Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	12. Recent Accounting Pronouncements Recently Adopted In June 2011, the FASB issued ASU No. 2011-05, "Comprehensive Income (ASC Topic 220): Presentation of Comprehensive Income" ("ASU 2011-05"), which amends current comprehensive income guidance. This accounting update eliminates the option to present the components of other comprehensive income as part of the statement of shareholders' equity. Instead, the Company must report comprehensive income in either a single continuous statement of comprehensive income which contains two sections, net income and other comprehensive income, or in two separate but consecutive statements. ASU 2011-05 became effective for public companies during the interim and annual periods beginning after December 15, 2011 with early adoption permitted. The Company's adoption of ASU 2011-05 on January 1, 2012 did not have a material impact on the Company's consolidated financial statements as it only required a change in the format of the previous presentation. Recently Issued We have reviewed other recently issued accounting pronouncements and determined that they do not have a material impact on our consolidated financial statements.
