CP All's board took no action against executive chairman Korsak Chairasmisak, vice chairmen Piyawat Titasattavorakul and Pittaya Jearavisitkul or True vice chairman-group counsel Athueck Asvanund for using insider information to buy Siam Makro shares just before CP All announced it would buy Makro shares above-market. The guilty quartet would have been motivated to seek a high purchase price that, in effect, transferred money from CP All shareholders’ pockets to those of Makro shareholders – including those of the inside traders’.
