(1) In May 2012, we completed the sale of our Broadcast Servers and Storage business and our Media Services business. As a result, both businesses have been reported as discontinued operations in our consolidated financial statements. For all periods presented, our consolidated financial statements have been recast to reflect the presentation of discontinued operations.

(2) The sum of per share data may not agree to annual amounts due to rounding.
