Lesar, president and chief operating officer of Halliburton who will continue in such role, said, " We know each other's business well and have agreed on the organizational structure, which will facilitate a quick, smooth integration. With our combined financial strength and complementary capabilities, the combined company will also have the resources to significantly increase investments in state-of-the-art technology while making targeted acquisitions to further add to our capabilities. In addition, with the revenue enhancements and cost reductions we will get from integrating these broad capabilities, we expect the transaction to be accretive to earnings per share in the first full year, after an expected one-time charge to consolidate the businesses."
