Hammer Corporation wants to purchase a new machine for $285,000. Management predicts that the machine will produce sales of $290,000 each year for the next 5 years. Expenses are expected to include direct materials, direct labor, and factory overhead (excluding depreciation) totaling $89,000 per year. The firm uses straight-line depreciation with an assumed residual (salvage) value of $50,000. Hammer's combined income tax rate, t, is 40%. Management requires a minimum after-tax rate of return of 10% on all investments. What is the estimated net present value (NPV) of the proposed investment (rounded to the nearest hundred dollars)? (The PV annuity factor for 10%, 5 years, is 3.791 and for 4 years it is 3.17. The present value $1 factor for 10%, 5 years, is 0.621.) Assume that after-tax cash inflows occur at year-end. Multiple Choice $243,500. $274,500. $293,700. $306,700. $264,700
