I'll just add one thing to the government plan and the structure for the coverage for seniors. The way that copayment structure is modelled, so 30%, up to a maximum $25, I had spoken earlier about trying to encourage a maintenance supply of medications for use in chronic diseases. Really, if you look at that copay structure, it does really incent seniors to fill for a longer day supply, so a three-month supply, for example, instead of a one-month supply, because their copay is capped at $25 per prescription. That is a consideration. Certainly when we talk to our private plans, a lot of times they don't have a cap on their copayment structure. So, really, having a cap in that way does encourage, I think, the use of chronic medications being filled less frequently.
Certainly we do have plans on the private side that have 100% coverage, with no copays. We have plans that have fairly high copays. I would say that when it comes to the issue of compliance or adherence to medications, I think financial is one of the factors, but there's a number of other factors. Even on those plans that have 100% coverage for conditions like blood pressure or diabetes, where maybe you don't feel the effects of the disease itself, we still do see people not filling their prescriptions. Sometimes the side effects of those drugs are nasty and they're not feeling the effects of the disease.
