The contract calls for four rent payments of $60,000 each, payable semiannually on June 30 and December 31 each year. The equipment was acquired by Jamison Leasing at a cost of $380,000 and was expected to have a useful life of five years with no residual value. Both firms record amortization and depreciation semi-annually. Required: Prepare the appropriate journal entries for the lessor (Jamison Leasing) from the beginning of the lease through the end of 2021. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)
