<p>我做了Exam1的Afternoon Session,里面有这样一条题目:</p><p>An investor is considering the purchase of Security X,which matures in ten years and has a par value of $1,000.During the first five years X has a 6% coupon with quarterly payments.During the remaining five years,X has an 8% coupon with quarterly payments.The face value is paid at maturity.Asecond 10-year security,Security Z,has a 6% semiannual coupon and is selling at par.Assuming that X has the same(bond equivalent)yield as Z,the price of Security X is closest to:</p><p>A.$943,B.$1036,C.$1067.</p><p> </p><p>这条答案的解释是:</p><p>The bond equivalent yield rate on the par bond(Z)is 6% or a 3% semiannual rate. The equivalent quarterly rate,1.031/2-1=0.014889.Security X makes 20 quarterly payments of$15 and 20 quarterly payments of $20. We need to use the cash flow function as follows:CF0=0;CF1=15;F1=20;CF2=20;F2=19;CF3=1,020;F3=1;I=1.4889;CPT→NPV=$1,067.27.Note that CF3 contains the final quarterly payments of $20 along with the $1,000 face</p><p>Payments.</p><p> </p><p> </p><p>解释里怎么对F的值发生了变动呢?这个我感觉好像没有在Level 1里出现。</p><p> </p><p> </p>
