Fair Value of Financial Instruments [Abstract]  
Fair Value of Financial Instruments
17) Fair Value of Financial Instruments

We believe the fair value of financial instruments with maturities of less than a year approximate their carrying value due to the short maturity of these instruments or in the case of our variable rate debt, due to the variable interest rates. We elected not to measure any of our financial instruments at fair value and as such will continue to show the fair value of our financial instruments for disclosure purposes only. The fair value of our fixed rate long-term borrowings is calculated using significant other observable inputs (Level 2 inputs under the U.S. GAAP fair value hierarchy). The fair value is calculated using a discounted cash flow analysis factoring in current market borrowing rates for similar types of borrowing arrangements under our credit profile. The carrying amounts and fair values of our long-term debt are in the table below (for disclosure purposes only):
