 Through April 2007, Goldman issued over 20 CDOs in its "Abacus" series worth a total of $10.9 billion.All together Goldman packaged, sold, and shorted a total of 47 synthetic CDOs, with an aggregate face value of $66 billion between July 1, 2004, and May 31, 2007.But while Goldman was praised for its foresight, some argued its bets against the securities it created gave it a vested interest in their failure.
