7.2 Commercial Causes of Loss Forms, Vacancy & Commercial Property Endorsements

Core Principle: In commercial property insurance, the coverage form (such as the CP 00 10) defines what property is insured, but the Causes of Loss Form dictates which perils trigger coverage. ISO provides three standardized causes of loss forms: Basic (CP 10 10), Broad (CP 10 20), and Special (CP 10 30), alongside specialized perils endorsements like the Earthquake and Volcanic Eruption Endorsement (CP 10 40). Determining which form applies, identifying which party bears the legal burden of proof, and enforcing statutory and contractual exclusions (including Anti-Concurrent Causation and Vacancy conditions) represent foundational adjuster competencies.

Detailed Analysis of Causes of Loss Forms

1. Basic Form (CP 10 10) — 11 Named Perils

The Basic Form provides named-perils coverage restricted exclusively to eleven perils:

1. Fire: Combustion resulting in a visible flame or glow. Includes consequential damage from smoke or water used to extinguish the blaze.
2. Lightning: Naturally generated atmospheric electrical discharges.
3. Explosion: Includes furnace explosion, gas explosion, or rupturing of pressure relief devices. Excludes bursting of steam boilers, pipes, or rotating machinery owned or operated by the insured.
4. Windstorm or Hail: Damage caused by wind or hail. Interior Rain Restriction: Damage to the interior of a building or personal property inside is covered only if the roof or exterior walls first sustain direct physical damage by wind or hail, creating an opening through which rain, snow, sand, or dust enters.
5. Smoke: Sudden and accidental smoke damage. Excludes smoke from agricultural smudging or industrial operations.
6. Aircraft or Vehicles: Direct physical contact by aircraft, spacecraft, or land vehicles, or objects falling from them. Excludes damage caused by vehicles owned or operated by the insured in the course of business.
7. Riot or Civil Commotion: Includes acts of striking employees and looting during a riot.
8. Vandalism: Willful and malicious damage to or destruction of covered property. Excludes theft, but covers building damage caused during a burglary or break-in.
9. Sprinkler Leakage: Leakage or discharge of water or other substances from an automatic sprinkler system, including collapse of a sprinkler tank.
10. Sinkhole Collapse: Sudden settlement or collapse of earth into subterranean cavities created by the action of water on limestone or dolomite. Does not cover the value of the land or man-made underground cavities.
11. Volcanic Action: Direct damage from volcanic blast, airborne shockwaves, ash, dust, or lava flow. All volcanic eruptions occurring within a 168-hour window (7 consecutive days) are deemed a single occurrence. Excludes earthquake or earth tremor.

2. Broad Form (CP 10 20) — Broad Perils & Collapse

The Broad Form includes all 11 Basic perils, plus three additional named perils and one major Additional Coverage:

• Falling Objects: Direct physical damage from falling objects (such as tree branches or falling debris). Like windstorm, damage to the interior of a building or contents inside is covered only if the falling object first breaches the exterior roof or walls.
• Weight of Snow, Ice, or Sleet: Structural collapse or physical damage caused by the accumulated weight of snow, ice, or sleet on a roof.
• Water Damage: Accidental discharge or leakage of water or steam as the direct result of the breaking apart or cracking of a plumbing, heating, air conditioning, or household appliance system.
  • Excludes continuous or repeated seepage or leakage of water occurring over a period of 14 days or more.
  • Excludes the cost of repairing the defect in the appliance or pipe that caused the leak.
  • Excludes flood, backup of sewers or drains, and underground water pressure.
• Additional Coverage — Collapse: Covers abrupt falling down or caving in of a building or any part of a building, resulting in loss of structural integrity such that the building cannot be occupied. The collapse must be caused by specified perils, hidden insect/vermin decay, weight of people or personal property, weight of rain collecting on a roof, or use of defective materials during construction (if construction is underway).

3. Special Form (CP 10 30) — Open Perils & Limitations

The Special Form covers direct physical loss unless excluded or limited. Instead of looking for an affirmative named peril, the adjuster inspects the policy to determine whether an exclusion or limitation bars coverage.

Specific Exclusions Unique to the Special Form

Because the Special Form provides open perils protection, it incorporates specific exclusions to eliminate coverage for wear-related, operational, or business hazards:

• Wear and tear, deterioration, rust, corrosion, decay, or hidden latent defects.
• Smog, industrial smoke, and agricultural chemical spraying.
• Settling, cracking, shrinking, or expansion of pavements, foundations, walls, floors, or roofs.
• Continuous or repeated seepage or leakage of water occurring over 14 days or more.
• Mechanical breakdown, including rupture or bursting caused by centrifugal force.
• Dishonest or criminal acts by the insured, partners, employees, directors, or authorized representatives (employee theft must be insured under Commercial Crime).
• Voluntary parting with property induced by fraudulent schemes, trickery, or false pretenses.
• Rain, snow, ice, or sleet to personal property in the open.
• Inventory shortage or unexplained disappearance: Loss discovered strictly upon taking inventory or stock counts without verifiable physical evidence of theft.

The Earthquake and Volcanic Eruption Endorsement (CP 10 40)

Earthquake and volcanic eruption are strictly excluded under all three standard ISO causes of loss forms by the Earth Movement Anti-Concurrent Causation exclusion. To obtain coverage, commercial policyholders must attach the Earthquake and Volcanic Eruption Endorsement (CP 10 40).

Key Mechanics of CP 10 40

1. Perils Insured: Covers direct physical loss caused by earthquake shocks, earth tremors, and volcanic eruption, explosion, or effusion.
2. The 168-Hour Occurrence Rule: All earthquake shocks or volcanic tremors occurring within any 168-hour consecutive window (7 calendar days) are legally deemed a single occurrence / single loss event. This rule prevents policyholders from having to satisfy multiple deductibles when foreshocks, mainshocks, and aftershocks strike within a one-week period.
3. Percentage Deductible Structure: Unlike the flat dollar deductible used for standard fire or wind losses, earthquake deductibles are structured as a percentage (typically 5%, 10%, or 15%) of the value of the property exposed to loss.
   • Applied separately to each building, to personal property at each building, and to personal property in the open.
   • The deductible dollar amount is calculated by multiplying the percentage by the insurable value of the property (or policy limit, depending on endorsement wording) at the time of loss, not the loss amount itself.
4. Masonry Veneer Limitation: Stucco or brick veneer walls are frequently excluded or subject to specialized sublimits unless specifically scheduled on the endorsement.

The Anti-Concurrent Causation (ACC) Clause

A critical legal concept in commercial property adjusting is the Anti-Concurrent Causation (ACC) clause. Introduced into ISO forms to combat court rulings that favored policyholders when covered and non-covered perils acted together, the ACC lead-in preamble states:

"We will not pay for loss or damage caused directly or indirectly by any of the following. Such loss or damage is excluded regardless of any other cause or event that contributes concurrently or in any sequence to the loss."

Under this language, if an excluded cause of loss and a covered cause of loss combine concurrently or in a sequence of events to produce damage, the damage attributable to the excluded cause is strictly barred from coverage.

The Eight Core ACC Exclusions

1. Ordinance or Law: Enforcement of any municipal or state building code, ordinance, or law regulating the demolition, construction, or repair of structures.
2. Earth Movement: Earthquakes, landslides, mine subsidence, mudslides, earth sinking, rising, or shifting (other than covered sinkhole collapse).
3. Governmental Action: Seizure or destruction of property by order of governmental authority (except destruction ordered to prevent the spread of a fire).
4. Nuclear Hazard: Nuclear reaction, radiation, or radioactive contamination.
5. Utility Services: The failure of power, communication, water, sewer, or gas services originating away from the described premises.
6. War and Military Action: War, undeclared war, civil war, insurrection, rebellion, or military warlike action.
7. Water: Comprehensive flood exclusion covering: (a) Flood, surface water, waves, tidal water, storm surge, or overflow of any body of water; (b) Mudslide or mudflow; (c) Water that backs up or overflows from a sewer, drain, or sump; (d) Subsurface water exerting hydrostatic pressure on foundations, basements, or retaining walls.
8. "Fungus", Wet Rot, Dry Rot, and Bacteria: Mold and fungal growth, with a limited aggregate coverage amount of $15,000 for mold resulting from a covered peril.

Commercial Property Endorsements on the Series 204 Outline

The Commercial Property Vacancy Condition

The Vacancy Condition is a frequently tested commercial property provision. When a commercial building remains unoccupied, the risk of unmitigated vandalism, water intrusion, and undetected fire escalates dramatically.

Definition of Vacancy

The CP 00 10 establishes separate vacancy definitions based on whether the insured is a building owner or a tenant:

• For a Building Owner or General Lessee: A building is considered vacant unless at least 31% of its total square footage is rented to a lessee and used by that lessee to conduct customary operations, or used by the building owner to conduct customary operations.
• For a Tenant: A leased space is considered vacant when it does not contain enough business personal property to conduct customary operations.
• Safe Harbor Exception: Buildings under active construction or undergoing substantial renovation are explicitly not considered vacant, regardless of occupancy percentage.

The 60-Day Vacancy Rules & Penalties

If the described building has been vacant for more than 60 consecutive days immediately preceding the date of direct physical loss or damage:

1. Complete Exclusion (0% Paid)

The insurer will pay absolutely nothing ($0) if the loss or damage is caused by any of the following perils:

• Vandalism
• Sprinkler Leakage (unless the insured has protected the system against freezing)
• Building Glass Breakage
• Water Damage
• Theft or Attempted Theft

2. Mandatory 15% Reduction for All Other Perils

For any covered peril other than those listed above (such as fire, lightning, windstorm, hail, aircraft, or explosion):

• The amount the insurer would otherwise pay for the loss is reduced by 15%.
• The insured receives only 85% of the payable covered loss amount after applying the policy deductible.

Practical Adjuster Claims Scenarios

Scenario 1: Vacant Commercial Office Fire & Vandalism

A strip center owner has an office building insured for $500,000 with a $1,000 deductible under a CP 10 30 Special Causes of Loss form. The tenant vacated the premises on January 1. On March 15 (73 consecutive days later), intruders enter the building, break two plate glass windows, spray graffiti (causing $5,000 in vandalism and glass damage), and start an accidental trash fire that causes $100,000 in structural damage.

• Step 1: Check Vacancy Status: The building was 100% unoccupied for 73 consecutive days, which exceeds the 60-day vacancy threshold.
• Step 2: Segregate by Peril:
  • Vandalism and Glass Breakage ($5,000): 100% excluded ($0 paid) under the vacancy condition.
  • Fire ($100,000): Subject to the mandatory 15% penalty reduction.
• Step 3: Calculate Claim Payment:
  • Covered Fire Loss = $100,000
  • Less Deductible: $100,000 - $1,000 = $99,000
  • Less 15% Vacancy Reduction: $99,000 * 0.85 = $84,150
• Adjuster Result: The insurer pays $84,150. The CP 00 10 applies the deductible and then reduces the amount the insurer would otherwise pay by 15%. The insured absorbs the $5,000 vandalism and glass loss, the $1,000 deductible and the $14,850 vacancy reduction ($20,850 total).

Scenario 2: Hurricane Concurrent Causation in Coastal Louisiana

A commercial warehouse in Houma, Louisiana, is struck by a major Category 3 hurricane. The wind rips off a section of the metal roof (covered peril), allowing $30,000 in rain damage to interior stock. Concurrently, an 8-foot storm surge pushes floodwater through the warehouse doors (excluded peril under Water ACC exclusion), contaminating $70,000 of ground-level inventory.

• Adjuster Analysis: Under the Anti-Concurrent Causation preamble of the CP 10 30 form, flood and storm surge are strictly excluded, even though the hurricane wind was a concurrent contributing factor. The adjuster inspects the physical waterline and segregates the damages:
  • Wind-driven rain entering through the breached roof ($30,000) is covered.
  • Storm surge inundation ($70,000) is excluded under the ACC Water exclusion.
  • Payout: $30,000 minus the applicable deductible.

Scenario 3: Earthquake Swarm under CP 10 40 with 10% Deductible

A commercial manufacturing plant valued at $2,000,000 carries a CP 00 10 with an Earthquake and Volcanic Eruption Endorsement (CP 10 40) featuring a 10% percentage deductible. On Tuesday at 2:00 PM, a 5.8 magnitude earthquake causes $150,000 in structural cracking. On Thursday (48 hours later), a 5.2 magnitude aftershock causes an additional $100,000 in damage.

• Application of 168-Hour Rule: Because both seismic shocks occurred within 168 consecutive hours (48 hours apart), they are treated as a single occurrence.
• Deductible Calculation: The 10% deductible is applied to the insurable property value: 10% * $2,000,000 = $200,000 deductible.
• Claim Payment: Total combined loss = $150,000 + $100,000 = $250,000. Applying the single $200,000 deductible results in a net claim payout of $50,000 ($250,000 - $200,000).
