GLOSSARY AND APPENDICES
The document "Appendix 0 - Basic glossary" contains the definition of some of the most important and ubiquitous terms used in the book. This is work in progress!
The document "Appendix 1 - Earned vs written" contains more material on a topic that was only touched on briefly in Chapter 20.3.1: what earned premium/exposure is and how it is calculated in situations more complex than that envisaged in Equation 20.3
The document "Appendix 2 - Rate change calculations" expands on the content of Section 19.4.2, "Monitoring rate changes", explaining how the rate change for a contract and the average rate change for a portfolio can be calculated.
