Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	14. INCOME TAXES The tax impact of the year to date fair value adjustment to the long term contingent consideration liability was recorded in the interim periods as a reliable estimate of the full year adjustment could not be reasonably made. Additionally, unrecognized tax benefits of approximately $7.6 million may be recognized within the next 12 months. The Company has historically provided deferred taxes under ASC 740-30-25, formerly APB 23, for the presumed repatriation to the United States earnings from several non-U.S. subsidiaries. The indefinite reversal criterion of ASC 740-30-25 allows the Company to overcome that presumption to the extent the earnings are indefinitely reinvested outside the United States. In June 2014, the Company determined that approximately $23.7 million of certain foreign subsidiaries’ undistributed net earnings would now be indefinitely reinvested in operations outside the United States. These earnings will provide the Company an opportunity to reinvest in the existing international business and provide funding for future acquisitions outside of the United States. As a result of the change in assertion, the Company reduced its deferred tax liabilities related to undistributed foreign earnings by $4.5 million as a discrete item in the second quarter.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
