There are two different systems: one for the retail pharmacy pricing and the other for the hospital pricing. With hospital pricing, prices are determined essentially by a tendering system and negotiations with the large buyers and other health care suppliers such as HealthPRO. That is a true marketplace price as a result of that bidding, and we've had several comments about whether there are several suppliers or whether it's just winner take all. So in the hospital market, it's a tendering system.
In the retail market, generic drug prices are subject to provincial regulation. For example, the government in Ontario has changed the regulation on generic pricing twice in the last five years. Starting in April, if you want to be listed on the Ontario formulary, you can charge no more than 25% of the equivalent brand-name product. They have some rules for exceptions if costs are higher. Pricing is set by provincial regulation. Ontario tends to be the leader. Quebec has a rule they call “the best available price rule”. Quebec will not pay any more than any other province. Then you go across the country with various pricing systems.
For the manufacturers who are trying to sell nationally, it tends to be a complicated system. It's like dealing with 10 different countries. But generic drug prices are regulated provincially.
