Builtrite is cоnsidering purchаsing а new mаchine that wоuld cоst $60,000 and the machine would be depreciated (straight line) down to $0 over its five-year life. At the end of four years, it is believed that the machine could be sold for $24,000. The current machine being used was purchased 3 years ago at a cost of $40,000 and it is being depreciated down to zero over its 5-year life. The current machine's salvage value now is $20,000. The new machine would increase EBDT by $46,000 annually and require an additional investment of $5000 in inventory. Builtrite’s marginal tax rate is 34%. What is the TCF associated with the purchase of this machine if it is sold at the end of year 4?
