Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Accounting Standards Update In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606), which outlines a comprehensive new revenue recognition model designed to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606)-Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which further clarifies the implementation guidance on principal versus agent considerations contained in ASU 2014-09. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606)-Identifying Performance Obligations and Licensing, which further clarifies the implementation guidance relating to identifying performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)-Narrow-Scope Improvements and Practical Expedients, which further clarifies guidance on collectability, noncash consideration, presentation of sales tax, practical expedients and transition. In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which makes minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. These standards, pursuant to ASU No. 2015-14, Revenue from Contracts with Customers-Deferral of the Effective Date (Topic 606) issued by the FASB in August 2015, will be effective for annual periods (including interim periods) beginning after December 15, 2017. The Company commenced its assessment of these new standards during the second half of 2016, developed a project plan to guide the implementation and is evaluating the impact these new standards will have on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments. This standard requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer must record, in the same period's financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting has been completed at the acquisition date. The Company adopted this guidance on January 1, 2016 and there was no impact on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. It is effective for annual periods (including interim periods) beginning after December 15, 2018, and early adoption is permitted. The Company is evaluating the impact the provisions of ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), which is intended to simplify the accounting for the taxes related to stock-based compensation. Under the new guidance excess tax benefits and tax deficiencies will be recognized as income tax benefit or expense in the income statement, rather than in the balance sheet within additional paid-in capital. The new guidance also makes amendments to the following areas: presentation of excess tax benefits or tax deficiencies on the statement of cash flows, accounting for forfeitures and presentation of employee taxes paid on the statement of cash flows when an employer withholds shares to meet minimum statutory withholding requirements. It is effective for annual periods (including interim periods) beginning after December 15, 2016. The Company adopted this guidance on January 1, 2017 and as required will prospectively present excess tax benefits and deficiencies in its consolidated statement of operations and comprehensive income (no longer as increases to additional paid in capital on its consolidated balance sheet). Additionally the Company will retrospectively present its gross excess tax benefits as cash flows from operating activities in its consolidated statements of cash flows (no longer as cash flows from financing activities). The tax effect related to stock-based awards is dependent on the Company's stock price and as a result it is subject to significant fluctuations. The Company will continue to estimate expected forfeitures to determine the amount of compensation expense to be recognized. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update is effective for annual periods (including interim periods) beginning after December 15, 2017, should be applied retrospectively, and early adoption is permitted. The Company adopted this guidance as of December 31, 2016 and there was no impact on its consolidated financial statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements, which clarifies and removes inconsistencies in key areas of accounting principles generally accepted in the United States (“GAAP”) and is effective immediately. The Company adopted this guidance in December 2016 and there was no impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805) Clarifying the Definition of a Business. The amendments in this update clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-03, Intangibles-Goodwill and Other (Topic 350) Simplifying the Test for Goodwill Impairment. The new guidance eliminates Step 2 of the goodwill impairment test which requires companies to calculate the implied fair value of goodwill, determined in the same manner as the amount of goodwill recognized in a business combination, and using a hypothetical purchase price allocation. Under the new guidance, goodwill impairment will now be measured as the amount by which a reporting unit’s carrying value exceeds its fair value. This update is effective for annual periods (including interim periods) beginning after December 15, 2017, and early adoption is permitted. The Company does not expect the adoption of this guidance will have a material impact on its consolidated financial statements.
