NOTE 5.

Fair Value Measurement

The carrying value of cash and cash equivalents, accounts receivable and accounts payable approximated fair value as of March 31, 2018 and December 31, 2017.  At March 31, 2018 and December 31, 2017 the fair value of the Company’s fixed-rate borrowings was $3.5 million and $2.4 million less than the historical carrying value of $244.6 million and $247.1 million.  The fair value of the fixed-rate borrowings was estimated using an income approach based on current interest rates available to the Company for borrowings on similar terms and maturities.

We consider as cash equivalents all highly liquid instruments with an original maturity of three months or less.  As of March 31, 2018 and December 31, 2017, our cash and temporary investments were with high quality financial institutions in Demand Deposit Accounts (DDAs) and Savings Accounts.

Restricted investments, as of March 31, 2018 of $23.3 million and December 31, 2017 of $24.2 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.
