Organization Consolidation And Presentation Of Financial Statements [Abstract]

Overview

Note 1 – Overview

Gentherm Incorporated is a global developer and marketer of innovative thermal management technologies for a broad range of heating and cooling and temperature control applications. Unless the context otherwise requires, the terms “Gentherm”, “Company”, “we”, “us” and “our” used herein refer to Gentherm Incorporated and its consolidated subsidiaries. Our products provide solutions for automotive passenger climate comfort and convenience, battery thermal management and cell connecting systems, as well as patient temperature management within the health care industry. Our automotive products can be found in the vehicles of nearly all major automotive manufacturers operating in North America and Europe, and several major automotive manufacturers in Asia. The Company operates in locations aligned with its major customers’ product strategies to provide locally enhanced design, integration and production capabilities. The Company is also developing a number of new technologies and products that will help enable improvements to existing products and to create new product applications for existing and new markets.

On February 1, 2019, the Company completed the divestiture of its environmental test equipment business, Cincinnati Sub Zero industrial chamber business (“CSZ-IC”) and on October 1, 2019, the Company completed the divestiture of its remote power generation systems business, Gentherm Global Power Technologies (“GPT”). The Company’s consolidated condensed financial statements herein include the results of CSZ-IC and GPT through their respective dates of divestiture. CSZ-IC and GPT are not subject to discontinued operations classification.

On April 1, 2019, Gentherm acquired Stihler Electronic GmbH (“Stihler”), a leading developer and manufacturer of patient and blood temperature management systems. The acquisition was accounted for as a business combination.

Basis of Presentation

The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments), considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year.

In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances arising from the COVID-19 pandemic that would require us to update our estimates, judgments or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained. As a result, actual results may differ significantly from our estimates, and any such differences may be material to our financial statements.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]

New Accounting Pronouncements

Note 2 – New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Expected Credit Losses

In June 2016, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2016-13 as of January 1, 2020 and there was no significant

impact on its consolidated condensed financial statements and related disclosures as a result. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted.

Cloud Computing Arrangements That Are Service Contracts

In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-15 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result.

Fair Value Measurement

In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 removes certain disclosure requirements, including (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the policy for timing of transfer between levels, and (iii) the valuation processes for Level 3 fair value measurements. ASU 2018-13 also adds new disclosure requirements, including (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and (ii) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-13 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result.

Recently Issued Accounting Pronouncements Not Yet Adopted

Retirement Benefits

In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans.” ASU 2018-14 removes certain disclosure requirements, including (i) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, and (ii) the amount and timing of plan assets expected to be returned to the employer. ASU 2018-14 also adds new disclosure requirements, including (i) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and (ii) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. ASU 2018-14 is effective for annual periods ending after December 15, 2020. Early adoption of the amendments in this update is permitted. The Company is currently in the process of determining the impact the implementation of ASU 2018-14 will have on the Company’s financial statement note disclosures.

Income Taxes

In December 2019, the FASB issued Accounting Standard Update ASU No. 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes". This ASU simplifies the accounting for income taxes by removing certain exceptions previously included in the guidance. In addition, the ASU provides new guidance on accounting for specific taxes and minor codification improvements. ASU 2019-12 is effective for annual periods ending after December 15, 2020. Early adoption of the amendments in this update is permitted. The Company is currently in the process of determining the impact the implementation of ASU 2019-12 will have on the Company’s financial statement note disclosures.

Acquisitions and Divestitures

Note 3 – Acquisitions and Divestitures

In June 2018, Gentherm announced a new strategic plan. An important element of the strategy was the elimination of investments in non-core areas, including GPT and CSZ-IC.

Divestiture of CSZ-IC

On February 1, 2019, the Company completed the sale of CSZ-IC and the former Cincinnati Sub-Zero headquarters facility to Weiss Technik North America, Inc. for total cash proceeds of $47,500, including $2,500 of cash proceeds placed into an escrow account for a period of up to one year as partial security for the Company’s obligations under the sale agreement. The cash proceeds held in escrow are recorded as restricted cash within the consolidated condensed balance sheets. In connection with the sale, Gentherm entered into an operating lease agreement for a portion of the office and manufacturing building space purchased by Weiss Technik North America, Inc. The Company recognized a $4,970 pre-tax gain on the sale of CSZ-IC during the three months ended March 31, 2019, which is classified as Gain on sale of business within the consolidated condensed statements of income. In January 2020, claims were made against the cash proceeds held in the escrow account, which has been maintained in escrow following the expiration of the one-year escrow period. The Company is not able to estimate the possible loss, if any, of amounts held in escrow in connection with this matter.

Divestiture of GPT

During 2018, the Company determined that GPT met the held for sale criteria. During the three months ended March 31, 2019, the Company continued to assess the fair value of the GPT disposal group, less costs to sell, at each reporting period. As a result of these fair value measurements, the Company recorded impairment loss of $6,998 for the three months ended March 31, 2019. Additionally, during the three months ended March 31, 2019, the Company determined an equity investment met the held for sale criteria and recognized impairment loss of $3,486. On October 1, 2019, the Company completed the sale of GPT for a nominal amount.

Acquisition of Stihler

On April 1, 2019, Gentherm acquired Stihler for a purchase price of $15,476, net of cash acquired and including $653 of contingent consideration to be paid upon achievement of a milestone that must be completed by September 2020. In addition, the purchase agreement includes a contingent payment of $653 to be paid if the selling shareholder remains employed by Stihler through December 2020. This amount is being recognized as a component of selling, general and administrative expenses ratably over the service period. The results of operations of Stihler were reported within the Company’s Industrial segment from the date of acquisition. The acquisition was accounted for as a business combination. The purchase price and related allocation were finalized in the fourth quarter of 2019. The pro forma effect of the Stihler acquisition does not materially impact the Company’s reported results for any period presented, and as a result no pro forma financial statements are presented.

Restructuring And Related Activities [Abstract]

Restructuring

Note 4 – Restructuring

Manufacturing Footprint Rationalization

On September 23, 2019, the Company committed to a restructuring plan to improve the Company’s manufacturing productivity and rationalize its footprint. Under this plan, the Company will relocate and consolidate certain existing automotive manufacturing and, as a result, reduce the number of plants by two. On March 20, 2020, the Company announced the initial phase of this restructuring plan, which includes the consolidation of all North American electronics manufacturing to Celaya, Mexico. This will result in the closure of the Burlington, Canada facility, and the transfer of electronics manufacturing from Acuña, Mexico.

During the three months ended March 31, 2020, the Company recognized restructuring expense of $248 for employee separation costs and $242 for accelerated depreciation. The Company has recorded approximately $7,440 of restructuring expenses since the inception of this program.

The Company expects to incur total costs of between $20,000 and $24,000, of which between $17,000 and $21,000 are expected to be cash expenditures. The total expected costs include employee separation costs of between $9,000 and $11,000, capital expenditures of between $4,500 and $5,500 and non-cash expenses for accelerated depreciation and impairment of fixed assets of approximately $3,000. The Company also expects to incur other transition costs including recruiting, relocation, and machinery and equipment move and set up costs of between $3,500 and $4,500. The actions under this plan are expected to be substantially completed by the end of 2021. The actual timing, costs and savings of the plan may differ materially from the Company’s current expectations and estimates.

Other Restructuring Activities

As part of the Company’s continued efforts to optimize its cost structure, the Company has undertaken several discrete restructuring actions. During the three months ended March 31, 2020 and 2019, the Company recognized $3,054 and $395 of employee separation costs, respectively, and $222 and $4 of other related costs, respectively. In addition, during the three months ended March 31, 2019, the Company recognized $425 of asset impairment loss. These restructuring expenses were primarily associated with restructuring actions focused on the rotation of our manufacturing footprint to lower cost locations and the reduction of global overhead costs. These discrete restructuring actions are expected to approximate the total cumulative costs for those actions. The Company will continue to explore opportunities to improve its future profitability and competitiveness. These actions may result in the recognition of additional restructuring charges that could be material.

GPT and CSZ-IC

Costs associated with the divestiture process were classified as restructuring. During the three months ended March 31, 2019, the Company recognized $251 of employee separation costs, and $839 of other related costs, related to the marketing of GPT and CSZ-IC, which were classified as restructuring. The Company has recorded approximately $2,303 of restructuring expenses since inception of this program and it is considered complete.

Earnings Per Share [Abstract]

Earnings per Share

Note 5 – Earnings Per Share

Basic earnings per share are computed by dividing net income by the weighted average number of shares of Common Stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential shares of Common Stock outstanding during a period that do not have an anti-dilutive impact to the calculation. In computing the diluted earnings per share, the treasury stock method is used in determining the number of shares assumed to be issued from the exercise of Common Stock equivalents.

The following table illustrates earnings per share and the weighted average shares outstanding used in calculating basic and diluted earnings per share:

	Three Months Ended March 31,
	2020		2019
Net income	$	11,873	$	8,414

Basic weighted average shares of Common Stock outstanding		32,692,895		33,573,411
Dilutive effect of stock options, restricted stock awards and restricted stock units		176,254		159,924

Basic earnings per share	$	0.36	$	0.25
Diluted earnings per share	$	0.36	$	0.25

The following table represents Common Stock issuable upon the exercise of certain stock options that have been excluded from the diluted earnings calculation because the effect of their inclusion would be anti-dilutive.

Income Taxes

Note 8 – Income Taxes

At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to unusual or infrequent items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which those items occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs.

The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in respective jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. Jurisdictions with a projected loss for the year or a year-to-date loss for which no tax benefit or expense can be recognized due to a valuation allowance are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the composition and timing of actual earnings compared to annual projections. The estimates used to compute the provision or benefit for income taxes may change as new events occur, additional information is obtained or as our tax environment changes. To the extent that the expected annual effective income tax rate changes, the effect of the change on prior interim periods is included in the income tax provision in the period in which the change in estimate occurs.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into U.S. law. The CARES Act provides a stimulus and assistance package intended to address the impact of the COVID-19 pandemic, including tax relief and government loans, grants and investments. As permitted by the CARES Act, the Company expects to defer the payment of payroll taxes each quarter for the remainder of 2020 to be paid in the fourth quarters of 2021 and 2022.

A summary of the provision for income taxes and the corresponding effective tax rate for the three months ended March 31, 2020 and 2019, is shown below:

	Three Months Ended
	March 31,
	2020			2019
Income tax expense	$	5,406		$	6,895
Earnings before income tax	$	17,279		$	15,309
Effective tax rate		31.3	%		45.0	%

Income tax expense	$	5,406		$	6,895
Earnings before income tax excluding impairment loss	$	17,279		$	25,793
Effective tax rate excluding impairment loss		31.3	%		26.7	%

For the three months ended March 31, 2019, the Company recognized a loss of $10,484 related to a non-deductible impairment loss.

The annual effective tax rates differ from the U.S. statutory rate primarily due to foreign rates which differ from those in the U.S., U.S. taxes on foreign earnings, the realization of certain business tax credits, including research and development and foreign tax credits, and the applicable withholding taxes on the projected future repatriations of the earnings from the Company’s non-U.S. operations that are not considered permanently reinvested.

Amended Credit Agreement

As of December 31, 2018, the Company, together with certain direct and indirect subsidiaries, had a credit agreement (the “Credit Agreement”) which included a revolving credit note (“U.S. Revolving Note”) with a maximum borrowing capacity of $350,000.

On June 27, 2019, the Company entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”) with a consortium of lenders and Bank of America, N.A. as administrative agent. The Amended Credit Agreement amended and restated in its entirety the Credit Agreement. The outstanding principal and interest of the U.S. Revolving Note under the Credit Agreement continued and constitute obligations under the Amended Credit Agreement.

The Amended Credit Agreement increased the U.S. Revolving Note from $350,000 to $475,000 and extended the maturity from March 17, 2021 to June 27, 2024. Subject to specified conditions, the Company can increase the U.S. Revolving Note or incur secured term loans in an aggregate amount of $175,000. The Amended Credit Agreement also provides $15,000 availability for the issuance of letters of credit and a maximum of $40,000 for swing line borrowing. Any amount of the facility utilized for letters of credit or swing line loans outstanding will reduce the amount available under the Amended Credit Agreement. The Company had no outstanding letters of credit issued under the Amended Credit Agreement as of March 31, 2020 and December 31, 2019.

The U.S. borrowers and guarantors participating in the Amended Credit Agreement have entered into a related amended and restated pledge and security agreement. The amended and restated pledge and security agreement grants a security interest to the lenders in substantially all of the personal property of the Company and its U.S. subsidiaries designated as borrowers to secure their respective obligations under the Amended Credit Agreement, including the stock and membership interests of specified subsidiaries (limited to 66% of the stock in the case of certain non-U.S. subsidiaries). In addition to the security obligations, all obligations under the Amended Credit Agreement are unconditionally guaranteed by certain of the Company’s subsidiaries. The Amended Credit Agreement restricts, among other things, the amount of dividend payments the Company can make to shareholders.

The Amended Credit Agreement contains covenants, that, among other things, (i) prohibit or limit the ability of the borrowers and any material subsidiary to incur additional indebtedness, create liens, pay dividends, make certain types of investments (including acquisitions), enter into certain types of transactions with affiliates, prepay other indebtedness, sell assets, merge with other companies or enter into certain other transactions outside the ordinary course of business, and (ii) require that Gentherm maintain a minimum Consolidated Interest Coverage Ratio and Consolidated Leverage Ratio (based on consolidated EBITDA for the applicable trailing 12-month period as defined in the Amended Credit Agreement) as of the end of any fiscal quarter. The Amended Credit Agreement also contains customary events of default.

Under the Amended Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate Loans”) or Eurocurrency rate (“Eurocurrency Rate Loans”), plus a margin (“Applicable Rate”). The rate for Base Rate Loans is equal to the highest of the Federal Funds Rate (0.08% at March 31, 2020) plus 0.50%, Bank of America’s prime rate (3.25% at March 31, 2020), or the Eurocurrency rate plus 1.00%. The rate for Eurocurrency Rate Loans denominated in U.S. Dollars is equal to the London Interbank Offered Rate (0.99% at March 31, 2020). All loans denominated in a currency other than the U.S. Dollar must be Eurocurrency Rate Loans. Interest is payable at least quarterly.

The Applicable Rate varies based on the Consolidated Leverage Ratio reported by the Company. As long as the Company is not in default of the terms and conditions of the Amended Credit Agreement, the lowest and highest possible Applicable Rate is 1.25% and 2.25%, respectively, for Eurocurrency Rate Loans and 0.25% and 1.25%, respectively, for Base Rate Loans.

In March 2020, the Company increased its borrowings under the Amended Credit Agreement by $169,546 as a safeguard to increase its cash position and provide additional financial flexibility due to the COVID-19 pandemic. The proceeds will be used for working capital and for other general corporate purposes permitted by the Amended Credit Agreement. As of March 31, 2020, inclusive of the new borrowings, $225,417 was outstanding under the Amended Credit Agreement. Based upon consolidated EBITDA for the twelve months ended March 31, 2020, $226,743 remains available for additional borrowings under the Amended Credit Agreement subject to specified conditions that Gentherm currently satisfies.

DEG Vietnam Loan

The Company also has a fixed interest rate loan with the German Investment Corporation (“DEG”), a subsidiary of KfW Banking Group, a Germany government-owned development bank. The fixed interest rate senior loan agreement with DEG was used to finance the construction and set up of the Vietnam production facility (“DEG Vietnam Loan”). The DEG Vietnam Loan is subject to semi-annual principal payments that began November 2017 and will end May 2023. Under the terms of the DEG Vietnam Loan, the Company must maintain a minimum Equity Ratio and Enhanced Equity Ratio, as defined by the DEG Vietnam Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Vietnam Co. Ltd.

As of March 31, 2020, the Company was in compliance with the terms of the Amended Credit Agreement and DEG Vietnam Loan.

The scheduled principal maturities of our debt as of March 31, 2020 were as follows:

Derivative Financial Instruments

The Company is exposed to various market risks including, but not limited to, changes in foreign currency exchange rates, changes in interest rates and commodity price fluctuations. Market risks for changes in interest rates relate primarily to its debt obligations under the Amended Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in a location’s functional currency, foreign plant operations, intercompany indebtedness, intercompany investments and include exposures to the Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, Macedonian Denar, Ukrainian Hryvnia, Japanese Yen, Chinese Renminbi, Korean Won and Vietnamese Dong.

The Company regularly enters into derivative contracts with the objective of managing its financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. The maximum length of time over which the Company hedges its exposure to foreign currency exchange risks is one year. The Company had foreign currency derivative contracts with a notional value of $22,176 and $14,449 outstanding as of March 31, 2020 and December 31, 2019, respectively.

The Company does not enter into derivative financial instruments for speculative or trading purposes. The Company’s hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to accumulated other comprehensive loss in the consolidated condensed balance sheets. When the underlying hedge transaction is realized, the gain or loss included in accumulated other comprehensive loss is recorded in earnings in the consolidated condensed statements of income on the same line as the gain or loss on the hedged item attributable to the hedged risk. The Company records the ineffective portion of foreign currency hedging instruments, if any, to foreign currency gain (loss) in the consolidated condensed statements of income.

The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounts such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Note 14 – Fair Value Measurements

Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on one or more of the following three valuation techniques:

Market: This approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

Income: This approach uses valuation techniques to convert future amounts to a single present value amount based on current market expectations.

Cost: This approach is based on the amount that would be required to replace the service capacity of an asset (replacement cost).

The Company uses the following fair value hierarchy to measure fair value into three broad levels, which are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Inputs, other than quoted market prices included in Level 1, that are observable either directly or indirectly for the asset or liability.

Level 3: Unobservable inputs that are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Items Measured at Fair Value on a Recurring Basis

Except for derivative instruments (see Note 13), pension plan assets and a corporate owned life insurance policy, the Company had no material financial assets and liabilities that were carried at fair value at March 31, 2020 and December 31, 2019. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value.

Items Measured at Fair Value on a Nonrecurring Basis

The Company measures certain assets and liabilities at fair value on a non-recurring basis. As these nonrecurring fair value measurements are generally determined using unobservable inputs, these fair value measurements are classified within Level 3 of the fair value hierarchy. As of March 31, 2020 and December 31, 2019, there were no additional significant assets or liabilities measured at fair value on a non-recurring basis.

Items Not Carried at Fair Value

The Company uses an income valuation technique to measure the fair values of its debt instruments by converting amounts of future cash flows to a single present value amount using rates based on current market expectations (Level 2 inputs). As of March 31, 2020, and December 31, 2019, the carrying values of the indebtedness under the Company’s Amended Credit Agreement were not materially different than its estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 11). Discount rates used to measure the fair value of the DEG Vietnam Loan are based on quoted swap rates. As of March 31, 2020, the carrying value of the DEG Vietnam Loan was $8,750 as compared to an estimated fair value of $9,063. As of December 31, 2019, the carrying value of the DEG Vietnam Loan was $8,750 as compared to an estimated fair value of $8,785.

Commitments and Contingencies

Note 17 – Commitments and Contingencies

The Company may be subject to various legal actions and claims in the ordinary course of its business, including those arising out of breach of contracts, product warranties, product liability, intellectual property rights, environmental matters, regulatory matters and employment-related matters. The Company establishes accruals for matters which it believes that losses are probable and can be reasonably estimated. Although it is not possible to predict with certainty the outcome of these matters, the Company is of the opinion that the ultimate resolution of these matters will not have a material adverse effect on its consolidated condensed results of operations or financial position. Product liability and warranty reserves are recorded separately from legal reserves, as described below.

Product Liability and Warranty Matters

The Company accrues warranty obligations for products sold based on management estimates of future failure rates and current claim cost experience, with support from the sales, engineering, quality and legal functions. Using historical information available to the Company, including claims already filed by customers, the warranty accrual is adjusted quarterly to reflect management’s best estimate of future claims. The Company maintains liability insurance coverage at levels based on commercial norms and historical claims experience. The Company can provide no assurances that it will not experience material claims in the future or that it will not incur significant costs to defend such claims.

The following is a reconciliation of the changes in accrued warranty costs:

Subsequent Events

Note 18 – Subsequent Events

Subsequent to March 31, 2020, the impact of the COVID-19 pandemic on our business, results of operations and financial condition has materially worsened as compared to the first quarter of 2020. In particular, the Company significantly reduced production at its manufacturing facilities in response to COVID-19 related government mandates, reduced demand conditions and other operational drivers. This resulted in temporary, partial closures of several of the Company’s manufacturing facilities in the North America and Europe. Meanwhile, certain manufacturing facilities that were closed as of March 31, 2020 have re-opened. The extent of the further impact of the COVID-19 outbreak on the Company’s operational and financial performance, even after business operations resume, will depend on certain developments, including the duration and spread of the outbreak, the impact on its customers and suppliers and the range of governmental and community reactions to the pandemic, which are uncertain and cannot be fully predicted at this time.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated condensed financial statements included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to those rules and regulations. The information furnished in the consolidated condensed financial statements include all adjustments (consisting of only normal, recurring adjustments), considered necessary to present fairly the results of operations, financial position and cash flows of the Company. These financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The operating results for interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. In preparing these financial statements, management was required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and assumptions are based on our historical experience, the terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and suppliers and information available from other outside sources, as appropriate. These estimates and assumptions are subject to an inherent degree of uncertainty. We are not presently aware of any events or circumstances arising from the COVID-19 pandemic that would require us to update our estimates, judgments or revise the carrying value of our assets or liabilities. Our estimates may change, however, as new events occur and additional information is obtained. As a result, actual results may differ significantly from our estimates, and any such differences may be material to our financial statements.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Expected Credit Losses In June 2016, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2016-13 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and determined that the estimate of credit losses was not significantly impacted. Cloud Computing Arrangements That Are Service Contracts In August 2018, the FASB issued ASU 2018-15, “Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.” ASU 2018-15 requires implementation costs incurred by customers in cloud computing arrangements to be deferred and recognized over the term of the arrangement if those costs would be capitalized by the customer in a software licensing arrangement under the internal-use software guidance. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-15 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result. Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” ASU 2018-13 removes certain disclosure requirements, including (i) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, (ii) the policy for timing of transfer between levels, and (iii) the valuation processes for Level 3 fair value measurements. ASU 2018-13 also adds new disclosure requirements, including (i) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and (ii) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. ASU 2018-13 is effective for annual and interim periods beginning after December 15, 2019. The Company adopted ASU 2018-13 as of January 1, 2020 and there was no significant impact on its consolidated condensed financial statements and related disclosures as a result.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted Retirement Benefits In August 2018, the FASB issued ASU 2018-14, “Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans.” ASU 2018-14 removes certain disclosure requirements, including (i) the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year, and (ii) the amount and timing of plan assets expected to be returned to the employer. ASU 2018-14 also adds new disclosure requirements, including (i) the weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates and (ii) an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. ASU 2018-14 is effective for annual periods ending after December 15, 2020. Early adoption of the amendments in this update is permitted. The Company is currently in the process of determining the impact the implementation of ASU 2018-14 will have on the Company’s financial statement note disclosures.
