Accounting Changes and Error Corrections [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Recent Accounting Pronouncements. In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU requires companies to record excess tax benefits and deficiencies in income rather than the current requirement to record them through equity. It also allows companies the option to recognize forfeitures of share-based awards when they occur rather than the current requirement to make an estimate upon the grant of the awards. This ASU is effective for public companies for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption will be permitted in any interim or annual period, with any adjustments reflected as of the beginning of the fiscal year of adoption. We are assessing the impact this new standard is anticipated to have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU requires lessees to recognize (with the exception of short-term leases) a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged and lessees will no longer be provided with a source of off-balance sheet financing. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. We are assessing the impact this new standard is anticipated to have on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This update amends the guidance regarding the classification and measurement of financial instruments. Changes to the current guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, it clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. This ASU is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. Upon adoption, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. We are assessing the impact this new standard is anticipated to have on our consolidated financial statements. In November 2015, the FASB issued Accounting Standards Update ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which will require deferred tax assets and deferred tax liabilities to be presented as noncurrent within a classified balance sheet. The ASU simplifies the current guidance which requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified balance sheet. The current requirement that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not affected. The ASU is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period, and this ASU may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We have elected not to early adopt this ASU, and we are evaluating whether to apply the provisions prospectively or retrospectively upon adoption. We do not presently anticipate that the adoption of this standard will have a material impact on our financial statements. In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This standard requires that inventory be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Inventory measured using last-in, first-out or the retail inventory method are excluded from the scope of this update which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. We do not anticipate that the implementation of ASU 2015-11 will have a material impact on our consolidated financial statements. In May 2014, the FASB issued authoritative guidance amending the FASB Accounting Standards Codification and creating a new Topic 606, Revenue from Contracts with Customers. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for U.S. GAAP applicable to revenue transactions. This guidance provides that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The existing industry guidance will be eliminated when the new guidance becomes effective and annual disclosures will be substantially revised. Additional disclosures will also be required under the new standard. In July 2015, the FASB approved a proposal that extended the required implementation date one year to the first quarter of 2018 but also would permit companies to adopt the standard at the original effective date of 2017. Implementation may be either through retrospective application to each period from the first quarter of 2016 or with a cumulative effect adjustment upon adoption in 2018. We are assessing the impact this new standard is anticipated to have on our consolidated financial statements.
