Reducing Uncertainty in Business Interruption Claims

  • Date28 July, 2026

Business interruption claims have become increasingly complex due to supply chain disruption, inflation, contingent business interruption exposures and changing market conditions. As financial losses often exceed the cost of repairing physical damage, these claims can attract significant scrutiny from both insurers and policyholders. This can increase the likelihood of disputes, delay resolution and prolong financial uncertainty following a loss.

When a major property loss occurs, stakeholders are often looking for answers to critical questions:

  • What is the likely financial exposure?
  • What should reserves be set at?
  • How quickly can reliable figures be produced?
  • When can advance payments be made?

The ability to answer these questions early can significantly influence the efficiency of the claims process and the speed of recovery.

While every claim is different, many disputes stem from the same underlying issues: policy interpretation, revenue projections, expense treatment and incomplete documentation. Fortunately, most of these challenges can be addressed through early communication, transparency and a clear approach to loss measurement.

Why Commercial Property Losses Are Becoming More Complex

Business interruption losses are often more difficult to quantify than the physical property damage itself. Calculating a loss requires parties to determine what would have happened had the incident not occurred, while also accounting for external factors that may have influenced performance.

Supply chain disruption, inflation, labour shortages and economic uncertainty can all affect revenue and expenses during a period of interruption, making it harder to establish an accurate basis for measurement.

Four Common Causes of Claim Disputes

Based on our experience analysing business interruption claims across a range of industries, these disputes most commonly arise in four key areas.

1. Policy Language

Many disputes begin with policy wording.

Terms such as period of restoration, ordinary payroll, extra expense and deductible provisions may be interpreted differently by insurers and policyholders. Within business interruption insurance claims, even small differences in interpretation by stakeholders can have a significant impact on the final claim calculation.

While MDD does not interpret coverage under the policy and instead relies on the direction of the insurer, a thorough review of policy provisions at the outset of the claim can help ensure that all parties are working from the same understanding.

2. Revenue Projection Disagreements

Projecting what revenue would have been earned if the loss had not occurred is often one of the most scrutinised parts of a business interruption claim.

There is rarely a single correct methodology. Depending on the circumstances, calculations may be based on historical trends, averages, benchmarking or other approaches. Market conditions, inflation, political events and business growth plans can further complicate the analysis.

Clear documentation of assumptions and agreement on methodology can help reduce disagreements and support a more consistent outcome.

3. Expense Analysis

Another frequent source of dispute is the treatment of expenses during the interruption period.

Business interruption calculations typically require an assessment of which costs continued, which were reduced and which were completely avoided as a result of the loss. Differences in opinion regarding fixed and variable expenses can significantly affect the value of a claim.

Reviewing financial information before, during and after the loss can provide valuable insight into how expenses reacted during the interruption period.

4. Incomplete Documentation

Even straightforward claims can become difficult when supporting information is incomplete, inconsistent or slow to arrive.

Missing records limited historical data and delays in responding to requests can extend the claims process and increase opportunities for misunderstanding.

Establishing documentation requirements early and maintaining organised information-sharing processes can help improve efficiency and reduce uncertainty.

The Cost of Prolonged Disputes

Disputes can have consequences beyond the claim calculation itself.

Potential impacts include:

  • Delayed claim payments
  • Increased legal and consulting costs
  • Additional pressure on business operations
  • Strained relationships between insurers and policyholders
  • Greater uncertainty during recovery

For businesses already dealing with a significant loss event, prolonged disputes can become a major distraction from restoring normal operations.

How to Reduce Disagreements Before They Escalate

While disputes cannot always be avoided, several best practices can significantly reduce the likelihood of disagreement.

Establish Alignment Early

Claims tend to progress more efficiently when stakeholders agree on policy application, methodology and information requirements at the outset.

For major property losses, pre-agreed approaches to loss measurement—such as MDD’s Major Risk solution, where MDD is identified as the Nominated Preferred Accountant—can help support reserving decisions, improve consistency across claims and locations, and reduce delays when a loss occurs.

Promote Transparency

Explaining why certain financial records are required and how they will be used helps build confidence in the process and reduces unnecessary friction.

Encourage Collaboration

Regular communication between insurers, policyholders, adjusters and financial experts allows questions to be addressed before they become larger issues.

The Role of Forensic Accountants

Forensic accountants play an important role in helping stakeholders understand and quantify the financial impact of a loss.

Their work often involves assessing business operations, analysing financial records, measuring losses in accordance with policy terms and communicating findings clearly to all parties involved. Early involvement can also provide greater clarity around financial exposure and help stakeholders make informed decisions throughout the lifecycle of a claim.

By combining financial expertise with an understanding of insurance policies and claim methodologies, forensic accountants can help stakeholders evaluate assumptions, support revenue projections and provide greater transparency throughout the claims process.

Conclusion

Most business interruption claim disputes are not inevitable. They often arise from confusion regarding the policy language, differing assumptions, incomplete documentation or a lack of communication.

By establishing expectations early, maintaining transparency throughout the process and working collaboratively, insurers and policyholders can improve outcomes and accelerate claim resolution. Experienced forensic accountants can further support this process by providing objective analysis and helping ensure that losses are measured consistently and in accordance with policy terms.

Ultimately, reducing uncertainty in business interruption claims starts with achieving clarity early enabling stakeholders to make informed decisions, establish accurate reserves and focus on recovery following a property loss.
