There is no question. For anything that is a driver of research, obviously, it will take time, first of all, to generate the discoveries, and second, to allow the discoveries to move into the marketplace in terms of new products and processes.
If I may just step back quickly to the accelerated writeoffs for manufacturing equipment, I think if the government chose to extend the temporary writeoff for a longer term, the impact would be more than incremental. I think the major criticism that has been made of that particular initiative is that when you're talking about making major investments, given the planning times, the environmental approval times, the regulatory and the investment cycles, it is very difficult to actually get investments in place within the two-year timeframe. I think, therefore, that if it's limited, and stays limited, to two years, the take-up may be smaller than predicted.
I think extending it would simply make it possible to use it.
