Description of New Accounting Pronouncements Not yet Adopted [Text Block]	(20) Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued accounting standards update ("ASU") 2014 - 09, "Revenue from Contracts with Customers," which amends the accounting guidance related to revenues. This amendment will replace most of the existing revenue recognition guidance when it becomes effective. The new standard, as amended in July 2015, is effective for fiscal years beginning after December 15, 2017 and entities are allowed to adopt the standard as early as annual periods beginning after December 15, 2016, and interim periods therein. The standard permits the use of either the retrospective or cumulative effect transition method. We have evaluated the effect this amendment has on our most significant types of transactions and expect the timing of our revenue recognition to generally remain the same. We plan to apply a cumulative effect transition method at adoption. In July 2015, the FASB issued ASU 2015 - 11, "Simplifying the Measurement of Inventory (Topic 330)." ASU 2015 - 11 simplifies the accounting for the valuation of all inventory not accounted for using the last-in, first -out method by prescribing inventory be valued at the lower of cost or net realizable value. ASU 2015 - 11 is effective for public companies' annual periods, including interim periods within those fiscal years, beginning after December 15, 2016 on a prospective basis. Early adoption is permitted. We do not expect the adoption of ASU 2015 - 11 to have a material effect on our financial position, results of operations or cash flows. In February 2016, the FASB issued ASU 2016 - 02, "Leases." ASU 2016 - 02 increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requires disclosing key information about leasing arrangements. ASU 2016 - 02 is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. We are evaluating the effect this pronouncement will have on our consolidated financial statements and related disclosures. In March 2016, the FASB issued ASU 2016 - 09, "Compensation - Stock Compensation - Improvements to Employee Share-Based Payment Accounting." ASU 2016 - 09 simplifies the accounting for several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016 - 09 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. We believe this pronouncement will increase volatility in our effective tax rate, especially in the first quarter, as it relates to the recognition of the tax consequences of share-based payments. We plan to apply a prospective transition method associated with recognizing excess tax benefits and tax deficiencies in the income statement and will retrospectively apply amendments which impact the presentation of excess tax benefits on the cash flow statement. In August 2016, the FASB issued ASU 2016 - 15, "Classification of Certain Cash Receipts and Cash Payments." ASU 2016 - 15 provides guidance for eight cash flow classification issues to reduce diversity in practice. The clarification includes guidance on items such as debt prepayment or debt extinguishment cost, contingent consideration payment made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies and distributions received from equity method investees. ASU 2016 - 15 is effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted. We are evaluating the effect this pronouncement will have on our consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017 - 04, "Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment." ASU 2017 - 04 simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, if applicable. The loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. The same impairment test also applies to any reporting unit with a zero or negative carrying amount. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017 - 04 is effective for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. We do not expect the adoption of ASU 2017 - 04 to have a material effect on our financial position, results of operations or cash flows.
