Tulsa County Employees' Retirement System, Tulsa, Okla, hired Fayez Sarofim to manage $17 million in active domestic large-cap core equities for the $136 million pension plan, said Robert E. Hyer, deputy treasurer. Funding came from terminating Morgan Stanley, which ran $17 million in the same style, he said; he declined comment on the reason for the termination. The assets have been in a temporary S&P 500 index fund managed by State Street Global Advisors for the past four months; $13 million remains in that account, he said. The plan's asset allocation is split 50/50 between equity and fixed income. Marquette Associates advised.
