Income-loss coverage tied to damage at a supplier, customer, or other outside property.
Contingent business interruption is income-loss coverage that may respond when the insured business suffers interruption because a key supplier, customer, manufacturer, or other dependent property experiences a covered loss.
The insured premises may be physically untouched. The interruption arises because the business depends on another location or operation that was damaged.
Modern businesses often rely on a small number of suppliers, processors, distributors, landlords, or anchor customers. A serious loss at one of those outside locations can disrupt sales and operations just as effectively as a fire at the insured’s own premises.
That is why this term matters. It expands the reader’s understanding of business interruption from “my building was damaged” to “my business was disrupted because a critical external dependency was damaged.”
Contingent business interruption is usually an extension or specialized form of business interruption or business income coverage. The wording often focuses on:
These claims can be more complex than ordinary business-income claims because the insured has to prove both the dependency relationship and the financial effect of damage at another location.
| Coverage path | What triggers it |
|---|---|
| Business Interruption | Covered damage interrupts the insured’s own premises or operations |
| Contingent business interruption | Covered damage interrupts a supplier, customer, processor, or other outside dependency |
| Dependent-Property Coverage | The wording framework identifying what outside properties qualify |
| Civil Authority Coverage | Public authority action blocks or restricts access after a covered nearby event |
A manufacturer depends on one specialized parts supplier. A fire at the supplier’s plant stops production for several weeks, and the manufacturer cannot complete customer orders. If the policy includes contingent business interruption wording and the trigger fits the contract, the resulting income loss may be considered under that coverage.
The biggest mistake is assuming every supply-chain problem is insured. It is not. Delay, market conditions, labour issues, and general commercial disruption do not automatically fall within contingent business interruption wording.
Another mistake is treating this as the same thing as ordinary business interruption. The insured location itself may not be the damaged site, which makes the trigger and proof requirements more specific.
Readers also underestimate the importance of the wording that defines dependent properties. A broad commercial dependency in everyday business terms may still fall outside the policy language.
Another mistake is treating contingent BI as a general answer to any supply-chain disruption. The coverage still turns on damage-based trigger wording rather than on general economic interruption.
Dependent-property wording, covered triggers, waiting periods, and proof requirements vary materially. These claims are often contract-sensitive and evidence-heavy.
