Thank you very much, Madam Chair.
Mr. Vigneault and Ms. Henderson, thank you very much for being with us.
Ms. Henderson, I'd like to go back to you to talk a little about these issues management notes, or IMUs.
Could you continue with your response—to Mr. Calkins, I believe—in terms of how the IMUs work? I'm going to ask a couple of questions. How do they work? Who is on the distribution list? Can you give me, not who specifically, but a vague number of how many agencies, departments or people are on that list?
