Question
A defender was installed 10 years ago at a capital investment cost of $77,000. It presently has a market value of $15,000. If kept, the defender has an economic life of three years, operating expenses of
$13,500 per year, and a market value of $9,000 at the end of year (EOY) three. The defender is being depreciated by the straight line method using a 15-year write-off period with an estimated salvage value
for depreciation purposes of $11,000.
As an alternative, the defender can be replaced with a challenger which will cost $65,000 to install, have operating expenses of $9,500 per year, and have a final market value of $9,000 at the end of its
20-year economic life. If the replacement is made, the challenger will be depreciated with the straight line method over a 20-year life with an estimated salvage value of $9,000 at EOY 20. Such equipment
(defender or challenger) will be needed indefinitely. If the after-tax MARR is 9% per year and the effective income tax rate is 25%, should the defender or the challenger be recommended?
