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 24 % tax rate. The company would like to start using high-speed low-altitude drones to deliver grocery purchases directly to residential customers' backyards. Doing so would bring the company pre-tax savings in the amount of $3.9 million each year.

The required fleet of drones costs $9 million. If the company chooses to buy them, the drones would be losing their economic value following the straight-line depreciation method during a five year period. The fleet of drones, due to their heavy usage, would have no salvage value at the end.

Instead of buying the fleet of the drones, Jeff & Bezos is also contemplating leasing the drones for a lease term that matches the drones' economic life. It would lease them from a different company, Nets & Flicks, that currently owns the required number of the drones. The estimated annual pre-tax cost of leasing would be $1,940,000. Nets & Flicks requires that the lease payments are made by Jeff & Bezos at the beginning of each year. One additional requirement is that Jeff & Bezos pays a $920,000 security deposit when the lease agreement is being signed, and at the end of the lease term Nets & Flicks promises to give the deposit back to Jeff & Bezos.

When the security deposit is also taken into account, Jeff & Bezos' net advantage to leasing, or NAL, equals _____.
