The agreement also stated a period of transition for the Baltic countries to last until December 31, 1999. This was a much shorter period than that which was assigned to the Central European countries (their transition periods were declared to be 10 years). Estonia declined the transition period, Latvia received a transition period of four years, and Lithuania received a transition period of six years.
their transition periods were declared to be 10 years and 10 months
