Recent Accounting Pronouncement [Abstract]
Recent Accounting Pronouncement	(15) Recent Accounting Pronouncement In June 2011, the Financial Accounting Standards Board issued revised guidance on the presentation of comprehensive income that will be effective for the Company beginning in 2012. This guidance eliminates the option to present the components of comprehensive income as part of the statement of shareholders’ equity and also requires presentation of reclassification adjustments from other comprehensive income to net income on the face of the financial statements. The implementation of this revised guidance in 2012 will change the presentation of the Company’s financial statements but will not have any impact on the Company’s financial position, results of operations or cash flows.
