Capability
Dispute and chargeback losses rarely rise because fraud rose. They rise because the same event enters twice, a provisional credit is never reversed, or a right to represent lapses unused.
Loss mechanisms
The dispute was decided in the institution's favour and the credit was never taken back, because reversal was a manual step with no exception report.
The same underlying transaction entered through two intake paths with no shared key, and both paid.
Network deadlines were tracked per case and never in aggregate, so eligible disputes expired unexercised.
Approach
| Question asked internally | Question the examination answers |
|---|---|
| Did dispute volume increase? | Which specific transactions were credited more than once? |
| Is our loss rate in line with peers? | Which credits remain outstanding against a decision that went the other way? |
| Are agents following the process? | Which eligible disputes expired before representment was filed? |
| What is the estimated impact? | What is the deterministic exposure by mechanism, with no overlap between totals? |
