An asset costs $860,000 and will be depreciated in a straight-line manner over its four-year life. It will have no salvage value. The corporate tax rate is 23 percent and the appropriate interest rate is 9 percent.

b.	Assume that the lessee pays no taxes and the lessor pays taxes. For what range of lease payments does the lease have a positive NPV for both parties?
