Notes to the segment reporting Audited by KPMG

The classification of asset and income figures as well as of other key figures by business sector or by region in accordance with IAS 14 is presented in “Segment Reporting”. Segmentation was performed in accordance with the internal reporting of the Merck Group. The financial result and taxes on income are allocated in full in the Corporate and Other segment. The operating segments are described in detail in the chapter about the divisions in this Annual Report.

With the sale of our Electronic Chemicals business in April 2005, we reclassified the remaining contract manufacture business as well as the figures reported under this segment to the segment “Corporate and Other”.

Transfer prices for intragroup sales are determined on an arm’s-length basis. There were no significant intercompany relations between the business segments. In the Segment Reporting, the United States and Canada are combined to form a single region “North America”, as the two countries are managed as a single territory in the Merck Group’s internal reporting.

Operating assets included in “Segment Reporting” were as follows:
