R. Leslie Deak resigned as president and chief executive of Deak-Perera U.S. Inc., one of the nation’s largest foreign currency and precious metals firms.

Deak-Perera U.S.’ parent company, Deak & Co., filed a petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code in December and recently agreed to sell its stock and assets to Chan Cher Boon, a Singapore lawyer and accountant who represents an investor group.

Chan was named to replace Deak as chief executive of Deak-Perera U.S. as part of the sale agreement, the company said in a statement. Deak will continue as a director of Deak-Perera U.S.

New York-based Deak-Perera U.S., the largest remaining asset of Deak & Co., is not involved in the Chapter 11 proceedings.
