11.3 Key CGL Exclusions and Endorsements
Key Takeaways
- Coverage A lists 14 exclusions; the CGL is third-party liability for accidental loss - not a warranty of the insured's own product or work, and not a substitute for WC or auto coverage.
- The 'business risk' exclusions (j-m) bar paying to fix the insured's own defective product or work; exclusion (l) has a key exception for work performed by a subcontractor.
- The pollution exclusion (f) is broad and usually requires a separate environmental policy; the contractual liability exclusion (b) preserves sole tort liability and 'insured contracts.'
- Additional Insured (CG 20 10/20 37), Waiver of Subrogation (CG 24 04), and Primary & Noncontributory endorsements are commonly required by contract.
- CG 25 03 (per-project) and CG 25 04 (per-location) endorsements give each project or location its own General Aggregate so one loss cannot drain coverage for the others.
Coverage A Exclusions: What the CGL Does Not Pay
Section I, Coverage A of ISO CG 00 01 lists fourteen exclusions (a) through (n). Exam questions cluster around the handful that producers must explain to commercial clients. The unifying theme: the CGL is a third-party liability form for accidental injury and damage - it is not a guarantee of the insured's own work product and not a substitute for workers compensation or auto coverage.
The most-tested Coverage A exclusions:
| Exclusion | What it removes | Why / common substitute coverage |
|---|---|---|
| (a) Expected or Intended Injury | Intentional harm by the insured | Liability insures fortuitous loss, not deliberate acts; self-defense exception |
| (b) Contractual Liability | Liability assumed by contract | Exception preserves "insured contracts" and tort liability that would exist anyway |
| (d) Workers Compensation | Obligations under WC/disability laws | Workers Comp policy |
| (e) Employer's Liability | BI to an employee in the course of employment | Part Two of the Workers Comp policy |
| (f) Pollution | Most pollution release/cleanup | Separate Pollution/Environmental policy |
| (g) Aircraft, Auto, Watercraft | Liability from owned auto/aircraft/large watercraft | Business Auto / Aircraft / Marine policies |
| (j) Damage to Property | Insured's own property, property in care/custody/control | Property policy; installation/builders risk |
| (k) Damage to Your Product | The insured's own product | This is a business risk, not insurable liability |
| (l) Damage to Your Work | The insured's own completed work | Exception: work by a subcontractor |
| (m) Impaired Property | Loss of use of non-damaged property from a defect | Performance bond / business risk |
The "Business Risk" Exclusions (j, k, l, m)
Exclusions (j) through (m) are collectively the "business risk" or "your work/your product" exclusions and are among the most misunderstood on the exam. The principle: the CGL covers damage the insured's faulty work causes to someone else's property or person, but not the cost to repair or replace the insured's own defective product or work. Fixing your own bad work is a cost of doing business, not an insurable liability.
Key exception: exclusion (l) Damage to Your Work does not apply if the damaged work, or the work out of which the damage arises, was performed by a subcontractor. This subcontractor exception is what makes the CGL valuable to general contractors.
A general contractor's CGL is asked to pay to rip out and replace defective concrete that the contractor's own crew poured. Why is this typically NOT covered?
Pollution and Contractual Liability Traps
The pollution exclusion (f) is broad: it eliminates BI/PD from the actual or threatened discharge, dispersal, or escape of pollutants, and also the cost to clean up or test for pollutants. Limited exceptions exist (e.g., a building heating-equipment hostile-fire exception). Pollution exposures require a separate environmental/CPL policy.
The contractual liability exclusion (b) removes liability the insured assumes by contract - but its exception preserves coverage for (1) liability the insured would have without the contract (sole tort liability), and (2) liability assumed under an "insured contract" such as a lease, easement, or sidetrack agreement. This is why hold-harmless and indemnity wording matters on the exam.
Common Endorsements That Modify the CGL
Producers tailor the CGL with endorsements. The most frequently tested:
- Additional Insured endorsements (CG 20 series): add a party (landlord, lender, customer) as an insured for liability arising from the named insured's work - e.g., CG 20 10 (ongoing operations) and CG 20 37 (completed operations).
- Waiver of Transfer of Rights / Waiver of Subrogation (CG 24 04): the insured waives the insurer's right to recover from a designated party, usually required by contract.
- Primary and Noncontributory: requires the CGL to pay first and not seek contribution from the additional insured's own policy.
- Designated Premises/Project (CG 21 44): limits coverage to a specific location or job.
Per-Project / Per-Location Aggregate Endorsements
Because a single shared General Aggregate can be exhausted by one large project, contractors frequently add:
- Designated Construction Project(s) General Aggregate Limit (CG 25 03): gives each project its own General Aggregate.
- Designated Location(s) General Aggregate Limit (CG 25 04): gives each location its own General Aggregate.
Worked example: A contractor with a $2,000,000 General Aggregate runs five simultaneous projects. Without the endorsement, one project's claims could consume the entire $2M, leaving the other four with nothing. With CG 25 03, each of the five projects carries its own $2,000,000 aggregate - up to $10,000,000 of aggregate protection across the projects - which is exactly why owners often require it in their contracts.
A contractor is required by an owner to ensure that claims on one job site cannot exhaust the aggregate available to other job sites. Which endorsement accomplishes this?
Additional Insured and Primary-and-Noncontributory Endorsements
Contracts routinely require a party to add another as an additional insured on its CGL (e.g., a subcontractor adds the general contractor) and to make that coverage primary and noncontributory so the additional insured's own CGL is not tapped first.
Common endorsements: CG 20 10 (additional insured — owners/lessees/contractors, ongoing operations) and CG 20 37 (completed operations); a waiver of subrogation endorsement bars the insurer from pursuing the protected party. The exam ties these to the indemnity/hold-harmless agreements in Chapter 8: the contract shifts liability, and these endorsements fund the shift with the subcontractor's insurance.
The 'Your Work' / 'Your Product' Business-Risk Logic
The CGL is not a performance warranty: exclusions (j)–(n) remove damage to 'your work,' 'your product,' impaired property, and the cost to recall defective products. The policy pays when the insured's faulty work injures a third party or other property (a defective wire causes a building fire), but not the cost to rip out and replace the defective work itself — that is a business risk the contractor must price into the job, not transfer to the liability insurer. A subcontractor exception restores coverage for completed-operations damage arising from a sub's work, a key construction-defect nuance.
