In her announcement, she made it clear that:
- She believes the time is right for her to abdicate
- This year is the 200th year of the anniversary of The Netherlands becoming a monarchy.
- She's not abdicating because she no longer thinks she can handle the position or is tired.
- She believes it's time for a new generation to lead and that Williem-Alexander & Maxmia will be good for the monarchy.
