MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
The management of Halliburton Company is responsible for establishing and maintaining
adequate internal control over financial reporting as defined in the Securities Exchange Act Rule 13a-15(f).
Internal control over financial reporting, no matter how well designed, has inherent limitations.
Therefore, even those systems determined to be effective can provide only reasonable assurance with
respect to financial statement preparation and presentation. Further, because of changes in conditions, the
effectiveness of internal control over financial reporting may vary over time.
Under the supervision and with the participation of our management, including our chief executive
officer and chief financial officer, we conducted an evaluation to assess the effectiveness of our internal
control over financial reporting as of December 31, 2011 based upon criteria set forth in the Internal
Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission. Based on our assessment, we believe that, as of December 31, 2011, our internal control over
financial reporting is effective.
The effectiveness of Halliburton’ s internal control over financial reporting as of December 31,
2011 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their
report that is included herein.
