I would say those are the two main drivers of the variations. Then you will have the exceptional circumstances. For example, you will see some adjustments or payments if there are major floods or fires, emergencies, crisis situations. Those will also generate adjustments, and those are largely unpredictable. But the two main steady drivers, if I can put it that way, are really the budget and funds that are expiring in one year and then are either confirmed or not, or adjusted.
