54. The Option to Abandon: Example Traditional NPV analysis would indicate rejection of the project. NPV = = – $38.64 1.10 $287.50 – $300 + Expected Payoff = (0.50×$575) + (0.50×$0) = $287.50 = Expected Payoff Prob. Success × Successful Payoff + Prob. Failure × Failure Payoff
55. The Option to Abandon: Example The firm has two decisions to make: drill or not, abandon or stay. Traditional NPV analysis overlooks the option to abandon. Do not drill Drill 0 $ NPV 500 $ Failure Success: PV = $500 Sell the rig; salvage value = $250 Sit on rig; stare at empty hole: PV = $0.
56. The Option to Abandon: Example When we include the value of the option to abandon, the drilling project should proceed: NPV = = $75.00 1.10 $412.50 – $300 + Expected Payoff = (0.50×$575) + (0.50×$250) = $412.50 = Expected Payoff Prob. Success × Successful Payoff + Prob. Failure × Failure Payoff

Editor's Notes
Well, maybe you could get a “C” without studying.
If you don’t invest, the NPV = 0 even if you test first, because the cost of testing becomes a sunk cost. If you are so unwise as to invest in the face of a failed test, you incur lots of additional costs, but not much in the way of revenue, so you have a negative NPV as of date 1 of -$3,611. I didn’t think adding the calculations aided the pedagogy, so I left it off.
Note the irony of scenario 1: our workers are too sick to make the medicine.
