NOTES

(a) Percentages indicated are based on net assets of $37,542,548.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at July 31, 2006 for the securities listed. Ratings are generally ascribed to securities at the time of issuance. While the agencies may from time to time revise such ratings, they undertake no obligation to do so, and the ratings do not necessarily represent what the agencies would ascribe to these securities at July 31, 2006. Securities rated by Putnam are indicated by "/P". Securities rated by Fitch are indicated by "/F".

(b) The aggregate identified cost on a tax basis is $45,999,858, resulting in gross unrealized appreciation and depreciation of $1,338,560 and $104,549, respectively, or net unrealized appreciation of $1,234,011.

(SEG) A portion of this security was pledged and segregated with the custodian to cover margin requirements for futures contracts at July 31, 2006.

At July 31, 2006, liquid assets totaling $1,060,312 have been designated as collateral for open futures contracts.

The rates shown on VRDN and Mandatory Put Bonds, are the current interest rates at July 31, 2006.

The dates shown on Mandatory Put Bonds are the next mandatory put dates.

The fund had the following industry group concentrations greater than 10% at July 31, 2006 (as a percentage of net assets):

Transportation  21.2% 
Utilities  20.8 
Education  16.5 
Health care  11.3 

The fund had the following insurance concentrations greater than 10% at July 31, 2006 (as a percentage of net assets):

MBIA  20.4%

Security valuation Tax-exempt bonds and notes are valued at fair value on the basis of valuations provided by an independent pricing service, approved by the Trustees. Such services use information with respect to transactions in bonds, quotations from bond dealers, market transactions in comparable securities and various relationships between securities in determining value. Other investments are valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. The fair value of securities is generally determined as the amount that the fund could reasonably expect to realize from an orderly disposition of such securities over a reasonable period of time. By its nature, a fair value price is a good faith estimate of the value of a security at a given point in time and does not reflect an actual market price, which may be different by a material amount.


Futures and options contracts The fund may use futures and options contracts to hedge against changes in the values of securities the fund owns or expects to purchase, or for other investment purposes. The fund may also write options on swaps or securities it owns or in which it may invest to increase its current returns.

The potential risk to the fund is that the change in value of futures and options contracts may not correspond to the change in value of the hedged instruments. In addition, losses may arise from changes in the value of the underlying instruments, if there is an illiquid secondary market for the contracts, or if the counterparty to the contract is unable to perform. Risks may exceed amounts recognized on the statement of assets and liabilities. When the contract is closed, the fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Realized gains and losses on purchased options are included in realized gains and losses on investment securities. If a written call option is exercised, the premium originally received is recorded as an addition to sales proceeds. If a written put option is exercised, the premium originally received is recorded as a reduction to the cost of investments.

Futures contracts are valued at the quoted daily settlement prices established by the exchange on which they trade. The fund and the broker agree to exchange an amount of cash equal to the daily fluctuation in the value of the futures contract. Such receipts or payments are known as “variation margin.” Exchange traded options are valued at the last sale price or, if no sales are reported, the last bid price for purchased options and the last ask price for written options. Options traded over-the-counter are valued using prices supplied by dealers. Futures and written option contracts outstanding at period end, if any, are listed after the fund’s portfolio.
