The final point I wanted to make was on the scientific research and experimental development tax credit program.
Mr. Hoffman, in your presentation you referenced it. Mr. Boitson and Mr. McKay, you talked about it earlier this afternoon.
The general reaction we get is that it's a good program, it's one of the most generous R and D tax credits in the world, but we do get recommendations on changing it, i.e. making it at least partially refundable. So a very quick question again: would you recommend changes to that program?
