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 mortgage-backed securities and U.S. agency debentures. Our Level 2 liability is a term loan. 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, other restricted investments 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.
The following table presents the fair value and hierarchy for our cash equivalents, restricted investments and note payable (in millions):

(1)
Cash equivalents and restricted cash equivalents consist of money market funds, deposits and investments with original maturities of three months or less.

Other restricted investments consist of deferred compensation investments which are comprised of mutual funds. We have an offsetting accrued liability related to the deferred compensation plan.

In connection with our acquisition of MDT on February 4, 2013, we entered into an unsecured Term Loan Agreement with Synovus Bank. The Term Loan Agreement is variable rate interest and approximates fair value. See Note 8: Commitments and Contingencies for further discussion.
