Key Takeaways

  • The Commercial General Liability (CGL) policy is the FOUNDATION of business liability protection, covering third-party bodily injury, property damage, and personal/advertising injury.
  • CGL policies are written on either an OCCURRENCE basis (covers incidents during policy period regardless of when claim is made) or CLAIMS-MADE basis (covers claims made during policy period).
  • The NAMED INSURED includes the business entity, its partners, members, managers, and employees—but only while acting within the scope of their duties.
  • CGL premiums exceeded $50 BILLION annually in the U.S., making it one of the largest commercial insurance lines.
  • Over 75% of CGL claims are related to PREMISES-OPERATIONS liability (slip and fall, customer injuries), not products liability.

CGL Policy Overview

What is Commercial General Liability?

Commercial General Liability (CGL) insurance protects businesses against third-party claims for:

  • Bodily injury (physical harm to non-employees)
  • Property damage (damage to others' property)
  • Personal and advertising injury (defamation, copyright infringement)

Key Concept: CGL covers the insured's legal LIABILITY to others—not damage to the insured's own property (that's commercial property insurance).

CGL Policy Structure

The standard CGL policy (ISO form CG 00 01) contains:

Occurrence vs. Claims-Made

The CGL policy uses one of two coverage triggers:

Occurrence Form

FeatureDetails
TriggerInjury/damage must OCCUR during policy period
When Claim FiledDoesn't matter—can be years later
Tail CoverageBuilt-in (no additional cost)
Best ForMost businesses; provides long-term protection

Example: Policy period is 2024. Customer slips and falls in December 2024 but doesn't file suit until 2026. The 2024 occurrence policy responds.

Claims-Made Form

FeatureDetails
TriggerClaim must be MADE during policy period
Retroactive DateLimits how far back coverage extends
Tail CoverageMust purchase Extended Reporting Period (ERP)
Best ForProfessional liability, products with delayed claims

Example: Policy period is 2024 with retroactive date of 2020. Claim filed in 2024 for injury occurring in 2021 is covered. Claim for 2019 injury is NOT covered.

Who Is An Insured?

The CGL policy covers these persons and organizations:

Named Insured (Listed in Declarations)

Entity TypeWho Is Covered

Partnership/Joint VenturePartners and members
LLCMembers and managers
CorporationOfficers, directors, stockholders, employees
TrustTrustees

Automatic Insureds

CategoryCoverage

Newly Acquired OrganizationsFor 90 days (unless longer specified)

Who Is NOT Automatically Insured

  • Independent contractors (must be added by endorsement)
  • Additional insureds (requires endorsement)
  • Subcontractors (separate policies required)

The Two Duties of the Insurer

1. Duty to Defend

  • Insurer provides and pays for legal defense
  • Applies even if lawsuit is groundless, false, or fraudulent
  • Defense costs are IN ADDITION to policy limits (supplementary payments)
  • Ends when policy limits are exhausted

2. Duty to Indemnify

  • Insurer pays damages the insured is legally obligated to pay
  • Subject to policy limits
  • Only applies when insured is LEGALLY LIABLE

Important: The duty to defend is BROADER than the duty to indemnify. If ANY allegation in the lawsuit COULD be covered, the insurer must defend.

Supplementary Payments

These are paid IN ADDITION to policy limits:

PaymentPurpose
All Defense CostsAttorney fees, court costs, expert witnesses
Bail BondsUp to $250 for traffic law violations
Appeal BondsBond cost and up to $250/day for lost wages
Prejudgment InterestInterest from date of judgment
Post-Judgment InterestAfter judgment, before insurer pays
First Aid ExpensesReasonable first aid costs
