Pitfall! Activision, 1982
10 NPV Pitfall #1: Formula error
Presented at the 2013 ICEAA Professional Development & Training Workshop - www.iceaaonline.com Which is the correct formula to determine year t’s Discount Factor? • 1/(1+r)t • (1‐r)t (where r is the discount rate) There is a difference:
r = 10% Sum (PV) t = 1 2 3 4 5 6 7 8 9 10 1/(1+r)t 6.14 0.909 0.826 0.751 0.683 0.621 0.564 0.513 0.467 0.424 0.386 (1‐r)t 5.86 0.900 0.810 0.729 0.656 0.590 0.531 0.478 0.430 0.387 0.349 If your initial investment was $6, (1‐r)t would have resulted in negative NPV and a decision to reject the investment!
11 NPV Pitfall #2: Inflation Treatment

12 NPV Pitfall #2: Inflation Treatment
Presented at the 2013 ICEAA Professional Development & Training Workshop - www.iceaaonline.com • Not correct! • The example discounts a real (no inflation) cash flow with a discount factor that includes an inflation assumption (nominal) • Two ways to approach this correctly: • 1) Convert cash flow to nominal and compute PV using the nominal discount rate: • Convert cash flow to nominal: $100 x (1.02) = $102. • Discount nominal cash flow: $102/1.09 = $93.58 • 2) Convert discount rate to real and discount the real cash flow: • Convert discount rate (solve for r) • (1+r)*(1.02) = (1.09) • r = 1.09/1.02 –1 = 6.8627% • Discount real cash flow • $100/1.068627 = $93.58
13 NPV Pitfall #3: Excel’s “=NPV()”
Presented at the 2013 ICEAA Professional Development & Training Workshop - www.iceaaonline.com • Microsoft Excel’s function NPV() is really just a Present Value function, returning the value of a cash flow stream at time t = 0 • The “netting” of any initial investment (t = 0) must be programmed in by the user
14 NPV Pitfall #3: Excel’s “=NPV()”
Presented at the 2013 ICEAA Professional Development & Training Workshop - www.iceaaonline.com
Example
The first calculation includes the initial investment in the NPV function, incorrectly discounting it as a result
The second calculation uses the NPV function only to discount the cash flows starting at time t = 1
In other words, “=NPV()” should only be used with future cash flows

19 Case Study: Suggested Critiques
Presented at the 2013 ICEAA Professional Development & Training Workshop - www.iceaaonline.com
"Preliminary Engineering" is a sunk cost; not a relevant cash flow and should be omitted
