Contingent Business Interruption
A business does not need to suffer direct physical damage to experience a significant financial loss. When a key supplier cannot deliver, when a principal customer cannot receive goods, when a utility provider fails to supply power — the financial consequences for the insured can be as severe as if the damage had occurred on their own premises.
Contingent Business Interruption (CBI) covers precisely this exposure. But quantifying a CBI loss is more complex than a standard BI assessment. The financial trail does not begin at the insured’s own accounts. It begins at a third party’s premises, passes through a dependency relationship and arrives — transformed — in the insured’s profit and loss account.
BINOCLE provides independent CBI loss quantification for Insurers and Reinsurers. We follow the financial logic of the dependency, establish the causal chain between the third-party event and the insured’s loss, and deliver a rigorous, evidence-based assessment of the true financial impact.
What We Quantify
Supplier dependency losses
When damage at a key supplier’s facility prevents the insured from obtaining the materials, components or services required to maintain production, we quantify the resulting loss of gross profit or revenue. This requires understanding both the supplier’s output disruption and the insured’s ability to source alternatives — at what cost, over what timeframe and to what degree of effectiveness.
Customer dependency losses
When damage at a principal customer’s premises prevents them from receiving the insured’s goods or services, we quantify the revenue foregone and the fixed costs that continued during the period of interruption. We assess whether alternative customers were available, whether output could be redirected, and what the net financial impact of the dependency failure was.
Utility and infrastructure dependency losses
Losses arising from the failure of power, water, gas or telecommunications supply — whether from damage to a utility provider’s infrastructure or from an event at a shared facility — require analysis of the insured’s operational dependency on that service and the financial consequences of its interruption. We quantify the loss period, the operational impact and the reasonable costs of mitigation.
Leader and contributing property losses
In certain policy structures, coverage extends to losses arising from damage at a specific named location — a market, an exhibition centre, an anchor tenant — upon which the insured’s business depends for footfall or custom. We assess the insured’s financial dependency on that location and the economic loss attributable to its unavailability.
Mitigation and alternative sourcing costs
A well-managed CBI claim involves active mitigation — the insured sourcing alternative suppliers, redirecting logistics or adapting production processes. We assess the cost and effectiveness of those mitigation steps, determine whether they fall within the policy’s increased cost of working provisions and factor their outcome into the net loss calculation.
WHY BINOCLE
The Challenge of CBI Quantification
Access to third-party financial information.
The source of the loss is not the insured’s own operation — it is a third party’s. Obtaining the financial and operational data needed to establish the extent of the supplier’s or customer’s disruption, and translating that disruption into the insured’s financial terms, requires careful management of information flows across organisational boundaries.
Establishing the dependency relationship.
The causal chain must be clearly documented: the insured event at the third-party location, the specific impact on that party’s ability to supply or receive and the direct financial consequence for the insured. Gaps in that chain are the most common basis for coverage disputes in CBI claims.
Separating CBI loss from concurrent causes.
Insured businesses rarely have a single dependency. When a CBI event occurs, other factors — market conditions, pre-existing operational issues, unrelated customer behaviour — may have contributed to the financial outcome. We isolate the CBI-attributable loss from non-covered causes with methodical precision.
Policy scope and named versus unnamed contingencies.
CBI policies vary considerably in their scope. Some cover only named suppliers or customers; others extend to unnamed contingencies within a defined category. The financial assessment must be conducted within the boundaries of the applicable coverage, which requires a thorough reading of the policy wording before analysis begins.
OUR EXPERIENCE
CBI claims have grown in frequency and complexity as global supply chains have become more concentrated and interdependent.
BINOCLE has quantified CBI losses across a range of industries and dependency structures, including:
- Manufacturing sector supply chain failures following natural catastrophe events
- Energy sector losses arising from grid failure or pipeline disruption
- Retail and distribution losses arising from damage at logistics hubs or distribution centres
- Hospitality and events losses arising from damage at dependent venues or infrastructure
- Technology sector losses arising from data centre or cloud infrastructure failures
Our experience across both direct BI and CBI claims means we understand the relationship between the two — and the importance of correctly allocating loss between covered and non-covered causes when both types of loss arise from the same event.
HOW WE DO IT
Our Approach
Mapping the dependency before quantifying the loss
Before any financial analysis begins, we establish a clear picture of the insured’s dependency on the affected third party — the contractual relationship, the operational mechanics, the proportion of the insured’s activity that relied on that party and the alternatives available. This mapping exercise determines the boundaries of the loss and prevents scope creep in either direction.
Working across organisational boundaries
Policy-led analysis
The coverage parameters — named versus unnamed, the definition of the contingency, the indemnity mechanism — directly shape the methodology. A CBI assessment conducted outside the policy’s scope, however technically accurate, is not useful to the instructing party.
Integrated reporting with the wider claims team
CBI claims typically involve multiple parties: the insured, the third-party whose damage triggered the claim, loss adjusters, legal advisers and potentially the third party’s own insurers. We structure our reporting to integrate with the broader claims team, providing the financial analysis in a format that supports the overall settlement strategy.

Frequently Asked Questions
What is contingent business interruption (CBI) insurance?
Contingent business interruption insurance covers the financial losses suffered by a business when its operations are disrupted not by damage to its own property, but by damage to the property of a third party on which the business depends — typically a key supplier, a principal customer or a utility provider. CBI coverage is distinct from standard business interruption insurance and subject to its own specific terms and conditions.
What is the difference between business interruption and contingent business interruption?
Standard business interruption insurance responds to financial losses caused by physical damage to the insured’s own property. Contingent business interruption responds to financial losses caused by physical damage at a third party’s location — a supplier, a customer or a utility provider — that disrupts the insured’s operations as a result. The financial impact on the insured may be similar, but the causal chain and the documentation required to establish the loss are fundamentally different.
How is a contingent business interruption loss quantified?
A CBI loss is quantified by establishing the financial impact on the insured of the third party’s inability to supply or receive goods and services during the period of their disruption. This requires analysis of the insured’s financial dependency on that third party, the extent and duration of the disruption, the mitigation steps taken and their effectiveness and the net loss of gross profit or revenue attributable to the dependency failure — all within the specific coverage parameters of the CBI policy.
What documentation is needed for a CBI claim?
Core documentation includes the insured’s financial records for the loss and prior periods, evidence of the contractual or commercial relationship with the affected third party, information on the third party’s disruption and recovery timeline and records of any alternative sourcing or mitigation arrangements. Obtaining information from the third party is often the primary logistical challenge in a CBI claim.
Do named supplier and unnamed supplier CBI policies require different approaches?
How long does a CBI assessment typically take?
CBI assessments are generally more complex and time-consuming than standard BI claims, primarily because they involve obtaining information from a third party. The timeline depends on the complexity of the loss, the cooperation of the affected third party and the availability of documentation. BINOCLE provides a realistic assessment of timeline on instruction and maintains continuous communication with the instructing party throughout the process.
