I'm not sure I totally understand the question, but maybe I can just answer it this way.
The energy east pipeline is a vehicle where western Canada landlocked crude-based systems can access global markets, so if the Keystone XL pipeline is disallowed, then the energy east pipeline becomes one of the major conduits to get crude and crude bitumen out to market.
Our assumptions with regard to increased oil sands production, especially anything above that four million barrel level, is predicated on one or two of the pipelines being authorized. The energy east pipeline is definitely one of the major pipelines that would allow sustained oil sands growth to feed that pipeline.
