Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company	Note 1 – The Company Gentherm Incorporated is a global technology and industry leader in the design, development, and manufacturing of innovative thermal management technologies. 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 on the vehicles of nearly all major automotive manufacturers operating in North America, Europe and Asia. We operate in locations aligned with our major customers’ product strategies to provide locally enhanced design, integration and production capabilities and to identify future thermal technology product opportunities in both automotive and other markets. We concentrate our research on the development of new technologies and new applications from existing technologies to create product and market opportunities for a wide array of thermal management solutions. Sale of Cincinnati Sub-Zero Industrial Chamber Business (CSZ-IC) On February 1, 2019, as part of the Company’s Fit-for-Growth initiative to eliminate investments in non-core businesses, we completed the sale of the Cincinnati Sub-Zero industrial chamber business (“CSZ-IC”) and former Cincinnati Sub-Zero headquarters facility to Weiss Technik North America, Inc. for total cash proceeds of $47,500, including $2,500 of the cash proceeds were 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. 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 six-month period ended June 30, 2019. Restructuring As part of the Company’s continued efforts to optimize its cost structure, the Company has undertaken several discrete restructuring actions. During the three- and six-month periods ended June 30, 2019, the Company recognized $860 and $1,259 of one-time employee termination costs, respectively, and $349 and $349 of consultant costs, respectively. 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. During the three- and six-month periods ended June 30, 2018, the Company recognized $1,057 and $1,737 of one-time employee termination costs, respectively, and $37 and $1,499 of consultant costs, respectively. Advanced Research and Development Rationalization and Site Consolidation In June 2018, Gentherm completed a sale of its battery management systems division located in Irvine, California. A loss on the sale of $1,107 was recognized in restructuring expenses during the three- and six-month periods ended June 30, 2018. An additional loss of $425 was recognized during the six-month period ended June 30, 2019. During the three- and six-month periods ended June 30, 2018, Gentherm recognized $881 in one-time employee termination costs and $435 in contract termination costs associated with the closure of two leased facilities located in Azusa, California. Upon the adoption of ASU 2016-02, the remaining restructuring reserve related to the contract termination costs was released and an operating lease liability was established in its place The Company has recorded approximately $4,669 of restructuring expenses since inception of this program and it is considered substantially complete. GPT and CSZ-IC During 2018, Gentherm launched a program to actively market GPT and CSZ-IC and initiated all other actions required to complete the divestiture plan. During the three- and six-month periods ended June 30, 2019, the Company recognized $0 and $251 of one-time employee termination costs, respectively, and $22 and $861 of consultant costs, respectively. Note 1 – The Company – Continued During the three- and six-month periods ended June 30, 2018, the Company recognized $61 and $210 of one-time employee termination costs, respectively. The Company has recorded approximately $2,173 of restructuring expenses since inception of this program. Management cannot reasonably estimate the total amount of additional costs expected to be incurred. See Note 13 to our consolidated condensed financial statements for additional information regarding the assets and liabilities classified as held for sale. Restructuring Liability Restructuring liabilities totaling $649 and $2,547 as of June 30, 2019 and December 31, 2018, respectively, are classified as accrued liabilities on the consolidated condensed balance sheets. A reconciliation of the beginning and ending restructuring liability is as follows: One-Time Employee Termination Benefit Costs Contract Termination Costs Consulting Costs Asset Disposal Costs Total Six Months Ended June 30, 2019 Balance, beginning of period $ 2,079 $ 389 $ 79 $ — $ 2,547 Additions, charged to restructuring expenses 1,510 — 1,210 425 3,145 Payments (3,003 ) (139 ) (1,283 ) (425 ) (4,850 ) Reclassification to lease liability — (193 ) — — (193 ) Balance, end of period $ 586 $ 57 $ 6 $ — $ 649 Note 1 – The Company – Continued The cumulative amount of restructuring expenses incurred and recognized in the automotive and industrial reporting segments during the six-month period ended June 30, 2019 was $1,543 and $1,602, respectively.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies and Basis of Presentation	Note 2 – Summary of Significant Accounting Policies and Basis of Presentation Accounting Principles Our unaudited consolidated condensed financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the audited annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of our results of operations, financial position and cash flows have been included. The balance sheet as of December 31, 2018 was derived from audited annual consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. Certain reclassifications of prior year’s amounts have been made to conform with the current year’s presentation. Notably, $2,621 and $5,318 in customer relationship amortization was reclassified from product revenues to selling, general and administrative expenses for the three- and six-month periods ended June 30, 2018, respectively. Operating results for the six-month period ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These consolidated condensed financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018. Consolidation The consolidated condensed financial statements at June 30, 2019 and December 31, 2018 and for the six-month periods ended June 30, 2019 and 2018, reflect the consolidated financial position, the consolidated operating results and the consolidated cash flows of the Company. Investments in affiliates in which Gentherm would not have control, but would have the ability to exercise significant influence over operating and financial policies, would be accounted for under the equity method. All other equity investments are measured at cost, less impairment, with changes in fair value recognized in net income. Use of Estimates The presentation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates and assumptions. Note 2 – Summary of Significant Accounting Policies and Basis of Presentation – Continued Cash, cash equivalents and restricted cash The Company has cash that is legally restricted as to use or withdrawal. A reconciliation of cash and cash equivalents on the consolidated condensed balance sheets to cash, cash equivalents and restricted cash presented on the consolidated condensed statements of cash flows is as follows: Year June 30, 2019 June 30, 2018 December 31, Cash and cash equivalents presented in the consolidated condensed balance sheets $ 33,677 $ 39,620 $ 65,357 $ 103,172 Restricted cash 2,504 — — — Cash, cash equivalents and restricted cash presented in the consolidated condensed statements of cash flows $ 36,181 $ 39,620 $ 65,357 $ 103,172 Leases The Company determines whether a contractual arrangement is or contains a lease at inception. Leases that are operating in nature are recognized in operating lease right-of-use assets, accrued liabilities and non-current lease liabilities on our consolidated condensed balance sheets. While Gentherm is not currently party to any leases that qualify as financing leases, right-of-use assets and liabilities recognized from financing leases would be presented separately from the right-of-use assets and liabilities recognized from operating leases on our consolidated condensed balance sheet. Lease liabilities are measured initially at the present value of the sum of the future minimum rental payments at the commencement date of the lease. Lease payments that will vary in the future due to changes in facts and circumstances are excluded from the calculation of rental payments, unless those variable payments are based on an index or rate. Rental payments are discounted using an incremental borrowing rate based on the Company’s credit rating, determined on a fully collateralized loan basis from information available at commencement date, and the duration of the lease term (the “reference rate”). Judgement is used to assess the importance of risk factor inputs during the computation of the Company’s credit rating. For significant leases at foreign subsidiaries denominated in U.S. Dollars, a risk premium associated with the borrower subsidiary’s country is added to the reference rate. For significant leases at foreign subsidiaries denominated in a foreign currency, the U.S. Dollar risk free rate with a duration similar to that of the lease term is subtracted from the reference rate and a corresponding foreign currency risk free rate with a duration similar to that of the lease term is added to the reference rate. Judgement is used to determine whether foreign subsidiary leases are significant. Operating lease right-of-use assets are measured at the amount of the lease liability, adjusted for prepaid or accrued lease payments, lease incentive received, and initial direct costs incurred, as applicable. Periods covered by an option to extend the lease are initially included in the measurement of an operating lease right-of-use asset and lease liability only when it is reasonably certain we will exercise the option. Gentherm’s lease agreements do not contain residual value guarantees or impose restrictions or covenants on the Company. For all classes of underlying assets, the Company accounts for leases that contain separate lease and nonlease components as containing a single lease component. The Company does not recognize lease right-of-use assets and lease liabilities from leases with an original lease term of 12 months or less and, instead, recognizes rent payments on a straight-line basis over the lease term in the Company’s consolidated condensed statement of income. See Note 11 to our consolidated condensed financial statements for description of the changes made to our accounting policy for leases that resulted from the adoption of a new lease standard. Impairments of Goodwill and Other Intangible Assets Whenever events or changes in circumstances indicate that it is more likely than not that a reporting unit’s fair value is less than it’s carrying amount, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized. The fair value of a reporting unit is estimated by analyzing internal inputs (level 3) to calculate forward values and discounting those values to the present value. Note 2 – Summary of Significant Accounting Policies and Basis of Presentation – Continued There were no events or changes in circumstances which would indicate goodwill or other intangibles were impaired during the six-months ended June 30, 2019. A rolled forward reconciliation of goodwill from December 31, 2018 to June 30, 2019 is as follows: Six Months Ended June 30, 2019 Balance, beginning of period $ 55,311 Stihler acquisition 9,816 Currency impact (13) Balance, end of period $ 65,114 Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal group) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify as a completed sale within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less cost to sell. A loss resulting from this initial measurement is recognized in the period in which the held for sale criteria are met. The Company assesses the fair value of a disposal group, less cost to sell, each reporting period it remains classified as held for sale and reports any subsequent changes in the disposal group’s fair value less cost to sell (increase or decrease) as an adjustment to the disposal group’s carrying amount. Subsequent increases in fair value less cost to sell are recognized, but not in excess of the carrying amount of the disposal group at the time it was initially classified as held for sale. The Company reports assets and liabilities of the disposal group in the line items assets held for sale and liabilities held for sale in the consolidated condensed balance sheets as of each period the disposal group meets the criteria to be classified as held for sale. See Note 13 to our consolidated condensed financial statements for information about the assets and liabilities classified as held for sale.

Business Combinations [Abstract]
Business Acquisition	Note 3 – Business Acquisition On April 1, 2019 Gentherm acquired Stihler Electronic GmbH (“Stihler”), a leading developer and manufacturer of patient and blood temperature management systems, 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 will be recorded as a component of selling, general and administrative expenses ratably over the service period. The results of operations of Stihler are reported within the Company’s Industrial segment from the date of acquisition. During the three- and six-month periods ended June 30, 2019, the Company incurred acquisition-related costs of approximately $342 and $380, respectively. These amounts were recorded as incurred, within the Company's consolidated statements of income. The acquisition was accounted for as a business combination, with the total purchase price allocated on a preliminary basis using information available in the second quarter of 2019. The preliminary purchase price and related allocation to the acquired net assets of Stihler, based on their estimated fair values, is shown below: Purchase price, cash consideration, net of cash acquired $ 14,823 Purchase price, fair value of contingent consideration 653 Total purchase price, net of cash acquired 15,476 Accounts receivable $ 883 Inventory 1,698 Prepaid expenses and other assets 241 Operating lease right-of-use assets 263 Property and equipment 260 Other intangible assets 4,380 Goodwill 9,816 Assumed liabilities (2,065 ) Net assets acquired $ 15,476 Other intangible assets primarily include amounts recognized for the fair value of customer-related intangible assets, which will be amortized over their estimated useful lives of approximately 9 years. The estimated fair value of these assets was based on third-party valuations and management’s estimates, generally utilizing an income approach. Goodwill recognized in this transaction is primarily attributable to intangible assets that do not qualify for separate recognition. It is estimated that $2,524 of the goodwill recognized will be deductible for income tax purposes. The purchase price and related allocation are preliminary and could be revised for up to one year as a result of adjustments made to the purchase price, additional information obtained regarding liabilities assumed, including, but not limited to, contingent liabilities, revisions of provisional estimates of fair values, including, but not limited to, the completion of independent appraisals and valuations related to property, plant and equipment and intangible assets, and certain tax attributes. 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.

Earnings Per Share [Abstract]
Earnings per Share	Note 4 – Basic earnings per share are computed by dividing net income by the weighted average number of shares of stock outstanding during the period. The Company’s diluted earnings per share give effect to all potential 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 summarizes the Common Stock included in the basic and diluted shares, as disclosed on the face of the consolidated condensed statements of income: Three Months Six Months 2019 2018 2019 2018 Weighted average number of shares for calculation of basic EPS 33,440,764 36,523,742 33,508,479 36,560,193 Stock options, restricted stock awards and restricted stock units under equity incentive plans 132,844 143,257 142,638 103,033 Weighted average number of shares for calculation of diluted EPS 33,573,608 36,666,999 33,651,117 36,663,226 Note 4 – Earnings Per Share – Continued 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.

Segment Reporting [Abstract]
Segment Reporting	Note 5 – Segment Reporting Segment information is used by management for making strategic operating decisions for the Company. Management evaluates the performance of the Company’s segments based primarily on operating income or loss. The Company’s reportable segments are as follows: Automotive • Industrial – the combined operating results of GPT, Gentherm Medical and Gentherm’s advanced research and development division. We perform advanced research and development on thermal management systems, including those that utilize new proprietary comfort software algorithms, to enhance the efficiency and functionality of our automotive heating and cooling products. Unlike research and development that relates to a specific product application for a customer, advanced research and development activities affect products and technologies that are not currently generating product revenues. The segment includes government sponsored research projects. Reconciling Items – The tables below present segment information about the reported product revenues, depreciation and amortization and operating income (loss) of the Company for three- and six-month period ended June 30, 2019 and 2018. With the exception of goodwill, asset information by segment is not reported since the Company does not manage assets at a segment level. As of June 30, 2019, goodwill assigned to our Automotive and Industrial segments were $37,466 and $27,648, respectively.

Debt Disclosure [Abstract]
Debt	Note 6 – Debt 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 amends and restates 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 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 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 the amount of dividend payments the Company can make to shareholders. The Amended Credit Agreement requires the Company and its subsidiaries to comply with customary affirmative and negative covenants, and contain customary events of default. The Amended Credit Agreement also requires the Company to maintain a minimum Consolidated Interest Coverage Ratio and Consolidated Leverage Ratio, as defined in the agreement. 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 (2.40% at June 30, 2019) plus 0.50%, Bank of America’s prime rate (5.50% at June 30, 2019), or the Eurocurrency rate (0.00% at June 30, 2019) plus 1.00%. The rate for Eurocurrency Rate Loans denominated in U.S. Dollars is equal to the London Interbank Offered Rate (2.40% at June 30, 2019). 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 connection with the Amended Credit Agreement, the Company incurred debt issuance costs of $1,278 which have been capitalized and will be amortized into interest expense over the term of the credit facility. The Company also has two fixed interest rate loans with the German Investment Corporation (“DEG”), a subsidiary of KfW Banking Group, a Germany government-owned development bank. DEG China Loan The first DEG loan, a loan we used to fund capital investments in China (the “DEG China Loan”), is subject to semi-annual principal payments that began March, 2015 and will end September, 2019. Under the terms of the DEG China Loan, the Company must maintain a minimum Debt-to-Equity Ratio, Current Ratio and Debt Service Coverage Ratio, as defined by the DEG China Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Automotive Systems (China) Ltd. Note 6 – Debt – Continued DEG Vietnam Loan The Company’s second fixed interest rate 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. Undrawn borrowing capacity under the U.S. Revolving Note was $378,533 as of June 30, 2019. The following table summarizes the Company’s debt at June 30, 2019 and at December 31, 2018.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Note 7 – Derivative Financial Instruments We are exposed to market risk from changes in foreign currency exchange rates, short-term interest rates and price fluctuations of certain material commodities such as copper. Market risks for changes in interest rates relate primarily to our debt obligations under our 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 European Euro, Mexican Peso, Canadian Dollar, Hungarian Forint, Macedonian Denar, Ukrainian Hryvnia, Japanese Yen, Chinese Renminbi, Korean Won and Vietnamese Dong. Note 7 – Derivative Financial Instruments – Continued 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 we hedge our exposure to foreign currency exchange risks is one year. We had foreign currency derivative contracts with a notional value of $23,473 and $33,250 outstanding as of June 30, 2019 and December 31, 2018, respectively. The maximum length of time over which we hedge our exposure to price fluctuations in material commodities is two years. No commodity swap contracts were outstanding at June 30, 2019 or at December 31, 2018. We do not enter into derivative financial instruments for speculative or trading purposes. Our 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 balance sheet. When the underlying hedge transaction is realized, the gain or loss included in accumulated other comprehensive loss is recorded in earnings in the consolidated statements of income on the same line as the gain or loss on the hedged item attributable to the hedged risk. We record the ineffective portion of foreign currency hedging instruments, if any, to foreign currency gain (loss) in the consolidated statements of income. See Note 9 for the amount of unrealized loss associated with foreign currency derivatives previously reported in accumulated other comprehensive loss that was reclassified into earnings during 2019. Though we continuously monitor the hedging program, derivative positions and hedging strategies, foreign currency forward exchange agreements have not always been designated as hedging instruments for accounting purposes. 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. Information related to the recurring fair value measurement of derivative instruments in our consolidated condensed balance sheet as of June 30, 2019 is as follows: Asset Derivatives Liability Derivatives Net Asset/ Hedge Designation Fair Value Hierarchy Balance Sheet Fair Balance Sheet Fair Foreign currency derivatives Cash flow hedge Level 2 Current assets $ 1,155 Current liabilities $ — $ 1,155 Information relating to the effect of derivative instruments on our consolidated condensed statements of income is as follows: Location Three Months Ended June 30, 2019 Three Months Ended June 30, 2018 Six Months Ended June 30, 2019 Six Months Ended June 30, 2018 Foreign currency derivatives Product revenues $ 435 $ (524 ) $ 675 $ (605 ) Selling, general and administrative — 22 — 75 Other comprehensive income 297 (1,561 ) 1,063 551 Foreign currency (loss) gain (32 ) 10 (69) 47 Total foreign currency derivatives $ 700 $ (2,053 ) $ 1,669 $ 68 Commodity derivatives Cost of sales $ — $ — — $ 145 Other comprehensive income — — — (218 ) Total commodity derivatives $ — $ — $ $ — $ (73) We did not incur any hedge ineffectiveness during the three- and six-month periods ended June 30, 2019 and 2018.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8 – Fair Value Measurements The Company bases fair value on a price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used 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. 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. Except for derivative instruments (see Note 7), a corporate owned life insurance policy, and the held for sale disposal group (see Note 13), the Company had no material financial assets and liabilities that are carried at fair value at June 30, 2019 and December 31, 2018. The carrying amounts of financial instruments comprising cash and cash equivalents, restricted cash, accounts receivable and accounts payable approximate their fair values due to the relatively short maturity of such instruments. 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 June 30, 2019, and December 31, 2018, the carrying values of the indebtedness of the Company’s Amended Credit Agreement and Credit Agreement, respectively, were not materially different than their estimated fair values because the interest rates on variable rate debt approximated rates currently available to the Company (see Note 6). Discount rates used to measure the fair value of the DEG Vietnam Loan and DEG China Loan are based on quoted swap rates. As of June 30, 2019, the carrying values of the DEG Vietnam Loan and DEG China Loan were $10,000 and $455, respectively, as compared to an estimated fair value of $10,030 and $462, respectively. As of December 31, 2018, the carrying value of the DEG Vietnam Loan and DEG China Loan were $11,250 and $913, respectively, as compared to an estimated fair value of $11,100 and $900, respectively. Certain Company assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. Management’s estimates used to record impairment expense are inherently uncertain and may change in future periods.

New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements	Note 11 – New Accounting Pronouncements Recently Adopted Accounting Pronouncements Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842).” Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The update and related amendments require lessees to recognize on their balance sheet a liability to make payments and a right-of-use asset representing its right to use the underlying asset for the lease term. Leases are to be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of income. The requirement to recognize the rights and obligations resulting from leases as assets and liabilities by lessees increases transparency and comparability of lease transactions between organizations. New lessee disclosure requirements to provide information about the use of significant assumptions and judgements to identify and measure right-of-use assets and lease liabilities, enhance the representation of leasing transactions in financial statement note disclosures. We elected to adopt ASU 2016-02 and related amendments on its effective date, January 1, 2019, and recognized a cumulative-effect adjustment to the opening balance in retained earnings. Financial information has not been updated and disclosure under the new standard have not been provided to dates and periods before January 1, 2019. We elected the package of practical expedients provided in ASU 2016-02, which permits companies not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We elected the use-of-hindsight to determine whether lease terms include periods covered by the lessee’s option to extend or terminate a lease, whether to purchase the underlying asset at the end of the lease agreement, and in assessing impairment of operating lease right-of-use assets. Finally, we elected not to assess whether existing or expired land easements that were not previously accounted for as leases are or contain a lease. Land easements previously accounted for as leases are not eligible for this practical expedient. ASU 2016-02 did not have an impact on our consolidated condensed statements of income for the three- and six-month periods ended June 30, 2019, but had a significant impact on our consolidated condensed balance sheet as of June 30, 2019. Gentherm recognized $17,146 and $16,697 in new operating lease right-of-use assets and lease liabilities, respectively, on our consolidated condensed balance sheet as of the adoption date for the right to use lease assets, a difference of $449. Gentherm recognized $261 of this difference as an adjustment to the 2019 opening balance in retained earnings, net of tax effects totaling $114. The remaining $74 difference between operating lease right-of-use assets and lease liabilities for leases that existed as of the adoption date was recognized as a reduction to prepaid and other current assets. Note 11 – New Accounting Pronouncements – Continued ASU 2016-02 provides lessees with practical expedients applicable on an ongoing basis, beyond the period of adoption. First, lessees may elect, by class of underlying asset, to not recognize operating lease right-of-use assets and lease liabilities from leases with an original lease term of 12 months or less. For entities that elect this accounting policy for short term leases, lease payments from short term leases are recognized on a straight-line basis over the lease term in the Company’s consolidated condensed statement of income. Second, lessees may elect, by class of underlying assets, to not separate nonlease components that are associated with lease components in a lease agreement and instead to account for them together as a single lease component. The Company elected these ongoing practical expedients and applies them to all classes of leased assets. Recently Issued Accounting Pronouncements Not Yet Adopted Expected Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. Financial assets measured at amortized cost basis are to be reported on the balance sheet at the initial acquisition amount less principal repayments, amortization of any discounts or premiums, foreign exchange difference, and impairment losses. The valuation account allowance for credit losses is deducted from the amortized cost basis to present the net carrying value at the amount expected to be collected on the financial asset. Currently, entities with financial assets within the scope of this update use the incurred loss model to measure and recognize credit losses. Under the incurred loss model, past events and current conditions are inputs to measure credit losses and recognize them in the period the likelihood of loss is probable. The expected loss model broadens the amount and type of information, including forecasted information, entities must consider developing its expected credit loss estimate for financial assets. The amendments in this update do not specify a method for measuring expected credit losses and it is anticipated that entities will leverage current systems and methods for recording the allowance for credit losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. Early adoption of the amendments in this update is permitted, including adoption in any interim period for which financial statements have not yet been issued. The amendments in this update should be applied using a modified-retrospective approach and a cumulative-effect adjustment to retained earnings recognized as of the beginning of the first reporting period in which the guidance is effective. We are currently in the process of determining the impact implementation of ASU 2016-13 will have on the Company’s financial statements and note disclosures. 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 provides guidance on when costs incurred to implement a hosting arrangement that is a service contract are and are not capitalized, aligning with the guidance for capitalizing implementation costs incurred to develop or obtain internal-use software. Entities must first determine the project stage of the implementation activity; depending on their nature, costs for implementation activities in the application development stage are capitalized and costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. Capitalized implementation costs should be amortized over the term of the hosting arrangement on a straight-line basis and presented in the same line items in the statement of income as the expense for fees for the associated hosting arrangements. Similarly, capitalized implementation costs should be presented in same line item in the balance sheet as prepaid fees for the associated hosting arrangement and cash flows from capitalized implementation costs should be classified in the same manner as cash flows for the fees for the associated hosting arrangement. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019. Early adoption of the amendments in this update is permitted, including adoption in any interim period for which financial statements have not yet been issued. ASU 2018-15 permits two methods of adoption: prospectively to costs for activities performed on or after the date the entity first applies the content from the update, or retrospectively to all periods presented. We are currently in the process of determining the impact implementation of ASU 2018-15 will have on the Company’s financial statements and note disclosures. Note 11 – New Accounting Pronouncements – Continued 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.” The amendments in ASU 2018-14 were developed using the concepts incorporated in the FASB’s Concepts Statement, Conceptual Framework for Financial Reporting – Chapter 8: Notes to Financial Statements, 1) The amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. 2) The amount and timing of plan assets expected to be returned to the employer. The following disclosure requirements were added to Subtopic 715-20: 1) The weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates. 2) 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 are permitted. Entities should apply the amendments in this update on a retrospective basis to all periods presented. We are currently in the process of determining the impact implementation of ASU 2018-14 will have on the Company’s financial statement note disclosures. 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.” The amendments in ASU 2018-13 were developed using the concepts incorporated in the FASBs Concepts Statement, Conceptual Framework for Financial Reporting – Chapter 8: Notes to Financial Statements, 1) The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. 2) The policy for timing of transfer between levels. 3) The valuation processes for Level 3 fair value measurements. The following disclosure requirements were added to Topic 820: 1) 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. 2) 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. Early adoption of disclosures that are removed is permitted, but adoption is delayed for the new additional disclosures until their effective date. The amendments in ASU 2018-13 that provide for new additional disclosure should be applied on a prospective basis, while all other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently in the process of determining the impact implementation of ASU 2018-13 will have on the Company’s financial statement note disclosures.

Leases [Abstract]
Leases	Note 12 – Leases The Company has operating leases for office, manufacturing and research and development facilities, as well as land leases for certain manufacturing facilities that are accounted for as operating leases. We also have operating leases for office equipment and automobiles. Excluding land leases, our leases have remaining lease terms ranging from 1 year to 7 years and may include options to extend the lease for an additional term equal to the original term of the lease. Land leases have remaining lease terms that range from 29 to 44 years and some which specify that the end of the lease term is at the discretion of the lessee. We do not have lease arrangements with related parties. Information about Gentherm’s total lease costs for the six-month period ended June 30, 2019 is as follows: Six Months Ended June 30, 2019 Lease cost Operating lease cost $ 2,903 Short-term lease cost 1,885 Sublease income (52 ) Total lease cost $ 4,736 Supplemental Cash Flow Information Gain on sale and leaseback transactions, net $ 207 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 2,966 Right-of-use lease assets obtained in exchange for lease obligations: Operating leases $ 3,004 Weighted Average Remaining Lease Term Operating leases 4.7 years Weighted Average Discount Rate Operating leases 5.4 % A summary of operating leases as of June 30, 2019, under all non-cancellable operating leases with terms exceeding one year is as follows: 2019 (excluding the six-month period ended June 30, 2019) $ 2,755 2020 4,489 2021 2,555 2022 1,490 2023 790 2024 or later 2,609 Total future minimum lease payments 14,688 Less imputed interest (1,916 ) Total 12,772

Discontinued Operations And Disposal Groups [Abstract]
Assets and Liabilities Held for Sale	Note 13 – Assets and Liabilities Held for Sale During 2018, the Company determined that GPT met the held for sale criteria and recognized $2,190 in impairment loss. During 2019, the Company continued to assess the fair value of its GPT disposal group, less costs to sell, at each reporting period. As a result of these fair value measurements, the Company recorded additional impairment losses of $9,885 and $16,883 for the three- and six-month periods ended June 30, 2019, respectively. Additionally, during the first quarter of 2019, the Company determined that an equity investment met the held for sale criteria and recognized impairment losses of $1,000 and $4,486 for the three- and six-month periods ended June 30, 2019, respectively. See note 2 for information about the Company’s held for sale accounting policy, including a description of the criteria necessary for a disposal group to qualify for classification as held for sale. GPT did not meet the criteria to be classified as a discontinued operation. The assets and liabilities of the disposal group classified as held for sale as of June 30, 2019 are as follows: Accounts receivable, net $ 1,808 Inventory, net 5,499 Prepaid expenses and other assets 268 Operating lease right-of-use assets 4,118 Investment — Property and equipment, net 7,440 Other intangible assets, net 1,082 Deferred income tax assets 4,572 Impairment loss (18,073 ) Total assets held for sale $ 6,714 Accounts payable $ 405 Accrued liabilities 2,192 Operating lease liabilities 4,117 Total liabilities held for sale $ 6,714 The equity investment described above, does not have a readily determinable fair value and is measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer. The fair value of the GPT disposal group was measured based on observable inputs other than Level 1 prices. Management’s estimates used to record impairment expense are inherently uncertain and may change in future periods.

Summary of Significant Accounting Policies and Basis of Presentation (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Accounting Principles	Accounting Principles Our unaudited consolidated condensed financial statements and accompanying notes have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and note disclosures normally included in the audited annual consolidated financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted pursuant to those rules and regulations. In the opinion of management, all adjustments, consisting of normal recurring items, considered necessary for a fair presentation of our results of operations, financial position and cash flows have been included. The balance sheet as of December 31, 2018 was derived from audited annual consolidated financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. Certain reclassifications of prior year’s amounts have been made to conform with the current year’s presentation. Notably, $2,621 and $5,318 in customer relationship amortization was reclassified from product revenues to selling, general and administrative expenses for the three- and six-month periods ended June 30, 2018, respectively. Operating results for the six-month period ended June 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. These consolidated condensed financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2018.
Consolidation	Consolidation The consolidated condensed financial statements at June 30, 2019 and December 31, 2018 and for the six-month periods ended June 30, 2019 and 2018, reflect the consolidated financial position, the consolidated operating results and the consolidated cash flows of the Company. Investments in affiliates in which Gentherm would not have control, but would have the ability to exercise significant influence over operating and financial policies, would be accounted for under the equity method. All other equity investments are measured at cost, less impairment, with changes in fair value recognized in net income.
Use of Estimates	Use of Estimates The presentation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from those estimates and assumptions.
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash The Company has cash that is legally restricted as to use or withdrawal. A reconciliation of cash and cash equivalents on the consolidated condensed balance sheets to cash, cash equivalents and restricted cash presented on the consolidated condensed statements of cash flows is as follows: Year June 30, 2019 June 30, 2018 December 31, Cash and cash equivalents presented in the consolidated condensed balance sheets $ 33,677 $ 39,620 $ 65,357 $ 103,172 Restricted cash 2,504 — — — Cash, cash equivalents and restricted cash presented in the consolidated condensed statements of cash flows $ 36,181 $ 39,620 $ 65,357 $ 103,172
Leases	Leases The Company determines whether a contractual arrangement is or contains a lease at inception. Leases that are operating in nature are recognized in operating lease right-of-use assets, accrued liabilities and non-current lease liabilities on our consolidated condensed balance sheets. While Gentherm is not currently party to any leases that qualify as financing leases, right-of-use assets and liabilities recognized from financing leases would be presented separately from the right-of-use assets and liabilities recognized from operating leases on our consolidated condensed balance sheet. Lease liabilities are measured initially at the present value of the sum of the future minimum rental payments at the commencement date of the lease. Lease payments that will vary in the future due to changes in facts and circumstances are excluded from the calculation of rental payments, unless those variable payments are based on an index or rate. Rental payments are discounted using an incremental borrowing rate based on the Company’s credit rating, determined on a fully collateralized loan basis from information available at commencement date, and the duration of the lease term (the “reference rate”). Judgement is used to assess the importance of risk factor inputs during the computation of the Company’s credit rating. For significant leases at foreign subsidiaries denominated in U.S. Dollars, a risk premium associated with the borrower subsidiary’s country is added to the reference rate. For significant leases at foreign subsidiaries denominated in a foreign currency, the U.S. Dollar risk free rate with a duration similar to that of the lease term is subtracted from the reference rate and a corresponding foreign currency risk free rate with a duration similar to that of the lease term is added to the reference rate. Judgement is used to determine whether foreign subsidiary leases are significant. Operating lease right-of-use assets are measured at the amount of the lease liability, adjusted for prepaid or accrued lease payments, lease incentive received, and initial direct costs incurred, as applicable. Periods covered by an option to extend the lease are initially included in the measurement of an operating lease right-of-use asset and lease liability only when it is reasonably certain we will exercise the option. Gentherm’s lease agreements do not contain residual value guarantees or impose restrictions or covenants on the Company. For all classes of underlying assets, the Company accounts for leases that contain separate lease and nonlease components as containing a single lease component. The Company does not recognize lease right-of-use assets and lease liabilities from leases with an original lease term of 12 months or less and, instead, recognizes rent payments on a straight-line basis over the lease term in the Company’s consolidated condensed statement of income. See Note 11 to our consolidated condensed financial statements for description of the changes made to our accounting policy for leases that resulted from the adoption of a new lease standard.
Impairments of Goodwill and Other Intangible Assets	Impairments of Goodwill and Other Intangible Assets Whenever events or changes in circumstances indicate that it is more likely than not that a reporting unit’s fair value is less than it’s carrying amount, the Company then compares the fair value of the reporting unit to the related net book value. If the net book value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized. The fair value of a reporting unit is estimated by analyzing internal inputs (level 3) to calculate forward values and discounting those values to the present value. Note 2 – Summary of Significant Accounting Policies and Basis of Presentation – Continued There were no events or changes in circumstances which would indicate goodwill or other intangibles were impaired during the six-months ended June 30, 2019. A rolled forward reconciliation of goodwill from December 31, 2018 to June 30, 2019 is as follows: Six Months Ended June 30, 2019 Balance, beginning of period $ 55,311 Stihler acquisition 9,816 Currency impact (13) Balance, end of period $ 65,114
Assets and Liabilities Held for Sale	Assets and Liabilities Held for Sale The Company classifies assets and liabilities (disposal group) to be sold as held for sale in the period in which all of the following criteria are met: management, having the authority to approve the action, commits to a plan to sell the disposal group; the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; an active program to locate a buyer and other actions required to complete the plan to sell the disposal group have been initiated; the sale of the disposal group is probable, and transfer of the disposal group is expected to qualify as a completed sale within one year, except if events or circumstances beyond the Company’s control extend the period of time required to sell the disposal group beyond one year; the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The Company initially measures a disposal group that is classified as held for sale at the lower of its carrying value or fair value less cost to sell. A loss resulting from this initial measurement is recognized in the period in which the held for sale criteria are met. The Company assesses the fair value of a disposal group, less cost to sell, each reporting period it remains classified as held for sale and reports any subsequent changes in the disposal group’s fair value less cost to sell (increase or decrease) as an adjustment to the disposal group’s carrying amount. Subsequent increases in fair value less cost to sell are recognized, but not in excess of the carrying amount of the disposal group at the time it was initially classified as held for sale. The Company reports assets and liabilities of the disposal group in the line items assets held for sale and liabilities held for sale in the consolidated condensed balance sheets as of each period the disposal group meets the criteria to be classified as held for sale. See Note 13 to our consolidated condensed financial statements for information about the assets and liabilities classified as held for sale.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standard Update (“ASU”) 2016-02, “Leases (Topic 842).” Topic 842 was subsequently amended by ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; and ASU 2018-11, Targeted Improvements. The update and related amendments require lessees to recognize on their balance sheet a liability to make payments and a right-of-use asset representing its right to use the underlying asset for the lease term. Leases are to be classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of income. The requirement to recognize the rights and obligations resulting from leases as assets and liabilities by lessees increases transparency and comparability of lease transactions between organizations. New lessee disclosure requirements to provide information about the use of significant assumptions and judgements to identify and measure right-of-use assets and lease liabilities, enhance the representation of leasing transactions in financial statement note disclosures. We elected to adopt ASU 2016-02 and related amendments on its effective date, January 1, 2019, and recognized a cumulative-effect adjustment to the opening balance in retained earnings. Financial information has not been updated and disclosure under the new standard have not been provided to dates and periods before January 1, 2019. We elected the package of practical expedients provided in ASU 2016-02, which permits companies not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs. We elected the use-of-hindsight to determine whether lease terms include periods covered by the lessee’s option to extend or terminate a lease, whether to purchase the underlying asset at the end of the lease agreement, and in assessing impairment of operating lease right-of-use assets. Finally, we elected not to assess whether existing or expired land easements that were not previously accounted for as leases are or contain a lease. Land easements previously accounted for as leases are not eligible for this practical expedient. ASU 2016-02 did not have an impact on our consolidated condensed statements of income for the three- and six-month periods ended June 30, 2019, but had a significant impact on our consolidated condensed balance sheet as of June 30, 2019. Gentherm recognized $17,146 and $16,697 in new operating lease right-of-use assets and lease liabilities, respectively, on our consolidated condensed balance sheet as of the adoption date for the right to use lease assets, a difference of $449. Gentherm recognized $261 of this difference as an adjustment to the 2019 opening balance in retained earnings, net of tax effects totaling $114. The remaining $74 difference between operating lease right-of-use assets and lease liabilities for leases that existed as of the adoption date was recognized as a reduction to prepaid and other current assets. Note 11 – New Accounting Pronouncements – Continued ASU 2016-02 provides lessees with practical expedients applicable on an ongoing basis, beyond the period of adoption. First, lessees may elect, by class of underlying asset, to not recognize operating lease right-of-use assets and lease liabilities from leases with an original lease term of 12 months or less. For entities that elect this accounting policy for short term leases, lease payments from short term leases are recognized on a straight-line basis over the lease term in the Company’s consolidated condensed statement of income. Second, lessees may elect, by class of underlying assets, to not separate nonlease components that are associated with lease components in a lease agreement and instead to account for them together as a single lease component. The Company elected these ongoing practical expedients and applies them to all classes of leased assets.
Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Issued Accounting Pronouncements Not Yet Adopted Expected Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. Financial assets measured at amortized cost basis are to be reported on the balance sheet at the initial acquisition amount less principal repayments, amortization of any discounts or premiums, foreign exchange difference, and impairment losses. The valuation account allowance for credit losses is deducted from the amortized cost basis to present the net carrying value at the amount expected to be collected on the financial asset. Currently, entities with financial assets within the scope of this update use the incurred loss model to measure and recognize credit losses. Under the incurred loss model, past events and current conditions are inputs to measure credit losses and recognize them in the period the likelihood of loss is probable. The expected loss model broadens the amount and type of information, including forecasted information, entities must consider developing its expected credit loss estimate for financial assets. The amendments in this update do not specify a method for measuring expected credit losses and it is anticipated that entities will leverage current systems and methods for recording the allowance for credit losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. Early adoption of the amendments in this update is permitted, including adoption in any interim period for which financial statements have not yet been issued. The amendments in this update should be applied using a modified-retrospective approach and a cumulative-effect adjustment to retained earnings recognized as of the beginning of the first reporting period in which the guidance is effective. We are currently in the process of determining the impact implementation of ASU 2016-13 will have on the Company’s financial statements and note disclosures. 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 provides guidance on when costs incurred to implement a hosting arrangement that is a service contract are and are not capitalized, aligning with the guidance for capitalizing implementation costs incurred to develop or obtain internal-use software. Entities must first determine the project stage of the implementation activity; depending on their nature, costs for implementation activities in the application development stage are capitalized and costs incurred during the preliminary project and post-implementation stages are expensed as the activities are performed. Capitalized implementation costs should be amortized over the term of the hosting arrangement on a straight-line basis and presented in the same line items in the statement of income as the expense for fees for the associated hosting arrangements. Similarly, capitalized implementation costs should be presented in same line item in the balance sheet as prepaid fees for the associated hosting arrangement and cash flows from capitalized implementation costs should be classified in the same manner as cash flows for the fees for the associated hosting arrangement. ASU 2018-15 is effective for annual and interim periods beginning after December 15, 2019. Early adoption of the amendments in this update is permitted, including adoption in any interim period for which financial statements have not yet been issued. ASU 2018-15 permits two methods of adoption: prospectively to costs for activities performed on or after the date the entity first applies the content from the update, or retrospectively to all periods presented. We are currently in the process of determining the impact implementation of ASU 2018-15 will have on the Company’s financial statements and note disclosures. Note 11 – New Accounting Pronouncements – Continued 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.” The amendments in ASU 2018-14 were developed using the concepts incorporated in the FASB’s Concepts Statement, Conceptual Framework for Financial Reporting – Chapter 8: Notes to Financial Statements, 1) The amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year. 2) The amount and timing of plan assets expected to be returned to the employer. The following disclosure requirements were added to Subtopic 715-20: 1) The weighted-average interest crediting rates for cash balance plans and other plans with promised interest crediting rates. 2) 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 are permitted. Entities should apply the amendments in this update on a retrospective basis to all periods presented. We are currently in the process of determining the impact implementation of ASU 2018-14 will have on the Company’s financial statement note disclosures. 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.” The amendments in ASU 2018-13 were developed using the concepts incorporated in the FASBs Concepts Statement, Conceptual Framework for Financial Reporting – Chapter 8: Notes to Financial Statements, 1) The amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. 2) The policy for timing of transfer between levels. 3) The valuation processes for Level 3 fair value measurements. The following disclosure requirements were added to Topic 820: 1) 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. 2) 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. Early adoption of disclosures that are removed is permitted, but adoption is delayed for the new additional disclosures until their effective date. The amendments in ASU 2018-13 that provide for new additional disclosure should be applied on a prospective basis, while all other amendments should be applied retrospectively to all periods presented upon their effective date. We are currently in the process of determining the impact implementation of ASU 2018-13 will have on the Company’s financial statement note disclosures.
