老师您好！ reading24课后题最后一道，这个表该如何理解？能否麻烦讲解一下具体数字的含义？以及如何看出ABC各是什么变动？ 谢谢啦！

Solution to 5: Hedging exposure to GBP and EUR results in a six-month gain of 49 bps and 85 bps, respectively, as shown in the beginning of problem 4. The currency exposure should be hedged unless these currencies are expected to appreciate against the USD by more than these amounts over the next six months.

In the case of the 10-year this would mean paying fixed at 3% timed to match the 3% annual coupon from the bond and receiving a spread to the 6-month floating rate. (Institute 176) Institute, CFA. 2019 CFA Program Curriculum Level III Volume 4. CFA Institute, 5/2018. VitalBook file. 老师您好！ 请问reading24第section 5中的example 4中的这句话，paying fixed at 3%，为什么不是10年期的5.91%？ 我看其他题目中都是以题目中给出的表格中的各期的YTM为互换固定方利率呀 谢谢！

By construction, the forward rates are the sequence of future one-period discount rates imbedded in the value of all swap tenors today. At the end of the first period, the current short-term (6-month) rate will drop out of the sequence. If the rest of the series remains the same—which is what it means for the curve to move to the forward rates—then the fixed side of every swap will increase in value by exactly the current short rate. Of course, that is the rate being paid on the floating side of the swaps, so each tenor breaks even. (Institute 140) Institute, CFA. 2019 CFA Program Curriculum Level III Volume 4. CFA Institute, 5/2018. VitalBook file. 老师您好！ Reading24P140页的案例最后一段， 1、这个break even怎么理解呀？ 2、书中说“then the fixed side of every swap will increase in value by exactly the current short rate”，在上文中increase in value不是33bp吗？难道应该是the current short rate—2.03%？实在不理解！ 谢谢老师的耐心！
