ObtainingInputsforPatentValuation
Input Estimation Process
1. Value of the Underlying Asset • Present Value of Cash Inflows from taking projectnow
• This will be noisy, but that adds value.2. Variance in value of underlying asset • Variance in cash flows of similar assets or firms
• Variance in present value from capital budgetingsimulation.
3. Exercise Price on Option • Option is exercised when investment is made.• Cost of making investment on the project ; assumed
to be constant in present value dollars.4. Expiration of the Option • Life of the patent
5. Dividend Yield • Cost of delay• Each year of delay translates into one less year of
value-creating cashflowsAnnual cost of delay = 1
