William Sterling, Stephen Waite, Ian Borsook and C.I. Mutual Funds, a Canadian mutual fund firm, have opened Trilogy Advisors, a new asset management firm that will primarily run global and international equities. Trilogy currently manages $2.5 billion in assets for C.I. Mutual Funds. Mr. Sterling was a managing director with Credit Suisse Asset Management until June. Mr. Waite had been a vice president and international equity portfolio manager for CSAM. Mr. Borsook had been a vice president and quantitative analyst for CSAM. C.I. Mutual Funds took the $2.5 billion in assets from CSAM, specifically in funds in which Mr. Sterling and his team were managing the money, said William Holland, chief operating officer for the Toronto-based firm. He added that CSAM is still subadviser to about $2 billion in assets for C.I. Mutual Funds. A spokesman from CSAM declined to comment. Messrs. Sterling, Waite and Borsook own 55% of the new firm. Mr. Sterling is president and chief executive, while Messrs. Waite and Borsook are both managing directors. C.I. Mutual Funds owns the remainder of the firm. Mr. Sterling said he expects to begin calling on U.S. pension funds by the beginning of 2000. He added that the group has signed a letter of intent with its partner to launch C.I. Global Advisors, which will focus on marketing to Canadian clients. C.I. Mutual Funds is slated to be the majority owner in that deal with a 55% stake, he said. He and Messrs. Waite and Borsook will own the rest.
