Lead and zinc smelter OTZK will replace mineral extracting company Kaolin in the BG 40 index of the local stock exchange, the bourse operator said.
The change will become effective as of November 27, the Bulgarian Stock Exchange (BSE) said in a statement posted on its website after the end of trading hours.
Earlier this month German minerals extracting and processing company Quarzwerke launched a squeeze-out for 1.75% of Kaolin. Quarzwerke bought some 87% of Kaolin from Bulgaria's Alfa Finance Holding in May and later increased its stake in the company.
BG 40 is a price index that tracks 40 issues of common shares with the greatest number of transactions and the highest median value of the daily turnover during the last six months.
