Calculate the net coupon exchange for the first perioif LIBOR is 5% the beginning of the perioan5.5% the enof the perioA.Fixerate payer pays US0.B.Fixerate payer pays US25,000.C.Fixerate payer pays US50,000.Fixerate payer receives US25,000.ANSWER: BThe floating leg uses LIBOR the beginning of the perio plus 50bp, or 5.5%. The payment is given $10,000,000 × (0.06-0.055) × 0.5=25,000.从哪里看出来是付固定，收浮动的？
NO.PZ2016082402000063 Calculate the net coupon exchange for the first perioif LIBOR is 5% the beginning of the perioan5.5% the enof the perio 整个题目，还是最后一句话中的“the net coupon exchange for the first perio比较难以理解。 举例子来说，是指T-0时开始，LIBOR is 5%，半年后是“ the first perio么？半年后的LIBOR is 5.5%么？
请问这道题给出 5.5% the enof the perio 的意义是？
是不是固定换浮动的swap也是起初决定期末的利率? 那第一期期末的Libor就是决定第二期settle的？
如果这道题涉及到往0折现 也用5吗
