A proposed new investment is considering a new three-year expansion project that requires an initial fixed asset investment of $120,000. The company spent $55,000 on research and development before launching the project. The investment is projected to generate sales of $250,000 each year. The variable cost and fixed cost combined are $150,000 each year. The project requires an initial investment in net working capital of $50,000, and the fixed asset will be depreciated to zero using straight-line depreciation and have a salvage value of $30,000 at the end of the project. The tax rate is 21%. The required return is 15 percent for this project.
