Statement of Additional Information Supplement  Dated July 16, 2010 

For all Putnam retail funds and Putnam Variable Trust:

The following paragraph is added at the end of the section MISCELLANEOUS INVESTMENTS, INVESTMENT PRACTICES AND RISKS — Borrowing and Other Forms of Leverage:

Each Putnam fund (other than Putnam RetirementReady^® Funds, Putnam Global Sector Fund and Putnam Money Market Liquidity Fund) participates in committed and uncommitted lines of credit with State Street Bank and Trust Company. These lines of credit are intended to provide a temporary source of cash in extraordinary or emergency circumstances, such as unexpected shareholder redemption requests. The fund may pay a commitment or other fee to maintain a line of credit, in addition to the stated interest rate.

The following paragraphs are added to the section MISCELLANEOUS INVESTMENTS, INVESTMENT PRACTICES AND RISKS:

Interfund Borrowing and Lending

To satisfy redemption requests or to cover unanticipated cash shortfalls, the fund has entered into a Master Interfund Lending Agreement by and among each Putnam fund and Putnam Management (the “Interfund Lending Agreement”) under which the fund would lend or borrow money for temporary purposes directly to or from another Putnam fund (an “Interfund Loan”), subject to meeting the conditions of an SEC exemptive order granted to the fund permitting such Interfund Loans. All Interfund Loans would consist only of uninvested cash reserves that the lending fund otherwise would invest in short-term repurchase agreements or other short-term instruments. At this time, Putnam Money Market Liquidity Fund is the only Putnam fund expected to make its uninvested cash reserves available for Interfund Loans.

If the fund has outstanding borrowings, any Interfund Loans to the fund (a) would be at an interest rate equal to or lower than that of any outstanding bank loan, (b) would be secured at least on an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding bank loan that requires collateral, and (c) would have a maturity no longer than any outstanding bank loan (and in any event not over seven days). In addition, if an event of default were to occur under any agreement evidencing an outstanding bank loan to the fund, the event of default would automatically (without need for action or notice by the lending fund) constitute an immediate event of default under the Interfund Lending Agreement entitling the lending fund to call the Interfund Loan (and exercise all rights with respect to any collateral) and such a call would be deemed made if the lending bank exercises its right to call its loan under its agreement with the borrowing fund.

The fund may make an unsecured borrowing under the Interfund Lending Agreement if its outstanding borrowings from all sources immediately after the interfund borrowing total 10% or less of its total assets; provided, that if the fund has a secured loan outstanding from any other

lender, including but not limited to another Putnam fund, the fund’s Interfund Loan would be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding loan secured by collateral. If the fund’s total outstanding borrowings immediately after an interfund borrowing would be greater than 10% of its total assets, the fund may borrow through the credit facility on a secured basis only. All secured Interfund Loans would be secured by the pledge of segregated collateral with a market value equal to at least 102% of the outstanding principal value of the Interfund Loan. The fund may not borrow from any source if its total outstanding borrowings immediately after the borrowing would exceed the limits imposed by Section 18 of the 1940 Act or the fund’s fundamental investment restrictions.

The fund may not lend to another Putnam fund under the Interfund Lending Agreement if the Interfund Loan would cause its aggregate outstanding Interfund Loans to exceed 15% of the fund’s current net assets at the time of the Interfund Loan. The fund’s Interfund Loans to any one fund may not exceed 5% of the lending fund’s net assets. The duration of Interfund Loans would be limited to the time required to receive payment for securities sold, but in no event may the duration exceed seven days. Interfund Loans effected within seven days of each other would be treated as separate loan transactions for purposes of this condition. Each Interfund Loan may be called on one business day’s notice by a lending fund and may be repaid on any day by a borrowing fund.

The limitations detailed above and the other conditions of the SEC exemptive order permitting interfund lending are designed to minimize the risks associated with interfund lending for both the lending fund and the borrowing fund. However, no borrowing or lending activity is without risk. If the fund borrows money from another fund, there is a risk that the Interfund Loan could be called on one day’s notice or not renewed, in which case the fund may have to borrow from a bank at higher rates if an Interfund Loan were not available from another fund. A delay in repayment to a lending fund could result in a lost opportunity or additional lending costs, and interfund loans are subject to the risk that the borrowing fund could be unable to repay the loan when due.

For all Putnam retail funds:

The section Exceptions to application of short-term trading fee in HOW TO BUY SHARES—Sales Charges and Other Share Class Features—Retail Investors—is restated to read as follows:

Exceptions to application of short-term trading fee. In addition to the exceptions noted in the fund’s prospectus, the short-term trading fee will not apply to redemptions from certain wrap accounts, or to automatic rebalancing arrangements, with respect to which Putnam Retail Management and a dealer have entered into an agreement and also will not be imposed in cases of shareholder death or post-purchase disability or other circumstances in which a CDSC would be waived as stated above under “Other exceptions to application of CDSC.”
