I want to quickly go over something on the innovation and the government's role in the economy. Thank you very much for this presentation. We'll wrap it up quickly.
When you talk about the best practice R and D ratio being three to one, private to public sector, and then I try to bring that back to government's role in the future, and I look at saying, okay, if we give the business regulatory certainty, then I wonder how long is their timeframe for decision-making if we give them regulatory certainty. But when you look at the track record, as is pointed out here, that R and D traditionally hasn't been very high and we're going to have an investment of $125 billion out to 2015, even given that regulatory environment, what's my confidence that business is going to move on the R and D to make this sustainable?
