Originally scheduled for just five years, steps were then taken to extend the milk quota system until 1992. The Reform of the CAP in 1992 (MacSharry Reform) led to a further prolongation of the quota system until 2000, at which point, as part of Agenda 2000, the system was further extended until 2008. Finally with the Luxembourg Agreement on the MTR in 2003, MS approved another extension of the quota regime until 2015. The extension under the MTR is notable since, in contrast to previous situations, MS must actively advocate a prolongation of the quota regime beyond 2015, otherwise it.
