NEW YORK (Bloomberg) - Bermuda-based MF Global Ltd., the derivatives broker that lost 94 percent of its market value last year, said Simon Healy resigned as chief executive officer of European operations.

Laurence O'Connell, CEO of Asia-Pacific operations, and chief operating officer Karel Harbour will take over Mr. Healy's duties on an interim basis, the company said on Friday in a filing with the US Securities and Exchange Commission.

No termination-related payments will be made to Mr. Healy because MF Global considers his resignation voluntary, the company said.
