Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. (“ASU”) 2016-09, "Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 will require all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also will allow an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years and early adoption is permitted. We are currently evaluating the effect ASU 2016-09 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-07, "Simplifying the Transition to the Equity Method of Accounting," which eliminates the requirement to retrospectively apply the equity method in previous periods when an investor initially obtains significant influence over an investee. Under current guidance, an investor that doesn’t consolidate an investment and initially accounts for it under a method other than the equity method is required to retrospectively apply the equity method in prior periods in which it held the investment when it subsequently obtained significant influence. ASU 2016-07 will be applied on a prospective basis and is effective for all entities for fiscal years beginning after December 15, 2016, and interim periods within those years and early adoption is permitted. We do not plan to early adopt ASU 2016-07 and currently do not expect it to affect our consolidated financial statements when adopted on January 1, 2017. In February 2016, the FASB issued ASU 2016-02, "Leases," which will require, among other items, lessees to recognize most leases as assets and liabilities on the balance sheet. Qualitative and quantitative disclosures will be enhanced to better understand the amount, timing and uncertainty of cash flows arising from leases. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. We do not plan to early adopt. ASU 2016-02 will be adopted on a modified retrospective basis, with elective reliefs, which requires application of ASU 2016-02 for all periods presented. We are currently evaluating the effect ASU 2016-02 will have on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." Amendments under ASU 2016-01, among other items, require that all equity investments in unconsolidated entities (other than those accounted for using the equity method of accounting) will generally be measured at fair value through earnings. There will no longer be an available-for-sale classification, for which changes in fair value are reported in other comprehensive income, for equity securities with readily determinable fair values. For equity investments without readily determinable fair values, the cost method is also eliminated. However, entities will be able to elect to record equity investments without readily determinable fair values at cost, less impairment, and plus or minus subsequent adjustments for observable price changes. Changes in the basis of these equity investments will be reported in current earnings. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We are currently evaluating the effect ASU 2016-01 will have, if any, on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Under ASU 2015-16, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The measurement period cannot exceed one year from the date of the acquisition. ASU 2015-16 was effective on January 1, 2016, and we adopted it at the same time as a change in accounting policy. For the first quarter of 2016, ASU 2015-16 had no effect on our consolidated financial statements. In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” Under current guidance, an entity subsequently measures inventory at the lower of cost or market, with market defined as replacement cost, net realizable value (NRV), or NRV less a normal profit margin. An entity uses current replacement cost provided that it is not above NRV (i.e., the ceiling) or below NRV less an “approximately normal profit margin” (i.e., the floor). ASU 2015-11 eliminates this analysis and requires entities to measure most inventory “at the lower of cost and NRV.” ASU 2015-11 is effective prospectively for annual periods beginning after December 15, 2016, and interim periods therein, with early adoption permitted. We will not early adopt. We are currently evaluating the effect ASU 2015-11 will have, if any, on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 was issued to simplify the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding debt liability. This makes the presentation of debt issuance costs consistent with the presentation of debt discounts or premiums. Under prior U.S. GAAP, debt issuance costs were reported on the balance sheet as assets and amortized as interest expense. Under ASU 2015-03, debt issuance costs will continue to be amortized to interest expense using the effective interest method. In August 2015, the FASB issued ASU 2015-15, "Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements" to clarify the SEC staff’s position that it would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, which is our current practice. We adopted ASU 2015-03 on January 1, 2016 on a retrospective basis as a change in accounting policy. The Condensed Consolidated Balance Sheet as of December 31, 2015, was retrospectively adjusted by decreasing Other assets and Long-term debt, net of current maturities by $1.8 million, respectively. In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in GAAP when it becomes effective. In August 2015, the FASB issued ASU 2015-14 to defer the effective date for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early adoption is permitted as of the original effective date in ASU 2014-09, which is annual reporting periods beginning after December 15, 2016, however, we will not early adopt. In April 2016, the FASB issued ASU 2016-10, "Identifying Performance Obligations and Licensing," which amends the guidance in ASU 2014-09 on accounting for licenses of intellectual property and identifying performance obligations. In March 2016, The FASB issued ASU 2016-08, "Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which amends the principal versus agent guidance in ASU 2014-09. The standards are to be applied retrospectively and permit the use of either the retrospective or cumulative effect transition method. We will use the cumulative effect transition method once we adopt ASUs 2014-09, 2016-10 and 2016-08 on January 1, 2018. We are currently evaluating the effect that these ASUs will have on our consolidated financial statements and related disclosures.
