Ross Designs is thinking of replacing its seven-year old knitting machine with a new one that can also emboss designs on cloth. This will allow Ross to sell its textiles, which currently wholesale for $1.2 a yard, for $0.07 a yard more. The embossing should also raise sales 15% to 2.07million yards annually. The new machine costs $320,000, has annual operating costs of $ 27000 and is expected to last for eight years. Labor, materials and other expenses are estimated to rise by $0.02 to $1.10 per yard. Working capital requirements are expected to remain 30% of sales. All working capital investments will be recaptured in eight years. The current machine was purchased for $190,000 and is being deprecited on a straight-line basis assuming a 10 -year life. Its economic life as of today, however, is estimated to be eight years, the same as that of the new machine. It can be sold for $70,000 today or for an estimated salvage value of $5000 in eight years. The new machine will be depreciated straight line over a five-year period and has an estimated salvage value of $20,000 in eight years. The appropriate discount rate is 10%. (20)
