Newton-based CommonWealth REIT has appointed Ann Logan and Ronald Artinian as independent trustees to its board of trustees.

Logan previously served as an independent director of PHH Corp. between 2005 and 2010. Logan worked at Fannie Mae until 2000, serving as executive vice president between 1998 and 2000 and as Fannie Mae’s chief credit officer between 1993 and 1998. She currently serves on the boards of trustees of Bryn Mawr College, the Georgetown Preparatory School and the Washington Middle School for Girls.

Artinian has been on the board of trustees of the Reserve Funds since 2006. He also has served on the board of trustees of First Real Estate Investment Trust of New Jersey where he is currently chair of the audit committee and a member of the executive and compensation committees. He previously worked at Lehman Brothers and Smith Barney as a senior executive.

Both were identified by the search firm Korn / Ferry International and were recommended to join the board by CommonWealth REIT’s nominating and governance committee, which is comprised solely of independent trustees.

The CommonWealth REIT board also approved changes to the company’s Governance Guidelines to provide for minimum share ownership by board members. Within five years of joining the board a trustee is expected to accumulate and to continue to own at least 20,000 common shares, which is about five times the total current annual compensation received for serving as an independent trustee.
