Restructuring and Related Activities [Abstract]
Restructuring	Restructuring Restructuring costs include employee termination benefits, fixed asset impairment charges and contract termination costs, as well as other incremental costs resulting from the restructuring actions. These 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 2019 , the Company recorded charges of $54.3 million in connection with its restructuring actions. These charges consist of $48.6 million recorded as cost of sales and $5.7 million recorded as selling, general and administrative expenses. The restructuring charges consist of employee termination costs of $49.1 million , fixed asset impairment charges of $2.1 million and contract termination costs of $1.5 million , as well as other related costs of $1.6 million . Employee termination benefits were recorded based on existing union and employee contracts, statutory requirements, completed negotiations and Company policy. Fixed asset impairment charges relate to the disposal of buildings, leasehold improvements and/or machinery and equipment with carrying values of $2.1 million in excess of related estimated fair values. The Company expects to incur approximately $51 million of additional restructuring costs related to activities initiated as of March 30, 2019 , 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.

Property, Plant and Equipment [Abstract]
Long-Term Assets	Long-Term Assets Property, Plant and Equipment 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): March 30, December 31, 2018 Land $ 114.9 $ 116.8 Buildings and improvements 817.5 809.3 Machinery and equipment 3,568.8 3,463.3 Construction in progress 349.3 389.3 Total property, plant and equipment 4,850.5 4,778.7 Less – accumulated depreciation (2,257.2 ) (2,180.6 ) Property, plant and equipment, net $ 2,593.3 $ 2,598.1 Depreciation expense was $110.9 million and $107.1 million in the three months ended March 30, 2019 and March 31, 2018 , 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. Except as discussed below, the Company does not believe that there were any indicators that would have resulted in long-lived asset impairment charges as of March 30, 2019 . 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 quarters of 2019 and 2018 , the Company recognized fixed asset impairment charges of $2.1 million and $0.9 million , respectively, in conjunction with its restructuring actions (Note 2 , " Restructuring

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 measured and recognized. The Company conducts its annual impairment testing as of the first day of its fourth quarter. The Company does not believe that there were any indicators that would have resulted in goodwill impairment charges as of March 30, 2019

Leases [Abstract]
Leases	Leases On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases," which requires lessees to record right-of-use assets and corresponding liabilities on the balance sheet, as well as disclose key information regarding leasing arrangements. Adoption of the standard resulted in the recognition of right-of-use assets of $438.1 million and related lease obligations of $445.8 million as of January 1, 2019. The standard did not have a significant impact on the Company's operating results or cash flows. Transition As permitted by the transition guidance, the Company adopted the standard by applying the modified retrospective method without the restatement of comparative periods. Accordingly, the Company has provided disclosures required by prior lease guidance for comparative periods. The Company elected the package of practical expedients, which permits a lessee to not reassess under the new standard its prior conclusions regarding lease identification, lease classification and initial direct costs. The Company did not elect the practical expedient which permits the use of hindsight when determining the lease term and assessing right-of-use assets for impairment. As permitted by the transition guidance, the Company used the remaining lease term as of the date of adoption of the standard to estimate discount rates. As permitted by the standard, the Company elected, for all asset classes, the short-term lease exemption. A short-term lease is a lease that, at the commencement date, has a term of twelve months or less and does not include an option to purchase the underlying asset. Accounting Policy The Company determines if an arrangement contains a lease at inception. The Company elected the practical expedient, for all asset classes, to account for each lease component of a contract and its associated non-lease components as a single lease component, rather than allocating a standalone value to each component of a lease. For purposes of calculating operating lease obligations under the standard, the Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such option. The Company's leases do not contain material residual value guarantees or material restrictive covenants. Operating lease expense is recognized on a straight-line basis over the lease terms. Discount Rate The discount rate used to measure a lease obligation should be the rate implicit in the lease; however, the Company’s operating leases generally do not provide an implicit rate. Accordingly, the Company uses its incremental borrowing rate at lease commencement to determine the present value of lease payments. The incremental borrowing rate is an entity-specific rate which represents the rate of interest a lessee would pay to borrow on a collateralized basis over a similar term with similar payments. Right-of-Use Assets and Lease Obligations The Company has operating leases for production, office and warehouse facilities, manufacturing and office equipment and vehicles.

Leases	Leases On January 1, 2019, the Company adopted Accounting Standards Update ("ASU") 2016-02, "Leases," which requires lessees to record right-of-use assets and corresponding liabilities on the balance sheet, as well as disclose key information regarding leasing arrangements. Adoption of the standard resulted in the recognition of right-of-use assets of $438.1 million and related lease obligations of $445.8 million as of January 1, 2019.

Revenue Recognition

Revenue Recognition	3 Months Ended

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 (some of which is accounted for as variable consideration). The Company does not believe that there will be significant changes to its estimates of variable consideration. 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 March 30, 2019 , there were no significant contract liabilities recorded. Further, there were no significant contract liabilities recognized in revenue during the first three months of 2019 . Amounts billed to customers related to shipping and handling costs are included in net sales in the condensed consolidated statements of comprehensive income. 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. 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.

In addition, the Company recognized tax benefits (expense) related to the significant, discrete items shown below (in millions): Three Months Ended March 30, 2019 March 31, 2018 Restructuring charges and various other items $ 15.6 $ 4.1 Reversal of valuation allowances on deferred tax assets of a foreign subsidiary — 35.1 Share-based compensation 3.2 10.1 Increase in foreign withholding tax on certain undistributed foreign earnings — (22.0 ) Change in tax status of certain affiliates 18.4 — $ 37.2 $ 27.3 In addition, in the first quarter of 2018, the Company recognized a gain of $10.0 million related to obtaining control of an affiliate, for which no tax expense was provided. Excluding the items above, the effective tax rate for the first quarters of 2019 and 2018 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. 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 7, "Income Taxes," to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018

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.

The Company may implement these 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 March 30, 2019 and December 31, 2018 .

Commitments and Contingencies Disclosure [Abstract]
Legal and Other Contingencies	Legal and Other Contingencies As of March 30, 2019 and December 31, 2018 , the Company had recorded reserves for pending legal disputes, including commercial disputes and other matters, of $13.3 million and $11.0 million , respectively. Such reserves reflect amounts recognized in accordance with GAAP and 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 March 30, 2019 , is shown below (in millions): Balance at January 1, 2019 $ 28.5 Expense, net (including changes in estimates) 1.4 Settlements (2.3 ) Foreign currency translation and other 0.1 Balance at March 30, 2019 $ 27.7 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 March 30, 2019 and December 31, 2018 , the Company had recorded environmental reserves of $9.0 million . 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.

Electrification products include charging systems (onboard charging modules, cord set charging equipment and wireless charging systems), 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 independent 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, corporate finance, legal, executive administration and human resources, as well as advanced engineering expenses. 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 (income) expense, net, ("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 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 Three Months Ended March 31, 2018 Seating E-Systems Other Consolidated Revenues from external customers $ 4,329.9 $ 1,403.8 $ — $ 5,733.7 Segment earnings (1) 339.5 190.8 (67.4 ) 462.9 Depreciation and amortization 80.0 36.6 3.6 120.2 Capital expenditures 112.3 48.2 2.3 162.8 Total assets 7,901.5 2,631.3 2,148.4 12,681.2 (1) See definition above 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, (Note 2 , " Restructuring "). For the three months ended March 31, 2018 , segment earnings include restructuring charges of $14.4 million , $1.9 million and $2.1 million in the Seating and E-Systems segments and in the other category, respectively, (Note 2 , " Restructuring ").

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): March 30, December 31, 2018 Estimated aggregate fair value (1) $ 1,971.7 $ 1,921.6 Aggregate carrying value (1) (2) 1,965.6 1,967.2 (1) Term Loan Facility and Notes (excludes "other" debt) (2) Excludes the impact of unamortized original issue discount and debt issuance costs 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 condensed consolidated balance sheets to cash, cash equivalents and restricted cash reported on the condensed consolidated statements of cash flows is shown below (in millions): March 30, March 31, 2018 Balance sheet - cash and cash equivalents $ 1,199.4 $ 1,268.5 Restricted cash included in other current assets 13.9 8.4 Restricted cash included in other long-term assets 7.6 17.6 Statement of cash flows - cash, cash equivalents and restricted cash $ 1,220.9 $ 1,294.5 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): March 30, December 31, 2018 Current assets $ 13.8 $ 4.8 Other long-term assets 37.3 42.5 $ 51.1 $ 47.3 Unrealized gains and losses arising from changes in the fair value of the marketable equity securities are recognized in the accompanying condensed consolidated statements of comprehensive income as a component of other (income) 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 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 statement of comprehensive income 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 sheet. 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 statement of comprehensive income 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 sheet. Changes in the fair value of contracts not designated as hedging instruments are recorded in earnings and reflected in the condensed consolidated statement of comprehensive income as other (income) expense, net. 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. The notional amount, estimated aggregate fair value and related balance sheet classification of the Company's foreign currency derivative contracts are shown below (in millions, except for maturities): March 30, December 31, Fair value of foreign currency contracts designated as cash flow hedges: Other current assets $ 28.0 $ 20.6 Other long-term assets 4.2 2.8 Other current liabilities (3.0 ) (8.4 ) Other long-term liabilities (0.6 ) (2.0 ) 28.6 13.0 Notional amount $ 1,357.2 $ 1,499.0 Outstanding maturities in months, not to exceed 24 24 Fair value of foreign currency contracts not designated as hedging instruments: Other current assets $ 6.5 $ 6.1 Other current liabilities (7.7 ) (4.8 ) (1.2 ) 1.3 Notional amount $ 1,321.4 $ 654.0 Outstanding maturities in months, not to exceed 9 12 Total fair value $ 27.4 $ 14.3 Total notional amount $ 2,678.6 $ 2,153.0 Foreign currency derivative contracts not designated as hedging instruments consist principally of hedges of cash transactions, intercompany loans and certain other balance sheet exposures. Interest Rate Swaps The Company has entered into forward starting interest rate swap contracts to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate. The notional amount, estimated aggregate fair value and related balance sheet classification of the Company's interest rate swap contracts are shown below (in millions, except for maturities): March 30, December 31, Fair value of interest rate swap contracts designated as cash flow hedges: Other current liabilities $ 29.4 $ 14.7 Notional amount $ 500.0 $ 500.0 Outstanding maturities in months, not to exceed 9 3 Accumulated Other Comprehensive Loss - Derivative Instruments and Hedging Pretax amounts related to foreign currency derivative contracts designated as cash flow hedges that were recognized in and reclassified from accumulated other comprehensive loss are shown below (in millions): Three Months Ended March 30, March 31, Gains (losses) recognized in accumulated other comprehensive loss: Foreign currency contracts $ 24.8 $ 50.9 Interest rate swap contracts (14.7 ) — 10.1 50.9 Foreign currency contract (gains) losses reclassified from accumulated other comprehensive loss to: Net sales 0.5 1.7 Cost of sales (9.7 ) (4.8 ) (9.2 ) (3.1 ) Comprehensive income $ 0.9 $ 47.8 As of March 30, 2019 and December 31, 2018 , pretax net losses of approximately $0.8 million and $1.7 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, the Company expects to reclassify into earnings net gains of approximately $22.5 million recorded in accumulated other comprehensive loss as of March 30, 2019 . Such gains 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 March 30, 2019 and December 31, 2018 , are shown below (in millions): March 30, 2019 Frequency Asset (Liability) Valuation Technique Level 1 Level 2 Level 3 Recurring $ 27.4 Market/ Income $ — $ 27.4 $ — Interest rate swap contracts Recurring $ (29.4 ) Market/ Income $ — $ (29.4 ) $ — Marketable equity securities Recurring $ 51.1 Market $ 51.1 $ — $ — December 31, 2018 Frequency Asset (Liability) Valuation Technique Level 1 Level 2 Level 3 Foreign currency contracts, net Recurring $ 14.3 Market/ Income $ — $ 14.3 $ — Interest rate swap contracts Recurring $ (14.7 ) Market/ Income $ — $ (14.7 ) $ — Marketable equity securities Recurring $ 47.3 Market $ 47.3 $ — $ — 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 March 30, 2019 and December 31, 2018 , 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 2019 . 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. As of March 30, 2019

Accounting Changes and Error Corrections [Abstract]
Accounting Pronouncements	Accounting Pronouncements Standards Effective in 2019 Leases In February 2016, the Financial Accounting Standards Board issued ASU 2016-02, "Leases," which requires lessees to record right-of-use assets and corresponding liabilities on the balance sheet, as well as disclose key information regarding leasing arrangements. On January 1, 2019, the Company adopted the standard by applying the modified retrospective method without the restatement of comparative financial information, as permitted by the transition guidance. See Note 8 , " Leases ." Other Standards The Company adopted the ASUs summarized below, none of which significantly impacted its financial statements: Standard Description Effective Date ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The standard allows for the reclassification of "stranded" tax effects as a result of the Act from accumulated other comprehensive income to retained earnings. The Company elected not to reclassify such amounts. The Company reclassifies taxes from accumulated other comprehensive loss to earnings as the items to which the tax effects relate are similarly reclassified. January 1, 2019 ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting The standard aligns measurement and classification guidance for share-based payments to nonemployees with the guidance applicable to employees. Under the new guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. January 1, 2019 Standards Effective After 2019 The Company considered the ASUs summarized below, effective after 2019, none of which are expected to significantly impact its financial statements: Standard Description Effective Date ASU 2016-13 and 2018-19, Measurement of Credit Losses on Financial Instruments The standard changes the impairment model for most financial instruments to an "expected loss" model. The new model will generally result in earlier recognition of credit losses. January 1, 2020 ASU 2017-04, Simplifying the Test for Goodwill Impairment 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 or what is known as "Step 2" under the current guidance. January 1, 2020 ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement The standard eliminates certain fair value disclosures while requiring additional disclosures related to the development of inputs for level 3 of the fair value hierarchy and for entities that use the practical expedient to measure the fair value of certain investments at net asset value. January 1, 2020 ASU 2018-15. Customer's Accounting for Implementation Cost Incurred in a Cloud Computing Arrangement that is a Service Contract The standard requires implementation costs in a cloud computing arrangement that is a service contract to be capitalized and amortized over the non-cancellable term of the contract and any renewals that are reasonably certain. January 1, 2020 ASU 2018-17, Related Party Guidance for Variable Interest Entities The standard changes how entities evaluate decision making fees under the variable interest guidance. January 1, 2020 ASU 2018-18, Collaborative Arrangements The standard requires certain transactions between participants in a collaborative arrangement to be accounted for as revenue under the new revenue standard when the participant is a customer. January 1, 2020 ASU 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans The standard requires specific disclosures for defined benefit plans, including the weighted average interest credit rate for cash balance plans and reasons for significant gains and losses affecting the benefit obligation and plan assets. The standard also eliminates certain other disclosures. January 1, 2021

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event On April 17, 2019, the Company completed the acquisition of Xevo Inc. (“Xevo”), a Seattle-based, Tier 1 automotive supplier of software solutions for cloud, car and mobile devices that are deployed in millions of vehicles worldwide. The Company acquired all of the outstanding shares of Xevo for approximately $320 million on a cash and debt free basis (subject to certain adjustments). In conjunction with the acquisition, the Company issued 16,231 shares of restricted stock and 130,285 restricted stock units to certain Xevo employees who joined the Company. These shares of restricted stock and restricted stock units were issued pursuant to the 2019 Inducement Grant Plan which was adopted by the Company's Board of Directors without stockholder approval pursuant to the inducement exemption provided under the New York Stock Exchange listing rules.

Basis of Presentation (Policies

Basis of Presentation (Policies)	3 Months Ended
	Mar. 30, 2019
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.
Reclassifications	Certain amounts in the prior period’s financial statements have been reclassified to conform to the presentation used in the quarter ended March 30, 2019
Restructuring	Restructuring costs include employee termination benefits, fixed asset impairment charges and contract termination costs, as well as other incremental costs resulting from the restructuring actions. These 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.
Property, Plant and Equipment	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. Except as discussed below, the Company does not believe that there were any indicators that would have resulted in long-lived asset impairment charges as of March 30, 2019
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 measured and recognized. The Company conducts its annual impairment testing as of the first day of its fourth quarter.
Leases	The Company determines if an arrangement contains a lease at inception. The Company elected the practical expedient, for all asset classes, to account for each lease component of a contract and its associated non-lease components as a single lease component, rather than allocating a standalone value to each component of a lease. For purposes of calculating operating lease obligations under the standard, the Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such option. The Company's leases do not contain material residual value guarantees or material restrictive covenants.
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 (some of which is accounted for as variable consideration). The Company does not believe that there will be significant changes to its estimates of variable consideration. 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 March 30, 2019 , there were no significant contract liabilities recorded. Further, there were no significant contract liabilities recognized in revenue during the first three months of 2019 . Amounts billed to customers related to shipping and handling costs are included in net sales in the condensed consolidated statements of comprehensive income. 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.
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.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.
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 portfolios specific to electrification and connectivity trends. Electrification products include charging systems (onboard charging modules, cord set charging equipment and wireless charging systems), 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 independent 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, corporate finance, legal, executive administration and human resources, as well as advanced engineering expenses.
Redeemable Noncontrolling Interests	Redeemable Noncontrolling InterestIn accordance with GAAP, the Company records redeemable noncontrolling interests at the greater of (1) the initial carrying amount adjusted for the noncontrolling interest holder’s share of total comprehensive income or loss and dividends ("noncontrolling interest carrying value") or (2) the redemption value as of and based on conditions existing as of the reporting date. Required redeemable noncontrolling interest adjustments are recorded as an increase to redeemable noncontrolling interests, with an offsetting adjustment to retained earnings.
Marketable Equity Securities	Unrealized gains and losses arising from changes in the fair value of the marketable equity securities are recognized in the accompanying condensed consolidated statements of comprehensive income as a component of other (income) 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 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 statement of comprehensive income 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 sheet. 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 statement of comprehensive income 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 sheet. Changes in the fair value of contracts not designated as hedging instruments are recorded in earnings and reflected in the condensed consolidated statement of comprehensive income as other (income) expense, net.
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.
Accounting Pronouncements	Standards Effective in 2019 Leases In February 2016, the Financial Accounting Standards Board issued ASU 2016-02, "Leases," which requires lessees to record right-of-use assets and corresponding liabilities on the balance sheet, as well as disclose key information regarding leasing arrangements. On January 1, 2019, the Company adopted the standard by applying the modified retrospective method without the restatement of comparative financial information, as permitted by the transition guidance. See Note 8 , " Leases ." Other Standards The Company adopted the ASUs summarized below, none of which significantly impacted its financial statements: Standard Description Effective Date ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The standard allows for the reclassification of "stranded" tax effects as a result of the Act from accumulated other comprehensive income to retained earnings. The Company elected not to reclassify such amounts. The Company reclassifies taxes from accumulated other comprehensive loss to earnings as the items to which the tax effects relate are similarly reclassified. January 1, 2019 ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting The standard aligns measurement and classification guidance for share-based payments to nonemployees with the guidance applicable to employees. Under the new guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. January 1, 2019 Standards Effective After 2019 The Company considered the ASUs summarized below, effective after 2019, none of which are expected to significantly impact its financial statements: Standard Description Effective Date ASU 2016-13 and 2018-19, Measurement of Credit Losses on Financial Instruments The standard changes the impairment model for most financial instruments to an "expected loss" model. The new model will generally result in earlier recognition of credit losses. January 1, 2020 ASU 2017-04, Simplifying the Test for Goodwill Impairment 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 or what is known as "Step 2" under the current guidance. January 1, 2020 ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement The standard eliminates certain fair value disclosures while requiring additional disclosures related to the development of inputs for level 3 of the fair value hierarchy and for entities that use the practical expedient to measure the fair value of certain investments at net asset value. January 1, 2020 ASU 2018-15. Customer's Accounting for Implementation Cost Incurred in a Cloud Computing Arrangement that is a Service Contract The standard requires implementation costs in a cloud computing arrangement that is a service contract to be capitalized and amortized over the non-cancellable term of the contract and any renewals that are reasonably certain. January 1, 2020 ASU 2018-17, Related Party Guidance for Variable Interest Entities The standard changes how entities evaluate decision making fees under the variable interest guidance. January 1, 2020 ASU 2018-18, Collaborative Arrangements The standard requires certain transactions between participants in a collaborative arrangement to be accounted for as revenue under the new revenue standard when the participant is a customer. January 1, 2020 ASU 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans The standard requires specific disclosures for defined benefit plans, including the weighted average interest credit rate for cash balance plans and reasons for significant gains and losses affecting the benefit obligation and plan assets. The standard also eliminates certain other disclosures. January 1, 2021

Accounting Changes and Error Corrections [Abstract]
Schedule of Accounting Pronouncements	The Company considered the ASUs summarized below, effective after 2019, none of which are expected to significantly impact its financial statements: Standard Description Effective Date ASU 2016-13 and 2018-19, Measurement of Credit Losses on Financial Instruments The standard changes the impairment model for most financial instruments to an "expected loss" model. The new model will generally result in earlier recognition of credit losses. January 1, 2020 ASU 2017-04, Simplifying the Test for Goodwill Impairment 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 or what is known as "Step 2" under the current guidance. January 1, 2020 ASU 2018-13, Changes to the Disclosure Requirements for Fair Value Measurement The standard eliminates certain fair value disclosures while requiring additional disclosures related to the development of inputs for level 3 of the fair value hierarchy and for entities that use the practical expedient to measure the fair value of certain investments at net asset value. January 1, 2020 ASU 2018-15. Customer's Accounting for Implementation Cost Incurred in a Cloud Computing Arrangement that is a Service Contract The standard requires implementation costs in a cloud computing arrangement that is a service contract to be capitalized and amortized over the non-cancellable term of the contract and any renewals that are reasonably certain. January 1, 2020 ASU 2018-17, Related Party Guidance for Variable Interest Entities The standard changes how entities evaluate decision making fees under the variable interest guidance. January 1, 2020 ASU 2018-18, Collaborative Arrangements The standard requires certain transactions between participants in a collaborative arrangement to be accounted for as revenue under the new revenue standard when the participant is a customer. January 1, 2020 ASU 2018-14, Changes to the Disclosure Requirements for Defined Benefit Plans The standard requires specific disclosures for defined benefit plans, including the weighted average interest credit rate for cash balance plans and reasons for significant gains and losses affecting the benefit obligation and plan assets. The standard also eliminates certain other disclosures. January 1, 2021 Standard Description Effective Date ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income The standard allows for the reclassification of "stranded" tax effects as a result of the Act from accumulated other comprehensive income to retained earnings. The Company elected not to reclassify such amounts. The Company reclassifies taxes from accumulated other comprehensive loss to earnings as the items to which the tax effects relate are similarly reclassified. January 1, 2019 ASU 2018-07, Improvements to Nonemployee Share-Based Payment Accounting The standard aligns measurement and classification guidance for share-based payments to nonemployees with the guidance applicable to employees. Under the new guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. January 1, 2019
