This excerpt taken from the USM DEF 14A filed Apr 25, 2007.
In March 2007, TDS announced that it was ceasing activity relating to its possible offer to acquire all of the Common Shares of U.S. Cellular that it did not already own. Early in 2005, TDS had disclosed that it
might make an offer to issue its Special Common Shares in exchange for such U.S. Cellular Common Shares.
In ceasing activity related to the acquisition, TDS made it clear that it would not commence or complete a possible transaction for U.S. Cellular shares on uneconomic terms. TDS believes that an acceptable exchange ratio would need to reflect appropriately the relative values of TDS and U.S. Cellular, recognizing that a substantial portion of the value of TDS is comprised of its ownership of U.S. Cellular. TDS believes that the relative prices of TDS Special Common Shares and U.S. Cellular Common Shares do not reflect this fact. As a legal matter, termination of consideration of a possible offer does not preclude TDS from acquiring the remaining Common Shares of U.S. Cellular in the future, should conditions change.
