3. Suppose the units produced and sold over 3 years equal y. Using data from requirement
1, column (1), the relevant cost of upgrade would be $150y + $3,000,000, and from column (2),
the relevant cost of replacing the equipment would be $75y – $450,000 + $4,800,000.
TechGuide would want to upgrade when
4. Operating income for the first year under the upgrade and replace alternatives are shown
below:
Depreciation ($1,080,000a + $3,000,000)
Loss on disposal of old equipment (0; $1,080,000 –
$450,000)
aThe book value of the current production equipment is $1,800,000
3 = $1,080,000; it has a remaining
useful life of 3 years.
First-year operating income is higher by $307,500 ($3,140,000 – $2,832,500) under the upgrade
alternative, and Dan Doria, with his one-year horizon and operating income-based bonus, will
choose the upgrade alternative, even though, as seen in requirement 1, the replace alternative is
better in the long run for TechGuide. This exercise illustrates the possible conflict between the
decision model and the performance evaluation model.
