There is still time to vote on the issues that affect your fund!
Dear Shareholder:
In September, we mailed you a proxy statement requesting your vote on a proposed merger ofPutnam Investment Grade Municipal TrustandPutnam Municipal Bond Fundinto Putnam Municipal Opportunities Trust, another fund managed by Putnam. The Trustees unanimously recommend approval of this merger proposal. Our records show that we have not yet received your completed ballot.
We have included another copy of the ballot and a postage-paid return envelope for your convenience. Your vote on this matter is important — and action on your part saves your fund money. If you have already voted, please ignore this letter, and thank you for your vote. If you have any questions about the proposal, please call 1-800-780-7316 or consult your financial representative.
Sincerely,
John A. Hill
Chairman of the Trustees
