Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation These condensed Consolidated Financial Statements contain unaudited information as of September 30, 2016 and for the three and nine months ended September 30, 2016 and 2015. The unaudited interim financial statements have been prepared pursuant to the rules and regulations for reporting on Form 10-Q. Accordingly, certain disclosures required by accounting principles generally accepted in the United States of America for annual financial statements are not included herein. In management’s opinion, these unaudited financial statements reflect all adjustments (which include only normal recurring adjustments) necessary for a fair presentation of the information when read in conjunction with our 2015 audited Consolidated Financial Statements and the related notes thereto. The financial information as of December 31, 2015 is derived from our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 26, 2016. The interim condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the notes thereto included in our 2015 Annual Report on Form 10-K. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
Reclassification, Policy [Policy Text Block]	Reclassifications Certain reclassifications of amounts previously reported have been made to the accompanying condensed Consolidated Financial Statements to maintain consistency and comparability between periods presented. These reclassifications had no impact on previously reported net income.
New Accounting Pronouncements, Policy [Policy Text Block]	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 are evaluating the effect this amendment will have on our consolidated financial statements and related disclosures and believe the financial impact is not material. We have not yet selected a transition method. 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 are evaluating the effect this pronouncement will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method. 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.
