Thank you for the question.
Perhaps I can pull out two specific risks that we sometimes see in our work, one that exists for the individual investor, and one that exists for government contracting in an imprecise way.
For the individual investors, there is and remains the consistent risk that an investment will be put in front of them that they feel is offering both social returns and financial returns, but in some sense it is masquerading on one or the other of those. I don't think that is a distinct or unique risk for investors, but it is something within the U.K. that many in the field are concerned about, making sure that there is integrity to the social investment opportunities out there.
For government, beyond some of the conversations that we've had today around the political dynamics being complicated, around whether this is making the state more effective or replacing the state, there are specific issues that we have seen around payment-by-results contracts separate from social impact bonds.
One of the risks we have seen in payment-by-results contracts or payment-by-outcomes contracts is that this government is very accurate with pricing, and often some of the most vulnerable people can be left behind, essentially because providers will take an economic decision that they are not being paid enough money to help those people out.
Part of our focus in the U.K. on social impact bonds has been seen as a response to that by saying that if you can have a broader range of providers, including mission-locked providers—charities, for example—they are much less likely not to help the hardest to help, but much more likely to help them. In some sense there is more of a partnership going on than just a straight...almost like a football match where one team wins, either the government or the providers they are with.
Those are two of the particular risks that we hear spoken about.
