Deferred Tax Liability Not Recognized [Line Items]
Deferred Tax Liability Not Recognized, Description of Temporary Difference	The Company has unrecorded deferred income taxes on the undistributed earnings of its foreign subsidiaries. It is management's intent and practice to indefinitely reinvest such earnings outside of the U.S. to support the continuing operations of its foreign subsidiaries. As a result of the liquidity and financial strength of the Company's domestic operations, the Company does not currently anticipate a scenario where repatriation of these earnings would occur. At December 31, 2012, the aggregate undistributed earnings of the foreign subsidiaries (including cumulative unrealized currency gains related to previously taxed income) amounted to approximately $43,304,000.
