OMPD Annual report- 14 months from day of COMP positive opinion or from EC decision

As the title suggests, I am wondering from which day to start counting the 14 months until OMPD annual report submission. Is it 14 months from day of COMP positive opinion or from receiving EC decision/ day noted on EC letter.
 

Annual reports for orphan medicinal products designated by the EU should be submitted within 2 months following the anniversary of the grant of the designation, meaning the EC decision.
