1. Consider the investment projects given in the table below. | |||||||
Net Cash Flow of Project | |||||||
Year | A | B | C | ||||
0 | ($1,500) | ($5,000) | ($2,200) | ||||
1 | $700 | $3,000 | $1,600 | ||||
2 | $2,500 | $4,500 | $2,600 | ||||
a. Compute the IRR for each project. | |||||||
b. On the basis of IRR criteria, if all three projects are mutually exclusive | |||||||
investments, which project should be selected at 15% MARR? | |||||||
c. Create a set of decision statements for varying MARR from 0% to 60%. | |||||||
(Do not provide statements if the result will be a loss |
a) r = IRR
For A
initial investment = 1500
CF 1 = 700
CF 2 = 2500
Assume NPV = 0
NPV = [ CF1 / (1+r) ] + [ (CF2 / (1+r)2] - initial investment
0 =[ 700/ (1+r) ] + [ 2500 / (1+r)2 ] - 1500
Multiply with (1+r)2 on both sides
1500 (1+r)2 = 700 (1+r) + 2500
15 (1+2r + r2) = 7 + 7r + 25
15 r2 + 23r - 17 = 0
r = 0.545
IRR = 54.5%
For B
initial investment = 5000
CF 1 = 3000
CF 2 = 4500
Assume NPV = 0
NPV = [ CF1 / (1+r) ] + [ (CF2 / (1+r)2] - initial investment
0 =[ 3000/ (1+r) ] + [ 4500 / (1+r)2 ] - 5000
Multiply with (1+r)2 on both sides
5000 (1+r)2 = 3000 (1+r) + 4500
50 (1+2r + r2) = 30 + 30r + 45
50 r2 + 70r - 25 = 0
r = 0.295
IRR = 29.5%
For C
initial investment =2200
CF 1 = 1600
CF 2 = 2600
Assume NPV = 0
NPV = [ CF1 / (1+r) ] + [ (CF2 / (1+r)2] - initial investment
0 =[ 1600/ (1+r) ] + [ 2600 / (1+r)2 ] - 2200
Multiply with (1+r)2 on both sides
2200 (1+r)2 = 1600 (1+r) + 2600
22 (1+2r + r2) = 16 + 16r + 26
22 r2 + 28r - 20= 0
r = 0.5096
IRR = 50.96%
b) IF the IRR > or = MARR
than the project should be selected
All the should projects should be selected as their IRR value greater than MAR value of 15%
