Mr. Chair, through you to the officials, this raises two questions. Of course, the intent of our amendment is precautionary, in keeping with the precautionary principle, rather than after the fact, after this disaster occurs, and then you're trying to assess liability. This is talking about giving consideration to the level of risk of unconventional projects.
The question for the officials, through you, Mr. Chair, is that when we think about severely risky projects, such as drilling in the Arctic, how did you come up with a figure of $1 billion?
