Affiliated Managers Group launched the Managers AMG Funds, a new family of no-load mutual funds. Through affiliate The Managers Funds, AMG is providing a mutual fund platform of administrative and distribution services that will help its 15 investment subsidiaries enter the mutual fund market. The first fund in the family is the Essex Aggressive Growth Fund, managed by AMG affiliate Essex Investment Management. It is managed by Essexs founder, Chairman and Chief Investment Officer Stephen D. Coulter and Vice President R. Daniel Beckham. The fund has a $25,000 minimum. The ultimate number of funds in the family will be determined by AMG affiliates, rather than by corporate headquarters, said Lee Chertavian, an AMG senior vice president.
