Sales are generated primarily from the sale of goods and to a limited degree also include revenues from services rendered. Merck Group sales totaled € 9,905.9 million in 2011, which represents an increase of 10.9% compared to 2010. Adjusted for the impact of foreign exchange rates and acquisitions, primarily as a result of the Millipore acquisition, organic growth amounted to 4.8%. Sales are presented by business sector, division and region in the Segment Reporting (see Note [35]).
