We haven't used a results-based funding mechanism in the sense of a pay-for-results kind of framework. As part of new ways of approaching international development, I think that's something we're exploring. We do know that our American counterparts do that and we're trying to learn from them and from the British and others.
Any time we do make a development investment, we want to make sure that the results are additional. If the results were going to materialize, and that's part of the evaluation going into the funding of a project, they do actually have to move the needle forward or avoid a deterioration of results. There has to be some kind of incremental impact before funding is allocated.
