Final answer:
As of December 31, 2010, Irey Co. should report $300,000 as the amount of short-term notes payable on its balance sheet. This figure takes into account the repayment of a portion of the debt prior to the issuance of the balance sheet.
Step-by-step explanation:
The amount of the short-term notes payable that should be reported as current liabilities on the December 31, 2010 balance sheet, which is issued on March 5, 2011 for Irey Co., is $300,000. This accounts for the remaining balance Irey Co. owes after paying off $1,700,000 of its original $2,000,000 debt, with $1,200,000 borrowed from County Bank and $500,000 in additional cash. The amount to be reported on the balance sheet reflects the company's liabilities specifically short-term obligations that are due within one year.
