Christie Zimmerman is the chief accountant of GG Industries, a large manufacturing company. In addition to its normal business activities, the company has excess warehouse space that it rents out to local businesses. Because the typical renter is a small business, GG Industries requires renters to make lease payments for the entire rental period on the day the lease is signed. As a result, GG Industries typically reports a large unearned rent balance on its balance sheet (a liability). After making adjusting entries for the current year, Christie prepares the adjusted trial balance and notices that the company's earnings have declined significantly. When she presents the adjusted trial balance to the company's CEO, he becomes very concerned about the decline of the earnings. He notices the large unearned rent balance and proposes making an additional end-of-period adjusting entry to record the entire unearned rent balance as earned revenue in the current period. Christie is not in agreement with Mr. Gance's suggestion since the adjusting entry to record the portion of unearned rent that has already been made, and that all account balances are correct in the adjusted trial balance. Mr. Gance insists that Christie make the additional adjustment, saying: "we have already received the cash, we have the right to recognize the revenue in the current period."
