Answer: NPV = - 4433
As the NPV of the replacement project is negative,
the truck should not be replaced.
Step-by-step explanation:
0 1 2 3
Savings in operating costs (5000-1000): 4000 4000 4000
Incremental depreciation:-
Depreciation on the new truck 10666 14224 4739
Depreciation on the old truck 4000 4000 4000
Incremental depreciation 6666 10224 739
Incremental NOI -2666 -6224 3261
Tax at 40% -1066 -2490 1304
Incremental NOPAT -1599 -3734 1956
Add: Incremental depreciation 6666 10224 739
Incremental OCF 5066 6490 2696
Capital expenditure:-
Cost of new truck 32000
Less: After tax salvage value of old
NOTE THAT, the book value = 4000*3 =
$12,000 (depreciation per annum is 4000
and three years life is left for the old machine)
truck = 7000 + (12000-7000) × 40% = 9000
Net initial investment 23000
Incremental terminal salvage value:-
After tax salvage value of new
truck = 15000 - (15000-2371)× 40% = 9948
Less: After tax salvage value lost on old
truck = 2000 × (1 - 40%) = 1200
Incremental net residual value 8748
After tax annual cash flows -23000 5066 6490 11444
PVIF at 10% 1 0.90909 0.82645 0.75131
PV at 10% -23000 4606 5363 8598
NPV -4433
CONCLUSION:
As the NPV of the replacement project is negative,
the truck should not be replaced.
