Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,300,000; the new one will cost, $1,560,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $300,000 after five years.

The old computer is being depreciated at a rate of $260,000 per year. It will be completely written off in three years. If we don't replace it now, we will have to replace it in two years. We can sell it now for $420,000; in two years, it will probably be worth $120,000. The new machine will save us $290,000 per year in operating costs. The tax rate is 38 percent, and the discount rate is 12 percent.

  1. Suppose we recognize that if we don't replace the computer now, we will be replacing it in two years. Should we replace now or should we wait? Hint: What we effectively have here is a decision either to “invest” in the old computer (by not selling it) or to invest in the new one. Notice that the two investments have unequal lives.
  2. Suppose we consider only whether we should replace the old computer now without worrying about what's going to happen in two years. What are the relevant cash flows? Should we replace it or not? Hint: Consider the net change in the firm's after tax cash flows if we do the replacement.

SOLUTION:-

Equivalent Annual Cost (EAC) method is used to determine the best option under mutually exclusive condition for available altAn old computer is to be replaced with new computer. The old one costs $1,300,000 and new one will cost $1,560,000. The new cCompute the EAC of new Machine as follows: First step: Compute the annual depreciation of new machine. Depreciation - Cost ofSecond step: Calculate the Operating Cash Flow (OCF) from year-1 through year-5 as follows: OCF = Operating cost savings x (1Third step: Compute the after-tax salvage value of the machine at the end of the 5th year as follows: After-tax salvage valueFourth step: Compute the NPV (Net Present Value of new machine as follows: NPV = CF + CF CF__ CF, CF CF; 1+ (1+r)? (1+r) 1+r)Now, compute the EAC of the new machine as follows: NPV EAC = Annuity factor NPV 1-(1+Interest rate) Years Interest rate -$37-curre Compute the EAC of Old Machine in the following steps: First step: Compute the current opportunity cost to retain theSecond step: Compute the after-tax salvage value in two years. After-tax salvage value -salvage value + depreciation -salvageThus, the after-tax salvage value of old machine is $173,200.For old machine the annual operating cash flow will be the depreciation tax shield only Third step: Operating cash flows as fFourth step: Compute the NPV of Old Machine. OCF, OCF, +after-tax salvage value NPV = Opportunity cost +- (1+rate) (1+rate) $Now, compute the EAC of the old machine as follows: EAC = Strate) Years NPV Annuity factor NPV 1-(1+Interest rate) Interest rIn order to determine whether or not replace the old computer now, without worrying about whats going to happen in 2 years cObtained results are provided below: А Input data 2 Discount rate 12% 3 Life of new machine 5 years 4 Life of old machine 3 y
