Item 9.  Regulation FD Disclosure.

On June 9, 2004, MMC reached a final settlement of the previously disclosed
arbitration proceeding with Lawrence J. Lasser, former president and chief
executive officer of Putnam Investments.

The settlement represents approximately $25 million less than the company
had accrued for compensation expense for Mr. Lasser in prior years.

Pursuant to the agreement, Mr. Lasser will receive a cash payment in full
settlement of all outstanding issues related to his employment, compensation,
and departure from the company.  This cash payment represents the release of
fully vested amounts previously awarded to Mr. Lasser over the past decade
($55 million) and a portion (approximately $23 million) of amounts previously
awarded but not fully vested.

The settlement is not expected to have a significant impact on Putnam's second
quarter results when combined with costs associated with other executives who
have left Putnam.
