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 marketable securities, which primarily consist of variable-rate demand notes ("VRDNs") and certificate of deposits ("CD"), and restricted investments, which primarily consist of municipal debt-securities, corporate-debt securities, asset-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, marketable securities, 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.

___________
(1)
Cash equivalents and restricted cash equivalents consist of money market funds, deposits, and investments with original maturities of three months or less.
(2)
Marketable securities include CDs and VRDNs, which are classified as available-for-sale. Our CDs include $5.8 million with maturities greater than one year and are classified as Other assets on our Consolidated Balance Sheets. VRDNs with contractual maturities beyond one year are classified as short-term based on their highly liquid nature and because they represent the investment of cash that is available for current operations. Despite the long-term nature of their stated contractual maturities, we routinely buy and sell these securities and believe we have the ability to quickly sell them to the re-marketing agent at par value plus accrued interest in the event we decide to liquidate our investment in a particular VRDN.
(3)
Other restricted investments primarily consist of deferred compensation investments, which are comprised of mutual funds. We have an offsetting accrued liability related to the deferred compensation plan.
(4)
Restricted investments classified as held-to-maturity consist of highly rated investment grade securities, primarily in municipal-debt securities, corporate-debt securities, asset-backed securities, and U.S. agency debentures.
(5)
In connection with our acquisition of MDT effective February 4, 2013, we entered into an unsecured Term Loan Agreement with Synovus Bank. The Term Loan has a variable interest rate and approximates fair value. See Note 9: Commitments and Contingencies for further discussion.
