(f) Attestation Report of Independent Registered Public Accounting Firm
REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Shareholders of Virgin Media Inc. and subsidiaries
We have audited Virgin Media 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). Virgin Media 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 for Virgin Media
Inc.” 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, Virgin Media 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 sheets of Virgin Media Inc. and subsidiaries as of December 31, 2011
and 2010, and the related consolidated statements of operations, shareholders’ equity, and cash flows for each of
the three years in the period ended December 31, 2011 of Virgin Media Inc. and subsidiaries, and our report
dated February 21, 2012 expressed an unqualified opinion thereon.
