#What we detect

A multiplier decrease matching a standing ReverseSplit record whose unit ratio reconciles.

#Evidence required

• A standing record matching both multipliers and the activation time.
• The unit ratio reconciles with the multipliers.

#When evidence is missing or conflicts

• A ratio that does not reconcile: unclassified.
• The same ratio is not enough on its own. AZNx halved its multiplier exactly like HONx did, and was an identity change; the issuer record decides.

#How it is booked

Units ×factor. The protected floor ×factor. Zero income.

#In practice

HONx, 2:1.

#In the API
