About this Report

CVS Caremark’s 2010 Corporate social Responsibility (CSR) Report provides an overview of the company’s social and environ- mental commitments, and offers progress updates on the company’s CSR-publication of this type. We plan to continue reporting on an annual basis.

Global Reporting Initiative (GRI)

CVS Caremark recognizes the value of universally accepted standards for this type of voluntary reporting. The global Reporting Initiative (GRI), one of the most accepted frameworks in the world, served as a guide in determining content and performance metrics to include in the 2010 Report. We have provided an index of the GRI standard disclosures, including performance indicators, in this report. It can be found on the GRI Index page. Based on the criteria for GRI G3 guidelines and Application Levels, the 2010 CVS Caremark CSR Report meets requirements for Level C. More information on GRI is available at www.globalreporting.org.

Materiality Assessment

As part of this year’s reporting process, we commissioned a third party to help us identify and prioritize the company’s material issues.

The process for determining materiality involved gathering inputs from various internal and external sources, and then evaluating and prioritizing the issues found based on their relevance and importance to the company and significance to stakeholders. The sources used in this process included:

• Internal documents and plans that articulated the company’s business objectives and strategies, policies, programs and risk factors
• Communications prepared by the company for external release
• Feedback and insights from employees and customers
• Shareholder communications and any actions filed against the company
• Traditional media coverage
• Online and social media outlets
• Industry trade groups
• General trending issues of relevance

After reviewing these sources, we compiled a matrix of issues and prioritized each one based on the following criteria:

• The importance of the issue to and potential impact on CVS Caremark
• The importance of the issue to and potential impact on our stakeholders
• The amount of reasonable control CVS Caremark has over a particular issue

Based on the assessment and a review of the GRI guidelines, the material issues of greatest importance to CVS Caremark and its stakeholders, of which the company has a reasonable level of control over, fall into the following areas: corporate compliance, access to pharmacy care, management of the Company’s carbon footprint and meeting customer needs.

Reporting Year

CVS Caremark fiscal year 2010 (January 1, 2010 to December 31, 2010), unless otherwise noted.

Information Integrity

CVS Caremark management is responsible for the preparation and integrity of the information in this report. The metrics and goals in this report are established and measured by the groups responsible for achieving them. Through a system of internal controls, including a review process involving internal subject matter experts, we believe this report accurately and fairly represents our CSR activities, programs and results for the fiscal year ending December 31, 2010. The report was reviewed and approved by members of CVS Caremark senior management. However, this report has not been externally audited or verified by an independent third party, and at this time, the Company does not have a policy for external assurance of its CSR Report.
