Also, the Committee evaluates the performance of the Company's internal audit function.

The Committee's role is one of oversight and review. It is not expected to audit the Company, to define the scope of the audit, to control the Company's accounting practices, or to define the standards to be used in preparation of the Company's financial statements.


The Committee shall perform the following functions in the following areas:

The Committee also shall review with the independent auditors their report on the audit and review with the Company's officers the independent auditors' suggested changes or improvements in the Company's accounting practices or controls.

The Committee shall review with the Company's officers recommended changes in the Company's methods of accounting or financial statements.

Where appropriate, consultation with the independent auditors regarding internal controls shall be conducted out of the presence of the Company's officers.
  6. Financial Disclosure Documents. Review with the Company's officers and the independent auditors the Company's financial disclosure documents including all interim and annual financial statements and reports filed with the Securities and Exchange Commission or sent to stockholders and interested parties and, following the satisfactory completion of each year-end review, recommend to the Board the inclusion of the audited financial statements in the Company's annual report on Form 10-K. The Committee shall discuss with the Company's officers the type and presentation of information to be included in the Company's earnings press releases (paying particular attention to any use of "pro forma" or "adjusted" non-GAAP information), as well as financial information and earnings guidance provided to analysts and rating agencies. The review shall include any significant problems and material disputes between the Company's officers and the independent auditors and a discussion with the independent auditors out of the presence of the Company's officers of the quality of the Company's accounting principles as applied in its financial reporting and tax provision calculations, the clarity of the Company's financial disclosures and degree of aggressiveness or conservatism of the Company's accounting principles and underlying estimates, and a frank and open discussion of other significant decisions made by the Company's officers in preparing the financial disclosure and reviewed by the independent auditors.
  7. Risk Management. Review whether Company officers have in place a current and comprehensive enterprise risk management framework and associated procedures for effective identification and management of the Company's business and financial risks, including fraud. Assess the impact of the Company's enterprise risk management framework on its control environment and insurance arrangements. Determine whether a sound and effective approach has been followed in establishing the Company's business continuity planning arrangements, including whether business continuity and disaster recovery plans have been periodically updated and tested. Ensure all major strategic and operational risks are brought to the attention of the Committee in a timely manner and monitor and report on the management of major strategic and operational risk. Periodically review the Company's information technology strategy and provide oversight for all matters related to information technology systems and procedures, including data privacy and security.

The review shall include internal audit summaries of and, as appropriate, copies of its significant reports to the Company's officers and the officers' responses, as well as any significant problems and regulatory concerns.
  9. Ethical Environment. Consult with the Company's officers on the establishment and maintenance of an environment that promotes ethical behavior, including the establishment, communication, and enforcement of codes of conduct to guard against dishonest, unethical, or illegal activities. The Committee shall establish procedures for the receipt, retention, and treatment of complaints received by the Company from its employees regarding accounting, internal accounting controls, and auditing matters, and the confidential, anonymous submission by employees of concerns regarding questionable accounting or auditing matters.
  10. Oversight of Independent Auditors.
