A computer costs $500,000 and is depreciated for tax purposes straight-line over years 1 through 5. Assume that it has zero salvage value at the end of five years. The user wishes to lease the computer by making six annual lease payments, the first of which is due immediately. If taxes are paid without delay and the rate of interest is 10%, what is the minimum acceptable lease payment for a lessor who pays tax at 21%?
