Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General Nature of operations and basis of presentation. Horizon Global Corporation (“Horizon,” “Horizon Global,” “we,” or the “Company”) is a global designer, manufacturer and distributor of a wide variety of high quality, custom-engineered towing, trailering, cargo management and other related accessories. These products are designed to support original equipment manufacturers (“OEMs”) and original equipment servicers (“OESs”) (collectively, “OEs”), aftermarket and retail customers within the agricultural, automotive, construction, horse/livestock, industrial, marine, military, recreational, trailer and utility markets. The Company groups its business into operating segments by the region in which sales and manufacturing efforts are focused. The Company’s operating segments are Horizon Americas , Horizon Europe-Africa , and Horizon Asia-Pacific . See Note 16 , “ Segment Information ,” for further information on each of the Company’s operating segments. The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial information and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 . Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States (“U.S. GAAP”) for complete financial statements. It is management’s opinion that these financial statements contain all adjustments, including adjustments of a normal and recurring nature, necessary for a fair presentation of financial position and results of operations. Results of operations for interim periods are not necessarily indicative of results for the full year. Corporate history . On June 30, 2015, Horizon became an independent company as a result of the distribution by TriMas Corporation (“TriMas” or “former parent”) of 100 percent of the outstanding common shares of Horizon Global to TriMas shareholders (the “Spin-off”). Each TriMas shareholder of record as of the close of business on June 25, 2015 (the “Record Date”) received two Horizon Global common shares for every five TriMas common shares held as of the Record Date. The Spin-off was completed on June 30, 2015 and was structured to be tax-free to both TriMas and Horizon Global shareholders. On July 1, 2015, Horizon Global common shares began regular trading on the New York Stock Exchange under the ticker symbol “HZN”.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting pronouncements recently adopted In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, “Compensation - Stock Compensation (Topic 718)” (“ASU 2018-07”). ASU 2018-07 expands the scope of Accounting Standard Codification (“ASC”) 718 to include all share-based payment arrangements related to the acquisition of goods and services from both non-employees and employees. ASU 2018-07 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 with early adoption permitted. The Company adopted ASU 2018-07 on January 1, 2019, and there was no impact on the Company’s condensed consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also modifies the accounting for components excluded from the assessment of hedge effectiveness, eases documentation and assessment requirements and modifies certain disclosure requirements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted and should be applied on a modified retrospective basis. The Company adopted ASU 2017-12 on January 1, 2019, and there was no impact on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which supersedes the lease requirements in “Leases (Topic 840).” The objective of this update is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. Under this guidance, lessees are required to recognize on the balance sheet a lease liability and a right-of-use (“ROU”) asset for all leases, with the exception of short-term leases with terms of twelve months or less. The lease liability represents the lessee’s obligation to make lease payments arising from a lease and will be measured as the present value of the lease payments. The ROU asset represents the lessee’s right to use a specified asset for the lease term, and will be measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the lessee’s initial direct costs. The Company has elected the package of practical expedients, excluding the lease term hindsight, as permitted by the transition guidance. The Company has made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases will be expensed over the lease term. The Company adopted the standard on January 1, 2019, by applying the modified retrospective method without restatement of comparative periods' financial information, as permitted by the transition guidance. The standard had a material impact on the Company’s condensed consolidated balance sheets, but did not have an impact on its condensed consolidated statements of operations and cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the Company’s accounting for finance leases remained substantially unchanged. See Note 11 “ Leases, ” for the impact of the adoption which resulted in the recognition of ROU assets and corresponding lease liabilities.

The ABL Facility consists of (i) a U.S. sub-facility, in an aggregate principal amount of up to $85.0 million (subject to availability under a U.S.-specific borrowing base) (the “U.S. Facility”), (ii) a Canadian sub-facility, in an aggregate principal amount of up to $2.0 million (subject to availability under a Canadian-specific borrowing base) (the “Canadian Facility”), and (iii) a U.K. sub-facility in an aggregate principal amount of up to $3.0 million (subject to availability under a U.K.-specific borrowing base) (the “U.K. Facility”). The ABL Facility also includes a $20.0 million U.S. letter of credit sub-facility. All facilities under the ABL Facility mature on June 30, 2020. The Company incurred debt issuance costs of approximately $1.4 million in connection with the March 2019 amendment of the ABL Facility. These debt issuance costs will be amortized into interest expense over the contractual term of the loan. The Company recognized $0.1 million of amortization of debt issuance costs for the three months ended March 31, 2019 , and 2018 , respectively, which are included in the accompanying condensed consolidated statements of operations. There were $1.9 million and $0.8 million of unamortized debt issuance costs included in other assets in the accompanying condensed consolidated balance sheets as of March 31, 2019 and December 31, 2018 , respectively. There were $45.0 million and $61.6 million outstanding under the ABL Facility as of March 31, 2019 and December 31, 2018 , respectively, with a weighted average interest rate of 6.3% and 4.4% , respectively. Total letters of credit issued under the ABL Facility at March 31, 2019 and December 31, 2018 were $5.0 million and $3.4 million , respectively. The Company had $29.0 million and $10.3 million in availability under the ABL Facility as of March 31, 2019 and December 31, 2018 , respectively. First Lien Term Loan (formerly “Term Loan”) In February 2019, the Company amended and restated the existing Term Loan Agreement to permit the Company to enter into the Senior Term Loan Agreement and tightened certain indebtedness, asset sale, investment and restricted payment baskets. In March 2019, the Company amended the existing Term Loan Agreement (“Sixth Term Amendment”) (the “First Lien Term Loan Agreement”) to permit the Company to enter into the Second Lien Term Loan Agreement; amend certain financial covenants to provide for relief based on the Company’s 2018 and 2019 budget, and make certain other affirmative and negative covenants more restrictive. Pursuant to the Sixth Term Amendment, the prior net leverage covenant ratio was eliminated and replaced with a first lien leverage covenant starting with the 12-month period ending September 2019 as follows: September 30, 2019: 8.25 :1.00 December 31, 2019: 6.25 :1.00 March 31, 2020: 5.50 :1.00 June 30, 2020: 5.00 :1.00 September 30, 2020 and each fiscal quarter ending thereafter: 4.75 :1.00 The Sixth Term Amendment also added a fixed charge coverage covenant starting with fiscal quarter ending March 31, 2020, a minimum liquidity covenant of $15.0 million starting March 31, 2019, and a maximum capital expenditure covenant of $15.0 million for 2019 and $25.0 million annually thereafter. The interest rate on the First Lien Term Loan Agreement is also amended to add 3.0% paid-in-kind interest in addition to the existing cash pay interest. Debt issuance costs of approximately $5.6 million were incurred in connection with the Sixth Term Amendment. In accordance with ASC 470-50, “Modifications and Extinguishments,” the Company recorded approximately $0.7 million of issuance costs in selling, general and administrative expense in the accompanying condensed consolidated statements of operations during the three months ended March 31, 2019 and capitalized approximately $4.9 million of debt issuance costs that will be amortized into interest expense over the contractual term of the loan using the effective interest method. The Company also recorded approximately $3.0 million of unamortized debt issuance costs to interest expense for three months ended March 31, 2019 , due to the extinguishment of debt for certain lenders in the loan syndicate. The Company recognized approximately $0.8 million and $0.4 million of amortization of debt issuance and discount cost for the three months ended March 31, 2019 and 2018 , respectively, which is included in the accompanying condensed consolidated statements of operations. The Company had an aggregate principal amount outstanding of $187.9 million and $190.5 million as of March 31, 2019 and December 31, 2018 , respectively, under the First Lien Term Loan bearing interest at 8.5% and 8.8% , respectively. All of the indebtedness under the First Lien Term Loan is and will be guaranteed by the Company’s existing and future material domestic subsidiaries and is and will be secured by substantially all of the assets of the Company and such guarantors. Senior Term Loan Agreement In February 2019, the Company entered into a Credit Agreement (the “Senior Term Loan Agreement”) with Cortland Capital Markets Services LLC, as administrative agent and collateral agent, and the lenders party thereto. The Senior Term Loan Agreement provided for a short-term loan facility in the aggregate principal amount of $10.0 million , all of which was borrowed by the Company. Certain of the lenders under the Company’s First Lien Term Loan Agreement were the lenders under the Senior Term Loan Agreement. The Senior Term Loan Agreement required the Company to obtain additional financing in amounts and on terms acceptable to the lenders. The Senior Term Loan Agreement was repaid on March 15, 2019, in conjunction with the additional financing further detailed below. The Company incurred debt issuance costs of approximately $0.5 million in connection with the Senior Term Loan Agreement, which were recorded to selling, general and administrative expense within the accompanying condensed consolidated statements of operations. Second Lien Term Loan Agreement In March 2019, the Company entered into a Credit Agreement (the “Second Lien Term Loan Agreement”) with Cortland Capital Markets Services LLC, as administrative agent and collateral agent, and Corre Partners Management L.L.C., as representative of the lenders, and the lenders party thereto. The Second Lien Term Loan Agreement provides for a term loan facility in the aggregate principal amount of $51.0 million and matures on September 30, 2021. The interest on the Second Lien Term Loan may be paid, at the Company’s election, in cash, at the customary eurocurrency rate plus a margin of 10.50% per annum, or in-kind, at the customary eurocurrency rate plus a margin of 11.50% . The Second Lien Term Loan Agreement is secured by a second lien on substantially the same collateral as the First Lien Term Loan and is subject to various affirmative and negative covenants including a secured net leverage ratio tested quarterly, commencing with the fiscal quarter ending on December 31, 2019, which shall not exceed (x) 6.75 to 1.00 as of the last day of any fiscal quarter ending on or prior to June 30, 2020 and (y) 5.25 to 1.00 as of the last day of any fiscal quarter ending on or after September 30, 2020. The proceeds, net of applicable fees, of the Second Lien Term Loan Agreement were used to repay all amounts outstanding under the Senior Term Loan Agreement and to provide additional liquidity and working capital for the Company. Pursuant to the Second Lien Term Loan Agreement, the Company is required to issue 6.25 million detachable warrants to purchase common stock of the Company, which can be exercised on a cashless basis over a five -year term with an exercise price of $1.50 per share. 2.65 million warrants will not be issued unless approved by a shareholder vote; therefore, 90,667 shares of Series A Preferred Stock with a cumulative dividend rate of 18.0% were issued in the interim and will be canceled and converted into warrants upon receipt of shareholder approval, which is expected to occur at the Company’s 2019 Annual Meeting of Stockholders currently planned for June 25, 2019. In accordance with guidance in ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”) and ASC 815, “Derivatives and Hedging” (“ASC 815”), the (i) Second Lien Term Loan; (ii) the Series A Preferred Stock; and (iii) warrants are all freestanding instruments and proceeds were allocated to each instrument on a relative fair value basis: (i) $40.3 million ; (ii) $5.3 million and (iii) $5.4 million , respectively. The Series A Preferred Stock is not within the scope of ASC 480-10 and does not meet the criteria for liability classification. The Series A Preferred Stock will be classified as temporary equity as the Series A Preferred Stock will be entitled to receive two times its liquidation value in cash upon occurrence of a liquidation or deemed liquidation event, which is outside the control of the Company. The warrants also do not meet the criteria for liability classification under ASC 480. The warrants meet the definition of a derivative under ASC 815, however, are determined to be indexed to the Company’s own stock and meet the requirements for equity classification pursuant to ASC 815-40. The Company determined the fair value of the Second Lien Term Loan using a discount rate build up approach. The fair values of the Series A Preferred Stock and warrants were determined using an option pricing method. The debt discount of $10.7 million created by the relative fair value allocation of the equity component is being amortized as additional non-cash interest expense using the effective interest method over the contractual term of the loan. Debt issuance costs of approximately $3.8 million , and original issuance discount of approximately $1.0 million were incurred in connection with entry into the Second Lien Term Loan Agreement. The debt issuance and original issuance discount costs will be amortized into interest expense over the contractual term of the loan using the effective interest method. The Company had total unamortized debt issuance and discount costs of $15.5 million , all of which are recorded as a reduction of the debt balance on the Company’s accompanying condensed consolidated balance sheets. Convertible Notes In February 2017, the Company completed a public offering of 2.75% Convertible Senior Notes (the “Convertible Notes”) in an aggregate principal amount of $125.0 million . Interest is payable on January 1 and July 1 of each year, beginning on July 1, 2017. The Convertible Notes are convertible into 5,005,000 shares of the Company’s common stock, based on an initial conversion price of $24.98 per share. The Convertible Notes will mature on July 1, 2022 unless earlier converted. Upon conversion by the holders, the Company may elect to settle such conversion in shares of its common stock, cash, or a combination thereof. Because the Company may elect to settle conversion in cash, the Company separated the Convertible Notes into their liability and equity components by allocating the issuance proceeds to each of those components in accordance with ASC 470-20, “Debt-Debt with Conversion and Other Options.” The Company first determined the fair value of the liability component by estimating the value of a similar liability that does not have an associated equity component. The Company then deducted that amount from the issuance proceeds to arrive at a residual amount, which represents the equity component. The Company accounted for the equity component as a debt discount (with an offset to paid-in capital in excess of par value). The debt discount created by the equity component is being amortized as additional non-cash interest expense using the effective interest method over the contractual term of the Convertible Notes ending on July 1, 2022. In connection with the issuance of the Convertible Notes, the Company entered into convertible note hedge transactions (the “Convertible Note Hedges”) in privately negotiated transactions with certain of the underwriters or their affiliates (in this capacity, the “option counterparties”). The Convertible Note Hedges provide the Company with the option to acquire, on a net settlement basis, 5,005,000 shares of its common stock, which is equal to the number of shares of common stock that notionally underlie the Convertible Notes, at a strike price of $24.98 , which corresponds to the conversion price of the Convertible Notes. The Convertible Note Hedges have an expiration date that is the same as the maturity date of the Convertible Notes, subject to earlier exercise. The Convertible Note Hedges have customary anti-dilution provisions similar to the Convertible Notes. The Convertible Note Hedges have a default settlement method of net-share settlement but may be settled in cash or shares, depending on the Company’s method of settlement for conversion of the corresponding Convertible Notes. If the Company exercises the Convertible Note Hedges, the shares of common stock it will receive from the option counterparties to the Convertible Note Hedges will cover the shares of common stock that it would be required to deliver to the holders of the converted Convertible Notes in excess of the principal amount thereof. The aggregate cost of the Convertible Note Hedges was $29.0 million (or $7.5 million net of the total proceeds from the Warrants sold, as discussed below), before the allocation of issuance costs of approximately $0.7 million . The Convertible Note Hedges are accounted for as equity transactions in accordance with ASC 815-40 , “Derivatives and Hedging-Contracts in Entity’s own Equity.” In connection with the issuance of the Convertible Notes, the Company also sold net-share-settled warrants (the “Warrants”) in privately negotiated transactions with the option counterparties for the purchase of up to 5,005,000 shares of its common stock at a strike price of $29.60 per share, for total proceeds of $21.5 million , before the allocation of $0.6 million of issuance costs. The Company also recorded the Warrants within shareholders’ equity in accordance with ASC 815-40. The Warrants have customary anti-dilution provisions similar to the Convertible Notes. As a result of the issuance of the Warrants, the Company will experience dilution to its diluted earnings per share if its average closing stock price exceeds $29.60 for any fiscal quarter. The Warrants expire on various dates from October 2022 through February 2023 and must be net-settled in shares of the Company’s common stock. Therefore, upon exercise of the Warrants, the Company will issue shares of its common stock to the purchasers of the Warrants that represent the value by which the price of the common stock exceeds the strike price stipulated within the particular warrant agreement. Covenant and Liquidity Matters On May 7, 2019, the Company entered into the Seventh Amendment to Credit Agreement (the “Seventh Term Amendment”) to amend the First Lien Term Loan Agreement, which extended its $100.0 million prepayment requirement from on or before March 31, 2020, to on or before May 15, 2020. As a result of the modifications of the ABL Facility and the First Lien Term Loan, the additional liquidity from the Second Lien Term Loan, as well as the current forecast through June 2020, the Company believes it has sufficient liquidity to operate its business. In addition to meeting its working capital needs, the Sixth Term Amendment requires the Company to raise a minimum of $100.0 million through a combination of asset sales, junior debt or equity to make a contractually obligated prepayment of the First Lien Term Loan on or before May 15, 2020. We are currently evaluating all strategic alternatives related to the options to raise the funds necessary to comply with this contractual prepayment obligation. In conjunction with evaluating all strategic alternatives, the Company has created a board of directors’ subcommittee to oversee the fund-raising process and engaged an investment banker to assess management’s fund-raising alternatives. If we cannot generate the required cash, we may not be able to make the necessary payments required under our debt as of May 15, 2020, which would result in an event of default. Such a default, if not cured, would allow the lenders to accelerate the maturity of the debt, making it due and payable at that time. The Company is in compliance with all of its financial covenants as of March 31, 2019. Bank facilities There were $15.2 million and $2.9 million outstanding under the Company’s Australian loan agreement as of March 31, 2019 and December 31, 2018 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Foreign Currency Exchange Rate Risk As of March 31, 2019 , the Company was party to forward contracts to hedge changes in foreign currency exchange rates with notional amounts of approximately $21.9 million . The Company uses foreign currency forward contracts to mitigate the risk associated with fluctuations in currency rates impacting cash flows related to certain payments for contract manufacturing in its lower-cost manufacturing facilities. The foreign currency forward contracts hedge currency exposure between the Mexican peso and the U.S. dollar and between the Australian dollar and the U.S. dollar and mature at specified monthly settlement dates through December 2019. At inception, the Company designated the foreign currency forward contracts as cash flow hedges. Upon the performance of contract manufacturing or purchase of certain inventories the Company de-designates the foreign currency forward contract. On August 16, 2017, the Company’s Australian subsidiary entered into a cross currency swap arrangement to hedge changes in foreign currency exchange rates. As of March 31, 2019 , the notional amount of the cross currency swap was approximately $2.8 million . The Australian subsidiary uses the cross currency swap to mitigate the risk associated with fluctuations in currency rates related to a non-U.S. functional currency intercompany loan of NZ $10.0 million . The floating-to-floating cross currency swap hedges currency exposure between the New Zealand dollar and the Australian dollar and matures on June 30, 2020. The Australian subsidiary makes quarterly principal payments of NZ $0.8 million , plus interest at the 3-month Bank Bill Benchmark Rate in New Zealand plus a margin of 0.3% per annum, in exchange for A $0.8 million , plus interest at the three-month BBSY in Australia per annum. At inception, the cross currency swap was not designated as a hedging instrument.

Fair Value Measurements The fair value of the Company’s derivatives are estimated using an income approach based on valuation techniques to convert future amounts to a single, discounted amount. The Company’s derivatives are recorded at fair value in its condensed consolidated balance sheets and are valued using pricing models that are primarily based on market observable external inputs, including spot and forward currency exchange rates, benchmark interest rates, and discount rates consistent with the instrument’s tenor, and consider the impact of the Company’s own credit risk, if any. Changes in counterparty credit risk are also considered in the valuation of derivative financial instruments.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring The Company’s restructuring activities are undertaken as necessary to execute management’s strategy and streamline operations, consolidate and take advantage of available capacity and resources, and ultimately achieve productivity improvements and net cost reductions. The Company's restructuring charges consist primarily of employee costs (principally severance and/or termination benefits) and facility closure and other costs. To the extent these programs involve voluntary separations, no liabilities are generally recorded until offers to employees are accepted. If employees are involuntarily terminated, a liability is generally recorded at the communication date. Estimates of restructuring charges are based on information available at the time such charges are recorded. Related charges are recorded in cost of sales and selling, general and administrative expenses. The following table provides a summary of the Company’s consolidated restructuring liabilities and related activity for each type of exit cost as of and for the three months ended March 31, 2019 : Employee Costs Facility Closure and Other Costs Total (dollars in thousands) Balance at January 1, 2019 $ 4,990 $ 5,120 $ 10,110 Payments and other (1) (1,570 ) (410 ) (1,980 ) Balance at March 31, 2019 $ 3,420 $ 4,710 $ 8,130 (1) Other consists of changes in the liability balance due to foreign currency translation. The $8.1 million restructuring liability at March 31, 2019 includes $5.9 million of accrued liabilities and $2.2 million of other long-term liabilities.

Leases

Leases [Abstract]
Leases	Leases The Company leases certain facilities, automobiles and equipment under non-cancellable operating leases. Our leases have remaining lease terms of one year to thirteen years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within one year. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheets; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. Most leases include one or more options to renew. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to extend the lease terms are not included in the Company’s ROU assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal options and when they are reasonably certain of exercise, the Company includes the renewal period in the lease term. The Company combines lease and non-lease components which are accounted for as a single lease component as the Company has elected the practical expedient to group lease and non-lease components for all leases. As most of the Company’s leases do not provide an implicit rate, the Company uses the incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. The Company has a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, the Company applies a portfolio approach by reporting segment for determining the incremental borrowing rate. Operating lease cost for the three months ended March 31, 2019 was $ 5.3 million . Operating cash flows from operating leases and ROU assets obtained in exchange for operating lease obligations for the three months ended March 31, 2019 were $5.3 million and $1.1 million , respectively. The weighted average remaining term of these leases was approximately 6.1 years and the weighted average discount rate used to measure lease liabilities was approximately 7.6% . Maturities of lease liabilities were as follows as of March 31, 2019 : Years ending December 31, Operating Leases (dollars in thousands) 2019 $ 17,550 2020 16,720 2021 14,150 2022 10,080 2023 7,500 2024 and thereafter 23,160 Total lease payments 89,160 Less imputed interest (20,600 ) Present value of lease liabilities $ 68,560 Minimum payments for operating leases having initial or remaining non-cancellable lease terms in excess of one year at December 31, 2018 are summarized below: December 31, Minimum Payments (dollars in thousands) 2019 $ 15,820 2020 14,790 2021 12,590 2022 7,900 2023 4,830 Thereafter 13,090 Total $ 69,020

Commitments and Contingencies Disclosure [Abstract]
Contingencies	During the fourth quarter of 2018, the Company was notified by two OEM customers of potential claims related to product sold by Horizon Europe-Africa arising from potentially faulty components provided by a supplier. The claims resulted from the failure of products not functioning to specifications, but the claims do not allege any damage and only seek replacement of the product. One of the claims has since resulted in a recall campaign while the manner in which the other claim will be resolved is pending. The Company performed an assessment of the facts and circumstances for all asserted and unasserted claims and considered all factors including the Company’s recall insurance. Based on this assessment, the Company determined the probable range of the liability to be between $16.8 million and $20.0 million , with no amount within that range a better estimate than any other amount. As a result, the Company recorded a liability of $16.8 million and an asset of $11.1 million as of March 31, 2019 , which resulted in a $4.3 million charge during the three months ended March 31, 2019. The asset recorded represents the amount the Company believes is probable of recovery and has appropriate legal basis for recovery in accordance with its recall insurance policy. The Company cannot give any assurances that the final resolution of the claims, if adverse to the Company, will not have a material adverse effect to our financial position, results of operations or cash flows.

Earnings Per Share [Abstract]
Earnings per Share	Loss per Share Basic loss per share is computed using net loss attributable to Horizon Global and the number of weighted average shares outstanding. Diluted loss per share is computed using net loss attributable to Horizon Global and the number of weighted average shares outstanding, adjusted to give effect to the assumed exercise of outstanding stock options and warrants, vesting of restricted shares outstanding, and conversion of the Convertible Notes. The following table sets forth the reconciliation of the numerator and the denominator of basic loss per share attributable to Horizon Global and diluted loss per share attributable to Horizon Global: Three months ended 2019 2018 (dollars in thousands, except share and per share data) Numerator: Net loss attributable to Horizon Global $ (25,100 ) $ (57,510 ) Denominator: Weighted average shares outstanding, basic 25,188,094 24,963,120 Dilutive effect of stock-based awards — — Weighted average shares outstanding, diluted 25,188,094 24,963,120 Basic loss per share attributable to Horizon Global $ (1.00 ) $ (2.30 ) Diluted loss per share attributable to Horizon Global $ (1.00 ) $ (2.30 ) Due to net losses for the three months ended March 31, 2019 and 2018 , the effect of certain dilutive securities were excluded from the computation of weighted average diluted shares outstanding as inclusion would have resulted in anti-dilution. A summary of these anti-dilutive common stock equivalents is provided in the table below: Three months ended 2019 2018 Number of options 82,987 335,358 Exercise price of options $9.20 - $11.29 $9.20 - $11.29 Restricted stock units 472,627 647,717 Convertible Notes 5,005,000 5,005,000 Convertible Notes warrants 5,005,000 5,005,000 Second Lien Term Loan warrants 3,601,902 — For purposes of determining diluted loss per share, the Company has elected a policy to assume that the principal portion of the Convertible Notes, as described in Note 8 , “ Long-term Debt ,” is settled in cash and the conversion premium is settled in shares. Therefore, the Company has adopted a policy of calculating the diluted loss per share effect of the Convertible Notes using the treasury stock method. As a result, the dilutive effect of the Convertible Notes is limited to the conversion premium, which is reflected in the calculation of diluted loss per share as if it were a freestanding written call option on the Company’s shares. Using the treasury stock method, the Warrants issued in connection with the issuance of the Convertible Notes are considered to be dilutive when they are in the money relative to the Company’s average common stock price during the period. The Convertible Note Hedges purchased in connection with the issuance of the Convertible Notes are always considered to be anti-dilutive and therefore do not impact the Company’s calculation of diluted loss per share.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity Awards	Equity Awards Description of the Plan Horizon employees and non-employee directors participate in the Horizon Global Corporation 2015 Equity and Incentive Compensation Plan (as amended and restated, the “Horizon 2015 Plan”). The Horizon 2015 Plan authorizes the Compensation Committee of the Horizon Board of Directors to grant stock options (including “incentive stock options” as defined in Section 422 of the U.S. Internal Revenue Code), restricted shares, restricted stock units, performance shares, performance stock units, cash incentive awards, and certain other awards based on or related to our common stock to Horizon employees and non-employee directors. No more than 4.4 million Horizon common shares may be delivered under the Horizon 2015 Plan. Stock Options The following table summarizes Horizon stock option activity from December 31, 2018 to March 31, 2019 : Number of Stock Options Weighted Average Exercise Price Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Outstanding at December 31, 2018 92,967 $ 10.40 Granted — — Exercised — — Canceled, forfeited (28,973 ) 10.24 Expired — — Outstanding at March 31, 2019 63,994 $ 10.47 6.3 $ — As of March 31, 2019 , the unrecognized compensation cost related to stock options is immaterial. For the three months ended March 31, 2019 and 2018 , the stock-based compensation expense recognized by the Company related to stock options was immaterial. There was no aggregate intrinsic value of the outstanding options at March 31, 2019 . Stock-based compensation expense is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations. Restricted Shares During the first three months of 2019 , the Company granted an aggregate of 822,746 restricted stock units and performance stock units to certain key employees. The total grants consisted of: (i) 411,373 time-based restricted stock units that vest on March 19, 2022, and (ii) 411,373 market-based performance stock units that vest on March 19, 2022 (the “2019 PSUs”). During 2018, the Company granted an aggregate of 477,963 restricted stock units and performance stock units to certain key employees and non-employee directors. The total grants consisted of: (i) 5,680 time-based restricted stock units that vested on July 1, 2018; (ii) 43,799 time-based restricted stock units that vest ratably on (1) March 1, 2019, (2) March 1, 2020 and (3) March 1, 2021; (iii) 101,204 time-based restricted stock units that vest ratably on (1) March 1, 2019, (2) March 1, 2020, (3) March 1, 2021 and (4) March 1, 2022; (iv) 145,003 market-based performance stock units that vest on March 1, 2021 (the “2018 PSUs”); (v) 43,416 time-based restricted stock units that vest on March 1, 2021; (vi) 17,575 time-based restricted stock units that vest on May 8, 2019; (vii) 84,210 time-based restricted stock units that vested on May 15, 2018; (viii) 11,404 time-based restricted stock units that vest on May 15, 2020; (ix) 14,472 time-based restricted stock units that vest on August 1, 2020; (x) 8,400 time-based restricted stock units that vest on October 1, 2020, and (xi) 2,800 time-based restricted stock units that vest on December 3, 2020. The performance criteria for the market-based performance stock units is based on the Company’s total shareholder return (“TSR”) relative to the TSR of the common stock of a pre-defined industry peer group. For the 2019 PSUs, TSR is measured over a period beginning January 1, 2019 and ending December 31, 2021. For the 2018 PSUs, TSR is measured over a period beginning January 1, 2018 and ending December 31, 2020. TSR is calculated as the Company’s average closing stock price for the 20 -trading days at the end of the performance period plus Company dividends, divided by the Company’s average closing stock price for the 20 -trading days prior to the start of the performance period. Depending on the performance achieved, the amount of shares earned can vary from 0% of the target award to a maximum of 200% of the target award. The Company estimated the grant-date fair value of the awards subject to a market condition using a Monte Carlo simulation model, using the following weighted-average assumptions: risk-free interest rate of 2.43% and 2.34% for the 2019 PSUs and 2018 PSUs, respectively, and annualized volatility of 84.1% and 37.4% for the 2019 PSUs and 2018 PSUs, respectively. Due to the lack of adequate stock price history of Horizon common stock as of March 31, 2018, the volatility was based on the median of the peer group. In 2019, the Company had sufficient historical data that was used to calculate the volatility. The grant date fair value of the p erformance stock units wer e $3.69 and $7.08 for the 2019 PSUs and 2018 PSUs, respectively. The grant date fair value of r estricted stock units is expensed over the vesting period. Restricted stock unit fair values are based on the closing trading price of the Company’s common stock on the date of grant. Changes in the number of restricted shares outstanding for the period ended March 31, 2019 were as follows: Number of Restricted Shares Weighted Average Grant Date Fair Value Outstanding at December 31, 2018 419,928 $ 9.75 Granted 822,746 3.35 Vested (29,293 ) 11.02 Canceled, forfeited (67,159 ) 7.57 Outstanding at March 31, 2019 1,146,222 $ 4.88 As of March 31, 2019 , there was $3.8 million in unrecognized compensation costs related to unvested restricted stock units that is expected to be recognized over a weighted-average period of 2.6 years. The Company recognized approximately $0.4 million of stock-based compensation expense related to restricted shares during the three months ended March 31, 2019 , and approximately $0.7 million during the three months ended March 31, 2018 . Stock-based compensation expense is included in selling, general and administrative expenses in the accompanying condensed consolidated statements of operations.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim reporting period, the Company makes an estimate of the annual effective income tax rate. Tax items included in the annual effective income tax rate are pro-rated for the full year and tax items discrete to a specific quarter are included in the effective income tax rate for that quarter. Effective tax rates vary from period to period as separate calculations are performed for those countries where the Company's operations are profitable and whose results continue to be tax-effected and for those countries where full deferred tax valuation allowances exist and are maintained. In determining the estimated annual effective tax rate, the Company analyzes various factors, including but not limited to, forecasts of projected annual earnings, taxing jurisdictions in which the pretax income and/or pretax losses will be generated, available tax planning strategies and estimated domestic tax impacts attributable to the 2017 Tax Cuts and Jobs Act (the “Tax Act”). For the three months ended March 31, 2019 and 2018 , the effective income tax rate was (4.4)% and 4.3% , respectively. The lower 2019 effective tax rate is attributable to the valuation allowance recorded in the U.S. at year end 2018 , which resulted in no income tax benefit recognized for jurisdictional pretax losses. The Company evaluates the realizability of its deferred tax assets on a quarterly basis. In completing this evaluation, the Company considers all available evidence in order to determine whether, based on the weight of the evidence, a valuation allowance is necessary. Full valuation allowances against deferred tax assets in the U.S. and applicable foreign countries will be maintained until sufficient positive evidence exists to reduce or eliminate them. The factors considered by management in its determination of the probability of the realization of the deferred tax assets include, but are not limited to, recent historical financial results, historical taxable income, projected future taxable income, the expected timing of the reversals of existing temporary differences, tax planning strategies and projected future impacts attributable to the Tax Act. If, based upon the weight of available evidence, it is more likely than not the deferred tax assets will not be realized, a valuation allowance is recorded. As of March 31, 2019 , the Company believes that it is more likely than not that the recorded deferred tax assets will be realized. The Company has recently experienced pre-tax losses. If the Company continues to experience losses, management may determine a valuation allowance against certain of its deferred tax assets is necessary.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements Accounting pronouncements recently adopted In June 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-07, “Compensation - Stock Compensation (Topic 718)” (“ASU 2018-07”). ASU 2018-07 expands the scope of Accounting Standard Codification (“ASC”) 718 to include all share-based payment arrangements related to the acquisition of goods and services from both non-employees and employees. ASU 2018-07 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018 with early adoption permitted. The Company adopted ASU 2018-07 on January 1, 2019, and there was no impact on the Company’s condensed consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities” (“ASU 2017-12”). ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires, for qualifying hedges, the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also modifies the accounting for components excluded from the assessment of hedge effectiveness, eases documentation and assessment requirements and modifies certain disclosure requirements. ASU 2017-12 is effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted and should be applied on a modified retrospective basis. The Company adopted ASU 2017-12 on January 1, 2019, and there was no impact on the Company’s condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which supersedes the lease requirements in “Leases (Topic 840).” The objective of this update is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. Under this guidance, lessees are required to recognize on the balance sheet a lease liability and a right-of-use (“ROU”) asset for all leases, with the exception of short-term leases with terms of twelve months or less. The lease liability represents the lessee’s obligation to make lease payments arising from a lease and will be measured as the present value of the lease payments. The ROU asset represents the lessee’s right to use a specified asset for the lease term, and will be measured at the lease liability amount, adjusted for lease prepayment, lease incentives received and the lessee’s initial direct costs. The Company has elected the package of practical expedients, excluding the lease term hindsight, as permitted by the transition guidance. The Company has made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases will be expensed over the lease term. The Company adopted the standard on January 1, 2019, by applying the modified retrospective method without restatement of comparative periods' financial information, as permitted by the transition guidance. The standard had a material impact on the Company’s condensed consolidated balance sheets, but did not have an impact on its condensed consolidated statements of operations and cash flows. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while the Company’s accounting for finance leases remained substantially unchanged. See Note 11 “ Leases, ” for the impact of the adoption which resulted in the recognition of ROU assets and corresponding lease liabilities.
