1987 — AIR Worldwide and the Birth of Commercial Catastrophe Modeling

Category: Property • Reinsurance • Analytics • Technology • Catastrophe Risk

Summary

In 1987, Karen Clark founded Applied Insurance Research (AIR) — the company that would become AIR Worldwide. That same year, AIR released CATMAP, the first commercial catastrophe‑loss analysis system ever used by insurers and reinsurers.

This was the moment catastrophe modeling became a formal discipline rather than an academic curiosity. AIR’s founding marks the beginning of modern, probabilistic cat modeling — the foundation of today’s global property‑catastrophe market.

I. The Founding of AIR (1987)

Karen Clark, a trained economist and catastrophe‑risk pioneer, founded AIR in Boston in 1987. Her goal was radical for its time:

Use computer simulation to estimate catastrophic losses before they occur.

This was the first attempt to commercialize catastrophe modeling for the insurance industry.

II. CATMAP: The First Commercial Catastrophe Model

Later in 1987, AIR released CATMAP, the first catastrophe‑loss analysis system available to insurers and reinsurers.

CATMAP introduced:

• event catalogs
• hazard footprints
• vulnerability curves
• portfolio‑level loss estimation

For the first time, insurers could quantify potential losses from hurricanes and earthquakes using probabilistic simulation rather than intuition or historical averages.

This was the birth of:

• EP curves
• AAL (Average Annual Loss)
• tail‑risk metrics

All of which are now standard in underwriting and reinsurance.

III. The Turning Point: Hurricane Andrew (1992)

AIR’s early models were validated dramatically when Hurricane Andrew struck Florida in 1992.

AIR estimated insured losses could exceed $13 billion, a figure widely dismissed at the time — but later proven accurate.

Andrew caused:

• more than 10 insurer insolvencies
• a reinsurance‑capacity crisis
• a surge in demand for scientific modeling

This event transformed AIR from a niche analytics firm into a central pillar of the global cat‑risk ecosystem.

IV. AIR’s Evolution

AIR remained privately held until it was acquired by ISO in 2002, later becoming part of Verisk Analytics.

Over time, AIR expanded into:

• global hurricane, earthquake, flood, and severe‑storm models
• terrorism and pandemic modeling
• casualty‑catastrophe and cyber modeling
• enterprise risk management platforms (e.g., Touchstone)

In 2022, AIR rebranded under Verisk Extreme Event Solutions.

V. Legacy

AIR’s founding in 1987 marks the beginning of the modern catastrophe‑modeling era. It transformed:

• underwriting
• reinsurance pricing
• capital allocation
• regulatory solvency standards
• the rise of ILS and cat bonds

AIR didn’t just build models. It created the framework for how the global insurance industry understands extreme events.

Reinsurance, Capital Markets & Global Market Transformation

• 1990s — Bermuda Reinsurer Boom — the Class of ’93 reinsurers adopted AIR models from inception, making AIR the analytical backbone of the new Bermuda market
• 1990s — Rise of Cat Bonds & ILS — AIR’s EP curves and hazard footprints became essential components of early cat‑bond trigger structures
