BP Adds to Stake in Russia, Despite Earlier Legal Battle
BP increases its stake in Russian oil company Sidanko to 25 percent from 10 percent; deal comes little more than two years after BP came close to scrapping its investment in Sidanco altogether during drawn-out legal battle over oil assets with two Russian companies that are now its partners in Sidanko; BP pays $375 million for 15 percent plus one share of Sidanko; transaction leaves BP's local partners, Alfa Group and Access/Renova with reduced, but still majority, stake (M)
