The obligation to submit retroactive declarations for a 3-year period is set out in article 2.1. of the Regulations to the Bebat Participation Agreement. This time period starts on 1 January of the third year that precedes the affiliation year. Bebat has decided to put this in place in order to create a level playing field, i.e. fair competition between all participants. There are a lot of participants who have been a Bebat participant for years and who have paid the applicable  environmental or administrative contributions. As such, it is no more than fair that companies who are only just affiliated even though they have been selling batteries for longer than today, should also pay their dues for the past. However, Bebat has decided to confine this to a 3-year period.
