Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	*New Accounting Standards* **Not Yet Adopted** In June 2016, the Financial Standards Accounting Board (FASB) issued Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which represents a new credit loss standard that will change the impairment model for most financial assets and certain other financial instruments. Specifically, this guidance will require entities to utilize a new “expected loss” model as it relates to trade and other receivables. In addition, entities will be required to recognize an allowance for estimated credit losses on available-for-sale debt securities, regardless of the length of time that a security has been in an unrealized loss position. This guidance will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods, and early adoption is permitted. The Company is currently evaluating the potential impact that the adoption of this guidance may have on the Company’s consolidated financial statements. *Recently Adopted Accounting Standards* On April 1, 2019, the Company adopted ASU 2018-15, Intangibles – Goodwill and Other – Internal-Use Software: Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. This guidance was issued to address the diversity in practice related to the accounting for costs of implementation activities performed in a cloud computing arrangement that is a service contract. The Company adopted this standard prospectively, impacting all implementation costs incurred after adoption. The adoption did not have a material impact on the Company’s results of operations and financial position. On January 1, 2019, the Company adopted ASU 2016-02, Leases. This guidance was issued to increase transparency and comparability among organizations by requiring the recognition of lease assets and lease liabilities in the balance sheet and by disclosing key information about leasing arrangements. The Company adopted this standard using the modified retrospective approach as of the date of adoption, meaning no prior period balances were impacted by the adoption. Additionally, the Company elected to adopt the standard using the package of practical expedients permitted under the standard’s transition guidance, which allowed the Company to carryforward its historical lease classifications, and embedded lease and initial direct cost assessments. The adoption of the standard had a material impact on the Company’s condensed consolidated balance sheet primarily related to the recognition of right-of-use (ROU) assets and lease liabilities for operating leases. However, the adoption did not have a material impact on the condensed consolidated statement of comprehensive income and statement of cash flows. Refer to Note 9, “Leases,” for further information regarding the Company’s leases. On January 1, 2019, the Company adopted ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This guidance was issued to address the impact of the change in the U.S. federal corporate income tax rate from the 2017 U.S. Tax Cuts and Jobs Act (the “Tax Act”) on items recorded as a component of accumulated other comprehensive income (AOCI). This guidance allows companies to reclassify to retained earnings the stranded tax effects lodged in AOCI as a result of the Tax Act. Upon adoption of the ASU, the Company elected to not reclassify the stranded income tax effects from AOCI to retained earnings. There are several new accounting pronouncements issued by the FASB. Each of these pronouncements, as applicable, has been or will be adopted by the Company. Management does not believe any of these accounting pronouncements has had or will have a material impact on the Company’s consolidated financial statements.
