New Accounting Pronouncements, Policy [Policy Text Block]

Issued Accounting Standards Not Yet Adopted

Leases

In February 2016, the FASB issued ASU No. 2016-02, "Leases" ("ASU 2016-02"). ASU 2016-02 requires lessees to recognize on the balance sheet a right-of-use asset, representing its right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing, and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for us in the first quarter of fiscal year 2020, and early application is permitted. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases and ASU 2018-11, Leases Topic 842 Target improvements, which provides an additional (and optional) transition method whereby the new lease standard is applied at the adoption date and recognized as an adjustment to retained earnings. We are currently evaluating the impact of our pending adoption of ASU 2016-02 on our condensed consolidated financial statements, and we currently expect that most of our operating lease commitments will be subject to the new standard and recognized as operating lease liabilities and right-of-use assets upon our adoption of ASU 2016-02, which will increase our total assets and total liabilities that we report relative to such amounts prior to adoption.

Other Accounting Pronouncements

In January 2018, the FASB issued ASU 2018-02, "Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income ("AOCI"), which is effective for fiscal years beginning after December 15, 2018 and interim periods therein, with early adoption permitted. The guidance gives entities the option to reclassify to retained earnings the tax effects resulting from the Tax Cuts and Jobs Act ("TCJA") related to items in AOCI. The new guidance may be applied retrospectively to each period in which the effect of TCJA is recognized in the period of adoption. We do not expect the implementation to have a material impact on our consolidated financial statements.
