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

Executive Overview

The following discussion and analysis compares United States Cellular Corporation’s (UScellular) financial results for the three months ended March 31, 2021, to the three months ended March 31, 2020. It should be read in conjunction with UScellular’s interim consolidated financial statements and notes included herein, and with the description of UScellular’s business, its audited consolidated financial statements and Management's Discussion and Analysis of Financial Condition and Results of Operations (MD&A) included in UScellular’s Annual Report on Form 10-K (Form 10-K) for the year ended December 31, 2020. Certain numbers included herein are rounded to millions for ease of presentation; however, certain calculated amounts and percentages are determined using the unrounded numbers. 

This report contains statements that are not based on historical facts, including the words “believes,” “anticipates,” “estimates,” “expects,” “plans,” “intends,” “projects” and similar expressions. These statements constitute and represent “forward looking statements” as this term is defined in 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. See Private Securities Litigation Reform Act of 1995 Safe Harbor Cautionary Statement for additional information.

UScellular uses certain “non-GAAP financial measures” and each such measure is identified in the MD&A. A discussion of the reason UScellular determines these metrics to be useful and reconciliations of these measures to their most directly comparable measures determined in accordance with accounting principles generally accepted in the United States of America (GAAP) are included in the Supplemental Information Relating to Non-GAAP Financial Measures section within the MD&A of this Form 10-Q Report.

UScellular Mission and Strategy

UScellular’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 markets UScellular serves.

UScellular's strategy is to attract and retain customers through a value proposition comprising a high-quality network, outstanding customer service, and competitive devices, plans and pricing - all provided with a community focus. Strategic efforts include:

▪UScellular offers economical and competitively priced service plans and devices to its customers and is focused on increasing revenues from sales of related products such as accessories and device protection plans and from new services such as home internet. In addition, UScellular is focused on expanding its solutions available to business and government customers.

▪UScellular continues to devote efforts to enhance its network capabilities, including by deploying 5G technology. 5G technology helps address customers’ growing demand for data services and creates opportunities for new services requiring high speed and reliability as well as low latency. UScellular's 5G deployment is initially focused on mobility services using its low band spectrum. UScellular has acquired high-band spectrum and is in the process of acquiring mid-band spectrum, which it will deploy in the future to further enable the delivery of 5G services. UScellular has launched commercial 5G services in portions of substantially all of UScellular’s markets and will continue to launch in additional areas in the coming years. In addition to the deployment of 5G technology, UScellular is also modernizing its 4G LTE network to further enhance 4G LTE speeds.

▪UScellular 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, UScellular actively seeks attractive opportunities to acquire wireless spectrum, including pursuant to FCC auctions.

Total postpaid handset net losses decreased for the three months ended March 31, 2021, when compared to the same period last year due primarily to (i) higher gross additions as a result of improved promotional offering effectiveness and higher consumer switching activity and (ii) lower handset defections as a result of a reduction in non-pay defections.

Total postpaid connected device net losses decreased for the three months ended March 31, 2021, when compared to the same period last year due to a decrease in tablet defections, partially offset by a decrease in gross additions due to lower demand for internet related products as compared to the three months ended March 31, 2020.

Postpaid Revenue

Operating Revenues

(Dollars in millions)

Service revenues consist of:

▪Retail Service - Charges for voice, data and value-added services and recovery of regulatory costs

▪Inbound Roaming - Charges to other wireless carriers whose customers use UScellular’s wireless systems when roaming

▪Other Service - Amounts received from the Federal USF, tower rental revenues, and miscellaneous other service revenues

Equipment revenues consist of:

▪Sales of wireless devices and related accessories to new and existing customers, agents, and third-party distributors

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

Total operating revenues

Retail service revenues increased for the three months ended March 31, 2021, primarily as a result of an increase in Postpaid ARPU as previously discussed in the Operational Overview section as well as an increase in the average number of postpaid subscribers.

Inbound roaming revenues decreased for the three months ended March 31, 2021, primarily driven by lower data revenues resulting from lower usage. UScellular expects inbound roaming revenues to continue to decline during 2021 relative to prior year levels.

Other service revenues increased for the three months ended March 31, 2021, resulting from increases in tower rental revenues and miscellaneous other service revenues.

Equipment sales revenues increased for the three months ended March 31, 2021, due primarily to an increase in smartphone sales as well as an increase in the average revenue per device for smartphones due to an increase in sales of higher priced smartphones.

System operations expenses

System operations expenses increased for the three months ended March 31, 2021, due to higher circuit costs as well as an increase in roaming expense as a result of higher data roaming usage, partially offset by lower data rates.

Cost of equipment sold

Cost of equipment sold increased for the three months ended March 31, 2021, due primarily to an increase in smartphone sales as well as an increase in the average cost per device for smartphones due to an increase in sales of higher priced smartphones.

Selling, general and administrative expenses

Selling, general and administrative expenses decreased for the three months ended March 31, 2021, due primarily to decreases in (i) bad debts expense driven by fewer non-pay customers as a result of better credit mix and improved customer payment behavior, as well as a discrete charge that was recorded in March 2020 related to UScellular's participation in the FCC Keep Americans Connected Pledge and (ii) advertising expenses.

Depreciation, amortization and accretion

Depreciation, amortization, and accretion decreased for the three months ended March 31, 2021, due to certain billing system assets reaching their end of life in 2020, partially offset by an increase in depreciation expense due to increased capital expenditures throughout 2020.

N/M - Percentage change not meaningful

Equity in earnings of unconsolidated entities

Equity in earnings of unconsolidated entities represents UScellular’s share of net income from entities in which it has a noncontrolling interest and that are accounted for using the equity method. UScellular’s investment in the Los Angeles SMSA Limited Partnership (LA Partnership) contributed pretax income of $19 million and $22 million for the three months ended March 31, 2021 and 2020, respectively. See Note 8 — Investments in Unconsolidated Entities in the Notes to Consolidated Financial Statements for additional information.

Interest and dividend income

Interest and dividend income decreased for the three months ended March 31, 2021, driven primarily by lower interest rates.

Interest expense

Interest expense increased for the three months ended March 31, 2021, primarily as a result of the issuance of $500 million of 6.25% Senior Notes in August 2020 and $500 million of 5.50% Senior Notes in December 2020.

Income tax expense

The effective tax rate on Income before income taxes for the three months ended March 31, 2021 and 2020, was 30.4% and 5.0%, respectively. The higher effective tax rate in 2021 as compared to 2020 is due primarily to the income tax benefits of the CARES Act included in the 2020 tax rate, which do not recur as benefits in the 2021 tax rate.

The CARES Act provided retroactive eligibility of bonus depreciation on qualified improvement property put into service after December 31, 2017 and a 5-year carryback of net operating losses generated in years 2018-2020. As the statutory federal tax rate applicable to certain years within the carryback period is 35%, carryback to those years provided a tax benefit in excess of the current federal statutory rate of 21%, resulting in a reduction of income tax expense in 2020 and an expected cash refund of taxes paid in prior years.

8

Liquidity and Capital Resources

Sources of Liquidity

UScellular operates a capital-intensive business. In the past, UScellular’s existing cash and investment balances, funds available under its revolving credit and receivables securitization agreements, funds from other financing sources, including a term loan and other long-term debt, and cash flows from operating and certain investing and financing activities, including sales of assets or businesses, provided sufficient liquidity and financial flexibility for UScellular 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, primarily of wireless spectrum licenses. There is no assurance that this will be the case in the future. See Market Risk for additional information regarding maturities of long-term debt.

UScellular has incurred negative free cash flow at times in the past and this could occur in the future. However, UScellular believes that existing cash and investment balances, funds available under its revolving credit agreement, expected future tax refunds and expected cash flows from operating and investing activities will provide sufficient liquidity for UScellular to meet its normal day-to-day operating needs and debt service requirements for the coming years. UScellular will continue to monitor the rapidly changing business and market conditions and plans to take appropriate actions, as necessary, to meet its liquidity needs.

UScellular may require substantial additional capital for, among other uses, funding day-to-day operating needs including working capital, acquisitions of providers of wireless telecommunications services, wireless spectrum license acquisitions, capital expenditures, agreements to purchase goods or services, leases, debt service requirements, the repurchase of shares, or making additional investments. It may be necessary from time to time to increase the size of the existing revolving credit agreement, to put in place new credit agreements, or to obtain other forms of financing in order to fund potential expenditures.

Cash and Cash Equivalents

Cash and cash equivalents include cash and money market investments.

Cash and Cash Equivalents

(Dollars in millions)

The majority of UScellular’s Cash and cash equivalents are held in bank deposit accounts and in money market funds that purchase only debt issued by the U.S. Treasury or U.S. government agencies.

Financing

Revolving Credit Agreement

In March 2020, UScellular entered into a $300 million unsecured revolving credit agreement with certain lenders and other parties. Amounts under the revolving credit agreement may be borrowed, repaid and reborrowed from time to time until maturity in March 2025. As of March 31, 2021, there were no outstanding borrowings under the revolving credit agreement, except for letters of credit, and UScellular's unused borrowing capacity was $298 million.

Term Loan Agreement

In February 2021, UScellular borrowed $217 million under its senior term loan credit agreement. As of March 31, 2021, UScellular has borrowed the full amount available under the senior term loan credit agreement of $300 million. See Note 9 — Debt in the Notes to Consolidated Financial Statements for additional information related to the senior term loan agreement.

9

Receivables Securitization Agreement

UScellular, through its subsidiaries, has a receivables securitization agreement to permit securitized borrowings using its equipment installment plan receivables. In March 2021, UScellular borrowed $275 million under its receivables securitization agreement. As of March 31, 2021, UScellular has borrowed the full amount available under the receivables securitization agreement of $300 million. Amounts under the receivables securitization agreement may be repaid and reborrowed from time to time until December 2022, which may be extended from time to time as specified therein. See Note 9 — Debt in the Notes to Consolidated Financial Statements for additional information related to the receivables securitization agreement.

Financial Covenants

UScellular believes that it was in compliance with all of the financial covenants and requirements set forth in its revolving credit agreement, senior term loan credit agreement and receivables securitization agreement as of March 31, 2021.

Other Long-Term Financing

In 2020, UScellular issued $500 million of 6.25% Senior Notes due in 2069 and $500 million of 5.5% Senior Notes due in 2070. The proceeds from both issuances will be used for general corporate purposes, including but not limited to, the purchase of additional wireless spectrum licenses acquired in Auction 107, funding of capital expenditures and retirement of existing debt.

In April 2021, UScellular announced that it will redeem its outstanding $275 million of 7.25% Senior Notes due 2063. At time of redemption, $9 million of interest expense will be recorded related to unamortized debt issuance costs for these notes. The notes are expected to be redeemed on May 12, 2021, at a redemption price of 100% of the principal amount, including accrued and unpaid interest to the redemption date.

UScellular has an effective shelf registration statement on Form S-3 to issue senior or subordinated debt securities.

Capital Expenditures

Capital expenditures (i.e., additions to property, plant and equipment and system development expenditures; excludes wireless spectrum license additions), which include the effects of accruals and capitalized interest, for the three months ended March 31, 2021 and 2020, were as follows:

Capital Expenditures

(Dollars in millions)

Capital expenditures for the full year 2021 are expected to be between $775 million and $875 million. These expenditures are expected to be used principally for the following purposes:

▪Continue network modernization and 5G deployment;

▪Enhance and maintain UScellular's network coverage, including providing additional speed and capacity to accommodate increased data usage by current customers; and

▪Invest in information technology to support existing and new services and products.

UScellular intends to finance its capital expenditures for 2021 using primarily Cash flows from operating activities, existing cash balances and, if required, additional debt financing from its revolving credit agreement and/or other forms of financing.

Acquisitions, Divestitures and Exchanges

UScellular may be engaged from time to time in negotiations (subject to all applicable regulations) relating to the acquisition, divestiture or exchange of companies, properties or wireless spectrum licenses (including pursuant to FCC auctions). In general, UScellular may not disclose such transactions until there is a definitive agreement.

10

Other Obligations

UScellular will require capital for future spending on existing contractual obligations, including long-term debt obligations; lease commitments; commitments for device purchases, network facilities and transport services; agreements for software licensing; long-term marketing programs; Auction 107 relocation costs and accelerated relocation incentive payments; and other agreements to purchase goods or services.

Variable Interest Entities

UScellular consolidates certain “variable interest entities” as defined under GAAP. See Note 10 — Variable Interest Entities in the Notes to Consolidated Financial Statements for additional information related to these variable interest entities. UScellular 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

During the three months ended March 31, 2021, UScellular repurchased 54,900 Common Shares for $2 million at an average cost per share of $29.52. As of March 31, 2021, the total cumulative amount of UScellular Common Shares authorized to be repurchased is 4,452,000. For additional information related to the current repurchase authorization, see Unregistered Sales of Equity Securities and Use of Proceeds.

Off-Balance Sheet Arrangements

UScellular 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, results of operations, liquidity, capital expenditures or capital resources.

11

Consolidated Cash Flow Analysis

UScellular operates a capital-intensive business. UScellular makes substantial investments to acquire wireless spectrum 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-saving upgrades to UScellular’s networks. 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 UScellular's cash flow activities for the three months ended March 31, 2021 and 2020.

2021 Commentary

UScellular’s Cash, cash equivalents and restricted cash decreased $779 million. Net cash provided by operating activities was $124 million due to net income of $62 million adjusted for non-cash items of $167 million and distributions received from unconsolidated entities of $22 million. This was partially offset by changes in working capital items which decreased net cash by $127 million. The working capital changes were primarily influenced by the timing of vendor payments and annual associate bonus payments.

Cash flows used for investing activities were $1,388 million. Cash paid for additions to property, plant and equipment totaled $133 million. Cash payments for wireless spectrum license acquisitions were $1,253 million.

Cash flows provided by financing activities were $485 million, due primarily to $275 million borrowed under the receivables securitization agreement and $217 million borrowed under the term loan.

2020 Commentary

UScellular’s Cash, cash equivalents and restricted cash decreased $24 million. Net cash provided by operating activities was $342 million due to net income of $72 million adjusted for non-cash items of $228 million, distributions received from unconsolidated entities of $24 million, and changes in working capital items which increased net cash by $18 million. The working capital changes were primarily influenced by timing of vendor payments and collections of customer and agent receivables, partially offset by annual associate bonus payments, an increase in inventory and tax impacts from the CARES Act.

Cash flows used for investing activities were $342 million. Cash paid for additions to property, plant and equipment totaled $315 million. Cash payments for wireless spectrum license acquisitions were $26 million.

Cash flows used for financing activities were $24 million, due primarily to the repurchase of $21 million of Common Shares.

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. Notable balance sheet changes during 2021 were as follows:

Licenses

Licenses increased $1,286 million due primarily to wireless spectrum license rights acquired through Auction 107. See Note 7 — Intangible Assets in the Notes to Consolidated Financial Statements for additional information.

Accounts payable - Trade

Accounts payable - Trade decreased $101 million due primarily to vendor payment timing differences.

Accrued compensation

Accrued compensation decreased $42 million due primarily to associate bonus payments in March 2021.

Long-term debt, net

Long-term debt, net increased $492 million due primarily to $275 million borrowed under the receivables securitization agreement and $217 million borrowed under the term loan.

Supplemental Information Relating to Non-GAAP Financial Measures

UScellular sometimes uses information derived from consolidated financial information but not presented in its financial statements prepared in accordance with GAAP to evaluate the performance of its business. Specifically, UScellular has referred to the following measures in this Form 10-Q Report:

▪EBITDA

▪Adjusted EBITDA

▪Adjusted OIBDA

▪Free cash flow

Certain of these measures are considered “non-GAAP financial measures” under U.S. Securities and Exchange Commission Rules. Following are explanations of each of these measures.

EBITDA, Adjusted EBITDA and Adjusted OIBDA

EBITDA, Adjusted EBITDA and Adjusted OIBDA are defined as net income adjusted for the items set forth in the reconciliation below. EBITDA, Adjusted EBITDA and Adjusted OIBDA are not measures of financial performance under GAAP and should not be considered as alternatives to Net income or Cash flows from operating activities, as indicators of cash flows or as measures of liquidity. UScellular does not intend to imply that any such items set forth in the reconciliation below are non-recurring, infrequent or unusual; such items may occur in the future.

Management uses Adjusted EBITDA and Adjusted OIBDA as measurements of profitability, and therefore reconciliations to Net income and Operating income are deemed appropriate. Management believes Adjusted EBITDA and Adjusted OIBDA are useful measures of UScellular’s operating results before significant recurring non-cash charges, gains and losses, and other items as presented below as they provide additional relevant and useful information to investors and other users of UScellular’s financial data in evaluating the effectiveness of its operations and underlying business trends in a manner that is consistent with management’s evaluation of business performance. Adjusted EBITDA shows adjusted earnings before interest, taxes, depreciation, amortization and accretion, and gains and losses, while Adjusted OIBDA reduces this measure further to exclude Equity in earnings of unconsolidated entities and Interest and dividend income in order to more effectively show the performance of operating activities excluding investment activities. The following table reconciles EBITDA, Adjusted EBITDA and Adjusted OIBDA to the corresponding GAAP measures, Net income and Operating income.

14

Free Cash Flow

The following table presents Free cash flow, which is defined as Cash flows from operating activities less Cash paid for additions to property, plant and equipment. Free cash flow is a non-GAAP financial measure which UScellular believes may be useful to investors and other users of its financial information in evaluating liquidity, specifically, the amount of net cash generated by business operations after deducting Cash paid for additions to property, plant and equipment. 

	Three Months Ended March 31,
	2021		2020
(Dollars in millions)
Cash flows from operating activities (GAAP)	$	124	$	342
Less: Cash paid for additions to property, plant and equipment	133		315
Free cash flow (Non-GAAP)	$	(9)	$	27

Application of Critical Accounting Policies and Estimates

UScellular prepares its consolidated financial statements in accordance with GAAP. UScellular’s significant accounting policies are discussed in detail in Note 1 — Summary of Significant Accounting Policies and Recent Accounting Pronouncements, Note 2 — Revenue Recognition and Note 10 — Leases in the Notes to Consolidated Financial Statements and UScellular’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, both of which are included in UScellular’s Form 10-K for the year ended December 31, 2020. 

Regulatory Matters

5G Fund

On October 27, 2020, the FCC adopted rules creating the 5G Fund for Rural America, which will distribute up to $9 billion over ten years to bring 5G wireless broadband connectivity to rural America. The 5G Fund will be implemented through a two-phase competitive process, using multi-round auctions to award support. The winning bidders will be required to meet certain minimum speed requirements and interim and final deployment milestones. The order provides that the 5G Fund be in lieu of the previously proposed fund (the Phase II Connect America Mobility Fund) for the development of 4G LTE. The order also provides that over time a growing percentage of the legacy support a carrier receives must be used for 5G deployment.

UScellular cannot predict at this time when the 5G fund auction will occur, when the phase down period for its existing legacy support from the Federal USF will commence, or whether the 5G fund auction will provide opportunities to UScellular to offset any loss in existing support.

FCC Rulemaking - Restoring Internet Freedom

In December 2017, the FCC approved rules reversing or revising decisions made in the FCC’s 2015 Open Internet and Title II Order (Restoring Internet Freedom). The 2017 action reversed the FCC’s 2015 decision to reclassify Broadband Internet Access Services as telecommunications services subject to regulation under Title II of the Telecommunications Act. The 2017 action also reversed the FCC’s 2015 restrictions on blocking, throttling and paid prioritization, and modified transparency rules relating to such practices. Several parties filed suit in federal court challenging the 2017 actions. On October 1, 2019, the Court of Appeals for the D.C. Circuit issued an order reaffirming the FCC in most respects, but limiting the FCC's ability to preempt state and local net neutrality laws. On February 19, 2020, the FCC issued a Public Notice seeking comment on three issues under further consideration by the FCC based on a recent D.C. Circuit decision. On October 27, 2020, the FCC adopted an Order on Remand in response to the U.S. Court of Appeals for the D.C. Circuit’s remand on the three issues under further consideration by the FCC and found no basis to alter the FCC’s conclusions in the Restoring Internet Freedom Order.

A number of states, including certain states in which UScellular operates, have adopted or considered laws intended to reinstate aspects of the foregoing net neutrality regulations that were reversed or revised by the FCC in 2017. To the extent such laws are enacted, it is expected that legal proceedings will be pursued challenging such laws, subject now to the DC Circuit ruling limiting the FCC's preemptive authority in this matter. The new administration may also conduct rulemaking proceedings that may reinstate, in some form, net neutrality rules. UScellular cannot predict the outcome of any of these proceedings or the impact on its business.

Spectrum Auctions

On March 2, 2020, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.5 GHz band (Auction 105). On September 2, 2020, the FCC announced by public notice that UScellular was the provisional winning bidder for 243 wireless spectrum licenses for a purchase price of $14 million. The wireless spectrum licenses are expected to be granted by the FCC in 2021.

On August 7, 2020, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.7-3.98 GHz bands (Auction 107). On February 24, 2021, the FCC announced by public notice that UScellular was the provisional winning bidder for 254 wireless spectrum licenses for $1,283 million. UScellular paid $30 million of this amount in 2020 and the remainder in March 2021. Additionally, UScellular expects to capitalize costs of approximately $178 million related to the estimated relocation costs and accelerated relocation incentive payments. The wireless spectrum licenses from Auction 107 are expected to be granted by the FCC in 2021. The spectrum must be cleared by incumbent providers before UScellular can access it. UScellular does not expect to have access to this spectrum until late 2023. Combined with prior mid-band purchases in Auction 105, UScellular will have mid-band spectrum in nearly all of its operating footprint, covering approximately 95% of subscribers.

Each of the following risks could have a material adverse effect on UScellular’s business, financial condition or results of operations. However, such factors are not necessarily all of the important factors that could cause actual results, performance or achievements to differ materially from those expressed in, or implied by, the forward-looking statements contained in this document. Other unknown or unpredictable factors also could have material adverse effects on future results, performance or achievements. UScellular undertakes no obligation to update publicly any forward-looking statements whether as a result of new information, future events or otherwise. You should carefully consider the Risk Factors in UScellular’s Form 10-K for the year ended December 31, 2020, the following factors and other information contained in, or incorporated by reference into, this Form 10-Q to understand the material risks relating to UScellular’s business, financial condition or results of operations.

Operational Risk Factors

▪Intense competition involving products, services, pricing and network speed and technologies could adversely affect UScellular’s revenues or increase its costs to compete.

▪Changes in roaming practices or other factors could cause UScellular's roaming revenues to decline from current levels, roaming expenses to increase from current levels and/or impact UScellular's ability to service its customers in geographic areas where UScellular does not have its own network, which could have an adverse effect on UScellular's business, financial condition or results of operations.

▪A failure by UScellular 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 UScellular’s business, financial condition or results of operations.

▪An inability to attract people of outstanding talent throughout all levels of the organization, to develop their potential through education and assignments, and to retain them by keeping them engaged, challenged and properly rewarded could have an adverse effect on UScellular's business, financial condition or results of operations.

▪UScellular’s smaller scale relative to larger competitors that may have greater financial and other resources than UScellular could cause UScellular to be unable to compete successfully, which could adversely affect its business, financial condition or results of operations.

▪Changes in various business factors, including changes in demand, consumer preferences and perceptions, price competition, churn from customer switching activity and other factors, could have an adverse effect on UScellular’s business, financial condition or results of operations.

▪Advances or changes in technology could render certain technologies used by UScellular obsolete, could put UScellular at a competitive disadvantage, could reduce UScellular’s revenues or could increase its costs of doing business.

▪Complexities associated with deploying new technologies present substantial risk and UScellular investments in unproven technologies may not produce the benefits that UScellular expects.

▪Costs, integration problems or other factors associated with acquisitions, divestitures or exchanges of properties or wireless spectrum licenses and/or expansion of UScellular’s business could have an adverse effect on UScellular’s business, financial condition or results of operations.

▪A failure by UScellular to complete significant network construction and systems implementation activities as part of its plans to improve the quality, coverage, capabilities and capacity of its network, support and other systems and infrastructure could have an adverse effect on its operations.

▪Difficulties involving third parties with which UScellular does business, including changes in UScellular's relationships with or financial or operational difficulties of key suppliers or independent agents and third-party national retailers who market UScellular’s services, could adversely affect UScellular's business, financial condition or results of operations.

▪A failure by UScellular to maintain flexible and capable telecommunication networks or information technology, or a material disruption thereof, could have an adverse effect on UScellular’s business, financial condition or results of operations.

17

Financial Risk Factors

▪Uncertainty in UScellular’s future cash flow and liquidity or the inability to access capital, deterioration in the capital markets, other changes in UScellular’s performance or market conditions, changes in UScellular’s credit ratings or other factors could limit or restrict the availability of financing on terms and prices acceptable to UScellular, which could require UScellular to reduce its construction, development or acquisition programs, reduce the amount of wireless spectrum licenses acquired, and/or reduce or cease share repurchases.

▪UScellular has a significant amount of indebtedness which could adversely affect its financial performance and in turn adversely affect its ability to make payments on its indebtedness, comply with terms of debt covenants and incur additional debt.

▪UScellular’s assets and revenue are concentrated in the U.S. wireless telecommunications industry. Consequently, its operating results may fluctuate based on factors related primarily to conditions in this industry.

▪UScellular has significant investments in entities that it does not control. Losses in the value of such investments could have an adverse effect on UScellular’s financial condition or results of operations.

Regulatory, Legal and Governance Risk Factors

▪Failure by UScellular to timely or fully comply with any existing applicable legislative and/or regulatory requirements or changes thereto could adversely affect UScellular’s business, financial condition or results of operations.

▪UScellular receives significant regulatory support, and is also subject to numerous surcharges and fees from federal, state and local governments – the applicability and the amount of the support and fees are subject to great uncertainty, including the ability to pass through certain fees to customers, and this uncertainty could have an adverse effect on UScellular’s business, financial condition or results of operations.

▪Settlements, judgments, restraints on its current or future manner of doing business and/or legal costs resulting from pending and future litigation could have an adverse effect on UScellular’s business, financial condition or results of operations.

▪The possible development of adverse precedent in litigation or conclusions in professional studies to the effect that radio frequency emissions from wireless devices and/or cell sites cause harmful health consequences, including cancer or tumors, or may interfere with various electronic medical devices such as pacemakers, could have an adverse effect on UScellular's business, financial condition or results of operations.

▪Claims of infringement of intellectual property and proprietary rights of others, primarily involving patent infringement claims, could prevent UScellular from using necessary technology to provide products or services or subject UScellular to expensive intellectual property litigation or monetary penalties, which could have an adverse effect on UScellular’s business, financial condition or results of operations.

▪There are potential conflicts of interests between TDS and UScellular.

▪Certain matters, such as control by TDS and provisions in the UScellular Restated Certificate of Incorporation, may serve to discourage or make more difficult a change in control of UScellular or have other consequences.

General Risk Factors

▪UScellular has experienced, and in the future expects to experience, cyber-attacks or other breaches of network or information technology security of varying degrees on a regular basis, which could have an adverse effect on UScellular's business, financial condition or results of operations.

▪Disruption in credit or other financial markets, a deterioration of U.S. or global economic conditions or other events could, among other things, impede UScellular’s access to or increase the cost of financing its operating and investment activities and/or result in reduced revenues and lower operating income and cash flows, which would have an adverse effect on UScellular’s business, financial condition or results of operations.

▪The impact of public health emergencies, such as the COVID-19 pandemic, on UScellular's business is uncertain, but depending on duration and severity could have a material adverse effect on UScellular's business, financial condition or results of operations.

18

Notes to Consolidated Financial Statements

Note 1 Basis of Presentation

United States Cellular Corporation (UScellular), a Delaware Corporation, is an 82%-owned subsidiary of Telephone and Data Systems, Inc. (TDS).

The accounting policies of UScellular 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 UScellular, subsidiaries in which it has a controlling financial interest, general partnerships in which UScellular has a majority partnership interest and certain entities in which UScellular has a variable interest that requires consolidation under GAAP. Intercompany accounts and transactions have been eliminated.

The unaudited consolidated financial statements included herein have been prepared by UScellular pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. However, UScellular believes that the disclosures included herein are adequate to make the information presented not misleading. Certain numbers included herein are rounded to millions for ease of presentation; however, certain calculated amounts and percentages are determined using the unrounded numbers. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in UScellular’s Annual Report on Form 10-K (Form 10-K) for the year ended December 31, 2020.

The accompanying unaudited consolidated financial statements contain all adjustments (consisting of normal recurring items, unless otherwise disclosed) necessary for the fair statement of UScellular’s financial position as of March 31, 2021 and December 31, 2020 and its results of operations, cash flows and changes in equity for the three months ended March 31, 2021 and 2020. The Consolidated Statement of Comprehensive Income was not included because comprehensive income for the three months ended March 31, 2021 and 2020, equaled net income. These results are not necessarily indicative of the results to be expected for the full year. UScellular has not changed its significant accounting and reporting policies from those disclosed in its Form 10-K for the year ended December 31, 2020.

Note 2 Revenue Recognition

Disaggregation of Revenue

In the following table, UScellular's revenues are disaggregated by type of service, which represents the relevant categorization of revenues for UScellular, and timing of recognition. Service revenues are recognized over time and Equipment sales are point in time.  

	Three Months Ended March 31,
	2021		2020
(Dollars in millions)
Revenues from contracts with customers:
Retail service	$	685	$	671
Inbound roaming	28		37
Other service	38		35
Service revenues from contracts with customers	751		743
Equipment sales	252		201
Total revenues from contracts with customers	1,003		944
Operating lease income	20		19
Total operating revenues	$	1,023	$	963

Contract Balances

The following table provides balances for contract assets from contracts with customers, which are recorded in Other current assets and Other assets and deferred charges in the Consolidated Balance Sheet, and contract liabilities from contracts with customers, which are recorded in Customer deposits and deferred revenues and Other deferred liabilities and credits in the Consolidated Balance Sheet.

	March 31, 2021		December 31, 2020
(Dollars in millions)
Contract assets	$	11	$	10
Contract liabilities	$	185	$	171

Revenue recognized related to contract liabilities existing at January 1, 2021 was $97 million for the three months ended March 31, 2021.

Transaction price allocated to the remaining performance obligations

The following table includes estimated service revenues expected to be recognized related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. These estimates represent service revenues to be recognized when wireless services are delivered to customers pursuant to service plan contracts and under certain roaming agreements with other carriers. These estimates are based on contracts in place as of March 31, 2021 and may vary from actual results. As practical expedients, revenue related to contracts of less than one year, generally month-to-month contracts, and contracts with a fixed per-unit price and variable quantity, are excluded from these estimates. 

	Service Revenues
(Dollars in millions)
Remainder of 2021	$	209
2022	112
Thereafter	128
Total	$	449

Contract Cost Assets

UScellular expects that commission fees paid as a result of obtaining contracts are recoverable and therefore UScellular defers and amortizes these costs. As a practical expedient, costs with an amortization period of one year or less are expensed as incurred. The contract cost asset balance related to commission fees and other costs was $123 million at March 31, 2021, and $124 million at December 31, 2020, and was recorded in Other assets and deferred charges in the Consolidated Balance Sheet. Deferred commission fees are amortized based on the timing of transfer of the goods or services to which the assets relate, typically the contract term. Amortization of contract cost assets was $25 million and $27 million for the three months ended March 31, 2021 and 2020, respectively, and was included in Selling, general and administrative expenses.

Note 3 Fair Value Measurements

As of March 31, 2021 and December 31, 2020, UScellular did not have any material 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 assets or Level 1 assets.

UScellular 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, 2021				December 31, 2020
		Book Value		Fair Value		Book Value		Fair Value
(Dollars in millions)
Long-term debt
Retail	2	$	1,917	$	1,963	$	1,917	$	1,962
Institutional	2	535		661		535		707
Other	2	598		598		106		106

Long-term debt excludes lease obligations, the current portion of Long-term debt and debt financing costs. The fair value of “Retail” Long-term debt was estimated using market prices for the 7.25% 2063 Senior Notes, 7.25% 2064 Senior Notes, 6.95% Senior Notes, 6.25% Senior Notes and 5.5% Senior Notes. UScellular’s “Institutional” debt consists of the 6.7% Senior Notes which are traded over the counter. UScellular’s “Other” debt consists of a senior term loan credit agreement and receivables securitization agreement. UScellular 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 1.31% to 4.48% and 1.35% to 3.75% at March 31, 2021 and December 31, 2020, respectively.

The fair values of Cash and cash equivalents, restricted cash and Short-term investments approximate their book values due to the short-term nature of these financial instruments.

Note 4 Equipment Installment Plans

UScellular sells devices to customers under equipment installment plans over a specified time period. For certain equipment installment plans, 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.

The following table summarizes equipment installment plan receivables.

	March 31, 2021		December 31, 2020
(Dollars in millions)
Equipment installment plan receivables, gross	$	1,013	$	1,007
Allowance for credit losses	(72)		(78)
Equipment installment plan receivables, net	$	941	$	929
Net balance presented in the Consolidated Balance Sheet as:
Accounts receivable — Customers and agents (Current portion)	$	596	$	590
Other assets and deferred charges (Non-current portion)	345		339
Equipment installment plan receivables, net	$	941	$	929

UScellular uses various inputs, including internal data, information from credit bureaus and other sources, to evaluate the credit profiles of its customers. From this evaluation, a credit class is assigned to the customer that determines the number of eligible lines, the amount of credit available, and the down payment requirement, if any. These credit classes are grouped into four credit categories: lowest risk, lower risk, slight risk and higher risk. A customer's assigned credit class is reviewed periodically and a change is made, if appropriate. An equipment installment plan billed amount is considered past due if not paid within 30 days. The balance and aging of the equipment installment plan receivables on a gross basis by credit category were as follows:

	March 31, 2021										December 31, 2020
	Lowest Risk		Lower Risk		Slight Risk		Higher Risk		Total		Lowest Risk		Lower Risk		Slight Risk		Higher Risk		Total
(Dollars in millions)
Unbilled	$	826	$	99	$	24	$	8	$	957	$	819	$	98	$	22	$	9	$	948
Billed — current	35		5		1		1		42		36		5		1		1		43
Billed — past due	7		4		2		1		14		8		5		2		1		16
Total	$	868	$	108	$	27	$	10	$	1,013	$	863	$	108	$	25	$	11	$	1,007

The balance of the equipment installment plan receivables as of March 31, 2021 on a gross basis by year of origination were as follows:

	2018		2019		2020		2021		Total
(Dollars in millions)
Lowest Risk	$	15	$	202	$	484	$	167	$	868

Higher Risk	0		1		5		4		10
Total	$	17	$	224	$	562	$	210	$	1,013

Activity for the three months ended March 31, 2021 and 2020, in the allowance for credit losses for equipment installment plan receivables was as follows:

	March 31, 2021		March 31, 2020
(Dollars in millions)
Allowance for credit losses, beginning of period	$	78	$	84

Note 5 Income Taxes

The effective tax rate on Income before income taxes for the three months ended March 31, 2021 and 2020, was 30.4% and 5.0%, respectively. The higher effective tax rate in 2021 as compared to 2020 is due primarily to the income tax benefits of the CARES Act included in the 2020 tax rate, which do not recur as benefits in the 2021 tax rate.

Note 6 Earnings Per Share

Basic earnings per share attributable to UScellular shareholders is computed by dividing Net income attributable to UScellular shareholders by the weighted average number of Common Shares outstanding during the period. Diluted earnings per share attributable to UScellular shareholders is computed by dividing Net income attributable to UScellular 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 the exercise of outstanding stock options and the vesting of performance and restricted stock units.

The amounts used in computing basic and diluted earnings per share attributable to UScellular shareholders were as follows:

	Three Months Ended March 31,
	2021		2020
(Dollars and shares in millions, except per share amounts)
Net income attributable to UScellular shareholders	$	60	$	71
Weighted average number of shares used in basic earnings per share	86		86
Effects of dilutive securities	2		2
Weighted average number of shares used in diluted earnings per share	88		88
Basic earnings per share attributable to UScellular shareholders	$	0.70	$	0.82
Diluted earnings per share attributable to UScellular shareholders	$	0.69	$	0.81

Certain Common Shares issuable upon the exercise of stock options or vesting of performance and restricted stock units were not included in weighted average diluted shares outstanding for the calculation of Diluted earnings per share attributable to UScellular shareholders because their effects were antidilutive. The number of such Common Shares excluded was less than 1 million and 1 million for the three months ended March 31, 2021 and 2020, respectively.

Note 7 Intangible Assets

Activity related to Licenses for the three months ended March 31, 2021, is presented below:

	Licenses
(Dollars in millions)
Balance at December 31, 2020	$	2,629
Acquisitions	1,283
Capitalized interest	3
Balance at March 31, 2021	$	3,915

In February 2021, the FCC announced by way of public notice that UScellular was the provisional winning bidder for 254 wireless spectrum licenses in the 3.7-3.98 GHz bands (Auction 107) for $1,283 million. UScellular paid $30 million of this amount in 2020 and the remainder in March 2021. Additionally, UScellular expects to capitalize costs of approximately $178 million related to the estimated relocation costs and accelerated relocation incentive payments. The wireless spectrum licenses from Auction 107 are expected to be granted by the FCC in 2021. The spectrum must be cleared by incumbent providers before UScellular can access it. UScellular does not expect to have access to this spectrum until late 2023.

Note 8 Investments in Unconsolidated Entities

Investments in unconsolidated entities consist of amounts invested in entities in which UScellular holds a noncontrolling interest. UScellular’s Investments in unconsolidated entities are accounted for using either the equity method or measurement alternative method as shown in the table below. The carrying value of measurement alternative method investments represents cost minus any impairments plus or minus any observable price changes.

	March 31, 2021		December 31, 2020
(Dollars in millions)
Equity method investments	$	447	$	428
Measurement alternative method investments	8		7
Total investments in unconsolidated entities	$	455	$	435

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

	Three Months Ended March 31,

Note 9 Debt

Term Loan Agreement

The following table summarizes the term loan credit agreement as of March 31, 2021:

(Dollars in millions)
Maximum borrowing capacity	$	300
Amount borrowed	$	300
Amount available for use	$	0

Borrowings under the term loan bear interest at a rate of LIBOR plus 2.25%. Principal reductions are due and payable in quarterly installments of $0.75 million beginning in September 2021. The remaining unpaid balance will be due and payable in June 2027.

UScellular believes that it was in compliance with all of the financial covenants and other requirements set forth in its senior term loan credit agreement as of March 31, 2021.

Receivables Securitization Agreement

At March 31, 2021, UScellular had a receivables securitization agreement for securitized borrowings using its equipment installment receivables for general corporate purposes. Amounts under the receivables securitization agreement may be borrowed, repaid and reborrowed from time to time until maturity in December 2022, which may be extended from time to time as specified therein. The outstanding borrowings bear interest at floating rates. In March 2021, UScellular borrowed $275 million under its receivables securitization agreement. As of March 31, 2021, UScellular has borrowed the full amount available under the receivables securitization agreement of $300 million. UScellular believes that it was in compliance with all of the financial covenants and other requirements set forth in its receivables securitization agreement as of March 31, 2021. As of March 31, 2021, the USCC Master Note Trust held $446 million of assets available to be pledged as collateral for the receivables securitization agreement.

Other Long-Term Debt

In April 2021, UScellular announced that it will redeem its outstanding $275 million of 7.25% Senior Notes due 2063. At time of redemption, $9 million of interest expense will be recorded related to unamortized debt issuance costs related to the notes. The notes are expected to be redeemed on May 12, 2021, at a redemption price of 100% of the principal amount, including accrued and unpaid interest to the redemption date.

Note 10 Variable Interest Entities

Consolidated VIEs

UScellular consolidates VIEs in which it has a controlling financial interest as defined by GAAP and is therefore deemed the primary beneficiary. UScellular reviews the criteria for a controlling financial interest 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 this Form 10-Q and UScellular’s Form 10-K for the year ended December 31, 2020.

UScellular formed USCC EIP LLC (Seller/Sub-Servicer), USCC Receivables Funding LLC (Transferor) and the USCC Master Note Trust (Trust), collectively the special purpose entities (SPEs), to facilitate a securitized borrowing using its equipment installment plan receivables. Under a Receivables Sale Agreement, UScellular wholly-owned, majority-owned and unconsolidated entities, collectively referred to as “affiliated entities”, transfer device equipment installment plan contracts to the Seller/Sub-Servicer. The Seller/Sub-Servicer aggregates device equipment installment plan contracts, and performs servicing, collection and all other administrative activities related to accounting for the equipment installment plan contracts. The Seller/Sub-Servicer sells the eligible equipment installment plan receivables to the Transferor, a bankruptcy remote entity, which subsequently sells the receivables to the Trust. The Trust, which is bankruptcy remote and isolated from the creditors of UScellular, will be responsible for issuing asset-backed variable funding notes (Notes), which are collateralized by the equipment installment plan receivables owned by the Trust. Given that UScellular has the power to direct the activities of these SPEs, and that these SPEs lack sufficient equity to finance their activities, UScellular is deemed to have a controlling financial interest in the SPEs and, therefore, consolidates them. All transactions with third parties (e.g., issuance of the asset-backed variable funding notes) will be accounted for as a secured borrowing due to the pledging of equipment installment plan contracts as collateral, significant continuing involvement in the transferred assets, subordinated interests of the cash flows, and continued evidence of control of the receivables. 

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

▪Advantage Spectrum, L.P. (Advantage Spectrum) and Sunshine Spectrum, Inc., the general partner of Advantage Spectrum; 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. 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, an indirect UScellular subsidiary, to sell or lease certain wireless spectrum 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, UScellular has the most significant level of exposure to the variability associated with the economic performance of the VIEs, indicating that UScellular is the primary beneficiary of the VIEs. Therefore, in accordance with GAAP, these VIEs are consolidated.

UScellular also consolidates other VIEs that are limited partnerships that provide wireless service. A limited partnership is a variable interest entity unless the limited partners hold substantive participating rights or kick-out rights over the general partner. For certain limited partnerships, UScellular 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, these limited partnerships also are recognized as VIEs and are consolidated under the variable interest model.

32

The following table presents the classification and balances of the consolidated VIEs’ assets and liabilities in UScellular’s Consolidated Balance Sheet.

Unconsolidated VIEs

UScellular 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.

UScellular’s total investment in these unconsolidated entities was $5 million at both March 31, 2021 and December 31, 2020, and is included in Investments in unconsolidated entities in UScellular’s Consolidated Balance Sheet. The maximum exposure from unconsolidated VIEs is limited to the investment held by UScellular in those entities. 

Other Related Matters

UScellular made contributions, loans or advances to its VIEs totaling $30 million and $69 million, during the three months ended March 31, 2021 and 2020, respectively, of which $10 million in 2021 and $55 million in 2020, are related to USCC EIP LLC as discussed above. UScellular 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 wireless spectrum licenses granted in various auctions. UScellular may finance such amounts with a combination of cash on hand, borrowings under its revolving credit or receivables securitization agreements and/or other long-term debt. There is no assurance that UScellular will be able to obtain additional financing on commercially reasonable terms or at all to provide such financial support.

The limited partnership agreement of Advantage Spectrum also provides the general partner with a put option whereby the general partner may require the limited partner, a subsidiary of UScellular, to purchase its interest in the limited partnership. The general partner’s put option related to its interest in Advantage Spectrum will be exercisable in the third quarter of 2021, and if not exercised at that time, will be exercisable in 2022. The greater of the carrying value of the general partner's investment or the value of the put option, net of any borrowings due to UScellular, is recorded as Noncontrolling interests with redemption features in UScellular’s Consolidated Balance Sheet. Also in accordance with GAAP, minority share of income or changes in the redemption value of the put option, net of interest accrued on the loans, are recorded as a component of Net income attributable to noncontrolling interests, net of tax, in UScellular’s Consolidated Statement of Operations.

Additional Required Information

Controls and Procedures

Evaluation of Disclosure Controls and Procedures

UScellular 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 UScellular’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 Rules 13a-15(b), UScellular 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 UScellular’s disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Based on this evaluation, UScellular’s principal executive officer and principal financial officer concluded that UScellular’s disclosure controls and procedures were effective as of March 31, 2021, at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

There have been no changes in internal controls over financial reporting that have occurred during the three months ended March 31, 2021, that have materially affected, or are reasonably likely to materially affect, UScellular’s internal control over financial reporting.

Legal Proceedings

In April 2018, the United States Department of Justice (DOJ) notified UScellular and its parent, TDS, that it was conducting inquiries of UScellular and TDS under the federal False Claims Act relating to UScellular’s participation in wireless spectrum license auctions 58, 66, 73 and 97 conducted by the FCC. UScellular is/was a limited partner in several limited partnerships which qualified for the 25% bid credit in each auction. The investigation arose from civil actions under the Federal False Claims Act brought by private parties in the U.S. District Court for the Western District of Oklahoma. In November and December 2019, following the DOJ’s investigation, the DOJ informed UScellular and TDS that it would not intervene in the above-referenced actions. Subsequently, the private party plaintiffs filed amended complaints in both actions in the U.S. District Court for the Western District of Oklahoma and are continuing the action on their own. In July 2020, these actions were transferred to the U.S. District Court for the District of Columbia. UScellular believes that its arrangements with the limited partnerships and the limited partnerships’ participation in the FCC auctions complied with applicable law and FCC rules. At this time, UScellular cannot predict the outcome of any proceeding.

Refer to the disclosure under Legal Proceedings in UScellular’s Form 10-K for the year ended December 31, 2020, for additional information. There have been no material changes to such information since December 31, 2020.

Unregistered Sales of Equity Securities and Use of Proceeds

In November 2009, UScellular announced by Form 8-K that the Board of Directors of UScellular authorized the repurchase of up to 1,300,000 additional Common Shares on an annual basis beginning in 2009 and continuing each year thereafter, on a cumulative basis. In December 2016, the UScellular Board amended this authorization to provide that, beginning on January 1, 2017, the increase in the authorized repurchase amount with respect to a particular year will be any amount from zero to 1,300,000 Common Shares, as determined by the Pricing Committee of the Board of Directors, and that if the Pricing Committee did not specify an additional amount for any year, such additional amount would be zero for such year. The Pricing Committee has not specified any increase in the authorization since that time. The Pricing Committee also was authorized to decrease the cumulative amount of the authorization at any time, but has not taken any action to do so at this time. The authorization provides that share repurchases will be made pursuant to open market purchases, block purchases, private purchases, or otherwise, depending on market prices and other conditions. This authorization does not have an expiration date. UScellular did not determine to terminate the foregoing Common Share repurchase program, as amended, or cease making further purchases thereunder, during the first quarter of 2021.

The following table provides certain information with respect to all purchases made by or on behalf of UScellular, and any open market purchases made by any "affiliated purchaser" (as defined by the SEC) of UScellular, of UScellular Common Shares during the quarter covered by this Form 10-Q.
