Mr. Hong, I want to stay with you, actually, because I wanted you to just unpack these words for me if you could: natural capital accounting. You highlighted it in your opening statement, but can you unpack what that is? It does tie into what Mr. Elgie was talking about in terms of that greater integration of the economy and the environment.
I'm wondering about it both for me and for people at home. We're introducing—I think to a large number of people—some new concepts that need to be unpacked in terms of the definition and the intent. Can you provide that for us and maybe shed some light on it?
