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 Cost and installation. S -26,000 -36,000 -800 -300 Annual maintenance cost, $ per year 2.000 Salvage value, s 3,000 25,000 35.000 Equipment repair savings. $ 6 10 Useful life. years Save All Answers Close Window Sulmit to me and Smit.

Lloyd's was the clear choice due to its substantially larger AW value. The Lloyd's protectors were installed.

Total AW $27,674.68 During a quick review this last year (years 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 $28,964. S25,201, and $28,216, as best as Harry ean determine. He believes savings will decrease by $3,889 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. Case Study Exercises Q1- Plot a graph of the newly estimated maintenance costs and repair savings projections, assuming the protectors last for seven more years. Q2- With these new estimates, what is the recalculated AW for the Lloyd's protectors? Use the old first cost and maintenance cost estimates for the first 3 years.type your answer in the answer box Q3-If these estimates had been made 3 years ago, would Lloyd's still have been the economic choice Q4-How has the capital recovery amount changed for the Lloyd's protectors with these new estimates? Submission details: 1-Each student must submit an excel file with the required solution (graphs and tables). answers of Q1 & Q2 above. 2- Each Student to submit one file of a hand written verification solution using the factors/tables to calculate the AW value of the revised Lloyds scenario. To be uploaded as image or PDF verification of Q2, answers Q3 &Q4 above
