Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements In June 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2011-05, Presentation of Comprehensive Income, an amendment to Accounting Standards Codification ("ASC") Topic 220, Comprehensive Income. The update gives companies the option to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in the update do not change the items that must be reported in other comprehensive income or when an item of other comprehensive income must be reclassified to net income. The ASU is effective for the Company for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company does not expect the impact of adopting this ASU to be material to the Company's financial position, results of operations or cash flows.
