Fair Value Measurements [Abstract]
Fair Value Measurements	Note 12. Fair Value Measurements The carrying value of our financial instruments consisting of cash and cash equivalents, deferred compensation, and short term borrowings approximate their fair value. In each instance, fair value is determined after considering Level 1 inputs under the three-level fair value hierarchy. For fair value purposes, the carrying value of cash and cash equivalents approximates fair value due to the short maturity of those investments. The fair value of the assets held by the deferred compensation plan are based on the quoted market prices of the underlying funds which are held in registered investment companies. The carrying value of our revolving credit facilities, classified as short term borrowings, equals fair market value because the interest rate reflects current market rates.
