NOTE 4.

Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable and accounts payable and long term debt approximated fair value as of June 30, 2016 and December 31, 2015 due to their short-term nature.

We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less.  As of June 30, 2016 and December 31, 2015, our cash and temporary investments were with high quality financial institutions in Demand Deposit Accounts (DDAs), Short Term Certificates of Deposit and Savings Accounts.

Restricted investments, as of June 30, 2016 of $20.0 million and December 31, 2015 of $21.1 million, included mutual funds which are reported at fair value.  

Our assets and liabilities measured at fair value are based on valuation techniques which consider prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. These valuation methods are based on either quoted market prices (Level 1) or inputs, other than quoted prices in active markets, that are observable either directly or indirectly (Level 2). Cash and cash equivalents, accounts receivable and accounts payable are defined as “Level 1”, while long term debt is defined as “Level 2” of the fair value hierarchy in the Fair Value Measurements and Disclosures Topic of the Codification.
