11.3 Key CGL Exclusions and Endorsements

Why Exclusions Define Coverage

The insuring agreement of the CGL is deliberately broad; the exclusions in Coverage A (Section I) carve out the risks the insurer will not assume. Exam writers test exclusions far more than the insuring agreement because that is where claims are actually denied. Memorize the major Coverage A exclusions, lettered (a) through (q) on CG 00 01.

The Business-Risk Exclusions

The CGL is not a performance bond or warranty. The so-called business-risk exclusions make this explicit:

• Damage to Your Product (k) — the insured's own product that fails is not covered; that is a quality-control cost, not an insurable accident.
• Damage to Your Work (l) — faulty workmanship damaging the insured's own completed work is excluded (subject to a subcontractor exception).
• Damage to Impaired Property (m) — purely economic loss because the insured's product or work is defective or late, where there is no physical injury to other property.

Quick Answer: CGL pays when the insured's faulty work injures someone else's person or property — not to repair or replace the insured's own defective work or product. That is a business risk the insured must bear.

Worked scenario: A roofer installs a roof that leaks. Rainwater ruins the building owner's expensive inventory.

• Replacing the defective roof itself → excluded (your work).
• Damage to the owner's inventory caused by the leak → covered (third-party property damage). The line between the insured's own work and resulting third-party damage is a classic exam trap.

The Insured-Contract Exception

The contractual-liability exclusion (b) has a major carve-back: it does not apply to liability the insured assumes under an insured contract. Insured contracts include leases of premises, sidetrack agreements, easements, obligations to indemnify a municipality, and — most importantly — the part of any contract where the insured assumes the tort liability of another party (a hold-harmless or indemnification clause). This is why a lease's hold-harmless provision is enforceable under the CGL.

Pollution and Liquor Nuances

The pollution exclusion (f) is broad and bars most environmental claims; insureds with pollution exposure need a separate Pollution Liability or CPL policy. The liquor liability exclusion (c) applies only to insureds in the business of manufacturing, selling, serving, or furnishing alcohol. A business that merely hosts a holiday party retains host liquor liability coverage under the CGL — a frequently tested distinction.

Common Endorsements

Endorsements modify the base form. The most tested are the Additional Insured endorsements, which extend the named insured's coverage to another party (often required by contract):

• CG 20 10 — Additional Insured, owners/lessees/contractors for ongoing operations.
• CG 20 37 — Additional Insured for completed operations (pairs with CG 20 10 for full protection).
• CG 20 26 — Additional Insured, designated person or organization.
• CG 25 03 / CG 25 04 — Designated Construction Project(s) / Designated Location(s) General Aggregate Limit, giving a separate aggregate per project or location so one project's losses do not erode the limit for others.

Trap: an additional insured under CG 20 10 (ongoing ops only) is NOT protected for completed-operations claims arising after the work is finished — the contract should also require CG 20 37.

The Subcontractor Exception to 'Your Work'

The "damage to your work" exclusion (l) contains an important carve-back: it 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 the reason a general contractor's CGL can respond to property damage caused by faulty work a sub performed — without it, completed-operations coverage on construction projects would be largely illusory. Exam questions pair a GC, a defective subcontractor's installation, and resulting damage; the subcontractor exception restores coverage that the bare exclusion would have removed.

Pollution Exclusion Carve-Backs

The broad pollution exclusion (f) has limited exceptions. Coverage may survive for bodily injury from heat, smoke, or fumes of a hostile fire, and for certain building-heating-equipment fume claims. True environmental exposures — gradual seepage, cleanup orders, discharge of contaminants — require a separate Pollution Legal Liability (PLL) or Contractors Pollution Liability (CPL) policy. Do not expect the standard CGL to fund a cleanup; that is a classic denied-claim scenario.

Other Frequently Tested Exclusions

Putting It Together

The pattern across CGL exclusions is consistent: the form insures third-party bodily injury and property damage caused by accidents, and excludes (1) the insured's own business risks (your work, your product, impaired property, recall), (2) exposures meant for specialty lines (auto, watercraft, aircraft, pollution, professional, employment, cyber), and (3) intentional or contractual liabilities except where a carve-back restores them. When a question describes a denial, trace it to one of these three categories and the answer follows.
