Jeff & Bezos is a fresh groceries delivery company. The company has access to borrowing funds at a pre-tax rate of 7 % per year. Jeff & Bezos pays income taxes using 23 % tax rate. The company would like to start using high-speed low-altitude drones to deliver grocery purchases directly to residential customers' backyards. The required fleet of drones costs $5,200,000. If the company chooses to buy them, the drones would be losing their economic value following the straight-line depreciation method during a four year period. The fleet of drones, due to their heavy usage, would have no salvage value in four years. Instead of buying the fleet of the drones, Jeff & Bezos is also contemplating leasing them for an estimated pre-tax annual cost of $1,460,000 for four years from a different company. What should Jeff & Bezos do? Should the company buy or lease the drones?
