20.4 The controller of Tim’s Travel (TT) is deciding between upgrading the
company’s existing computer system or replacing it with a new one. Upgrading the
four-year-old system will cost $97,500 and extend its useful life for another seven years.
The book value is $19,500, although it would sell for $24,000. Upgrading will eliminate
one employee at a salary of $19,400; the new computer will eliminate two employees.
Additional annual operating costs are estimated at $15,950 per year. Upgrading is
expected to increase profits 3.5% above last year’s level of $553,000.
The BetaTech Company has quoted a price of $224,800 for a new computer with a useful life
of seven years. Annual operating costs are estimated to be $14,260. The average processing
speed of the new computer is 12% faster than that of other systems in its price range, which
would increase TT’s profits by 4.5%.
Tim’s present tax rate is 35%, and the cost of financing (minimum desired rate of return) is 11%.
After seven years, the salvage value, net of tax, would be $12,000 for the new computer and
$7,500 for the present system. For tax purposes, computers are depreciated over five full years
(six calendar years; a half year the first and last years), and the depreciation percentages are
as follows:
Year Percent (%)
1 20.00
2 32.00
3 19.20
4 11.52
5 11.52
6 5.76
Using a spreadsheet package, prepare an economic feasibility analysis to determine if Tim’s
Travel should rehabilitate the old system or purchase the new computer. As part of the
analysis, compute the after-tax cash flows for years 1 through 7 and the payback, NPV, and
IRR of each alternative.
As shown below, Tim’s Travel would be better off economically to purchase a new system rather
than updating the existing one. Tim’s Travel can achieve a 13.26% return by purchasing a new
system and an 11.57% return by updating the old system.
Note: For illustrative purposes, all calculations other than NPV and IRR have been rounded to zero
decimal places. All costs and savings amounts are show net of tax effects.
