• Competition and alternative capital — Filing risk factors cite challenges from competitors, industry consolidation, alternative capital and technological advancements including increased use of analytics and artificial intelligence.
• Cyclical pricing — The 10-K states that the cyclical nature of insurance and reinsurance may result in declines in pricing and more competitive terms and conditions.
• Third-party systems, cyber and AI — Risks include cybersecurity threats, misuse of artificial intelligence and reliance on third-party information technology systems that may fail, be disrupted or require replacement.
