Goodwill acquisitions in 2010 related primarily to the
acquisition of certain wireless properties from Verizon Wireless
(see Note 2). In 2011, we recorded a $2,745 impairment in
the Advertising Solutions segment, triggered by declining
revenues in our directory business and the directory industry
as a whole. Changes to goodwill during 2011 also included a
$1,927 reclassification of goodwill from the Advertising
Solutions segment to the Wireline segment to align certain
advertising operations with our U-verse business, which
operates the media platform for those advertising operations.
Changes to goodwill during 2010 included adjustments
totaling $(219) related to wireless business combinations and
$62 due primarily to adjustments relating to a wireline
business combination (see Note 2).
