Russian electricity producer OGK-2 may hold another share sale or a bond offering after failing to raise the $1.7 billion it had sought via a London float, the CEO of its parent company said Tuesday. The most recent share sale will provide cash enough for at least a year, after which another offering of shares or convertible bonds would be possible, said Anatoly Chubais, CEO of former power monopoly Unified Energy System (UES). Chubais also said on Tuesday OGK-2`s secondary share offering was not completed, contradicting OGK-2`s statements Friday and Monday that the book on the deal was closed. On Friday OGK-2 slashed the size of its share placement by more than half after natural gas monopoly Gazprom purchased the bulk of the shares for $0.16 each, at the lower end of the price range. The natural gas monopoly, which owned 54 percent of OGK-2 before its share issue, thus paid $640 million to maintain control. Analysts said Gazprom`s move may have scared away other investors. OGK-2 said in its Monday statement that it will not raise more than $1.1 billion in its share offering, well short of the amount needed to fund its $1.7 billion investment program.
