Item 8.01.  Other Events

As previously disclosed, on November 6, 2012, United States Cellular Corporation (“U.S. Cellular”), a subsidiary of Telephone and Data Systems, Inc. (“TDS”), entered into a Purchase and Sale Agreement with subsidiaries of Sprint Nextel Corporation (“Sprint”).  Pursuant to the Purchase and Sale Agreement, on May 16, 2013, U.S. Cellular transferred customers and certain PCS license spectrum to Sprint in U.S. Cellular's Chicago, central Illinois, St. Louis and certain Indiana/Michigan/Ohio markets (“Divestiture Markets”) in consideration for $480 million in cash. The Purchase and Sale Agreement also contemplated certain other agreements, together with the Purchase and Sale Agreement collectively referred to as the “Divestiture Transaction.”  This transaction was reported on a Form 8-K dated November 6, 2012, which is incorporated by reference herein.

Also, as previously disclosed, on April 3, 2013, U.S. Cellular entered into an agreement relating to the Partnerships (as defined below) with Cellco Partnership d/b/a Verizon Wireless (“Verizon Wireless”).  U.S. Cellular holds a 60.00% interest in St. Lawrence Seaway RSA Cellular Partnership (“NY1”) and a 57.14% interest in New York RSA 2 Cellular Partnership (“NY2” and, together with NY1, the “Partnerships”).  The remaining interests are held by Verizon Wireless.  The Partnerships are operated by Verizon Wireless under the Verizon Wireless brand.  Prior to April 3, 2013, because U.S. Cellular owns a greater than 50% interest in each of these markets and based on U.S. Cellular’s rights under the Partnership Agreements, TDS consolidated the financial results of these markets in accordance with accounting principles generally accepted in the United States of America (“GAAP”).  The agreement amends the Partnership Agreements in several ways, which provide Verizon Wireless with substantive participating rights that allow Verizon Wireless to make decisions that are in the ordinary course of business of the Partnerships and which are significant to directing and executing the activities of the business.   Accordingly, as required by GAAP, TDS deconsolidated the Partnerships effective as of April 3, 2013 and thereafter reported them as equity method investments in its consolidated financial statements (the “Deconsolidation”).

The purpose of this Form 8-K is to file unaudited pro forma financial information for TDS for the three and six months ended June 30, 2013 that gives effect to the Divestiture Transaction and the Deconsolidation.

TDS previously filed a Form 8-K dated April 3, 2013 with pro forma financial information relating to the Deconsolidation as of and for the year ended December 31, 2012, which is incorporated by reference herein.  Subsequently on May 3, 2013, TDS filed a Form 8-K which updated that information and also added the Divestiture Transaction to the pro forma financial information, which is also incorporated by reference herein.  Because the Divestiture Transaction occurred on May 16, 2013, TDS is filing this Form 8-K to update such information through June 30, 2013.
