Total annual net cash inflow = $1,500,000 ($300 x 5,000)
Expected period of revenue generation = 10 years
Discount rate = 10%
The PV annuity factor at 10% for 10 years = 6.145
The Present value of annuity of net cash inflow = $9,217,500 ($1,500,000 x 6.145).
The Present value of patent sale = $1,818,000 ($2,000,000 x 0.909).
