NEW YORK Moodys Investors Service upgraded its ratings of Imperial Bancorp of Inglewood, Calif., to A1, from Baa3, and of Imperial Bank to A3, from B1.
The change comes after Comerica Inc.s San Jose, Calif. unit bought Imperial on Jan. 30. Analyst Rosemarie Conforte said in a research note that Imperials debt ratings were raised to conform with Detroit-based Comericas rating, which she said was A1.
As a bank affiliate of Comerica Bank, Imperial Bank now benefits from Comericas much bigger and more diversified franchise, Ms. Conforte wrote.
