Chapter 12 – Strategy and the Analysis of Capital Investments
12-37 NPV; Sensitivity Analysis (20 minutes)
1. NPV of proposed investment,15-year project life:
PV of after-tax cash inflows = $600,000 × 6.142 = $3,685,200
Initial investment outlay = 3,500,000
2. We are given annual after-tax cash inflows of $600,000 and an initial
investment outlay of $3,500,000. To generate an IRR of exactly 14.00%, the
following must hold:
PV of Future Cash Inflows = Initial Investment Outlay
$600,000 × An,14% = $3,500,000
Thus, we need to solve for the particular n that balances the preceding
equation. An, 14% = $3,500,000 ÷ $600,000 = 5.833. This annuity factor, at 14%,
In the present case, the annuity factor = 5.83333 and r = 0.14. Thus, we have
5.83333 = [1 ÷ 0.14] × [1 – [1 ÷ (1.14)n]]
(2) Next, subtract 1 from both sides, to yield:
-0.1833338 = – 1 ÷ (1.14)n
