Detailed Answer
(b) Sale-leaseback transactions are treated as though
two transactions were a single financing transaction, if the lease
qualifies as a capital lease. Any gain on the sale is deferred and
amortized over the lease term (if possession reverts to the lessor)
or the economic life (if ownership transfers to the lessee); both
are ten years in this case. Since this is a capital lease, the entire
gain ($150,000 – $100,000 = $50,000) is deferred at 1/1/Y1. At
12/31/Y1, an adjusting entry must be prepared to amortize 1/10
of the unearned gain (1/10 × $50,000 = $5,000), because the
lease covers ten years. Therefore, the unearned gain at 12/31/Y1
is $45,000 ($50,000 – $5,000).
