CountryWide Home CMO
In the next slides we’ll look at an actual CMO issued by Countrywide Financial. This is not an agency. Credit enhancements are achieved by a senior/subordinate structure that entails both insurance against default (for the senior tranches), and allocation of credit risk. This particular pool is designated: Countrywide Home 30-Yr: It is a $500 million pool divided into 16 tranches. Here is a hyperlink to the prospectus (.doc format).
