Thank you for the question.
It's too early to say. The first social impact bond in the U.K. was set up—if we're just talking about social impact bonds—in 2012. The fair chance fund and the youth engagement fund were both set up within the last nine months, so they're just getting going.
All the early indications from the social impact bonds are that they are achieving better outcomes than the counterfactual, what would have happened anyway. What we don't know yet is whether that is something that would happen if it were replicated wider or whether this is some sort of pilot halo effect because there's a degree of attention and focus upon them.
In a way I've broadened out to say what is happening around accessing investment and private investment. Quite frankly, I'd look at the hundreds of millions of pounds now that have come into the social sector that would probably not have come into the social sector anyway, and I would look to the testament of social sector organizations who are saying that access to this sort of capital, not being dependent upon declining government grants or very expensive fundraising, has allowed us to free up the time and go out and do what we do best, which is tackle social issues.
