<R>The following information replaces similar information found in the "Distribution Services" section on page 28.</R>

<R>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.</R>

<R>The Trustees have approved a Distribution and Service Plan 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.</R>

<R>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 U.S. Government and Cash Reserves shares.</R>

<R>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.</R>

<R>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.</R>

<R>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.</R>

<R>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 a 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.</R>

<R>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.</R>

<R>The following information supplements that found in the "Transfer and Service Agent Agreements" section on page 29.</R>

<R>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.</R>

<R>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.</R>

<R>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. </R>
