LONG-TERM DEBT

Fair Value of Debt

Market risk associated with our fixed and variable rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates. In the table below, the aggregate fair value of debt is based primarily on reported market values, recently completed market transactions and estimates based on interest rates, maturities, credit risk and underlying collateral and is classified primarily as Level 2 within the fair value hierarchy.
