Significant Accounting Policies (Policies)	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation The interim condensed consolidated financial statements have been prepared according to U.S Generally Accepted Accounting Principles (“U.S. GAAP”). The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. For further information, reference is made to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10K for the year ended December 31, 2018. The significant accounting policies applied in the annual consolidated financial statements of the Company as of December 31, 2018, contained in the Company’s Annual Report on Form 10K filed with the Securities and Exchange Commission on March 4, 2019, have been applied consistently in these unaudited interim condensed consolidated financial statements, except for changes associated with recent accounting standards for leases, as detailed below.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Pronouncements On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016 - 02, Leases (“Topic 842” ), as amended, which supersedes the lease accounting guidance under Topic 840, and generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use (ROU) assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. The Company adopted the new guidance using the modified retrospective transition approach by applying the new standard to all leases existing on the date of initial application and not restating comparative periods. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases. For information regarding the impact of Topic 842 adoption, see Significant Accounting Policies - Leases and Note 5 - Leases. In August 2017, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2017 - 12, “Derivatives and Hedging (Topic 815 ): Targeted Improvements to Accounting for Hedging Activities,” amending the eligibility criteria for hedged items and transactions to expand an entity’s ability to hedge nonfinancial and financial risk components. The new guidance eliminates the requirement to separately measure and present hedge ineffectiveness and aligns the presentation of hedge gains and losses with the underlying hedge item. The new guidance also simplifies the hedge documentation and hedge effectiveness assessment requirements. The amended presentation and disclosure requirements must be adopted on a prospective basis, while any amendments to cash flow and net investment hedge relationships that exist on the date of adoption must be applied on a “modified retrospective” basis, meaning a cumulative effect adjustment to the opening balance of retained earnings as of the beginning of the year of adoption. The new guidance was effective for the Company on January 1, 2019 and the adoption did not have a material impact on the Company’s consolidated financial statements.
Lessee, Leases [Policy Text Block]	Significant Accounting Policies- Leases Effective as of January 1, 2019, the Company adopted Topic 842, which requires the recognition of lease assets and lease liabilities by lessees for leases classified as operating leases. The Company has adopted Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing on the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company’s historical accounting under Topic 840. The Company elected the package of practical expedients permitted under the transition guidance, which allowed the Company to carryforward the historical lease classification, the Company’s assessment on whether a contract was or contains a lease, and initial direct costs for any leases that existed prior to January 1, 2019. The Company also elected to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income (loss) on a straight-line basis over the lease term. As a result of the adoption of Topic 842 on January 1, 2019, the Company recorded both operating lease ROU assets of $9,785 and operating lease liabilities of $9,498. The ROU assets include adjustments for prepayments in the amount of $287. The adoption did not impact the Company’s beginning retained earnings, or its prior year condensed consolidated statements of income (loss) and statements of cash flows. The Company determines if an arrangement is a lease at inception. The Company’s assessment is based on: ( 1 ) whether the contract includes an identified asset, ( 2 ) whether the Company obtains substantially all of the economic benefits from the use of the asset throughout the period of use, and ( 3 ) whether the Company has the right to direct how and for what purpose the identified asset is used throughout the period of use. Leases are classified as either finance leases or operating leases. A lease is classified as a finance lease if any one of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset, the present value of the lease payments equals or exceeds substantially all of the fair value of the asset, or the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of lease term. A lease is classified as an operating lease if it does not meet any one of these criteria. Since all of the Company’s lease contracts do not meet any one of the criteria above, the Company concluded that all of its lease contracts should be classified as operation leases. ROU assets and liabilities are recognized on the commencement date based on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. The ROU asset also includes any lease payments made prior to commencement and is recorded net of any lease incentives received. All ROU assets are reviewed for impairment. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of the interim condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the dates of the interim condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reclassification, Policy [Policy Text Block]	Reclassification During the period, the Company changed the classification of prepaid expenses and other assets and deferred tax assets, net, in order to properly reflect the nature of such activities.
