Madame Chair, I may be sharing my time with my colleague here.
I think my colleague covered what's going on in other countries.
One of my constituents called me this week and asked me why we don't issue them for ten years as opposed to five years. I told him I thought it's probably for security reasons, and maybe because security improves over a period of time and you wouldn't want to issue them for too long, but I told her I would check with you to see whether that's the reason, or whether it's just for us to make more money.
