That varies pretty strongly by the specific issue. For any social impact bond, when we think of the economic implications of the outcomes that are produced, there's an understanding that the value of those outcomes will very much be divided between government and the private investors that have forwarded the capital.
In cases where there is a very cost-effective intervention—something that can produce very strong outcomes for very little upfront capital—the returns are inherently higher, and vice versa. However, to be a bit more specific, we've seen broadly a sense of tolerance and understanding that it's anywhere between 5% to around 12%. That is the general understanding.
