FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

The Company categorizes its financial instruments measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are:


•	Level 1: Observable inputs obtained from independent sources, such as quoted market prices for identical assets and liabilities in active markets.

•

Level 2: Other inputs, which are observable directly or indirectly, such as quoted market prices for similar assets or liabilities in active markets, quoted market prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair values of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used.


•	Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities.

The following tables present the Company’s financial instruments that are measured at fair value on a recurring basis:

Assets measured at fair value on a nonrecurring basis

The Company’s non-financial assets, such as goodwill, intangible assets and property and equipment are adjusted to fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs.

Financial instruments measured at fair value only for disclosure purposes

The following table presents the carrying value and the fair value of financial instruments measured at fair value only for disclosure purposes:



	March 31, 2018						December 31, 2017
	Carrying value			Fair value			Carrying value			Fair value
	(In thousands)
Current portion of long term debt	$	(13,750	)	$	(13,836	)	$	(13,750	)	$	(13,802	)
Long-term debt, net	(255,027		)	(259,424		)	(258,312		)	(262,230		)
Current portion of long-term debt—related party	—			—			(816		)	(837		)
Long-term debt—related party, net	(2,403		)	(2,652		)	(1,997		)	(2,048		)

The fair value of long-term debt, including the current portion, is estimated using observable market prices or indices for similar liabilities, which are Level 2 inputs. The fair value of long-term debt—related party, including the current portion, is based on Level 3 inputs and is estimated by discounting the future cash flows based on current market conditions.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
