One experienced CDO trader characterized the Class V III portfolio in an e-mail as “dogsh!t” and “possibly the best short EVER!” An experienced collateral manager commented that “the portfolio is horrible.” On Nov. 7, 2007, a credit rating agency downgraded every tranche of Class V III, and on Nov. 19, 2007, Class V III was declared to be in an Event of Default. The approximately 15 investors in the Class V III transaction lost virtually their entire investments while Citigroup received fees of approximately $34 million for structuring and marketing the transaction and additionally realized net profits of at least $126 million from its short position."
