Fair Value of Financial Instruments [Abstract]

Fair Value of Financial Instruments

Note 14. Fair Value of Financial Instruments

The fair values of our fixed rate long-term borrowings are calculated by using a discounted cash flow analysis factoring in current market borrowing rates for similar types of borrowing arrangements under our credit profile. The current market borrowing rates are Level 2 inputs under the U.S. GAAP fair value hierarchy. The carrying amounts and fair values of our long-term debt are in the table below:
