Fraud in Structuring and Marketing of CDO Tied to Subprime Mortgages

Last week US SEC charged Goldman Sachs & Co. and one of its vice presidents for defrauding investors by misstating and omitting key facts about a financial product tied to subprime mortgages as the U.S. housing market was beginning to falter.

SEC alleges that Goldman Sachs structured and marketed a synthetic collateralized debt obligation (CDO) that hinged on the performance of subprime residential mortgage-backed securities (RMBS). Goldman Sachs failed to disclose to investors vital information about the CDO, in particular the role that a major hedge fund played in the portfolio selection process and the fact that the hedge fund had taken a short position against the CDO.

"The product was new and complex but the deception and conflicts are old and simple," said Robert Khuzami, Director of the Division of Enforcement. "Goldman wrongly permitted a client that was betting against the mortgage market to heavily influence which mortgage securities to include in an investment portfolio, while telling other investors that the securities were selected by an independent, objective third party."

SEC alleges that one of the world's largest hedge funds, Paulson & Co., paid Goldman Sachs to structure a transaction in which Paulson & Co. could take short positions against mortgage securities chosen by Paulson & Co. based on a belief that the securities would experience credit events.

The marketing materials for the CDO known as ABACUS 2007-AC1 (ABACUS) all represented that the RMBS portfolio underlying the CDO was selected by ACA Management LLC (ACA), a third party with expertise in analyzing credit risk in RMBS. Undisclosed in the marketing materials and unbeknownst to investors, the Paulson & Co. hedge fund, which was poised to benefit if the RMBS defaulted, played a significant role in selecting which RMBS should make up the portfolio.

After participating in the portfolio selection, Paulson & Co. effectively shorted the RMBS portfolio it helped select by entering into credit default swaps (CDS) with Goldman Sachs to buy protection on specific layers of the ABACUS capital structure. Given that financial short interest, Paulson & Co. had an economic incentive to select RMBS that it expected to experience credit events in the near future. Goldman Sachs did not disclose Paulson & Co.'s short position or its role in the collateral selection process in the term sheet, flip book, offering memorandum, or other marketing materials provided to investors.

Goldman Sachs Vice President Fabrice Tourre was principally responsible for ABACUS 2007-AC1. Tourre structured the transaction, prepared the marketing materials, and communicated directly with investors. Tourre allegedly knew of Paulson & Co.'s undisclosed short interest and role in the collateral selection process. In addition, he misled ACA into believing that Paulson & Co. invested approximately $200 million in the equity of ABACUS, indicating that Paulson & Co.'s interests in the collateral selection process were closely aligned with ACA's interests. In reality, however, their interests were sharply conflicting.

The deal closed on 26 April 2007, and Paulson & Co. paid Goldman Sachs approximately $15 million for structuring and marketing ABACUS. By 24 October 2007, 83% of the RMBS in the ABACUS portfolio had been downgraded and 17% were on negative watch. By 29 January 2008, 99% of the portfolio had been downgraded.

Investors in the liabilities of ABACUS are alleged to have lost more than $1 billion.

(Jack's comment: I agree that Goldman Sachs was wrong for failing to disclose Paulson & Co.'s short interest and involvement in the collateral selection process; but in order to charge Goldman Sachs and Tourre for fraud, SEC must justify that investors' losses were caused by such misrepresentation. Those CDO investors are all institutional rather than retail. They were capable of performing an independent valuation of the CDO, which would not be affected by knowing that they were betting with Paulson & Co.)
