. Eljer Plumbingware has purchased a new line of industrial robots. The installed first cost of the robots is $200K and they are depreciated via MACRS on a 7 year life. Eljer takes out a loan of $160K which is payable in equal installments over 4 years (each installment paid at the end of the year). The interest rate of the loan is 9%. The robots are estimated to cost $30K the first year in maintenance, and this will increase by $2K each year. The cost savings of the robots is estimated to be $80K the first year and $100K thereafter. The robots will be dismantled and sold after 5 years. Estimated salvage at that time is $20K. Eljer has a tax rate of 21% and an after tax MARR of 12%. . 1 1. Calculate the ATCF (After Tax Cash Flow) for this industrial robot for each year while it is in service. 2.
