That's a good question.
I'm not sure what the net figures would look like. We were looking at it more from a temporary service provision aspect, so you could go, for example, to Australia on a contract to provide a professional service for a fixed period of time. I don't know if there would necessarily be a net outflow. It would be on a temporary basis more so than a permanent one. It's a good question that I haven't seen an answer to.
