Chapter 15: Evaluation of Methods

Study Tips

This is a really great chapter because ties together concepts from all previous chapters. The only thing that's new is a formula for calculating expected emergence. There are 2 versions and they are both pretty easy:

• expected emergence of reported losses
• expected emergence of paid losses

Most of the exam questions from this chapter ask you to do one or more of the following:

• evaluate the accuracy of an estimate from a given reserving method
• identify a scenario that could changes in estimates for a given reserving method between successive evaluation dates
• identify a scenario that causes differences in estimates between 2 different reserving methods
• suggest an adjustment or alternate method to improve accuracy of estimates

It's a heavily tested chapter and is an excellent way to review the concepts related to all the different reserving methods from previous chapters.
