These reclassifications present the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income – but only if the item reclassified is required under U.S. GAAP to be reclassified to net income int its entirety in the same reporting period. This standard update is effective for reporting periods beginning after December 15, 2012. The adoption of this accounting standard did not have an impact on our consolidated financial statements.
