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 November 1, 2010 through July 31, 2011 (the reporting period).
(a) Percentages indicated are based on net assets of $739,740,251.
(b) The aggregate identified cost on a tax basis is $687,744,791, resulting in gross unrealized appreciation and depreciation of $75,996,395 and $25,423,673, respectively, or net unrealized appreciation of $50,572,722.
(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.
(d) The fund may lend securities, through its agent, to qualified borrowers in order to earn additional income. The loans are collateralized by cash in an amount at least equal to the market value of the securities loaned. The market value of securities loaned is determined daily and any additional required collateral is allocated to the fund on the next business day. The risk of borrower default will be borne by the fund’s agent; the fund will bear the risk of loss with respect to the investment of the cash collateral. At the close of the reporting period, the value of securities loaned amounted to $3,465,280. The fund received cash collateral of $3,530,800 which is invested in Putnam Cash Collateral Pool, LLC, a limited liability company managed by an affiliate of Putnam Investment Management, LLC (Putnam Management), the fund's manager, an indirect wholly-owned subsidiary of Putnam Investments, LLC. Investments in Putnam Cash Collateral Pool, LLC are valued at its closing net asset value each business day. There are no management fees charged by Putnam Cash Collateral Pool, LLC. The rate quoted in the security description is the annualized 7-day yield at the close fo the reporting period.
(e) The fund invested in Putnam Money Market Liquidity Fund, an open-end management investment company managed by Putnam Management. Investments in Putnam Money Market Liquidity Fund are valued at its closing net asset value each business day. Income distributions earned by the fund are recorded as interest income and totaled $10,473 for the reporting period. During the reporting period, cost of purchases and proceeds of sales of investments in Putnam Money Market Liquidity Fund aggregated $228,625,600 and $216,952,335, respectively. Management fees charged to Putnam Money Market Liquidity Fund have been waived by Putnam Management. The rate quoted in the security description is the annualized 7-day yield of the fund at the close of the reporting period.
(F) Is valued at fair value following procedures approved by the Trustees. Securities may be classified as Level 2 or Level 3 for Accounting Standards Codification ASC 820 Fair Value Measurements and Disclosures (ASC 820) based on the securities' valuation inputs.
(R) Real Estate Investment Trust.
(S) Security on loan, in part or in entirety, at the close of the reporting period.
Debt obligations are considered secured unless otherwise indicated.
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 FRB and FRN are the current interest rates at the close of the reporting period.
The dates shown on debt obligations are the original maturity dates.
Security valuation: Investments for which market quotations are readily available are valued at the last reported sales price on their principal exchange, or official closing price for certain markets, and are classified as Level 1 securities. If no sales are reported— as in the case of some securities traded over-the-counter— a security is valued at its last reported bid price and is generally categorized as a Level 2 security.
Market quotations are not considered to be readily available for certain debt obligations and other investments; such investments are valued on the basis of valuations furnished by an independent pricing service approved by the Trustees or dealers selected by Putnam Management. Such services or dealers determine valuations for normal institutional-size trading units of such securities using methods based on market transactions for comparable securities and various relationships, generally recognized by institutional traders, between securities (which considers such factors as security prices, yields, maturities and ratings). These securities will generally be categorized as Level 2.
Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange and therefore the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. Accordingly, on certain days, the fund will fair value foreign equity securities taking into account multiple factors including movements in the U.S. securities markets, currency valuations and comparisons to the valuation of American Depository Receipts, exchange-traded funds and futures contracts. These securities, which will generally represent a transfer from a Level 1 to a Level 2 security, will be classified as Level 2. The number of days on which fair value prices will be used will depend on market activity and it is possible that fair value prices will be used by the fund to a significant extent. Securities quoted in foreign currencies, if any, are translated into U.S. dollars at the current exchange rate.
To the extent a pricing service or dealer is unable to value a security or provides a valuation that Putnam Management does not believe accurately reflects the security's fair value, the security will be valued at fair value by Putnam Management. Certain investments, including certain restricted and illiquid securities and derivatives, are also valued at fair value following procedures approved 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.
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 in a current sale and does not reflect an actual market price, which may be different by a material amount.













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:
