NOTE 1 DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Moody’s is a provider of (i) credit ratings, (ii) credit, capital markets and economic research, data and analytical tools, (iii) software solutions and related risk management services, (iv) quantitative credit risk measures, financial services training and certification services and (v) outsourced research and analytical services to institutional customers. Moody’s has two reportable segments: MIS and MA.

MIS, the credit rating agency, publishes credit ratings on a wide range of debt obligations and the entities that issue such obligations in markets worldwide. Revenue is derived from the originators and issuers of such transactions who use MIS ratings in the distribution of their debt issues to investors.

MA, which includes all of the Company’s non-rating commercial activities, develops a wide range of products and services that support financial analysis and risk management activities of institutional participants in global financial markets. Within its Research, Data and Analytics business, MA distributes research and data developed by MIS as part of its ratings process, including in-depth research on major debt issuers, industry studies and commentary on topical credit-related events. The RD&A business also produces economic research as well as data and analytical tools such as quantitative credit risk scores. Within its Enterprise Risk Solutions business (formerly referred to as Risk Management Software), MA provides software solutions as well as related risk management services. The Professional Services business provides outsourced research and analytical services along with financial training and certification programs.
