2、tal costsC NPV（净现值法）（1） Basic assumptions:cash outlay occurs in year 0 （now）.cash flows occur at the end of the year.if a cash flow occurs at the beginning of a year, it is assumed to occur at the end of the previous year.D IRR（内含报酬率法）（1）Basic principle: IRR is the cost of capital at which the NPV i
3、s zero, if the expected IRR is higher than a target rate of return; the project is financially worth undertaking.（2）Selection between IRR and NPV: when a choice has to be made between mutually exclusive projects, in such case the NPV should be selected, because higher NPV can maximize shareholders w
4、ealth.DefinitionThe discount rat which, when applied to the cash flows of a project, gives an NPV of zero.OrThe break-even interest rate for a project.It is the maximum rate of interest that you could afford to pay on a project without making a loss.FeaturesAdvantages -Takes into account the time va

6、s upon whether or not the project has even cash flows.Even cash flowsConsider an investment of 39.93m that generates net cash earnings of 10m for 5 yearsThe IRR is the discount rate that gives a NPV of zero. This means that the IRR is theRate that will discount five installments of 10m to a present
7、value of 39.93. This in turnMeans that the IRR is the discount rate for which the 5year annuity factor is 3.993. AThe projects IRR has been found via a cumulative discount factor （annuity factor） givenBy: Annuity factorat the IRR=for the life of the projectUneven cash flowsThese have to be found by
8、trial and error or by estimating using two present values.Where:A=lower rate chosen=NPV at rate AB=higher rate=NPV at rate BIt helps to get A and B as close to the true IRR as possible, but it doesnt matter whetherthe resultant NPVs are positive, negative or one of each.Some students prefer to use a
9、 common sense approach rather than a formula. Seeing by nowMuch NPV has fallen （fromto） as the discount rate has risen from A to B,They find how much more the discount rate needs to rise to bring the NPV to zero.Whether the formula is used or common sense, the calculation assumes a linear relationsh
10、ipBetween NPV and discount rate. In fact the relationship is not linear, hence the calculationIs only approximate and （unless you have been lucky when guessing which discount rates touse） you should not quote IRRs calculated in this way to many, not to any,decimal places unless the examiner asks you
11、.IRR of a perpetuityThe present value of a perpetuity is the annual cash flow divided by the discount rate（expressed as a decimal. From this it follows that:the IRR of a perpetuity =100Perpetuity: 永续年金Method of presentationA simple calculation such as those for Woods can be done on a single line. Fo
