Notes to the fund's portfolio
Unless noted otherwise, the notes to the fund's portfolio are for the close of the fund's reporting period, which ran from May 1, 2013 through July 31, 2013 (the reporting period). Within the following notes to the portfolio, references to “ASC 820” represent Accounting Standards Codification 820 Fair Value Measurements and Disclosures, references to “Putnam Management” represent Putnam Investment Management, LLC, the fund's manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC and references to “OTC”, if any, represent over-the-counter.
(a) Percentages indicated are based on net assets of $515,691,476.
(RAT) The Moody's, Standard & Poor's or Fitch ratings indicated are believed to be the most recent ratings available at the close of the reporting period 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 the close of the reporting period. Securities rated by Putnam are indicated by “/P.” Securities rated by Fitch are indicated by “/F.” The rating of an insured security represents what is believed to be the most recent rating of the insurer's claims-paying ability available at the close of the reporting period, if higher than the rating of the direct issuer of the bond, and does not reflect any subsequent changes.
(b) The aggregate identified cost on a tax basis is $714,691,869, resulting in gross unrealized appreciation and depreciation of $34,585,937 and $16,956,626, respectively, or net unrealized appreciation of $17,629,311.
(NON) Non-income-producing security.
(STP) The interest rate and date shown parenthetically represent the new interest rate to be paid and the date the fund will begin accruing interest at this rate.
(SEGSF) This security, in part or in entirety, was pledged and segregated with the custodian for collateral on certain derivative contracts at the close of the reporting period.
(FWC) Forward commitment, in part or in entirety.
(P) Security was pledged, or purchased with cash that was pledged, to the fund for collateral on certain derivatives contracts. The rate quoted in the security description is the annualized 7-day yield of the fund at the close of the reporting period.
(T) Underlying security in a tender option bond transaction. The security has been segregated as collateral for financing transactions.
At the close of the reporting period, the fund maintained liquid assets totaling $47,477,234 to cover tender option bonds and certain derivatives contracts.
144A after the name of an issuer represents securities exempt from registration under Rule 144A under the Securities Act of 1933, as amended. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers.
The rates shown on Mandatory Put Bonds are the current interest rates at the close of the reporting period.
The dates shown parenthetically on Mandatory Put Bonds represent the next mandatory put dates.
The dates shown parenthetically on prerefunded bonds represent the next prerefunding dates.
The dates shown on debt obligations are the original maturity dates.
The fund had the following sector concentrations greater than 10% at the close of the reporting period (as a percentage of net assets):
Utilities 24.6%
Health care 23.9
Transportation 21.8
State government 13.7
Education 12.6
Local government 12.4
Tax bonds 11.7
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. These securities will generally be categorized as Level 2.
Certain investments, including certain restricted and illiquid securities and derivatives are also valued at fair value following procedures approved by the Trustees. Such valuations and procedures are reviewed periodically by the Trustees. These valuations consider such factors as significant market or specific security events such as interest rate or credit quality changes, various relationships with other securities, discount rates, U.S. Treasury, U.S. swap and credit yields, index levels, convexity exposures and recovery rates. These securities are classified as Level 2 or as Level 3 depending on the priority of the significant inputs. 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 in a current sale and does not reflect an actual market price, which may be different by a material amount.
Total return swap contracts: The fund entered into OTC total return swap contracts, which are arrangements to exchange a market linked return for a periodic payment, both based on a notional principal amount, to manage interest rate risk.
To the extent that the total return of the security, index or other financial measure underlying the transaction exceeds or falls short of the offsetting interest rate obligation, the fund will receive a payment from or make a payment to the counterparty. OTC total return 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 an unrealized gain or loss. Payments received or made are recorded as realized gains or losses. Certain OTC total return swap contracts may include extended effective dates. Payments related to these swap contracts are 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 in the price of the underlying security or index, the possibility that there is no liquid market for these agreements or that the counterparty may default on its obligation to perform. The fund’s maximum risk of loss from counterparty risk is the fair value of the contract. This risk may be mitigated by having a master netting arrangement between the fund and the counterparty.
For the fund's average notional amount on OTC total return swap contracts, see the appropriate table at the end of these footnotes.
Master agreements: The fund is a party to ISDA (International Swaps and Derivatives Association, Inc.) Master Agreements (Master Agreements) with certain counterparties that govern over the counter derivative and foreign exchange contracts entered into from time to time. The Master Agreements may contain provisions regarding, among other things, the parties’ general obligations, representations, agreements, collateral requirements, events of default and early termination. With respect to certain counterparties, in accordance with the terms of the Master Agreements, collateral posted to the fund is held in a segregated account by the fund’s custodian and with respect to those amounts which can be sold or repledged, are presented in the fund’s portfolio.
Collateral pledged by the fund is segregated by the fund’s custodian and identified in the fund’s portfolio. Collateral can be in the form of cash or debt securities issued by the U.S. Government or related agencies or other securities as agreed to by the fund and the applicable counterparty. Collateral requirements are determined based on the fund’s net position with each counterparty.
Termination events applicable to the fund may occur upon a decline in the fund’s net assets below a specified threshold over a certain period of time. Termination events applicable to counterparties may occur upon a decline in the counterparty’s long-term and short-term credit ratings below a specified level. In each case, upon occurrence, the other party may elect to terminate early and cause settlement of all derivative and foreign exchange contracts outstanding, including the payment of any losses and costs resulting from such early termination, as reasonably determined by the terminating party. Any decision by one or more of the fund’s counterparties to elect early termination could impact the fund's future derivative activity.
At the close of the reporting period, the fund had a net liability position of $1,126,171 on open derivative contracts subject to the Master Agreements. Collateral posted by the fund for these agreements totaled $1,158,627.
Tender option bond transactions: The fund may participate in transactions whereby a fixed-rate bond is transferred to a tender option bond trust (TOB trust) sponsored by a broker. The TOB trust funds the purchase of the fixed rate bonds by issuing floating-rate bonds issued to third parties and allowing the fund to retain the residual interest in the TOB trust’s assets and cash flows, which are in the form of inverse floating rate bonds. The inverse floating rate bonds held by the fund give the fund the right to (1) cause the holders of the floating rate bonds to tender their notes at par, and (2) to have the fixed-rate bond held by the TOB trust transferred to the fund, causing the TOB trust to collapse. The fund accounts for the transfer of the fixed-rate bond to the TOB trust as a secured borrowing by including the fixed-rate bond in The fund’s portfolio and including the floating rate bond as a liability in the Statement of assets and liabilities. At the close of the reporting period, the fund’s investments with a value of $88,031,821 were held by the TOB trust and served as collateral for $41,680,759 in floating-rate bonds outstanding. During the reporting period, the fund incurred interest expense of $9,837 for these investments based on an average interest rate of 0.11%.













ASC 820 establishes a three-level hierarchy for disclosure of fair value measurements. The valuation hierarchy is based upon the transparency of inputs to the valuation of the fund’s investments. The three levels are defined as follows:
Level 1: Valuations based on quoted prices for identical securities in active markets.
Level 2: Valuations based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly.
Level 3: Valuations based on inputs that are unobservable and significant to the fair value measurement.
The following is a summary of the inputs used to value the fund’s net assets as of the close of the reporting period:

Municipal bonds and notes $— $732,031,180 $—
