Collateral quality tests

Overcollateralisation ratio test and collateral quality tests must be met. Various rating agency tests will be met. 

This trend toward increases in automation has a number of collateral effects. In laboratories in which protocols are standardized automated systems can increase accuracy, decrease personnel costs, and enhance quality control (QC). Computerized systems are generally immune from the small slippages of attention and care that result in minor but sometimes cascading human errors through the boredom of repetitive tasks. On the other hand, computers are prone to much more spectacular errors—for example, to one-ofif recording of test results from a long line of samples. But while these errors are dramatic in scope, with effective QC efforts they are generally detectable and hence correctable. The insidious minor corruptions produced by humans are much more likely to continue undetected. 

As a matter of CDO surveillance, the quality of a CDO s collateral portfolio is monitored regularly and reported on by the portfolio administrator by way of a Trustee Report. This report details the results of various compliance tests, which are performed on an asset-by-asset level as well as on an aggregate portfolio level. Compliance tests are designed to monitor ...
