Fair Value of Financial Instruments

Note 13. 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 considering our credit profile. The carrying value of our variable rate long-term borrowings is a reasonable approximation of fair value due to the variable interest rates. The fair value of our fixed rate and variable rate borrowings is determined using 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:
