Disclosure Text Block [Abstract] |
Fair Value, Measurement Inputs, Disclosure [Text Block] | (15) Fair Value of Financial Instruments Cash, accounts receivable, accounts payable and accrued liabilities are reflected in the consolidated financial statements at their carrying amount which approximates fair value because of the short-term maturity of those instruments. The carrying amount of debt outstanding at June 30, 2013 and December 31, 2012 under the Company’s credit facility entered into on May 12, 2011 (the “Credit Facility”) approximates fair value because the borrowing interest rates are for terms of less than six months and have rates that reflect currently available terms and conditions for similar debt.
