Awards published on TED (the EU’s Tenders Electronic Daily) often carry a framework ceiling rather than the amount spent, so for them we show the number of awards and the median contract size, never a total; a framework published on several lots counts as one contract. Totals cover only the awards published with a value. Each currency is shown on its own: amounts are never converted or added across currencies. Source: Tenders Electronic Daily (TED). Awards to individuals and sole traders are counted but never named.
