Effective immediately, similar disclosure in the section Fund Summary--Purchase and sale of fund shares is deleted in its entirety and replaced with the following:

You can sell your shares back to the fund or exchange them for shares of another Putnam fund any day the New York Stock Exchange (NYSE) and the Federal Reserve Bank of New York (FRBNY) are both open. Shares may be sold or exchanged by mail, by phone, or online at putnam.com. Some restrictions may apply.

Effective immediately, similar disclosure in the section How does the fund price its shares? is deleted in its entirety and replaced with the following:

Shares are only valued as of the scheduled close of regular trading on the NYSE each day the NYSE and FRBNY are both open.

Effective immediately, similar disclosure in the sub-section Purchasing additional shares in the section How do I buy fund shares? is deleted in its entirety and replaced with the following:

• By wire transfer. You may buy fund shares by bank wire transfer of same-day funds. Please call Putnam Investor Services at 1-800-225-1581 for wiring instructions. Any commercial bank can transfer same-day funds by wire. The fund will normally accept wired funds for investment on the day received if they are received by the fund’s designated bank before the close of regular trading on the NYSE on days the NYSE and FRBNY are both open. Your bank may charge you for wiring same-day funds. Although the fund’s designated bank does not currently charge you for receiving same-day funds, it reserves the right to charge for this service. You cannot buy shares for employer-sponsored retirement plans by wire transfer.

Effective immediately, similar disclosure in the sub-section Which class of shares is best for me? in the section How do I buy fund shares? is deleted in its entirety and replaced with the following:

• General (all classes). Because the fund seeks to be fully invested at all times, the fund only sells shares to you when it receives “same-day funds,” which are monies that are credited to the fund’s designated bank account at the Federal Reserve Bank of Boston. If the fund receives same-day funds before the close of trading on the NYSE on days that the NYSE and FRBNY are both open, it will accept the order to buy shares that day.

You can sell your shares back to the fund or exchange them for shares of another Putnam fund any day the NYSE and FRBNY are both open, either through your financial representative or directly to the fund.

If you redeem your shares shortly after purchasing them, your redemption payment for the shares may be delayed until the fund collects the purchase price of the shares, which may be up to 7 calendar days after the purchase date.

Effective immediately, similar disclosure in the section How do I sell or exchange fund shares? is deleted in its entirety and replaced with the following:
