Moody's Investors Service, a leading global credit rating, research and risk analysis firm, publishes credit opinions, research, and ratings on fixed-income securities, issuers of securities and other credit obligations. Credit ratings and research help investors analyze the credit risks associated with fixed-income securities. Ratings also create efficiencies in fixed-income markets and similar obligations, such as insurance and derivatives, by providing reliable, credible, and independent assessments of credit risk. For issuers, Moody's services increase market liquidity and may reduce transaction costs.
