Perhaps I could speak to that.
As I mentioned earlier, when we put this together, the evaluations of the systems were being done en totale. In the past, the evaluations have been done independently. So what's happened at the agency is that we've created an entire framework for evaluation of all the systems, a framework that is in place now, and we're going to be doing a number of the individual evaluations over the next few months of the evaluation. So it's coming into place now. It's been a little bit delayed on the planning, because it was done for all of them at the same time and not independently.
