Guidance, Outlook, and Risks

Management Guidance (Full Year 2006 Estimates)

• Service Revenues: Approximately $3.2 billion.
• Operating Income: $275 million to $325 million.
• Net Retail Customer Additions: 330,000 to 360,000.
• Capital Expenditures: Estimated between $580 million and $610 million.

Key Risks and Contingencies

• Internal Control Weaknesses: Management concluded that disclosure controls and procedures were not effective as of June 30, 2006, due to material weaknesses in accounting personnel, income tax accounting, and lease recording. These weaknesses led to prior restatements.
• Regulatory and Filing Issues: The company experienced late filings of its 2005 Form 10-K and 2006 Form 10-Qs, resulting in defaults under its revolving credit facility and forward contracts. Waivers were obtained from lenders and counterparties, contingent on timely future filings.
• IRS Audit: The IRS commenced an audit of the 2002-2004 consolidated federal tax returns of TDS (including U.S. Cellular) in June 2006.
• Market Risk: Significant exposure to marketable equity securities (Vodafone ADRs) and forward contracts. Credit ratings are under review for possible downgrade (Moody's Baa3, S&P A-).
• Future Obligations: Pending payment of approximately $47.2 million for spectrum licenses won by Barat Wireless in FCC Auction 66.

Investor Verification Checklist

• Internal Control Remediation: Verify the progress of the multi-year program to address material weaknesses in financial reporting and the hiring of qualified accounting personnel.
• Regulatory Compliance: Confirm that all required SEC filings (10-K, 10-Q) have been submitted to maintain waivers on credit facilities and forward contracts.
• Customer Acquisition Costs: Monitor the "Sales and marketing cost per gross customer addition" ($453 in H1 2006 vs. $425 in H1 2005) to ensure efficiency in growth strategies.
• Debt Covenants: Review the status of credit ratings and the impact of potential downgrades on borrowing costs and facility availability.
• Subsequent Events: Verify the receipt of proceeds from the Midwest Wireless sale (~$106 million) and the Vodafone Special Distribution (~$28.6 million) mentioned in subsequent events.
