Daily Active Users (DAUs). We define a daily active user as a registered Facebook user who logged in
and visited Facebook through our website or a mobile device, or took an action to share content or activity
with his or her Facebook friends or connections via a third-party website that is integrated with Facebook,
on a given day. We view DAUs, and DAUs as a percentage of MAUs, as measures of user engagement.

Note: For non-worldwide DAU user numbers presented for the periods marked March 31, 2012 and June 30, 2012, the figures
represent an average of the first 25 days of the former period and the last 27 days of the latter period in order to avoid using data
subject to the algorithm error described in the MAU section above. These average numbers do not meaningfully differ from the
average numbers when calculated over a full month.
