How the radar works

Each item is classified by category, pinned to the jurisdictions it affects and scored from 0 to 10. The score starts from a model assessment of how serious the item is, then adds points for the kind of event, what it names and the source behind it. Reliability grades run from A1 (the regulator’s own notice) to C3 (a single secondary source).

AML News Radar reports what its sources publish. Summaries, categories and scores are automated; read the original notice before acting. It is not legal advice and not a screening decision.
