ACORD 126

Commercial General Liability Section

The GL supplement to the ACORD 125. Captures liability limits, classification codes, premises info, and additional insured requirements.

What This Form Is For

The ACORD 126 supplements the 125 with detailed information specific to general liability coverage. If the 125 establishes who the business is, the 126 answers the question: what GL exposure does this business have?

This form captures everything an underwriter needs to rate and write a general liability policy — requested limits, ISO CGL classification codes, premium basis and exposure amounts, premises details, products and completed operations information, and additional insured requirements.

For most commercial accounts, the 126 is submitted alongside the 125 as part of the core application package. The classification information on the 126 directly determines the GL premium, making accuracy here especially important.

Section-by-Section Walkthrough

Fields That Matter Most to Underwriters

  • 1ISO CGL classification code — drives the base rate
  • 2Premium basis exposure (revenue or payroll) — determines premium size
  • 3Products/completed operations — high-severity exposure class
  • 4Loss history (from the 125) — frequency and severity patterns
  • 5Additional insured count — indicates contractual obligations and exposure breadth

Common Mistakes

Wrong classification code

Using the wrong ISO CGL class code results in incorrect premium and can create a coverage gap if a claim falls outside the listed classification. Verify codes against the actual operations, not the business name.

Underreported revenue or payroll

GL premiums are based on revenue or payroll exposure. Underreporting to lower the initial premium creates problems at audit — the carrier will charge the difference, often with audit penalties. Report projected exposure honestly.

Missing additional insureds

If the insured has contracts requiring additional insured status for third parties, list them on the application. Omitting them delays certificate issuance and can put the insured in breach of contract.
