Debt [Abstract]
Debt Disclosure [Text Block]	Note 10 – Debt As discussed in the Current Report on Form 8-K filed on June 17, 2013, the Company entered into a revised syndicated multicurrency credit facility on June 14, 2013, which amends and replaces the Company's previous credit facility with Bank of America, N.A. and certain other major financial institutions. The revised facility increases the maximum principal amount available for revolving credit borrowings from $175,000 to $300,000, which can be increased to $400,000 at the Company's option if the lenders agree and the Company satisfies certain conditions. This facility matures in June 2018. In addition, the revised facility amends certain financial, acquisition and other covenants, but the consolidated leverage ratio calculation, for which access to credit under the former facility largely depended upon, remains relatively consistent and cannot exceed 3.50 to 1. At June 30, 2013 and December 31, 2012, the consolidated leverage ratio was below 1.0 to 1 and the Company was also in compliance with all of the other covenants. At June 30, 2013 and December 31, 2012, the Company had approximately $5,000 and $12,200 outstanding under this revised facility and the Company's former facility, respectively.
