Thank you. That's a very good question.
I'll reply in English.
We did think about this carefully. The reason for deciding on the second anniversary is that the results of the system will not be clear for about a year and a half. The reason is that the system has two components, with a charge and the output-based pricing system. The charge will be paid on a regular basis, once it's imposed and comes into force. By contrast, the output-based pricing system is paid on an annual basis at the end of each year. The carbon pricing backstop system will come into force on January 1, 2019, about half a year from now, and then for the first year, the obligation of a large facility subject to that system will be to track emissions. At the end of that year—so in the winter of 2020—it will then report its emissions, calculate how much it owes, and then pay what it owes, if it owes anything. The payment it makes will not be made until the middle of 2020, so in other words, we will not know precisely who has paid what under the system until the middle of 2020. It's for that reason that we decided that the first report should be a complete report and talk about where the system was applied, in what jurisdictions it applied, how much charge was paid, by whom, and how much of the output-based pricing system charges were paid and by whom. Again, we won't have all of that information in place because all of those activities will not have occurred until about the middle of 2020. That's why we picked two years, but then the obligation is an annual report thereafter.
