Lamar Taylor was named interim executive director and chief investment officer of the Florida State Board of Administration at its meeting Tuesday.
Mr. Taylor, the board's chief operating and financial officer, will replace Ashbel C. "Ash" Williams Jr., who is retiring Sept. 30, spokesman John Kuczwanski said in an email.
Mr. Kuczwanski could not be immediately reached for details on a search for a permanent replacement.
Mr. Williams' retirement is a result of the requirements of a deferred retirement program. While Mr. Williams is considering future opportunities following his departure, he is holding off on discussions with financial firms at this time due to potential conflicts of interest with the state board, Mr. Kuczwanski said in an August email.
Mr. Williams has headed the board since 2008 after a stint as managing director of hedge fund manager Fir Tree Partners. His 13-year run at the head of one of the largest U.S. asset owners is his second, having previously led the board from 1991 to 1996.
Mr. Taylor joined the board in 2002 and has served in multiple roles including deputy general counsel and deputy executive director.
Florida State Board of Administration oversees a total of $252.8 billion in assets, including the $199.6 billion Florida Retirement System.
