payback - IRR - PI - NPV

20. Comparing Investment Criteria – you are a senior manager at Poeing Aircraft and have been authorized to spend up to $400,000 for projects. The three projects you are considering have the following characteristics:

Project A : Initial investment of $280,000. Cash flow of $190,000 at year 1 and $170,000 at year 2. This is a plant expansion project, where the required rate of return is 10 percent.

Project B: Initial investment of $390,000. Cash flow of $270,000 at year 1 and $240,000 at year 2. This is a new product development project, where the required rate of return is 20 percent.

Project C: Initial investment of $230,000. Cash flow of $160,000 at year 1 and $190,000 at year 2. This is a market expansion project, where the required rate of return is 15 percent.

Assume the corporate discount rate is 10 percent.
Please offer your recommendations, backed by your analysis (payback, IRR, PI, NPV):

Answer:

The payback period is the time that it takes for the cumulative undiscounted cash inflows to equal the initial investment.

Project A :
Cumulative cash flows year 1 = $190,000                          =$190,000
Cumulative cash flows year2 = $190,000+$170,000            =$360,000
Payback period = 1 + ($90,000+$170,000)              =1.53 years.

Project B:
Cumulative cash flows year 1 = $270,000                               = $270,000
Cumulative cash flows year 2 = $270,000+$240,000           =$510,000

Payback period = 1 + ($120,000/$240,000)                             = 1.50 years

Project C:
Cumulative cash flows year 1 = $160,000                               =$160,000
Cumulative cash flows year2 = $160,000+$190,000            =$350,000

Payback period = 1 + ($70,000/$190,000)                               = 1.37 years.


IRR
IRR project A:
0 = -$280,000 + $190,000/(IRR) + $170,000/(IRR)2
IRR = 18.91

IRR project B:
0 = -$390,000 + $270,000/(IRR) + $240,000/(IRR)2
IRR = 20.36

IRR project C:
0=-$230,000 +$160,000/(IRR) +$190,000/(IRR)2
IRR = 32.10

IRR criteria implies accepting project C


The profitability index is the present value of all subsequent cash flows, divided by the initial investment. We need to discount the cash flows of each project by the required return of each project. The profitability index of each project is:

PI project A = ($190,000/1.10 +$170,000/1.102)/$280,000
PI = (172,727.27+140,495.87)/280,000
PI=1.12

PI project B = ($270,000/1.20 +$240,000/1.202)/$390,000
PI =($225,000+166,666.67)/390,000
PI=1.00
PI project C = ($160,000/1.15 +$190,000/1.152)/$230,000
PI=(139,130.43+143,939.39)/230,000
PI=1.23

The PI criteria implies accepting project C


We need to discount the cash flows of each project by the required return of each project.  The NPV of each project is:

NPV project  A:
NPV = -$280,000 + $190,000/1.10 +$170,000/1.102
NPV = $33,223.14

NPV project B:
NPV = -$390,000 +$270,000/1.20 +$240,000/1.202
NPV = $1,666.67

NPV project C:
NPV = -$230,000 +$160,000/1.15 + $190,000/1.152
NPV = $53,069.82

15. Profitability Index versus NPV – Hanmi Group, a consumer electronics conglomerate, is reviewing its annual budget in wireless technology. It is considering investments in three different technologies to develop wireless communication devices. Consider the following cash flows of the three independent projects of Hanmi. Assume the discount rate for Hanmi is 10 percent. Further, the Hanmi Group has only $15 million to invest in new projects this year.

a.   Based on the profitability index decision rule, rank these investment.
b.   Based on the NPV, rank these investment.
c.   Based on your findings in (a) and (b), what would you recommend to the CEO of Hanmi group and why?

Answer:

The profitability index (PI) is the PV of the future cash flows divided by the initial investment. The profitability index (PI) of each project is:
PICDMA = ($13,000,000/1.10 + $7,000,000/1.102 + $2,000,000/1.103) / $5,000,000
PICDMA = (11,818,181.82 + 5,785,123.97 + 1,502,629.60) / $5,000,000
PICDMA = 3.82

PIG4 = ($10,000,000/1.10 + $25,000,000/1.102 + $20,000,000/1.103) / $10,000,000
PIG4 = (9,090,909.09 + 20,661,157.02 + 15,026,296.02) / $10,000,000
PIG4 = 4.48

PIWF = ($10,000,000/1.10 +$20,000,000/1.102 +$50,000,000/1.103) / $15,000,000
PIWF = (9,090,909.09 + 16,528,925.62 + 37,565,740.05) / $15,000,000
PIWF = 4.21


The NPV of each project is:
NPVCDMA = -$5000,000 + $13,000,000/1.10 + $7,000,000/1.102 + $2,000,000/1.103 
NPVCDMA = $14,105,935.39 

NPVG4 = -$10,000,000 + $10,000,000/1.10 + $25,000,000/1.102 + $30,000,000/1.103 
NPVG4 = $34,778,362.13 

NPVWF = -$15,000,000 + $10,000,000/1.10 +$20,000,000/1.102 +$50,000,000/1.103 
NPVWF = $48,185,574.76 


NPVCDMA and G4 = $14,105,935.39 + $34,778,362.13 
NPVCDMA and G4 = $48,884,297.52

NPV versus IRR

11. NPV versus IRR – consider the following cash flows on two mutually exclusive projects for the Bahamas Recreation Corporation (BRC). Both projects requires an annual return of 14 percent.

year
Deepwater Fishing
New Submarine Ride
0
-$750000
-$2100000
1
310000
1200000
2
430000
760000
3
330000
850000

As financial analyst for BRC, you are asked the following questions:
a. If your decision rule is to accept the project with the greater IRR, which project should you choose?

b. Because you are fully aware of the IRR rule’s scale problem, you calculate the incremental IRR for the cash flows. Based on your computation, which project should you choose?

c. To be prudent, you compute the NPV for both projects. Which project should you choose? Is it consistent with the incremental IRR rule?

Answer:

a. The IRR is the interest rate that makes the NPV of the project equal to zero. So, the IRR for each project is:
Deepwater Fishing IRR:
0 = C0 + C1 /(1+IRR) + C2/(1+IRR)2  + C3/(1+IRR)3
0 = -$750,000 + 310,000/(1+IRR) + 430,000/(1+IRR)2 + 330,000/(1+IRR)3
IRR =

New Submarine Ride IRR:
0 = C0 + C1 /(1+IRR) + C2/(1+IRR)2  + C3/(1+IRR)3
0 = -$2,100,000 + 1,200,000/(1+IRR) + 760,000/(1+IRR)2 + 850,000/(1+IRR)3
IRR = 

a.  To calculate the incremental IRR, we subtract the smaller project cash flows from the larger project’s cash flows. In this case, we subtract the Deepwater Fishing Cash flows from the Sub Marine Ride cash flows. The incremental IRR is the IRR of these incremental cash flows.  So, the incremental cash flows of the sub marine ride are:
 

year 0
year 1
year 2
year 3
Submarine Ride
($2100000)
1200000
760000
850000
Deep water Fishing
($750000)
310000
430000
330000
Submarine - Fishing
($1350000)
890000
330000
520000






Setting the present value of these incremental cash flows equal to zero, we find the incremental IRR is:
0 = C0 + C1 /(1+IRR) + C2/(1+IRR)2  + C3/(1+IRR)3
0 = -$1350000 + 890000/(1+IRR)  + 330000/(1+IRR)2 + 520000/(1+IRR)3
Incremental IRR = 15.78%

 
a. The NPV is the sum of the present value of the cash flows from the project, so the NPV of each project will be:

Deepwater Fishing:
NPV = -$750,000 + $310,000/ 1.14 + $430,000/(1.14)2 +$330,000/(1.14)3
NPV = $75 548.08

Submarine Ride:
NPV = -$2,100,000 + $1,200,000/1.14 + $760,000/1.142 + $850,000/1.143
NPV = $111 169.72
