New Accounting Pronouncements, Policy [Policy Text Block]	Adoption of New Accounting Standards Accounting Standards Update (“ASU”) 2016-02, Leases (“ASU 2016-02”) is codified in ASC 842, Leases (“ASC 842”). ASC 842 supersedes current lease guidance in ASC 840 and requires a lessee to recognize a right-of-use asset and a corresponding lease liability for substantially all leases. The lease liability will be equal to the present value of the remaining lease payments while the right-of-use asset will be similarly calculated and then adjusted for initial direct costs. In addition, ASC 842 expands the disclosure requirements to increase the transparency and comparability of the amount, timing and uncertainty of cash flows arising from leases. On January 1, 2019, we adopted ASC 842 using the modified retrospective transition method. We elected available practical expedients permitted under the transition guidance within the new standard, which among other items, allowed the Company to carry forward its historical lease classification and not reassess existing leases under the new definition of a lease in ASC 842. In addition, we will account for lease and non-lease components as a single lease component. Adoption of ASC 842 resulted in the recording of additional net lease assets and lease liabilities of $34.2 million and $34.3 million, respectively, as of January 1, 2019. The difference between the additional lease assets and lease liabilities, net of the deferred tax impact, was recorded as an adjustment to retained earnings. The standard did not materially impact our consolidated statements of operations and comprehensive income or consolidated cash flows. *Accounting Standards Issued But Not* Yet Adopted** In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held. The amendments in ASU 2016-13 eliminate the probable threshold for initial recognition of a credit loss in current GAAP and reflect an entity’s current estimate of all expected credit losses. ASU 2016-13 is effective for our interim and annual reporting periods beginning January 1, 2020, and is to be applied using a modified retrospective transition method. Earlier adoption is permitted. We do not plan to early adopt ASU 2016-13 and with our current holdings of financial instruments that are subject to credit losses, we do not believe adoption of this guidance will have a material impact on our financial statements.
