Mastering conceptsofpresentandfuturevaluesofstreamsofcashflowsunderdifferentinter- estrateenvironments iscoreforactuariesandfinancialeconomists. Itiswiththese perspectives inmindthatwewritethistextbook. This book covers the body of knowledge required by the Society of Actuaries (SOA) for its Financial Mathematics (FM) Exam. In this second edition, we expand the book to include topics introduced by the SOA in the FM Exam from 2017 onwards. In particular, in Chapter 3 we include the coverage of interest rate swaps. Wealso add a chapter on the determination of the rates of interest of vari- ous financial securities.
