And, to evaluate this project, he needs to estimate the cost of capital that can be used to discount future incremental cash flows from this investment. The appropriate discount rate for this project would be the overall cost of capital of Jason Enterprises. The company has $198 million in debt. It has 36 million shares outstanding and the stock price is $21 per share. Jason could borrow at 6.6%. The risk-free rate is 5%, and the market risk premium is 4%. The stock has a beta of 1.39. The applicable tax rate is 17%.
