I think the duration of a licence is reasonably generous. It's two years with a two-year renewal, so it's actually a four-year licence. I think part of the rationale behind that is this. If prices drop, if new technology comes on that's a little better, do you really want to tie governments into unending contracts without a way out? I just think there's probably a process that needs to be in place that respects the legislation that's been passed.
