Freddie Mac dismissed its executive vice president of operations and technology, Mike Perlman, on Tuesday as part of a company reorganization, according to officials close to the matter.

Operations and technology is one of the largest departments at the government-sponsored enterprise, which has been operating under a federal conservatorship for almost 22 months.

Freddie had no comment on the matter but an official close to the situation said Joe Rossi, a senior vice president, would assume Perlman's duties. Besides Perlman, a small number of other information technology workers were let go, sources confirmed.

In August 2007 Freddie named Perlman executive vice president of operations and technology. Before joining Freddie, he was a managing director at Morgan Stanley where he developed operations and technology infrastructure to support the firm's fixed-income division.
