Reinsurance is a vital risk management tool in the insurance industry. It allows insurers to transfer portions of their risk to other companies, enhancing financial stability and increasing capacity to underwrite larger or more complex risks.

This topic explores the fundamentals, types, and market dynamics of reinsurance. It covers legal aspects, financial implications, program design, and alternative risk transfer methods, providing a comprehensive overview of this crucial insurance concept.

• Enables access to specialized expertise and global diversification of risk

Historical development

• Originated in the 14th century with marine insurance in Italy
• Evolved significantly after the Great Fire of London in 1666, highlighting the need for risk spreading
• Lloyds of London emerged as a major reinsurance market in the 18th century

Types of reinsurance agreements

• Reinsurance agreements come in various forms to address different risk transfer needs
• Selection of appropriate agreement type depends on insurer's risk profile and strategic objectives
• Understanding different agreement structures crucial for effective risk management in insurance

Treaty vs facultative

• Treaty reinsurance covers entire portfolios of risks automatically
  • Provides ongoing protection for a specified class of business
  • Efficient for handling large volumes of similar risks
• Facultative reinsurance involves case-by-case evaluation of individual risks
  • Offers flexibility for unique or high-value exposures
  • Allows reinsurers to carefully assess and price each risk
• Hybrid arrangements combine elements of both treaty and facultative reinsurance

Proportional vs non-proportional

• Proportional reinsurance involves sharing premiums and losses in fixed percentages
  • Reinsurer assumes a predetermined portion of each risk
  • Includes quota share and surplus reinsurance
• Non-proportional reinsurance provides coverage above a specified retention level
  • Reinsurer pays losses exceeding a predetermined threshold
  • Includes excess of loss and stop loss reinsurance
• Choice between proportional and non-proportional depends on risk appetite and capital requirements

Quota share reinsurance

• Proportional agreement where reinsurer assumes fixed percentage of each risk
• Cedent and reinsurer share premiums and losses in the same proportion
• Provides automatic capacity for the ceding company
• Helps stabilize underwriting results and improve solvency ratios
• Often used by new or growing insurance companies to increase capacity

Surplus reinsurance

• Proportional agreement with variable cession percentage based on policy limits
• Allows ceding company to retain a fixed amount of each risk
• Reinsurer covers the "surplus" above the retention up to a specified maximum
• Provides flexibility in managing capacity for different risk sizes
• Enables insurers to write larger policies while maintaining consistent net retention

Excess of loss reinsurance

• Non-proportional agreement covering losses above a specified retention level
• Protects against severity of losses rather than frequency
• Various types include per risk, per occurrence, and aggregate excess of loss
• Helps insurers manage catastrophic events and large individual claims
• Retention and limit structure can be tailored to insurer's risk profile

Stop loss reinsurance

• Non-proportional agreement protecting against adverse loss ratios
• Triggers when overall losses for a line of business exceed a predetermined threshold
• Provides protection against both frequency and severity of losses
• Often used as a last line of defense in reinsurance programs
• Helps stabilize underwriting results and protect insurer's capital
