NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation Throughout this document, AT&T Inc. is referred to as “AT&T,” “we” or the “Company.” The consolidated financial statements include the accounts of the Company and our majority-owned subsidiaries and affiliates. Our subsidiaries and affiliates operate in the communications services industry both domestically and internationally, providing wireless communications services, traditional wireline voice services, data/broadband and Internet services, video services, telecommunications equipment, managed networking and wholesale services.
All significant intercompany transactions are eliminated in the consolidation process. Investments in partnerships and less than majority-owned subsidiaries where we have significant influence are accounted for under the equity method. Earnings from certain foreign equity investments accounted for using the equity method are included for periods ended within up to one month of our year end (see Note 8). We also record our proportionate share of our equity method investees' other comprehensive income (OCI) items, including actuarial gains and losses on pension and other postretirement benefit obligations.
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 amounts have been reclassified to conform to the current period's presentation.
