CGL Policies: Occurrence vs. Claims-Made Forms

In the world of commercial insurance, the Commercial General Liability (CGL) policy is the bedrock of protection for businesses. For an adjuster, one of the most critical concepts to master is the "trigger of coverage." A trigger is the specific event or condition that must occur for a liability policy to respond to a claim.

CGL policies are written on one of two primary forms: the Occurrence Form or the Claims-Made Form. While the coverage for bodily injury and property damage remains largely the same between the two, the timing requirements for when a loss happens and when it is reported differ significantly. Understanding these nuances is essential for passing your exam and accurately processing claims in the field. For a broader overview of exam topics, visit our complete Claims Adjuster exam guide.

The Occurrence Form is the most common version of the CGL policy. Its trigger is straightforward: the policy that was in effect when the bodily injury or property damage occurred is the policy that must pay the claim, regardless of when the claim is actually filed.

This form is particularly beneficial for businesses because it provides "long-tail" coverage. If an accident happens during the policy period, but the injured party does not file a lawsuit until several years later, the original policy still responds. This is true even if the policy has long since expired or been replaced by another carrier.

• Key Advantage: No gaps in coverage for events that happened during the active policy term.
• Adjuster Focus: When investigating an occurrence claim, the adjuster's primary goal is to determine the exact date the damage or injury took place to identify which policy year applies.

The Claims-Made Form was developed to handle risks that are difficult to predict or that may result in claims many years after an event. Under this form, the trigger is dual-natured: the claim must be made against the insured during the policy period, and the occurrence must have happened after a specific date known as the Retroactive Date.

Because the insurer only pays for claims actually reported during the policy year, this form allows for more predictable underwriting. However, it requires careful management of dates to ensure the insured does not lose coverage when switching carriers.

• Retroactive Date: A date listed on the declarations page. The policy will not cover any occurrences that happened before this date, even if the claim is filed during the policy period.
• The Trigger: The claim must be received and recorded by the insured or the insurer during the policy term.

When a Claims-Made policy is cancelled or not renewed, a "gap" can occur where the insured is no longer covered for past events that haven't resulted in a claim yet. To solve this, insurers offer Extended Reporting Periods (ERPs), often called "tail coverage."

There are two main types of ERPs adjusters must know for the exam:

• Basic ERP: Automatically included in the policy. It usually provides a five-year window to report claims for occurrences that were reported to the insurer within 60 days of the policy expiration (often called the "midi-tail"), and a 60-day window for claims where the occurrence was not previously reported (the "mini-tail").
• Supplemental ERP: An optional endorsement the insured can purchase. This provides an unlimited duration for reporting claims. It effectively turns the claims-made protection into something resembling occurrence protection for that specific period.
