<R>The following information replaces the similar information found in the "Valuing Shares" section on page 11.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 12.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

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

<R>The fund may reject for any reason, or cancel as permitted or required by law, any purchase orders, including exchanges.</R>

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

Effective April 2, 2004 the following information found under the heading "Minimums" in the "Buying and Selling Shares" section on page 14 has been changed as follows.

Purchase amounts of more than $49,999 will not be accepted for Class B shares.

<R>The following information replaces the similar information and also supplements the information found in the "Selling Shares" section beginning on page 15.</R>

<R>Trading fees are paid to the fund rather than Fidelity, and are designed to offset the brokerage commissions, market impact, and other costs associated with short-term shareholder trading.</R>

<R>The trading fee does not apply to i) reinvested dividends, ii) rollovers, transfers, and changes of account registration within the fund as long as the monies never leave the fund, iii) transfers between classes of a multiple class fund so long as the monies never leave the fund, or iv) redemptions in kind. Fidelity may assess trading fees in any of the preceding transactions if the transaction is intended to circumvent the fund's redemption fee policy. Trading fees apply to shares redeemed due to failure to maintain the account minimum, even if the balance falls below the minimum due to market action.</R>

<R>The trading fee applies to all accounts, including retirement accounts and wrap program accounts, except i) investment advisers that manage accounts that invest in the fund, including Strategic Advisers, an affiliate of FMR, may pay trading fees on behalf of their investors, ii) strategy funds, which are unitized group accounts consisting of qualified plan assets, will be treated as a single entity under the trading fee policy, and iii) intermediaries that hold shares on behalf of investors are required by the fund to track trading fees on shares purchased on or after January 3, 2005, based upon the age of the shares of each individual investor, and to remit the trading fees to the fund. The fund will refuse purchase orders from any identified intermediary who does not agree to track and remit trading fees based on the transactions of underlying investors. The Treasurer may extend the effective date for intermediaries that agree to track and remit redemption fees under an implementation plan that the intermediary commits to completing by a date approved by the fund.</R>

Trading fees apply to shares redeemed due to failure to maintain the balance minimum, even if the balance falls below the minimum due to market action.</R>

<R>The trading fee applies to all accounts, including retirement accounts and wrap program accounts, except i) investment advisers that manage accounts that invest in the fund, including Strategic Advisers, an affiliate of FMR, may pay trading fees on behalf of their investors, ii) strategy funds, which are unitized group accounts consisting of qualified plan assets, will be treated as a single entity under the trading fee policy, and iii) intermediaries that hold shares on behalf of investors are required by the fund to track trading fees on shares purchased on or after January 3, 2005, based upon the age of the shares of each individual investor, and to remit the trading fees to the fund. The fund will refuse purchase orders from any identified intermediary who does not agree to track and remit trading fees based on the transactions of underlying investors.

<R>The following information replaces the similar information found in the "Valuing Shares" section on page 10.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 11.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>AGOV-04-03November 30, 20041.756224.107</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts. </R>

<R>The following information replaces the similar information found in the "Valuing Shares" section on page 9.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts. </R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section on page 10.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

<R>The following information replaces the similar information found in the "Valuing Shares" section on page 10.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 11.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period.

FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

<R>The following information replaces the similar information found in the "Valuing Shares" section on page 7.</R>

<R>The fund's assets are valued primarily on the basis of market quotations or official closing prices. Certain short-term securities are valued on the basis of amortized cost. If market quotations or official closing prices are not readily available or do not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section on page 8.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>AMPI-04-02November 30, 20041.806138.101</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account.

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

<R>The following information replaces the similar information found in the "Valuing Shares" section on page 9.</R>

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 10.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>MOR-04-02November 30, 20041.708462.110</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer.

If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 10.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>SFI-04-04November 30, 20041.756200.109</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>

The following information replaces the similar information found in the "Valuing Shares" section on page 11.

<R>The fund's assets are valued primarily on the basis of information furnished by a pricing service or market quotations. Certain short-term securities are valued on the basis of amortized cost. If market quotations or information furnished by a pricing service is not readily available or does not accurately reflect fair value for a security or if a security's value has been materially affected by events occurring after the close of the exchange or market on which the security is principally traded, that security will be valued by another method that the Board of Trustees believes accurately reflects fair value in accordance with the Board's fair value pricing policies. For example, arbitrage opportunities may exist when trading in a portfolio security or securities is halted and does not resume before the fund calculates its NAV. These arbitrage opportunities may enable short-term traders to dilute the NAV of long-term investors. Securities trading in overseas markets present time zone arbitrage opportunities when events affecting portfolio security values occur after the close of the overseas market but prior to the close of the U.S. market. Fair value pricing may be used for high yield debt and floating rate loans when available pricing information is stale or is determined for other reasons not to accurately reflect fair value. To the extent the fund invests in other open-end funds, the fund will calculate its NAV using the NAV of the underlying funds in which it invests. The fund may invest in other Fidelity funds that use the same fair value pricing policies as the fund or in Fidelity money market funds. A security's valuation may differ depending on the method used for determining value. Fair valuation of a fund's portfolio securities can serve to reduce arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing policies will prevent dilution of the fund's NAV by short-term traders. While the fund has policies regarding excessive trading, these too may not be effective to prevent short-term NAV arbitrage trading, particularly in regard to omnibus accounts.</R>

<R>The following information supplements the information found in the "Buying and Selling Shares" section beginning on page 12.</R>

<R>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 the fund (such as brokerage commissions), disrupting portfolio management strategies, and diluting the value of the shares of long-term shareholders in cases in which fluctuations in markets are not fully priced into the fund's NAV. Accordingly, the Board of Trustees has adopted policies and procedures designed to discourage excessive or short-term trading of fund shares. However, there is the risk that the fund's policies and procedures will prove ineffective in whole or in part to detect or prevent frequent trading. The fund may alter its policies at any time without prior notice to shareholders.</R>

<R>SII-pro-04-02November 30, 20041.743368.108</R>

<R>There is no minimum holding period and shareholders can sell their shares at any time. Shareholders will ordinarily comply with the fund's policies regarding excessive trading by allowing 90 days to pass after each investment before they sell or exchange from the fund. The fund may take action if shares are held longer than 90 days if the trading is disruptive for other reasons such as unusually large trade size. The 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.</R>

<R>Excessive trading activity is measured by the number of roundtrip transactions in a shareholder's account. A roundtrip transaction occurs when a shareholder buys and then sells shares of a fund within 30 days. Shareholders are limited to two roundtrip transactions per fund within any rolling 90-day period, subject to an overall limit of four roundtrip transactions across all Fidelity funds over a rolling 12-month period. Roundtrip transactions are counted at the shareholder account level for this purpose and each class of a multiple class fund is treated separately. Transactions of $1,000 or less, systematic withdrawal and/or contribution programs, mandatory retirement distributions, and transactions initiated by a plan sponsor will not count toward the roundtrip limits. For employer-sponsored retirement plans, only participant directed exchanges will count toward the roundtrip limits.</R>

<R>Shareholders with two or more roundtrip transactions in a single fund within a rolling 90-day period will be blocked from making additional purchases or exchange purchases of the fund for 85 days. Shareholders with four or more roundtrip transactions across all Fidelity funds within any rolling 12-month period will be blocked for 85 days from additional purchases or exchange purchases across all Fidelity funds. Any roundtrip within 12 months of the expiration of a multi-fund block will initiate another multi-fund block for an 85-day period. For repeat offenders, FMR may, but does not have the obligation to, impose long-term or permanent blocks on purchase or exchange purchase transactions in any account under the shareholder's common control at any time, other than a participant's account held through an employer-sponsored retirement plan. Employer-sponsored retirement plan participants whose activity triggers a purchase or exchange block will be permitted a minimum of one trade every calendar quarter. In the event of a block, employer and participant contributions and loan repayments by the participant may still be invested in the fund. FMR reserves the right, but does not have the obligation 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.</R>

<R>Qualified wrap programs will be monitored by matching the adviser's orders for purchase, exchange, or sale transactions in fund shares to determine if the adviser's orders comply with the fund's frequent trading policies. Excessive trading by an adviser will lead to fund blocks and the wrap program will cease to be a qualified wrap program. Additions to and withdrawals from a qualified wrap program by the adviser's client will not be matched with transactions initiated by the adviser, but client initiated transactions are subject to the fund's policies on frequent trading and individual clients may be subject to restrictions due to their frequent trading in a wrap account. Commencing no later than March 31, 2005, wrap account client purchases and sale transactions will be monitored under the fund's monitoring policy as though the wrap clients were fund shareholders. A qualified wrap program is: i) a program whose adviser certifies that it has investment discretion over $100 million or more in client assets invested in mutual funds at the time of the certification, ii) a program in which the adviser directs transactions in the accounts participating in the program in concert with changes in a model portfolio, and iii) managed by an adviser who agrees to give FMR sufficient information to permit FMR to identify the individual accounts in the wrap program.</R>

<R>The fund's excessive trade monitoring policy described above does not apply to transactions initiated by the trustee or adviser to a donor-advised charitable gift fund, qualified fund-of-funds or other strategy funds, or omnibus accounts. Trustees or advisers of donor-advised charitable gift funds must certify that they either work from an asset allocation model or direct transactions in the donor accounts in concert with changes in a model portfolio and that donors are limited in their ability to influence investments by the trust. A qualified fund-of-fund is a mutual fund or other strategy fund consisting of qualified plan assets that either applies the fund's policies on frequent trading to shareholders at the top-fund level, or demonstrates that it has policies designed to control frequent trading and that they are reasonably likely to be effective as determined by the fund's Treasurer. The adviser to the top-fund level must also demonstrate to the fund's Treasurer that its investment strategy will not lead to excessive trading. Strategy funds must commence monitoring for excessive trading no later than March 31, 2005. Omnibus accounts are maintained by intermediaries acting on behalf of multiple investors whose individual trades are not ordinarily disclosed to the fund. Short-term trading by these investors is likely to go undetected by the fund and may increase costs and disrupt portfolio management. The fund will monitor aggregate trading in qualified fund-of-funds and known omnibus accounts to attempt to identify disruptive trades, focusing on transactions in excess of $250,000. There is no assurance that these policies will be effective, or will successfully detect or deter market timing.</R>

<R>The fund's Treasurer is authorized to suspend the fund's policies during periods of severe market turbulence or national emergency and to grant exemptions from the policy. There is no assurance that the fund's Treasurer will exercise this authority or that by exercising this authority the fund will be protected from the risks associated with frequent trading. The actions of the Treasurer are periodically reviewed with the Board of Trustees.</R>
