Fair Value of Financial Instruments
 
Financial instruments recorded at fair value in the consolidated balance sheets, or disclosed at fair value in the footnotes, are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels defined by ASC
820,
Fair Value Measurements and Disclosures
, and directly related to the amount of subjectivity associated with inputs to fair valuation of these assets and liabilities, are as follows:
 
Level
1
Valued based on unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.
 
Level
2
Valued based on either directly or indirectly observable prices for the asset or liability through correlation with market data at the measurement date and for the duration of the instrument’s anticipated life.
 
Level
3
Valued based on management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
 
The following table presents the fair value and hierarchy levels, for financial assets that are measured at fair value on a recurring basis (in thousands):

Derivative financial instruments consist of an interest rate swap for which fair value is determined through the use of a pricing model, that utilizes verifiable inputs such as market interest rates that are observable at commonly quoted intervals for the full term of the swap agreement.
 
The Company has financial instruments, such as accounts receivable, accounts payable, and accrued expenses, that are stated at carrying amounts that approximate fair value because of the short maturity of those instruments. The carrying amount of the Company’s long-term debt approximates fair value as the interest rate on the debt approximates the estimated borrowing rate currently available to the Company
