NO.PZ2016021706000003问题如下Megan, a stunt learning corporate finanthis year, wrote wn something about NPV anIRR on her notebook.Statement 1: The IRR is the scount rate thmakes the project's present value of cash inflows equto the present value of cash outflows.Statement 2: Analyst shouluse the IRRs to selethe project, if the IRR methogives a fferent ranking result from the NPV methoStatement 3: The NPV is the present value of the future after-tcash flows minus the investment outlay.Statement 4: If IRR the requirerate of return, accept the project.Whiof Megan's statements are correct? A.Statement 1, 3 B.Statement 1, 3, 4 C.Statement 2, 4 B is correct.Statement 2 is incorrect, because the NPV methoshoulselecteif NPV anIRR give conflicting cisions. Statement 1,3,4 are all correct.这里强调了after tax得，我有点纠结，npv计算里，么有刻意强调过税前税后好像。这题因为答案得设置，3基本是不用看得，但是如果是1，4和1，3，4对比我就有点纠结。请问有明确得定义说npv是税后得吗？那么irr也是税后？计算npv得时候，没有说税前税后，都要按税后算吗
NO.PZ2016021706000003 Statement 1, 3, 4 Statement 2, 4 B is correct. Statement 2 is incorrect, because the NPV methoshoulselecteif NPV anIRR give conflicting cisions. Statement 1,3,4 are all correct. statment4太不严谨 即使IRR>r若npv<0就不能投 考试时这么出题怎么判断好呢
NO.PZ2016021706000003 我记得在这套题对应的讲义里说过书上觉得irr更好，因为irr更好理解。所以在考试的时候我们应该用书上这个结论吗？还是说就是npv更好呢
NO.PZ2016021706000003 Statement 1, 3, 4 Statement 2, 4 B is correct. Statement 2 is incorrect, because the NPV methoshoulselecteif NPV anIRR give conflicting cisions. Statement 1,3,4 are all correct. 题目所说表示npv>0，不代表项目一定可接受啊
老师 S3里 future after t怎么理解？
