Special Note Regarding Forward-Looking Statements
This report and other documents filed by us under the federal securities law include, and future oral or written statements or press releases by us and our management may include, forward-looking statements about our business, financial condition, operating results or prospects. These "forward-looking" statements are defined by, and are subject to the "safe harbor" protections under, the federal securities laws. These statements include, among others:
•statements regarding how the health and economic challenges raised by the COVID-19 pandemic may impact our business, operations, cash flows or financial position;
•forecasts of our anticipated future results of operations, cash flows or financial position;
•statements concerning the anticipated impact of our transactions, investments, product development, participation in government programs, and other initiatives, including synergies or costs associated with these initiatives;
•statements about our liquidity, profitability, profit margins, tax position, tax assets, tax rates, asset values, contingent liabilities, growth opportunities, growth rates, acquisition and divestiture opportunities, business prospects, regulatory and competitive outlook, market share, product capabilities, investment and expenditure plans, business strategies, dividend and securities repurchase plans, leverage, capital allocation plans, financing alternatives and sources, and pricing plans; and
•other similar statements of our expectations, beliefs, future plans and strategies, anticipated developments and other matters that are not historical facts, many of which are highlighted by words such as “may,” “will,” “would,” “could,” “should,” “plan,” “believes,” “expects,” “anticipates,” “estimates,” “projects,” “intends,” “likely,” “seeks,” “hopes,” or variations or similar expressions with respect to the future.
These forward-looking statements are based upon our judgment and assumptions as of the date such statements are made concerning future developments and events, many of which are beyond our control. These forward-looking statements, and the assumptions upon which they are based, (i) are not guarantees of future results, (ii) are inherently speculative and (iii) are subject to a number of risks and uncertainties. Actual events and results may differ materially from those anticipated, estimated, projected or implied by us in those statements if one or more of these risks or uncertainties materialize, or if our underlying assumptions prove incorrect. All of our forward-looking statements are qualified in their entirety by reference to our discussion of factors that could cause our actual results to differ materially from those anticipated, estimated, projected or implied by us in those forward-looking statements. Factors that could affect actual results include but are not limited to:
•uncertainties regarding the impact that COVID-19 health and economic disruptions will continue to have on our business, operations, cash flows and corporate initiatives;
•the effects of competition from a wide variety of competitive providers, including decreased demand for our more mature service offerings and increased pricing pressures;
•the effects of new, emerging or competing technologies, including those that could make our products less desirable or obsolete;
•our ability to attain our key operating imperatives, including simplifying and consolidating our network, simplifying and automating our service support systems, strengthening our relationships with customers and attaining projected cost savings;

•our ability to generate cash flows sufficient to fund our financial commitments and objectives, including our capital expenditures, operating costs, debt repayments, dividends, pension contributions and other benefits payments;
•our ability to successfully and timely implement our operating plans and corporate strategies, including our deleveraging strategy;
•changes in our operating plans, corporate strategies, dividend payment plans or other capital allocation plans, whether based upon COVID-19 disruptions, changes in our cash flows, cash requirements, financial performance, financial position, market conditions or otherwise;
•the impact of any future material acquisitions or divestitures that we may engage in;
•the negative impact of increases in the costs of our pension, health, post-employment or other benefits, including those caused by changes in markets, interest rates, mortality rates, demographics or regulations;
•the potential negative impact of customer complaints, government investigations, security breaches or service outages impacting us or our industry;
•adverse changes in our access to credit markets on favorable terms, whether caused by changes in our financial position, lower credit ratings, unstable markets or otherwise;

•the effects of changes in accounting policies, practices or assumptions, including changes that could potentially require additional future impairment charges;
•the effects of adverse weather, terrorism, epidemics, pandemics, rioting, societal unrest, or other natural or man-made disasters or disturbances;
•the potential adverse effects if our internal controls over financial reporting have weaknesses or deficiencies, or otherwise fail to operate as intended;
•the effects of more general factors such as changes in interest rates, in exchange rates, in operating costs, in public policy, in the views of financial analysts, or in general market, labor, economic or geo-political conditions; and
•other risks referenced in the "Risk Factors" section or other portions of this report or other of our filings with the U.S. Securities and Exchange Commission (the "SEC").
Additional factors or risks that we currently deem immaterial, that are not presently known to us or that arise in the future could also cause our actual results to differ materially from our expected results. Given these uncertainties, investors are cautioned not to unduly rely upon our forward-looking statements, which speak only as of the date made. We undertake no obligation to publicly update or revise any forward-looking statements for any reason, whether as a result of new information, future events or developments, changed circumstances, or otherwise. Furthermore, any information about our intentions contained in any of our forward-looking statements reflects our intentions as of the date of such forward-looking statement, and is based upon, among other things, existing regulatory, technological, industry, competitive, economic and market conditions, and our assumptions as of such date. We may change our intentions, strategies or plans (including our dividend or other capital allocation plans) at any time and without notice, based upon any changes in such factors, in our assumptions or otherwise.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
References in the Notes to "Lumen Technologies, Inc.," "Lumen Technologies" or "Lumen," "we," "us," the "Company," and "our" refer to Lumen Technologies and its consolidated subsidiaries, unless the context otherwise requires. References in the Notes to "Level 3" refer to Level 3 Parent, LLC and its predecessor, Level 3 Communications, Inc., which we acquired on November 1, 2017.
(1) Background
General
We are an international facilities-based technology and communications company engaged primarily in providing a broad array of integrated services to our business and mass markets customers. Our specific products and services are detailed in Note 3—Revenue Recognition.
Basis of Presentation
Our consolidated balance sheet as of December 31, 2020, which was derived from our audited consolidated financial statements, and our unaudited interim consolidated financial statements provided herein have been prepared in accordance with the instructions for Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to rules and regulations of the SEC. However, in our opinion, the disclosures made therein are adequate to make the information presented not misleading. We believe that these consolidated financial statements include all normal recurring adjustments necessary to fairly present the results for the interim periods. The consolidated results of operations and cash flows for the first three months of the year are not necessarily indicative of the consolidated results of operations and cash flows that might be expected for the entire year. These consolidated financial statements and the accompanying notes should be read in conjunction with the audited consolidated financial statements and the notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2020.
The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries in which we have a controlling interest. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated.
To simplify the overall presentation of our consolidated financial statements, we report immaterial amounts attributable to noncontrolling interests in certain of our subsidiaries as follows: (i) income attributable to noncontrolling interests in other income (expense), net, (ii) equity attributable to noncontrolling interests in additional paid-in capital and (iii) cash flows attributable to noncontrolling interests in other, net, financing activities.
We reclassified certain prior period amounts to conform to the current period presentation, including the categorization of our revenue and expenses in our segment reporting. See Note 11—Segment Information for additional information. These changes had no impact on total operating revenue, total operating expenses or net income (loss) for any period.
Operating lease assets are included in other, net under goodwill and other assets on our consolidated balance sheets. Noncurrent operating lease liabilities are included in other under deferred credits and other liabilities on our consolidated balance sheets.
There were no book overdrafts included in accounts payable at March 31, 2021 or December 31, 2020.

Summary of Significant Accounting Policies
The significant accounting policy below is in addition to the significant accounting policies described in Note 1— Background and Summary of Significant Accounting Policies to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020.
Operating Lease Income
Lumen Technologies leases various dark fiber, office facilities, colocation facilities, switching facilities, other network sites and service equipment to third parties under operating leases. Lease and sublease income are included in operating revenue in our consolidated statements of operations.
For the three months ended March 31, 2021 and 2020, our gross rental income was $332 million and $333 million, respectively, which represents approximately 7% and 6%, respectively, of our operating revenue for the three months ended March 31, 2021 and 2020.
Recently Adopted Accounting Pronouncements
Debt
On January 1, 2021, we adopted ASU 2020-09, "Debt (Topic 470) Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762" ("ASU 2020-09"). This ASU amends and supersedes various SEC paragraphs to reflect SEC Release No. 33-10762, which includes amendments to the financial disclosure requirements applicable to registered debt offerings that include credit enhancements, such as subsidiary guarantees. The adoption of ASU 2020-09 did not have a material impact to our consolidated financial statements.
Investments
On January 1, 2021, we adopted ASU 2020-01, "Investments - Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) - Clarifying the Interactions between Topic 321, Topic 323, and Topic 815)" ("ASU 2020-01"). This ASU, among other things, clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, Investments - Equity Method and Joint Ventures, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. As of March 31, 2021, we determined there was no application or discontinuation of the equity method during the reporting periods. The adoption of ASU 2020-01 did not have a material impact to our consolidated financial statements.
Income taxes
On January 1, 2021, we adopted ASU 2019-12, "Simplifying the Accounting for Income Taxes (Topic 740)" ("ASU 2019-12"). This ASU removes certain exceptions for investments, intra-period allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. The adoption of ASU 2019-12 did not have a material impact to our consolidated financial statements.
Measurement of Credit Losses on Financial Instruments
We adopted ASU 2016-13, "Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13") on January 1, 2020 and recognized a cumulative adjustment to our accumulated deficit as of the date of adoption of $9 million, net of tax effect of $2 million. Please refer to Note 4—Credit Losses on Financial Instruments for more information.

Recently Issued Accounting Pronouncements
In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848)" Scope" ("ASU 2021-01"), which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in Topic 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. ASU 2021-01 provides option guidance for a limited time to ease the potential burden in accounting for reference rate reform. As of March 31, 2021, we are currently evaluating our contracts and the optional expedients provided by the new standard.
In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU 2020-04"), designed to ease the burden of accounting for contract modifications related to the global market-wide reference rate transition period. Subject to certain criteria, ASU 2020-04 provides qualifying entities the option to apply expedients and exceptions to contract modifications and hedging accounting relationships made until December 31, 2022. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. ASU 2020-04 provides optional guidance for a limited time to ease the potential burden in accounting for reference rate reform. As of March 31, 2021, we are evaluating the existing contracts and the impact on consolidated financial statements.
(2) Goodwill, Customer Relationships and Other Intangible Assets
Goodwill, customer relationships and other intangible assets consisted of the following:

| March 31, 2021 |  | December 31, 2020
| (Dollars in millions)
Goodwill | $ | 18,854 |  |  | 18,870 |
Indefinite-life intangible assets | $ | 9 |  |  | 278 |
Other intangible assets subject to amortization: |  |  |
Customer relationships, less accumulated amortization of $11,356 and $11,060 | 6,035 |  |  | 6,344 |
Capitalized software, less accumulated amortization of $3,366 and $3,279 | 1,509 |  |  | 1,520 |
Trade names, patents and other, less accumulated amortization of $134 and $120 | 331 |  |  | 77 |
Total other intangible assets, net | $ | 7,884 |  |  | 8,219 |

When we acquired Embarq Corporation in 2009, we acquired certain right-of-way assets and, because there were no legal, regulatory, contractual or other factors that would reasonably limit the useful life of these assets, we classified them as indefinite-lived and, as such, these assets were not amortized. However, as we leverage our fiber infrastructure assets, our reliance on the legacy infrastructure (largely copper-based) acquired from Embarq is diminishing. Our recent digital transformation efforts have prompted management to reassess and ultimately change the accounting treatment of these indefinite-lived assets to align with our focus on growth products versus our declining products. As a result, during the first quarter of 2021, we reclassified an indefinite-lived intangible asset to definite-lived intangible asset. As of January 1, 2021 we began amortizing the $268 million asset over its estimated 9-year remaining life. This change in the estimated remaining economic life resulted in an increase in amortization expense of approximately $7 million for the three months ended March 31, 2021 and is expected to increase amortization expense by approximately $30 million for the year ending December 31, 2021. The increase in amortization expense, net of tax, reduced consolidated net income by approximately $5 million, with no impact per basic and diluted common share, for the three months ended March 31, 2021 and is expected to reduce consolidated net income by approximately $23 million, or $0.02 per basic and diluted common share, for the year ending December 31, 2021.
Our goodwill was derived from numerous acquisitions where the purchase price exceeded the fair value of the net assets acquired.
13

Table of Contents
We assess our goodwill and other indefinite-lived intangible assets for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. We are required to write down the value of goodwill only when our assessment determines the carrying value of equity of any of our reporting units exceeds its fair value. Our annual impairment assessment date for goodwill is October 31, at which date we assess our reporting units. Our annual impairment assessment date for indefinite-lived intangible assets other than goodwill is December 31.
Our reporting units are not discrete legal entities with discrete full financial statements. Our assets and liabilities are employed in and relate to the operations of multiple reporting units. For each reporting unit, we compare its estimated fair value of equity to its carrying value of equity that we assign to the reporting unit. If the estimated fair value of the reporting unit is greater than the carrying value, we conclude that no impairment exists. If the estimated fair value of the reporting unit is less than the carrying value, we record an impairment equal to the excess amount. Depending on the facts and circumstances, we typically estimate the fair value of our reporting units by considering either or both of (i) a discounted cash flow method, which is based on the present value of projected cash flows over a discrete projection period and a terminal value, which represents the value of expected normalized cash flows of the reporting units following the discrete projection period, and (ii) a market approach, which includes the use of market multiples of publicly-traded companies whose services are comparable to ours.
As previously announced, we completed an internal reorganization in January 2021. We now, as a result, report two segments: Business and Mass Markets. The following table shows the rollforward of goodwill assigned to our reportable segments, including the reorganization, from December 31, 2020 through March 31, 2021:

| International and Global Accounts | Enterprise | Small and Medium Business | Wholesale | Consumer | Business | Mass Markets | Total
| (Dollars in millions)
As of December 31, 2020(1) | $ | 2,555 |  | 4,738 |  | 2,808 |  | 3,114 |  | 5,655 |  | — |  | — |  | 18,870 |
January 2021 reorganization | (2,555) |  | (4,738) |  | (2,808) |  | (3,114) |  | (5,655) |  | 12,173 |  | 6,697 |  | — |
Effect of foreign currency exchange rate change and other | — |  | — |  | — |  | — |  | — |  | (16) |  | — |  | (16) |
As of March 31, 2021(1) | $ | — |  | — |  | — |  | — |  | — |  | 12,157 |  | 6,697 |  | 18,854 |

______________________________________________________________________
(1)Goodwill at March 31, 2021 and December 31, 2020 is net of accumulated impairment losses of $12.9 billion.
The January 2021 reorganization was considered a change in event or circumstance which required an assessment of our goodwill for impairment. We performed a qualitative impairment assessment and concluded it is more likely than not that the fair value of each of our reporting units exceeded the carrying value of equity of our reporting units at January 31, 2021. Therefore, no impairment existed as of our assessment date.
Total amortization expense for intangible assets for the three months ended March 31, 2021 and 2020 totaled $425 million and $431 million, respectively. As of March 31, 2021, the gross carrying amount of goodwill, customer relationships, indefinite-life and other intangible assets was $41.6 billion.

Table of Contents
We estimate that total amortization expense for intangible assets for the years ending December 31, 2021 through 2025 will be as follows:

| (Dollars in millions)
2021 (remaining nine months) | $ | 893 |
2022 | 1,081 |

2024 | 887 |
2025 | 797 |

Customer Receivables and Contract Balances
The following table provides balances of customer receivables, contract assets and contract liabilities as of March 31, 2021 and December 31, 2020:

| March 31, 2021 |  | December 31, 2020
| (Dollars in millions)
Customer receivables(1) | $ | 1,805 |  |  | 1,889 |
Contract assets | 103 |  |  | 108 |
Contract liabilities | 883 |  |  | 950 |

______________________________________________________________________
(1)Reflects gross customer receivables of $2.0 billion and $2.1 billion, net of allowance for credit losses of $148 million and $174 million, at March 31, 2021 and December 31, 2020, respectively.
Contract liabilities are consideration we have received from our customers or billed in advance of providing goods or services promised in the future. We defer recognizing this consideration as revenue until we have satisfied the related performance obligation to the customer. Contract liabilities include recurring services billed one month in advance and installation and maintenance charges that are deferred and recognized over the actual or expected contract term, which typically ranges from one to five years depending on the service. Contract liabilities are included within deferred revenue in our consolidated balance sheets. During the three months ended March 31, 2021, we recognized $425 million of revenue that was included in contract liabilities as of January 1, 2021. During the three months ended March 31, 2020, we recognized $495 million of revenue that was included in contract liabilities as of January 1, 2020.
Performance Obligations
As of March 31, 2021, our estimated revenue expected to be recognized in the future related to performance obligations associated with existing customer contracts that are partially or wholly unsatisfied is approximately $5.2 billion. We expect to recognize approximately 90% of this revenue through 2023, with the balance recognized thereafter.
These amounts exclude (i) the value of unsatisfied performance obligations for contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed (for example, uncommitted usage or non-recurring charges associated with professional or technical services to be completed), and (ii) contracts that are classified as leasing arrangements that are not subject to ASC 606.

Contract Costs
The following table provides changes in our contract acquisition costs and fulfillment costs:

| Three Months Ended March 31, 2021
| Acquisition Costs |  | Fulfillment Costs
| (Dollars in millions)
Beginning of period balance | $ | 289 |  |  | 216 |
Costs incurred | 44 |  |  | 37 |
Amortization | (54) |  |  | (37) |
End of period balance | $ | 279 |  |  | 216 |

| Three Months Ended March 31, 2020
| Acquisition Costs |  | Fulfillment Costs
| (Dollars in millions)
Beginning of period balance | $ | 326 |  |  | 221 |
Costs incurred | 49 |  |  | 36 |
Amortization | (55) |  |  | (37) |
End of period balance | $ | 320 |  |  | 220 |

Acquisition costs include commission fees paid to employees as a result of obtaining contracts. Fulfillment costs include third party and internal costs associated with the provision, installation and activation of telecommunications services to customers, including labor and materials consumed for these activities.
Deferred acquisition and fulfillment costs are amortized based on the transfer of services on a straight-line basis over the average customer life of approximately 30 months for mass markets and business customers. Amortized fulfillment costs are included in cost of services and products and amortized acquisition costs are included in selling, general and administrative expenses in our consolidated statements of operations. The amount of these deferred costs that are anticipated to be amortized in the next 12 months are included in other current assets on our consolidated balance sheets. The amount of deferred costs expected to be amortized beyond the next 12 months is included in other non-current assets on our consolidated balance sheets. Deferred acquisition and fulfillment costs are assessed for impairment on an annual basis.
(4) Credit Losses on Financial Instruments
In accordance with ASC 326, "Financial Instruments - Credit Losses," we aggregate financial assets with similar risk characteristics to align our expected credit losses with the credit quality or deterioration over the life of such assets. We monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change each reporting period. Financial assets that do not share risk characteristics with other financial assets are evaluated separately. Our financial assets measured at amortized cost primarily consist of accounts receivable.
We implemented the new standard effective January 1, 2020, using a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our use of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable.
18

Table of Contents
In conjunction with our internal reorganization, as referenced in Note 11—Segment Information, we pooled certain assets with similar credit risk characteristics based on the nature of our customers, their industry, policies used to grant credit terms and their historical and expected credit loss patterns. Additionally, we reassessed our historical loss period for the segment portfolio reorganization.
If there is a deterioration of a customer's financial condition or if future default rates in general differ from currently anticipated default rates (including changes caused by COVID-19), we may need to adjust the allowance for credit losses, which would affect earnings in the period that adjustments are made.
The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future.
The following table presents the activity of our allowance for credit losses by accounts receivable portfolio:

| Business |  | Mass Markets |  | Total |  |  |  |
| (Dollars in millions) |  |  |  |
Beginning balance at January 1, 2021(1) | $ | 109 |  |  | 82 |  |  | 191 |  |  |  |  |
Provision for expected losses | 13 |  |  | 14 |  |  | 27 |  |  |  |  |
Write-offs charged against the allowance | (19) |  |  | (48) |  |  | (67) |  |  |  |  |
Recoveries collected | 5 |  |  | 6 |  |  | 11 |  |  |  |  |
Ending balance at March 31, 2021 | $ | 108 |  |  | 54 |  |  | 162 |  |  |  |  |

______________________________________________________________________
(1)As described in Note 11—Segment Information, we completed an internal reorganization in January 2021. As a result of this change, allowance for credit losses previously included in the Consumer and Business portfolio of $70 million related to consumer and $12 million related to our small business group, respectively, were reclassified to the Mass Markets allowance for credit losses on January 1, 2021.
For the three months ended March 31, 2021, we decreased our allowance for credit losses for our business and mass markets accounts receivable portfolios primarily due to higher write-off activity in the quarter with the easing of prior delays due to COVID-19 related restrictions in 2020.

Total long-term debt | $ | 31,769 |

Repayments
During the three months ended March 31, 2021, Lumen Technologies and its affiliates repaid or redeemed approximately $1.3 billion of their respective debt obligations, which primarily included $150 million of payments on our revolving credit facility, $900 million redemption of Level 3 Financing, Inc. senior notes and $235 million redemption of Qwest Corporation senior notes. These redemptions resulted in a net gain of $8 million.
New Issuances
On January 13, 2021, Level 3 Financing, Inc. issued $900 million aggregate principal amount of 3.750% Sustainability-Linked Senior Notes due 2029 (the "Sustainability-Linked Notes"). The net proceeds were used, together with cash on hand, to redeem certain of its outstanding senior note indebtedness. See "—Repayments" above. The Sustainability-Linked Notes are (i) guaranteed by Level 3 Parent, LLC and (ii) expected to be guaranteed by Level 3 Communications, LLC, upon the receipt of all requisite material governmental authorizations.
Covenants
Certain of our debt instruments contain affirmative and negative covenants. Debt at Lumen Technologies, Inc. and Level 3 Financing, Inc. contain more extensive covenants including, among other things and subject to certain exceptions, restrictions on their ability to declare or pay dividends, repay certain other indebtedness, create liens, incur additional indebtedness, make investments, engage in transactions with their affiliates, dispose of assets and merge or consolidate with any other person. Also, Lumen Technologies, Inc. and certain of its affiliates will be required to offer to purchase certain of their respective outstanding debt under certain circumstances in connection with certain specified "change of control" transactions.
Certain of our debt instruments contain cross-payment default or cross-acceleration provisions.
Compliance
As of March 31, 2021, Lumen Technologies, Inc. believes it and its subsidiaries were in compliance with the provisions and financial covenants in their respective material debt agreements in all material respects.
(6) Severance
Periodically, we reduce our workforce and accrue liabilities for the related severance costs. These workforce reductions result primarily from the progression or completion of our post-acquisition integration plans, increased competitive pressures, cost reduction initiatives, process improvements through automation and reduced workload demands due to the loss of customers purchasing certain services.

Table of Contents
Benefits paid by the Combined Pension Plan are paid through a trust that holds all of the Plan's assets. Based on current laws and circumstances, we do not expect any contributions to be required for the Combined Pension Plan during 2021. The amount of required contributions to the Combined Pension Plan in 2022 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. We occasionally make voluntary contributions in addition to required contributions. Based on current laws and circumstances, we do not believe we are required to make any contributions to the Combined Pension Plan in 2021, but we could make voluntary contributions to the trust for the Combined Pension Plan in 2021.
(8) Earnings Per Common Share
Basic and diluted earnings per common share were calculated as follows:

| Three Months Ended March 31,
| 2021 |  | 2020
| (Dollars in millions, except per share amounts, shares in thousands)
Income (Numerator): |  |  |
Net income | $ | 475 |  |  | 314 |
Net income applicable to common stock for computing basic earnings per common share | 475 |  |  | 314 |
Net income as adjusted for purposes of computing diluted earnings per common share | $ | 475 |  |  | 314 |
Shares (Denominator): |  |  |
Weighted-average number of shares: |  |  |
Outstanding during period | 1,100,350 |  |  | 1,092,970 |
Non-vested restricted stock | (17,876) |  |  | (17,511) |
Weighted-average shares outstanding for computing basic earnings per common share | 1,082,474 |  |  | 1,075,459 |
Incremental common shares attributable to dilutive securities: |  |  |
Shares issuable under convertible securities | 10 |  |  | 10 |
Shares issuable under incentive compensation plans | 9,102 |  |  | 6,285 |
Number of shares as adjusted for purposes of computing diluted earnings per common share | 1,091,586 |  |  | 1,081,754 |
Basic earnings per common share | $ | 0.44 |  |  | 0.29 |
Diluted earnings per common share | $ | 0.44 |  |  | 0.29 |

Our calculation of diluted earnings per common share excludes shares of common stock that are issuable upon exercise of stock options when the exercise price is greater than the average market price of our common stock. We also exclude unvested restricted stock awards that are antidilutive as a result of unrecognized compensation cost. Such shares were less than 1 million for the three months ended March 31, 2021 and 2.7 million for the three months ended March 31, 2020.
(9) Fair Value of Financial Instruments
Our financial instruments consist of cash, cash equivalents and restricted cash, accounts receivable, accounts payable, long-term debt, excluding finance lease and other obligations, and interest rate swap contracts. Due to their short-term nature, the carrying amounts of our cash, cash equivalents and restricted cash, accounts receivable and accounts payable approximate their fair values.

Table of Contents
The three input levels in the hierarchy of fair value measurements defined by the FASB generally as follows:

Input Level |  | Description of Input
Level 1 |  | Observable inputs such as quoted market prices in active markets.
Level 2 |  | Inputs other than quoted prices in active markets that are either directly or indirectly observable.
Level 3 |  | Unobservable inputs in which little or no market data exists.

The following table presents the carrying amounts and estimated fair values of our financial liabilities as of March 31, 2021 and December 31, 2020:

|  |  | March 31, 2021 |  | December 31, 2020
| Input Level |  | Carrying Amount |  | Fair Value |  | Carrying Amount |  | Fair Value

Interest rate swap contracts (see Note 10) | 2 |  | $ | 87 |  |  | 87 |  |  | 107 |  |  | 107 |

(10) Derivative Financial Instruments
From time to time, we use derivative financial instruments, primarily interest rate swaps, to manage our exposure to fluctuations in interest rates. Our primary objective in managing interest rate risk is to decrease the volatility of our earnings and cash flows affected by changes in the underlying rates. We have floating rate long-term debt (see Note 5—Long-Term Debt and Credit Facilities of this report). These obligations expose us to variability in interest payments due to changes in interest rates. If interest rates increase, interest expense increases. Conversely, if interest rates decrease, interest expense also decreases. We have designated our currently outstanding interest rate swap agreements as cash flow hedges. As described further below, under these hedges, we receive variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the lives of the agreements without exchange of the underlying notional amount. The change in the fair value of the interest rate swap agreements is reflected in accumulated other comprehensive income ("AOCI") and, as described below, is subsequently reclassified into earnings in the period that the hedged transaction affects earnings by virtue of qualifying as effective cash flow hedges. We do not use derivative financial instruments for speculative purposes.
As of March 31, 2021 and December 31, 2020, we evaluated the effectiveness of our hedges quantitatively and any hedges we had entered into at the time qualified as effective hedge relationships.
We may be exposed to credit-related losses in the event of non-performance by counterparties. The counterparties to any of the financial derivatives we enter into are major institutions with investment grade credit ratings. We evaluate counterparty credit risk before entering into any hedge transaction and continue to closely monitor the financial market and the risk that our counterparties will default on their obligations as part of our quarterly qualitative effectiveness evaluation.
Amounts accumulated in AOCI related to derivatives are indirectly recognized in earnings as periodic settlement payments are made throughout the term of the swaps.

Table of Contents
The table below presents the fair value of our derivative financial instruments as well as their classification on the consolidated balance sheet at March 31, 2021 and December 31, 2020, as follows (in millions):

|  |  | March 31, 2021 |  | December 31, 2020
Derivatives designated as | Balance Sheet Location |  | Fair Value
Cash flow hedging contracts | Other current and noncurrent liabilities |  | $ | 87 |  |  | 107 |

The amount of unrealized (gains) losses recognized in AOCI consists of the following (in millions):

Derivatives designated as hedging instruments |  | 2021 |  | 2020
Cash flow hedging contracts |  |  |  |
Three Months Ended March 31, |  | $ | — |  |  | 106 |

The amount of realized losses reclassified from AOCI to the statement of operations consists of the following
(in millions):

Derivatives designated as hedging instruments |  | 2021 |  | 2020
Cash flow hedging contracts |  |  |  |
Three Months Ended March 31, |  | $ | 20 |  |  | 5 |

Amounts currently included in AOCI will be reclassified into earnings prior to the ongoing settlements of these cash flow hedging contracts until 2022. We estimate that $81 million of net losses on the interest rate swaps (based on the estimated LIBOR curve as of March 31, 2021) will be reflected in our statements of operations within the next 12 months.
(11) Segment Information
Jeff Storey, our chief operating decision maker ("CODM"), made changes to our segment and customer-facing sales channel reporting categories beginning in 2021 to align with operational changes designed to better support our customers. Following these changes, we now report two segments: Business and Mass Markets. The Business segment includes four sales channels: International and Global Accounts, Large Enterprise, Mid-Market Enterprise and Wholesale. These changes also include both the creation of new product categories and the realignment of products and services within previously reported product categories to better reflect product life cycles and our go-to-market approach. For Business segment revenue, we report the following product categories: Compute and Application Services, IP and Data Services, Fiber Infrastructure Services and Voice and Other, by the sales channels outlined above. For Mass Markets segment revenue, we report the following product categories: Consumer Broadband, SBG Broadband, Voice and Other and CAF II. See detailed descriptions of these product and service categories in Note 3—Revenue Recognition.
As described in more detail below, our segments are managed based on the direct costs of providing services to their customers and the associated selling, general and administrative costs (primarily salaries and commissions). Shared costs are managed separately and included in "Operations and Other" in the tables below. As referenced above, we reclassified certain prior period amounts to conform to the current period presentation. See Note 1— Background for additional detail on these changes.
At March 31, 2021, we had the following two reportable segments:
•Business Segment: Under our Business segment, we provide our products and services under four distinct sales channels to meet the needs of our enterprise and commercial customers; and
•Mass Markets Segment: Under our Mass Markets segment, we provide products and services to consumer and small business customers.

Revenue and Expenses
Our segment revenue includes all revenue from our two segments as described in more detail above. Our segment revenue is based upon each customer's classification. We report our segment revenue based upon all services provided to that segment's customers. Our segment expenses include specific cost of service expenses incurred as a direct result of providing services and products to segment customers, along with selling, general and administrative expenses that are directly associated with specific segment customers or activities.
The following items are excluded from our segment results, because they are centrally managed and not monitored by or reported to our CODM by segment:
•network expenses not incurred as a direct result of providing services and products to segment customers;
•centrally managed expenses such as Operations, Finance, Human Resources, Legal, Marketing, Product Management and IT, which are reported as "Operations and Other";
•depreciation and amortization expense or impairments;
•interest expense, because we manage our financing on a consolidated basis and have not allocated assets or debt to specific segments;
•stock-based compensation; and

(12) Commitments, Contingencies and Other Items
We are subject to various claims, legal proceedings and other contingent liabilities, including the matters described below, which individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows. As a matter of course, we are prepared to both litigate these matters to judgment as needed, as well as to evaluate and consider reasonable settlement opportunities.
Irrespective of its merits, litigation may be both lengthy and disruptive to our operations and could cause significant expenditure and diversion of management attention. We review our litigation accrual liabilities on a quarterly basis, but in accordance with applicable accounting guidelines only establish accrual liabilities when losses are deemed probable and reasonably estimable and only revise previously-established accrual liabilities when warranted by changes in circumstances, in each case based on then-available information. As such, as of any given date we could have exposure to losses under proceedings as to which no liability has been accrued or as to which the accrued liability is inadequate. Amounts accrued for our litigation and non-income tax contingencies at March 31, 2021 aggregated to approximately $119 million and are included in other current liabilities and other liabilities in our consolidated balance sheet as of such date. The establishment of an accrual does not mean that actual funds have been set aside to satisfy a given contingency. Thus, the resolution of a particular contingency for the amount accrued could have no effect on our results of operations but nonetheless could have an adverse effect on our cash flows.
In this Note, when we refer to a class action as "putative" it is because a class has been alleged, but not certified, in that matter.
Principal Proceedings
Shareholder Class Action Suit
Lumen and certain Lumen Board of Directors members and officers were named as defendants in a putative shareholder class action lawsuit filed on June 12, 2018 in the Boulder County District Court of the state of Colorado, captioned Houser et al. v. CenturyLink, et al. The complaint asserts claims on behalf of a putative class of former Level 3 shareholders who became CenturyLink, Inc. shareholders as a result of our acquisition of Level 3. It alleges that the proxy statement provided to the Level 3 shareholders failed to disclose various material information of several kinds, including information about strategic revenue, customer loss rates, and customer account issues, among other items. The complaint seeks damages, costs and fees, rescission, rescissory damages, and other equitable relief. In May 2020, the court dismissed the complaint. Plaintiffs appealed that decision, and the appeal is pending.

State Tax Suits
Since 2012, a number of Missouri municipalities have asserted claims in the Circuit Court of St. Louis County, Missouri, alleging that we and several of our subsidiaries have underpaid taxes. These municipalities are seeking, among other things, declaratory relief regarding the application of business license and gross receipts taxes and back taxes from 2007 to the present, plus penalties and interest. In a February 2017 ruling in connection with one of these pending cases, the court entered an order awarding plaintiffs $4 million and broadening the tax base on a going-forward basis. We appealed that decision to the Missouri Supreme Court. In December 2019, it affirmed the circuit court's order in some respects and reversed it in others, remanding the case to the circuit court for further proceedings. The Missouri Supreme Court's decision reduced our exposure in the case. In a June 2017 ruling in connection with another one of these pending cases, the circuit court made findings in a non-final ruling which, if not overturned or modified in light of the Missouri Supreme Court's decision, will result in a tax liability to us well in excess of the contingent liability we have established. The circuit court has indicated it does not intend to alter its 2017 ruling when it issues its final decision. Once a final decision is issued, we will have the right to pursue an appeal. We continue to vigorously defend against these claims.
Billing Practices Suits
In June 2017, a former employee filed an employment lawsuit against us claiming that she was wrongfully terminated for alleging that we charged some of our retail customers for products and services they did not authorize. Thereafter, based in part on the allegations made by the former employee, several legal proceedings were filed, including consumer class actions in federal and state courts, a series of securities investor class actions in federal courts and several shareholder derivative actions in federal and Louisiana state courts. The derivative cases were brought on behalf of CenturyLink, Inc. against certain current and former officers and directors of the Company and seek damages for alleged breaches of fiduciary duties.
The consumer class actions, the securities investor class actions, and the federal derivative actions were transferred to the U.S. District Court for the District of Minnesota for coordinated and consolidated pretrial proceedings as In Re: CenturyLink Sales Practices and Securities Litigation. We have settled the consumer and securities investor class actions. The consumer class settlement was approved by the Court and is final. Approximately 12,000 potential class members elected to opt out of the consumer class settlement, and we have settled the claims of approximately 11,000 such class members asserted by one law firm subject to certain conditions. The securities investors class settlement entails a payment of $55 million, which we expect to be paid by our insurers. That settlement has received preliminary court approval and is subject to certain conditions including final approval by the Court. The derivative actions remain pending.
We have engaged in discussions regarding related claims with a number of state attorneys general, and have entered into agreements settling certain of the consumer practices claims asserted by state attorneys general. While we do not agree with allegations raised in these matters, we have been willing to consider reasonable settlements where appropriate.
Peruvian Tax Litigation
In 2005, the Peruvian tax authorities ("SUNAT") issued tax assessments against one of our Peruvian subsidiaries asserting $26 million, of additional income tax withholding and value-added taxes ("VAT"), penalties and interest for calendar years 2001 and 2002 on the basis that the Peruvian subsidiary incorrectly documented its importations. After taking into account the developments described below, as well as the accrued interest and foreign exchange effects, we believe the total amount of our exposure is $1 million at March 31, 2021.
We challenged the assessments via administrative and then judicial review processes. In October 2011, the highest administrative review tribunal (the Tribunal) decided the central issue underlying the 2002 assessments in SUNAT's favor. We appealed the Tribunal's decision to the first judicial level, which decided the central issue in favor of Level 3. SUNAT and we filed cross-appeals with the court of appeal. In May 2017, the court of appeal issued a decision reversing the first judicial level. In June 2017, we filed an appeal of the decision to the Supreme Court of Justice, the final judicial level. Oral argument was held before the Supreme Court of Justice in October 2018. A decision on this case is pending.

Table of Contents
In October 2013, the Tribunal decided the central issue underlying the 2001 assessments in SUNAT’s favor. We appealed that decision to the first judicial level in Peru, which decided the central issue in favor of SUNAT. In June 2017, we filed an appeal with the court of appeal. In November 2017, the court of appeals issued a decision affirming the first judicial level and we filed an appeal of the decision to the Supreme Court of Justice. Oral argument was held before the Supreme Court of Justice in June 2019. A decision on this case is pending.
Brazilian Tax Claims
The São Paulo and Rio de Janeiro state tax authorities have issued tax assessments against our Brazilian subsidiaries for the Tax on Distribution of Goods and Services (“ICMS”), mainly with respect to revenue from leasing certain assets and revenue from the provision of Internet access services by treating such activities as the provision of communications services, to which the ICMS tax applies. We filed objections to these assessments in both states, arguing, among other things that neither the lease of assets nor the provision of Internet access qualifies as “communication services” subject to ICMS.
We have appealed to the respective state judicial courts the decisions by the respective state administrative courts that rejected our objections to these assessments. In cases in which state lower courts ruled partially in our favor finding that the lease assets are not subject to ICMS, the State appealed those rulings. In other cases, the assessment was affirmed at the first administrative level and we have appealed to the second administrative level. Other assessments are still pending state judicial decisions.
We are vigorously contesting all such assessments in both states and view the assessment of ICMS on revenue from equipment leasing and Internet access to be without merit. These assessments, if upheld, could result in a loss of $12 million to as high as $49 million as of March 31, 2021, in excess of the reserved accruals established for these matters.
Qui Tam Action
Level 3 was notified in late 2017 of a qui tam action pending against Level 3 Communications, Inc. and others in the U.S. District Court for the Eastern District of Virginia, captioned United States of America ex rel., Stephen Bishop v. Level 3 Communications, Inc. et al. The original qui tam complaint and an amended complaint were filed under seal on November 26, 2013 and June 16, 2014, respectively. The court unsealed the complaints on October 26, 2017.
The amended complaint alleges that Level 3, principally through two former employees, submitted false claims and made false statements to the government in connection with two government contracts. The relator seeks damages in this lawsuit of approximately $50 million, subject to trebling, plus statutory penalties, pre-and-post judgment interest, and attorney’s fees. The case is currently stayed.
Level 3 is evaluating its defenses to the claims. If, contrary to our expectations, the plaintiff obtains an award of the approximate magnitude he has claimed, the award would significantly exceed the reserve we have accrued for the matter. Such an outcome could have a material adverse effect on our results of operations in the period in which a liability is recognized and on our cash flows for the period in which any damages are paid.
Several people, including two former Level 3 employees, were indicted in the U.S. District Court for the Eastern District of Virginia on October 3, 2017, and charged with, among other things, accepting kickbacks from a subcontractor, who was also indicted, for work to be performed under a prime government contract. Of the two former employees, one entered into a plea agreement, and the other is deceased. Level 3 is fully cooperating in the government’s investigations in this matter.
Other Proceedings, Disputes and Contingencies
From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, regulatory hearings relating primarily to our rates or services, actions relating to employee
29

Table of Contents
claims, various tax issues, environmental law issues, grievance hearings before labor regulatory agencies and miscellaneous third-party tort actions.
We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities, many of which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial during 2021 if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers. As with all litigation, we are vigorously defending these actions and, as a matter of course, are prepared to litigate these matters to judgment, as well as to evaluate and consider all reasonable settlement opportunities.
We are subject to various foreign, federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $300,000 in fines and penalties.
The outcome of these other proceedings described under this heading is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on us.
The matters listed above in this Note do not reflect all of our contingencies. For additional information on our contingencies, see Note 17—Commitments, Contingencies and Other Items to the consolidated financial statements and accompanying notes in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2020. The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing above in this Note, and proceedings currently viewed as immaterial by us may ultimately materially impact us.

Overview
Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") included herein should be read in conjunction with MD&A and the other information included in our Annual Report on Form 10-K for the year ended December 31, 2020 and with the consolidated financial statements and related notes in Item 1 of Part I of this report. The results of operations and cash flows for the first three months of the year are not necessarily indicative of the results of operations and cash flows that might be expected for the entire year.
We are an international facilities-based technology and communications company focused on providing our business and mass markets customers with a broad array of integrated services and solutions necessary to fully participate in our rapidly evolving digital world. We believe we are the world's most inter-connected network and our platform empowers our customers to rapidly adjust digital programs to meet immediate demands, create efficiencies, accelerate market access, and reduce costs - allowing customers to rapidly evolve their IT programs to address dynamic changes without distraction from their core competencies. With approximately 450,000 route miles of fiber optic cable globally, we are among the largest providers of communications services to domestic and global enterprise customers. Our terrestrial and subsea fiber optic long-haul network throughout North America, Europe, Latin America and Asia Pacific connects to metropolitan fiber networks that we operate. We provide services in over 60 countries, with most of our revenue being derived in the United States. As of March 31, 2021, we had approximately 38,000 employees.
Impact of COVID-19 Pandemic
In response to the safety and economic challenges arising out of the COVID-19 pandemic and in a continued attempt to mitigate the negative impact on our stakeholders, we have taken a variety of steps to ensure the availability of our network infrastructure, to promote the safety of our employees and customers, to enable us to continue to adapt and provide our products and services worldwide to our customers, and to strengthen our communities. In addition to other actions described in our other reports, these steps include:
•establishing protocols for the safety of our on-site technicians and customers, including our "Safe Connections" program;
•adopting a rigorous employee work-from-home policy and substantially restricting non-essential business travel;
•continuously monitoring our network to enhance its ability to respond to changes in usage patterns;
•donating products or services in several of our communities to enhance their abilities to provide necessary support services; and
•taking steps to maintain our internal controls and the security of our systems and data in a remote work environment.

As the pandemic continues and vaccination rates increase, we expect to revise our responses or take additional steps to adjust to changed circumstances.
Social distancing, business and school closures, travel restrictions, and other actions taken in response to the pandemic have impacted us, our customers and our business since March 2020. In particular, as discussed further elsewhere herein, we have tracked pandemic impacts, including: (i) increases in certain revenue streams and decreases in others (including late fee revenue), (ii) increases in allowances for credit losses through the end of 2020, (iii) increases in overtime expenses, (iv) delays in our cost transformation initiatives and (v) an acceleration of our real estate rationalization efforts and the incurrence of related costs. Thus far, these changes have not materially impacted our financial performance or financial position, and, barring any unforeseen changes in conditions, we do not expect these changes to materially impact us during 2021. The impact of the pandemic during 2021 will materially depend on additional steps that we may take in response to the pandemic and various events outside of our control, including the pace of vaccinations worldwide, the length and severity of the health crisis and economic slowdown, actions taken by central banks, governmental agencies or legislative bodies, and the impact of those events on our employees, suppliers and customers. For additional information, see the risk factor disclosures referenced in Item 1A of Part II of this report.
For additional information on the impacts of the pandemic, see the remainder of this item, including "—Liquidity and Capital Resources — Overview of Sources and Uses of Cash," and "— Pension and Post-retirement Benefit Obligations."
Reporting Segments
As previously announced, we completed an internal reorganization of our reporting segments in January 2021. Our reporting segments are currently organized as follows, by customer focus:
•Business Segment: Under our Business segment, we provide our products and services under four sales channels:
◦International and Global Accounts ("IGAM"): Our IGAM sales channel includes multinational and enterprise customers. We provide our products and services to approximately 350 of our highest potential enterprise customers and to enterprises and carriers in three operating regions: Europe Middle East and Africa, Latin America and Asia Pacific.
◦Large Enterprise: Under our large enterprise sales channel, we provide our products and services to large enterprises and the public sector, including the U.S. Federal government, state and local governments and research and education institutions.
◦Mid-Market Enterprise: Under our mid-market enterprise sales channel, we provide our products and services to medium-sized enterprises directly and through our indirect channel partners.
◦Wholesale: Under our wholesale sales channel, we provide our products and services to a wide range of other communication providers across the wireline, wireless, cable, voice and data center sectors.
•Mass Markets Segment: Under our Mass Markets segment, we provide products and services to consumer and small business customers. At March 31, 2021, we served 4.7 million broadband subscribers under our Mass Markets segment.
See Note 11—Segment Information to our consolidated financial statements in Item 1 of Part I of this report for additional information.
We categorize our Business segment revenue among the following four products and services categories:
•Compute and Application Services, which include our Edge Cloud services, IT solutions, Unified Communications and Collaboration ("UC&C"), data center, content delivery network ("CDN") and Managed Security services;
34

Table of Contents
•IP and Data Services, which includes Ethernet, IP, and VPN data networks, including software-defined wide area networks ("SD WAN") based services, Dynamic Connections and Hyper WAN;
•Fiber Infrastructure Services, which includes dark fiber, optical services and equipment; and
•Voice and Other, which includes Time Division Multiplexing ("TDM") voice, private line and other legacy services.
Under our Mass Markets segment, we provide the following products and services:
•Consumer Broadband, which includes high speed fiber-based and lower speed DSL-based broadband services to residential customers;
•SBG Broadband, which includes high speed fiber-based and lower speed DSL-based broadband services to small businesses;
•Voice and Other, which include local and long-distance services, retail video services (including our linear TV services), state support and other ancillary services; and
•CAF II, which consists of Connect America Fund II support payments designed to reimburse us for various costs related to certain telecommunications services.
Trends Impacting Our Operations
In addition to the above-described impact of the pandemic, our consolidated operations have been, and are expected to continue to be, impacted by the following company-wide trends:
•Customers’ demand for automated products and services and competitive pressures will require that we continue to invest in new technologies and automated processes to improve the customer experience and reduce our operating expenses.
•The increasingly digital environment and the growth in online video require robust, scalable network services. We are continuing to enhance our product capabilities and simplify our product portfolio based on demand and profitability to enable customers to have access to greater bandwidth.
•Businesses continue to adopt distributed, global operating models. We are expanding and enhancing our fiber network, connecting more buildings to our network to generate revenue opportunities and reducing our reliance upon other carriers.
•Industry consolidation, coupled with changes in regulation, technology and customer preferences, are significantly reducing demand for our traditional voice services and are pressuring some other revenue streams through volume or rate reductions, while other advances, such as the need for lower latency provided by Edge computing or the implementation of 5G networks, are expected to create opportunities.
•The operating margins of several of our newer, more technologically advanced services, some of which may connect to customers through other carriers, are lower than the operating margins on our traditional, on-net wireline services.
•Declines in our traditional wireline services have necessitated right-sizing our cost structures to remain competitive.
Additional trends impacting our segments are discussed elsewhere in this Item 2.
Results of Operations
In this section, we discuss our overall results of operations and highlight special items that are not included in our segment results. In "Segment Results of Operations" we review the performance of our two reporting segments in more detail.

Basic earnings per common share | $ | 0.44 |  |  | 0.29 |
Diluted earnings per common share | $ | 0.44 |  |  | 0.29 |

For years, we have experienced revenue declines, excluding the impact of acquisitions, primarily due to declines in voice and private line customers, switched access rates and minutes of use. More recently, we have experienced declines in revenue derived from the sale of certain of our other products and services. To partially mitigate these revenue declines, we remain focused on efforts to, among other things:
•promote long-term relationships with our customers through bundling of integrated services;
•increase the size, capacity, speed and usage of our networks;
•provide a wide array of diverse services, including enhanced or additional services that may become available in the future due to, among other things, advances in technology or improvements in our infrastructure;
•provide our premium services to a higher percentage of our customers;
•pursue acquisitions of additional assets or divestitures of non-strategic assets, in each case if available at attractive prices;
•increase prices on our products and services if and when practicable; and
•market our products and services to new customers.
Consolidated Revenue

Cost of Services and Products (exclusive of depreciation and amortization)
Cost of services and products (exclusive of depreciation and amortization) decreased by $99 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. The decrease was primarily due to reductions in salaries and wages and employee-related expense from lower headcount and lower facility costs partially offset by higher network expenses.
Selling, General and Administrative
Selling, general and administrative expenses decreased by $97 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. This decrease was primarily due to reductions in salaries and wages and employee-related expense from lower headcount, lower bad debt expense, and lower marketing costs.

Depreciation expense decreased by $4 million for the three months ended March 31, 2021, as compared to the three months ended March 31, 2020 primarily due to the impact of annual rate depreciable life changes of $38 million, which was partially offset by $31 million of higher depreciation expense associated with net growth in depreciable assets.
Amortization expense decreased by $6 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily driven by decreases of $17 million from the use of accelerated amortization methods for a portion of the customer intangibles and $2 million from the impact of annual rate amortizable life changes on certain software, which were partially offset by $7 million additional amortization expense recognized as a result of reclassification of certain right-of-way assets, as discussed in Note 2—Goodwill, Customer Relationships and Other Intangible Assets to our consolidated financial statements in Item 1 of Part I of this report. The decrease in amortization expense was additionally offset by accelerated amortization for decommissioned applications of $4 million.
Further analysis of our segment operating expenses by segment is provided below in "Segment Results."
Goodwill Impairments
We are required to perform impairment tests related to our goodwill annually, which we perform as of October 31, or sooner if an indicator of impairment occurs.
The January 2021 completion of our previously announced internal reorganization was considered a change in event or circumstance which required an assessment of our goodwill for impairment. We performed a qualitative impairment assessment and concluded it is more likely than not that the fair value of each of our reporting units exceeds the carrying value of equity of our reporting units at January 31, 2021. Therefore, no impairment exists as of our assessment date.
See Note 2—Goodwill, Customer Relationships and Other Intangible Assets for further details on these tests and impairment charges.

Table of Contents
Interest Expense
Interest expense decreased by $60 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020. The decrease was primarily due to the decrease in average long-term debt from $34.7 billion to $31.6 billion and the decrease in the average interest rate of 5.34% to 4.88% for the three months ended March 31, 2020 compared to the three months ended March 31, 2021.
Other Income (Expense), Net
Other income (expense), net reflects certain items not directly related to our core operations, including (i) gains and losses on extinguishments of debt, (ii) components of net periodic pension and postretirement benefit costs, (iii) foreign currency gains and losses, and (iv) our share of income from partnerships we do not control, interest income, gains and losses from non-operating asset dispositions and other non-core items.

The significant change in pension and post retirement net periodic expense for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 was driven by a decline in interest cost due to lower discount rates.
Income Tax Expense
For the three months ended March 31, 2021 and March 31, 2020, our effective income tax rate was 24.8% and 27.5%, respectively.

Segment revenue decreased $142 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily due to the following factors:
40

Table of Contents
•Compute and Application Services declined primarily due to declines in Cloud Services within Large Enterprise and IGAM sales channels, lower rates for CDN and a large customer disconnect for IT Solutions within the IGAM sales channel, partially offset by growth in Managed Security and IT Solutions within the Large Enterprise sales channel;
•IP and Data Services declined due to lengthening sales cycles in the current environment for hybrid networks and SD-WAN, declines in traditional VPN networks in the Enterprise and IGAM sales channels and continued declines in Ethernet sales, partially offset by an increase in IP services;
•Fiber Infrastructure Services grew due to growth in dark fiber and wavelengths demand, primarily from our large IGAM customers, which was partially offset by lower equipment revenue in the Large Enterprise sales channel;
•Voice and Other decreased due to continued decline of legacy voice, private line and other services to customers across all sales channels.
Segment expense decreased $62 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily due to lower employee-related costs from lower headcount and lower cost of sales.
Segment adjusted EBITDA as a percentage of revenue was 67% for both the three months ended March 31, 2021 and 2020.

Segment revenue decreased $57 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020:
•Consumer Broadband revenue increases were driven by demand for higher-speed services and higher rates; and
•Voice and Other declined due to continued legacy voice customer losses and our de-emphasis of the Prism video product.
Segment expense decreased $13 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily due to lower employee-related costs from lower headcount and lower cost of sales driven by the decrease in Prism content costs.
Segment adjusted EBITDA as a percentage of revenue was 88% and 87% for the three months ended March 31, 2021 and 2020, respectively.

Liquidity and Capital Resources
Overview of Sources and Uses of Cash
We are a holding company that is dependent on the capital resources of our subsidiaries to satisfy our parent company liquidity requirements. Several of our significant operating subsidiaries have borrowed funds either on a standalone basis or as part of a separate restricted group with certain of its subsidiaries or affiliates. The terms of the instruments governing the indebtedness of these borrowers or borrowing groups may restrict our ability to access their accumulated cash. In addition, our ability to access the liquidity of these and other subsidiaries may be limited by tax, legal and other considerations.
At March 31, 2021, we held cash and cash equivalents of $486 million, and we also had $2.2 billion of borrowing capacity available under our revolving credit facility. We typically use our revolving credit facility as a source of liquidity for operating activities and our other cash requirements. We had approximately $119 million of cash and cash equivalents outside the United States at March 31, 2021. We currently believe that there are no material restrictions on our ability to repatriate cash and cash equivalents into the United States, and that we may do so without paying or accruing U.S. taxes. We do not currently intend to repatriate to the United States any of our foreign cash and cash equivalents from operating entities outside of Latin America.
Our executive officers and our Board of Directors periodically review our sources and potential uses of cash in connection with our annual budgeting process. Generally speaking, our principal funding source is cash from operating activities, and our principal cash requirements include operating expenses, capital expenditures, income taxes, debt repayments, dividends, periodic securities repurchases, periodic pension contributions and other benefits payments.
Based on our current capital allocation objectives, for the full year 2021 we project approximately $3.5 billion to $3.8 billion of capital expenditures and approximately $1.1 billion of cash dividends on our common stock (based on the assumptions described below under "Dividends").
For the 12 month period ending March 31, 2022, we project that our fixed commitments will include (i) $125 million of scheduled term loan amortization payments, (ii) $42 million of finance lease and other fixed payments and (iii) $3.7 billion of debt maturities.
For additional information, see "Risk Factors—Financial Risks" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.
Capital Expenditures
We incur capital expenditures on an ongoing basis to expand and improve our service offerings, enhance and modernize our networks and compete effectively in our markets. We evaluate capital expenditure projects based on a variety of factors, including expected strategic impacts (such as forecasted impact on revenue growth, productivity, expenses, service levels and customer retention) and our expected return on investment. The amount of capital investment is influenced by, among other things, current and projected demand for our services and products, cash flow generated by operating activities, cash required for other purposes and regulatory considerations (such as our CAF Phase II or Rural Digital Opportunity Fund ("RDOF") infrastructure buildout requirements).
Our capital expenditures continue to be focused on enhancing network operating efficiencies and supporting new service developments. For more information on our capital spending, see (i) "—Overview of Sources and Uses of Cash" above, (ii) "Historical Information—Investing Activities" below and (iii) Item 1 of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.
Debt and Other Financing Arrangements
Subject to market conditions, we expect to continue to issue debt securities from time to time in the future to refinance a substantial portion of our maturing debt, including issuing debt securities of certain of our subsidiaries to refinance their maturing debt to the extent feasible. The availability, interest rate and other terms of any new borrowings will depend on the ratings assigned by credit rating agencies, among other factors.
42

Table of Contents
As of March 31, 2021, the credit ratings for the senior secured and unsecured debt of Lumen Technologies, Inc., Level 3 Financing, Inc. and Qwest Corporation were as follows:

Borrower |  | Moody's Investors Service, Inc. |  | Standard & Poor's |  | Fitch Ratings
Lumen Technologies, Inc.: |  |  |  |  |  |
Unsecured |  | B2 |  | BB- |  | BB
Secured |  | Ba3 |  | BBB- |  | BB+
Level 3 Financing, Inc. |  |  |  |  |  |
Unsecured |  | Ba3 |  | BB |  | BB
Secured |  | Ba1 |  | BBB- |  | BBB-
Qwest Corporation: |  |  |  |  |  |
Unsecured |  | Ba2 |  | BBB- |  | BB+

Our credit ratings are reviewed and adjusted from time to time by the rating agencies. Any future downgrades of the senior unsecured or secured debt ratings of us or our subsidiaries could impact our access to capital or further raise our borrowing costs. See "Risk Factors—Financial Risks" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.
Net Operating Loss Carryforwards
As of December 31, 2020, Lumen Technologies had approximately $5.1 billion of federal net operating loss carryforwards ("NOLs"), which for U.S. federal income tax purposes can be used to offset future taxable income. These NOLs are primarily related to federal NOLs we acquired through the Level 3 acquisition on November 1, 2017 and are subject to limitations under Section 382 of the Internal Revenue Code and related U.S. Treasury Department regulations. We maintain a Section 382 rights agreement designed to safeguard through late 2023 our ability to use those NOLs. Assuming we can continue using these NOLs in the amounts projected, we expect to reduce our federal cash taxes for the next several years. The amounts of our near-term future tax payments will depend upon many factors, including our future earnings and tax circumstances and results of any corporate tax reform. Based on current laws and our current assumptions and projections, we estimate our cash income tax liability related to 2021 will be approximately $100 million.
We cannot assure you we will be able to use our NOL carryforwards fully. See "Risk Factors—Financial Risks—We may not be able to fully utilize our NOLs" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.
Dividends
We currently expect to continue our current practice of paying quarterly cash dividends in respect of our common stock subject to our Board of Directors' discretion to modify or terminate this practice at any time and for any reason without prior notice. Our current quarterly common stock dividend rate is $0.25 per share, as approved by our Board of Directors, which we believe is a dividend rate per share which enables us to balance our multiple objectives of managing our business, investing in the business, deleveraging our balance sheet and returning a substantial portion of our cash to our shareholders. Assuming continued payment during 2021 at this rate of $0.25 per share, our average total dividend paid each quarter would be approximately $273 million based on the number of our current outstanding shares (which figure (i) assumes no increases or decreases in the number of shares and (ii) includes dividend payments in connection with the anticipated vesting of currently outstanding equity awards). Dividend payments upon the vesting of equity incentive awards was $23 million during three months ended March 31, 2021. See Risk Factors—"Business Risks" in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020.

Revolving Facilities and Other Debt Instruments
On January 31, 2020, we amended and restated our credit agreement dated June 19, 2017 to, among other things, extend the debt maturities of the revolving credit and term loan facilities established thereunder, to lower interest rates payable thereunder, and to amend the amounts owed under each of the facilities. For additional information, see (i) "—Overview of Sources and Uses of Cash," (ii) Note 5—Long-Term Debt and Credit Facilities to our consolidated financial statements in Item 1 of Part I of this report and (iii) Note 6—Long-Term Debt and Credit Facilities in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2020.
At March 31, 2021, we had $64 million of letters of credit outstanding under our $225 million uncommitted letter of credit facility. Additionally, under a separate facility, we had outstanding letters of credit, or other similar obligations, of approximately $30 million as of March 31, 2021, of which $10 million was collateralized by cash that is reflected on our consolidated balance sheets as restricted cash.
In addition to its indebtedness under the Amended Credit Agreement, Lumen Technologies is indebted under its outstanding senior notes, and several of its subsidiaries are indebted under separate credit facilities or senior notes. For information on the terms and conditions of other debt instruments of ours and our subsidiaries, including financial and operating covenants, see (i) Note 5—Long-Term Debt and Credit Facilities to our consolidated financial statements in Item 1 of Part I of this report and (ii) "—Other Matters" below.
Pension and Post-retirement Benefit Obligations
We are subject to material obligations under our existing defined benefit pension plans and post-retirement benefit plans. At December 31, 2020, the accounting unfunded status of our qualified and non-qualified defined benefit pension plans and our qualified post-retirement benefit plans was $1.7 billion and $3.0 billion, respectively. For additional information about our pension and post-retirement benefit arrangements, see "Critical Accounting Policies and Estimates - Pensions and Post-Retirement Benefits" in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2020 and see Note 10—Employee Benefits to our consolidated financial statements in Item 8 of Part II of the same report.
Benefits paid by our qualified pension plan are paid through a trust that holds all of the plan's assets. Based on current laws and circumstances, we do not expect any contributions to be required for our qualified pension plan during 2021. The amount of required contributions to our qualified pension plan in 2022 and beyond will depend on a variety of factors, most of which are beyond our control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. We occasionally make voluntary contributions in addition to required contributions. We last made a voluntary contribution to the trust for our qualified pension plan during 2018. We may make a voluntary contribution to the trust for our qualified pension plan in 2021.
Substantially all of our post-retirement health care and life insurance benefits plans are unfunded and are paid by us with available cash. Aggregate benefits paid by us under these plans (net of participant contributions and direct subsidy receipts) were $211 million, $241 million and $249 million for the years ended December 31, 2020, 2019 and 2018, respectively. For additional information on our expected future benefits payments for our post-retirement benefit plans, please see Note 10—Employee Benefits to our consolidated financial statements in Item 8 of Part II of our Annual Report Form 10-K for the year ended December 31, 2020.
The capital markets have been volatile since early 2020, primarily as a result of uncertainties related to the COVID-19 outbreak. U.S. federal governmental actions to stimulate the economy have significantly impacted interest rates. These events could ultimately affect the funding levels of our pension plans and calculations of our liabilities under our pension and other post-employment benefit plans.
For 2021, our expected annual long-term rate of return on the pension plan assets is 5.5%. However, actual returns could be substantially different.
44

Table of Contents
Our pension plan contains provisions that allow us, from time to time, to offer lump sum payment options to certain former employees in settlement of their future retirement benefits. We record an accounting settlement charge, consisting of the recognition of certain deferred costs of the pension plan, associated with these lump sum payments only if, in the aggregate, they exceed the sum of the annual service and interest costs for the plan’s net periodic pension benefit cost, which represents the settlement accounting threshold. During 2020 and as of March 31, 2021, the settlement threshold was not reached.
Future Contractual Obligations
For information regarding our estimated future contractual obligations, see the MD&A discussion included in Item 7 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2020.
Federal Broadband Support Programs
Since 2015, we have been receiving over $500 million annually through Phase II of the CAF, a program that will end this year. In connection with the CAF funding, we must meet certain specified infrastructure buildout requirements in 33 states by the end of 2021, which requires substantial capital expenditures. While we are on track to meet the requirements this year, we cannot provide any assurances that we will be able to timely meet all of our mandated buildout requirements. In accordance with the Federal Communications Commission's ("FCC") January 2020 order, we elected to receive an additional year of CAF Phase II funding in 2021.
In early 2020, the FCC created the Rural Digital Opportunity Fund (the “RDOF”), which is a new federal support program designed to replace the CAF Phase II program. On December 7, 2020, the FCC allocated in its RDOF Phase I auction $9.2 billion in support payments over 10 years to deploy high speed broadband to over 5.2 million unserved locations. We won bids for RDOF Phase I support payments of $26 million, annually. These RDOF Phase I support payments are expected to begin January 1, 2022.
For additional information on these programs, see (i) "Business—Regulation" in Item 1 of Part I of our Annual Report on Form 10-K for the year ended December 31, 2020 and (ii) "Risk Factors—Risks Affecting Our Liquidity and Capital Resources" in Item 1A of Part I of the same Annual Report.
As part of its proposed infrastructure plan, the Biden Administration has proposed investing $100 billion to expand internet access in the United States. The plan seeks several other changes that could impact us, including proposals to increase competition among broadband providers. Currently, we believe it is premature to speculate on the potential impact of these proposals on us.
Historical Information
The following table summarizes our consolidated cash flow activities:

| Three Months Ended March 31, |  | $ Change
| 2021 |  | 2020 |
| (Dollars in millions)
Net cash provided by operating activities | $ | 1,525 |  |  | 1,299 |  |  | 226 |
Net cash used in investing activities | $ | (675) |  |  | (939) |  |  | (264) |
Net cash used in financing activities | $ | (774) |  |  | (486) |  |  | 288 |

Operating Activities
Net cash provided by operating activities increased by $226 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily due to higher net income, higher accrued payroll and accrued interest, and lower payments on accounts payable, partially offset by decreased collections on accounts receivable and increased cash payments for post-retirement benefits. Cash provided by operating activities is subject to variability period over period as a result of timing differences, including with respect to the collection of receivables and payments of interest expense, accounts payable and bonuses.
45

Table of Contents
Investing Activities
Net cash used in our investing activities decreased by $264 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020 primarily due to a decrease in capital expenditures.
Financing Activities
Net cash used in financing activities increased by $288 million for the three months ended March 31, 2021 as compared to the three months ended March 31, 2020, primarily due to higher proceeds from debt issuances in the first quarter of 2020 and the change in net activity of our revolving line of credit agreement, partially offset by a decrease in payments of long-term debt year-over-year.
See Note 5—Long-Term Debt and Credit Facilities to our consolidated financial statements in Item 1 of Part I of this report for additional information on our outstanding debt securities.
Other Matters
We have cash management and loan arrangements with a majority of our income-generating subsidiaries, in which a substantial portion of the aggregate cash of those subsidiaries' is periodically advanced or loaned to us or our service company affiliate. Although we periodically repay these advances to fund the subsidiaries' cash requirements throughout the year, at any given point in time we may owe a substantial sum to our subsidiaries under these arrangements. In accordance with generally accepted accounting principles, these arrangements are reflected in the balance sheets of our subsidiaries but are eliminated in consolidation and therefore not recognized on our consolidated balance sheets.
We also are involved in various legal proceedings that could substantially impact our financial position. See Note 12—Commitments, Contingencies and Other Items for additional information.
Market Risk
As of March 31, 2021, we are exposed to market risk from changes in interest rates on our variable rate long-term debt obligations and fluctuations in certain foreign currencies. We seek to maintain a favorable mix of fixed and variable rate debt in an effort to limit interest costs and cash flow volatility resulting from changes in rates.
Management periodically reviews our exposure to interest rate fluctuations and periodically implements strategies to manage the exposure. From time to time, we have used derivative instruments to (i) swap our exposure to changing variable interest rates for fixed interest rates or (ii) to swap obligations to pay fixed interest rates for variable interest rates. We have established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative instrument activities. As of March 31, 2021, we did not hold or issue derivative financial instruments for trading or speculative purposes.
In 2019, we executed swap transactions that reduced our exposure to floating rates with respect to $4.0 billion principal amount of floating rate debt. See Note 10—Derivative Financial Instruments to our consolidated financial statements in Item 1 of Part I of this report for additional disclosure regarding our hedging arrangements.
As of March 31, 2021, we had approximately $9.7 billion floating rate debt potentially subject to LIBOR, $4.0 billion of which was subject to the above-described hedging arrangements. A hypothetical increase of 100 basis points in LIBOR relating to our $5.7 billion of unhedged floating rate debt would, among other things, decrease our annual pre-tax earnings by approximately $57 million.
We conduct a portion of our business in currencies other than the U.S. dollar, the currency in which our consolidated financial statements are reported. Our European subsidiaries and certain Latin American subsidiaries use the local currency as their functional currency, as the majority of their revenue and purchases are transacted in their local currencies. Certain Latin American countries previously designated as highly inflationary economies use the U.S. dollar as their functional currency. Although we continue to evaluate strategies to mitigate risks related to the effect of fluctuations in currency exchange rates, we will likely recognize gains or losses from international

transactions. Accordingly, changes in foreign currency rates relative to the U.S. dollar could adversely impact our operating results.
Certain shortcomings are inherent in the method of analysis presented in the computation of exposures to market risks. Actual values may differ materially from those disclosed by us from time to time if market conditions vary from the assumptions used in the analyses performed. These analyses only incorporate the risk exposures that existed at March 31, 2021.

ITEM 4. CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934 (the “Exchange Act”)) designed to provide reasonable assurance that the information required to be disclosed by us in the reports we file under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. These include controls and procedures designed to ensure this information is accumulated and communicated to our senior management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Management, with the participation of our Chief Executive Officer, Jeff K. Storey, and our Executive Vice President and Chief Financial Officer, Indraneel Dev, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2021. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded our disclosure controls and procedures were effective, as of March 31, 2021, in providing reasonable assurance the information required to be disclosed by us in this report was accumulated and communicated in the manner provided above.
Changes in Internal Control Over Financial Reporting
There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) of the Exchange Act) that occurred during the first quarter of 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations of Internal Controls
The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing and evaluating the controls and procedures, the assumptions used in identifying the likelihood of future events and the inability to eliminate misconduct completely. As a result, there can be no assurance that our disclosure controls and procedures will detect all errors or fraud. By their nature, our or any system of disclosure controls and procedures can provide only reasonable assurance regarding management's control objectives.

ITEM 5. OTHER INFORMATION
As we continue to evaluate our disclosure obligations under Section 13(r) of the Exchange Act in connection with the matter outlined below, the following disclosure is being made under Section 13(r) of the Exchange Act out of an abundance of caution:
We are required to engage on a regular basis with the Russian Federal Security Service (“FSB”) in the FSB’s official capacity of regulating our use of technology in Russia in connection with providing commercial services therein through our local subsidiary. On March 2, 2021, the U.S. Secretary of State designated the FSB as a party subject to the provisions of U.S. Executive Order No. 13382 issued in 2005. There are no gross revenues or net profits directly associated with any such dealings by us with the FSB and all such dealings are explicitly authorized by General License 1B issued by the U.S. Department of the Treasury’s Office of Foreign Assets Control. We plan to continue these activities as required to continue to provide commercial services in Russia.
