North ASEAN Country Group As of
January 1, 2004, the ASEAN country group is divided into two groups: North and South ASEAN.
Thailand, Vietnam, Myanmar, Laos and Cambodia form the North ASEAN country group. The single
largest market in this country group is Thailand which also plays a key role in the expansion of
the company's regional manufacturing base in Asia Pacific. The total investment for building up a
world-scale production site for plastics in Map Ta Phut, on the eastern seaboard of Thailand, is
about EUR 400 million. Against the background of growing demand for its polycarbonate thermoplastic
Makrolon®, Bayer is building up the Map Ta Phut site in Thailand into a regional production base as
part of the worldwide production network.
