Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, “Leases (Accounting Standards Codification (ASC) 842),” and issued subsequent amendments to the initial guidance in January 2018 within ASU No. 2018-01 and in July 2018 within ASU Nos. 2018-10 and 2018-11. The Company adopted ASC 842 on January 1, 2019. See Note 8 for further details. In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (ASC 350), Simplifying the Test for Goodwill Impairment. The guidance removes Step 2 of the goodwill impairment test and eliminates the need to determine the fair value of individual assets and liabilities to measure goodwill impairment. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Entities will continue to have the option to perform a qualitative assessment to determine if a quantitative impairment test is necessary. The guidance will be applied prospectively and is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for any impairment tests performed on testing dates after January 1, 2017. The Company does not believe adoption will have a material impact on its financial condition or results of operations.
Revisions Policy [Policy Text Block]	Revisions Certain revisions have been made to the December 31, 2019 Condensed Consolidated Balance Sheet to conform to the current year presentation relating to a reclassification of long-term operating lease liabilities to current operating lease liabilities. The reclassification resulted in an increase of current operating lease liabilities of $476 thousand and a decrease of long-term operating lease liabilities of $476 thousand. These revisions had no impact on previously reported earnings, net income or cash flows and are deemed immaterial to the previously issued financial statements.
