Questions and parts of some solutions have been taken from material copyrighted by the Casualty Actuarial
Society and the Society of Actuaries. They are reproduced in this study manual with the permission of the
CAS and SoA solely to aid students studying for the actuarial exams. Some editing of questions has been
done. Students may also request past exams directly from both societies. I am very grateful to these
organizations for their cooperation and permission to use this material. They are, of course, in no way
responsible for the structure or accuracy of the manual.
Exam questions are identified by numbers in parentheses at the end of each question. CAS questions have four
numbers separated by hyphens: the year of the exam, the number of the exam, the number of the question,
and the points assigned. SoA or joint exam questions usually lack the number for points assigned. W
indicates a written answer question; for questions of this type, the number of points assigned are also given.
A indicates a question from the afternoon part of an exam. MC indicates that a multiple choice question has
been converted into a true/false question. Page numbers (p.) with solutions refer to the reading to which the
question has been assigned unless otherwise noted.
Page references refer to Samuel A. Broverman Mathematics of Investment and Credit (2008); James W. Daniel

Interest (2008); Robert L. McDonald, Derivatives Markets, (2006); and Chris Ruckman and Joe Francis,
Financial Mathematics (2005).
Although I have made a conscientious effort to eliminate mistakes and incorrect answers, I am certain some
remain. I am very grateful to students who discovered errors in the past and encourage those of you who
find others to bring them to my attention. Please check our web site for corrections subsequent to
publication. I would also like to thank Graham Lord for checking some of the solutions in the manual.

B1. A bond with a $100 par value has 5.25% annual coupons and is due to mature at the end of 16 years. The
bond will be redeemed at maturity for an amount equal to its par value less a service charge. The service
charge is equal to 25% of the excess (if any) of the par value over the purchase price. A prospective
purchaser offers a price that will produce a yield equivalent to a 7% annual effective interest rate, taking
into account the deduction of the service charge. It is noted that (1.07)16 = 3. In which of the following

B8. Calculate the PV of the redemption value and use to calculate the price of the bond:
P = K + (g/i)(C K) = (1,000)(1.05)-2n + [.06/.05][1,000][1 (1.05)-2n]
P = 1,200 (200)(1.05)-2n
