Presentation of Comprehensive Income

Effective January 1, 2012, we adopted, on a retrospective basis, the new accounting guidance on the presentation of comprehensive income. As a result of the adoption, we report total comprehensive income and the components of net income and other comprehensive income in two separate consecutive statements. Adoption of this guidance had no effect on our consolidated financial position, results of operations and cash flows.
