Moody’s

Moody's cheerfully performs the dismal science. The company provides credit ratings, research, credit risk management, and other services through its two primary segments, Moody's Investor Services and Moody's Analytics. Moody's Investor Services published credit ratings on more than 100,000 commercial and government entities in some 110 countries around the world. Moody's Analytics, the cornerstone of which is Moody's KMV, sells credit risk management software and provides portfolio management and training services for financial institutions. The company's famous letter ratings (ranging from "Aaa" to "C") were invented by John Moody in 1909 and are still used today.
