^A The actual sales charge you pay may be higher or lower than those calculated using these percentages due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investments in Class A shares of $1 million or more may, upon redemption for any reason, including failure to maintain the account minimum, be assessed a CDSC based on the following schedule:

From Date of Purchase	Contingent Deferred Sales ChargeA
Less than 1 year	0.75%
1 year to less than 2 years	0.50%
2 years or more	0.00%

^A The actual CDSC you pay may be higher or lower than those calculated using these percentages 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 A shares of one fund for Class A 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 A shares retain the CDSC schedule in effect when they were originally bought.

Sales Charges and Concessions - Class T

^A The actual sales charge you pay may be higher or lower than those calculated using these percentages due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

Investments in Class T shares of $1 million 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.

The CDSC for Class A, Class T, Class B, and Class C 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, Class T, Class B, and Class C 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.
