American oil and gas company Occidental Petroleum has sent a proposal to purchase a 100% stake at $76 per share to the board of directors of the American company Anadarko, specializing in the exploration and production of oil and natural gas. The offer made earlier by the American Chevron for the purchase of Anadarko assumed payment of $65 for each of its shares. The terms of the deal proposed by Occidental Petroleum are more beneficial for Anadarko, according to a letter sent to its board of directors. Occidental Petroleum intends to pay 50% in cash and the remaining 50% - in shares. Its valuation of the transaction is 57 billion dollars. The implementation of the transaction will provide an opportunity to create a world leader in the energy sector.
