BUSINESS Business (Policies)	12 Months Ended
Dec. 31, 2015
Subsequent Events, Policy [Policy Text Block]	In the first quarter of 2016, the Company commenced restructuring actions that are part of a broad restructuring plan encompassing a series of measures intended to allow the Company to more efficiently operate in a leaner, and more directed cost structure. These include reductions in the Company’s workforce, facilities consolidation, transferring certain business processes to lower cost regions, and reducing other third-party services costs. In connection with this restructuring plan, the Company expects to incur incremental cash expenditures of approximately $25 million relating to termination benefits, facility costs, employee overlap expenses and related actions. The Company anticipates that the restructuring plan will be substantially complete by the end of the second quarter of 2017 and when fully implemented, is expected to result in annualized costs savings of appropriately $68 million. In connection with the cost efficiency program, on February 26, 2016, the Company entered into a term loan with an aggregate principal amount of $100 million and up to a maximum of $5 million in revolving credit (collectively, the “Financing Agreement”). All outstanding loans under the Financing Agreement will become due and payable in February 2021, or in May 2020 if the $125.0 million in outstanding principal from the 2.00% convertible senior notes due June 15, 2020 have not been repaid or refinanced. The Financing Agreement requires the Company to comply with a financial statement covenant that stipulates a maximum leverage ratio commencing in June 30, 2016. Proceeds from the Financing Agreement will be used to replace the existing $35 million revolving credit facility, finance the Company’s efficiency program and other initiatives, and provide operating flexibility throughout the remainder of the transformation in this period of heightened market volatility. The Company estimates that after paying for both debt issuance costs and the efficiency program, the new financing will provide approximately $70 million of available liquidity, about half of which replaces the existing revolving credit facility with the remainder providing incremental liquidity to fund operations. Concurrent with entering into the Financing Agreement, the Company terminated its existing revolving credit agreement, and repaid all outstanding borrowings under the revolving credit agreement. There were no penalties paid by the Company in connection with the termination of the revolving credit agreement.
