We've been doing a number of things to try to continue to enhance the delivery of the scientific research and experimental development tax credit. In the last while, new money has gone into the hiring, for instance, of more scientists, because as you know, in determining whether an expenditure is eligible for the scientific research and experimental development tax credit, there's an element of science necessary to determine if it's eligible science, eligible research, and then of course there's the accounting side of it to determine the proper amount. We've beefed up our scientific capacity.
We've also done a number of things in the last year with additional money to improve the services to small businesses. There are 18,000 businesses that benefit from SR and ED in any given year, for a total tax expenditure of around $4 billion, but there has been a long-standing issue of making sure that in particular new businesses that are not necessarily thinking about taxes are aware of the availability of the program and receive the services they need.
