Accounting Policies [Abstract]
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 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, marketable 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 Empresa Minera Manquiri S.A., Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., and Coeur Capital. All significant 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. Revenues and production 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, which is the final product produced by the mine. The inventory is stated at lower of cost or market, with cost being determined using a weighted average cost method. The Company reported ore on the leach pads of $82.0 million as of December 31, 2013, and $44.3 million as of December 31, 2012. As of December 31, 2013, $50.5 million is reported as a current asset and $31.5 million is reported as a non-current asset. As of December 31, 2012, $23.0 million is reported as a current asset and $21.4 million is reported as a non-current asset. The historical cost of the metal that is expected to be extracted within twelve months is classified as current and the historical cost of metals contained within the broken ore that is expected to be extracted beyond twelve months is classified as non-current. Ore on leach pad 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 column tests and actual experience occurring over more than twenty years of leach pad operations at the Rochester 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. Concentrate inventories associated with the Endeavor mine are held by third parties. 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 31 years for buildings and improvements and 3 to 13 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 is 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 as exploration expense, 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 $11.6 million and $13.9 million at December 31, 2013 and 2012, 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 production 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. Asset Impairment Management reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. Impairment is considered to exist if the total probability-weighted estimate or other appropriate estimate of future cash flows on an undiscounted basis are less than the carrying amount of the asset group, including property plant and equipment, mineral property, development property, and any deferred costs. An impairment loss is measured and recorded based on the difference between book value and estimated fair value of the asset group. Future cash flows include estimates of recoverable ounces, gold and silver prices (considering current and historical prices, price trends and related factors), production levels and required capital investment, all based on life-of-mine plans and projections. Assumptions underlying future cash flow estimates are subject to risks and uncertainties. Any differences between these assumptions and actual market conditions or the Company’s actual operating performance could have a material effect on the Company’s determination of its ability to recover the carrying amounts of its long-lived assets resulting in impairment charges. In estimating future cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of cash flows from other asset groups. Generally, in estimating future cash flows, all assets are grouped at a particular mine for which there is identifiable cash flow. 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, 2013 and 2012, the Company held certificates of deposit and cash under these agreements of $7.0 million and $25.0 million, respectively, restricted for these purposes. 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 and Remediation Costs 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 Amortization expense. 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 undiscounted 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 transaction 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 and stock appreciation rights (“SARs”) awards using the Black-Scholes option pricing model. 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, Production costs applicable to sales and the cost of self-constructed property, plant and equipment 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 and vest in equal installments annually over three years. 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 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 Certain immaterial amounts in prior years have been corrected to conform to current presentation. The Company reclassified certain income-based state taxes from Production costs applicable to sales to Income tax provision (benefit). Recent Accounting Standards On January 1, 2013, the Company adopted ASU 2011-11, "Balance Sheet (Topic 201): Disclosures about Offsetting Assets and Liabilities." This ASU adds certain additional disclosure requirements about financial instruments and derivative instruments that are subject to netting arrangements. The adoption of ASU 2011-11 had no effect on the Company's financial position, results of operations or cash flows. On January 1, 2013, the Company adopted ASU 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." The new standard requires either in a single note or parenthetically on the face of the financial statements: (i) the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and (ii) the income statement line items affected by the reclassification. The adoption of ASU 2013-02 had no effect on the Company's financial position, results of operations or cash flows. In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." The updated guidance requires an entity to net its unrecognized tax benefits against the deferred tax assets for all same jurisdiction net operating loss carryforwards, a similar tax loss, or tax credit carryforwards. A gross presentation will be required only if such carryforwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax provision. The update is effective prospectively for the Company's fiscal year beginning January 1, 2014.

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 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, marketable 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 Empresa Minera Manquiri S.A., Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., and Coeur Capital. All significant 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. Revenues and production 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.

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 31 years for buildings and improvements and 3 to 13 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 is classified as proven and probable reserves are expensed and classified as Exploration or Pre-development expense.

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 production 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.

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.

Asset Impairment

Management reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. Impairment is considered to exist if the total probability-weighted estimate or other appropriate estimate of future cash flows on an undiscounted basis are less than the carrying amount of the asset group, including property plant and equipment, mineral property, development property, and any deferred costs. An impairment loss is measured and recorded based on the difference between book value and estimated fair value of the asset group. Future cash flows include estimates of recoverable ounces, gold and silver prices (considering current and historical prices, price trends and related factors), production levels and required capital investment, all based on life-of-mine plans and projections. Assumptions underlying future cash flow estimates are subject to risks and uncertainties. Any differences between these assumptions and actual market conditions or the Company’s actual operating performance could have a material effect on the Company’s determination of its ability to recover the carrying amounts of its long-lived assets resulting in impairment charges.

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 Amortization expense. 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 undiscounted 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 transaction 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 and stock appreciation rights (“SARs”) awards using the Black-Scholes option pricing model. 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, Production costs applicable to sales and the cost of self-constructed property, plant and equipment 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 and vest in equal installments annually over three years. 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 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

Certain immaterial amounts in prior years have been corrected to conform to current presentation. The Company reclassified certain income-based state taxes from Production costs applicable to sales to Income tax provision (benefit).

On January 1, 2013, the Company adopted ASU 2011-11, "Balance Sheet (Topic 201): Disclosures about Offsetting Assets and Liabilities." This ASU adds certain additional disclosure requirements about financial instruments and derivative instruments that are subject to netting arrangements. The adoption of ASU 2011-11 had no effect on the Company's financial position, results of operations or cash flows.

On January 1, 2013, the Company adopted ASU 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." The new standard requires either in a single note or parenthetically on the face of the financial statements: (i) the effect of significant amounts reclassified from each component of accumulated other comprehensive income based on its source and (ii) the income statement line items affected by the reclassification. The adoption of ASU 2013-02 had no effect on the Company's financial position, results of operations or cash flows.

In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists." The updated guidance requires an entity to net its unrecognized tax benefits against the deferred tax assets for all same jurisdiction net operating loss carryforwards, a similar tax loss, or tax credit carryforwards. A gross presentation will be required only if such carryforwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax provision. The update is effective prospectively for the Company's fiscal year beginning January 1, 2014.
