Stephen C. Sexauer, chief investment officer of the San Diego County Employees Retirement Association, was named interim CEO, said a news release from the $11.9 billion pension fund.
Mr. Sexauer's appointment, effective May 1, is the result of previous CEO David B. Wescoe's April 30 departure to accept a job in the private sector.
Mr. Sexauer has been CIO since 2015, after the pension fund moved from its outsourced CIO model.
Mr. Wescoe had been CEO of SDCERA since 2015, first as interim CEO, after the resignation of former CEO Brian White.
At the time, the pension fund was moving from its outsourced CIO model and in the midst of searches for a new chief financial officer, a general counsel and in-house CIO. When he was hired as interim CEO, Mr. Wescoe was president of Efficient Market Advisors, SDCERA's management consultant.
Rebecca Wilson, SDCERA's chief of staff, could not be immediately reached for further information.
