Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	(18) 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 September 30, 2012 and December 31, 2011 under the Company’s credit facility approximates fair value because borrowings are for terms of less than six months and have rates that reflect currently available terms and conditions for similar debt.

The entire disclosure of the fair value measurement of assets and liabilities, which includes financial instruments measured at fair value that are classified in shareholders' equity, which may be measured on a recurring or nonrecurring basis.
