9.4 Insurance-linked securities

Insurance-linked securities (ILS) are innovative financial tools that transfer insurance risk to capital markets. They expand capacity beyond traditional reinsurance, allowing insurers to manage catastrophe exposure while offering investors uncorrelated returns.

ILS come in various forms, including catastrophe bonds, industry loss warranties, sidecars, and longevity bonds. These instruments use special purpose vehicles, trigger mechanisms, and collateral arrangements to structure risk transfer between sponsors and investors.

• Insurance-linked securities (ILS) transfer insurance risk to capital markets, expanding capacity beyond traditional reinsurance

1 of 3

• Debt instruments that transfer specific catastrophe risks from insurers to investors
• Investors receive interest payments but risk losing principal if a predefined catastrophe event occurs
• Commonly cover perils such as hurricanes, earthquakes, and floods
• Typically have a 3-5 year term and offer higher yields than traditional bonds

Industry loss warranties

• Derivative contracts that pay out based on industry-wide losses from catastrophic events
• Provide coverage when total insured losses exceed a specified threshold
• Often used by reinsurers to hedge their own exposure to large-scale disasters
• Settlement based on third-party loss estimates (PCS, PERILS)

Sidecars

• Special purpose vehicles that allow investors to participate in a portion of an insurer's premiums and losses
• Provide temporary reinsurance capacity, often for specific lines of business or regions
• Investors share in underwriting profits but also bear potential losses
• Typically have shorter durations than catastrophe bonds (1-3 years)

Longevity bonds

• Securities that transfer longevity risk from pension funds and life insurers to investors
• Payouts linked to survival rates of a specified population cohort
• Help manage the financial impact of increasing life expectancy on long-term liabilities
• Can be structured as swaps or bonds with variable coupons based on mortality experience

Structure and mechanics

Special purpose vehicles

• Legal entities created to issue ILS and isolate the risk from the sponsor's balance sheet
• Often domiciled in tax-efficient jurisdictions (Bermuda, Cayman Islands)
• Hold collateral and manage cash flows between sponsors and investors
• Ensure bankruptcy remoteness to protect investor interests

Trigger mechanisms

• Define conditions under which ILS payouts occur
• Indemnity triggers: based on actual losses incurred by the sponsor
• Parametric triggers: linked to objective, measurable events (wind speed, earthquake magnitude)
• Industry loss triggers: activated when industry-wide losses exceed a predetermined threshold
• Modeled loss triggers: use catastrophe models to estimate losses from an event

Collateral arrangements

• Funds held in trust to secure investor principal and potential payouts
• Typically invested in high-quality, short-term securities (Treasury bills, money market funds)
• Ensure immediate availability of funds in case of a triggering event
• May include provisions for partial release of collateral over the life of the security

Market participants

Sponsors

• Insurance and reinsurance companies seeking to transfer risk
• Government entities managing catastrophe exposure (Florida Hurricane Catastrophe Fund)
• Corporations with significant catastrophe risk (energy companies, large property owners)
• Develop ILS structures in collaboration with investment banks and modeling firms

Investors

• Institutional investors seeking portfolio diversification (pension funds, hedge funds)
• Specialized ILS funds focusing exclusively on insurance-linked investments
• Evaluate ILS opportunities based on risk-return profiles and correlation with other asset classes
• May require specialized knowledge to assess complex risk models and structures

Rating agencies

• Provide credit ratings for ILS to help investors assess risk
• Evaluate factors such as trigger mechanisms, collateral quality, and sponsor creditworthiness
• Major agencies involved include S&P, Moody's, and Fitch
• Ratings influence pricing and marketability of ILS instruments

Modeling firms

• Develop catastrophe models used to assess and price ILS risk
• Provide analytical tools for sponsors, investors, and rating agencies
• Key players include AIR Worldwide, RMS, and CoreLogic
• Continuously refine models based on new scientific data and historical loss experience

Benefits and drawbacks

Risk transfer advantages

• Expand reinsurance capacity beyond traditional markets
• Provide multi-year coverage, reducing renewal risk for sponsors
• Offer customizable structures to match specific risk profiles
• Allow access to capital markets during hard reinsurance market conditions

Diversification for investors

• Low correlation with traditional asset classes (stocks, bonds)
• Potential for higher yields compared to similarly rated corporate bonds
• Opportunity to participate in insurance market returns without underwriting expertise
• Geographic and peril diversification within ILS portfolios

Pricing and liquidity challenges

• Complex modeling and structuring can lead to high issuance costs
• Limited secondary market liquidity compared to traditional securities
• Pricing may be volatile following major catastrophe events
• Investors may face challenges in accurately assessing underlying risks

Regulatory environment

Securities regulations

• ILS subject to securities laws in jurisdictions where they are issued and traded
• SEC oversight in the US, including registration and disclosure requirements
• Regulation S offerings allow for simplified issuance to non-US investors

• Withholding tax implications for cross-border transactions
• Potential for tax-exempt status of certain collateral arrangements
• Investors must consider tax treatment of ILS returns in their jurisdictions

Pricing and valuation

Risk modeling

• Utilize sophisticated catastrophe models to estimate potential losses
• Incorporate historical data, scientific research, and expert judgment
