9. FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy, as defined below, gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. For other fair value disclosures, see also Note 5 - Restricted Investments And Bond Collateral and Note 8 - Derivative Instruments.


•	Level 1, defined as observable inputs such as quoted prices in active markets for identical assets.


•	Level 2, defined as observable inputs other than Level 1 prices. These include quoted prices for similar assets or liabilities in an active market, quoted prices for identical assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.


•	Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The table below sets forth, by level, the Company’s financial assets and liabilities that are accounted for at fair value at September 30, 2016:



			Quoted Prices in Active Markets for Identical Assets or Liabilities		Significant Other Observable Inputs
	Fair Value		Level 1		Level 2
	(In thousands)
Assets:
Available-for-sale investments included in Restricted investments	$	77,677	$	77,677	$	—
Available-for-sale investments included in Reclamation deposits	71,734		71,734		—
Total assets	$	149,411	$	149,411	$	—
Liabilities:
Contracts to purchase power included in Other current liabilities and Other liabilities	$	39,164	$	—	$	39,164
Warrants issued by WMLP included in Other liabilities	610		610		—
Total liabilities	$	39,774	$	610	$	39,164

Long-term debt fair value estimates are based on observed prices for securities with an active trading market when available (Level 2) and otherwise using discount rate estimates based on interest rates (Level 3). As of September 30, 2016, the Company valued the WMLP Term Loan Facility and the San Juan Loan with Level 3 fair values. The estimated fair values of the Company’s debt with fixed and variable interest rates are as follows:



	Fixed Interest Rate				Variable Interest Rate
	Carrying Value		Fair Value		Carrying Value		Fair Value
	(In thousands)				(In thousands)
September 30, 2016	$	337,368	$	276,500	$	726,802	$	595,591
December 31, 2015	$	336,000	$	213,500	$	612,727	$	397,601
