Question 1

RM1,000 is invested at a market rate i. Inflation is at a constant 3.5% per annum. At the end of 15 years, the purchasing power of the investment has increased by 55%. Determine i.

 

Note that RM1,000 is not a must for this question. 

Question 2

Don invests RM1,000 at time 0. His nominal rate of interest is 8% in year 1, 7% in year 2 and 6% in year 3. The rate of inflation is 4.5% in year 1, 3.5% in year 2, and 3% in year 3. What is Don’s equivalent level annual real rate of interest/return over the 3-year period?

 

Note that RM1,000 is not a must for the question.

Question 3

Question 5 

An insurance company has an obligation to pay the medical costs for a claimant. Average annual claims costs today are RM5,000, and medical inflation is expected to be 7% per year.

Find the present value (using the real rate of interest) of the obligation if the annual (nominal rate of) interest rate is 5%.

        Question 15

        A company's liabilities include loss reserves, which are liability reserves set aside to make future claim payments on policies which the company has already sold. You believe that these liabilities, totalling RM100 million on December 31, 2016, will be paid out according to the following schedule

        Find the modified duration of the company's loss reserves. Assume that the annual interest rate is 8%, and that all losses paid during a given calendar year are paid at the midpoint of that calendar year.

        Question 15

        Consider the following bonds.

        • Bond A with price 2,000, modified duration 8 and convexity 64. ? Bond B with price 1,000, modified duration 6 and convexity 36; and
        • Bond C with price 800, modified duration 5 and convexity 25. Calculate the modified duration and convexity of the portfolio.

          Question 17

          For a 25-year home mortgage with level payments and an interest rate of 9% convertible monthly, find the modified duration and the convexity of the payments.

          Prove that P(i ??i) ? P(i)?1?v?i? and P(i ? ?i) ? P(i)?? ?1?v?i ? c2 (?i)2???   . Use the results to

          estimate the new bond price (with annual coupon) if the yield rate increases 0.5% using both approximations. Given the yield rate i = 5%, initial price of bond = 1000, v ?10 and c ?100.

          Question 19

          A client deposits RM100,000 in a bank, with the bank agreeing to pay 7% effective for two years. The client indicates that half of the account balance will be withdrawn at the end of the first year. The bank can invest in either one-year or two-year zero-coupon bonds. The one-year bonds yield 9% and the two-year bonds yield 10%. Develop an investment program based on immunization.

Question 21

An insurance company has an obligation to pay RM1,000,000 at the end of 10 years. It has a zerocoupon bond that matures for RM413,947.55 in 5 years, and it has a zero-coupon bond that matures for RM864,580.82 in 20 years. The effective yield for assets and liability is 10%. Determine whether the company's position is fully immunized.

Question 22

An investor has a single liability of RM1,000,000 due in 15 years' time. The yield on zero coupon bonds of any term is currently 5% per annum, and the investor possesses cash equal to the present value of his liability. He wishes to invest in 10-year and 20-year zero coupon bonds in such a way that he will make a profit on any immediate change in the force of interest. How much of each security should he buy, and how large a profit will he make if the rate of interest per annum immediately becomes 0.01, 0.02, 0.03, 0.04, 0.06, 0.07, or 0.08?

Question 23

(Bond I)  A 1-year 4% annual coupon bond with a yield rate of 5% (Bond II) A 2-year 6% annual coupon bond with a yield rate of 5%.

 

Calculate X.

Question 24
