According to the asset manager, the fund will be managed by George Greig and Ken McAtamney, and seeks long-term capital appreciation by investing in foreign firms with above-average returns on equity, strong balance sheets, and consistent, above-average earnings growth, which creates a balanced portfolio of leading conglomerates.

William Blair Investment Management CFA, head and a member of the firm’s executive committee Michelle Seitz said the firm is pleased to offer its clients and investors the William Blair International Leaders strategy utilizing its International Team’s proven, time-tested process.

"Supported by an experienced team of research analysts, portfolio managers, and traders, George and Ken will search for the highest-conviction companies with the strongest corporate performance that we believe will be the long-term category winners," Seitz said.

George Greig, who accompanied the company since 1996, has a proven track record of managing national and international mutual funds.

Ken McAtamney joined William Blair in 2005 as part of the International Team and works as a co-portfolio manager for the Global Growth and International Leaders strategies.
