Getting to the heart of the experience modification factor (Ex Mod, X-Mod, the Mod, etc.) requires answering three questions: 1) Why are experience modification factors developed and used? 2) How is the experience modification factor developed and calculated? and 3) Which has greater effect on the experience modification calculation, claims frequency or claims severity?

In answering all three questions, this e-book clears up the mystery behind the development of the experience mod. Regardless what the split point is now or will be in the future, the concepts detailed in this book apply to guide the reader through the process. Knowing and understanding the process for developing the experience mod makes finding mistakes in the calculation almost fun (because finding mistakes in the mod will no longer be challenging).
