	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. See Notes 3, 7 and 8 for additional disclosures related to fair value measurements.

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.


•	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.

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 as of March 31, 2014 (Level 3). The estimated fair values of the Company’s debt with fixed interest rates are as follows:



	Carrying Value		Fair Value
	(In thousands)
December 31, 2013	$	328,473	$	364,329
March 31, 2014	$	777,670	$	823,603

The Company uses derivative financial instruments, primarily foreign exchange contracts, to reduce its exposure to market risks from changes in foreign exchange rates. These foreign exchange contracts are measured at fair value using quoted forward foreign exchange prices from counterparties corroborated by market-based pricing (Level 2). Additional information related to the Company’s derivative financial instruments is disclosed in Note 1 and Note 8 to the consolidated financial statements.

The Company’s non-recurring fair value measurements include asset retirement obligations (refer to Note 7).

The Company determines the estimated fair value of its asset retirement obligations by calculating the present value of estimated cash flows related to reclamation liabilities using Level 3 inputs. The significant inputs used to calculate such liabilities includes estimates of costs to be incurred, the Company’s credit adjusted discount rate, inflation rates and estimated dates of reclamation. The asset retirement liability is accreted to its present value each period and the capitalized asset retirement cost is depleted using the units-of-production method.

The fair value of assets and liabilities acquired through business combinations is calculated using a discounted-cash flow approach using Level 3 inputs. Cash flow estimates require forecasts and assumptions for many years into the future for a variety of factors.


1.	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 Company is required to disclose the fair value of financial instruments where practicable. The carrying amounts of cash equivalents, accounts receivable and accounts payable reflected on the consolidated balance sheets approximate the fair value of these instruments due to the short duration to their maturities. 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 as of December 31, 2013 (Level 3).

The estimated fair value of the Company’s debt with fixed interest rates are as follows:



	Carrying Value		Fair Value
	(In thousands)
December 31, 2012	$	345,408	$	359,753
December 31, 2013	$	328,473	$	364,329

The table below sets forth, by level, the Company’s financial assets and liabilities that are accounted for at fair value on a recurring basis:

- 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.
