Attachment A

PART III — NARRATIVE


As disclosed on a Current Report on Form 8-K dated November 9, 2005, United States Cellular Corporation ("U.S. Cellular") issued a news release announcing that it would restate financial results for the first and second interim periods of 2005, each of the five years ended December 31, 2004, and each of the interim periods of 2004 and 2003. Reference is made to U.S. Cellular's Form 8-K dated November 9, 2005 and the news release filed therewith for additional information. It is necessary for U.S. Cellular to finalize and complete the restatements before U.S. Cellular can file the Form 10-Q for the quarter ended September 30, 2005 because financial information to be included in the Form 10-Q depends on the results of the restatements of prior periods. The restatements cannot be completed by November 9, 2005 or the extension deadline of November 14, 2005 and, accordingly, the financial information required to be disclosed in the Form 10-Q cannot be prepared on a timely basis without unreasonable effort or expense.


The restatements and/or the failures to file the Form 10-Q for the quarter ended September 30, 2005 by the extended deadline have several consequences.


The restatements and the late filing of the Form 10-Q for the quarter ended September 30, 2005 will result in defaults under the revolving credit agreement between U.S. Cellular and certain lenders and under certain forward contracts between subsidiaries of U.S. Cellular and a counterparty. U.S. Cellular has not failed to make nor does it expect to fail to make any scheduled payment of principal or interest under such revolving credit agreements or forward contracts. U.S. Cellular has communicated with the agents for the lenders and the counterparty to obtain waivers from the lenders and the counterparty under such agreements. U.S. Cellular believes that the lenders and the counterparty will agree to waive any defaults that may occur as a result of the restatements and the late filing of the Form 10-Q however, such actions cannot be assured.


In addition, the late filing of the Form 10-Q may result in non-compliance under certain debt indentures. However, this non-compliance will not result in events of default unless and until written notice thereof is delivered by the trustee or sufficient holders of debt and, in any event, such events of default would be cured if U.S. Cellular files its Form 10-Q for the quarter ended September 30, 2005 within 90 days of any such notice. As a result, U.S. Cellular believes that it will be able to file the Form 10-Q in sufficient time to avoid any event of default maturing into a default under any indenture. U.S. Cellular has not failed to make nor does it expect to fail to make any scheduled payment of principal or interest under such indentures.


U.S. Cellular has notified the American Stock Exchange of the restatements and the expected delay in its filing of the Form 10-Q for the quarter ended September 30, 2005. U.S. Cellular expects to receive a notice of failure to satisfy listing requirements following such delay in filing. U.S. Cellular will disclose any such notice and the contents of such notice at such time. In such event, U.S. Cellular expects to restore compliance with such listing requirements when it files the restated financial statements for the periods noted herein and the Form 10-Q for the quarter ended September 30, 2005.



 


Attachment B

PART IV — OTHER INFORMATION


Item (3): Summary of the tentative unaudited results of operations for the quarterly and year to date periods ended September 30, 2005 and September 30, 2004, as restated, and explanation of any material anticipated changes between such periods:


        We are restating our financial results for the first and second interim periods of 2005, each of the five years ended December 31, 2004, and each of the interim periods of 2004 and 2003. As a result, you should not rely on our previously issued financial statements for these periods. This restatement is primarily related to U.S. Cellular's review of its accounting treatment for (1) Universal Service Fund contributions; (2) leases; (3) contract termination fees; (4) income tax accounting; and (5) other adjustments and accruals, including the recognition of income from certain investments accounted for under the equity method of accounting. We will file amendments as promptly as possible, but such filing is not expected to occur until mid-December, 2005.


        U.S. Cellular has not completed its assessment of the items described above. Based on preliminary findings; the adjustments are expected to result in increased (decreased) net income and diluted earnings per share as follows; however, there can be no assurance that final results will not differ materially from these preliminary findings.

  December 31, 2000   $193   $(3) to  1 $2.22   $(0.03) to  0.01  

        The guidance set forth in Auditing Standard No. 2 ("AS2") of the Public Company Accounting Oversight Board states that the restatement of previously-issued financial statements to reflect the correction of a misstatement should be regarded as at least a significant deficiency, and is a strong indicator of a material weakness in internal control over financial reporting. In connection with the expected filing of the 2004 Form 10-K/A, U.S. Cellular has concluded that a material weakness existed as of December 31, 2004, which precludes U.S. Cellular from concluding that its internal control over financial reporting was effective as of December 31, 2004. A material weakness is a control deficiency, or combination of control deficiencies, that results in a more than remote likelihood that a material misstatement of the interim or annual financial statements will not be detected. Therefore, U.S. Cellular's Management Report on Internal Control Over Financial Reporting, which was contained in Item 9A of the Form 10-K as of and for the year ended December 31, 2004 and which stated that U.S. Cellular's internal control over financial reporting was effective as of December 31, 2004, can no longer be relied upon and will be restated in connection with the filing of the Form 10-K/A. In such Form 10-K/A, (i) U.S. Cellular management will conclude that, as of December 31, 2004, U.S. Cellular did not maintain effective controls over the financial reporting process due to insufficient number of qualified personnel with the required proficiency to apply the company's accounting policies in accordance with U.S. GAAP and (ii) U.S. Cellular expects that



 


PricewaterhouseCoopers LLP, U.S. Cellular's independent registered public accounting firm, will reissue its report to state that U.S. Cellular did not maintain effective internal control over financial reporting as of December 31, 2004.


        Also, as a result of the accounting adjustments described above, U.S. Cellular is evaluating the effectiveness of internal control over financial reporting as of December 31, 2004 and September 30, 2005, including a review of controls in the following areas: (1) Universal Service Fund contributions; (2) leases; (3) contract termination fees; (4) income tax accounting; and (5) other adjustments and accruals, including the recognition of income from certain investments accounted for under the equity method of accounting.


        U.S. Cellular is reviewing the impact of these items individually and in the aggregate as part of an overall assessment. As a result of these adjustments and evaluations, U.S. Cellular believes it is possible that it may identify and report additional material weaknesses in its internal control over financial reporting.


        Procedures implemented to remediate the material weakness related to technical accounting expertise include:


  • Formation of Controller Review Committee comprised of TDS's Corporate Controller, and Assistant Corporate Controller, U.S. Cellular's Controller and Telecom's Chief Financial Officer. This committee meets regularly to discuss accounting treatment for current, unusual and nonrecurring matters.
  • Changes and additions in technical accounting personnel at TDS including hiring a Vice President and Assistant Corporate Controller and adding positions of Manager, External Reporting and Manager, Accounting and Reporting.
  • Changes and additions in technical accounting personnel at U.S. Cellular including hiring a Vice President and Controller, and a Director of Operations Accounting, and adding a position of Manager, Accounting Policy.

        Although management believes it has made substantial progress, additional efforts will be required to fully remediate the material weakness. Management is continuing to develop and implement additional remediation actions. Additional actions currently underway or planned include the recruiting of a Director of Accounting Policy and a Manager of Accounting Policy and Research at TDS, providing additional training for the accounting staff, incorporating additional analysis and review procedures into the accounting closing and financial reporting processes, strengthening controls related to review and approval of contracts, improving understandings with partners to ensure timely receipt of financial statements related to investments accounted for under the equity method, and other actions.


        U.S. Cellular's management and audit committee have discussed the matters in this Form 12b-25 with U.S. Cellular's independent registered public accounting firm, PricewaterhouseCoopers LLP.


        It is necessary for U.S. Cellular to finalize and complete the restatements before U.S. Cellular can file its Form 10-Q for the quarter ended September 30, 2005 because financial information to be included in such Form 10-Q depends on the results of such restatements of prior periods. Such Form 10-Q is due on November 9, 2005, but can be extended to November 14, 2005. It is not expected that the restatements will be completed by the extended deadline of November 14, 2005. Accordingly, U.S. Cellular expects that its Form 10-Q for the quarter ended September 30, 2005 will not be filed on a timely basis. U.S. Cellular expects to file the restatements and the Form 10-Q as soon as possible, but such filing is not expected to occur until mid-December 2005.


        The restatements and the late filing of the Form 10-Q for the quarter ended September 30, 2005 will result in defaults under the revolving credit agreement between U.S. Cellular and certain lenders and under certain forward contracts between subsidiaries of U.S. Cellular and a counterparty. Such debt related to the forward contracts totaled approximately $30 million. U.S. Cellular has not failed to make nor does it expect to fail to make any scheduled payment of principal or interest under such revolving credit agreements or forward contracts. U.S. Cellular has communicated with the agents for the lenders and the counterparty to obtain waivers from the lenders and the counterparty under such agreements. U.S. Cellular believes that the lenders and the counterparty will agree to waive any defaults that may occur as a result of the restatements and the late filing of the Form 10-Q, however, such actions cannot be assured.




 


        In addition, the late filing of the Form 10-Q may result in non-compliance under certain debt indentures. However, this non-compliance will not result in events of default unless and until written notice thereof is delivered by the trustee or sufficient holders of debt and, in any event, such events of default would be cured if U.S. Cellular files its Form 10-Q for the quarter ended September 30, 2005 within 90 days of any such notice. As a result, U.S. Cellular believes that it will be able to file the Form 10-Q in sufficient time to avoid any event of default maturing into a default under any indenture. U.S. Cellular has not failed to make nor does it expect to fail to make any scheduled payment of principal or interest under such indentures.


        U.S. Cellular has notified the American Stock Exchange of the restatements and the expected delay in its filing of the Form 10-Q for the quarter ended September 30, 2005. U.S. Cellular expects to receive a notice of failure to satisfy listing requirements from the American Stock Exchange following such delay in filing. U.S. Cellular will disclose any such notice and the contents of such notice at such time. In such event, U.S. Cellular expects to restore compliance with such listing requirements when it files the restated financial statements for the periods noted herein and the Form 10-Q for the quarter ended September 30, 2005.


        A summary of the tentative operating data and unaudited results of certain key components of the statement of operations for the third quarter and nine months of 2005, and for the third quarter and nine months of 2004, reflecting anticipated restatements, are included in the table below, however, there can be no assurance that final results will not differ materially from these preliminary findings.
