Federal Housing Finance Agency Acting Director Edward DeMarco Tuesday announced the appointment of a full time chief operating officer. Richard Hornsby will take the position of COO. Hornsby served at the Federal Reserve Bank of San Francisco for 26 years, holding a variety of senior level management and banking supervision positions. Hornsby replaces Steve Cross, who became acting COO in February. Cross remains as deputy director of the Division of Federal Home Loan Bank Regulation. Cross had been doing both roles for the last 10 months. "We determined that FHFA had reached a size, complexity and level of activity that warranted making the COO job a full-time job," a source at the FHFA told HousingWire. Jon Greenlee, a Federal Reserve veteran, was named FHFA deputy director of the Division of Enterprise Regulation. Greenlee joins FHFA from KPMG, where he was the managing director in the financial services regulatory advisory practice. In that role, he provided support to clients concerning the Dodd-Frank Act, Basel II and III, and credit, capital, liquidity and resolution planning issues, according to a statement from the FHFA.
