11.3 Key CGL Exclusions and Endorsements
Key Takeaways
- CGL exclusions, not the insuring agreement, decide most coverage outcomes; learn them by ISO number pattern (CG 21/22 exclusions, CG 20 additional insureds, CG 24 buy-backs).
- The 'Damage to Your Product/Your Work' business-risk exclusions bar fixing the insured's own defective product or workmanship, but resulting damage to others' property is covered.
- The absolute pollution exclusion removes nearly all pollution BI/PD; the hostile fire exception and separate Pollution Liability policies are the workarounds.
- CG 20 10 (ongoing) and CG 20 37 (completed ops) add owners/contractors as additional insureds; CG 20 11 adds a landlord; CG 24 04 waives subrogation.
- Most CGL coverage questions follow an exclude-then-buy-back pattern: identify the exclusion first, then check for an exception or endorsement that restores coverage.
Why Exclusions Define the CGL
The CGL insuring agreement is broad, so the exclusions in Section I - Coverage A do most of the underwriting work. Exam questions rarely ask you to recite all exclusions; instead they describe a loss and ask whether it is covered. To answer, you must recognize the named exclusion and any endorsement that buys it back. The two-letter ISO numbering (CG 21 xx, CG 22 xx for exclusions; CG 20 xx for additional insureds; CG 24 xx for buy-backs) is worth memorizing in pattern.
The Major Coverage A Exclusions
| Exclusion | What It Removes | Rationale |
|---|---|---|
| Expected or Intended Injury | Deliberate harm (self-defense excepted) | Fortuity - liability insures accidents |
| Contractual Liability | Liability assumed by contract (insured-contract exception preserved) | Avoid covering bad bargains |
| Liquor Liability | BI/PD if insured is in the liquor business | Needs separate liquor policy |
| Workers' Compensation / Employer's Liability | Injury to employees | Covered by WC policy |
| Pollution | Most pollution release BI/PD | Needs environmental policy |
| Auto/Aircraft/Watercraft | Liability from owned autos, aircraft, large boats | Covered by auto/aviation/marine |
| Damage to Your Product / Your Work | The insured's own product or completed work | Business risk, not insurable liability |
| Damage to Property in Your Care | Property in insured's care, custody, control | Needs installation/bailee coverage |
| Recall (Sistership) | Cost to recall/withdraw the product | Catastrophic business risk |
The Business-Risk Exclusions (Your Product / Your Work)
The most heavily tested exclusions are 'Damage to Your Product' and 'Damage to Your Work.' The CGL is third-party liability insurance - it pays when the insured damages someone else's person or property, not when the insured's own product or workmanship is simply defective.
If a contractor installs a faulty roof and it leaks, repairing the roof itself (your work) is excluded; the resulting water damage to the owner's furniture is covered third-party property damage. Distinguishing the excluded 'cost to fix my work' from the covered 'damage my work caused to other property' is a guaranteed exam item.
An electrician miswires a panel. The faulty panel must be torn out and rewired ($4,000), and the defective wiring also started a fire that destroyed $30,000 of the customer's inventory. Under an unendorsed CGL, what is covered?
The Pollution Exclusion and Its Exceptions
The absolute pollution exclusion removes BI/PD arising from the actual, alleged, or threatened discharge of pollutants. It is broad, but ISO preserves narrow exceptions - notably the hostile fire exception (heat/smoke/fumes from a fire that breaks out where it should not be is covered) and limited building-heating-equipment fumes. Businesses with genuine pollution exposure buy separate Pollution Liability or add a Limited Pollution endorsement; candidates should know the CGL itself essentially zeroes out pollution coverage.
Common Endorsements - Adding and Buying Back
Endorsements modify the base CG 00 01. The exam favors these:
- Additional Insured - Owners, Lessees or Contractors (CG 20 10 / CG 20 37): Extends coverage to a project owner or upstream contractor; CG 20 10 covers ongoing operations, CG 20 37 covers completed operations.
- Additional Insured - Managers or Lessors of Premises (CG 20 11): Names a landlord as additional insured on a tenant's CGL.
- Waiver of Transfer of Rights of Recovery / Subrogation (CG 24 04): Insured waives its insurer's subrogation rights against a named party (common in leases and construction contracts).
- Amendment of Liquor Liability Exclusion (CG 24 08): Buys back limited host-liquor or liquor exposure.
- Primary and Noncontributory (CG 20 01): Makes the named policy pay first without seeking contribution from the additional insured's own coverage.
A landlord requires its tenant to name the landlord as an additional insured on the tenant's CGL for the leased premises. Which endorsement accomplishes this?
Reading the Exclusion-Then-Buy-Back Pattern
The exam's favorite structure is: a base exclusion removes coverage, then an endorsement restores part of it. Liquor liability is excluded for the liquor business but a host-liquor situation may be covered; contractual liability is excluded except for 'insured contracts'; pollution is excluded except for hostile fire. When a question describes a loss, first identify the exclusion, then ask whether an exception or endorsement buys it back. That two-step reasoning - exclude, then restore - is how nearly every CGL coverage question is constructed.
The Business-Risk Exclusions (Your Product / Your Work)
The CGL is not a warranty on the insured's own work. The business-risk exclusions remove: damage to your product (exclusion k), damage to your work arising out of it within the products-completed-ops hazard (exclusion l, with a subcontractor exception restoring coverage when the faulty work was done by a sub), damage to impaired property not physically injured (exclusion m), and recall (sistership) costs (exclusion n). The point the exam tests: the CGL covers resulting damage to other property and third-party injury, but not the cost to fix the insured's own defective product or work.
Defective wiring you installed that burns down the customer's building — the building damage is covered; replacing your faulty wiring is not.
The Pollution Exclusion and Its Carve-Backs
The absolute pollution exclusion bars BI/PD from the discharge, dispersal, or release of pollutants at or from premises, sites, or operations. Limited exceptions exist for hostile fire heat/smoke, certain products-completed-ops off-site releases, and building heating-equipment fumes. True environmental exposure needs a separate Pollution Liability/CPL policy. A stem about a chemical spill contaminating soil is excluded under the base CGL.
Other Key Coverage A Exclusions
Recognize: expected/intended injury, contractual liability (carve-back for insured contracts), liquor liability (for those in the business of serving alcohol — host liquor is covered), workers compensation/employers liability, auto/aircraft/watercraft (use commercial auto or aviation), mobile equipment in racing, war, damage to property in the insured's care/custody/control, and electronic data (not tangible PD).
The Exclusion-Then-Buy-Back Pattern and Common Endorsements
Many exclusions are bought back by endorsement: liquor liability, pollution (limited), employee benefits liability, additional insured status (CG 20 10 ongoing operations, CG 20 37 completed operations), primary and noncontributory wording, and waiver of subrogation. The exam tests the structure: the base form excludes, and an endorsement restores or extends coverage for a premium. When a stem describes a contractor required to name the property owner as an additional insured, identify the CG 20 10 / CG 20 37 endorsements as the mechanism.
