Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has this 20% decrease been consistent across all quarters, or is it more pronounced in certain periods?

Why it matters: Seasonal patterns could indicate cyclical business trends rather than a persistent problem. Expected answer: The decrease is relatively consistent across quarters. Impact on approach: If seasonal, we'd focus on year-over-year comparisons and industry benchmarks.

• Considering the specificity of "small business" cards, I'm curious about the definition. Has there been any change in how Mastercard categorizes small businesses in the past year?

Why it matters: A shift in categorization could artificially alter the average transaction value. Expected answer: No changes in small business categorization. Impact on approach: If changed, we'd need to recalculate metrics using consistent criteria.

• Given the focus on transaction value, I'm wondering about transaction volume. Has there been a corresponding change in the number of transactions processed?

Why it matters: This helps distinguish between fewer high-value transactions and more low-value transactions. Expected answer: Transaction volume has remained relatively stable. Impact on approach: If volume increased, we'd explore shifts in purchasing behavior; if decreased, we'd investigate customer retention issues.

• Thinking about external factors, have there been any significant changes in Mastercard's small business credit card offerings or rewards programs in the past year?

Why it matters: Changes in card features could influence spending behavior. Expected answer: No major changes to card offerings or rewards. Impact on approach: If changes occurred, we'd analyze their impact on transaction values.
