Which endorsement protects clients from losses due to perils in their supply chain?

The endorsement that protects clients from losses due to perils in their supply chain is the Contingent Business Interruption endorsement. This type of coverage comes into play when a business experiences a disruption not from direct damage to its own property, but rather from damage to the property of suppliers or customers. For instance, if a supplier's facility is damaged by a covered peril, causing a supply chain disruption, this endorsement helps cover the financial losses the insured company incurs due to the inability to obtain necessary goods or services.

This is especially relevant for businesses that rely heavily on external suppliers and need to continue their operations without significant financial losses in the event of an interruption elsewhere in the supply chain. Other endorsements listed, while relevant to specific types of coverage, do not specifically address the risks associated with supply chain disruptions.
