Bad book for SOA exam, but oh well.
Format: Paperback
While required by Society of Actuaries as the textbook for Short Term Actuarial Models exam, I could not recommend this textbook for any other purposes. Written by two Canadian actuaries, a lot of terms and explanations used in this textbook cannot be transferred into US P&C insurance.
It fails to explains insurance's purpose and products effectively and as an intro book with unnecessary sentences to deliver personal thoughts.
It is also a mess in following sections on ratemaking and reserving. I cannot sense a flow from this book that guides readers in an approachable manner.
Overall, author compromises the size AND the quality.
