Notes to Financial Statements
Significant Accounting Policies [Text Block]	3. Significant Accounting Policies and Recent Accounting Pronouncements We disclosed in Note 2 to our consolidated financial statements included in our Annual Report on Form 10 -K for the year ended December 31, 2018 those accounting policies that we consider significant in determining our results of operations and financial position. Other than as described below, there have been no material changes to, or in the application of, the accounting policies previously identified and described in the Form 10 -K. In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016 - 02, Leases (ASU 2016 - 02 ). ASU 2016 - 02 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to classify leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to prior guidance for operating leases. We adopted ASU 2016 - 02 effective January 1, 2019; such adoption had no material impact on our financial statements, given that the noncancelable term of our current lease is less than 12 months (see Note 8 ). There have been no other recent accounting pronouncements or changes in accounting pronouncements during the nine months ended September 30, 2019, as compared to the recent accounting pronouncements described in our Annual Report on Form 10 -K for the fiscal year ended December 31, 2018, which we expect to have a material impact on our financial statements.
