U.S. Cellular and TDS Telecom Complete Sale of Wireless Assets to ALLTEL

CHICAGO, Dec. 1 /PRNewswire-FirstCall/ -- United States Cellular Corporation and TDS Telecom, subsidiaries of Telephone and Data Systems, Inc. , today announced that they have each completed the sale of certain wireless properties, as previously announced on Aug. 4, 2004, to ALLTEL Communications, Inc. of Little Rock, Ark. for a total of approximately $144 million in cash (approximately $112 million after taxes), including a working capital adjustment.

LeRoy T. Carlson, Jr., president and chief executive officer of TDS, commented, "These sales illustrate TDS's strategy of redeploying capital to more strategic parts of our businesses. U.S. Cellular proceeds will help defray costs related to building out new markets, while the TDS Telecom proceeds will help fund several of its technology trials."

John E. Rooney, president and chief executive officer of U.S. Cellular, said, "This transaction is a continuation of our strategy to exit markets that are not strategic to our long-term success. These properties, while valuable in their own right, do not complement the geographic footprint of the company nor strengthen its competitive position in our larger more well-established markets."

U.S. Cellular Assets

The U.S. Cellular assets sold to ALLTEL include operating markets and investment interests in several license areas. The operating markets are in one 25 megahertz (MHz) Metropolitan Statistical Area (MSA) license in Florida and one 25 MHz Rural Service Area (RSA) license in Ohio, representing an aggregate of 460,000 population equivalents and 35 cell sites. For the nine months ended Sept. 30, 2004, total revenue from these markets, which were included in U.S. Cellular's consolidated operations, was $15.3 million.

The U.S. Cellular investment interests are in five MSA licenses and two RSA licenses, representing an aggregate of 268,000 population equivalents in Ohio, North Carolina, Mississippi and Wisconsin. These assets are treated as investments; investment income from the assets is reported in "Investment Income" on U.S. Cellular's income statement.

U.S. Cellular received approximately $81 million in cash for the operating markets and investment interests.

TDS Telecom Assets

The TDS Telecom assets sold to ALLTEL include a majority interest in one RSA market in Georgia which has been operated by Alltel, representing 133,000 population equivalents, and an investment interest in one RSA market in Wisconsin, representing 5,000 population equivalents. Income from these assets is reported in "Other Income Net" on TDS's Income Statement. Proceeds were approximately $63 million in cash.
