Fair Value

The majority of the Company’s non-financial assets and liabilities are not required to be carried at fair value on a recurring basis, but the Company is required on a non-recurring basis to use fair value measurements when analyzing asset impairment as it relates to long-lived assets.  The carrying amounts for trade accounts, other receivables, accounts payable and revolving credit borrowings approximate fair value due to either the short-term maturity of these instruments or the fact that the interest rate of the revolving credit borrowings is based upon current market rates. 

Fair value estimates are made at a specific point in time based on relevant market information about the financial instrument.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.
