18.Fair Value of Financial Instruments

We follow a three-level fair value hierarchy that prioritizes the inputs to measure fair value. This hierarchy requires entities to maximize the use of “observable inputs” and minimize the use of “unobservable inputs.” The three levels of inputs used to measure fair value are as follows:
 
Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets as of the measurement date.
 
Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
 
Level 3: Significant unobservable inputs that reflect assumptions that market participants would use in pricing an asset or liability.

The following is a summary of the carrying amounts, estimated fair values, and classifications under the fair value hierarchy of our financial instruments at December 31, 2015 and 2014 (in thousands):

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 underlying assets held by the deferred compensation plan are based on the quoted market prices of the funds 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.
