Weil, Gotshal & Manges is the latest New York firm with a significant Silicon Valley presence to lace up its boots and climb the slippery slope of the associate salary mountain. But just how high will the No. 10 firm on the 1999 Am Law 100 list go?

Like that of its cautious N.Y. counterparts — Skadden, Arps, Slate, Meagher & Flom and Davis Polk & Wardwell — the payday forecast at Weil is not yet clear. Matthew Powers, managing partner of the firm’s 37-attorney Menlo Park office, says it is too early to say what the top take-home pay for Weil associates might be. Instead, he says only that the top performers will make at least as much, if not more, at Weil than they could make anywhere else.
