Executive Overview
The following discussion and analysis compares United States Cellular Corporation’s (UScellular) financial results for the three and six months ended June 30, 2021, to the three and six months ended June 30, 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.

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.

N/M - Percentage change not meaningful
Total postpaid handset net additions decreased for the three months ended June 30, 2021, when compared to the same period last year due primarily to an increase in defections resulting from higher consumer switching activity which was depressed in 2020 due to COVID-19. Partially offsetting the increase in defections was an increase in gross additions.
Total postpaid handset net losses decreased for the six months ended June 30, 2021, when compared to the same period last year due primarily to an increase in gross additions as a result of higher consumer switching activity in 2021, as well as a decrease in non-pay defections. Partially offsetting the decrease was an increase in voluntary defections.
Total postpaid connected device net additions decreased for the three and six months ended June 30, 2021, when compared to the same period last year, in substantial part, due to lower demand for internet related products as a result of a reduction in COVID-related funding vehicles, many of which are connected to government subsidies.

Postpaid ARPU and Postpaid ARPA increased for the three and six months ended June 30, 2021, when compared to the same period last year, due to (i) an increase in regulatory recovery revenues, (ii) favorable plan and product offering mix, (iii) an increase in device protection plan revenues, and (iv) an increase in overage fees which were waived in Q2 2020 to assist customers during the COVID-19 pandemic. These increases were partially offset by an increase in promotional discounts.

Operating Revenues
Three Months Ended June 30, 2021 and 2020
(Dollars in millions)
Operating Revenues
Six Months Ended June 30, 2021 and 2020
(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 and six months ended June 30, 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 and six months ended June 30, 2021, primarily driven by lower data revenues resulting from lower usage and lower rates. UScellular expects inbound roaming revenues to continue to decline during 2021 relative to prior year levels.
Other service revenues increased for the three and six months ended June 30, 2021, resulting from increases in tower rental revenues and miscellaneous other service revenues.
Equipment sales revenues increased for the three and six months ended June 30, 2021, due primarily to an increase in the volume of smartphone and accessory sales, partially offset by an increase in promotional activity.
In recent periods, wireless service providers have increased promotional aggressiveness to attract new customers and retain existing customers. Operating revenues and Operating income may be negatively impacted in future periods by the competitive need to offer increased promotional discounts to new and existing customers.

Table of Contents
System operations expenses
System operations expenses increased for the three and six months ended June 30, 2021, due to higher circuit costs as well as an increase in cell site rent and maintenance expense.
Cost of equipment sold
Cost of equipment sold increased for the three and six months ended June 30, 2021, due primarily to an increase in the volume of smartphone and accessory sales.
Selling, general and administrative expenses
Selling, general and administrative expenses increased for the three months ended June 30, 2021, due primarily to increases in system development costs and Federal USF expense.
Selling, general and administrative expenses decreased for the six months ended June 30, 2021, due primarily to reductions in (i) bad debts expense driven by fewer non-pay customers as a result of better credit mix and improved customer payment behavior, and (ii) advertising expenses. This was partially offset by increases in system development costs and Federal USF expense.

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 $22 million and $20 million for the three months ended June 30, 2021 and 2020, respectively and $41 million and $42 million for the six months ended June 30, 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 increased for the three months ended June 30, 2021, driven primarily by a higher average investment balance. Interest and dividend income decreased for the six months ended June 30, 2021, driven primarily by lower interest rates.
Interest expense
Interest expense increased for the three and six months ended June 30, 2021, primarily as a result of (i) the issuance of $500 million of 6.25% Senior Notes in August 2020 and $500 million of 5.50% Senior Notes in both December 2020 and May 2021 and (ii) the write off of $20 million of unamortized debt issuance costs related to $575 million of Senior Notes that were redeemed during the three months ended June 30, 2021. See Note 9 — Debt in the Notes to Consolidated Financial Statements for additional information.

Income tax expense
The effective tax rate on Income before income taxes for the three months ended June 30, 2021 and 2020, was (42.0)% and 5.5%, respectively. The effective tax rate for the three months ended June 30, 2021 was lower due primarily to the reduction of tax accruals resulting from expirations of state statute of limitations for prior years. The decrease was partially offset by 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 effective tax rate on Income before income taxes for the six months ended June 30, 2021 and 2020, was 14.5% and 5.2%, respectively. The effective tax rate for the six months ended June 30, 2021 was higher 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 increase was partially offset by the reduction of tax accruals resulting from expirations of state statute of limitations for prior tax years.

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, term loan and receivables securitization agreements, 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 June 30, 2021, there were no outstanding borrowings under the revolving credit agreement, and UScellular's unused borrowing capacity was $300 million.
In July 2021, UScellular amended and restated its revolving credit agreement. The maturity date of the agreement was extended to July 2026 and the consolidated leverage ratio, as defined in the agreement, may not be greater than 3.75 to 1.00 as of the end of any fiscal quarter. There were no significant changes to other terms of the revolving credit agreement.

Table of Contents
Term Loan Agreement
In February 2021, UScellular borrowed $217 million under its senior term loan credit agreement. As of June 30, 2021, UScellular has borrowed the full amount available under the senior term loan credit agreement of $300 million.
In July 2021, UScellular amended and restated its term loan agreement to allow for an additional $200 million of borrowing capacity.
See Note 9 — Debt in the Notes to Consolidated Financial Statements for additional information related to the senior term loan agreement.
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 an additional $275 million under its receivables securitization agreement. In June 2021, UScellular repaid $200 million of the outstanding borrowing.
In June 2021, UScellular increased the borrowing capacity under the receivables securitization agreement to $450 million. As of June 30, 2021, the outstanding borrowings under the agreement were $100 million and the unused capacity under the agreement was $350 million, subject to sufficient collateral to satisfy the asset borrowing base provisions of the agreement. 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.
In July 2021, UScellular amended the receivables securitization agreement. The consolidated leverage ratio, as defined in the agreement, may not be greater than 3.75 to 1.00 as of the end of any fiscal quarter. There were no significant changes to other terms of the receivable 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 June 30, 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 March 2070. The proceeds from both issuances were for general corporate purposes, including but not limited to, the purchase of additional wireless spectrum licenses acquired in Auction 107, funding of capital expenditures, including in connection with 5G buildout projects and retirement of existing debt.
In May 2021, UScellular issued $500 million of 5.5% Senior Notes due in June 2070. The proceeds from the issuance were used for general corporate purposes, including but not limited to, the repayment of other debt, the purchase of additional spectrum and the funding of capital expenditures, including in connection with 5G buildout projects.
In May 2021, UScellular redeemed its outstanding $275 million of 7.25% Senior Notes due 2063. At time of redemption, $9 million of interest expense was recorded related to unamortized debt issuance costs for these notes. The notes were redeemed at a price of 100% of the principal amount, including accrued and unpaid interest to the redemption date.
In June 2021, UScellular redeemed its outstanding $300 million of 7.25% Senior Notes due 2064. At time of redemption, $10 million of interest expense was recorded related to unamortized debt issuance costs for these notes. The notes were redeemed at a price of 100% of the principal amount, including accrued and unpaid interest to the redemption date.
In August 2021, UScellular announced that it will redeem its outstanding $342 million of 6.95% Senior Notes due 2060. At time of redemption, $11 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 September 1, 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, preferred shares and depositary shares.
Credit Ratings
In August 2021, Moody’s lowered its rating for UScellular’s senior unsecured notes from Ba1 to Ba2. This downgrade is due primarily to the impact of the financing activities noted above that increase the capacity of debt facilities that are structurally senior to UScellular’s senior unsecured notes.

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 six months ended June 30, 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, term loan and receivables securitization agreements 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.
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 six months ended June 30, 2021, UScellular repurchased 54,900 Common Shares for $2 million at an average cost per share of $29.52. As of June 30, 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.

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 six months ended June 30, 2021 and 2020.
2021 Commentary
UScellular’s Cash, cash equivalents and restricted cash decreased $994 million. Net cash provided by operating activities was $363 million due to net income of $97 million adjusted for non-cash items of $355 million and distributions received from unconsolidated entities of $79 million including $32 million in distributions from the LA Partnership. This was partially offset by changes in working capital items which decreased net cash by $168 million. The working capital changes were primarily influenced by the timing of vendor payments, increases in inventory, and the timing of annual associate bonus payments.
Cash flows used for investing activities were $1,534 million. Cash paid for additions to property, plant and equipment totaled $281 million. Cash payments for wireless spectrum license acquisitions were $1,253 million.
Cash flows provided by financing activities were $177 million, due primarily to the issuance of $500 million of 5.5% Senior Notes, $275 million borrowed under the receivables securitization agreement, and $217 million borrowed under the term loan. These were partially offset by the redemption of $575 million of UScellular Senior Notes and a $200 million repayment on the receivables securitization agreement.
2020 Commentary
UScellular’s Cash, cash equivalents and restricted cash increased $145 million. Net cash provided by operating activities was $692 million due to net income of $141 million adjusted for non-cash items of $441 million, distributions received from unconsolidated entities of $90 million including $43 million in distributions from the LA Partnership, and changes in working capital items which increased net cash by $20 million. The working capital changes were primarily influenced by timing of vendor payments and collections of customer and agent receivables, partially offset by tax impacts from the CARES Act and annual associate bonus payments.
Cash flows used for investing activities were $631 million. Cash paid for additions to property, plant and equipment totaled $471 million. Cash payments for wireless spectrum license acquisitions were $144 million.
Cash flows provided by financing activities were $84 million, reflecting the $125 million borrowed under the receivables securitization agreement, partially offset by the repurchase of $23 million of Common Shares.

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:
Inventory, net
Inventory, net increased $37 million due primarily to an increase in the volume of inventory.
Licenses
Licenses increased $1,288 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 $94 million due primarily to vendor payment timing differences.
Accrued compensation
Accrued compensation decreased $29 million due primarily to associate bonus payments in March 2021.
Long-term debt, net
The following table presents the components of the $221 million increase in Long-term debt, net:

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.

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.

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 have not yet been granted by the FCC.
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. The wireless spectrum licenses from Auction 107 were granted by the FCC in July 2021. Additionally, UScellular expects to be obligated to pay approximately $178 million in total from 2021 through 2024 related to relocation costs and accelerated relocation incentive payments. Such additional costs were accrued and capitalized at the time the licenses were granted, which occurred after the period ended June 30, 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.
On June 9, 2021, the FCC released a Public Notice establishing procedures for an auction offering wireless spectrum licenses in the 3.45-3.55 GHz band (Auction 110). UScellular filed an application to participate in Auction 110 on July 19, 2021. Upfront payments are due on September 2, 2021 and bidding will commence on October 5, 2021.

▪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.

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.

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 June 30, 2021 and December 31, 2020 and its results of operations and changes in equity for the three and six months ended June 30, 2021 and 2020, and its cash flows for the six months ended June 30, 2021 and 2020. The Consolidated Statement of Comprehensive Income was not included because comprehensive income for the six months ended June 30, 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.

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.

| June 30, 2021 |  | December 31, 2020
(Dollars in millions) |  |  |
Contract assets | $ | 11 |  |  | $ | 10 |
Contract liabilities | $ | 183 |  |  | $ | 171 |

Revenue recognized related to contract liabilities existing at January 1, 2021 was $109 million for the six months ended June 30, 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 June 30, 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 | $ | 162 |
2022 | 124 |
Thereafter | 139 |
Total | $ | 425 |

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 $122 million at June 30, 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 $50 million for the three and six months ended June 30, 2021, respectively, and $26 million and $53 million for the three and six months ended June 30, 2020, respectively, and was included in Selling, general and administrative expenses.

Note 3 Fair Value Measurements
As of June 30, 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 |  | June 30, 2021 |  | December 31, 2020
|  | Book Value |  | Fair Value |  | Book Value |  | Fair Value
(Dollars in millions) |  |  |  |  |  |  |  |  |

Other | 2 |  | 397 |  |  | 397 |  |  | 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 UScellular Senior Notes, which are traded on the New York Stock Exchange. 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 1.26% to 4.34% and 1.35% to 3.75% at June 30, 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.

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:

| June 30, 2021 |  | December 31, 2020

Note 5 Income Taxes
The effective tax rate on Income before income taxes for the three and six months ended June 30, 2021 was (42.0)% and 14.5%, respectively. These effective tax rates were lower than normal due primarily to the reduction of tax accruals resulting from expirations of state statute of limitations for prior tax years.
The effective tax rate on Income before income taxes for the three and six months ended June 30, 2020 was 5.5% and 5.2%, respectively. These effective tax rates were lower than normal due primarily to the income tax benefits of the CARES Act.
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 June 30, |  | Six Months Ended June 30,
| 2021 |  | 2020 |  | 2021 |  | 2020
(Dollars and shares in millions, except per share amounts) |  |  |  |  |  |  |
Net income attributable to UScellular shareholders | $ | 35 |  |  | $ | 68 |  |  | $ | 95 |  |  | $ | 139 |
Weighted average number of shares used in basic earnings per share | 87 |  |  | 86 |  |  | 87 |  |  | 86 |
Effects of dilutive securities | 1 |  |  | 1 |  |  | 1 |  |  | 1 |
Weighted average number of shares used in diluted earnings per share | 88 |  |  | 87 |  |  | 88 |  |  | 87 |
Basic earnings per share attributable to UScellular shareholders | $ | 0.40 |  |  | $ | 0.79 |  |  | $ | 1.10 |  |  | $ | 1.62 |
Diluted earnings per share attributable to UScellular shareholders | $ | 0.39 |  |  | $ | 0.78 |  |  | $ | 1.08 |  |  | $ | 1.59 |

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 and six months ended June 30, 2021, respectively, and 1 million for both the three and six months ended June 30, 2020.

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. The wireless spectrum licenses from Auction 107 were granted by the FCC in July 2021. Additionally, UScellular expects to be obligated to pay approximately $178 million in total from 2021 through 2024 related to relocation costs and accelerated relocation incentive payments. Such additional costs were accrued and capitalized at the time the licenses were granted, which occurred after the period ended June 30, 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.

The notes are expected to be redeemed on September 1, 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.

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 June 30, 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 $50 million and $88 million, during the six months ended June 30, 2021 and 2020, respectively, of which $21 million in 2021 and $67 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.

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 June 30, 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 June 30, 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 second quarter of 2021.
The maximum number of shares that may yet be purchased under this program was 4,452,000 as of June 30, 2021. There were no purchases made by or on behalf of UScellular, and no 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.
Other Information
In July 2021, UScellular amended and restated its term loan agreement to allow for an additional $200 million of borrowing capacity. Principal reductions on the existing borrowings are due and payable in quarterly installments of $0.75 million beginning in December 2021. Amounts borrowed under the existing term loan agreement will bear interest at a rate of LIBOR plus 2.0% and be due and payable in July 2028. Borrowings under the additional $200 million borrowing capacity will bear interest at a rate of LIBOR plus 2.50% and be due and payable in July 2031. Principal reductions on any new borrowings will be due and payable in quarterly installments beginning in December 2022 at a rate of 0.25% of the initial outstanding principal balance through September 2026 and at a rate of 0.625% of the initial outstanding principal balance from December 2026 through the maturity date. Additionally, the consolidated leverage ratio, as defined in the agreement, may not be greater than 3.75 to 1.00 as of the end of any fiscal quarter. There were no significant changes to other terms of the term loan agreement.
