RAO Unified Energy System of Russia (EESR.RS), or UES, Friday said it had asked its board to approve June 6 as the day to halt trading in its stock.
Shareholders as of that date would receive proportionate stakes in the companies being spun off from UES as part of a massive restructuring program organized by the government.
Those who buy shares in UES after this date would only get a stake in the Federal Grid company, or FSK, which will remain under state control after electricity sector reform is complete and UES ceases to exist at the start of July.
UES' board will meet March 28 to decide the issue.
