Until May 1, 2004, Qwest Corporation provided wireless services through its wholly owned subsidiary, Qwest Wireless LLC (“Qwest Wireless”). On May 1, 2004, we transferred ownership of Qwest Wireless to an affiliate. As a consequence, we no longer have wireless operations, and the results of operations and the financial position of Qwest Wireless have been reclassified in our consolidated financial statements to be included in discontinued operations. Amounts shown in this schedule have also been revised to conform to the current presentation of our consolidated financial statements.
