A similar question was asked when both Mr. Caron and I appeared before the Senate a couple of days ago. The key message I want to transmit here, using blowout preventer as an example of what we're talking about, is that we're looking for redundancy, we're looking for reliability, and we're looking for capability. Where we have the possible identification of hazards, we would look at all these aspects and at what we're going to be doing regarding those hazards. When that's the case, we look at these three aspects. Are they adequately covered? Only when we're satisfied can we move forward.
