In June 2011, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2011-05, "Presentation of Comprehensive Income." This standard eliminates the option to report other comprehensive income and its components in the statement of changes in stockholders' equity and requires an entity to present net income and other comprehensive income in one continuous statement or in two separate but consecutive statements.
