1Finance - Pedro Barroso

Sensitivity, Scenario, and Break-Even

• Allows us to look behind the NPV number to see how stable our estimates are

• When working with spreadsheets, try to build your model so that you can adjust variables in a single cell and have the NPV calculations update accordingly

2Finance - Pedro Barroso

Example• Projected annual sales: 1,800 ton• Price: 5 per ton• Variable costs: 3 per ton• Fixed costs: 1,000 per year• Initial investment (fixed assets) of 6,000 with life of 3

years and salvage value of 0• No investment in working capital• Inflation: 0%• Discount rate: 8%• Tax rate: 30% (losses can be offset elsewhere in firm)

Break-Even Analysis: Example• Another way to examine variability in our forecasts• What is the minimum (maximum) input value such that NPV is

at least zero (IRR = discount rate)?• Break-even analysis:

– Annual sales (min): 1,734 ton– Price (min): 4.927– Variable cost (max): 3.073– Fixed cost (max): 1,131

Real Options

• One of the fundamental insights of modern finance theory is that options have value

• Because corporations make decisions in a dynamic environment, they have options that should be considered in project valuation

• Traditional NPV does not include options value (always zero or positive)

9Finance - Pedro Barroso

Real Options• Option to Expand– Has value if demand turns out to be higher than

expected

• Option to Abandon– Has value if demand turns out to be lower than

expected

• Option to Delay– Has value if the underlying variables are changing

with a favorable trend

10Finance - Pedro Barroso

Discounted CF and Options• We can calculate the market value of a project as the sum of the

NPV of the project without options and the value of the managerial options implicit in the project:

NPV + Options

Example: Comparing a specialized machine versus a more versatile machine; if they both cost about the same and last the same amount of time, more versatile machine is more valuable because it comes with options

11Finance - Pedro Barroso

Option to Abandon: Example• Suppose we are drilling an oil well. The drilling rig

costs $300 today, and in one year the well is either a success or a failure

• Outcomes are equally likely. Discount rate is 10%

• PV of the successful payoff at time one is $575

• PV of the unsuccessful payoff at time one is $0

Option to Abandon: Example

Traditional NPV would indicate rejection of project:

Sell the rig; salvage value

Sit on rig; stare at empty hole:

Traditional NPV analysis overlooks the option to abandon.

• When we include the value of the option to abandon, drilling project should proceed:

Option to Delay: Example

• Project can be undertaken in any of the next 4 years; discount rate is 10%

• Regardless when the time the project is launched it generate a cash flow of 2,500 forever

• NPV at the time of launch steadily rises; best time to launch the project is in year 2 (highest NPV when judged today)

Decision Trees

• Allow us to graphically represent the alternatives available to us in each period and the likely consequences of our actions

• This graphical representation helps to identify the best course of action

Decision Trees

Squares represent decisions to be made (work backward). Circles represent

receipt of information, e.g., a test score.

The lines leading away from the squares represent the alternatives

Decision Tree: Example• Stewart Pharmaceuticals Corp is considering investing in the

development of a drug that cures the common cold• A corporate planning group has recommended that the firm

should go ahead with the test and development phase• This preliminary phase will last one year and cost $1,000; There

is a 60% chance that tests will prove successful• If initial tests are successful, Stewart Pharmaceuticals can go

ahead with full-scale production. This investment phase will cost $1,600. Production will occur over the following 4 years with a cash flow of $1,588

• If initial tests are unsuccessful, annual cash flow is $475.9• Discount rate is 10%

NPV = 3,433.75

Decision Tree: Example• Decision to invest:

– Test successuful (probability 60%): Invest as NPV = 3,433.75 > 0– Test unsuccessuful (probability 40%): Not invest as NPV = -91.46 < 0

• Decision to test:– Expected payoff at year 1:

– NPV of testing at year 0:

– NPV is positive, so we should make the test
