求解

NO.PZ2019052801000122问题如下 Two companies, AanXYZ, have signea 2-yeplain vanilla interest rate swwith $500m notionprincipal. Accorng to the swap, Awill pXYZ perioc floating rate, anXYZ will pperioc fixerate to A2.4%. The payment will ma semi-annually. The 6-month LIBOR rate are followsWhis the net payment for the enof the first perioA.XYZ pays A$3,500,000 .B.XYZ pays A$6,000,000 .C.Apays XYZ $2,500,000 .Apays XYZ $3,500,000 .A is correct.考点Pricing AnValuation Of Interest Rate Swaps解析因为Swap的货币相同，因此只用支付固定与浮动之间的净值就可以。根据Swap协议，在第一期半年之后，ABC向XYZ支付浮动利率，Floating payment= $500 million x 0.01 x 0.5 = $2,500,000XYZ向ABC支付固定利率，Fixepayment = $500 million x 0.024 x 0.5 = $6,000,000所以，Net payment = $6,000,000 - $2,500,000 = $3,500,000，应该是XYZ向ABC支付。这个题如果是两年期互关协议，一个阶段是半年，为什么表里能到第五阶段呢，应该只到第四阶段吧，如果按答案里都乘以0.5理解的话。

NO.PZ2019052801000122 这里的1%的libor是不是指 t=0.5 到 t=1 之间的利率

NO.PZ2019052801000122 老师你好，在每个settlement te浮动利率那部分不是会回归面值吗？为什么V（float，t=0.5）不等于500m,而是要再乘上libor。V(fixe为什么不等于t=1、1.5、2三个时刻的现金流折现？这里给的libor rate不是用来折现的吗？不太懂什么时候用题目中给的libor来求现金流，什么时候用来折现？麻烦老师讲一下，谢谢！
