XBRL Implementation Guide for Nationally Recognized Statistical Rating Organizations1

Introduction

The Securities and Exchange Commission ("Commission") recently adopted new rules relating to the disclosure requirements for ratings actions of nationally recognized statistical rating organizations ("NRSROs").

The Commission adopted a disclosure rule in February 2009 to require any NRSRO to make and retain an internal record of the ratings history of each current credit rating. From that record, an NRSRO that operates under the "issuer-pay" model is required to publicly disclose a random sample of 10% of the ratings issued, with certain caveats ("10% Disclosure Rule"). The 10% Disclosure Rule requires an NRSRO to make the data publicly available in XBRL format.

Additionally, the Commission adopted a disclosure rule to require all NRSROs to make publicly available all credit rating action history related to outstanding credit ratings that were issued as of June 2007 ("100% Disclosure Rule"). The 100% Disclosure Rule also requires an NRSRO to make the data publicly available in XBRL format.

What XBRL taxonomy should be used for the rating actions disclosures?

The directory of taxonomies supported for the XBRL programs can be found at http://sec.gov/info/edgar/edgartaxonomies.shtml.

The following taxonomy architecture document and technical instructions provide guidance when preparing XBRL files for these disclosure requirements to help ensure the taxonomy is being used consistently.

Where can the rating actions disclosures in XBRL format be found?

The rating actions disclosures in XBRL are required to be posted to each NRSROs website in accordance with compliance timelines in the adopting release. The Commission staff intends to create a central directory of the credit ratings XBRL files which will be made available from this webpage.
