NEW YORK (Bloomberg) — Evan Greenberg, the chief executive officer of Ace Ltd, said the company is poised to benefit as the insurer and its rivals charge more to clients for commercial coverage.“From what I see today, I am more bullish about the pricing environment in the US than I have been for some time,” Greenberg said in a conference call yesterday held by the Zurich-based insurer. Excluding property coverage, “the level of rate increases we received in the fourth quarter, which has continued into the first quarter, is the best we’ve seen in a number of years.”
