Report of Independent Registered Public Accounting Firm
The Board of Directors and Shareholders
Aflac Incorporated:
We have audited Aflac Incorporated's (the Company) internal control over financial reporting as of December 31,
2016, based on criteria established in
Internal Control - Integrated Framework (2013)
issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Aflac Incorporated's management is responsible for
maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control
over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial
Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on
our audit.
We conducted our audit 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
effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing
and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also
included performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles. A company's internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may
deteriorate.
In our opinion, Aflac Incorporated maintained, in all material respects, effective internal control over financial reporting
as of December 31, 2016, based on criteria established in
Internal Control - Integrated Framework (2013)
issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO).
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United
States), the consolidated balance sheets of Aflac Incorporated and subsidiaries as of December 31, 2016 and 2015, and
the related consolidated statements of earnings, comprehensive income (loss), shareholders' equity, and cash flows for
each of the years in the three-year period ended December 31, 2016, and our report dated February 24, 2017 expressed
an unqualified opinion on those consolidated financial statements.
