Notes to Financial Statements
Recent accounting pronouncements	In June 2011, the FASB issued a new accounting standard on the presentation of comprehensive income. The new standard requires the presentation 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 standard was effective for our quarter ended March 31, 2012. The adoption of this standard was limited to a change in the presentation of our results, which we have elected to include as separate Condensed Consolidated Statements of Comprehensive Income.
