Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Adoption of New Accounting Standards 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 legacy GAAP and reflect an entity’s current estimate of all expected credit losses. On January 1, 2020, we adopted ASU 2016-13 using the modified retrospective transition method, resulting in a cumulative effect adjustment that decreased the opening balance of retained earnings by less than $0.1 million. The standard did not materially impact our consolidated statements of operations and comprehensive income or consolidated cash flows.

Adoption of New Accounting Standards

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 legacy GAAP and reflect an entity’s current estimate of all expected credit losses. On January 1, 2020, we adopted ASU 2016-13 using the modified retrospective transition method, resulting in a cumulative effect adjustment that decreased the opening balance of retained earnings by less than $0.1 million. The standard did not materially impact our consolidated statements of operations and comprehensive income or consolidated cash flows.
