In the future, Activision Blizzard may also consider whether other items should also be excluded in calculating the non-GAAP financial measures used by Activision Blizzard. Activision Blizzard's management believes that the presentation of these non-GAAP financial measures provides investors with additional useful information to measure Activision Blizzard's financial and operating performance. In particular, the measures facilitate comparison of operating performance between periods and help investors to better understand the operating results of Activision Blizzard by excluding certain items that may not be indicative of Activision Blizzard's core business, operating results or future outlook. Internally, Activision Blizzard's management uses these non-GAAP financial measures in assessing Activision Blizzard's operating results, and measuring compliance with the requirements of Activision Blizzard's debt financing agreements, as well as in planning and forecasting.
