In group underwriting, which factor is targeted to provide more accurate projections of future loss experience?

• A. Turnover of the group
• B. Size of the group
• C. Financial strength of the group
• D. Provisions

Answer: (B)

The main idea is that predicting future loss experience relies on having a large, representative set of data. In group underwriting, the size of the group—the number of exposure units—has the biggest impact on how accurately past losses forecast future claims. When more members are in the group, random fluctuations tend to cancel out, and the observed loss experience aligns more closely with the true underlying loss rate. This is the law of large numbers in action: a bigger pool yields more stable, reliable projections for pricing and reserves. While turnover, financial strength, and provisions matter for other reasons—such as risk mix changes or financial viability—they don’t improve projection precision as directly as increasing the group size.
