STATEMENT OF ADDITIONAL INFORMATION

The following information supplements the information found in the "Investment Policies and Limitations" section beginning on page 2.

Swap Agreements can be individually negotiated and structured to include exposure to a variety of different types of investments or market factors. Depending on their structure, swap agreements may increase or decrease a fund's exposure to long- or short-term interest rates, mortgage securities, corporate borrowing rates, or other factors such as security prices or inflation rates. Swap agreements can take many different forms and are known by a variety of names.

In a typical cap or floor agreement, one party agrees to make payments only under specified circumstances, usually in return for payment of a fee by the other party. For example, the buyer of an interest rate cap obtains the right to receive payments to the extent that a specified interest rate exceeds an agreed-upon level, while the seller of an interest rate floor is obligated to make payments to the extent that a specified interest rate falls below an agreed-upon level. An interest rate collar combines elements of buying a cap and selling a floor.

Swap agreements will tend to shift a fund's investment exposure from one type of investment to another. For example, if the fund agreed to pay fixed rates in exchange for floating rates while holding fixed-rate bonds, the swap would tend to decrease the fund's exposure to long-term interest rates. Caps and floors have an effect similar to buying or writing options. Depending on how they are used, swap agreements may increase or decrease the overall volatility of a fund's investments and its share price and yield.

The most significant factor in the performance of swap agreements is the change in the specific interest rate, or other factors that determine the amounts of payments due to and from a fund. If a swap agreement calls for payments by the fund, the fund must be prepared to make such payments when due. In addition, if the counterparty's creditworthiness declined, the value of a swap agreement would be likely to decline, potentially resulting in losses. A fund may be able to eliminate its exposure under a swap agreement either by assignment or other disposition, or by entering into an offsetting swap agreement with the same party or a similarly creditworthy party.

<R>The following information replaces similar information found in the "Distributions and Taxes" section on page 37.</R>

<R>Generally, each fund purchases municipal securities whose interest, in the opinion of the issuer's bond counsel, is free from federal income tax. FMR does not guarantee that this opinion is correct and there is no assurance that the IRS will agree with bond counsel's opinion. Issuers or other parties generally enter into covenants requiring continuing compliance with federal tax requirements to preserve the tax-free status of interest payments over the life of the security. If at any time the covenants are not complied with, or if the IRS otherwise determines that the issuer did not comply with relevant tax requirements, interest payments from a security could become federally taxable retroactive to the date the security was issued. For certain types of structured securities, the tax status of the pass-through of tax-free income may also be based on the federal and state tax treatment of the structure. </R>
