I think that there are, quite frankly, a lot of complexities to how this is operationalized. As I said, I highlighted the pilot that is currently being undertaken in Ethiopia. It is the only pilot in the world being undertaken. So that gives you an indication as to how significant even the number of dollars dedicated to this style of aid are. It is in the early stage, so it is in effect experimental. It is an investment in innovation, and with any investment in innovation there is the possibility of failure. We think that is okay, particularly at a time when you're balancing that investment such that it isn't going to account for such a massive proportion of your aid envelope.
In terms of the specific question in terms of other sources of aid coming in from different donors, in this case the emphasis is on the result. So this contract of cash on delivery wouldn't necessarily meddle in with other donor contracts. That even being said, different donors engage in different ways, some through budgetary support, some through earmarked dollars for particular programs. It's up to the Ethiopian government to use the resources it has to achieve that particular result. I don't have the perfect answer to your question, but in this case it's trying out a new concept of a relationship between the donor and the partnered government.
