Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	*Use of Estimates* The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Significant items subject to such estimates and assumptions include the useful lives of property, plant and equipment, intangibles, impairment of goodwill, valuation allowances for deferred tax assets, leases and provision for doubtful debts, and restructuring costs. Management believes that the estimates used in the preparation of the consolidated financial statements are reasonable, and management has made assumptions about the possible effects of the novel coronavirus (“COVID-19”) pandemic on critical and significant accounting estimates. Although these estimates are based upon management’s best knowledge of current events and actions, actual results could differ from these estimates. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.
Revenue from Contract with Customer [Policy Text Block]	*Revenue* The Company utilizes a five-step process given in ASC 606, for revenue recognition that focuses on the transfer of control, rather than the transfer of risks and rewards. It also provided additional guidance on accounting for contract acquisition and fulfillment costs. Refer to Note 4 on "Revenue from Contracts with Customers" for further information.
Lessee, Leases [Policy Text Block]	*Leases* We determine if an arrangement is a lease at inception. Operating leases are included in right-of-use (“ROU”) assets, current maturity of operating lease liabilities, and operating lease liabilities in our consolidated balance sheet. Finance leases are included in property plant and equipment, long-term debt, accrued expenses, and other current liabilities in our consolidated balance sheet. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of remaining lease payments over the balance lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the date of initial application on determining the present value of lease payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain to exercise that option. Lease expense is recognized on a straight-line basis over the lease term. The Company elected the practical expedient permitted under the transition guidance under Topic 842, which among other matters, allowed the Company (i) not to apply the recognition requirements to short-term leases (leases with a lease term of 12 months or less), (ii) not to reassess whether any expired or existing contracts are or contain leases, (iii) not to reassess the lease classification for any expired or existing leases, and (iv) not to reassess initial direct costs for any existing leases. We have lease agreements with lease and non-lease components, which are generally accounted for separately. Rent discounts and deferment of rent that were received due to COVID-19 have been accounted for without lease modification using the practical expedient provided by the FASB. Refer to Note 13 "Leases" for information and related disclosures.
Business Combinations Policy [Policy Text Block]	*Business Combinations* The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, Business Combinations, by recognizing identifiable tangible and intangible assets acquired, liabilities assumed, and non-controlling interests in the acquired business at their fair values. The excess of the cost of the acquired business over the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed is recorded as goodwill. Acquisition-related costs are expensed as incurred.
Goodwill and Intangible Assets, Policy [Policy Text Block]	*Goodwill and Intangible Assets* Goodwill represents the cost of acquired businesses in excess of the fair value of identifiable tangible and intangible net assets purchased. Goodwill is not amortized but is tested for impairment at least on an annual basis on December 31, based on a number of factors, including operating results, business plans, and future cash flows. The Company performs an assessment of qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Based on the assessment of events or circumstances, the Company performs a quantitative assessment of goodwill impairment if it determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, based on the quantitative impairment analysis, the carrying value of a reporting unit exceeds the fair value of reporting units, an impairment loss is recognized in an amount equal to the excess. In addition, the Company performs a quantitative assessment of goodwill impairment between annual tests if an event occurs or circumstances change that would be more likely than not reduce the fair value of a reporting unit below its carrying amount. Refer to Note 3 for information and related disclosures. Intangible assets acquired in a business combination were recorded at fair value at the acquisition date using generally accepted valuation methods appropriate for the type of intangible asset. Intangible assets with definite lives are amortized over the estimated useful lives and are reviewed for impairment at least annually, or more frequently if indicators of impairment arise. Refer to Note 3 on "Goodwill and Intangible assets" for further information.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	*Foreign Currency Matters* The Company has operations in Argentina and its functional currency has historically been the Argentine Peso. The Company monitors inflation rates in countries where it operates as required by US GAAP. Under ASC 830-10-45-12, an economy must be classified as highly inflationary when the cumulative three-year rate exceeds 100%. Considering the inflation data of Argentina, the Company has considered Argentina to be highly inflationary beginning on July 1, 2018. In accordance with ASC 830, the functional currency of the Argentina business has been changed to USD, which requires re-measurement of the local books to USD. Exchange gains and losses are recorded through net income instead of through other comprehensive income as had been done historically. Translation adjustments from periods prior to the change in functional currency were not removed from equity.
Equity Method Investments [Policy Text Block]	Investment in equity-accounted investees Investment in equity-accounted investee is an entity over which the Company has significant influence and which is neither a subsidiary nor a joint arrangement. Significant influence is the power to participate in the investee's financial and operating policy decisions of the investee but is not control or joint control over those policies. Investment in equity-accounted investee is accounted using the equity method of accounting. Under the equity method, the investment in equity-accounted investees is initially recognized at cost and adjusted thereafter for the post-acquisition changes in the Company’s share of net assets of the equity-accounted investees. Goodwill relating to an investment in equity-accounted investees, if any, is included in the carrying amount of the investment and is neither amortized nor individually tested for impairment. The consolidated statement of income (loss) reflects the Company’s share of the results of operations of the equity-accounted investees. When there has been a change recognized directly in the equity of the equity-accounted investees, the Company recognizes its share of any changes and discloses this, when applicable, in the statement of stockholders' equity. Unrealized gains and losses resulting from transactions between the Company and the equity-accounted investment are eliminated to the extent of the interest in the equity-accounted investees. The Company’s share of profit/loss of equity-accounted investees is shown on the face of the consolidated statement of income (loss). The financial statements of the equity-accounted investee are prepared for the same reporting period as the Company. When necessary, adjustments are made to bring the accounting policies in line with those of the Company. After the application of the equity method, the Company determines at each reporting date whether there is any objective evidence that the investment in equity-accounted investees is impaired if there has been other than a temporary decline in carrying value. If this is the case, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognizes the amount in the ‘share of income/ (loss) of equity-accounted investees' in the consolidated statement of income (loss).
Share-based Payment Arrangement [Policy Text Block]	*Stock-Based Compensation* We recognize expenses related to all share-based payments to employees, including grants of employee stock options, based on the grant-date fair values amortized straight-line over the period during which the employees are required to provide services in exchange for the equity instruments. We include an estimate of forfeitures when calculating compensation expenses. We use the Black-Scholes method for valuing stock-based awards. See Note 10, “Share-Based Compensation” for further information.
Common Stock Warrant Accounting, Policy [Policy Text Block]	*Common Stock Warrant Accounting* We account for common stock warrants as equity instruments, based on the specific terms of our warrant agreement. For more information refer to Note 10, "Share-Based Compensation."
New Accounting Pronouncements, Policy [Policy Text Block]	*Recent Accounting Pronouncements* In June 2016, FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) ("ASU 2016-13"), Measurement of Credit Losses on Financial Instruments. The standard significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren't measured at fair value through net income. The standard will replace today's "incurred loss" approach with an "expected loss" model for instruments measured at amortized cost. For available-for-sale debt securities, entities will be required to record allowances rather than reduce the carrying amount, as they do today under the other-than-temporary impairment model. It also simplifies the accounting model for purchased credit-impaired debt securities and loans. This ASU is effective for annual periods beginning after December 15, 2022, and interim periods therein for smaller reporting companies. We do not expect the adoption of ASU 2016-13 will have a material impact on our consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” This ASU provides temporary optional expedients and exceptions to the guidance in US GAAP on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (“LIBOR”) and other interbank offered rates to alternative reference rates, such as the Secured Overnight Financing Rate (“SOFR”). Entities can elect not to apply certain modification accounting requirements to contracts affected by what the guidance calls reference rate reform if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. The guidance is effective upon issuance and generally can be applied through December 31, 2022. The Company is still in the process of assessing the impact of this ASU.
