Maybe I can say two things.
First of all, yes, we are looking at this and doing a comparison of the last several years and post-May 2017, which you referred to. We are looking over time to see what's happened to acceptance rates, so certainly we'll look at that. It's going to take a little while because it is a manual process, and we don't store data by the underlying disease but about the impairment. That's what we look at.
The second thing I'll say is this is not a letter that indicates a policy change by the Minister of National Revenue. What's stated here is that there has been an evolution with respect to the therapy for diabetes. With devices like insulin pumps, it now takes less time to manage diabetes.
I absolutely stand behind this.
