Introductory Note

Lehman ABS Corporation (the “Depositor”) is the Depositor in respect of the Corporate Backed Trust Certificates, Goldman Sachs Group Note-Backed Series 2003-12 Trust (the “Trust”), a common law trust formed pursuant to the Standard Terms for Trust Agreements, dated as of January 16, 2001, between the Depositor and U.S. Bank Trust National Association, as trustee (the “Trustee”), as supplemented by a Series Supplement (the “Series Supplement”) dated as of August 7, 2003 in respect of the Trust. The Trust’s assets consist solely of notes issued by The Goldman Sachs Group, Inc. The Certificates do not represent obligations of or interests in the Depositor or the Trustee.

As previously disclosed, the Registrant is a wholly-owned, indirect subsidiary of Lehman Brothers Holdings Inc. (“LBHI”). On September 15, 2008 and periodically thereafter, LBHI and certain of its subsidiaries (collectively, the “Debtors”) commenced voluntary cases under chapter 11 of title 11 of the United States Code with the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) (jointly administered proceedings, In re Lehman Brothers Holdings Inc. et al., Case Number 08-13555). LBHI and its wholly-owned broker-dealer, Lehman Brothers Inc., have sold since September 15, 2008 significant businesses, including the sale on September 21, 2008 of the investment banking business to Barclays Capital Inc., which business included the employees who historically conducted the Registrant’s business.

On December 6, 2011, the Bankruptcy Court entered an order (the “Confirmation Order”) confirming the Modified Third Amended Joint Chapter 11 Plan of Lehman Brothers Holdings Inc. and its Affiliated Debtors (the “Plan”). The Plan and the Confirmation Order were attached as Exhibit 2.1 and Exhibit 2.2, respectively, to LBHI’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 14, 2011. LBHI’s Current Report on Form 8-K filed with the Securities and Exchange Commission on December 14, 2011 contains a summary of the Plan.

On March 6, 2012 (the “Effective Date”), the Plan became effective and a notice of the Effective Date of the Plan (the “Notice of Effective Date”) was filed with the Bankruptcy Court.

The Goldman Sachs Group, Inc., the underlying securities issuer, is subject to the information reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For information on the underlying securities issuer, please see its periodic and current reports filed with the Securities and Exchange Commission (the “Commission”) under The Goldman Sachs Group, Inc.’s Exchange Act file number, 001-14965.
