| Commitments and Contingencies Disclosure [Text Block] | 9.                  CONTINGENCIESThe Company is      subject to litigation and other claims that arise in the      ordinary course of business. While the ultimate result of the      Company's outstanding legal matter described under "Legal      Proceedings" in the Company's Annual Report on Form 10-K for      the fiscal year ended December 31, 2012 cannot presently be      determined, the Company does not expect that the ultimate      disposition will have a material adverse effect on its      results of operations or financial condition. However, legal      matters are inherently unpredictable and subject to      significant uncertainties, some of which are beyond the      Company's control. As such, there can be no assurance that      the final outcome will not have a material adverse effect      upon the Company's financial condition or results of      operations. |
