We certainly have a relationship and exchanges with the Gates foundation. I think as recently as last week, Dr. Mundy was in dialogue with one of the specialists and technicians at the Gates foundation, so there is exchange of thinking and ideas.
The Gates foundation doesn't, at this stage, invest in education for development. The focus of their education work has been in the U.S. domestic education system, and of course they've been profoundly transformative in their investments and approach for AIDS and for vaccinations. The work that the Global Fund and Gavi do has been really transformed by Bill Gates and Melinda Gates becoming the kind of philanthropic donors and partners that they are today.
We do collaborate with both Gavi and the Global Fund because of this joined-up issue of health and education and everybody's increasing perceptions that we need to do more together. But there isn't co-operation with the Gates foundation on education for development directly, because the Gates foundation is currently not in the business of being a major donor or philanthropist or driver of change in the education for development space.
