The market is also searching for clarity on further costs associated with the spill. But in an effort to help pay for those costs, BP already announced the sale of several global assets to Apache ( APA ) for $7 billion. With a divestment target already set at $10 billion, observers will also want hints on any future sales. BP's efforts to permanently plug the well hit a snag Friday when the company said it was halting drilling efforts on a relief well because of a coming tropical storm. Over the weekend, The Wall Street Journal reported that BP's board had negotiated the departure of embattled CEO Tony Hayward. Citing anonymous sources, the Journal said the board would meet Monday to decide on the departure plan, and that it was likely to appoint managing director Bob Dudley, who is also a BP board member, to succeed Hayward. Under the departure plan, Dudley would take the CEO's reins on Oct. 1, allowing for a two-month transition period, the Journal reported.
