Question

Two hazardous environment facilities are being evaluated, with the projected life of

each facility being 10 years. The cash flows for each facility are shown in the table

below.

The company uses a MARR of 14%. Based on the rate of return, which is the most

desirable alternative?

Cash Flows Alternatives

                                               A                                                B

First Cost                      $450,000                                $615,000

M & O Costs                  $15,000                                   $10,000

Annual Benefit              $85,000                                  $158,000

Salvage Value              $45,000                                     $65,000

Explanation / Answer

NPV of A = -450000-15000+85000/1.14 + 85000/1.14^2 + 85000/1.14^3 + 85000/1.14^4 + 85000/1.14^5 + 85000/1.14^6 + 85000/1.14^7 + 85000/1.14^8 + 85000/1.14^9 + 85000/1.14^10 + 45000/1.14^10 =-$9491.70


NPV of B = -615,000-10000+158000/1.14 + 158000/1.14^2 + 158000/1.14^3 + 158000/1.14^4 + 158000/1.14^5 + 158000/1.14^6 + 158000/1.14^7 + 158000/1.14^8 + 158000/1.14^9 + 158000/1.14^10 + 65000/1.14^10 =$216,679.62


B has higher NPV

B is the most

desirable alternative
