Attestation Report of the Independent Registered Public Accounting Firm
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of
Dollar Thrifty Automotive Group, Inc.:
We have audited Dollar Thrifty Automotive Group, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2011, based on criteria
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO
criteria). Dollar Thrifty Automotive Group, Inc. and subsidiaries’ 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, testing
and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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, Dollar Thrifty Automotive Group, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting
as of December 31, 2011, based on the COSO criteria .
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of
Dollar Thrifty Automotive Group, Inc. and subsidiaries as of December 31, 2011, and the related consolidated statements of income, stockholders’ equity and
comprehensive income, and cash flows for the year ended December 31, 2011 and our report dated February 28, 2012 expressed an unqualified opinion
thereon.
