Typically there are two alternatives in a replacementanalysis. One alternative is to replace the defendernow. The other alternative is which one of the fol-lowing?A.Keep the defender for its remaining useful life.B.Keep the defender for another year and thenreexamine the situation.C.Keep the defender until there is an improvedchallenger that is better than the presentchallenger.D.The answer to this question depends on the dataavailable for the defenderand challengeras wellas the assumptionsmade regarding the period ofneeded service and future challengers

The defenders economic life can be found if cer-tain estimates about the defender can be made.Assuming those estimates prove to be exactly cor-rect, one can accurately predict the year whenthe defender should be replaced, even if noth-ing is known about the challenger. True or false?Explain.

A proposal has been made to replace a largeheat exchanger (3 years ago, the initial cost was$85,000) with a new, more efficient unit at acost of $120,000. The existing heat exchangeris being depreciated by the MACRS method. Itspresent book value is $20,400, but its scrap valuejust equals the cost to remove it from the plant.In preparing the before-tax economic analysis,should the $20,400 book value of the old heatexchanger beA.addedto the cost of the new exchanger?B.subtractedfrom the cost of the new exchanger?C.ignoredin this before-tax economic analysis?

Which one of the following is the proper dollarvalue of defender equipment to use in replacementanalysis?A.Original costB.Present market valueC.Present trade-in valueD.Present book valueE.Presentreplacementcost,if different from orig-inal cost

In evaluating projects, LeadTechs engineers usea rate of 15%. One year ago a robotic transfermachine was installed at a cost of $38,000. At thetime, a 10-year life was estimated, but the machinehas had a downtime rate of 28% which is unac-ceptably high. A $12,000 upgrade should fix theproblem, or a labor-intensive process costing $3500in direct labor per year can be substituted. The plantestimates indirect plant expenses at 60% of directlabor, and it allocates front office overhead at 40%of plant expenses (direct and indirect). The robothas a value in other uses of $15,000.

A professor of engineering economics owns a 1996car. In the past 12 months, he has paid $2000 toreplace the transmission, bought two new tires for$160, and installed a CD player for $110. He wantsto keep the car for 2 more years becausehe investedmoney 3 years ago in a 5-year certificate of deposit,which is earmarked to pay for his dream machine, ared European sports car. Today the old cars enginefailed. The professor has two alternatives. He canhave the engine overhauled at a cost of $1800 andthen most likely have to pay another $800 per yearfor the next 2 years for maintenance. The car willhave no salvage value at that time. Alternatively,a colleague offered to make the professor a $5000loan to buy another used car. He must pay the loanback in two equal installments of $2500 due at theend of Year 1 and Year 2, and at the end of the sec-ond year he must give the colleague the car. Thenewused car has an expected annualmaintenancecost of $300. If the professor selects this alterna-tive, he can sell his current vehicle to a junkyard for$1500.Interest is 5%. Using presentworth analysis,which alternative should he select and why?

The Plant Department of the local telephonecompany purchased four special pole hole dig-gers 8 years ago for $14,000 each. They havebeen in constant use to the present. Owing to anincreased workload, additional machines will soonbe required.Recently an improved model of the digger wasannounced. The new machines have a higher pro-duction rate and lower maintenance expense thanthe old machines but will cost $32,000 each witha service life of 8 years and salvage value of $750each. The four original diggers have an immedi-ate salvage of $2000 each and an estimated salvagevalue of $500 each 8 years hence. The averageannual maintenance expense of the old machinesis about $1500 each,compared with $600 each for thenew machines.A field study and trial show that the workloadwould require three additional new machines if theold machines continue in service. However, if theold machines were all retired from service, theworkloadcould be carried by six new machineswithan annual savings of $12,000 in operation costs. Atraining program to prepare employees to run themachines will be necessary at an estimated cost of$700 per new machine. If the MARR is 9% beforetaxes, what should the company do?

MJ Inc. bought a manufacturing line 5 years agofor $35,000,000. At that time it was estimated tohave a service life of 10 years and salvage valueat the end of its service life of $10,000,000. JMJsCFO recently proposed to replace the old line witha modern line expected to last 15 years and cost$95,000,000.This line will provide $5,000,000sav-ings in annual operating and maintenance costs,increase revenues by $2,000,000, and have a$15,000,000 salvage value (after 15 years). Theseller of the new line is willing toacceptthe old lineas a trade-in for its current fair market value, whichis $12,000,000.

A used car can be kept for two more years and thensold for an estimated value of $3000, or it can besold now for $7500. The average annual mainte-nance cost over the past 7 years has been $500 peryear. However, if the car is kept for two more years,this cost is expected to be $1800 the first year and$2000 the second year. As an alternative, a new carcan be purchased for $22,000 and be used for 4years, after which it will be sold for $8,000.

A couple bought their house 10 years ago for$165,000. At the time of purchase, they madea $35,000 down payment, and the balance was financed by a 30-year mortgage with monthly pay-ments of $988.35. They expect to live in this housefor 20 years, after which time they plan to sell thehouse and move to another state. Alternatively, theycan sell the house now and live in a rental unit forthe next 20 years. The house can be sold now for$210,000,from which an8%real estatecommissionand $110,000 remaining loan balance and miscella-neous expenses will be deducted.

The Ajax Corporation purchased a railroad tankcar 8 years ago for $60,000. It is being depreci-ated by SOYD depreciation, assuming a 10-yeardepreciable life and a $7000 salvage value. Thetank car needs to be reconditioned now at a cost of$35,000. If this is done, it is estimated the equip-ment will last for 10 more years and have a $10,000salvage value at the end of the 10 years.On the other hand, the existing tank car couldbe sold now for $10,000 and a new tank carpurchased for $85,000. The new tank car wouldbe depreciated by MACRS depreciation. Its esti-mated actual salvage value after 10 years would be $15,000. In addition, the new tank car would save$7000 per year in maintenance costs, compared tothe reconditioned tank car.Based on a 15% before-tax rate of return,determine whether the existing tank car shouldbe reconditioned or a new one purchased.Note:The problem statement provides more data thanare needed, which is typical of real situations.

Foghorn Leghorn may replace an old egg-sortingmachine used by his business, Foggys Farm FreshEggs. The old egg machine is not quite runningeggs-actly the way it was originally designed andwill require an additional investment now of $2500(expensed at Time 0) to get it back in workingshape. This old machine was purchased 6 yearsago for $5000 and has been depreciated by thestraight-line method at $500 per year. Six years agothe estimated salvage value for tax purposes was$1000. Operating expenses for the old machine areprojected at $600 this next year and are increas-ing by $150 per year each year thereafter. Foggyprojects that with refurbishing, the machine will lastanother 3 years. Foggy believes that he could sellthe old machine as-is today for $1000 to his friendFido to sort bones. He also believes he could sellit 3 years from now at the barnyard flea marketfor $500.The new egg-sorting machine, a deluxe model,has a purchaseprice of $10,000and will last 6 years,at which time it will have a salvage value of $1000.The new machine qualifies as a MACRS 7-yearproperty and will have operating expenses of $100the first year, increasing by $50 per year thereafter.Foghorn uses an after-tax MARR of 18% and a taxrate of 35% on original income.(a)What was the depreciation life used with thedefender asset (the old egg sorter)?(b)Calculate the after-tax cash flows for both thedefender and challenger assets.(c)Use the annual cash flow method to offer arecommendation to Foggy.

A firm is concerned about the condition of someof its plant machinery. Bill James, a newly hiredengineer, reviewed the situation and identified fivefeasible, mutually exclusive alternatives.Alternative A:Spend $44,000 now repairingvarious items. The $44,000 can be charged as acurrent operating expense (rather than capital-ized) and deducted from other taxable incomeimmediately. These repairs will keep the plantfunctioning for 7 years with current operatingcosts. Alternative B:Spend $49,000 to buygeneral-purpose equipment. Depreciationwould be straight line over the equipments7-year useful life. The equipment has no sal- vage value. The new equipment will reduceannual operating costs by $6000.Alternative C:Spend $56,000 to buy newspecialized equipment. This equipment wouldbe depreciated by sum-of-years- digits depre-ciation over its 7-year useful life. Thisequipment would reduce annual operatingcosts by $12,000. It will have no salvagevalue.Alternative D:This alternative is the same asAlternativeB, except it reduces annual operat-ing costs by $7000.Alternative E:This is the do nothingalternative, with annual operating costs $8000above the present level.This profitable firm pays 40% corporate incometaxes and uses a 10% after-tax rate of return. Whichalternative should the firm adopt?

Freds Rodent Control Corporation has been usinga low-frequency sonar device to locate subterraneanpests. This device was purchased 5 years ago for$18,000. The device has been depreciated usingSOYD depreciation with an 8-year depreciable lifeand a salvage value of $3600. Presently, it could besold for $7000. If it is kept for the next 3 years, itsmarket value is expected to drop to $1600.A new lightweight subsurface heat-sensingsearcher(SHSS) that is available for $10,000 wouldimprove the annual net income by $500 for each ofthe next 3 years. The SHSS would be depreciatedas a 5-year class property, using MACRS. At theend of 3 years, the SHSS should have a marketvalue of$4000.Freds RodentControl is a profitableenterprise subject to a 40% tax rate.(a)Construct the after-tax cash flow for the oldsonar unit for the next 3 years.(b)Construct the after-tax cash flow for the SHSSunit for the next 3 years.(c)Construct the after-tax cash flow for thedifference between the SHSS unit and the oldsonar unit for the next 3 years.
