In BP, in concert with the entire industry, our first focus is on prevention, so that is preventing any incidents from taking place. Clearly, in this instance the fail-safe device, the blowout preventer, did not work.
Our second response is one of spill response and cleanup. With regard to the Arctic, I think it's very important that we wait for the study and for the investigations to complete and as an industry take the results and findings from those investigations into the review of the same-season relief well policy.
