ASU 2014-09 Revenue from Contracts with Customers [Member]
Interim Statement Presentation [Line Items]
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 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 U.S. GAAP. The new standard is effective for the Company in the first quarter of 2018. The standard permits the use of either the retrospective or cumulative effect transition method. At this time, we have not selected a transition method. We are currently evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures.

Interim Statement Presentation [Line Items]
New Accounting Pronouncements, Policy [Policy Text Block]	In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, which requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying value of the debt liability. ASU 2015-03 is effective for the Company in the first quarter of 2016, with early adoption permitted, and retrospective application required. The Company has chosen to adopt the standard early, effective in the first quarter of 2015. The adoption of ASU 2015-03 did not have a material impact on our condensed consolidated financial statements. Refer to Note (9) for further information regarding debt issuance costs.

New Accounting Pronouncements, Policy [Policy Text Block]	In February 2015, the FASB issued ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis, which provides guidance when evaluating whether to consolidate certain legal entities. The updated guidance modifies evaluation criteria of limited partnerships and similar legal entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the consolidation analysis of reporting entities that are involved with variable interest entities, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for the Company in the first quarter of 2016, with early adoption permitted. We are currently evaluating the effect that ASU 2015-02 will have on our consolidated financial statements and related disclosures.

Reclassifications [Text Block]	Amortization of acquisition-related intangibles includes the amortization of customer relationships, acquired technology, trade names, and non-compete agreements recorded in connection with our business acquisitions. Historically, such amounts were included in general and administrative expense in our condensed consolidated statements of operations. Effective for our second quarter of 2015, amortization of acquisition-related intangibles is presented on a separate line within our condensed consolidated statements of operations. While this reporting change did not impact our consolidated results, prior period reclassifications have been made to conform to the current period presentation.

While this reporting change did not impact our consolidated results, prior period reclassifications have been made to conform to the current period presentation.
