Significant Accounting Policies (Policies)	12 Months Ended
Dec. 31, 2012
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Consolidated Financial Statements include Libbey Inc. and its majority-owned subsidiaries (collectively, Libbey or the Company). Our fiscal year end is December 31^st. All material intercompany accounts and transactions have been eliminated. The preparation of financial statements and related disclosures in conformity with United States generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ materially from management’s estimates.
Consolidated Statement of Operations	Consolidated Statements of Operations Net sales in our Consolidated Statements of Operations include revenue earned when products are shipped and title and risk of loss have passed to the customer. Revenue is recorded net of returns, discounts and incentives offered to customers. Cost of sales includes cost to manufacture and/or purchase products, warehouse, shipping and delivery costs and other costs.
Revenue Recognition	Revenue Recognition Revenue is recognized when products are shipped and title and risk of loss have passed to the customer. Revenue is recorded net of returns, discounts and incentives offered to customers. We estimate returns, discounts and incentives at the time of sale based on the terms of the agreements, historical experience and forecasted sales. We continually evaluate the adequacy of these methods used to estimate returns, discounts and incentives.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained with various financial institutions.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts We record trade receivables when revenue is recorded in accordance with our revenue recognition policy and relieve accounts receivable when payments are received from customers. The allowance for doubtful accounts is established through charges to the provision for bad debts. We regularly evaluate the adequacy of the allowance for doubtful accounts based on historical trends in collections and write-offs, our judgment as to the probability of collecting accounts and our evaluation of business risk. This evaluation is inherently subjective, as it requires estimates that are susceptible to revision as more information becomes available. Accounts are determined to be uncollectible when the debt is deemed to be worthless or only recoverable in part and are written off at that time through a charge against the allowance.
Inventory Valuation	Inventory Valuation Inventories are valued at the lower of cost or market. The last-in, first-out (LIFO) method is used for our U.S. glass inventories, which represented 30.6 percent and 31.3 percent of our total inventories in 2012 and 2011, respectively. The remaining inventories are valued using either the first-in, first-out (FIFO) or average cost method. For those inventories valued on the LIFO method, the excess of FIFO cost over LIFO, was $15.0 million and $15.7 million in 2012 and 2011, respectively. Cost includes the cost of materials, direct labor, in-bound freight and the applicable share of manufacturing overhead.
Purchased Intangible Assets and Goodwill	Purchased Intangible Assets and Goodwill Financial Accounting Standards Board Accounting Standards Codification™ ("FASB ASC") Topic 350 - "Intangibles-Goodwill and other" ("FASB ASC 350") requires goodwill and purchased indefinite life intangible assets to be reviewed for impairment annually, or more frequently if impairment indicators arise. Intangible assets with lives restricted by contractual, legal or other means will continue to be amortized over their useful lives. As of October 1st of each year, we update our separate impairment evaluations for both goodwill and indefinite life intangible assets.
Software	Software We account for software in accordance with FASB ASC 350. Software represents the costs of internally developed and purchased software packages for internal use. Capitalized costs include software packages, installation and/or internal labor costs. These costs generally are amortized over a five-year period.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally 3 to 14 years for equipment and furnishings and 10 to 40 years for buildings and improvements. Maintenance and repairs are expensed as incurred. Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Measurement of an impairment loss for long-lived assets that we expect to hold and use is based on the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Self-Insurance Reserves	Self-Insurance Reserves Self-Insurance reserves reflect the estimated liability for group health and workers' compensation claims not covered by third-party insurance. We accrue estimated losses based on actuarial models and assumptions as well as our historical loss experience. Workers' compensation accruals are recorded at the estimated ultimate payout amounts based on individual case estimates. In addition, we record estimates of incurred-but-not-reported losses based on actuarial models.
Pension and Nonpension Postretirement Benefits	Pension and Nonpension Postretirement Benefits We account for pension and nonpension postretirement benefits in accordance with FASB ASC Topic 758 - "Compensation-Retirement Plans" ("FASB ASC 758"). FASB ASC 758 requires recognition of the over-funded or under-funded status of pension and other postretirement benefit plans on the balance sheet. Under FASB ASC 758, gains and losses, prior service costs and credits and any remaining prior transaction amounts that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive loss, net of tax effect where appropriate. The U.S. pension plans cover most hourly U.S.-based employees (excluding new hires at Shreveport after 2008 and at Toledo after September 30, 2010) and those salaried U.S.-based employees hired before January 1, 2006. U.S. salaried employees are not eligible for additional company contribution credits after December 31, 2012. The non-U.S. pension plans cover the employees of our wholly-owned subsidiaries in the Netherlands and Mexico. For further discussion see note 9. We also provide certain postretirement health care and life insurance benefits covering substantially all U.S. and Canadian salaried and non-union hourly employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, the existing healthcare benefit for salaried retirees age 65 and older ceased. We now provide a Retiree Health Reimbursement Arrangement (RHRA) that supports salaried retirees in purchasing a Medicare plan that meets their needs. Also effective January 1, 2013, we reduced the maximum life insurance benefit for salaried retirees to $10,000. Employees are generally eligible for benefits upon reaching a certain age and completion of a specified number of years of creditable service. Benefits for most hourly retirees are determined by collective bargaining. Under a cross-indemnity agreement, Owens-Illinois, Inc. assumed liability for the nonpension postretirement benefit of our retirees who had retired as of June 24, 1993. Therefore, the benefits related to these retirees are not included in our liability.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax attribute carry-forwards. Deferred income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. FASB ASC Topic 740, “Income Taxes,” requires that a valuation allowance be recorded when it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred income tax assets and liabilities are determined separately for each tax jurisdiction in which we conduct our operations or otherwise incur taxable income or losses. In the United States, Portugal and the Netherlands, we have recorded valuation allowances against our deferred income tax assets. We are subject to income taxes in the U.S. and various foreign jurisdictions. Management judgment is required in evaluating our tax positions and determining our provision for income taxes. Throughout the course of business, there are numerous transactions and calculations for which the ultimate tax determination is uncertain. When management believes certain tax positions may be challenged despite our belief that the tax return positions are supportable, we establish reserves for tax uncertainties based on estimates of whether additional taxes will be due. We adjust these reserves taking into consideration changing facts and circumstances, such as an outcome of a tax audit. The income tax provision includes the impact of reserve provisions and changes to reserves that are considered appropriate. Accruals for tax contingencies are provided for in accordance with the requirements of FASB ASC 740. In assessing the need for a valuation allowance, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will be realized on a quarterly basis or whenever events indicate that a review is required. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income (including reversals of deferred income tax liabilities) during the periods in which those temporary differences reverse. As a result, we consider the historical and projected financial results of the legal entity or consolidated group recording the net deferred income tax asset as well as all other positive and negative evidence. Examples of the evidence we consider are cumulative losses in recent years, losses expected in early future years, a history of potential tax benefits expiring unused and whether there was an unusual, infrequent, or extraordinary item to be considered.
Derivatives	Derivatives We account for derivatives in accordance with FASB ASC Topic 815 "Derivatives and Hedging" ("FASB ASC 815"). We hold derivative financial instruments to hedge certain of our interest rate risks associated with long-term debt, commodity price risks associated with forecasted future natural gas requirements and foreign exchange rate risks associated with occasional transactions denominated in a currency other than the U.S. dollar. These derivatives (except for the foreign currency contracts) qualify for hedge accounting since the hedges are highly effective, and we have designated and documented contemporaneously the hedging relationships involving these derivative instruments. While we intend to continue to meet the conditions for hedge accounting, if hedges do not qualify as highly effective or if we do not believe that forecasted transactions would occur, the changes in the fair value of the derivatives used as hedges would be reflected in earnings. Cash flows from fair value hedges of debt and short-term forward exchange contracts are classified as an operating activity. Cash flows of currency swaps, interest rate swaps, and commodity futures contracts are classified as operating activities.
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where that local currency is the functional currency, are translated to U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive loss. Income and expense accounts are translated at average exchange rates during the year. The effect of exchange rate changes on transactions denominated in currencies other than the functional currency is recorded in other income (expense).
Stock-Based Compensation Expense	Stock-Based Compensation Expense We account for stock-based compensation expense in accordance with FASB ASC Topic 718, “Compensation — Stock Compensation,” ("FASB ASC 718") and FASB ASC Topic 505-50, “Equity-Based Payments to Non-Employees”("FASB ASC 505-50"). Stock-based compensation cost is measured based on the fair value of the equity instruments issued. FASB ASC Topics 718 and 505-50 apply to all of our outstanding unvested stock-based payment awards.
Research and Development	Research and Development Research and development costs are charged to selling, general and administrative expense in the Consolidated Statements of Operations when incurred.
Advertising Costs	Advertising Costs We expense all advertising costs as incurred, and the amounts were immaterial for all periods presented.
Treasury Stock	Treasury Stock Treasury stock purchases are recorded at cost.
New Accounting Standards	New Accounting Standards In May 2011, the FASB issued Accounting Standards Update 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). ASU 2011-04 explains how to measure fair value and improves the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRS. ASU 2011-04 does not require additional fair value measurements, and it is not intended to establish valuation standards or affect valuation practices outside of financial reporting. The provisions of this update are effective for periods beginning after December 15, 2011. The provisions of this update did not have any impact on our Consolidated Financial Statements. In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (ASU 2011-05). This ASU requires companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. This guidance is effective for fiscal years and interim periods beginning after December 15, 2011 with early adoption permitted. In December 2011, ASU 2011-05 was modified by the issuance of Accounting Standards Update 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (ASU 2011-12) which defers certain paragraphs of ASU 2011-05 that would require reclassifications of items from other comprehensive income to net income by component of net income and by component of other comprehensive income. We have made all of the required disclosures within our Consolidated Financial Statements. In July 2012, the FASB issued Accounting Standards Update 2012-02, “Intangibles — Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02). ASU 2012-02 allows for an option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the indefinite-lived intangible asset exceeds its carrying amount. If the qualitative factors result in the fair value exceeding the carrying value of the indefinite-lived intangible asset, then the fair value does not need to be calculated. This update is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The provisions of this update did not have any impact on our Consolidated Financial Statements. In February 2013, the FASB issued Accounting Standards Update 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02), which amends Topic 220 Comprehensive Income. ASU 2013-02 requires companies to present, either in a note or parenthetically on the face of the financial statements, the effect of amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. This update is effective for interim and annual reporting periods beginning after December 15, 2012. We will include the additional disclosures in our Consolidated Financial Statements beginning on January 1, 2013.
Indefinite Life Intangible Assets	Indefinite life intangible assets are composed of trade names and trademarks that have an indefinite life and are therefore individually tested for impairment on an annual basis, or more frequently in certain circumstances where impairment indicators arise, in accordance with FASB ASC 350. Our measurement date for impairment testing is October 1st of each year. When performing our test for impairment of individual indefinite life intangible assets, we use a relief from royalty method to determine the fair market value that is compared to the carrying value of the indefinite life intangible asset. The inputs used for this analysis are considered as Level 3 inputs in the fair value hierarchy. See note 15 for further discussion of the fair value hierarchy.
Goodwill	Goodwill impairment tests are completed for each reporting unit on an annual basis, or more frequently in certain circumstances where impairment indicators arise. The inputs used for this analysis are considered as Level 3 inputs in the fair value hierarchy. See note 15 for further discussion of the fair value hierarchy. When performing our test for impairment, we use an approach which includes a discounted cash flow analysis, incorporating the weighted average cost of capital of a hypothetical third party buyer to compute the fair value of each reporting unit. The fair value is then compared to the carrying value. To the extent that fair value exceeds the carrying value, no impairment exists. However, to the extent the carrying value exceeds the fair value, we compare the implied fair value of goodwill to its book value to determine if an impairment should be recorded.
Pensions	The discount rate enables us to estimate the present value of expected future cash flows on the measurement date. The rate used reflects a rate of return on high-quality fixed income investments that match the duration of expected benefit payments at our December 31 measurement date. The discount rate at December 31 is used to measure the year-end benefit obligations and the earnings effects for the subsequent year. A higher discount rate decreases the present value of benefit obligations and decreases pension expense. To determine the expected long-term rate of return on plan assets for our funded plans, we consider the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. The expected long-term rate of return on plan assets at December 31^st is used to measure the earnings effects for the subsequent year. The assumed long-term rate of return on assets is applied to a calculated value of plan assets that recognizes gains and losses in the fair value of plan assets compared to expected returns over the next five years. This produces the expected return on plan assets that is included in pension expense. The difference between the expected return and the actual return on plan assets is deferred and amortized over five years. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension expense (income). Future benefits are assumed to increase in a manner consistent with past experience of the plans except for the Libbey U.S. Salaried Pension Plan and SERP as discussed above, which, to the extent benefits are based on compensation, includes assumed compensation increases as presented above. Amortization included in net pension expense is based on the average remaining service of employees. We account for our defined benefit pension plans on an expense basis that reflects actuarial funding methods. The actuarial valuations require significant estimates and assumptions to be made by management, primarily with respect to the discount rate and expected long-term return on plan assets. These assumptions are all susceptible to changes in market conditions. The discount rate is based on a selected settlement portfolio from a universe of high quality bonds. In determining the expected long-term rate of return on plan assets, we consider historical market and portfolio rates of return, asset allocations and expectations of future rates of return. We evaluate these critical assumptions on our annual measurement date of December 31st. Other assumptions involving demographic factors such as retirement age, mortality and turnover are evaluated periodically and are updated to reflect our experience. Actual results in any given year often will differ from actuarial assumptions because of demographic, economic and other factors. We have pension plans covering the majority of our employees. Benefits generally are based on compensation and service for salaried employees and job grade and length of service for hourly employees. Our policy is to fund pension plans such that sufficient assets will be available to meet future benefit requirements. In addition, we have an unfunded supplemental employee retirement plan (SERP) that covers salaried U.S.-based employees of Libbey hired before January 1, 2006. The U.S. pension plans cover the salaried U.S.-based employees of Libbey hired before January 1, 2006 and most hourly U.S.-based employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, we are ceasing annual company contribution credits to the cash balance accounts in our Libbey U.S. Salaried Pension Plan and SERP. The non-U.S. pension plans cover the employees of our wholly owned subsidiaries in the Netherlands and Mexico. The plan in Mexico is not funded.
Nonpension Postretirement Benefits	We provide certain retiree health care and life insurance benefits covering our U.S. and Canadian salaried and non-union hourly employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. Effective January 1, 2013, we are ending our existing healthcare benefit for salaried retirees age 65 and older and will instead provide a Retiree Health Reimbursement Arrangement (RHRA) that supports retirees in purchasing a Medicare plan that meets their needs. Also effective January 1, 2013, we are reducing the maximum life insurance benefit for salaried retirees to $10,000. Benefits for most hourly retirees are determined by collective bargaining. The U.S. nonpension postretirement plans cover the hourly and salaried U.S.-based employees of Libbey. The non-U.S. nonpension postretirement plans cover the retirees and active employees of Libbey who are located in Canada. The postretirement benefit plans are not funded.
Computation of Income Per Share of Common Stock	Computation of Income Per Share of Common Stock Basic net income per share of common stock is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share of common stock is computed using the weighted average number of shares of common stock outstanding and dilutive potential common share equivalents during the period. When applicable, diluted shares outstanding include the dilutive impact of warrants and restricted stock units. Diluted shares also include the impact of in-the-money employee stock options, which are calculated based on the average share price for each fiscal period using the treasury stock method. Under the treasury stock method, the tax-effected proceeds that hypothetically would be received from the exercise of all in-the-money options are assumed to be used to repurchase shares.
Fair Value	The fair values of our commodity futures natural gas contracts and currency contracts are determined using observable market inputs. The fair value of our interest rate agreement is based on the market standard methodology of netting the discounted expected future fixed cash receipts and the discounted future variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observed market interest rate forward curves. Since these inputs are observable in active markets over the terms that the instruments are held, the derivatives are classified as Level 2 in the hierarchy. We also evaluate Company and counterparty risk in determining fair values. The commodity futures natural gas contracts, interest rate protection agreements and currency contracts are hedges of either recorded assets or liabilities or anticipated transactions.
Segments	Our measure of profit for our reportable segments is Segment Earnings before Interest and Taxes (Segment EBIT) and excludes amounts related to certain items we consider not representative of ongoing operations as well as certain retained corporate costs. We use Segment EBIT, along with net sales and selected cash flow information, to evaluate performance and to allocate resources. Segment EBIT for reportable segments includes an allocation of some corporate expenses based on both a percentage of sales and direct billings based on the costs of services performed. Certain activities not related to any particular reportable segment are reported within retained corporate costs. These costs include certain headquarter, administrative and facility costs, and other costs that are global in nature and are not allocable to the reporting segments. Corporate assets primarily include finance fees, capitalized software, and income tax assets. The accounting policies of the reportable segments are the same as those described in note 2. We do not have any customers who represent 10 percent or more of total sales. We evaluate the performance of our segments based upon sales and Segment Segment EBIT. Inter-segment sales are consummated at arm’s length and are reflected in eliminations below.

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Basis of Presentation The Consolidated Financial Statements include Libbey Inc. and its majority-owned subsidiaries (collectively, Libbey or the Company). Our fiscal year end is December 31^st. All material intercompany accounts and transactions have been eliminated. The preparation of financial statements and related disclosures in conformity with United States generally accepted accounting principles (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results could differ materially from management’s estimates.

Consolidated Statement of Operations

Consolidated Statements of Operations Net sales in our Consolidated Statements of Operations include revenue earned when products are shipped and title and risk of loss have passed to the customer. Revenue is recorded net of returns, discounts and incentives offered to customers. Cost of sales includes cost to manufacture and/or purchase products, warehouse, shipping and delivery costs and other costs.

Revenue Recognition

Revenue Recognition Revenue is recognized when products are shipped and title and risk of loss have passed to the customer. Revenue is recorded net of returns, discounts and incentives offered to customers. We estimate returns, discounts and incentives at the time of sale based on the terms of the agreements, historical experience and forecasted sales. We continually evaluate the adequacy of these methods used to estimate returns, discounts and incentives.

Cash and Cash Equivalents

Cash and Cash Equivalents We consider all highly liquid investments purchased with an original or remaining maturity of less than three months at the date of purchase to be cash equivalents. Cash and cash equivalents are maintained with various financial institutions.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts We record trade receivables when revenue is recorded in accordance with our revenue recognition policy and relieve accounts receivable when payments are received from customers. The allowance for doubtful accounts is established through charges to the provision for bad debts. We regularly evaluate the adequacy of the allowance for doubtful accounts based on historical trends in collections and write-offs, our judgment as to the probability of collecting accounts and our evaluation of business risk. This evaluation is inherently subjective, as it requires estimates that are susceptible to revision as more information becomes available. Accounts are determined to be uncollectible when the debt is deemed to be worthless or only recoverable in part and are written off at that time through a charge against the allowance.

Inventory Valuation

Inventory Valuation Inventories are valued at the lower of cost or market. The last-in, first-out (LIFO) method is used for our U.S. glass inventories, which represented 30.6 percent and 31.3 percent of our total inventories in 2012 and 2011, respectively. The remaining inventories are valued using either the first-in, first-out (FIFO) or average cost method. For those inventories valued on the LIFO method, the excess of FIFO cost over LIFO, was $15.0 million and $15.7 million in 2012 and 2011, respectively. Cost includes the cost of materials, direct labor, in-bound freight and the applicable share of manufacturing overhead.

Purchased Intangible Assets and Goodwill

Purchased Intangible Assets and Goodwill Financial Accounting Standards Board Accounting Standards Codification™ ("FASB ASC") Topic 350 - "Intangibles-Goodwill and other" ("FASB ASC 350") requires goodwill and purchased indefinite life intangible assets to be reviewed for impairment annually, or more frequently if impairment indicators arise. Intangible assets with lives restricted by contractual, legal or other means will continue to be amortized over their useful lives. As of October 1st of each year, we update our separate impairment evaluations for both goodwill and indefinite life intangible assets.

Software

Software We account for software in accordance with FASB ASC 350. Software represents the costs of internally developed and purchased software packages for internal use. Capitalized costs include software packages, installation and/or internal labor costs. These costs generally are amortized over a five-year period.

Property, Plant and Equipment

Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally 3 to 14 years for equipment and furnishings and 10 to 40 years for buildings and improvements. Maintenance and repairs are expensed as incurred.

Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Measurement of an impairment loss for long-lived assets that we expect to hold and use is based on the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

Self-Insurance Reserves

Self-Insurance Reserves Self-Insurance reserves reflect the estimated liability for group health and workers' compensation claims not covered by third-party insurance. We accrue estimated losses based on actuarial models and assumptions as well as our historical loss experience. Workers' compensation accruals are recorded at the estimated ultimate payout amounts based on individual case estimates. In addition, we record estimates of incurred-but-not-reported losses based on actuarial models.

Pension and Nonpension Postretirement Benefits

Pension and Nonpension Postretirement Benefits We account for pension and nonpension postretirement benefits in accordance with FASB ASC Topic 758 - "Compensation-Retirement Plans" ("FASB ASC 758"). FASB ASC 758 requires recognition of the over-funded or under-funded status of pension and other postretirement benefit plans on the balance sheet. Under FASB ASC 758, gains and losses, prior service costs and credits and any remaining prior transaction amounts that have not yet been recognized through net periodic benefit cost are recognized in accumulated other comprehensive loss, net of tax effect where appropriate.

The U.S. pension plans cover most hourly U.S.-based employees (excluding new hires at Shreveport after 2008 and at Toledo after September 30, 2010) and those salaried U.S.-based employees hired before January 1, 2006. U.S. salaried employees are not eligible for additional company contribution credits after December 31, 2012. The non-U.S. pension plans cover the employees of our wholly-owned subsidiaries in the Netherlands and Mexico. For further discussion see note 9.

We also provide certain postretirement health care and life insurance benefits covering substantially all U.S. and Canadian salaried and non-union hourly employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, the existing healthcare benefit for salaried retirees age 65 and older ceased. We now provide a Retiree Health Reimbursement Arrangement (RHRA) that supports salaried retirees in purchasing a Medicare plan that meets their needs. Also effective January 1, 2013, we reduced the maximum life insurance benefit for salaried retirees to $10,000. Employees are generally eligible for benefits upon reaching a certain age and completion of a specified number of years of creditable service. Benefits for most hourly retirees are determined by collective bargaining. Under a cross-indemnity agreement, Owens-Illinois, Inc. assumed liability for the nonpension postretirement benefit of our retirees who had retired as of June 24, 1993. Therefore, the benefits related to these retirees are not included in our liability.

Income Taxes

Income Taxes Income taxes are accounted for under the asset and liability method. Deferred income tax assets and liabilities are recognized for estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax attribute carry-forwards. Deferred income tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. FASB ASC Topic 740, “Income Taxes,” requires that a valuation allowance be recorded when it is more likely than not that some portion or all of the deferred income tax assets will not be realized.

Deferred income tax assets and liabilities are determined separately for each tax jurisdiction in which we conduct our operations or otherwise incur taxable income or losses. In the United States, Portugal and the Netherlands, we have recorded valuation allowances against our deferred income tax assets.

We are subject to income taxes in the U.S. and various foreign jurisdictions. Management judgment is required in evaluating our tax positions and determining our provision for income taxes. Throughout the course of business, there are numerous transactions and calculations for which the ultimate tax determination is uncertain. When management believes certain tax positions may be challenged despite our belief that the tax return positions are supportable, we establish reserves for tax uncertainties based on estimates of whether additional taxes will be due. We adjust these reserves taking into consideration changing facts and circumstances, such as an outcome of a tax audit. The income tax provision includes the impact of reserve provisions and changes to reserves that are considered appropriate. Accruals for tax contingencies are provided for in accordance with the requirements of FASB ASC 740.

In assessing the need for a valuation allowance, management considers whether it is more likely than not that some portion or all of the deferred income tax assets will be realized on a quarterly basis or whenever events indicate that a review is required. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income (including reversals of deferred income tax liabilities) during the periods in which those temporary differences reverse. As a result, we consider the historical and projected financial results of the legal entity or consolidated group recording the net deferred income tax asset as well as all other positive and negative evidence. Examples of the evidence we consider are cumulative losses in recent years, losses expected in early future years, a history of potential tax benefits expiring unused and whether there was an unusual, infrequent, or extraordinary item to be considered.

Derivatives

Derivatives We account for derivatives in accordance with FASB ASC Topic 815 "Derivatives and Hedging" ("FASB ASC 815"). We hold derivative financial instruments to hedge certain of our interest rate risks associated with long-term debt, commodity price risks associated with forecasted future natural gas requirements and foreign exchange rate risks associated with occasional transactions denominated in a currency other than the U.S. dollar. These derivatives (except for the foreign currency contracts) qualify for hedge accounting since the hedges are highly effective, and we have designated and documented contemporaneously the hedging relationships involving these derivative instruments. While we intend to continue to meet the conditions for hedge accounting, if hedges do not qualify as highly effective or if we do not believe that forecasted transactions would occur, the changes in the fair value of the derivatives used as hedges would be reflected in earnings. Cash flows from fair value hedges of debt and short-term forward exchange contracts are classified as an operating activity. Cash flows of currency swaps, interest rate swaps, and commodity futures contracts are classified as operating activities.

Foreign Currency Translation Assets and liabilities of non-U.S. subsidiaries that operate in a local currency environment, where that local currency is the functional currency, are translated to U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive loss. Income and expense accounts are translated at average exchange rates during the year. The effect of exchange rate changes on transactions denominated in currencies other than the functional currency is recorded in other income (expense).

Stock-Based Compensation Expense

Stock-Based Compensation Expense We account for stock-based compensation expense in accordance with FASB ASC Topic 718, “Compensation — Stock Compensation,” ("FASB ASC 718") and FASB ASC Topic 505-50, “Equity-Based Payments to Non-Employees”("FASB ASC 505-50"). Stock-based compensation cost is measured based on the fair value of the equity instruments issued. FASB ASC Topics 718 and 505-50 apply to all of our outstanding unvested stock-based payment awards.

New Accounting Standards

In May 2011, the FASB issued Accounting Standards Update 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). ASU 2011-04 explains how to measure fair value and improves the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and IFRS. ASU 2011-04 does not require additional fair value measurements, and it is not intended to establish valuation standards or affect valuation practices outside of financial reporting. The provisions of this update are effective for periods beginning after December 15, 2011. The provisions of this update did not have any impact on our Consolidated Financial Statements.

In June 2011, the FASB issued Accounting Standards Update 2011-05, “Comprehensive Income (Topic 220): Presentation of Comprehensive Income” (ASU 2011-05). This ASU requires companies to present items of net income, items of other comprehensive income and total comprehensive income in one continuous statement or two separate but consecutive statements. This guidance is effective for fiscal years and interim periods beginning after December 15, 2011 with early adoption permitted. In December 2011, ASU 2011-05 was modified by the issuance of Accounting Standards Update 2011-12, “Comprehensive Income (Topic 220): Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (ASU 2011-12) which defers certain paragraphs of ASU 2011-05 that would require reclassifications of items from other comprehensive income to net income by component of net income and by component of other comprehensive income. We have made all of the required disclosures within our Consolidated Financial Statements.

In July 2012, the FASB issued Accounting Standards Update 2012-02, “Intangibles — Goodwill and Other (Topic 350): Testing Indefinite-Lived Intangible Assets for Impairment” (ASU 2012-02). ASU 2012-02 allows for an option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of the indefinite-lived intangible asset exceeds its carrying amount. If the qualitative factors result in the fair value exceeding the carrying value of the indefinite-lived intangible asset, then the fair value does not need to be calculated. This update is effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, with early adoption permitted. The provisions of this update did not have any impact on our Consolidated Financial Statements.

In February 2013, the FASB issued Accounting Standards Update 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02), which amends Topic 220 Comprehensive Income. ASU 2013-02 requires companies to present, either in a note or parenthetically on the face of the financial statements, the effect of amounts reclassified from each component of accumulated other comprehensive income based on its source and the income statement line items affected by the reclassification. This update is effective for interim and annual reporting periods beginning after December 15, 2012. We will include the additional disclosures in our Consolidated Financial Statements beginning on January 1, 2013.

Indefinite Life Intangible Assets

Indefinite life intangible assets are composed of trade names and trademarks that have an indefinite life and are therefore individually tested for impairment on an annual basis, or more frequently in certain circumstances where impairment indicators arise, in accordance with FASB ASC 350. Our measurement date for impairment testing is October 1st of each year. When performing our test for impairment of individual indefinite life intangible assets, we use a relief from royalty method to determine the fair market value that is compared to the carrying value of the indefinite life intangible asset. The inputs used for this analysis are considered as Level 3 inputs in the fair value hierarchy. See note 15 for further discussion of the fair value hierarchy.

Goodwill

Goodwill impairment tests are completed for each reporting unit on an annual basis, or more frequently in certain circumstances where impairment indicators arise. The inputs used for this analysis are considered as Level 3 inputs in the fair value hierarchy. See note 15 for further discussion of the fair value hierarchy. When performing our test for impairment, we use an approach which includes a discounted cash flow analysis, incorporating the weighted average cost of capital of a hypothetical third party buyer to compute the fair value of each reporting unit. The fair value is then compared to the carrying value. To the extent that fair value exceeds the carrying value, no impairment exists. However, to the extent the carrying value exceeds the fair value, we compare the implied fair value of goodwill to its book value to determine if an impairment should be recorded.

Pensions

The discount rate enables us to estimate the present value of expected future cash flows on the measurement date. The rate used reflects a rate of return on high-quality fixed income investments that match the duration of expected benefit payments at our December 31 measurement date. The discount rate at December 31 is used to measure the year-end benefit obligations and the earnings effects for the subsequent year. A higher discount rate decreases the present value of benefit obligations and decreases pension expense.

To determine the expected long-term rate of return on plan assets for our funded plans, we consider the current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. The expected long-term rate of return on plan assets at December 31^st is used to measure the earnings effects for the subsequent year. The assumed long-term rate of return on assets is applied to a calculated value of plan assets that recognizes gains and losses in the fair value of plan assets compared to expected returns over the next five years. This produces the expected return on plan assets that is included in pension expense. The difference between the expected return and the actual return on plan assets is deferred and amortized over five years. The net deferral of past asset gains (losses) affects the calculated value of plan assets and, ultimately, future pension expense (income).

Future benefits are assumed to increase in a manner consistent with past experience of the plans except for the Libbey U.S. Salaried Pension Plan and SERP as discussed above, which, to the extent benefits are based on compensation, includes assumed compensation increases as presented above. Amortization included in net pension expense is based on the average remaining service of employees.

We account for our defined benefit pension plans on an expense basis that reflects actuarial funding methods. The actuarial valuations require significant estimates and assumptions to be made by management, primarily with respect to the discount rate and expected long-term return on plan assets. These assumptions are all susceptible to changes in market conditions. The discount rate is based on a selected settlement portfolio from a universe of high quality bonds. In determining the expected long-term rate of return on plan assets, we consider historical market and portfolio rates of return, asset allocations and expectations of future rates of return. We evaluate these critical assumptions on our annual measurement date of December 31st. Other assumptions involving demographic factors such as retirement age, mortality and turnover are evaluated periodically and are updated to reflect our experience. Actual results in any given year often will differ from actuarial assumptions because of demographic, economic and other factors.

We have pension plans covering the majority of our employees. Benefits generally are based on compensation and service for salaried employees and job grade and length of service for hourly employees. Our policy is to fund pension plans such that sufficient assets will be available to meet future benefit requirements. In addition, we have an unfunded supplemental employee retirement plan (SERP) that covers salaried U.S.-based employees of Libbey hired before January 1, 2006. The U.S. pension plans cover the salaried U.S.-based employees of Libbey hired before January 1, 2006 and most hourly U.S.-based employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Effective January 1, 2013, we are ceasing annual company contribution credits to the cash balance accounts in our Libbey U.S. Salaried Pension Plan and SERP. The non-U.S. pension plans cover the employees of our wholly owned subsidiaries in the Netherlands and Mexico. The plan in Mexico is not funded.

Nonpension Postretirement Benefits

We provide certain retiree health care and life insurance benefits covering our U.S. and Canadian salaried and non-union hourly employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after 2008 and at Toledo after September 30, 2010). Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. Effective January 1, 2013, we are ending our existing healthcare benefit for salaried retirees age 65 and older and will instead provide a Retiree Health Reimbursement Arrangement (RHRA) that supports retirees in purchasing a Medicare plan that meets their needs. Also effective January 1, 2013, we are reducing the maximum life insurance benefit for salaried retirees to $10,000. Benefits for most hourly retirees are determined by collective bargaining. The U.S. nonpension postretirement plans cover the hourly and salaried U.S.-based employees of Libbey. The non-U.S. nonpension postretirement plans cover the retirees and active employees of Libbey who are located in Canada. The postretirement benefit plans are not funded.

Computation of Income Per Share of Common Stock

Computation of Income Per Share of Common Stock Basic net income per share of common stock is computed using the weighted average number of shares of common stock outstanding during the period. Diluted net income per share of common stock is computed using the weighted average number of shares of common stock outstanding and dilutive potential common share equivalents during the period.

When applicable, diluted shares outstanding include the dilutive impact of warrants and restricted stock units. Diluted shares also include the impact of in-the-money employee stock options, which are calculated based on the average share price for each fiscal period using the treasury stock method. Under the treasury stock method, the tax-effected proceeds that hypothetically would be received from the exercise of all in-the-money options are assumed to be used to repurchase shares.

Fair Value

The fair values of our commodity futures natural gas contracts and currency contracts are determined using observable market inputs. The fair value of our interest rate agreement is based on the market standard methodology of netting the discounted expected future fixed cash receipts and the discounted future variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observed market interest rate forward curves. Since these inputs are observable in active markets over the terms that the instruments are held, the derivatives are classified as Level 2 in the hierarchy. We also evaluate Company and counterparty risk in determining fair values. The commodity futures natural gas contracts, interest rate protection agreements and currency contracts are hedges of either recorded assets or liabilities or anticipated transactions.

Segments

Our measure of profit for our reportable segments is Segment Earnings before Interest and Taxes (Segment EBIT) and excludes amounts related to certain items we consider not representative of ongoing operations as well as certain retained corporate costs. We use Segment EBIT, along with net sales and selected cash flow information, to evaluate performance and to allocate resources. Segment EBIT for reportable segments includes an allocation of some corporate expenses based on both a percentage of sales and direct billings based on the costs of services performed.

Certain activities not related to any particular reportable segment are reported within retained corporate costs. These costs include certain headquarter, administrative and facility costs, and other costs that are global in nature and are not allocable to the reporting segments. Corporate assets primarily include finance fees, capitalized software, and income tax assets.

The accounting policies of the reportable segments are the same as those described in note 2. We do not have any customers who represent 10 percent or more of total sales. We evaluate the performance of our segments based upon sales and Segment Segment EBIT. Inter-segment sales are consummated at arm’s length and are reflected in eliminations below.
