[ X ] Yes          [   ] No

If Yes, describe the nature of any litigation or proceeding and the
position taken by the fund in that litigation:

Creditors committee in bankruptcy proceeding of Adelphia Communications
Corporation is seeking leave of the Bankruptcy Court to file a complaint
against the holders of the Adelphia and affiliates' senior secured bank
dept and those who arranged that debt, for the purpose of subordinating
that senior secured debt to the claims of the holders of those debtors'
high yield, trade and other unsecured debt. Those defendants fall into
three categories: (1) the investment banks and the agent banks that
arranged the Adelphia and Regis Family Entity credit facilities, (2) the
Co-Borrowing Lenders (those banks that made loans directly to the Adelphia
and Regis family Entity co-borrowers), and (3) the assignees of the
co-Borrowing Lenders, including primarily the mutual funds, and other
non-bank financial institutions that purchased bank loan assignments in the
secondary market. Putnam Master Income Trust has held Adelphia-related
loans and is among this third-category of defendants. The complaint alleges
that the investment banks and agent banks that arranged the credits
structured co-borrowing facilities under which both Regis Family Entities
and Adelphia businesses were entitled to borrow and were jointly and
severally liable for all amounts borrowed. The allegations, which amount to
claims of larceny, fraud, gross negligence, fraudulent transfer and other
predicates of liability, charge that those who arranged the credit knew
that the Regis Family Entities would borrow against the credit of the
Adelphia business co-borrowers and would dissipate the funds borrowed. The
complaint also alleges that the banks had access to non-public information
that should have led them to understand the accounting fraud at Adelphia.
The complaint would have the court impute the assignees (including the
Putnam funds), the knowledge and wrongful actions of the agents and lending
banks. Pursuant to a merger agreement dated November 3, 2004, Putnam Premier
Income Trust assumed all of the liabilities of Master Income Trust on
February 28, 2005, the date the merger was completed.

25. Is the fund now engaged, or intending to engage, in any business
activities other than those necessary for winding up its affairs?

If Yes, describe the nature and extent of those activities:
