Piboonsak Soonpong, the family's lawyer, said the calculation was based on damage to the family's assets from 200406 plus interest of 7.5 per cent per annum. Some of the 600,000 share certificates belonging to the family were forged and sold by SCG employee Praphan Choomuang. Piboonsak said 90 per cent of the genuine certificates were sold through the market.
He said he may push the case to court if nobody shows responsibility for the damages.
SCG on Friday confirmed to more than 30,000 shareholders that the company will stringently investigate the forgery of share certificates and prevent the problem in the future.
Its president and CEO Kan Trakulhoon admitted that the fake certificates depressed investor confidence in the company's securities.
