Thank you.
The business case we build for such purchases covers multiple angles, and one of them is absolutely the risks associated with the transaction.
There are different transactions and there are different risks associated with those transactions. Of course there's the risk associated with the timing of it. There's also risk with the assumption that we make when we do the financial evaluation. As the transaction progresses, we know more information, more than estimation, so that makes it a bit more secure. There's also the assessment of the asset condition that is a risk when we do this kind of transaction. There's a financial risk with currency fluctuation as well because we're paying in U.S. dollars, so we want to take that into consideration. There's market availability, so that would be part of the risks in the option analysis and the business case we've put together.
