Credit rating agencies also play an important role in the laws and regulations of the United States and several other countries, such as those of the European Union. In the United States their credit ratings are used in regulation by the U.S. Securities and Exchange Commission as Nationally Recognized Statistical Rating Organizations (NRSROs) for a variety of regulatory purposes. Among the effects of regulatory use was to enable lower-rated companies to sell bond debt for the first time; their lower ratings merely distinguished them from higher-rated companies, rather than excluding them altogether, as had been the case. However, another aspect of mechanical use of ratings by regulatory agencies has been to reinforce "pro-cyclical" and "cliff effects" of downgrades. In October 2010, the Financial Stability Board (FSB) created a set of "principles to reduce reliance" on credit rating agencies in the laws, regulations and market practices of G-20 member countries. Since the early 1990s, the SEC has also used NRSRO ratings in measuring the commercial paper held by money market funds.
