Acadia Realty Trust Announces Succession Plan for Its Accounting Division

WHITE PLAINS, N.Y.--(BUSINESS WIRE)--May 17, 2011--Acadia Realty Trust (NYSE:AKR), today announced that as of January 1, 2012, Jon Grisham, presently Senior Vice President and Chief Accounting Officer shall assume the role of Chief Financial Officer. Michael Nelsen, currently Senior Vice President and Chief Financial Officer, shall remain with Acadia through and beyond the transition as a Senior Officer and Senior Accounting and Financial Principal.

Mr. Nelsen has been with Acadia since 2003, joining after a career in public accounting, as well as with George Soros’ real estate ventures. Mr. Grisham also had a career in public accounting, joining the predecessor to Acadia in 1993 as Controller. Mr. Grisham has steadily assumed more responsibility over the years with a key role in capital markets execution, as well as overseeing the entire accounting and lease administration functions.

Kenneth F. Bernstein, President and CEO, stated “I want to personally thank Mike Nelsen for his untiring efforts in helping build Acadia into the company it is today. He has built an excellent team and I look forward to his continued contribution to Acadia. Jon’s succession is a key indicator of the bench strength at Acadia and is part of the normal progression and maturity in senior management. I have worked with Jon since 1998 when our private company recapitalized Mark Centers. He has played a key role throughout the entire period. I look forward to continuing to work with Jon and view his promotion as extremely well deserved.”
