Question

The expected annual maintenance expense for a new piece of equipment is $10,000. This is Alternative A. Alternatively, it is possible to perform the maintenance every fifth year at a cost of $50,000 (Alternative B). In either case, maintenance will be performed in the fifth year so that the equipment can be sold for $100,000 at that time. If the MARR is 15% per year (before income taxes), which alternative should be recommended in each of these situations? Before income taxes are considered. After income taxes are considered when t = 40%. Is there a different selection before and after income taxes are considered?

Explanation / Answer

a)Before taxes considered

PV of cash out flows as per proposal A=$10,000*AFPV for 5 years@15%-$1,00,000*Pv of 5th year

=$10,000*3.3522-$1,00,000*0.4972=-$16,198

PV of cash out flows as per proposal B=$10,000*AFPV for 5 years@15%-$50,000*Pv of 5th year=-$24,860

Proposal B is acceptable

b)

PV of cash out flows as per proposal A=$10,000*AFPV for 5 years@15%*(1-Tax rate)-$1,00,000*Pv of 5th year*(1-Tax rate)

=$10,000*3.3522*.6-$1,00,000*0.4972*.6=-$9,718

PV of cash out flows as per proposal B=$10,000*AFPV for 5 years@15%*.6-$50,000*Pv of 5th year**.6

=-$14,916

Proposal b is acceptble

c) There is no change in decision if tax considered or not in this case
