Contingent business interruption

Protect your business from financial losses caused by disruptions to key suppliers.

Contingent business interruption (CBI) insurance helps safeguard your business against lost income and extra costs that arise when disruptions to suppliers or customers interrupt your operations.

Unlike traditional business interruption insurance, which covers losses from damage to your own property, CBI typically responds when operations are interrupted because a key supplier or customer suffers direct physical loss or damage.

Common triggers for CBI insurance

CBI insurance is typically triggered by physical damage or disruptions affecting direct Tier 1 suppliers on a property policy. However, in some cases, it may be possible to negotiate a smaller sublimit for Tier 2 suppliers. These covered perils can be grouped into the following categories:

  • Natural catastrophes, including floods, storms, and earthquakes, which tend to be the most common drivers of CBI claims
  • Fire and accidental damage, including fires, explosions, and other accidents occurring at supplier facilities
  • Other covered perils, potentially including machinery breakdown, vandalism, theft, and other insured physical damages that can disrupt supply chains

Is my organization a good candidate for CBI insurance?

  • Do you rely on sole or single-source suppliers?
  • Do you rely on manual processes to collect and verify data for your Tier 1 suppliers?
  • Are your inputs hard to replace? Do they have long lead times?
  • Is your supplier base concentrated in high-risk regions?
  • Have you had difficulties in the past securing sufficient CBI coverage?

If yes, securing or strengthening your CBI coverage is likely relevant to your business.

Common CBI coverage gaps

CBI coverage is highly dependent on specific policy terms, including how dependent properties and covered perils are defined. Understanding common coverage gaps is essential to avoid unexpected exposures and ensure your risk transfer strategy is effective.

Many insurance policies often exclude certain triggers, especially non-physical events, which can leave significant coverage gaps. Key examples include:

  • Exclusions for cyber incidents, labor strikes, pandemics, insolvency
  • CBI or contingent time element (CTE) losses resulting from catastrophic perils such as earthquakes (EQ), explosions or emissions (EM), floods, and other CAT perils, unless these are specifically endorsed

Coverage generally applies to direct suppliers, which can restrict protection if critical suppliers or facilities are omitted. Consider:

  • Policies covering only specifically named or scheduled suppliers, leaving unscheduled but essential suppliers uncovered
  • Narrow definitions of dependent properties that may exclude certain facilities
  • Differences between facility-level and corporate-level coverage scopes

Structural limits and claims requirements can impact recoveries and cash flow. Important factors include:

  • Sublimits on CBI coverage or specific perils that cap potential recoveries
  • Waiting periods and deductibles that delay or reduce claim payments
  • Challenges in proving causation and accurately quantifying losses, requiring strong evidence to support claims

 

The definition of waiting period is critical

The definition of the waiting period is critical because it establishes the precise start time for coverage, providing clarity about when benefits begin after a loss. Different interpretations, such as counting only work hours versus full calendar hours, can significantly extend the actual waiting duration, affecting the timing and availability of coverage

FAQs

Contingent business interruption (CBI) insurance protects a business against financial losses resulting from disruptions to key named suppliers. It typically covers lost earnings and extra expenses incurred when these external interruptions cause downtime or operational delays. For example, if a key supplier’s factory shuts down due to a natural disaster, CBI insurance can help cover the resulting loss of income and additional costs while your business is impacted.

Business interruption insurance covers financial losses resulting from damage to your own property that disrupts your operations — such as a fire at your facility causing downtime and lost revenue. CBI insurance, on the other hand, protects against losses caused by disruptions at third-party location critical to your business, like a supplier’s factory. For example, if your warehouse is damaged by a storm, business interruption insurance covers your losses. But if a supplier’s plant shuts down due to a flood, causing delays in your production, CBI insurance helps cover the resulting financial impact.

A dependent property is any third-party location or facility that your business relies on to operate. This includes supplier manufacturing locations, offsite warehouse locations, etc. Dependency is determined by the policy based on whether damage or disruption at these properties directly impacts your business operations or revenue. Essentially, if your business would suffer a loss due to an interruption at these locations, they are considered dependent properties under CBI insurance.

Losses under CBI insurance are typically measured using one or more of the following approaches:

  • Lost net profit: The difference between expected profits and actual profits during the interruption period, accounting for saved expenses.
  • Gross earnings: Total revenue lost due to the interruption, often used when net profit is difficult to calculate.
  • Extra expenses: Additional costs incurred to minimize the impact of the disruption, such as expedited shipping or temporary facilities. To support a claim, insurers usually require detailed documentation, including financial records, sales history, and evidence of mitigation efforts taken to reduce losses. The interruption period is established based on the time it takes to restore operations to their normal level, often defined by the policy terms and supported by operational and financial data.

The waiting period, also known as the deductible period, is the amount of time after a covered disruption before CBI insurance benefits begin to pay out. It represents the initial delay during which losses are not covered. Typical waiting periods range from 24 to 72 hours but can vary depending on the policy terms and insurer. A longer waiting period usually results in lower premiums but means your business must absorb losses during that initial timeframe. Understanding and planning for the waiting period is crucial, as it affects when claim payouts start and helps you prepare financially for any uncovered downtime.
