How it started
History
In 1995, Moody's Corporation started a business unit providing quantitative analysis services, including credit risk assessment software and services after acquiring Financial Proformas, Inc., called Moody's Risk Management Service (MRMS).
In early 2000, Moody's acquired the Software Products Group of Crowe, Chizek & Co., then the eighth-largest accounting and consulting firm in the U.S., which brought software used by banks to analyze the risk in taking on commercial loans. The same year, MRMS partnered with RiskMetrics to develop software that combined credit risk analysis with portfolio management.
In February 2002, Moody's purchased KMV (Kealhofer, McQuown and Vasicek), a San Francisco-based quantitative risk management firm, and merged it with MRMS to create Moody's KMV. The company acquired KMV's clients and its software tool for calculating the probability of credit default, here returning the EDF, or "Expected Default Frequency"; see KMV model. Moody's KMV integrated financial modeling software from each former company and, in 2003, debuted its credit risk management system, Credit Monitor.
In 2005, Moody's acquired Economy.com, an economics research and analytics firm based in West Chester, Pennsylvania, adding services related to economic and demographic research, country analysis, and data on industrial, financial, and regional markets.
The following year, in December 2006 the firm acquired Wall Street Analytics, a San Francisco-based financial analysis and monitoring software developer founded by Ron Unz, which then became Moody's Wall Street Analytics. The acquisition brought with it software for financial risk management, including CDOnet, a tool for collateralized debt obligation (CDO) valuation.
