Accounting Policies [Abstract]
Preparation Of Interim Financial StatementsNOTE 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, including the combination of our prior Xandr segment with the WarnerMedia segment. 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, to our financial statements. Convertible Instruments In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity” (ASU 2020-06), which eliminated certain separation models regarding cash conversion and beneficial conversion features to simplify reporting for convertible instruments as a single liability or equity, with no separate accounting for embedded conversion features. ASU 2020-06 will be effective for fiscal years beginning after December 31, 2021, under modified retrospective or full retrospective application, subject to early adoption in 2021. We are evaluating the impact of our adoption of ASU 2020-06 on our financial statements. Intangible Assets In the second quarter, driven by significant and adverse economic and political environments in Latin America, including the impact of the COVID-19 pandemic, we experienced accelerated subscriber losses and revenue decline in the region, as well as closure of our operations in Venezuela. When combining these business trends and higher weighted-average cost of capital resulting from the increase in country-risk premiums in the region, we concluded that it is more likely than not that the fair value of the Vrio reporting unit, estimated using discounted cash flow and market multiple approaches, is less than its carrying amount. We recorded a $2,212 goodwill impairment in the reporting unit in the second quarter, with $105 attributable to noncontrolling interest. The impairment is not deductible for tax purposes and resulted in an increase in our effective tax rate. During the first quarter of 2020, we 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. Also 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 $373, or $0.04 per diluted share available to common stock during the third quarter and $1,138, or $0.12, per diluted share available to common stock for the first nine months of 2020.

Segment Reporting [Abstract]
Segment InformationNOTE 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 three reportable segments: (1) Communications, (2) WarnerMedia and (3) Latin America. We have recast our segment results for all prior periods to include our prior Xandr segment within our WarnerMedia segment. 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 records advertising revenue. • 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. Historical financial results from Xandr, previously a separate reportable segment, have been combined with the WarnerMedia segment within Eliminations and other. This segment contains the following: • 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. • Eliminations & Other includes the Xandr advertising business and Otter Media Holdings operations, and also removes transactions between the Turner, Home Box Office and Warner Bros. business units, including internal sales of content to the HBO Max platform that began in the fourth quarter of 2019 (see Note 5). 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. 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 , which includes (1) employee separation charges associated with voluntary and/or strategic offers, (2) losses resulting from abandonment of network assets and impairments, 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 channel distribution 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 and fulfillment costs included on our consolidated balance sheets: September 30, December 31, Consolidated Balance Sheets 2020 2019 Deferred Acquisition Costs Other current assets $ 2,831 $ 2,462 Other Assets 3,114 2,991 Total deferred customer contract acquisition costs $ 5,945 $ 5,453 Deferred Fulfillment Costs Other current assets $ 4,234 $ 4,519 Other Assets 5,781 6,439 Total deferred customer contract fulfillment costs $ 10,015 $ 10,958 The following table presents deferred customer contract acquisition and fulfillment cost amortization included in “Other cost of revenue” for the nine months ended: September 30, September 30, Consolidated Statements of Income 2020 2019 Deferred acquisition cost amortization $ 1,969 $ 1,565 Deferred fulfillment cost amortization 3,888 3,656 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: September 30, December 31, Consolidated Balance Sheets 2020 2019 Contract asset $ 2,817 $ 2,472 Contract liability 6,617 6,999 Our beginning of period contract liability recorded as customer contract revenue during 2020 was $5,340. Our consolidated balance sheets at September 30, 2020 and December 31, 2019 included $1,729 and $1,611, respectively, for the current portion of our contract asset in “Other current assets” and $5,762 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.

Pension And Postretirement BenefitsNOTE 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.” Three months ended Nine months ended September 30, September 30, 2020 2019 2020 2019 Pension cost: Service cost - benefits earned during the period $ 257 $ 260 $ 772 $ 743 Interest cost on projected benefit obligation 421 463 1,265 1,520 Expected return on assets (888) (905) (2,667) (2,636) Amortization of prior service credit (28) (28) (85) (85) Actuarial (gain) loss — 1,888 — 4,019 Net pension (credit) cost $ (238) $ 1,678 $ (715) $ 3,561 Postretirement cost: Service cost – benefits earned during the period $ 14 $ 19 $ 40 $ 55 Interest cost on accumulated postretirement benefit obligation 104 185 312 557 Expected return on assets (44) (57) (133) (169) Amortization of prior service credit (583) (425) (1,747) (1,277) Net postretirement (credit) cost $ (509) $ (278) $ (1,528) $ (834) Combined net pension and postretirement (credit) cost $ (747) $ 1,400 $ (2,243) $ 2,727

Fair Value Disclosures [Abstract]
Fair Value Measurements And DisclosureNOTE 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: September 30, 2020 December 31, 2019 Carrying Fair Carrying Fair Amount Value Amount Value Notes and debentures 1 $ 155,218 $ 181,872 $ 161,109 $ 182,124 Commercial paper 1,754 1,754 — — Bank borrowings — — 4 4 Investment securities 2 3,669 3,669 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 September 30, 2020 and December 31, 2019. Derivatives designated as hedging instruments are reflected as “Other assets,” “Other noncurrent liabilities,” “Other current assets” and “Accounts payable and accrued liabilities” on our consolidated balance sheets.

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 Nine months ended September 30, September 30, 2020 2019 2020 2019 Total gains (losses) recognized on equity securities $ 64 $ 21 $ 22 $ 231 Gains (Losses) recognized on equity securities sold — 74 (24) 101 Unrealized gains (losses) recognized on equity securities held at end of period $ 64 $ (53) $ 46 $ 130 At September 30, 2020, available-for-sale debt securities totaling $1,524 have maturities as follows - less than one year: $62; one to three years: $155; three to five years: $163; five or more years: $1,144. 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 Periodically, we enter into and designate 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. Unrealized 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 derivatives designated as 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 nine months ended September 30, 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 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 forecasted film production costs and film tax incentives 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 $95 from accumulated OCI to “Interest expense” due to the amortization of net losses on historical interest rate locks. We settled all interest rate locks in May 2020 in conjunction with the issuance of fixed rate debt obligations that the interest rate locks were hedging and paid $731 that was largely offset by the return of collateral at the time of settlement. Cash flows from the interest rate lock settlements and return of collateral were reported as Financing Activities in our Statement of Cash Flows, consistent with our accounting policy for these instruments. Net Investment Hedging We have designated €1,450 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 losses on net investment hedges recognized in accumulated OCI in the third quarter were $70 and for the first nine months of 2020 were $75. 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 September 30, 2020, we had posted collateral of $485 (a deposit asset) and held collateral of $4 (a receipt liability). Under the agreements, if AT&T’s credit rating had been downgraded one rating level by Fitch Ratings, before the final collateral exchange in September, we would have been required to post additional collateral of $25. If AT&T’s credit rating had been downgraded four ratings 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 $3,237. If DIRECTV Holdings LLC’s credit rating had been downgraded below BBB- by S&P, we would have been required to post additional collateral of $241. 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.

Acquisitions, Dispositions And Other AdjustmentsNOTE 8. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS Acquisitions HBO Latin America Group (HBO LAG) In May 2020, we acquired the remaining interest in HBO LAG for $141, net of cash acquired. At acquisition, we remeasured the fair value of the total business, which exceeded the carrying amount of our equity method investment and resulted in a pre-tax gain of $68. We consolidated that business upon close and recorded those assets at fair value, including $640 of trade names, $271 of distribution networks and $343 of goodwill that is reported in the WarnerMedia segment. These estimates are preliminary in nature and subject to adjustments, which will be finalized within one year from the date of acquisition. Spectrum Auctions In June 2020, we completed the acquisition of $2,379 of 37/39 GHz spectrum in a Federal Communications Commission (FCC) auction. Prior to the auction, we exchanged the 39 GHz licenses with a book value of approximately $300 that were previously acquired through FiberTower Corporation for vouchers to be applied against the winning bids and recorded a $900 gain in the first quarter of 2020. These vouchers yielded a value of approximately $1,200, which was applied toward our gross bids. In the second quarter of 2020, we made the final cash payment of $949, bringing the total cash payment to $1,186. Dispositions Subsequent to the Third Quarter Central European Media Enterprises Ltd. (CME) On October 13, 2020, we completed the sale of our 65.3% interest in CME, a European broadcasting company, and received $1,100. Upon close, we received relief from a debt guarantee originally covering approximately $1,100 that was reduced to $600 by September 30, 2020. Operations in Puerto Rico On October 31, 2020, we completed the sale of wireless and wireline operations in Puerto Rico and the U.S. Virgin Islands for approximately $1,950. These operations were classified as held-for-sale, and, accordingly, we included the assets in “Other current assets,” and the related liabilities in “Accounts payable and accrued liabilities,” on our consolidated balance sheet at September 30, 2020. The proceeds will be used to redeem $1,950 of cumulative preferred interests in a subsidiary that held notes secured by the proceeds of this sale.

Receivables [Abstract]
Sales Of ReceivablesNOTE 9. 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: September 30, 2020 December 31, 2019 Equipment Equipment Installment Revolving Installment Revolving Gross receivables: $ 4,241 $ 3,516 $ 4,576 $ 3,324 Balance sheet classification Accounts receivable Notes receivable 2,190 — 2,467 — Trade receivables 481 3,329 477 2,809 Other Assets Noncurrent notes and trade receivables 1,570 187 1,632 515 Outstanding portfolio of receivables derecognized from our consolidated balance sheets 8,238 5,100 9,713 4,300 Cash proceeds received, net of remittances 1 5,944 5,100 7,211 4,300 1 Represents amounts to which financial institutions remain entitled, excluding the deferred purchase price. 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 and nine months ended September 30, 2020 and 2019: Three months ended Nine months ended September 30, September 30, 2020 2019 2020 2019 Gross receivables sold $ 1,624 $ 2,098 $ 5,497 $ 7,043 Net receivables sold 1 1,578 2,014 5,300 6,693 Cash proceeds received 1,387 1,700 4,562 5,895 Deferred purchase price recorded 226 352 811 922 Guarantee obligation recorded 55 67 126 261 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 and nine months ended September 30, 2020 and 2019: Three months ended Nine months ended September 30, September 30, 2020 2019 2020 2019 Fair value of repurchased receivables $ 373 $ 268 $ 946 $ 926 Carrying value of deferred purchase price 373 259 931 891 Gain on repurchases 1 $ — $ 9 $ 15 $ 35 1 These gains are included in "Selling, general and administrative" in the consolidated statements of income. At September 30, 2020 and December 31, 2019, our deferred purchase price receivable was $2,163 and $2,336, respectively, of which $1,538 and $1,569 are included in “Other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at September 30, 2020 and December 31, 2019 was $319 and $384, respectively, of which $234 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 one-year 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. In the second quarter of 2020, we extended the agreement by one year. 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 $3,516 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 and interest rates. 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 Nine months ended September 30, September 30, 2020 2019 2020 2019 Gross receivables sold/cash proceeds received 1 $ 3,563 $ 2,873 $ 11,590 $ 8,725 Collections reinvested under revolving agreement 3,563 2,873 10,590 5,000 Collections not reinvested 200 269 200 269 Net cash proceeds received (remitted) $ (200) $ (269) $ 800 $ 3,456 Net receivables sold 2 $ 3,553 $ 2,864 $ 11,510 $ 8,361 Obligations recorded (reversed) 58 39 172 475 1 There were no initial sales of receivables in either of the three-month periods and $1,000 and $3,725 for the nine months ended September 30, 2020 and 2019, respectively. 2 Receivables net of allowance, return and incentive reserves and imputed interest.

Leases [Abstract]
LeasesNOTE 10. 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.

Stockholders' Equity Note [Abstract]
Stockholders' EquityNOTE 11. STOCKHOLDERS' EQUITY We have authorized 10 million preferred shares of AT&T stock, each with a par value of $1.00 per share. Cumulative perpetual preferred shares consist of the following: • Series A: 48 thousand shares outstanding at September 30, 2020 and December 31, 2019, with a $25,000 per share liquidation preference and a dividend rate of 5.00%. • Series B: 20 thousand shares outstanding at September 30, 2020 and zero issued and outstanding at December 31, 2019, with a €100,000 per share liquidation preference, and an initial dividend rate of 2.875%, subject to reset beginning on May 1, 2025. • Series C: 70 thousand shares outstanding at September 30, 2020 and zero issued and outstanding at December 31, 2019, with a $25,000 per share liquidation preference and a dividend rate of 4.75%. So long as the preferred dividends are declared and paid on a timely basis on each series of preferred shares, there are no limitations on our ability to declare a dividend on or repurchase AT&T common shares. The preferred shares are optionally redeemable by AT&T at the liquidation price generally on or after five years from the issuance date, or upon certain other contingent events. Telco LLC In September 2020, we issued $2,000 nonconvertible cumulative preferred interests out of a newly created limited liability company (Telco LLC) that was formed to hold telecommunication-related assets. The preferred interests are entitled to cash distributions, subject to declaration and are included in “Noncontrolling interest” on the consolidated balance sheets. Members’ equity in Telco LLC consist of (1) member’s interests, which are held by a consolidated subsidiary of AT&T, and (2) preferred interests (Telco preferred interests), which pay an initial preferred distribution of 4.25% annually, subject to declaration, and subject to reset every seven years. Failure to pay distributions on the Telco preferred interests would not limit cash movements between affiliates, or our ability to declare a dividend on or repurchase AT&T shares. We can call the Telco preferred interests at the issue price beginning seven years from the issuance date. The Telco preferred interests holders have the option to require redemption upon the occurrence of certain contingent events, such as the failure of Telco LLC to pay the preferred distribution for two or more periods or to meet certain other requirements, including a minimum credit rating. If notice is given, all other holders of equal or more subordinate classes of members equity are entitled to receive the same form of consideration payable to the holders of the preferred interests, resulting in a deemed liquidation for accounting purposes.

For the first nine months, we recorded vendor financing commitments related to capital investments of approximately $3,148 in 2020 and $1,917 in 2019. Total vendor financing payables included in our September 30, 2020 consolidated balance sheet were approximately $3,252, with $1,474 due within one year (in “Accounts payable and accrued liabilities”) and the remainder predominantly due within two Financing Activities Debt Transactions At September 30, 2020, our total long-term debt obligations totaled $158,878. Our debt activity during the nine months ended September 30, 2020 primarily consisted of the following: • Net borrowings of approximately $1,710 of debt under our commercial paper program during the first nine months. • Entry into and draw on a $5,500 Term Loan Credit Agreement, with certain commercial banks and Bank of America, N.A., as lead agent, in April 2020, which was redeemed in May 2020 (originally due on December 31, 2020). • Issuance of $16,545 of AT&T global notes due 2027 to 2060 in the second quarter. • Issuance of €3,000 million global notes ($3,281 at issuance) due 2028 to 2038 in the second quarter. • Issuance of $11,000 of global notes due 2028 to 2061 in the third quarter. • Redemption of $12,689 of AT&T global notes due 2020 to 2047 in the second quarter. • Redemption of $1,800 under term loan credit agreements with certain banks in the second quarter. • Redemption of $1,000 annual put reset securities issued by BellSouth in the second quarter. • Redemption of $4,264 of AT&T, WarnerMedia and DIRECTV notes due 2022 in the third quarter. • Redemption of $1,158 of AT&T and WarnerMedia global notes due 2022 to 2023 in the third quarter. • Redemption of €2,250 of AT&T floating-rate notes due 2020 (approximately $2,637 at maturity) in the third quarter. • Redemption of R$3,381 of Sky Serviços de Banda Larga Ltda. floating-rate private loan due 2021 (approximately $1,000 when issued in April 2018 and $638 at redemption due to strengthening of the U.S. dollar against Brazilian real) in the third quarter. • Repurchases of $11,384 of AT&T global notes and subsidiary notes due 2021 to 2025 tendered for cash in the third quarter. • Exchange of $17,677 of AT&T and subsidiary notes, due 2031 to 2058, for $1,459 of cash and $21,500 of three new series of AT&T global notes due 2053 to 2059 in the third quarter.

Preparation Of Interim Financ_2

Preparation Of Interim Financial Statements (Policies)9 Months Ended
Sep. 30, 2020
Accounting Policies [Abstract]
Principles of ConsolidationAll 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 AccountingThe 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, including the combination of our prior Xandr segment with the WarnerMedia segment.
Credit LossesCredit 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 and Convertible InstrumentsReference 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, to our financial statements. Convertible Instruments In August 2020, the FASB issued ASU No. 2020-06, “Debt—Debt With Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity” (ASU 2020-06), which eliminated certain separation models regarding cash conversion and beneficial conversion features to simplify reporting for convertible instruments as a single liability or equity, with no separate accounting for embedded conversion features. ASU 2020-06 will be effective for fiscal years beginning after December 31, 2021, under modified retrospective or full retrospective application, subject to early adoption in 2021. We are evaluating the impact of our adoption of ASU 2020-06 on our financial statements.
Intangible AssetsIntangible Assets In the second quarter, driven by significant and adverse economic and political environments in Latin America, including the impact of the COVID-19 pandemic, we experienced accelerated subscriber losses and revenue decline in the region, as well as closure of our operations in Venezuela. When combining these business trends and higher weighted-average cost of capital resulting from the increase in country-risk premiums in the region, we concluded that it is more likely than not that the fair value of the Vrio reporting unit, estimated using discounted cash flow and market multiple approaches, is less than its carrying amount. We recorded a $2,212 goodwill impairment in the reporting unit in the second quarter, with $105 attributable to noncontrolling interest. The impairment is not deductible for tax purposes and resulted in an increase in our effective tax rate. During the first quarter of 2020, we 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. Also 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 $373, or $0.04 per diluted share available to common stock during the third quarter and $1,138, or $0.12, per diluted share available to common stock for the first nine months of 2020.
Recognition of Actuarial Gains and LossesWe 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.
Derivatives, Offsetting Fair Value AmountsWe 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.
