NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
Dollars in millions except per share amounts

NOTE 1. PREPARATION OF INTERIM FINANCIAL STATEMENTS
 
Basis of Presentation Throughout this document, AT&T Inc. is referred to as “we,” “AT&T” or the “Company.” The consolidated financial statements include the accounts of the Company and subsidiaries and affiliates which we control. AT&T is a holding company whose subsidiaries and affiliates operate worldwide in the telecommunications 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, 2022. 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 in our results on a one quarter lag. We also record our proportionate share of our equity method investees’ other comprehensive income (OCI) items, including translation adjustments.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions, including estimates of fair value, probable losses and expenses, 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. Unless otherwise noted, the information in Notes 1 through 12 refer only to our continuing operations and do not include discussion of balances or activity of WarnerMedia, Vrio, Xandr and Playdemic Ltd., which were part of discontinued operations.

Accounting Policies, Adopted and Pending Accounting Standards and Other Changes

Supplier Finance Obligations As of January 1, 2023, we adopted, with retrospective application, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2022-04, “Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations” (ASU 2022-04), which establishes interim and annual reporting disclosure requirements about a company’s supplier finance programs for its purchase of goods and services. Interim and annual requirements include disclosure of outstanding amounts under the obligations as of the end of the reporting period, and annual requirements include a rollforward of those obligations for the annual reporting period, as well as a description of payment and other key terms of the programs. The annual rollforward requirement becomes effective for annual periods beginning after December 15, 2023, with prospective application. In the year of adoption, the disclosure of payment and other key terms under the programs and outstanding balances under the obligations also applies to interim reporting dates.

For periods prior to repurchase, under 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), the ability to settle the Mobility preferred interests in stock was reflected in our diluted earnings per share calculation.

NOTE 4. SEGMENT INFORMATION
 
Our segments are comprised of strategic business units or other operations that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We have two reportable segments: Communications and Latin America.
 
We also evaluate segment and business unit performance based on EBITDA and/or EBITDA margin, which is defined as operating income excluding depreciation and amortization. EBITDA is used as part of our management reporting and we believe EBITDA to be a relevant and useful measurement to our investors as it measures the cash generation potential of our business units. EBITDA does not give effect to depreciation and amortization expenses incurred in operating income nor is it burdened by 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 revenue.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) - Continued
Dollars in millions except per share amounts

Effective for the first quarter of 2023, we stopped recording prior service credits to our individual business units or the corresponding charge to Corporate and Other, and segment operating expenses were recast to remove prior service credits from our historical reporting. Prior service credits are, and will continue to be, recorded as other income in our consolidated income statement in accordance with GAAP. This recast increased Communications segment operations and support expenses by approximately $2,400 for full-year 2022. Correspondingly, this recast lowered administrative expenses within Corporate and Other, with no change on a consolidated basis.

The Communications segment provides wireless and wireline telecom and broadband services to consumers located in the U.S. and businesses globally. Our business strategies reflect bundled product offerings that cut across product lines and utilize shared assets. This segment contains the following business units:
Mobility provides nationwide wireless service and equipment.
Business Wireline provides advanced ethernet-based fiber services, IP Voice and managed professional services, as well as traditional voice and data services and related equipment to business customers.
Consumer Wireline provides broadband services, including fiber connections that provide our multi-gig services to residential customers in select locations. Consumer Wireline also provides legacy telephony voice communication services.

The Latin America segment provides wireless services and equipment in Mexico.
 
Corporate and Other reconciles our segment results to consolidated operating income and income before income taxes.

Corporate includes:
DTV-related retained costs, which are costs previously allocated to the Video business that were retained after the transaction, net of reimbursements from DIRECTV under transition service agreements.
Parent administration support, which includes costs borne by AT&T where the business units do not influence decision making.
