分母34哪里来的？

最后这道题没听懂，看了同样的同学提的问题也没有懂。都持有到期了，ytm变化了，realizedreturn变大，那为什么是less呢

Jordan responds, “Alpha’s decision to capitalise the cost of its new computer system instead of expensing it results in lower net income, lower total assets, and higher cash flow from operating activities in the current fiscal year. Alpha’s decision to capitalise its interest costs instead of expensing them results in a lower fixed asset turnover ratio and a higher interest coverage ratio.”Q. Jordan’s response about the ratio impact of Alpha’s decision to capitalise interest costs is most likely correct with respect to the:interest coverage ratio.fixed asset turnover ratio.interest coverage and fixed asset turnover ratios. 想问下这道题为什么capitalize interest之后interest coverage ratio不是更高呢？interest expense不是变少了吗？

如果这题不是modified久期的话，这个题要怎么算呢/？

不用考虑7%的coupon了么，pmt里

题9，当年买的long-lived asset, 不应该第二年的B/S计提折旧费用么，in the fiscal year是指当年还是第二年呢？

c选项，equity上升怎么不对？equity上升liability也可能下降，导致asset也是下降的

net profit 有很多因素影响呀，也可能2009年后减值更多，怎么就b正确呢，不理解

4分26处，分母变成负的一次方后，为什么负号可以挪到左边？

为什么这题不能用Inventory的BASE法则来算，COGS=beginning inventory + purchases - ending inventory?
