Troy Rucker, managing director, president and CEO of Russell Investments' investment implementation services business, and Michael DuCharme, Russell's head of currency strategy, have left the firm, confirmed spokesman Steve Claiborne.
Additionally, Robert Bishop, managing director, global trading, will leave Russell in August, Mr. Claiborne said.
Mr. Claiborne would not say whether they were terminated or resigned, and efforts to reach the three men were unsuccessful.
Their duties will be taken over by members of Russell's investment implementation unit, which provides currency management, trade execution, overlay and transition management services.
"Implementation services is as important as ever to Russell Investments' multiasset value proposition," Mr. Claiborne said in an email. "While some implementation services and respective teams shifted within the organizational structure, they remain intact and nothing has changed in terms of the firm's ambition to grow and serve more clients."
