Your firm has just sold non-strategic assets to raise cash for capital investment while avoiding the use of debt. The firm may buy a piece of machinery for $140,000 [with a useful or depreciable life of 4 years]. Your pretax cost of capital is 8% [and your tax rate is 20%]. You can lease the machine for $43,500 per year and the estimated salvage/recovery value at the end of four years [based on actual market data] is $20,000. Should you lease or buy? Explain by showing your work.
