SEC Filing Summary: United States Cellular Corporation (10-Q)

Business Context and Reporting Period

This Quarterly Report on Form 10-Q covers the period ended September 30, 2006. The registrant is United States Cellular Corporation (U.S. Cellular), a regional wireless operator and an 81.2%-owned subsidiary of Telephone and Data Systems, Inc. (TDS). The company operates in 241 wireless markets across the United States. The filing includes unaudited consolidated financial statements and a significant restatement of prior period financial data due to accounting errors identified in November 2006.

Key Financial Metrics (Nine Months Ended Sept 30, 2006)

Operating Margins: Operating income margin improved to 9.5% of service revenues in 2006 compared to 7.9% in 2005. The effective tax rate was 36.3% in 2006 versus 39.3% in 2005.

Material Changes vs. Prior Period

• Revenue Growth: Total operating revenues increased 14% year-over-year, driven by an 8% increase in the customer base (5.73 million customers) and a 4% increase in average monthly service revenue per customer ($46.92).
• Profitability: Net income increased 34% primarily due to higher operating income. Operating income rose 37% to $226.3 million.
• Restatement Impact: The company restated 2005 and prior period financials. For the nine months ended Sept 30, 2005, net income was adjusted upward by $1.5 million (from $92.3M to $93.8M) and diluted EPS by $0.01 (from $1.06 to $1.07) due to corrections in derivative accounting, asset retirement obligations, and income taxes.
• Capital Expenditures: Additions to property, plant, and equipment totaled $421.4 million, reflecting network expansion and cell site construction.

Guidance, Outlook, Risks, and Unusual Items

Guidance and Outlook:

• U.S. Cellular estimates full-year 2006 service revenues at approximately $3.2 billion.
• Estimated full-year 2006 operating income is projected between $275 million and $325 million.
• Estimated capital expenditures for 2006 range from $580 million to $610 million.

Unusual Items and Accounting Changes:

• Derivative Instruments: The company recognized a loss of $17.4 million in the first nine months of 2006 related to the fair value adjustment of derivative instruments (embedded collars in forward contracts for Vodafone securities). These are no longer designated as cash flow hedges, increasing earnings volatility.
• Stock-Based Compensation: Adoption of SFAS 123(R) on Jan 1, 2006, increased stock-based compensation expense by $10.4 million for the nine-month period compared to prior year methods.
• Asset Retirement Obligations (ARO): A revision in estimated cash flows for AROs increased the liability by $13.4 million in the first nine months of 2006.

Risks and Contingencies:

• Internal Controls: Management concluded that disclosure controls and procedures were not effective as of September 30, 2006, due to material weaknesses in accounting for income taxes, leases, forward contracts, and property, plant, and equipment. These weaknesses led to the restatement of prior financials.
• Credit Ratings: Standard & Poor's downgraded U.S. Cellular to BBB- (from A-) with a negative outlook. Moody's and Fitch also have negative watches. This may increase borrowing costs.
• Regulatory: The FCC denied U.S. Cellular's waiver for the 95% GPS-capable handset penetration requirement, referring the matter to the Enforcement Bureau for potential monetary forfeiture.
• Legal Proceedings: The company is subject to various legal proceedings and indemnification obligations, though no specific material loss amounts are currently estimable.

Investor Verification Checklist

• Restatement Details: Verify the specific impact of the restatement on the company's historical financial ratios and covenant compliance.
• Internal Control Remediation: Review the progress of the multi-year program to remediate material weaknesses in internal controls over financial reporting.
• Derivative Exposure: Assess the ongoing volatility risk associated with the $159.9 million forward contracts related to Vodafone securities maturing in May 2007.
• Regulatory Compliance: Monitor the outcome of the FCC's enforcement action regarding E-911 handset penetration rules.
• Capital Structure: Confirm the status of the $700 million revolving credit facility and the impact of recent credit rating downgrades on future financing costs.
• Barat Wireless Investment: Verify the status of the $127.2 million capital contributions to Barat Wireless for FCC Auction 66 licenses and the timeline for FCC award.
