Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting PoliciesNOTE 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 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. Intangible Assets Driven by significant and adverse economic and political environments in Latin America, including the impact of the COVID-19 pandemic, we have 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, 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. 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. 379, or $ 0.04 per diluted share available to common stock during the second quarter and $ 765, or $ 0.08, per diluted share available to common stock for the first six months of 2020.

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 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 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. 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 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. 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 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 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.

The following table presents the deferred customer contract acquisition and fulfillment costs included on our consolidated balance sheets: June 30, December 31, Consolidated Balance Sheets 2020 2019 Deferred Acquisition Costs Other current assets $ 2,630 $ 2,462 Other Assets 3,117 2,991 Total deferred customer contract acquisition costs $ 5,747 $ 5,453 Deferred Fulfillment Costs Other current assets $ 4,362 $ 4,519 Other Assets 5,980 6,439 Total deferred customer contract fulfillment costs $ 10,342 $ 10,958 The following table presents deferred customer contract acquisition and fulfillment cost amortization included in “Other cost of revenue” for the six months ended: June 30, June 30, Consolidated Statements of Income 2020 2019 Deferred acquisition cost amortization $ 1,278 $ 1,026 Deferred fulfillment cost amortization 2,636 2,381 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: June 30, December 31, Consolidated Balance Sheets 2020 2019 Contract asset $ 2,546 $ 2,472 Contract liability 6,533 6,999 Our beginning of period contract liability recorded as customer contract revenue during 2020 was $ 5,004. Our consolidated balance sheets at June 30, 2020 and December 31, 2019 included approximately $ 1,638 and $ 1,611, respectively, for the current portion of our contract asset in “Other current assets” and $ 5,616 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 June 30, 2020, the aggregate amount of the transaction price allocated to remaining performance obligations was $ 36,362, of which we expect to recognize approximately 82% by the end of 2021, with the balance recognized thereafter.

Pension And Postretirement Benefits
Pension and Other Postretirement Benefits Disclosure [Text Block]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.” Three months ended Six months ended June 30, June 30, 2020 2019 2020 2019 Pension cost: Service cost – benefits earned during the period $ 258 $ 243 $ 515 $ 483 Interest cost on projected benefit obligation 422 508 844 1,057 Expected return on assets ( 890) ( 880) ( 1,779) ( 1,731) Amortization of prior service credit ( 29) ( 24) ( 57) ( 57) Actuarial (gain) loss - 1,699 - 2,131 Net pension (credit) cost $ ( 239) $ 1,546 $ ( 477) $ 1,883 Postretirement cost: Service cost – benefits earned during the period $ 13 $ 18 $ 26 $ 36 Interest cost on accumulated postretirement benefit obligation 104 186 208 372 Expected return on assets ( 45) ( 56) ( 89) ( 112) Amortization of prior service credit ( 582) ( 426) ( 1,164) ( 852) Net postretirement (credit) cost $ ( 510) $ ( 278) $ ( 1,019) $ ( 556) Combined net pension and postretirement (credit) cost $ ( 749) $ 1,268 $ ( 1,496) $ 1,327 We also provide senior- and middle-management employees with nonqualified, unfunded supplemental retirement and savings plans. Net supplemental pension benefits costs not included in the table above were $ 19 and $ 25 in the second quarter and $ 38 and $ 50 for the first six months of 2020 and 2019, respectively.

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: June 30, 2020 December 31, 2019 Carrying Fair Carrying Fair Amount Value Amount Value Notes and debentures 1 $ 164,099 $ 190,284 $ 161,109 $ 182,124 Commercial paper 3,001 3,001 - - Bank borrowings - - 4 4 Investment securities 2 3,632 3,632 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 June 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 Six months ended June 30, June 30, 2020 2019 2020 2019 Total gains (losses) recognized on equity securities $ 161 $ 50 $ ( 42) $ 210 Gains (Losses) recognized on equity securities sold 9 9 ( 24) 27 Unrealized gains (losses) recognized on equity securities held at end of period 152 41 ( 18) 183 At June 30, 2020, available-for-sale debt securities totaling $ 1,522 have maturities as follows - less than one year: $ 64; one to three years: $ 175; three to five years: $ 156; 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 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. 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 six months ended June 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 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 $ 98 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 issuance of fixed rate debt obligations that the interest rate locks were hedging. We 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 second quarter were $ 30 and for the first six months of 2020 were $ 5. 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 June 30, 2020, we had posted collateral of $ 694 (a deposit asset) and held collateral of $ 16 (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 June, we would have been required to post additional collateral of $ 76. 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 $ 5,487. 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 $ 321. 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 Adjustments [Text Block]NOTE 8. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS Acquisitions HBO Latin America Group (HBO LAG) In May 2020 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 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.

Finance Receivables Disclosure[Text Block]NOTE 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: June 30, 2020 December 31, 2019 Equipment Equipment Installment Revolving Installment Revolving Gross receivables: $ 3,931 $ 3,745 $ 4,576 $ 3,324 Balance sheet classification Accounts receivable Notes receivable 2,056 - 2,467 - Trade receivables 496 3,547 477 2,809 Other Assets Noncurrent notes and trade receivables 1,379 198 1,632 515 Outstanding portfolio of receivables derecognized from our consolidated balance sheets 8,917 5,300 9,713 4,300 Cash proceeds received, net of remittances 1 6,429 5,300 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 six months ended June 30, 2020 and 2019: Three months ended Six months ended June 30, June 30, 2020 2019 2020 2019 Gross receivables sold $ 1,506 $ 2,244 $ 3,873 $ 4,945 Net receivables sold 1 1,449 2,133 3,722 4,679 Cash proceeds received 1,225 1,920 3,175 4,195 Deferred purchase price recorded 232 261 585 570 Guarantee obligation recorded 27 93 71 194 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 six months ended June 30, 2020 and 2019: Three months ended Six months ended June 30, June 30, 2020 2019 2020 2019 Fair value of repurchased receivables $ 285 $ 235 $ 573 $ 658 Carrying value of deferred purchase price 281 225 558 632 Gain on repurchases 1 $ 4 $ 10 $ 15 $ 26 1 These gains are included in “Selling, general and administrative” in the consolidated statements of income. At June 30, 2020 and December 31, 2019, our deferred purchase price receivable was $ 2,319 and $ 2,336, respectively, of which $ 1,591 and $ 1,569 are included in “Other current assets” on our consolidated balance sheets, with the remainder in “Other Assets.” The guarantee obligation at June 30, 2020 and December 31, 2019 was $ 315 and $ 384, respectively, of which $ 213 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 $ 3,745 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 Six months ended June 30, June 30, 2020 2019 2020 2019 Gross receivables sold/cash proceeds received 1 $ 3,805 $ 4,452 $ 8,027 $ 5,852 Collections reinvested under revolving agreement 3,805 2,127 7,027 2,127 Net cash proceeds received (remitted) $ - $ 2,325 $ 1,000 $ 3,725 Net receivables sold 2 $ 3,819 $ 4,134 $ 7,957 $ 5,497 Obligations recorded (reversed) ( 12) 384 114 436 1 Includes initial sale of receivables of $ 0 and $ 2,325 for the three months and $ 1,000 and $ 3,725 for the six months ended June 30, 2020 and 2019, respectively. 2 Receivables net of allowance, return and incentive reserves and imputed interest

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]NOTE 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 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 Six months ended June 30, June 30, 2020 2019 2020 2019 Operating lease cost $ 1,449 $ 1,610 $ 2,826 $ 2,852 Finance lease cost: Amortization of right-of-use assets $ 73 $ 70 $ 140 $ 136 Interest on lease obligation 36 42 77 84 Total finance lease cost $ 109 $ 112 $ 217 $ 220 Supplemental balance sheet information related to leases is as follows: June 30, December 31, 2020 2019 Operating Leases Operating lease right-of-use assets $ 24,692 $ 24,039 Accounts payable and accrued liabilities $ 3,474 $ 3,451 Operating lease obligation 22,230 21,804 Total operating lease obligation $ 25,704 $ 25,255 Finance Leases Property, plant and equipment, at cost $ 3,468 $ 3,534 Accumulated depreciation and amortization ( 1,347) ( 1,296) Property, plant and equipment, net $ 2,121 $ 2,238 Current portion of long-term debt $ 180 $ 162 Long-term debt 1,683 1,872 Total finance lease obligation $ 1,863 $ 2,034 Weighted-Average Remaining Lease Term (years) Operating leases 8.5 8.4 Finance leases 10.2 10.7 Weighted-Average Discount Rate Operating leases 4.2 % 4.7 % Finance leases 8.2 % 8.5 % Future minimum maturities of lease obligations are as follows: At June 30, 2020 Operating Finance Leases Leases Remainder of 2020 $ 2,447 $ 190 2021 4,582 309 2022 4,277 291 2023 3,889 262 2024 3,357 242 Thereafter 13,031 1,632 Total lease payments 31,583 2,926 Less imputed interest ( 5,879) ( 1,063) Total $ 25,704 $ 1,863

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, including the combination of our prior Xandr segment with the WarnerMedia segment.
Credit Loss, Financial Instrument [Policy Text Block]Credit Losses As of January 1, 2020 , we adopted, through modified retrospective 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, to our financial statements.
Spectrum Licenses [Policy Text Block]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. 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. 379, or $ 0.04 per diluted share available to common stock during the second quarter and $ 765, or $ 0.08, per diluted share available to common stock for the first six months of 2020.
