Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	(11) Financial Instruments The FASB issued ASC Topic 815, Derivatives and Hedging (“ASC 815”) which establishes accounting and reporting standards for derivative instruments. ASC 815 requires an entity to recognize all derivatives as either assets or liabilities and measure those instruments at fair value. Derivatives that do not qualify as a hedge must be adjusted to fair value in earnings. If the derivative does qualify as a hedge under ASC 815, changes in the fair value will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments or recognized in accumulated other comprehensive income (loss) until the hedged item is recognized in earnings. The ineffective portion of a hedge’s change in fair value will be immediately recognized in earnings. Beginning in the second quarter of 2013, in order to protect against foreign currency exposure in its Australian operations, the Company entered into forward foreign currency contracts as a hedge of AUD $60.0 million of its net investment in Australia. Beginning in the third quarter of 2013, the Company also entered into forward foreign currency contracts as a hedge of £40.0 million of its net investment in the U.K. The Company settled certain of its hedge positions during the 2015 year and received $2.9 million in net proceeds. This amount was classified in accumulated other comprehensive loss in the Company’s Consolidated Balance Sheet (see Note 2), offsetting the currency translation adjustment of the related net investment that is also recorded in accumulated other comprehensive loss, and is reported net of the effect of income taxes. As of December 31, 2014, the Company had a net asset of $272,000 recorded in other current liabilities with the offsetting net unrealized gain being recorded in accumulated other comprehensive loss in its Consolidated Balance Sheets associated with open forward foreign currency contracts which matured in January of 2015. As of June 30, 2015, the Company had a gross liability of $2.1 million recorded in other current liabilities, with the offsetting net unrealized loss being recorded in accumulated other comprehensive loss in its Consolidated Balance Sheets associated with open forward foreign currency contracts which matured in July of 2015. The Company does not enter into derivative transactions for speculative purposes.
