C3 Phase II Pre-packaged asset scenarios


To supplement its recommendations for implementing C3 Phase II, the Academy’s Life Capital Adequacy Subcommittee has developed two sets of the pre-packaged scenarios. The December 2005 scenarios are intended to enhance, not replace, the original March 2005 scenarios.

Also provided are documentation and guidance for using the scenarios, and a tool that allows companies to select a subset of representative scenarios from the full sample of 10,000. The December package also includes an enhanced version of the C3 Phase I RBC interest-rate generator. Much of this material was developed by Geoffrey Hancock for the LCAS.
