Bear fixed-income chiefs to leave after merger

NEW YORK, May 21 (Reuters) - Two of Bear Stearns Cos' BSC.N top executives, fixed-income trading co-heads Craig Overlander and Jeffrey Mayer, have told JPMorgan Chase & Co (JPM.N) they will leave the bank once the merger is completed next month, according to an internal memo.

The memo, sent to Bear and JPMorgan executives on Tuesday, did not reveal why the two were leaving. A JPMorgan spokeswoman confirmed the memo's contents, but declined further comment.

Last month, Overlander and Mayer were among just five Bear executives offered senior management jobs at JPMorgan after the merger, which is expected to be completed around June 1. The two have been active in helping integrate the investment banks, but informed JPMorgan they did not want to remain once the merger is completed. (Reporting by Joseph A.
