Each fund is open for business each day the New York Stock Exchange (NYSE) is open. Each fund is also open for business on Good Friday.

The following information supplements the information found in the "Buying and Selling Shares" section on page 12.

Frequent purchases and sales of fund shares can harm shareholders in various ways, including reducing the returns to long-term shareholders by increasing costs to a fund (such as spreads paid to dealers who sell money market instruments to a fund) and disrupting portfolio management strategies. However, FMR anticipates that shareholders will purchase and sell fund shares frequently because each fund is designed to offer investors a liquid cash option. Accordingly, the Board of Trustees has not adopted policies and procedures designed to discourage excessive or short-term trading of fund shares and each fund accommodates frequent trading.

Each fund has no limit on purchase or exchange transactions. Each fund reserves the right, but does not have the obligation, to reject any purchase or exchange transaction at any time. In addition, FMR reserves the right to impose restrictions on purchases or exchanges at any time on conditions that are more restrictive on disruptive, excessive, or short-term trading than those that are otherwise stated in this prospectus.

The following information replaces the similar information found in the "Buying Shares" section on page 13.

A fund may reject for any reason, or cancel as permitted or required by law, any purchase orders, including exchanges.

For example, a fund may reject any purchase orders, including exchanges, from market timers or investors that, in FMR's opinion, may be disruptive to the fund.

The information regarding the four exchange limit for Spartan Municipal Money found in the "Exchanging Shares" section on page 15 is no longer applicable.

The following information replaces similar information found in the "Distribution Services" section beginning on page 31.

Each fund has entered into a distribution agreement with FDC, an affiliate of FMR. The principal business address of FDC is 82 Devonshire Street, Boston, Massachusetts 02109. FDC 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 agreements call for FDC to use all reasonable efforts, consistent with its other business, to secure purchasers for shares of the funds, which are continuously offered at NAV. Promotional and administrative expenses in connection with the offer and sale of shares are paid by FMR.

The Trustees have approved Distribution and Service Plans on behalf of each fund (the Plans) pursuant to Rule 12b-1 under the 1940 Act (the Rule). The Plans, as approved by the Trustees, allow the funds and FMR to incur certain expenses that might be considered to constitute indirect payment by the funds of distribution expenses.

Under each Plan, if the payment of management fees by the fund to FMR is deemed to be indirect financing by the fund of the distribution of its shares, such payment is authorized by the Plan. Each Plan specifically recognizes that FMR may use its management fee revenue, as well as its past profits or its other resources, to pay FDC for expenses incurred in connection with providing services intended to result in the sale of fund shares and/or shareholder support services. In addition, each Plan provides that FMR, directly or through FDC, may pay significant amounts to intermediaries, including retirement plan sponsors, service-providers and administrators, that provide those services. Currently, the Board of Trustees has authorized such payments for Municipal Money Market and Spartan Municipal Money shares.

Prior to approving each Plan, the Trustees carefully considered all pertinent factors relating to the implementation of the Plan, and determined that there is a reasonable likelihood that the Plan will benefit the fund and its shareholders. In particular, the Trustees noted that each Plan does not authorize payments by the fund other than those made to FMR under its management contract with the fund. To the extent that each Plan gives FMR and FDC greater flexibility in connection with the distribution of fund shares, additional sales of fund shares or stabilization of cash flows may result. Furthermore, certain shareholder support services may be provided more effectively under the Plans by local entities with whom shareholders have other relationships.

FDC or an affiliate may compensate, or upon direction make payments for certain retirement plan expenses to, intermediaries, including retirement plan sponsors, service-providers and administrators. A number of factors are considered in determining whether to pay these additional amounts. Such factors may include, without limitation, the level or type of services provided by the intermediary, the level or expected level of assets or sales of shares, and other factors. In addition to such payments, FDC or an affiliate may offer other incentives such as sponsorship of educational or client seminars relating to current products and issues, payments or reimbursements for travel and related expenses associated with due diligence trips that an intermediary may undertake in order to explore possible business relationships with affiliates of FDC, and/or payments of costs and expenses associated with attendance at seminars, including travel, lodging, entertainment and meals. Certain of the payments described above may be significant to an intermediary. As permitted by SEC and the National Association of Securities Dealers rules, FDC or any affiliate may pay or allow other incentives or payments to intermediaries.

Each fund's transfer agent or an affiliate may also make payments and reimbursements to certain intermediaries, including retirement plan sponsors, service providers and administrators, for providing recordkeeping and administrative services to plan participants or for providing other services to retirement plans. Please see "Transfer and Service Agent Agreements" in this SAI for more information.

FDC or an affiliate may also make payments to banks, broker-dealers and other service providers for distribution-related activities and/or shareholder services. If you have purchased shares of the fund through an investment professional, please speak with your investment professional to learn more about any payments his or her firm may receive from FMR, FDC and/or their affiliates, as well as fees and/or commissions the investment professional charges. You should also consult disclosures made by your investment professional at the time of purchase.

Any of the payments described in this section may represent a premium over payments made by other fund families. Investment professionals may have an added incentive to recommend a fund over others offered by competing fund families, or retirement plan sponsors may take these payments into account when deciding whether to include a fund as a plan investment option.

The following information supplements that found in the "Transfer and Service Agent Agreements" section found on page 32.

Many fund shares are owned by certain intermediaries for the benefit of their customers. Since the funds often do not maintain an account for shareholders in those instances, some or all of the recordkeeping services for these accounts may be performed by third parties. FSC or an affiliate may make payments to intermediaries for recordkeeping and other services.

Retirement plans may also hold fund shares in the name of the plan or its trustee, rather than the plan participant. In situations where FSC or an affiliate does not provide recordkeeping services to a retirement plan, plan recordkeepers, who may have affiliated financial intermediaries who sell shares of the funds, may, upon direction, be paid for providing recordkeeping services to plan participants. Payments may also be made, upon direction, for other plan expenses.

In certain situations where FSC or an affiliate provides recordkeeping services to a retirement plan, payments may be made to pay for plan expenses. The amount of such payments may be based on investments in particular Fidelity funds, or may be fixed for a given period of time. Upon direction, payments may be made to plan sponsors, or at the direction of plan sponsors, third parties, for expenses incurred in connection with the plan.

The following information supplements this Statement of Additional Information.

FUND HOLDINGS INFORMATION

Generally, each fund views holdings information as sensitive and limits the dissemination of material non-public holdings information to circumstances in accordance with Board of Trustees-approved guidelines.

1. Each fund will provide a full list of its holdings as of the end of the fund's fiscal quarter on www.fidelity.com (Research) 60 days after its fiscal quarter-end. Each money market fund's monthly holdings are also available monthly, 15 days or more after month-end by calling Fidelity at 1-800-544-8544.

2. Each fund will provide material non-public holdings information to third-parties that, i) calculate information derived from holdings either for use by FMR or by firms that supply their analyses of holdings (but not the holdings themselves) to their clients (including sponsors of retirement plans or their consultants), and ii) enter into agreements that specify that (a) holdings information will be kept confidential, (b) that no employee shall use the information for their personal benefit, (c) in which the firms certify their information security policies and procedures, and (d) which limit the nature and type of information that may be disclosed to third-parties.

3. Except as discussed below, each fund may provide to ratings and rankings organizations the same information at the same time it is filed with the SEC or one day after the information is provided on Fidelity's web site.

The information referenced in (1) above, will be available on the web site until updated for the next applicable period.

The entities that may receive the information described in (2) above are: Factset (full holdings daily, on the next day); iMoneynet (aggregate holdings weekly, one day after the end of the week); Kynex (full holdings weekly, one day after the end of the week); Vestek (full holdings, as of the end of the calendar quarter, 15 days after the calendar quarter-end); Standard & Poor's (full holdings weekly, six days after the end of the week); Moody's Investor Services (full holdings weekly, six days after the end of the week); and Wall Street Concepts (REMIC securities quarterly, 15 days after calendar quarter-end).

In addition, material non-public holdings information may be provided as part of the normal investment activities of each fund to: auditors; the custodian; broker-dealers in connection with the purchase or sale of fund securities or requests for price quotations or bids on one or more securities; counsel to the funds or the Independent Trustees; regulatory authorities; stock exchanges and other listing organizations; and parties to litigation. The entities to whom each fund voluntarily provides holdings information, either by explicit agreement or by virtue of their respective duties to each fund, are required to maintain the confidentiality of the information disclosed.

A fund may also disclose to an issuer the number of shares of the issuer (or percentage of outstanding shares) held by the fund.

As authorized by the Board of Trustees, FMR's Disclosure Policy Committee, has established and administers guidelines found by the Board to be in the best interests of shareholders concerning the dissemination of fund holdings information, and resolution of conflicts of interest in connection with such disclosure, if any. The Disclosure Policy Committee reviews and decides on each information request and, if granted, how and by whom that information will be disseminated. The Disclosure Policy Committee reports to the Board of Trustees periodically. Any modifications to the guidelines require prior Board approval.

FMR will not enter into any arrangements with third-parties from which it would derive any monetary benefit for the disclosure of material non-public holdings information. If, in the future, FMR desired to make such an arrangement, it would seek Board approval and any such arrangements would be disclosed in the funds' SAI.

There is no assurance that the funds' policies on holdings information will protect the funds from the potential misuse of holdings by individuals or firms in possession of that information.

The following information supplements that found in the Appendix section on page 34.

On July 19, 2004, a class action complaint entitled Gilliam, et al. v. Fidelity Management & Research Co., FMR Co., Inc., FMR Corp., Fidelity Distributors Corp., et al. was filed in the U.S. District Court for the District of Massachusetts alleging, among other things, that the defendants failed to disclose revenue sharing and fund portfolio brokerage practices adequately in the prospectuses of certain Fidelity funds. The complaint, which names over 200 Fidelity funds as nominal defendants, seeks unspecified damages. Four additional lawsuits making similar allegations have been filed, and other similar cases may be filed in the future. Any recovery of damages would revert to the funds. Fidelity believes these allegations are without merit and intends to defend them vigorously.
