I'll talk quickly at three levels.
At the first level, which is people paying voluntarily in the first place, I'll look back to last fall's “Fiscal Monitor”. In the November report, they showed that multinationals paid 7.5% more tax in the six months ending November 2017 than they did previously. The economy grew at 3%, so they paid 4.5% more corporate tax than the economic growth would seem to suggest. Non-residents paid roughly 20% more tax in the similar period. Strategically, I think there's some sense that the people we're targeting are getting the message, and they're starting to do the right thing.
Now, with the second level, the audit yield, what we identified through audit, there was an expectation that we'd find $380 million in fiscal 2016-17. We found $500 million. This fiscal year, which is going to close in a couple of weeks, we expected just over $1.1 billion. We had hit that by the third quarter. In terms of the immediate revenue generation, we expect that to be exceeded again this fiscal year.
In terms of the right taxpayers, that's where we talk about people with offshore money. We talk about 40 criminal investigations in terms of offshore, and over 1,000 audits of individuals who had money offshore. Now, we have been talking about audits and not results yet, because those are complicated audits. We have taxpayers who are refusing to be audited. We have a number of cases before the courts where the taxpayers aren't co-operating with us. It will be a number of years for those criminal investigations to be finalized and the audits to be finalized.
I would say that at the level of strategic voluntary payment with the revenue generation we committed to and the target action on offshore, we have a track record of results.
