(10-2) IRR
A project has an initial cost of \$52,125, expected net cash inflows of \$12,000 per year for 8 years, and a cost of capital of 12%. What is the project’s NPV? (Hint: Begin by constructing a time line.) What’s the project’s IRR? NPV = Cash Flow in Period n/ (1 + Discount Rate)n

NPV = \$52,125 + 12,000/(1 +.12)8 = 4,846.60
12,000/(1 +.12)7 = 5,428.19
12,000/(1 +.12)6 = 6,079.58
12,000/(1 +.12)5 = 6,809.13
12,000/(1 +.12)4 = 7,626.21
12,000/(1 +.12)3 = 8,541.35
12,000/(1 +.12)2 = 9,566.33
12,000/(1 +.12)1 = 10,714.29
-52,125
Add each NPV to get NPV = \$7,486.68
IRR in excel – CF0 = -52,125, CF1-8= 12,000, IRR = 16%

(10-4) Profitability Index
Refer to previous problem. What the project’s profitability index? PI = 1 + NPV/Investment Required = 1 + \$7,486.68/\$52,125 = PI = 1.14

(10-6) What is the project’s discounted payback period?
Year 6 = \$-2,788.11, Year 7 = \$+2,640.08, so between year 6-7 2,788.11/5,428.19 = .514 = 6.51 years

(10-8) NPVs, IRRs, and MIRRs for Independent Projects
Edelman Engineering is considering including two pieces of equipment, a truck and an overhead pulley system, in this year’s capital budget. The projects are independent. The cash outlay for the truck is \$17,100 and that for the pulley system is \$22,430. The firm’s cost of capital is 14%. After-tax cash flows, including depreciation, are as follows:

YearTruckPulley
1\$5,100\$7,500
2\$5,100\$7,500
3\$5,100\$7,500
4\$5,100\$7,500
5\$5,100\$7,500

Calculate the IRR, the NPV, and the MIRR for each project, and indicate the correct accept–reject decision for each. TRUCK -

MIRR – using same cash flows as values and .14 as reinvestment rate, MIRR = 14.54% Accept.

In excel, using cash flows as values and .14 as reinvestment rate, MIRR = 17.19% Accept.

(10-10) Capital Budgeting Methods
Project S has a cost of \$10,000 and is expected to produce benefits (cash flows) of \$3,000 per year for 5 years. Project L costs \$25,000 and is expected to produce cash flows of \$7,400 per year for 5 years. Calculate the two projects’ NPVs, IRRs, MIRRs, and PIs, assuming a cost of capital of 12%. Which project would be selected, assuming they are mutually exclusive, using each ranking method? Which should actually be selected? Project S

NPV = -10,000 + 3,000 (1+.12)1 + 3,000 (1+.12)2 + 3,000 (1+.12)3 + 3,000 (1+.12)4 + 3,000 (1+.12)5 = -10,000 + 2,678.57143 + 2,135.3377 + 1,736.11111 + 1,906.55346 + 1,702.28219 = NPVs = \$814.33 IRRs in excel = 15.24%

MIRRs in excel = 13.77%
PI = 1 + NPV/Investment Required = 1+ 814.33/10,000 = PI = 1.081 Project L
NPV = -25,000 + 7,400 (1+.12)1 + 7,400(1+.12)2 + 7,400 (1+.12)3 + 7,400 (1+.12)4 + 7,400 (1+.12)5 = -25,000 + 6,607.14286 + 5,899.23469 + 5,267.16634 + 4,702.83187 + 4,198.96274 = NPVL = \$1,675.34 IRRL in excel = 14.67%

MIRRL in excel = 13.46%
PI = NPV/Investment Required = 1+ 1,675.34/25,000 = PI = 1.067 Using the NPV comparison, Project L appears to be the better investment. The IRR and MIRR are very close but make Project S appear to be the better investment. Using the Predictability Index, Project S appears to be more of a “bang for the buck”.

After discovering a new gold vein in the Colorado mountains, CTC Mining Corporation must decide whether to go ahead and develop the deposit. The most cost-effective method of mining gold is sulfuric acid extraction, a process that could result in environmental damage. Before proceeding with the extraction, CTC must spend...
