FAQs
- Why do some insurers operate with combined ratios above 100%?
- Insurers with long-tail liabilities collect premiums years before paying claims, generating substantial investment float. In periods of high interest rates, investment income on this float can more than offset modest underwriting losses. However, this model creates fragility in low-rate environments.
- How does the combined ratio relate to underwriting profit?
- The combined ratio is the inverse of the underwriting profit margin: a 97% combined ratio implies a 3% underwriting profit margin on premium. Subtracting 100 from the combined ratio gives the underwriting profit (negative) or loss (positive over 100) as a percentage of premium.
- What is a realistic target combined ratio for a well-run commercial lines carrier?
- Targets vary by line and business model, but most carriers target a combined ratio in the 93% to 97% range, recognizing that some years will produce worse results due to catastrophe activity. Specialty lines with lower competition may achieve better ratios; commodity lines face more pressure.
