The best study that was done during the negotiations was by Professor Aidan Hollis, in Calgary, and Paul Grootendorst, at the University of Toronto. Their estimate was that for the full range of commitments that the Europeans were demanding at that time, the cost could be up to $2.8 billion per year. As I said in my presentation, the government did not agree to all those demands. There were lesser demands. There was no increase in data protection, only a two-year patent extension, so clearly the costs will be less than that.
I will give you a number, but the other qualifier I would put on it is that we're looking into the future, probably eight or ten years, before the costs come into play. It really depends on what products come on the market during that time as to what the actual costs would be.
Having said all that, if we simply take their estimate and use two years instead of the extra years that were being asked for, it could be somewhere in the range of close to $1 billion extra per year in the future.
