CDO Manager

The job of a CDO manager was to select a Wall Street firm to supply him with subprime bonds that could serve as collateral for CDO investors, and then to vet bonds themselves. Then, they were supposed to monitor the individual subprime bonds inside each CDO and replace the bad ones, before they went bad, with better. Investors, however, usually expected that CDO managers would never even have to resort to this, because triple-A-rated bonds were supposed to be foolproof and impervious to losses. This lead many managers to feel that they did not have to closely monitor triple-A-rated bonds, and so CDO managers, in practice, did not have to do very much.
