HONG KONG, Feb 20 (Reuters) – Russian aluminium giant Rusal said on Tuesday there had been no changes to the roles of chief executive officer (CEO) or president at the company, although a board meeting would be held on Thursday to consider executive changes. Russian billionaire Oleg Deripaska plans to step down as president of the two companies he controls – Rusal and En+ Group , two sources familiar with the matter told Reuters.  “As at the date of this announcement, the board of directors of the company has not considered or discussed any such issue,” Rusal said in a filing to the Hong Kong bourse, responding to media reports suggesting executive changes. A board meeting is scheduled for Feb. 22 to consider executive changes, the company said. It gave no further details. Reports of a management re-shuffle first appeared in Russia’s Kommersant newspaper. Maxim Sokov, En+ current chief executive officer, would become En+’s president, Kommersant said. Vladislav Soloviev, Rusal CEO, would become CEO of En+ and president of Rusal, while Rusal’s current chief financial officer, Alexandra Bouriko, would be appointed Rusal CEO, one of Reuters’ sources said.
