Thank you for the question.
I wasn't there in May 2013, but I followed the file. It is now under my leadership that we continue working with CRA to have access to this kind of information, and not only that one. We also received another similar request back in November 2012. We are working on that. We're making progress with CRA. I'm not saying that it's easy, but we do make progress. We have openness with them. We have a good relationship. Do we have to be patient? Yes, we have to be patient with that.
Before I ask Mostafa to talk a little bit about the details of it, I would note that we developed another approach. We developed another methodology to look at these data with the kind of information we can receive from CRA. We're building bridges there. I will ask Mostafa to maybe talk a little bit more about the details of the procedure.
