A prоpоsed cаpitаl prоject is expected to produce operаting cash inflows of $114,000 per year for three years. At the beginning of the project, inventory will increase by $8,000, accounts receivable will increase by $11,000, and accounts payable will increase by $3,500. All net working capital will be recovered at the end of the project. The initial cost of fixed assets required for the project is $312,000. The fixed assets will be depreciated straight-line to a zero book value over the life of the project. No bonus depreciation will be taken. The fixed assets will be salvaged at the end of the project, creating an aftertax cash inflow of $37,000. What is the net present value of this project given a required return of 15.3 percent?
