How Contingent Business Interruption Pays Out When Your Key Food Supplier Shuts Down

What Actually Has to Happen for CBI to Trigger?

CBI coverage does not respond just because a supplier is late, out of stock, or difficult to reach. The trigger requires two things to line up at the same time: the supplier must suffer direct physical loss or damage from a covered cause of loss (fire, windstorm, flood where covered, equipment breakdown, or similar), and that damage must be severe enough to actually prevent them from fulfilling your orders. A supplier who simply raises prices, prioritizes a bigger customer, or decides to exit your market has not experienced a covered physical loss — so there is nothing for CBI to attach to.

This is the single most misunderstood part of contingent coverage. Restaurant owners often assume any supply disruption counts. In practice, the underlying cause has to trace back to physical damage at the supplier's location, not a commercial or financial decision.

Does the Supplier Have to Be Named in Your Policy?

In most standard CBI forms, yes. Insurers typically require the supplier to be specifically identified — "scheduled" — on the policy before a loss occurs. This is why reviewing your named suppliers annually matters: if your restaurant switched primary distributors last year and never updated the schedule, a loss at your current supplier's facility may not be covered at all, even though a loss at your old (still-scheduled) supplier would be.

Some markets offer blanket contingent coverage, which extends protection to unnamed or unscheduled suppliers automatically, usually subject to a lower sublimit than scheduled coverage. Blanket coverage is valuable for restaurants with rotating or seasonal vendors, but it is not the default — you have to ask for it and confirm it is actually on the policy, not assumed.

How Is the Payout Actually Calculated?

The calculation mirrors ordinary business interruption math, but the loss has to be traced back to the supplier disruption rather than damage at your own restaurant. Insurers generally look at:

• Lost net income — the income your restaurant would have earned had the supplier kept delivering, based on historical financial records
• Continuing normal operating expenses — rent, payroll, and fixed costs that keep running even though revenue drops
• The period of restoration — how long it reasonably takes the supplier to resume normal deliveries, not how long it takes your restaurant to find an alternative

Because the payout is tied to the supplier's own recovery timeline, documentation from or about the supplier's repair and restart process matters as much as your own restaurant's books. IRMI's coverage commentary on whether your supply chain is covered by contingent business interruption walks through this same payout logic in more depth.

What Waiting Period Applies Before Coverage Kicks In?

Most CBI coverage includes a waiting period — commonly 24 to 72 hours, though this varies by policy — before the income-loss clock starts. Short disruptions that resolve within that window typically produce no claim at all, even if they caused real, felt disruption in the kitchen. This is one reason CBI is best understood as protection against extended supplier outages (weeks to months), not brief hiccups.

Why Unscheduled Suppliers Are Often Left Uncovered

Because standard CBI ties coverage to named suppliers, a restaurant that sources produce or proteins from whichever vendor has the best price that week — rather than a fixed primary distributor — can end up with a coverage gap it never knew existed. If a loss hits an unscheduled supplier and the policy has no blanket extension, the claim can be denied outright, regardless of how real the income loss was.

Restaurants with a genuinely single-source relationship — one primary distributor for a signature ingredient — carry the sharpest version of this exposure. That exact scenario, where a restaurant cannot simply substitute without changing what the restaurant is, is covered in more depth in our discussion of Dependent Property Coverage.

How Does CBI Differ From Extra Expense Coverage?

CBI replaces income you lost because a supplier could not deliver. It is not designed to reimburse what you spent trying to work around the problem — that is a separate coverage. For a full breakdown of how those reimbursement costs are handled, see the site's existing Extra Expense Coverage glossary page rather than treating the two as interchangeable.

What Should You Do Before You Ever Need to File a Claim?

Confirm which suppliers are actually named on your policy schedule, ask your broker directly whether blanket contingent coverage is included, and keep supplier contracts and order history current and accessible. When a disruption does happen, the documentation you will need to prove both the supplier relationship and the supplier's own damage is covered separately in our guide to filing a supply chain disruption claim.
