* Haldeman stepping down effective Tuesday

* CEO Reynolds to take over as president of Putnam Funds

* Won't be replaced as chair of Putnam Investments

NEW YORK, June 30 (Reuters) - Putnam Investments said Charles "Ed" Haldeman Jr. will step down on Tuesday as chairman of the Boston investment company, ending a turbulent seven-year run at the firm.

Haldeman, 60, joined Putnam in 2002 and ran it as president and chief executive from 2003 until last year. He was credited with restoring the firm's standing with regulators after a series of trading scandals that forced out his predecessor, Lawrence Lasser.

But Haldeman wasn't able to restore the performance of Putnam's mutual funds, which also suffered from outflows. That contributed to the decision of past owner Marsh & McLennan Cos (MMC.N: Quote, Profile, Research) to sell the business to Canada's Power Financial for $3.9 billion in 2007.

Power Financial named Robert Reynolds, now 57, to lead the business last year, and he has turned its performance around with a series of management changes.

A spokesman said neither Haldeman nor Reynolds were available for interviews on Tuesday.

In a statement, Haldeman said "Bob Reynolds is doing a great job as CEO. This is a good time for me to advance to the next stage of my career. I'll always be grateful for the opportunity to have worked with so many dedicated and talented professionals."
