NOTES

(a) Percentages indicated are based on net assets of $295,168,996.

(RAT) The Moody's or Standard & Poor's ratings indicated are believed to be the most recent ratings available at February 28, 2007 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 February 28, 2007. Securities rated by Putnam are indicated by "/P." Securities rated by Fitch are indicated by "/F." Security ratings are defined in the Statement of Additional Information.

(b) The aggregate identified cost on a tax basis is $277,458,728, resulting in gross unrealized appreciation and depreciation of $16,058,945 and $141,502, respectively, or net unrealized appreciation of $15,917,443.

The rates shown on VRDN are the current interest rates at February 28, 2007.

The dates shown on debt obligations are the original maturity dates.

The fund had the following sector concentrations greater than 10% at February 28, 2007 (as a percentage of net assets):
Health care	22.2%
Utilities and power	19.9
Education	18.9
The fund had the following insurance concentrations greater than 10% at February 28, 2007 (as a percentage of net assets):
FSA	17.9%
FGIC	12.6
MBIA	11.5

Security valuation Tax-exempt bonds and notes are generally valued 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. Certain investments are also 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.

Interest rate swap contracts The fund may enter into interest rate swap contracts, which are arrangements between two parties to exchange cash flows based on a notional principal amount, to manage the fund’s exposure to interest rates. Interest rate swap contracts are marked-to-market daily based upon quotations from an independent pricing service or market makers and the change, if any, is recorded as unrealized gain or loss. Payments received or made are recorded as realized gains or loss. Certain interest rate swap contracts may include extended effective dates. Income related to these swap contracts is accrued based on the terms of the contract. The fund could be exposed to credit or market risk due to unfavorable changes in the fluctuation of interest rates or if the counterparty defaults on its obligation to perform. Risk of loss may exceed amounts recognized on the statement of assets and liabilities. Interest rate swap contracts outstanding at period end, if any, are listed after the fund’s portfolio.

For additional information regarding the fund please see the fund's most recent annual or semiannual shareholder report filed on the Securities and Exchange Commission's Web site, www.sec.gov, or visit Putnam's Individual Investor Web site at www.putnaminvestments.com

Item 2. Controls and Procedures:

(a) The registrant's principal executive officer and principal financial officer have concluded, based on their evaluation of the effectiveness of the design and operation of the registrant's disclosure controls and procedures as of a date within 90 days of the filing date of this report, that the design and operation of such procedures are generally effective to provide reasonable assurance that information required to be disclosed by the registrant in this report is recorded, processed, summarized and reported within the time periods specified in the Commission's rules and forms.

(b) Changes in internal control over financial reporting: Effective January 1, 2007, the fund retained State Street Bank and Trust Company ("State Street") as its custodian. Putnam Fiduciary Trust Company, the fund's previous custodian, is managing the transfer of the fund's assets to State Street. This transfer is expected to be completed for all Putnam funds during the first half of 2007, with PFTC remaining as custodian with respect to fund assets until the assets are transferred. Also effective January 1, 2007, the fund's investment manager, Putnam Investment Management, LLC entered into a Master Sub-Accounting Services Agreement with State Street, under which the investment manager has delegated to State Street responsibility for providing certain administrative, pricing, and bookkeeping services for the fund.

Item 3. Exhibits:
