I guess can we just start by getting an explanation of the $70 million we see here for asset retirement obligations. I have a general sense that this is under the new P3 accounting standards. So I guess I'd like to get a sense of whether this is a one-time figure we will now just carry on our books as a debt, or whether this is a thing we will kind of expect to see in future capital budgets and how exactly that works financially. Thank you, Madam Chair.
