IntegrativeDetermining relevant cash flows Lombard Company is contemplating the purchase of a new high-speed widget grinder to replace the existing grinder. The existing grinder was purchased 2 years ago at an installed cost of $55,500; it was being depreciated under MACRS using a 5-year recovery period. The existing grinder is expected to have a usable life of 5 more years. The new grinder costs $105,900 and requires $5,500 in installation costs; it has a 5-year usable life and would be depreciated under MACRS using a 5-year recovery period. Lombard can currently sell the existing grinder for $69,800 without incurring any removal or cleanup costs. To support the increased business resulting from purchase of the new grinder, accounts receivable would increase by $40,600, inventories by $29,100, and accounts payable by $57,200. At the end of 5 years, the existing grinder is expected to have a market value of zero; the new grinder would be sold to net $29,200 after removal and cleanup costs and before taxes. The firm pays taxes at a rate of 40% on both ordinary income and capital gains. The estimated profits before depreciation and taxes over the 5 years for both the new and the existing grinder are shown in the following table. (Table 3.2 on page 100 contains the applicable MACRS depreciation percentages.)
