Costa will retain his role as chief operating officer of GSCC and MBSCC, alongside his duties as president.
He joined the National Securities Clearing Corporation (NSCC) in 1984 as a vice president, and played a key part in the establishment of GSCC by NSCC in 1986. Before NSCC, Costa served for nine years with the National Association of Securities Dealers.
