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, including the operating results of Warner Media, LLC (referred to as “Time Warner” or “WarnerMedia”), which was acquired on June 14, 2018 (see Note 8). Our operating results for 2018 include the results from Time Warner following the acquisition date. 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, 2018. 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 that affect the amounts reported in the financial statements and accompanying notes, including estimates of probable losses and expenses. Actual results could differ from those estimates. Certain prior period amounts have been conformed to the current period’s presentation. In the tables throughout this document, percentage increases and decreases that are not considered meaningful are denoted with a dash. Adopted Accounting Standards and Other Changes Leases As of January 1, 2019, we adopted, with modified retrospective The key change upon adoption of the standard was balance sheet recognition, given that the recognition of lease expense on our income statement is similar to our historical accounting. Using the modified retrospective transition method of adoption, we did not adjust the balance sheet for comparative periods but recorded a cumulative effect adjustment to retained earnings on January 1, 2019. We elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed us to carry forward our historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements that were not accounted for as leases. We excluded all the leases with original terms of one year or less. Additionally, we elected to not separate lease and non-lease components for certain classes of assets in arrangements where we are the lessee and for certain classes of assets where we are the lessor. Our accounting for finance leases did not change from our prior accounting for capital leases. The adoption of ASC 842 resulted in the recognition of an operating lease liability of $ 22,121 20,960. The cumulative effect of the adoption to retained earnings was an increase of $ 316 reflecting the reclassification of deferred gains related to sale/leaseback transactions. We do not believe the standard will materially impact our future income statements or have a notable impact on our liquidity. The standard will have no impact on our debt-covenant compliance under our current agreements. Deferral of Episodic Television and Film Costs In March 2019, the FASB issued ASU No. 2019-02, “ Entertainment—Films—Other Assets—Film Costs (Subtopic 926-20) and Entertainment—Broadcasters—Intangibles—Goodwill and Other (Subtopic 920-350): Improvements to Accounting for Costs of Films and License Agreements for Program Materials” (ASU 2019-02), which we early adopted as of January 1, 2019 , with prospective 2,274 Spectrum Licenses in Mexico During the first quarter of 2019, in conjunction with the renewal process of certain spectrum licenses in Mexico, we reassessed the estimated economic lives and renewal assumptions for these licenses. As a result, we have changed the life of these licenses from indefinite to finite-lived. On January 1, 2019, we began amortizing our spectrum licenses in Mexico over their average remaining economic life of 25 years. This change in accounting does not materially impact our income statement. Recently Issued Accounting Standards Credit Loss Standard In June 2016, the FASB issued 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 current GAAP. ASU 2016-13 affects trade receivables, loans and other financial assets that are not subject to fair value through net income, as defined by the standard. The amendments under ASU 2016-13 will be effective for years beginning after December 15, 2019, and interim periods within those years. We are currently evaluating ASU 2016-13 but do not anticipate it will have a material impact on our financial statements.

Segment Information
Segment Information [Text Block]NOTE 4. SEGMENT INFORMATION Our segments are strategic business units that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We analyze our segments based on segment operating contribution, which consists of operating income, excluding acquisition-related costs and other significant items (as discussed below), and equity in net income (loss) of affiliates for investments managed within each segment. We have four 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. or in U.S. territories 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 DIRECTV and U-verse 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 AT&T’s Regional Sports Networks (RSNs) and equity investments (predominantly Game Show Network and Otter Media), previously included in Entertainment Group, have been reclassified into the WarnerMedia segment and are combined with the Time Warner operations for the period subsequent to our acquisition on June 14, 2018. This segment contains the following business units:  Turner is comprised of the historic Turner division as well as the financial results of our RSNs. This business unit 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 services domestically and premium pay, basic tier television and OTT services internationally, as well as content licensing and home entertainment.  Warner Bros. 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:  Mexico provides wireless service and equipment to customers in Mexico.  Vrio provides video services primarily to residential customers using satellite technology in Latin America and the Caribbean. The Xandr segment provides advertising services and includes AppNexus, an advertising technology company we acquired in August 2018 . Corporate and Other reconcile our segment results to consolidated operating income and income before income taxes, and include:  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, (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 and (5) the recharacterization of programming intangible asset amortization, for released programming acquired in the Time Warner acquisition, which we continue to report within WarnerMedia segment operating expense, to consolidated amortization expense. The programming and intangible asset amortization reclass was $ 112 in the second quarter and $ 262 for the first six months of 2019.  Acquisition-related items which consists of items associated with the merger and integration of acquired businesses, including amortization of intangible assets.  Certain significant items includes (1) employee separation charges associated with voluntary and/or strategic offers, (2) losses resulting from abandonment or impairment of assets and (3) other items for which the segments are not being evaluated.  Eliminations and consolidations , which (1) removes transactions involving dealings between our segments, including content licensing between WarnerMedia and Communications, and (2) includes adjustments for our reporting of the advertising business. Interest expense and other income (expense) – net, are managed only on a total company basis and are, accordingly, reflected only in consolidated results.

The following table presents the deferred customer contract acquisition costs and deferred customer contract fulfillment costs included on our consolidated balance sheets: June 30, December 31, Consolidated Balance Sheets 2019 2018 Deferred Acquisition Costs Other current assets $ 1,952 $ 1,901 Other Assets 2,760 2,073 Total deferred customer contract acquisition costs 4,712 3,974 Deferred Fulfillment Costs Other current assets 4,620 4,090 Other Assets 6,796 7,450 Total deferred customer contract fulfillment costs $ 11,416 $ 11,540 The following table presents deferred customer contract acquisition cost and deferred customer contract fulfillment cost amortization for the six months ended: June 30, June 30, Consolidated Statements of Income 2019 2018 Deferred acquisition cost amortization $ 1,026 $ 595 Deferred fulfillment cost amortization 2,381 1,889 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 2019 2018 Contract asset $ 2,188 $ 1,896 Contract liability 6,653 6,856 Our January 1, 2019 contract liability recorded as customer contract revenue during 2019 was $ 4,974. Our consolidated balance sheets at June 30, 2019 and December 31, 2018 included approximately $ 1,463 and $ 1,244, respectively, for the current portion of our contract asset in “Other current assets” and $ 5,533 and $ 5,752, 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, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $ 40,646, of which we expect to recognize approximately 80% by the end of 2020, 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. In first quarter of 2019, for certain management participants in our pension plan who terminated employment before April 1, 2019, we offered the option of more favorable 2018 interest rates and mortality basis for determining lump-sum distributions. For the quarter ended March 31, 2019, we recorded special termination benefits of $ 93 associated with this offer in “Other income (expense) – net.” We also committed to a plan to offer certain terminated vested pension plan participants the opportunity to receive their benefit in a lump-sum amount. 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. We anticipate total distributions from the pension plan will exceed the threshold of service and interest costs for 2019, requiring us to follow settlement accounting and remeasure our pension benefit obligation each quarter-end of 2019. These remeasurements resulted in the recognition of actuarial losses of $ 432 and $ 1,699 in the first and second quarters of 2019, respectively. As part of our 2019 remeasurements, we decreased the weighted-average discount rate used to measure our pension benefit obligation from 4.50% at December 31, 2018 to 4.10% at March 31, 2019, and to 3.70% at June 30, 2019. The discount rate in effect for determining pension service and interest costs after remeasurement is 3.90% and 3.25%, respectively. Our remeasurements also reflect actual returns on plan assets of 10.0% (six-month rate). Our expected long-term rate of return on pension plan assets is an annualized 7.00% for the remainder of 2019. 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, 2019 2018 2019 2018 Pension cost: Service cost – benefits earned during the period $ 243 $ 284 $ 483 $ 575 Interest cost on projected benefit obligation 508 504 1,057 991 Expected return on assets ( 880) ( 755) ( 1,731) ( 1,515) Amortization of prior service credit ( 24) ( 29) ( 57) ( 59) Actuarial (gain) loss 1,699 ( 1,796) 2,131 ( 1,796) Net pension (credit) cost $ 1,546 $ ( 1,792) $ 1,883 $ ( 1,804) Postretirement cost: Service cost – benefits earned during the period $ 18 $ 26 $ 36 $ 55 Interest cost on accumulated postretirement benefit obligation 186 195 372 386 Expected return on assets ( 56) ( 75) ( 112) ( 152) Amortization of prior service credit ( 426) ( 413) ( 852) ( 810) Actuarial (gain) loss - - - ( 930) Net postretirement (credit) cost $ ( 278) $ ( 267) $ ( 556) $ ( 1,451) Combined net pension and postretirement (credit) cost $ 1,268 $ ( 2,059) $ 1,327 $ ( 3,255) 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 $ 25 and $ 21 in the second quarter and $ 50 and $ 42 for the first six months of 2019 and 2018, 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 fair value measurements 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, 2018. 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, 2019 December 31, 2018 Carrying Fair Carrying Fair Amount Value Amount Value Notes and debentures 1 $ 165,443 $ 181,230 $ 171,529 $ 172,287 Commercial paper 3,164 3,164 3,048 3,048 Bank borrowings 4 4 4 4 Investment securities 2 3,518 3,518 3,409 3,409 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 market 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 and derivatives that are measured at fair value as of June 30, 2019 and December 31, 2018. Derivatives designated as hedging instruments are reflected as “Other assets,” “Other noncurrent liabilities” and, for a portion of interest rate swaps, “Other current assets” on our consolidated balance sheets.

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 on equity securities are as follows: Three months ended Six months ended June 30, June 30, 2019 2018 2019 2018 Total gains (losses) recognized on equity securities $ 50 $ 21 $ 210 $ 8 Gains (Losses) recognized on equity securities sold 69 ( 3) 155 49 Unrealized gains (losses) recognized on equity securities held at end of period ( 19) 24 55 ( 41) At June 30, 2019, available-for-sale debt securities totaling $ 1,031 have maturities as follows - less than one year: $ 26; one to three years: $ 185; three to five years: $ 151; five or more years: $ 669. Our cash equivalents (money market securities), short-term investments (certificate and time deposits) and nonrefundable customer deposits are recorded at amortized cost, and the respective carrying amounts approximate fair values. Short-term investments and nonrefundable customer deposits are recorded in “Other current assets” and our investment securities are recorded in “Other Assets” on the consolidated balance sheets. Derivative Financial Instruments We enter into derivative transactions to manage certain market risks, primarily interest rate risk and foreign currency exchange risk. This includes the use of interest rate swaps, interest rate locks, foreign exchange forward contracts and combined interest rate foreign exchange contracts (cross-currency swaps). We do not use derivatives for trading or speculative purposes. We record derivatives on our consolidated balance sheets at fair value that is derived from observable market data, including yield curves and foreign exchange rates (all of our derivatives are Level 2). Cash flows associated with derivative instruments are presented in the same category on the consolidated statements of cash flows as the item being hedged. Fair Value Hedging We designate our fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and floating-rate debt. These swaps involve the receipt of fixed-rate amounts for floating interest rate payments over the life of the swaps without exchange of the underlying principal amount. We also designate some of our foreign exchange contracts as fair value hedges. The purpose of these contracts is to hedge currency risk associated with foreign-currency-denominated operating assets and liabilities. Accrued and realized gains or losses from fair value hedges impact the same category on the consolidated statements of income as the item being hedged. Unrealized gains on fair value hedges are recorded at fair market value as assets, and unrealized losses are recorded at fair market value as liabilities. Changes in the fair value of derivative instruments designated as fair value hedges are offset against the change in fair value of the hedged assets or liabilities through earnings. In the six months ended June 30, 2019 and 2018, 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 currency risk associated with variability in anticipated foreign-currency-denominated cash flows, such as unremitted or forecasted royalty and license fees owed to WarnerMedia’s domestic companies for the sale or anticipated sale of U.S. copyrighted products abroad or cash flows for certain film production costs denominated in a foreign currency. 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, the effective portion is reported as a component of accumulated OCI until reclassified into the consolidated statements of income in the same period the hedged transaction affects earnings. The gain or loss on the ineffective portion is recognized as “Other income (expense) – net” in the consolidated statements of income in each period. We evaluate the effectiveness of our cash flow hedges each quarter. In the six months ended June 30, 2019 and 2018, no ineffectiveness was measured on cash flow hedges. 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 from the settlement of our interest rate locks are amortized into income over the life of the related debt, except where a material amount is deemed to be ineffective, which would be immediately reclassified to “Other income (expense) – net” in the consolidated statements of income. Over the next 12 months, we expect to reclassify $ 63 from accumulated OCI to interest expense due to the amortization of net losses on historical interest rate locks. Net Investment Hedging We have designated € 700 million aggregate principal amount of debt as a hedge of the variability of some of the Euro-denominated net investments of WarnerMedia. 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. 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, 2019, we had posted collateral of $ 242 (a deposit asset) and held collateral of $ 86 (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 $ 137. 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 $ 2,668. 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 $ 262. At December 31, 2018, we had posted collateral of $ 1,675 (a deposit asset) and held collateral of $ 103 (a receipt liability).

Acquisitions, Dispositions And Other Adjustments [Text Block]NOTE 8. ACQUISITIONS, DISPOSITIONS AND OTHER ADJUSTMENTS Acquisitions Time Warner On June 14, 2018, we completed our acquisition of Time Warner, a leader in media and entertainment whose major businesses encompass an array of some of the most respected media brands. We paid Time Warner shareholders $ 36,599 in AT&T stock and $ 42,100 in cash. Total consideration, including share-based payment arrangements and other adjustments totaled $ 79,358, excluding Time Warner’s net debt at acquisition. The fair values of the assets acquired and liabilities assumed were determined using the income, cost and market approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in ASC 820, other than cash and long-term debt acquired in the acquisition. The income approach was primarily used to value the intangible assets, consisting primarily of distribution network, released TV and film content, in-place advertising network, trade names, and franchises. The income approach estimates fair value for an asset based on the present value of cash flow projected to be generated by the asset. Projected cash flow is discounted at a required rate of return that reflects the relative risk of achieving the cash flow and the time value of money. The cost approach, which estimates value by determining the current cost of replacing an asset with another of equivalent economic utility, was used, as appropriate, for plant, property and equipment. The cost to replace a given asset reflects the estimated reproduction or replacement cost for the property, less an allowance for loss in value due to depreciation. Goodwill is calculated as the difference between the acquisition date fair value of the consideration transferred and the fair value of the net assets acquired, and represents the future economic benefits that we expect to achieve as a result of the acquisition. The following table summarizes the fair values of the Time Warner assets acquired and liabilities assumed and related deferred income taxes as of the acquisition date: Assets acquired Cash $ 1,889 Accounts receivable 9,020 All other current assets 2,913 Noncurrent inventory and theatrical film and television production costs 5,591 Property, plant and equipment 4,693 Intangible assets subject to amortization Distribution network 18,040 Released television and film content 10,806 Trademarks and trade names 18,081 Other 10,300 Investments and other assets 9,438 Goodwill 38,801 Total assets acquired 129,572 Liabilities assumed Current liabilities, excluding current portion of long-term debt 8,294 Debt maturing within one year 4,471 Long-term debt 18,394 Other noncurrent liabilities 19,054 Total liabilities assumed 50,213 Net assets acquired 79,359 Noncontrolling interest ( 1) Aggregate value of consideration paid $ 79,358 Purchased goodwill is not expected to be deductible for tax purposes. All of the goodwill was allocated to the WarnerMedia segment. Dispositions Hudson Yards In June 2019 2,081 and recorded a loss of $ 102 resulting from transaction costs (primarily real estate transfer taxes).

Finance Receivables Disclosure[Text Block]NOTE 9. SALES OF RECEIVABLES We have agreements with various third-party financial institutions pertaining to the sale 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) receivables related to our WarnerMedia business. 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 WarnerMedia programs are discussed in detail below. A summary of the receivables and accounts being serviced is as follows: June 30, 2019 December 31, 2018 Equipment Equipment Installment WarnerMedia Installment WarnerMedia Gross receivables: $ 4,519 $ 2,769 $ 5,994 $ - Balance sheet classification Accounts receivable Notes receivable 2,599 - 3,457 - Trade receivables 449 2,286 438 - Other Assets Noncurrent notes and trade receivables 1,471 483 2,099 - Outstanding portfolio of receivables derecognized from our consolidated balance sheets 9,528 3,725 9,065 - Cash proceeds received, net of remittances 1 7,073 3,725 6,508 - 1 Represents amounts to which financial institutions remain entitled, excluding the deferred purchase price. Equipment Installment Receivables 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 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 during the three and six months ended June 30, 2019 and 2018: Three months ended Six months ended June 30, June 30, 2019 2018 2019 2018 Gross receivables sold $ 2,244 $ 1,906 $ 4,945 $ 4,916 Net receivables sold 1 2,133 1,811 4,679 4,606 Cash proceeds received 1,920 1,532 4,195 3,927 Deferred purchase price recorded 261 307 570 826 Guarantee obligation recorded 93 72 194 195 1 Receivables net of allowance, imputed interest and equipment trade-in right guarantees.

At June 30, 2019 and December 31, 2018, our deferred purchase price receivable was $ 2,242 and $ 2,370, respectively, of which $ 1,531 1,448 454 and $ 439, respectively, of which $ 91 and $ 196 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. WarnerMedia Receivables In March 2019, we entered into a revolving agreement to transfer $ 1,400 of certain receivables from our WarnerMedia business to various financial institutions on a recurring basis in exchange for cash equal to the gross receivables transferred. As customers pay their balances, we transfer additional receivables into the program, resulting in our gross receivables sold exceeding net cash flow impacts. In June 2019, we expanded the program another $ 2,600 for a total maximum outstanding amount of $ 4,000, of which approximately $ 3,725 is outstanding at June 30, 2019. The transferred receivables are fully guaranteed by our subsidiary, which holds additional receivables in the amount of $ 2,769 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. Our maximum exposure to loss related to selling these receivables is limited to the amount outstanding. The following table sets forth a summary of WarnerMedia receivables sold during the three and six months ended June 30, 2019 and 2018: Three months ended Six months ended June 30, June 30, 2019 2018 2019 2018 Initial sale of receivables $ 2,325 $ - $ 3,725 $ - Collections reinvested under revolving agreement 2,127 - 2,127 - Gross receivables sold/cash proceeds received 4,452 - 5,852 - Net receivables sold 1 4,134 - 5,497 - Obligations recorded 384 - 436 - 1 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. As of June 30, 2019, our leases have remaining lease terms of 1 15 some of our leases include options to terminate the leases within one year Subsequent to the adoption of ASC 842 on January 1, 2019, 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 is updated on a quarterly basis for measurement of new lease obligations. The components of lease expense were as follows: Three months ended Six months ended June 30, 2019 June 30, 2019 Operating lease cost $ 1,610 $ 2,852 Finance lease cost: Amortization of right-of-use assets $ 70 $ 136 Interest on lease obligation 42 84 Total finance lease cost $ 112 $ 220 Supplemental balance sheet information related to leases is as follows: At June 30, 2019 Operating Leases Operating lease right-of-use assets $ 22,650 Accounts payable and accrued liabilities $ 3,344 Operating lease obligation 20,568 Total operating lease obligation $ 23,912 Finance Leases Property, plant and equipment, at cost $ 3,362 Accumulated depreciation and amortization ( 1,178) Property, plant and equipment, net $ 2,184 Current portion of long-term debt $ 137 Long-term debt 1,809 Total finance lease obligation $ 1,946 Weighted-Average Remaining Lease Term Operating leases 8.4 yrs Finance leases 10.7 yrs Weighted-Average Discount Rate Operating leases 4.7 % Finance leases 8.5 % Future minimum maturities of lease obligations are as follows: At June 30, 2019 Operating Finance Leases Leases Remainder of 2019 $ 2,250 $ 169 2020 4,276 296 2021 3,841 274 2022 3,561 264 2023 3,228 253 Thereafter 12,502 1,814 Total lease payments 29,658 3,070 Less imputed interest ( 5,746) ( 1,124) Total $ 23,912 $ 1,946

Accounting Policies [Abstract]
Leases [Policy Text Block]Leases As of January 1, 2019, we adopted, with modified retrospective The key change upon adoption of the standard was balance sheet recognition, given that the recognition of lease expense on our income statement is similar to our historical accounting. Using the modified retrospective transition method of adoption, we did not adjust the balance sheet for comparative periods but recorded a cumulative effect adjustment to retained earnings on January 1, 2019. We elected the package of practical expedients permitted under the transition guidance within the new standard, which, among other things, allowed us to carry forward our historical lease classification. We also elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment for land easements on existing agreements that were not accounted for as leases. We excluded all the leases with original terms of one year or less. Additionally, we elected to not separate lease and non-lease components for certain classes of assets in arrangements where we are the lessee and for certain classes of assets where we are the lessor. Our accounting for finance leases did not change from our prior accounting for capital leases. The adoption of ASC 842 resulted in the recognition of an operating lease liability of $ 22,121 20,960. The cumulative effect of the adoption to retained earnings was an increase of $ 316 reflecting the reclassification of deferred gains related to sale/leaseback transactions. We do not believe the standard will materially impact our future income statements or have a notable impact on our liquidity. The standard will have no impact on our debt-covenant compliance under our current agreements.

Spectrum Licenses [Policy Text Block]Spectrum Licenses in Mexico During the first quarter of 2019, in conjunction with the renewal process of certain spectrum licenses in Mexico, we reassessed the estimated economic lives and renewal assumptions for these licenses. As a result, we have changed the life of these licenses from indefinite to finite-lived. On January 1, 2019, we began amortizing our spectrum licenses in Mexico over their average remaining economic life of 25 years. This change in accounting does not materially impact our income statement.
Credit Loss Standard [Policy Text Block]Credit Loss Standard In June 2016, the FASB issued 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 current GAAP. ASU 2016-13 affects trade receivables, loans and other financial assets that are not subject to fair value through net income, as defined by the standard. The amendments under ASU 2016-13 will be effective for years beginning after December 15, 2019, and interim periods within those years. We are currently evaluating ASU 2016-13 but do not anticipate it will have a material impact on our financial statements.
