(The Wall Street Journal) -- McGraw-Hill replaced the top executive at Standard & Poor's as criticism of the company's financial-information division mounts for its role in the unfolding sub-prime mortgage crisis.

Kathleen Corbet, S&P's president, is leaving to pursue other opportunities, McGraw-Hill said yesterday, without elaborating. She will be succeeded by Deven Sharma, 51 years old, a senior McGraw-Hill executive who has been at S&P since late last year.
