How do I read the risk rating and the review flags?

The rating is calculated by fixed rules from the severity of the individual findings, so the same findings always produce the same rating. The highest-severity finding sets the band and the others add points within it. A report with no risk-bearing findings reads None identified.

The score bands are:

Each check carries one of these results:

A manual review flag is raised when the subject could not be matched with certainty (to a register record, or for a ship by its IMO number), when any finding is critical, when a sanctions or owner screen could not be completed, or when sanctioned owners hold stakes that are unknown or below the 50% control threshold. A review flag never lowers the rating.
