Steve Sterling will head up Lehman Brothers' U.S. loan efforts and Richard Howell will lead the European side as Mark Lies, global head of leveraged finance, moves from New York to London to head up the high-yield loan and bond origination business. "It's a spot we need to pick up a little bit given that we've shown pretty significant relevance in the U.S.," Lies said. "We've conquered what we wanted to here--we're moving on into the new frontier." Lies has been commuting from New York to London for the last two months and will make the permanent move in June when his children are done with school, he said. Sterling will take Lies spot as vice chair of the board of directors on the The Loan Syndications and Trading Association.
