Certainly, in terms of ERAPs, they are based on risk assessments. We do know the properties of petroleum, crude oil, liquid hydrocarbons...also have variations in it.
Obviously the ERAPs are approved by the regulator. Our expectation is that those risks would be looked into, and it's a good point whether they are separate or perhaps encompassed within the same ERAP, with possibly the idea that we're looking at the same types of resources and of the expertise required, whether it's, for example, packing group 2, packing group 1, or packing group 3 risk involved.
