OF SPECIAL INTEREST MERGER WITH PUTNAM MASTER INCOME TRUST PROPOSED The fund's Trustees have approved in principle the merger of Putnam Master Income Trust into your fund.

Completion of the merger is subject to a number of conditions, including final approval by each fund's Trustees and approval by shareholders of each fund at a joint shareholder meeting expected to be held within the coming months. This report is not an offer to sell, nor a solicitation of an offer to buy, shares of any fund, nor is it a solicitation of a proxy.
