<R>FMR normally invests at least 80% of the fund's assets in debt securities of all types and repurchase agreements for those securities. FMR allocates the fund's assets across investment-grade, high yield, and emerging market debt securities. FMR may invest up to 20% of the fund's assets in high yield and emerging market debt securities.</R>

The following information supplements that found in the "Buying and Selling Shares" section beginning on page 13.

The dollar amount of the sales charge for Class A or Class T is the difference between the offering price of the shares purchased and the NAV of those shares. Since the offering price per share is calculated to the nearest cent using standard rounding criteria, the percentage sales charge you actually pay may be higher or lower than the sales charge percentages shown in this prospectus due to rounding. The impact of rounding may vary with the amount of your investment and the size of the class's NAV.

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

Sales Charges and Concessions - Class T

Up to $49,999	3.50%	3.63%	3.00%

^BAfter a maximum of seven years, Class B shares will convert automatically to Class A shares of the fund.

Class C shares may, upon redemption less than one year after purchase, for any reason, including failure to maintain the account minimum, be assessed a CDSC of 1.00%. The actual CDSC you pay may be higher or lower than that calculated using this percentage due to rounding.

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.
