STATEMENT OF MANAGEMENT RESPONSIBILITY FOR FINANCIAL STATEMENTS

The management of Quest Diagnostics Incorporated is responsible for the preparation, presentation and integrity of the consolidated financial statements and other information included in this annual report. The financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and include certain amounts based on management’s best estimates and judgments.

Quest Diagnostics maintains a comprehensive system of internal controls designed to provide reasonable assurance as to the reliability of the financial statements as well as to safeguard assets from unauthorized use or disposition. The system is reinforced by written policies, selection and training of highly competent financial personnel, appropriate division of responsibilities and a program of internal audits.

The Audit and Finance Committee of the Board of Directors is responsible for reviewing and monitoring Quest Diagnostics’ financial reporting and accounting practices and the annual appointment of the independent auditors. The Audit and Finance Committee meets periodically with management, the internal auditors and the independent auditors to review and assess the activities of each. Both the independent auditors and the internal auditors meet with the Audit and Finance Committee, without management present, to review the results of their audits.

The consolidated financial statements have been audited by our independent auditors, PricewaterhouseCoopers LLP. Their responsibility is to express an opinion with respect to the consolidated financial statements on the basis of an audit conducted in accordance with auditing standards generally accepted in the United States of America.
