6. How would you evaluate the comments by Simpson’s supervisor about not using the IRR and about using the EAA? The supervisor is:
选项：
A.incorrect about both.
B.correct about IRR and incorrect about EAA.
C.incorrect about IRR and correct about EAA.
解释：
A is correct.
Both of the supervisor’s comments are incorrect. Because the Bayonne Pharma project is a conventional project (an outflow followed by inflows), the multiple IRR problem cannot occur. The EAA is preferred over the NPV when dealing with mutually exclusive projects with differing lives, a scenario which is not relevant for this decision. The Bayonne Pharma project is free-standing, so the NPV approach is appropriate.
老师，这个题目说的现金流1-5年， 6-12年的都不同（折旧只是到6年）， 也算是conventional cash flow么？
