Catherine Walker was named acting CEO of the $4.8 billion Alameda County Employees' Retirement Association, Oakland, according to a letter to retirement system officials obtained by P&I Daily.
Ms. Walker, the system's assistant CEO, replaces Charles Conrad, who is taking a personal leave of absence, according to a letter sent on May 21 by Tammi Young, Ms. Walker's executive assistant, to the system's board and other system officials.
A separate letter from Ms. Walker dated July 16, also obtained by P&I Daily, states that Mr. Conrad told her that he will not be returning to the retirement system.
In separate e-mails last week, Marguerite M. Malloy, the system's associate counsel, said Mr. Conrad announced his intention to retire in January and the board expected to hire a consultant to begin a search for a new CEO.
However, Ms. Malloy also stated that Mr. Conrad had not retired. It is unclear when Mr. Conrad's personal leave will end.
Ms. Walker and Ms. Malloy have not responded to requests for more information. Mr. Conrad was unavailable for comment.
