United States Cellular Corporation
Management's Discussion and Analysis of Financial Condition and Results of Operations

United States Cellular Corporation ("U.S. Cellular") owns, operates and invests in wireless markets throughout the United States. U.S. Cellular is an 83%-owned subsidiary of Telephone and Data Systems, Inc. ("TDS").

The following discussion and analysis should be read in conjunction with U.S. Cellular's audited consolidated financial statements and the description of U.S. Cellular's business included in Item 1 of the U.S. Cellular Annual Report on Form 10-K ("Form 10-K") for the year ended December 31, 2010.

OVERVIEW

The following is a summary of certain selected information contained in the comprehensive Management's Discussion and Analysis of Financial Condition and Results of Operations that follows. The overview does not contain all of the information that may be important. You should carefully read the entire Management's Discussion and Analysis of Financial Condition and Results of Operations and not rely solely on the overview.

U.S. Cellular provides wireless telecommunications services to approximately 6.1 million customers in five geographic market areas in 26 states. As of December 31, 2010, U.S. Cellular's average penetration rate in its consolidated operating markets was 13.0%. U.S. Cellular operates on a customer satisfaction strategy, striving to meet or exceed customer needs by providing a comprehensive range of wireless products and services, excellent customer support, and a high-quality network. U.S. Cellular's business development strategy is to acquire and operate controlling interests in wireless licenses in areas adjacent to or in proximity to its other wireless licenses, thereby building contiguous operating market areas. U.S. Cellular believes that operating in contiguous market areas will continue to provide it with certain economies in its capital and operating costs.

Financial and operating highlights in 2010 included the following:

•

Total customers were 6,072,000 at December 31, 2010, including 5,729,000 retail customers.

•

On October 1, 2010, U.S. Cellular launched The Belief Project which introduced several innovative service offerings including no contract after the first contract; simplified national rate plans; a loyalty rewards program; overage protection, caps and forgiveness; a phone replacement program; and discounts for paperless billing and automatic payment. As of December 31, 2010, nearly 1.2 million new and existing customers had adopted the new Belief Plans.

•

Retail customer net losses were 15,000 in 2010 compared to net additions of 37,000 in 2009. In the postpaid category, there was a net loss of 66,000 in 2010, compared to net additions of 62,000 in 2009. Prepaid net additions were 51,000 in 2010 compared to a net loss of 25,000 in 2009.

•

Postpaid customers comprised approximately 95% of U.S. Cellular's retail customers as of December 31, 2010. The postpaid churn rate improved to 1.5% in 2010 compared to 1.6% in 2009.

•

Postpaid customers on smartphone service plans increased to 17% as of December 31, 2010 compared to 7% as of December 31, 2009. In addition, smartphones represented 25% of all devices sold in 2010 compared to 10% in 2009.

•

Service revenues of $3,913.0 million decreased $14.1 million year-over-year, primarily due to a decrease in retail service revenues of $18.7 million (1%). Retail service revenues decreased due to a decline in the average number of customers of 55,000, partially offset by a slight increase in average monthly service revenue per customer.

•

Cash flows from operating activities were $874.3 million. At December 31, 2010, Cash and cash equivalents and Short-term investments totaled $441.0 million and there were no outstanding borrowings under the revolving credit facility.

•

Additions to Property, plant and equipment totaled $583.1 million, including expenditures to construct cell sites, increase capacity in existing cell sites and switches, expand mobile broadband services

based on third generation Evolution-Data Optimized technology ("3G") to additional markets, outfit new and remodel existing retail stores, develop new billing and other customer management related systems and platforms, and enhance existing office systems. Total cell sites in service increased 5% year-over-year to 7,645.

•

U.S. Cellular continued its efforts on a number of multi-year initiatives including the development of a Billing and Operational Support System ("B/OSS") with a new point-of-sale system to consolidate billing on one platform; an Electronic Data Warehouse/Customer Relationship Management System to collect and analyze information more efficiently and thereby build and improve customer relationships; and a new Internet/Web platform to enable customers to complete a wide range of transactions and to manage their accounts online.

•

In December 2010, U.S. Cellular entered into a new $300 million revolving credit agreement, which expires in December 2015, with certain lenders and other parties. As a result, U.S. Cellular's $300 million revolving credit agreement due to expire in June 2012 was terminated. U.S. Cellular entered into the new revolving credit agreement in order to obtain more favorable pricing, extended maturity and other terms and conditions.

•

Operating income decreased $125.5 million, or 39%, to $195.4 million in 2010 from $320.9 million in 2009. Factors in the decrease were lower service revenues as discussed above, together with higher costs of serving and retaining customers in an increasingly competitive industry, including costs of investments in multi-year initiatives.

•

Net income attributable to U.S. Cellular shareholders decreased $74.4 million, or 36%, to $132.3 million in 2010 compared to $206.7 million in 2009, primarily due to lower operating income. Basic earnings per share was $1.54 in 2010, which was $0.84 lower than in 2009, and Diluted earnings per share was $1.53, which was $0.84 lower than in 2009.

U.S. Cellular anticipates that future results will be affected by the following factors:

–

The Belief Project, which is intended to accelerate growth and have a positive impact on long-term profitability by increasing postpaid gross additions over the next several years and by contributing to incremental growth in average revenue per customer and improvement of U.S. Cellular's already low postpaid churn rate;



–

Continued uncertainty related to current economic conditions and their impact on customer purchasing and payment behaviors;



–

Relative ability to attract and retain customers in a competitive marketplace in a cost effective manner;



–

Increased competition in the wireless industry, including potential reductions in pricing for products and services overall and impacts associated with the expanding presence of carriers offering low-priced, unlimited prepaid service;



–

Potential increases in prepaid customers, which generally generate lower ARPU, as a percentage of U.S. Cellular's customer base in response to changes in customer preferences and industry dynamics;



–

Increasing penetration in the wireless industry, requiring U.S. Cellular to grow revenues primarily from selling additional products and services to its existing customers, increasing the number of multi-device users among its existing customers, increasing data products and services and attracting wireless customers switching from other wireless carriers rather than by adding customers that are new to wireless service;



–

Continued growth in revenues from data products and services and lower growth or declines in revenues from voice services;



–

Effects of industry consolidation on roaming revenues, service pricing and equipment pricing;



–

Costs of developing and enhancing office and customer support systems, including costs and risks associated with the completion and potential benefits of the multi-year initiatives described above;

Continued enhancements to U.S. Cellular's wireless networks;



–

Uncertainty related to the National Broadband Plan and other rulemaking by the Federal Communications Commission ("FCC"), including uncertainty relating to future eligible telecommunication carrier ("ETC") funding from the universal service fund ("USF"); and



–

Exclusive arrangements between manufacturers of wireless devices and other carriers that restrict U.S. Cellular's access to devices desired by customers.

Cash Flows and Investments

U.S. Cellular believes that cash and investments on hand, expected future cash flows from operating activities and sources of external financing provide substantial liquidity and financial flexibility and are sufficient to permit U.S. Cellular to finance its contractual obligations and anticipated capital expenditures for the foreseeable future. U.S. Cellular continues to seek to maintain a strong balance sheet and an investment grade credit rating.

See "Financial Resources" and "Liquidity and Capital Resources" below for additional information related to cash flows and investments, including information related to U.S. Cellular's new revolving credit agreement.

2011 Estimates

U.S. Cellular's estimates of full-year 2011 results are shown below. Such estimates represent U.S. Cellular's views as of the date of filing of U.S. Cellular's Form 10-K for the year ended December 31, 2010. Such forward-looking statements should not be assumed to be accurate as of any future date. U.S. Cellular undertakes no duty to update such information whether as a result of new information, future events or otherwise. There can be no assurance that final results will not differ materially from such estimated results.

Adjusted OIBDA is defined as operating income excluding the effects of: depreciation, amortization and accretion (OIBDA); the net gain or loss on asset disposals (if any); and the loss on impairment of assets (if any). This measure also may be commonly referred to by management as operating cash flow. This measure should not be confused with Cash flows from operating activities, which is a component of the Consolidated Statement of Cash Flows.

(2)

2010 Actual Results include losses on asset disposals of $10.7 million and no losses on impairment of assets. The 2011 Estimated Results include only the estimate for Depreciation, amortization and accretion expenses and losses on disposals of assets, and do not include any estimate for losses on impairment of assets (since these cannot be predicted).

(3)

This guidance is based on U.S. Cellular's current plans. New developments or changing competitive conditions in the wireless industry, such as the rate of deployment of 4G Long-term Evolution ("LTE") technology by other carriers, could affect U.S. Cellular's LTE deployment plans and, as a result, its capital expenditures and operating expenses.

U.S. Cellular management currently believes that the foregoing estimates represent a reasonable view of what is achievable considering actions that U.S. Cellular has taken and will be taking. However, the current general economic conditions in the markets served by U.S. Cellular have created a challenging

business environment that could continue to significantly impact actual results. U.S. Cellular expects to continue its focus on customer satisfaction by delivering a high quality network, attractively priced service plans, a broad line of wireless devices and other products, and outstanding customer service in its company-owned and agent retail stores and customer care centers. U.S. Cellular believes that future growth in its revenues will result primarily from selling additional products and services, including data products and services, to its existing customers, increasing the number of multi-device users among its existing customers, and attracting wireless users switching from other wireless carriers, rather than by adding users that are new to wireless service. U.S. Cellular is focusing on opportunities to increase revenues, pursuing cost reduction initiatives in various areas and implementing a number of initiatives to enable future growth. The initiatives are intended, among other things, to allow U.S. Cellular to accelerate its introduction of new products and services, better segment its customers for new services and retention, sell additional services such as data, expand its Internet sales and customer service capabilities, improve its prepaid products and services and reduce operational expenses over the long term.

RESULTS OF OPERATIONS

Following is a table of summarized operating data for U.S. Cellular's consolidated operations.

Components of Operating Income

Operating Revenues

Service revenues

Service revenues consist primarily of: (i) charges for access, airtime, roaming, recovery of regulatory costs and value-added services, including data products and services, provided to U.S. Cellular's retail customers and to end users through third-party resellers ("retail service"); (ii) charges to other wireless carriers whose customers use U.S. Cellular's wireless systems when roaming, including long-distance roaming ("inbound roaming"); and (iii) amounts received from the Federal USF.

Retail service revenues

The decrease in Retail service revenues in 2010 was primarily due to a decrease in U.S. Cellular's average customer base, partially offset by an increase in the average monthly retail service revenue per customer. The increase in 2009 was primarily due to an increase in average monthly retail service revenue per customer.

The average number of customers decreased to 6,121,000 in 2010 from 6,176,000 in 2009, driven by reductions in postpaid and reseller customers. The average number of customers in 2009 was relatively flat compared to 2008.

Table of Contents

Average monthly retail service revenue per customer increased slightly to $47.10 in 2010 from $46.93 in 2009, and in 2009 increased 1% from $ 46.45 in 2008. The 2010 and 2009 increases in average monthly retail service revenue per customer include the impact of a reduction in the number of reseller customers, who typically generate lower average monthly revenues.

U.S. Cellular expects continued pressure on revenues in the foreseeable future due to industry competition for customers and related effects on pricing of service plan offerings.

As discussed in the Overview section above, on October 1, 2010, U.S. Cellular introduced The Belief Project, which allows customers selecting Belief Plans to earn loyalty reward points. U.S. Cellular will account for loyalty reward points under the deferred revenue method. Under this method, U.S. Cellular will allocate a portion of the revenue billed to customers under the Belief Plans to the loyalty reward points. The revenue allocated to these points will initially be deferred on the Consolidated Balance Sheet to be recognized in future periods when the loyalty reward points are redeemed or used. Application of the deferred revenue method of accounting related to loyalty reward points resulted in deferred revenues of $7.1 million in 2010. This amount is included in the Consolidated Balance Sheet at December 31, 2010 in Customer deposits and deferred revenues.

Inbound roaming revenues

Inbound roaming revenues were essentially flat in 2010 compared to 2009 as an increase in revenues from data roaming offset a decline in voice roaming revenues.

In 2009, the decrease in Inbound roaming revenues was primarily due to the decline in roaming revenues from the combined entity of Verizon and Alltel. In January 2009, Verizon acquired Alltel. As a result of this transaction, the network footprints of Verizon and Alltel were combined. This has resulted in a decrease in inbound roaming revenues for U.S. Cellular, since the combined Verizon and Alltel entity has reduced its usage of U.S. Cellular's network in certain coverage areas that were used by Verizon and Alltel (as separate entities). U.S. Cellular anticipates that inbound roaming revenues will increase in 2011 compared to 2010 due to the growth of data usage and voice minutes from U.S. Cellular's roaming partners that will more than offset expected decreases in voice and data rates.

Other revenues

Other revenues increased by $4.0 million, or 2%, in 2010 compared to 2009. A decrease in ETC revenues was offset by increases in other revenues from tower and spectrum leases. The decrease in ETC revenues in 2010 was primarily the result of a retroactive adjustment made by the Universal Service Administrative Company that resulted in a reduction of revenues of $3.6 million. The increase in Other revenues in 2009 compared to 2008 was primarily due to an increase in amounts that were received from the USF for states in which U.S. Cellular has been designated as an ETC. U.S. Cellular was eligible to receive ETC funds in sixteen states in 2010, 2009 and 2008. ETC revenues recorded in 2010, 2009 and 2008 were $143.9 million, $150.7 million and $134.1 million, respectively.

In May 2008, the FCC adopted a state-by-state temporary cap to funding for competitive ETCs based on the funding level available as of March 31, 2008. The cap has had the effect of reducing the amount of support that U.S. Cellular would otherwise have been eligible to receive. The cap funding level is undergoing revision because of the time lag in the reporting of costs by local exchange carriers which, under the "identical support rule," provides the amount of per line support that wireless ETCs are entitled to receive. This revision may further reduce funding under the cap and may result in a recapture of some payments that U.S. Cellular has received in excess of the cap. In October 2010, the FCC proposed creating a $100-300 million Mobility Fund to subsidize on a one time basis new wireless broadband development in unserved areas, with reverse auctions to award subsidies to low bidders. On February 8, 2011, the FCC issued a notice of proposed rulemaking to consider reform of the USF program in response to the issuance of the National Broadband Plan in March 2010. Creation of the Mobility Fund and adoption of a USF reform proposal by the FCC to transition support from voice networks to broadband networks could have a significant and adverse impact on the amount of support, if any, wireless ETCs continue to receive. As a result, U.S. Cellular's ETC revenues may decline significantly in future periods.

Equipment sales revenues

Equipment sales revenues include revenues from sales of wireless devices (handsets, modems and tablets) and related accessories to both new and existing customers, as well as revenues from sales of wireless devices and accessories to agents. All equipment sales revenues are recorded net of rebates.

U.S. Cellular strives to offer a competitive line of quality wireless devices to both new and existing customers. U.S. Cellular's customer acquisition and retention efforts include offering new wireless devices to customers at discounted prices; in addition, customers on the new Belief Plans receive loyalty reward points that may be used to purchase a new wireless device or accelerate the timing of a customer's eligibility for a wireless device upgrade at promotional pricing. U.S. Cellular also continues to sell wireless devices to agents; this practice enables U.S. Cellular to provide better control over the quality of wireless devices sold to its customers, establish roaming preferences and earn quantity discounts from wireless device manufacturers which are passed along to agents. U.S. Cellular anticipates that it will continue to sell wireless devices to agents in the future.

The decrease in 2010 equipment sales revenues was driven by declines of 5% in total wireless devices sold and a 5% decrease in average revenue per wireless device sold. Average revenue per wireless device sold declined due to aggressive promotional pricing across all categories of wireless devices. The decrease in 2009 equipment sales revenues was driven by a decline of 8% in average revenue per wireless device sold due to aggressive promotional pricing across all categories of wireless devices, partially offset by an increase in the total number of wireless devices sold.

Operating Expenses

System operations expenses (excluding Depreciation, amortization and accretion)

System operations expenses (excluding Depreciation, amortization and accretion) include charges from telecommunications service providers for U.S. Cellular's customers' use of their facilities, costs related to local interconnection to the wireline network, charges for maintenance of U.S. Cellular's network, long-distance charges, outbound roaming expenses and payments to third-party data product and platform developers.

Key components of the overall increases in system operations expenses were as follows:

•

Maintenance, utility and cell site expenses increased $25.2 million, or 8%, in 2010 and $21.6 million, or 7%, in 2009, driven primarily by increases in the number of cell sites within U.S. Cellular's network. The number of cell sites totaled 7,645 in 2010 and 7,279 in 2009, as U.S. Cellular continued to expand and enhance coverage in its existing markets. The increases in expenses were also due to an increase in software maintenance costs to support rapidly growing data needs.

•

Expenses incurred when U.S. Cellular's customers used other carriers' networks while roaming increased $2.6 million, or 1%, in 2010 and $4.3 million, or 2%, in 2009. The increases were primarily due to increases from data roaming offset by a decline in voice roaming expenses.

•

Customer usage expenses increased by $24.2 million, or 9%, in 2010, primarily due to an increase in data usage. In 2009, the cost of network usage on U.S. Cellular's systems decreased $6.1 million, or 2%, primarily due to reduced interconnection costs, which reflected a change in estimate of these costs during the fourth quarter (as disclosed in Note (4) to Consolidated Quarterly Information (Unaudited) below), partially offset by an increase in data usage.

U.S. Cellular expects total system operations expenses to increase on a year-over-year basis in the foreseeable future to support the continued growth in cell sites and other network facilities as it continues to add capacity, enhance quality and deploy new technologies as well as to support increases in total customer usage, particularly data usage.

Cost of equipment sold

Cost of equipment sold remained relatively flat in 2010 compared to 2009. A decline in total wireless devices sold of 5% was offset by a 5% increase in the average cost per wireless device sold due to a shift in the mix of sales to wireless devices with expanded capabilities, such as smartphones.

Cost of equipment sold remained relatively flat in 2009 compared to 2008. A reduction in the average cost per wireless device sold, reflecting lower overall purchase costs, was offset by an increase in the total number of wireless devices sold.

U.S. Cellular's loss on equipment, defined as equipment sales revenues less cost of equipment sold, was $478.3 million, $456.2 million and $440.5 million for 2010, 2009 and 2008, respectively. U.S. Cellular expects loss on equipment to continue to be a significant cost in the foreseeable future as wireless carriers continue to use device availability and pricing as a means of competitive differentiation. In addition, U.S. Cellular expects increasing sales of data centric wireless devices such as smartphones and tablets to result in higher equipment subsidies over time; these devices generally have higher purchase costs which cannot be recovered through proportionately higher selling prices to customers.

Selling, general and administrative expenses

Selling, general and administrative expenses include salaries, commissions and expenses of field sales and retail personnel and facilities; telesales department salaries and expenses; agent commissions and related expenses; corporate marketing and merchandise management; and advertising expenses. Selling, general and administrative expenses also include bad debts expense, costs of operating customer care centers and corporate expenses.

Key components of the net increases in Selling, general and administrative expenses were as follows:

2010—

•

Selling and marketing expenses increased by $9.3 million, or 1%, primarily due to higher sales related expenses and higher advertising expenses due to an increase in media purchases, partially offset by lower commissions expense reflecting fewer eligible customer additions. In 2010, media purchases included advertising expenses related to the launch of The Belief Project.

•

General and administrative expenses increased $39.9 million, or 4%, due to higher costs related to investments in multi-year initiatives for business support systems as described in the Overview section; and higher USF contributions (most of the USF contribution expense is offset by revenues for amounts passed through to customers). These increases were partially offset by a reduction in bad debts expense.

2009—

•

General and administrative expenses increased $52.4 million, or 6%, primarily due to higher bad debts expense as a result of higher bad debt write-offs and a change in estimate during the fourth quarter (as disclosed in Note (4) to Consolidated Quarterly Information (Unaudited) below); higher employee related expenses; costs of the Battery Swap program; and investments in multi-year initiatives as described in the Overview section. Partially offsetting these and other increases were lower USF contributions (most of the USF contribution expenses are offset by revenues for amounts passed through to customers).

•

Advertising expenses decreased $20.9 million, or 8%. Advertising expenses in 2008 included expenditures related to the launch in June 2008 of a new branding campaign, Believe in Something Better^SM.

•

Other selling and marketing expenses increased by $9.4 million, or 2%, reflecting higher commissions due to a greater number of retail sales and renewals.

U.S. Cellular expects Selling, general and administrative expenses to increase on a year-over-year basis driven primarily by increases in expenses associated with acquiring, serving and retaining customers, as well as costs related to its multi-year initiatives.

Depreciation, amortization and accretion

Depreciation, amortization and accretion remained relatively flat in 2010, 2009 and 2008.

See "Financial Resources" and "Liquidity and Capital Resources" for a discussion of U.S. Cellular's capital expenditures.

Loss on impairment of intangible assets

There was no impairment of intangible assets in 2010.

In 2009 and 2008, U.S. Cellular recognized impairment losses on licenses as indicated in the table below. The 2009 impairment loss was incurred in connection with the annual impairment assessment of licenses and goodwill performed during the fourth quarter of 2009. The 2008 impairment loss was attributable to the deterioration in the credit and financial markets and the accelerated decline in the overall economy in the fourth quarter of 2008. These factors impacted U.S. Cellular's calculation of the estimated fair value of licenses in the fourth quarter of 2008 through the use of a higher discount rate when projecting future cash flows and lower than previously projected earnings in the wireless industry.

The impacts of impairment losses related to licenses were as follows:

Components of Other Income (Expense)

Equity in earnings of unconsolidated entities

Equity in earnings of unconsolidated entities represents U.S. Cellular's share of net income from entities accounted for by the equity method of accounting. U.S. Cellular generally follows the equity method of accounting for unconsolidated entities in which its ownership interest is less than or equal to 50% but equals or exceeds 20% for corporations and 3% for partnerships and limited liability companies.

U.S. Cellular's investment in the Los Angeles SMSA Limited Partnership ("LA Partnership") contributed $64.8 million, $64.7 million and $66.1 million to Equity in earnings of unconsolidated entities in 2010, 2009 and 2008, respectively. U.S. Cellular received cash distributions from the LA Partnership of $66.0 million in each of 2010, 2009 and 2008.

Gain on disposition of investments

Gain on disposition of investments in 2008 related to the exchange of Rural Cellular Corporation ("RCC") shares for cash in conjunction with Verizon's acquisition of RCC.

Interest expense

Interest expense decreased in 2010 compared to 2009 primarily due to the redemption of U.S. Cellular's $130.0 million, 8.75% senior notes in December 2009.

Income tax expense

The effective tax rates on Income before income taxes ("pre-tax income") for 2010, 2009 and 2008 were 33.8%, 33.7% and 11.4%, respectively. The following significant discrete and other items impacted income tax expense for these years:

2010—Includes a tax benefit of $7.9 million resulting from favorable settlements of state income tax audits.

2009—Includes tax benefits of $7.7 million and $7.2 million resulting from a state tax law change and the release of state valuation allowances, respectively.

2008—Includes tax benefits of $7.6 million and $2.5 million resulting from a change in filing positions in certain states and the resolution of a prior period tax issue, respectively. The percentage impact of these benefits was magnified due to the 2008 Loss on impairment of intangible assets of $386.7 million, which decreased pre-tax income.

See Note 4—Income Taxes in the Notes to Consolidated Financial Statements for a discussion of income tax expense and the overall effective tax rate on Income before income taxes.

INFLATION

Management believes that inflation affects U.S. Cellular's business to no greater or lesser extent than the general economy.

RECENT ACCOUNTING PRONOUNCEMENTS

In general, recent accounting pronouncements did not have and are not expected to have a significant effect on U.S. Cellular's financial condition and results of operations.

See Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements for information on recent accounting pronouncements.

FINANCIAL RESOURCES

U.S. Cellular operates a capital- and marketing-intensive business. U.S. Cellular utilizes cash from its operating activities, cash proceeds from divestitures, short-term credit facilities and long-term debt financing to fund its acquisitions (including licenses), construction costs, operating expenses and Common Share repurchases. Cash flows may fluctuate from quarter to quarter and year to year due to seasonality, the timing of acquisitions, capital expenditures and other factors. The table below and the following discussion in this Financial Resources section summarize U.S. Cellular's cash flow activities in 2010, 2009 and 2008.

U.S. Cellular's financial condition and results of operations because it highlights certain key cash and non-cash items and their impacts on cash flows from operating activities:

Cash flows from operating activities in 2010 were $874.3 million, a decrease of $7.5 million from 2009. Significant changes included the following:

•

Adjusted OIBDA, as shown in the table above, decreased by $137.5 million primarily due to a decrease in operating income. See discussion in the "Results of Operations" for factors that affected operating income.

•

Changes in inventory provided $40.3 million in 2010 and required $36.0 million in 2009, resulting in a $76.3 million year-over-year increase in cash flows. Inventory units on hand were lower in 2010 than 2009 reflecting differences in purchases and actual versus expected sales in the respective periods.

•

Changes in accounts payable required $18.6 million in 2010 and provided $52.6 million in 2009 causing a year-over-year decrease in cash flows of $71.2 million. Changes in accounts payable were driven primarily by payment timing differences.

•

A $16.2 million increase in income tax payments. Income tax payments, net of refunds, were $53.1 million and $36.9 million in 2010 and 2009, respectively.

•

The change in Accrued taxes during 2010 includes an outflow of approximately $25 million related to sales tax payments made during 2010 related to prior years. U.S. Cellular had accrued these sales taxes at December 31, 2009. The 2009 period does not include a similar outflow related to the retroactive payment of sales taxes.

•

Changes in other assets and liabilities provided $79.5 million in 2010 and required $51.1 million in 2009, resulting in a $130.7 million year-over-year increase in cash flows. In 2009, a $34.0 million deposit was paid to TDS for U.S. Cellular's proportionate share of a deposit TDS made to the Internal Revenue Service ("IRS") to eliminate any potential interest due to the IRS subsequent to the date of the deposit. In 2010, after closure of the IRS audit for the tax years 2002 through 2005, the IRS returned TDS' $38.0 million deposit, of which TDS returned $34.0 million to U.S. Cellular, representing U.S. Cellular's proportionate share. This $34.0 million was included in Change in other assets and liabilities in 2010, as a cash inflow, and in 2009, as a cash outflow. This activity resulted in a year-over year increase in cash flows of $68.0 million from 2009 to 2010. In addition to this $68.0 million change, changes in prepaid expenses, other current liabilities and amounts due to agents were the primary cause of the remaining $62.7 million year-over-year change in other assets and liabilities.

•

An $18.8 million decrease in interest payments. Interest payments were $59.0 million and $77.9 million in 2010 and 2009, respectively.

•

Other significant increases in cash flows include Distributions from unconsolidated entities ($9.3 million increased cash inflow year-over-year) and Changes in customer deposits and deferred revenues ($16.1 million increased cash inflow year-over-year, which includes $7.1 million of deferred revenues related to loyalty reward points).

Cash flows from operating activities in 2009 were $881.8 million, a decrease of $41.0 million from 2008. Significant changes included the following:

•

Adjusted OIBDA, as shown in the table above, decreased by $88.9 million.

•

Changes in accounts receivable, net of bad debts expense, required $6.7 million in 2009 and provided $4.1 million in 2008, resulting in a $10.8 million decrease in cash flows. This change was driven primarily by service credit promotions offered to customers in the fourth quarter of 2008.

•

Changes in inventory required $36.0 million in 2009 and $15.6 million in 2008. The $20.4 million decrease in cash flows was attributed to a higher volume of wireless devices on hand as well as the continued mix shift towards higher-cost premium and smartphone devices.

•

Changes in accounts payable, customer deposits and deferred revenues provided $42.7 million in 2009 and $3.2 million in 2008. The resultant $39.5 million increase in cash flows was driven primarily by timing differences in payments of accounts payable and lower deposit requirements for new customers in 2009.

•

Income tax payments, net of refunds, in 2009 and 2008 were $36.9 million and $116.5 million, respectively, resulting in an increase in cash flows of $79.6 million. The decrease in payments from 2008 to 2009 was due to a year-over-year decrease in forecasted income and an overpayment of income taxes in 2008.

•

In 2009, a $34.0 million deposit was paid to TDS for U.S. Cellular's proportionate share of a deposit TDS made to the IRS. This deposit was recorded in Change in other assets and liabilities in the Consolidated Statement of Cash Flows in 2009.

Cash Flows from Investing Activities

U.S. Cellular makes substantial investments to construct and upgrade modern high-quality wireless communications networks and facilities as a basis for creating long-term value for shareholders. In recent years, rapid changes in technology and new opportunities have required substantial investments in potentially revenue-enhancing and cost-reducing upgrades of U.S. Cellular's networks. Cash flows used for investing activities also represent cash required for the acquisition of wireless properties or licenses. Proceeds from exchanges and divestiture transactions have provided funds in recent years which have partially offset the cash requirements for investing activities; however, such sources cannot be relied upon to provide continuing or regular sources of financing.

The primary purpose of U.S. Cellular's construction and expansion expenditures is to provide for customer and usage growth, to upgrade service and to take advantage of service-enhancing and cost-reducing technological developments in order to maintain competitive services.

Cash used for property, plant and equipment and system development expenditures totaled $583.1 million in 2010, $546.8 million in 2009 and $585.6 million in 2008. These expenditures were made to construct new cell sites, increase capacity in existing cell sites and switches, upgrade technology including the overlay of 3G technology, develop new and enhance existing office systems, and construct new and remodel existing retail stores.

Table of Contents

Acquisitions required cash payments of $17.1 million in 2010, $16.0 million in 2009 and $341.7 million in 2008, as summarized below:

In 2010, U.S. Cellular invested $250.3 million in U.S. treasuries and corporate notes with maturities greater than three months from the acquisition date. U.S. Cellular realized cash proceeds of $60.3 million in 2010 related to the maturities of its investments in U.S. treasuries, corporate notes and CDs.

In 2008, U.S. Cellular realized cash proceeds of $16.7 million from the disposition of Rural Cellular Corporation ("RCC") Common Shares in conjunction with Verizon Wireless' acquisition of RCC.

Cash Flows from Financing Activities

Cash flows from financing activities primarily reflect changes in short-term and long-term debt balances, distributions to noncontrolling interests, cash used to repurchase Common Shares and cash proceeds from re-issuance of Common Shares pursuant to stock-based compensation plans. U.S. Cellular has used short-term debt to finance acquisitions, for general corporate purposes and to repurchase Common Shares. Internally generated funds as well as proceeds from the sale of non-strategic wireless and other investments, from time to time, have been used to reduce short-term debt.

There were no short-term borrowings or repayments during 2010 or 2009. Cash received from short-term borrowings under U.S. Cellular's revolving credit facility provided $100.0 million in 2008, while repayments required $100.0 million in 2008.

In 2009, U.S. Cellular redeemed its outstanding 8.75% senior notes for their principal amount of $130.0 million and retired its 9% installment notes payable in the amount of $10.0 million. There were no redemptions of long-term debt in 2010 or 2008.

U.S. Cellular repurchased Common Shares for $52.8 million, $33.6 million and $32.9 million in 2010, 2009 and 2008, respectively. U.S. Cellular also received $4.6 million in 2008 from an investment banking firm for the final settlement of Accelerated Share Repurchases ("ASR") made in 2007. See Note 14—Common Shareholders' Equity in the Notes to Consolidated Financial Statements for additional information related to these transactions.

Free Cash Flow

The following table presents Free cash flow. U.S. Cellular believes that Free cash flow as reported by U.S. Cellular may be useful to investors and other users of its financial information in evaluating the amount of cash generated by business operations, after capital expenditures.

See Cash flows from Operating Activities and Cash flows from Investing Activities for details on the changes to the components of Free cash flow.

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 2010, U.S. Cellular had Cash and cash equivalents, Short-term investments and Long-term investments totaling $487.0 million, as discussed in more detail below. U.S. Cellular believes that existing cash and investments balances, expected cash flows from operating activities and funds available under its revolving credit facility provide substantial liquidity and financial flexibility for U.S. Cellular to meet its normal financing needs (including working capital, construction and development expenditures, and share repurchases under its approved program) for the foreseeable future. In addition, U.S. Cellular may have access to public and private capital markets to help meet its financing needs.

Consumer spending significantly impacts U.S. Cellular's operations and performance. Factors that influence levels of consumer spending include: unemployment rates, increases in fuel and other energy costs, conditions in residential real estate and mortgage markets, labor and health care costs, access to credit, consumer confidence and other macroeconomic factors. Changes in these and other economic factors could have a material adverse effect on demand for U.S. Cellular's products and services and on U.S. Cellular's financial condition and results of operations.

U.S. Cellular cannot provide assurances that circumstances that could have a material adverse effect on its liquidity or capital resources will not occur. Economic conditions, changes in financial markets or other factors could restrict U.S. Cellular's liquidity and availability of financing on terms and prices acceptable to U.S. Cellular, which could require U.S. Cellular to reduce its construction, development, acquisition or share repurchase programs. Such reductions could have a material adverse effect on U.S. Cellular's business, financial condition or results of operations.

Cash and Cash Equivalents

At December 31, 2010, U.S. Cellular had $294.4 million in cash and cash equivalents, which included cash and short-term, highly liquid investments with original maturities of three months or less. The primary objective of U.S. Cellular's cash and cash equivalents investment activities is to preserve principal. At December 31, 2010, the majority of U.S. Cellular's cash and cash equivalents was held in money market funds that invest exclusively in U.S. Treasury securities or in repurchase agreements fully collateralized by such obligations. U.S. Cellular monitors the financial viability of the money market funds and direct investments in which it invests and believes that the credit risk associated with these investments is low.

Short-term and Long-term Investments

At December 31, 2010, U.S. Cellular had $146.6 million in Short-term investments and $46.0 million in Long-term investments. Short-term and Long-term investments consist of certificates of deposit (short-term only), U.S. treasuries and corporate notes, all of which are designated as held-to-maturity

16

Table of Contents

investments, and are recorded at amortized cost in the Consolidated Balance Sheet. The corporate notes are guaranteed by the Federal Deposit Insurance Corporation. For these investments, U.S. Cellular's objective is to earn a higher rate of return on funds that are not anticipated to be required to meet liquidity needs in the near term, while maintaining a low level of investment risk. See Note 3—Fair Value Measurements in the Notes to Consolidated Financial Statements for additional details on Short-term and Long-term investments.

Revolving Credit Facility

U.S. Cellular has a revolving credit facility available for general corporate purposes. On December 17, 2010, U.S. Cellular entered into a new $300 million revolving credit agreement with certain lenders and other parties. Amounts under the new revolving credit facility may be borrowed, repaid and reborrowed from time to time until maturity in December 2015. At December 31, 2010, there were no outstanding borrowings and $0.2 million of outstanding letters of credit, leaving $299.8 million available for use. In connection with U.S. Cellular's new revolving credit facility, TDS and U.S. Cellular entered into a subordination agreement dated December 17, 2010 together with the administrative agent for the lenders under U.S. Cellular's new revolving credit facility. At December 31, 2010, no U.S. Cellular debt was subordinated pursuant to this subordination agreement.

U.S. Cellular's interest cost on its new revolving credit facility is subject to increase if its current credit rating from nationally recognized credit rating agencies is lowered, and is subject to decrease if the rating is raised. The credit facility would not cease to be available nor would the maturity date accelerate solely as a result of a downgrade in U.S. Cellular's credit rating. However, a downgrade in U.S. Cellular's credit rating could adversely affect its ability to renew the credit facility or obtain access to other credit facilities in the future.

During 2010, U.S. Cellular's credit rating was downgraded from BBB+ to BBB by Fitch Ratings. As of December 31, 2010, U.S. Cellular's credit ratings from the nationally recognized credit rating agencies including Fitch Ratings remained at investment grade.

The continued availability of the new revolving credit facility requires U.S. Cellular to comply with certain negative and affirmative covenants, maintain certain financial ratios and make representations regarding certain matters at the time of each borrowing. The covenants also prescribe certain terms associated with intercompany loans from TDS or TDS subsidiaries to U.S. Cellular or U.S. Cellular subsidiaries. U.S. Cellular believes it was in compliance as of December 31, 2010 with all of the covenants and requirements set forth in its new revolving credit facility. There were no intercompany loans at December 31, 2010 or 2009.

Long-Term Financing

U.S. Cellular had the following public debt outstanding as of December 31, 2010:

•

$544,000,000 aggregate principal amount of 6.7% senior notes due December 15, 2033. U.S. Cellular may redeem such notes, in whole or in part, at any time prior to maturity at a redemption price equal to the greater of (a) 100% of the principal amount of such notes, plus accrued and unpaid interest, or (b) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date on a semi-annual basis at the Treasury Rate plus 30 basis points.

•

$330,000,000 aggregate principal amount of 7.5% senior notes due June 15, 2034. U.S. Cellular may redeem the notes, in whole or in part, at any time on or after June 17, 2009, at a redemption price equal to 100% of the principal amount redeemed plus accrued and unpaid interest.

U.S. Cellular's long-term debt indenture does not contain any provisions resulting in acceleration of the maturities of outstanding debt in the event of a change in U.S. Cellular's credit rating. However, a downgrade in U.S. Cellular's credit rating could adversely affect its ability to obtain long-term debt financing in the future. U.S. Cellular believes it was in compliance as of December 31, 2010 with all covenants and other requirements set forth in its long-term debt indenture. U.S. Cellular has not failed to

Table of Contents

make nor does it expect to fail to make any scheduled payment of principal or interest under such indenture.

The long-term debt principal payments due for the next five years represent less than 1% of the total long-term debt obligation at December 31, 2010. Refer to Market Risk—Long-Term Debt for additional information regarding required principal payments and the weighted average interest rates related to U.S. Cellular's long-term debt.

U.S. Cellular, at its discretion, may from time to time seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for other securities, in open market purchases, privately negotiated transactions, tender offers, exchange offers or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

U.S. Cellular has an effective shelf registration statement on Form S-3 that it can use to issue senior debt securities that can be used for general corporate purposes, including financing the redemption of any of the above existing debt. The U.S. Cellular shelf registration statement permits U.S. Cellular to issue at any time and from time to time, senior debt securities in one or more offerings up to an aggregate principal amount of $500,000,000. The ability of U.S. Cellular to complete an offering pursuant to such shelf registration statement is subject to market conditions and other factors at the time.

Capital Expenditures

U.S. Cellular's capital expenditures for 2011 are expected to be approximately $650 million. These expenditures are expected to be for the following general purposes:

•

Expand and enhance U.S. Cellular's network coverage in its service areas;

•

Provide additional capacity to accommodate increased network usage by current customers;

•

Deploy LTE technology in certain markets;

•

Enhance U.S. Cellular's retail store network;

•

Develop and enhance office systems; and

•

Develop new billing and other customer management related systems and platforms.

U.S. Cellular plans to finance its capital expenditures program for 2011 using cash flows from operating activities, existing cash balances, short-term investments and, if necessary, short-term debt.

Acquisitions, Divestitures and Exchanges

U.S. Cellular assesses its existing wireless interests on an ongoing basis with a goal of improving the competitiveness of its operations and maximizing its long-term return on investment. As part of this strategy, U.S. Cellular reviews attractive opportunities to acquire additional wireless operating markets and wireless spectrum. In addition, U.S. Cellular may seek to divest outright or include in exchanges for other wireless interests those wireless interests that are not strategic to its long-term success. U.S. Cellular also may be engaged from time to time in negotiations relating to the acquisition, divestiture or exchange of companies, strategic properties or wireless spectrum. In general, U.S. Cellular may not disclose such transactions until there is a definitive agreement. See Note 7—Acquisitions, Divestitures and Exchanges in the Notes to Consolidated Financial Statements for details on significant transactions in 2010, 2009 and 2008.

Variable Interest Entities

U.S. Cellular consolidates certain entities because they are "variable interest entities" under accounting principles generally accepted in the United States of America ("GAAP"). See Note 5—Variable Interest Entities in the Notes to Consolidated Financial Statements for the details of these variable interest entities. U.S. Cellular may elect to make additional capital contributions and/or advances to these variable interest entities in future periods in order to fund their operations.

Common Share Repurchase Program

U.S. Cellular has repurchased and expects to continue to repurchase its Common Shares subject to the repurchase program. For additional information related to the current repurchase authorization and repurchases made during 2010, 2009 and 2008, see Note 14—Common Shareholders' Equity in the Notes to Consolidated Financial Statements.

Contractual and Other Obligations

At December 31, 2010, the resources required for contractual obligations were as follows:

The table above excludes liabilities related to "unrecognized tax benefits" as defined by GAAP because U.S. Cellular is unable to predict the period of settlement of such liabilities. Such unrecognized tax benefits were $32.5 million at December 31, 2010. See Note 4—Income Taxes in the Notes to Consolidated Financial Statements for additional information on unrecognized tax benefits.

Off-Balance Sheet Arrangements

U.S. Cellular has no transactions, agreements or other contractual arrangements with unconsolidated entities involving "off-balance sheet arrangements," as defined by Securities and Exchange Commission rules, that had or are reasonably likely to have a material current or future effect on its financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

U.S. Cellular prepares its consolidated financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP"). U.S. Cellular's significant accounting policies are discussed in detail in Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements.

Management believes the application of the following critical accounting policies and the estimates required by such application reflect its most significant judgments and estimates used in the preparation of U.S. Cellular's consolidated financial statements. Management has discussed the development and selection of each of the following accounting policies and related estimates and disclosures with the Audit Committee of U.S. Cellular's Board of Directors.

Goodwill and Licenses

See the Goodwill and Licenses Impairment Assessment section of Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements for information on goodwill and licenses impairment testing policies and methods.

See Note 8—Licenses and Goodwill in the Notes to Consolidated Financial Statements for additional information related to goodwill and licenses activity in 2010 and 2009.

The following discussion compares the impairment test as of November 1, 2010 to that as of November 1, 2009.

Goodwill

U.S. Cellular tests goodwill for impairment at the level of reporting referred to as a "reporting unit." For purposes of impairment testing of goodwill in 2010, U.S. Cellular identified five reporting units based on geographic service areas. There were no changes to U.S. Cellular's reporting units, the allocation of goodwill to those reporting units, or to U.S. Cellular's overall goodwill impairment testing methodology between its two most recent impairment testing dates, November 1, 2010 and November 1, 2009.

A discounted cash flow approach was used to value each reporting unit, using value drivers and risks specific to the current industry and economic markets. The cash flow estimates incorporated assumptions that market participants would use in their estimates of fair value and may not be indicative of U.S. Cellular specific assumptions. Key assumptions made in this process were the revenue growth rate, discount rate, and projected capital expenditures. These assumptions were as follows as of the two most recent impairment testing dates:

The decrease in the discount rate between November 1, 2009 and 2010 was a result of the decrease in several of the market-participant inputs used to calculate the weighted average cost of capital ("WACC") due to improved market conditions, primarily the risk-free rate and levered beta, partially offset by a higher company-specific risk premium.

20

Table of Contents

The carrying value of each U.S. Cellular reporting unit as of November 1, 2010 was as follows:

As of November 1, 2010, the fair values of the reporting units exceeded their respective carrying values by amounts ranging from 46% to 121% of the respective carrying values. Therefore, no impairment of goodwill existed. Given that the fair values of the respective reporting units exceed their respective carrying values, provided all other assumptions remained the same, the discount rate would have to increase to a range of 14.4% to 19.8% to yield estimated fair values of reporting units that equal their respective carrying values at November 1, 2010. Further, assuming all other assumptions remained the same, the terminal growth rate assumptions would need to decrease to negative amounts, ranging from negative 73.4% to negative 12.5%, to yield estimates of fair value equal to the carrying values of the respective reporting units at November 1, 2010.

Licenses

U.S. Cellular tests licenses for impairment at the level of reporting referred to as a "unit of accounting." For purposes of its impairment testing of licenses as of November 1, 2010 and 2009, U.S. Cellular separated its FCC licenses into eighteen units of accounting based on geographic service areas. Thirteen of these eighteen units of accounting represented geographic groupings of licenses which, because they were not being utilized and, therefore, were not expected to generate cash flows from operating activities in the foreseeable future, were considered separate units of accounting for purposes of impairment testing.

Developed operating market licenses ("built licenses")

As indicated in Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements—Goodwill and Licenses Impairment Assessment, U.S. Cellular applies the build-out method to estimate the fair values of built licenses. Significant assumptions within the build-out method include the hypothetical build-out period, discount rate, long-term EBITDA margin, penetration rate, revenue growth rate, and capital expenditure requirements. The penetration rate and capital expenditure requirements varied among the different units of accounting and between years within the forecast periods. The following key assumptions were applied consistently across all units of accounting for purposes of the November 1, 2010 and 2009 licenses impairment assessment:

The discount rate used in the license valuation is less than the discount rate used in the valuation of reporting units for purposes of goodwill impairment testing. That is because the discount rate used for licenses does not include a company-specific risk premium as a wireless license would not be subject to such risk.

The discount rate is the most significant assumption used in the build-out method. The discount rate is estimated based on the overall risk-free interest rate adjusted for industry participant information, such as a typical capital structure (i.e., debt-equity ratio), the after-tax cost of debt and the cost of equity. The cost of equity takes into consideration the average risk specific to individual market participants. The decrease in the discount rate between November 1, 2009 and November 1, 2010 was a result of the

21

---

Table of Contents

decrease in several of the market-participant inputs used to calculate the weighted average cost of capital ("WACC") due to market conditions, primarily the risk free-rate and levered beta.

The results of the licenses impairment test at November 1, 2010 did not result in the recognition of a loss on impairment. Given that the fair values of the licenses exceed their respective carrying values, the discount rate would have to increase to a range of 9.9% to 11.1% in order to yield estimated fair values of licenses in the respective units of accounting that equal their respective carrying values at November 1, 2010.

Non-operating market licenses ("unbuilt licenses")

For purposes of performing impairment testing of unbuilt licenses, U.S. Cellular prepares estimates of fair value by reference to prices paid in recent auctions and market transactions where available. If such information is not available, the fair value of the unbuilt licenses is assumed to have changed by the same percentage, and in the same direction, that the fair value of built licenses measured using the build-out method changed during the period. There was no impairment loss recognized related to unbuilt licenses as a result of the November 1, 2010 licenses impairment test.

Carrying Value of Licenses

The carrying value of licenses at November 1, 2010 was as follows:

22

---

Table of Contents

All eighteen units of accounting had a fair value that exceeded the carrying value by at least 10% of the carrying value. However, any declines in the fair value of such licenses in future periods could result in the recognition of impairment losses on such licenses and any such impairment losses would have a negative impact on future results of operations. The impairment losses on licenses are not expected to have a future impact on liquidity. U.S. Cellular is unable to predict the amount, if any, of future impairment losses attributable to licenses. Further, historical operating results, particularly amounts related to impairment losses, are not indicative of future operating results.

Property, Plant and Equipment—Depreciation

U.S. Cellular provides for depreciation using the straight-line method over the estimated useful lives of the assets. U.S. Cellular depreciates its leasehold improvement assets associated with leased properties over periods ranging from one to thirty years, which approximates the shorter of the assets' economic lives or the specific lease terms.

Annually, U.S. Cellular reviews its property, plant and equipment lives to ensure that the estimated useful lives are appropriate. The estimated useful lives of property, plant and equipment are a critical accounting estimate because changing the lives of assets can result in larger or smaller charges for depreciation expense. Factors used in determining useful lives include technology changes, regulatory requirements, obsolescence and type of use. U.S. Cellular did not materially change the useful lives of its property, plant and equipment in 2010, 2009 or 2008.

Income Taxes

U.S. Cellular is included in a consolidated federal income tax return with other members of the TDS consolidated group. TDS and U.S. Cellular are parties to a Tax Allocation Agreement which provides that U.S. Cellular and its subsidiaries be included with the TDS affiliated group in a consolidated federal income tax return and in state income or franchise tax returns in certain situations. For financial statement purposes, U.S. Cellular and its subsidiaries calculate their income, income tax and credits as if they comprised a separate affiliated group. Under the Tax Allocation Agreement, U.S. Cellular remits its applicable income tax payments to TDS.

The amounts of income tax assets and liabilities, the related income tax provision and the amount of unrecognized tax benefits are critical accounting estimates because such amounts are significant to U.S. Cellular's financial condition and results of operations.

The preparation of the consolidated financial statements requires U.S. Cellular to calculate its provision for income taxes. This process involves estimating the actual current income tax liability together with assessing temporary differences resulting from the different treatment of items for tax purposes. These temporary differences result in deferred income tax assets and liabilities, which are included in U.S. Cellular's Consolidated Balance Sheet. U.S. Cellular must then assess the likelihood that deferred income tax assets will be realized based on future taxable income and, to the extent management believes that realization is not likely, establish a valuation allowance. Management's judgment is required in determining the provision for income taxes, deferred income tax assets and liabilities and any valuation allowance that is established for deferred income tax assets.

U.S. Cellular recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate resolution.

See Note 4—Income Taxes in the Notes to Consolidated Financial Statements for details regarding U.S. Cellular's income tax provision, deferred income taxes and liabilities, valuation allowances and unrecognized tax benefits, including information regarding estimates that impact income taxes.

Allowance for Doubtful Accounts

U.S. Cellular's accounts receivable primarily consist of amounts owed by customers pursuant to service contracts and for equipment sales, by agents for sales of equipment to them and by other wireless carriers whose customers have used U.S. Cellular's wireless systems.

The allowance for doubtful accounts is the best estimate of the amount of probable credit losses related to existing accounts receivable. The allowance is estimated based on historical experience and other factors that could affect collectability. Accounts receivable balances are reviewed on either an aggregate or individual basis for collectability depending on the type of receivable. When it is probable that an account balance will not be collected, the account balance is charged against the allowance for doubtful accounts. U.S. Cellular does not have any off-balance sheet credit exposure related to its customers. U.S. Cellular will continue to monitor its accounts receivable balances and related allowance for doubtful accounts on an ongoing basis to assess whether it has adequately provided for potentially uncollectible amounts.

See Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements in the Notes to Consolidated Financial Statements for additional information regarding U.S. Cellular's allowance for doubtful accounts.

Loyalty Reward Program

See the Revenue Recognition section of Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements to the Notes to Consolidated Financial Statements for a description of this program and the related accounting.

U.S. Cellular follows the deferred revenue method of accounting for its loyalty reward program. Under this method, revenue allocated to loyalty reward points is deferred and recognized at the time the customer redeems loyalty reward points. U.S. Cellular does not have sufficient historical data in which to estimate any portion of loyalty reward points that will not be redeemed. As such, 100% of the value of the loyalty reward points is deferred until redeemed. U.S. Cellular will periodically review and revise the redemption rate as appropriate based on history and related future expectations.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

U.S. Cellular is billed for all services it receives from TDS pursuant to the terms of various agreements between U.S. Cellular and TDS. These billings are included in U.S. Cellular's Selling, general and administrative expenses. Some of these agreements were established prior to U.S. Cellular's initial public offering, when TDS owned more than 90% of U.S. Cellular's outstanding capital stock, and may not reflect terms that would be obtainable from an unrelated third party through arms-length negotiations. Billings from TDS to U.S. Cellular are based on expenses specifically identified to U.S. Cellular and on allocations of common expenses. Such allocations are based on the relationship of U.S. Cellular's assets, employees, investment in property, plant and equipment and expenses to the total assets, employees, investment in property, plant and equipment and expenses of TDS. Management believes that the method TDS uses to allocate common expenses is reasonable and that all expenses and costs applicable to U.S. Cellular are reflected in U.S. Cellular's consolidated financial statements. Billings from TDS to U.S. Cellular totaled $107.5 million, $114.8 million and $113.3 million for 2010, 2009 and 2008, respectively.

The following persons are partners of Sidley Austin LLP, the principal law firm of U.S. Cellular and its subsidiaries: Walter C.D. Carlson, a director of U.S. Cellular, a director and non-executive Chairman of the Board of Directors of TDS and a trustee and beneficiary of a voting trust that controls TDS; William S. DeCarlo, the General Counsel of TDS and an Assistant Secretary of TDS and certain subsidiaries of TDS; and Stephen P. Fitzell, the General Counsel of U.S. Cellular and TDS Telecommunications Corporation and an Assistant Secretary of U.S. Cellular and certain other subsidiaries of TDS. Walter C.D. Carlson does not provide legal services to TDS, U.S. Cellular or their subsidiaries. U.S. Cellular and its subsidiaries incurred legal costs from Sidley Austin LLP of $9.8 million in 2010, $8.6 million in 2009 and $6.9 million in 2008.

The Audit Committee of the Board of Directors is responsible for the review and evaluation of all related party transactions, as such term is defined by the rules of the New York Stock Exchange.

PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
SAFE HARBOR CAUTIONARY STATEMENT

This Management's Discussion and Analysis of Financial Condition and Results of Operations and other sections of this Annual Report contain statements that are not based on historical facts, including the words "believes," "anticipates," "intends," "expects" and similar words. These statements constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause actual results, events or developments to be significantly different from any future results, events or developments expressed or implied by such forward-looking statements. Such factors include, but are not limited to, the following risks:

•

Intense competition in the markets in which U.S. Cellular operates could adversely affect U.S. Cellular's revenues or increase its costs to compete.

•

A failure by U.S. Cellular to successfully execute its business strategy or allocate resources or capital could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

•

A failure by U.S. Cellular's service offerings to meet customer expectations could limit U.S. Cellular's ability to attract and retain customers and could have an adverse effect on U.S. Cellular's operations.

•

U.S. Cellular's system infrastructure may not be capable of supporting changes in technologies and services expected by customers, which could result in lost customers and revenues.

•

An inability to obtain or maintain roaming arrangements with other carriers on terms that are acceptable to U.S. Cellular could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

•

U.S. Cellular currently receives a significant amount of roaming revenues. As a result of acquisitions by other companies in the wireless industry, U.S. Cellular roaming revenues have declined significantly from amounts earned in certain prior years. Further industry consolidation and continued build outs by other wireless carriers could cause roaming revenues to decline even more, which would have an adverse effect on U.S. Cellular's business, financial condition and results of operations.

•

A failure by U.S. Cellular to obtain access to adequate radio spectrum to meet current or anticipated future needs and/or to accurately predict future needs for radio spectrum could have an adverse effect on U.S. Cellular's business and operations.

•

To the extent conducted by the FCC, U.S. Cellular is likely to participate in FCC auctions of additional spectrum in the future as an applicant or as a non-controlling partner in another auction applicant and, during certain periods, will be subject to the FCC's anti-collusion rules, which could have an adverse effect on U.S. Cellular.

•

Changes in the regulatory environment or a failure by U.S. Cellular to timely or fully comply with any applicable regulatory requirements could adversely affect U.S. Cellular's financial condition, results of operations or ability to do business.

•

Changes in USF funding and/or intercarrier compensation could have a material adverse impact on U.S. Cellular's financial position or results of operations.

•

An inability to attract and/or retain highly competent management, technical, sales and other personnel could have an adverse effect on U.S. Cellular's business, financial condition or results of operations.

•

U.S. Cellular's assets are concentrated in the U.S. wireless telecommunications industry. As a result, its results of operations may fluctuate based on factors related entirely to conditions in this industry.

•

The completion of acquisitions by other companies has led to increased consolidation in the wireless telecommunications industry. U.S. Cellular's lower scale relative to larger wireless carriers has in the past and could in the future prevent or delay its access to new products including wireless devices, new technology and/or new content and applications which could adversely affect U.S. Cellular's ability to attract and retain customers and, as a result, could adversely affect its business, financial condition or results of operations.

MARKET RISK

Long-Term Debt

As of December 31, 2010, the majority of U.S. Cellular's debt was in the form of fixed-rate notes with original maturities ranging up to 30 years. Fluctuations in market interest rates can lead to significant fluctuations in the fair value of these fixed-rate notes.

The following table presents the scheduled principal payments on long-term debt and capital lease obligations, and the related weighted average interest rates by maturity dates at December 31, 2010:

Fair Value of Long-Term Debt

At December 31, 2010 and 2009, the estimated fair value of long-term debt obligations, excluding capital lease obligations and the current portion of such long-term debt, was $850.4 million and $853.9 million, respectively. The fair value of long-term debt, excluding capital lease obligations and the current portion of such long-term debt, was estimated using market prices for the 7.5% senior notes and discounted cash flow analysis for the 6.7% senior notes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS

United States Cellular Corporation ("U.S. Cellular"), a Delaware Corporation, is an 83%-owned subsidiary of Telephone and Data Systems, Inc. ("TDS").

Nature of Operations

U.S. Cellular owns, operates and invests in wireless systems throughout the United States. As of December 31, 2010, U.S. Cellular served 6.1 million customers in 26 states. U.S. Cellular operates as one reportable segment.

Principles of Consolidation

The accounting policies of U.S. Cellular conform to accounting principles generally accepted in the United States of America ("GAAP") as set forth in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC"). Unless otherwise specified, references to accounting provisions and GAAP in these notes refer to the requirements of the FASB ASC. The consolidated financial statements include the accounts of U.S. Cellular, its majority-owned subsidiaries, general partnerships in which U.S. Cellular has a majority partnership interest and variable interest entities ("VIEs") in which U.S. Cellular is the primary beneficiary. Both VIE and primary beneficiary represent terms defined by GAAP. Prior to January 1, 2010, the primary beneficiary of a VIE was the entity that recognized a majority of a VIE's expected gains or losses, as determined based on a quantitative model. Effective January 1, 2010, new provisions under GAAP related to accounting for VIEs provide for a more qualitative assessment in determining the primary beneficiary of a VIE. The revised consolidation guidance related to VIEs effective January 1, 2010 did not change U.S. Cellular's consolidated reporting entities.

Effective January 1, 2009, U.S. Cellular adopted new required provisions under GAAP related to the accounting and reporting for noncontrolling interests.

Pursuant to this adoption, the following provisions were applied prospectively effective January 1, 2009:

•

All earnings and losses of a subsidiary are attributed to the parent and the noncontrolling interest, even if the losses attributable to the noncontrolling interest result in a deficit noncontrolling interest balance. Previously, any losses exceeding the noncontrolling interest's investment in the subsidiary were attributed to the parent. This change did not have a significant impact on U.S. Cellular's financial statements in 2010 or 2009.

•

Once control of a subsidiary is obtained, changes in ownership interests in that subsidiary that do not result in a loss of control are accounted for as equity transactions. Previously, decreases in ownership interest in a subsidiary were accounted for as equity transactions, while increases in ownership interests of a subsidiary were accounted for as step acquisitions. This change did not have a significant impact on U.S. Cellular's financial statements in 2010 or 2009.

All material intercompany accounts and transactions have been eliminated.

Reclassifications

Certain prior year amounts have been reclassified to conform to the 2010 financial statement presentation. These reclassifications did not affect consolidated net income attributable to U.S. Cellular shareholders, cash flows, assets, liabilities or equity for the years presented.

Business Combinations

Effective January 1, 2009, U.S. Cellular adopted new required provisions under GAAP related to accounting for business combinations. Although the revised provisions still require that all business

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

combinations are to be accounted for at fair value in accordance with the acquisition method, they require U.S. Cellular to revise its application of the acquisition method in a number of significant aspects. Specifically, the new provisions require that transaction costs are to be expensed and that the acquirer must recognize 100% of the acquiree's assets and liabilities rather than a proportional share, for acquisitions of less than 100% of a business. In addition, the revised provisions eliminate the step acquisition model and provide that all business combinations, whether full, partial or step acquisitions, will result in all assets and liabilities of an acquired business being recorded at their fair values at the acquisition date.

During 2008, U.S. Cellular applied the provisions of GAAP related to business combinations in effect during that period. Similar to the revised provisions, the previous provisions required the application of the acquisition method whereby business combinations were to be accounted for at fair value. However, the previous provisions were different in a number of respects, including (but not limited to) the requirement that all direct and incremental costs relating to an acquisition be included in the acquisition costs, and the requirement that the acquirer only recognize its proportional share of the fair value of assets and liabilities acquired in a partial business acquisition.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (a) the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and (b) the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Significant estimates are involved in accounting for goodwill and indefinite-lived intangible assets, depreciation, amortization and accretion, allowance for doubtful accounts, loyalty reward points, and income taxes.

Cash and Cash Equivalents

Cash and cash equivalents include cash and short-term, highly liquid investments with original maturities of three months or less.

Outstanding checks totaled $17.5 million and $21.0 million at December 31, 2010 and 2009, respectively, and are classified as Accounts payable-Trade in the Consolidated Balance Sheet.

Short-Term and Long-Term Investments

As of December 31, 2010 and 2009, U.S. Cellular had $146.6 million and $0.3 million in Short-term investments and $46.0 million and $0 in Long-term investments, respectively. Short-term and Long-term investments consist of certificates of deposit (short-term only), U.S. treasuries and corporate notes, all of which are designated as held-to-maturity investments, and are recorded at amortized cost in the Consolidated Balance Sheet. The corporate notes are guaranteed by the Federal Deposit Insurance Corporation. For these investments, U.S. Cellular's objective is to earn a higher rate of return on funds that are not anticipated to be required to meet liquidity needs in the near term, while maintaining a low level of investment risk. See Note 3—Fair Value Measurements in the Notes to Consolidated Financial Statements for additional details on Short-term and Long-term investments.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable primarily consist of amounts owed by customers pursuant to service contracts and for equipment sales, by agents for sales of equipment to them and by other wireless carriers whose customers have used U.S. Cellular's wireless systems.

UNITED STATES CELLULAR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

The allowance for doubtful accounts is the best estimate of the amount of probable credit losses related to existing accounts receivable. The allowance is estimated based on historical experience and other factors that could affect collectability. Accounts receivable balances are reviewed on either an aggregate or individual basis for collectability depending on the type of receivable. When it is probable that an account balance will not be collected, the account balance is charged against the allowance for doubtful accounts. U.S. Cellular does not have any off-balance sheet credit exposure related to its customers.

The changes in the allowance for doubtful accounts during the years ended December 31, 2010, 2009 and 2008 were as follows:

Inventory

Inventory primarily consists of wireless devices stated at the lower of cost or market, with cost determined using the first-in, first-out method and market determined by replacement costs or estimated net realizable value.

Fair Value Measurements

Under the provisions of GAAP, fair value is a market-based measurement and not an entity-specific measurement, based on an exchange transaction in which the entity sells an asset or transfers a liability (exit price). The provisions also establish a fair value hierarchy that contains three levels for inputs used in fair value measurements. Level 1 inputs include quoted market prices for identical assets or liabilities in active markets. Level 2 inputs include quoted market prices for similar assets and liabilities in active markets or quoted market prices for identical assets and liabilities in inactive markets. Level 3 inputs are unobservable.

Licenses

Licenses consist of costs incurred in acquiring Federal Communications Commission ("FCC") licenses to provide wireless service. These costs include amounts paid to license applicants and owners of interests in entities awarded licenses and all direct and incremental costs related to acquiring the licenses.

U.S. Cellular has determined that wireless licenses are indefinite-lived intangible assets and, therefore, not subject to amortization based on the following factors:

•

Radio spectrum is not a depleting asset.

•

The ability to use radio spectrum is not limited to any one technology.

•

U.S. Cellular and its consolidated subsidiaries are licensed to use radio spectrum through the FCC licensing process, which enables licensees to utilize specified portions of the spectrum for the provision of wireless service.

•

U.S. Cellular and its consolidated subsidiaries are required to renew their FCC licenses every ten years or, in some cases, every fifteen years. To date, all of U.S. Cellular's license renewal applications have been granted by the FCC. Generally, license renewal applications filed by licensees otherwise in compliance with FCC regulations are routinely granted. If, however, a license renewal application is

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

challenged either by a competing applicant for the license or by a petition to deny the renewal application, the license will be renewed if the licensee can demonstrate its entitlement to a "renewal expectancy." Licensees are entitled to such an expectancy if they can demonstrate to the FCC that they have provided "substantial service" during their license term and have "substantially complied" with FCC rules and policies. U.S. Cellular believes that it is probable that its future license renewal applications will be granted.

Goodwill

U.S. Cellular has goodwill as a result of its acquisitions of wireless markets. Such goodwill represents the excess of the total purchase price over the fair value of net assets acquired in these transactions.

Goodwill and Licenses Impairment Assessment

Goodwill and licenses must be assessed for impairment annually or more frequently if events or changes in circumstances indicate that such assets might be impaired.

The impairment test for goodwill is a two-step process. The first step compares the fair value of the reporting unit to its carrying value. If the carrying amount exceeds the fair value, the second step of the test is performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. To calculate the implied fair value of goodwill in this second step, an enterprise allocates the fair value of the reporting unit to all of the assets and liabilities of that reporting unit (including any unrecognized intangible assets) as if the reporting unit had been acquired in a business combination and the fair value was the price paid to acquire the reporting unit. The excess of the fair value of the reporting unit over the amount assigned to the assets and liabilities of the reporting unit is the implied fair value of goodwill. If the carrying amount of goodwill exceeds the implied fair value of goodwill, an impairment loss is recognized for that difference.

The impairment test for an indefinite-lived intangible asset other than goodwill consists of comparing the fair value of the intangible asset to its carrying amount. If the carrying amount exceeds the fair value, an impairment loss is recognized for the difference.

Quoted market prices in active markets are the best evidence of fair value of an intangible asset or reporting unit and are used when available. If quoted market prices are not available, the estimate of fair value is based on the best information available, including prices for similar assets and the use of other valuation techniques. Other valuation techniques include present value analysis, multiples of earnings or revenues, or similar performance measures. The use of these techniques involve assumptions by management about factors that are uncertain including future cash flows, the appropriate discount rate, and other inputs. Different assumptions for these inputs could create materially different results.

Prior to 2009, U.S. Cellular completed the required annual impairment assessment of its licenses and goodwill as of April 1 of each year. As a result of the deterioration in the credit and financial markets and the decline of the overall economy in the fourth quarter of 2008, U.S. Cellular performed an interim impairment assessment of licenses and goodwill as of December 31, 2008. Effective April 1, 2009, U.S. Cellular adopted a new accounting policy whereby its annual impairment review of goodwill and indefinite-lived intangible assets will be performed as of November 1 instead of the second quarter of each year. The change in the annual goodwill and indefinite-lived intangible asset impairment testing date was made to better align the annual impairment test with the timing of U.S. Cellular's annual strategic planning process, which allows for a better estimate of the future cash flows used in discounted cash flow models to test for impairment. This change in accounting policy did not delay, accelerate or avoid an impairment charge.

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

U.S. Cellular tests goodwill for impairment at the level of reporting referred to as a reporting unit. For purposes of impairment testing of goodwill in 2010 and 2009, U.S. Cellular identified five reporting units. The five reporting units represent five geographic groupings of FCC licenses, representing five geographic service areas. U.S. Cellular tests licenses for impairment at the level of reporting referred to as a unit of accounting. For purposes of its annual impairment testing of licenses as of November 1, 2010 and 2009, U.S. Cellular combined its FCC licenses into eighteen units of accounting. Of these, thirteen of such eighteen units of accounting represented geographic groupings of licenses which, because they were not being utilized and, therefore, were not expected to generate cash flows from operating activities in the foreseeable future, were considered separate units of accounting for purposes of impairment testing. The five units of accounting for which licenses are being utilized are referred to as "built licenses" and the thirteen units of accounting for which licenses are not being utilized are referred to as "unbuilt licenses."

For purposes of impairment testing of goodwill, U.S. Cellular prepares valuations of each of the five reporting units. A discounted cash flow approach was used to value each reporting unit, using value drivers and risks specific to the current industry and economic markets. The cash flow estimates incorporated assumptions that market participants would use in their estimates of fair value. Key assumptions made in this process were the discount rate, estimated future cash flows, projected capital expenditures and the terminal growth rate.

In 2009, U.S. Cellular changed its method of estimating the fair value of built licenses for purposes of impairment testing from the multiple period excess cash flow method ("MPECF method") to the build-out method. U.S. Cellular elected to make this change as the build-out method is a more widely used and accepted valuation method in estimating the fair value of licenses for purposes of impairment testing in the wireless industry. U.S. Cellular does not believe the build-out method yields a significantly different estimate of the fair value of licenses than the MPECF method.

The MPECF method estimated the fair value of the units of accounting by measuring the future cash flows of the license groups, reduced by charges for contributory assets such as working capital, trademarks, existing subscribers, fixed assets and assembled workforce to arrive at the economic margin. A contributory asset charge for goodwill was subtracted from the economic margin to arrive at the after-tax excess cash flows applicable to the licenses.

The build-out method estimates the value of licenses by calculating future cash flows from a hypothetical start-up wireless company and assumes that the only assets available upon formation are the underlying licenses. To apply this method, a hypothetical build-out of the company's wireless network, infrastructure, workforce and related costs are projected based on market participant information. Calculated cash flows, along with a terminal value, are discounted to the present and summed to determine the estimated fair value.

For units of accounting which consist of unbuilt licenses, U.S. Cellular prepares estimates of fair value by reference to prices paid in recent auctions and market transactions where available. If such information is not available, the fair value of the unbuilt licenses is assumed to change by the same percentage, and in the same direction, that the fair value of built licenses measured using the build-out method changed during the period.

Investments in Unconsolidated Entities

Investments in unconsolidated entities consist of amounts invested in wireless entities in which U.S. Cellular holds a noncontrolling interest. U.S. Cellular follows the equity method of accounting for such investments in which its ownership interest equals or exceeds 20% for corporations and equals or exceeds 3% for partnerships and limited liability companies. The cost method of accounting is followed

for such investments in which U.S. Cellular's ownership interest is less than 20% for corporations and is less than 3% for partnerships and limited liability companies and for investments for which U.S. Cellular does not have the ability to exercise significant influence.

For its equity method investments for which financial information is readily available, U.S. Cellular records its equity in the earnings of the entity in the current period. For its equity method investments for which financial information is not readily available, U.S. Cellular records its equity in the earnings of the entity on a one quarter lag basis.

Property, Plant and Equipment

U.S. Cellular's Property, plant and equipment is stated at the original cost of construction or purchase including capitalized costs of certain taxes, payroll-related expenses, interest and estimated costs to remove the assets.

Expenditures that enhance the productive capacity of assets in service or extend their useful lives are capitalized and depreciated. Expenditures for maintenance and repairs of assets in service are charged to System operations expense or Selling, general and administrative expense, as applicable. Retirements and disposals of assets are recorded by removing the original cost of the asset (along with the related accumulated depreciation) from plant in service and charging it, together with removal cost less any salvage realized, to Loss on asset disposals, net.

Costs of developing new information systems are capitalized and amortized over their expected economic useful lives.

Depreciation

Depreciation is provided using the straight-line method over the estimated useful life of the assets.

U.S. Cellular depreciates leasehold improvement assets associated with leased properties over periods ranging from one to thirty years; such periods approximate the shorter of the assets' economic lives or the specific lease terms.

Useful lives of specific assets are reviewed throughout the year to determine if changes in technology or other business changes would warrant accelerating the depreciation of those specific assets. U.S. Cellular did not materially change the useful lives of its property, plant and equipment in 2010, 2009 or 2008.

Impairment of Long-lived Assets

U.S. Cellular reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the assets might be impaired. The impairment test for tangible long-lived assets is a two-step process. The first step compares the carrying value of the asset (or asset group) with the estimated undiscounted cash flows over the remaining asset (or asset group) life. If the carrying value of the asset (or asset group) is greater than the undiscounted cash flows, the second step of the test is performed to measure the amount of impairment loss. The second step compares the carrying value of the asset to its estimated fair value. If the carrying value exceeds the estimated fair value (less cost to sell), an impairment loss is recognized for the difference.

Quoted market prices in active markets are the best evidence of fair value of a tangible long-lived asset and are used when available. If quoted market prices are not available, the estimate of fair value is based on the best information available, including prices for similar assets and the use of other valuation techniques. A present value analysis of cash flow scenarios is often the best available valuation technique. The use of this technique involves assumptions by management about factors that are

uncertain including future cash flows, the appropriate discount rate, and other inputs. Different assumptions for these inputs could create materially different results.

Agent Liabilities

U.S. Cellular has relationships with agents, which are independent businesses that obtain customers for U.S. Cellular. At December 31, 2010 and 2009, U.S. Cellular had accrued $71.3 million and $55.2 million, respectively, for amounts due to agents. This amount is included in Other current liabilities in the Consolidated Balance Sheet.

Other Assets and Deferred Charges

Other assets and deferred charges primarily represent legal and other charges related to U.S. Cellular's various borrowing instruments, and are amortized over the respective term of each instrument. The amounts for deferred charges included in the Consolidated Balance Sheet at December 31, 2010 and 2009, are shown net of accumulated amortization of $11.9 million and $11.8 million, respectively.

Asset Retirement Obligations

U.S. Cellular accounts for asset retirement obligations in accordance with GAAP, which requires entities to record the fair value of a liability for legal obligations associated with an asset retirement in the period in which the obligations are incurred. At the time the liability is incurred, U.S. Cellular records a liability equal to the net present value of the estimated cost of the asset retirement obligation and increases the carrying amount of the related long-lived asset by an equal amount. The liability is accreted to its present value over a period ending with the estimated settlement date of the respective asset retirement obligation. Upon settlement of the obligation, any difference between the cost to retire the asset and the recorded liability (including accretion of discount) is recognized in the Consolidated Statement of Operations.

Treasury Shares

Common Shares repurchased by U.S. Cellular are recorded at cost as treasury shares and result in a reduction of equity. Treasury shares are reissued as part of U.S. Cellular's stock-based compensation programs. When treasury shares are reissued, U.S. Cellular determines the cost using the first-in, first-out cost method. The difference between the cost of the treasury shares and reissuance price is included in Additional paid-in capital or Retained earnings.

Revenue Recognition

Revenues from wireless operations consist primarily of:

•

Charges for access, airtime, roaming, long distance, data and other value added services provided to U.S. Cellular's retail customers and to end users through third-party resellers;

•

Charges to carriers whose customers use U.S. Cellular's systems when roaming;

•

Sales of equipment and accessories;

•

Amounts received from the Universal Service Fund ("USF") in states where U.S. Cellular has been designated an Eligible Telecommunications Carrier ("ETC"); and

•

Redemptions of loyalty reward points for products or services.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

Revenues related to wireless services and other value added services are recognized as services are rendered. Revenues billed in advance or in arrears of the services being provided are estimated and deferred or accrued, as appropriate.

Revenues from sales of equipment and accessories are recognized when title and risk of loss passes to the agent or end-user customer.

In October 2009, the FASB issued Accounting Standards Update No. 2009-13, Multiple Deliverable Revenue Arrangements—a consensus of FASB Emerging Issues Task Force ("ASU 2009-13"). ASU 2009-13 provides for less restrictive separation criteria that must be met for a deliverable to be considered a separate unit of accounting. Additionally, under this Standard, there is a hierarchy for determining the selling price of a unit of accounting and consideration must be allocated using a relative-selling price method. U.S. Cellular is required to adopt the provisions of ASU 2009-13 on January 1, 2011, however elected to adopt the provisions as of October 1, 2010 on a retroactive basis to January 1, 2010. U.S. Cellular made this election due to certain new service offerings (Belief Plans) with multiple elements that were introduced by U.S. Cellular in the fourth quarter of 2010. These new service offerings may include a combination of the following elements which are considered separate units of accounting under ASU 2009-13: wireless service (voice, messaging and data), wireless devices, phone replacement of such wireless handsets, and loyalty reward points that may be redeemed by customers for wireless products and services in future periods. The adoption of ASU 2009-13 on October 1, 2010 had no impact on any previously reported financial statement amounts for 2010 interim periods.

U.S. Cellular allocates revenue to each element of these service offerings accounted for under ASU 2009-13 using the relative selling price method. Under this method, arrangement consideration, which consists of the amounts billed to the customer net of any cash-based discounts, are allocated to each element on the basis of their relative selling price, on a stand-alone basis. Such stand-alone selling price is determined in accordance with the following hierarchy:

•

U.S. Cellular-specific objective evidence of stand-alone selling price, if available; otherwise

•

Third-party evidence of selling price, if it is determinable; otherwise

•

A best estimate of stand-alone selling price.

U.S. Cellular estimates stand-alone selling prices of the elements of its new service offerings as follows:

•

Wireless services—Based on the actual selling price U.S. Cellular offers when such plan is sold on a stand-alone basis, or if the plan is not sold on a stand-alone basis, U.S. Cellular's estimate of the price of such plan based on similar plans that are sold on a stand-alone basis.

•

Wireless devices—Based on the selling price of the respective wireless device when it is sold on a stand-alone basis.

•

Phone Replacement—Based on U.S. Cellular's estimate of the price of this service if it were sold on a stand-alone basis, which was calculated by estimating the cost of this program plus a reasonable margin.

•

Loyalty reward points—By estimating the retail price of the products and services for which points may be redeemed and dividing such amount by the number of loyalty points required to receive such products and services. This is calculated on a weighted average basis and requires U.S. Cellular to estimate the percentage of loyalty points that will be redeemed for each product or service.

U.S. Cellular follows the deferred revenue method of accounting for its loyalty reward program. Under this method, revenue allocated to loyalty reward points is deferred and recognized at the time the customer redeems loyalty reward points. U.S. Cellular does not have sufficient historical data in which to

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND RECENT ACCOUNTING PRONOUNCEMENTS (Continued)

estimate any portion of loyalty reward points that will not be redeemed. As such, 100% of the value of the loyalty reward points is deferred until redeemed.

The introduction of these new service offerings in conjunction with the adoption of ASU 2009-13 required U.S. Cellular to defer the recognition of revenue related to amounts billed to customers that are attributed to loyalty reward points, and therefore impacted the timing of revenue recognition related to such service offerings. As of December 31, 2010, $7.1 million of revenue was deferred related to loyalty reward points outstanding as of this date. This amount was recorded in Customer deposits and deferred revenues (a current liability account) in the Consolidated Balance Sheet, as customers may redeem their reward points within the current period.

Cash-based discounts and incentives, including discounts to customers who pay their bills through the use of on-line bill payment methods, are recognized as a reduction of Operating revenues concurrently with the associated revenue, and are allocated to the various products and services in the bundled offering based on their respective relative selling price.

In order to provide better control over wireless device quality, U.S. Cellular sells wireless devices to agents. U.S. Cellular pays rebates to agents at the time an agent activates a new customer or retains an existing customer in a transaction involving a wireless device. U.S. Cellular accounts for these rebates by reducing revenues at the time of the wireless device sale to the agent rather than at the time the agent activates a new customer or retains a current customer. Similarly, U.S. Cellular offers certain wireless device sales rebates and incentives to its retail customers and records the revenue net of the corresponding rebate or incentive. The total potential rebates and incentives are reduced by U.S. Cellular's estimate of rebates that will not be redeemed by customers based on historical experience of such redemptions.

Activation fees charged with the sale of service only, where U.S. Cellular does not also sell a wireless device to the customer, are deferred and recognized over the average customer life. U.S. Cellular defers recognition of a portion of commission expenses related to these activations in the amount of deferred activation fee revenues. This method of accounting provides for matching of revenues and direct incremental costs associated with such activations within each reporting period. GAAP requires that activation fees charged with the sale of equipment and service to be allocated to the equipment and service based upon the relative selling prices of each item. This generally results in the recognition of the activation fee as additional wireless device revenue at the time of sale.

ETC revenues recognized in the reporting period represent the amounts which U.S. Cellular is entitled to receive for such period, as determined and approved in connection with U.S. Cellular's designation as an ETC in various states.

Amounts Collected from Customers and Remitted to Governmental Authorities

U.S. Cellular records amounts collected from customers and remitted to governmental authorities net within a tax liability account if the tax is assessed upon the customer and U.S. Cellular merely acts as an agent in collecting the tax on behalf of the imposing governmental authority. If the tax is assessed upon U.S. Cellular, then amounts collected from customers as recovery of the tax are recorded in Service revenues and amounts remitted to governmental authorities are recorded in Selling, general and administrative expenses in the Consolidated Statement of Operations. The amounts recorded gross in revenues that are billed to customers and remitted to governmental authorities totaled $137.6 million, $109.1 million and $140.7 million for 2010, 2009 and 2008, respectively.

Advertising Costs

U.S. Cellular expenses advertising costs as incurred. Advertising costs totaled $265.2 million, $256.9 million and $277.8 million for 2010, 2009 and 2008, respectively.

Income Taxes

U.S. Cellular is included in a consolidated federal income tax return with other members of the TDS consolidated group. TDS and U.S. Cellular are parties to a Tax Allocation Agreement which provides that U.S. Cellular and its subsidiaries be included with the TDS affiliated group in a consolidated federal income tax return and in state income or franchise tax returns in certain situations. For financial statement purposes, U.S. Cellular and its subsidiaries calculate their income, income taxes and credits as if they comprised a separate affiliated group. Under the Tax Allocation Agreement, U.S. Cellular remits its applicable income tax payments to TDS. U.S. Cellular had a tax receivable balance with TDS of $40.8 million and a tax payable balance of $1.7 million as of December 31, 2010 and 2009, respectively.

Deferred taxes are computed using the liability method, whereby deferred tax assets are recognized for future deductible temporary differences and operating loss carryforwards, and deferred tax liabilities are recognized for future taxable temporary differences. Both deferred tax assets and liabilities are measured using the tax rates anticipated to be in effect when the temporary differences reverse. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. U.S. Cellular evaluates income tax uncertainties, assesses the probability of the ultimate settlement with the applicable taxing authority and records an amount based on that assessment.

Stock-Based Compensation

U.S. Cellular has established a long-term incentive plan, an employee stock purchase plan, and a non-employee director compensation plan. Also, U.S. Cellular employees are eligible to participate in the TDS employee stock purchase plan. These plans are described more fully in Note 15—Stock-based Compensation. These plans are considered compensatory plans; therefore, recognition of compensation cost for grants made under these plans is required.

U.S. Cellular values its share-based payment transactions using a Black-Scholes valuation model. Stock-based compensation cost recognized during the period is based on the portion of the share-based payment awards that is ultimately expected to vest. Accordingly, stock-based compensation cost recognized has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures and expected life are estimated based on historical experience related to similar awards, giving consideration to the contractual terms of the stock-based awards, vesting schedules and expectations of future employee behavior. U.S. Cellular believes that its historical experience provides the best estimates of future pre-vesting forfeitures and future expected life. The expected volatility assumption is based on the historical volatility of U.S. Cellular's common stock over a period commensurate with the expected life. The dividend yield assumption is zero because U.S. Cellular has never paid a dividend and has expressed its intention to retain all future earnings in the business. The risk-free interest rate assumption is determined using the implied yield for zero-coupon U.S. government issues with a remaining term that approximates the expected life of the stock options.

Compensation cost for stock option awards is recognized over the respective requisite service period of the awards, which is generally the vesting period, on a straight-line basis for each separate vesting

portion of the awards as if the awards were, in-substance, multiple awards (graded vesting attribution method).

Defined Contribution Plans

U.S. Cellular participates in a qualified noncontributory defined contribution pension plan sponsored by TDS; such plan provides pension benefits for the employees of U.S. Cellular and its subsidiaries. Under this plan, pension benefits and costs are calculated separately for each participant and are funded currently. Pension costs were $11.6 million, $12.8 million and $10.3 million in 2010, 2009 and 2008, respectively.

U.S. Cellular also participates in a defined contribution retirement savings plan ("401(k) plan"), sponsored by TDS. Total costs incurred from U.S. Cellular's contributions to the 401(k) plan were $15.3 million, $14.3 million and $13.9 million in 2010, 2009 and 2008, respectively.

Operating Leases

U.S. Cellular is a party to various lease agreements for office space, retail sites, cell sites and equipment that are accounted for as operating leases. Certain leases have renewal options and/or fixed rental increases. Renewal options that are reasonably assured of exercise are included in determining the lease term. U.S. Cellular accounts for certain operating leases that contain rent abatements, lease incentives and/or fixed rental increases by recognizing lease revenue and expense on a straight-line basis over the lease term.

Recent Accounting Pronouncements

In October 2009, the FASB issued Accounting Standards Update No. 2009-14, Certain Revenue Arrangements that include Software Elements ("ASU 2009-14"). ASU 2009-14 amends accounting and reporting guidance for revenue arrangements involving both tangible products and software that is "more than incidental to the tangible product as a whole." ASU 2009-14 is effective for U.S. Cellular on January 1, 2011. U.S. Cellular does not anticipate that this pronouncement will have a significant impact on its financial position or results of operations.

NOTE 2 NONCONTROLLING INTERESTS

Under GAAP, certain noncontrolling interests in consolidated entities with finite lives may meet the definition of mandatorily redeemable financial instruments. U.S. Cellular's consolidated financial statements include certain noncontrolling interests that meet this definition of mandatorily redeemable financial instruments. These mandatorily redeemable noncontrolling interests represent interests held by third parties in consolidated partnerships and limited liability companies ("LLCs"), where the terms of the underlying partnership or LLC agreement provide for a defined termination date at which time the assets of the subsidiary are to be sold, the liabilities are to be extinguished and the remaining net proceeds are to be distributed to the noncontrolling interest holders and U.S. Cellular in accordance with the respective partnership and LLC agreements. The termination dates of these mandatorily redeemable noncontrolling interests range from 2085 to 2107.

UNITED STATES CELLULAR CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 2 NONCONTROLLING INTERESTS (Continued)

The settlement value of U.S. Cellular's mandatorily redeemable noncontrolling interests in finite-lived subsidiaries is estimated to be $184.9 million at December 31, 2010. This amount represents the estimate of cash that would be due and payable to settle these noncontrolling interests assuming an orderly liquidation of the finite-lived consolidated partnerships and LLCs on December 31, 2010, net of estimated liquidation costs. This amount excludes redemption amounts recorded in Noncontrolling interests with redemption features in the Consolidated Balance Sheet. U.S. Cellular currently has no plans or intentions relating to the liquidation of any of the related partnerships or LLCs prior to their scheduled termination dates. The corresponding carrying value of the mandatorily redeemable noncontrolling interests in finite-lived consolidated partnerships and LLCs at December 31, 2010 was $60.9 million, and is included in Noncontrolling interests in the Consolidated Balance Sheet. The excess of the aggregate settlement value over the aggregate carrying value of these mandatorily redeemable noncontrolling interests is primarily due to the unrecognized appreciation of the noncontrolling interest holders' share of the underlying net assets in the consolidated partnerships and LLCs. Neither the noncontrolling interest holders' share, nor U.S. Cellular's share, of the appreciation of the underlying net assets of these subsidiaries is reflected in the consolidated financial statements. The estimate of settlement value was based on certain factors and assumptions which are subjective in nature. Changes in those factors and assumptions could result in a materially larger or smaller settlement amount.

NOTE 3 FAIR VALUE MEASUREMENTS

As of December 31, 2010 and 2009, U.S. Cellular did not have any financial assets or liabilities that were required to be recorded at fair value in its Consolidated Balance Sheet in accordance with GAAP. However, U.S. Cellular has applied the provisions of fair value accounting for purposes of computing the fair value of financial instruments for disclosure purposes as displayed below.

The fair values of Cash and cash equivalents and Short-term investments approximate their book values due to the short-term nature of these financial instruments. The fair values of Long-term investments were estimated using quoted market prices for the individual issuances. The fair value of long-term debt,

NOTE 3 FAIR VALUE MEASUREMENTS (Continued)

excluding capital lease obligations and the current portion of such long-term debt, was estimated using market prices for the 7.5% senior notes and discounted cash flow analysis for the 6.7% senior notes.

As of December 31, 2009, U.S. Cellular had certain Licenses recorded at fair value in its Consolidated Balance Sheet as a result of impairment losses recognized at or proximate to December 31, 2009. For Licenses recorded at fair value, the following table provides information regarding their classification in the fair value hierarchy:

See Note 1—Summary of Significant Accounting Policies and Recent Accounting Pronouncements for information regarding the methods and assumptions used to estimate the fair values for Licenses and a description of the levels in the fair value hierarchy.

NOTE 4 INCOME TAXES

U.S. Cellular's Prepaid income taxes were $41.4 million and $0.7 million at December 31, 2010 and 2009, respectively. At December 31, 2010, Prepaid income taxes included prepaid federal income taxes of $39.7 million and prepaid state income taxes of $1.7 million. At December 31, 2009, Prepaid income taxes included prepaid state income taxes of $0.7 million, and Accrued taxes included $2.0 million of accrued federal income taxes. The timing of the enactment of federal bonus depreciation provisions in 2010 caused a significant increase in prepaid federal income taxes at December 31, 2010.

Income tax expense is summarized as follows:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

NOTE 4 INCOME TAXES (Continued)

A reconciliation of U.S. Cellular's income tax expense computed at the statutory rate to the reported income tax expense, and the statutory federal income tax expense rate to U.S. Cellular's effective income tax expense rate is as follows:

U.S. Cellular's current net deferred tax asset totaled $26.8 million and $21.6 million at December 31, 2010 and 2009, respectively. The 2010 and 2009 current net deferred tax asset primarily represents the deferred tax effects of accrued liabilities and the allowance for doubtful accounts on customer receivables.

U.S. Cellular's noncurrent deferred income tax assets and liabilities at December 31, 2010 and 2009 and the temporary differences that gave rise to them were as follows:

At December 31, 2010, U.S. Cellular and certain subsidiaries had $617.9 million of state NOL carryforwards (generating a $27.8 million deferred tax asset) available to offset future taxable income primarily of the individual subsidiaries which generated the losses. The state NOL carryforwards expire between 2011 and 2030. Certain subsidiaries had federal NOL carryforwards (generating a $5.9 million deferred tax asset) available to offset future taxable income. The federal NOL carryforwards expire between 2011 and 2030. A valuation allowance was established for certain state NOL carryforwards and federal NOL carryforwards since it is more likely than not that a portion of such carryforwards will expire before they can be utilized.

NOTE 4 INCOME TAXES (Continued)

At December 31, 2010 and 2009, U.S. Cellular had $32.5 million and $34.4 million, respectively, in unrecognized tax benefits. If these benefits were recognized, they would have reduced income tax expense in 2010 and 2009 by $21.1 million and $18.9 million, respectively, net of the federal benefit from state income taxes.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

Unrecognized tax benefits are included in Accrued taxes and Other deferred liabilities and credits in the Consolidated Balance Sheet.

As of December 31, 2010, U.S. Cellular believes it is reasonably possible that unrecognized tax benefits could decrease by approximately $7.0 million in the next twelve months. The nature of the uncertainty primarily relates to state income tax positions and the expiration of statutes of limitation.

U.S. Cellular recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The amounts charged to income tax expense related to interest and penalties totaled $3.0 million, $2.1 million and $4.4 million in 2010, 2009 and 2008, respectively. Accrued interest and penalties were $19.3 million and $15.7 million at December 31, 2010 and 2009, respectively.

U.S. Cellular is included in TDS' consolidated federal income tax return. U.S. Cellular also files various state and local income tax returns. The TDS consolidated group remains subject to federal income tax audits for the tax years after 2007.

In conjunction with an Internal Revenue Service ("IRS") audit of the TDS consolidated group's federal income tax returns for the tax years 2002 through 2005, TDS made a $38 million deposit with the IRS in 2009 related to an initial proposed assessment made by the IRS related to a specific tax position. U.S. Cellular then paid TDS a $34 million deposit in 2009, which represented U.S. Cellular's proportionate share of the TDS deposit. The purpose of the deposit was to eliminate any potential interest expense subsequent to the deposit. The IRS subsequently conceded the specific tax position, and after closure of the IRS audit for the tax years 2002 through 2005, the IRS returned this $38 million deposit to TDS in 2010, and TDS also returned U.S. Cellular's $34 million deposit in 2010.

NOTE 5 VARIABLE INTEREST ENTITIES (VIEs)

From time to time, the FCC conducts auctions through which additional spectrum is made available for the provision of wireless services. U.S. Cellular participated in spectrum auctions indirectly through its interests in Aquinas Wireless L.P. ("Aquinas Wireless"), King Street Wireless L.P. ("King Street Wireless"), Barat Wireless L.P. ("Barat Wireless") and Carroll Wireless L.P. ("Carroll Wireless"), collectively, the "limited partnerships." Each limited partnership participated in and was awarded spectrum licenses in one of four separate spectrum auctions (FCC Auctions 78, 73, 66 and 58). Each limited partnership qualified as a "designated entity" and thereby was eligible for bidding credits with respect to licenses purchased in accordance with the rules defined by the FCC for each auction. In most cases, the bidding credits resulted in a 25% discount from the gross winning bid.

Consolidated VIEs

As of December 31, 2010, U.S. Cellular consolidates the following VIEs under GAAP:

•

Aquinas Wireless;

•

King Street Wireless and King Street Wireless, Inc., the general partner of King Street Wireless;

•

Barat Wireless and Barat Wireless, Inc., the general partner of Barat Wireless; and

•

Carroll Wireless and Carroll PCS, Inc., the general partner of Carroll Wireless.

U.S. Cellular holds a variable interest in the entities listed above. It has made capital contributions and/or advances to these entities. The power to direct the activities of the VIEs that most significantly impact their economic performance is shared. Specifically, the general partner of each of these VIEs has the exclusive right to manage, operate and control the limited partnerships and make all decisions to carry on the business of the partnerships; however, the general partner of each partnership needs consent of the limited partner, a U.S. Cellular subsidiary, to sell or lease certain licenses, to make certain large expenditures, admit other partners or liquidate the limited partnerships. Although the power to direct the activities of the VIEs is shared, U.S. Cellular has a disproportionate level of exposure to the variability associated with the economic performance of the VIEs, indicating that U.S. Cellular is the primary beneficiary of the VIEs in accordance with GAAP. Accordingly, these VIEs are consolidated.

Following is a summary of the capital contributions and advances made to each entity by U.S. Cellular as of December 31, 2010. The amounts shown in the table below exclude funds provided to these entities solely from the shareholder of the general partner.

The following table presents the classification of the consolidated VIEs' assets and liabilities in U.S. Cellular's Consolidated Balance Sheet.
