Suppose that that Orabi Company is considering the purchase of a newer, more efficient yogurt-making machine. If purchased, it would require the new machine on January 2, year 1. Orabi expects to sell 600,000 gallons of milk in each of the next five years at a $2 per gallon selling price.

Orabi has two options:

(1) continue to operate the old machine purchased four years ago or

(2) sell it and purchase the new machine.

The following information has been prepared to help decide which option is more desirable.

	Old Machine	New Machine
Original cost of machine at acquisition	$ 1,600,000	$ 2,000,000
Useful life from date of acquisition	7 years	5 years
Expected annual cash operating expenses:
Variable cost per gallon	$1.20	$1.00
Total fixed cash costs	$ 400,000	$ 160,000

Estimated cash value of machines follows:	Old Machine	New Machine
January 2, Year 1	$ 400,000	$ 2,000,000
December 31, Year 3	$200,000	0
December 31, Year 5	0	$500,000

Orabi is subject to a 40% income tax rate on all income. Assume the company uses the straight-line method for books and tax purposes. Assume that tax depreciation is calculated without regard to salvage value. Use an after-tax discount rate of 10%.
