31 CFR 50.22: No material difference from other coverage.

(a) Terms, amounts, and other coverage limitations. As provided in § 50.20(a)(2), an insurer must offer coverage for insured losses arising from an act of terrorism that does not differ materially from the terms, amounts, and other coverage limitations (including deductibles) applicable to losses arising from events other than acts of terrorism. For purposes of this requirement, “terms” excludes price.

(b) Limitations on types of risk. An insurer is not required to cover risks that it typically excludes or does not write to satisfy the requirement to make available coverage for losses resulting from an act of terrorism that does not differ materially from the terms, amounts, and other coverage limitations applicable to losses arising from events other than acts of terrorism. For example, if an insurer does not cover all types of risks, either because the insurer is outside of direct state regulatory oversight, or because a state permits certain exclusions for certain types of losses, such as nuclear, biological, or chemical events, then the insurer is not required to make such coverage available.
