Report of Independent Registered Accounting Firm
The Board of Directors and Stockholders of AT&T Inc.
We have audited the accompanying consolidated balance sheets of AT&T Inc. (the Company) as of December 31, 2015 and
2014, and the related consolidated statements of income, comprehensive income, changes in stockholders’ equity and cash
flows for each of the three years in the period ended December 31, 2015. These financial statements are the responsibility of
the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial
position of the Company at December 31, 2015 and 2014, and the consolidated results of its operations and its cash
flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted
accounting principles.
As described in Note 1 to the consolidated financial statements, the Company has elected to change its method of
accounting for customer set-up and installation costs for its video, broadband Internet and wireline voice services in 2015.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States),
the Company’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013
framework) and our report dated February 18, 2016 expressed an unqualified opinion thereon.
