Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 – Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of Vishay and all of its subsidiaries in which a controlling financial interest is maintained. For those consolidated subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interest in the accompanying consolidated balance sheets. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Investments in affiliates over which the Company does not have significant influence are accounted for by the cost method. All intercompany transactions, accounts, and profits are eliminated. Revenue Recognition The Company recognizes revenue from contracts with customers when it satisfies the performance obligations within the contract. The Company has framework agreements with many of its customers that contain the terms and conditions of future sales, but do not create enforceable rights or obligations. For revenue recognition purposes, the Company considers the combined purchase orders and the terms and conditions contained within such framework agreements to be contracts. Payment terms for the Company's sales are generally less than sixty days. Substantially all of the Company's receivables historically have been and are expected to continue to be collected within twelve months of the transfer of products to the customer and the Company expects this to continue going forward. Accordingly, the Company does not recognize a financing component of the transaction price. Revenue is measured based on the consideration specified in contracts with customers, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies its performance obligations. The Company analyzes its contracts to determine whether the promise in the contract to construct and transfer goods to the customer is a performance obligation that will be satisfied over time or at a point in time. When the Company's performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date, the Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time. The Company has a limited number of contracts for custom products that meet the criteria to recognize revenue over time. The Company's contracts contain two performance obligations: delivery of products and warranty protection. The Company does not sell separate, enhanced, or extended warranty coverage, but through its customary business practices, the Company has created implied service-type warranties, which are accounted for as separate performance obligations. Revenue is allocated between these two performance obligations and recognized as the obligations are satisfied. The allocation of revenue to warranty protection is based on an estimate of expected cost plus margin. The delivery of products performance obligation is satisfied and product sales revenue is recognized when the customer takes control of the products. Warranty revenue is deferred and the warranty protection performance obligation is satisfied and revenue is recognized over the warranty period, which is typically less than twenty four months from sale to end customer. The warranty deferred revenue liability is recorded within Other Accrued Expenses and Other Liabilities on the accompanying consolidated balance sheets. The deferred revenue balance associated with the service-type warranty performance obligations and the components that comprise the change in the deferred revenue balance are not significant. The Company has a broad line of products that it sells to original equipment manufacturers ("OEMs"), electronic manufacturing services ("EMS") companies, which manufacture for OEMs on an outsourcing basis, and independent distributors that maintain large inventories of electronic components for resale to OEMs and EMS companies. The Company recognizes revenue on sales to distributors when the distributor takes control of the products ("sold-to" model). The Company has agreements with distributors that allow distributors a limited credit for unsaleable products, which it terms a "scrap allowance." Consistent with industry practice, the Company also has a "stock, ship and debit" program whereby it considers requests by distributors for credits on previously purchased products that remain in distributors' inventory, to enable the distributors to offer more competitive pricing. In addition, the Company has contractual arrangements whereby it provides distributors with protection against price reductions initiated by the Company after product is sold by the Company to the distributor and prior to resale by the distributor. The Company recognizes the estimated variable consideration to be received as revenue and records a related accrued expense for the consideration not expected to be received, based upon its estimate of product returns, scrap allowances, "stock, ship and debit" credits, and price protection credits that will be attributable to sales recorded through the end of the period. The Company makes these estimates based upon sales levels to its distributors during the period, inventory levels at the distributors, current and projected market conditions, and historical experience under the programs. While the Company utilizes a number of different methodologies to estimate the accruals, all of the methodologies take into account sales levels to distributors during the relevant period, inventory levels at the distributors, current and projected market trends and conditions, recent and historical activity under the relevant programs, changes in program policies, and open requests for credits. These procedures require the exercise of significant judgments. The Company believes that it has a reasonable basis to estimate future credits under the programs. See sales returns and allowances accrual activity in Note 9. The Company pays commissions to external sales representatives on a per-sale basis. Accordingly, these commissions are expensed as incurred because the future amortization period of the asset that the Company otherwise would have recognized is one year or less. Internal staff are not paid commissions. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the product even if the shipping and handling activities are performed after the customer obtains control. The Company does not evaluate whether shipping and handling activities are promised services to its customers. If control transfers and revenue is recognized for the related products before the shipping and handling activities occur, the related costs of those shipping and handling activities is accrued. The Company applies this accounting policy election consistently to similar types of transactions. See disaggregated revenue information in Note 15. Research and Development Expenses Research and development costs are expensed as incurred. The amount charged to expense for research and development (exclusive of purchased in-process research and development) aggregated $69,827, $72,885, and $67,153, for the years ended December 31, 2019, 2018, and 2017, respectively. The Company spends additional amounts for the development of machinery and equipment for new processes and for cost reduction measures. Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances have been established for deferred tax assets which the Company believes do not meet GAAP criteria of “more likely than not” to be realized. This criterion requires a level of judgment regarding future taxable income, which may be revised due to changes in market conditions, tax laws, or other factors. If the Company’s assumptions and estimates change in the future, valuation allowances established may be increased, resulting in increased tax expense. Conversely, if the Company is ultimately able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been established, then the related portion of the valuation allowance can be released, resulting in decreased tax expense. The Company and its subsidiaries are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. The Company adjusts these reserves in light of changing facts and circumstances and the provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. These accruals for tax-related uncertainties are based on management’s best estimate of potential tax exposures. When particular matters arise, a number of years may elapse before such matters are audited by tax authorities and finally resolved. Favorable resolution of such matters could be recognized as a reduction to the Company’s effective tax rate in the year of resolution. Unfavorable resolution of any particular issue could increase the effective tax rate and may require the use of cash in the year of resolution. The amount included in current liabilities on the accompanying consolidated balance sheets reflect only amounts expected to be settled in cash within one year. See Note 5. Cash, Cash Equivalents, and Short-Term Investments Cash and cash equivalents includes demand deposits and highly liquid investments with maturities of three months or less when purchased. Highly liquid investments with original maturities greater than three months, but less than one year are classified as short-term investments. At December 31, 2019 and 2018, the Company’s short-term investments were comprised of time deposits with financial institutions whose original maturity exceeds three months, but less than one year. Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance is determined through an analysis of the aging of accounts receivable and assessments of risk that are based on historical trends and an evaluation of the impact of current economic conditions. The Company evaluates the past-due status of its trade receivables based on contractual terms of sale. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Bad debt expense (income realized upon subsequent collection) was $(592), $2,570, and $301 for the years ended December 31, 2019, 2018, and 2017, respectively. Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or net realizable value. Inventories are adjusted for estimated obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions. Property and Equipment Property and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of seven years to ten years. Buildings and building improvements are being depreciated over useful lives of twenty years to forty years. Construction in progress is not depreciated until the assets are placed in service. The estimated cost to complete construction in progress at December 31, 2019 was approximately $92,000. Depreciation expense was $155,985, $150,056, and $148,883 for the years ended December 31, 2019, 2018, and 2017, respectively. Gains and losses on the disposal of assets which do not qualify for presentation as discontinued operations are included in the determination of operating margin (within selling, general, and administrative expenses). Individually material gains and losses on disposal are separately disclosed in the notes to the consolidated financial statements. Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of a business acquired over the fair value of the related net assets at the date of acquisition. Certain intangible assets may be assigned indefinite useful lives. Goodwill and indefinite-lived intangible assets are not amortized but rather are tested for impairment at least annually. These tests are performed more frequently whenever events or changes in circumstances indicate that the assets might be impaired. The Company's business segments (see Note 15) represent its reporting units for goodwill impairment testing purposes. At December 31, 2019 and 2018, respectively, the Company has no recorded indefinite-lived intangible assets. Definite-lived intangible assets are amortized over their estimated useful lives. Patents and acquired technology are being amortized over useful lives of seven years to twenty-five years. Capitalized software is amortized over periods of three years to ten years, primarily included in costs of products sold on the consolidated statements of operations. Customer relationships are amortized over useful lives of five years to twenty years. Noncompete agreements are amortized over periods of three years to ten years. The Company continually evaluates the reasonableness of the useful lives of these assets. GAAP prescribes a quantitative method for determining goodwill impairment. The Company has the option of performing a qualitative assessment before performing the quantitative impairment test. If it is determined, on the basis of qualitative factors, that the fair value of the reporting unit is not more likely than not less than the carrying amount, the quantitative impairment test is not required. If it is determined that the fair value of the reporting unit is more likely than not less than the carrying amount, the quantitative impairment test is required. The Company determines the fair value of the reporting unit and compares that fair value to the net book value of the reporting unit. The fair value of the reporting unit is determined using various valuation techniques, including a comparable companies market multiple approach and a discounted cash flow analysis (an income approach). If the net book value of the reporting unit were to exceed the fair value, the Company would recognize an impairment charge. Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable or the useful life has changed. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for anticipated disposal costs. Available-for-Sale Securities Short-term investments and other assets reported on the accompanying consolidated balance sheets include time deposits with financial institutions whose original maturity exceeds three months, but less than one year that are classified as held-to-maturity instruments, and investments in marketable securities that are classified as available-for-sale instruments. The available-for-sale instruments include assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans (see Note 11) and assets that are intended to fund a portion of the Company’s other postretirement benefit obligations outside of the U.S. These assets are reported at fair value, based on quoted market prices as of the end of the reporting period. Beginning in 2018, unrealized gains and losses are reported, net of their related tax consequences, as Other Income (Expense) on the consolidated statements of operations. At the time of sale, the assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans, any gains (losses) calculated by the specific identification method are recognized as a reduction (increase) to benefits expense, within selling, general, and administrative expenses. Financial Instruments The Company uses financial instruments in the normal course of its business, including from time to time, derivative financial instruments. Additionally, from time to time, the Company enters into contracts that are not considered derivative financial instruments in their entirety, but that include embedded derivative features. The convertible senior debentures due 2040 and due 2041 contain embedded derivatives that are recorded at fair value on a recurring basis. At December 31, 2019 and 2018, outstanding derivative instruments were not material. Other financial instruments include cash and cash equivalents, held-to-maturity short-term investments, accounts receivable, and notes payable. The carrying amounts of these financial instruments reported on the accompanying consolidated balance sheets approximate their fair values due to the short-term nature of these assets and liabilities. Stock-Based Compensation Compensation costs related to stock-based payment transactions are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity (or liability) instruments issued. Compensation cost is recognized over the period that an officer, employee, or non-employee director is required to provide service in exchange for the award. For awards subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. The Company recognizes compensation cost for restricted stock units (“RSUs”) that are expected to vest and records cumulative adjustments in the period that the expectation changes. Foreign Currency Translation The Company has significant operations outside of the United States. The Company finances its operations in Europe and certain locations in Asia in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and most significant locations in Asia are largely financed in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities on the accompanying consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Translation adjustments do not impact the consolidated results of operations and are reported as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rate for the year. While the translation of revenues and expenses into U.S. dollars does not directly impact the statement of operations, the translation effectively increases or decreases the U.S. dollar equivalent of revenues generated and expenses incurred in those foreign currencies. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated results of operations. Commitments and Contingencies Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. The costs for a specific environmental remediation site are discounted if the aggregate amount of the obligation and the amount and timing of the cash payments for that site are fixed or reliably determinable based upon information derived from the remediation plan for that site. Accrued liabilities for environmental matters recorded at December 31, 2019 and 2018 do not include claims against third parties. Restructuring and Severance Costs Restructuring and severance costs reflect charges resulting from cost reduction programs implemented by the Company. Restructuring and severance costs include exit costs, severance benefits pursuant to an on-going arrangement, voluntary termination compensation under a defined program, and any related pension curtailment and settlement charges. The Company recognizes expense for one-time benefits only after management has committed to a plan, the plan is sufficiently detailed to provide the number, classification, and location of employees to be terminated as well as the expected completion date, the plan has been sufficiently communicated to employees such that they are able to determine the type and amount of benefits they will receive if terminated, and it is unlikely that the plan will be significantly changed or withdrawn. If an employee is not required to render service beyond a minimum retention period, the Company recognizes expense once the aforementioned criteria have been met. If an employee is required to render service beyond a minimum retention period, the Company recognizes expense over the period that the employee is required to render future service. The Company recognizes expense for on-going benefit arrangements when the liability is reasonably estimable and considered probable. The Company recognizes expense for voluntary separation / early retirement when the employee delivers an irrevocable voluntary termination notice pursuant to a defined Company program. The Company recognizes other exit costs as incurred. Self-Insurance Programs The Company uses a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for workers’ compensation, general liability, property damage, director and officers’ liability, and vehicle liability. As part of its self-insurance program for certain risks, the Company created a wholly-owned captive insurance entity in 2007. At December 31, 2019, the captive insurance entity provides only property and general liability insurance, although it is licensed to also provide casualty and directors’ and officers’ insurance. The captive insurance entity had no amounts accrued for outstanding claims at December 31, 2019 and 2018. Certain investments held by the captive insurance entity are restricted primarily for the purpose of potential insurance claims. Such amounts are recorded in other noncurrent assets, and total $10,259 and $11,046 at December 31, 2019 and 2018, respectively, representing required statutory reserves of the captive insurance entity. Convertible Debt Instruments The Company separately accounts for the liability and equity components of convertible debt instruments that may be settled in cash in a manner that reflects the Company’s nonconvertible debt borrowing rate. The liability component at issuance is recognized at fair value, based on the fair value of a similar instrument that does not have a conversion feature. A discount is recorded if debt instruments are issued at a coupon rate which is below the rate of a similar instrument that did not have a conversion feature at issuance. The equity component is based on the excess of the principal amount of the debt instruments over the fair value of the liability component, after adjusting for an allocation of debt issuance costs and the deferred tax impact, and is recorded as capital in excess of par. Debt discounts are amortized as additional non-cash interest expense over the expected life of the debt. Leases As of January 1, 2019, the Company accounts for its leases in accordance with Accounting Standards Codification ("ASC") Topic 842, Leases. See Note 3. Recent Accounting Pronouncements Recent Accounting Guidance Not Yet Adopted In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The ASU is effective for the Company for interim and annual periods beginning on or after January 1, 2020. The Company will adopt the ASU effective January 1, 2020. Based on work performed to date, the Company expects to record the effect of transitioning from an incurred loss model to a current expected credit loss model for certain financial instruments as a cumulative-effect adjustment to January 1, 2020 retained earnings of approximately $1,070. Recent Accounting Guidance Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU is the result of a project between the FASB and the International Accounting Standards Board to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The guidance in ASU No. 2016-02 and all related ASUs is codified in ASC Topic 842. The Company adopted ASC Topic 842 effective January 1, 2019. Upon adoption on January 1, 2019, the Company recognized right of use assets of $91,462 and lease liabilities of $95,784 on the consolidated balance sheet. The difference between the initial right of use asset and lease liability balances recognized upon adoption of ASC Topic 842 is primarily due to accrued lease incentive balances at December 31, 2018. On December 20, 2018, the Company received sale proceeds of $45,500 from a third party buyer and concurrently leased-back its former manufacturing site in Santa Clara, California, under a short-term arrangement, to raze the buildings. Upon adoption of ASC Topic 842, the Company was required to reassess the accounting for these transactions. The transactions did not qualify as a completed sale and leaseback under previous GAAP. However, pursuant to ASC Topic 842’s sale and leaseback guidance, the transaction qualifies as a completed sale. The Company recognized a cumulative-effect adjustment to retained earnings (accumulated deficit) of $23,013, to recognize the sale as of the date of adoption, and derecognized the land, building, and related deferred proceeds, which had been recorded in other accrued expenses. The adoption of the ASU did not have a material impact on the Company's results of operations or cash flows. See Note 3. Reclassifications Certain prior year amounts have been reclassified. Such reclassifications had no effect on reported net earnings (loss) attributable to Vishay stockholders, total assets, stockholders' equity, or the statements of cash flows.

Acquisition and Divestiture Activities [Abstract]
Acquisition and Divestiture Activities	Note 2 - Acquisition and Divestiture Activities As part of its growth strategy, the Company seeks to expand through targeted acquisitions of other manufacturers of electronic components that have established positions in major markets, reputations for product quality and reliability, and product lines with which the Company has substantial marketing and technical expertise. Year ended December 31, 2019 On January 3, 2019, the Company acquired substantially all of the assets of Bi-Metallix, Inc. ("Bi-Metallix"), a U.S.-based, privately-held provider of electron beam continuous strip welding services for $11,862. The Company was a major customer of Bi-Metallix, and the acquired business has been vertically integrated into the Company's Resistors segment. Based on an estimate of their fair values, the Company allocated $2,900 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $3,324 related to this acquisition. The results and operations of this acquisition have been included in the Resistors segment since January 3, 2019. The inclusion of this acquisition did not have a material impact on the Company's consolidated results for the year ended December 31, 2019. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. Year ended December 31, 2018 On February 8, 2018, the Company acquired substantially all of the assets and liabilities of UltraSource, Inc. ("UltraSource"), a U.S.-based, privately-held thin film circuit and thin film interconnect manufacturer, for $13,596. Based on an estimate of their fair values, the Company allocated $6,500 of the purchase price to definite-lived intangible assets. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $4,227 related to this acquisition. The results and operations of this acquisition have been included in the Resistors segment since February 8, 2018. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. On June 11, 2018, the Company acquired EuroPower Holdings Ltd. ("EuroPower") for $2,939, net of cash acquired. EuroPower is a distributor of electronic components in the United Kingdom. After allocating the purchase price to the assets acquired and liabilities assumed based on an estimation of their fair values at the date of acquisition, the Company recorded goodwill of $1,068 related to this acquisition. The goodwill related to this acquisition is included in the Resistors reporting unit for goodwill impairment testing. Had these acquisitions occurred as of the beginning of the periods presented in these consolidated financial statements, the pro forma statements of operations would not be materially different than the consolidated statements of operations presented.

Leases [Abstract]

Leases

Note 3 – Leases

The Company leases buildings and machinery and equipment used for manufacturing and/or sales and administrative purposes. The Company is also party to various service, warehousing, and other agreements that it evaluates for potential embedded leases. Substantially all of the Company’s leases are structured and classified as operating leases. As of January 1, 2019, the Company accounts for its leases in accordance with ASC Topic 842.

The Company leases assets in each region in which it operates. The Company’s leases are generally denominated in the currency of the leased assets' location, which may not be the functional currency of the subsidiary lessee. Accordingly, the Company remeasures its lease liability and recognizes a transactional gain/loss for leases denominated in currencies other than the functional currency of the subsidiary lessee.

The Company recognizes right of use assets and lease liabilities for leases greater than twelve months in duration based on the contract consideration for lease components through the term of the lease and the applicable discount rate. Leases with a duration less than or equal to twelve months are considered short-term leases. The Company does not recognize right of use assets or lease liabilities for short-term leases and classifies the expense as short-term lease expense. Variable lease payments based on an index or rate are included in the right of use assets and lease liabilities based on the effective rates at lease commencement. Changes in the rates or indices do not impact the right of use asset or lease liability and are recognized as a component of lease expense in the statement of operations. Variable lease payments not based on an index or rate are not included in the initial right of use asset and lease liability and are recognized when incurred as a component of lease expense in the statement of operations.

The Company has elected to not separate contract consideration for lease and non-lease components for its building leases. In addition to the noncancellable period of a lease, the Company includes periods covered by extension options it is reasonably certain to exercise, termination options that it is reasonably certain not to exercise, and extension and termination options controlled by the lessor in its determination of the lease term. The Company uses the rate implicit in the contract whenever possible when determining the applicable discount rate. When the implicit rate is not used, the Company employs a portfolio approach based on the duration of the lease. The portfolio lease rates are calculated monthly.

No individual lease is considered significant and there are no leases that have not yet commenced that are considered significant.

The net right of use assets and lease liabilities recognized on the consolidated condensed balance sheet for the Company's operating leases as of December 31, 2019 and the net right of use assets and lease liabilities recognized upon the adoption of ASC Topic 842 on January 1, 2019 are presented below:

	December 31, 2019		January 1, 2019
Right of use assets
Operating Leases
Buildings and improvements	$	87,689	$	86,058
Machinery and equipment		5,473		5,404
Total	$	93,162	$	91,462

Machinery and equipment		2,634		2,823
Total	$	78,511	$	81,823
Total lease liabilities	$	98,728	$	95,784

Lease expense is classified in the statements of operations based on asset use. Total lease cost recognized on the consolidated statements of operations is as follows:

	Year ended
	December 31, 2019
Lease expense
Operating lease expense	$	22,271
Short-term lease expense		2,278
Variable lease expense		95
Total lease expense	$	24,644

The Company paid $21,552 for its operating leases during the year ended December 31, 2019, which are included in operating cash flows on the consolidated statement of cash flows. The weighted-average remaining lease term for the Company's operating leases is 8.9 years and the weighted-average discount rate is 6.1% as of December 31, 2019.

The undiscounted future lease payments for the Company's operating lease liabilities are as follows:

	December 31, 2019
2020	$	20,649
2021		17,906
2022		14,588
2023		12,947
2024		11,924
Thereafter		49,739

The undiscounted future lease payments presented in the table above include payments through the term of the lease, which may include periods beyond the noncancellable term. The difference between the total payments above and the lease liability balance is due to the discount rate used to calculate lease liabilities.

The Company elected to use the package of practical expedients available in ASC Topic 842; and accordingly, did not reassess existing contracts for leases, the classification of existing leases, or initial direct costs for any existing leases. The Company also elected to use the practical expedient available in ASC Topic 842 for land easements.

The Company did not elect the practical expedient available in ASC Topic 842 to use hindsight in determining the lease term. Accordingly, the remaining lease term as of January 1, 2019 was used to calculate the initial right of use asset and lease liability.

Restructuring and Related Activities

Note 4 – Restructuring and Related Activities

The Company places a strong emphasis on controlling its costs and combats general price inflation by continuously improving its efficiency and operating performance. When the ongoing cost containment activities are not adequate, the Company takes actions to maintain its cost competitiveness.

The Company incurred significant restructuring costs in its past to reduce its cost structure. Historically, the Company's primary cost reduction technique was through the transfer of production from high-labor-cost countries to lower-labor-cost countries. Since 2013, the Company's cost reduction programs have primarily focused on reducing fixed costs, including selling, general, and administrative expenses.

In the third fiscal quarter of 2019, the Company announced global cost reduction and management rejuvenation programs as part of its continuous efforts to improve efficiency and operating performance.

The Company also implemented restructuring programs during 2013 - 2017 ("Prior Year Programs"). These programs were substantially completed as of December 31, 2017, though certain amounts were settled in cash during 2018 and 2019.

The following table summarizes restructuring and related expenses which were recognized and reported on a separate line in the accompanying consolidated statements of operations:

	Years ended December 31,
	2019			2017
2019 Global Cost Reduction & Management Rejuvenation Program		$	24,139	$	-
Prior Year Programs			-		11,273
Total		$	24,139	$	11,273

2019 Global Cost Reduction and Management Rejuvenation Programs

The 2019 Global Cost Reduction and Management Rejuvenation Programs are primarily designed to reduce manufacturing fixed costs and selling, general, and administrative costs company-wide, and provide management rejuvenation. The Company expects to incur charges of approximately $25,000, primarily related to cash severance costs, to implement these programs. The Company expects these cost reductions to be fully achieved by December 2020.

The Company incurred $24,139 of restructuring expenses, primarily severance costs, during the year ended December 31, 2019. Cash paid for these programs was $1,330 during the year ended December 31, 2019. Severance benefits are generally paid in a lump sum at cessation of employment. The current portion of the liability is $18,841 and is included in other accrued expenses in the accompanying consolidated balance sheet. The non-current portion of the liability is $4,003 and is included in other liabilities in the accompanying consolidated balance sheet.

Prior Year Programs

The Company incurred $73,398 of restructuring expense, primarily severance, associated with the Prior Year Programs during the period 2013 - 2017, of which $11,273 was incurred in 2017. amounts were incurred during the years ended December 31, 2018 or 2019. These programs were substantially implemented as of December 31, 2017. As of December 31, 2019, the remaining amounts to be paid for the Prior Year Programs is immaterial.

Note 5 – Income Taxes

U.S. Tax Reform: Tax Cuts and Jobs Act

On December 22, 2017, the Tax Cuts and Jobs Act (the "TCJA") was enacted in the United States. The TCJA represents sweeping changes in U.S. tax law. Among the numerous changes in tax law, the TCJA permanently reduced the U.S. corporate income tax rate to 21% beginning in 2018; imposed a one-time transition tax on deferred foreign earnings; established a partial territorial tax system by allowing a 100% dividends received deduction on qualifying dividends paid by foreign subsidiaries; limited deductions for net interest expense; expanded the U.S. taxation of foreign earned income to include "global intangible low-taxed income" ("GILTI") of foreign subsidiaries; and imposed a base erosion anti-abuse minimum tax ("BEAT").

As permitted by SAB No. 118, the tax expense recorded in the fourth fiscal quarter of 2017 due to the enactment of the TCJA was considered "provisional," based on reasonable estimates. As further described below, after additional analysis was completed in 2018, the Company identified additional amounts available to be repatriated to the U.S. and additional information regarding the foreign taxes payable and recorded additional provisional tax expense to accrue the incremental foreign income taxes and withholding taxes payable to foreign jurisdiction. The Company collected and analyzed detailed information about the earnings and profits of its non-U.S. subsidiaries, the related taxes paid, the amounts which could be repatriated, the foreign taxes which may be incurred on repatriation, and the associated impact of these items under the TCJA, including under regulatory guidance issued in 2018, throughout the measurement period. The measurement period ended as of December 31, 2018.

The amount of net tax expense recorded provisionally by the Company in the fourth fiscal quarter of 2017 and adjustments recorded during the measurement period in 2018 that are directly and indirectly related to the enactment of the TCJA are summarized as follows:

				Years ended December 31,
	Total			2018			2017
Remeasurement of net deferred tax liabilities	$	(76,027	)	$	(1,211	)	$	(74,816	)
Transition tax on unremitted foreign earnings		222,983			7,425			215,558
Incremental foreign taxes on assumed repatriation		232,282			19,282			213,000
Reversal of deferred taxes due to cancellation of 2015 repatriation plan		(118,887	)		-			(118,887	)
Total tax expense related to the enactment of the TCJA	$	260,351		$	25,496		$	234,855

As a result of the TCJA, the Company recognized a tax benefit of $76,027 to remeasure its net deferred tax liabilities at the lower, 21% rate.

The TCJA transitioned the U.S. from a worldwide tax system to a territorial tax system. Under previous law, companies could indefinitely defer U.S. income taxation on unremitted foreign earnings. The TCJA imposed a one-time transition tax on deferred foreign earnings of 15.5% for liquid assets and 8% for illiquid assets, payable in defined increments over eight years. As a result of this requirement, the Company recognized provisional tax expense of $215,558 in 2017, and provisionally expected to pay $180,000, net of estimated applicable foreign tax credits, and after utilization of net operating loss and R&D and FTC Credit carryforwards. As a result of additional analysis completed during the measurement period, the Company accrued additional tax expense of $7,425 in 2018 and now expects to pay $184,467. The first installments of $14,757 were paid in 2019 and 2018. These previously deferred foreign earnings may now be repatriated to the United States without additional U.S. federal taxation. However, any such repatriation could incur withholding and other foreign taxes in the source and intervening foreign jurisdictions, and certain U.S. state taxes.

Due to the changes in taxation of dividends received from foreign subsidiaries, and also because of the need to finance the payment of the transition tax, the Company made the determination during the fourth fiscal quarter of 2017 that certain unremitted foreign earnings in Israel, Germany, Austria, and France are no longer permanently reinvested, and recorded provisional tax expense of $213,000 to accrue the incremental foreign income taxes and withholding taxes payable to foreign jurisdictions assuming the repatriation to the United States of these approximately $1,100,000 of available foreign earnings. As a result of additional analysis completed during the measurement period, the Company adjusted the amount of foreign unremitted earnings available from Israel, Germany, Austria, and France to approximately $1,200,000, identified additional information regarding foreign taxes payable, and accrued additional tax expense of $19,282.

The Company repatriated $188,742 and $724,000 to the United States, and paid withholding and foreign taxes of $38,814 and $156,767 in 2019 and 2018, respectively. Substantially all of the amounts repatriated in 2019 were used to repay certain intercompany indebtedness, to pay the U.S. transition tax, and to fund capital expansion projects. Substantially all of the amounts repatriated in 2018 were used to reduce the outstanding balance of the credit facility (see Note 6), to repay certain intercompany indebtedness, and to fund the repurchase of convertible senior debentures (see Note 6).

After completing these phases of cash repatriation, there is approximately $100,000 of unremitted foreign earnings that the Company has deemed not permanently reinvested and thus has accrued foreign withholding and other taxes. The Company continues to evaluate the timing of the reparation of these remaining amounts, and may decide to ultimately not repatriate some of these amounts

There are additional amounts of unremitted foreign earnings in other countries, which continue to be reinvested indefinitely, and the Company has made no provision for incremental foreign income taxes and withholding taxes payable to foreign jurisdictions related to these amounts. Determination of the amount of the unrecognized deferred foreign tax liability for these amounts is not practicable because of the complexities associated with its hypothetical calculation.

During the fourth fiscal quarter of 2015, the Company recognized income tax, including U.S. federal and state income taxes, incremental foreign income taxes, and withholding taxes payable to foreign jurisdictions, on $300,000 of foreign earnings. This tax expense was recognized in 2015 following an evaluation of the Company’s anticipated domestic cash needs over several years and the Company’s most efficient use of liquidity, and with consideration of the amount of cash that could be repatriated to the U.S. efficiently with lesser withholding taxes in foreign jurisdictions. The Company repatriated $38,000 and $46,000 pursuant to this program in 2017 and 2016, respectively. Prior to the enactment of the TCJA, the related deferred tax liability for the 2015 repatriation plan was $118,887. The Company terminated the 2015 cash repatriation plan and recorded a provisional income tax benefit to reverse this deferred tax liability, which was replaced by the liability for the transition tax and foreign income and withholding taxes described above.

The deferred tax liability related to these unremitted foreign earnings is based on the available sources of cash, applicable tax rates, foreign currency exchange rates, and other factors and circumstances, as of each balance sheet date. Changes in these underlying facts and circumstances result in changes in the deferred tax liability balance, which are recorded as tax benefit or expense. Deferred taxes are also reevaluated and adjusted for the impact of certain corporate legal entity reorganization activities that impact repatriation.

Certain provisions of the TCJA had a significant impact on the Company's effective tax rate for the years ended December 31, 2019 and 2018, and are expected to have a significant impact in future periods. Because the various provisions of the TCJA are interrelated, and because of changes in the Company’s operations and changes in the capital structure in response to the TCJA, the impact of any specific provision of the TCJA cannot be isolated. The Company recognized a significant amount of GILTI income in 2019 and 2018, but was able to utilize related foreign tax credits to reduce the impact on the effective tax rate. The Company has elected to account for GILTI tax in the period in which it is incurred and, therefore, does not provide any deferred taxes in the consolidated financial statements at December 31, 2019 or 2018. The inclusion of significant GILTI income was a contributing factor in allowing the Company to avoid a limitation on the deductibility of its U.S. interest expense in 2019 and 2018. The Company was subject to the BEAT minimum tax of $2,900 and $0 in 2019 and 2018, respectively. BEAT could increase the Company’s future tax by disallowing certain otherwise deductible payments from the U.S. to non-U.S. subsidiaries and imposing a minimum tax if greater than the regular tax.

The Company's repurchase of outstanding convertible debentures in 2019 and 2018 (see Note 6) reduced the Company's tax rate.

The Company makes significant judgments regarding the realizability of its deferred tax assets (principally net operating losses and tax credits). The carrying value of deferred tax assets is based on the Company’s assessment that it is more likely than not that the Company will realize these assets after consideration of all available positive and negative evidence. As of December 31, 2019, the Company has generated an excess U.S. foreign tax credit of $60,237. Because the Company does not anticipate sufficient U.S. foreign source income during the carryforward period, the Company has not recognized the benefit of the carryforward as of December 31, 2019.

A reconciliation of income tax expense at the U.S. federal statutory income tax rate to actual income tax provision is as follows:

Income tax expense for the years ended December 31, 2019, 2018, and 2017 includes certain discrete tax items for changes in uncertain tax positions, valuation allowances, tax rates, and other related items. These items total $799 (tax benefit), $39,428 (tax benefit), and $230,618 in 2019, 2018, and 2017, respectively.

For the year ended December 31, 2019, the discrete items include $7,554 related to a tax-basis foreign exchange gain on the settlement of an intercompany loan, which previously had been accounted for at the historical foreign exchange rate (akin to an equity contribution) because the debtor entity did not have the intent or ability to repay such intercompany loan. Currency translation adjustments were recorded in accumulated other comprehensive income, and were not included in U.S. GAAP pre-tax income. The Company’s cash repatriation activity resulted in the ability to repay such intercompany loan. Upon settlement of this intercompany loan, the foreign entity realized a taxable gain. Discrete tax items also include a tax benefit of $1,601 resulting from the early extinguishment of convertible senior debentures, reflecting the reduction in deferred tax liabilities related to the special tax attributes of the debentures, $9,583 (tax benefit) of adjustments to remeasure of deferred taxes related to the cash repatriation program described above, and $2,831 of tax expense for changes in uncertain tax positions.

For the year ended December 31, 2018, the discrete items include $25,496 related to the enactment of the TCJA, as previously described, a tax benefit of $54,877 resulting from the early extinguishment of convertible senior debentures, reflecting the reduction in deferred tax liabilities related to the special tax attributes of the debentures, and $10,047 (tax benefit) of adjustments to remeasure the deferred taxes related to the cash repatriation program described above.

For the year ended December 31, 2017, the discrete items include $234,855 related to the enactment of the TCJA, as previously described; $5,802 (tax benefit) for the periodic remeasurement of the deferred tax liability related to the 2015 cash repatriation program described above, and $1,565 of net tax expense for changes in uncertain tax positions.

At December 31, 2019, the Company had the following significant net operating loss carryforwards for tax purposes:

			Expires

Austria	$	17,485	No expiration
Belgium		158,847	No expiration
Israel		10,707	No expiration
Italy		7,325	No expiration
Japan		7,675		2020 - 2029
Netherlands		12,159		2021 - 2026
The Republic of China (Taiwan)		19,130		2024- 2028

Pennsylvania		655,869		2020 - 2039

At December 31, 2019, the Company had the following significant tax credit carryforwards available:

			Expires

U.S. Foreign Tax Credit	$	60,237		2028 - 2029
California Research Credit		15,642	No expiration

Net income taxes paid were $185,654, $248,958, and $76,900 for the years ended December 31, 2019, 2018, and 2017, respectively. Net income taxes paid for the years ended December 31, 2019 and 2018 include $38,814 and $156,767, respectively, for repatriation activity and $14,757 in each period for the TCJA transition tax.

See Note 19 for a discussion of the tax-related uncertainties for the pre-spin-off period of Vishay Precision Group, Inc. (“VPG”), which was spun off on July 6, 2010.

The following table summarizes changes in the liabilities associated with unrecognized tax benefits:

	Years ended December 31,
	2019			2018			2017

Balance at beginning of year	$	21,241		$	17,056		$	16,805
Addition based on tax positions related to the current year		2,383			4,332			3,911
Addition based on tax positions related to prior years		16,190			2,066			1,837
Currency translation adjustments		1,211			(984	)		915
Reduction based on tax positions related to prior years		-			-			(1,473	)
Reduction for settlements		(3,121	)		(1,229	)		(4,077	)
Reduction for lapses of statute of limitation		(1,036	)		-			(862	)
Balance at end of year	$	36,868		$	21,241		$	17,056

All of the unrecognized tax benefits of $36,868 and $21,241, as of December 31, 2019 and 2018, respectively, would reduce the effective tax rate if recognized.

The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. At December 31, 2019 and 2018, the Company had accrued interest and penalties related to the unrecognized tax benefits of $3,561 and $2,887, respectively. During the years ended December 31, 2019, 2018, and 2017, the Company recognized $1,201, $1,470, and $2,479, respectively, in interest and penalties.

The Company and its subsidiaries file U.S. federal income tax returns, as well as tax returns in multiple states and foreign jurisdictions. The Company's U.S. federal income tax returns are generally subject to audit for years ending on or after December 31, 2016. The IRS may, however, ask for supporting documentation for net operating losses for the years ended December 31, 2013 - 2015, which were utilized in the year ended December 31, 2017. During the years ended December 31, 2019, 2018, and 2017, certain tax examinations were concluded and certain statutes of limitations lapsed. The tax provision for those years includes adjustments related to the resolution of these matters, as reflected in the table above. The tax returns of significant non-U.S. subsidiaries which are currently under examination include India (2004 through 2016), Italy (2017), Germany (2013 through 2016), and Israel (2016 and 2017). The Company and its subsidiaries also file income tax returns in other taxing jurisdictions in the U.S. and around the world, many of which are still open to examination.

The timing of the resolution of income tax examinations is highly uncertain, as are the amounts and timing of tax payments that result from such examinations. These events could cause large fluctuations in the balance sheet classification of current and non-current unrecognized tax benefits. The Company believes that in the next 12 months it is reasonably possible that certain income tax examinations will conclude or the statutes of limitation on certain income tax periods open to examination will expire, or both. Given the uncertainties described above, the Company can only determine an estimate of potential decreases in unrecognized tax benefits ranging from $322 to $4,085.

Credit Facility

On June 5, 2019, the Company entered into a new credit agreement with a consortium of banks led by JPMorgan Chase Bank, N.A., as administrative agent, and the lenders (the "New Credit Facility"), which provides an aggregate commitment of $750,000 of revolving loans available until June 5, 2024. The New Credit Facility replaces Vishay’s previous credit agreement that provided for an aggregate commitment of $640,000, and that was scheduled to mature on December 10, 2020. The New Credit Facility also provides for the ability of Vishay to request up to $300,000 of incremental facilities, subject to the satisfaction of certain conditions, which could take the form of additional revolving commitments, incremental “term loan A” or “term loan B” facilities, or incremental equivalent debt.

Borrowings under the New Credit Facility bear interest at LIBOR plus an interest margin. The applicable interest margin is based on the Company's leverage ratio. Based on the Company's current leverage ratio, borrowings bear interest at LIBOR plus 1.50%, the same as pursuant to the previous credit agreement. The Company also pays a commitment fee, also based on its leverage ratio, on undrawn amounts. The undrawn commitment fee, based on the Company's current leverage ratio, is 0.25% per annum, an improvement of 5 basis points over the previous credit agreement.

The New Credit Facility allows an unlimited amount of defined “Investments,” which include certain intercompany transactions and acquisitions, provided the Company's pro forma leverage ratio is equal to or less than 2.75 to 1.00. If the Company's pro forma leverage ratio is greater than 2.75 to 1.00, such Investments are subject to certain limitations.

The New Credit Facility also allows an unlimited amount of defined "Restricted Payments," which include cash dividends and share repurchases, provided the Company's pro forma leverage ratio is equal to or less than 2.50 to 1.00. If the Company's pro forma leverage ratio is greater than 2.50 to 1.00, the New Credit Facility allows such payments up to $100,000 per annum (subject to a cap of $300,000 for the term of the facility, with up to $25,000 of any unused amount of the $100,000 per annum base available for use in the next succeeding calendar year).

Similar to the previous credit agreement, the borrowings under the New Credit Facility are secured by a lien on substantially all assets, including accounts receivable, inventory, machinery and equipment, and general intangibles (but excluding real estate, intellectual property registered or licensed solely for use in, or arising solely under the laws of, any country other than the United States, assets located solely outside of the United States and deposit and securities accounts), of the Company and certain significant subsidiaries located in the United States, and pledges of stock in certain significant domestic and foreign subsidiaries; and are guaranteed by certain significant subsidiaries.

The New Credit Facility continues to limit or restrict the Company and its subsidiaries, from, among other things, incurring indebtedness, incurring liens on its respective assets, making investments and acquisitions (assuming the Company’s pro forma leverage ratio is greater than 2.75 to 1.00), making asset sales, and paying cash dividends and making other restricted payments (assuming the Company's pro forma leverage ratio is greater than 2.50 to 1.00), and requires the Company to comply with other covenants, including the maintenance of specific financial ratios.

Similar to the previous credit agreement, the New Credit Facility also contains customary events of default, including, but not limited to, failure to pay principal or interest, failure to pay or default under other material debt, material misrepresentation or breach of warranty, violation of certain covenants, a change of control, the commencement of bankruptcy proceedings, the insolvency of the Company or certain of its significant subsidiaries, and the rendering of a judgment in excess of $50,000 against the Company or its subsidiaries. Upon the occurrence of an event of default under the New Credit Facility, the Company's obligations under the credit facility may be accelerated and the lending commitments under the credit facility may be terminated.

At December 31, 2019 and 2018, there was $747,912 and $636,211, respectively, available under the Credit Facility. Letters of credit totaling $2,088 and $3,789 were outstanding at December 31, 2019 and 2018, respectively.

Convertible Debt Instruments

In June 2018, the Company issued $600,000 aggregate principal amount of 2.25% convertible senior notes due 2025 to qualified institutional investors.

The following table summarizes some key facts and terms regarding the outstanding convertible debt instruments as of December 31, 2019:

	Due 2025			Due 2040			Due 2041

Issuance date	June 12, 2018			November 9, 2010			May 13, 2011
Maturity date	June 15, 2025			November 15, 2040			May 15, 2041
Principal amount	$	600,000		$	300		$	16,890
Cash coupon rate (per annum)		2.25	%		2.25	%		2.25	%
Nonconvertible debt borrowing rate at issuance (per annum)		5.50	%		8.00	%		8.375	%
Conversion rate effective December 12, 2019 (per $1 principal amount)		31.8083			80.0018			58.3812
Effective conversion price effective December 12, 2019 (per share)	$	31.44		$	12.50		$	17.13
130% of the conversion price (per share)	$	40.87		$	16.25		$	22.27
Call date		n/a		November 20, 2020			May 20, 2021

The terms of the convertible senior debentures due 2040 and due 2041 are generally congruent. The terms of the fully retired convertible senior debentures due 2042 were also generally congruent to the convertible senior debentures due 2040 and due 2041.

Prior to three months before the maturity date, the holders may convert their convertible senior debentures due 2040 and due 2041 only under the following circumstances: (1) during any fiscal quarter after the first full quarter subsequent to issuance, if the sale price of Vishay common stock reaches 130% of the conversion price for a specified period; (2) the trading price of the debentures falls below 98% of the product of the sale price of Vishay's common stock and the conversion rate for a specified period; (3) Vishay calls any or all of the debentures for redemption, at any time prior to the close of business on the third scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events. The convertible senior debentures due 2040 are currently convertible. The convertible senior debentures due 2041 are not currently convertible.

Prior to December 15, 2024, the holders of the convertible senior notes due 2025 may convert their notes only under the following circumstances: (1) during any fiscal quarter after the fiscal quarter ending September 29, 2018, if the sale price of Vishay common stock reaches 130% of the conversion price for a specified period; (2) the trading price of the notes falls below 98% of the product of the sale price of Vishay's common stock and the conversion rate for a specified period; or (3) upon the occurrence of specified corporate transactions. The convertible senior notes due 2025 are not currently convertible.

At the direction of its Board of Directors, the Company intends, upon future conversion of any of the convertible debt instruments, to repay the principal amounts of the convertible debt instruments in cash and settle any additional amounts in shares of Vishay common stock.

Vishay must provide additional shares upon conversion if there is a “fundamental change” in the business as defined in the indenture governing the debentures.

Vishay may not redeem the convertible senior debentures prior to the respective call dates. On or after the call date and prior to the maturity date, Vishay may redeem for cash all or part of the debentures at a redemption price equal to 100% of the principal amount of the debentures to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, if the last reported sale price of Vishay’s common stock has been at least 150% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period prior to the date on which Vishay provides notice of redemption.

The quarterly cash dividend program of the Company results in adjustments to the conversion rate and effective conversion price for the convertible debt instruments effective as of the ex-dividend date of each cash dividend. The conversion rate and effective conversion price for the convertible senior notes due 2025 is adjusted for quarterly cash dividends to the extent such dividends exceed $0.085 per share of common stock.

GAAP requires an issuer to separately account for the liability and equity components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate when interest costs are recognized in subsequent periods. The resulting discount on the debt is amortized as non-cash interest expense in future periods.

The carrying values of the liability and equity components of the convertible debentures are reflected in the Company’s accompanying consolidated balance sheets as follows:

	Principal amount of the convertible debt		Unamortized discount			Embedded derivative		Carrying value of liability component		Equity component (including temporary equity) - net carrying value

December 31, 2019
Convertible senior notes due 2025	$	600,000		(90,872	)		-	$	509,128	$	85,262

Total	$	636,556	$	(127,149	)	$	70	$	509,477	$	100,354

Interest is payable on the convertible debt instruments semi-annually at the cash coupon rate; however, the remaining debt discount is being amortized as additional non-cash interest expense using an effective annual interest rate equal to the Company’s estimated nonconvertible debt borrowing rate at the time of issuance. In addition to ordinary interest, contingent interest will accrue in certain circumstances relating to the trading price of the convertible senior debentures due 2040 and due 2041 and under certain other circumstances, beginning ten years subsequent to their respective issuance. The convertible senior notes due 2025 do not possess contingent interest features.

Interest expense related to the debentures is reflected on the accompanying consolidated statements of operations for the years ended December 31:

	Contractual coupon interest		Non-cash amortization of debt discount		Non-cash amortization of deferred financing costs		Non-cash change in value of derivative liability			Total interest expense related to the debentures

The Company used substantially all of the net proceeds of the June 2018 issuance of convertible senior notes due 2025 to repurchase $220,000 and $69,060 principal amounts of convertible senior debentures due 2040 and due 2042, respectively. The net carrying value of the debentures repurchased were $89,276 and $29,037, respectively. In accordance with the authoritative accounting guidance for convertible debentures, the aggregate repurchase payment of $584,991 was allocated between the liability ($133,647) and equity (including temporary equity, $451,344) components of the convertible debentures, using the Company's nonconvertible debt borrowing rate at the time of the repurchases. As a result, the Company recognized a loss on extinguishment of convertible debentures of $17,309, including the write-off of a portion of unamortized debt issuance costs.

The Company used a substantial portion of the cash repatriated to the United States in 2018 (see Note 5) to repurchase $53,690, $116,922, and $78,772 principal amounts of convertible senior debentures due 2040, due 2041, and due 2042, respectively. The net carrying value of the debentures repurchased were $22,018, $45,157, and $33,466, respectively. In accordance with the authoritative accounting guidance for convertible debentures, the aggregate repurchase payment of $376,004 was allocated between the liability ($108,059) and equity (including temporary equity, $267,945) components of the convertible debentures, using the Company's nonconvertible debt borrowing rate at the time of the repurchases. As a result, the Company recognized a loss on extinguishment of convertible debentures of $9,274, including the write-off of a portion of unamortized debt issuance costs.

The Company used cash to repurchase $1,010, $16,188 and $2,168 principal amounts of convertible senior debentures due 2040, due 2041, and due 2042, respectively, in 2019. The net carrying value of the debentures repurchased were $417, $6,282, and $924, respectively. In accordance with the authoritative accounting guidance for convertible debentures, the aggregate repurchase payment of $27,863 was allocated between the liability ($9,568) and equity (including temporary equity, $18,295) components of the convertible debentures, using the Company's nonconvertible debt borrowing rate at the time of the repurchase. As a result, the Company recognized a loss on extinguishment of convertible debentures of $2,030, including the write-off of a portion of unamortized debt issuance costs. The convertible senior debentures due 2042 have been fully repurchased, and the trustee has confirmed that the Company has satisfied and discharged its obligations under the indenture governing the convertible senior debentures due 2042.

Note 7 – Stockholders’ Equity

The Company’s Class B common stock carries 10 votes per share while the common stock carries 1 vote per share. Class B shares are transferable only to certain permitted transferees while the common stock is freely transferable. Class B shares are convertible on a one-for-one basis at any time into shares of common stock. Transfers of Class B shares other than to permitted transferees result in the automatic conversion of the Class B shares into common stock.

The Board of Directors may only declare dividends or other distributions with respect to the common stock or the Class B common stock if it grants such dividends or distributions in the same amount per share with respect to the other class of stock. Stock dividends or distributions on any class of stock are payable only in shares of stock of that class. Shares of either common stock or Class B common stock cannot be split, divided, or combined unless the other is also split, divided, or combined equally.

In 2014, the Company's Board of Directors approved the initiation of a quarterly cash dividend program. Cash dividends were paid quarterly in 2019 and 2018 as follows:

Pensions and Other Postretirement Benefits [Abstract]

Pensions and Other Postretirement Benefits

Note 11 – Pensions and Other Postretirement Benefits

The Company maintains various retirement benefit plans. GAAP requires employers to recognize the funded status of a benefit plan, measured as the difference between plan assets at fair value and the benefit obligation, in its balance sheet. The recognition of the funded status on the balance sheet requires employers to recognize actuarial items (such as actuarial gains and losses, prior service costs, and transition obligations) as a component of other comprehensive income, net of tax.

The following table summarizes amounts recorded on the accompanying consolidated balance sheets associated with these various retirement benefit plans:

Defined Benefit Pension Plans

U.S. Pension Plans

The Company maintained several defined benefit pension plans which covered most full-time U.S. employees. These included pension plans which are “qualified” under the Employee Retirement Income Security Act of 1974 (“ERISA”) and the Internal Revenue Code, and “non-qualified” pension plans which provide defined benefits primarily to U.S. employees whose benefits under the qualified pension plan would be limited by ERISA and the Internal Revenue Code. The Company’s principal qualified U.S. pension plan (the Vishay Retirement Plan) was frozen effective January 1, 2009 and terminated in 2016.

The Company’s principal non-qualified U.S. pension plan (the Vishay Non-qualified Retirement Plan) was a contributory pension plan designed to provide similar defined benefits to covered U.S. employees whose benefits under the Vishay Retirement Plan were limited by the Internal Revenue Code. The Vishay Non-qualified Retirement Plan was similar in construction to the Vishay Retirement Plan, except that the plan is not qualified under the Internal Revenue Code.

The Vishay Non-qualified Retirement Plan, like all non-qualified plans, is considered to be unfunded. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund benefit payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to the non-qualified pension plan were $27,012 and $22,409 at December 31, 2019 and 2018, respectively.

In 2008, the Company adopted amendments to the Vishay Non-Qualified Retirement Plan such that effective January 1, 2009, the plan was frozen. Pursuant to these amendments, no new employees may participate in the plans, no further participant contributions were required or permitted, and no further benefits shall accrue after December 31, 2008. Benefits accumulated as of December 31, 2008 will be paid to employees upon or following retirement, and the Company will likely need to make additional cash contributions to the rabbi trust to fund this accumulated benefit obligation.

The Company also maintains other pension plans which provide supplemental defined benefits primarily to former U.S. employees whose benefits under qualified pension plans were limited by the Internal Revenue Code. These non-qualified plans are all non-contributory plans, and are considered to be unfunded.

In 2004, the Company entered into an employment agreement with Dr. Felix Zandman, its Executive Chairman and then-Chief Executive Officer. Pursuant to this agreement, the Company is providing an annual retirement benefit of approximately $614 to his surviving spouse. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund benefit payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to this non-qualified pension plan were $605 and $1,199 at December 31, 2019 and 2018, respectively.

Non-U.S. Pension Plans

The Company provides pension and similar benefits to employees of certain non-U.S. subsidiaries consistent with local practices. Pension benefits earned are generally based on years of service and compensation during active employment.

The following table sets forth a reconciliation of the benefit obligation, plan assets, and funded status related to U.S. and non-U.S. pension plans:

See Note 10 for the pretax, tax effect and after tax amounts included in other comprehensive income during the years ended December 31, 2019, 2018, and 2017. The estimated actuarial items for the defined benefit pensions plans that will be amortized from accumulated other comprehensive loss into net periodic pension cost during 2020 is $8,000.

The following weighted average assumptions were used to determine benefit obligations at December 31 of the respective years:

	2019						2018
	U.S. Plans			Non-U.S. Plans			U.S. Plans			Non-U.S. Plans
Discount rate		3.25	%		1.40	%		4.50	%		1.96	%
Rate of compensation increase		0.00	%		2.24	%		0.00	%		2.17	%

The following weighted average assumptions were used to determine the net periodic pension costs:

	Years ended December 31,
	2019						2018
	U.S. Plans			Non-U.S. Plans			U.S. Plans			Non-U.S. Plans
Discount rate		4.50	%		1.96	%		3.75	%		1.80	%
Rate of compensation increase		0.00	%		2.17	%		0.00	%		2.10	%
Expected return on plan assets		0.00	%		2.77	%		0.00	%		2.95	%

The plans’ expected return on assets is based on management’s expectations of long-term average rates of return to be achieved by the underlying investment portfolios. In establishing this assumption, management considers historical and expected returns for the asset classes in which the plans are invested, advice from pension consultants and investment advisors, and current economic and capital market conditions.

The investment mix between equity securities and fixed income securities is based upon achieving a desired return, balancing higher return, more volatile equity securities, and lower return, less volatile fixed income securities and is adjusted for the expected duration of the obligation and the funded status of the plan. Investment allocations are made across a range of securities, maturities and credit quality. The Company’s non-U.S. defined benefit plan investments are based on local laws and customs. Most plans invest in cash and local government fixed income securities, although plans in certain countries have investments in equity securities. The plans do not invest in securities of Vishay or its subsidiaries. Negative investment returns could ultimately affect the funded status of the plans, requiring additional cash contributions. See Note 18 for further information on the fair value of the plan assets by asset category.

Estimated future benefit payments are as follows:

	U.S. Plans		Non-U.S. Plans

2020	$	1,872	$	15,485
2021		1,870		15,064
2022		8,311		18,071
2023		3,185		16,306
2024		3,183		16,154
2025-2029		17,460		81,415

The Company’s anticipated 2020 contributions for defined benefit pension plans will approximate the expected benefit payments disclosed above.

Other Postretirement Benefits

In the U.S., the Company maintains unfunded non-pension postretirement plans, including medical benefits for certain executives and their surviving spouses, which are funded as costs are incurred. The Company also maintains two unfunded non-pension postretirement plans at two European subsidiaries.

The following table sets forth a reconciliation of the benefit obligation, plan assets, and accrued benefit cost related to U.S. and non-U.S. non-pension defined benefit postretirement plans:

Discount rate		4.50	%		1.60	%		3.75	%		1.50	%
Rate of compensation increase		0.00	%		3.18	%		0.00	%		2.88	%

The impact of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit cost and postretirement benefit obligation is not material.

Estimated future benefit payments are as follows:

	U.S. Plans		Non-U.S. Plans

2020	$	872	$	616
2021		839		251

2023		721		266
2024		670		490
2025-2029		2,440		2,794

As the plans are unfunded, the Company’s anticipated contributions for 2020 are equal to its estimated benefits payments.

Other Retirement Obligations

The Company participates in various other defined contribution and government-mandated retirement plans based on local law or custom. The Company periodically makes required contributions for certain of these plans, whereas other plans are unfunded retirement bonus plans which will be paid at the employee's retirement date. At December 31, 2019 and 2018, the accompanying consolidated balance sheets include $12,871 and $11,272, respectively, within accrued pension and other postretirement costs related to these plans.

The Company’s U.S. employees are eligible to participate in a 401(k) savings plan, which provides for Company matching contributions. The Company’s matching expense for the plans was $6,481, $6,353, and $5,843 for the years ended December 31, 2019, 2018, and 2017, respectively. No material amounts are included in the accompanying consolidated balance sheets at December 31, 2019 and 2018 related to unfunded 401(k) contributions.

Certain key employees participate in a deferred compensation plan. During the years ended December 31, 2019, 2018, and 2017, these employees could defer a portion of their compensation until retirement, or elect shorter deferral periods. The Company maintains a liability within other noncurrent liabilities on its consolidated balance sheets related to these deferrals. The Company maintains a non-qualified trust, referred to as a “rabbi” trust, to fund payments under this plan. Rabbi trust assets are subject to creditor claims under certain conditions and are not the property of employees. Therefore, they are accounted for as other noncurrent assets. Assets held in trust related to the deferred compensation plan at December 31, 2019 and 2018 were approximately $24,531 and $18,162, respectively.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

Note 12 – Stock-Based Compensation

The Company has various stockholder-approved programs which allow for the grant of share-based compensation to officers, employees, and non-employee directors.

The amount of compensation cost related to stock-based payment transactions is measured based on the grant-date fair value of the equity instruments issued. The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. The Company determines compensation cost for restricted stock units ("RSUs"), phantom stock units, and restricted stock based on the grant-date fair value of the underlying common stock adjusted for expected dividends paid over the required vesting period for non-participating awards. Compensation cost is recognized over the period that an officer, employee, or non-employee director provides service in exchange for the award.

The following table summarizes share-based compensation expense recognized:

	Years ended December 31,
	2019		2018		2017

Restricted stock units	$	5,931	$	4,603	$	4,231
Phantom stock units		177		214		163
Total	$	6,108	$	4,817	$	4,394

The Company recognizes compensation cost for RSUs that are expected to vest and records cumulative adjustments in the period that the expectation changes.

The following table summarizes unrecognized compensation cost and the weighted average remaining amortization periods at December 31, 2019 (amortization periods in years):

	Unrecognized Compensation Cost		Weighted Average Remaining Amortization Periods

Restricted stock units	$	3,096		0.8
Phantom stock units		-		0.0
Total	$	3,096

The Company currently expects all performance-based RSUs to vest and all of the associated unrecognized compensation cost for performance-based RSUs presented in the table above to be recognized.

2007 Stock Incentive Program

The Company's 2007 Stock Incentive Program (the "2007 Program"), as amended and restated, was approved by Vishay's stockholders at Vishay's Annual Meeting of Stockholders on May 20, 2014. The 2007 Program permits the grant of up to 6,500,000 shares of restricted stock, unrestricted stock, RSUs, stock options, and phantom stock units, to officers, employees, and non-employee directors of the Company. Such instruments are available for grant until May 20, 2024.

At December 31, 2019, the Company has reserved 2,580,000 shares of common stock for future grants of equity awards pursuant to the 2007 Program. If any outstanding awards are forfeited by the holder or cancelled by the Company, the underlying shares would be available for regrant to others.

Restricted Stock Units

Each RSU entitles the recipient to receive a share of common stock when the RSU vests.

* The number of RSUs vested includes shares that the Company withheld on behalf of employees to satisfy statutory tax withholding requirements.

The number of performance-based RSUs scheduled to vest increases ratably based on the achievement of defined performance criteria between the established target and maximum levels. RSUs with performance-based vesting criteria are expected to vest as follows (number of RSUs in thousands):

Vesting Date	Expected to Vest		Not Expected to Vest		Total
January 1, 2020**		167		-		167
January 1, 2021		141		-		141
January 1, 2022		174		-		174

** The performance vesting criteria for the performance-based RSUs with a vesting date of January 1, 2020 were achieved.

In the event of (i) any termination (other than for cause) after attaining retirement age (as defined in the respective executive's employment arrangement), the executive's outstanding RSUs shall immediately vest and the outstanding performance-based RSUs shall vest on their normal vesting date to the extent applicable performance criteria are realized; and (ii) a change of control of Vishay, all of such executive’s outstanding RSUs and performance-based RSUs shall immediately vest. In the event of voluntary termination by the executive prior to attaining retirement age or termination for cause, the executive’s outstanding RSUs and performance-based RSUs will be forfeited.

Phantom Stock Units

The 2007 Program authorizes the grant of phantom stock units to the extent provided for in the Company's employment agreements with certain executives. Each phantom stock unit entitles the recipient to receive a share of common stock at the individual's termination of employment or any other future date specified in the applicable employment agreement. Phantom stock units participate in dividend distribution on the same basis as the Company's common stock and Class B common stock. Dividend equivalents are issued in the form of additional units of phantom stock. The phantom stock units are fully vested at all times.

The following table summarizes the Company’s phantom stock units activity (number of phantom stock units in thousands):

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 13 – Commitments and Contingencies Environmental Matters The Company is subject to various federal, state, local, and foreign laws and regulations governing environmental matters, including the use, discharge, and disposal of hazardous materials. The Company’s manufacturing facilities are believed to be in substantial compliance with current laws and regulations. Complying with current laws and regulations has not had a material adverse effect on the Company’s financial condition. The Company has engaged environmental consultants and attorneys to assist management in evaluating potential liabilities related to environmental matters. Management assesses the input from these consultants along with other information known to the Company in its effort to continually monitor these potential liabilities. Management assesses its environmental exposure on a site-by-site basis, including those sites where the Company has been named as a “potentially responsible party.” Such assessments include the Company’s share of remediation costs, information known to the Company concerning the size of the hazardous waste sites, their years of operation, and the number of past users and their financial viability. The Company has accrued environmental liabilities of $12,126, of which $6,346 is included in other accrued liabilities on the accompanying consolidated balance sheet, and $5,780 is included in other noncurrent liabilities on the accompanying consolidated balance sheet. While the ultimate outcome of these matters cannot be determined, management does not believe that the final disposition of these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows. The Company’s present and past facilities have been in operation for many years. These facilities have used substances and have generated and disposed of wastes which are or might be considered hazardous. Therefore, it is possible that additional environmental issues may arise in the future, which the Company cannot now predict. Litigation The Company is a party to various claims and lawsuits arising in the normal course of business. The Company is of the opinion that these litigations or claims will not have a material negative effect on its consolidated financial position, results of operations, or cash flows. Semiconductor Foundry Agreements The Company’s Siliconix subsidiary maintains long-term foundry agreements with subcontractors to ensure access to external front-end capacity. Since 2004, Siliconix has maintained long-term foundry arrangements for semiconductor manufacturing with Tower Semiconductor, pursuant to which Siliconix transferred certain technology to Tower Semiconductor and committed to purchase a minimum amount of semiconductor wafers. The Company has minimum purchase commitments pursuant to its current arrangements with Tower Semiconductor and other foundry partners of $38,945, $17,383, $1,560, and $1,560 for the years 2020 through 2024, respectively. The minimum purchase commitments with Tower Semiconductor are based on a 18-month rolling forecast and, accordingly, the 2021 through 2024 minimum purchase commitments will likely increase. The Company has the option to purchase wafers in addition to the minimum commitment and, accordingly, actual purchases may be different than the amounts disclosed above. The Company's 2019 purchases pursuant to its arrangements were less than the minimum purchase commitment and it paid an immaterial penalty. Product Quality Claims The Company is a party to various product quality claims in the normal course of business. See Note 1 for further information on the Company's warranty obligations. Executive Employment Agreements The Company has employment agreements with certain of its senior executives. These employment agreements provide incremental compensation in the event of termination. The Company does not provide any severance or other benefits specifically upon a change in control.

Current Vulnerability Due to Certain Concentrations

Current Vulnerability Due to Certain Concentrations [Abstract]

Current Vulnerability Due to Certain Concentrations

Note 14 – Current Vulnerability Due to Certain Concentrations

Market Concentrations

The Company's largest customer, TTI, Inc., an electronics distributor, represented approximately 10% of consolidated net revenues in 2019 and 2018. The loss of this customer could have a material effect on the results of operations of the Company. No other customers represented greater than 10% of consolidated net revenue in 2019 or 2018.

A material portion of the Company's revenues are derived from the worldwide industrial, automotive, telecommunications, and computing markets. These markets have historically experienced wide variations in demand for end products. If demand for these end products should decrease, the producers thereof could reduce their purchases of the Company's products, which could have an adverse effect on the Company's results of operations and financial position.

Certain subsidiaries and product lines have customers which comprise greater than 10% of the subsidiary's or product line's net revenues. The loss of one of these customers could have a material effect on the results of operations of the subsidiary or product line and financial position of the subsidiary, which could result in an impairment charge which could be material to the Company's consolidated financial statements.

Credit Risk Concentrations

Financial instruments with potential credit risk consist principally of cash and cash equivalents, short-term investments, accounts receivable, and notes receivable. Concentrations of credit risk with respect to receivables are generally limited due to the Company’s large number of customers and their dispersion across many countries and industries. As of December 31, 2019, one customer comprised 19.4% of the Company’s accounts receivable balance. This customer comprised 15.9% of the Company’s accounts receivable balance as of December 31, 2018. No other customer comprised greater than 10% of the Company’s accounts receivable balance as of December 31, 2019 or December 31, 2018. The Company continually monitors the credit risks associated with its accounts receivable and adjusts the allowance for uncollectible accounts accordingly. The credit risk exposure associated with the accounts receivable is limited by the allowance and is not considered material to the financial statements.

The Company maintains cash and cash equivalents and short-term investments with various major financial institutions. The Company is exposed to credit risk related to the potential inability to access liquidity in financial institutions where its cash and cash equivalents and short-term investments are concentrated. As of December 31, 2019, the following financial institutions held over 10% of the Company’s combined cash and cash equivalents and short-term investments balance:

MUFG Bank Ltd.*	16.6	%
HSBC*	16.0	%
JPMorgan*	12.6	%

*Participant in Credit Facility

Sources of Supplies

Many of the Company’s products require the use of raw materials that are produced in only a limited number of regions around the world or are available from only a limited number of suppliers. The Company’s consolidated results of operations may be materially and adversely affected if there are significant price increases for these raw materials, the Company has difficulty obtaining these raw materials, or the quality of available raw materials deteriorates. For periods in which the prices of these raw materials are rising, the Company may be unable to pass on the increased cost to the Company’s customers, which would result in decreased margins for the products in which they are used. For periods in which the prices are declining, the Company may be required to write down its inventory carrying cost of these raw materials which, depending on the extent of the difference between market price and its carrying cost, could have a material adverse effect on the Company’s net earnings.

Vishay is a major consumer of the world’s annual production of tantalum. Tantalum, a metal purchased in powder or wire form, is the principal material used in the manufacture of tantalum capacitors. There are few suppliers that process tantalum ore into capacitor grade tantalum powder.

From time to time, there have been short-term market shortages of raw materials utilized by the Company. While these shortages have not historically adversely affected the Company’s ability to increase production of products containing these raw materials, they have historically resulted in higher raw material costs for the Company. The Company cannot assure that any of these market shortages in the future would not adversely affect the Company’s ability to increase production, particularly during periods of growing demand for the Company’s products.

Certain raw materials used in the manufacture of the Company’s products, such as gold, copper, palladium, and other metals, are traded on active markets and can be subject to significant price volatility. To ensure adequate supply and to provide cost certainty, the Company’s policy is to enter into short-term commitments to purchase defined portions of annual consumption of the raw materials utilized by the Company if market prices decline below budget. If after entering into these commitments, the market prices for these raw materials decline, the Company must recognize losses on these adverse purchase commitments.

Recently enacted rules in the U.S. on conflict minerals, which include tantalum, tungsten, tin, and gold, all of which are used in the Company’s products, could result in increased prices and decreased supply of conflict minerals, which could negatively affect the Company’s consolidated results of operations.

Geographic Concentration

The Company has operations outside the United States, and approximately 73% of revenues earned during 2019 were derived from sales to customers outside the United States. Additionally, as of December 31, 2019, $793,660 of the Company’s cash and cash equivalents and short-term investments were held by subsidiaries outside of the United States. Some of the Company’s products are produced and cash and cash equivalents and short-term investments are held in countries which are subject to risks of political, economic, and military instability. This instability could result in wars, riots, nationalization of industry, currency fluctuations, and labor unrest. These conditions could have an adverse impact on the Company’s ability to operate in these regions and, depending on the extent and severity of these conditions, could materially and adversely affect the Company’s overall financial condition, operating results, and ability to access its liquidity when needed.

As of December 31, 2019 the Company’s cash and cash equivalents and short-term investments were concentrated in the following countries:

Germany	21.5	%
United States	20.2	%
People's Republic of China	17.9	%
Israel	13.5	%
Singapore	11.1	%
The Republic of China (Taiwan)	5.9	%
Malaysia	3.3	%
Other Asia	3.4	%
Other Europe	1.7	%
Other	1.5	%

Certain of the Company's non-U.S. subsidiaries have cash and cash equivalents and short-term investments deposited in U.S. financial institutions.

Vishay has been in operation in Israel for 49 years. The Company has never experienced any material interruption in its operations attributable to these factors, in spite of several Middle East crises, including wars.

Segment and Geographic Data

Segment and Geographic Data [Abstract]

Segment and Geographic Data

Note 15 – Segment and Geographic Data

Vishay is a global manufacturer and supplier of electronic components. Vishay operates, and its chief operating decision maker makes strategic and operating decisions with regards to assessing performance and allocating resources based on, six reporting segments: MOSFETs, Diodes, Optoelectronic Components, Resistors, Inductors, and Capacitors. These segments represent groupings of product lines based on their functionality:

●		Metal oxide semiconductor field effect transistors ("MOSFETs") function as solid state switches to control power.
●		Diodes route, regulate, and block radio frequency, analog, and power signals; protect systems from surges or electrostatic discharge damage; or provide electromagnetic interference filtering.
●		Optoelectronic components emit light, detect light, or do both.
●		Resistors are basic components used in all forms of electronic circuitry to adjust and regulate levels of voltage and current.
●		Inductors use an internal magnetic field to change alternating current phase and resist alternating current.
●		Capacitors store energy and discharge it when needed.

The current six segment alignment reflects a change in reporting structure made during the fourth fiscal quarter of 2019. Prior periods have been recast to separately present Resistors and Inductors.

Vishay's reporting segments generate substantially all of their revenue from product sales to the industrial, automotive, telecommunications, computing, consumer products, power supplies, military and aerospace, and medical end markets. An immaterial portion of revenues are from royalties.

The Company evaluates business segment performance on operating income, exclusive of certain items ("segment operating income"). Only dedicated, direct selling, general, and administrative expenses of the segments are included in the calculation of segment operating income. The Company's calculation of segment operating income excludes such selling, general, and administrative costs as global operations, sales and marketing, information systems, finance and administration groups, as well as restructuring and severance costs, goodwill and long-lived asset impairment charges, and other items. Management believes that evaluating segment performance excluding such items is meaningful because it provides insight with respect to intrinsic operating results of the Company. These items represent reconciling items between segment operating income and consolidated operating income. Business segment assets are the owned or allocated assets used by each business.

The Company also regularly evaluates gross profit by segment to assist in the analysis of consolidated gross profit. The Company considers segment operating income to be the more important metric because it more fully captures the business operations of the segments.

Earnings Per Share [Abstract]

Earnings Per Share

Note 16 – Earnings Per Share

Basic earnings per share is computed using the weighted average number of common shares outstanding during the periods presented. Diluted earnings per share is computed using the weighted average number of common shares outstanding adjusted to include the potentially dilutive effect of stock options and restricted stock units (see Note 12), convertible debt instruments (see Note 6), and other potentially dilutive securities.

The following table sets forth the computation of basic and diluted earnings per share attributable to Vishay stockholders (shares in thousands):

The Company's convertible debt instruments are only convertible for specified periods upon the occurrence of certain events. The convertible debentures due 2040 became convertible subsequent to the December 31, 2019 evaluation of the conversion criteria. In periods that the debentures are not convertible, the certain conditions which could trigger conversion of the remaining debentures have been deemed to be non-substantive, and accordingly, the Company assumes the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive.

At the direction of its Board of Directors, the Company intends, upon conversion, to repay the principal amounts of the convertible debt instruments in cash and settle any additional amounts in shares of Vishay common stock. Accordingly, the convertible instruments are included in the diluted earnings per share computation using the “treasury stock method” (similar to options and warrants) rather than the “if converted method” otherwise required for convertible debt. Under the “treasury stock method,” Vishay calculates the number of shares issuable under the terms of the convertible instruments based on the average market price of Vishay common stock during the period, and that number is included in the total diluted shares figure for the period. If the average market price is less than $12.50, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2040, if the average market price is less than $17.13, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2041, and if the average market price is less than $31.44 no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025.

Fair Value Measurements [Abstract]

Fair Value Measurements

Note 18 – Fair Value Measurements

The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:

Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3: Unobservable inputs that reflect the Company’s own assumptions.

An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis:

	Total Fair Value			Level 1		Level 2		Level 3

As described in Note 6, the Company allocated the aggregate repurchase payment of convertible senior debentures between the associated liability and equity components of the repurchased convertible senior debentures based on a nonrecurring fair value measurement of the convertible senior debentures immediately prior to the repurchases. The nonrecurring fair value measurements are considered Level 3 measurements. See Note 6 for further information on the measurements and inputs.

The Company maintains non-qualified trusts, referred to as “rabbi” trusts, to fund payments under deferred compensation and non-qualified pension plans. Rabbi trust assets consist primarily of marketable securities, classified as available-for-sale, and company-owned life insurance assets. The marketable securities held in the rabbi trusts are valued using quoted market prices on the last business day of the year. The company-owned life insurance assets are valued in consultation with the Company’s insurance brokers using the value of underlying assets of the insurance contracts. The fair value measurement of the marketable securities held in the rabbi trust is considered a Level 1 measurement and the measurement of the company-owned life insurance assets is considered a Level 2 measurement within the fair value hierarchy.

The Company maintains defined benefit retirement plans in certain of its non-U.S. subsidiaries. The assets of the plans are measured at fair value.

Equity securities held by the non-U.S. defined benefit retirement plans consist of equity securities that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the equity securities is considered a Level 1 measurement within the fair value hierarchy.

Fixed income securities held by the non-U.S. defined benefit retirement plans consist of government bonds in the Philippines and India and corporate notes that are valued based on quoted market prices on the last business day of the year. The fair value measurement of the fixed income securities is considered a Level 1 measurement within the fair value hierarchy.

Cash held by the non-U.S. defined benefit retirement plans consists of demand deposits on account in various financial institutions to fund current benefit payments. The carrying amount of the cash approximates its fair value.

The Company holds investments in debt securities that are intended to fund a portion of its pension and other postretirement benefit obligations outside of the U.S. The investments are valued based on quoted market prices on the last business day of the year. The fair value measurement of the investments is considered a Level 1 measurement within the fair value hierarchy.

The convertible senior debentures contain embedded derivative features that GAAP requires to be bifurcated and remeasured each reporting period. Each quarter, the change in the fair value of the embedded derivative features, if any, is recorded in the consolidated statements of operations. The Company uses a derivative valuation model to derive the value of the embedded derivative features. Key inputs into this valuation model are the Company’s current stock price, risk-free interest rates, the stock dividend yield, the stock volatility, and the debentures’ credit spread over London Interbank Offered Rate (LIBOR). The first three aforementioned inputs are based on observable market data and are considered Level 2 inputs while the last two aforementioned inputs are unobservable and thus require management’s judgment and are considered Level 3 inputs. The fair value measurement is considered a Level 3 measurement within the fair value hierarchy.

The fair value of the long-term debt, excluding the derivative liability and capitalized deferred financing costs, at December 31, 2019 and 2018 is approximately $632,200 and $577,200, respectively, compared to its carrying value, excluding the derivative liability and capitalized deferred financing costs, of $515,931 and $509,407, respectively. The Company estimates the fair value of its long-term debt using a combination of quoted market prices for similar financing arrangements and expected future payments discounted at risk-adjusted rates, which are considered level 2 inputs.

At December 31, 2019 and 2018, the Company’s short-term investments were comprised of time deposits with financial institutions that have maturities that exceed 90 days from the date of acquisition; however they all mature within one year from the respective balance sheet dates. The Company's short-term investments are accounted for as held-to-maturity debt instruments, at amortized cost, which approximates their fair value. The investments are funded with excess cash not expected to be needed for operations prior to maturity; therefore, the Company believes it has the intent and ability to hold the short-term investments until maturity. At each reporting date, the Company performs an evaluation to determine if any unrealized losses are other-than-temporary. No other-than-temporary impairments have been recognized on these securities, and there are no unrecognized holding gains or losses for these securities during the periods presented. There have been no transfers to or from the held-to-maturity classification. All decreases in the account balance are due to returns of principal at the securities’ maturity dates. Interest on the securities is recognized as interest income when earned.

At December 31, 2019 and 2018, the Company’s cash and cash equivalents were comprised of demand deposits, time deposits with maturities of three months or less when purchased, and money market funds. The Company estimates the fair value of its cash, cash equivalents, and short-term investments using level 2 inputs. Based on the current interest rates for similar investments with comparable credit risk and time to maturity, the fair value of the Company's cash, cash equivalents, and held-to-maturity short-term investments approximate the carrying amounts reported in the accompanying consolidated balance sheets.

The Company’s financial instruments also include accounts receivable, short-term notes payable, and accounts payable. The carrying amounts for these financial instruments reported in the accompanying consolidated balance sheets approximate their fair values.

Related Party Transactions [Abstract]
Related Party Transactions	Note 19 – Related Party Transactions Vishay Precision Group, Inc. On July 6, 2010, Vishay completed the spin-off of its measurements and foil resistors businesses into an independent, publicly-traded company, Vishay Precision Group, Inc. Vishay’s common stockholders received 1 share of VPG common stock for every 14 shares of Vishay common stock they held on the record date, June 25, 2010, and Vishay’s Class B common stockholders received 1 share of VPG Class B common stock for every 14 shares of Vishay Class B common stock they held on the record date. Following the spin-off, VPG is an independent company and Vishay retains no ownership interest. Relationship with VPG after Spin-off Following the spin-off, VPG and Vishay operate separately, each as independent public companies. Vishay has no ownership interest in VPG. However, Ruta Zandman solely or on a shared basis with Marc Zandman and Ziv Shoshani, all of whom are members of Vishay's Board of Directors, control a large portion of the voting power of both Vishay and VPG. Marc Zandman, Vishay’s Executive Chairman of the Board and an executive officer of Vishay, serves as the Chairman of VPG. Ziv Shoshani, CEO of VPG, serves as a director of Vishay. Additionally, Timothy V. Talbert, a member of Vishay’s Board of Directors is also a member of the Board of Directors of VPG. In connection with the completion of the spin-off, Vishay and its subsidiaries entered into several agreements with VPG and its subsidiaries that govern the relationship of the parties following the spin-off. Among the agreements entered into with VPG and its subsidiaries were a transition services agreement, several lease agreements, and supply agreements. None of the agreements have had nor are expected to have a material impact on Vishay’s financial position, results of operations, or liquidity. Some of these agreements have expired and have not been renewed. Vishay also entered into a trademark license agreement with VPG pursuant to which Vishay granted VPG the license to use certain trademarks, service marks, logos, trade names, entity names, and domain names which include the term “Vishay.” The license granted VPG the limited, exclusive, royalty-free right and license to use certain marks and names incorporating the term “Vishay” in connection with the design, development, manufacture, marketing, provision and performance of certain VPG products that do not compete with any products within Vishay’s product range as constituted immediately following the separation and certain services provided in connection with the products. The license cannot be terminated except as a result of willful misconduct or liquidation bankruptcy of VPG. Until the spin-off, VPG was included in Vishay’s consolidated federal income tax returns and with Vishay and/or certain of Vishay’s subsidiaries in applicable combined or unitary state and local income tax returns. In conjunction with the spin-off, Vishay and VPG entered a tax matters agreement under which Vishay generally will be liable for all U.S. federal, state, local, and foreign income taxes attributable to VPG with respect to taxable periods ending on or before the distribution date except to the extent that VPG has a liability for such taxes on its books at the time of the spin-off. Vishay is also principally responsible for managing any income tax audits by the various tax jurisdictions for pre-spin-off periods. Vishay has fully indemnified VPG of tax exposures arising prior to the spin-off.

Summary of Significant Accounting Policies (Policies)	Dec. 31, 2019
Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Vishay and all of its subsidiaries in which a controlling financial interest is maintained. For those consolidated subsidiaries in which the Company’s ownership is less than 100 percent, the outside stockholders’ interests are shown as noncontrolling interest in the accompanying consolidated balance sheets. Investments in affiliates over which the Company has significant influence but not a controlling interest are carried on the equity basis. Investments in affiliates over which the Company does not have significant influence are accounted for by the cost method. All intercompany transactions, accounts, and profits are eliminated.
Revenue Recognition	Revenue Recognition The Company recognizes revenue from contracts with customers when it satisfies the performance obligations within the contract. The Company has framework agreements with many of its customers that contain the terms and conditions of future sales, but do not create enforceable rights or obligations. For revenue recognition purposes, the Company considers the combined purchase orders and the terms and conditions contained within such framework agreements to be contracts. Payment terms for the Company's sales are generally less than sixty days. Substantially all of the Company's receivables historically have been and are expected to continue to be collected within twelve months of the transfer of products to the customer and the Company expects this to continue going forward. Accordingly, the Company does not recognize a financing component of the transaction price. Revenue is measured based on the consideration specified in contracts with customers, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfies its performance obligations. The Company analyzes its contracts to determine whether the promise in the contract to construct and transfer goods to the customer is a performance obligation that will be satisfied over time or at a point in time. When the Company's performance does not create an asset with an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date, the Company transfers control of a good or service over time and, therefore, satisfies a performance obligation and recognizes revenue over time. The Company has a limited number of contracts for custom products that meet the criteria to recognize revenue over time. The Company's contracts contain two performance obligations: delivery of products and warranty protection. The Company does not sell separate, enhanced, or extended warranty coverage, but through its customary business practices, the Company has created implied service-type warranties, which are accounted for as separate performance obligations. Revenue is allocated between these two performance obligations and recognized as the obligations are satisfied. The allocation of revenue to warranty protection is based on an estimate of expected cost plus margin. The delivery of products performance obligation is satisfied and product sales revenue is recognized when the customer takes control of the products. Warranty revenue is deferred and the warranty protection performance obligation is satisfied and revenue is recognized over the warranty period, which is typically less than twenty four months from sale to end customer. The warranty deferred revenue liability is recorded within Other Accrued Expenses and Other Liabilities on the accompanying consolidated balance sheets. The deferred revenue balance associated with the service-type warranty performance obligations and the components that comprise the change in the deferred revenue balance are not significant. The Company has a broad line of products that it sells to original equipment manufacturers ("OEMs"), electronic manufacturing services ("EMS") companies, which manufacture for OEMs on an outsourcing basis, and independent distributors that maintain large inventories of electronic components for resale to OEMs and EMS companies. The Company recognizes revenue on sales to distributors when the distributor takes control of the products ("sold-to" model). The Company has agreements with distributors that allow distributors a limited credit for unsaleable products, which it terms a "scrap allowance." Consistent with industry practice, the Company also has a "stock, ship and debit" program whereby it considers requests by distributors for credits on previously purchased products that remain in distributors' inventory, to enable the distributors to offer more competitive pricing. In addition, the Company has contractual arrangements whereby it provides distributors with protection against price reductions initiated by the Company after product is sold by the Company to the distributor and prior to resale by the distributor. The Company recognizes the estimated variable consideration to be received as revenue and records a related accrued expense for the consideration not expected to be received, based upon its estimate of product returns, scrap allowances, "stock, ship and debit" credits, and price protection credits that will be attributable to sales recorded through the end of the period. The Company makes these estimates based upon sales levels to its distributors during the period, inventory levels at the distributors, current and projected market conditions, and historical experience under the programs. While the Company utilizes a number of different methodologies to estimate the accruals, all of the methodologies take into account sales levels to distributors during the relevant period, inventory levels at the distributors, current and projected market trends and conditions, recent and historical activity under the relevant programs, changes in program policies, and open requests for credits. These procedures require the exercise of significant judgments. The Company believes that it has a reasonable basis to estimate future credits under the programs. See sales returns and allowances accrual activity in Note 9. The Company pays commissions to external sales representatives on a per-sale basis. Accordingly, these commissions are expensed as incurred because the future amortization period of the asset that the Company otherwise would have recognized is one year or less. Internal staff are not paid commissions. The Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the product even if the shipping and handling activities are performed after the customer obtains control. The Company does not evaluate whether shipping and handling activities are promised services to its customers. If control transfers and revenue is recognized for the related products before the shipping and handling activities occur, the related costs of those shipping and handling activities is accrued. The Company applies this accounting policy election consistently to similar types of transactions. See disaggregated revenue information in Note 15.
Research and Development Expenses	Research and Development Expenses Research and development costs are expensed as incurred. The amount charged to expense for research and development (exclusive of purchased in-process research and development) aggregated $69,827, $72,885, and $67,153, for the years ended December 31, 2019, 2018, and 2017, respectively. The Company spends additional amounts for the development of machinery and equipment for new processes and for cost reduction measures.
Income Taxes	Income Taxes The provision for income taxes is determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances have been established for deferred tax assets which the Company believes do not meet GAAP criteria of “more likely than not” to be realized. This criterion requires a level of judgment regarding future taxable income, which may be revised due to changes in market conditions, tax laws, or other factors. If the Company’s assumptions and estimates change in the future, valuation allowances established may be increased, resulting in increased tax expense. Conversely, if the Company is ultimately able to utilize all or a portion of the deferred tax assets for which a valuation allowance has been established, then the related portion of the valuation allowance can be released, resulting in decreased tax expense. The Company and its subsidiaries are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in evaluating the Company’s tax positions and determining its provision for income taxes. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. The Company establishes reserves for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These reserves are established when the Company believes that certain positions might be challenged despite the Company’s belief that its tax return positions are fully supportable. The Company adjusts these reserves in light of changing facts and circumstances and the provision for income taxes includes the impact of reserve provisions and changes to reserves that are considered appropriate. These accruals for tax-related uncertainties are based on management’s best estimate of potential tax exposures. When particular matters arise, a number of years may elapse before such matters are audited by tax authorities and finally resolved. Favorable resolution of such matters could be recognized as a reduction to the Company’s effective tax rate in the year of resolution. Unfavorable resolution of any particular issue could increase the effective tax rate and may require the use of cash in the year of resolution. The amount included in current liabilities on the accompanying consolidated balance sheets reflect only amounts expected to be settled in cash within one year. See Note 5.
Cash, Cash Equivalents, and Short-Term Investments	Cash, Cash Equivalents, and Short-Term Investments Cash and cash equivalents includes demand deposits and highly liquid investments with maturities of three months or less when purchased. Highly liquid investments with original maturities greater than three months, but less than one year are classified as short-term investments. At December 31, 2019 and 2018, the Company’s short-term investments were comprised of time deposits with financial institutions whose original maturity exceeds three months, but less than one year.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The allowance is determined through an analysis of the aging of accounts receivable and assessments of risk that are based on historical trends and an evaluation of the impact of current economic conditions. The Company evaluates the past-due status of its trade receivables based on contractual terms of sale. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Bad debt expense (income realized upon subsequent collection) was $(592), $2,570, and $301 for the years ended December 31, 2019, 2018, and 2017, respectively.
Inventories	Inventories Inventories are stated at the lower of cost, determined by the first-in, first-out method, or net realizable value. Inventories are adjusted for estimated obsolescence and written down to net realizable value based upon estimates of future demand, technology developments, and market conditions.
Property and Equipment	Property and Equipment Property and equipment is carried at cost and is depreciated principally by the straight-line method based upon the estimated useful lives of the assets. Machinery and equipment are being depreciated over useful lives of seven years to ten years. Buildings and building improvements are being depreciated over useful lives of twenty years to forty years. Construction in progress is not depreciated until the assets are placed in service. The estimated cost to complete construction in progress at December 31, 2019 was approximately $92,000. Depreciation expense was $155,985, $150,056, and $148,883 for the years ended December 31, 2019, 2018, and 2017, respectively. Gains and losses on the disposal of assets which do not qualify for presentation as discontinued operations are included in the determination of operating margin (within selling, general, and administrative expenses). Individually material gains and losses on disposal are separately disclosed in the notes to the consolidated financial statements.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill represents the excess of the cost of a business acquired over the fair value of the related net assets at the date of acquisition. Certain intangible assets may be assigned indefinite useful lives. Goodwill and indefinite-lived intangible assets are not amortized but rather are tested for impairment at least annually. These tests are performed more frequently whenever events or changes in circumstances indicate that the assets might be impaired. The Company's business segments (see Note 15) represent its reporting units for goodwill impairment testing purposes. At December 31, 2019 and 2018, respectively, the Company has no recorded indefinite-lived intangible assets. Definite-lived intangible assets are amortized over their estimated useful lives. Patents and acquired technology are being amortized over useful lives of seven years to twenty-five years. Capitalized software is amortized over periods of three years to ten years, primarily included in costs of products sold on the consolidated statements of operations. Customer relationships are amortized over useful lives of five years to twenty years. Noncompete agreements are amortized over periods of three years to ten years. The Company continually evaluates the reasonableness of the useful lives of these assets. GAAP prescribes a quantitative method for determining goodwill impairment. The Company has the option of performing a qualitative assessment before performing the quantitative impairment test. If it is determined, on the basis of qualitative factors, that the fair value of the reporting unit is not more likely than not less than the carrying amount, the quantitative impairment test is not required. If it is determined that the fair value of the reporting unit is more likely than not less than the carrying amount, the quantitative impairment test is required. The Company determines the fair value of the reporting unit and compares that fair value to the net book value of the reporting unit. The fair value of the reporting unit is determined using various valuation techniques, including a comparable companies market multiple approach and a discounted cash flow analysis (an income approach). If the net book value of the reporting unit were to exceed the fair value, the Company would recognize an impairment charge.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The carrying value of long-lived assets held-and-used, other than goodwill and indefinite-lived intangible assets, is evaluated when events or changes in circumstances indicate the carrying value may not be recoverable or the useful life has changed. The carrying value of a long-lived asset group is considered impaired when the total projected undiscounted cash flows from such asset group are separately identifiable and are less than the carrying value. In that event, a loss is recognized based on the amount by which the carrying value exceeds the fair market value of the long-lived asset group. Fair market value is determined primarily using present value techniques based on projected cash flows from the asset group. Losses on long-lived assets held-for-sale, other than goodwill and indefinite-lived intangible assets, are determined in a similar manner, except that fair market values are reduced for anticipated disposal costs.
Available-for-Sale Securities	Available-for-Sale Securities Short-term investments and other assets reported on the accompanying consolidated balance sheets include time deposits with financial institutions whose original maturity exceeds three months, but less than one year that are classified as held-to-maturity instruments, and investments in marketable securities that are classified as available-for-sale instruments. The available-for-sale instruments include assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans (see Note 11) and assets that are intended to fund a portion of the Company’s other postretirement benefit obligations outside of the U.S. These assets are reported at fair value, based on quoted market prices as of the end of the reporting period. Beginning in 2018, unrealized gains and losses are reported, net of their related tax consequences, as Other Income (Expense) on the consolidated statements of operations. At the time of sale, the assets that are held in trust related to the Company’s non-qualified pension and deferred compensation plans, any gains (losses) calculated by the specific identification method are recognized as a reduction (increase) to benefits expense, within selling, general, and administrative expenses.
Financial Instruments	Financial Instruments The Company uses financial instruments in the normal course of its business, including from time to time, derivative financial instruments. Additionally, from time to time, the Company enters into contracts that are not considered derivative financial instruments in their entirety, but that include embedded derivative features. The convertible senior debentures due 2040 and due 2041 contain embedded derivatives that are recorded at fair value on a recurring basis. At December 31, 2019 and 2018, outstanding derivative instruments were not material. Other financial instruments include cash and cash equivalents, held-to-maturity short-term investments, accounts receivable, and notes payable. The carrying amounts of these financial instruments reported on the accompanying consolidated balance sheets approximate their fair values due to the short-term nature of these assets and liabilities.
Stock-Based Compensation	Stock-Based Compensation Compensation costs related to stock-based payment transactions are recognized in the consolidated financial statements. The amount of compensation cost is measured based on the grant-date fair value of the equity (or liability) instruments issued. Compensation cost is recognized over the period that an officer, employee, or non-employee director is required to provide service in exchange for the award. For awards subject to graded vesting, the Company recognizes expense over the service period for each separately vesting portion of the award as if the award was, in-substance, multiple awards. The Company recognizes compensation cost for restricted stock units (“RSUs”) that are expected to vest and records cumulative adjustments in the period that the expectation changes.
Foreign Currency Translation	Foreign Currency Translation The Company has significant operations outside of the United States. The Company finances its operations in Europe and certain locations in Asia in local currencies, and accordingly, these subsidiaries utilize the local currency as their functional currency. The Company’s operations in Israel and most significant locations in Asia are largely financed in U.S. dollars, and accordingly, these subsidiaries utilize the U.S. dollar as their functional currency. For those subsidiaries where the local currency is the functional currency, assets and liabilities on the accompanying consolidated balance sheets have been translated at the rate of exchange as of the balance sheet date. Translation adjustments do not impact the consolidated results of operations and are reported as a separate component of stockholders’ equity. Revenues and expenses are translated at the average exchange rate for the year. While the translation of revenues and expenses into U.S. dollars does not directly impact the statement of operations, the translation effectively increases or decreases the U.S. dollar equivalent of revenues generated and expenses incurred in those foreign currencies. For those foreign subsidiaries where the U.S. dollar is the functional currency, all foreign currency financial statement amounts are remeasured into U.S. dollars. Exchange gains and losses arising from remeasurement of foreign currency-denominated monetary assets and liabilities are included in the consolidated results of operations.
Commitments and Contingencies	Commitments and Contingencies Liabilities for loss contingencies, including environmental remediation costs, arising from claims, assessments, litigation, fines, penalties, and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated. The costs for a specific environmental remediation site are discounted if the aggregate amount of the obligation and the amount and timing of the cash payments for that site are fixed or reliably determinable based upon information derived from the remediation plan for that site. Accrued liabilities for environmental matters recorded at December 31, 2019 and 2018 do not include claims against third parties.
Restructuring and Severance Costs	Restructuring and Severance Costs Restructuring and severance costs reflect charges resulting from cost reduction programs implemented by the Company. Restructuring and severance costs include exit costs, severance benefits pursuant to an on-going arrangement, voluntary termination compensation under a defined program, and any related pension curtailment and settlement charges. The Company recognizes expense for one-time benefits only after management has committed to a plan, the plan is sufficiently detailed to provide the number, classification, and location of employees to be terminated as well as the expected completion date, the plan has been sufficiently communicated to employees such that they are able to determine the type and amount of benefits they will receive if terminated, and it is unlikely that the plan will be significantly changed or withdrawn. If an employee is not required to render service beyond a minimum retention period, the Company recognizes expense once the aforementioned criteria have been met. If an employee is required to render service beyond a minimum retention period, the Company recognizes expense over the period that the employee is required to render future service. The Company recognizes expense for on-going benefit arrangements when the liability is reasonably estimable and considered probable. The Company recognizes expense for voluntary separation / early retirement when the employee delivers an irrevocable voluntary termination notice pursuant to a defined Company program. The Company recognizes other exit costs as incurred.
Self-Insurance Programs	Self-Insurance Programs The Company uses a combination of insurance and self-insurance mechanisms to provide for the potential liabilities for workers’ compensation, general liability, property damage, director and officers’ liability, and vehicle liability. As part of its self-insurance program for certain risks, the Company created a wholly-owned captive insurance entity in 2007. At December 31, 2019, the captive insurance entity provides only property and general liability insurance, although it is licensed to also provide casualty and directors’ and officers’ insurance. The captive insurance entity had no amounts accrued for outstanding claims at December 31, 2019 and 2018. Certain investments held by the captive insurance entity are restricted primarily for the purpose of potential insurance claims. Such amounts are recorded in other noncurrent assets, and total $10,259 and $11,046 at December 31, 2019 and 2018, respectively, representing required statutory reserves of the captive insurance entity.
Convertible Debt Instruments	Convertible Debt Instruments The Company separately accounts for the liability and equity components of convertible debt instruments that may be settled in cash in a manner that reflects the Company’s nonconvertible debt borrowing rate. The liability component at issuance is recognized at fair value, based on the fair value of a similar instrument that does not have a conversion feature. A discount is recorded if debt instruments are issued at a coupon rate which is below the rate of a similar instrument that did not have a conversion feature at issuance. The equity component is based on the excess of the principal amount of the debt instruments over the fair value of the liability component, after adjusting for an allocation of debt issuance costs and the deferred tax impact, and is recorded as capital in excess of par. Debt discounts are amortized as additional non-cash interest expense over the expected life of the debt.
Leases	Leases As of January 1, 2019, the Company accounts for its leases in accordance with Accounting Standards Codification ("ASC") Topic 842, Leases. See Note 3.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Guidance Not Yet Adopted In June 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The ASU is effective for the Company for interim and annual periods beginning on or after January 1, 2020. The Company will adopt the ASU effective January 1, 2020. Based on work performed to date, the Company expects to record the effect of transitioning from an incurred loss model to a current expected credit loss model for certain financial instruments as a cumulative-effect adjustment to January 1, 2020 retained earnings of approximately $1,070. Recent Accounting Guidance Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The ASU is the result of a project between the FASB and the International Accounting Standards Board to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The guidance in ASU No. 2016-02 and all related ASUs is codified in ASC Topic 842. The Company adopted ASC Topic 842 effective January 1, 2019. Upon adoption on January 1, 2019, the Company recognized right of use assets of $91,462 and lease liabilities of $95,784 on the consolidated balance sheet. The difference between the initial right of use asset and lease liability balances recognized upon adoption of ASC Topic 842 is primarily due to accrued lease incentive balances at December 31, 2018. On December 20, 2018, the Company received sale proceeds of $45,500 from a third party buyer and concurrently leased-back its former manufacturing site in Santa Clara, California, under a short-term arrangement, to raze the buildings. Upon adoption of ASC Topic 842, the Company was required to reassess the accounting for these transactions. The transactions did not qualify as a completed sale and leaseback under previous GAAP. However, pursuant to ASC Topic 842’s sale and leaseback guidance, the transaction qualifies as a completed sale. The Company recognized a cumulative-effect adjustment to retained earnings (accumulated deficit) of $23,013, to recognize the sale as of the date of adoption, and derecognized the land, building, and related deferred proceeds, which had been recorded in other accrued expenses. The adoption of the ASU did not have a material impact on the Company's results of operations or cash flows. See Note 3.
Reclassifications	Reclassifications Certain prior year amounts have been reclassified. Such reclassifications had no effect on reported net earnings (loss) attributable to Vishay stockholders, total assets, stockholders' equity, or the statements of cash flows.

Earnings Per Share [Abstract]
Discussion on convertible debt included in computation of earnings per share diluted	The Company's convertible debt instruments are only convertible for specified periods upon the occurrence of certain events. The convertible debentures due 2040 became convertible subsequent to the December 31, 2019 evaluation of the conversion criteria. In periods that the debentures are not convertible, the certain conditions which could trigger conversion of the remaining debentures have been deemed to be non-substantive, and accordingly, the Company assumes the conversion of these instruments in its diluted earnings per share computation during periods in which they are dilutive. At the direction of its Board of Directors, the Company intends, upon conversion, to repay the principal amounts of the convertible debt instruments in cash and settle any additional amounts in shares of Vishay common stock. Accordingly, the convertible instruments are included in the diluted earnings per share computation using the “treasury stock method” (similar to options and warrants) rather than the “if converted method” otherwise required for convertible debt. Under the “treasury stock method,” Vishay calculates the number of shares issuable under the terms of the convertible instruments based on the average market price of Vishay common stock during the period, and that number is included in the total diluted shares figure for the period. If the average market price is less than $12.50, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2040, if the average market price is less than $17.13, no shares are included in the diluted earnings per share computation for the convertible senior debentures due 2041, and if the average market price is less than $31.44 no shares are included in the diluted earnings per share computation for the convertible senior notes due 2025.

Fair Value Measurements (Policies)	12 Months Ended
Fair Value Measurements (Policies)	Dec. 31, 2019
Fair Value Measurements [Abstract]
Fair Value of Financial Instruments, Policy	The fair value measurement accounting guidance establishes a valuation hierarchy of the inputs used to measure fair value. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels: Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Level 3: Unobservable inputs that reflect the Company’s own assumptions. An asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
