Information about borrowings which initially required repayment in less than twelve months (or normal operating cycle, if longer) after its issuance and that does not otherwise qualify as long-term debt. It typically is comprised of borrowings under letters of credit, lines of credit, commercial paper, and notes payable of short duration. Disclosures include amounts of borrowings under each arrangement, description of underlying arrangements, including repayment terms, interest rates, collateral provided, restrictions on use of assets and activities, whether or not in compliance with debt covenants, and other matters important to users of the financial statements such as the effects of refinancings and noncompliance with debt covenants.
