Arkansas State Police Retirement System, Little Rock, hired Frontier to manage a $16.1 million active domestic midcap growth equity mandate and Marvin & Palmer to run a $6.9 million active international emerging markets mandate. The hirings are the result of a recommendation from the $230 million plans consultant, Salomon Smith Barney, said Bill Van Cleve, executive secretary. Funding will come from reductions to several managers in different asset classes, he said. He would not specify the managers or styles. No managers were terminated as a result of the hirings.
