11.3 Key CGL Exclusions and Endorsements

Key Takeaways

  • CGL Coverage A exclusions route specific exposures elsewhere: employee injury to workers' comp, auto/aircraft to commercial auto/aviation, and pollution to specialty pollution policies.
  • The property-damage exclusions (j-n) keep the CGL from acting as a warranty on the insured's own product (k), own work (l), or property in its care (j).
  • Exclusion (l) Damage to Your Work has a subcontractor carve-back, so a GC's CGL can respond to completed-operations damage caused by a subcontractor's faulty work.
  • CG 20 10 adds an additional insured for ongoing operations while CG 20 37 adds completed-operations status; the two are usually paired.
  • CG 25 03 gives each designated construction project its own General Aggregate so one bad job cannot exhaust the limit for all other projects.

Coverage A Exclusions (a) through (q)

The ISO CG 00 01 04 13 Coverage A insuring agreement is broad, then narrowed by exclusions (a) through (q). Exam questions rarely ask you to recite the letters; they test whether you can recognize that a loss falls into a named exclusion and route it to a different policy (auto, workers' comp, pollution, professional liability). Group them by purpose:

  • Expected/intended injury (a) - no coverage for harm the insured expected or intended (except reasonable force to protect persons/property).
  • Contractual liability (b) - excludes assumed liability, but carves back liability you'd have without the contract and liability under an insured contract.
  • Liquor liability (c) - applies only if the insured is in the business of selling/serving alcohol; host liquor liability stays covered.
  • Workers' comp / employers liability (d)(e) - injury to employees in the course of employment routes to WC.

The Property-Damage Exclusions (j) through (n)

These are the most heavily tested because they police the line between liability insurance and property/warranty coverage. The CGL is not a guarantee of the insured's own work or product.

ExclusionExcludes damage to...Why
(j) Damage to PropertyProperty in the insured's care, custody, or control (CCC); the particular part being worked onThat is a bailee/inland-marine exposure
(k) Damage to Your ProductThe insured's own productA warranty risk, not liability
(l) Damage to Your WorkThe insured's completed work ("your work")Repair-your-own-mistake is not insurable liability
(m) Impaired PropertyLoss of use of non-physically-injured property from a defect in the insured's product/workPure economic/recall-type loss
(n) Recall ("Sistership")Cost to recall/withdraw the insured's productCatastrophic recall expense

The Subcontractor Carve-Back ("Your Work" Exception)

Exclusion (l) Damage to Your Work contains the single most tested carve-back in commercial lines: it does not apply if the damaged work, or the work out of which the damage arises, was performed by a subcontractor on the insured's behalf. So a general contractor's CGL can pay for completed-operations damage caused by a sub's faulty work, but not for the GC's own self-performed defective work. This is why GCs require subs to carry CGL and name the GC as additional insured - to pull the sub's policy in as primary.

Major CGL Coverage A Exclusions

The CGL excludes a tested list of exposures, many of which are insured elsewhere:

ExclusionWhy / where covered instead
Expected or intended injuryNot fortuitous (a-exclusion)
Contractual liabilityExcept "insured contracts" (leases, agreements to indemnify)
Liquor liabilityNeeds separate liquor-liability policy if "in the business"
Workers comp / employers liabilityCovered by WC policy
PollutionNeeds environmental/pollution policy
Aircraft, auto, watercraftCovered by auto/aviation/marine
Damage to your product / your work"Business risk" - quality is the insured's job
Damage to property in your care/custody/controlBailee or inland marine
Recall of products ("sistership")Recall insurance

The "Your Work / Your Product" Business-Risk Exclusions

The CGL is not a performance bond: it excludes damage to the insured's own product or work (so an insured cannot use it to redo a bad job), but it does cover consequential property damage to others caused by the faulty work or product - the products-completed operations exposure.

Common CGL Endorsements

  • Additional Insured (CG 20 10/20 37) - adds owners, lessees, contractors.
  • Primary and Noncontributory - makes the policy primary for the additional insured.
  • Waiver of Subrogation - gives up recovery rights against a named party.
  • Amendment of Limits / Designated Premises - tailors scope.

Worked Example

An HVAC contractor wires a unit incorrectly; the unit itself is ruined ($8,000) and the resulting electrical fire damages the customer's building ($120,000). The damage to "your work" (the HVAC unit) is excluded - the CGL will not pay the $8,000 to redo the contractor's own job. But the $120,000 fire damage to the customer's building is covered as products-completed operations property damage to a third party. This split - excluded self-damage vs. covered consequential third-party damage - is the classic business-risk exclusion question.

Test Your Knowledge

A general contractor's completed building suffers water damage because a plumbing SUBCONTRACTOR installed a pipe incorrectly. Under the GC's CGL (CG 00 01 04 13), is the resulting damage to other parts of the building covered?

Pollution, Auto, Aircraft, and War Exclusions

Several exclusions exist to push exposures onto specialty policies:

  • (f) Pollution - the broad "absolute" pollution exclusion bars BI/PD from release of pollutants; buy back via a Pollution Liability policy or CG 00 01 hostile-fire/heat exceptions.
  • (g) Aircraft/Auto/Watercraft - liability arising from owned/operated autos, aircraft, or large watercraft routes to Commercial Auto (CA 00 01) or aviation/marine forms; small watercraft and parking exceptions apply.
  • (h) Mobile Equipment - transport by auto and use in prearranged racing excluded.
  • (i) War - excludes war, including undeclared war and terrorism handled separately (TRIA endorsement).
  • (o) Personal & Advertising Injury under Coverage A - P&AI is Coverage B, not Coverage A.

Common Modifying Endorsements

EndorsementISO formEffect
Additional Insured - Owners, Lessees or Contractors (Scheduled)CG 20 10Adds a party as AI for ongoing operations
Additional Insured - Completed OperationsCG 20 37Adds AI for products-completed operations (pair with CG 20 10)
Amendment of Limits / Designated Construction Project AggregateCG 25 03Gives each project its own General Aggregate
Waiver of Transfer of Rights (Waiver of Subrogation)CG 24 04Insurer waives subrogation against a named party
Primary and NoncontributoryCG 20 01Makes the policy primary over the AI's own coverage

The Designated Construction Project Aggregate (CG 25 03) is heavily tested: without it, all of a contractor's projects share one $2,000,000 General Aggregate; with it, each project gets its own aggregate so a single bad job cannot exhaust the limit for every other site.

Coverage B and Coverage C Exclusions

Coverage B (Personal & Advertising Injury) has its own exclusion list. It excludes injury the insured knew was false, statements made before the policy period, injury arising from breach of contract, and injury from the insured's wrong description of price of goods. P&AI offenses that are covered include false arrest, malicious prosecution, wrongful eviction, slander/libel, and infringing on another's advertising idea or slogan — but not patent or trade-secret infringement.

Coverage C (Medical Payments) is excluded entirely where Coverage A's BI exclusions would apply, and for injury to the insured, employees, tenants, and athletics participants. Knowing which coverage part an exclusion sits under prevents the common error of citing a Coverage A property-damage exclusion to deny an advertising-injury claim.
