You are a financial analyst at the Humongous Project Company (HPC). Four years ago, HPC purchased a machine at an installed cost of $70,000; the machine is being depreciated using MACRS with a 5-year recovery period. The machine has six years of useful life remaining and could be sold today for $403,000 after removal and cleanup costs.

A new, more efficient machine can be purchased for $280,000. The new machine would cost $10,000 to install and would have a useful life of 6 years; it would be depreciated using a 5-year MACRS depreciation recovery schedule. At the end of the six years, it would have an estimated salvage value of $60,000.

Because of the increased output of the new machine, the firms sales would rise, with a corresponding increase in accounts receivable of $40,000, an increase in inventories of $25,000, and an increase in accounts payable of $35,000.

The following chart shows the expected revenues and operating costs for the new and old machine for each year.

HPCs applicable tax rate is 21%. HPCs weighted-average-cost-of-capital is 14%. HPC uses a 4-year payback period rule, along with NPV, PI, and IRR.

The MACRS 5-year property depreciation schedules are as follows:

Year	Recovery Percentage
1	20%
2	32%
3	19%
4	12%
5	12%
6	5%
