16.5 Closing Coverage Gaps: Equipment Breakdown, Crime, and Builders' Risk

Key Takeaways

  • Equipment breakdown coverage fills the mechanical and electrical breakdown exclusion in commercial property forms and can include business income, spoilage, and expediting expenses.

  • ISO commercial crime forms cover employee theft, forgery or alteration, inside and outside the premises losses, computer and funds transfer fraud, and money orders and counterfeit money.

  • Crime coverage is written on a discovery form or a loss-sustained form, which changes when a loss must occur and when it must be discovered.

  • Social engineering (impersonation) fraud is often excluded from computer and funds transfer fraud coverage and may need a separate endorsement or policy.

  • Builders' risk covers buildings under construction, with the completed value or reporting form approach setting the limit.

Closing Coverage Gaps: Equipment Breakdown, Crime, and Builders' Risk

Quick Answer: Standard commercial property forms exclude or limit several important exposures. Equipment breakdown coverage fills the mechanical and electrical breakdown exclusion. Commercial crime coverage handles employee theft, forgery, robbery, and computer and funds transfer fraud, which property forms exclude or limit. Builders' risk covers buildings under construction. Choosing the right crime form, discovery or loss-sustained, and addressing social engineering fraud are frequent exam and practice issues.

Why These Gaps Exist

Commercial property forms are designed for sudden, external physical damage. They deliberately exclude exposures that need specialized underwriting and inspection, such as boilers, dishonest employees, and construction projects. These exposures are handled by separate coverages with their own conditions.

Equipment Breakdown Coverage

Commercial property forms exclude mechanical breakdown, electrical disturbance to electrical devices, and steam boiler explosion. Equipment breakdown coverage (historically called boiler and machinery) responds to a sudden and accidental breakdown of covered equipment, such as boilers, HVAC systems, electrical panels, production machinery, and computers.

Typical coverageWhat it pays
Property damageRepair or replacement of the equipment and damage it causes to other property
Business income and extra expenseLost income and extra costs while equipment is down
SpoilagePerishable goods spoiled because of the breakdown
Utility interruptionLoss from a breakdown of utility equipment serving the premises
Expediting expensesOvertime labor and express shipping to speed repairs
Hazardous substances and data restorationCleanup and restoring data lost in the breakdown

Equipment breakdown insurers also provide jurisdictional inspections of boilers and pressure vessels, which many states require.

Commercial Crime Coverage

Commercial property forms exclude or sharply limit money, securities, and dishonest acts. ISO commercial crime forms offer several insuring agreements:

Insuring agreementCovers
Employee theftTheft of money, securities, or other property by employees
Forgery or alterationForged or altered checks and similar instruments drawn on the insured's accounts
Inside the premises: theft of money and securitiesTheft, disappearance, or destruction of money and securities on premises
Inside the premises: robbery or safe burglary of other propertyRobbery of a custodian or safe burglary involving other property
Outside the premisesMoney, securities, and other property in the care of a messenger or armored car company
Computer and funds transfer fraudFraudulent computer entries and fraudulent instructions to a financial institution to transfer funds
Money orders and counterfeit moneyAccepting invalid money orders or counterfeit currency in good faith

Discovery vs. Loss-Sustained Forms

FormTrigger
Discovery formCovers loss discovered during the policy period (or an extended period after it), regardless of when the loss occurred, subject to any retroactive date
Loss-sustained formCovers loss sustained during the policy period and discovered during the policy period or within a set period after it ends

Because employee theft often goes on for years before discovery, the choice of form matters most when changing insurers. Without prior-loss provisions, a switch can leave gaps.

Key Crime Conditions

  • Termination as to an employee: Coverage for a specific employee ends as soon as the insured learns of that employee's dishonest act, even one committed before hire.
  • Ownership and custody: Coverage applies to property the insured owns, holds, or is legally liable for.
  • Social engineering fraud: An employee who is tricked into voluntarily wiring funds, for example by a fake vendor email, may not be covered under computer and funds transfer fraud. That agreement generally addresses unauthorized transfers. Businesses often add social engineering (impersonation) fraud coverage by endorsement or through a cyber policy.

Builders' Risk

Buildings under construction face fire, theft of materials, windstorm, and vandalism. Ordinary building coverage does not fit well because values rise throughout construction.

  • Completed value approach: The limit equals the building's full completed value. Premium reflects the average value at risk during construction.
  • Reporting approach: The insured reports values periodically as construction progresses.
  • Who buys it: The owner or the contractor, as the construction contract requires, often naming other parties with interests.
  • Coverage typically ends when the building is occupied or put to its intended use, when it is accepted, or when the owner's interest ends.
  • Common gaps: Soft costs (interest, permits, fees) and delayed-completion income, which are available by endorsement or in manuscript forms.

Worked Scenario: A Wholesale Distributor

A distributor has a $2 million inventory, two large chillers, and a bookkeeper with sole control of payments. Recommendations:

  1. Equipment breakdown with spoilage and expediting expenses for the chillers
  2. Commercial crime with employee theft (a limit sized to cash flows and inventory), forgery or alteration, and computer and funds transfer fraud
  3. Social engineering endorsement, because the bookkeeper wires vendor payments and vendor-impersonation fraud is common
  4. Internal controls as risk control: dual approval for wires, callback verification of changed bank details, and mandatory vacations

Common Traps

  • Assuming property forms cover machinery breakdown: They exclude it; equipment breakdown coverage is needed.
  • Choosing the wrong crime form when switching insurers: Discovery and loss-sustained forms treat prior losses differently.
  • Expecting social engineering coverage automatically: It usually requires a specific endorsement or policy.
  • Forgetting soft costs in construction: Builders' risk forms often need endorsements for soft costs and delayed completion.

Claims-made liability form

C

Test Your Knowledge

An accounts payable clerk receives a convincing email from a fake vendor asking to change bank details and wires $85,000 to the fraudster. Why might standard computer and funds transfer fraud coverage not respond?

A

Because money is never covered under crime forms

B

Because the loss is below the minimum deductible for crime coverage

C

Because the clerk voluntarily made an authorized transfer after being deceived, which is generally treated as social engineering fraud needing separate coverage

D

Because employee theft always applies instead
