What amount of expense should Green recognize in Year Two?

On January 1, Year One, Green Company leases a machine for four years. Because Green is a relatively new business and is struggling with its cash flows, the lessor sets the payments as $10,000 per year for the first two years and $20,000 for the last two years. These payments were computed based on an implicit interest rate of 10 percent per year. The contract does not meet any of the four criteria to be reported as a capital lease.
