I don't know exactly how you construct those, but what I'll say is that we've done a number of pieces of essentially audit work that look at where you're investing, where you're investing in research, and the way different governments have invested.
For example, the team led a piece of work in 2001-02 looking at New Zealand's journey from Rio to Johannesburg. If you go online, you'll find it's called Creating our future: Sustainable development for New Zealand. That piece of work in fact laid out very clearly the differences in environmental sustainability thinking and investment among the different governments. We in fact have a table in there that actually shows the different approaches of the different administrations. So it's quite clear that we looked at the investment framework, not perhaps as strictly a value-for-money audit, but to see where the investment and the intent are going.
