Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	2. Recent Accounting Pronouncements Recently Adopted Accounting Guidance In June 2011, the FASB issued ASU 2011-05 which provides new guidance on the presentation of comprehensive income. ASU 2011-05 eliminates the option to report other comprehensive income and its components in the statement of changes in stockholders’ equity and instead requires an entity 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 or in two separate but consecutive statements. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. The adoption of this ASU will not have a significant impact on the Company’s consolidated financial statements as it only requires a change in the format of the current presentation.

The entire disclosure for reporting accounting changes and error corrections. It includes the conveyance of information necessary for a user of the Company's financial information to understand all aspects and required disclosure information concerning all changes and error corrections reported in the Company's financial statements for the period.
