We recognize that to report effectively on our performance on corporate responsibility-related issues, we have to measure performance and progress on numerous metrics and parameters. For some topics we have been measuring performance for many years, while other metrics are new for us. We continue to review and refine our metrics so that we can focus on what is most meaningful to inform our business decisions and what matters most to our stakeholders.

This section contains data summaries and other resources on our CR performance globally:

• Merck's corporate responsibility key performance indicators
• Summary of disclosures of Merck performance according to Global Reporting Initiative indicators
• Summary of Merck performance according to the Access to Medicines Index
• Summary of Merck contributions to achieving Millennium Development Goals
• Summary of Merck progress against the 10 principles of the Global Compact

We regularly review our data to ensure accuracy and consistency.  In some cases, for example on selected environmental metrics, this has led to slight changes in the statistics for prior years.
