As the official award notices state them, over the last 3 years. Tenders per lot count open and restricted procedures only: in a negotiated procedure or a direct award a single tender is the procedure itself. The country is the one the notice gives for the winner.
One dot per award, on the day it was signed, sized by its value. A ring is an award with no published value.
