Fair Value Measurements
The Company estimates the fair value of its financial instruments utilizing a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. There have been no significant transfers into or out of Level 1 or Level 2 inputs during the three and nine months ended September 30, 2011. The following summarizes the three levels of inputs, as well as the assets that the Company values using those levels of inputs.
Level 1: Quoted prices in active markets for identical assets and liabilities. The Company’s Level 1 assets consist of marketable securities (primarily mutual funds) held in the Company’s EDCP and Non-Qualified Plan deferred compensation plans.
Level 2: Observable inputs, other than quoted prices in active markets for identical assets and liabilities, such as quoted prices for similar assets and liabilities; quoted prices in markets that are not active; or other inputs that are observable. The Company’s Level 2 assets consist of money market funds held in the Company’s EDCP and Non-Qualified Plan deferred compensation plans and those recorded in cash and cash equivalents.
Level 3: Unobservable inputs, supported by little or no market data available, where the reporting entity is required to develop its own assumptions to determine the fair value of the instrument. The Company does not currently have any assets whose fair value was determined using Level 3 inputs.

The Company believes that the fair value of its current assets and current liabilities approximate their reported carrying amounts due to the short-term nature of these items. In addition, the interest rates of the Company's Revolver adjust frequently based on current market rates; accordingly its carrying amount approximates fair value.
