No, we don't, but what I would say on the prescribing issue is—and this is in the paper that Frank referred to—that we do think we are not at the gold standard on prescribing practices in Canada. You can look at other prescribing guidelines and structures that have been put into place in other countries where they've made efforts, to your point, at getting at the root of the issue. Let's get our physicians prescribing appropriately and put some training incentive and process around that so that we can improve things. We'd be very supportive of that effort.
We, as an industry, become involved once the prescription has been presented at the pharmacy. That's when our interest directly starts, but we acknowledge that there are issues upstream in the system that could certainly be improved, and it could have benefits for us if we do better as well.
