How Terrorism Is Factored Into Premiums
Workers' compensation premiums include a terrorism surcharge that reflects the potential cost of catastrophic events. Insurers calculate this surcharge by estimating the probability of a terrorism incident that would trigger a claim, multiplying that probability by the expected claim amount, and then adding a margin for administrative costs.

Key Elements of the Calculation
Actuarial tables used for terrorism exposure are built from historical terrorism data, intelligence reports, and industry‑specific risk profiles. The calculation follows these steps:
- Exposure Assessment: Determine the business's physical presence in high‑risk areas, the nature of its operations, and security measures.
- Probability Estimation: Apply statistical models to estimate the annual likelihood of a terrorism event affecting the business.
- Severity Projection: Estimate the average claim size based on past terrorism claims and potential coverage limits.
- Premium Allocation: Compute the surcharge by multiplying probability by severity, then add a fixed administrative fee.
Industry Variations
Different sectors face varying terrorism risks. For example, the hospitality industry often has higher exposure due to large public venues, whereas manufacturing may have lower exposure but higher potential claim severity if a facility is targeted. Insurers adjust the surcharge accordingly.
Managing Terrorism Premiums
Employers can reduce their terrorism surcharge by implementing robust security protocols, conducting regular risk assessments, and obtaining comprehensive security coverage. Many insurers offer discounts for documented security improvements, such as surveillance systems, controlled access, and employee training.
Regulatory Context
In some states, terrorism coverage is mandated for certain businesses, and the surcharge is capped by law. Employers should verify state requirements to ensure compliance and to avoid unexpected premium increases.
