ACF329 Practice Problems for Final Exam Warning: this is not a sample test, and it only includes material not covered in the midterms. Name: Instructions: You should use one of the SOA approved calculators on this worksheet. These problems are from the sample Exam FM problems you can access from the Society of Actu- aries webpages. Some of them are slightly modified. Make sure you know how to use your calculator. I will not answer any questions during the exam on how to use the calculator. For example, “BGN” versus “END”; although it’s possible to calculate all annuity symbols with just one of them, it may be more convenient to be able to use both. 1. Important! This one item is not a problem, but a written correction of an error I made during class. One of the formulas from Section 3.9 (Annuities with payments in arithmetic progression) was presented incorrectly. In class, I wrote ( I P,Q ¨ a ) i = P ¨ a i + Q d ¨ a i = P d + Q d 2 . That was incorrect! The correct formula is ( I P,Q ¨ a ) i = P ¨ a i + Q d a i = P d + Q id I apologize for any confusion I may have caused by this error. I have never used this formula to solve any problems in class so hopefully only a minor correction is needed in your notes. 2. You are given the following information with respect to a bond: Par amount: 1000 Term to maturity: 3 years annual coupon rate: 6% payable annually Term Annual Spot Interest Rates 1 7% 2 8% 3 9% Calculate the value of the bond and the annual effective yield rate for the bond if the bond is sold at a price equal to its value.

3. A 1000 bond with semi-annual coupons at i (2) = 6% matures at par on October 15, 2020. The bond is purchased on June 28, 2005 to yield the investor i (2) = 7%. Calculate the purchase price to the nearest whole number. Assume simple interest between bond coupon dates. Also, assume that there are 183 days between coupon dates, and note that: Date Day of the Year April 15 105 June 28 179 October 15 288 4. The current price of an annual coupon bond is 100. The derivative of the price of the bond with respect to the yield to maturity is - 700. The yield to maturity is an annual effective rate of 8%. Calculate the duration of the bond. 5. Calculate the duration of a common stock that pays dividends at the end of each year into perpetuity. Assume that the dividend is constant, and that the effective rate of interest is 10%. 6. Calculate the duration of a common stock that pays dividends at the end of each year into perpetuity. Assume that the dividend increases by 2% each year and that the effective rate of interest is 5%.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
