老师讲单子经营法的时候考虑了税盾，这道题在根据Wd求D和E的时候为什么不考虑税盾呢

老师，您好。请问计提减值，对现金流没影响吗？计提减值，利润会减少，缴税也会减少，这样考虑是不是会对现金流有影响？

公司金融课程的视频总是一顿一顿的，有杂音

Current yield分母是flat price，为何呢？？这个yield有什么经济含义呢？？

您好，这道题的第二部解答里面，我不明白，为什么是N=-4，不是-5.因为不是说5个季度后才支付吗？The value today is (where FV is future value)PV = FVN(1 + r)–NPV = $133.33(1 + 0.015)–4PV = $125.62 ≈ $126.

这道题，只要会用计算器计算就可以，还是必须得掌握公式。我看cfa协会的题库里面全是这样解答的。

这道题，Q. An investment pays €300 annually for five years, with the first payment occurring today. The present value (PV) of the investment discounted at a 4% annual rate is closest to: €1,336. €1,389. €1,625. 只要会用金融计算器会算就可以了，还是必须得掌握公式B is correct, as shown in the following calculation for an annuity (A) due: PV=A[1−1(1+r)Nr](1+r), where A = €300, r = 0.04, and N = 5. PV=€300[1−1(1+.04)5.04](1.04) PV = €1,388.97, or ≈ €1,389.

为啥不直接用1.65

请问第一题怎么做

df=n-k k指什么
