The Company was originally incorporated in California in 1979 and was reincorporated in Delaware in December 1992. In connection with the 2008 business combination by and among the Company (then known as Activision, Inc.), Vivendi S.A., and Vivendi Games, Inc., then an indirect wholly-owned subsidiary of Vivendi S.A., we were renamed Activision Blizzard, Inc.

Activision Publishing, Inc. (“Activision”) is a leading global developer and publisher of interactive software products and entertainment content, particularly for the console platform. Activision primarily delivers content through retail and digital channels, including full-game and in-game sales, as well as by licensing software to third-party or related-party companies that distribute Activision products. Activision develops, markets, and sells products primarily based on our internally developed intellectual properties, as well as some licensed properties. Activision’s key product franchise is Call of Duty^®, a first-person shooter for the console and PC platforms.

In 2010, Activision entered into an exclusive relationship with Bungie, Inc. (“Bungie”) to publish games in the Destiny franchise. Effective December 31, 2018, Activision and Bungie mutually agreed to terminate their publishing relationship related to the Destiny franchise. As part of this termination, Activision agreed to transfer its publishing rights for the Destiny franchise to Bungie in exchange for cash and Bungie’s assumption of on-going customer obligations of Activision. Activision no longer has any material rights or obligations related to the Destiny franchise.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim reporting. Accordingly, certain notes or other information that are normally required by U.S. GAAP have been condensed or omitted if they substantially duplicate the disclosures contained in our annual audited consolidated financial statements. Additionally, the year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. Accordingly, 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, 2018.

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. In the opinion of management, all adjustments considered necessary for the fair statement of our financial position and results of operations in accordance with U.S. GAAP (consisting of normal recurring adjustments) have been included in the accompanying unaudited condensed consolidated financial statements. Actual results could differ from these estimates and assumptions.

During the three months ended March 31, 2019, we identified an error principally related to the initial recognition of global intangible low-taxed income of foreign subsidiaries income taxes which should have been recorded in the three months and year ended December 31, 2018. Income tax expense for the three months and year ended December 31, 2018 should have been reduced by $35 million. This amount is not material to the consolidated financial statements for the year ended December 31, 2018, and we will revise our 2018 consolidated financial statements to correct this matter in our Annual Report on Form 10-K for the year ending December 31, 2019. Our condensed consolidated balance sheet as of December 31, 2018, as presented in this Form 10-Q, has been revised to reflect the correction of this error.

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.

The beginning and ending cash and cash equivalents and restricted cash reported within our condensed consolidated statement of cash flows included restricted cash amounts as follows (amounts in millions):
