Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal patterns at play. Has this 15% drop been compared to the same quarter last year?

Why it matters: Seasonal variations could explain the drop and inform our approach. Expected answer: Yes, it has been compared, and the drop is still significant. Impact on approach: If seasonal, we'd focus on adjusting algorithms for cyclical patterns.

• Considering the metric itself, I'm curious about the definition. Has there been any recent change in how fraud detection rates are calculated or measured?

Why it matters: Changes in measurement could artificially create a drop in performance. Expected answer: No changes in calculation methods have been made. Impact on approach: If changed, we'd need to standardize metrics before further analysis.

• Thinking about user segments, I'm wondering if this drop is uniform across all customer types. Are there specific segments more affected than others?

Why it matters: Segmentation could reveal targeted issues or vulnerabilities. Expected answer: The drop is more pronounced in certain customer segments. Impact on approach: We'd prioritize investigating and addressing issues in the most affected segments.

• Reflecting on recent updates, have there been any significant changes to the ACI Fraud Management solution in the past quarter?

Why it matters: Recent changes could have unintended consequences on performance. Expected answer: A major update was rolled out at the beginning of the quarter. Impact on approach: We'd focus on analyzing the impact of the recent update on fraud detection rates.
