Well, as you say, there was some research—an independent study, in fact—in 2014, which concluded that, on average, the fund generates a benefit of £3 for every £1 spent on that scheme. A frequent question, as Nick Ramsay says, is why good practice just doesn't seem to spread very easily, and this is something that we're working on with Cardiff University. We're researching the barriers, and also the enablers, for the spread of the good practice that we've learned through the innovate-to-save scheme. The evidence-gathering stage of that will be completed by 30 June, and then there will be the analysis of the findings throughout the summer. We've secured £4,000 of research funding in Cardiff University, which can be used to support events with academics and practitioners across Wales to discuss our findings and to highlight the benefits that we've been able to accrue through the invest-to-save scheme, and to try and ensure that those benefits are spread more widely.
