Investments in Class T shares of $250,000 or more may, upon redemption less than one year after purchase, for any reason, including failure to maintain the account minimum, be assessed a CDSC of 0.25%. The actual CDSC you pay may be higher or lower than that calculated using this percentage due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

When exchanging Class T shares of one fund for Class T shares of another Fidelity fund that offers Advisor classes of shares or Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund, your Class T shares retain the CDSC schedule in effect when they were originally bought.

On or about February 18, 2011, the following replaces similar information found under the "Fund Distribution" section beginning on page 31.

The CDSC, if any, for Class A and Class T shares will be calculated based on the lesser of the cost of each class's shares, as applicable, at the initial date of purchase or the value of those shares, as applicable, at redemption, not including any reinvested dividends or capital gains. Class A and Class T shares acquired through reinvestment of dividends or capital gain distributions will not be subject to a CDSC. In determining the applicability and rate of any CDSC at redemption, shares representing reinvested dividends and capital gains will be redeemed first, followed by those shares that have been held for the longest period of time, provided that Class A shares not subject to a CDSC will be redeemed before Class A shares subject to a CDSC, even if the Class A shares subject to a CDSC have been held longer.

Finder's Fees. Finder's fees may be paid to investment professionals who sell Class A and Class T shares in purchase amounts of $250,000 or more. For Class A share purchases, investment professionals may be compensated monthly, up to 18 months, with a finder's fee at an annual rate of 0.40% of such Class A share's average net assets throughout the month (up to 0.60% in the aggregate). Finder's fee payments will cease upon the earlier of a redemption (including an exchange, except for an exchange to another fund with the same finder's fee rate) of such Class A shares or the expiration of 18 months. For Class T share purchases, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.25% of the purchase amount.

Investment professionals may be eligible for a finder's fee on the following purchases of Class A and Class T shares made through broker-dealers and banks: a trade that brings the value of the accumulated account(s) of an investor, including a 403(b) program or an employee benefit plan (except a SEP or SARSEP plan or a plan covering self-employed individuals and their employees (formerly a Keogh/H.R. 10 plan)), over $250,000; a trade for an investor with an accumulated account value of $250,000 or more; and an incremental trade toward an investor's Letter. Accumulated account value for purposes of finder's fees eligibility is determined the same as it is for Rights of Accumulation. Daily Money Class shares of Treasury Fund, Prime Fund, or Tax-Exempt Fund are not counted for this purpose unless acquired by exchange from any Fidelity fund that offers Advisor classes of shares. For information, see "Combined Purchase, Rights of Accumulation, and Letter of Intent Programs" above.

Finder's fees are not paid in connection with purchases of Class A or Class T shares by insurance company separate accounts, the Fidelity Investments Charitable Gift Fund, or managed account programs that charge an asset-based fee, or purchases of Class A or Class T shares made with the proceeds from the redemption of shares of any Fidelity fund or any retirement plan recordkept at Fidelity.

Investment professionals should contact Fidelity in advance to determine if they qualify to receive a finder's fee.

Finder's Fees (Fidelity Advisor 401(k) Retirement Plans only). Finder's fees will be paid in connection with shares recordkept in a Fidelity Advisor 401(k) Retirement Plan only at the time of the initial conversion of assets. For Class A conversions to a Fidelity Advisor 401(k) Retirement Plan, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.75% of the purchase amount for purchases of $1 million but less than $4 million, 0.50% of the purchase amount for purchases of $4 million but less than $25 million, and 0.25% of the purchase amount for purchases of $25 million or more. When a finder's fee is paid, the investment professional concession as a percentage of the offering price is paid at a blended rate. Such Class A purchases may be subject, upon redemption, to a CDSC of 0.75% if redeemed less than 18 months after purchase. For Class T conversions of $1 million or more to a Fidelity Advisor 401(k) Retirement Plan, investment professionals may be compensated at the time of purchase with a finder's fee at the rate of 0.25% of the purchase amount. Such Class T purchases may be subject, upon redemption, to a CDSC of 0.25% if redeemed less than one year after purchase. Such Class A and Class T purchases may be subject to a CDSC upon redemption for any reason, including failure to maintain the account minimum, and the actual CDSC you pay may be higher or lower than the stated percentage due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investment professionals should contact Fidelity for more information.
