Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The Company's Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles. The preparation of the Company's Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements. Principles of Consolidation The Consolidated Financial Statements include the wholly-owned subsidiaries of the Company, the most significant of which are Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., Wharf Resources (U.S.A.), Empresa Minera Manquiri S.A., and Coeur Capital, Inc. All intercompany balances and transactions have been eliminated. The Company's investments in entities in which it has less than 20% ownership interest are accounted for using the cost method. Revenue Recognition Revenue is recognized, net of treatment and refining charges, when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, no obligations remain, and collection is probable. Under the Company’s concentrate sales contracts with third-party smelters, gold and silver prices are set on a specified future quotational period, typically one to three months, after the shipment date based on market prices. Revenue and Costs Applicable to Sales are recorded on a gross basis under these contracts at the time title passes to the buyer based on the forward price for the expected settlement period. The contracts, in general, provide for provisional payment based upon provisional assays and forward metal prices. Final settlement is based on the average applicable price for the specified future quotational period and generally occurs from three to six months after shipment. The Company’s provisionally priced sales contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates measured at the forward price at the time of sale. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through revenue each period until the date of final gold and silver settlement. Cash and Cash Equivalents Cash and cash equivalents include all highly-liquid investments with an original maturity of three months or less. The Company minimizes its credit risk by investing its cash and cash equivalents with major U.S. and international banks and financial institutions located principally in the United States with a minimum credit rating of A1, as defined by Standard & Poor’s. The Company’s management believes that no concentration of credit risk exists with respect to the investment of its cash and cash equivalents. Receivables Trade receivables and other receivable balances are reported at outstanding principal amounts, net of an allowance for doubtful accounts, if deemed necessary. Management evaluates the collectability of receivable account balances to determine the allowance, if any. Management considers the other party's credit risk and financial condition, as well as current and projected economic and market conditions, in determining the amount of the allowance. Receivable balances are written off when management determines that the balance is uncollectible. Ore on Leach Pads The heap leach process extracts silver and gold by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained silver and gold, which are then recovered in metallurgical processes. The Company uses several integrated steps to scientifically measure the metal content of ore placed on the leach pads. As the ore body is drilled in preparation for the blasting process, samples are taken of the drill residue which are assayed to determine estimated quantities of contained metal. The Company estimates the quantity of ore by utilizing global positioning satellite survey techniques. The Company then processes the ore through crushing facilities where the output is again weighed and sampled for assaying. A metallurgical reconciliation with the data collected from the mining operation is completed with appropriate adjustments made to previous estimates. The crushed ore is then transported to the leach pad for application of the leaching solution. As the leach solution is collected from the leach pads, it is continuously sampled for assaying. The quantity of leach solution is measured by flow meters throughout the leaching and precipitation process. After precipitation, the product is converted to doré at the Rochester mine and a form of gold concentrate at the Wharf mine, representing the final product produced by each mine. The inventory is stated at lower of cost or market, with cost being determined using a weighted average cost method. The historical cost of metal expected to be extracted within twelve months is classified as current and the historical cost of metals contained within the broken ore expected to be extracted beyond twelve months is classified as non-current. Ore on leach pads is valued based on actual production costs incurred to produce and place ore on the leach pad, less costs allocated to minerals recovered through the leach process. The estimate of both the ultimate recovery expected over time and the quantity of metal that may be extracted relative to the time the leach process occurs requires the use of estimates, which are inherently inaccurate due to the nature of the leaching process. The quantities of metal contained in the ore are based upon actual weights and assay analysis. The rate at which the leach process extracts gold and silver from the crushed ore is based upon laboratory testing and actual experience of more than twenty years of leach pad operations at the Rochester mine and thirty years of leach pad operations at the Wharf mine. The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis. Metal and Other Inventory Inventories include concentrate, doré, and operating materials and supplies. The classification of inventory is determined by the stage at which the ore is in the production process. All inventories are stated at the lower of cost or market, with cost being determined using a weighted average cost method. Concentrate and doré inventory includes product at the mine site and product held by refineries. Metal inventory costs include direct labor, materials, depreciation, depletion and amortization as well as overhead costs relating to mining activities. Property, Plant, and Equipment Expenditures for new facilities, assets acquired pursuant to capital leases, new assets or expenditures that extend the useful lives of existing facilities are capitalized and depreciated using the straight-line method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such facilities, lease term, or the useful life of the individual assets. Productive lives range from 7 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Certain mining equipment is depreciated using the units-of-production method based upon estimated total proven and probable reserves. Mining Properties and Mine Development Capitalization of mine development costs begins once all operating permits have been secured, mineralization is classified as proven and probable reserves and a final feasibility study has been completed. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Costs incurred before mineralization are classified as proven and probable reserves are expensed and classified as exploration or pre-development expense. Mine development costs are amortized using the units of production method over the estimated life of the ore body based on recoverable ounces to be mined from proven and probable reserves. Interest expense allocable to the cost of developing mining properties and to construct new facilities is capitalized until assets are ready for their intended use. Drilling and related costs incurred at the Company’s operating mines are expensed as incurred in Exploration, unless the Company can conclude with a high degree of confidence, prior to the commencement of a drilling program, that the drilling costs will result in the conversion of a mineral resource into proven and probable reserves. The Company’s assessment is based on the following factors: results from previous drill programs; results from geological models; results from a mine scoping study confirming economic viability of the resource; and preliminary estimates of mine inventory, ore grade, cash flow and mine life. In addition, the Company must have all permitting and/or contractual requirements necessary to have the right to and/or control of the future benefit from the targeted ore body. The costs of a drilling program that meet these criteria are capitalized as mine development costs. Drilling and related costs of approximately $6.0 million and $8.9 million at December 31, 2015 and 2014, respectively, were capitalized. The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Costs applicable to sales in the same period as the revenue from the sale of inventory. Mineral Interests Significant payments related to the acquisition of land and mineral rights are capitalized. Prior to acquiring such land or mineral rights, the Company generally makes a preliminary evaluation to determine that the property has significant potential to develop an economic ore body. The time between initial acquisition and full evaluation of a property’s potential is variable and is determined by many factors including: location relative to existing infrastructure, the property’s stage of development, geological controls and metal prices. If a mineable ore body is discovered, such costs are amortized when production begins using the units-of-production method based on recoverable ounces to be mined from proven and probable reserves. If no mineable ore body is discovered, such costs are expensed in the period in which it is determined the property has no future economic value. Write-downs We review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated undiscounted pre-tax future cash flows are less than the carrying amount of the asset. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of future cash flows from other asset groups. An impairment loss is measured by discounted estimated future cash flows, and recorded by reducing the asset's carrying amount to fair value. Future cash flows are estimated based on estimated quantities of recoverable minerals, expected silver and gold prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. The significant assumptions used in determining future cash flows for each mine site asset group at December 31, 2015, apart from production cost and capitalized expenditure assumptions unique to each operation, included long-term silver and gold prices of $17.50 and $1,200 per ounce (consistent with the Company’s long-term reserve prices), respectively, and discount rates ranging from 7.50% - 11.00% (to reflect project and country-specific risks). During 2015, 2014, and 2013, we recorded impairments of $313.3 million , $1,472.7 million , and $773.0 million , respectively, to reduce the carrying value of mining properties and property, plant and equipment as part of Write-downs. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization other than proven and probable reserves are included when determining the fair value of mine site asset groups at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of silver and gold that will be obtained after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from exploration stage mineral interests are risk adjusted based on management’s relative confidence in such materials. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those risk factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material could ultimately be mined economically. Assets classified as exploration potential have the highest level of risk that the carrying value of the asset can be ultimately realized, due to the still lower level of geological confidence and economic modeling. Silver and gold prices are volatile and affected by many factors beyond the Company’s control, including prevailing interest rates and returns on other asset classes, expectations regarding inflation, speculation, currency values, governmental decisions regarding precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors may affect the key assumptions used in the Company’s impairment testing. Various factors could impact our ability to achieve forecasted production levels from proven and probable reserves. Additionally, production, capital and reclamation costs could differ from the assumptions used in the cash flow models used to assess impairment. Actual results may vary from the Company’s estimates and result in additional Write-downs . Restricted Assets The Company, under the terms of its self-insurance and bonding agreements with certain banks, lending institutions and regulatory agencies, is required to collateralize certain portions of its obligations. The Company has collateralized these obligations by assigning certificates of deposit that have maturity dates ranging from three months to a year, to the respective institutions or agencies. At December 31, 2015 and 2014, the Company held certificates of deposit and cash under these agreements of $6.3 million and $7.0 million , respectively. The ultimate timing of the release of the collateralized amounts is dependent on the timing and closure of each mine and repayment of the facility. In order to release the collateral, the Company must seek approval from certain government agencies responsible for monitoring the mine closure status. Collateral could also be released to the extent the Company is able to secure alternative financial assurance satisfactory to the regulatory agencies. The Company believes there is a reasonable probability that the collateral will remain in place beyond a twelve-month period and has therefore classified these investments as long-term. Reclamation The Company recognizes obligations for the expected future retirement of tangible long-lived assets and other associated asset retirement costs. The fair value of a liability for an asset retirement obligation will be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period in Pre-development, reclamation, and other . As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced. Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the discounted costs expected to be incurred at the site. Such cost estimates include, where applicable, ongoing care and maintenance and monitoring costs. Changes in estimates are reflected prospectively in the period an estimate is revised. Foreign Currency The assets and liabilities of the Company’s foreign subsidiaries are measured using U.S. dollars as their functional currency. Revenues and expenses are translated at the average exchange rate for the period. Foreign currency gains and losses are included in the determination of net income or loss. Derivative Financial Instruments The Company recognizes all derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in the value of derivative instruments are recorded each period in the Consolidated Statement of Comprehensive Income (Loss) in Fair value adjustments, net . Management applies judgment in estimating the fair value of instruments that are highly sensitive to assumptions regarding commodity prices, market volatilities, and foreign currency exchange rates. Stock-based Compensation Plans The Company estimates the fair value of stock options using the Black-Scholes option pricing model and stock appreciation rights (“SARs”) awards using market comparison. Stock options granted are accounted for as equity-based awards and SARs are accounted for as liability-based awards. The value of the SARs is remeasured at each reporting date. The Company estimates the fair value of performance share and performance unit grants using a Monte Carlo simulation valuation model. Performance shares granted are accounted for as equity based awards and performance shares units are accounted for as liability-based awards. The Company estimates forfeitures of stock-based awards based on historical data and periodically adjusts the forfeiture rate. The adjustment of the forfeiture rate is recorded as a cumulative adjustment in the period the forfeiture estimate is changed. Compensation costs related to stock based compensation are included in General and administrative expenses , Costs applicable to sales , and Property, plant, and equipment, net as deemed appropriate. Restricted stock and restricted stock units granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant. Restricted stock awards are accounted for as equity-based awards and restricted stock unit awards are accounted for as liability-based awards. Restricted stock units are remeasured at each reporting date. Restricted stock units are settled in cash based on the number of vested restricted stock units multiplied by the current market price of the common shares when vested. Holders of the restricted stock are entitled to vote the shares and to receive any dividends declared on the shares. Income and Mining Taxes The Company uses an asset and liability approach which results in the recognition of deferred tax liabilities and assets for the expected future tax consequences or benefits of temporary differences between the financial reporting basis and the tax basis of assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. A valuation allowance has been provided for the portion of the Company’s net deferred tax assets for which it is more likely than not that they will not be realized. Revisions During 2015, the Company completed a reconciliation of its tax basis assets and liabilities, as well as a comprehensive analysis of its income and mining taxes receivable and payable, which identified prior year immaterial errors of $31.0 million . The Company's results have been revised to reflect the adjustment in Income and mining tax (expense) benefit, Deferred tax liabilities, and Receivables for the year ended December 31, 2014. Certain immaterial amounts in prior years relating to foreign exchange impacts on cash have been reclassified to conform to the current presentation of the Consolidated Statement of Cash Flows. Recent Accounting Standards In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes," which requires entities with a classified balance sheet to present all deferred tax assets and liabilities as non-current. The updated guidance became effective under early adoption for the Company's fiscal year beginning January 1, 2015, and resulted in a reclassification of amounts from Current deferred tax assets to Non-current deferred tax assets and Current deferred tax liabilities to Non-current deferred tax liabilities in the current and prior periods. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. These changes become effective for the Company's fiscal year beginning January 1, 2016. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows. In August 2015, the FASB issued ASU 2015-14, "Deferral of the Effective Date" , which defers the effective date of ASU 2014-09, "Revenue from Contracts with Customers" to January 1, 2018. The Company is currently evaluating the potential impact of adopting the prescribed changes on the Company's consolidated financial position, results of operations, and cash flows. In July 2015, the FASB issued ASU 2015-11, " Simplifying the Measurement of Inventory," which provides a revised, simpler measurement for inventory to be measured at the lower of cost and net realizable value. These changes become effective for the Company's fiscal year beginning January 1, 2018. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows. In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," which requires that debt issuance costs related to a recognized debt liability be presented as a reduction to the carrying amount of that debt liability, not as an asset. The updated guidance became effective under early adoption for the Company's fiscal year beginning January 1, 2015, and resulted in a reclassification of amounts from Other Non-current Assets to Debt in the current and prior periods. In February 2015, the FASB issued ASU 2015-02, "Amendments to the Consolidation Analysis," which amends the consolidation requirements in ASC 810. These changes become effective for the Company's fiscal year beginning January 1, 2016. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows.

benchmark standards set by the London Bullion Market Association, which regulates the acceptable requirements for bullion traded in the London precious metals markets. The Company then sells its silver and gold bullion to multi-national banks, bullion trading houses, and refiners across the globe. The Company has eleven trading counterparties and the sales of metals to these companies amounted to approximately 74% , 63% , and 72% of total metal sales for the years ended December 31, 2015, 2014, and 2013, respectively. Generally, the loss of a single bullion trading counterparty would not adversely affect the Company due to the liquidity of the markets and the availability of alternative trading counterparties. The Company's concentrate produced by the Kensington mine is sold to smelters under purchase and sale agreements, and the smelters pay the Company for the gold or silver recovered from the concentrates. The Company currently sells concentrate to three smelters, and sales to these companies amounted to approximately 26% , 37% , and 28% of total metal sales for the years ended December 31, 2015, 2014, and 2013, respectively. While the loss of any one smelter may have a material adverse effect if alternate smelters are not available, the Company believes that there is sufficient global capacity available to address the loss of a smelter. The following table indicates customers that represent 10% or more of total sales of metal for at least one of the years December 31, 2015, 2014, and 2013 (in millions): Years Ended December 31, Customer 2015 2014 2013 Segments reporting revenue Mitsui & Co. $ 137.7 $ 133.8 $ 70.3 Palmarejo, Rochester China National Gold 126.2 86.8 81.5 Kensington Asahi (formerly Johnson Matthey) 84.2 71.8 66.4 Wharf, Rochester, San Bartolomé TD Securities 81.3 106.7 106.7 Palmarejo, Rochester Standard Bank 34.7 87.5 69.0 Palmarejo, Rochester INTL Commodities 33.1 22.4 84.6 Palmarejo, San Bartolomé, Rochester Valcambi — 33.9 77.2 Palmarejo, San Bartolomé Auramet — 10.8 111.7 Palmarejo, San Bartolomé, Kensington, Rochester

The non-cash impairment charges were largely driven by significant decreases in long-term metal price assumptions and revised mine plans in the fourth quarter. For purposes of this evaluation, estimates of future cash flows of the individual reporting units were used to determine fair value. The estimated cash flows were derived from life-of-mine plans, developed using long-term pricing reflective of the current price environment and management’s projections for operating costs. The 2014 write-down of $1,472.7 million ( $1,021.8 million net of tax) was primarily due to a $784.0 million impairment of the Palmarejo complex ( $504.5 million net of tax) and a $372.5 million impairment of the La Preciosa project ( $244.9 million net of tax) due to a decrease in the Company's long-term silver and gold price assumptions reflective of the current silver and gold price environment and revised mine plans. The 2013 write-down of $773.0 million was primarily due to a $642.1 million impairment of the Palmarejo complex ( $462.3 million net of tax) and a $130.7 million impairment of the Kensington mine due to a decrease in the Company's long-term silver and gold price assumptions reflective of the current silver and gold price environment.

Asset Retirement Obligation Disclosure [Abstract]
RECLAMATION	RECLAMATION Reclamation and mine closure costs are based principally on legal and regulatory requirements. Management estimates costs associated with reclamation of mining properties. The Company uses assumptions about future costs, mineral prices, mineral processing recovery rates, production levels, capital costs, and reclamation costs. On an ongoing basis, management evaluates its estimates and assumptions, and future expenditures could differ from current estimates. Changes to the Company’s asset retirement obligations for operating sites are as follows: Year ended December 31, In thousands 2015 2014 Asset retirement obligation - Beginning $ 67,214 $ 55,966 Accretion 7,738 4,826 Additions and changes in estimates 11,939 6,748 Settlements (4,819 ) (326 ) Asset retirement obligation - Ending $ 82,072 $ 67,214 The increase in asset retirement obligations in the year ended December 31, 2015 is primarily due to the acquisition of the Wharf gold mine. The Company has accrued $3.2 million and $3.6 million at December 31, 2015 and December 31, 2014 , respectively, for reclamation liabilities related to former mining activities, which are included in Reclamation.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company has stock incentive plans for executives and eligible employees. Stock awards include stock options, restricted stock, and performance shares. The Company previously awarded stock appreciation rights, restricted stock units, and performance share units. Stock-based compensation expense for the years ended December 31, 2015, 2014, and 2013 was $9.3 million , $9.3 million , and $4.8 million , respectively. At December 31, 2015, there was $8.0 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.4 years. Stock Options and Stock Appreciation Rights Stock options and stock appreciation rights (SARs) granted under the Company’s incentive plans vest over three years and are exercisable over a period not to exceed ten years from the grant date. The exercise price of stock options is equal to the fair market value of the shares on the date of the grant. The value of each stock option award is estimated using the Black-Scholes option pricing model. Stock options are accounted for as equity awards and SARs are accounted for as liability awards and remeasured at each reporting date. SARs, when vested, provide the participant the right to receive cash equal to the excess of the market price of the shares over the exercise price when exercised. The following table sets forth the weighted average fair value of stock options and the assumptions used to estimate the fair value of the stock options using the Black-Scholes option valuation model: 2015 2014 2013 Weighted average fair value of stock options granted $ 2.65 $ 3.79 $ 12.60 Volatility 55.71 % 50.93 % 76.74 % Expected life in years 4.75 3.9 5.0 Risk-free interest rate 1.51 % 1.25 % 0.84 % Dividend yield — — — The following table summarizes stock option and SAR activity for the years ended December 31, 2015, 2014, and 2013: Stock Options SARs Shares Weighted Average Exercise Price Shares Weighted Outstanding at December 31, 2012 370,000 $ 30.20 68,865 $ 13.83 Granted 190,452 20.41 — — Exercised (13,027 ) 10.77 (6,617 ) 13.14 Canceled/forfeited (131,855 ) 29.30 (12,039 ) 15.40 Outstanding at December 31, 2013 415,570 27.36 50,209 14.15 Granted 415,172 9.45 — — Exercised — — — — Canceled/forfeited (232,396 ) 23.94 (3,637 ) 15.40 Outstanding at December 31, 2014 598,346 16.26 46,572 14.06 Granted 310,028 5.57 — — Exercised — — — — Canceled/forfeited (238,365 ) 12.69 — — Outstanding at December 31, 2015 670,009 $ 12.58 46,572 $ 14.06 Options Outstanding Options Exercisable Range of Exercise Price Number Outstanding Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) Number Exercisable Weighted Average Exercise Price Weighted Average Remaining Contractual Life (Years) $ 0.00-$10.00 439,746 $ 7.33 8.71 75,613 $ 9.41 7.49 $10.00-$20.00 71,540 13.42 7.56 40,823 14.56 7.31 $20.00-$30.00 149,992 25.63 6.31 126,828 25.98 6.17 $30.00-$40.00 3,134 39.90 1.22 3,134 39.90 1.22 $40.00-$50.00 3,336 48.50 2.03 3,336 48.50 2.03 $50.00-$60.00 2,261 51.40 0.14 2,261 51.40 0.14 670,009 $ 12.58 251,995 $ 19.86 At December 31, 2015, there was $0.4 million of unrecognized compensation cost related to non-vested stock options to be recognized over a weighted average period of 1.1 years. Restricted Stock and Restricted Stock Units Restricted stock granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant and vest in equal installments annually over three years. Restricted stock awards are accounted for as equity awards and restricted stock unit awards were accounted for as liability awards. Restricted stock units were remeasured at each reporting date and settled in cash based on the number of vested restricted stock units multiplied by the current market price of the common shares when vested. Holders of restricted stock are entitled to vote the shares and to receive any dividends declared on the shares.

Performance Shares and Performance Share Units Performance shares granted under the Company’s incentive plans are accounted for at fair value using a Monte Carlo simulation valuation model on the date of grant. Performance share awards are accounted for as equity awards and performance units are accounted for as liability-based awards and remeasured each reporting date. The performance shares vest at the end of a three-year service period if relative stockholder return and internal performance metrics are met. The existence of a market condition requires recognition of compensation cost for the performance share awards over the requisite period regardless of whether the relative stockholder return metric is met. Performance share units were settled in cash based on the current market price of the common shares when vested. The following table summarizes performance shares and performance units’ activity for the years ended December 31, 2015, 2014, and 2013: Performance Shares Performance Units Number of Shares Weighted Average Grant Date Fair Value Number of Units Weighted Average Fair Value Outstanding at December 31, 2012 109,159 $ 26.92 34,239 $ 39.78 Granted 173,773 23.35 34,239 38.02 Vested (4,160 ) 30.97 (68,478 ) 38.02 Cancelled/Forfeited (68,377 ) 34.49 — — Outstanding at December 31, 2013 210,395 28.04 — — Granted 358,398 12.21 — — Vested (34,611 ) 27.18 — — Cancelled/Forfeited (17,352 ) 27.15 — — Outstanding at December 31, 2014 516,830 17.61 — — Granted 809,293 6.97 — — Vested — — — — Cancelled/Forfeited (190,988 ) 15.62 — — Outstanding at December 31, 2015 1,135,135 $ 10.35 — $ — At December 31, 2015, there was $3.7 million of unrecognized compensation cost related to performance shares to be recognized over a weighted average period of 1.7 years. Supplemental Incentive Plan In 2014, the Company adopted a supplemental incentive plan under which benefits are payable upon achievement of certain performance and market conditions. The maximum potential incentive payout under the plan is $3.8 million , of which $2.8 million may be settled in cash or stock at the Company’s discretion. At December 31, 2015, $2.2 million has been accrued for this plan.

Based upon this analysis, the Company has recorded valuation allowances as follows: Year ended December 31, In thousands 2015 2014 U.S. $ 292,677 $ 305,534 Argentina 8,376 21,520 Canada 1,718 2,009 Bolivia 45,177 15,948 Mexico 63,373 14,816 New Zealand 25,508 28,710 Other — 2,973 $ 436,829 $ 391,510 The Company has the following tax attribute carryforwards at December 31, 2015, by jurisdiction: In thousands U.S. Argentina Bolivia Canada Mexico New Zealand Other Total Regular net operating losses 320,511 12,210 55,019 2,182 108,191 91,096 68 589,277 Alternative minimum tax net operating losses 187,376 — — — — — — 187,376 Capital losses 11,195 — — — — — — 11,195 Alternative minimum tax credits 3,173 — — — — — — 3,173 Foreign tax credits 19,898 — — — — — — 19,898 The U.S. net operating losses expire from 2019 through 2035 and the Canada net operating losses will expire from 2029 through 2035. The Mexico net operating losses expire from 2017 to 2035, while the remaining net operating losses from the foreign jurisdictions have an indefinite carryforward period. The majority of the U.S. capital losses expired in 2015. Alternative minimum tax credits do not expire and foreign tax credits expire if unused beginning in 2019. The Company intends to indefinitely reinvest earnings from certain foreign operations. For the years 2015 and 2014, the Company had no unremitted earnings from these specific foreign operations. A reconciliation of the beginning and ending amount related to unrecognized tax benefits is below (in thousands): Unrecognized tax benefits at January 1, 2014 $ 15,471 Gross increase to current period tax positions 1,856 Gross increase to prior period tax positions 524 Reductions in unrecognized tax benefits resulting from a lapse of the applicable statute of limitations (1,767 ) Unrecognized tax benefits at December 31, 2014 $ 16,084 Gross increase to current period tax positions 1,030 Gross increase to prior period tax positions 810 Reductions in unrecognized tax benefits resulting from a lapse of the applicable statute of limitations — Unrecognized tax benefits at December 31, 2015 $ 17,924 At December 31, 2015, 2014, and 2013, $17.9 million , $16.1 million , and $14.3 million , respectively, of these gross unrecognized benefits would, if recognized, decrease the Company's effective tax rate. The Company operates in numerous countries around the world and is subject to, and pays annual income taxes under, the various income tax regimes in the countries in which it operates. The Company has historically filed, and continues to file, all required income tax returns and paid the taxes reasonably determined to be due. The tax rules and regulations in many countries are highly complex and subject to interpretation. From time to time, the Company is subject to a review of its historic income tax filings and, in connection with such reviews, disputes can arise with the taxing authorities over the interpretation or application of certain rules to the Company’s business conducted within the country involved. The Company files income tax returns in various U.S. federal and state jurisdictions, in all identified foreign jurisdictions, and various others. The statute of limitations remains open from 2012 for the US federal jurisdiction and from 2008 for certain other foreign jurisdictions. During 2014, the U.S. Internal Revenue Service concluded its examination of the Company's 2009, 2010, and 2011 tax years. As a result of statutes of limitations that will begin to expire within the next 12 months in various jurisdictions and possible settlement of audit-related issues with taxing authorities in various jurisdictions with respect to which none of these issues are individually significant, the Company believes that it is reasonably possible that the total amount of its unrecognized income tax liability will decrease between $0.5 million and $1.0 million in the next 12 months. The Company classifies interest and penalties associated with uncertain tax positions as a component of income tax expense and recognized interest and penalties of $9.2 million , $6.9 million , and $4.1 million at December 31, 2015, 2014, and 2013, respectively.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the years ended December 31, 2015 , 2014 , and 2013, 3,239,425 , 1,871,681 , and 1,111,021 , respectively, of common stock equivalents related to equity-based awards were not included in the diluted per share calculation as the shares would be antidilutive. The 3.25% Convertible Senior Notes were not included in the computation of diluted net income (loss) per share for the years ended December 31, 2015 , 2014 , and 2013 because there is no excess value upon conversion over the principal amount of the Notes.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), secondary priority to quoted prices in inactive markets or observable inputs (Level 2), and the lowest priority to unobservable inputs (Level 3). The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: Fair Value at December 31, 2015 In thousands Total Level 1 Level 2 Level 3 Assets: Equity securities $ 2,766 $ 2,756 $ — $ 10 Liabilities: Palmarejo royalty obligation embedded derivative $ 4,957 $ — $ — $ 4,957 Rochester NSR royalty obligation 9,593 — — 9,593 Other derivative instruments, net 508 — 508 — $ 15,058 $ — $ 508 $ 14,550 Fair Value at December 31, 2014 In thousands Total Level 1 Level 2 Level 3 Assets: Equity securities $ 5,982 $ 4,603 $ — $ 1,379 Silver and gold options 3,882 — 3,882 — $ 9,864 $ 4,603 $ 3,882 $ 1,379 Liabilities: Palmarejo royalty obligation embedded derivative $ 21,912 $ — $ — $ 21,912 Rochester NSR royalty obligation 15,370 — — 15,370 Silver and gold options 1,039 — 1,039 — Other derivative instruments, net 805 — 805 — $ 39,126 $ — $ 1,844 $ 37,282 The Company’s investments in equity securities are recorded at fair market value in the financial statements based primarily on quoted market prices. Such instruments are classified within Level 1 of the fair value hierarchy. Quoted market prices are not available for certain equity securities; these securities are valued using pricing models, which require the use of observable and unobservable inputs, and are classified within Level 3 of the fair value hierarchy. The Company’s silver and gold options and other derivative instruments, net, which relate to concentrate and certain doré sales contracts and foreign exchange contracts, are valued using pricing models, which require inputs that are derived from observable market data, including contractual terms, forward market prices, yield curves, credit spreads, and other unobservable inputs. The model inputs can generally be verified and do not involve significant management judgment. Such instruments are classified within Level 2 of the fair value hierarchy. The fair values of the Palmarejo royalty obligation embedded derivative and Rochester NSR royalty obligation were estimated based on observable market data including contractual terms, forward silver and gold prices, yield curves, and credit spreads, as well as the Company’s current mine plan which is considered a significant unobservable input. Therefore, the Company has classified these obligations as Level 3 financial liabilities. Based on current mine plans, expected royalty durations of 0.7 years and 2.5 years were used to estimate the fair value of the Palmarejo royalty obligation embedded derivative and Rochester NSR royalty obligation, respectively, at December 31, 2015 . No assets or liabilities were transferred between fair value levels in the year ended December 31, 2015 .

DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Palmarejo Gold Production Royalty On January 21, 2009, the Company's subsidiary, Coeur Mexicana S.A. de C.V. ("Coeur Mexicana"), entered into a gold production royalty agreement with a subsidiary of Franco-Nevada Corporation. The royalty covers 50% of the life of mine production from the Palmarejo mine and legacy adjacent properties, excluding production from the recently acquired Paramount Gold and Silver Corp. ("Paramount") properties. The royalty transaction includes a minimum obligation of 4,167 gold ounces per month and terminates when payments on 400,000 gold ounces have been made. At December 31, 2015 , a total of 33,495 gold ounces remain outstanding under the obligation. The price volatility associated with the minimum royalty obligation is considered an embedded derivative. The Company is required to recognize the change in fair value of the remaining minimum obligation due to changing gold prices. Unrealized gains are recognized in periods when the gold price has decreased from the previous period and unrealized losses are recognized in periods when the gold price increases. The fair value of the embedded derivative is reflected net of the Company's current credit adjusted risk free rate, which was 19.9% and 11.8% at December 31, 2015 and December 31, 2014 , respectively. The fair value of the embedded derivative at December 31, 2015 and December 31, 2014 was a liability of $5.0 million and $21.9 million , respectively. The mark-to-market adjustments were gains of $17.0 million , $18.4 million , and $104.8 million for the years ended December 31, 2015 , 2014 , and 2013, respectively. Payments on the royalty obligation decrease the carrying amount of the minimum obligation and the derivative liability. Each monthly payment is an amount equal to the greater of the minimum of 4,167 ounces of gold or 50% of actual gold production multiplied by the excess of the monthly average market price of gold above $412 per ounce, subject to a 1% annual inflation adjustment. Realized losses on settlement of the liabilities were $13.9 million , $20.4 million , and $28.6 million for the years ended December 31, 2015 , 2014 , and 2013, respectively. The mark-to-market adjustments and realized losses are included in Fair value adjustments, net . Provisional Silver and Gold Sales The Company enters into sales contracts with third-party smelters and refiners which, in most cases, provide for a provisional payment based upon preliminary assays and quoted metal prices. The provisionally priced sales contracts contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable recorded at the forward price at the time of sale. The embedded derivatives do not qualify for hedge accounting and are marked to market through earnings each period until final settlement. Changes in silver and gold prices resulted in provisional pricing mark-to-market gains of $0.3 million , losses of $0.1 million , and losses of $2.0 million in the years ended December 31, 2015 , 2014 , and 2013, respectively.

In addition, to allow for situations where derivative positions may need to be revised, the Company transacts only in markets that management considers highly liquid.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS On April 17, 2015 , the Company completed the acquisition of Paramount, which held mineral claims adjacent to the Company's Palmarejo mine, including a continuation of the Independencia deposit. Upon closing, Paramount became a wholly-owned subsidiary of the Company, and each issued and outstanding share of Paramount common stock was converted into 0.2016 shares of Coeur common stock, with cash paid in lieu of fractional shares. Immediately prior to completion of the acquisition, Paramount spun off to its existing stockholders a separate, publicly-traded company, Paramount Gold Nevada Corp. ("SpinCo"), which owns the Sleeper Gold Project and other assets in Nevada. SpinCo was capitalized with $8.5 million in cash contributed by Coeur, which amount has been included in the total consideration paid for the acquisition of Paramount. The Company also paid $1.5 million to acquire 4.9% of the newly issued and outstanding shares of SpinCo. The transaction was accounted for as an asset acquisition, as Paramount is an exploration stage project, which requires that the total purchase price be allocated to the assets acquired and liabilities assumed based on their relative fair values.

The Term Loan contains no financial maintenance covenants and currently bears interest at a rate equal to an adjusted Eurodollar rate plus a margin of 8.00% (at no time will the adjusted Eurodollar rate be deemed to be less than 1.00% per annum). Voluntary prepayments of the Term Loan under the Term Loan Credit Agreement are permitted, subject to the payment of a make-whole premium if such prepayment occurs prior to the first anniversary of the closing date, a premium of 105.0% of the principal amount between the first anniversary and the second anniversary of the closing date and a premium of 103.0% if such prepayment occurs on or after the second anniversary but prior to the third anniversary of the closing date. The Term Loan Credit Agreement requires amortization payments equal to 1.0% of the principal amount of the Term Loan per annum and also requires net cash proceeds of debt issuances, excess cash flow, asset sales and casualty insurance recoveries (in each case, subject to certain exceptions) to either be reinvested in long-term assets used in the Company’s business or be applied as a mandatory prepayment of the Term Loan.

This royalty excludes production from the recently acquired Paramount properties. The royalty agreement provides for a minimum obligation to be paid monthly on a total of 400,000 ounces of gold, or 4,167 ounces per month over an initial eight year period. Each monthly payment is an amount equal to the greater of 4,167 ounces of gold or 50% of actual gold production multiplied by the excess of the monthly average market price of gold above $412 per ounce, subject to a 1% annual inflation compounding adjustment. Payments under the royalty agreement are made in cash or gold bullion. The Company paid $39.2 million , $48.4 million , and $57.0 million during the years ended December 31, 2015 , 2014 , and 2013, respectively. At December 31, 2015 , payments had been made on a total of 366,505 ounces of gold with further payments to be made on an additional 33,495 ounces of gold. The Company used an implicit interest rate of 30.5% to discount the original royalty obligation, based on the fair value of the consideration received projected over the expected future cash flows at inception of the obligation. The discounted obligation is accreted to its expected future value over the expected minimum payment period based on the implicit interest rate. The Company recognized accretion expense of $6.6 million , $10.8 million , and $17.6 million for the years ended December 31, 2015 , 2014 , and 2013, respectively.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Labor Union Contract The Company maintains a labor agreement with Sindicato de Trabajadores Mineros de la Empresa Manquiri S.A. at the San Bartolomé mine in Bolivia. The San Bartolomé mine labor agreement, which became effective January 28, 2010, is currently active and does not have a fixed term. At December 31, 2015 , approximately 11% of the Company’s global labor force was covered by this collective bargaining agreement. The Company cannot predict whether this agreement will be renewed on similar terms or at all, whether future labor disruptions will occur or, if disruptions do occur, how long they will last. Rochester Production Royalty Commencing January 1, 2014, Coeur Rochester is obligated to pay a 3.4% net smelter returns royalty on up to 39.4 million silver equivalent ounces produced and sold from a portion of the Rochester mine, payable on a quarterly basis. For each calendar quarter, the royalty will be payable on the actual sales prices received (exclusive of gains or losses associated with trading activities), less refining costs, of gold and silver produced and sold from the applicable portions of the Rochester mine. Changes in the Company's mine plan and silver and gold prices result in the recognition of mark-to-market gains or losses in Fair value adjustments, net . At December 31, 2015 , a total of 26.1 million silver equivalent ounces remain outstanding under the obligation. Palmarejo Gold Production Royalty and Gold Stream On January 21, 2009, Coeur Mexicana entered into a gold production royalty agreement with a subsidiary of Franco-Nevada Corporation under which the subsidiary of Franco-Nevada Corporation purchased a royalty covering 50% of the life of mine gold to be produced from its Palmarejo silver and gold mine in Mexico (excluding production from the recently acquired Paramount properties). The royalty agreement provides for a minimum obligation of 4,167 ounces per month over an initial eight-year period for a total of 400,000 ounces of gold. On October 2, 2014 , Coeur Mexicana terminated the Palmarejo gold production royalty in exchange for a termination payment of $2.0 million , effective upon completion of the minimum ounce delivery requirement. Subsequently, Coeur Mexicana entered into a gold stream agreement with a subsidiary of Franco-Nevada Corporation whereby Coeur Mexicana will sell 50% of Palmarejo gold production (excluding production from the recently acquired Paramount properties) upon completion of the gold production royalty minimum ounce delivery requirement for the lesser of $800 or spot price per ounce. Under the gold stream agreement, Coeur Mexicana received a $22.0 million deposit toward future deliveries under the gold stream agreement. Sites Related to Callahan Mining Corporation In 1991, the Company acquired all of the outstanding common stock of Callahan Mining Corporation. The Company has received requests for information or notices of potential liability from state or federal agencies with regard to Callahan's operations at sites in Maine, Colorado and Washington. The Company did not make any decisions with respect to generation, transport or disposal of hazardous waste at these sites. Therefore, the Company believes that it is not liable for any potential cleanup costs either directly as an operator or indirectly as a parent. The Company anticipates that further agency interaction may occur with respect to these sites. Callahan operated a mine and mill in Brooksville, Maine from 1968 until 1972 and subsequently disposed of the property. In 2000, the U.S. Environmental Protection Agency, or EPA, made a formal request to the Company for information regarding the site. The site was placed on the National Priorities List on September 5, 2002, and the Maine Department of Transportation, a partial owner of the property, signed a consent order in 2005. In January 2009, the EPA and the State of Maine made additional formal requests to the Company for information relating to the site, to which the Company responded. The first phase of cleanup at the site began in April 2011. The Van Stone Mine in Stevens County, Washington consists of several parcels of land and was mined from 1926 until 1993 by multiple owners. Callahan sold its parcel in 1990. In February 2010, the State of Washington Department of Ecology notified Callahan that it, among others, is a potentially liable person (PLP) under Washington law. Under lease and option agreements with several owners, Callahan was involved with the Akron Mine located in Gunnison County, Colorado from 1937-1960. The United States Forest Service (“USFS”) made formal requests for information to Callahan regarding the site in December 2003, February 2007, March 2013, and November 2013. Callahan timely responded to each request. In August 2014, Callahan received a notice of potential CERCLA liability from the USFS regarding environmental contamination at the Akron Mine. Callahan and the USFS are currently in discussions regarding this matter. Bolivian Temporary Restriction on Mining above 4,400 Meters On October 14, 2009, the Bolivian state-owned mining organization, COMIBOL, announced by resolution that it was temporarily suspending mining activities above the elevation of 4,400 meters above sea level while stability studies of Cerro Rico mountain are undertaken. The Company holds rights to mine above this elevation under valid contracts with COMIBOL as well as under authorized contracts with local mining cooperatives that hold their rights under contract themselves with COMIBOL. The stability studies have been completed and officially submitted to the Bolivian mining technical authorities. Accordingly, the COMIBOL suspension has expired in accordance with the terms of the resolution. As a result of the resolution, the Company temporarily adjusted its mine plan to confine mining activities to the ore deposits below 4,400 meters above sea level and timely notified COMIBOL of the need to lift the restriction. The Cooperative Reserva Fiscal, with whom the Company has one of those contracts, subsequently interpreted the COMIBOL resolution and determined that the Huacajchi deposit was not covered by such resolution. In March 2010, the Cooperative Reserva Fiscal notified COMIBOL that, based on its interpretation, it was resuming mining of high grade material above the 4,400 meter level in the Huacajchi deposit. In December 2011, the Cooperative Reserva Fiscal sent a similar notification to COMIBOL with respect to a further area above the 4,400 meter level known as Huacajchi Sur. Based on these notifications and on the absence of any objection from COMIBOL, the Company resumed limited mining operations at the San Bartolomé mine on the Huacajchi deposit and Huacajchi Sur. Despite the fact that the COMIBOL suspension has expired, the Company has not resumed mining in other areas above the 4,400 meter level due to community relations concerns and the current political climate in Bolivia. While the COMIBOL suspension has expired, it is uncertain at this time how long the Company will continue to suspend its mining operations in areas above the 4,400 meter level other than at Huacajchi and Huacajchi Sur. If COMIBOL decides to affirmatively adopt a new resolution to restrict access above the 4,400 meter level on a permanent basis, the Company may need to further write down the carrying value of the asset. While a portion of the Company's proven and probable reserves relate to material above the 4,400 meter level at San Bartolomé, so long as operations remain suspended, there is a risk that silver may not be produced from this material at expected levels or at all, particularly given the remaining anticipated mine life of this asset. It is also uncertain if any new mining or investment policies or shifts in political attitude may affect mining in Bolivia.

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The Company's Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles. The preparation of the Company's Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the wholly-owned subsidiaries of the Company, the most significant of which are Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., Wharf Resources (U.S.A.), Empresa Minera Manquiri S.A., and Coeur Capital, Inc. All intercompany balances and transactions have been eliminated. The Company's investments in entities in which it has less than 20% ownership interest are accounted for using the cost method.
Revenue Recognition	Revenue Recognition Revenue is recognized, net of treatment and refining charges, when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, no obligations remain, and collection is probable. Under the Company’s concentrate sales contracts with third-party smelters, gold and silver prices are set on a specified future quotational period, typically one to three months, after the shipment date based on market prices. Revenue and Costs Applicable to Sales are recorded on a gross basis under these contracts at the time title passes to the buyer based on the forward price for the expected settlement period. The contracts, in general, provide for provisional payment based upon provisional assays and forward metal prices. Final settlement is based on the average applicable price for the specified future quotational period and generally occurs from three to six months after shipment. The Company’s provisionally priced sales contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates measured at the forward price at the time of sale. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through revenue each period until the date of final gold and silver settlement.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include all highly-liquid investments with an original maturity of three months or less. The Company minimizes its credit risk by investing its cash and cash equivalents with major U.S. and international banks and financial institutions located principally in the United States with a minimum credit rating of A1, as defined by Standard & Poor’s. The Company’s management believes that no concentration of credit risk exists with respect to the investment of its cash and cash equivalents.
Receivables	Receivables Trade receivables and other receivable balances are reported at outstanding principal amounts, net of an allowance for doubtful accounts, if deemed necessary. Management evaluates the collectability of receivable account balances to determine the allowance, if any. Management considers the other party's credit risk and financial condition, as well as current and projected economic and market conditions, in determining the amount of the allowance. Receivable balances are written off when management determines that the balance is uncollectible.
Ore on Leach Pads	Ore on Leach Pads The heap leach process extracts silver and gold by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained silver and gold, which are then recovered in metallurgical processes. The Company uses several integrated steps to scientifically measure the metal content of ore placed on the leach pads. As the ore body is drilled in preparation for the blasting process, samples are taken of the drill residue which are assayed to determine estimated quantities of contained metal. The Company estimates the quantity of ore by utilizing global positioning satellite survey techniques. The Company then processes the ore through crushing facilities where the output is again weighed and sampled for assaying. A metallurgical reconciliation with the data collected from the mining operation is completed with appropriate adjustments made to previous estimates. The crushed ore is then transported to the leach pad for application of the leaching solution. As the leach solution is collected from the leach pads, it is continuously sampled for assaying. The quantity of leach solution is measured by flow meters throughout the leaching and precipitation process. After precipitation, the product is converted to doré at the Rochester mine and a form of gold concentrate at the Wharf mine, representing the final product produced by each mine. The inventory is stated at lower of cost or market, with cost being determined using a weighted average cost method. The historical cost of metal expected to be extracted within twelve months is classified as current and the historical cost of metals contained within the broken ore expected to be extracted beyond twelve months is classified as non-current. Ore on leach pads is valued based on actual production costs incurred to produce and place ore on the leach pad, less costs allocated to minerals recovered through the leach process. The estimate of both the ultimate recovery expected over time and the quantity of metal that may be extracted relative to the time the leach process occurs requires the use of estimates, which are inherently inaccurate due to the nature of the leaching process. The quantities of metal contained in the ore are based upon actual weights and assay analysis. The rate at which the leach process extracts gold and silver from the crushed ore is based upon laboratory testing and actual experience of more than twenty years of leach pad operations at the Rochester mine and thirty years of leach pad operations at the Wharf mine. The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis.
Metal and Other Inventory	Metal and Other Inventory Inventories include concentrate, doré, and operating materials and supplies. The classification of inventory is determined by the stage at which the ore is in the production process. All inventories are stated at the lower of cost or market, with cost being determined using a weighted average cost method. Concentrate and doré inventory includes product at the mine site and product held by refineries. Metal inventory costs include direct labor, materials, depreciation, depletion and amortization as well as overhead costs relating to mining activities.
Property, Plant and Equipment	Property, Plant, and Equipment Expenditures for new facilities, assets acquired pursuant to capital leases, new assets or expenditures that extend the useful lives of existing facilities are capitalized and depreciated using the straight-line method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such facilities, lease term, or the useful life of the individual assets. Productive lives range from 7 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Certain mining equipment is depreciated using the units-of-production method based upon estimated total proven and probable reserves.
Mining Properties and Mine Development	Mining Properties and Mine Development Capitalization of mine development costs begins once all operating permits have been secured, mineralization is classified as proven and probable reserves and a final feasibility study has been completed. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Costs incurred before mineralization are classified as proven and probable reserves are expensed and classified as exploration or pre-development expense. Mine development costs are amortized using the units of production method over the estimated life of the ore body based on recoverable ounces to be mined from proven and probable reserves. Interest expense allocable to the cost of developing mining properties and to construct new facilities is capitalized until assets are ready for their intended use. Drilling and related costs incurred at the Company’s operating mines are expensed as incurred in Exploration, unless the Company can conclude with a high degree of confidence, prior to the commencement of a drilling program, that the drilling costs will result in the conversion of a mineral resource into proven and probable reserves. The Company’s assessment is based on the following factors: results from previous drill programs; results from geological models; results from a mine scoping study confirming economic viability of the resource; and preliminary estimates of mine inventory, ore grade, cash flow and mine life. In addition, the Company must have all permitting and/or contractual requirements necessary to have the right to and/or control of the future benefit from the targeted ore body. The costs of a drilling program that meet these criteria are capitalized as mine development costs. Drilling and related costs of approximately $6.0 million and $8.9 million at December 31, 2015 and 2014, respectively, were capitalized. The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Costs applicable to sales in the same period as the revenue from the sale of inventory.
Mineral Interests	Mineral Interests Significant payments related to the acquisition of land and mineral rights are capitalized. Prior to acquiring such land or mineral rights, the Company generally makes a preliminary evaluation to determine that the property has significant potential to develop an economic ore body. The time between initial acquisition and full evaluation of a property’s potential is variable and is determined by many factors including: location relative to existing infrastructure, the property’s stage of development, geological controls and metal prices. If a mineable ore body is discovered, such costs are amortized when production begins using the units-of-production method based on recoverable ounces to be mined from proven and probable reserves. If no mineable ore body is discovered, such costs are expensed in the period in which it is determined the property has no future economic value.
Write-downs	Write-downs We review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated undiscounted pre-tax future cash flows are less than the carrying amount of the asset. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of future cash flows from other asset groups. An impairment loss is measured by discounted estimated future cash flows, and recorded by reducing the asset's carrying amount to fair value. Future cash flows are estimated based on estimated quantities of recoverable minerals, expected silver and gold prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. The significant assumptions used in determining future cash flows for each mine site asset group at December 31, 2015, apart from production cost and capitalized expenditure assumptions unique to each operation, included long-term silver and gold prices of $17.50 and $1,200 per ounce (consistent with the Company’s long-term reserve prices), respectively, and discount rates ranging from 7.50% - 11.00% (to reflect project and country-specific risks). During 2015, 2014, and 2013, we recorded impairments of $313.3 million , $1,472.7 million , and $773.0 million , respectively, to reduce the carrying value of mining properties and property, plant and equipment as part of Write-downs. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization other than proven and probable reserves are included when determining the fair value of mine site asset groups at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of silver and gold that will be obtained after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from exploration stage mineral interests are risk adjusted based on management’s relative confidence in such materials. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those risk factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material could ultimately be mined economically. Assets classified as exploration potential have the highest level of risk that the carrying value of the asset can be ultimately realized, due to the still lower level of geological confidence and economic modeling. Silver and gold prices are volatile and affected by many factors beyond the Company’s control, including prevailing interest rates and returns on other asset classes, expectations regarding inflation, speculation, currency values, governmental decisions regarding precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors may affect the key assumptions used in the Company’s impairment testing. Various factors could impact our ability to achieve forecasted production levels from proven and probable reserves. Additionally, production, capital and reclamation costs could differ from the assumptions used in the cash flow models used to assess impairment. Actual results may vary from the Company’s estimates and result in additional Write-downs .
Restricted Assets	Restricted Assets The Company, under the terms of its self-insurance and bonding agreements with certain banks, lending institutions and regulatory agencies, is required to collateralize certain portions of its obligations. The Company has collateralized these obligations by assigning certificates of deposit that have maturity dates ranging from three months to a year, to the respective institutions or agencies. At December 31, 2015 and 2014, the Company held certificates of deposit and cash under these agreements of $6.3 million and $7.0 million , respectively. The ultimate timing of the release of the collateralized amounts is dependent on the timing and closure of each mine and repayment of the facility. In order to release the collateral, the Company must seek approval from certain government agencies responsible for monitoring the mine closure status. Collateral could also be released to the extent the Company is able to secure alternative financial assurance satisfactory to the regulatory agencies. The Company believes there is a reasonable probability that the collateral will remain in place beyond a twelve-month period and has therefore classified these investments as long-term.
Reclamation	Reclamation The Company recognizes obligations for the expected future retirement of tangible long-lived assets and other associated asset retirement costs. The fair value of a liability for an asset retirement obligation will be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period in Pre-development, reclamation, and other . As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced. Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the discounted costs expected to be incurred at the site. Such cost estimates include, where applicable, ongoing care and maintenance and monitoring costs. Changes in estimates are reflected prospectively in the period an estimate is revised.
Foreign Currency	Foreign Currency The assets and liabilities of the Company’s foreign subsidiaries are measured using U.S. dollars as their functional currency. Revenues and expenses are translated at the average exchange rate for the period. Foreign currency gains and losses are included in the determination of net income or loss.
Derivative Financial Instruments	Derivative Financial Instruments The Company recognizes all derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in the value of derivative instruments are recorded each period in the Consolidated Statement of Comprehensive Income (Loss) in Fair value adjustments, net . Management applies judgment in estimating the fair value of instruments that are highly sensitive to assumptions regarding commodity prices, market volatilities, and foreign currency exchange rates.
Stock-based Compensation Plans	Stock-based Compensation Plans The Company estimates the fair value of stock options using the Black-Scholes option pricing model and stock appreciation rights (“SARs”) awards using market comparison. Stock options granted are accounted for as equity-based awards and SARs are accounted for as liability-based awards. The value of the SARs is remeasured at each reporting date. The Company estimates the fair value of performance share and performance unit grants using a Monte Carlo simulation valuation model. Performance shares granted are accounted for as equity based awards and performance shares units are accounted for as liability-based awards. The Company estimates forfeitures of stock-based awards based on historical data and periodically adjusts the forfeiture rate. The adjustment of the forfeiture rate is recorded as a cumulative adjustment in the period the forfeiture estimate is changed. Compensation costs related to stock based compensation are included in General and administrative expenses , Costs applicable to sales , and Property, plant, and equipment, net as deemed appropriate. Restricted stock and restricted stock units granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant. Restricted stock awards are accounted for as equity-based awards and restricted stock unit awards are accounted for as liability-based awards. Restricted stock units are remeasured at each reporting date. Restricted stock units are settled in cash based on the number of vested restricted stock units multiplied by the current market price of the common shares when vested. Holders of the restricted stock are entitled to vote the shares and to receive any dividends declared on the shares.
Income and Mining Taxes	Income and Mining Taxes The Company uses an asset and liability approach which results in the recognition of deferred tax liabilities and assets for the expected future tax consequences or benefits of temporary differences between the financial reporting basis and the tax basis of assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. A valuation allowance has been provided for the portion of the Company’s net deferred tax assets for which it is more likely than not that they will not be realized.
Recent Accounting Standards	Recent Accounting Standards In November 2015, the FASB issued ASU 2015-17, "Balance Sheet Classification of Deferred Taxes," which requires entities with a classified balance sheet to present all deferred tax assets and liabilities as non-current. The updated guidance became effective under early adoption for the Company's fiscal year beginning January 1, 2015, and resulted in a reclassification of amounts from Current deferred tax assets to Non-current deferred tax assets and Current deferred tax liabilities to Non-current deferred tax liabilities in the current and prior periods. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. These changes become effective for the Company's fiscal year beginning January 1, 2016. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows. In August 2015, the FASB issued ASU 2015-14, "Deferral of the Effective Date" , which defers the effective date of ASU 2014-09, "Revenue from Contracts with Customers" to January 1, 2018. The Company is currently evaluating the potential impact of adopting the prescribed changes on the Company's consolidated financial position, results of operations, and cash flows. In July 2015, the FASB issued ASU 2015-11, " Simplifying the Measurement of Inventory," which provides a revised, simpler measurement for inventory to be measured at the lower of cost and net realizable value. These changes become effective for the Company's fiscal year beginning January 1, 2018. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows. In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," which requires that debt issuance costs related to a recognized debt liability be presented as a reduction to the carrying amount of that debt liability, not as an asset. The updated guidance became effective under early adoption for the Company's fiscal year beginning January 1, 2015, and resulted in a reclassification of amounts from Other Non-current Assets to Debt in the current and prior periods. In February 2015, the FASB issued ASU 2015-02, "Amendments to the Consolidation Analysis," which amends the consolidation requirements in ASC 810. These changes become effective for the Company's fiscal year beginning January 1, 2016. The Company is currently evaluating the potential impact of implementing these changes on the Company's consolidated financial position, results of operations, and cash flows.

The Company then sells its silver and gold bullion to multi-national banks, bullion trading houses, and refiners across the globe. The Company has eleven trading counterparties and the sales of metals to these companies amounted to approximately 74% , 63% , and 72% of total metal sales for the years ended December 31, 2015, 2014, and 2013, respectively. Generally, the loss of a single bullion trading counterparty would not adversely affect the Company due to the liquidity of the markets and the availability of alternative trading counterparties. The Company's concentrate produced by the Kensington mine is sold to smelters under purchase and sale agreements, and the smelters pay the Company for the gold or silver recovered from the concentrates. The Company currently sells concentrate to three smelters, and sales to these companies amounted to approximately 26% , 37% , and 28% of total metal sales for the years ended December 31, 2015, 2014, and 2013, respectively. While the loss of any one smelter may have a material adverse effect if alternate smelters are not available, the Company believes that there is sufficient global capacity available to address the loss of a smelter. The following table indicates customers that represent 10% or more of total sales of metal for at least one of the years December 31, 2015, 2014, and 2013 (in millions): Years Ended December 31, Customer 2015 2014 2013 Segments reporting revenue Mitsui & Co. $ 137.7 $ 133.8 $ 70.3 Palmarejo, Rochester China National Gold 126.2 86.8 81.5 Kensington Asahi (formerly Johnson Matthey) 84.2 71.8 66.4 Wharf, Rochester, San Bartolomé TD Securities 81.3 106.7 106.7 Palmarejo, Rochester Standard Bank 34.7 87.5 69.0 Palmarejo, Rochester INTL Commodities 33.1 22.4 84.6 Palmarejo, San Bartolomé, Rochester Valcambi — 33.9 77.2 Palmarejo, San Bartolomé Auramet — 10.8 111.7 Palmarejo, San Bartolomé, Kensington, Rochester
