Build Corporation wants to purchase a new machine for $306,000. Management predicts that the machine can produce sales of $202,000 each year for the next 5 years. Expenses are expected to include direct materials, direct labor, and factory overhead (excluding depreciation) totaling $80,000 per year. The firm uses straight-line depreciation with no residual value for all depreciable assets. Build's combined income tax rate is 40%. Management requires a minimum after- tax rate of return of 10% on all investments. What is the present value payback period, rounded to one-tenth of a year? (Note: PV factors for 10% are as follows: year 1 = 0.909; year 2 = 0.826; year 3 = 0.751; year 4 = 0.683; year 5 = 0.621; the PV annuity factor for 10%, 5 years = 3.791. Assume that annual after-tax cash inflows occur at year-end.)
