Glencore exchanges shares of the aluminum company for En+ securities.
The oligarchs sold a 3% stake in Rusal which could complicate the IPO of Deripaska's En+ in December.
The deal was conducted with a discount of 7.5% from the market price of these securities.
Strengthening of the ruble by 7%, the risks of volatility in aluminum prices and changes in the electricity and capacity market: these are the objective risks for Deripaska's companies.
