Notes to Consolidated Financial Statements

Note 1 Basis of Presentation

United States Cellular Corporation (“U.S. Cellular”), a Delaware corporation, is an 84%-owned subsidiary of Telephone and Data Systems, Inc. (“TDS”).

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”). The consolidated financial statements include the accounts of U.S. Cellular, subsidiaries in which it has a controlling financial interest, general partnerships in which U.S. Cellular has a majority partnership interest and certain entities in which U.S. Cellular has a variable interest that require consolidation under GAAP. All material intercompany accounts and transactions have been eliminated.

The unaudited consolidated financial statements included herein have been prepared by U.S. Cellular pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, U.S. Cellular believes that the disclosures included herein are adequate to make the information presented not misleading. Calculated amounts and percentages are based on the underlying actual numbers rather than the numbers rounded to millions as presented. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in U.S. Cellular’s Annual Report on Form 10-K (“Form 10-K”) for the year ended December 31, 2015.

The accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring items, unless otherwise disclosed) necessary for the fair statement of U.S. Cellular’s financial position as of March 31, 2016 and December 31, 2015, and its results of operations, cash flows and changes in equity for the three months ended March 31, 2016 and 2015. The Consolidated Statement of Comprehensive Income was not included because comprehensive income for the three months ended March 31, 2016 and 2015 equaled net income. These results are not necessarily indicative of the results to be expected for the full year.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers. In August 2015, the FASB issued Accounting Standards Update 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, requiring the adoption of ASU 2014-09 on January 1, 2018 for U.S. Cellular. Early adoption as of January 1, 2017 is permitted; however, U.S. Cellular does not intend to adopt early. U.S. Cellular is evaluating the effects that adoption of ASU 2014-09 will have on its financial position and results of operations.

In August 2014, the FASB issued Accounting Standards Update 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 requires U.S. Cellular to assess its ability to continue as a going concern each interim and annual reporting period and provide certain disclosures if there is substantial doubt about the entity’s ability to continue as a going concern, including management’s plan to alleviate the substantial doubt. U.S. Cellular is required to adopt the provisions of ASU 2014-15 for the annual period ending December 31, 2016, but early adoption is permitted. The adoption of ASU 2014-15 will not impact U.S. Cellular’s financial position or results of operations but may impact future disclosures.

In July 2015, the FASB issued Accounting Standards Update 2015-11, Inventory: Simplifying the Measurement of Inventory (“ASU 2015-11”), which requires inventory to be measured at the lower of cost or net realizable value. U.S. Cellular is required to adopt ASU 2015-11 on January 1, 2017. Early adoption is permitted. U.S. Cellular is evaluating the effects that adoption of ASU 2015-11 will have on its financial position and results of operations.

In January 2016, the FASB issued Accounting Standards Update 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). This ASU introduces changes to current accounting for equity investments and financial liabilities under the fair value option and the presentation and disclosure requirements for financial instruments. U.S. Cellular is required to adopt ASU 2016-01 on January 1, 2018. Certain provisions are eligible for early adoption. U.S. Cellular is evaluating the effects that adoption of ASU 2016-01 will have on its financial position and results of operations.

In February 2016, the FASB issued Accounting Standards Update 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 requires lessees to record a right-of-use asset and lease liability for almost all leases. This ASU does not substantially impact lessor accounting. U.S. Cellular is required to adopt ASU 2016-02 on January 1, 2019. Early adoption is permitted. Upon adoption of ASU 2016-02, U.S. Cellular expects a substantial increase to assets and liabilities on its balance sheet. U.S. Cellular is still evaluating the full effects that adoption of ASU 2016-02 will have on its financial position and results of operations.

Table of Contents

In March 2016, the FASB issued Accounting Standards Update 2016-04, Liabilities – Extinguishments of Liabilities: Recognition of Breakage from Certain Prepaid Stored-Value Products (“ASU 2016-04”). ASU 2016-04 requires companies that sell prepaid stored-value products redeemable for goods, services or cash at third-party merchants to recognize breakage (i.e. the value that is ultimately not redeemed by the consumer) in a way that is consistent with how it will be recognized under the new revenue recognition standard. U.S. Cellular is required to adopt ASU 2016-04 on January 1, 2018. Early adoption is permitted. U.S. Cellular is evaluating the effects that adoption of ASU 2016-04 will have on its financial position and results of operations.

In March 2016, the FASB issued Accounting Standards Update 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”). The amendments in ASU 2016-08 clarify the guidance on principal versus agent considerations as it relates to recognizing revenue. U.S. Cellular is required to adopt ASU 2016-08 on January 1, 2018 in conjunction with the effective date of ASU 2014-09. Early adoption as of January 1, 2017 is permitted; however, U.S. Cellular does not intend to adopt early. U.S. Cellular is evaluating the effects that adoption of ASU 2016-08 will have on its financial position and results of operations.

In March 2016, the FASB issued Accounting Standards Update 2016-09, Compensation – Stock Compensation: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 intends to simplify the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. U.S. Cellular is required to adopt ASU 2016-09 on January 1, 2017. Early adoption is permitted. U.S. Cellular is evaluating the effects that adoption of ASU 2016-09 will have on its financial position, results of operations and cash flows.

In April 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing (“ASU 2016-10”). ASU 2016-10 provides clarification around identifying performance obligations and accounting arrangements whereby a license is granted as it relates to ASC 606 – Revenue from Contracts with Customers. U.S. Cellular is required to adopt ASU 2016-10 on January 1, 2018 in conjunction with the effective date of ASU 2014-09. Early adoption as of January 1, 2017 is permitted; however, U.S. Cellular does not intend to adopt early. U.S. Cellular is evaluating the effects that adoption of ASU 2016-10 will have on its financial position and results of operations.

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 $17 million and $21 million for the three months ended March 31, 2016 and 2015, respectively.

Note 2 Fair Value Measurements

As of March 31, 2016 and December 31, 2015, U.S. Cellular did not have any financial or nonfinancial assets or liabilities that were required to be recorded at fair value in its Consolidated Balance Sheet in accordance with GAAP.

The provisions of GAAP 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. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. A financial instrument’s level within the fair value hierarchy is not representative of its expected performance or its overall risk profile and, therefore, Level 3 assets are not necessarily higher risk than Level 2 or Level 1 assets.

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.

|  |  | Level within the Fair Value Hierarchy |  | March 31, 2016 |  | December 31, 2015
|  |  |  | Book Value |  | Fair Value |  | Book Value |  | Fair Value

| Other | 2 |  |  | 211 |  |  | 211 |  |  | 214 |  |  | 214

Table of Contents

The fair value of Cash and cash equivalents approximates the book value due to the short-term nature of these financial instruments. Long-term debt excludes capital lease obligations and the current portion of Long-term debt. The fair value of “Retail” Long-term debt was estimated using market prices for the 6.95% Senior Notes, 7.25% Senior Notes due 2063 and 7.25% Senior Notes due 2064. U.S. Cellular’s “Institutional” debt consists of the 6.7% Senior Notes which are traded over the counter. U.S. Cellular’s “Other” debt consists of a senior term loan credit facility. U.S. Cellular estimated the fair value of its Institutional and Other debt through a discounted cash flow analysis using the interest rates or estimated yield to maturity for each borrowing, which ranged from 3.19% to 7.84% and 3.19% to 7.51% at March 31, 2016 and December 31, 2015, respectively.

Note 3 Equipment Installment Plans

U.S. Cellular offers customers, through its owned and agent distribution channels, the option to purchase certain devices under equipment installment contracts over a specified time period. For certain equipment installment plans (“EIP”), after a specified period of time or amount of payments, the customer may have the right to upgrade to a new device and have the remaining unpaid equipment installment contract balance waived, subject to certain conditions, including trading in the original device in good working condition and signing a new equipment installment contract. U.S. Cellular values this trade-in right as a guarantee liability. The guarantee liability is initially measured at fair value and is determined based on assumptions including the probability and timing of the customer upgrading to a new device and the fair value of the device being traded-in at the time of trade-in. As of March 31, 2016 and December 31, 2015, the guarantee liability related to these plans was $77 million and $93 million, respectively, and is reflected in Customer deposits and deferred revenues in the Consolidated Balance Sheet.

U.S. Cellular equipment installment plans do not provide for explicit interest charges. For equipment installment plans with a duration of greater than twelve months, U.S. Cellular imputes interest. Equipment installment plan receivables had a weighted average effective imputed interest rate of 9.9% and 9.7% as of March 31, 2016 and December 31, 2015, respectively.

The following table summarizes unbilled equipment installment plan receivables as of March 31, 2016 and December 31, 2015. Such amounts are included in the Consolidated Balance Sheet as Accounts receivable – customers and agents and Other assets and deferred charges, where applicable.

| March 31, 2016 |  | December 31, 2015
(Dollars in millions) |  |  |  |  |
Short-term portion of unbilled equipment installment plan receivables, gross | $ | 300 |  | $ | 279
Short-term portion of unbilled deferred interest |  | (23) |  |  | (21)
Short-term portion of unbilled allowance for credit losses |  | (16) |  |  | (14)
Short-term portion of unbilled equipment installment plan receivables, net | $ | 261 |  | $ | 244
Long-term portion of unbilled equipment installment plan receivables, gross | $ | 91 |  | $ | 76
Long-term portion of unbilled deferred interest |  | (3) |  |  | (2)
Long-term portion of unbilled allowance for credit losses |  | (7) |  |  | (6)
Long-term portion of unbilled equipment installment plan receivables, net | $ | 81 |  | $ | 68

U.S. Cellular assesses the collectability of the equipment installment plan receivables based on historical payment experience, account aging and other qualitative factors and provides an allowance for estimated losses. The credit profiles of U.S. Cellular’s customers on equipment installment plans are similar to those of U.S. Cellular customers with traditional subsidized plans. Customers with a higher risk credit profile are required to make a deposit for equipment purchased through an installment contract.

Note 4 Earnings Per Share

Basic earnings per share attributable to U.S. Cellular shareholders is computed by dividing Net income attributable to U.S. Cellular shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share attributable to U.S. Cellular shareholders is computed by dividing Net income attributable to U.S. Cellular shareholders by the weighted average number of common shares outstanding during the period adjusted to include the effects of potentially dilutive securities. Potentially dilutive securities primarily include incremental shares issuable upon exercise of outstanding stock options and the vesting of restricted stock units.

Table of Contents

The amounts used in computing earnings per common share and the effects of potentially dilutive securities on the weighted average number of common shares were as follows:

|  | Three Months Ended
|  | March 31,
|  | 2016 |  | 2015
(Dollars and shares in millions, except per share amounts) |  |  |  |  |

Diluted earnings per share attributable to U.S. Cellular shareholders | $ | 0.10 |  | $ | 1.89
1 | Includes effects of stock options and restricted stock units.

Certain Common Shares issuable upon the exercise of stock options or vesting of restricted stock units were not included in average diluted shares outstanding for the calculation of Diluted earnings per share attributable to U.S. Cellular shareholders because their effects were antidilutive. The number o f such Common Shares excluded was approximately 2 million shares for both the three months ended March 31, 2016 and 2015.

Note 5 Acquisitions, Divestitures and Exchanges

In the first quarter of 2016, U.S. Cellular entered into multiple agreements to transfer FCC licenses in non-operating markets and receive FCC licenses in operating markets. The agreements were with third parties and provide for the transfer of certain AWS and PCS spectrum licenses and approximately $29 million, net, in cash to U.S. Cellular, in exchange for U.S. Cellular transferring certain AWS, PCS and 700 MHz spectrum licenses to the third parties. The transactions are subject to regulatory approval and other customary closing conditions, and are expected to close in 2016. Upon closing of each transaction, U.S. Cellular expects to recognize a gain. As a result of these exchange agreements, licenses with a carrying value of $26 million have been classified as “Assets held for sale” in the Consolidated Balance Sheet as of March 31, 2016.

In 2015 and 2016, U.S. Cellular entered into multiple spectrum license purchase agreements that have not yet closed. The aggregate purchase price for these spectrum licenses is $54 million. These agreements are for spectrum licenses located in U.S. Cellular’s existing operating markets and are expected to close in 2016.

Note 7 Investments in Unconsolidated Entities

Investments in unconsolidated entities consist of amounts invested in wireless entities in which U.S. Cellular holds a noncontrolling interest. These investments are accounted for using either the equity or cost method.

The following table, which is based in part on information provided by third parties, summarizes the combined results of operations of U.S. Cellular’s equity method investments.

Note 8 Variable Interest Entities

In February 2015, the FASB issued Accounting Standards Update 2015-02, Consolidation: Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 changes consolidation accounting including revising certain criteria for identifying variable interest entities. U.S. Cellular adopted the provisions of this standard as of January 1, 2016. As a result, certain consolidated subsidiaries and unconsolidated entities that were not defined as variable interest entities under previous accounting guidance are defined as variable interest entities under the provisions of ASU 2015-02. U.S. Cellular’s modified retrospective adoption of ASU 2015-02 did not change the group of entities which U.S. Cellular is required to consolidate in its financial statements. Accordingly, the adoption of ASU 2015-02 did not impact its financial position or results of operations.

Consolidated VIEs

U.S. Cellular consolidates variable interest entities (“VIEs”) in which it has a controlling financial interest as defined by GAAP and is therefore deemed the primary beneficiary. A controlling financial interest will have both of the following characteristics: (a) the power to direct the VIE activities that most significantly impact economic performance and (b) the obligation to absorb the VIE losses and right to receive benefits that are significant to the VIE. U.S. Cellular reviews these criteria initially at the time it enters into agreements and subsequently when events warranting reconsideration occur. These VIEs have risks similar to those described in the “Risk Factors” in U.S. Cellular’s Form 10-K for the year ended December 31, 2015.

The following VIEs were formed to participate in FCC auctions of wireless spectrum and to fund, establish, and provide wireless service with respect to any FCC licenses won in the auctions:

- Advantage Spectrum L.P. (“Advantage Spectrum”) and Frequency Advantage L.P., the general partner of Advantage Spectrum;
- Aquinas Wireless L.P. (“Aquinas Wireless”); and
- King Street Wireless L.P. (“King Street Wireless”) and King Street Wireless, Inc., the general partner of King Street Wireless.

These particular VIEs are collectively referred to as designated entities. Historically and as of March 31, 2016, U.S. Cellular consolidate d these VIEs.

Table of Contents

The power to direct the activities that most significantly impact the economic performance of these VIEs is shared. Specifically, the general partner 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. The general partner of each partnership needs the consent of the limited partner, a n indirect 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 these VIEs is shared, U.S. Cellular has the most significant 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. Therefore, in accordance with GAAP, these VIEs are consolidated.

In March 2015, King Street Wireless made a $60 million distribution to its owners. Of this distribution, $6 million was provided to King Street Wireless, Inc. and $54 million was provided to U.S. Cellular.

FCC Auction 97 ended in January 2015. U.S. Cellular participated in Auction 97 indirectly through its interest in Advantage Spectrum. A n indirect subsidiary of U.S. Cellular is a limited partner in Advantage Spectrum. Advantage Spectrum applied as a designated entity, and expects to receive bid credits with respect to spectrum purchased in Auction 97. Advantage Spectrum was the winning bidder for 124 licenses for an aggregate bid of $338 million, after its expected designated entity discount of 25%. This amount is classified as Licenses in U.S. Cellular’s Consolidated Balance Sheet. Advantage Spectrum’s bid amount, less the initial deposit of $60 million paid in 2014, plus certain other charges totaling $2 million, was paid to the FCC in March 2015. As of March 31, 2016 and as of the filing date of this Form 10-Q, these licenses have not yet been granted by and are still pending before the FCC.

The remaining VIEs are comprised of limited partnerships that provide wireless service. ASU 2015-02 modified the manner in which limited partnerships and similar legal entities are evaluated under the variable interest model. A limited partnership is a variable interest entity unless the limited partners hold substantive participating rights or kick-out rights over the general partners. For certain limited partnerships, U.S. Cellular is the general partner and manages the operations. In these partnerships, the limited partners do not have substantive kick-out or participating rights and, further, such limited partners do not have the authority to remove the general partner. Therefore, beginning January 1, 2016, these limited partnerships are also recognized as VIEs and are consolidated under the variable interest model. Prior to the adoption of ASU 2015-02, these limited partnerships were consolidated under the voting interest model.

Unconsolidated VIEs

U.S. Cellular manages the operations of and holds a variable interest in certain other limited partnerships, but is not the primary beneficiary of these entities and, therefore, does not consolidate them under the variable interest model outlined in ASU 2015-02.

U.S. Cellular’s total investment in these unconsolidated entities was $5 million at March 31, 2016 and December 31, 2015, and is included in Investments in unconsolidated entities in U.S. Cellular’s Consolidated Balance Sheet. The maximum exposure from unconsolidated VIEs is limited to the investment held by U.S. Cellular in those entities.

Other Related Matters

U.S. Cellular made contributions, loans and/or advances to its VIEs totaling $13 million and $281 million during the three months ended March 31, 2016 and March 31, 2015, respectively. U.S. Cellular may agree to make additional capital contributions and/or advances to these or other VIEs and/or to their general partners to provide additional funding for operations or the development of licenses granted in various auctions. U.S. Cellular may finance such amounts with a combination of cash on hand, borrowings under its revolving credit agreement and/or other long-term debt. There is no assurance that U.S. Cellular will be able to obtain additional financing on commercially reasonable terms or at all to provide such financial support.

U.S. Cellular Mission and Strategy

U.S. Cellular’s mission is to provide exceptional wireless communication services which enhance consumers’ lives, increase the competitiveness of local businesses, and improve the efficiency of government operations in the mid-sized and rural markets served.

In 2016, U.S. Cellular will continue to execute on its strategies to grow revenues by increasing its customer base, driving smartphone adoption and ongoing data usage monetization. Strategic efforts include:

- U.S. Cellular deployed 4G LTE as a result of U.S. Cellular’s strategic initiative to enhance its network. 4G LTE now reaches 99% of postpaid customers and 98% of cell sites. The adoption of data-centric smartphones and connected devices is driving significant growth in data traffic. At the end of the first quarter, 74% of postpaid customers had 4G capable devices, with the LTE network handling 88% of data traffic. In 2015, U.S. Cellular began field trials related to VoLTE technology. VoLTE technology, when deployed commercially, will enable customers to utilize the LTE network for both voice and data services. These trials were completed in the first quarter of 2016. Efforts related to the deployment of VoLTE will continue throughout 2016.
- In the first quarter of 2016, U.S. Cellular continued to enhance its spectrum position and monetize non-strategic assets by entering into multiple agreements to transfer FCC licenses in non-operating markets and receive FCC licenses in operating markets. The agreements were with third parties for the purchase of certain spectrum licenses for cash and for the transfer of certain AWS and PCS spectrum licenses and approximately $29 million, net, in cash to U.S. Cellular, in exchange for U.S. Cellular transferring certain AWS, PCS and 700 MHz spectrum licenses to the third parties. The transactions are subject to regulatory approval and other customary closing conditions, and are expected to close in 2016. Upon closing of each transaction, U.S. Cellular expects to recognize a gain. See Note 5 — Acquisitions, Divestitures and Exchanges for additional information related to these transactions.
- U.S. Cellular is focused on expanding its solutions available to business and government customers, including a growing suite of machine-to-machine solutions across various categories. U.S. Cellular will continue to enhance its advanced wireless services and connected solutions for consumer, business and government customers.

| Retail customers – end of period | 4,667,000 | 4,853,000 |
Commentary U.S. Cellular believes the increase in n et additions in 2016 is a result of competitive services and products priced to offer the best value to customers and expanded equipment installment plan offerings. Postpaid churn continued to decline due to enhancements in the customer experience, targeted retention programs and improvement in the overall credit mix of gross additions.

| Commentary Smartphone penetration increased to 75% of the post paid handset customer base in the first quarter of 2016, up from 67% in the same period a year ago. Smartphones represented 92% and 86% of total handset sales during the first quarter of 2016 and 2015, respectively. This contributed to increased service revenues from data. Continued growth in revenues and costs related to data services and products may result in increased operating expenses and the need for additional investment in spectrum, network capacity and network enhancements.

Commentary

Postpaid ARPU and Postpaid ARPA decreased in 2016 driven by industry-wide price competition, together with discounts on shared data plans provided to customers on equipment installment plans and those providing their own device at the time of activation or renewal. Postpaid ARPU also decreased due to net additions of connected devices, which on a per unit basis contribute less revenue than handsets. These factors were partially offset by the impacts of continued adoption of smartphones and shared data plans.

Equipment installment plans increase equipment sales revenue as customers pay for their wireless devices in installments at a total device price that is generally higher than the device price offered to customers in conjunction with alternative plans that are subject to a service contract. Equipment installment plans also have the impact of reducing service revenues as many equipment installment plans provide for reduced monthly access charges. In order to show the trends in total service and equipment revenues received from customers, U.S. Cellular has presented Postpaid ABPU and Postpaid ABPA, which are calculated as Postpaid ARPU and Postpaid ARPA plus average monthly equipment installment plan billings per customer and account, respectively. Equipment installment plan billings increased in 2016 due to increased adoption of equipment installment plans by postpaid customers. Postpaid ABPU decreased in 2016 as the increase in equipment installment plan billings was more than offset by the Postpaid ARPU drivers discussed above. Postpaid ABPA, however, increased in 2016 due to the increase in equipment installment plan billings and an increase in device connections per account, partially offset by the Postpaid ARPU and Postpaid ARPA drivers discussed above.

Key components of changes in the statement of operations line items were as follows:

Commentary

Total operating revenues

Service revenues decreased as a result of (i) a decrease in retail service revenues driven by industry-wide price competition, including discounts on shared data plans provided to customers on equipment installment plans and those providing their own device at the time of activation or renewal; and (ii) reductions in inbound roaming revenue driven by lower roaming rates. Such reductions were partially offset by a n increase in the average customer base and continued adoption of shared data plans.

Federal USF revenue was $23 million in 2016, which remained flat year over year. Pursuant to the FCC's Reform Order (“Reform Order”), U.S. Cellular’s Federal USF support was to be phased down at the rate of 20% per year beginning July 1, 2012. The Phase II Mobility Fund was not operational as of July 2014 and, therefore, as provided by the Reform Order, the phase down was suspended at 60% of the baseline amount. U.S. Cellular will continue to receive USF support at the 60% level until the FCC takes further action. At this time, U.S. Cellular cannot predict what changes that the FCC might make to the USF high cost support program and, accordingly, cannot predict whether such changes will have a material adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Equipment sales revenues increased due primarily to an increase in average revenue per device sold from sales under equipment installment plans, an increase in the number of devices sold, an increase in accessory sales, and a mix shift to smartphones and connected devices. Equipment installment plan sales contributed $147 million and $68 million in 2016 and 2015, respectively.

System operations expenses

Maintenance, utility and cell site expenses increased 6% to $97 million reflecting higher support costs for the expanded 4G LTE network, increased cell site rent, the completion of certain tower maintenance and repair projects, and other maintenance activities.

Expenses incurred when U.S. Cellular’s customers used other carriers’ networks while roaming decreased 13% to $42 million driven primarily by lower rates for both voice and data traffic, partially offset by increased data roaming usage.

Customer usage expenses decreased 13% to $45 million driven by lower fees for platform and content providers, a decrease in long distance charges driven by rate reductions, and a decrease in circuit costs from the migration to LTE.

U.S. Cellular expects system operations expenses to increase in the 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 data usage. However, these increases are expected to be offset to some extent by cost savings generated by shifting data traffic to the 4G LTE network from the 3G network.

Cost of equipment sold

The increase in Cost of equipment sold is a result of a 9% increase in devices sold and a mix shift to higher cost devices. Cost of equipment sold in 2016 included $160 million related to equipment installment plan sales compared to $87 million in 2015. Loss on equipment, representing Equipment sales revenues less Cost of equipment sold, was $57 million and $101 million in 2016 and 2015, respectively.

Selling, general and administrative expenses

Selling expenses increased 6% to $177 million due primarily to higher retail and agent commissions expense driven by higher accessory sales and increased activations and renewals, higher retail bonus expense, and increased advertising spend.

General and administrative expenses decreased 8% to $185 million due primarily to lower bad debts expense driven by improved receivables collectability, low er consulting expenses related to the billing system, and reduced expense of customer service operations.

(Gain) loss on sale of business and other exit costs, net

The net gain in 2015 was due primarily to a $108 million gain recognized on the sale of towers and certain related contracts, assets and liabilities.

(Gain) loss on license sales and exchanges, net

The net gain in 2015 was due primarily to a $125 million gain recognized on the exchange s of certain of U.S. Cellular’s unbuilt PCS licenses for cert ain other PCS licenses and cash.

Commentary

Equity in earnings of unconsolidated entities

Equity in earnings of unconsolidated entities r epresents U.S. Cellular’s share of net income from entities in which it has a noncontrolling interest and that are accounted for by the equity method. U.S. Cellular’s investment in the Los Angeles SMSA Limited Partnership (“LA Partnership”) contributed $19 million and $20 million to Equity in earnings of unconsolidated entities in 2016 and 2015, respectively. See Note 7 — Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for additional information.

Interest and dividend income

Interest and dividend income increased due to imputed interest income recognized on equipment installment plans of $11 million and $7 million in 2016 and 2015, respectively. See Note 3 — Equipment Installment Plans in the Notes to Consolidated Financial Statements for additional information.

Interest expense

Interest expense increased due primarily to U.S. Cellular’s issuance of $300 million of 7.25% Senior Notes due 2064 in November 2015 and borrowing of $225 million on its senior term loan facility that was drawn in July 2015.

Income tax expense

U.S. Cellular’s effective tax rate on Income before income taxes in 2016 and 2015 was 53.1% and 39.5%, respectively. The higher rate in 2016 is due primarily to discrete tax adjustments that have a disproportionate impact on the tax rate because of the relatively low pretax income in the quarter. As discrete items are not annualized, this rate may not be indicative of the annual rate for 2016.

Net income attributable to noncontrolling interests, net of tax

The decrease is due to lower income from certain partnerships in 2016.

Liquidity and Capital Resources

Sources of Liquidity

U.S. Cellular believes that existing cash and investment balances, funds available under its revolving credit facility, and expected cash flows from operating and investing activities provide liquidity for U.S. Cellular to meet its normal day-to-day operating needs and debt service requirements for the coming year.

U.S. Cellular operates a capital-intensive business. Historically, U.S. Cellular has used internally-generated funds and also has obtained substantial funds from external sources for general corporate purposes. In the past, U.S. Cellular’s existing cash and investment balances, funds available under its revolving credit facility, funds from other financing sources, including a term loan and other long-term debt, and cash flows from operating, investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for U.S. Cellular to meet its normal day-to-day operating needs and debt service requirements, to finance the build-out and enhancement of markets and to fund acquisitions. There is no assurance that this will be the case in the future. It may be necessary from time to time to increase the size of the existing revolving credit facility, to put in place a new credit facility, or to obtain other forms of financing in order to fund potential expenditures. U.S. Cellular’s liquidity would be adversely affected if, among other things, U.S. Cellular is unable to obtain short or long-term financing on acceptable terms, U.S. Cellular makes significant spectrum license purchases in FCC auctions or from other parties, the LA Partnership does not resume or reduces distributions compared to historical levels, or Federal USF and/or other regulatory support payments continue to decline. In addition, although sales of assets or businesses by U.S. Cellular have been an important source of liquidity in recent periods, U.S. Cellular does not expect a similar level of such sales in the future, which will reduce a source of liquidity. In recent years, U.S. Cellular’s credit rating has declined to sub-investment grade.

Although U.S. Cellular currently has a significant cash balance, in certain recent periods, U.S. Cellular has incurred negative free cash flow (defined as Cash flows from operating activities less Cash paid for additions to property, plant and equipment) and this will continue in the future if operating results do not improve or capital expenditures are not reduced. U.S. Cellular currently expects to have negative free cash flow in 2016 due to anticipated growth in equipment installment plan receivables combined with significant capital expenditures. U.S. Cellular may require substantial additional capital for, among other uses, funding day-to-day operating needs, working capital, acquisitions of providers of wireless telecommunications services, spectrum license or system acquisitions, system development and network capacity expansion, debt service requirements, the repurchase of shares, the payment of dividends, or making additional investments. There can be no assurance that sufficient funds will continue to be available to U.S. Cellular or its subsidiaries on terms or at prices acceptable to U.S. Cellular. Insufficient cash flows from operating activities, changes in its credit ratings, defaults of the terms of debt or credit agreements, uncertainty of access to capital, deterioration in the capital markets, reduced regulatory capital at banks which in turn limits their ability to borrow and lend, other changes in the performance of U.S. Cellular or in market conditions or other factors could limit or restrict the availability of financing on terms and prices acceptable to U.S. Cellular, which could require U.S. Cellular to reduce its acquisition, capital expenditure and business development programs, reduce the acquisition of spectrum licenses, and/or reduce or cease share repurchases and/or the payment of dividends. U.S. Cellular cannot provide assurance that circumstances that could have a material adverse effect on its liquidity or capital resources will not occur. Any of the foregoing would have an adverse impact on U.S. Cellular’s businesses, financial condition or results of operations.

Cash and Cash Equivalents

Cash and cash equivalents include cash and money market investments. The primary objective of U.S. Cellular’s Cash and cash equivalents is for use in its operations and acquisition, capital expenditure and business development programs.

| A t March 31, 2016, U.S. Cellular’s cash and cash equivalents totaled $772 million compared to $715 million at December 31, 2015. T he majority of U.S. Cellular’s Cash and cash equivalents w as held in bank deposit accounts and in money market funds that invest exclusively in U.S. Treasury Notes 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.

Table of Contents

Financing

As of March 31, 2016, U.S. Cellular’s unused capacity under its revolving credit facility was $282 million. This credit facility matures in December 2017. U.S. Cellular believes it was in compliance with all of the financial covenants and requirements set forth in its revolving credit facility as of March 31, 2016.

U.S. Cellular has in place an effective shelf registration statement on Form S-3 to issue senior or subordinated debt securities.

The proceeds from any of the aforementioned financing facilities are available for general corporate purposes, including spectrum purchases and capital expenditures.

The long-term debt payments due for the remainder of 2016 and the next four years represent less than 4% of U.S. Cellular’s total long-term debt obligation measured as of March 31, 2016.

Capital Expenditures

Capital expenditures (i.e., additions to property, plant and equipment and system development expenditures), which in clude accruals and capitalized interest, in 2016 and 2015 were as follows:

| U.S. Cellular’s capital expenditures for 2016 are expected to be approximately $500 million. These expenditures are expected to be for the following general purposes: Expand and enhance network coverage, including construction of a new regional connectivity center and providing additional capacity to accommodate increased network usage, principally data usage, by current customers; Deploy VoLTE technology; Expand and enhance the retail store network; and Develop and enhance office systems.

U.S. Cellular plans to finance its capital expenditures program for 2016 using primarily Cash flows from operating activities and, as necessary, existing cash balances and borrowings under its revolving credit agreement and/or other long-term debt.

Acquisitions, Divestitures and Exchanges

U.S. Cellular may be engaged from time-to-time in negotiations relating to the acquisition, divestiture or exchange of companies, properties or wireless spectrum. In general, U.S. Cellular may not disclose such transactions until there is a definitive agreement. 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 capital. As part of this strategy, U.S. Cellular reviews attractive opportunities to acquire additional wireless operating markets and wireless spectrum, including pursuant to FCC auctions. U.S. Cellular also may seek to divest outright or include in exchanges for other wireless interests those interests that are not strategic to its long-term success.

On March 18, 2016, the FCC released a list of applicants that successfully completed applications for the forward auction of 600 MHz spectrum licenses, referred to as Auction 1000, including U.S. Cellular. Auction 1000 has commenced with the beginning of the reverse auction on March 29, 2016. Forward auction bidding is likely to begin a couple of months later, and could continue for three months or longer. See “Regulatory Matters — FCC Auction 1000.” Prior to becoming a qualified bidder, U.S. Cellular must make an upfront payment, the size of which establishes its initial bidding eligibility. If U.S. Cellular is a winning bidder in the auction, it may be required to make additional payments to the FCC that may be substantial. In such event, U.S. Cellular plans to finance such payments from its existing cash balances, borrowings under its revolving credit agreement and/or additional long-term debt.

In 2015 and in 2016, U.S. Cellular entered into multiple spectrum license purchase agreements that have not yet closed. The aggregate purchase price for these spectrum licenses is $54 million. In the first quarter of 2016, U.S. Cellular also entered into multiple agreements to transfer FCC licenses in non-operating markets and receive FCC licenses in operating markets. The agreements were with third parties and provide for the transfer of certain AWS and PCS spectrum licenses and approximately $29 million, net, in cash to U.S. Cellular, in exchange for U.S. Cellular transferring certain AWS, PCS and 700 MHz spectrum licenses to the third parties. These license purchase and exchange transactions are expected to close in 2016.

Variable Interest Entities

U.S. Cellular consolidates certain entities as “variable interest entities” under GAAP. See Note 8 — Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information related to these variable interest entities. U.S. Cellular may elect to make capital contributions and/or advances to variable interest entities 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 its repurchase program. For additional information related to the current repurchase authorization, see Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

Share repurchases made under this authorization in 2016 and 2015 were as follows:

Contractual and Other Obligations

There w ere no material change s outside the ordinary course of business between December 31, 2015 and March 31, 2016 to the Contractual and Other Obligations disclosed in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in U.S. Cellular’s Form 10-K for the year ended December 31, 2015.

Off-Balance Sheet Arrangements

U.S. Cellular had no transactions, agreements or other contractual arrangements with unconsolidated entities involving “off-balance sheet arrangements,” as defined by SEC 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.

Consolidated Cash Flows

U.S. Cellular operates a capital- and marketing-intensive business. U.S. Cellular makes substantial investments to acquire wireless licenses and properties and to construct and upgrade wireless telecommunications 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 to U.S. Cellular’s networks. U.S. Cellular utilizes cash on hand, cash from operating activities, cash proceeds from divestitures and dispositions of investments, short-term credit facilities and long-term debt financing to fund its acquisitions (including licenses), construction costs, operating expenses and share repurchases. Cash flows may fluctuate from quarter-to-quarter and year-to-year due to seasonality, the timing of acquisitions and divestitures, capital expenditures and other factors. The following discussion summarizes U.S. Cellular's cash flow activities for the three months ended March 31, 2016 and 2015.

2016 Commentary

U.S. Cellular’s Cash and cash equivalents increased $57 million in 2016. Net cash provided by operating activities was $163 million in 2016 due to net income of $9 million as adjusted for non-cash items of $151 million. Changes in working capital items resulted in a net use of cash of $11 million. U.S. Cellular received a federal tax refund of $28 million related to an overpayment of the 2015 expected tax liability. This was offset by a use of cash of $41 million due to an increase in equipment installment plan receivables, which are expected to continue to increase and further require the use of working capital in the near term. The net cash provided by operating activities was partially offset by Cash flows used for investing activities of $102 million. Cash paid in 2016 for additions to property, plant and equipment totaled $103 million and is reported in the Consolidated Statement of Cash Flows.

2015 Commentary

Cash flows from operating activities were $255 million in 2015, contributing to a net increase in Cash and cash equivalents of $125 million for the period. Changes in w orking capital items provided net cash of $185 million. As a result of increased focus by U.S. Cellular to sell through inventory of wireless devices on hand in 2015, inventory levels decreased. During 2015, U.S. Cellular received tax refunds of $66 million related to an overpayment of the 2014 expected tax liability and the carryback of its 2014 net operating loss to the 2012 and 2013 tax years. In addition, income taxes incurred on the sale of towers and on the license exchange in 2015 were not payable until periods after March 31, 2015, resulting in increased income tax payable amounts included in Accrued taxes.

Table of Contents

Cash flows used for investing activities were $120 million in 2015. Cash paid for additions to property, plant and equipment totaled $116 million in 2015, and is reported in the Consolidated Statement of Cash Flows. During 2015, a $278 million payment was made by Advantage Spectrum L.P. to the FCC for licenses for which it was the provisional winning bidder in Auction 97. Cash received from divestitures and exchanges in 2015 included $117 million related to licenses and $141 million related to the sale of 359 towers and certain related contracts, assets and liabilities.

Consolidated Balance Sheet Analysis

The following discussion addresses certain captions in the consolidated balance sheet and changes therein. This discussion is intended to highlight the significant changes and is not intended to fully reconcile the changes. Changes in financial condition during 2016 are as follows:

Cash and cash equivalents

Cash and cash equivalents increased $57 million. See the Consolidated Cash Flows discussion above for an analysis of cash and cash equivalents.

Other current assets

Other current assets decreased $32 million due primarily to the receipt of a federal income tax refund of $28 million in March 2016.

Assets held for sale

Assets held for sale increased $26 million due to reclassification of Licenses to this account as a result of exchange agreements with third parties. The license exchange agreements are expected to close in 2016. See Note 5 – Acquisitions, Divestitures and Exchanges for additional information.

Accrued compensation

Accrued compensation decreased $27 million due primarily to bonus payments in March 2016.

Application of Critical Accounting Policies a nd Estimates

U.S. Cellular prepares its consolidated financial statemen ts in accordance with 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 Consolidat ed Financial Statements and U.S. Cellular’s Application of Critical Accounting Policies and Estimates is discussed in detail in Management’s Discussion and Analysis of Financial Condition and Results of Operations, b oth of which are included in U.S. Cellular’s Form 10-K for the year ended December 31, 2015. There were no material changes to U.S. Cellular’s application of critical accounting policies and estimates during the three months ended March 31, 2016.

Recent Accounting Pronouncements

See Note 1 — Basis of Presentation in the Notes to Consolidated Financial Statements for information on recent accounting pronouncements.

Regulatory Matters

The discussion below includes updates related to recent regulatory developments. These updates should be read in conjunction with the disclosures previously provided under “Regulatory Matters” in U.S. Cellular’s Form 10-K for the year ended December 31, 2015.

FCC Auction 1000

On March 18, 2016, the FCC released a list of applicants that successfully completed applications for the forward auction of 600 MHz spectrum licenses, referred to as Auction 1000, which included U.S. Cellular. Auction 1000 has commenced with the beginning of the reverse auction on March 29, 2016. Forward auction bidding is likely to begin a couple of months later, and could continue for three months or longer. As a result of its participation, since February 10, 2016, U.S. Cellular has been subject to FCC anti-collusion rules that place certain restrictions on public disclosures and business communications with other companies relating to U.S. Cellular’s participation. These restrictions will continue until the down payment deadline for Auction 1000, which will be ten business days after release of the FCC’s Channel Reassignment Public Notice, following the end of the forward auction. These anti-collusion rules, which could last six months or more from February 10, 2016, may restrict the conduct of certain U.S. Cellular activities with other applicants in Auction 1000 as well as with nationwide providers of wireless services which are not applicants in Auction 1000. The restrictions could have an adverse effect on U.S. Cellular’s business, financial condition or results of operations.

Supplemental Information

U.S. Cellular sometimes uses information derived from consolidated financial information but not presented in its financial statements prepared in accordance with U.S. GAAP to evaluate the performance of its business. Certain of these measures are considered “non-GAAP financial measures” under U.S. Securities and Exchange Commission Rules. Specifically, U.S. Cellular has referred to the following measures in this Form 10-Q Report:

- Adjusted EBITDA
- Operating Cash Flow
- Free Cash Flow

- Adjusted Free Cash Flow

Below is a reconciliation of each of these measures.

Adjusted EBITDA and Operating Cash Flow

Adjusted EBITDA (earnings before interest, taxes, depreciation, amortization and accretion), is defined as net income adjusted for the items set forth in the reconciliation. Operating cash flow is defined as net income adjusted for the items set forth in the reconciliation. Adjusted EBITDA and Operating cash flow exclude these items in order to show operating results on a more comparable basis from period-to-period. From time-to-time, U.S. Cellular may exclude other items from Adjusted EBITDA and/or Operating cash flow if such items help reflect operating results on a more comparable basis. U.S. Cellular does not intend to imply that any such items that are excluded are non-recurring, infrequent or unusual; such items may occur in the future. Adjusted EBITDA and Operating cash flow are not measures of financial performance under GAAP and should not be considered as alternatives to net income as indicators of the company’s operating performance or as alternatives to cash flows from operating activities, determined in accordance with GAAP, as indicators of cash flows or as measures of liquidity. U.S. Cellular believes Adjusted EBITDA and Operating cash flow are useful measures of U.S. Cellular’s operating results before significant recurring non-cash charges, gains and losses, and other items as indicated below.

Free Cash Flow and Adjusted Free Cash Flow

The following table presents Free cash flow and Adjusted free cash flow. Free cash flow is defined as Cash flows from operating activities less Cash paid for additions to property, plant and equipment. Adjusted free cash flow is defined as Cash flows from operating activities (which includes cash outflows related to the Sprint decommissioning), as adjusted for cash proceeds from the Sprint Cost Reimbursement (which are included in Cash flows from investing activities in the Consolidated Statement of Cash Flows), less Cash paid for additions to property, plant and equipment. Free cash flow and Adjusted free cash flow are non-GAAP financial measures which U.S. Cellular believes may be useful to investors and other users of its financial information in evaluating the amount of cash generated by business operations (including cash proceeds from the Sprint Cost Reimbursement), after Cash paid for additions to property, plant and equipment.

The Purchase and Sale Agreement also contemplated certain other agreements. These agreements require Sprint to reimburse U.S. Cellular up to $200 million (the “Sprint Cost Reimbursement”) for certain network decommissioning costs, network site lease rent and termination costs, network access termination costs, and employee termination benefits for specified engineering employees.

U.S. Cellular maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed in its reports filed or submitted under the Exchange Act is processed, recorded, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to U.S. Cellular’s management, including its principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

As required by SEC Rule 13a-15(b), U.S. Cellular carried out an evaluation, under the supervision and with the participation of management, including its principal executive officer and principal financial officer, of the effectiveness of the design and operation of U.S. Cellular’s disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on this evaluation, U.S. Cellular’s principal executive officer and principal financial officer concluded that U.S. Cellular’s disclosure controls and procedures were effective as of March 31, 2016, at the reasonable assurance level.
