QUESTION 1 CASE STUDY ANNUAL WORTH ANALYSIS-THEN AND NOW Background and Information Harry, owner of an automobile battery distributorship in Atlanta, Georgia, performed an economic analysis 3 years ago when he decided to place surge protectors in-line for all his major pieces of testing equipment. The estimates used and the annual worth analysis at MARR = 15% are summarized below. Two different manufacturers' protectors were compared. PowrUp Lloyd's -26,000 -36,000 Cost and installation, $ Annual maintenance cost, $ per year -800 -300 Salvage value, $ 2,000 3,000 Equipment repair savings, $ 25,000 35,000 Useful life, years 6 10 Click Save and Submit to save and submit.

Lloyd's was the clear choice due to its substantially larger AW value. The Lloyd's protectors were installed. 15% MARR PoweUp Lloyd's Investment Annual Repair Investment Annual Repair Years and salvage maintenance savings and salvage maintenance savings 0 -$26,000 $0 $0 $36,000 $0 $0 1 $0 -$800 $25,000 $0 -$300 $35,000 2 $0 -$800 $25,000 $0 -$300 $35,000 3 $0 -$800 $25,000 $0 $300 $35,000 4 $0 -$800 $25,000 $0 -$300 $35,000 5 so -$800 $25,000 $0 -$300 $35,000 6 $0 -$800 $25,000 $0 -$300 $35,000 7 $2,000 -$800 $25,000 $0 -$300 $35,000 8 $0 -$300 $35,000 9 $0 -$300 $35,000 10 $3, -$300 $35,000 AW element -$6,068 -$800 $25,000 -$7,025 -$300 $35,000 Total AW $18,131.35 $27,674.68 During a quick review this last year (year 3 of operation), it was obvious that the maintenance costs and repair savings have not followed and will not follow) the estimates made 3 years ago. In fact, the maintenance contract cost (which includes quarterly inspection) is going from $300 to $1200 per year next year and will then increase 9% per year for the next 10 years. Also, the repair savings for the last 3 years were $25,195, $29,868, and $35,099, as best as Harry can determine. He believes savings will decrease by $2,364 per year hereafter. Finally, these 3-year-old protectors are worth nothing on the market now, so the salvage in 7 years is zero, not $3000. Click Save and Submit to save and submit.
