FAQs
- Is bulk reserving less accurate than case reserving?
- Bulk reserves are inherently estimates based on averages and may not reflect the specifics of individual claims. However, when applied to large homogeneous groups, the statistical averaging effect produces aggregate estimates that are often quite accurate.
- When is bulk reserving most appropriate?
- Bulk reserving is most appropriate for high-frequency, low-severity, short-tail lines where individual claim investigation is not cost-effective or practical given volume. It is also standard practice for IBNR estimation across all lines.
- How do regulators view bulk reserves?
- Regulators accept bulk reserving as a legitimate methodology provided it is applied consistently and supported by credible actuarial analysis. Appointed actuaries must opine on the reasonableness of all loss reserve components, including bulk estimates.
