ALC corp is considering to replace an old machine used in production with a new technically improved one. This old machine has 10 more years of useful life, its current book value is $800,000 and its current market value is $950,000. After 10 years the residual value will be $200,000. The old machine will be sold if company decides to buy the new machine.

The new technically improved machine costs $2 million. It will be used for 10 years and the residual value will be $500,000. The new machine will have lower operating costs.

The company can also lease the new machine for annual lease cost of $200,000 for 10 years. At the end of lease period, the leased machine will have to refurbished before returning to the owner. This refurbish will cost $120,000. The leased machine will produce the same operating costs as new machine.

The annual operating costs information for both machines are as follows

Old machine new machine

For first 5 years $400,000 $100,000

For next 3 years $450,000 $180,000

For last 2 years $480,000 $240,000

Both machines will be overhauled after 5 years (end of year 5). If the company continued with old machine the overhaul cost will be $80,000. Overhaul cost for new machine will be $50,000. There will be no 5^th year overhaul for the leased machine.
