Moody’s Corporation

A global provider of credit ratings, data, and risk analytics, Moody's works through two arms: Moody's Investors Service, which issues letter-grade credit ratings on bonds, and Moody's Analytics, whose software and research help banks, insurers, and governments manage risk. Founded by financial analyst John Moody, the company gave its name to the modern rating business: after the 1907 market panic cost him his first publishing venture, he returned in 1909 with ratings for railroad bonds that introduced the now-familiar Aaa letter grades.
