SECURITIES AND EXCHANGE COMMISSION

Item 5. Other Events

        Telephone and Data Systems, Inc.("TDS") adopted Statement of Financial Accounting Standards ("SFAS") No. 143, "Accounting for Asset Retirement Obligations," effective January 1, 2003. An asset retirement obligation is the cost of closing facilities and removing assets, or performing other remediation to a property as required by contractual agreement. This accounting principle requires entities to record the estimated fair value of a legal liability for an asset retirement obligation in the period it is incurred. Adoption of this standard in the first quarter of 2003 required TDS and its subsidiaries to recognize estimated liabilities related to the future remediation of certain leased properties.

        During the fourth quarter of 2003, one of its subsidiaries, United States Cellular Corporation, revised the probability that its leased cell sites would require remediation and determined that an additional remediation liability was required. As a result of this change, TDS has restated its first-quarter 2003 financial statements to reflect a liability for future remediation of $54.4 million and a charge of $11.8 million, net of taxes and minority interest, as a cumulative effect of an accounting change. This cumulative effect reflects amounts that would have been charged to expense in prior years had SFAS No. 143 been effective for periods prior to January 1, 2003. This change also required additional charges to income for depreciation and non-cash accretion expense in each of the first three quarters of 2003. A summary of these changes is included on page 12 of the earnings release attached hereto as Exhibit 99.1. TDS will amend and re-file its Forms 10-Q for the quarters ended March 31, June 30 and September 30, 2003 to reflect these changes. The amendments are being filed in response to a routine comment letter received from the Division of Corporation Finance of the Securities and Exchange Commission.

        The Summary of Income Statement Effects of 2003 Accounting Changes on page 12 of the earnings release attached as Exhibit 99.1 is hereby incorporated by reference as part of this disclosure under Item 5 of Form 8-K.
