Ohio Public Employees Retirement System, Columbus, put two active international equity managers on watch for performance: Driehaus Capital Management, which runs $270 million; and Oechsle International Advisors, $350 million. Both managers have underperformed their benchmark, the MSCI All Country (ex-U.S.) index, since 1999, said Neil Toth, director of investments at the $48.5 billion plan. The firms will remain on watch for six months, after which plan officials will decide how to proceed. Spokesmen for Driehaus and Oechsle did not return calls seeking comment by press time.
