6. 5 Overview of CDOs Collateralized Debt Obligations (“CDOs”) are securities issued to finance a diversified pool of credits. The portfolio of securitized assets in a CDO is typically financed by a credit-tiered capital structure, consisting of both investment grade and non-investment grade tranches of debt, supported by an equity tranche. The majority of the financing for a CDO is usually provided by a large AAA rated tranche of debt, thereby making the weighted average cost of capital significantly cheaper than the return on the portfolio of assets. Below the rated debt tranches in the structure of a CDO is a tranche of Equity. This tranche is the beneficiary of the spread differential between the returns on the portfolio of assets and the weighted average cost of financing. What are CDOs?

Baa3 and Ba3 ratings are deemphasized as debt rated at these levels is no longer commonly issued. Additionally, there were only 194 and 212 observations at the Baa3 and Ba3 levels, respectively, while there were 1230, 417, 684, and 363 observations for the Aaa, Aa2, Baa2, and Ba2 ratings, respectively. 2. Figures are from "theoretical" corporate transition matrix. Moody’s weighted each year’s one-year corporate transition rates by the number of CDO ratings outstanding at each rating level at the beginning of the year.
