Question:
As a result of improvements in product engineering, United Automation is able to sell one of
its two milling machines. Both machines perform the same function but differ in age. The
newer machine could be sold today for $50,000. Its operating costs are $20,000 a year, but in5 years the machine will require a $20,000 overhaul. Thereafter operating costs will be $30,000until the machine is finally sold in year 10 for $5,000.
The older machine could be sold today for $25,000. If it is kept, it will need an immediate
$20,000 overhaul. Thereafter operating costs will be $30,000 a year until the machine is finally
sold in year 5 for $5,000.
Both machines have been fully depreciated for tax purposes before this replacement decision.
The company pays tax at 35 percent. Cash flows have been forecasted in real terms. The realcost of capital is 12 percent.
(Note: the overhaul cost is a capital expenditure and straight line depreciation to zero is used)
Analyse which machine United Automation should sell by answering the following.
(a) Compute the cash flows and NPV of the newer machine if it is kept, without considering
the cash flows associated with the older machine.
(b) Compute the cash flows and NPV of the older machine if it is kept, without considering
the cash flows associated with the newer machine.
(c) Discuss, using the results of parts (a) and (b), which machine should be sold.
(d) Discuss why the payback period cannot be used for the decision regarding which
machine to keep.
