为什么减去红笔标注那一项呢

想請問老師Swaption的valueation真的不會考嗎?在notes上第65,66頁 因為我發現他的計算跟前面IRS的valuation不一樣 IRS新valueation算法: (new swap%-old swap%)直接乘discont factor最後再*NP 但swaption得先算net cash saving, 而且在這裡要先乘NP??? 然後才能*discount factor得到PV(saving) 可以請老師解釋一下嗎,謝謝

老师你好，关于warrants 对稀释每股收益的影响，if the exercise price is less than the weighted average market price during the year, the effect of their conversion is to increase the weighted average number of common shares outstanding, causing diluted EPS to be lower than basic EPS. If the exercise price is equal to the weighted average market price, the number of shares issued equals the number of shares repurchased. Therefore, the weighted average number of common shares outstanding is not affected and diluted EPS equals basic EPS. If the exercise price is greater than the weighted average market price, the effect of their conversion is anti-dilutive. 老师上课说如果执行价格高于平均市场价格，不行权，而原版书这里说如果执行价格高于平均市场价格，行权会有反稀释作用，怎么理解呢？执行价格高于市场平均价格，到底是行权还是不行权？

老师。经济分析利率和本币升贬值这里有点矛盾。 借利率低国货币投利率高国，所以对利率低的国家货币需求高，利率升高，货币升值。 还有一个分析是inflow使本币升值。 inflow不就是货币供应s升高，本币应该贬值吗？
