It's a timing issue. When we do the plan, we base it on the projects that are approved based on what we know. As the year evolves, new projects get approved, new realities. Some projects materialize, others don't materialize, and then we seek supplementary estimates based on developments over the course of the year that were either not defined at the beginning of the year or unforeseen. This is why you can't compare from when we planned to the end of the year. Things happen.
