NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Dollars in millions except per share amounts

NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS

Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications, media and technology industries. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2019. The results for the interim periods are not necessarily indicative of those for the full year. These consolidated financial statements include all adjustments that are necessary to present fairly the results for the presented interim periods, consisting of normal recurring accruals and other items.

All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included for periods ended within up to one quarter of our period end. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including potential impacts arising from the COVID-19 pandemic, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation.

In the tables throughout this document, percentage increases and decreases that are not considered meaningful are denoted with a dash.

Adopted and Pending Accounting Standards and Other Changes

Credit Losses As of January 1, 2020, we adopted, through modified retrospective application, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13, as amended), which replaces the incurred loss impairment methodology under prior GAAP with an expected credit loss model. ASU 2016-13 affects trade receivables, loans, contract assets, certain beneficial interests, off-balance-sheet credit exposures not accounted for as insurance and other financial assets that are not subject to fair value through net income, as defined by the standard. Under the expected credit loss model, we are required to consider future economic trends to estimate expected credit losses over the lifetime of the asset. Upon adoption, we recorded a $293 reduction to “Retained earnings,” $395 increase to “allowances for doubtful accounts” applicable to our trade and loan receivables, $10 reduction of contract assets, $105 reduction of net deferred income tax liability and $7 reduction of “Noncontrolling interest” as an opening adjustment. Our adoption of ASU 2016-13 did not have a material impact on our financial statements.

Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), which provides optional expedients, and allows for certain exceptions to existing GAAP, for contract modifications triggered by the expected market transition of certain benchmark interest rates to alternative reference rates. ASU 2020-04 applies to contracts, hedging relationships and other arrangements that reference the London Interbank Offering Rate (LIBOR) or any other rates ending after December 31, 2022. We are evaluating the impact of our adoption of ASU 2020-04, including optional expedients, for impact to our financial statements.

Intangible Assets During the first quarter of 2020, in conjunction with the nationwide launch of AT&T TV and our customers’ continued shift from linear to streaming video services, we reassessed the estimated economic lives and renewal assumptions for our orbital slot licenses. As a result, we have changed the estimated lives of these licenses from indefinite to finite-lived, effective January 1, 2020, and began amortizing our orbital slot licenses using the sum-of-months-digits method over their average remaining economic life of 15 years. This change in accounting increased amortization expense $386, or $0.04 per diluted share available to common stock during the first quarter of 2020.

We also reassessed and changed the estimated economic lives of certain trade names in our Latin America business from indefinite to finite-lived and began amortizing them using the straight-line method over their average remaining economic life of 15 years. This change had an insignificant impact on our financial statements.

NOTE 4. SEGMENT INFORMATION

Our segments are strategic business units that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We analyze our segments based on segment operating contribution, which consists of operating income, excluding acquisition-related costs and other significant items (as discussed below), and equity in net income (loss) of affiliates for investments managed within each segment. We have four reportable segments: (1) Communications, (2) WarnerMedia, (3) Latin America, and (4) Xandr.

We also evaluate segment and business unit performance based on EBITDA and/or EBITDA margin, which is defined as operating contribution excluding equity in net income (loss) of affiliates and depreciation and amortization. We believe EBITDA to be a relevant and useful measurement to our investors as it is part of our internal management reporting and planning processes and it is an important metric that management uses to evaluate operating performance. EBITDA does not

give effect to cash used for debt service requirements and thus does not reflect available funds for distributions, reinvestment or other discretionary uses. EBITDA margin is EBITDA divided by total revenues.

The Communications segment provides wireless and wireline telecom, video and broadband services to consumers located in the U.S. and businesses globally. This segment contains the following business units:

Mobility provides nationwide wireless service and equipment.

Entertainment Group provides video, including over-the-top (OTT) services, broadband and voice communications services primarily to residential customers. This segment also sells advertising on distribution platforms.

Business Wireline provides advanced IP-based services, as well as traditional voice and data services to business customers.

The WarnerMedia segment develops, produces and distributes feature films, television, gaming and other content in various physical and digital formats globally. This segment contains the following business units:

Turner primarily operates multichannel basic television networks and digital properties. Turner also sells advertising on its networks and digital properties.

Home Box Office consists of premium pay television and OTT and streaming services domestically and premium pay, basic tier television and OTT services internationally, as well as content licensing and home entertainment.

Warner Bros. primarily consists of the production, distribution and licensing of television programming and feature films, the distribution of home entertainment products and the production and distribution of games.

The Latin America segment provides entertainment and wireless services outside of the U.S. This segment contains the following business units:

Vrio provides video services primarily to residential customers using satellite technology in Latin America and the Caribbean.

Mexico provides wireless service and equipment to customers in Mexico.

The Xandr segment provides advertising services. These services utilize data insights to develop and deliver targeted advertising across video and digital platforms. Certain revenues in this segment are also reported by the Communications segment and are eliminated upon consolidation.

Corporate and Other reconciles our segment results to consolidated operating income and income before income taxes, and includes:

Corporate, which consists of: (1) businesses no longer integral to our operations or which we no longer actively market, (2) corporate support functions, (3) impacts of corporate-wide decisions for which the individual operating segments are not being evaluated and (4) the reclassification of the amortization of prior service credits, which we continue to report with segment operating expenses, to consolidated “Other income (expense) – net.”

Acquisition-related items which consists of items associated with the merger and integration of acquired businesses, including amortization of intangible assets.

Certain significant items includes (1) employee separation charges associated with voluntary and/or strategic offers, (2) losses resulting from abandonment or impairment of assets and (3) other items for which the segments are not being evaluated.

Eliminations and consolidations, which (1) removes transactions involving dealings between our segments, including content licensing between WarnerMedia and Communications, and (2) includes adjustments for our reporting of the advertising business.

“Interest expense” and “Other income (expense) – net,” are managed only on a total company basis and are, accordingly, reflected only in consolidated results.

Deferred Customer Contract Acquisition and Fulfillment Costs

Costs to acquire and fulfill customer contracts, including commissions on service activations, for our wireless, business wireline and video entertainment services, are deferred and amortized over the contract period or expected customer relationship life, which typically ranges from three years to five years. For contracts with an estimated amortization period of less than one year, we expense incremental costs immediately.

The following table presents the deferred customer contract acquisition costs and deferred customer contract fulfillment costs included on our consolidated balance sheets:

		March 31,		December 31,
Consolidated Balance Sheets		2020		2019
Deferred Acquisition Costs

Consolidated Statements of Income		2020		2019
Deferred acquisition cost amortization	$	636	$	547
Deferred fulfillment cost amortization		1,305		1,098

Contract Assets and Liabilities

A contract asset is recorded when revenue is recognized in advance of our right to bill and receive consideration. The contract asset will decrease as services are provided and billed. For example, when installment sales include promotional discounts (e.g., “buy one get one free”) the difference between revenue recognized and consideration received is recorded as a contract asset to be amortized over the contract term.

When consideration is received in advance of the delivery of goods or services, a contract liability is recorded for deferred revenue. Reductions in the contract liability will be recorded as we satisfy the performance obligations.

The following table presents contract assets and liabilities on our consolidated balance sheets:

		March 31,		December 31,
		2020		2019
Contract asset	$	2,598	$	2,472
Contract liability		6,757		6,999

Our beginning of period contract liability recorded as customer contract revenue during 2020 was $4,519.

Dollars in millions except per share amounts

Our consolidated balance sheets at March 31, 2020 and December 31, 2019 included approximately $1,700 and $1,611, respectively, for the current portion of our contract asset in “Other current assets” and $5,769 and $5,939, respectively, for the current portion of our contract liability in “Advanced billings and customer deposits.”

Remaining Performance Obligations

Remaining performance obligations represent services we are required to provide to customers under bundled or discounted arrangements, which are satisfied as services are provided over the contract term. In determining the transaction price allocated, we do not include non-recurring charges and estimates for usage, nor do we consider arrangements with an original expected duration of less than one year, which are primarily prepaid wireless, video and residential internet agreements.

Remaining performance obligations associated with business contracts reflect recurring charges billed, adjusted to reflect estimates for sales incentives and revenue adjustments. Performance obligations associated with wireless contracts are estimated using a portfolio approach in which we review all relevant promotional activities, calculating the remaining performance obligation using the average service component for the portfolio and the average device price. As of March 31, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $36,486, of which we expect to recognize approximately 86% by the end of 2021, with the balance recognized thereafter.

NOTE 6. PENSION AND POSTRETIREMENT BENEFITS

Many of our employees are covered by one of our noncontributory pension plans. We also provide certain medical, dental, life insurance and death benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs. Our objective in funding these plans, in combination with the standards of the Employee Retirement Income Security Act of 1974, as amended (ERISA), is to accumulate assets sufficient to provide benefits described in the plans to employees upon their retirement. We do not have significant funding requirements in 2020.

We recognize actuarial gains and losses on pension and postretirement plan assets in our consolidated results as a component of “Other income (expense) – net” at our annual measurement date of December 31, unless earlier remeasurements are required.

NOTE 7. FAIR VALUE MEASUREMENTS AND DISCLOSURE

The Fair Value Measurement and Disclosure framework in ASC 820, “Fair Value Measurement,” provides a three-tiered fair value hierarchy based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs.

The level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs.

The valuation methodologies described above may produce a fair value calculation that may not be indicative of future net realizable value or reflective of future fair values. We believe our valuation methods are appropriate and consistent with other market participants. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies used since December 31, 2019.

Investment Securities

Our investment securities include both equity and debt securities that are measured at fair value, as well as equity securities without readily determinable fair values. A substantial portion of the fair values of our investment securities is estimated based on quoted market prices. Investments in equity securities not traded on a national securities exchange are valued at cost, less any impairment, and adjusted for changes resulting from observable, orderly transactions for identical or similar securities. Investments in debt securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows.

The components comprising total gains and losses in the period on equity securities are as follows:

	Three months ended
	March 31,
	2020		2019
Total gains (losses) recognized on equity securities	$	(203)	$	160
Gains (losses) recognized on equity securities sold		(33)		18
Unrealized gains (losses) recognized on equity securities held at end of period		(170)		142

At March 31, 2020, available-for-sale debt securities totaling $1,514 have maturities as follows - less than one year: $78; one to three years: $149; three to five years: $160; for five or more years: $1,127.

Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and nonrefundable customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments and nonrefundable customer deposits are recorded in “Other current assets” and our investment securities are recorded in “Other Assets” on the consolidated balance sheets.

Derivative Financial Instruments

We enter into derivative transactions to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged.

Fair Value Hedging We designate our fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount.

We also designate some of our foreign exchange contracts as fair value hedges. The purpose of these contracts is to hedge currency risk associated with foreign-currency-denominated operating assets and liabilities.

Accrued and realized gains or losses from fair value hedges impact the same category on the consolidated statements of income as the item being hedged. Unrealized gains on fair value hedges are recorded at fair market value as assets, and unrealized losses are recorded at fair market value as liabilities. Changes in the fair value of derivative instruments designated as fair value hedges are offset against the change in fair value of the hedged assets or liabilities through earnings. In the three months ended March 31, 2020 and 2019, no ineffectiveness was measured on fair value hedges.

Cash Flow Hedging We designate our cross-currency swaps as cash flow hedges. We have entered into multiple cross-currency swaps to hedge our exposure to variability in expected future cash flows that are attributable to foreign currency risk generated from the issuance of our foreign-denominated debt. These agreements include initial and final exchanges of principal from fixed foreign currency denominated amounts to fixed U.S. dollar denominated amounts, to be exchanged at a specified rate that is usually determined by the market spot rate upon issuance. They also include an interest rate swap of a fixed or floating foreign currency-denominated interest rate to a fixed U.S. dollar denominated interest rate.

We also designate some of our foreign exchange contracts as cash flow hedges. The purpose of these contracts is to hedge certain film production costs denominated in foreign currencies.

Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, changes in fair value are reported as a component of accumulated OCI and are reclassified into the consolidated statements of income in the same period the hedged transaction affects earnings.

Periodically, we enter into and designate interest rate locks to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We designate our interest rate locks as cash flow hedges. Gains and losses when we settle our interest rate locks are amortized into income over the life of the related debt. Over the next 12 months, we expect to reclassify $60 from accumulated OCI to “Interest expense” due to the amortization of net losses on historical interest rate locks.

Net Investment Hedging We have designated €1,364 million aggregate principal amount of debt as a hedge of the variability of some of the Euro-denominated net investments of our subsidiaries. The gain or loss on the debt that is designated as, and is effective as, an economic hedge of the net investment in a foreign operation is recorded as a currency translation adjustment within accumulated OCI, net on the consolidated balance sheet. Net gains on net investment hedges recognized in accumulated OCI for 2020 were $25.

Collateral and Credit-Risk Contingency We have entered into agreements with our derivative counterparties establishing collateral thresholds based on respective credit ratings and netting agreements. At March 31, 2020, we had posted collateral of $2,809 (a deposit asset) and held no collateral. Under the agreements, if AT&T’s credit rating had been downgraded one rating level by Fitch Ratings before the end of March, we would not have been required to post any additional collateral. If AT&T’s credit rating had been downgraded four rating levels by Fitch Ratings, two levels by S&P, and two levels by Moody’s, we would have been required to post additional collateral of $6,149. If DIRECTV Holdings LLC’s credit rating had been downgraded below BBB- (S&P), we would have been required to post additional collateral of $200. At December 31, 2019, we had posted collateral of $204 (a deposit asset) and held collateral of $44 (a receipt liability). We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) exists, against the fair value of the derivative instruments.

NOTE 8. SALES OF RECEIVABLES

We have agreements with various third-party financial institutions pertaining to the sales of certain types of our accounts receivable. The most significant of these programs are discussed in detail below and generally consist of (1) receivables arising from equipment installment plans, which are sold for cash and a deferred purchase price, and (2) revolving service and trade receivables. Under these programs, we transfer receivables to purchasers in exchange for cash and additional consideration upon settlement of the receivables, where applicable. Under the terms of our agreements for these programs, we continue to bill and collect the payments from our customers on behalf of the financial institutions.

The sales of receivables did not have a material impact on our consolidated statements of income or to “Total Assets” reported on our consolidated balance sheets. We reflect cash receipts on sold receivables as cash flows from operations in our

consolidated statements of cash flows. Cash receipts on the deferred purchase price are classified as cash flows from investing activities.

Our equipment installment and revolving receivable programs are discussed in detail below. The following table sets forth a summary of the receivables and accounts being serviced:

Equipment Installment Receivables Program

We offer our customers the option to purchase certain wireless devices in installments over a specified period of time and, in many cases, once certain conditions are met, they may be eligible to trade in the original equipment for a new device and have the remaining unpaid balance paid or settled.

We maintain a program under which we transfer a portion of these receivables through our bankruptcy-remote subsidiary in exchange for cash and additional consideration upon settlement of the receivables, referred to as the deferred purchase price. In the event a customer trades in a device prior to the end of the installment contract period, we agree to make a payment to the financial institutions equal to any outstanding remaining installment receivable balance. Accordingly, we record a guarantee obligation for this estimated amount at the time the receivables are transferred.

The following table sets forth a summary of equipment installment receivables sold under this program during the three months ended March 31, 2020 and 2019:

		Three months ended March 31,
			2020		2019
Gross receivables sold		$	2,367	$	2,701

Deferred purchase price recorded			353		309
Guarantee obligation recorded			44		101
1	Receivables net of allowance, imputed interest and equipment trade-in right guarantees.

The deferred purchase price and guarantee obligation are initially recorded at estimated fair value and subsequently adjusted for changes in present value of expected cash flows. The estimation of their fair values is based on remaining installment payments expected to be collected and the expected timing and value of device trade-ins. The estimated value of the device trade-ins considers prices offered to us by independent third parties that contemplate changes in value after the launch of a

device model. The fair value measurements used for the deferred purchase price and the guarantee obligation are considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7).

The following table presents the previously transferred equipment installment receivables, which we repurchased in exchange for the associated deferred purchase price during the three months ended March 31, 2020 and 2019:

		Three months ended March 31,
			2020		2019
Fair value of repurchased receivables		$	288	$	423
Carrying value of deferred purchase price			277		407
Gain on repurchases1		$	11	$	16
1	These gains are included in “Selling, general and administrative” in the consolidated statements of income.

At March 31, 2020 and December 31, 2019, our deferred purchase price receivable was $2,378 and $2,336, respectively, of which $1,583 and $1,569 are included in “Other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at March 31, 2020 and December 31, 2019 was $351 and $384, respectively, of which $189 and $148 are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets, with the remainder in “Other noncurrent liabilities.” Our maximum exposure to loss as a result of selling these equipment installment receivables is limited to the total amount of our deferred purchase price and guarantee obligation.

Revolving Receivables Program

In 2019, we entered into a revolving agreement to transfer up to $4,300 of certain receivables through our bankruptcy-remote subsidiaries to various financial institutions on a recurring basis in exchange for cash equal to the gross receivables transferred. In the first quarter of 2020, we expanded the program limit to $5,300. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts (e.g., collect and reinvest). The transferred receivables are fully guaranteed by our bankruptcy-remote subsidiaries, which hold additional receivables in the amount of $4,057 that are pledged as collateral under this agreement. The transfers are recorded at fair value of the proceeds received and obligations assumed less derecognized receivables. The obligation is subsequently adjusted for changes in estimated expected credit losses. Our maximum exposure to loss related to these receivables transferred is limited to the amount outstanding.

The fair value measurement used for the obligation is considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7).

The following table sets forth a summary of receivables sold:

			Three months ended March 31,
			2020		2019

NOTE 9. LEASES

We have operating and finance leases for certain facilities and equipment used in operations. Our leases generally have remaining lease terms of up to 15 years. Some of our real estate operating leases contain renewal options that may be exercised, and some of our leases include options to terminate the leases within one year.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - Continued

Dollars in millions except per share amounts

We have recognized a right-of-use asset for both operating and finance leases, and an operating lease liability that represents the present value of our obligation to make payments over the lease term. The present value of the lease payments is calculated using the incremental borrowing rate for operating and finance leases, which was determined using a portfolio approach based on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate in the currency of the lease, which will be updated on a quarterly basis for measurement of new lease liabilities.

The components of lease expense were as follows:

	Three months ended March 31,
	2020		2019

COVID-19 UPDATE

In March 2020, the World Health Organization designated the coronavirus (COVID-19) a pandemic and the President of the United States declared a national emergency. To date, COVID-19 has surfaced in nearly all regions around the world and resulted in travel restrictions and business slowdowns or shutdowns.

Disruptions caused by COVID-19 and measures taken to prevent its spread or mitigate its effects both domestically and internationally have impacted our results of operations. In the first quarter of 2020, we recognized approximately $430, or $0.05 per share, of incremental costs associated with bad debt reserves, voluntary corporate actions taken primarily to protect and compensate front-line employees and contractors, and WarnerMedia production shutdown costs. We expect more than half of these incremental charges will be short-term in nature.

In addition to these incremental costs, our operations and comparability were impacted by (1) the cancellation of the NCAA Division I Men’s Basketball Tournament (NCAA tournament), resulting in lower advertising revenues and associated expenses, (2) closures of retail stores, contributing to a decline in wireless equipment sales, with a corresponding reduction in equipment expense and (3) the imposition of travel restrictions, driving significantly lower wireless roaming services that do not have a directly correlated expense reduction. The net impact of these items on profitability was not significant.

All subscriber counts at and for the period ended March 31, 2020, exclude customers who we have agreed not to terminate service under the Federal Communications Commission (FCC) “Keep Americans Connected Pledge.” For reporting purposes, we count these subscribers as if they had disconnected service.

The economic effects of the pandemic and resulting societal changes are currently not predictable. We expect that COVID-19 could affect additional areas of our business in future quarters and that the financial impacts could vary from those seen in the first quarter. There are a number of uncertainties that could impact our future results of operations, including the effectiveness of COVID-19 mitigation measures; the duration of the pandemic; global economic conditions; changes to our operations; changes in consumer confidence, behaviors and spending; work from home trends; and the sustainability of supply chains.

Due to the uncertainty of the COVID-19 pandemic and recovery, we have withdrawn our prior financial guidance.

Operating revenues decreased in the first quarter of 2020. The decrease was driven by declines in our WarnerMedia, Communications and Latin America segments. Lower WarnerMedia segment revenues reflect unfavorable programming comparisons, including strong carryover theatrical revenues in the first quarter of 2019, and lower advertising revenues from the cancellation of the NCAA tournament. Communications segment revenue declines were driven by continued declines in video and legacy services and lower wireless equipment sales resulting from store closures. Latin America segment revenue declines were primarily due to foreign exchange pressure. Partially offsetting these decreases were revenue increases in wireless service and strategic and managed business service in our Communications segment.

Operations and support expenses decreased in the first quarter of 2020. The decrease was driven by a noncash gain of $900 on a spectrum transaction, lower broadcast and programming costs in our Communications and WarnerMedia segments, reduced wireless equipment costs resulting from lower device sales and lower sports licenses from the cancellation of televised sporting events. Expense declines also reflect our continued focus on cost management. Partially offsetting the decreases were incremental costs, including bad debt, associated with COVID-19. As part of our cost and efficiency initiatives, we expect operations and support expense improvements to continue as we size our operations to reflect the new economic activity level.

Depreciation and amortization expense increased in the first quarter of 2020.

Depreciation expense increased $29, or 0.6%, primarily due to ongoing capital spend for network upgrades and expansion in our Communications segment.

Amortization expense decreased $13, or 0.6%, primarily due to the decreased amortization of intangibles associated with WarnerMedia, largely offset by commencement of amortization for orbital slot licenses, beginning in the first quarter of 2020 (see Note 1).

Operating income increased in the first quarter of 2020. Our operating income margin in the first quarter increased from 16.1% in 2019 to 17.5% in 2020.

Interest expense decreased in the first quarter of 2020, primarily due to lower debt balances.

Equity in net income (loss) of affiliates was essentially flat in the first quarter of 2020, reflecting changes in our investment portfolio, including the second-quarter 2019 sale of Hulu.

Other income (expense) – net increased in the first quarter of 2020 primarily due to an increase in net benefit credit resulting from lower interest costs on the benefit obligation and higher prior service credit amortization in 2020 and an actuarial loss on pension benefits in 2019 (see Note 6). Partially offsetting the increase were losses on investments in equity securities resulting from market declines in the first quarter of 2020.

Income taxes increased in the first quarter of 2020. Our effective tax rate was 20.8% for the first quarter of 2020, versus 19.0% for the comparable year prior. The increase in income tax expense was primarily due to higher income before income taxes and the impacts of tax settlements in the first quarter of 2019. The increase in our effective tax rate was primarily due to the impacts of tax settlements.

Operating revenues decreased in the first quarter of 2020, driven by declines in our Entertainment Group and Business Wireline business units, partially offset by increases in our Mobility business unit. The decrease reflects the continued shift away from linear video and legacy services and lower wireless equipment sales attributable to store closures. Largely offsetting these declines were higher wireless service revenues from growth in our prepaid subscriber base and growth in our postpaid phone subscribers and average revenue per subscriber (ARPU).

Service revenue increased in the first quarter of 2020 largely due to higher average revenue per subscriber (ARPU) and growth in Cricket subscribers.

ARPU

ARPU increased in the first quarter primarily due to a continued shift by subscribers to our unlimited plans.

Churn

The effective management of subscriber churn is critical to our ability to maximize revenue growth and to maintain and improve margins. Postpaid churn and postpaid phone-only churn were lower in the first quarter due to pricing changes, competitive offers and industry-wide store closures from COVID-19.

Equipment revenue decreased in the first quarter of 2020 driven by lower postpaid smartphone sales reflecting store closures from COVID-19.

Operations and support expenses decreased in the first quarter of 2020 primarily due to lower cost of equipment sales from lower volumes and advertising expense and continued improvements in cost efficiencies, partially offset by higher bad debt expense.

Depreciation expense increased in the first quarter of 2020 primarily due to ongoing capital spending for network upgrades and expansion partially offset by fully depreciated assets.

Operating income increased in the first quarter of 2020. Our Mobility operating income margin in the first quarter increased from 30.6% in 2019 to 33.3% in 2020. Our Mobility EBITDA margin in the first quarter increased from 42.2% in 2019 to

45.0% in 2020. EBITDA is defined as operating contribution excluding equity in net income (loss) of affiliates and depreciation and amortization.

Subscriber Relationships

As the wireless industry has matured, we believe future wireless growth will depend on our ability to offer innovative services, plans and devices that take advantage of our premier 5G wireless network, and to provide these services in bundled product offerings. Subscribers that purchase two or more services from us have significantly lower churn than subscribers that purchase only one service. To support higher mobile data usage, our priority is to best utilize a wireless network that has sufficient spectrum and capacity to support these innovations on as broad a geographic basis as possible.

To attract and retain subscribers in a mature and highly competitive market, we have launched a wide variety of plans, including our FirstNet and prepaid products, and arrangements that bundle our video services. Virtually all of our postpaid smartphone subscribers are on plans that provide for service on multiple devices at reduced rates, and such subscribers tend to have higher retention and lower churn rates. We offer unlimited data plans and such subscribers also tend to have higher retention and lower churn rates. Our offerings are intended to encourage existing subscribers to upgrade their current services and/or add devices, attract subscribers from other providers and/or minimize subscriber churn.

Connected Devices

Connected devices include data-centric devices such as wholesale automobile systems, monitoring devices, fleet management and session-based tablets. The number of connected device subscriber relationships increased during the first quarter of 2020, driven by the addition of approximately 2.5 million wholesale connected cars through agreements with various carmakers and strong growth in other Internet of Things (IoT) connections. We believe that these connected car agreements give us the opportunity to create future retail relationships with the car owners.

Video entertainment revenues are comprised of subscription and advertising revenues. Revenues decreased in the first quarter of 2020, largely driven by a decline in premium TV subscribers, as we continue to focus on high-value customers, partially offset by subscription-based advertising growth. Consistent with the rest of the industry, our customers continue to shift from a premium linear service to our more economically priced OTT video services, which has pressured our video revenues.

High-speed internet revenues increased in the first quarter of 2020, reflecting higher ARPU resulting from pricing actions and an increase in high-speed fiber connections. Our bundling strategy is helping to lower churn with subscribers who bundle broadband with another AT&T service.

Legacy voice and data service revenues decreased in the first quarter of 2020, reflecting the continued migration of customers to our more advanced IP-based offerings or to competitors.

Operations and support expenses decreased in the first quarter of 2020, primarily due to lower content costs from fewer subscribers and ongoing cost initiatives, partially offset by higher amortization of fulfillment cost deferrals and higher annual content rate increases.

Strategic and managed services revenues increased in the first quarter of 2020. Our strategic services are made up of (1) data services, including our VPN, dedicated internet ethernet and broadband, (2) voice service, including VoIP and cloud-based voice solutions, (3) security and cloud solutions, and (4) managed, professional and outsourcing services. Revenue increases were primarily attributable to growth in our dedicated internet, business internet and security services.

Legacy voice and data service revenues decreased in the first quarter of 2020, primarily due to lower demand as customers continue to shift to our more advanced IP-based offerings and mobile services or our competitors.

Other service and equipment revenues increased in the first quarter of 2020, driven by revenues from customer premises equipment. Revenues from the licensing of intellectual property assets vary from period-to-period and can impact revenue trends. Other service revenues include project-based revenue, which is nonrecurring in nature, as well as revenues from customer premises equipment.

Operations and support expenses decreased in the first quarter of 2020, primarily due to our continued efforts to drive efficiencies in our network operations through automation and reductions in customer support expenses through digitization.

Depreciation expense increased in the first quarter, primarily due to increases in capital spending for network upgrades and expansion.

Operating income decreased in the first quarter of 2020. Our Business Wireline operating income margin in the first quarter decreased from 18.9% in 2019 to 17.1% in 2020. Our Business Wireline EBITDA margin in the first quarter decreased from 37.8% in 2019 to 37.6% in 2020.

Operating revenues decreased in the first quarter of 2020, primarily due to lower theatrical product driven by unfavorable comparisons to the prior comparable period, which included, in 2019, carryover revenues from the theatrical release of Aquaman in addition to a more favorable mix of home entertainment releases. Partially offsetting the theatrical declines were higher television product revenues, driven by licensing, partly offset by lower initial telecast revenues driven by television production delays.

Cost of revenues decreased in the first quarter of 2020, primarily due to lower marketing of theatrical product, partially offset by incremental costs incurred due to the production hiatus.

Selling, general and administrative increased in the first quarter of 2020, primarily due to higher bad debt expense and other charges.

OTHER BUSINESS MATTERS

Spectrum Auction We were the winning bidder of high-frequency 37/39 GHz licenses in FCC Auction 103 covering an average of 786 MHz nationwide for approximately $2,400. Prior to the auction, we exchanged the 39 GHz licenses previously acquired through FiberTower Corporation for vouchers to be applied against the winning bids. These vouchers yielded a value of $1,200 which was applied toward our $2,400 gross bids. We made our final payment of approximately $950 for the Auction 103 payment in April 2020. We expect the FCC will grant the licenses in mid-2020.

Labor Contracts As of March 31, 2020, we employed approximately 244,000 persons. Approximately 40% of our employees are represented by the Communications Workers of America (CWA), the International Brotherhood of Electrical Workers (IBEW) or other unions. After expiration of the collective bargaining agreements, work stoppages or labor disruptions may occur in the absence of new contracts or other agreements being reached.

A contract covering approximately 7,000 Mobility employees expired in February 2020. In March 2020, a new 4-year contract was ratified by employees and will expire in February 2024.

A contract covering approximately 13,000 wireline employees in our West region expired in April 2020. In March 2020, a tentative agreement was reached on a new 4-year contract. The tentative agreement is subject to ratification by employees.

COMPETITIVE AND REGULATORY ENVIRONMENT

Overview AT&T subsidiaries operating within the United States are subject to federal and state regulatory authorities. AT&T subsidiaries operating outside the United States are subject to the jurisdiction of national and supranational regulatory authorities in the markets where service is provided.

In the Telecommunications Act of 1996 (Telecom Act), Congress established a national policy framework intended to bring the benefits of competition and investment in advanced telecommunications facilities and services to all Americans by opening all telecommunications markets to competition and reducing or eliminating regulatory burdens that harm consumer welfare. Nonetheless, over the ensuing two decades, the FCC and some state regulatory commissions have maintained or expanded certain regulatory requirements that were imposed decades ago on our traditional wireline subsidiaries when they operated as legal monopolies. More recently, the FCC has pursued a more deregulatory agenda, eliminating a variety of antiquated and unnecessary regulations and streamlining its processes in a number of areas. In addition, we are pursuing, at both the state and federal levels, additional legislative and regulatory measures to reduce regulatory burdens that are no longer appropriate in a competitive telecommunications market and that inhibit our ability to compete more effectively and offer services wanted and needed by our customers, including initiatives to transition services from traditional networks to all IP-based networks. At the same time, we also seek to ensure that legacy regulations are not further extended to broadband or wireless services, which are subject to vigorous competition.

Communications Segment

Internet The FCC currently classifies fixed and mobile consumer broadband services as information services, subject to light-touch regulation. Although the D.C. Circuit upheld the FCC’s current classification, challenges to that decision remain pending.

A number of states have adopted legislation or issued executive orders that would reimpose net neutrality rules repealed by the FCC, and in some cases, established additional requirements. Suits have been filed concerning laws in certain states, but have been stayed pursuant to agreements by those states not to enforce their laws pending final resolution of all appeals of the FCC order restoring broadband’s status as an information service. We will continue to support congressional action to codify a set of standard consumer rules for the internet.

In October 2016, the FCC adopted new rules governing the use of customer information by providers of broadband internet access service. Those rules were more restrictive in certain respects than those governing other participants in the internet economy, including so-called “edge” providers such as Google and Facebook. In April 2017, the president signed a resolution passed by Congress repealing the new rules under the Congressional Review Act.

Privacy-related legislation has been considered or adopted in a number of states. Legislative and regulatory action could result in increased costs of compliance, claims against broadband internet access service providers and others, and increased uncertainty in the value and availability of data. Effective as of January 1, 2020, a California state law gives consumers the right to know what personal information is being collected about them, and whether and to whom it is sold or disclosed, and to access and request deletion of this information. Subject to certain exceptions, it also gives California consumers the right to opt out of the sale of personal information.

Wireless The industry-wide deployment of 5G technology, which is needed to satisfy extensive demand for video and internet access, will involve significant deployment of “small cell” equipment and therefore increase the need for local permitting processes that allow for the placement of small cell equipment on reasonable timelines and terms. Federal regulations also can delay and impede the deployment of infrastructure used to provide telecommunications and broadband services, including small cell equipment. In March, August and September 2018, the FCC adopted orders to streamline federal and local wireless infrastructure review processes in order to facilitate deployment of next-generation wireless facilities. Specifically, the FCC’s March 2018 Order streamlined historical, tribal, and environmental review requirements for wireless infrastructure, including by excluding most small cell facilities from such review. The Order was appealed and in August 2019, the D.C. Circuit Court of Appeals vacated the FCC’s finding that most small cell facilities are excluded from review, but otherwise upheld the FCC’s Order. The FCC’s August and September 2018 Orders simplified the regulations for attaching telecommunications equipment to utility poles and clarified when local government right-of-way access and use

restrictions can be preempted because they unlawfully prohibit the provision of telecommunications services. Those orders were appealed to the 9th Circuit Court of Appeals, where they remain pending. In addition to the FCC’s actions, to date, 28 states and Puerto Rico have adopted legislation to facilitate small cell deployment.

In December 2018, we introduced the nation’s first commercial mobile 5G service. We now expect nationwide 5G coverage this summer; we anticipate the introduction of 5G handsets and devices will contribute to a renewed interest in equipment upgrades.

LIQUIDITY AND CAPITAL RESOURCES

The Company's liquidity and capital resources were not materially impacted by COVID-19 and related economic conditions during the first quarter of 2020 despite lower business collections late in the quarter as customers extended their payment cycles, presumably in response to the economic challenges of the pandemic. We will continue to monitor impacts on the COVID-19 pandemic on our liquidity and capital resources. For further discussion regarding the potential future impacts of COVID-19 and related economic conditions on the Company's liquidity and capital resources, see "Part II-Item 1A-Risk Factors."

We had $9,955 in “Cash and cash equivalents” available at March 31, 2020. “Cash and cash equivalents” included cash of $3,287 and money market funds and other cash equivalents of $6,668. Approximately $2,485 of our “Cash and cash equivalents” were held by our foreign entities in accounts predominantly outside of the U.S. and may be subject to restrictions on repatriation.

“Cash and cash equivalents” decreased $2,175 since December 31, 2019. In the first three months of 2020, cash inflows were primarily provided by the cash receipts from operations, including cash from our sale and transfer of our receivables to third parties, issuance of long-term debt, issuance of commercial paper and issuances of cumulative preferred stock. These inflows were offset by cash used to meet the needs of the business, including, but not limited to, payment of operating expenses, debt repayments, funding capital expenditures and vendor financing payments, collateral posted to banks and other participants in derivative arrangements, share repurchase, and dividends to stockholders.

Cash Provided by or Used in Operating Activities

During the first three months of 2020, cash provided by operating activities was $8,866, compared to $11,052 for the first three months of 2019. Lower operating cash flows in 2020 were primarily driven by WarnerMedia profits, including increased HBO Max investments and higher production spend; lower incremental receivable securitization; and working capital pressures, specifically lower business collections late in the quarter.

We actively manage the timing of our supplier payments for non-capital items to optimize the use of our cash. Among other things, we seek to have payments made on 90-day or greater terms, while providing the suppliers with access to bank facilities that permit earlier payments at their cost. In addition, for payments to a key supplier, we have arrangements that allow us to extend payment terms up to 90 days at an additional cost to us (referred to as supplier financing). The net impact of supplier financing on cash from operating activities was to decrease working capital $1,075 and $904 for the three months ended March 31, 2020 and 2019, respectively. All supplier financing payments are due within one year.

Cash Used in or Provided by Investing Activities

For the first three months of 2020, cash used in investing activities totaled $5,022, and consisted primarily of $4,966 (including interest during construction) for capital expenditures ($216 lower than the prior-year comparable period), and $99 of wireless spectrum deposits. Subsequent to the first quarter of 2020, in April we made our final payment of approximately $950 for wireless spectrum licenses won in Auction 103, and on May 4, we acquired our remaining interest HBO Latin America Group (HBO LAG) for $230.

For capital improvements, we have negotiated favorable vendor payment terms of 120 days or more (referred to as vendor financing) with some of our vendors, which are excluded from capital expenditures and reported as financing activities. For the first three months of 2020, vendor financing payments were $791, compared to $819 for the first three months of 2019.

Capital expenditures in the first three months of 2020 were $4,966, and when including $791 cash paid for vendor financing, capital investment was $5,757 ($244 lower than the prior-year comparable period).

The vast majority of our capital expenditures are spent on our networks, including product development and related support systems. During the first three month of 2020, we placed $449 of equipment in service under vendor financing arrangements (compared to $733 in the prior-year comparable period) and $338 of assets related to the FirstNet build (compared to $304 in the prior-year comparable period).

The amount of capital expenditures is influenced by demand for services and products, capacity needs and network enhancements.

Cash Provided by or Used in Financing Activities

For the first three months of 2020, cash used in financing activities totaled $6,099 and was comprised of debt issuances and repayments, issuances of preferred stock, share repurchase, payments of dividends and required collateral deposits.

During the first three months of 2020, debt issuances included proceeds of $3,132 in net short-term borrowings and $4,357 of net proceeds from long-term debt, which consisted primarily of the following issuances:

February issuance of $2,995 of 4.000% global notes due 2049.

March draw of $750 on a private financing agreement.

March borrowings of $665 from loan programs with export agencies of foreign governments to support network equipment purchases in those countries.

During the first three months of 2020, repayment of long-term debt totaled $4,422. Repayments primarily consisted of the following:

$800 of AT&T floating-rate notes redeemed at maturity.

$2,619 of 4.600% AT&T global notes with original maturities in 2045.

$750 of borrowings under a private financing agreement.

Our weighted average interest rate of our entire long-term debt portfolio, including the impact of derivatives, was approximately 4.3% as of March 31, 2020 and 4.4% as of December 31, 2019. We had $159,386 of total notes and debentures outstanding at March 31, 2020, which included Euro, British pound sterling, Canadian dollar, Swiss franc, Australian dollar, Brazilian real and Mexican peso denominated debt that totaled approximately $40,712.

At March 31, 2020, we had $17,067 of debt maturing within one year, including $3,144 of commercial paper borrowings and $13,923 of long-term debt issuances. Debt maturing within one year includes the following notes that may be put back to us by the holders:

$1,000 of annual put reset securities issued by BellSouth that may be put back to us each April until maturity in 2021. These securities were redeemed on April 27, 2020.

An accreting zero-coupon note that may be redeemed each May until maturity in 2022. If the remainder of the zero-coupon note (issued for principal of $500 in 2007 and partially exchanged in the 2017 debt exchange offers) is held to maturity, the redemption amount will be $592.

For the first three months of 2020, we paid $791 of cash under our vendor financing program, compared to $819 in the first three months of 2019. Total vendor financing payables included in our March 31, 2020 consolidated balance sheet were approximately $1,361, with $997 due within one year (in “Accounts payable and accrued liabilities”) and the remainder predominantly due within two to three years (in “Other noncurrent liabilities”).

Financing activities in the first three months of 2020 also included $3,869 for the February issuance of Series B and Series C preferred stock. (See Note 10)

During the first three months of 2020, we repurchased approximately 142 million shares of common stock and completed the share repurchase authorization approved by the Board of Directors in 2013. At March 31, 2020, we had approximately 178 million shares remaining from share repurchase authorizations approved by the Board of Directors in 2014. On March 19,

2020, we announced the cancellation of an accelerated share repurchase agreement that was planned for the second quarter and all other repurchases to maintain flexibility and focus on continued investment in serving our customers, taking care of our employees and enhancing our network, including 5G.

We paid dividends on common and preferred shares of $3,737 during the first three months of 2020, compared with $3,714 for the first three months of 2019. Dividends were higher in 2020, primarily due to dividend payments to preferred stockholders and the increase in our quarterly dividend on common stock approved by our Board of Directors in December 2019, partially offset by fewer shares outstanding. Dividends on common stock declared by our Board of Directors totaled $0.52 per share in the first three months of 2020 and $0.51 per share for the first three months of 2019. Our dividend policy considers the expectations and requirements of stockholders, capital funding requirements of AT&T and long-term growth opportunities. It is our intent to provide the financial flexibility to allow our Board of Directors to consider dividend growth and to recommend an increase in dividends to be paid in future periods. All dividends remain subject to declaration by our Board of Directors.

Credit Facilities

The following summary of our various credit and loan agreements does not purport to be complete and is qualified in its entirety by reference to each agreement filed as exhibits to our Annual Report on Form 10-K.

We use credit facilities as a tool in managing our liquidity status. In December 2018, we amended our five-year revolving credit agreement (the “Amended and Restated Credit Agreement”) and concurrently entered into a new five-year agreement (the “Five Year Credit Agreement”) such that we now have two $7,500 revolving credit agreements totaling $15,000. The Amended and Restated Credit Agreement terminates on December 11, 2021 and the Five Year Credit Agreement terminates on December 11, 2023. No amounts were outstanding under either agreement as of March 31, 2020.

In September 2019, we entered into and drew on a $1,300 term loan credit agreement containing (i) a 1.25 year $400 facility due in 2020 (BAML Tranche A Facility), (ii) a 2.25 year $400 facility due in 2021 (BAML Tranche B Facility), and (iii) a 3.25 year $500 facility due in 2022 (BAML Tranche C Facility), with Bank of America, N.A., as agent. No repayment had been made under these facilities as of March 31, 2020.

On April 6, 2020, we entered into and drew on a $5,500 Term Loan Credit Agreement (Term Loan), with 11 commercial banks and Bank of America, N.A., as lead agent. The Term Loan is not subject to amortization and the entire principal amount of the Term Loan will be due and payable on December 31, 2020.

We also utilize other external financing sources, which include various credit arrangements supported by government agencies to support network equipment purchases, as well as a commercial paper program.

Each of our credit and loan agreements contains covenants that are customary for an issuer with an investment grade senior debt credit rating as well as a net debt-to-EBITDA financial ratio covenant requiring AT&T to maintain, as of the last day of each fiscal quarter, a ratio of not more than 3.5-to-1. As of March 31, 2020, we were in compliance with the covenants for our credit facilities.

Collateral Arrangements

During 2019 and 2020, we amended collateral arrangements with certain counterparties to require cash collateral posting by AT&T only when derivative market values exceed certain thresholds. Under these arrangements, counterparties are still required to post collateral. During the first three months of 2020, we deposited approximately $2,650 of cash collateral, on a net basis as we exceeded the market value thresholds with some of the counterparties. Cash postings under these arrangements vary with changes in credit ratings and netting agreements. (See Note 7)

Other

Our total capital consists of debt (long-term debt and debt maturing within one year) and stockholders’ equity. Our capital structure does not include debt issued by our equity method investments. At March 31, 2020, our debt ratio was 45.7%, compared to 47.4% at March 31, 2019 and 44.7% at December 31, 2019. Our net debt ratio was 42.9% at March 31, 2020,

compared to 45.6% at March 31, 2019 and 41.4% at December 31, 2019. The debt ratio is affected by the same factors that affect total capital, and reflects our recent debt issuances, repayments and debt acquired in business combinations.

During the first three months of 2020, we received $118 from the disposition of assets, and when combined with working capital monetization initiatives, which include the sale of receivables, total cash received from monetization efforts, net of spectrum acquisitions, was approximately $1,000. We plan to continue to explore similar opportunities throughout 2020.

Dollars in millions except per share amounts

At March 31, 2020, we had interest rate swaps with a notional value of $853 and a fair value of $14.

We have fixed-to-fixed and floating-to-fixed cross-currency swaps on foreign currency-denominated debt instruments with a U.S. dollar notional value of $42,325 to hedge our exposure to changes in foreign currency exchange rates. These derivatives have been designated at inception and qualify as cash flow hedges with a net fair value of $(8,283) at March 31, 2020. We have rate locks with a notional value of $3,500 and a fair value of $(720) at March 31, 2020.

We have foreign exchange contracts with a U.S. dollar notional value of $106 to provide currency at a fixed rate to hedge a portion of the exchange risk involved in foreign currency-denominated transactions. These foreign exchange contracts include fair value hedges, cash flow hedges and economic (nonqualifying) hedges with a total net fair value of $66 at March 31, 2020.

We have designated €1,364 million aggregate principal amount of debt as a hedge of the variability of certain Euro-denominated net investments of our subsidiaries. The gain or loss on the debt that is designated as, and is effective as, an economic hedge of the net investment in a foreign operation is recorded as a currency translation adjustment within accumulated other comprehensive income, net on the consolidated balance sheet.

Item 4. Controls and Procedures

The registrant maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed by the registrant is recorded, processed, summarized, accumulated and communicated to its management, including its principal executive and principal financial officers, to allow timely decisions regarding required disclosure, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. The chief executive officer and chief financial officer have performed an evaluation of the effectiveness of the design and operation of the registrant’s disclosure controls and procedures as of March 31, 2020. Based on that evaluation, the chief executive officer and chief financial officer concluded that the registrant’s disclosure controls and procedures were effective as of March 31, 2020.

There have not been any changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

CAUTIONARY LANGUAGE CONCERNING FORWARD-LOOKING STATEMENTS

Information set forth in this report contains forward-looking statements that are subject to risks and uncertainties, and actual results could differ materially. Many of these factors are discussed in more detail in the “Risk Factors” section. We claim the protection of the safe harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995.

The following factors could cause our future results to differ materially from those expressed in the forward-looking statements:

The severity, magnitude and duration of the COVID-19 pandemic and containment, mitigation and other measures taken in response, including the potential impacts of these matters on our business and operations.

Our inability to predict the extent to which the COVID-19 pandemic and related impacts will continue to impact our business operations, financial performance and results of operations.

Adverse economic, political and/or capital access changes in the markets served by us or in countries in which we have significant investments and/or operations, including the impact on customer demand and our ability and our suppliers’ ability to access financial markets at favorable rates and terms.

Increases in our benefit plans’ costs, including increases due to adverse changes in the United States and foreign securities markets, resulting in worse-than-assumed investment returns and discount rates; adverse changes in mortality assumptions; adverse medical cost trends; and unfavorable or delayed implementation or repeal of healthcare legislation, regulations or related court decisions.

The final outcome of FCC and other federal, state or foreign government agency proceedings (including judicial review, if any, of such proceedings) and legislative efforts involving issues that are important to our business, including, without limitation, pending Notices of Apparent Liability; the transition from legacy technologies to IP-based infrastructure, including the withdrawal of legacy TDM-based services; universal service; broadband deployment; wireless equipment siting regulations and, in particular, siting for 5G service; E911 services; competition policy; privacy; net neutrality; multichannel video programming distributor services and equipment; content licensing and copyright protection; availability of new spectrum on fair and balanced terms; and wireless and satellite license awards and renewals.

Enactment of additional state, local, federal and/or foreign regulatory and tax laws and regulations, or changes to existing standards and actions by tax agencies and judicial authorities including the resolution of disputes with any taxing jurisdictions, pertaining to our subsidiaries and foreign investments, including laws and regulations that reduce our incentive to invest in our networks, resulting in lower revenue growth and/or higher operating costs.

Potential changes to the electromagnetic spectrum currently used for broadcast television and satellite distribution being considered by the FCC could negatively impact WarnerMedia’s ability to deliver linear network feeds of its domestic cable networks to its affiliates, and in some cases, WarnerMedia’s ability to produce high-value news and entertainment programming on location.

U.S. and foreign laws and regulations regarding intellectual property rights protection and privacy, personal data protection and user consent are complex and rapidly evolving and could result in adverse impacts to our business plans, increased costs, or claims against us that may harm our reputation.

The ability of our competitors to offer product/service offerings at lower prices due to lower cost structures and regulatory and legislative actions adverse to us, including non-regulation of comparable alternative technologies and/or government-owned or subsidized networks.

The continued development and delivery of attractive and profitable wireless, video and broadband offerings and devices, and, in particular, the success of our new HBO Max platform; the extent to which regulatory and build-out requirements apply to our offerings; our ability to match speeds offered by our competitors and the availability, cost and/or reliability of the various technologies and/or content required to provide such offerings.

Our ability to generate advertising revenue from attractive video content, especially from WarnerMedia, in the face of unpredictable and rapidly evolving public viewing habits and legal restrictions on the use of personal data.

The availability and cost and our ability to adequately fund additional wireless spectrum and network upgrades; and regulations and conditions relating to spectrum use, licensing, obtaining additional spectrum, technical standards and deployment and usage, including network management rules.

Our ability to manage growth in wireless data services, including network quality and acquisition of adequate spectrum at reasonable costs and terms.

The outcome of pending, threatened or potential litigation (which includes arbitrations), including, without limitation, patent and product safety claims by or against third parties.

CAUTIONARY LANGUAGE CONCERNING FORWARD-LOOKING STATEMENTS

The impact from major equipment or software failures on our networks, including satellites operated by DIRECTV; the effect of security breaches related to the network or customer information; our inability to obtain handsets, equipment/software or have handsets, equipment/software serviced in a timely and cost-effective manner from suppliers; and in the case of satellites launched, timely provisioning of services from vendors; or severe weather conditions including flooding and hurricanes, natural disasters including earthquakes and forest fires, pandemics, energy shortages, wars or terrorist attacks.

The issuance by the Financial Accounting Standards Board or other accounting oversight bodies of new accounting standards or changes to existing standards.

Our ability to successfully integrate our WarnerMedia operations, including the ability to manage various businesses in widely dispersed business locations and with decentralized management.

Changes in our corporate strategies, such as changing network-related requirements or acquisitions and dispositions, which may require significant amounts of cash or stock, to respond to competition and regulatory, legislative and technological developments.

The uncertainty surrounding further congressional action to address spending reductions, which may result in a significant decrease in government spending and reluctance of businesses and consumers to spend in general.

Readers are cautioned that other factors discussed in this report, although not enumerated here, also could materially affect our future earnings.

Item 1A. Risk Factors

We discuss in our Annual Report on Form 10-K various risks that may materially affect our business. We use this section to update this discussion to reflect material developments since our Form 10-K was filed.

We depend on various suppliers to provide equipment to operate our business and satisfy customer demand and interruption or delay in supply can adversely impact our operating results.

We depend on suppliers to provide us, directly or through other suppliers, with items such as network equipment, customer premises equipment, video equipment and wireless-related equipment such as mobile hotspots, handsets, wirelessly enabled computers, wireless data cards and other connected devices for our customers. These suppliers could fail to provide equipment on a timely basis, or fail to meet our performance expectations, for a number of reasons, including, difficulties in obtaining export licenses for certain technology, inability to secure component parts, general business disruption, natural disasters, safety issues, economic and political instability and public health emergencies such as the COVID-19 pandemic. The COVID-19 pandemic has caused, and may continue to cause, delays in the development, manufacturing (including the sourcing of key components) and shipment of products. In certain limited circumstances, suppliers have been unable to supply products in a timely fashion. In such limited circumstances, we have been unable to provide products and services precisely as and when requested by our customers. It is possible that, in some circumstances, we could be forced to switch to a different key supplier. Because of the cost and time lag that can be associated with transitioning from one supplier to another, our business could be substantially disrupted if we were required to, or chose to, replace the products of one or more key suppliers with products from another source, especially if the replacement became necessary on short notice. Any such disruption could increase our costs, decrease our operating efficiencies and have a negative effect on our operating results.

Our business is subject to risks arising from the recent outbreak of the COVID-19 virus.

The COVID-19 pandemic and resulting mitigation measures have caused, and may continue to cause, a negative effect on our operating results. To date, mitigation measures have caused sports leagues to suspend operations as well as the cancellation of many sporting events, including the NCAA tournament, which has adversely affected our advertising revenues, may result in contract disputes concerning carriage rights and will also cause us to incur expenses relating to these sporting events notwithstanding their cancellation. The closure, or the avoidance, of theaters, and the interruptions in movie production and other programming caused by COVID-19, are expected to impact the timing of revenues and may cause a loss of revenue to our Warner Media business over the long term. If the mitigating measures or the associated effects are prolonged, we expect business customers in industries most significantly impacted will reduce or terminate services, having a negative effect on the performance of our Business Wireline business unit. Further, concerns over the COVID-19 pandemic could result in the prolonged closure of many of our retail stores and deter customers from accessing our stores even as the mitigation measures subside. These pandemic concerns may also result in continued impact to our customers’ ability to pay for our products and services. We may also continue to see significant impact on roaming revenues due to a downturn in international travel. The COVID-19 pandemic has reduced staffing levels at our call centers and field operations resulting in delays in service. Further reductions in staffing levels could further limit our ability to provide services, adversely impacting our competitive position. We may also incur significantly higher expenses attributable to infrastructure investments required to meet higher network utilization from more customers consuming bandwidth from changes in work from home trends; extended cancellation periods; and increased labor costs if the COVID-19 pandemic continues for an extended period.

The COVID-19 pandemic and mitigation measures have caused, and may continue to cause, adverse impacts on global economic conditions and consumer confidence and spending, which affect demand for our products and services. The extent to which the COVID-19 pandemic impacts our business results of operations, cash flows and financial condition will depend on future developments that are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and the actions to contain its impact. Due to the speed with which the situation is developing, we are not able at this time to estimate the impact of COVID-19 on our financial or operational results, but the impact could be material.

Segment Information

Segment Information [Text Block]

NOTE 4. SEGMENT INFORMATION

Our segments are strategic business units that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We analyze our segments based on segment operating contribution, which consists of operating income, excluding acquisition-related costs and other significant items (as discussed below), and equity in net income (loss) of affiliates for investments managed within each segment. We have four reportable segments: (1) Communications, (2) WarnerMedia, (3) Latin America, and (4) Xandr.

We also evaluate segment and business unit performance based on EBITDA and/or EBITDA margin, which is defined as operating contribution excluding equity in net income (loss) of affiliates and depreciation and amortization. We believe EBITDA to be a relevant and useful measurement to our investors as it is part of our internal management reporting and planning processes and it is an important metric that management uses to evaluate operating performance. EBITDA does not

give effect to cash used for debt service requirements and thus does not reflect available funds for distributions, reinvestment or other discretionary uses. EBITDA margin is EBITDA divided by total revenues.

The Communications segment provides wireless and wireline telecom, video and broadband services to consumers located in the U.S. and businesses globally. This segment contains the following business units:

Mobility provides nationwide wireless service and equipment.

Entertainment Group provides video, including over-the-top (OTT) services, broadband and voice communications services primarily to residential customers. This segment also sells advertising on distribution platforms.

Business Wireline provides advanced IP-based services, as well as traditional voice and data services to business customers.

The WarnerMedia segment develops, produces and distributes feature films, television, gaming and other content in various physical and digital formats globally. This segment contains the following business units:

Turner primarily operates multichannel basic television networks and digital properties. Turner also sells advertising on its networks and digital properties.

Home Box Office consists of premium pay television and OTT and streaming services domestically and premium pay, basic tier television and OTT services internationally, as well as content licensing and home entertainment.

Warner Bros. primarily consists of the production, distribution and licensing of television programming and feature films, the distribution of home entertainment products and the production and distribution of games.

The Latin America segment provides entertainment and wireless services outside of the U.S. This segment contains the following business units:

Vrio provides video services primarily to residential customers using satellite technology in Latin America and the Caribbean.

Mexico provides wireless service and equipment to customers in Mexico.

The Xandr segment provides advertising services. These services utilize data insights to develop and deliver targeted advertising across video and digital platforms. Certain revenues in this segment are also reported by the Communications segment and are eliminated upon consolidation.

Corporate and Other reconciles our segment results to consolidated operating income and income before income taxes, and includes:

Corporate, which consists of: (1) businesses no longer integral to our operations or which we no longer actively market, (2) corporate support functions, (3) impacts of corporate-wide decisions for which the individual operating segments are not being evaluated and (4) the reclassification of the amortization of prior service credits, which we continue to report with segment operating expenses, to consolidated “Other income (expense) – net.”

Acquisition-related items which consists of items associated with the merger and integration of acquired businesses, including amortization of intangible assets.

Certain significant items includes (1) employee separation charges associated with voluntary and/or strategic offers, (2) losses resulting from abandonment or impairment of assets and (3) other items for which the segments are not being evaluated.

Eliminations and consolidations, which (1) removes transactions involving dealings between our segments, including content licensing between WarnerMedia and Communications, and (2) includes adjustments for our reporting of the advertising business.

“Interest expense” and “Other income (expense) – net,” are managed only on a total company basis and are, accordingly, reflected only in consolidated results.

Finance Receivables Disclosure[Text Block]

NOTE 8. SALES OF RECEIVABLES

We have agreements with various third-party financial institutions pertaining to the sales of certain types of our accounts receivable. The most significant of these programs are discussed in detail below and generally consist of (1) receivables arising from equipment installment plans, which are sold for cash and a deferred purchase price, and (2) revolving service and trade receivables. Under these programs, we transfer receivables to purchasers in exchange for cash and additional consideration upon settlement of the receivables, where applicable. Under the terms of our agreements for these programs, we continue to bill and collect the payments from our customers on behalf of the financial institutions.

The sales of receivables did not have a material impact on our consolidated statements of income or to “Total Assets” reported on our consolidated balance sheets. We reflect cash receipts on sold receivables as cash flows from operations in our

consolidated statements of cash flows. Cash receipts on the deferred purchase price are classified as cash flows from investing activities.

Our equipment installment and revolving receivable programs are discussed in detail below. The following table sets forth a summary of the receivables and accounts being serviced:

			March 31, 2020				December 31, 2019

Equipment Installment Receivables Program

We offer our customers the option to purchase certain wireless devices in installments over a specified period of time and, in many cases, once certain conditions are met, they may be eligible to trade in the original equipment for a new device and have the remaining unpaid balance paid or settled.

We maintain a program under which we transfer a portion of these receivables through our bankruptcy-remote subsidiary in exchange for cash and additional consideration upon settlement of the receivables, referred to as the deferred purchase price. In the event a customer trades in a device prior to the end of the installment contract period, we agree to make a payment to the financial institutions equal to any outstanding remaining installment receivable balance. Accordingly, we record a guarantee obligation for this estimated amount at the time the receivables are transferred.

The following table sets forth a summary of equipment installment receivables sold under this program during the three months ended March 31, 2020 and 2019:

		Three months ended March 31,
			2020		2019
Gross receivables sold		$	2,367	$	2,701
Net receivables sold1			2,273		2,546
Cash proceeds received			1,950		2,275
Deferred purchase price recorded			353		309
Guarantee obligation recorded			44		101
1	Receivables net of allowance, imputed interest and equipment trade-in right guarantees.

The deferred purchase price and guarantee obligation are initially recorded at estimated fair value and subsequently adjusted for changes in present value of expected cash flows. The estimation of their fair values is based on remaining installment payments expected to be collected and the expected timing and value of device trade-ins. The estimated value of the device trade-ins considers prices offered to us by independent third parties that contemplate changes in value after the launch of a

device model. The fair value measurements used for the deferred purchase price and the guarantee obligation are considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7).

The following table presents the previously transferred equipment installment receivables, which we repurchased in exchange for the associated deferred purchase price during the three months ended March 31, 2020 and 2019:

		Three months ended March 31,
			2020		2019
Fair value of repurchased receivables		$	288	$	423
Carrying value of deferred purchase price			277		407
Gain on repurchases1		$	11	$	16
1	These gains are included in “Selling, general and administrative” in the consolidated statements of income.

At March 31, 2020 and December 31, 2019, our deferred purchase price receivable was $2,378 and $2,336, respectively, of which $1,583 and $1,569 are included in “Other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at March 31, 2020 and December 31, 2019 was $351 and $384, respectively, of which $189 and $148 are included in “Accounts payable and accrued liabilities” on our consolidated balance sheets, with the remainder in “Other noncurrent liabilities.” Our maximum exposure to loss as a result of selling these equipment installment receivables is limited to the total amount of our deferred purchase price and guarantee obligation.

Revolving Receivables Program

In 2019, we entered into a revolving agreement to transfer up to $4,300 of certain receivables through our bankruptcy-remote subsidiaries to various financial institutions on a recurring basis in exchange for cash equal to the gross receivables transferred. In the first quarter of 2020, we expanded the program limit to $5,300. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts (e.g., collect and reinvest). The transferred receivables are fully guaranteed by our bankruptcy-remote subsidiaries, which hold additional receivables in the amount of $4,057 that are pledged as collateral under this agreement. The transfers are recorded at fair value of the proceeds received and obligations assumed less derecognized receivables. The obligation is subsequently adjusted for changes in estimated expected credit losses. Our maximum exposure to loss related to these receivables transferred is limited to the amount outstanding.

The fair value measurement used for the obligation is considered Level 3 under the Fair Value Measurement and Disclosure framework (see Note 7).

The following table sets forth a summary of receivables sold:

			Three months ended March 31,
			2020		2019
Gross receivables sold/cash proceeds received1		$	4,222	$	1,400

Preparation Of Interim Financial Statements (Policy)

3 Months Ended

Mar. 31, 2020

Accounting Policies [Abstract]

Principles of Consolidation [Policy Text Block]

All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included for periods ended within up to one quarter of our period end. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items.

Basis of Accounting [Policy Text Block]

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including potential impacts arising from the COVID-19 pandemic, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation.

Credit Loss, Financial Instrument [Policy Text Block]

Credit Losses As of January 1, 2020, we adopted, through modified retrospective application, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13, as amended), which replaces the incurred loss impairment methodology under prior GAAP with an expected credit loss model. ASU 2016-13 affects trade receivables, loans, contract assets, certain beneficial interests, off-balance-sheet credit exposures not accounted for as insurance and other financial assets that are not subject to fair value through net income, as defined by the standard. Under the expected credit loss model, we are required to consider future economic trends to estimate expected credit losses over the lifetime of the asset. Upon adoption, we recorded a $293 reduction to “Retained earnings,” $395 increase to “allowances for doubtful accounts” applicable to our trade and loan receivables, $10 reduction of contract assets, $105 reduction of net deferred income tax liability and $7 reduction of “Noncontrolling interest” as an opening adjustment. Our adoption of ASU 2016-13 did not have a material impact on our financial statements.

Reference Rate Reform [Policy Text Block]

Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), which provides optional expedients, and allows for certain exceptions to existing GAAP, for contract modifications triggered by the expected market transition of certain benchmark interest rates to alternative reference rates. ASU 2020-04 applies to contracts, hedging relationships and other arrangements that reference the London Interbank Offering Rate (LIBOR) or any other rates ending after December 31, 2022. We are evaluating the impact of our adoption of ASU 2020-04, including optional expedients, for impact to our financial statements.

Spectrum Licenses [Policy Text Block]

Intangible Assets During the first quarter of 2020, in conjunction with the nationwide launch of AT&T TV and our customers’ continued shift from linear to streaming video services, we reassessed the estimated economic lives and renewal assumptions for our orbital slot licenses. As a result, we have changed the estimated lives of these licenses from indefinite to finite-lived, effective January 1, 2020, and began amortizing our orbital slot licenses using the sum-of-months-digits method over their average remaining economic life of 15 years. This change in accounting increased amortization expense $386, or $0.04 per diluted share available to common stock during the first quarter of 2020.

We also reassessed and changed the estimated economic lives of certain trade names in our Latin America business from indefinite to finite-lived and began amortizing them using the straight-line method over their average remaining economic life of 15 years. This change had an insignificant impact on our financial statements.

Fair Value Measurements And Disclosure

Fair Value Disclosures

Fair Value Measurements And Disclosure [Text Block]

NOTE 7. FAIR VALUE MEASUREMENTS AND DISCLOSURE

The Fair Value Measurement and Disclosure framework in ASC 820, “Fair Value Measurement,” provides a three-tiered fair value hierarchy based on the reliability of the inputs used to determine fair value. Level 1 refers to fair values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant other observable inputs and Level 3 includes fair values estimated using significant unobservable inputs.

The level of an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs.

The valuation methodologies described above may produce a fair value calculation that may not be indicative of future net realizable value or reflective of future fair values. We believe our valuation methods are appropriate and consistent with other market participants. The use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. There have been no changes in the methodologies used since December 31, 2019.

Long-Term Debt and Other Financial Instruments

The carrying amounts and estimated fair values of our long-term debt, including current maturities, and other financial instruments, are summarized as follows:

		March 31, 2020				December 31, 2019
		Carrying		Fair		Carrying		Fair
		Amount		Value		Amount		Value
Notes and debentures1		$	159,386	$	175,902	$	161,109	$	182,124
Commercial paper			3,144		3,144		-		-
Bank borrowings			-		-		4		4
Investment securities2			3,591		3,591		3,723		3,723
1	Includes credit agreement borrowings.
2	Excludes investments accounted for under the equity method.

The carrying amount of debt with an original maturity of less than one year approximates fair value. The fair value measurements used for notes and debentures are considered Level 2 and are determined using various methods, including quoted prices for identical or similar securities in both active and inactive markets.

Following is the fair value leveling for investment securities that are measured at fair value and derivatives as of March 31, 2020 and December 31, 2019. Derivatives designated as hedging instruments are reflected as “Other assets,” “Other noncurrent liabilities” and, for a portion of interest rate swaps, “Other current assets” on our consolidated balance sheets.

Investment Securities

Our investment securities include both equity and debt securities that are measured at fair value, as well as equity securities without readily determinable fair values. A substantial portion of the fair values of our investment securities is estimated based on quoted market prices. Investments in equity securities not traded on a national securities exchange are valued at cost, less any impairment, and adjusted for changes resulting from observable, orderly transactions for identical or similar securities. Investments in debt securities not traded on a national securities exchange are valued using pricing models, quoted prices of securities with similar characteristics or discounted cash flows.

The components comprising total gains and losses in the period on equity securities are as follows:

	Three months ended
	March 31,
	2020		2019
Total gains (losses) recognized on equity securities	$	(203)	$	160
Gains (losses) recognized on equity securities sold		(33)		18
Unrealized gains (losses) recognized on equity securities held at end of period		(170)		142

At March 31, 2020, available-for-sale debt securities totaling $1,514 have maturities as follows - less than one year: $78; one to three years: $149; three to five years: $160; for five or more years: $1,127.

Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and nonrefundable customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments and nonrefundable customer deposits are recorded in “Other current assets” and our investment securities are recorded in “Other Assets” on the consolidated balance sheets.

Derivative Financial Instruments

We enter into derivative transactions to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged.

Fair Value Hedging We designate our fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount.

We also designate some of our foreign exchange contracts as fair value hedges. The purpose of these contracts is to hedge currency risk associated with foreign-currency-denominated operating assets and liabilities.

Accrued and realized gains or losses from fair value hedges impact the same category on the consolidated statements of income as the item being hedged. Unrealized gains on fair value hedges are recorded at fair market value as assets, and unrealized losses are recorded at fair market value as liabilities. Changes in the fair value of derivative instruments designated as fair value hedges are offset against the change in fair value of the hedged assets or liabilities through earnings. In the three months ended March 31, 2020 and 2019, no ineffectiveness was measured on fair value hedges.

Cash Flow Hedging We designate our cross-currency swaps as cash flow hedges. We have entered into multiple cross-currency swaps to hedge our exposure to variability in expected future cash flows that are attributable to foreign currency risk generated from the issuance of our foreign-denominated debt. These agreements include initial and final exchanges of principal from fixed foreign currency denominated amounts to fixed U.S. dollar denominated amounts, to be exchanged at a specified rate that is usually determined by the market spot rate upon issuance. They also include an interest rate swap of a fixed or floating foreign currency-denominated interest rate to a fixed U.S. dollar denominated interest rate.

We also designate some of our foreign exchange contracts as cash flow hedges. The purpose of these contracts is to hedge certain film production costs denominated in foreign currencies.

Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, changes in fair value are reported as a component of accumulated OCI and are reclassified into the consolidated statements of income in the same period the hedged transaction affects earnings.

Periodically, we enter into and designate interest rate locks to partially hedge the risk of changes in interest payments attributable to increases in the benchmark interest rate during the period leading up to the probable issuance of fixed-rate debt. We designate our interest rate locks as cash flow hedges. Gains and losses when we settle our interest rate locks are amortized into income over the life of the related debt. Over the next 12 months, we expect to reclassify $60 from accumulated OCI to “Interest expense” due to the amortization of net losses on historical interest rate locks.

Net Investment Hedging We have designated €1,364 million aggregate principal amount of debt as a hedge of the variability of some of the Euro-denominated net investments of our subsidiaries. The gain or loss on the debt that is designated as, and is effective as, an economic hedge of the net investment in a foreign operation is recorded as a currency translation adjustment within accumulated OCI, net on the consolidated balance sheet. Net gains on net investment hedges recognized in accumulated OCI for 2020 were $25.

Collateral and Credit-Risk Contingency We have entered into agreements with our derivative counterparties establishing collateral thresholds based on respective credit ratings and netting agreements. At March 31, 2020, we had posted collateral of $2,809 (a deposit asset) and held no collateral. Under the agreements, if AT&T’s credit rating had been downgraded one rating level by Fitch Ratings before the end of March, we would not have been required to post any additional collateral. If AT&T’s credit rating had been downgraded four rating levels by Fitch Ratings, two levels by S&P, and two levels by Moody’s, we would have been required to post additional collateral of $6,149. If DIRECTV Holdings LLC’s credit rating had been downgraded below BBB- (S&P), we would have been required to post additional collateral of $200. At December 31, 2019, we had posted collateral of $204 (a deposit asset) and held collateral of $44 (a receipt liability). We do not offset the fair value of collateral, whether the right to reclaim cash collateral (a receivable) or the obligation to return cash collateral (a payable) exists, against the fair value of the derivative instruments.

Following are the notional amounts of our outstanding derivative positions:

	March 31,		December 31,
	2020		2019

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

NOTE 9. LEASES

We have operating and finance leases for certain facilities and equipment used in operations. Our leases generally have remaining lease terms of up to 15 years. Some of our real estate operating leases contain renewal options that may be exercised, and some of our leases include options to terminate the leases within one year.

We have recognized a right-of-use asset for both operating and finance leases, and an operating lease liability that represents the present value of our obligation to make payments over the lease term. The present value of the lease payments is calculated using the incremental borrowing rate for operating and finance leases, which was determined using a portfolio approach based on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. We use the unsecured borrowing rate and risk-adjust that rate to approximate a collateralized rate in the currency of the lease, which will be updated on a quarterly basis for measurement of new lease liabilities.

The components of lease expense were as follows:

	Three months ended March 31,
	2020		2019
Operating lease cost	$	1,377	$	1,242
Finance lease cost:

Preparation Of Interim Financial Statements

3 Months Ended

Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS

Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications, media and technology industries. You should read this document in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2019. The results for the interim periods are not necessarily indicative of those for the full year. These consolidated financial statements include all adjustments that are necessary to present fairly the results for the presented interim periods, consisting of normal recurring accruals and other items.

All significant intercompany transactions are eliminated in the consolidation process. Investments in subsidiaries and partnerships which we do not control but have significant influence are accounted for under the equity method. Earnings from certain investments accounted for using the equity method are included for periods ended within up to one quarter of our period end. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including potential impacts arising from the COVID-19 pandemic, that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation.

Credit Losses As of January 1, 2020, we adopted, through modified retrospective application, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (ASU 2016-13, as amended), which replaces the incurred loss impairment methodology under prior GAAP with an expected credit loss model. ASU 2016-13 affects trade receivables, loans, contract assets, certain beneficial interests, off-balance-sheet credit exposures not accounted for as insurance and other financial assets that are not subject to fair value through net income, as defined by the standard. Under the expected credit loss model, we are required to consider future economic trends to estimate expected credit losses over the lifetime of the asset. Upon adoption, we recorded a $293 reduction to “Retained earnings,” $395 increase to “allowances for doubtful accounts” applicable to our trade and loan receivables, $10 reduction of contract assets, $105 reduction of net deferred income tax liability and $7 reduction of “Noncontrolling interest” as an opening adjustment. Our adoption of ASU 2016-13 did not have a material impact on our financial statements.

Reference Rate Reform In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (ASU 2020-04), which provides optional expedients, and allows for certain exceptions to existing GAAP, for contract modifications triggered by the expected market transition of certain benchmark interest rates to alternative reference rates. ASU 2020-04 applies to contracts, hedging relationships and other arrangements that reference the London Interbank Offering Rate (LIBOR) or any other rates ending after December 31, 2022. We are evaluating the impact of our adoption of ASU 2020-04, including optional expedients, for impact to our financial statements.

Intangible Assets During the first quarter of 2020, in conjunction with the nationwide launch of AT&T TV and our customers’ continued shift from linear to streaming video services, we reassessed the estimated economic lives and renewal assumptions for our orbital slot licenses. As a result, we have changed the estimated lives of these licenses from indefinite to finite-lived, effective January 1, 2020, and began amortizing our orbital slot licenses using the sum-of-months-digits method over their average remaining economic life of 15 years. This change in accounting increased amortization expense $386, or $0.04 per diluted share available to common stock during the first quarter of 2020.

We also reassessed and changed the estimated economic lives of certain trade names in our Latin America business from indefinite to finite-lived and began amortizing them using the straight-line method over their average remaining economic life of 15 years. This change had an insignificant impact on our financial statements.

Deferred Customer Contract Acquisition and Fulfillment Costs

Costs to acquire and fulfill customer contracts, including commissions on service activations, for our wireless, business wireline and video entertainment services, are deferred and amortized over the contract period or expected customer relationship life, which typically ranges from three years to five years. For contracts with an estimated amortization period of less than one year, we expense incremental costs immediately.

The following table presents the deferred customer contract acquisition costs and deferred customer contract fulfillment costs included on our consolidated balance sheets:

		March 31,		December 31,
Consolidated Balance Sheets		2020		2019
Deferred Acquisition Costs
Other current assets	$	2,592	$	2,462

Other current assets		4,438		4,519
Other Assets		6,279		6,439
Total deferred customer contract fulfillment costs	$	10,717	$	10,958

The following table presents deferred customer contract acquisition cost and deferred customer contract fulfillment cost amortization included in “Other cost of revenue” for the three months ended:

		March 31,		March 31,
Consolidated Statements of Income		2020		2019
Deferred acquisition cost amortization	$	636	$	547
Deferred fulfillment cost amortization		1,305		1,098

Contract Assets and Liabilities

A contract asset is recorded when revenue is recognized in advance of our right to bill and receive consideration. The contract asset will decrease as services are provided and billed. For example, when installment sales include promotional discounts (e.g., “buy one get one free”) the difference between revenue recognized and consideration received is recorded as a contract asset to be amortized over the contract term.

When consideration is received in advance of the delivery of goods or services, a contract liability is recorded for deferred revenue. Reductions in the contract liability will be recorded as we satisfy the performance obligations.

The following table presents contract assets and liabilities on our consolidated balance sheets:

		March 31,		December 31,
		2020		2019
Contract asset	$	2,598	$	2,472
Contract liability		6,757		6,999

Our beginning of period contract liability recorded as customer contract revenue during 2020 was $4,519.

Our consolidated balance sheets at March 31, 2020 and December 31, 2019 included approximately $1,700 and $1,611, respectively, for the current portion of our contract asset in “Other current assets” and $5,769 and $5,939, respectively, for the current portion of our contract liability in “Advanced billings and customer deposits.”

Remaining Performance Obligations

Remaining performance obligations represent services we are required to provide to customers under bundled or discounted arrangements, which are satisfied as services are provided over the contract term. In determining the transaction price allocated, we do not include non-recurring charges and estimates for usage, nor do we consider arrangements with an original expected duration of less than one year, which are primarily prepaid wireless, video and residential internet agreements.

Remaining performance obligations associated with business contracts reflect recurring charges billed, adjusted to reflect estimates for sales incentives and revenue adjustments. Performance obligations associated with wireless contracts are estimated using a portfolio approach in which we review all relevant promotional activities, calculating the remaining performance obligation using the average service component for the portfolio and the average device price. As of March 31, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $36,486, of which we expect to recognize approximately 86% by the end of 2021, with the balance recognized thereafter.

NOTE 6. PENSION AND POSTRETIREMENT BENEFITS

Many of our employees are covered by one of our noncontributory pension plans. We also provide certain medical, dental, life insurance and death benefits to certain retired employees under various plans and accrue actuarially determined postretirement benefit costs. Our objective in funding these plans, in combination with the standards of the Employee Retirement Income Security Act of 1974, as amended (ERISA), is to accumulate assets sufficient to provide benefits described in the plans to employees upon their retirement. We do not have significant funding requirements in 2020.

We recognize actuarial gains and losses on pension and postretirement plan assets in our consolidated results as a component of “Other income (expense) – net” at our annual measurement date of December 31, unless earlier remeasurements are required.

The following table details pension and postretirement benefit costs included in the accompanying consolidated statements of income. The service cost component of net periodic pension cost (benefit) is recorded in operating expenses in the consolidated statements of income while the remaining components are recorded in “Other income (expense) – net.”
