Regulation Asset Backed Securities Resource Page

Securities and Exchange Commission Regulation AB

On January 7, 2005, the SEC published Regulation AB, a final rule to codify requirements for the registration, disclosure and reporting for all publicly registered asset-backed securities including mortgage-backed securities. The purpose of this web page is to provide our members and the public with a resource for information on the regulation and on MBA activity interpreting different facets of it. We also make available on this page information and interpretations supplied by others in our industry. This webpage largely applies to residential mortgage-backed securities (RMBS). MBA has a separate webpage for commercial mortgage-backed securities (CMBS).

Scope of Regulation AB
Regulation AB (located on the SEC site at ) is a sweeping codification by the SEC of twenty years of guidance and practice in the regulation of asset-backed securities. RMBS issued or guaranteed by SEC exempt entities such as Fannie Mae, Freddie Mac and Ginnie Mac, are not subject to Regulation AB. Private placement transactions also are not covered by Regulation AB.

Most publicly issued, non-agency RMBS are subject to Regulation AB. The growth in this sector has been rapid, and during 2005, non-agency, or private-label RMBS issuance outpaced the volume of RMBS issued by Fannie Mae, Freddie Mac and Ginnie Mae combined. The regulation is significant to MBA members who originate or service mortgages that are used in non-agency RMBS transactions, and members who act as issuers, sponsors, servicers, trustees, paying agents, or vendors of certain other types for RMBS deals.
