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.
