E21-1 (L02) (Lessee Entries; Capital Lease with Unguaranteed Residual Value) On January 1, 2017, Burke Corporation signed a 5-year noncancelable lease for a machine. The terms of the lease called for Burke to make annual payments of $8,668 at the beginning of each year, starting January 1, 2017. The machine has an estimated useful life of 6 years and a $5,000 unguaranteed residual value. The machine reverts back to the lessor at the end of the lease term.
