Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Lear Corporation ("Lear," and together with its consolidated subsidiaries, the "Company") and its affiliates design and manufacture automotive seating and electrical distribution systems and related components. The Company’s main customers are automotive original equipment manufacturers. The Company operates facilities worldwide. The accompanying condensed consolidated financial statements include the accounts of Lear, a Delaware corporation, and the wholly owned and less than wholly owned subsidiaries controlled by Lear. In addition, Lear consolidates all entities, including variable interest entities, in which it has a controlling financial interest. Investments in affiliates in which Lear does not have control, but does have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method. In the second quarter of 2019, the Company completed the acquisition of Xevo Inc. (“Xevo”), a Seattle-based, global leader in connected car software, by acquiring all of Xevo's outstanding shares. The acquisition of Xevo has been accounted for as a business combination, and accordingly, the assets acquired and liabilities assumed are included in the accompanying condensed consolidated balance sheets as of April 4, 2020 and December 31, 2019. The operating results and cash flows of Xevo are included in the accompanying condensed consolidated financial statements from the date of acquisition and in the Company's E-Systems segment. For further information related to the acquisition of Xevo, see Note 3, “Acquisition,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 . The Company’s annual financial results are reported on a calendar year basis, and quarterly interim results are reported using a thirteen week reporting calendar.

Impact of COVID-19 Pandemic

Impact of COVID-19 Pandemic	3 Months Ended

Unusual or Infrequent Items, or Both [Abstract]
Impact of COVID-19 Pandemic	Impact of COVID-19 Pandemic Unprecedented industry disruptions related to the COVID-19 pandemic during the first quarter of 2020 impacted operations in every region of the world. Our operations in China were impacted first, with most plants in the country closed for several weeks during the quarter. At the end of the quarter, all of our facilities in China were operating and capacity utilization is increasing. Beginning in mid-March, our operations in Europe, North America, South America and Asia (excluding China) were impacted, with virtually all plants closed at the end of the quarter and closures continuing throughout April and, in most cases, into May. While manufacturing has resumed at certain locations in Europe and North America, production levels at these facilities are currently well below capacity. Accordingly, the COVID-19 pandemic is expected to have a material impact on the Company's second quarter 2020 sales, operating results and cash flows. It is also likely that the global automotive industry will experience lower demand for new vehicle sales for a period of time as a result of the global economic slowdown caused by the COVID-19 pandemic, as new vehicle sales are correlated with positive consumer confidence and low unemployment. In addition, the Company's customers may request extended payment terms, as part of their own response to the COVID-19 pandemic. Finally, a resurgence of the virus with corresponding shelter-in-place orders later in the year could further impact the Company's financial results. The accompanying condensed consolidated financial statements reflect estimates and assumptions made by management as of April 4, 2020, and for the three months then ended. Such estimates and assumptions affect, among other things, the Company's goodwill, long-lived asset and indefinite-lived intangible asset valuations; inventory valuations; assessment of the annual effective tax rate; valuation of deferred income taxes and income tax contingencies; and credit losses related to our financial instruments. Events and circumstances arising after April 4, 2020, including those resulting from the impact of the COVID-19 pandemic, will be reflected in management's estimates and assumptions in future periods. For information related to goodwill, see Note 7 , " Goodwill ," herein and Note 2, "Summary of Significant Accounting Policies — Impairment of Goodwill and Intangible Assets," to the consolidated financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019.

Restructuring

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring Restructuring costs include employee termination benefits, asset impairment charges and contract termination costs, as well as other incremental costs resulting from the restructuring actions. Employee termination benefits are recorded based on existing union and employee contracts, statutory requirements, completed negotiations and Company policy. Other incremental costs principally include equipment and personnel relocation costs. In addition to restructuring costs, the Company incurs incremental manufacturing inefficiency costs at the operating locations impacted by the restructuring actions during the related restructuring implementation period. Restructuring costs are recognized in the Company’s condensed consolidated financial statements in accordance with GAAP. Generally, charges are recorded as restructuring actions are approved and/or implemented. In the first three months of 2020 , the Company recorded charges of $32.6 million in connection with its restructuring actions. These charges consist of $28.2 million recorded as cost of sales and $4.4 million recorded as selling, general and administrative expenses. The restructuring charges consist of employee termination costs of $20.0 million , asset impairment charges of $10.4 million and contract termination costs of $0.2 million , as well as other related costs of $2.0 million . Employee termination benefits were recorded based on existing union and employee contracts, statutory requirements, completed negotiations and Company policy. Asset impairment charges relate to the disposal of buildings, leasehold improvements and/or machinery and equipment with carrying values of $10.4 million in excess of related estimated fair values. The Company expects to incur approximately $46 million of additional restructuring costs related to activities initiated as of April 4, 2020 , and expects that the components of such costs will be consistent with its historical experience. Any future restructuring actions will depend upon market conditions, customer actions and other factors. A summary of 2020 activity is shown below (in millions): Accrual as of 2020 Utilization Accrual as of January 1, 2020 Charges Cash Non-cash April 4, 2020 Employee termination benefits $ 152.8 $ 20.0 $ (44.5 ) $ — $ 128.3 Asset impairment charges — 10.4 — (10.4 ) — Contract termination costs 4.9 0.2 (0.2 ) — 4.9 Other related costs — 2.0 (2.0 ) — — Total $ 157.7 $ 32.6 $ (46.7 ) $ (10.4 ) $ 133.2

Pre-Production Costs Related to Long-Term Supply Agreements	Pre-Production Costs Related to Long-Term Supply Agreements The Company incurs pre-production engineering and development ("E&D") and tooling costs related to the products produced for its customers under long-term supply agreements. The Company expenses all pre-production E&D costs for which reimbursement is not contractually guaranteed by the customer. In addition, the Company expenses all pre-production tooling costs related to customer-owned tools for which reimbursement is not contractually guaranteed by the customer or for which the Company does not have a non-cancelable right to use the tooling. During the first three months of 2020 and 2019 , the Company capitalized $50.4 million and $58.8 million , respectively, of pre-production E&D costs for which reimbursement is contractually guaranteed by the customer. During the first three months of 2020 and 2019 , the Company also capitalized $54.1 million and $47.0 million , respectively, of pre-production tooling costs related to customer-owned tools for which reimbursement is contractually guaranteed by the customer or for which the Company has a non-cancelable right to use the tooling. These amounts are included in other current and long-term assets in the accompanying condensed consolidated balance sheets. During the first three months of 2020 and 2019 , the Company collected $66.8 million and $95.8 million , respectively, of cash related to E&D and tooling costs.

Property, Plant and Equipment [Abstract]
Long-Term Assets	Long-Term Assets Property, plant and equipment is stated at cost. Costs associated with the repair and maintenance of the Company’s property, plant and equipment are expensed as incurred. Costs associated with improvements which extend the life, increase the capacity or improve the efficiency or safety of the Company’s property, plant and equipment are capitalized and depreciated over the remaining useful life of the related asset. Depreciable property is depreciated over the estimated useful lives of the assets, using principally the straight-line method. A summary of property, plant and equipment is shown below (in millions): April 4, December 31, Land $ 107.4 $ 113.1 Buildings and improvements 801.3 831.3 Machinery and equipment 3,812.7 3,844.1 Construction in progress 362.2 382.4 Total property, plant and equipment 5,083.6 5,170.9 Less – accumulated depreciation (2,475.2 ) (2,466.7 ) Property, plant and equipment, net $ 2,608.4 $ 2,704.2 Depreciation expense was $113.4 million and $110.9 million in the three months ended April 4, 2020 and March 30, 2019 , respectively. The Company monitors its long-lived assets for impairment indicators on an ongoing basis in accordance with GAAP. If impairment indicators exist, the Company performs the required impairment analysis by comparing the undiscounted cash flows expected to be generated from the long-lived assets to the related net book values. If the net book value exceeds the undiscounted cash flows, an impairment loss is measured and recognized. In the first quarter of 2020, the Company did not recognize any long-lived asset impairment charges, except in conjunction with its restructuring actions as discussed below. The Company will, however, continue to assess the impact of any significant industry events on the realization of its long-lived assets. In the first three months of 2020 and 2019 , the Company recognized asset impairment charges of $10.4 million and $2.1 million , respectively, in conjunction with its restructuring actions (Note 3 , " Restructuring ").

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Goodwill A summary of the changes in the carrying amount of goodwill, by operating segment, in the three months ended April 4, 2020 , is shown below (in millions): Seating E-Systems Total Balance at January 1, 2020 $ 1,235.4 $ 378.9 $ 1,614.3 Foreign currency translation and other (20.0 ) (2.1 ) (22.1 ) Balance at April 4, 2020 $ 1,215.4 $ 376.8 $ 1,592.2 Goodwill is not amortized but is tested for impairment on at least an annual basis. Impairment testing is required more often than annually if an event or circumstance indicates that an impairment is more likely than not to have occurred. In conducting its annual impairment testing, the Company may first perform a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, or if the Company elects not to perform a qualitative assessment of a reporting unit, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill recorded. The Company conducts its annual impairment testing as of the first day of its fourth quarte r. During the first quarter of 2020 , an interim goodwill impairment analysis related to one of the Company’s reporting units within its E-Systems operating segment was performed, largely due to industry disruptions resulting from the COVID-19 pandemic. As of April 4, 2020 , the results of the quantitative analysis indicated that the fair value of the reporting unit exceeded the related carrying value. The goodwill impairment analysis reflected the Company’s best estimates of the COVID-19 pandemic’s ultimate impact on industry conditions, including consumer demand, as well as economic recovery. The reporting unit is at risk of failing a future quantitative assessment if the impact of the COVID-19 pandemic is more severe or if economic recovery is slower or weaker than anticipated. As of April 4, 2020 , the goodwill of the reporting unit represents less than 10% of the Company’s total goodwill.

Revenue Recognition

Revenue Recognition	3 Months Ended
	Apr. 04, 2020
Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition The Company enters into contracts with its customers to provide production parts generally at the beginning of a vehicle’s life cycle. Typically, these contracts do not provide for a specified quantity of products, but once entered into, the Company is often expected to fulfill its customers’ purchasing requirements for the production life of the vehicle. Many of these contracts may be terminated by the Company’s customers at any time. Historically, terminations of these contracts have been minimal. The Company receives purchase orders from its customers, which provide the commercial terms for a particular production part, including price (but not quantities). Contracts may also provide for annual price reductions over the production life of the vehicle, and prices may be adjusted on an ongoing basis to reflect changes in product content/cost and other commercial factors. Revenue is recognized at a point in time when control of the product is transferred to the customer under standard commercial terms, as the Company does not have an enforceable right to payment prior to such transfer. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to in exchange for those products based on the annual purchase orders, annual price reductions and ongoing price adjustments. The Company's customers pay for products received in accordance with payment terms that are customary within the industry. The Company's contracts with its customers do not have significant financing components. The Company records a contract liability for advances received from its customers. As of April 4, 2020 and December 31, 2019 , there were no significant contract liabilities recorded. Further, there were no significant contract liabilities recognized in revenue during the first three months of 2020 . Amounts billed to customers related to shipping and handling costs are included in net sales in the condensed consolidated statements of comprehensive income (loss). Shipping and handling costs are accounted for as fulfillment costs and are included in cost of sales in the condensed consolidated statements of comprehensive income (loss). Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that are collected by the Company from a customer are excluded from revenue.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes A summary of the provision for income taxes and the corresponding effective tax rate for the three months ended April 4, 2020 and March 30, 2019 , is shown below (in millions, except effective tax rates): Three Months Ended April 4, March 30, Provision for income taxes $ 26.5 $ 43.1 Pretax income before equity in net income of affiliates $ 108.5 $ 286.9 Effective tax rate 24.4 % 15.0 % In the first three months of 2020 and 2019 , the provision for income taxes was primarily impacted by the level and mix of earnings among tax jurisdictions. In addition, the Company recognized tax benefits (expense) related to the significant, discrete items shown below (in millions): Three Months Ended April 4, March 30, 2019 Restructuring charges and various other items $ 10.0 $ 15.6 Valuation allowances on deferred tax assets of a foreign subsidiary 0.8 — Share-based compensation (0.2 ) 3.2 Change in tax status of certain affiliates — 18.4 $ 10.6 $ 37.2 Excluding the items above, the effective tax rate for the first three months of 2020 and 2019 approximated the U.S. federal statutory income tax rate of 21% , adjusted for income taxes on foreign earnings, losses and remittances, valuation allowances, tax credits, income tax incentives and other permanent items. For the three months ended April 4, 2020 , the Company utilized the discrete effective tax rate method, as allowed by Accounting Standards Codification 740, “Income Taxes,” to calculate its interim income tax provision. The discrete method is applied when the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate. The discrete method treats the year-to-date period as if it was the annual period and determines the income tax expense or benefit on that basis. The Company believes that, as a result of the current uncertainty due to the COVID-19 pandemic, the application of the estimated annual effective tax rate is impractical because it is not possible to reliably estimate the annual effective tax rate as minor changes in annual forecasted pre-tax income or income tax expense or benefit can produce significant changes in the estimated annual effective tax rate. For the three months ended March 30, 2019, the Company calculated its interim income tax provision based on the estimated annual effective rate. The Company’s current and future provision for income taxes is impacted by the initial recognition of and changes in valuation allowances in certain countries. The Company intends to maintain these allowances until it is more likely than not that the deferred tax assets will be realized. The Company’s future provision for income taxes will include no tax benefit with respect to losses incurred and, except for certain jurisdictions, no tax expense with respect to income generated in these countries until the respective valuation allowances are eliminated. Accordingly, income taxes are impacted by changes in valuation allowances and the mix of earnings among jurisdictions. The Company evaluates the realizability of its deferred tax assets on a quarterly basis. In completing this evaluation, the Company considers all available evidence in order to determine whether, based on the weight of the evidence, a valuation allowance for its deferred tax assets is necessary. Such evidence includes historical results, future reversals of existing taxable temporary differences and expectations for future taxable income (exclusive of the reversal of temporary differences and carryforwards), as well as the implementation of feasible and prudent tax planning strategies. If, based on the weight of the evidence, it is more likely than not that all or a portion of the Company’s deferred tax assets will not be realized, a valuation allowance is recorded. If operating results improve or decline on a continual basis in a particular jurisdiction, the Company’s decision regarding the need for a valuation allowance could change, resulting in either the initial recognition or reversal of a valuation allowance in that jurisdiction, which could have a significant impact on income tax expense in the period recognized and subsequent periods. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments, which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities. For further information related to the Company's income taxes, see Note 8, "Income Taxes," to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019

Earnings Per Share [Abstract]
Net Income Per Share Attributable to Lear	Net Income Per Share Attributable to Lear Basic net income per share available to Lear common stockholders is computed using the two-class method by dividing net income attributable to Lear, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Common shares issuable upon the satisfaction of certain conditions pursuant to a contractual agreement are considered common shares outstanding and are included in the computation of basic net income per share available to Lear common stockholders. Diluted net income per share available to Lear common stockholders is computed using the two-class method by dividing net income attributable to Lear, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding, including the dilutive effect of common stock equivalents computed using the treasury stock method and the average share price during the period.

Lear Corporation Stockholders’ Equity Common Stock Share Repurchase Program In March 2020, as a proactive measure in response to the COVID-19 pandemic, the Company temporarily suspended share repurchases under its share repurchase program. Shares repurchases in the first quarter of 2020 (prior to the suspension) are shown below (in millions except for shares and per share amounts): Three Months Ended As of April 4, 2020 April 4, 2020 Aggregate Repurchases Cash paid for Repurchases Number of Shares Average Price per Share (1) Remaining Purchase Authorization $ 70.0 $ 70.0 641,149 $ 109.22 $ 1,430.0 (1) Excludes commissions Since the first quarter of 2011, the Company's Board of Directors has authorized $6.1 billion in share repurchases under the common stock share repurchase program. As of the end of the first quarter of 2020 , the Company has repurchased, in aggregate, $4.7 billion of its outstanding common stock, at an average price of $90.07 per share, excluding commissions and related fees. The Company may implement share repurchases through a variety of methods, including, but not limited to, open market purchases, accelerated stock repurchase programs and structured repurchase transactions. The extent to which the Company will repurchase its outstanding common stock and the timing of such repurchases will depend upon its financial condition, prevailing market conditions, alternative uses of capital and other factors. In addition to shares repurchased under the Company’s common stock share repurchase program described above, the Company classified shares withheld from the settlement of the Company’s restricted stock unit and performance share awards to cover tax withholding requirements as common stock held in treasury in the accompanying condensed consolidated balance sheets as of April 4, 2020 and December 31, 2019 .

Commitments and Contingencies Disclosure [Abstract]
Legal and Other Contingencies	Legal and Other Contingencies As of April 4, 2020 and December 31, 2019 , the Company had recorded reserves for pending legal disputes, including commercial disputes and other matters, of $14.1 million and $14.0 million , respectively. Such reserves reflect amounts recognized in accordance with GAAP and typically exclude the cost of legal representation. Product liability and warranty reserves are recorded separately from legal reserves, as described below. Commercial Disputes The Company is involved from time to time in legal proceedings and claims, including, without limitation, commercial or contractual disputes with its customers, suppliers and competitors. These disputes vary in nature and are usually resolved by negotiations between the parties. Product Liability and Warranty Matters In the event that use of the Company’s products results in, or is alleged to result in, bodily injury and/or property damage or other losses, the Company may be subject to product liability lawsuits and other claims. Such lawsuits generally seek compensatory damages, punitive damages and attorneys’ fees and costs. In addition, if any of the Company’s products are, or are alleged to be, defective, the Company may be required or requested by its customers to participate in a recall or other corrective action involving such products. Certain of the Company’s customers have asserted claims against the Company for costs related to recalls or other corrective actions involving its products. The Company can provide no assurances that it will not experience material claims in the future or that it will not incur significant costs to defend such claims. To a lesser extent, the Company is a party to agreements with certain of its customers, whereby these customers may pursue claims against the Company for contribution of all or a portion of the amounts sought in connection with product liability and warranty claims. In certain instances, allegedly defective products may be supplied by Tier 2 suppliers. The Company may seek recovery from its suppliers of materials or services included within the Company’s products that are associated with product liability and warranty claims. The Company carries insurance for certain legal matters, including product liability claims, but such coverage may be limited. The Company does not maintain insurance for product warranty or recall matters. Future dispositions with respect to the Company’s product liability claims that were subject to compromise under the Chapter 11 bankruptcy proceedings will be satisfied out of a common stock and warrant reserve established for that purpose. The Company records product warranty reserves when liability is probable and related amounts are reasonably estimable. A summary of the changes in reserves for product liability and warranty claims for the three months ended April 4, 2020 , is shown below (in millions): Balance at January 1, 2020 $ 32.0 Expense, net (including changes in estimates) 5.4 Settlements (2.9 ) Foreign currency translation and other (0.7 ) Balance at April 4, 2020 $ 33.8 Environmental Matters The Company is subject to local, state, federal and foreign laws, regulations and ordinances which govern activities or operations that may have adverse environmental effects and which impose liability for clean-up costs resulting from past spills, disposals or other releases of hazardous wastes and environmental compliance. The Company’s policy is to comply with all applicable environmental laws and to maintain an environmental management program based on ISO 14001 to ensure compliance with this standard. However, the Company currently is, has been and in the future may become the subject of formal or informal enforcement actions or procedures. As of April 4, 2020 and December 31, 2019 , the Company had recorded environmental reserves of $9.2 million and $9.3 million , respectively. The Company does not believe that the environmental liabilities associated with its current and former properties will have a material adverse impact on its business, financial condition, results of operations or cash flows; however, no assurances can be given in this regard. Other Matters The Company is involved from time to time in various other legal proceedings and claims, including, without limitation, intellectual property matters, tax claims and employment matters. Although the outcome of any legal matter cannot be predicted with certainty, the Company does not believe that any of the other legal proceedings or claims in which the Company is currently involved, either individually or in the aggregate, will have a material adverse impact on its business, financial condition, results of operations or cash flows. However, no assurances can be given in this regard. Although the Company records reserves for legal disputes, product liability and warranty claims and environmental and other matters in accordance with GAAP, the ultimate outcomes of these matters are inherently uncertain. Actual results may differ significantly from current estimates.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company has two reportable operating segments: Seating, which includes complete seat systems and all major seat components, including seat covers and surface materials such as leather and fabric, seat structures and mechanisms, seat foam and headrests, and E-Systems, which includes complete electrical distribution systems, as well as sophisticated electronic control modules, electrification products and connectivity products. Key components in the Company's electrical distribution portfolio include wire harnesses, terminals and connectors and junction boxes for both internal combustion engine and electrification architectures that require management of higher voltage and power. Key components in the Company's electronic control module portfolio include body control modules, wireless receiver and transmitter technology and lighting and audio control modules, as well as products specific to electrification and connectivity trends. Electrification products include charging systems (onboard charging modules and cord set charging equipment), battery electronics (battery disconnect units, cell monitoring supervisory systems and integrated total battery control modules) and other power management modules, including converter and inverter systems. Connectivity products include gateway modules and communication modules to manage both wired and wireless networks and data in vehicles. The other category includes unallocated costs related to corporate headquarters, regional headquarters and the elimination of intercompany activities, none of which meets the requirements for being classified as an operating segment. Corporate and regional headquarters costs include various support functions, such as information technology, advance research and development, corporate finance, legal, executive administration and human resources, as well as advanced engineering expenses. Each of the Company’s operating segments reports its results from operations and makes its requests for capital expenditures directly to the chief operating decision maker. The economic performance of each operating segment is driven primarily by automotive production volumes in the geographic regions in which it operates, as well as by the success of the vehicle platforms for which it supplies products. Also, each operating segment operates in the competitive Tier 1 automotive supplier environment and is continually working with its customers to manage costs and improve quality. The Company’s production processes generally make use of hourly labor, dedicated facilities, sequential manufacturing and assembly processes and commodity raw materials. The Company evaluates the performance of its operating segments based primarily on (i) revenues from external customers, (ii) pretax income before equity in net income of affiliates, interest expense and other expense ("segment earnings") and (iii) cash flows, being defined as segment earnings less capital expenditures plus depreciation and amortization. A summary of revenues from external customers and other financial information by reportable operating segment is shown below (in millions): Three Months Ended April 4, 2020 Seating E-Systems Other Consolidated Revenues from external customers $ 3,366.6 $ 1,091.1 $ — $ 4,457.7 Segment earnings (1) 186.1 32.4 (45.1 ) 173.4 Depreciation and amortization 83.5 43.1 3.9 130.5 Capital expenditures 66.2 41.7 1.2 109.1 Total assets 6,861.8 2,920.3 3,240.2 13,022.3 Three Months Ended March 30, 2019 Seating E-Systems Other Consolidated Revenues from external customers $ 3,913.7 $ 1,246.4 $ — $ 5,160.1 Segment earnings (1) 252.3 128.3 (68.4 ) 312.2 Depreciation and amortization 82.9 36.8 3.9 123.6 Capital expenditures 80.2 39.1 3.5 122.8 Total assets 7,702.2 2,703.2 1,956.6 12,362.0 (1) See definition above For the three months ended April 4, 2020 , segment earnings include restructuring charges of $12.3 million and $20.3 million in the Seating and E-Systems segments, respectively. The Company expects to incur approximately $19 million and approximately $27 million of additional restructuring costs in the Seating and E-Systems segments, respectively, related to activities initiated as of April 4, 2020 , and expects that the components of such costs will be consistent with its historical experience. For the three months ended March 30, 2019 , segment earnings include restructuring charges of $45.2 million , $8.9 million and $0.2 million in the Seating and E-Systems segments and in the other category, respectively. For further information, see Note 3 , " Restructuring ." A reconciliation of segment earnings to consolidated income before provision for income taxes and equity in net income of affiliates is shown below (in millions): Three Months Ended April 4, March 30, Segment earnings $ 173.4 $ 312.2 Interest expense 24.4 20.9 Other expense, net 40.5 4.4 Consolidated income before provision for income taxes and equity in net income of affiliates $ 108.5 $ 286.9

Fair Value Disclosures [Abstract]
Financial Instruments	Financial Instruments Debt Instruments The carrying values of the Notes vary from their fair values. The fair values of the Notes were determined by reference to the quoted market prices of these securities (Level 2 input based on the GAAP fair value hierarchy). The carrying value of the Company’s Term Loan Facility approximates its fair value (Level 3 input based on the GAAP fair value hierarchy). The estimated fair value, as well as the carrying value, of the Company's debt instruments are shown below (in millions): April 4, December 31, Estimated aggregate fair value (1) $ 2,062.3 $ 2,384.6 Aggregate carrying value (1)(2) 2,331.2 2,334.4 (1) Includes Term Loan Facility and Notes (2) Excludes the impact of unamortized debt issuance costs and unamortized original issue premium (discount) Cash, Cash Equivalents and Restricted Cash The Company has on deposit, cash that is legally restricted as to use or withdrawal. A reconciliation of cash, cash equivalents and restricted cash reported on the accompanying condensed consolidated balance sheets to cash, cash equivalents and restricted cash reported on the accompanying condensed consolidated statements of cash flows is shown below (in millions): April 4, March 30, Balance sheet - cash and cash equivalents $ 2,449.1 $ 1,199.4 Restricted cash included in other current assets 11.2 13.9 Restricted cash included in other long-term assets 1.6 7.6 Statement of cash flows - cash, cash equivalents and restricted cash $ 2,461.9 $ 1,220.9 Accounts Receivable On January 1, 2020, the Company adopted Accounting Standards Update ("ASU") 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” using a modified retrospective approach. The standard amends several aspects of the measurement of credit losses related to certain financial instruments, including the replacement of the existing incurred credit loss model and other models with the current expected credit losses ("CECL") model. The cumulative effect of adoption resulted in an increase of $0.8 million in the allowance for credit loss and a corresponding decrease in retained earnings as of January 1, 2020. The Company’s allowance for credit losses on financial assets measured at amortized cost, primarily accounts receivable, reflects management’s estimate of credit losses over the remaining expected life of such assets, measured primarily using historical experience, as well as current conditions and forecasts that affect the collectability of the reported amount. Expected credit losses for newly recognized financial assets, as well as changes to expected credit losses during the period, are recognized in earnings. The Company also considers geographic and segment specific risk factors in the development of expected credit losses. As of April 4, 2020 and December 31, 2019 , accounts receivable are reflected net of reserves of $36.7 million and $36.0 million , respectively. Changes in expected credit losses were not significant in the first three months of 2020. Marketable Equity Securities Marketable equity securities, which the Company accounts for under the fair value option, are included in the accompanying condensed consolidated balance sheets as shown below (in millions): April 4, December 31, Current assets $ 7.7 $ 17.1 Other long-term assets 33.2 42.1 $ 40.9 $ 59.2 Unrealized gains and losses arising from changes in the fair value of the marketable equity securities are recognized in the condensed consolidated statements of comprehensive income (loss) as a component of other expense, net. The fair value of the marketable equity securities is determined by reference to quoted market prices in active markets (Level 1 input based on the GAAP fair value hierarchy). Equity Securities Without Readily Determinable Fair Values As of April 4, 2020 and December 31, 2019 , investments in equity securities without readily determinable fair values of $15.2 million are included in other long-term assets in the accompanying condensed consolidated balance sheets. Such investments are valued at cost, less any impairment, and adjusted for changes resulting from observable, orderly transactions for identical or similar securities. Derivative Instruments and Hedging Activities The Company has used derivative financial instruments, including forwards, futures, options, swaps and other derivative contracts to reduce the effects of fluctuations in foreign exchange rates and interest rates and the resulting variability of the Company’s operating results. The Company is not a party to leveraged derivatives. The Company’s derivative financial instruments are subject to master netting arrangements that provide for the net settlement of contracts, by counterparty, in the event of default or termination. On the date that a derivative contract for a hedging instrument is entered into, the Company designates the derivative as either (1) a hedge of the exposure to changes in the fair value of a recognized asset or liability or of an unrecognized firm commitment (a fair value hedge), (2) a hedge of the exposure of a forecasted transaction or of the variability in the cash flows of a recognized asset or liability (a cash flow hedge), (3) a hedge of a net investment in a foreign operation (a net investment hedge) or (4) a contract not designated as a hedging instrument. For a fair value hedge, the change in the fair value of the derivative is recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) on the same line as the gain or loss on the hedged item attributable to the hedged risk. For a cash flow hedge, the change in the fair value of the derivative is recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. When the underlying hedged transaction is realized, the gain or loss included in accumulated other comprehensive loss is recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) on the same line as the gain or loss on the hedged item attributable to the hedged risk. For a net investment hedge, the change in the fair value of the derivative is recorded in cumulative translation adjustment, which is a component of accumulated other comprehensive loss in the condensed consolidated balance sheets. When the related currency translation adjustment is required to be reclassified, usually upon sale or liquidation of the investment, the gain or loss included in accumulated other comprehensive loss is recorded in earnings. Changes in the fair value of contracts not designated as hedging instruments are recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) as other expense, net. Cash flows attributable to derivatives used to manage foreign currency risks are classified on the same line as the hedged item attributable to the hedged risk in the condensed consolidated statements of cash flows. Upon settlement, cash flows attributable to derivatives designated as net investment hedges are classified as investing activities in the consolidated statements of cash flows. Cash flows attributable to forward starting interest rate swaps are classified as financing activities in the condensed consolidated statements of cash flows. The Company formally documents its hedge relationships, including the identification of the hedge instruments and the related hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. Derivatives are recorded at fair value in other current and long-term assets and other current and long-term liabilities in the consolidated balance sheet. The Company also formally assesses whether a derivative used in a hedge transaction is highly effective in offsetting changes in either the fair value or the cash flows of the hedged item. When it is determined that a hedged transaction is no longer probable to occur, the Company discontinues hedge accounting. Foreign Exchange The Company uses forwards, swaps and other derivative contracts to reduce the effects of fluctuations in foreign exchange rates on known foreign currency exposures. Gains and losses on the derivative instruments are intended to offset gains and losses on the hedged transaction in an effort to reduce exposure to fluctuations in foreign exchange rates. The principal currencies hedged by the Company include the Mexican peso, various European currencies, the Thai baht, the Japanese yen, the Chinese renminbi and the Philippine peso. Foreign currency derivative contracts not designated as hedging instruments consist principally of hedges of cash transactions, intercompany loans and certain other balance sheet exposures. Net Investment Hedges The Company uses cross-currency interest rate swaps, which are designated as net investment hedges of the foreign currency rate exposure of its investment in certain Euro-denominated subsidiaries. In the first quarter of 2020, interest expense in the accompanying consolidated statement of comprehensive income (loss) was offset by $1.6 million related to contra interest expense on these net investment hedges. Balance Sheet Classification The notional amount, estimated aggregate fair value and related balance sheet classification of the Company's foreign currency derivative contracts and net investment hedges are shown below (in millions, except for maturities): April 4, December 31, Fair value of foreign currency contracts designated as cash flow hedges: Other current assets $ 22.4 $ 44.0 Other long-term assets 1.0 7.3 Other current liabilities (94.1 ) (4.5 ) Other long-term liabilities (33.6 ) (0.2 ) (104.3 ) 46.6 Notional amount $ 1,275.9 $ 1,465.8 Outstanding maturities in months, not to exceed 24 24 Fair value of derivatives designated as net investment hedges: Other long-term assets $ 18.6 $ — Other long-term liabilities — (4.4 ) 18.6 (4.4 ) Notional amount $ 300.0 $ 300.0 Outstanding maturities in months, not to exceed 54 57 Fair value of foreign currency contracts not designated as hedging instruments: Other current assets $ 9.5 $ 6.9 Other current liabilities (44.2 ) (3.2 ) (34.7 ) 3.7 Notional amount $ 1,086.3 $ 697.0 Outstanding maturities in months, not to exceed 9 12 Total fair value $ (120.4 ) $ 45.9 Total notional amount $ 2,662.2 $ 2,462.8 Accumulated Other Comprehensive Loss - Derivative Instruments and Hedging Pretax amounts related to foreign currency, net investment hedge and interest rate swap contracts that were recognized in and reclassified from accumulated other comprehensive loss are shown below (in millions): Three Months Ended April 4, March 30, Gains (losses) recognized in accumulated other comprehensive loss: Foreign currency contracts $ (143.3 ) $ 24.8 Net investment hedge contracts 23.0 — Interest rate swap contracts — (14.7 ) (120.3 ) 10.1 (Gains) losses reclassified from accumulated other comprehensive loss to: Net sales (0.1 ) 0.5 Cost of sales (7.6 ) (9.7 ) Interest expense 0.6 — (7.1 ) (9.2 ) Comprehensive income (loss) $ (127.4 ) $ 0.9 As of April 4, 2020 and December 31, 2019 , pretax net gains (losses) of ($108.0) million and $19.4 million , respectively, related to the Company’s derivative instruments and hedging activities were recorded in accumulated other comprehensive loss. During the next twelve month period, net losses expected to be reclassified into earnings are shown below (in millions): Net losses related to foreign currency contracts $ 71.8 Net losses related to interest rate swap contracts 2.4 Total $ 74.2 Such losses will be reclassified at the time that the underlying hedged transactions are realized. Fair Value Measurements GAAP provides that fair value is an exit price, defined as a market-based measurement that represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are based on one or more of the following three valuation techniques: Market: This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income : This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost: This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). Further, GAAP prioritizes the inputs and assumptions used in the valuation techniques described above into a three-tier fair value hierarchy as follows: Level 1: Observable inputs, such as quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability. Level 3: Unobservable inputs that reflect the entity’s own assumptions about the exit price of the asset or liability. Unobservable inputs may be used if there is little or no market data for the asset or liability at the measurement date. The Company discloses fair value measurements and the related valuation techniques and fair value hierarchy level for its assets and liabilities that are measured or disclosed at fair value. Items Measured at Fair Value on a Recurring Basis Fair value measurements and the related valuation techniques and fair value hierarchy level for the Company’s assets and liabilities measured at fair value on a recurring basis as of April 4, 2020 and December 31, 2019 , are shown below (in millions): April 4, 2020 Frequency Asset (Liability) Valuation Technique Level 1 Level 2 Level 3 Foreign currency contracts, net Recurring $ (139.0 ) Market/ Income $ — $ (139.0 ) $ — Net investment hedges Recurring $ 18.6 Market/ Income $ — $ 18.6 $ — Marketable equity securities Recurring $ 40.9 Market $ 40.9 $ — $ — December 31, 2019 Frequency Asset (Liability) Valuation Technique Level 1 Level 2 Level 3 Foreign currency contracts, net Recurring $ 50.3 Market/ Income — 50.3 — Net investment hedges Recurring $ (4.4 ) Market/ Income — (4.4 ) — Marketable equity securities Recurring $ 59.2 Market 59.2 — — The Company determines the fair value of its derivative contracts using quoted market prices to calculate the forward values and then discounts such forward values to the present value. The discount rates used are based on quoted bank deposit or swap interest rates. If a derivative contract is in a net liability position, the Company adjusts these discount rates, if required, by an estimate of the credit spread that would be applied by market participants purchasing these contracts from the Company’s counterparties. If an estimate of the credit spread is required, the Company uses significant assumptions and factors other than quoted market rates, which would result in the classification of its derivative liabilities within Level 3 of the fair value hierarchy. As of April 4, 2020 and December 31, 2019 , there were no derivative contracts that were classified within Level 3 of the fair value hierarchy. In addition, there were no transfers in or out of Level 3 of the fair value hierarchy in the first quarter of 2020 . Items Measured at Fair Value on a Non-Recurring Basis The Company measures certain assets and liabilities at fair value on a non-recurring basis, which are not included in the table above. As these non-recurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. In the first quarter of 2020, the Company completed a quantitative goodwill impairment assessment for one of its reporting units. The fair value estimate of the reporting unit was based on a third-party valuation and management's estimates, using a combination of the discounted cash flow method and guideline public company method. As of April 4, 2020 , there were no additional significant assets or liabilities measured at fair value on a non-recurring basis.

Accounting Changes and Error Corrections [Abstract]
Accounting Pronouncements	Accounting Pronouncements The Company considers the applicability and impact of all ASUs issued by the Financial Accounting Standards Board ("FASB"). The Company considered the ASUs summarized below, effective for 2020: Measurement of Credit Losses on Financial Instruments See Note 18 , " Financial Instruments — Accounts Receivable." Simplifying the Test for Goodwill Impairment Effective January 1, 2020, the standard simplifies the accounting for goodwill impairments and allows a goodwill impairment charge to be based on the amount of a reporting unit's carrying value in excess of its fair value. This eliminates the requirement to calculate the implied fair value of goodwill (i.e., "Step 2" under current guidance). Reference Rate Reform In March 2020, the FASB issued guidance related to reference rate reform. The guidance provides temporary optional expedients and exceptions to the current guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and generally can be applied to applicable contract modifications and hedge relationships through December 31, 2022. The adoption of this guidance is not expected to have a significant impact on the Company's financial statements. The Company considered the ASUs summarized below, effective after 2020: Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The standard simplifies the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company's financial statements.

Accounting Policies [Abstract]
Consolidation	The accompanying condensed consolidated financial statements include the accounts of Lear, a Delaware corporation, and the wholly owned and less than wholly owned subsidiaries controlled by Lear. In addition, Lear consolidates all entities, including variable interest entities, in which it has a controlling financial interest. Investments in affiliates in which Lear does not have control, but does have the ability to exercise significant influence over operating and financial policies, are accounted for under the equity method.
Fiscal Period Reporting	The Company’s annual financial results are reported on a calendar year basis, and quarterly interim results are reported using a thirteen week reporting calendar.
Restructuring	Restructuring costs include employee termination benefits, asset impairment charges and contract termination costs, as well as other incremental costs resulting from the restructuring actions. Employee termination benefits are recorded based on existing union and employee contracts, statutory requirements, completed negotiations and Company policy. Other incremental costs principally include equipment and personnel relocation costs. In addition to restructuring costs, the Company incurs incremental manufacturing inefficiency costs at the operating locations impacted by the restructuring actions during the related restructuring implementation period. Restructuring costs are recognized in the Company’s condensed consolidated financial statements in accordance with GAAP. Generally, charges are recorded as restructuring actions are approved and/or implemented.
Inventories	Inventories are stated at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method. Finished goods and work-in-process inventories include material, labor and manufacturing overhead costs.
Pre-Production Costs Related to Long-Term Supply Agreements	The Company incurs pre-production engineering and development ("E&D") and tooling costs related to the products produced for its customers under long-term supply agreements. The Company expenses all pre-production E&D costs for which reimbursement is not contractually guaranteed by the customer. In addition, the Company expenses all pre-production tooling costs related to customer-owned tools for which reimbursement is not contractually guaranteed by the customer or for which the Company does not have a non-cancelable right to use the tooling.
Long-Term Assets	Property, plant and equipment is stated at cost. Costs associated with the repair and maintenance of the Company’s property, plant and equipment are expensed as incurred. Costs associated with improvements which extend the life, increase the capacity or improve the efficiency or safety of the Company’s property, plant and equipment are capitalized and depreciated over the remaining useful life of the related asset. Depreciable property is depreciated over the estimated useful lives of the assets, using principally the straight-line method.
Impairment of Long-Lived Assets	The Company monitors its long-lived assets for impairment indicators on an ongoing basis in accordance with GAAP. If impairment indicators exist, the Company performs the required impairment analysis by comparing the undiscounted cash flows expected to be generated from the long-lived assets to the related net book values. If the net book value exceeds the undiscounted cash flows, an impairment loss is measured and recognized. In the first quarter of 2020, the Company did not recognize any long-lived asset impairment charges, except in conjunction with its restructuring actions as discussed below. The Company will, however, continue to assess the impact of any significant industry events on the realization of its long-lived assets.
Goodwill	Goodwill is not amortized but is tested for impairment on at least an annual basis. Impairment testing is required more often than annually if an event or circumstance indicates that an impairment is more likely than not to have occurred. In conducting its annual impairment testing, the Company may first perform a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. If not, no further goodwill impairment testing is required. If it is more likely than not that a reporting unit’s fair value is less than its carrying amount, or if the Company elects not to perform a qualitative assessment of a reporting unit, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill recorded. The Company conducts its annual impairment testing as of the first day of its fourth quarte r.
Right-of-Use Assets and Lease Obligations	The Company has operating leases for production, office and warehouse facilities, manufacturing and office equipment and vehicles.
Revenue Recognition	The Company enters into contracts with its customers to provide production parts generally at the beginning of a vehicle’s life cycle. Typically, these contracts do not provide for a specified quantity of products, but once entered into, the Company is often expected to fulfill its customers’ purchasing requirements for the production life of the vehicle. Many of these contracts may be terminated by the Company’s customers at any time. Historically, terminations of these contracts have been minimal. The Company receives purchase orders from its customers, which provide the commercial terms for a particular production part, including price (but not quantities). Contracts may also provide for annual price reductions over the production life of the vehicle, and prices may be adjusted on an ongoing basis to reflect changes in product content/cost and other commercial factors. Revenue is recognized at a point in time when control of the product is transferred to the customer under standard commercial terms, as the Company does not have an enforceable right to payment prior to such transfer. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to in exchange for those products based on the annual purchase orders, annual price reductions and ongoing price adjustments. The Company's customers pay for products received in accordance with payment terms that are customary within the industry. The Company's contracts with its customers do not have significant financing components. The Company records a contract liability for advances received from its customers. As of April 4, 2020 and December 31, 2019 , there were no significant contract liabilities recorded. Further, there were no significant contract liabilities recognized in revenue during the first three months of 2020 . Amounts billed to customers related to shipping and handling costs are included in net sales in the condensed consolidated statements of comprehensive income (loss). Shipping and handling costs are accounted for as fulfillment costs and are included in cost of sales in the condensed consolidated statements of comprehensive income (loss). Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction that are collected by the Company from a customer are excluded from revenue.
Income Taxes	The Company’s current and future provision for income taxes is impacted by the initial recognition of and changes in valuation allowances in certain countries. The Company intends to maintain these allowances until it is more likely than not that the deferred tax assets will be realized. The Company’s future provision for income taxes will include no tax benefit with respect to losses incurred and, except for certain jurisdictions, no tax expense with respect to income generated in these countries until the respective valuation allowances are eliminated. Accordingly, income taxes are impacted by changes in valuation allowances and the mix of earnings among jurisdictions. The Company evaluates the realizability of its deferred tax assets on a quarterly basis. In completing this evaluation, the Company considers all available evidence in order to determine whether, based on the weight of the evidence, a valuation allowance for its deferred tax assets is necessary. Such evidence includes historical results, future reversals of existing taxable temporary differences and expectations for future taxable income (exclusive of the reversal of temporary differences and carryforwards), as well as the implementation of feasible and prudent tax planning strategies. If, based on the weight of the evidence, it is more likely than not that all or a portion of the Company’s deferred tax assets will not be realized, a valuation allowance is recorded. If operating results improve or decline on a continual basis in a particular jurisdiction, the Company’s decision regarding the need for a valuation allowance could change, resulting in either the initial recognition or reversal of a valuation allowance in that jurisdiction, which could have a significant impact on income tax expense in the period recognized and subsequent periods. In determining the provision for income taxes for financial statement purposes, the Company makes certain estimates and judgments, which affect its evaluation of the carrying value of its deferred tax assets, as well as its calculation of certain tax liabilities.
Net Income Per Share Attributable to Lear	Basic net income per share available to Lear common stockholders is computed using the two-class method by dividing net income attributable to Lear, after deducting the redemption adjustment related to the redeemable noncontrolling interest, by the average number of common shares outstanding during the period. Common shares issuable upon the satisfaction of certain conditions pursuant to a contractual agreement are considered common shares outstanding and are included in the computation of basic net income per share available to Lear common stockholders.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest
Segment Reporting	The Company has two reportable operating segments: Seating, which includes complete seat systems and all major seat components, including seat covers and surface materials such as leather and fabric, seat structures and mechanisms, seat foam and headrests, and E-Systems, which includes complete electrical distribution systems, as well as sophisticated electronic control modules, electrification products and connectivity products. Key components in the Company's electrical distribution portfolio include wire harnesses, terminals and connectors and junction boxes for both internal combustion engine and electrification architectures that require management of higher voltage and power. Key components in the Company's electronic control module portfolio include body control modules, wireless receiver and transmitter technology and lighting and audio control modules, as well as products specific to electrification and connectivity trends. Electrification products include charging systems (onboard charging modules and cord set charging equipment), battery electronics (battery disconnect units, cell monitoring supervisory systems and integrated total battery control modules) and other power management modules, including converter and inverter systems. Connectivity products include gateway modules and communication modules to manage both wired and wireless networks and data in vehicles. The other category includes unallocated costs related to corporate headquarters, regional headquarters and the elimination of intercompany activities, none of which meets the requirements for being classified as an operating segment. Corporate and regional headquarters costs include various support functions, such as information technology, advance research and development, corporate finance, legal, executive administration and human resources, as well as advanced engineering expenses. Each of the Company’s operating segments reports its results from operations and makes its requests for capital expenditures directly to the chief operating decision maker. The economic performance of each operating segment is driven primarily by automotive production volumes in the geographic regions in which it operates, as well as by the success of the vehicle platforms for which it supplies products. Also, each operating segment operates in the competitive Tier 1 automotive supplier environment and is continually working with its customers to manage costs and improve quality. The Company’s production processes generally make use of hourly labor, dedicated facilities, sequential manufacturing and assembly processes and commodity raw materials. The Company evaluates the performance of its operating segments based primarily on (i) revenues from external customers, (ii) pretax income before equity in net income of affiliates, interest expense and other expense ("segment earnings") and (iii) cash flows, being defined as segment earnings less capital expenditures plus depreciation and amortization.
Marketable Equity Securities	Unrealized gains and losses arising from changes in the fair value of the marketable equity securities are recognized in the condensed consolidated statements of comprehensive income (loss) as a component of other expense, net. The fair value of the marketable equity securities is determined by reference to quoted market prices in active markets (Level 1 input based on the GAAP fair value hierarchy).
Derivative Instruments and Hedging Activities	The Company uses forwards, swaps and other derivative contracts to reduce the effects of fluctuations in foreign exchange rates on known foreign currency exposures. Gains and losses on the derivative instruments are intended to offset gains and losses on the hedged transaction in an effort to reduce exposure to fluctuations in foreign exchange rates. The principal currencies hedged by the Company include the Mexican peso, various European currencies, the Thai baht, the Japanese yen, the Chinese renminbi and the Philippine pesoThe Company determines the fair value of its derivative contracts using quoted market prices to calculate the forward values and then discounts such forward values to the present value. The discount rates used are based on quoted bank deposit or swap interest rates. If a derivative contract is in a net liability position, the Company adjusts these discount rates, if required, by an estimate of the credit spread that would be applied by market participants purchasing these contracts from the Company’s counterparties. If an estimate of the credit spread is required, the Company uses significant assumptions and factors other than quoted market rates, which would result in the classification of its derivative liabilities within Level 3 of the fair value hierarchy. The Company has used derivative financial instruments, including forwards, futures, options, swaps and other derivative contracts to reduce the effects of fluctuations in foreign exchange rates and interest rates and the resulting variability of the Company’s operating results. The Company is not a party to leveraged derivatives. The Company’s derivative financial instruments are subject to master netting arrangements that provide for the net settlement of contracts, by counterparty, in the event of default or termination. On the date that a derivative contract for a hedging instrument is entered into, the Company designates the derivative as either (1) a hedge of the exposure to changes in the fair value of a recognized asset or liability or of an unrecognized firm commitment (a fair value hedge), (2) a hedge of the exposure of a forecasted transaction or of the variability in the cash flows of a recognized asset or liability (a cash flow hedge), (3) a hedge of a net investment in a foreign operation (a net investment hedge) or (4) a contract not designated as a hedging instrument. For a fair value hedge, the change in the fair value of the derivative is recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) on the same line as the gain or loss on the hedged item attributable to the hedged risk. For a cash flow hedge, the change in the fair value of the derivative is recorded in accumulated other comprehensive loss in the condensed consolidated balance sheets. When the underlying hedged transaction is realized, the gain or loss included in accumulated other comprehensive loss is recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) on the same line as the gain or loss on the hedged item attributable to the hedged risk. For a net investment hedge, the change in the fair value of the derivative is recorded in cumulative translation adjustment, which is a component of accumulated other comprehensive loss in the condensed consolidated balance sheets. When the related currency translation adjustment is required to be reclassified, usually upon sale or liquidation of the investment, the gain or loss included in accumulated other comprehensive loss is recorded in earnings. Changes in the fair value of contracts not designated as hedging instruments are recorded in earnings and reflected in the condensed consolidated statements of comprehensive income (loss) as other expense, net. Cash flows attributable to derivatives used to manage foreign currency risks are classified on the same line as the hedged item attributable to the hedged risk in the condensed consolidated statements of cash flows. Upon settlement, cash flows attributable to derivatives designated as net investment hedges are classified as investing activities in the consolidated statements of cash flows. Cash flows attributable to forward starting interest rate swaps are classified as financing activities in the condensed consolidated statements of cash flows. The Company formally documents its hedge relationships, including the identification of the hedge instruments and the related hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. Derivatives are recorded at fair value in other current and long-term assets and other current and long-term liabilities in the consolidated balance sheet. The Company also formally assesses whether a derivative used in a hedge transaction is highly effective in offsetting changes in either the fair value or the cash flows of the hedged item. When it is determined that a hedged transaction is no longer probable to occur, the Company discontinues hedge accounting.
Fair Value Measurements	GAAP provides that fair value is an exit price, defined as a market-based measurement that represents the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements are based on one or more of the following three valuation techniques: Market: This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities. Income : This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations. Cost: This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost). Further, GAAP prioritizes the inputs and assumptions used in the valuation techniques described above into a three-tier fair value hierarchy as follows: Level 1: Observable inputs, such as quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2: Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability. Level 3: Unobservable inputs that reflect the entity’s own assumptions about the exit price of the asset or liability. Unobservable inputs may be used if there is little or no market data for the asset or liability at the measurement date. The Company discloses fair value measurements and the related valuation techniques and fair value hierarchy level for its assets and liabilities that are measured or disclosed at fair value.
Accounting Pronouncements	Accounting Pronouncements The Company considers the applicability and impact of all ASUs issued by the Financial Accounting Standards Board ("FASB"). The Company considered the ASUs summarized below, effective for 2020: Measurement of Credit Losses on Financial Instruments See Note 18 , " Financial Instruments — Accounts Receivable." Simplifying the Test for Goodwill Impairment Effective January 1, 2020, the standard simplifies the accounting for goodwill impairments and allows a goodwill impairment charge to be based on the amount of a reporting unit's carrying value in excess of its fair value. This eliminates the requirement to calculate the implied fair value of goodwill (i.e., "Step 2" under current guidance). Reference Rate Reform In March 2020, the FASB issued guidance related to reference rate reform. The guidance provides temporary optional expedients and exceptions to the current guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate ("LIBOR") and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and generally can be applied to applicable contract modifications and hedge relationships through December 31, 2022. The adoption of this guidance is not expected to have a significant impact on the Company's financial statements. The Company considered the ASUs summarized below, effective after 2020: Simplifying the Accounting for Income Taxes In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The standard simplifies the accounting for income taxes by eliminating certain exceptions to the general principles in Topic 740 and amends existing guidance to improve consistent application. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The adoption of this standard is not expected to have a significant impact on the Company's financial statements.
