The DAX (Deutscher Aktien IndeX) is a stock market index consisting of the 30 major German companies trading on the Frankfurt Stock Exchange. Prices are taken from the electronic Xetra trading system. According to Deutsche Boerse AG, the operator of Xetra, DAX measures the performance of the 30 largest German companies in terms of trading volume and market capitalisation. "After seven successful years in the M-DAX, we are pleased that we will soon be included among Germany's 30 largest listed companies, said Axel C. Heitmann, Chairman of the Board of Management of Lanxess AG. "This is a proud moment for us all and at the same time challenges us to continue to strive for profitable growth. My thanks go to all of our employees worldwide, without whose unremitting efforts we would not have come such a long way." "In the future, we will continue to focus on the emerging markets and on innovative premium products for the global megatrends of mobility, agriculture, urbanisation and water," Heitmann added. Lanxess was entered as an independent company in the Cologne commercial register on 28 January 2005. The stock was first listed for trading on 31 January 2005, and included in the stock index DAX for just one day to enable the DAX to be correctly computed. On that day the German blue-chip index comprised 31 companies for the first time in its history. Lanxess has transformed itself into a fast-growing speciality chemicals group. Today, the company has customers in a broad range of industries - from tyres, automotive, agriculture and construction to electrical/electronics and pharmaceuticals. A major focus is on high-performance rubbers for the production of fuel-efficient, energy-saving "green tyres. The company has steadily raised its profitability during the short period since its founding. The Group's EBITDA pre exceptionals nearly doubled from EUR 581 million in 2005 to EUR 1,146 million in 2011. Lanxess plans to achieve an operating result of EUR 1.4 billion in 2015. The company focuses on three segments comprising a total of 13 business units. Lanxess' strategy in recent years has been to grow both organically and through acquisitions. Annual sales of roughly EUR 1 billion have been added through acquisitions such as the Brazilian rubber producer Petroflex or the speciality rubber EPDM business of the Dutch company DSM. The company is steadily expanding the global production network for its portfolio of several thousand specialities. The most recent examples are three new plants in Asia: the new facilities for butyl and Nd-PBR rubbers in Singapore and the world's largest facility for synthetic EPDM rubber at Changzhou in the Chinese province of Jiangsu.
