NEW YORK (Bloomberg) — Bermuda-based MF Global Ltd., the futures broker that lost $141 million earlier this year on an unauthorised employee trade, appointed Michael Roseman as chief risk officer.

The hire comes about four months after chief executive officer Kevin Davis promised to tighten risk controls at the Hamilton, Bermuda-based company. The trading loss, reported in February, as well as earnings misses and the need to raise capital to pay off a bridge loan, helped send MF Global shares down 77 percent this year.

Roseman will be responsible for global risk at MF Global, a position that will cover market, credit and operational duties, the company said in a statement yesterday. Prior to joining MF Global, Roseman served as chief risk officer for the Americas at Newedge Group.
