FAIR VALUE MEASUREMENT
FAIR VALUE MEASUREMENT
Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We apply a fair value hierarchy that prioritizes the inputs used to measure fair value:
Level 1: Inputs are valued using quoted market prices in active markets for identical assets or liabilities. Our Level 1 assets primarily include cash and cash equivalents and mutual funds.
Level 2: Inputs are valued based upon quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active. Our Level 2 assets are restricted investments which primarily consist of Municipal Securities, Corporate Securities, U.S. Agency Mortgages and U.S. Agency Debentures. We obtain our inputs from quoted market prices and independent pricing vendors.
Level 3: Inputs are generally unobservable and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability. We currently have no Level 3 assets or liabilities.
The carrying value of our cash and cash equivalents, restricted cash and accounts receivable approximates fair value due to their short term nature. We also hold certain restricted investments which collateralize workers' compensation programs and are classified as held-to-maturity and carried at amortized cost on our Consolidated Balance Sheets. There are inherent limitations when estimating the fair value of financial instruments and the fair values reported are not necessarily indicative of the amounts that would be realized in current market transactions.
The following table presents the fair value and hierarchy for our cash equivalents and restricted investments (in millions):
