Clarifying Questions (3 minutes)

• Considering the timing, I'm wondering if there have been any recent changes to the payment system. Have there been any updates or new features implemented in the last 30-60 days?

Why it matters: Recent changes could directly impact chargeback rates. Expected answer: Yes, a new fraud detection algorithm was implemented. Impact on approach: If confirmed, we'd focus on the algorithm's performance and potential false positives.

• Given the significant increase, I'm curious about the distribution across merchant categories. Has the 30% increase been uniform across all merchant types, or are certain categories more affected?

Why it matters: Helps identify if the issue is systemic or category-specific. Expected answer: E-commerce and digital goods merchants are disproportionately affected. Impact on approach: We'd investigate category-specific factors and tailor solutions accordingly.

• Thinking about user behavior, I'm wondering if there's been a change in the typical transaction profile. Has there been any shift in average transaction values or frequency?

Why it matters: Changes in transaction patterns could indicate fraud or economic factors. Expected answer: There's been a slight increase in high-value transactions. Impact on approach: We'd examine the correlation between transaction value and chargeback rates.

• Considering external factors, I'm curious about any recent regulatory changes. Have there been any updates to payment processing regulations in key markets?

Why it matters: Regulatory changes could impact chargeback processes and consumer behavior. Expected answer: No significant regulatory changes in the past quarter. Impact on approach: We'd focus more on internal factors and market conditions.
