We have actually tried to do comparisons of the staffing processes and we tend to use, as a proxy, time to staff. So we will do comparisons on time to staff, and that gives an indication of how long it costs. That's not been terribly successful. The reason for that is there are a lot of differences, even though we're Commonwealth countries, that make it not a meaningful comparison.
