What is contingent business income insurance, and what does it cover?

Contingent business income insurance, also called dependent properties coverage, pays the income you lose when a supplier, customer or anchor business you depend on suffers physical damage from a covered event, such as a fire, and your own operations slow or stop as a result. It is a separate endorsement on a commercial property policy, usually limited to locations you name. It does not respond to your own premises, a utility outage, a vendor’s software failure or a closure with no physical damage. It is not the same as contingent bodily injury, which is liability coverage.

What contingent business income is

Business income coverage replaces the profit you lose while your own space is being repaired after a covered loss. It stops at your own property line. If your income depends on a business next door, across town or overseas, and that business burns down, the standard form has nothing to say about it.

Contingent business income, which the standard forms call dependent properties coverage, extends that promise to other businesses’ buildings. The trigger is the same kind of event the base policy covers, such as a fire, happening at a location you rely on. You do not own that location and cannot control its repair, which is why insurers want it named in advance.

The shorthand CBI is used for this coverage and also for contingent bodily injury, which is liability coverage for an injury caused by a product or advice. They are unrelated. If you run an app or software company and are weighing injury risk, read the guide on bodily injury against contingent bodily injury instead.

The four kinds of dependent property

The ISO schedule sorts the businesses you depend on into four groups. Contributing locations supply you with materials or services. Recipient locations take your products or services, as a distributor or a large customer does. Manufacturing locations make products for you to deliver to your own customers under contract. Leader locations are the businesses whose traffic you share, such as the anchor store in a shopping center.

Which ones you need depends on where your income actually comes from. A restaurant that buys from one specialty supplier has a contributing location. A caterer whose largest account is one corporate client has a recipient location. A shop in a mall has a leader location it did not choose and does not control.

The dependent property has to be physically damaged

Direct physical loss by a covered cause is the trigger, and it is the part owners find hardest to accept. A supplier that closes for a strike, a recall, a bankruptcy or a permit problem has not suffered physical loss. A supplier whose warehouse burns has. Courts have read the phrase strictly: in the COVID-19 cases most decisions held that a closure order or the presence of a virus was not physical loss, and in the Southern Hospitality case a hotel lost because it could not point to any damaged property.

The cause must also be one your own policy covers. If your policy excludes flood, a supplier’s flood damage will not trigger the endorsement either. The 2011 Thailand floods showed the other side of this: contingent extensions there were often written for fire, lightning and explosion only, so businesses insured for flood at their own sites found no cover for flood at their suppliers.

Named locations, indirect suppliers and sublimits

The Broad Form uses a schedule that names and describes each dependent location, and unlisted ones are not covered apart from a small miscellaneous locations allowance. In practice insurers ask for first-tier suppliers and customers to be listed. In 2014 an Aon Benfield executive noted the Thai flood zone held about 570 sub-tier manufacturers that were not necessarily named in anyone’s policy.

Limits are the other pressure point. The Broad Form applies the policy’s business income limit to each scheduled location, but broker commentary describes the contingent coverage actually sold as typically carrying low sublimits. Ask for the limit in dollars next to each named location, and whether the waiting period and the period of restoration match the ones on your own premises.

What contingent business income does not cover

It does not cover an electricity, water or internet outage caused by the utility. That is a different endorsement, ISO’s Utility Services – Time Element, which has to be added and scheduled separately and responds to damage at the utility’s own property.

It does not cover a vendor’s software failure or a cloud outage, because nothing physical was damaged. Cyber policies can address that, with their own triggers and waiting periods; the guide on contingent business interruption on a cyber policy covers it. And it does not cover a customer who simply stops buying, or a supplier who raises prices.

Who should ask about it

Ask when one outside business supplies or buys a large share of your income. That includes a restaurant that depends on a single specialty supplier, a retailer in a mall anchored by one large tenant, a manufacturer that gets a key component from one plant, an agency or studio that gets most of its income from one client’s site, and an online seller that fulfills through one warehouse. The test is simple: if that one location burned, how many weeks until your revenue came back?

Businesses with many interchangeable suppliers usually need it less, because replacement is quick and the loss is small. The exposure is concentration.

Which coverage answers which shutdown

Typical results on standard forms. Your policy wording decides the real answer.

  • A fire closes your own building

    Yes, if a covered cause
    Contingent business income
    Not needed
    Something else to check
    Extra expense and ongoing payroll
  • A fire destroys your only produce supplier’s warehouse

    Your own business income
    No, not your property
    Contingent business income
    Yes, if the supplier is named and the cause is covered
    Something else to check
    Alternate suppliers and the limit per location
  • The anchor store in your center burns and foot traffic drops

    Your own business income
    No
    Contingent business income

    Your own business income
    No
    Contingent business income
    Generally no, no physical loss
    Something else to check
    Read any civil authority wording

Dependent property cover does not respond to a cause your own policy excludes.

The detail

What this means for you

  • List the three outside businesses your income hangs on. One supplier, one customer, one site that draws traffic. Those are your candidates for the schedule.
  • Ask whether dependent properties is on the policy at all. It is an endorsement, not part of the standard business income form, and it is often absent unless requested.
  • Ask what triggers it. Check whether it covers every cause your own policy covers or only a short list, whether it needs named locations, and whether indirect suppliers are excluded.
  • Get the limit in dollars, per location. Compare it with weeks of lost profit and continuing payroll, not with the premium.
  • Do not assume a closure or a recall counts. The trigger is physical damage at the other business. A supplier that stops for any other reason is a different problem.

Related questions

Is contingent business income the same as contingent business interruption?

Yes. The names are used interchangeably, and the ISO forms call it business income from dependent properties. They all mean coverage for income you lose when a supplier, customer or draw location you depend on is physically damaged.

Is contingent business income the same as contingent bodily injury?

No. They share the initials CBI and nothing else. Contingent business income is property coverage for lost earnings when somebody else’s building is damaged. Contingent bodily injury is liability coverage for a person hurt because they relied on your product or advice.

Bodily injury against contingent bodily injury
Does regular business interruption insurance cover a supplier shutdown?

Not on its own. Standard business income coverage responds to damage at your own covered premises. A supplier’s damaged building needs a dependent properties endorsement, and the supplier usually has to be named on it.

Basic, broad and special causes of loss forms
Does it cover a power outage or an internet outage?

Not under the dependent properties forms, which do not treat utility companies as dependent properties. A separate utility services time element endorsement can add it, and it responds to damage at the utility’s property, not to every outage.

Does it cover a cloud or software outage at a vendor?

No. Nothing physical was damaged, so a property endorsement does not respond. Some cyber policies cover income lost to a vendor’s outage, subject to a waiting period and the policy’s trigger.

Contingent business interruption on a cyber policy
Did COVID-19 trigger contingent business income?

Rarely. Most US courts held that the virus or a closure order was not direct physical loss, which is the trigger for these forms too. Wording and state law vary, so a specific claim needs a specific read.

What does it cost?

We do not publish a range, because it depends on how many locations are named, the limit and the causes of loss it follows. It is usually added as an endorsement to a commercial property policy rather than bought on its own.
