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 and 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 and other initiatives, including synergies or costs associated with our transformational initiatives, acquisitions or dispositions, and the impact of our participation in government programs;

• | 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, debt 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 due to events outside of our control regarding the impact that COVID-19 health and economic disruptions will have on our business, operations, employees, customers, suppliers, distribution channels, controls, regulatory environment, access to capital, operating or capital plans and corporate initiatives, and ultimately on our financial performance, financial position and cash flows;

• | 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 safeguard our network, and to avoid the adverse impact on our business from possible security breaches, service outages, system failures, equipment breakage, or similar events impacting our network or the availability and quality of our services;

• | the effects of ongoing changes in the regulation of the communications industry, including the outcome of regulatory or judicial proceedings relating to intercarrier compensation, interconnection obligations, special access, universal service, broadband deployment, data protection and net neutrality;

• | our ability to effectively adjust to changes in the communications industry and changes in the composition of our markets and product mix;

Table of Contents

• | possible changes in the demand for our products and services, including increased demand for high-speed data transmission services over the past few years and more recent changes that could result from disruptions caused by the COVID-19 pandemic;

• | our ability to successfully maintain the quality and profitability of our existing product and service offerings and to introduce profitable new offerings on a timely and cost-effective basis;

• | 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 implement our operating plans and corporate strategies, including our delevering strategy;

• | changes in our operating plans, corporate strategies or capital allocation plans, whether based upon COVID-19 disruptions, changes in our cash flows, cash requirements, financial performance, financial position, market conditions or otherwise;

• | our ability to effectively retain and hire key personnel and to successfully negotiate collective bargaining agreements on reasonable terms without work stoppages;

• | the negative impact of increases in the costs of CenturyLink’s 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 debt credit ratings, unstable markets or otherwise;

• | our ability to meet the terms and conditions of our debt obligations and covenants, including our ability to make transfers of cash in compliance therewith;

• | our ability to maintain favorable relations with our key business partners, suppliers, vendors, landlords and financial institutions;

• | our ability to collect our receivables from, or continue to do business with, financially troubled customers, including but not limited to those adversely impacted by the economic dislocations caused by the COVID-19 pandemic;

• | any adverse developments in legal or regulatory proceedings involving us or our affiliates, including CenturyLink;

• | changes in tax, communications, pension, healthcare or other laws or regulations, in governmental support programs, or in general government funding levels;

• | 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 or other natural or man-made disasters;

• | the potential adverse effect 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 set forth or referenced in "Risk Factors" in Item 1A of Part II 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)
Unless the context requires otherwise, references in this report to "QC" refer to Qwest Corporation, references to "Qwest," "we," "us," and "our" refer to Qwest Corporation and its consolidated subsidiaries, references to "QSC" refer to our direct parent company, Qwest Services Corporation and its consolidated subsidiaries, and references to "CenturyLink" refer to our ultimate parent company, CenturyLink, Inc. and its consolidated subsidiaries including Level 3 Parent, LLC, referred to as "Level 3".
(1) Background
General
We are an integrated communications company engaged primarily in providing a broad array of communications services to our residential and business customers. Our specific products and services are detailed in Note 7—Products and Services Revenue of this report.
We generate the majority of our total consolidated operating revenue from services provided in the 14-state region of Arizona, Colorado, Idaho, Iowa, Minnesota, Montana, Nebraska, New Mexico, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming. We refer to this region as our local service area.
Basis of Presentation
Our consolidated balance sheet as of December 31, 2019, 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 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, 2019.
The accompanying consolidated financial statements include our accounts and the accounts of our subsidiaries. Intercompany amounts and transactions with our consolidated subsidiaries have been eliminated. Transactions with our non-consolidated affiliates (referred to herein as affiliates) have not been eliminated.
We reclassified certain prior period amounts to conform to the current period presentation, including the categorization of our revenue and expenses for the three months ended March 31, 2020 and 2019.
Segments
Our operations are integrated into and reported as part of CenturyLink. CenturyLink's chief operating decision maker ("CODM") is our CODM but reviews our financial information on an aggregate basis only in connection with our quarterly and annual reports that we file with the SEC. Consequently, we do not provide our discrete financial information to the CODM on a regular basis. As such, we have one reportable segment.
Change in Accounting Policy
During the first quarter of 2020, we elected to change the presentation for taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, including federal and certain state Universal Service Fund ("USF") regulatory fees, to present all such taxes on a net basis in our statement of operations. Prior to the first quarter of 2020, we assessed whether we were the primary obligor or principal taxpayer for the taxes assessed in each jurisdiction where we do business. The previous policy resulted in presenting such USF fees on a gross basis within operating revenue and cost of services and products, and all other significant taxes on a net basis. This change in accounting policy was applied retrospectively and decreased
11

Table of Contents
both operating revenue and cost of services and products by $25 million for both quarters ended March 31, 2020 and March 31, 2019. The change had no impact on operating income or net income in the consolidated statements of operations.
We changed our policy to present such taxes on the net basis and believe the new policy is preferable because of the historical and potential future regulatory rate changes outside of our control resulting in significant variability in tax and fee revenue that are not indicative of our operating performance. We believe that net presentation provides the most useful and transparent financial information and improves comparability and consistency of financial results.
Operating Lease Income
Qwest leases various data transmission capacity, office facilities, switching facilities and other network sites to third parties under operating leases. Lease and sublease income are included in operating revenue in the consolidated statements of operations.
For the three months ended March 31, 2020 and 2019, our gross rental income was $79 million and $81 million, respectively, which represents approximately 4% of our operating revenue for both the three months ended March 31, 2020 and 2019.
Recently Adopted Accounting Pronouncements
Financial Instruments
In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Instruments". The primary impact of ASU 2016-13 for us is a change in the model for the recognition of credit losses related to our financial instruments from an incurred loss model, which recognized credit losses only if it was probable that a loss had been incurred, to an expected loss model, which requires our management team to estimate the total credit losses expected on the portfolio of financial instruments.
We adopted ASU 2016-13 on January 1, 2020 and recognized a cumulative adjustment to our retained earnings as of the date of adoption of $3 million net of tax effect. Please refer to Note 4—Credit Losses on Financial Instruments for more information.
Recently Issued Accounting Pronouncements
In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 removes certain exceptions for investments, intra-period allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. ASU 2019-12 will become effective for us in the first quarter of fiscal 2021 and early adoption is permitted. We are evaluating the impact the adoption will have on our consolidated financial statements.
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. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. Therefore, it will be in effect for a limited time through December 31, 2022. We are evaluating the optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued and the related impact on our consolidated financial statements.

(2) Goodwill, Customer Relationships and Other Intangible Assets
Goodwill, customer relationships and other intangible assets consisted of the following:

| March 31, 2020 |  | December 31, 2019
| (Dollars in millions)
Goodwill | $ | 9,360 |  |  | 9,360 |
Customer relationships, less accumulated amortization of $5,330 and $5,231 | $ | 369 |  |  | 468 |
Other intangible assets, less accumulated amortization of $1,802 and $1,780 | $ | 313 |  |  | 311 |

Substantially, all of our goodwill was derived from CenturyLink's acquisition of us where the purchase price exceeded the fair value of the net assets acquired.
We assess our goodwill 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 in periods in which the carrying value of equity exceeds the estimated fair value of equity, limited to the amount of goodwill. Our annual impairment assessment date for goodwill is October 31, at which date we assessed goodwill at our reporting unit. In reviewing the criteria for reporting units, we have determined that we are one reporting unit.
Because CenturyLink's low stock price was a trigger for impairment testing, we estimated the fair value of our operations using only the market approach in the quarter ended March 31, 2019. Applying this approach, we utilized company comparisons and analyst reports within the telecommunications industry, which have historically supported a range of fair values of annualized revenue and EBITDA multiples between 2.1x and 4.9x and 4.9x and 9.8x, respectively. We selected a revenue and EBITDA multiple within this range. As of March 31, 2019, based on our assessments performed as described above, we concluded that our goodwill was not impaired as of that date.
The market multiples approach that we used in the quarter ended March 31, 2019 incorporated significant estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of certain cost synergies. In developing the market multiple, we also considered observed trends of our industry participants. Our assessment included many qualitative factors that required significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the size of our impairments.
During the first quarter of 2020, we observed a decline in CenturyLink's stock price as a result of events occurring after the end of 2019, including the COVID-19 pandemic. We evaluated whether such events would indicate the fair value of our reporting unit was below its carrying value. We believe these events have impacted the global economy more directly than us, and when considered with other factors, we have concluded it is not more likely than not that the fair value of our reporting unit was less than its carrying value as of the quarter ended March 31, 2020. In light of the negative impacts of COVID-19 on the global economy, we will continue to evaluate the general economic trends which could have an impact on our assessment of whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. Future changes could cause our reporting unit fair value to be less than its carrying value, resulting in potential impairments of our goodwill which could have a material effect on our results of operations and financial condition. The extent of the impact, if any, will depend on future developments including actions taken to contain the coronavirus and its long-term impacts on the overall economy.
As of March 31, 2020, the gross carrying amount of goodwill, customer relationships and other intangible assets was $17.2 billion. The total amortization expense for intangible assets for the three months ended March 31, 2020 and 2019 totaled $124 million and $137 million, respectively.
13

Table of Contents
We estimate that total amortization expense for intangible assets for the years ending December 31, 2020 through 2024 will be as follows:

| (Dollars in millions)
2020 (remaining nine months) | $ | 359 |
2021 | 154 |
2022 | 52 |
2023 | 42 |
2024 | 33 |

(3) Revenue Recognition
Reconciliation of Total Revenue to Revenue from Contracts with Customers
The following table provides the amount of revenue that is not subject to ASC 606, but is instead governed by other accounting standards:

| Three Months Ended March 31,
| 2020 |  | 2019
| (Dollars in millions)
Total revenue (1) | $ | 1,918 |  |  | 2,030 |
Adjustments for non-ASC 606 revenue (2) | (121 | ) |  | (127 | )
Total revenue from contracts with customers | $ | 1,797 |  |  | 1,903 |

______________________________________________________________________

(1) | Reclassifications were made within certain 2019 comparative figures due to the retrospective application of an accounting policy election during the first quarter of 2020. Refer to Note 1—Background and our Form 8-K filing dated May 7, 2020 for further information.

(2) | Includes regulatory revenue, lease revenue, sublease rental income and revenue from fiber capacity lease arrangements which are not within the scope of ASC 606.

Customer Receivables and Contract Balances
The following table provides balances of customer receivables, contract assets and contract liabilities as of March 31, 2020 and December 31, 2019:

| March 31, 2020 |  | December 31, 2019
| (Dollars in millions)
Customer receivables (1) | $ | 415 |  |  | 430 |
Contract liabilities | 337 |  |  | 338 |
Contract assets | 15 |  |  | 18 |

______________________________________________________________________

(1) | Gross customer receivables of $444 million and $462 million, net of allowance for doubtful accounts of $29 million and $32 million, at March 31, 2020 and December 31, 2019, respectively.

Contract liabilities consist of 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 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, 2020 and March 31, 2019, we recognized $184 million and $261 million, respectively, of revenue that was included in contract liabilities as of January 1, 2020 and January 1, 2019, respectively.
Performance Obligations
14

Table of Contents
As of March 31, 2020, our estimated revenue expected to be recognized in the future related to performance obligations associated with customer contracts that are unsatisfied (or partially satisfied) is approximately $163 million. We expect to recognize approximately 99% of this revenue through 2022, with the balance recognized thereafter.
We do not disclose 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), or 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, 2020 |  | Three Months Ended March 31, 2019
| Acquisition Costs |  | Fulfillment Costs |  | Acquisition Costs |  | Fulfillment Costs
| (Dollars in millions)
Beginning of period balance | $ | 86 |  |  | 64 |  |  | 90 |  |  | 57 |
Costs incurred | 14 |  |  | 6 |  |  | 16 |  |  | 4 |
Amortization | (16 | ) |  | (9 | ) |  | (16 | ) |  | (4 | )
End of period balance | $ | 84 |  |  | 61 |  |  | 90 |  |  | 57 |

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 communications 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 30 months for consumer customers and average contract life of 29 months for 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 twelve months are included in other current assets on our consolidated balance sheets. The amount of deferred costs expected to be amortized beyond the next twelve 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" ("ASC 326") we aggregate financial assets with similar risk characteristics such that expected credit losses reflect the credit quality or deterioration over the life of the asset. 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.
In developing our accounts receivable portfolio, 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.
Prior to the adoption of the new credit loss standard, the allowance for doubtful accounts receivable reflected our best estimate of probable losses inherent in our receivable portfolio determined based on historical experience, specific allowances for known troubled accounts, and other currently available evidence.
We implemented the new standard, using a loss rate method to estimate our allowance for credit losses. Our current expected credit loss rate begins with the use of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to move accounts receivable to credit loss. When asset specific characteristics and current conditions change from those in the historical period, due to
15

Table of Contents
changes in our credit and collections strategy or credit loss and recovery policies, we perform a qualitative and quantitative assessment to update our current loss rate, which as noted below has increased due to an increase in historic loss experience and weakening economic forecasts. 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. The historical, current, and expected credit loss rates are combined and applied to period end accounts receivable, which results in our allowance for credit losses.
If there is a deterioration of a customer's financial condition or if future default rates in general, including impacts of COVID-19, differ from those currently anticipated, we may have 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 forecast 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 customer's actual default in the future.
The following table presents the activity of our allowance for credit losses by accounts receivable portfolio:

| (Dollars in millions)
Beginning balance at January 1, 2020 (1) | $ | 35 |
Current period provision for expected losses | 13 |
Write-offs charged against the allowance | (16 | )
Recoveries collected | 5 |
Ending Balance at March 31, 2020 | $ | 37 |

______________________________________________________________________

(1) | The beginning balance includes the cumulative effect of the adoption of new credit loss standard

For the three months ended March 31, 2020, our allowance for credit losses for our business and consumer accounts receivable portfolio increased due to an increase in historical loss experience and weakening economic forecasts, partially offset by recoveries.

Table of Contents
(1) Qwest Corporation's Term Loan had an interest rate of 2.990% as of March 31, 2020 and 3.800% as of December 31, 2019
Redemption of Senior Notes
On January 15, 2020, Qwest Corporation fully redeemed all $850 million aggregate principal amount of its outstanding 6.875% senior notes due 2033 and all $250 million aggregate principal amount of its outstanding 7.125% senior notes due 2043 which resulted in a loss of $12 million.
Note Payable - Affiliate
On September 30, 2017, Qwest Corporation entered into an amended and restated revolving promissory note in the amount of $965 million with an affiliate of our ultimate parent company, CenturyLink, Inc. This note replaced and amended the original $1.0 billion revolving promissory note Qwest Corporation entered into on April 18, 2012 with the same affiliate. The outstanding principal balance owed by Qwest Corporation under this revolving promissory note and the accrued interest thereon is due and payable on demand, but if no demand is made, then on June 30, 2022. Interest is accrued on the outstanding balance during an interest period using a weighted average per annum interest rate on the consolidated outstanding debt of CenturyLink and its subsidiaries. As of March 31, 2020, the amended and restated revolving promissory note had an outstanding balance of $1.100 billion and bore interest at a weighted-average interest rate of 5.561%. As of March 31, 2020 and December 31, 2019, the amended and restated revolving promissory note is reflected on our consolidated balance sheets as a current liability under "Note payable - affiliate". In accordance with the terms of the amended and restated revolving promissory note, interest shall be assessed on June 30th and December 31st (an "Interest Period"). Any assessed interest for an Interest Period that remains unpaid on the last day of the subsequent Interest Period is to be capitalized on such date and is to begin accruing interest. Through March 31, 2020, $136 million of such interest has been capitalized. As of March 31, 2020, $15 million of accrued interest is reflected in other current liabilities on our consolidated balance sheet.
Aggregate Maturities of Long-Term Debt
Set forth below is the aggregate principal amount of our long-term debt (excluding unamortized premiums and discounts and unamortized debt issuance costs and excluding note payable-affiliate) maturing during the following years:

other obligations. Due to their short-term nature, the carrying amounts of our cash, cash equivalents and restricted cash, accounts receivable, advances to affiliates, accounts payable and note-payable-affiliate approximate their fair values.
The three input levels in the hierarchy of fair value measurements are defined by the Fair Value Measurement and Disclosure framework 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 long-term debt, excluding finance lease and other obligations, as well as the input level used to determine the fair values indicated below:

(7) Products and Services Revenue
We are an integrated communications company engaged primarily in providing an array of communications services, including local voice, broadband, private line (including business data services), Ethernet, network access, information technology and other ancillary services. We strive to maintain our customer relationships by, among other things, bundling our service offerings to provide our customers with a complete offering of integrated communications services.
We categorize our products, services and revenue among the following six categories:

• | IP and Data Services, which include primarily VPN data networks, Ethernet, IP and other ancillary services;

• | Transport and Infrastructure, which include broadband, private line (including business data services) and other ancillary services;

• | Voice and Collaboration, which includes primarily local voice, including wholesale voice, and other ancillary services;

• | IT and Managed Services, which include information technology services and managed services, which may be purchased in conjunction with our other network services;

• | Regulatory Revenue, which consist of Connect America Fund ("CAF") support payments and other operating revenue. We receive federal support payments from the federal CAF program. These support payments are government subsidies designed to reimburse us for various costs related to certain telecommunications services including the costs of deploying, maintaining and operating voice and broadband infrastructure in high-cost rural areas where we are not able to fully recover our costs from our customers; and

• | Affiliate Services, which are telecommunication services that we also provide to external customers. In addition, we provide to our affiliates computer system development and support services, network support and technical services.

From time to time, we may change the categorization of our products and services.

(1) | Reclassifications were made within certain 2019 comparative figures due to the retrospective application of an accounting policy election during the first quarter of 2020, in addition to product reclassification changes. Refer to Note 1—Background and our Form 8-K filing dated May 7, 2020 for further information.

(8) 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, 2020 aggregated to approximately $26 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
Switched Access Disputes
Subsidiaries of CenturyLink, Inc., including us, are among hundreds of companies involved in an industry-wide dispute, raised in nearly 100 federal lawsuits (filed between 2014 and 2016) that have been consolidated in the United States District Court for the Northern District of Texas for pretrial procedures. The disputes relate to switched access charges that local exchange carriers ("LECs") collect from interexchange carriers ("IXCs") for IXCs' use of LEC's access services. In the lawsuits, IXCs, including Sprint Communications Company L.P. ("Sprint") and various affiliates of Verizon Communications Inc. ("Verizon"), assert that federal and state laws bar LECs from collecting access charges when IXCs exchange certain types of calls between mobile and wireline devices that are routed through an IXC. Some of these IXCs have asserted claims seeking refunds of payments for access charges previously paid and relief from future access charges.
19

Table of Contents
In November 2015, the federal court agreed with the LECs and rejected the IXCs' contention that federal law prohibits these particular access charges, and also allowed the IXCs to refile state-law claims. Since then, many of the LECs and IXCs have filed revised pleadings and additional motions, which remain pending. Separately, some of the defendants, including us, have petitioned the FCC to address these issues on an industry-wide basis.
The outcome of these disputes and lawsuits, as well as any related regulatory proceedings that could ensue, are currently not predictable.
Billing Practices Suits
In June 2017, a former employee of CenturyLink filed an employment lawsuit against CenturyLink claiming that she was wrongfully terminated for alleging that CenturyLink charged some of its retail customers for products and services they did not authorize. Starting shortly thereafter and continuing since then, and based in part on the allegations made by the former employee, several legal proceedings have been filed.
In June 2017, McLeod v. CenturyLink, a putative consumer class action, was filed against CenturyLink in the U.S. District Court for the Central District of California alleging that it charged some of its retail customers for products and services they did not authorize. Other complaints asserting similar claims have been filed in other federal and state courts, as well. The lawsuits assert claims including fraud, unfair competition, and unjust enrichment. Also, in June 2017, Craig. v. CenturyLink, Inc., et al., a putative securities investor class action, was filed in U.S. District Court for the Southern District of New York, alleging that it failed to disclose material information regarding improper sales practices, and asserting federal securities law claims. A number of other cases asserting similar claims have also been filed.
Beginning June 2017, CenturyLink received several shareholder derivative demands addressing related topics. In August 2017, CenturyLink's Board of Directors formed a special litigation committee of outside directors to address the allegations of impropriety contained in the shareholder derivative demands. In April 2018, the special litigation committee concluded its review of the derivative demands and declined to take further action. Since then, derivative cases were filed in Louisiana state court in the Fourth Judicial District Court for the Parish of Ouachita and in federal court in Louisiana and Minnesota. These cases have been brought on behalf of CenturyLink against certain current and former officers and directors of the Company and seek damages for alleged breaches of fiduciary duties.
The consumer putative class actions, the securities investor putative class actions, and the federal derivative actions have been 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. Subject to confirmatory discovery and court approval, CenturyLink agreed to settle the consumer putative class actions for payments of $15.5 million to compensate class members and of up to $3.5 million for administrative costs. In the second quarter of 2019, CenturyLink accrued for these obligations, and a portion of the administrative costs has been expended in 2020. Certain class members may elect to opt out of the class settlement and pursue the resolution of their individual claims against us on these issues through various dispute resolution processes, including individual arbitration. One law firm claims to represent more than 22,000 potential class members. To the extent that a substantial number of class members, including many of the law firm’s alleged clients, meet the contractual requirements to arbitrate, elect to opt out of the settlement (or otherwise successfully exclude their individual claims), and actually pursue arbitrations, CenturyLink and we could incur a material amount of filing and other arbitrations fees in relation to the administration of those claims.
In July 2017, the Minnesota state attorney general filed State of Minnesota v. CenturyTel Broadband Services LLC, et al. in the Anoka County Minnesota District Court, alleging claims of fraud and deceptive trade practices relating to improper consumer sales practices.
CenturyLink has engaged in discussions regarding potential resolutions of these claims with a number of state attorneys general, and have entered into agreements settling the Minnesota suit and certain of the consumer practices claims asserted by state attorneys general. While CenturyLink does not agree with allegations raised in these matters, it has been willing to consider reasonable settlements where appropriate.
Locate Service Investigations
20

Table of Contents
In June 2019, Minnesota and Arizona initiated investigations related to the timeliness of responses by certain of our vendors to requests for marking the location of underground telecommunications facilities. We, along with CenturyLink and its other subsidiaries are cooperating with the investigations. In February 2020, the Minnesota claims were settled. The terms of the settlement were not material to our consolidated results of operations or financial position.
Other Proceedings, Disputes and Contingencies
From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, administrative hearings of state public utility commissions relating primarily to our rates or services, actions relating to employee 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 2020 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 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 $100,000 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 16—Commitments, Contingencies and Other Items to the financial statements included in Item 8 of Part II of our annual report on Form 10-K for the year ended December 31, 2019. 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.
(9) Dividends
From time to time we may declare and pay dividends to our direct parent company, QSC, sometimes in excess of our earnings to the extent permitted by applicable law. Our debt covenants do not currently limit the amount of dividends we can pay to QSC.
During the three months ended March 31, 2020 and 2019, we declared and paid dividends of $500 million and $350 million, respectively, to QSC. Dividends paid are reflected on our consolidated statements of cash flows as financing activities.

(11) Labor Union Contracts
As of March 31, 2020, approximately 46% of our employees were represented by the Communication Workers of America ("CWA") or the International Brotherhood of Electrical Workers ("IBEW"). During the third quarter of 2019, we reached new agreements with the CWA and IBEW, which represented all of the above noted represented employees. Therefore, there are no collective bargaining agreements that are scheduled to expire over the next 12 months. We believe relations with our employees continue to be generally good.

Unless the context requires otherwise, references in this report to "QC" refer to Qwest Corporation, and references to "Qwest," "we," "us" and "our" refer to Qwest Corporation and its consolidated subsidiaries.
All references to "Notes" in this Item 2 of Part I refer to the Notes to Consolidated Financial Statements included in Item 1 of Part I of this report.
Certain statements in this report constitute forward-looking statements. See "Special Note Regarding Forward-Looking Statements" appearing at the beginning of this report and "Risk Factors" set forth or referenced in Item 1A of Part II of this report or other of our filings with the SEC for a discussion of certain factors that could cause our actual results to differ from our anticipated results or otherwise impact our business, financial condition, results of operations, liquidity or prospects.
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, 2019, and with the consolidated financial statements and related notes in Item 1 of Part I of this report. The results of operations for the first three months of the year are not necessarily indicative of the results of operations that might be expected for the entire year.
We are an integrated communications company engaged primarily in providing an array of communications services to our business and residential customers. Our specific products and services are detailed in Note 7—Products and Services Revenue of this report.
Our ultimate parent company, CenturyLink, Inc. ("CenturyLink"), has cash management arrangements between certain of its subsidiaries that include lines of credit, affiliate obligations, capital contributions and dividends. As part of these cash management arrangements, affiliates provide lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is advanced on a daily basis for centralized management by CenturyLink's service company affiliate. From time to time we may declare and pay dividends to Qwest Services Corporation ("QSC"), our direct parent, using cash owed to us under these advances, which has the net effect of reducing the amount of these advances. We report the balance of these transfers on our consolidated balance sheet as advances to affiliates.
At March 31, 2020, we served approximately 3.0 million broadband subscribers. Our methodology for counting broadband subscribers may not be comparable to those of other companies.
Impact of COVID-19 Pandemic
In response to the safety and economic challenges arising out of the COVID-19 pandemic, we have taken a variety of steps to ensure the availability of our network infrastructure, to promote the safety of our employees, to enable us to continue to provide our products and services worldwide to our customers, and to strengthen our communities. These steps include:

• | CenturyLink taking the FCC’s “Keep Americans Connected Pledge,” which obligates us in certain circumstances to waive late fees and to forego certain service terminations;

• | establishing new 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

23

Table of Contents

• | taking steps to maintain our internal controls and the security of our systems and data in a remote work environment.

As the crisis continues, we may revise our responses or take additional steps to adjust to changed circumstances.
By the end of the first quarter of 2020, social distancing, travel restrictions, business and school closures, and other actions taken in response to the pandemic had begun to impact us, our customers and our business. In particular, the pandemic has reduced our late fee revenues. However, most of those changes impacted only the latter portions of the first quarter of 2020. We expect that pandemic-related changes will have a more pronounced impact on our second quarter 2020 operating results, especially if the economic slowdown adversely impacts our customers' ability and willingness to order and pay for our products and services. The impact of those changes after the second quarter of 2020 will materially depend on additional steps that we may take in response to the pandemic and various events outside of our control, including the duration of the health crisis, the length and severity of the economic slowdown, actions taken by 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 set forth or 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 — Pension and Post-retirement Benefit Obligations" and "Connect America Fund."
For the reasons noted in Note 1—Background to our consolidated financial statements in Item 1 of Part I of this report, we believe we have one reportable segment.
We categorize our products, services and revenue among the following six categories:

• | IP and Data Services, which include primarily VPN data networks, Ethernet, IP and other ancillary services;

• | Transport and Infrastructure, which include broadband, private line (including business data services) and other ancillary services;

• | Voice and Collaboration, which includes primarily local voice, including wholesale voice, and other ancillary service;

• | IT and Managed Services, which include information technology services and managed services, which may be purchased in conjunction with our other network services;

• | Regulatory Revenue, which consist of Connect America Fund ("CAF") support payments and other operating revenue. We receive federal support payments from the federal CAF program; and

• | Affiliate Services, which are telecommunication services that we also provide to external customers. In addition, we provide to our affiliates, computer system development and support services, network support and technical services.

From time to time, we may change the categorization of our products and services.
The following analysis is organized to provide the information we believe will be useful for understanding material trends affecting our business.

Total operating revenue decreased by $112 million, or 6%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease in our operating revenue was primarily due to decreases in all of our revenue categories.

Cost of Services and Products (exclusive of depreciation and amortization)
Cost of services and products (exclusive of depreciation and amortization) decreased by $109 million, or 19%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease in our cost of services and products (exclusive of depreciation and amortization) was primarily due to reductions in salaries and wages and employee-related expenses resulting from lower headcount and professional services. These reductions were offset by higher customer installation expenses and equipment maintenance expense.
Selling, General and Administrative
Selling, general and administrative expenses decreased by $14 million, or 9%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease in our selling, general and administrative expenses was primarily due to reductions in salaries and wages and employee-related expenses from lower headcount, contract labor costs, marketing and advertising and an increase in the amount of labor capitalized or deferred. These reductions were partially offset by higher professional fees.
Operating Expenses - Affiliates
Operating expenses - affiliates remained unchanged for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019.
Depreciation and Amortization
The following table provide details of our depreciation and amortization expense:

| Three Months Ended March 31, |  | % Change
| 2020 |  | 2019 |
| (Dollars in millions) |  |
Depreciation | $ | 204 |  |  | 199 |  |  | 3 | %
Amortization | 124 |  |  | 137 |  |  | (9 | )%
Total depreciation and amortization | $ | 328 |  |  | 336 |  |  | (2 | )%

Depreciation expense is impacted by several factors, including changes in our depreciable cost basis, changes in our estimates of the remaining economic life of certain network assets and the addition of new plant. Depreciation expense increased by $5 million, or 3%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The increase in depreciation expense was primarily due to net growth in depreciable assets which was partially offset by the impact of annual rate depreciable life changes.
26

Table of Contents
Amortization expense decreased by $13 million, or 9%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease in amortization expense was primarily due to the effect of using an accelerated amortization method resulting in an incremental decline in expense as the intangible assets amortize.
Other Consolidated Results
The following table summarizes our total other (expense) income and income tax expense:

| Three Months Ended March 31, |  | % Change

_______________________________________________________________________________
nm - Percentages greater than 200% and comparisons between positive and negative values or to/from zero values are considered not meaningful.
Interest Expense
Interest expense decreased by $20 million, or 21%, for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease was primarily due to a decrease in average long-term debt and lower variable interest rates.
Interest Expense - Affiliates, Net
Affiliated interest expense remained unchanged for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019.
Other (Expense) Income, Net
Other income, net reflects certain items not directly related to our core operations, including interest income, gains and losses from non-operating asset dispositions and components of net periodic pension and post-retirement benefit costs. Other income, net decreased by $17 million for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019. The decrease in other income, net was primarily due to a loss on the retirement of debt and a reduction of interest income.
Income Tax Expense
Income tax expense for the three months ended March 31, 2020 was $177 million compared to $171 million for the three months ended March 31, 2019. Our effective tax rate was 26.0%, for both the three months ended March 31, 2020 and 2019.
Liquidity and Capital Resources
Overview of Sources and Uses of Cash
We are an indirectly wholly-owned subsidiary of CenturyLink. As such, factors relating to, or affecting, CenturyLink's liquidity and capital resources could have material impacts on us, including impacts on our credit ratings, our access to capital markets and changes in the financial market's perception of us.
27

Table of Contents
CenturyLink has cash management arrangements between certain of its subsidiaries that include lines of credit, affiliate advances and obligations, capital contributions and dividends. As part of these cash management arrangements, affiliates provide lines of credit to certain other affiliates. Amounts outstanding under these lines of credit and intercompany obligations vary from time to time. Under these arrangements, the majority of our cash balance is advanced on a daily basis for centralized management by CenturyLink's service company affiliate. From time to time we may declare and pay dividends to our stockholder, QSC, sometimes in excess of our earnings to the extent permitted by applicable law, using cash owed to us under these advances, which has the net effect of reducing the amount of these advances. Our debt covenants do not currently limit the amount of dividends we can pay to QSC. Given our cash management arrangement with our ultimate parent, CenturyLink, and the resulting amounts due to us from CenturyLink, a significant component of our liquidity is dependent upon CenturyLink's ability to repay its obligation to us.
We anticipate that our future liquidity needs will be met through (i) our cash provided by our operating activities, (ii) amounts due to us from CenturyLink, (iii) our ability to refinance QC's debt securities at maturity and (iv) capital contributions, advances or loans from CenturyLink or its affiliates if and to the extent they have available funds or access to available funds that they are willing and able to contribute, advance or loan.
Capital Expenditures
We incur capital expenditures on an ongoing basis in order to enhance and modernize our networks, compete effectively in our markets and expand and improve our service offerings. CenturyLink evaluates 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 the expected return on investment. The amount of CenturyLink’s consolidated capital investment is influenced by, among other things, demand for CenturyLink’s services and products, cash flow generated by operating activities, cash required for other purposes and regulatory considerations (such as CenturyLink's CAF II infrastructure buildout requirements). For more information on CenturyLink’s total capital expenditures, please see its annual and quarterly reports filed with the SEC.
For more information on our capital spending, see "Historical Information—Investing Activities" below and Item 1A of Part I of our annual report on Form 10-K for the year ended December 31, 2019 and Item 1A of Part II of this report.
Debt and Other Financing Arrangements
Subject to market conditions, and to the extent feasible, we expect to continue to issue debt securities, under Qwest Corporation, from time to time in the future primarily to refinance a substantial portion of our maturing debt. The availability, interest rate and other terms of any new borrowings will depend on the ratings assigned to Qwest Corporation by credit rating agencies, among other factors. We have no remaining debt maturities due in the next 12 months excluding finance lease obligations.
As of the date of this report, the credit ratings for Qwest Corporation's senior unsecured debt were as follows:

Agency | Credit Ratings
Standard & Poor's | BBB-
Moody's Investors Service, Inc. | Ba2
Fitch Ratings | BB+

CenturyLink, Inc.'s and Qwest Corporation's credit ratings are reviewed and adjusted from time to time by the rating agencies. For additional information regarding CenturyLink's and Qwest Corporation's funding arrangements, see "Risk Factors—Risk Related to CenturyLink's Recently-Completed Acquisition of Level 3" and "Risks Affecting Liquidity and Capital Resources" in Item 1A of Part I of our annual report on Form 10-K for the year ended December 31, 2019 and Item 1A of Part II of this report.

Term Loan
In 2015, we entered into a term loan in the amount of $100 million with CoBank, ACB. The outstanding unpaid principal amount of this term loan plus any accrued and unpaid interest is due on February 20, 2025. Interest is paid monthly based upon either the London Interbank Offered Rate (“LIBOR”) or the base rate (as defined in the credit agreement) plus an applicable margin between 1.50% to 2.50% per annum for LIBOR loans and 0.50% to 1.50% per annum for base rate loans depending on our then current senior unsecured long-term debt rating. At both March 31, 2020 and December 31, 2019, the outstanding principal balance on this term loan was $100 million.
Note Payable - Affiliate
On September 30, 2017, Qwest Corporation entered into an amended and restated revolving promissory note in the amount of $965 million with an affiliate of our ultimate parent company, CenturyLink, Inc. This note replaced and amended the original $1.0 billion revolving promissory note Qwest Corporation entered into on April 18, 2012 with the same affiliate. The outstanding principal balance owed by us under this revolving promissory note and the accrued interest thereon is due and payable on demand, but if no demand is made, then on June 30, 2022. Interest is accrued on the outstanding balance during an interest period using a weighted average per annum interest rate on the consolidated outstanding debt of CenturyLink and its subsidiaries. As of March 31, 2020, the weighted average interest rate was 5.561%. As of March 31, 2020 and December 31, 2019, the amended and restated revolving promissory note is reflected on our consolidated balance sheets as a current liability under note payable - affiliate. As of March 31, 2020, $15 million of accrued interest is reflected in other current liabilities on our consolidated balance sheets.
For additional information about our indebtedness, see Note 5—Long-Term Debt and Note Payable - Affiliate.
Dividends
We periodically pay dividends to our direct parent company. See Note 9—Dividends and the discussion above under the heading "Overview".
Pension and Post-retirement Benefit Obligations
CenturyLink is subject to material obligations under its existing defined benefit pension plans and post-retirement benefit plans. At December 31, 2019, the accounting unfunded status of CenturyLink's qualified and non-qualified defined benefit pension plans and qualified post-retirement benefit plans was approximately $1.8 billion and approximately $3.0 billion, respectively. For additional information about CenturyLink's pension and post-retirement benefit arrangements, see "Critical Accounting Policies and Estimates—Pensions and Post-Retirement Benefits" in Item 7 of CenturyLink's annual report on Form 10-K for the year ended December 31, 2019 and see Note 9—Employee Benefits to the consolidated financial statements in Item 8 of Part II of the same report.
A substantial portion of our active and retired employees participate in CenturyLink's qualified pension plan and post-retirement benefit plans. On December 31, 2014, the Qwest Communications International Inc. ("QCII") pension plan and a pension plan of an affiliate were merged into the CenturyLink Retirement Plan, which was renamed the CenturyLink Combined Pension Plan. Our contributions are not segregated or restricted to pay amounts due to our employees and may be used to provide benefits to other employees of our affiliates. Prior to the pension plan merger, the above-noted employees participated in the QCII pension plan.
Benefits paid by CenturyLink's qualified pension plan are paid through a trust that holds all of the plan's assets. Based on current laws and circumstances, CenturyLink does not expect any contributions to be required for their qualified pension plan during 2020. The amount of required contributions to CenturyLink's qualified pension plan in 2021 and beyond will depend on a variety of factors, most of which are beyond their control, including earnings on plan investments, prevailing interest rates, demographic experience, changes in plan benefits and changes in funding laws and regulations. CenturyLink occasionally makes voluntary contributions in addition to required contributions. CenturyLink does not currently expect to make a voluntary contribution to the trust for its qualified pension plan in 2020.

Substantially all of CenturyLink's post-retirement health care and life insurance benefits plans are unfunded. Several trusts hold assets that have been used to help cover the health care costs of certain retirees. As of December 31, 2019, assets in the post-retirement trusts had been substantially depleted and had a fair value of $13 million (a portion of which was comprised of investments with restricted liquidity), which has significantly limited CenturyLink's ability to continue paying benefits from the trusts; however, CenturyLink will continue to pay certain benefits through the trusts. Benefits not paid from the trusts are expected to be paid directly by CenturyLink with available cash.
The affiliate obligations, net in current and noncurrent liabilities on our consolidated balance sheets primarily represents the cumulative allocation of expenses, net of payments, associated with QCII's pension plans and post-retirement benefits plans prior to the plan mergers. In 2015, we agreed to a plan to settle the outstanding pension and post-retirement affiliate obligations, net balance with QCII over a 30 year term. Under the plan, payments are scheduled to be made on a monthly basis. For the three months ended March 31, 2020, we made settlement payments of $18 million to QCII in accordance with the plan. Changes in the affiliate obligations, net are reflected in operating activities on our consolidated statements of cash flows. For 2020, we expect to make aggregate settlement payments of $72 million to QCII under the plan.
The capital markets have been volatile during 2020, partially as a result of the COVID-19 outbreak. 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 2020, CenturyLink's estimated annual long-term rates of return, net of administrative costs, are 6% and 4% for the pension plan trust assets and post-retirement plans' trust assets, respectively, based on the assets currently held. However, actual returns could be substantially different.
For additional information, see “Risk Factors—Risks Affecting Our Liquidity and Capital Resources—Adverse changes in the value of assets or obligations associated with CenturyLink’s qualified pension plan could negatively impact CenturyLink’s liquidity, which may in turn affect our business and liquidity” in Item 1A of Part I of our annual report on Form 10-K for the year ended December 31, 2019 and Item 1A of Part II of this report.
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, 2019.
Connect America Fund
As a result of accepting CAF II support payments, we must meet certain specified infrastructure buildout requirements in 13 states over the next several years. In order to meet these specified infrastructure buildout requirements, we may be obligated to make substantial capital expenditures. Due to governmental restrictions and potential supply delays related to the COVID-19 pandemic, we cannot provide any assurances that we will be able to timely meet our mandated buildout requirements.
On January 30, 2020, the FCC approved an order creating the Rural Digital Opportunity Fund (the “RDOF”) which is a new federal support program designed to follow the CAF Phase II program. Through the RDOF, the FCC
plans to award up to $20.4 billion in support payments over 10 years to bring broadband to unserved areas through
multi-round reverse auctions conducted in two phases, the first of which is scheduled for October 2020. For CAF
Phase II participants like our ultimate parent, CenturyLink, support payments awarded in the initial phase of RDOF would begin January 1, 2022. Qwest Corporation and CenturyLink are currently analyzing the opportunity to participate in the initial RDOF auction. In its January order, the FCC also clarified that CAF II recipients, like CenturyLink, would receive an additional year of CAF Phase II funding in 2021. We cannot assure you that the final terms of the RDOF will match those described above.
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, 2019, (ii) "Risk Factors—Risks Affecting our Liquidity and Capital Resources" in Item 1A of Part I of our annual report on Form 10-K for the year ended December 31, 2019 and (iii) Item 1A Part II of this report.

Historical Information
The following table summarizes our consolidated cash flow activities:

| Three Months Ended March 31, |  | Change
| 2020 |  | 2019 |
| (Dollars in millions)
Net cash provided by operating activities | $ | 785 |  |  | 732 |  |  | 53 |
Net cash provided by (used in) investing activities | 830 |  |  | (375 | ) |  | 1,205 |
Net cash used in financing activities | (1,609 | ) |  | (353 | ) |  | 1,256 |

Operating Activities
Net cash provided by operating activities increased by $53 million for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019 primarily due to increased cash flows from accounts receivable and increased accrued income and other tax accruals partially offset by cash used for prepaid expenses and reductions of other current liabilities. Cash provided by operating activities is subject to variability period over period as a result of timing of the collection of receivables and payments related to interest expense, accounts payable and bonuses.
Investing Activities
Net cash provided by investing activities increased by $1.2 billion for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019 primarily due to funds received from advances to affiliates.
Financing Activities
Net cash used in financing activities increased by $1.3 billion for the three months ended March 31, 2020 as compared to the three months ended March 31, 2019 primarily due to repayments of long-term debt.
See Note 5—Long-Term Debt and Note Payable - Affiliate, for additional information on our outstanding debt securities and financing activities.
Other Matters
We are subject to various legal proceedings and other contingent liabilities that individually or in the aggregate could materially affect our financial condition, future results of operations or cash flows. See Note 8—Commitments, Contingencies and Other Items for additional information.
CenturyLink is involved in several legal proceedings to which we are not a party that, if resolved against it, could have a material adverse effect on its business and financial condition. As a wholly owned subsidiary of CenturyLink, our business and financial condition could be similarly affected. You can find descriptions of these legal proceedings in CenturyLink's quarterly and annual reports filed with the SEC. Because we are not a party to any of the matters, we have not accrued any liabilities for these matters.
Market Risk
As of March 31, 2020, we were exposed to market risk from changes in interest rates on our variable rate long-term debt obligations, amended and restated revolving promissory note 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) lock-in or swap our exposure to changing or variable interest rates for fixed interest rates or (ii) to swap obligations to pay fixed interest rates for variable interest rates. As of March 31, 2020, we had no such instruments outstanding nor held or issued derivative financial instruments for trading or speculative purposes.

Table of Contents
We do not believe that there were any material changes to market risks arising from changes in interest rates for the three months ended March 31, 2020, when compared to the disclosures provided in our annual report on Form 10-K for the year ended December 31, 2019.
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, 2020.
Off-Balance Sheet Arrangements
As of March 31, 2020, we had no special purpose or limited purpose entities that provide off-balance sheet financing, liquidity, or market or credit risk support, and we did not engage in leasing, hedging or other similar activities that expose us to any significant liabilities that are not (i) reflected on the face of the consolidated financial statements, (ii) disclosed in Note 16—Commitments, Contingencies and Other Items to our consolidated financial statements in Item 8 of Part II of our annual report on Form 10-K for the year ended December 31, 2019, or in the Future Contractual Obligations table included in Item 7 of Part II of the same report, or (iii) discussed under the heading "Market Risk" above.

Omitted pursuant to General Instruction H(2).
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 the Company in the reports that it files or furnishes 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 that this information is accumulated and communicated to the Company’s management, including its 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 the Company’s disclosure controls and procedures as of March 31, 2020. Based on this evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective, as of March 31, 2020, in providing reasonable assurance that 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 the Company’s 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 2020 that have materially affected, or are reasonably likely to materially affect, the Company’s 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.

PART II—OTHER INFORMATION
ITEM 1. LEGAL PROCEEDINGS
The information contained in Note 8—Commitments, Contingencies and Other Items included in Item 1 of Part I of this report is incorporated herein by reference. The ultimate outcome of the matters described in Note 8 may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our statements appearing in such Note, and proceedings currently viewed as immaterial by us may ultimately materially impact us. For more information, see “Risk Factors—Risks Relating to Legal and Regulatory Matters—Our pending legal proceedings could have a material adverse impact on our financial condition and operating results, on the trading price of our securities and on our ability to access the capital markets” in Item 1A of Part I of our annual report on Form 10-K for the year ended December 31, 2019 and Item 1A of Part II of this report.
ITEM 1A. RISK FACTORS
Our operations and financial results are subject to various risks and uncertainties, which could adversely affect our business, financial condition or future results. We urge you to carefully consider (i) the other information set forth in this report and (ii) the risk factors discussed in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019, as supplemented by the additional risk factors appearing below:
An outbreak of disease or similar public health threat, such as the recent COVID‑19 pandemic, could have a material adverse impact on our operating results and financial condition
An outbreak of disease or similar public health threat, such as the recent COVID‑19 pandemic and its detrimental impact on the worldwide economy, could have a material adverse impact on our operating results and financial condition.
We are vulnerable to the general economic effects of disease outbreaks and similar public health threats. Since the latter half of the first quarter of 2020, the COVID-19 pandemic has caused a sudden and substantial reduction in worldwide economic activity. COVID-19 poses the risk that we or our employees, contractors, suppliers, customers and other business partners may be prevented from conducting business activities at expected levels through established processes for an indefinite period of time, including due to shutdowns or related restrictions that may be requested or mandated by governmental authorities. We provide services in regions significantly impacted by COVID-19. The extent to which COVID-19 will ultimately impact our results, including its impact on demand for our products and services and related impacts upon network usage, the ability of our customers to continue to pay in a timely manner, the impact on other third parties upon which our operations, financial performance and liquidity are materially reliant, impacts on our relationships with unionized employees and related collective bargaining agreements negotiations, impacts upon counterparty risk relative to our major contracts, impacts upon our transformational efforts and impacts on our supply chains or distribution channels for our products and service, is dependent on future developments, which are uncertain and unpredictable, including new information which may emerge concerning the risks and severity of COVID-19 and additional actions which may be taken to contain it or treat its impact. Such future uncertain and unpredictable developments include:

• | The duration, extent and severity of the pandemic. COVID-19 has rapidly spread worldwide, and it is not yet known (i) when the current pandemic will abate, (ii) whether, when or to what extent additional outbreaks may arise, (iii) the extent to which various populations will experience more severe adverse health consequences, (iv) the effectiveness of current mitigation steps, and (v) whether or when treatments or vaccines will be developed to ameliorate or staunch the pandemic.

• | The response of governmental and nongovernmental authorities. Many governmental and nongovernmental bodies have taken action to substantially curtail household and business activity to help slow the spread of COVID-19 or to otherwise mitigate its potential adverse effects. In the United States and many other countries, these mandates have been issued by state or local officials, which significantly increases the unpredictability and variability of when and how these mandates will be amended or rescinded. The significant health and economic challenges arising out of the pandemic has led to changes in laws governing the rights of workers and has caused, and may continue to cause, various parties to propose additional changes to laws or regulations, including those governing communications companies. The continuing impact of existing or new mandates, restrictions, laws or regulations could have a material adverse impact on our operations and the operations of our suppliers or others with which we do business.

• | Impacts to economic and market conditions. COVID-19 has created significant disruption to and volatility in global, national, regional and local economies and markets. Uncertainties related to, and perceived or experienced negative effects from, COVID-19 may cause significant volatility or decline in the trading price of our securities, worldwide labor markets and general economic conditions. These changes began to affect us, our customers and our business by the end of the first quarter of 2020. Following the first quarter of 2020, we expect these changes either may or will (i) increase the likelihood of litigation, including derivative shareholder litigation, (ii) continue to limit or restrict our ability to conduct normal business activities with customers, vendors, lenders or others with whom we do business, (iii) continue to result in changes in spending patterns or reduced demand for our products and services, (iv) result in reductions in our labor force, (v) cause us to delay or change our operating, capital spending or transformational plans, (vi) result in future changes in tax rates, (vii) restrict our ability to implement our transformation plans and (viii) otherwise render it more difficult or impossible to implement our operational or strategic plans.

• | Impacts to Capital Markets. Shortly after COVID-19 began its rapid spread beyond Asia, domestic and worldwide capital markets ceased operating for a short period, and have remained unstable or unpredictable since then, particularly for non-investment grade issuers. Legislative bodies and reserve banks have taken various actions in response to the pandemic that have impacted the capital markets, and we expect that these efforts could continue. We and our affiliates are materially reliant upon the capital markets to access funding necessary to refinance our outstanding indebtedness. If the economic disruptions caused by COVID-19 continues to interfere with the operations of the capital markets, our access to cash to refinance our debt or to fund our other cash requirements could be materially adversely affected.

• | Impacts to individuals and companies that may do business with us or be involved in our business. COVID-19 may impact the health of our employees, directors or customers, reduce the availability of our workforce or those of companies with which we do business, create disruptions in our supply chain or otherwise cause human impacts that have a material adverse impact on our business.

In addition, preparing for and responding to the continuing pandemic could divert management’s attention from our key strategic priorities, increase costs as we prioritize health and safety matters for our employees and customers, cause us to reduce, delay, alter or abandon initiatives that may otherwise increase our long-term value, increase vulnerability to information technology or cybersecurity related risks as more of our employees work remotely and otherwise continue to disrupt our business operations. Moreover, if the pandemic ultimately materially reduces our cash flows, we may need to re-evaluate our capital allocation plans, especially if increased broadband usage increases our need to invest in our network to remain competitive.
While it is not possible at this time to estimate the full impact that COVID-19 could have on our business, the continued spread of COVID-19 and the measures taken by governments to combat it are expected to impact us to a greater degree in the second quarter of 2020 and could have a material adverse impact on our operating results and financial condition.
Moreover, to the extent any of these risks and uncertainties adversely impact us in the ways described above or otherwise, they may also have the effect of heightening many of the other risks described under the section entitled “Item 1A. Risk Factors” in our annual report on Form 10‑K for the year ended December 31, 2019, including those relating to the risks of regulatory noncompliance and additional asset impairments. Specifically, pandemic-related constraints could preclude us from meeting our broadband buildout commitments under the FCC's CAF program. In addition, during the first quarter of 2020, CenturyLink observed a decline in its stock price as a result of events occurring after the end of 2019, including the COVID-19 pandemic. We evaluated whether such events would indicate the fair value of our reporting unit was below its carrying value. We believe these events have impacted the global economy more directly than us, and when considered with other factors, we have concluded that it is not more likely than not that the fair value of our reporting unit was less than its carrying value as of the quarter ended March 31, 2020. In light of the negative impacts of COVID-19 on the global economy, we will continue to evaluate the general economic trends which could have an impact on our assessment of whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. Future changes could cause our reporting unit fair value to be less than its carrying value, resulting in potential impairments of our goodwill which could have a material effect on our results of operations and financial condition. The extent of the impact, if any, will depend on future developments including actions taken to contain the coronavirus and its long-term impacts on the overall economy.

We have taken certain precautions due to the uncertain and evolving situation relating to the spread of COVID-19 that could have a material adverse impact our operating results and financial condition
In light of the uncertain and evolving situation relating to the spread of COVID-19, we have taken temporary precautionary measures intended to help minimize the risk of the virus to our employees, our customers, business partners and the communities in which we participate, which could have a material adverse impact on our operating results and financial condition. To this end, we have, among other things, established safety protocols for the safety of our on-site technicians and customers, adopted an employee work-from-home policy where employees who can work-from-home do so, substantially restricted non-essential business travel and CenturyLink has taken the “Keep Americans Connected Pledge,” which obligates us in certain circumstances to waive late fees and to not terminate a residential or small business customer’s service due to financial circumstances associated with COVID-19 for a period of time. In addition to reducing our late fee revenues, these measures could make it more difficult to (i) timely and efficiently furnish products and services to our customers, (ii) devote sufficient resources to our ongoing network and product simplification projects, (iii) efficiently monitor and maintain our network, (iv) maintain effective internal controls (v) mitigate information technology or cybersecurity related risks and (vi) otherwise operate and administer our affairs. As such, these measures ultimately could have a material adverse impact on our operating results and financial condition. The extent to which COVID-19 may impact our workforce, business, financial condition and results of operations will depend on future developments, which are highly uncertain and cannot be predicted with a reasonable level of certainty at this time.
