You're right that the utilization of generics in the private plans is lower. As you said, I think the benefit of generics is what we often refer to as headroom. If you save on the cost of older medications by using generics, you can then better afford the cost of some of the new medications. That's clearly what a lot of the programs do.
In Canada, we have a universal heath care system. Most employees are covered. If they're sick and they go to see a doctor, or if they have to go to the hospital, those costs are covered. If we compare that to the United States, those costs aren't covered. Often, the employee drug plans are part of a larger health care plan in the U.S. and much more expensive. I think, frankly, what we've seen is a more aggressive health management operation in the United States in the private plans. In Canada, some of the plans are not generic-only plans. In the public plan in Ontario, if a doctor writes “Lipitor”, and Lipitor is a genericized product, in all likelihood, the patient will get the generic atorvastatin at 18% of the cost, so they can fill five or six prescriptions. In many private plans, if Lipitor is prescribed, they pay for Lipitor, and simply don't require the generic. I think some of the private plans need to become more rigorous in enforcing generic-only plans.
