Sky Brazil Functional Currency
Based on cumulatively significant changes in economic facts and circumstances, we have determined that we should consider the local Brazilian currency as the functional currency of Sky Brazil for purposes of financial statement translation beginning in the second quarter of 2009. The change in the functional currency for Sky Brazil to the local currency will result in an adjustment to recorded values for nonmonetary assets and liabilities and related deferred income tax assets and liabilities, with a corresponding adjustment to the "Cumulative translation adjustment", a component of "Accumulated other comprehensive loss" in stockholders' equity in the Consolidated Balance Sheets. In addition, as a result of this change in functional currency, changes in exchange rates will result in gains or losses in the Consolidated Statements of Operations related to the revaluation of U.S. dollar denominated monetary assets and liabilities held by Sky Brazil. We currently estimate a decrease of approximately $150 million to $200 million to previously reported values of non-monetary assets, an increase in our deferred income tax assets of approximately $55 million to $75 million, and an offsetting decrease of approximately $95 million to $125 million to the cumulative translation adjustment account in the second quarter of 2009 related to this change.
