Thai Bourse Adjusts SET50 And SET100 Index Lists

Date 07/12/2005

The Stock Exchange of Thailand (SET) announced its adjustment to the SET50 and SET100 securities effective from December 8, 2005 onwards.

Since the soon-to-delist National Petrochemical Pcl. (NPC) and Thai Olefins Pcl. (TOC) are currently included in the SET50 and SET100 indexes for the 2H/2005 (from July 1 – Dec. 31, 2005), there will be adjustments in both index lists as follows:

SET50 Index list:

Tisco Bank Pcl. (TISCO) and TT&T Pcl. (TT&T) will replace NPC and TOC.

SET100 Index list:

Syntec Construction Pcl. (SYNTEC) and KCE Electronics Pcl. (KCE) will replace NPC and TOC.

National Petrochemical Pcl. (NPC) and Thai Olefins Pcl. (TOC) will be merged to become PTT Chemical Pcl. (PTTCH). Therefore it is expected that PTTCH will again be considered for inclusion in the SET50 and SET100 indexes after it has begun trading on the Thai bourse.
