Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies 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. 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. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate governmental agencies. Cost of Sales Cost of sales includes cost to manufacture and/or purchase products, warehouse, shipping and delivery costs and other costs. 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 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. Generally, we do not require collateral on our accounts receivable. 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 29.1 percent and 32.0 percent of our total inventories in 2016 and 2015, 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 $12.9 million and $12.3 million in 2016 and 2015, respectively. Cost includes the cost of materials, direct labor, in-bound freight and the applicable share of manufacturing overhead. 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 1^st of each year, we update our separate impairment evaluations for both goodwill and indefinite life intangible assets. For further disclosure on goodwill and intangibles, see note 4. 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 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. See note 5 for further disclosure. 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 We account for pension and nonpension postretirement benefits in accordance with FASB ASC Topic 715 - "Compensation-Retirement Benefits" ("FASB ASC 715"). FASB ASC 715 requires recognition of the over-funded or under-funded status of pension and other postretirement benefit plans on the balance sheet. Under FASB ASC 715, 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 December 15, 2008 and at Toledo after September 30, 2010) and those salaried U.S.-based employees hired before January 1, 2006. Effective January 1, 2013, we ceased 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 Mexico and the Netherlands (until December 2015). In December 2015, we unwound direct ownership of our defined benefit pension plan in the Netherlands. 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 employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). 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. For further discussion see note 10. 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 paying component in which we conduct our operations or otherwise incur taxable income or losses. For further discussion see note 8. 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 and natural gas hedges in Mexico) 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 hedges of debt, short-term forward exchange contracts, currency swaps, interest rate swaps, and natural gas contracts are classified as operating activities. See additional discussion at note 13. Environmental In accordance with U.S. GAAP accounting standards, we recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated. The cost of the clean-up is estimated by financial and legal specialists based on current law. Such estimates are based primarily upon the estimated cost of investigation and remediation required, and the likelihood that, where applicable, other potentially responsible parties will not be able to fulfill their commitments at the sites where the Company may be jointly and severally liable. 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. For further detail see note 17. 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 718 and 505-50 apply to all of our outstanding unvested stock-based payment awards. Treasury Stock Treasury Stock purchases are recorded at cost. During 2016, 2015 and 2014, we purchased 111,292, 412,473 and 34,985 shares of treasury stock at an average price of $17.97, $37.03 and $30.30, respectively. At December 31, 2016, we had 941,250 shares of common stock available for repurchase, as authorized by our Board of Directors. Research and Development Research and development costs are charged to selling, general and administrative expense in the Consolidated Statements of Operations when incurred. Expenses for 2016, 2015 and 2014, respectively, were $4.3 million, $6.1 million and $6.2 million. Advertising Costs We expense all advertising costs as incurred. The expenses for 2016, 2015 and 2014, respectively, were $5.7 million, $10.7 million and $4.1 million. 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. Reclassifications Certain amounts in prior years' financial statements have been reclassified to conform to the presentation used in the year ended December 31, 2016, including the reclassification of pension assets in the fair value hierarchy table in accordance with adopting ASU 2015-07 at December 31, 2016. See below and note 9. New Accounting Standards In May 2014, the FASB issued Accounting Standards Update No. 2014-09, "Revenue From Contracts With Customers", as amended by ASU's 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20, (ASU 2014-09), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. This update is effective for interim and annual reporting periods beginning after December 15, 2017. We plan to adopt this standard in the first quarter of 2018 using the modified retrospective method, whereby the cumulative effect of applying the standard is recognized at the date of initial application. We have substantially completed our evaluation of significant contracts and the review of our current accounting policies and practices to identify potential differences that would result from applying the requirements of ASU 2014-09 to our revenue contracts. In addition, we have identified, and are in the process of implementing, appropriate changes to business processes, systems and controls to support recognition and disclosure under the new standard. We do not expect the adoption of ASU 2014-09 to have a material impact on the amount and timing of revenue recognized in our Consolidated Financial Statements. In August 2014, the FASB issued Accounting Standards Update No. 2014-15, "Presentation of Financial Statements-Going Concern" (ASU 2014-15), which establishes management’s responsibility, in connection with preparing financial statements for each annual and interim reporting period, to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 also provides guidance to determine whether to disclose information about relevant conditions and events when there is substantial doubt about an entity’s ability to continue as a going concern. This update is effective for the annual reporting period ending after December 15, 2016, and for interim and annual periods thereafter. Early application was permitted. We adopted ASU 2014-15 as of December 31, 2016, and it had no impact on our balance sheet, results of operations, cash flows or disclosures at December 31, 2016. In May 2015, the FASB issued Accounting Standards Update 2015-07, "Disclosures for Investments in Certain Entities that Calculate Net Asset Value Per Share (or its Equivalent)" (ASU 2015-07), which removes the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value (NAV) practical expedient provided by FASB ASC Topic 820, Fair Value Measurement. Disclosures about investments in certain entities that calculate NAV per share are limited under ASU 2015-07 to those investments for which the entity has elected to estimate the fair value using the NAV practical expedient. ASU 2015-07 is effective for entities for fiscal years beginning after December 15, 2015 and interim periods within, with retrospective application to all periods presented. Early application was permitted. We adopted ASU 2015-07 as of January 1, 2016. The guidance impacted the presentation of our pension assets that use NAV as a practical expedient (see note 9, Pension). In February 2016, the FASB issued Accounting Standards Update No. 2016-02, "Leases (Topic 842)" (ASU 2016-02), which requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months on the balance sheet. Leases will be classified as either finance or operating leases, with classification affecting the pattern of expense recognition in the income statement. The new guidance also clarifies the definition of a lease and disclosure requirements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early application permitted. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach does not require any transition accounting for leases that expired before the earliest comparative period presented. We are currently evaluating the impact of this standard and anticipate the new guidance will significantly impact our Consolidated Financial Statements as we have a significant number of leases. See note 16, Operating Leases, for our minimum lease commitments under non-cancellable operating leases. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09). Areas for simplification in this update involve several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016, with early application permitted. When we adopt this in the first quarter of 2017, there will be an adjustment to retained earnings as of January 1, 2017, an immaterial impact to the Consolidated Statements of Operations, and a reclass between operating and financing activities on the previously reported Consolidated Statements of Cash Flows that will increase cash provided by operating activities and decrease cash used in financing activities. In June 2016, the FASB issued Accounting Standards Update No. 2016-13. "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" (ASU 2016-13). This standard introduces a new approach to estimating credit losses on certain types of financial instruments, including trade receivables, and modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim period within those fiscal years, with early application permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements. In August 2016, the FASB issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" (ASU 2016-15). ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the Statement of Cash Flows. ASU 2016-15 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements. In October 2016, the FASB issued Accounting Standards Update No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory" (ASU 2016-16). ASU 2016-16 clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements. In January 2017, the FASB issued Accounting Standards Update No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" (ASU 2017-04). ASU 2017-04 simplifies the goodwill impairment testing by eliminating Step 2 from the goodwill impairment testing required, should an impairment be discovered during its annual or interim assessment. ASU 2017-04 is effective for annual or interim impairment tests beginning after December 15, 2019, with early adoption permitted. We plan to adopt this standard for our annual, and any interim, goodwill impairment testing to be performed after January 1, 2017.

Significant Accounting Policies

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.

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. Taxes collected from customers are excluded from revenues and credited directly to obligations to the appropriate governmental agencies.

Cost of Sales Cost of sales includes cost to manufacture and/or purchase products, warehouse, shipping and delivery costs and other costs.

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 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. Generally, we do not require collateral on our accounts receivable.

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 29.1 percent and 32.0 percent of our total inventories in 2016 and 2015, 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 $12.9 million and $12.3 million in 2016 and 2015, respectively. Cost includes the cost of materials, direct labor, in-bound freight and the applicable share of manufacturing overhead.

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 1^st of each year, we update our separate impairment evaluations for both goodwill and indefinite life intangible assets. For further disclosure on goodwill and intangibles, see note 4.

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 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. See note 5 for further disclosure.

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 We account for pension and nonpension postretirement benefits in accordance with FASB ASC Topic 715 - "Compensation-Retirement Benefits" ("FASB ASC 715"). FASB ASC 715 requires recognition of the over-funded or under-funded status of pension and other postretirement benefit plans on the balance sheet. Under FASB ASC 715, 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 December 15, 2008 and at Toledo after September 30, 2010) and those salaried U.S.-based employees hired before January 1, 2006. Effective January 1, 2013, we ceased 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 Mexico and the Netherlands (until December 2015). In December 2015, we unwound direct ownership of our defined benefit pension plan in the Netherlands. 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 employees hired before January 1, 2004 and a majority of our union hourly employees (excluding employees hired at Shreveport after December 15, 2008 and at Toledo after September 30, 2010). 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. For further discussion see note 10.

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 paying component in which we conduct our operations or otherwise incur taxable income or losses. For further discussion see note 8.

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 and natural gas hedges in Mexico) 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 hedges of debt, short-term forward exchange contracts, currency swaps, interest rate swaps, and natural gas contracts are classified as operating activities. See additional discussion at note 13.

Environmental In accordance with U.S. GAAP accounting standards, we recognize environmental clean-up liabilities on an undiscounted basis when loss is probable and can be reasonably estimated. The cost of the clean-up is estimated by financial and legal specialists based on current law. Such estimates are based primarily upon the estimated cost of investigation and remediation required, and the likelihood that, where applicable, other potentially responsible parties will not be able to fulfill their commitments at the sites where the Company may be jointly and severally liable.

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. For further detail see note 17.

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 718 and 505-50 apply to all of our outstanding unvested stock-based payment awards.

Treasury Stock Treasury Stock purchases are recorded at cost. During 2016, 2015 and 2014, we purchased 111,292, 412,473 and 34,985 shares of treasury stock at an average price of $17.97, $37.03 and $30.30, respectively. At December 31, 2016, we had 941,250 shares of common stock available for repurchase, as authorized by our Board of Directors.

Research and Development Research and development costs are charged to selling, general and administrative expense in the Consolidated Statements of Operations when incurred. Expenses for 2016, 2015 and 2014, respectively, were $4.3 million, $6.1 million and $6.2 million.

Advertising Costs We expense all advertising costs as incurred. The expenses for 2016, 2015 and 2014, respectively, were $5.7 million, $10.7 million and $4.1 million.

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.

Reclassifications Certain amounts in prior years' financial statements have been reclassified to conform to the presentation used in the year ended December 31, 2016, including the reclassification of pension assets in the fair value hierarchy table in accordance with adopting ASU 2015-07 at December 31, 2016. See below and note 9.

New Accounting Standards

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, "Revenue From Contracts With Customers", as amended by ASU's 2015-14, 2016-08, 2016-10, 2016-11, 2016-12 and 2016-20, (ASU 2014-09), which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. Entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. This update is effective for interim and annual reporting periods beginning after December 15, 2017. We plan to adopt this standard in the first quarter of 2018 using the modified retrospective method, whereby the cumulative effect of applying the standard is recognized at the date of initial application. We have substantially completed our evaluation of significant contracts and the review of our current accounting policies and practices to identify potential differences that would result from applying the requirements of ASU 2014-09 to our revenue contracts. In addition, we have identified, and are in the process of implementing, appropriate changes to business processes, systems and controls to support recognition and disclosure under the new standard. We do not expect the adoption of ASU 2014-09 to have a material impact on the amount and timing of revenue recognized in our Consolidated Financial Statements.

In August 2014, the FASB issued Accounting Standards Update No. 2014-15, "Presentation of Financial Statements-Going Concern" (ASU 2014-15), which establishes management’s responsibility, in connection with preparing financial statements for each annual and interim reporting period, to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 also provides guidance to determine whether to disclose information about relevant conditions and events when there is substantial doubt about an entity’s ability to continue as a going concern. This update is effective for the annual reporting period ending after December 15, 2016, and for interim and annual periods thereafter. Early application was permitted. We adopted ASU 2014-15 as of December 31, 2016, and it had no impact on our balance sheet, results of operations, cash flows or disclosures at December 31, 2016.

In May 2015, the FASB issued Accounting Standards Update 2015-07, "Disclosures for Investments in Certain Entities that Calculate Net Asset Value Per Share (or its Equivalent)" (ASU 2015-07), which removes the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value (NAV) practical expedient provided by FASB ASC Topic 820, Fair Value Measurement. Disclosures about investments in certain entities that calculate NAV per share are limited under ASU 2015-07 to those investments for which the entity has elected to estimate the fair value using the NAV practical expedient. ASU 2015-07 is effective for entities for fiscal years beginning after December 15, 2015 and interim periods within, with retrospective application to all periods presented. Early application was permitted. We adopted ASU 2015-07 as of January 1, 2016. The guidance impacted the presentation of our pension assets that use NAV as a practical expedient (see note 9, Pension).

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, "Leases (Topic 842)" (ASU 2016-02), which requires a lessee to recognize assets and liabilities for leases with lease terms of more than 12 months on the balance sheet. Leases will be classified as either finance or operating leases, with classification affecting the pattern of expense recognition in the income statement. The new guidance also clarifies the definition of a lease and disclosure requirements. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early application permitted. Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach does not require any transition accounting for leases that expired before the earliest comparative period presented. We are currently evaluating the impact of this standard and anticipate the new guidance will significantly impact our Consolidated Financial Statements as we have a significant number of leases. See note 16, Operating Leases, for our minimum lease commitments under non-cancellable operating leases.

In March 2016, the FASB issued Accounting Standards Update No. 2016-09, "Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09). Areas for simplification in this update involve several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016, with early application permitted. When we adopt this in the first quarter of 2017, there will be an adjustment to retained earnings as of January 1, 2017, an immaterial impact to the Consolidated Statements of Operations, and a reclass between operating and financing activities on the previously reported Consolidated Statements of Cash Flows that will increase cash provided by operating activities and decrease cash used in financing activities.

In June 2016, the FASB issued Accounting Standards Update No. 2016-13. "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments" (ASU 2016-13). This standard introduces a new approach to estimating credit losses on certain types of financial instruments, including trade receivables, and modifies the impairment model for available-for-sale debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, including interim period within those fiscal years, with early application permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments" (ASU 2016-15). ASU 2016-15 addresses how certain cash receipts and cash payments are presented and classified in the Statement of Cash Flows. ASU 2016-15 is effective for interim and annual periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements.

In October 2016, the FASB issued Accounting Standards Update No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory" (ASU 2016-16). ASU 2016-16 clarifies that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. ASU 2016-16 is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. We are currently assessing the impact that this standard will have on our Consolidated Financial Statements.

In January 2017, the FASB issued Accounting Standards Update No. 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" (ASU 2017-04). ASU 2017-04 simplifies the goodwill impairment testing by eliminating Step 2 from the goodwill impairment testing required, should an impairment be discovered during its annual or interim assessment. ASU 2017-04 is effective for annual or interim impairment tests beginning after December 15, 2019, with early adoption permitted. We plan to adopt this standard for our annual, and any interim, goodwill impairment testing to be performed after January 1, 2017.
