NET PRESENT VALUE (NPV) (Section 12.2)
To calculate the NPV, we find the present value of the individual cash flows and find the sum of those discounted cash flows. This value represents the value the project add to shareholder wealth.

Time period:01234Notice that the NPV function isn't really a Net present value. Instead, it is the present value of future cash flows. Thus, you specify only the future cash flows in the NPV function. To find the true NPV, you must add the time zero cash flow to the re

The NPV method of capital budgeting dictates that all independent projects that have positive NPV should accepted. The rationale behind that assertion arises from the idea that all such projects add wealth, and that should be the overall goal of the manag
INTERNAL RATE OF RETURN (IRR) (Section 12.2)
The internal rate of return is defined as the discount rate that equates the present value of a project's cash inflows to its outflows. In other words, the internal rate of return is the interest rate that forces NPV to zero. The calculation for IRR can

The IRR method of capital budgeting maintains that projects should be accepted if their IRR is greater than the cost of capital. Strict adherence to the IRR method would further dictate that mutually exclusive projects should be chosen on the basis of th
COMPARISON OF THE NPV AND IRR METHODS (Section 12.4)
NPV Profiles
NPV profiles graph the relationship between projects' NPVs and the cost of capital. To create NPV profiles for Projects S and L, we create data tables of NPV at different costs of capital.

Points about the graphs:
1. In Panel a, we see that if WACC < IRR, then NPV > 0, and vice versa.
2. Thus, for "normal and independent" projects, there can be no conflict between NPV and IRR rankings.
3. However, if we have mutually exclusive projects, conflicts can occur. In Panel b, we see that IRRS is
always greater than IRRL, but if WACC < 11.56%, then IRRL > IRRS, in which case a conflict occurs.
4. Summary: a. For normal, independent projects, conflicts can never occur, so either method can be used.
b. For mutually exclusive projects, if WACC > Crossover, no conflict, but if WACC < Crossover,
then there will be a conflict between NPV and IRR.
Previously, we had discussed that in some instances the NPV and IRR methods can give conflicting results. First, we should attempt to define what we see in this graph. Notice, that the two project profiles (S and L) intersect the x-axis at costs of capi
Looking further at the NPV profiles, we see that the two project profiles intersect at a point we shall call the crossover point. We observe that at costs of capital greater than the crossover point, the project with the greater IRR (Project S, in this c

IRR =Crossover rate =7.17%
The intuition behind the relationship between the NPV profile and the crossover rate is as follows: (1) Distant cash flows are heavily penalized by high discount rates--the denominator is (1+r)t, and it increases geometrically, hence gets very large at
When dealing with independent projects, the NPV and IRR methods will always yield the same accept/reject result. However, in the case of mutually exclusive projects, NPV and IRR can give conflicting results. One shortcoming of the internal rate of return
MULTIPLE IRRS (Section 12.5)
Because of the mathematics involved, it is possible for some (but not all) projects that have more than one change of signs in the set of cash flows to have more than one IRR. If you attempted to find the IRR with such a project using a financial calcul
Consider the case of Project M.
Project M:Year:012
CF:(1.6)10(10)
We will solve this IRR twice, the first time using the default guess of 10%, and the second time we will enter a guess of 300%. Notice, that the first IRR calculation is exactly as it was above.
IRR M 1 =25.0%
IRR M 2 =400%
The two solutions to this problem tell us that this project will have a positive NPV for all costs of capital between 25% and 400%. We illustrate this point by creating a data table and a graph of the project NPVs.

MODIFIED INTERNAL RATE OF RETURN (MIRR) (Section 12.6)
The modified internal rate of return is the discount rate that causes a project's cost (or cash outflows) to equal the present value of the project's terminal value. The terminal value is defined as the sum of the future values of the 'project's cash inf

The advantage of using the MIRR, relative to the IRR, is that the MIRR assumes that cash flows received are reinvested at the cost of capital, not the IRR. Since reinvestment at the cost of capital is more likely, the MIRR is a better indicator of a proj
Note that if negative cash flows occur in years beyond Year 1, those cash flows would be discounted at the cost of capital and added to the Year 0 cost to find the total PV of costs. If both positive and negative flows occurred in some year, the negativ
Also note that Excel's MIRR function allows for discounting and reinvestment to occur at different rates. Generally, MIRR is defined as reinvestment at the WACC, though Excel allows the calculation of a special MIRR where reinvestment occurs at a differe
Finally, it is stated in the text, when the IRR versus the NPV is discussed, that the NPV is superior because (1) the NPV assumes that cash flows are reinvested at the cost of capital whereas the IRR assumes reinvestment at the IRR, and (2) it is more lik

NPV$0.00Thus, if compounding is at the IRR, NPV is zero. Since the
definition of IRR is the rate at which NPV = 0, this demonstrates
that the IRR assumes reinvestment at the IRR.
PROFITABILITY INDEX (PI) (Section 12.7)
The profitability index is the present value of all future cash flows divided by the intial cost. It measures the PV per dollar of investment.
For project S:
PI(S) =PV of future cash flowsInitial cost
PI(S) =$1,078.82$1,000.00
PI(S) =1.079

PAYBACK METHODS (Section 12.8)
Payback Period
The payback period is defined as the expected number of years required to recover the investment, and it was the first formal method used to evaluate capital budgeting projects. First, we identify the year in which the cumulative cash inflows exceed the

Discounted Payback Period
Discounted payback period uses the project's cost of capital to discount the expected cash flows. The calculation of discounted payback period is identical to the calculation of regular payback period, except you must base the calculation on a new row of

The inherent problem with both paybacks is that they ignore cash flows that occur after the payback period mark. While the discounted method accounts for timing issues (to some extent), it still falls short of fully analyzing projects. However, all else
SPECIAL APPLICATIONS OF CASH FLOW EVALUATION (Section 12.11)
PROJECTS WITH UNEQUAL LIVES
If two mutually exclusive projects have different lives, and if the projects can be repeated, then it is necessary to deal explicitly with those unequal lives. We use the replacement chain (or common life) approach. This procedure compares projects of un
r =11.5%

NPVFF =$9,281IRRFF =25.2%
On the basis of this extended analysis, it is clear that Project F is the better of the two investments (with both the NPV and IRR methods).
Equivalent Annual Annuity (EAA) Approach
Here are the steps in the EAA approach.
1.Find the NPV of each project over its initial life (we already did this in our previous analysis).
NPVC=7,165
NPVF=5,391
2.Convert the NPV into an annuity payment with a life equal to the life of the project.
EEAC=1,718Note: we used the Function Wizard for the PMT function.
EEAF=2,225
Project F has a higher EEA, so it is a better project.
ECONOMIC LIFE VS. PHYSICAL LIFE
Sometimes an asset has a physical life that is greater than its economic life. Consider the following asset which has a physical life of three years. During its life, the asset will generate operating cash flows. However, the project could be terminate

0($4,800)$4,800
1$2,000$3,000
2$2,000$1,650
3$1,750$0
The cost of capital is 10%. If the asset is operated for the entire three years of its life, its NPV is:
3-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value
=($4,800.00)+$4,785.88+$0.00
3-Year NPV =($14.12)
The asset has a negative NPV if it is kept for three years. But even though the asset will last three years, it might be better to operate the asset for either one or two years, and then salvage it.
2-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value

Points about the graphs:
1. In Panel a, we see that if WACC < IRR, then NPV > 0, and vice versa.
2. Thus, for "normal and independent" projects, there can be no conflict between NPV and IRR rankings.
4. Summary: a. For normal, independent projects, conflicts can never occur, so either method can be used.
b. For mutually exclusive projects, if WACC > Crossover, no conflict, but if WACC < Crossover,
then there will be a conflict between NPV and IRR.
Previously, we had discussed that in some instances the NPV and IRR methods can give conflicting results. First, we should attempt to define what we see in this graph. Notice, that the two project profiles (S and L) intersect the x-axis at costs of capi
Looking further at the NPV profiles, we see that the two project profiles intersect at a point we shall call the crossover point. We observe that at costs of capital greater than the crossover point, the project with the greater IRR (Project S, in this c

When dealing with independent projects, the NPV and IRR methods will always yield the same accept/reject result. However, in the case of mutually exclusive projects, NPV and IRR can give conflicting results. One shortcoming of the internal rate of return
Because of the mathematics involved, it is possible for some (but not all) projects that have more than one change of signs in the set of cash flows to have more than one IRR. If you attempted to find the IRR with such a project using a financial calcul
Consider the case of Project M.

We will solve this IRR twice, the first time using the default guess of 10%, and the second time we will enter a guess of 300%. Notice, that the first IRR calculation is exactly as it was above.

The two solutions to this problem tell us that this project will have a positive NPV for all costs of capital between 25% and 400%. We illustrate this point by creating a data table and a graph of the project NPVs.

The advantage of using the MIRR, relative to the IRR, is that the MIRR assumes that cash flows received are reinvested at the cost of capital, not the IRR. Since reinvestment at the cost of capital is more likely, the MIRR is a better indicator of a proj
Note that if negative cash flows occur in years beyond Year 1, those cash flows would be discounted at the cost of capital and added to the Year 0 cost to find the total PV of costs. If both positive and negative flows occurred in some year, the negativ
Also note that Excel's MIRR function allows for discounting and reinvestment to occur at different rates. Generally, MIRR is defined as reinvestment at the WACC, though Excel allows the calculation of a special MIRR where reinvestment occurs at a differe
Finally, it is stated in the text, when the IRR versus the NPV is discussed, that the NPV is superior because (1) the NPV assumes that cash flows are reinvested at the cost of capital whereas the IRR assumes reinvestment at the IRR, and (2) it is more lik

that the IRR assumes reinvestment at the IRR.

Payback Period
The payback period is defined as the expected number of years required to recover the investment, and it was the first formal method used to evaluate capital budgeting projects. First, we identify the year in which the cumulative cash inflows exceed the

The inherent problem with both paybacks is that they ignore cash flows that occur after the payback period mark. While the discounted method accounts for timing issues (to some extent), it still falls short of fully analyzing projects. However, all else
PROJECTS WITH UNEQUAL LIVES

On the basis of this extended analysis, it is clear that Project F is the better of the two investments (with both the NPV and IRR methods).
Equivalent Annual Annuity (EAA) Approach
Here are the steps in the EAA approach.
1.Find the NPV of each project over its initial life (we already did this in our previous analysis).
NPVC=7,165
NPVF=5,391
2.Convert the NPV into an annuity payment with a life equal to the life of the project.
EEAC=1,718Note: we used the Function Wizard for the PMT function.
EEAF=2,225
Project F has a higher EEA, so it is a better project.
ECONOMIC LIFE VS. PHYSICAL LIFE
Sometimes an asset has a physical life that is greater than its economic life. Consider the following asset which has a physical life of three years. During its life, the asset will generate operating cash flows. However, the project could be terminate

0($4,800)$4,800
1$2,000$3,000
2$2,000$1,650
3$1,750$0
The cost of capital is 10%. If the asset is operated for the entire three years of its life, its NPV is:
3-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value
=($4,800.00)+$4,785.88+$0.00
3-Year NPV =($14.12)
The asset has a negative NPV if it is kept for three years. But even though the asset will last three years, it might be better to operate the asset for either one or two years, and then salvage it.
2-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value

4. Summary: a. For normal, independent projects, conflicts can never occur, so either method can be used.
b. For mutually exclusive projects, if WACC > Crossover, no conflict, but if WACC < Crossover,
then there will be a conflict between NPV and IRR.
Previously, we had discussed that in some instances the NPV and IRR methods can give conflicting results. First, we should attempt to define what we see in this graph. Notice, that the two project profiles (S and L) intersect the x-axis at costs of capi
Looking further at the NPV profiles, we see that the two project profiles intersect at a point we shall call the crossover point. We observe that at costs of capital greater than the crossover point, the project with the greater IRR (Project S, in this c

The intuition behind the relationship between the NPV profile and the crossover rate is as follows: (1) Distant cash flows are heavily penalized by high discount rates--the denominator is (1+r)t, and it increases geometrically, hence gets very large at
When dealing with independent projects, the NPV and IRR methods will always yield the same accept/reject result. However, in the case of mutually exclusive projects, NPV and IRR can give conflicting results. One shortcoming of the internal rate of return
MULTIPLE IRRS (Section 12.5)
Because of the mathematics involved, it is possible for some (but not all) projects that have more than one change of signs in the set of cash flows to have more than one IRR. If you attempted to find the IRR with such a project using a financial calcul
Consider the case of Project M.
Project M:Year:012
CF:(1.6)10(10)
We will solve this IRR twice, the first time using the default guess of 10%, and the second time we will enter a guess of 300%. Notice, that the first IRR calculation is exactly as it was above.
IRR M 1 =25.0%
IRR M 2 =400%
The two solutions to this problem tell us that this project will have a positive NPV for all costs of capital between 25% and 400%. We illustrate this point by creating a data table and a graph of the project NPVs.

MODIFIED INTERNAL RATE OF RETURN (MIRR) (Section 12.6)
The modified internal rate of return is the discount rate that causes a project's cost (or cash outflows) to equal the present value of the project's terminal value. The terminal value is defined as the sum of the future values of the 'project's cash inf

The advantage of using the MIRR, relative to the IRR, is that the MIRR assumes that cash flows received are reinvested at the cost of capital, not the IRR. Since reinvestment at the cost of capital is more likely, the MIRR is a better indicator of a proj
Note that if negative cash flows occur in years beyond Year 1, those cash flows would be discounted at the cost of capital and added to the Year 0 cost to find the total PV of costs. If both positive and negative flows occurred in some year, the negativ

Finally, it is stated in the text, when the IRR versus the NPV is discussed, that the NPV is superior because (1) the NPV assumes that cash flows are reinvested at the cost of capital whereas the IRR assumes reinvestment at the IRR, and (2) it is more lik

that the IRR assumes reinvestment at the IRR.
PROFITABILITY INDEX (PI) (Section 12.7)
The profitability index is the present value of all future cash flows divided by the intial cost. It measures the PV per dollar of investment.
For project S:
PI(S) =PV of future cash flowsInitial cost
PI(S) =$1,078.82$1,000.00

PAYBACK METHODS (Section 12.8)
Payback Period
The payback period is defined as the expected number of years required to recover the investment, and it was the first formal method used to evaluate capital budgeting projects. First, we identify the year in which the cumulative cash inflows exceed the

Discounted Payback Period
Discounted payback period uses the project's cost of capital to discount the expected cash flows. The calculation of discounted payback period is identical to the calculation of regular payback period, except you must base the calculation on a new row of

SPECIAL APPLICATIONS OF CASH FLOW EVALUATION (Section 12.11)
PROJECTS WITH UNEQUAL LIVES
If two mutually exclusive projects have different lives, and if the projects can be repeated, then it is necessary to deal explicitly with those unequal lives. We use the replacement chain (or common life) approach. This procedure compares projects of un

On the basis of this extended analysis, it is clear that Project F is the better of the two investments (with both the NPV and IRR methods).
Equivalent Annual Annuity (EAA) Approach
Here are the steps in the EAA approach.
1.Find the NPV of each project over its initial life (we already did this in our previous analysis).
NPVC=7,165
NPVF=5,391
2.Convert the NPV into an annuity payment with a life equal to the life of the project.
EEAC=1,718Note: we used the Function Wizard for the PMT function.
EEAF=2,225
Project F has a higher EEA, so it is a better project.
ECONOMIC LIFE VS. PHYSICAL LIFE
Sometimes an asset has a physical life that is greater than its economic life. Consider the following asset which has a physical life of three years. During its life, the asset will generate operating cash flows. However, the project could be terminate

0($4,800)$4,800
1$2,000$3,000
2$2,000$1,650
3$1,750$0
The cost of capital is 10%. If the asset is operated for the entire three years of its life, its NPV is:
3-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value
=($4,800.00)+$4,785.88+$0.00
3-Year NPV =($14.12)
The asset has a negative NPV if it is kept for three years. But even though the asset will last three years, it might be better to operate the asset for either one or two years, and then salvage it.
2-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value

Points about the graphs:
1. In Panel a, we see that if WACC < IRR, then NPV > 0, and vice versa.
2. Thus, for "normal and independent" projects, there can be no conflict between NPV and IRR rankings.
4. Summary: a. For normal, independent projects, conflicts can never occur, so either method can be used.
b. For mutually exclusive projects, if WACC > Crossover, no conflict, but if WACC < Crossover,
then there will be a conflict between NPV and IRR.
Previously, we had discussed that in some instances the NPV and IRR methods can give conflicting results. First, we should attempt to define what we see in this graph. Notice, that the two project profiles (S and L) intersect the x-axis at costs of capi
Looking further at the NPV profiles, we see that the two project profiles intersect at a point we shall call the crossover point. We observe that at costs of capital greater than the crossover point, the project with the greater IRR (Project S, in this c

When dealing with independent projects, the NPV and IRR methods will always yield the same accept/reject result. However, in the case of mutually exclusive projects, NPV and IRR can give conflicting results. One shortcoming of the internal rate of return
Because of the mathematics involved, it is possible for some (but not all) projects that have more than one change of signs in the set of cash flows to have more than one IRR. If you attempted to find the IRR with such a project using a financial calcul
Consider the case of Project M.

We will solve this IRR twice, the first time using the default guess of 10%, and the second time we will enter a guess of 300%. Notice, that the first IRR calculation is exactly as it was above.

The two solutions to this problem tell us that this project will have a positive NPV for all costs of capital between 25% and 400%. We illustrate this point by creating a data table and a graph of the project NPVs.

Payback Period
The payback period is defined as the expected number of years required to recover the investment, and it was the first formal method used to evaluate capital budgeting projects. First, we identify the year in which the cumulative cash inflows exceed the

The inherent problem with both paybacks is that they ignore cash flows that occur after the payback period mark. While the discounted method accounts for timing issues (to some extent), it still falls short of fully analyzing projects. However, all else
PROJECTS WITH UNEQUAL LIVES
If two mutually exclusive projects have different lives, and if the projects can be repeated, then it is necessary to deal explicitly with those unequal lives. We use the replacement chain (or common life) approach. This procedure compares projects of un

On the basis of this extended analysis, it is clear that Project F is the better of the two investments (with both the NPV and IRR methods).
Equivalent Annual Annuity (EAA) Approach
Here are the steps in the EAA approach.
1.Find the NPV of each project over its initial life (we already did this in our previous analysis).
NPVC=7,165
NPVF=5,391
2.Convert the NPV into an annuity payment with a life equal to the life of the project.
EEAC=1,718Note: we used the Function Wizard for the PMT function.
EEAF=2,225
Project F has a higher EEA, so it is a better project.
ECONOMIC LIFE VS. PHYSICAL LIFE
Sometimes an asset has a physical life that is greater than its economic life. Consider the following asset which has a physical life of three years. During its life, the asset will generate operating cash flows. However, the project could be terminate

0($4,800)$4,800
1$2,000$3,000
2$2,000$1,650
3$1,750$0
The cost of capital is 10%. If the asset is operated for the entire three years of its life, its NPV is:
3-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value
=($4,800.00)+$4,785.88+$0.00
3-Year NPV =($14.12)
The asset has a negative NPV if it is kept for three years. But even though the asset will last three years, it might be better to operate the asset for either one or two years, and then salvage it.
2-Year NPV =Intial Cost+PV of Operating Cash Flow+PV of Salvage Value

INTERNAL RATE OF RETURN (IRR) (Section 12.2)
The internal rate of return is defined as the discount rate that equates the present value of a project's cash inflows to its outflows. In other words, the internal rate of return is the interest rate that forces NPV to zero. The calculation for IRR can

Points about the graphs:
1. In Panel a, we see that if WACC < IRR, then NPV > 0, and vice versa.
2. Thus, for "normal and independent" projects, there can be no conflict between NPV and IRR rankings.
3. However, if we have mutually exclusive projects, conflicts can occur. In Panel b, we see that IRRS is
always greater than IRRL, but if WACC < 11.56%, then IRRL > IRRS, in which case a conflict occurs.
4. Summary: a. For normal, independent projects, conflicts can never occur, so either method can be used.
b. For mutually exclusive projects, if WACC > Crossover, no conflict, but if WACC < Crossover,
then there will be a conflict between NPV and IRR.
Previously, we had discussed that in some instances the NPV and IRR methods can give conflicting results. First, we should attempt to define what we see in this graph. Notice, that the two project profiles (S and L) intersect the x-axis at costs of capi

Consider the case of Project M.

The two solutions to this problem tell us that this project will have a positive NPV for all costs of capital between 25% and 400%. We illustrate this point by creating a data table and a graph of the project NPVs.

PV outflows-$1,000.00Terminal Value:1,579.5
PV of TV$1,078.82
NPV$78.82Thus, we see that the NPV is consistent with reinvestment at WACC.
Now repeat the process using the IRR as the discount rate.

PV outflows-$1,000.00Terminal Value:1,718.1
PV of TV$1,000.00
NPV$0.00Thus, if compounding is at the IRR, NPV is zero. Since the
definition of IRR is the rate at which NPV = 0, this demonstrates
that the IRR assumes reinvestment at the IRR.
PROFITABILITY INDEX (PI) (Section 12.7)
The profitability index is the present value of all future cash flows divided by the intial cost. It measures the PV per dollar of investment.
For project S:
PI(S) =PV of future cash flowsInitial cost
PI(S) =$1,078.82$1,000.00
PI(S) =1.079
For project L:
PI(L) =PV of future cash flowsInitial cost
PI(L) =$1,049.18$1,000.00
PI(L) =1.049
PAYBACK METHODS (Section 12.8)
Payback Period
The payback period is defined as the expected number of years required to recover the investment, and it was the first formal method used to evaluate capital budgeting projects. First, we identify the year in which the cumulative cash inflows exceed the

Discounted Payback Period
Discounted payback period uses the project's cost of capital to discount the expected cash flows. The calculation of discounted payback period is identical to the calculation of regular payback period, except you must base the calculation on a new row of

The inherent problem with both paybacks is that they ignore cash flows that occur after the payback period mark. While the discounted method accounts for timing issues (to some extent), it still falls short of fully analyzing projects. However, all else
SPECIAL APPLICATIONS OF CASH FLOW EVALUATION (Section 12.11)
PROJECTS WITH UNEQUAL LIVES
If two mutually exclusive projects have different lives, and if the projects can be repeated, then it is necessary to deal explicitly with those unequal lives. We use the replacement chain (or common life) approach. This procedure compares projects of un
