a)
To find: Whether the replacement of the computer must take place now or later, and whether the investment hasto be made in the old computer or in the new one.
Introduction:
A decision that concerns the replacement of an asset with a newer version of the same asset is the replacement decision. One of the most significant classifications of capital budgeting is the replacement decision.
a)

Explanation of Solution
Given information:
Person X is planning to replace the old computer with the new one. The cost of the old computer is $1,300,000 and the cost of the new computer is $1,560,000. The
The depreciation for the old computer is made at a rate of $260,000 for a year and will be written off in 3 years. If the replacement does not happen today, then it will be after 2 years. The old computer can be sold now for $420,000 and after 2 years, it will be sold for $120,000. The new computer will save an operating cost of $290,000. The tax rate is 38% and discount rate is 12%.
Explanation:
As the twocomputersdo not have an equal life, the appropriate method to analyze the decision is the equivalent annual cost.
Formula to calculate the operating cash flow using the depreciation tax shield approach:
Computation of the operating cash flow:
Hence, the operating cash flow is $298,360.
Note: The costs are in a positive flow, thus there is a
Formula to calculate the after-tax salvage value:
Computation of the after-tax salvage value:
Hence, the after-tax salvage value is $186,000.
Formula to calculate the
Computation of the net present value:
Formula to calculate the equivalent annual cost:
Computation of the equivalent annual cost:
Hence, the equivalent annual cost is - $105,120.97.
In analyzing the old computer, the only operating cash flow is the depreciation tax shield and it is calculated as follows:
The initial cost of the old computer is not easy to find. It can be assumed that since Person X already owns the old computer, there is no initial payment, but it can be sold and Person X can obtain the
The book value of the old computer is essential to do so. The book value is not stated in the information;however, it is stated that the depreciation of the old computer is $260,000 for a year, and for the next three years. Thus, the book value is assumed to be the overall depreciation amount over the outstanding life of the system or $780,000. The after-tax salvage value of the computer is calculated as follows:
Formula to calculate the after-tax salvage value:
Computation of the after-tax salvage value:
Hence, the after-tax salvage value is $556,800.
This is the old computer’s initial cost at present because Person X forgoes the opportunity to sell it at present. Next, the after-tax salvage value of the computer in the 2 years since it has been purchased has to be calculated. The calculations are as follows:
Hence, the after-tax salvage value is $173,200.
Computation of the net present value of the old computer:
Hence, the net present value is - $251,748.98.
Computation of the equivalent annual cost:
Hence, the equivalent annual cost is - $148,959.40.
Even if Person X plans to replace the two systems in two years, no matter what their decision is today, Person X should replace it at present because the equivalent annual cost is more positive.
b)
To find: The relevant cash flows and whether the system must be replaced or not.
Introduction:
A decision that concerns the replacement of an asset with a newer version of the same asset is the replacement decision. One of the most significant classifications of capital budgeting is the replacement decision.
b)

Explanation of Solution
Given information:
Person X only considers to replace the old computer. The net change in the company’s after tax cash flow is considered if replacement is considered.
Explanation:
If Person X is concerned about whether to replace or not to replace the machine at present, and is not considering the two years, then the net
Time | New computer | Old computer | Difference |
0 | –$1,560,000 | –$556,800 | –$1,003,200 |
1 | 298,360 | 98,800 | 199,560 |
2 | 298,360 | 272,000 | 26,360 |
3 | 298,360 | 0 | 298,360 |
4 | 298,360 | 0 | 298,360 |
5 | 484,360 | 0 | 484,360 |
As Person X is concerned about the marginal cash flows, the cash flow choice to replace the old system with the new system are the differential cash flows.
Computation of the net present value for the replacement decision:
Hence, the net present value is - $127,188.60.
If Person X is not worried with what will happen in 2 years, then the replacement of the old computer should not take place.
