3.3 Commercial General Liability (CGL) Coverages & Triggers

Key Takeaways

  • Coverage A (Bodily Injury and Property Damage) excludes expected or intended injury, liquor liability, and pollution, among others.
  • Coverage B (Personal and Advertising Injury) addresses offenses like libel, slander, false arrest, and copyright infringement.
  • The Claims-Made trigger requires the claim to be made during the policy period (or extended reporting period) and the occurrence must happen on or after the retroactive date.
  • The Basic Extended Reporting Period (BERP) provides 60 days to report a claim and 5 years of coverage for claims arising from occurrences reported during that 60-day window.

Commercial General Liability (CGL) Coverages & Triggers

Quick Answer: The Commercial General Liability (CGL) policy shields businesses from third-party liability exposures. It contains Coverage A (Bodily Injury/Property Damage), Coverage B (Personal/Advertising Injury), and Coverage C (Medical Payments). Adjusters must carefully distinguish between the Occurrence form and the Claims-Made form, as the coverage trigger completely alters how coverage is determined.

Every business, from a local bakery to a massive construction firm, faces liability exposures. Customers can slip and fall, products can cause injury, and advertising campaigns can inadvertently infringe on copyrights. The Commercial General Liability (CGL) policy is designed to cover these wide-ranging third-party hazards.

CGL Coverage Sections

The standard CGL policy is divided into three primary coverage parts.

Coverage A: Bodily Injury and Property Damage Liability

This is the core of the CGL. It pays those sums the insured becomes legally obligated to pay as damages because of bodily injury (BI) or property damage (PD) to which the insurance applies. The injury or damage must be caused by an "occurrence" (an accident, including continuous or repeated exposure to substantially the same general harmful conditions).

Coverage A addresses several key exposures:

  • Premises and Operations: Liability arising from the insured's physical location or ongoing work (e.g., a customer slips on a wet floor in a retail store).
  • Products and Completed Operations: Liability arising from the insured's products after they have left the insured's control, or from completed work (e.g., a deck built by a contractor collapses three months after completion, injuring the homeowner).

Key Exclusions to Coverage A:

  • Expected or intended injury.
  • Liquor liability (for businesses in the business of manufacturing, distributing, or selling alcohol).
  • Workers' compensation and employers' liability (covered under a separate policy).
  • Pollution (requires specialized coverage).
  • Care, Custody, or Control (property damage to property in the insured's care, custody, or control is excluded).

Coverage B: Personal and Advertising Injury Liability

Unlike Coverage A, which deals with physical injuries or property damage, Coverage B addresses offenses that cause reputational, emotional, or financial harm. Covered offenses include:

  • False arrest, detention, or imprisonment.
  • Malicious prosecution.
  • Wrongful eviction.
  • Libel or slander (defamation).
  • Use of another's advertising idea.
  • Infringement of copyright, trade dress, or slogan.

Coverage C: Medical Payments

Similar to Part B in a personal auto policy, Coverage C provides goodwill, no-fault medical payments for injuries sustained by third parties on the insured's premises or because of the insured's operations. Payments must be for expenses incurred and reported within 1 year of the date of the accident.

The Coverage Triggers: Occurrence vs. Claims-Made

The most challenging aspect of the CGL for many claims adjusters is determining which policy responds when an injury occurs over time or when a claim is filed long after the incident. This depends entirely on the coverage trigger form used.

The Occurrence Form

The Occurrence form is the most common and the simplest to understand. Coverage is triggered if the bodily injury or property damage occurs during the policy period, regardless of when the claim is actually filed against the insured.

For example, if an electrician installs wiring in 2024 while holding an Occurrence policy, and that wiring causes a fire in 2028 (when the electrician is insured by a different company), the 2028 policy responds because that is when the property damage occurred.

The Claims-Made Form

Certain industries, like medical products manufacturers or environmental contractors, face "long-tail" claims where injuries manifest years later. For these risks, insurers use the Claims-Made form.

For coverage to apply under a Claims-Made form, two conditions must be met:

  1. The claim must be made (reported) during the policy period (or an extended reporting period).
  2. The actual occurrence (the injury or damage) must have happened on or after the retroactive date listed in the policy.

The retroactive date is a critical mechanism. It prevents the policy from covering occurrences that happened before a specified date, effectively capping the insurer's backward-looking exposure.

Extended Reporting Periods (Tail Coverage)

When a Claims-Made policy is cancelled, non-renewed, or replaced by an occurrence form, the insured has a major gap in coverage. To fix this, the policy includes Extended Reporting Periods (ERPs), often called "tail coverage," which extend the time a claim can be reported (they do not extend the policy period or cover new occurrences).

Basic Extended Reporting Period (BERP): This is provided automatically and free of charge when a claims-made policy is cancelled or not renewed. It provides:

  • A 60-day mini-tail to report claims for occurrences that happened during the policy period.
  • A 5-year midi-tail for claims arising from occurrences that were reported to the insurer within that 60-day window.

Supplemental Extended Reporting Period (SERP): If the BERP is insufficient, the insured can purchase a SERP (often called full tail coverage). It provides an unlimited duration to report claims for occurrences that happened between the retroactive date and policy expiration. The SERP must be purchased, often costing up to 200% of the annual premium.

Limits of Insurance

CGL policies have multiple limits that interlock:

  • General Aggregate Limit: The absolute maximum the policy will pay for the sum of all Coverage A, B, and C claims during the policy period (excluding products-completed operations).
  • Products-Completed Operations Aggregate Limit: A separate maximum limit specifically for products and completed operations claims.
  • Each Occurrence Limit: The maximum paid for any one single occurrence.
  • Personal and Advertising Injury Limit: The maximum paid for any one person or organization under Coverage B.

Understanding exactly how these limits apply and are depleted is a fundamental skill for commercial claims adjusters.
