Activision Blizzard Distribution Activision Blizzard Distribution (“Distribution”) consists of operations in Europe that provide warehousing, logistical and sales distribution services to third-party publishers of interactive entertainment software, our own publishing operations, and manufacturers of interactive entertainment hardware. Basis of Consolidation and Presentation Activision Blizzard prepared the accompanying unaudited condensed consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission for interim reporting. As permitted under those rules and regulations, certain notes or other information that are normally required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted if they substantially duplicate the disclosures contained in the annual audited consolidated financial statements. The year-end condensed balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2012, as amended. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for the fair statement of our financial position and results of operations in accordance with U.S. GAAP have been included in the accompanying unaudited condensed consolidated financial statements. The accompanying condensed consolidated financial statements include the accounts and operations of the Company. All intercompany accounts and transactions have been eliminated. The condensed consolidated financial statements have been prepared in conformity with U.S. GAAP. The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and assumptions. Certain reclassifications have been made to prior period amounts to conform to the current period presentation. The Company considers events or transactions that occur after the balance sheet date, but before the financial statements are issued, to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures. Results of Adjustments During the three months ended June 30, 2013, we identified through our internal processes that, in previous years, we erroneously under-accrued for certain indirect taxes for two countries in our Europe region. We performed an evaluation under SEC Staff Accounting Bulletin No. 108 and concluded the effect of this error was immaterial to prior years' financial statements as well as the projected full-year 2013 financial statements. As such, during the three months ended June 30, 2013, we recorded an adjustment in our condensed consolidated statements of operations which reduced “Total net revenues” by $8 million, “Investment and other income (expense), net” by $1 million, “Income before income tax expense” by $9 million, and “Net income” by $7 million. This adjustment reduced net revenues and income from operations before income tax expense by $8 million and $9 million, respectively, in each of our Blizzard segment, Europe region, and online subscriptions platform, as presented in footnote 7 of the notes to the condensed consolidated financial statements. The adjustment increased “Accrued expenses and other liabilities” on our condensed consolidated balance sheet by $9 million and represents a correction of an error. Operating cash flows will be impacted by $9 million in the period we settle the liability. The adjustment related to prior periods' net income as follows: (i) approximately $1 million for the quarter ended March 31, 2013; (ii) approximately $1 million for each quarter of 2012 (totaling approximately $4 million for the year ended December 31, 2012); (iii) approximately $2 million for the year ended December 31, 2011; and (iv) less than $1 million for the year ended December 31, 2010. Earnings per basic and diluted share were affected by less than $0.01 as a result of recording this adjustment. During the three months ended June 30, 2012, we identified through our internal processes that, in previous years, we erroneously over-recognized revenue for a country in our Europe region. We performed an evaluation under SEC Staff Accounting Bulletin No. 108 and concluded the effect of this error was immaterial to prior years' financial statements as well as the projected full-year 2012 financial statements. As such, during the three months ended June 30, 2012, we recorded an adjustment in our condensed consolidated statements of operations which reduced “Total net revenues” by $11 million and “Net income” by $8 million. This adjustment reduced net revenues and income from operations before income tax expense by $11 million in each of our Blizzard segment, Europe region, and online subscriptions platform, as presented in footnote 7 of the notes to the condensed consolidated financial statements. The adjustment increased “Deferred revenues” on our condensed consolidated balance sheet by $11 million and represents a correction of an error. There was no impact to operating cash flows. The adjustment related to prior periods' net income as follows: (i) approximately $1 million for the quarter ended March 31, 2012; (ii) less than $1 million for each quarter of 2011 (totaling approximately $3 million for the year ended December 31, 2011); (iii) approximately $2 million for the year ended December 31, 2010; and (iv) approximately $3 million for periods prior to the year ended December 31, 2010. Earnings per basic and diluted share were affected by less than $0.01 as a result of recording this adjustment.
