Please see Facebook's Form 10-Q for the quarter ended September 30, 2012 for definitions of user activity used to determine the number of our MAUs, DAUs and
mobile MAUs. The number of MAUs, DAUs, and mobile MAUs do not include Instagram users unless such users would otherwise qualify as MAUs, DAUs, and
mobile MAUs based on activity that is shared back to Facebook.
In June 2012, we discovered an error in the algorithm we used to estimate the geographic location of our users that affected our attribution of certain user
locations for the first quarter of 2012. The first quarter of 2012 user metrics reflect a reclassification to more correctly attribute users by geographic region.

of the period and the last 27 days of the period, respectively, due to the algorithm error described in the MAU note on slide 3. These average numbers do not
meaningfully differ from the average numbers when calculated over a full month.

Revenue by user geography is geographically apportioned based on our estimation of the geographic location of our users when they perform a
revenue-generating activity. This allocation differs from our revenue by geography disclosure in our consolidated financial statements where
revenue is geographically apportioned based on the location of the advertiser or developer. The ARPU amount for US & Canada region in Q1
2012 reflects an adjustment based on the reclassification of certain users between geographical regions to more correctly attribute users by
geographic region.

Q2 and Q3 effective tax rates were influenced by significant share-based compensation expense resulting from our initial public
offering, a portion of which is not tax-deductible. A combination of tax benefits recorded in Q2 and tax provisions in Q1 and
Q3 result in an approximately 0% effective tax rate in the year-to-date period.

22. Limitations of Key Metrics
The numbers of our MAUs and DAUs and average revenue per user (ARPU) are calculated using internal
company data. While these numbers are based on what we believe to be reasonable estimates of our user
base for the applicable period of measurement, there are inherent challenges in measuring usage of our
products across large online and mobile populations around the world. For example, there may be
individuals who maintain one or more Facebook accounts in violation of our terms of service, despite our
efforts to detect and suppress such behavior. We estimate, for example, that “duplicate” accounts (an
account that a user maintains in addition to his or her principal account) may have represented
approximately 4.8% of our worldwide MAUs as of June 30, 2012. We also seek to identify “false” accounts,
which we divide into two categories: (1) user-misclassified accounts, where users have created personal
profiles for a business, organization, or non-human entity such as a pet (such entities are permitted on
Facebook using a Page rather than a personal profile under our terms of service); and (2) undesirable
accounts, which represent user profiles that we determine are intended to be used for purposes that violate
our terms of service, such as spamming. As of June 30, 2012, for example, we estimate user-misclassified
accounts may have represented approximately 2.4% of our worldwide MAUs and undesirable accounts
may have represented approximately 1.5% of our worldwide MAUs. We believe the percentage of
accounts that are duplicate or false is meaningfully lower in developed markets such as the United States
or Australia and higher in developing markets such as Indonesia and Turkey. However, these estimates
are based on an internal review of a limited sample of accounts and we apply significant judgment in
making this determination, such as identifying names that appear to be fake or other behavior that appears
inauthentic to the reviewers. As such, our estimation of duplicate or false accounts may not accurately
represent the actual number of such accounts. We are continually seeking to improve our ability to identify
duplicate or false accounts and estimate the total number of such accounts, and such estimates may be
affected by improvements or changes in our methodology.
22

23. Limitations of Key Metrics (continued)
Our metrics are also affected by applications on certain mobile devices that automatically contact our
servers for regular updates with no user action involved, and this activity can cause our system to count
the user associated with such a device as an active user on the day such contact occurs. For example, we
estimate that less than 5% of our estimated worldwide DAUs as of December 31, 2011 and 2010 resulted
from this type of automatic mobile activity, and that this type of activity had a substantially smaller effect on
our estimate of worldwide MAUs and mobile MAUs. The impact of this automatic activity on our metrics
varies by geography because mobile usage varies in different regions of the world. In addition, our data
regarding the geographic location of our users is estimated based on a number of factors, such as the
user’s IP address and self-disclosed location. These factors may not always accurately reflect the user’s
actual location. For example, a mobile-only user may appear to be accessing Facebook from the location
of the proxy server that the user connects to rather than from the user’s actual location. The
methodologies used to measure user metrics may also be susceptible to algorithm or other technical
errors. For example, in early June 2012, we discovered an error in the algorithm we use to estimate the
geographic location of our users that affected our attribution of certain user locations for the period ended
March 31, 2012. While this issue did not affect our overall worldwide MAU number, it did affect our
attribution of users to different geographic regions. We estimate that the number of MAUs as of March 31,
2012 for the United States and Canada region was overstated as a result of the error by approximately 3%
and these overstatements were offset by understatements in other regions. In addition, our estimates for
revenue by user location are also affected by these factors. We regularly review and may adjust our
processes for calculating these metrics to improve their accuracy. In addition, our MAU and DAU estimates
will differ from estimates published by third parties due to differences in methodology. For example, some
third parties are not able to accurately measure mobile users or do not count mobile users for certain user
groups or at all in their analyses.
