We work through a three-year funding cycle, which allows us and the implementing countries to plan ahead. It's very important to be able to plan a national malaria plan over three years as opposed to one year. Every three years we have this replenishment conference where we expect all of our donors and partners to pledge, which means to commit to provide a certain amount for the following three years. It doesn't mean that the amount is paid at that particular moment, but the political commitment to pledge is made there, and then the payments usually happen every year for most of our donors.
