When Does a Business Interruption Claim Arise?

Any unexpected event that forces a full or partial cessation of normal business operations can trigger a business interruption loss. Common scenarios include:

Fire & Smoke Damage

Structural damage or smoke contamination that shuts down or significantly impairs operations at a business premises.

Flood & Water Damage

Flooding events, whether natural or infrastructure-related — that cause property damage and force closure.

Cyber Attack

Ransomware, data breaches, or system outages that bring business operations to a halt and result in measurable revenue loss.

Power & Utility Outages

Extended outages affecting production capacity, refrigeration, or access to facilities.

Property Damage

Third-party damage to a business’s property, including construction impacts, vehicle incidents, or vandalism.

Government-Ordered Closures

Mandated shutdowns or operational restrictions, including pandemic-related orders, that restrict normal business activity.

Supply Chain Disruption

Contingent business interruption caused by an insured event at a key supplier or customer.

Litigation & Disputes

Losses stemming from wrongful acts, contract breaches, or injunctions that disrupt ongoing business operations.

How We Quantify Your Loss?

Our process is systematic, transparent, and designed to withstand scrutiny at every stage — from initial claim to arbitration or trial.

1. Document Review

Review of financial records including daily, weekly, and monthly revenues, income statements, tax returns, and management accounts for the period before, during, and after the interruption.

2. Period of Impact

Determine the commencement, duration, and end of the indemnity period — the window during which the interruption caused measurable financial losses.

3. Industry & Market Research

Conduct industry research to isolate and adjust for external economic factors — ensuring the loss calculation reflects the event’s true impact, not broader market conditions.

4. Projected Performance

Reconstruct the but-for financial performance of the business — what revenue and profit would have been achieved absent the interrupting event — using trending, benchmarking, and comparables.

5. Loss Calculation

Quantify the net business interruption loss: comparing projected versus actual performance, accounting for saved expenses, mitigation efforts, and policy-specific coverage terms.

6. Reporting & Expert Testimony

Deliver a clear, defensible written report — and if required, provide expert witness testimony in mediation, arbitration, or trial proceedings.
