Compute the Macaulay duration under the following conditions: a. A bond with a fouriyear term to maturity, a 10% coupon (annual payments), and a market yield of B\%. Do not round intermediate caiculations: Round your aniwer to two decimal placts. You may use Appendox C to answer the questions. Assume $1,000 par value. years b. A bond with a four-year term to maturity, a 10% coupon (annual payments), and a market yeld of 12%. Do not round iotermediate calculations. Round your ananer to two decimal places, You may use Appendoc C to answer the questions. Assume $1,000 par value. years C. Compare your answers to Parts a and b, and discuss the implications of this for elasslcal immunication. As a market yleld increases, the Maceulay duration Part b is perfectly immunized. If the duration of the portfollo from Part a is equal to the desired investment horizon the portiolio from
