Suppose you observe the following market data on debt securities: Note: Data deviates from the current market conditions as it simplifies the calculations. Required: (a). What are the continuously compounded zero-coupon yields for 6 months and one year, respectively? Report your answer in percentage (\%) with 4dps. (b). What is the duration of the following default-free bond portfolio? (4 dps) Note: Each bond has a face value of $1.00 and coupons are paid semi-annually. You should assume the zero-coupon rate calculated in part a above. Note: Use the following formula to measure the duration of the bond portfolio, i.e., DB=i=1ncieriiii=1nticieriti, where ti,ci, and ri denote for term, cash-flows, and zero-coupon yield for the ith period
