Accounting Standards Update and Change in Accounting Principle [Text Block] | 3. Recent Accounting Pronouncements: Recent Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”), which provides optional guidance for a limited period of time to ease the potential burden of reference rate reform on financial reporting. The amendments in ASU 2020-04 apply to contract modifications that replace a reference rate affected by reference rate reform and contemporaneous modifications of other contract terms related to the replacement of the reference rate. The following optional expedients for applying the requirements of certain Topics or Industry Subtopics in the Codification are permitted for contracts that are modified because of reference rate reform and that meet certain scope guidance:
| 1. | Modifications of contracts within the scope of Topics 310, Receivables, and 470, Debt, should be accounted for by prospectively adjusting the effective interest rate.
| 2. | Modifications of contracts within the scope of Topic 842, Leases, should be accounted for as a continuation of the existing contracts with no reassessments of the lease classification and the discount rate or remeasurements of lease payments that otherwise would be required under those Topics for modifications not accounted for as separate contracts.
| 3. | Modifications of contracts do not require an entity to reassess its original conclusion about whether that contract contains an embedded derivative that is clearly and closely related to the economic characteristics and risks of the host contract under Subtopic 815-15, Derivatives and Hedging— Embedded Derivatives
The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. The Company is currently charged interest and standby fees associated with its Amended 2019 Credit Facility (as defined below) based on LIBOR which are partially hedged by interest rate swaps, which are also based on LIBOR. Both the credit facility agreement and the interest rate swaps will need to be amended when an alternative reference rate is chosen, at which time we may adopt some of the practical expedients provided by ASU 2020-04.
