. Retirement plan participants
     should refer to their retirement plan's guidelines for further
     information.

     CHOOSING A DISTRIBUTION OPTION

              When you fill out the application for your account, you can
     choose from two distribution options:

              A.      The SHARE OPTION reinvests your distributions in
     additional shares. You are assigned this option automatically if you make
     no choice on your application.
        
              B.      The INCOME-EARNED OPTION distributes all dividends in
     cash to you.
     Participants in the above mentioned tax-saving retirement plans can elect
     to take their distributions in kind and establish an IRA rollover account
     ^ in the Portfolio.
         
              SUBACCOUNTING AND SPECIAL SERVICES. Special processing has been
     arranged with FIIOC for banks, corporations and other institutions that
     wish to open multiple accounts (a master account and subaccounts). An
     investor wishing to utilize FIIOC's subaccounting facilities or other
     special services for individual or multiple accounts may be required to
     enter into a separate agreement with FIIOC. Charges for these services, if
     any, will be determined on the basis of the level of services to be
     rendered. Subaccounts may be opened with the initial investment or at a
     later date and may be established by an investor with registration either
     by name or by number.

              The Portfolio pays for shareholder services, but not for special
     services, such as a request for a historical transcript of an account. You
     may be required to pay a fee for these special services.
        
              STATEMENTS AND REPORTS. The Portfolio will send a statement of
     your account after every transaction that affects your share balance or
     your account registration. The Portfolio does not issue share
     certificates. Dividend statements are mailed quarterly. At least twice a
     year you will receive financial statements of the Portfolio. To reduce
     expenses, only one copy of most fund reports (such as the Portfolio's ^
     Annual Report) will be mailed to your household. Write to the Portfolio if
     you need to have additional reports sent each time.

              HOLIDAY SCHEDULE. The Portfolio is open for business and its NAV
     is calculated ^ each day the NYSE is open for trading. The NYSE has
     designated the following holiday closings for ^  1994: Presidents' Day,
     Good Friday, Memorial Day^, Independence Day^, Labor Day, Thanksgiving
     Day, and Christmas Day (observed). Although FMR expects the same holiday
     schedule, with the addition of New Year's Day, to be observed in the
     future, the NYSE may modify its holiday schedule at any time. On any day ^ 

                                          14                          prospectus

     that the NYSE closes early, or as permitted by the SEC, or on any day that
     the principal government securities markets close early, such as on days
     in advance of holidays generally observed by participants in such markets,
     the right is reserved to advance the time on that day by which purchase
     and redemption requests must be received. To the extent that the ^
     portfolio securities are traded in other markets on ^ days that the NYSE
     is closed, the Portfolio's NAV may be affected on days when investors do
     not have access to the Portfolio to purchase or redeem shares. Certain ^
     Fidelity funds may follow different holiday ^ schedules.
         

     DISTRIBUTIONS AND TAXES

     The Portfolio ordinarily declares dividends from net investment income
     daily and pays such dividends monthly. The Portfolio intends to distribute
     substantially all of its net investment income and capital gains, if any,
     to shareholders within each calendar year as well as on a fiscal year
     basis.
        
              FEDERAL TAXES. Dividends derived from net investment income and
     short-term capital gains are taxable as ordinary income. The Portfolio's
     distributions are taxable when they are paid, whether you take them in
     cash or reinvest them in additional shares, except that distributions
     declared in December and paid in January are taxable as if paid on
     December ^ 31. The Portfolio will send you an ^ Internal Revenue Service
     (IRS) Form 1099-DIV by January ^ 31 showing your taxable distributions for
     the past calendar year.
         

        
              OTHER TAX INFORMATION. The information above is only a summary of
     some of the federal tax consequences generally affecting the Portfolio and
     its shareholders, and no attempt has been made to discuss individual tax
     consequences. In addition to federal tax, ^ shareholders may be subject to
     state or local taxes on ^ their investments. Investors should consult
     their tax advisors to determine whether the Portfolio is suitable to their
     particular tax situation.
         
        
              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 Portfolio to withhold 31% of distributions from your account. 
     ^ Your tax situation may be different if you are investing through a tax-
     saving retirement plan. Contact your tax adviser or plan administrator for
     further information.
         
     PORTFOLIO TRANSACTIONS

              Money market obligations generally are traded in the over-
     the-counter market through broker-dealers. A broker-dealer is a securities

                                          15                          prospectus
<PAGE>






     firm or bank which makes a market for securities by offering to buy at one
     price and sell at a slightly higher price. The difference between the
     prices is known as a spread. Since FMR trades, directly or through
     affiliated sub-advisers, a large number of securities, including those of
     Fidelity's other funds, broker-dealers are willing to work with the
     Portfolio on a more favorable spread than would be possible for most
     individual investors. 

              The Portfolio has authorized FMR to allocate transactions to some
     broker-dealers who help distribute the shares of the Portfolio or shares
     of Fidelity's other funds to the extent permitted by law, and on an agency
     basis to an affiliate, Fidelity Brokerage Services, Inc. (FBSI). FMR will
     allocate such transactions if commissions are comparable to those charged
     by non-affiliated qualified broker-dealers for similar services.

              Higher commissions may be paid to those firms that provide
     research services to the extent permitted by law. FMR also is authorized
     to allocate brokerage transactions to FBSI in order to secure from FBSI
     research services produced by third party, independent entities. FMR may
     use this research information in managing the Portfolio's assets, as well
     as assets of other clients.


     PERFORMANCE

              The Portfolio advertises its YIELD and EFFECTIVE YIELD in
     advertisements or in reports or other communications to shareholders. Both
     yield figures are based on historical earnings and are not intended to
     indicate future performance. 
        
              The Portfolio's yield refers to the income generated by an
     investment in the Portfolio over a seven-day period expressed as an annual
     percentage rate. The Portfolio also may calculate an  EFFECTIVE YIELD by
     compounding the base period return over a one- year period. The effective
     yield, although calculated similarly, will be slightly higher than the
     yield because it assumes that income earned from the investment is
     reinvested (i.e. the compounding effect of reinvestment). For the
     seven-day period ended August 31, ^ 1994, the Portfolio's yield was ^
     x.xx% and its effective yield was ^ x.xx%.
         
              The Portfolio's TOTAL RETURN is based on the overall dollar or
     percentage change in value of a hypothetical investment in the Portfolio
     and assumes all distributions are reinvested. 

              A CUMULATIVE TOTAL RETURN reflects the Portfolio's performance
     over a stated period of time. 

              An AVERAGE ANNUAL TOTAL RETURN reflects the hypothetical annually
     compounded rate that would have produced the same cumulative total return
     if the Portfolio's performance had been constant over the entire period.
     Because average annual returns tend to smooth out variations in the


                                          16                          prospectus

     Portfolio's return, investors should recognize that they are not the same
     as actual year-by-year results.


     MANAGEMENT CONTRACT, DISTRIBUTION AND SERVICE PLAN
        
              MANAGEMENT CONTRACT. For managing its investments and business
     affairs, the Portfolio pays a monthly management fee to FMR at the annual
     rate of .42% of the average net assets of the Portfolio throughout the
     month. FMR pays all expenses of the Portfolio with the following
     exceptions: the payment of fees and expenses of all Trustees of the Trust
     who are not "interested persons" of the Trust or FMR; brokerage fees or
     commissions (if any); interest on borrowings; taxes; and such
     extraordinary non- recurring expenses as may arise, including litigation
     to which the Portfolio may be a party. The management fee will be reduced
     by the ^ fees and expenses of those Trustees who are not " interested
     persons" of the Trust paid by the Portfolio. For the fiscal year ended
     August 31, ^ 1994, the Portfolio paid FMR ^  $x,xxx,xxx in management fees
     before reduction for ^ the fees and expenses of the non-interested members
     of the Board of Trustees.
         
              FMR has entered into a sub-advisory agreement with FMR Texas Inc.
     (FMR Texas), under which FMR Texas has primary responsibility for
     providing portfolio investment management services, while FMR retains
     responsibility for providing other management services. Under the terms of
     the agreement, FMR pays FMR Texas fees equal to 50% of the management fees
     payable to FMR under its current management contract with the Portfolio.
     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.
        
              FIIOC performs transfer agency, dividend disbursing and
     shareholder servicing functions for the Portfolio. Service calculates the
     Portfolio's NAV and dividends, and maintains the Portfolio's general
     accounting records. The costs of providing these services are borne by FMR
     pursuant to its ^ management contract with the Portfolio. Both FIIOC and
     Service are affiliates of FMR.
         
              FMR may, from time to time, agree to reimburse the Portfolio for
     expenses above a specific percentage of average net assets. FMR retains
     the ability to be repaid by the Portfolio for these expense reimbursements
     in the amount that expenses fall below the limit prior to the end of the
     fiscal year. Fee reimbursements by FMR will increase the Portfolio's
     yield, and subsequent repayment by the Portfolio will lower its yield.
        
              DISTRIBUTION AND SERVICE PLAN. The ^ Board of Trustees, on behalf
     of the ^ Portfolio, has adopted a Distribution and Service Plan (the Plan)
     under Rule 12b-1 (the Rule) of the Investment Company Act of 1940 (1940
     Act). The Rule provides in substance that a mutual fund may not engage
     directly or indirectly in financing any activity that is intended
     primarily to result in the sale of shares of the fund except pursuant to a
     plan adopted by the fund under the Rule. No separate payments are
     authorized to be made by the Portfolio under the Plan. Rather, the Plan

                                          17                          prospectus

     recognizes that FMR may use its management fee or other resources to pay
     expenses associated with activities primarily intended to result in the
     sale of the Portfolio's shares.

              THE TRUST AND THE FIDELITY ORGANIZATION. The Portfolio is a
     diversified portfolio of Fidelity Money Market Trust, an open- end,
     management investment company organized as a ^ Delaware business trust by
     a Trust Instrument dated June 20, 1991. The Board of Trustees of the Trust
     supervises Trust activities and reviews contractual arrangements with
     companies that provide the Portfolio with services. The Trust is not
     required to hold annual shareholder meetings, although special meetings
     may be called for a specific Portfolio or the Trust as a whole for
     purposes such as electing or removing Trustees, changing fundamental
     investment policies or approving a new or amended management contract. As
     a shareholder, ^ the number of votes you are entitled to is based upon the
     dollar value of your investment.
         
              Fidelity Investments is one of America's largest investment
     management organizations and has its principal business address at 82
     Devonshire Street, Boston, MA. It is composed of a number of different
     subsidiaries and divisions which provide a variety of financial services
     and products. The Trust employs various Fidelity companies to perform
     certain activities required for its operation.
        
              FMR is the original Fidelity company, founded in 1946. It
     provides a number of mutual funds and other clients with investment
     research and portfolio management services. FMR maintains a large staff of
     experienced investment personnel and a full complement of related support
     facilities. As of August 31, ^ 1994, FMR advised funds having more than ^
     xx million shareholder accounts with a total value of more than ^ $xxx
     billion. Fidelity Distributors Corporation (Distributors) distributes
     shares for the Fidelity funds.
         
        
              FMR Corp. is the ultimate parent company ^ of FMR and FMR Texas. 
     Through ownership of voting common stock, members of the Edward C. Johnson
     3d ^ family form a controlling group with respect to FMR Corp.  Changes
     may occur in the Johnson family group, through death or disability, which
     would result in changes in each individual family members' holding of
     stock.  Such changes could result in one or more family members becoming
     holders of over 25% of the stock.  FMR Corp. has received an opinion of
     counsel that changes in the composition of the Johnson family group under
     these circumstances would not result in the termination of the Portfolios'
     management or distribution contracts and, accordingly, would nor require a
     shareholder vote to continue operation under those contracts.

              The following paragraphs provide a brief description of
     securities in which the Portfolio may invest and transactions it may make.
     The Portfolio is not limited by this discussion, however, and may purchase
     other types of securities and enter into other types of transactions if
     they are consistent with the Portfolio's investment objectives and
     policies.
        
              A complete listing of the Portfolio's policies and limitations
     and more detailed information about the Portfolio's investments are
     contained in the Portfolio's SAI.  Current holdings and recent investment
     strategies are described in the Portfolio's financial report, which is
     sent to shareholders twice a year.
         
        
              ASSET-BACKED SECURITIES may include interests in pools of
     mortgages, loans, ^ receivables or other assets. Payment of principle and
     interest may be largely dependent upon the cash flows generated by the
     assets backing the securities.
         
        
              BANKERS' ACCEPTANCES ^ are negotiable obligations of a bank to
     pay a draft which has been drawn on it by a customer. These obligations
     are drawn on large banks and usually backed by goods in international
     trade.
         
        
              CERTIFICATES OF DEPOSIT ^ are negotiable certificates
     representing a commercial bank's obligations to repay funds deposited with
     it, earning special rates of interest over a given period of time.
         
        
              COMMERCIAL PAPER ^ are short-term obligations issued by banks,
     broker-dealers, corporations and other entities for purposes such as
     financing their current operations.
         
        
              CORPORATE OBLIGATIONS ^ are bonds and notes issued by
     corporations and other business organizations in order to finance their
     long-term credit needs.
         
              DELAYED DELIVERY TRANSACTIONS. The Portfolio may buy and sell
     securities on a when-issued or delayed delivery basis, with payment and
     delivery taking place at a future date. The market value of securities
     purchased in this way may change before the delivery date, which could
     affect the market value of the Portfolio's assets. Ordinarily, the
     Portfolio will not earn interest on securities purchased until they are
     delivered.
        
              ILLIQUID INVESTMENTS.^  Under the supervision of the Board of
     Trustees, FMR determines the liquidity of the Portfolio's investments. The
     absence of a trading market can make it difficult to ascertain a market
     value for illiquid investments.  ^ Disposing of illiquid investments may

                                          19                          prospectus
<PAGE>






     involve time-consuming negotiation and legal expenses, and it may be
     difficult or impossible for the Portfolio to sell ^ them promptly at ^ any
     acceptable price. 
         
              INTERFUND BORROWING PROGRAM. The Portfolio has received
     permission from the SEC to lend money to and borrow money from other funds
     advised by FMR or its affiliates. Interfund loans and borrowings normally
     will extend overnight, but can have a maximum duration of seven days. The
     Portfolio will lend through the program only when the returns are higher
     than those available at the same time 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. The
     Portfolio will not lend more than 10% of its assets to other funds, and
     will not borrow through the program if, after doing so, total outstanding
     borrowings would exceed 15% of total assets. Loans may be called on one
     day's notice, and the Portfolio 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. 

              MUNICIPAL OBLIGATIONS are issued to raise money for various
     public purposes, including general purpose financing for state and local
     governments as well as financing for specific projects or public
     facilities. Municipal obligations may be backed by the full taxing power
     of a municipality or by the revenues from a specific project or the credit
     of a private organization.
        
              REPURCHASE AGREEMENTS. In a repurchase agreement, the Portfolio
     buys a security at one price and simultaneously agrees to sell it back at
     a higher price. In the event of the bankruptcy of the other party to a
     repurchase agreement the Portfolio could experience delays in recovering
     its cash. To the extent that, in the meantime, the value of the securities
     purchased had decreased, the Portfolio could experience a loss. In all
     cases, FMR must find the creditworthiness of the other party to ^ the
     transaction satisfactory. 
         
              REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement,
     the Portfolio temporarily transfers possession of a portfolio instrument
     to another party, such as a bank or broker- dealer, in return for cash. At
     the same time, the Portfolio agrees to repurchase the instrument at an
     agreed upon price and date. The Portfolio expects that it will engage in
     reverse repurchase agreements for temporary purposes such as funding
     redemptions or when it is able to invest the cash so acquired at a rate
     higher than the cost of the agreement, which would increase the income
     earned by the Portfolio. Reverse repurchase agreements may increase the
     risk of fluctuation in the market value of the Portfolio's assets or its
     yield.
        
              RESTRICTED SECURITIES^ cannot be sold to the public without
     registration under the Securities Act of 1933^. Unless registered for
     sale, these securities can only be sold in privately negotiated
     transactions or pursuant to an exemption from registration.

                                          20                          prospectus
<PAGE>






         
        
              TIME DEPOSITS ^ are non-negotiable deposits in a banking
     institution earning a specified interest rate over a given period of time.
         

              U.S. GOVERNMENT OBLIGATIONS are securities issued or guaranteed
     by the U.S. Treasury or by an agency or instrumentality of the U.S.
     government. Not all U.S. government obligations are backed by the full
     faith and credit of the United States. For example, securities issued by
     the Federal Home Loan Banks or by the Federal National Mortgage
     Association are supported by the agency'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 agency
     that issued them. There is no guarantee that the government will support
     these types of securities, and therefore they involve more risk than other
     government obligations.
        
              STRIPPED GOVERNMENT SECURITIES are created by separating the
     income and principal components of a debt instrument and selling them
     separately.  Each Portfolio may purchase U.S. Treasury STRIPS (Separate
     Trading of Registered Interest and Principal of Securities), that are
     created when the coupon payments and the principal payment are stripped
     from an outstanding Treasury bond by the Federal Reserve Bank of New York.
         
        
              VARIABLE OR FLOATING RATE OBLIGATIONS ^ provide for periodic
     adjustments of the interest rates paid.  Floating rate obligations have
     interest rates that change whenever there is a change in a designated base
     rate, while variable rate obligations provide for a specified periodic
     adjustment in the interest rate.  These formulas are designed to result in
     a market value for the instrument that approximates its par value.  When
     determining the maturity of a variable or floating rate ^  obligation, the
     ^ Portfolio may look to the date the demand feature can be exercised, or
     to the date the interest rate is readjusted, rather than to the final
     maturity of the ^  obligation.
         
              ZERO COUPON BONDS do not make regular interest payments. Instead,
     they are sold at a deep discount from their face value. In calculating its
     daily dividend, the Portfolio takes into account as income a portion of
     the difference between a zero coupon bond's purchase prices and its face
     values. Because they do not pay current income, the prices of zero coupon
     bonds can be very volatile when interest rates change.

     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 Portfolio'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 Portfolio'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 Portfolio's
     investment policies and limitations.
        
              The Portfolio's fundamental investment policies and limitations
     can not 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 Portfolio.  However, except for the fundamental
     investment limitations set forth below, the investment policies and
     limitations described in this ^ SAI are not fundamental and may be changed
     without shareholder approval.  THE FOLLOWING ARE THE PORTFOLIO'S
     FUNDAMENTAL INVESTMENT LIMITATIONS SET FORTH IN THEIR ENTIRETY.  THE
     PORTFOLIO MAY NOT:
         
              (1) with respect to 75% of the Portfolio's total assets, purchase
     the security of any issuer (other than obligations issued or guaranteed by
     the government of the United States, its agencies or instrumentalities)
     if, as a result thereof:  (a) more than 5% of the Portfolio's total assets
     would be invested in the securities of such issuer; or (b) the Portfolio
     would hold more than 10% of the voting securities of such issuer;
        
              (2) issue ^ senior securities, except as permitted under the
     Investment Company Act of 1940;
         
        
              ^(3) borrow money, except that the Portfolio 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 Portfolio'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 Portfolio may be deemed 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 by the government of the United States,

                                        - 3 -
<PAGE>






     its agencies or instrumentalities) if, as a result, more than 25% of the
     Portfolio'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 Portfolio 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 Portfolio 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 the Portfolio's 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 Portfolio 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 Portfolio^ .
         
     THE FOLLOWING LIMITATIONS ARE NOT FUNDAMENTAL AND MAY BE CHANGED WITHOUT
     SHAREHOLDER APPROVAL.

              (i)     The Portfolio 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 Portfolio 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 Portfolio 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 Portfolio will not purchase any
     security while borrowings (excluding reverse repurchase agreements)
     representing more than 5% of its total assets are outstanding.  The
     Portfolio 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 Portfolio's total assets.

              (iii)   The Portfolio 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 Portfolio does not currently intend to purchase
     securities on margin, except that the Portfolio 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 Portfolio does not currently intend to purchase any
     security if, as a result, 10% or more 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 Portfolio 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 Portfolio does not currently intend to lend assets
     other than securities to other parties, except by lending money (up to 10%
     of the Portfolio'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.)
         
        
              ^(viii)  The Portfolio does not currently intend to purchase the
     securities of any issuer (other than securities issued or guaranteed by
     domestic or foreign governments or political subdivisions thereof) if, as
     a result, more than 5% of its total assets would be invested in the
     securities of business enterprises that, including predecessors, have a
     record of less than three years of continuous operation.
         
        
              ^(ix)   The Portfolio does not currently intend to invest in oil,
     gas, or other mineral exploration or development programs or leases.
         
        


                                        - 5 -

              ^(x)    The Portfolio does not currently intend to purchase the
     securities of any issuer if those officers and Trustees of the Portfolio
     and those officers and directors of FMR who individually own more than 1/2
     of 1% of the securities of such issuer together own more than 5% of such
     issuer's securities.
         
        
              (xi)    The Portfolio does not currently intend to invest all of
     its assets in the securities of a single open-end management investment
     company with the same fundamental investment objective, policies, and
     limitations as the Portfolio.
         
        
              For the Portfolio's policies on quality and maturity, see the
     section entitled "Quality and Maturity" on page .
         
        
              AFFILIATED BANK TRANSACTIONS.  ^ The Portfolio may engage in
     transactions with ^ financial institutions that are, or may be considered
     to be, "affiliated persons" of the ^ Portfolios 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.  Asset-backed securities may include
     pools of mortgages, loans, ^ receivables or other assets. Payment of
     principle 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 financial institution(s) providing the
     credit support.
         
        
              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, of U.S. branches and agencies of foreign banks, and foreign
     branches of foreign banks.  The Portfolio also may 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 and foreign government agencies or
     instrumentalities, and U.S. and foreign financial institutions, including
     savings and loan institutions, insurance companies, mortgage bankers and

                                        - 6 -

     real estate investment trusts, as well as banks.  The Portfolio may
     purchase obligations of banks, savings and loan institutions and other
     financial institutions whose creditworthiness might not otherwise meet the
     Portfolio's standards, provided that (i) the principal amount of the
     instrument acquired by the Portfolio is insured in full by the Federal
     Deposit Insurance Corporation (FDIC) and (ii) the aggregate investment
     made in any one such bank or institution does not exceed $100,000.
         
              The obligations of foreign branches and agencies 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 upon 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, evidences of ownership of portfolio securities may be held
     outside of the U.S. and the Portfolio 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 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 also involve certain additional
     risks.  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. 

              DELAYED DELIVERY TRANSACTIONS.  The Portfolio may buy and sell
     securities on a delayed delivery or when-issued basis.  These transactions
     involve a commitment by the Portfolio to purchase or sell specific
     securities at a predetermined price and/or yield, with payment and
     delivery taking place after the customary settlement period for that type
     of security (and more than seven days in the future).  Typically, no
     interest accrues to the purchaser until the security is delivered. 

              When purchasing securities on a delayed delivery basis, the
     Portfolio assumes the rights and risks of ownership, including the risk of
     price and yield fluctuations.  Because the Portfolio is not required to
     pay for securities until the delivery date, these risks are in addition to
     the risks associated with the Portfolio's other investments.  If the
     Portfolio 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 Portfolio will set aside appropriate liquid assets in a
     segregated custodial account to cover its purchase obligations.  When the
     Portfolio has sold a security on a delayed delivery basis, the Portfolio
     does not participate in further gains or losses with respect to the

                                        - 7 -
<PAGE>






     security.  If the other party to a delayed delivery transaction fails to
     deliver or pay for the securities, the Portfolio could miss a favorable
     price or yield opportunity, or could suffer a loss.

              The Portfolio 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.  
        
              REPURCHASE AGREEMENTS.  In a repurchase agreement, the Portfolio
     purchases a security and simultaneously commits to resell that security to
     the 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.  A repurchase
     agreement involves the obligation of the seller to pay the agreed upon 
     resale price, which obligation is in effect secured by the value (at least
     equal to the amount of the agreed upon resale price and marked to market
     daily) of the underlying security.  The Portfolio may engage in a
     repurchase agreement with respect to any type of security in which it is
     authorized to invest (except that the security may have a maturity in
     excess of 397 days).  While it does not presently appear possible to
     eliminate all risks from these transactions (particularly the possibility
     of a decline in the market value of the underlying securities, as well as
     delays and costs to the Portfolio in connection with bankruptcy
     proceedings), it is the Portfolio's current policy to limit repurchase
     agreements to those parties whose creditworthiness has been reviewed and
     found satisfactory by FMR.
         
              REVERSE REPURCHASE AGREEMENTS.  In a reverse repurchase
     agreement, the Portfolio 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 Portfolio will maintain
     appropriate liquid assets in a segregated custodial account to cover its
     obligation under the agreement. The Portfolio 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 Portfolio's assets and may be viewed as a form of 
     leverage.
        
              STRIPPED GOVERNMENT SECURITIES are created by separating the
     income and principal components of a debt instrument and selling them
     separately.  The Portfolio may purchase U.S. Treasury STRIPS (Separate
     Trading of Registered Interest and Principal of Securities), that 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 Resolution Funding Corporation (REFCORP) can also be
     stripped in this fashion.  REFCORP Strips are eligible investments for the
     Portfolios.
         
        
              The Portfolio can purchase privately stripped government
     securities, which are created when a dealer deposits a Treasury security

                                        - 8 -
<PAGE>






     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 Financing Corporation (FICO)
     can also be stripped in this fashion.
         
        
              Because of the SEC's views on privately stripped government
     securities, the must evaluate them as it would non-government securities
     pursuant to regulatory guidelines applicable to all money market funds.
     Accordingly, the Portfolio 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, been judged to be of equivalent
     quality by FMR pursuant to procedures adopted by the Board of Trustees.
         
              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 Portfolio's investments and, through
     reports from FMR, the Board monitors investments in illiquid instruments. 
     In determining the liquidity of the Portfolio'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 Portfolio's rights and obligations relating to the investment). 
     Investments currently considered by the Portfolio 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 Portfolio were in a
     position where 10% or more of its net assets were invested in illiquid
     securities, it would seek to take appropriate steps to protect liquidity.

              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 Portfolio 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 the
     Portfolio may be permitted to sell a security under an effective
     registration statement.  If, during such a period, adverse market
     conditions were to develop, the Portfolio might obtain a less favorable
     price than prevailed when it decided to seek registration of the security.

                                        - 9 -

     However, in general, the Portfolio anticipates holding restricted
     securities to maturity or selling them in an exempt transaction.
        
              QUALITY AND MATURITY.  Pursuant to procedures adopted by the
     Board of Trustees, the Portfolio may purchase only high-quality securities
     that FMR believes present minimal credit risks.  To be considered high
     quality, a security must be a U.S. government security; 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 have received the highest rating
     (e.g., Standard & Poor's A-1 rating) from at least two rating services (or
     one, if only one has rated the security).  Second tier securities have
     received ratings within the two highest categories (e.g., Standard &
     Poor's A-1 or A-2) from at least two rating services (or one, if only one
     has rated the security), but do not qualify as first tier securities.  If
     a security has been assigned different ratings by different rating
     services, at least two rating services must have assigned the higher
     rating in order for FMR to determine eligibility on the basis of that
     higher rating.  Based on procedures adopted by the Board of Trustees, FMR
     may determine that an unrated security is of equivalent quality to a rated
     first or second tier security.
         
        
              The Portfolio 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.
         
              SHORT SALES AGAINST THE BOX.  The Portfolio 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 Portfolio in
     anticipation of increased interest rates without sacrificing the current
     yield of the securities sold short.  If the Portfolio 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
     Portfolio will incur transaction costs, including interest expenses, in
     connection with opening, maintaining and closing short sales against the
     box.
        
              VARIABLE OR FLOATING RATE OBLIGATIONS ^ provide for periodic
     adjustments of the interest rate paid.  Floating rate obligations have
     interest rates that change whenever there is a change in a designated base
     rate while variable rate ^  obligations provide for a specified periodic
     adjustment in the interest rate.  These formulas are designed to result in
     a market value for the ^ instrument that approximates its par value.

                                        - 10 -
<PAGE>






         
        
              ^ Some variable or floating rate ^ obligations permit holders to
     demand payment of the unpaid principal balance plus an accrued interest
     from the issuers or certain financial intermediaries.  Issuers or
     financial intermediaries who provide demand features or stand-by
     commitments often obtain letters of credit (LOCs) or other guarantees from
     domestic or foreign banks to support their repurchase commitments.  FMR
     may rely upon its evaluation of a bank's credit in determining whether to
     purchase an obligation supported by an LOC.  In evaluating a foreign
     bank's credit, FMR will consider whether adequate public information about
     the bank is available and whether the bank may be subject to unfavorable
     political or economic developments, currency controls, or other
     governmental restrictions that might affect the bank's ability to honor
     its credit commitment.
         
        
              When determining the maturity of a variable or floating rate
     obligation, the Portfolio may look to the date the demand feature can be
     exercised, or to the date the interest rate is readjusted, rather than to
     the final maturity of the obligation.
         

     PORTFOLIO TRANSACTIONS
        
              All orders for the purchase or sale of portfolio securities are
     placed on behalf of the Portfolio by FMR ^ pursuant to authority contained
     in the ^ management contract.  If FMR grants investment management
     authority to the sub-adviser (see the section entitled "Management and
     Service Contracts"), the sub-adviser will be 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 Portfolio 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 Portfolio may execute portfolio transactions with
     broker-dealers who provide research and execution services to the
     Portfolio ^ 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; the availability of securities or the purchasers or
     sellers of securities; furnishing analyses and reports concerning issuers,

                                        - 11 -
<PAGE>






     industries, securities, economic factors and trends, portfolio strategy
     and performance of accounts; and effecting securities transactions and
     performing 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 Portfolio 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 Portfolio may be useful to FMR in rendering
     investment management services to the Portfolio ^ 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 Portfolio.  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 Portfolio 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 Portfolio 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 Portfolio 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, Ltd. (FBSL),
     subsidiaries of FMR Corp., if the commissions are fair ^, reasonable, and
     comparable to commissions charged by ^  non-affiliated, qualified
     brokerage firms for similar services.

              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 Portfolio and review the commissions paid by
     the Portfolio over representative periods of time to determine if they are
     reasonable in relation to the benefits to the Portfolio.
        
              From time to time the Trustees will review whether the recapture
     for the benefit of the Portfolio of some portion of the brokerage
     commissions or similar fees paid by the Portfolio on portfolio
     transactions is legally permissible and advisable.  The Portfolio 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 Portfolio to seek such recapture.
         
        
              Although the Trustees and officers of the Trust are substantially
     the same as those of other funds managed by FMR, investment decisions for
     the ^ Trust 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 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
     the Portfolio. In some cases this system could have a detrimental effect
     on the price or value of the security as far as the Portfolio is
     concerned.  In other cases, however, the ability of the Portfolio to
     participate in volume transactions will produce better executions and
     prices for the Portfolio.  It is the current opinion of the Trustees that
     the desirability of retaining FMR as investment adviser to the Portfolio
     outweighs any disadvantages that may be said to exist from exposure to
     simultaneous transactions.
         
     VALUATION OF PORTFOLIO SECURITIES



                                        - 13 -
<PAGE>






              The Portfolio values its investments on the basis of amortized
     cost.  This technique involves valuing an instrument at its cost as
     adjusted for amortization of premium or accretion of discount rather than
     its value based on current market quotations or appropriate substitutes
     which reflect current market conditions.  The amortized cost value of an
     instrument may be higher or lower than the price the Portfolio would
     receive if it sold the instrument.

              Valuing the Portfolio's instruments on the basis of amortized
     cost and use of the term "money market fund" are permitted by Rule 2a-7
     under the 1940 Act. The Portfolio must adhere to certain conditions under
     Rule 2a-7; these conditions are summarized in the Prospectus.

              The Board of Trustees of the Trust oversees FMR's adherence to
     SEC rules concerning money market funds, and has established procedures
     designed to stabilize the Portfolio'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 Portfolio'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.

              During periods of declining interest rates, the Portfolio's yield
     based on amortized cost may be higher than the yield based on market
     valuations.  Under these circumstances, a shareholder in the Portfolio
     would be able to obtain a somewhat higher yield than would result if the
     Portfolio utilized market valuations to determine its NAV.  The converse
     would apply in a period of rising interest rates.

     PERFORMANCE

              The Portfolio'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, which 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 the funds based
     on yield. In addition to the mutual fund rankings, the Portfolio's
     performance may be compared to mutual fund performance indices prepared by
     Lipper.

              The Portfolio may also compare its performance or the performance
     of securities in which it may invest to averages published by IBC/USA
     (Publications), Inc. of Ashland, MA, 01721. These averages assume
     reinvestment of distributions. The Money Fund Averages/All Taxable which
     is reported in the Money Fund Report, covers over 607 taxable money market
     funds. The Portfolio may reference the growth and variety of money market
     mutual funds and FMR's innovation and participation in the industry.

               The Portfolio also may compare its performance to the yields or
     averages of other money market securities as reported by the Federal
     Reserve Bulletin, by TeleRate, a financial information network, or by
     Salomon Brothers Inc., a broker-dealer firm, and to other fixed-income
     investments such as Certificates of Deposit (CDs).  The principal value
     and interest rate of CDs and money market securities are fixed at the time
     of purchase, whereas the Portfolio's yield will fluctuate.  Unlike some
     CDs and certain other money market securities, money market mutual funds
     are not insured by the FDIC.  Investors should give consideration to the
     quality and maturity of the portfolio securities of the respective
     investment companies when comparing investment alternatives.

              YIELD CALCULATIONS.  The Portfolio's yield refers to the income
     generated by an investment in the Portfolio over a seven day period
     expressed as an annual percentage rate. The effective yield, although
     calculated similarly, will be slightly higher than the yield because it
     assumes that income earned from the investment is reinvested (the
     compounding effect of reinvestment).  In addition to the current yield,
     the Portfolio may quote yields in advertising based on any historical
     seven day period.

              TOTAL RETURN CALCULATIONS.  Total returns quoted in advertising
     reflect all aspects of the Portfolio's return, including the effect of
     reinvesting dividends and capital gain distributions (if any). Average
     annual returns are calculated by determining the growth or decline in
     value of a hypothetical historical investment in the  Portfolio 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 the value of the investment had been constant over the period. 
     For example, a cumulative return of 100% over ten years would produce an
     average annual return of 7.18%, which is the steady annual rate that would
     equal 100% growth on a compounded basis in ten years.  While average
     annual returns are a convenient means of comparing investment
     alternatives, investors should realize that the Portfolio's performance is
     not constant over time, but changes from year to year, and that average
     annual returns represent averaged figures as opposed to the actual
     year-to-year performance of the Portfolio. 
        
              In addition to average annual returns, the Portfolio may quote
     unaveraged or cumulative total returns reflecting the simple change in the
     value of an investment over a stated period.  Average annual and
     cumulative total returns may be quoted as percentages or as dollar amounts
     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 in order to illustrate
     the relationship of these factors and their contributions to total return. 
     Total returns, yields, and other performance information may be quoted
     numerically or in a table, graph, or similar illustration.  The
     Portfolio's cumulative total returns and average annual returns for the
     fiscal year ended August 31, ^ 1994 were as follows:

              Explanatory Notes:  With an initial investment of $10,000 made on
     ^ December 2, 1988, the net amount invested in shares of the Portfolio was
     $10,000.  The cost of the initial investment ($10,000) together with the
     aggregate cost of reinvested dividends for the period covered (that is,
     their cash value at the time they were reinvested) amounted to ^ $______. 
     If distributions had not been reinvested, the amount of distributions
     earned from the Portfolio over time would have been smaller and the cash
     payments (dividends) for the period would have come to ^ $_____.  The
     Portfolio did not distribute any capital gains during the period.
         
              The Portfolio may reference and discuss its fund number, Quotron
     number, CUSIP number, and current portfolio manager in advertising.  

              From time to time, in reports and promotional literature, the
     Portfolio's performance also may be compared to other mutual funds tracked
     by financial or business publications and periodicals.  For example, the
     Portfolio may quote Morningstar, Inc. in its advertising materials. 
     Morningstar, Inc. is a mutual fund rating service that rates mutual funds
     of the basis or risk-adjusted performance.  In addition, the Portfolio may
     quote financial or business publications and periodicals as they relate to
     portfolio management, investment philosophy, and investment techniques.

     appropriate categories over specific periods of time may also be quoted in
     advertising. 

     ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

              If the Trustees determine that existing conditions make cash
     payment 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 Portfolio'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 Portfolio 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 Portfolio 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.  

              The Portfolio 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 Portfolio would be unable
     to invest effectively in accordance with its investment objective and
     policies or might otherwise be adversely affected.

     DISTRIBUTION 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.  Dividends from the Portfolio will not normally
     qualify for the dividends-received deduction available to corporations,
     since the Portfolio's income is primarily derived from interest income and
     short-term capital gains.  Depending upon state law, a portion of the
     Portfolio's dividends attributable to interest income derived from U.S.
     government securities may be exempt from state and local taxation.  The
     Portfolio will provide information on the portion of the Portfolio's
     dividends, if any, that qualify for this exemption.

              CAPITAL GAIN DISTRIBUTIONS.  The Portfolio may distribute
     short-term capital gains once a year or more often as necessary to
     maintain its NAV at $1.00 per share or to comply with distribution


                                        - 18 -
<PAGE>






     requirements under federal tax law.  The Portfolio does not anticipate
     earning long-term capital gains on securities held by the Portfolio.

              TAX STATUS OF THE PORTFOLIO.  The Portfolio has qualified and
     intends to qualify as a "regulated investment company" under the Internal
     Revenue Code of 1986, as amended (the Code), so that the Portfolio will
     not be liable for federal income or excise taxes on net investment income
     or capital gains to the extent that these are distributed to shareholders
     in accordance with applicable provisions of the Code.

     FMR
        
              FMR is a wholly owned subsidiary of FMR Corp., ^ the ultimate

     Corp.  Through ownership of voting common stock and the execution of a
     shareholders' voting agreement, Edward C. Johnson 3d, Johnson family
     members, and various trusts for the benefit of the Johnson family 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: Fidelity Service Company (Service), which is the

     MANAGEMENT AND SERVICE CONTRACTS
        
              The Portfolio employs FMR to furnish investment advisory and
     other services.  Under its ^ management contract with the Portfolio, FMR
     acts as investment adviser and, subject to the supervision of the Board of
     Trustees, directs the investments of the Portfolio in accordance with its
     investment objective, policies and limitations.  FMR also provides the
     Portfolio with all necessary office facilities, equipment and personnel
     for servicing the Portfolio's investments and compensates all officers of
     the Trust, all Trustees who are "interested persons" of the Trust or of
     FMR, and all personnel of the Trust 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 Portfolio.  These services include providing facilities for
     maintaining the Portfolio's organization, supervising relations with
     custodians, transfer and pricing agents, accountants, underwriters and
     other persons dealing with the Portfolio; preparing all general
     shareholder communications and conducting shareholder relations;
     maintaining the Trust's records and the registration of the Portfolio's
     shares under federal and state law; developing management and shareholder
     services for the Portfolio; and furnishing reports, evaluations and
     analyses on a variety of subjects to the Trustees on behalf of the
     Portfolio.
         
        
              FMR pays all of the expenses of the Portfolio, except as
     described below.  Specific expenses payable by FMR include, without
     limitation, the fees and expenses of registering and qualifying the
     Portfolio and its shares for distribution under federal and state
     securities laws; expenses of typesetting for printing the Prospectus and ^
     SAI; custodian charges; auditing and legal expenses; insurance expenses;
     association membership dues; the expense of reports to shareholders;
     shareholders' meetings; and proxy solicitations.

              ^ FIIOC is transfer ^, dividend disbursing ^, and shareholder
     servicing agent for the Portfolio.  The costs of these services are borne
     by FMR pursuant to its ^ management contract with Portfolio.  Service
     calculates the Portfolio's NAV and dividends, and maintains the
     Portfolio's general accounting records. The costs of these services are
     also borne by FMR pursuant to its management contract with the Portfolio.
         
        
              FMR pays all other expenses of the Portfolio with the following
     exceptions:  the payment of fees and expenses of all Trustees of the Trust
     who are not "interested persons" of the Trust or FMR; interest on
     borrowings; taxes; brokerage commissions (if any); and such nonrecurring
     expenses as may arise, including costs of litigation to which the
     Portfolio may be a party, and any obligation it may have to indemnify its
     officers and Trustees with respect to ^ litigation.
         
        
              ^ For these services and FMR's payment of the Portfolio's
     expenses, the Portfolio pays a monthly management fee to FMR at the annual
     rate of .42% of the average net assets of the Portfolio throughout the
     month pursuant to a management contract approved by  shareholders on
     October 26, 1989.  The management fee paid to FMR ^ is reduced by an
     amount equal to the fees and expenses of those Trustees who are not
     "interested persons" of the Trust or FMR.  For the twelve month ^ periods
     ended August 31, 1994 and August 31, 1993, and the ten month period ended
     August 31, 1992,^ the Portfolio paid $___________, $6,976,761, and
     $5,039,309^ in management fees, respectively, before reduction for ^ fees
     and expenses of the non-interested Trustees.
         
        
              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 Portfolio. Under
     the sub-advisory agreement, FMR pays FMR Texas fees equal to 50% of the
     management fee payable to FMR under its current management contract with
     the Portfolio.  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.  For the twelve month ^ periods ended August 31, 1994 and
     August 31, 1993, and the ten month period ended August 31, 1992,^ FMR paid
     FMR Texas fees that amounted to $________, $3,482,286, and $2,515,800, ^
     respectively.
     ^
         
        
              The Portfolio has a Distribution Agreement with Distributors,^ a
     Massachusetts corporation organized on July 18, 1960^.  Distributors 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 Distributors to use all reasonable
     efforts, consistent with its other business, to secure purchasers for
     shares of the ^ Portfolios, which are continuously offered.  Promotional

     and administrative expenses in connection with the offer and sale of
     shares are paid by FMR.
     ^
         
     DISTRIBUTION AND SERVICE PLAN
        
              The Board of Trustees, on behalf of the Portfolio, has adopted a
     Distribution and Service Plan (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 the ^ fund except
     pursuant to a plan adopted by the ^ fund under the Rule.  The Trust's
     Board of Trustees ^ has adopted the Plan to allow the Portfolio and FMR to
     incur certain expenses that might be considered to constitute indirect
     payment by the Portfolio of distribution expenses.  Under the Plan, if the
     payment of management fees by the Portfolio to FMR is deemed indirect
     financing by the Portfolio ^ of the distribution of its shares, such
     payment is authorized by the Plan.
         
        
              The Plan specifically recognizes that FMR, either directly or
     through Distributors, may use its management fee revenue, past profits or
     other resources, without limitation, to pay promotional and administrative
     expenses in connection with the offer and sale of shares of the Portfolio. 
     ^ In addition, the Plan provides that FMR may use its resources, including
     its management fee revenues, to make payments to third parties that
     provide assistance in selling shares of the Portfolio or to third parties,
     including banks, that render shareholder support services.  The Trustees
     have not yet authorized ^ such payments  to date^.
         
        
              As required by the Rule, the Trustees carefully considered all
     pertinent factors relating to the implementation of the Plan prior to its
     approval, and have determined that there is a reasonable likelihood that
     the Plan will benefit the Portfolio and its shareholders.  ^ In
     particular, the Trustees noted that the Plan does not authorize payments
     by the Portfolio other than those made to FMR under its ^ management
     contract with the Portfolio.  To the extent that the Plan gives FMR and
     Distributors greater flexibility in connection with the distribution of
     shares of the Portfolio, additional sales of the Portfolio's shares may
     result.  Additionally, 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 Fidelity Money Market Trust on September
     21, 1994 as the then shareholder of the Portfolio, pursuant to an
     Agreement and Plan of Conversion approved by public shareholders of the
     Portfolio on September 21, 1994.

              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, Distributors believes
     that the Glass Steagall Act should not preclude a bank from performing
     shareholder support services, or servicing and recordkeeping functions. 
     Distributors 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 Portfolio 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 financial institutions may be required to
     register as dealers pursuant to state law.
         
        
              The Portfolio 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 portfolio of
     Fidelity Money Market Trust, an open-end management investment company
     originally organized as a Massachusetts business trust by Declaration of
     Trust dated August 21, 1978 ^  and amended and restated November 1, 1989. 
     On October 18, 1994 the Trust was converted to a Delaware business trust
     pursuant to an agreement approved by shareholders on September 21, 1994. 
     The Delaware trust, which was organized on June 20, 1991 under the name of
     Fidelity Money Market Trust I, succeeded to the name Fidelity Money Market
     Trust on October 18, 1994.  Currently there are five portfolios of the
     Trust: U.S. Treasury Portfolio^ ; U.S. Government Portfolio^; Domestic
     Money Market Portfolio^; Retirement Money Market Portfolio; and Retirement
     Government Money Market Portfolio.  The ^ Trust Instrument permits the
     Trustees to create additional ^ series.
         
        
     In the event that FMR ceases to be the investment adviser to the Trust or
     a portfolio, the right of the Trust or portfolio to use the identifying
     name "Fidelity" may be withdrawn.

     The assets of the Trust, received for the issue or sale of shares of each
     portfolio and all income, earnings, profits, and proceeds thereof, subject
     only to the rights of creditors, are especially allocated to such
     portfolio, and constitute the underlying assets of such portfolio.  The
     underlying assets of each portfolio are segregated on the books of
     account, and are to be charged with the liabilities with respect to such
     portfolio 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 portfolios, 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 portfolio, or which are
     general or allocable to all of the portfolios.  In the event of the
     dissolution or liquidation of the Trust,  shareholders of each portfolio
     are entitled to receive as a class the underlying assets of such portfolio
     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 portfolio's property of any shareholder or
     former shareholder  held personally liable for the obligations of the
     portfolio.  The ^ Trust Instrument also provides that each portfolio
     shall, upon request, assume the defense of any claim made against any
     shareholder for any act or obligation of the portfolio 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 a portfolio is unable to meet its
     obligations.  FMR believes that, in view of the above, the risk of
     personal liability to shareholders is remote.
         
        
     The ^ Trust Instrument further provides that the Trustees, if they have
     exercised reasonable care, will not be liable ^ to any person other than
     the Trust or its shareholders; moreover, the Trustees shall not be liable
     for any conduct whatsoever provided that the 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 portfolio's capital consists of shares of
     beneficial interest.  As a shareholder, you receive one vote for each
     dollar of net asset value you own.  The shares have no preemptive or

                                        - 27 -
<PAGE>






     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 ^ portfolio may, as set forth
     in the ^ Trust Instrument, call meetings of the Trust or a ^ portfolio for
     any purpose related to the Trust or ^  portfolio, 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 ^ portfolio may be terminated upon the sale of its assets
     to, or merger with, another open-end management investment company, 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 portfolio, as determined by the current value of each
     shareholder's investment in the portfolio 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 ^ each portfolio 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's registration
     statement.  Each portfolio may invest all of its assets in another
     investment company.
         
        
     As of ^ September __, 1994 the following owned of record or beneficially ^
     5% or more of outstanding shares: [to be added] 
         
        
         CUSTODIAN.  Morgan Guaranty Trust Company of New York, 60 Wall Street,
     New York, NY, is custodian of the assets of the Portfolio.  The custodian
     is responsible for the safekeeping of the Trust's assets and the
     appointment of subcustodian banks and clearing agencies.  The custodian
     takes no part in determining the investment policies of ^ the Portfolio or
     in deciding which securities are purchased or sold by the Portfolio.  The
     Portfolio, however, may invest in obligations of the custodian and may
     purchase securities from or sell securities to the custodian.  
         
     FMR, its officers and directors and its affiliated companies and the
     Trust's Trustees may from time to time have transactions with various
     banks, including banks serving as custodians for certain of the portfolios
     advised by FMR.  Transactions that have occurred to date have included
     mortgages and personal and general business loans.  In the judgment of
     FMR, the terms and conditions of these transactions were not influenced by
     existing or potential custodial or other Portfolio relationships.

     AUDITOR.  ^_____________, serves as the Trust's independent accountant.
     The auditor examines financial statements for the ^  Portfolio and
     provides other audit, tax, and related services.
         
        
                                FINANCIAL STATEMENTS 

     The Portfolio's financial statements and financial highlights for the
     fiscal year ended August 31, 1994, are included in the Portfolio's annual
     report, which is a separate report attached to the prospectus.  The
     Portfolio's financial statements and financial highlights are incorporated
     herein by reference. 
         
                                       APPENDIX

     The descriptions that follow are examples of eligible ratings for the
     Portfolio. The Portfolio, 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:
        
              o       ^ Leading market positions in well established
                      industries.
              o       ^ High rates of return on funds employed.
              o       ^ Conservative capitalization structures with moderate
                      reliance on debt and ample asset protection.
              o       ^ Broad margins in earnings coverage of fixed financial
                      charges and high internal cash generation.
              o       ^ 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.


              A-1--This designation indicates that the degree of safety
     regarding timely 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 designated A-1.

                            SUMMARY OF PORTFOLIO EXPENSES

              The purpose of the table below is to assist investors in
     understanding the various costs and expenses that an investor in the
     Portfolio would bear directly or indirectly. This standard format was
     developed for use by all mutual funds to help investors make their
     investment decisions. This expense information should be considered along
     with other important information, such as the Portfolio's investment
     objective and past performance. There are no transaction expenses
     associated with purchases or sales of the Portfolio's shares. 
        
                      A.       ANNUAL OPERATING EXPENSES 
              (as a percentage of average net assets)

              Management Fees  ^.__%
              Other Expenses   .00
         
        
                      TOTAL OPERATING EXPENSES
                      ^.__%
         
              B.      Example: You would pay the following expenses on a $1,000
     investment, assuming (1) a 5% annual return and (2) redemption at the end
     of each time period:
        
              1 Year  3 Years  5 Years 10 Years
              ^ $__            $__              $__              $__
         
     EXPLANATION OF TABLE:
        
              A.      ANNUAL OPERATING EXPENSES. Annual operating expenses are
     based on the Portfolio's expenses for the last fiscal year. Management ^
     fees are paid by the Portfolio to Fidelity Management & Research Company
     (FMR) for managing its investments and business affairs. FMR is
     responsible for the payment of all of the expenses of the Portfolio with
     the exception of certain limited expenses. Management fees and other
     expenses already have been reflected in the Portfolio's share price and
     dividends and are not charged directly to individual shareholder accounts.
     Please refer to the section "Management Contract, Distribution and Service
     Plan" on page 15 for further information.
         
        
              B.      EXAMPLE OF EXPENSES. The hypothetical example illustrates
     the expenses associated with a $1,000 investment over periods of 1, 3, 5
     and 10 years, based on the expenses in the table and an assumed annual
     rate of return of 5%.  ^ THE RETURN OF 5% AND EXPENSES SHOULD NOT BE
     CONSIDERED INDICATIONS OF ACTUAL OR EXPECTED PORTFOLIO PERFORMANCE OR
     EXPENSES, BOTH OF WHICH MAY VARY.

     INVESTMENT OBJECTIVE AND POLICIES
        
              Retirement Government Money Market Portfolio's investment
     objective is to obtain as high a level of current income as is consistent
     with the preservation of capital and liquidity. FMR will buy obligations
     for the Portfolio consistent with ^ its investment objective, and which
     meet the quality standards established for the Portfolio. The Portfolio's
     investment objective is fundamental and may not be changed without the
     affirmative vote of a majority of the outstanding shares of the Portfolio.
     No assurance can be made that the Portfolio will achieve its objective,
     but it will follow the investment style described in the following
     paragraphs.
         
        
              The Portfolio 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. The Portfolio may ^  engage in short sales against
     the box, repurchase agreements and in reverse repurchase agreements with
     respect to such obligations. The Portfolio itself is not guaranteed by the
     U.S. government.
         
        
              U.S. Treasury notes and bills and certain agency securities, such
     as those issued by the Federal Housing Administration, are backed by the
     full faith and credit of the U.S. government. The Portfolio also may
     invest in securities issued by government agencies or instrumentalities
     (such as executive departments of the government or independent federal
     organizations supervised by Congress), which may have different degrees of
     government backing but which are not backed by the full faith and credit
     of the U.S. government. For example, securities issued by the Federal Farm
     Credit Bank System and the Federal National Mortgage Association are
     supported by the agency'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. There is no guarantee that the U.S. government will support U.S.
     government agency securities, and, accordingly, they may involve a risk of
     nonpayment of principal and interest.
         
        
              MATURITY.  The Portfolio must limit its investments to securities
     with remaining maturities of 397 days or less and must maintain a
     dollar-weighted average maturity of 90 days or less.
         
        
              INVESTMENT LIMITATIONS.  The following summarizes the Portfolio's
     principal investment limitations.  A complete listing is contained in the
     SAI.
         
        
              1  With respect to 75% ^ of its total assets, ^ the Portfolio may
     not invest more than 5% of its total assets in the securities of any one
     issuer (other than U.S. government securities).

                                        - 5 -                         prospectus
<PAGE>






         
        
              2. The Portfolio may not purchase the securities of any issuer
     (other than U.S. government securities), if as a result, more than 25% of
     its total assets would be invested in issuers whose principal business
     activities are in the same industry.
         
        
              3. The Portfolio may (a) borrow money for temporary or emergency
     purposes and (b) engage in reverse repurchase agreements for any purpose;
     provided that (a) and (b) in combination do not exeed 33 1/3% of its total
     assets, (c) may borrow money from a bank or from other funds advised by
     FMR or an affiliate or by engaging in reverse repurchase agreements and
     (c) may not purchase securities when borrowings (other than reverse
     repurchase agreements) exceed ^ 5% of its total assets.
         
        
              Except for the Portfolio's investment objective and ^ limitation
     ^ 1, 2, 3(a), and 3(b), the investment policies described in this
     Prospectus are not fundamental. Non-fundamental  investment policies may
     be changed without shareholder approval. Fundamental investment policies
     may not be changed without the affirmative vote of a majority of the
     outstanding shares of the Portfolio. Except for the percentage limitation
     (a) above, these limitations and policies are considered at the time of
     purchase; the sale of securities is not required in the event of a
     subsequent change in circumstances. A complete listing of the  Portfolio's
     investment limitations is contained in the ^ SAI.
         
        
              SUITABILITY. The Portfolio's ability to achieve its investment
     objective depends on the quality and maturity of its investments. Although
     the Portfolio's investment policies are designed to help maintain a stable
     $1.00 share price, all money market instruments can change in value when
     interest rates or issuers' creditworthiness change, or if an issuer or
     guarantor of a security fails to pay interest or principal when due. If
     these changes in value were large enough, the Portfolio's share price
     could fall below $1.00. In general, securities with longer maturities are
     more ^ sensitive to interest rate changes than are short-term securities,
     although long-term securities may provide higher yields.
         
        
              If you seek income at current money market rates while remaining
     conveniently liquid, the Portfolio may be appropriate for you. It provides
     the added safety of investments in U.S. government and agency obligations.
     The Portfolio generally is designed for investors in tax-saving retirement
     plans such as Defined Contribution Plans, 403(b) Custodial Accounts,
     Defined Benefit Plans and 457 Plans. Minimum investments for these plans
     may differ from those listed on page__.
         
              By itself, the Portfolio does not constitute a balanced
     investment plan; its objective stresses income with preservation of


                                        - 6 -                         prospectus

     capital and liquidity, and not the higher yields or capital appreciation
     that may be available from more aggressive investments.

     HOW TO INVEST, EXCHANGE AND REDEEM
        
              Shares of the Portfolio are offered continuously and may be
     purchased at the next determined net asset value per share (NAV)  ^ after
     an order is received and accepted. The Portfolio's shares are sold without
     a sales charge, although institutions may charge their clients fees in
     connection with purchases and sales for the accounts of their clients. The
     NAV of the Portfolio is determined by adding the value of all securities
     and other assets of the Portfolio, deducting its actual and accrued
     liabilities, and dividing by the number of shares outstanding. The
     Portfolio values its securities on the basis of amortized cost. Fidelity
     Service Co. (Service), calculates ^ NAV at the close of the Portfolio's
     business day, which coincides with the close of business of the New York
     Stock Exchange (NYSE), normally 4:00 p.m. Eastern Time (4 p.m.). (See the
     holiday schedule on page ^  12.) You begin to earn dividends as of the
     first business day following the day of your purchase.
         
              MINIMUM INVESTMENT AND ACCOUNT BALANCE. The minimum initial
     investment to establish a new account in the Portfolio is $100,000.
     Subsequent investments may be in any amount. If you want to keep your
     account open, please leave $100,000 in it. If your account balance falls
     below $100,000 due to redemption, your account may be closed and the
     proceeds mailed to you at the record address. You will be given 30 days'
     notice that your account will be closed unless you make an additional
     investment to increase your account balance to the $100,000 minimum. The
     minimum investment requirements may differ or may not apply to
     participants of tax-saving retirement plans. 
        
              If you are purchasing shares of the Portfolio through a
              program of services offered by a securities dealer,
              financial or other institution, you should read the
              program materials in conjunction with this Prospectus.
              Certain features of the Portfolio ^ may be modified in
              these programs and administrative charges may be imposed
              for the services rendered.
                  
        
              If you invest in this Portfolio through an employer-
              sponsored retirement plan, some of the instructions,
              shareholder services and phone numbers that follow will
              not apply. Speak to ^ your institutional representative
              for additional information.
         
        
              HOW TO INVEST. An initial investment in the Portfolio must be
     preceded or accompanied by a completed, signed application.^ Additional
     paperwork may be required from corporations, associations and certain
     fiduciaries.

     are accepted by the Portfolio's custodian wire bank. It is recommended
     that investors wire funds early in the day to ensure proper credit.

              HOW TO EXCHANGE. An exchange is a convenient way to buy shares of
     the Portfolio or other Fidelity funds. The Fidelity family of funds has a
     variety of investment objectives. You may exchange shares of this
     Portfolio for shares of other Fidelity funds (subject to the minimum

                                        - 8 -                         prospectus

     initial investment requirement) that are registered in your state. When
     making an exchange, the name, address and tax identification numbers of
     the two accounts must be identical. Investors must consult the prospectus
     of the fund to be acquired to determine eligibility and suitability. To
     protect the Portfolio's performance and shareholders, Fidelity discourages
     frequent trading in response to short-term market fluctuations. In
     particular, exchanges that coincide with "market timing" strategies can
     have adverse effects on the funds.
        
              You may exchange all or any part of the value of your accounts on
     any business day. There is currently no limit on exchanges out of the
     Portfolio^; however, exchange limits may apply to other funds. Exchanges
     may be requested in writing or by telephone and are effected at the NAV
     next determined after receipt of the exchange request. 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 already have paid in
     connection with the shares you are exchanging. This may not apply if you
     are investing through a tax-saving retirement plan.
         
              Each exchange actually represents the sale of shares of one fund
     and the purchase of shares in another, which may produce a gain or loss
     for tax purposes. A confirmation of each exchange transaction will be sent
     to you. In order to allow FMR to manage the Portfolio most effectively,
     you are strongly urged to initiate exchanges of shares as early in the day
     as possible.

              TO EXCHANGE BY TELEPHONE. Exchanges may be requested by calling:

              Retirement Plan Accounts          800-962-1375
              Financial and Other Institutions  800-843-3001
        
              TO EXCHANGE BY MAIL. Written requests for exchanges should
     contain the Portfolio name, account number and number of shares to be
     redeemed, and the ^ name of the fund whose shares ^ are being purchased.
     The request must be signed by a person authorized to act on behalf of the
     account. Letters should be sent to: 
         

              Fidelity Money Market Trust:
              Retirement Government Money Market Portfolio
              c/o Fidelity Institutional Retirement Services Company
              P.O. Box 650488
              Dallas, TX 75265-0488

              The Portfolio reserves the right at any time without prior notice
     to refuse exchange purchases by any person or group if, in FMR's judgment,
     the Portfolio would be unable to invest effectively in accordance with its
     investment objective and policies or would otherwise potentially be
     adversely affected. The Portfolio may terminate or modify the exchange
     privilege in the future.

              HOW TO REDEEM. You may redeem all or a portion of your shares on
     any business day. Your shares will be redeemed at the next determined NAV
     calculated after the Portfolio has received and accepted your redemption
     request. When you redeem shares, the Portfolio normally will send you the
     proceeds on the next business day. Shares will earn dividends through the
     date of redemption; however, shares redeemed on a Friday or prior to a
     holiday will continue to earn dividends until the next business day. The
     Portfolio may hold payment on redemptions until it is reasonably satisfied
     that investments made by check have been collected (which could take up to
     seven days).
        
              TO REDEEM BY WIRE. The wiring of redemption proceeds is available
     only to investors who have previously established a wire account. In
     addition to the Portfolio's holiday schedule, (see page ^ 12) shares
     cannot be redeemed by wire on Dr. Martin Luther King, Jr. Day (observed),
     Columbus Day (observed), Veteran's Day (observed) or during any
     unscheduled closings of the Federal Reserve Wire System. Shares redeemed
     will not receive the dividend declared on the day of redemption.
         
              TO REDEEM BY MAIL. Send a letter of instruction with your
     signature(s) guaranteed to the address given above. The letter should
     specify the name of the Portfolio, the number of shares to be redeemed,
     your name, your account number, and should include the additional
     requirements listed below that apply to your particular account.

              If you do not fall into any of these registration categories,
     (e.g., Executors, Administrators, Conservators, Guardians) please call
     Client Administration for further instructions.

              A signature guarantee is a widely accepted way to protect you and
     Fidelity Investments Institutional Operations Company (FIIOC) by verifying
     the signature on your redemption request; it may not be provided by a
     notary public. Signature guarantees will be accepted from banks, brokers,
     dealers, municipal securities dealers, municipal securities brokers,
     government securities dealers, government securities brokers, credit
     unions (if authorized under state law), national securities exchanges,
     registered securities associations, clearing agencies and savings
     associations.

              TO REDEEM BY TELEPHONE. You may redeem shares of the Portfolio by
     instructing FIIOC to have the proceeds of redemptions wired directly to
     your designated bank account(s). To redeem by telephone call FIIOC before
     4 p.m.:

              Retirement Plan Accounts          800-962-1375
              Financial and Other Institutions  800-843-3001

     Provided that your account registration has not changed within the last 60
     days, you may redeem shares of the Portfolio worth $25,000 or less by
     calling Institutional Trading. Redemption proceeds will be sent to the
     record address.

              If making immediate payment could adversely affect the Portfolio,
     it may take up to seven (7) days to pay you. Also, when the NYSE is closed


                                        - 11 -                        prospectus

     (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 Portfolio may suspend
     redemption or postpone payment dates. If you are unable to execute your
     transaction by telephone (for example, during times of unusual market
     activity), consider placing your order by mail.

              In order to allow FMR to manage the Portfolio most effectively,
     investors are strongly urged to initiate redemptions of shares as early in
     the day as possible and to notify the Portfolio at least one day in
     advance of large redemptions. 

              ADDITIONAL INFORMATION. You may initiate many transactions by
     telephone. Note that Fidelity will not be responsible for any losses
     resulting from unauthorized transactions if it follows 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 your confirmation
     statements immediately after you receive them. If you do not want the
     ability to redeem and exchange by telephone, call Fidelity for
     instructions.
        
              The Portfolio reserves the right to suspend the offering of
     shares for a period of time. The Portfolio also reserves the right to
     reject any specific purchase order, including certain purchases by
     exchange (see "How to Exchange" on page ^ 8). Purchase orders may be
     refused if, in FMR's opinion, they are of a size that would disrupt
     management of the Portfolio.
         

     SHAREHOLDER SERVICES
        
              TAX-SAVING RETIREMENT PLANS. Fidelity can set up your new account
     in the Portfolio under one of several tax-sheltered plans. These plans let
     you save for retirement and shelter your investment income from current
     taxes. Minimums may differ from those listed on page 7 and the
     corresponding information may not apply. Retirement plan participants
     should refer to their retirement plan's guidelines for further
     information.

     CHOOSING A DISTRIBUTION OPTION

              When you fill out the application for your account, you can
     choose from two distribution options.

              A.      The SHARE OPTION reinvests your distributions in
     additional shares. You are assigned this option automatically if you make
     no choice on your application.

              B.      The INCOME-EARNED OPTION distributes all dividends in
     cash to you.
        
     Participants in the above mentioned tax-saving retirement plans can elect
     to take their distributions in kind and establish an IRA rollover account
     ^ in the Portfolio.
         
              SUBACCOUNTING AND SPECIAL SERVICES. Special processing has been
     arranged with FIIOC for banks, corporations and other institutions that
     wish to open multiple accounts (a master account and subaccounts). An
     investor wishing to utilize FIIOC's subaccounting facilities or other
     special services for individual or multiple accounts may be required to
     enter into a separate agreement with FIIOC. Charges for these services, if
     any, will be determined on the basis of the level of services to be
     rendered. Subaccounts may be opened with the initial investment or at a
     later date and may be established by an investor with registration either
     by name or by number.

              The Portfolio pays for shareholder services, but not for special
     services, such as a request for a historical transcript of an account. You
     may be required to pay a fee for these special services.
        
              STATEMENTS AND REPORTS. The Portfolio will send a statement of
     your account after every transaction that affects your share balance or
     your account registration. The Portfolio does not issue share
     certificates. Dividend statements are mailed quarterly. At least twice a
     year you will receive financial statements of the Portfolio. To reduce
     expenses, only one copy of most fund reports (such as the Portfolio's ^
     Annual Report) will be mailed to your household. Write to the Portfolio if
     you need to have additional reports sent each time.

     Administration.
         
        
              HOLIDAY SCHEDULE. The Portfolio is open for business and its NAV
     is calculated every day the NYSE is open for trading. The NYSE has
     designated the following holiday closings for ^ 1994: Presidents' Day,
     Good Friday, Memorial Day^, Independence Day^, Labor Day, Thanksgiving
     Day, and Christmas Day. Although FMR expects the same holiday schedule,
     with the addition of New Year's Day, to be observed in the future, the
     NYSE may modify its holiday schedule at any time. On any day ^ that the
     NYSE closes early, or as permitted by the SEC, or on any day that the
     principal government securities markets close early, such as on days in
     advance of holidays generally observed by participants in such markets,
     the right is reserved to advance the time on that day by which purchase
     and redemption requests must be received. To the extent that ^ portfolio
     securities are traded in other markets on days the NYSE is closed, the
     Portfolio's NAV may be affected on days when investors ^ do not have
     access to the Portfolio to purchase or redeem shares. Certain ^ Fidelity
     funds may follow different holiday ^ schedules.
         
     DISTRIBUTIONS AND TAXES

              The Portfolio ordinarily declares dividends from net investment
     income daily and pays such dividends monthly. The Portfolio intends to
     distribute substantially all of its net investment income and capital
     gains, if any, to shareholders within each calendar year as well as on a
     fiscal year basis.
        
              FEDERAL TAXES. Dividends derived from net investment income and
     short-term capital gains are taxable as ordinary income. The Portfolio's
     distributions are taxable when they are paid, whether you take them in
     cash or reinvest them in additional shares, except that distributions
     declared in December and paid in January are taxable as if paid on
     December ^ 31. The Portfolio will send you an ^ Internal Revenue Service
     (IRS) Form 1099-DIV by January ^ 31 showing your taxable distributions for
     the past calendar year.
         
        
              STATE AND LOCAL TAXES^. Mutual fund dividends from ^ U.S.
     government securities generally are 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. Some states may
     impose intangible property taxes. 
     ^
         
        
              OTHER TAX INFORMATION. The information above is only a summary of
     some of the ^ tax consequences generally affecting the Portfolio and its
     shareholders, and no attempt has been made to discuss individual tax
     consequences. In addition to federal tax,  ^ shareholders may be subject

     to state or local taxes on ^ their investments.  Investors should consult
     their tax advisors for details and up-to-date information on the tax laws
     in their state to determine whether the Portfolio is suitable to their
     particular tax situation.
         
              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 Portfolio to withhold 31% of distributions from your account.

     Your tax situation may be different if you are investing through a
     tax-saving retirement plan. Contact your tax adviser or plan administrator
     for further information.

     PORTFOLIO TRANSACTIONS
        

     Money market obligations generally are traded in the ^  over-the-counter
     market through broker-dealers. A broker-dealer is a securities firm or
     bank which makes a market for securities by offering to buy at one price
     and sell at a slightly higher price. The difference between the prices is
     known as a spread. Since FMR trades, directly or through affiliated
     sub-advisers, a large number of securities, including those of Fidelity's
     other funds, broker-dealers are willing to work with the Portfolio on a
     more favorable spread than would be possible for most individual
     investors.
         
              The Portfolio has authorized FMR to allocate transactions to some
     broker-dealers who help distribute the shares of the Portfolio or shares
     of Fidelity's other funds to the extent permitted by law, and on an agency
     basis to an affiliate, Fidelity Brokerage Services, Inc. (FBSI). FMR will
     allocate such transactions if commissions are comparable to those charged
     by non-affiliated qualified broker-dealers for similar services.

              Higher commissions may be paid to those firms that provide
     research services to the extent permitted by law. FMR also is authorized
     to allocate brokerage transactions to FBSI in order to secure from FBSI
     research services produced by third party, independent entities. FMR may
     use this research information in managing the Portfolio's assets, as well
     as assets of other clients.

     PERFORMANCE

              The Portfolio advertises its YIELD and EFFECTIVE YIELD in
     advertisements or in reports or other communications to shareholders. Both
     yield figures are based on historical earnings and are not intended to
     indicate future performance.
        
              The Portfolio's yield refers to the income generated by an
     investment in the Portfolio over a seven-day period expressed as an annual
     percentage rate. The Portfolio also may calculate an  EFFECTIVE YIELD by

                                        - 15 -                        prospectus
<PAGE>






     compounding the base period return over a one- year period. The effective
     yield, although calculated similarly, will be slightly higher than the
     yield because it assumes that income earned from the investment is
     reinvested (i.e., the compounding effect of reinvestment). For the
     seven-day period ended August 31, ^ 1994, the Portfolio's yield was ^
     x.xx% and its effective yield was ^ x.xx%.
         
              The Portfolio's TOTAL RETURN is based on the overall dollar or
     percentage change in value of a hypothetical investment in the Portfolio
     and assumes all distributions are reinvested.

              A CUMULATIVE TOTAL RETURN reflects the Portfolio's performance
     over a stated period of time. 

              An AVERAGE ANNUAL TOTAL RETURN reflects the hypothetical annually
     compounded rate that would have produced the same cumulative total return
     if the Portfolio's performance had been constant over the entire period.
     Because average annual returns tend to smooth out variations in the
     Portfolio's return, investors should recognize that they are not the same
     as actual year-by-year results. 


     MANAGEMENT CONTRACT, DISTRIBUTION AND SERVICE PLAN
        
              MANAGEMENT CONTRACT. For managing its investments and business
     affairs, the Portfolio pays a monthly management fee to FMR at the annual
     rate of .42% of the average net assets of the Portfolio throughout the
     month. FMR pays all expenses of the Portfolio with the following
     exceptions: the payment of fees and expenses of all Trustees of the Trust
     who are not "interested persons" of the Trust or FMR; brokerage fees or
     commissions (if any); interest on borrowings; taxes; and such
     extraordinary non- recurring expenses as may arise, including litigation
     to which the Portfolio may be a party. The management fee will be reduced
     by the ^ fees and expenses of those Trustees who are not " interested
     persons" of the Trust paid by the Portfolio. For the fiscal year ended
     August 31, ^ 1994, the Portfolio paid FMR ^  $x,xxx,xxx in management fees
     before reduction for ^ the fees and expenses of the non-interested members
     of the Board of Trustees.
         
              FMR has entered into a sub-advisory agreement with FMR Texas Inc.
     (FMR Texas), under which FMR Texas has primary responsibility for
     providing portfolio investment management services, while FMR retains
     responsibility for providing other management services. Under the terms of
     the agreement, FMR pays FMR Texas fees equal to 50% of the management fees
     payable to FMR under its current management contract with the Portfolio.
     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.
        
              FIIOC performs transfer agency, dividend disbursing and
     shareholder servicing functions for the Portfolio. Service calculates the
     Portfolio's NAV and dividends, and maintains the Portfolio's general
     accounting records. The costs of providing these services are borne by FMR

                                        - 16 -                        prospectus
<PAGE>






     pursuant to its ^ management contract with the Portfolio. Both FIIOC and
     Service are affiliates of FMR.
         
              FMR may, from time to time, agree to reimburse the Portfolio for
     expenses above a specific percentage of average net assets. FMR retains
     the ability to be repaid by the Portfolio for these expense reimbursements
     in the amount that expenses fall below the limit prior to the end of the
     fiscal year. Fee reimbursements by FMR will increase the Portfolio's
     yield, and subsequent repayment by the Portfolio will lower its yield.
        
              DISTRIBUTION AND SERVICE PLAN. The ^ Board of Trustees, on behalf
     of the ^ Portfolio, has adopted a Distribution and Service Plan (the Plan)
     ^ pursuant to Rule 12b-1 (the Rule) ^ under the Investment Company Act of
     1940 (1940 Act). The Rule provides in substance that a mutual fund may not
     engage directly or indirectly in financing any activity that is intended
     primarily to result in the sale of shares of the fund except pursuant to a
     plan adopted by the fund under the Rule. No separate payments are
     authorized to be made by the Portfolio under the Plan. Rather, the Plan
     recognizes that FMR may use its management fee or other resources to pay
     expenses associated with activities primarily intended to result in the
     sale of the Portfolio's shares^.

         
        
              THE TRUST AND THE FIDELITY ORGANIZATION. The Portfolio is a
     diversified portfolio of Fidelity Money Market Trust, an open-end,
     management investment company organized as a ^ Delaware business trust by
     a Trust Instrument dated June 20, 1991. The Board of Trustees of the Trust
     supervises Trust activities and reviews contractual arrangements with
     companies that provide the Portfolio with services. The Trust is not
     required to hold annual shareholder meetings, although special meetings
     may be called for a specific Portfolio or the Trust as a whole for
     purposes such as electing or removing Trustees, changing fundamental
     investment policies, or approving a new or amended management contract. As
     a shareholder, ^ the number of votes you  are entitled to is based on the
     dollar value of your investment. 
         
              Fidelity Investments is one of America's largest investment
     management organizations and has its principal business address at 82
     Devonshire Street, Boston, MA 02109. It is composed of a number of
     different subsidiaries and divisions which provide a variety of financial
     services and products. The Trust employs various Fidelity companies to
     perform certain activities required for its operation.
        
              FMR is the original Fidelity company, founded in 1946. It
     provides a number of mutual funds and other clients with investment
     research and portfolio management services. FMR maintains a large staff of
     experienced investment personnel and a full complement of related support
     facilities. As of August 31, ^ 1994, FMR advised funds having more than ^
     xx million shareholder accounts with a total value of more than ^ $xxx
     billion. Fidelity Distributors Corporation (Distributors) distributes
     shares for the Fidelity funds.

              FMR Corp. is the ultimate parent company ^ of FMR and FMR Texas. 
     Through ownership of voting common stock, members of the Edward C. Johnson
     3d ^ family form a controlling group with respect to FMR Corp.  Changes
     may occur in the Johnson family group, through death or disability, which
     would result in changes in each individual family members' holding of
     stock.  Such changes could result in one or more family members becoming
     holders of over 25% of the stock.  FMR Corp. has received an opinion of
     counsel that changes in the composition of the Johnson family group under
     these circumstances would not result in the termination of the Portfolio's
     management or distribution contracts and, accordingly, would nor require a
     shareholder vote to continue operation under those contracts.
         
              APPENDIX 

              The following paragraphs provide a brief description of
     securities in which the Portfolio may invest and transactions it may make.
     The Portfolio is not limited by this discussion, however, and may purchase
     other types of securities and enter into other types of transactions if
     they are consistent with the Portfolio's investment objective and
     policies.
        
              A complete listing of the Portfolio's policies and limitations
     and more detailed information about the Portfolio's investments are
     contained in the Portfolio's SAI.  Current holdings and recent investment
     strategies are described in the Portfolio's financial report, which is
     sent to shareholders twice a year.
         

              DELAYED DELIVERY TRANSACTIONS. The Portfolio may buy and sell
     securities on a when-issued or delayed delivery basis, with payment and
     delivery taking place at a future date. The market value of securities
     purchased in this way may change before the delivery date, which could
     affect the market value of the Portfolio's assets. Ordinarily, the
     Portfolio will not earn interest on securities purchased until they are
     delivered.
        
              ILLIQUID INVESTMENTS.^  Under the supervision of the Board of
     Trustees, FMR determines the liquidity of the Portfolio's investments. The
     absence of a trading market can make it difficult to ascertain a market
     value for illiquid investments. It may be difficult or impossible for the
     Portfolio to sell illiquid investments promptly at an acceptable price.
         
              INTERFUND BORROWING PROGRAM. The Portfolio has received
     permission from the SEC to lend money to and borrow money from other funds
     advised by FMR or its affiliates, but it will participate in the interfund
     borrowing program only as a borrower. Interfund loans normally will extend
     overnight, but can have a maximum duration of seven days. The Portfolio
     will borrow through the program only when the costs are equal to or lower
     than the cost of bank loans. The Portfolio will not borrow through the
     program if, after doing so, total outstanding borrowings would exceed 15%

                                        - 18 -                        prospectus
<PAGE>






     of total assets. Loans may be called on one day's notice, and the
     Portfolio may have to borrow from a bank at a higher interest rate if an
     interfund loan is called or not renewed.

              REPURCHASE AGREEMENTS. In a repurchase agreement, the Portfolio
     buys a security at one price and simultaneously agrees to sell it back at
     a higher price. In the event of the bankruptcy of the other party to a
     repurchase agreement the Portfolio could experience delays in recovering
     its cash. To the extent that, in the meantime, the value of the securities
     purchased had decreased, the Portfolio could experience a loss. In all
     cases, FMR must find the creditworthiness of the other party to a
     transaction satisfactory. 
        
              REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement,
     the Portfolio temporarily transfers possession of a portfolio instrument
     to another party, such as a bank or broker- dealer, in return for cash. At
     the same time, the Portfolio agrees to repurchase the instrument at an
     agreed upon price and date. The Portfolio expects that it will engage in
     reverse repurchase agreements for temporary purposes such as funding
     redemptions, or when it is able to invest the cash so acquired at a rate
     higher than the cost of the agreement. Reverse repurchase agreements may
     increase the risk of fluctuation in the market value of the Portfolio's
     assets or its yield.
         
        
              STRIPPED GOVERNMENT SECURITIES are created by separating the
     income and principal components of a debt instrument and selling them
     separately.  The Portfolio may purchase U.S. Treasury STRIPS (Separate
     Trading of Registered Interest and Principal of Securities), that are
     created when the coupon payments and the principal payment are stripped
     from an outstanding Treasury bond by the Federal Reserve Bank of New York.
         
        
              VARIABLE OR FLOATING RATE OBLIGATIONS ^ provide for periodic
     adjustments of the interest rates paid.  Floating rate obligations have
     interest rates that change whenever there is a change in a designated base
     rate, while variable rate obligations provide for a specified periodic
     adjustment in the interest rate.  These formulas are designed to result in
     a market value for the instrument that approximates its par value.  When
     determining the maturity of a variable or floating rate ^ obligation, the
     ^  Portfolio may look to the date the demand feature can be exercised, or
     to the date the interest rate is readjusted, rather than to the final
     maturity of the ^ obligation.

                         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 Portfolio'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 Portfolio'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 Portfolio's
     investment policies and limitations.
        
              The Portfolio's fundamental investment policies and limitations
     can not 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 Portfolio.  However, except for the fundamental
     investment limitations set forth below, the investment policies and
     limitations described in this ^ SAI are not fundamental and may be changed
     without shareholder approval.  THE FOLLOWING ARE THE PORTFOLIO'S
     FUNDAMENTAL INVESTMENT LIMITATIONS SET FORTH IN THEIR ENTIRETY.  THE
     PORTFOLIO MAY NOT:
         
              (1) with respect to 75% of the Portfolio's total assets, purchase
     the security of any issuer (other than obligations issued or guaranteed by
     the government of the United States, its agencies or instrumentalities)
     if, as a result thereof: (a) more than 5% of the Portfolio's total assets
     would be invested in the securities of such issuer, or (b) the Portfolio
     would hold more than 10% of the voting securities of such issuer;
        
              (2) issue ^ senior securities, except as permitted under the
     Investment Company Act of 1940;
         
        
              ^(3) borrow money, except that the Portfolio 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 Portfolio's
     total assets (including the amount borrowed) less liabilities (other than
     borrowings).  Any borrowings that come to exceed ^ this amount will be
     redueced 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 Portfolio may be deemed 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

                                        - 3 -
<PAGE>






     government of the United States, its agencies or instrumentalities) if, as
     a result, more than 25% of the Portfolio'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 Portfolio 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 the Portfolio's 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 Portfolio 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 Portfolio^ .
         

               THE FOLLOWING LIMITATIONS ARE NOT FUNDAMENTAL AND MAY BE CHANGED
     WITHOUT SHAREHOLDER APPROVAL.

              (i)     The Portfolio 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 Portfolio will not purchase any
     security while borrowings (excluding reverse repurchase agreements)
     representing more than 5% of its total assets are outstanding.  The
     Portfolio 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 Portfolio's total assets.
        
              (ii)    The Portfolio 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 Portfolio does not currently intend to purchase any
     security if, as a result, 10% or more of its net assets would be invested

                                        - 4 -
<PAGE>






     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 Portfolio does not currently intend to purchase
     securities on margin, except that the Portfolio 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 Portfolio does not currently intend to make loans,
     but this limitation does not apply to purchases of debt securities or to
     repurchase agreements.
         
        
              ^(vi)   The Portfolio 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 Portfolio does not currently intend to purchase the
     securities of any issuer (other than securities issued or guaranteed by
     domestic or foreign governments or political subdivisions thereof) if, as
     a result, more than 5% of its total assets would be invested in the
     securities of business enterprises that, including predecessors, have a
     record of less than three years of continuous operation.
         
        
              ^(viii) The Portfolio does not currently intend to invest in oil,
     gas, or other mineral exploration or development programs or leases.
         
        
              ^(ix)   The Portfolio does not currently intend to purchase the
     securities of any issuer if those officers and Trustees of the Trust and
     those officers and directors of FMR who individually own more than 1/2 of
     1% of the securities of such issuer together own more than 5% of such
     issuer's securities.
         
        
              (x)     The Portfolio does not currently intend to invest all of
     its assets in the securities of a single open-end management investment
     company with the same fundamental investment objective, policies, and
     limitations as the Portfolio.
         
        
              For the Portfolio's policies on quality and maturity, see the
     section entitiled "Quality and Maturity" on page 5.

              AFFILIATED BANK TRANSACTIONS.  ^ The Portfolio may engage in
     transactions with ^ financial institutions that are, or may be considered
     to be, "affiliated persons" of the ^ Portfolios 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 ^ affilated 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 Portfolio may buy and sell
     securities on a delayed delivery or when-issued basis.  These transactions
     involve a commitment by the Portfolio to purchase or sell specific
     securities at a predetermined price and/or yield, with payment and
     delivery taking place after the customary settlement period for that type
     of security (and more than seven days in the future).  Typically, no
     interest accrues to the purchaser until the security is delivered. 

              When purchasing securities on a delayed delivery basis, the
     Portfolio assumes the rights and risks of ownership, including the risk of
     price and yield fluctuations.  Because the Portfolio is not required to
     pay for securities until the delivery date, these risks are in addition to
     the risks associated with the Portfolio's other investments.  If the
     Portfolio 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 Portfolio will set aside appropriate liquid assets in a
     segregated custodial account to cover its purchase obligations.  When the
     Portfolio has sold a security on a delayed delivery basis, the Portfolio
     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 Portfolio could miss a favorable
     price or yield opportunity, or could suffer a loss.

              The Portfolio 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 Portfolio's investments and, through
     reports from FMR, the Board monitors trading activity in illiquid
     instruments.  In determining the liquidity of the Portfolio'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

                                        - 6 -
<PAGE>






     of the marketplace for trades (including the ability to assign or offset
     the Portfolio's rights and obligations relating to the investment). 
     Investments currently considered by the Portfolio to be illiquid include
     repurchase agreements not entitling the holder to payment of principal and
     interest within seven days.  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 Portfolio were in a position where 10% or more of its
     net assets were invested in illiquid securities, it would seek to take
     appropriate steps to protect liquidity.
        
              QUALITY AND MATURITY.  Pursuant to procedures adopted by the
     Board of Trustees, the Portfolio may purchase only high-quality securities
     that FMR believes present minimal credit risks.  To be considered high
     quality, a security must be a U.S. government security; rated in
     accordance with appplicable 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.
         
        
              The Portfolio 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.
         
        
              REPURCHASE AGREEMENTS.  In a repurchase agreement, the Portfolio
     purchases a security and simultaneously commits to resell that security to
     the 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.  A repurchase
     agreement involves the obligation of the seller to pay the agreed upon 
     resale price, which obligation is in effect secured by the value (at least
     equal to the amount of the agreed upon resale price and marked to market
     daily) of the underlying security.  The Portfolio may engage in ^
     repurchase ^ agreements with respect to any type of security in which it
     is authorized to invest  (except that the security may have a maturity in
     excess of 397 days).  While it does not presently appear possible to
     eliminate all risks from these transactions (particularly the possibility
     of a decline in the market value of the underlying securities, as well as
     delays and costs to the Portfolio in connection with bankruptcy
     proceedings), it is the Portfolio's current policy to limit repurchase
     agreements to those parties whose creditworthiness has been reviewed and
     found satisfactory by FMR. 
         
              REVERSE REPURCHASE AGREEMENTS.   In a reverse repurchase
     agreement, the Portfolio 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 Portfolio will maintain
     appropriate liquid assets in a segregated custodial account to cover its

                                        - 7 -
<PAGE>






     obligation under the agreement.  The Portfolio 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 Portfolio's assets and may be viewed as a form of
     leverage.
        
              STRIPPED GOVERNMENT SECURITIES are created by separating the
     income and principal components of a debt instrument and selling them
     separately.  The Portfolio may purchase U.S. Treasury STRIPS (Separate
     Trading of Registered Interest and Principal of Securities), that 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 Resolution Funding Corporation (REFCORP) can also be
     stripped in this fashion.  REFCORP Strips are eligible investments for the
     Portfolios.
         
              SHORT SALES AGAINST THE BOX.  The Portfolio 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 Portfolio in
     anticipation of increased interest rates without sacrificing the current
     yield of the securities sold short.  If the Portfolio 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
     Portfolio will incur transaction costs, including interest expenses, in
     connection with opening, maintaining and closing short sales against the
     box.
        
              VARIABLE OR FLOATING RATE OBLIGATIONS ^ provide for periodic
     adjustments of the interest rate paid.  Floating rate obligations have
     interest rates that change whenever there is a change in a designated base
     rate while variable rate ^  obligations provide for a specified periodic
     adjustment in the interest rate.  These formulas are designed to result in
     a market value for the ^ instrument that approximates its par value.
         
        
              ^ Some variable or floating rate ^ obligations permit holders to
     demand payment of the unpaid principal balance plus an accrued interest
     from the issuers or certain financial intermediaries. Issuers or financial
     intermediaries who provide demand features or stand-by commitments often
     obtain letters or credit (LOCs) or other guarantees from domestic or
     foreign banks to support their repurchase commitments.  FMR may rely upon
     its evaluation of a bank's credit in determining whether to purchase an
     obligation supported by an LOC.  In evaluating a foreign bank's credit,
     FMR will consider whether adequate public information about the bank is
     available and whether the bank may be subject to unfavorable political or
     economic developements, currency controls, or other government
     restrictions that might affect the bank's ability to honor its credit
     commitment.
         

                                        - 8 -
<PAGE>






        
              When determining the maturity of a variable or floating rate
     obligation, the Portfolio may look to the date the demand feature can be
     exercised, or to the date the interest rate is readjusted, rather than to
     the final maturity of the obligation.
         
                                PORTFOLIO TRANSACTIONS
        
              All orders for the purchase or sale of portfolio securities are
     placed on behalf of the Portfolio by FMR ^ pursuant to authority contained
     in the management contract.  If FMR grants investment management authority
     to the sub-adviser (see section entitled "Management Contract and Service
     Contracts"), the sub-adviser will be 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 Portfolio 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 Portfolio may execute portfolio transactions with
     broker-dealers who provide research and execution services to the
     Portfolio ^ and 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; the availability of securities or the purchasers or
     sellers of securities; furnishing analyses and reports concerning issuers,
     industries, securities, economic factors and trends, portfolio strategy
     and performance of accounts; and effecting securities transactions and
     performing 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 Portfolio 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 Portfolio may be useful to FMR in rendering
     investment management services to the Portfolio ^ or its other clients,

                                        - 9 -
<PAGE>






     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 Portfolio.  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 Portfolio 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 Portfolio 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 Portfolio 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, Ltd. (FBSL),
     subsidiaries of FMR Corp., if the commissions are fair ^, reasonable, and
     comparable to commissions charged by ^  non-affiliated, qualified
     brokerage firms for similar services. 
         
        
              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 Portfolio and review the commissions paid by
     the Portfolio over representative periods of time to determine if they are
     reasonable in relation to the benefits to the Portfolio.
        
              From time to time ^ the Trustees will review whether the
     recapture for the benefit of the Portfolio of some portion of the
     brokerage commissions or similar fees paid by the Portfolio on portfolio
     transactions is legally permissible and advisable.  The Portfolio seeks to

                                        - 10 -
<PAGE>






     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 Portfolio to seek such recapture.
         
        
              Although the Trustees and officers of the ^ Portfolio are
     substantially the same as those of other funds managed by FMR, investment
     decisions for the Portfolio 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 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
     the Portfolio. In some cases this system could have a detrimental effect
     on the price or value of the security as far as the Portfolio is
     concerned.  In other cases, however, the ability of the Portfolio to
     participate in volume transactions will produce better executions and
     prices for the Portfolio.  It is the current opinion of the Trustees that
     the desirability of retaining FMR as investment adviser to the Portfolio
     outweighs any disadvantages that may be said to exist from exposure to
     simultaneous transactions.
         
                          VALUATION OF PORTFOLIO SECURITIES

              The Portfolio values its investments on the basis of amortized
     cost.  This technique involves valuing an instrument at its cost as
     adjusted for amortization of premium or accretion of discount rather than
     its value based on current market quotations or appropriate substitutes
     which reflect current market conditions.  The amortized cost value of an
     instrument may be higher or lower than the price the Portfolio would
     receive if it sold the instrument.

              Valuing the Portfolio's instruments on the basis of amortized
     cost and use of the term "money market fund" are permitted by Rule 2a-7
     under the 1940 Act.  The Portfolio must adhere to certain conditions under
     Rule 2a-7; these conditions are summarized in the Prospectus.

              The Board of Trustees of the Trust oversees FMR's adherence to
     SEC rules concerning money market funds, and has established procedures
     designed to stabilize the Portfolio'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 Portfolio's amortized

                                        - 11 -
<PAGE>






     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.

              During periods of declining interest rates, the Portfolio's yield
     based on amortized cost may be higher than the yield based on market
     valuations.  Under these circumstances, a shareholder in the Portfolio
     would be able to obtain a somewhat higher yield than would result if the
     Portfolio utilized market valuations to determine its NAV.  The converse
     would apply in a period of rising interest rates.

                                     PERFORMANCE

              The Portfolio'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, which 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 the funds based
     on yield. In addition to the mutual fund rankings, the fund's performance
     may be compared to mutual fund performance indices prepared by Lipper.

              The Portfolio's performance or the performance of securities in
     which it may invest may also be compared to averages published by IBC/USA
     (Publications) Inc. of Ashland, MA 01720. These averages assume
     reinvestment of distributions. The Money Fund Averages/Government, which
     is reported in the Money Fund Report, covers over 198 government money
     market funds. The Portfolio may reference the growth and variety of money
     market mutual funds and FMR's innovation and participation in the
     industry.

              The Portfolio also may compare its performance to the yields or
     averages of other money market securities as reported by the Federal
     Reserve Bulletin, by TeleRate, a financial information network, or by
     Salomon Brothers Inc., a broker-dealer firm, and to other fixed-income
     investments such as Certificates of Deposit (CDs).  The principal value
     and interest rate of CDs and money market securities are fixed at the time
     of purchase, whereas the Portfolio's yield will fluctuate.  Unlike some
     CDs and certain other money market securities, money market mutual funds
     are not insured by the FDIC.  Investors should give consideration to the
     quality and maturity of the portfolio securities of the respective
     investment companies when comparing investment alternatives.

<PAGE>






              YIELD CALCULATIONS.  The Portfolio's yield refers to the income
     generated by an investment in the Portfolio over a seven day period
     expressed as an annual percentage rate.  The effective yield, although
     calculated similarly, will be slightly higher than the yield because it
     assumes that income earned from the investment is reinvested (the
     compounding effect of reinvestment).  In addition to the current yield ,
     the Portfolio may quote yields in advertising based on any historical
     seven day periods.

              TOTAL RETURN CALCULATIONS.  Total returns quoted in advertising
     reflect all aspects of the Portfolio's return, including the effect of
     reinvesting dividends and capital gain distributions (if any).  Average
     annual returns are calculated by determining the growth or decline in
     value of a hypothetical historical investment in the  Portfolio 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 the value of the investment had been constant over the period. 
     For example, a cumulative return of 100% over ten years would produce an
     average annual return of 7.18%, which is the steady annual rate that would
     equal 100% growth on a compounded basis in ten years.  While average
     annual returns are a convenient means of comparing investment
     alternatives, investors should realize that the Portfolio's performance is
     not constant over time, but changes from year to year, and that average
     annual returns represent averaged figures as opposed to the actual
     year-to-year performance of the Portfolio. 
        
               In addition to average annual returns, the Portfolio may quote
     unaveraged or cumulative total returns reflecting the simple change in the
     value of an investment over a stated period.  Average annual and
     cumulative total returns may be quoted as percentages or as dollar amounts
     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 in order to illustrate
     the relationship of these factors and their contributions to total return. 
     Total returns, yields, and other performance information may be quoted
     numerically or in a table, graph, or similar illustration.  The
     Portfolio's cumulative total returns and average annual returns for the
     fiscal year ended August 31, ^ 1994  were as follows:

              Explanatory Notes:  With an initial investment of $10,000 made on
     ^ December 16, 1988, the net amount invested in shares of the ^ Portfolio
     was $10,000.  The cost of the initial investment ($10,000) together with
     the aggregate cost of reinvested dividends for the period covered (that
     is, their cash value at the time they were reinvested) amounted to ^
     $_______.  If distributions had not been reinvested, the amount of
     distributions earned from the Portfolio over time would have been smaller
     and the cash payments (dividends) for the period would have come to ^
     $_____.  The Portfolio did not distribute any capital gains during the
     period.
         
     The Portfolio may reference and discuss its fund number, Quotron number,
     CUSIP number, and current portfolio manager in advertising.  

              From time to time, in reports and promotional literature, the
     Portfolio's performance also may be compared to other mutual funds tracked
     by financial or business publications and periodicals.  For example, the
     Portfolio may quote Morningstar, Inc. in its advertising materials. 
     Morningstar, Inc. is a mutual fund rating service that rates mutual funds
     on the basis or risk-adjusted performance.  In addition, the Portfolio may

     quote financial or business publications and periodicals as they relate to
     portfolio management, investment philosophy, and investment techniques. 
     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.

     ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

              If the Trustees determine that existing conditions make cash
     payment 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 Portfolio'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 Portfolio 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
     exchange, or (ii) the Portfolio suspends the redemption of 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.
         
              The Portfolio 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 Portfolio would be unable
     to invest effectively in accordance with its investment objective and
     policies or might otherwise be adversely affected.

     DISTRIBUTION 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.  Dividends from the Portfolio will not normally
     qualify for the dividends-received deduction available to corporations,
     since the Portfolio's income is primarily derived from interest income and
     short-term capital gains.  Depending upon state law, a portion of the
     Portfolio's dividends attributable to interest income derived from U.S.
     government securities may be exempt from state and local taxation.  The
     Portfolio will provide information on the portion of the Portfolio's
     dividends, if any, that qualify for this exemption.

              CAPITAL GAIN DISTRIBUTIONS.  The Portfolio may distribute
     short-term capital gains once a year or more often as necessary to
     maintain its NAV at $1.00 per share or to comply with distribution
     requirements under federal tax law.  The Portfolio does not anticipate
     earning long-term capital gains on securities held by the Portfolio.

              TAX STATUS OF THE PORTFOLIO.  The Portfolio has qualified and
     intends to qualify as a "regulated investment company" under the Internal
     Revenue Code of 1986, as amended (the Code), so that the Portfolio will
     not be liable for federal income or excise taxes on net investment income
     or capital gains to the extent that these are distributed to shareholders
     in accordance with applicable provisions of the Code.
        
              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 pass through 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 pass-through benefit.  The tax
     treatment of your dividend distributions from the Portfolio will be the
     same as if you directly owned your proportionate share of the ^ U.S.
     government securities held by the Portfolio.  Because the income earned on
     most U.S. government securities in which  the Portfolio invests is exempt
     form state and local taxes, the portion of your dividends from the
     Portfolio 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.

     MANAGEMENT AND SERVICE CONTRACTS
        
              The Portfolio employs FMR to furnish investment advisory and
     other services.  Under its ^ management contract with the Portfolio, FMR
     acts as investment adviser and, subject to the supervision of the Board of
     Trustees, directs the investments of the Portfolio in accordance with its
     investment objective, policies and limitations.  FMR also provides the
     Portfolio with all necessary office facilities, equipment and personnel
     for servicing the Portfolio's investments and compensates all officers of
     the Trust, all Trustees who are "interested persons" of the Trust or of
     FMR, and all personnel of the Trust 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 Portfolio.  These services include providing facilities for
     maintaining the Portfolio's organization, supervising relations with
     custodians, transfer and pricing agents, accountants, underwriters and
     other persons dealing with the Portfolio; preparing all general
     shareholder communications and conducting shareholder relations;
     maintaining the Trust's records and the registration of the Portfolio's
     shares under federal and state law; developing management and shareholder
     services for the Portfolio; and furnishing reports, evaluations and
     analyses on a variety of subjects to the Trustees on behalf of the
     Portfolio.
         
        
              FMR pays all of the expenses of the Portfolio, except as
     described below.  Specific expenses payable by FMR include, without
     limitation, the fees and expenses of registering and qualifying the
     Portfolio and its shares for distribution under federal and state
     securities laws; expenses of typesetting for printing the Prospectus and ^
     SAI; custodian charges; auditing and legal expenses; insurance expenses;
     association membership dues; the expense of reports to shareholders;
     shareholders' meetings; and proxy solicitations.
         
        
              ^ FIIOC is transfer ^, dividend disbursing ^, and shareholders'
     servicing agent for the Portfolio.  The costs of these services are borne
     by FMR pursuant to its ^ management contract with the Portfolio.  Service
     calculates the Portfolio's NAV and dividends, and maintains the
     Portfolio's general accounting records. The costs of these services are
     also borne by FMR pursuant to its management contract with the Portfolio.
         
        
              FMR pays all other expenses of the Portfolio with the following
     exceptions:  the payment of fees and expenses of all Trustees of the Trust
     who are not "interested persons" of the Trust or FMR; interest on

                                        - 22 -

     borrowings; taxes; brokerage commissions (if any); and such nonrecurring
     expenses as may arise, including costs of litigation to which the
     Portfolio may be a party, and any obligation it may have to indemnify its
     officers and Trustees with respect to ^ litigation.
         
        
              ^ For these services and FMR's payment of the portfolio's
     expenses, the Portfolio pays a monthly management fee to FMR at the annual
     rate of .42% of the average net assets of the Portfolio throughout the
     month pursuant to a management contract approved by shareholders on
     October 26, 1989.  The management fee paid to FMR ^ is reduced by an
     amount equal to the fees and expenses of those Trustees who are not
     "interested persons" of the Trust or FMR.  For the twelve month period
     ended August 31,  1994, August 31, 1993, and the ten month period ended
     August 31, 1992,^ the Portfolio paid $__________, $5,622,803, and
     $3,902,635, ^ in management fees, respectively, before reduction for ^
     fees and expenses of the non-interested Trustees.
         
        
              SUB-ADVISER.  On behalf of the Portfolio, 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 Portfolio. Under the sub- advisory agreement, FMR  pays
     FMR Texas fees equal to 50% of the management fee retained by FMR under
     its current management contract with the Portfolio.  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.  For the twelve month ^ periods
     ended August 31, 1994 and August 31, 1993, and the ten month period ended
     August 31, 1992,^ FMR paid FMR Texas fees that amounted to $__________,
     $2,806,471, and $1,948,358, ^ respectively. 
     ^
         
        
              The Portfolio has a Distribution Agreement with Distributors,^ a
     Massachusetts corporation organized on July 18, 1960^.  Distributors 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 Distributors to use all reasonable
     efforts, consistent with its other business, to secure purchasers for
     shares of the Portfolio, which are continuously offered.  Promotional and
     administrative expenses in connection with the offer and sale of shares
     are paid by FMR.
     ^    

     DISTRIBUTION AND SERVICE PLAN
        
              The Portfolio has adopted a Distribution and Service Plan (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 the ^  fund except pursuant to a plan adopted by
     the ^ fund under the Rule.  The Trust's Board of Trustees ^ has adopted

                                        - 23 -
<PAGE>






     the Plan to allow the Portfolio and FMR to incur certain expenses that
     might be considered to constitute indirect payment by the Portfolio of
     distribution expenses.  Under the Plan, if the payment of management fees
     by the Portfolio to FMR ^ is deemed to be indirect financing by the
     Portfolio of the distribution of its shares, such payment is authorized by
     the Plan.
         
        
              The Plan specifically recognizes that FMR, either directly or
     through Distributors, may use its management fee revenue, past profits or
     other resources, without limitation, to pay promotional and administrative
     expenses in connection with the offer and sale of shares of the Portfolio. 
     ^ In addition, the Plan provides that FMR may use its resources, including
     its management fee revenues, to make payments to third parties that
     provide assistance in selling shares of the Portfolio or to third parties,
     including banks, that render shareholder support services.  The Trustees
     have not ^ authorized ^ such payments to date^.
         
        
              As required by the Rule, the Trustees carefully considered all
     pertinent factors relating to the implementation of the Plan prior to its
     approval, and have determined that there is a reasonable likelihood that
     the Plan will benefit the Portfolio and its shareholders.  ^ In
     particular, the Trustees noted that the Plan does not authorize payments
     by the Portfolio other than those made to FMR under its ^ management
     contract with the Portfolio.  To the extent that the Plan gives FMR and
     Distributors greater flexibility in connection with the distribution of
     shares of the Portfolio, additional sales of the Portfolio's shares may
     result.  Additionally, 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 Fidelity Money Market Trust on September
     21, 1994, as the then shareholder of the Portfolio pursuant to an
     Agreement and Plan of Conversion approved by public shareholders of the
     Portfolio on September 21, 1994.
         
        
              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, Distributors believes
     that the Glass Steagall Act should not preclude a bank from performing
     shareholder support services, or servicing and recordkeeping functions. 
     Distributors 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

                                        - 24 -
<PAGE>






     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 Portfolio 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 financial institutions may be required to
     register as dealers pursuant to state law. 
         
        
              The Portfolio 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 portfolio of Fidelity Money Market Trust, an open- end management
     investment company originally organized as a Massachusetts business trust
     by Declaration of Trust dated August 21, 1978, and amended and restated
     November 1, 1989.  On October 18, 1994 the Trust was converted to a
     Delaware business trust pursuant to an agreement approved by shareholders
     on September 21, 1994.  The Delaware trust, which was organized on June
     20, 1991 under the name of Fidelity Money Market Trust I, succeeded to the
     name Fidelity Money Market Trust on October 18, 1994.  Currently there are
     five portfolios of the Trust: U.S. Treasury Portfolio; U.S. Government
     Portfolio; Domestic Money Market Portfolio; Retirement Money Market
     Portfolio; and Retirement Government Money Market Portfolio.  The ^ Trust 
     Instrument permits the Trustees to create additional ^ series.
         
        
              In the event that FMR ceases to be the investment adviser to the
     Trust or a portfolio, the right of the Trust or portfolio to use the
     identifying name "Fidelity" may be withdrawn.
         
        
              The assets of the Trust, received for the issue or sale of shares
     of each portfolio and all income, earnings, profits, and proceeds thereof,
     subject only to the rights of creditors, are especially allocated to such
     portfolio, and constitute the underlying assets of such portfolio.  The
     underlying assets of each portfolio are segregated on the books of
     account, and are to be charged with the liabilities with respect to such
     portfolio 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 portfolios, 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 portfolio, or which are
     general or allocable to all of the portfolios.  In the event of the

                                        - 25 -
<PAGE>






     dissolution or liquidation of the Trust,  shareholders of each portfolio
     are entitled to receive as a class the underlying assets of such portfolio
     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 portfolio's
     property of any shareholder or former shareholder  held personally liable
     for the obligations of the portfolio.  The ^ Trust Instrument also
     provides that each portfolio shall, upon request, assume the defense of
     any claim made against any shareholder for any act or obligation of the
     portfolio 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 a portfolio is
     unable to meet its obligations.  FMR believes that, in view of the above,
     the risk of personal liability to shareholders is remote.
         
        
              The ^ Trust Instrument further provides that the Trustees, if
     they have exercised reasonable care, will not be 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 portfolio's capital consists of shares of
     beneficial interest.  As a shareholder, you receive one vote for each
     dollar of net asset value 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 portfolio may, as set forth in
     the ^ Trust Instrument, call meetings of the Trust or a portfolio for any
     purpose related to the Trust or portfolio, 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 ^ portfolio may be terminated upon the sale of
     its assets to, or merger with, another open-end management investment
     company, 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 portfolio, as determined by the current value of each
     shareholder's investment in the portfolio 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 ^ each portfolio 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's registration
     statement.  Each portfolio may invest all of its assets in another
     investment company.
         
        
              As of September __, 1994 the following ^ owned of record or
     beneficially ^ 5% or more of outstanding shares: [to be added] 
         
        
         CUSTODIAN.  Morgan Guaranty Trust Company of New York, 60 Wall Street,
     New York, NY, is custodian of the assets of the Portfolio.  The custodian
     is responsible for the safekeeping of the Trust's assets and the
     appointment of subcustodian banks and clearing agencies.  The custodian
     takes no part in determining the investment policies of ^ the Portfolio or
     in deciding which securities are purchased or sold by the Portfolio.  The
     Portfolio, however, may invest in obligations of the custodian and may
     purchase securities from or sell securities to the custodian.  
         
              FMR, its officers and directors and its affiliated companies and
     the Trust's Trustees may from time to time have transactions with various
     banks, including banks serving as custodians for certain of the portfolios
     advised by FMR.  Transactions that have occurred to date have included
     mortgages and personal and general business loans.  In the judgment of
     FMR, the terms and conditions of these transactions were not influenced by
     existing or potential custodial or other Portfolio relationships.
        
          AUDITOR.  ^_________________, serves as the Trust's independent
     accountant. The auditor examines financial statements for the ^ Portfolio
     and provides other audit, tax, and related services. 
         
                                FINANCIAL STATEMENTS 
        
     The Portfolio's financial statements and financial highlights for the
     fiscal year ended August 31, 1994 are included in the Portfolio's annual
     report, which is a separate report attached to the prospectus.  The
     Portfolio's financial statements and financial highlights are incorporated

                      Registrant
                      ------------------------------

              The Board of Trustees of Registrant is the same as the boards of
     the other Fidelity funds, each of which has Fidelity Management & Research
     Company as its investment adviser. In addition, the officers of these
     funds are substantially identical.  Nonetheless, Registrant takes the
     position that it is not under common control with these other funds since
     the power residing in the respective Boards and officers arises as the
     result of an official position with the respective funds.

     Item 26.         Number of Holders of Securities

     Item 27.         Indemnification
                      ---------------

              Article XI, Section 2 of the Declaration of Trust sets forth the
     reasonable and fair means for determining whether indemnification shall be
     provided to any past or present Trustee or officer.  It states that the
     Registrant shall indemnify any present or past Trustee or officer to the
     fullest extent permitted by law against liability and all expenses
     reasonably incurred by him in connection with any claim, action, suit or
     proceeding in which he is involved by virtue of his service as a trustee,
     an officer, or both.  Additionally, amounts paid or incurred in settlement
     of such matters are covered by this indemnification.  Indemnification will
     not be provided in certain circumstances, however.  These include
     instances of willful misfeasance, bad faith, gross negligence, and
     reckless disregard of the duties involved in the conduct of the particular
     office involved.
