FBL Financial Group Inc. announced that its chief operating officer for life companies, John Currier Jr., resigned on Wednesday. The West Des Moines-based insurer said in a filing with the U.S. Securities and Exchange Commission that Currier "resigned for personal reasons, which are unrelated to FBL Financial Group's insurance operations or business outlook." Currier, who served as chief actuary of Aviva USA before joining FBL Financial as chief actuary in June 2013, was named COO of life companies in March.
