14.3 CGL Limits of Insurance & Insured Status

Key Takeaways

  • The standard ISO CGL policy contains six interconnected limits of insurance on the Declarations: General Aggregate Limit, Products-Completed Operations Aggregate Limit, Each Occurrence Limit, Personal and Advertising Injury Limit, Damage to Premises Rented to You Limit, and Medical Expense Limit.
  • The General Aggregate Limit is the maximum payable during a single policy period for all claims under Coverage A (premises and ongoing operations), Coverage B (personal and advertising injury), and Coverage C (medical payments) combined, while the Products-Completed Operations Aggregate functions as an entirely separate, non-eroding aggregate limit.
  • The Each Occurrence Limit caps the insurer's liability for any single accident under Coverage A and Coverage C combined, and any payment under these coverages concurrently erodes the remaining General Aggregate Limit.
  • Section II (Who Is An Insured) establishes insured status based on legal entity structure (sole proprietorship, partnership/joint venture, LLC, corporation, or trust) and automatically includes employees and volunteer workers acting within the scope of their employment, subject to the Fellow Employee Exclusion.
  • The CGL clearly distinguishes between 'Autos' (vehicles designed for public road travel, covered under Commercial Auto) and 'Mobile Equipment' (bulldozers, forklifts, crawler machinery, covered under CGL for jobsite liability and Inland Marine for physical damage).

14.3 CGL Limits of Insurance & Insured Status

Properly adjusting a Commercial General Liability claim requires a precise understanding of the policy's Limits of Insurance architecture and the legal scope of Who Is An Insured under Section II. A claims adjuster must know how payments under one coverage part erode aggregate limits, how supplementary payments apply, who qualifies for defense and indemnity, and how to coordinate coverage between CGL, Commercial Auto, and Inland Marine policies.


1. The CGL Limits of Insurance Architecture

The CGL Declarations page contains six distinct monetary limits of insurance. These limits represent the maximum dollar amounts the insurer will pay, regardless of the number of insureds, claims made, suits brought, or persons/organizations making claims.

Detailed Analysis of the Six CGL Limits

  1. General Aggregate Limit:

    • The maximum total dollar amount payable during the entire policy period for the sum of all damages under Coverage A (except products-completed operations), Coverage B, and Coverage C combined.
    • Once the General Aggregate Limit is exhausted by payment of judgments or settlements, the insurer's obligations under Coverages A, B, and C (including the duty to defend) terminate for the remainder of that policy period.
  2. Products-Completed Operations Aggregate Limit:

    • A completely separate aggregate limit that applies exclusively to bodily injury and property damage included within the "products-completed operations hazard".
    • Critical Claims Principle: Claims arising from defective products or completed work erode only the Products-Completed Operations Aggregate; they do not erode the General Aggregate Limit.
  3. Each Occurrence Limit:

    • The maximum amount payable for any single occurrence (accident) for the sum of all damages under Coverage A (BI & PD) and medical expenses under Coverage C combined.
    • Any payment under the Each Occurrence Limit simultaneously erodes the remaining General Aggregate Limit (or Products-Completed Operations Aggregate if applicable).
  4. Personal and Advertising Injury Limit:

    • The maximum amount payable under Coverage B for the sum of all damages sustained by any one person or organization.
    • Payments under this limit concurrently erode the General Aggregate Limit.
  5. Damage to Premises Rented to You Limit (Fire Damage Legal Liability):

    • A sub-limit under Coverage A (standard ISO base is $100,000 per occurrence) that applies to property damage caused by fire to premises rented to the named insured or temporarily occupied by the named insured with the owner's permission.
    • Also applies to damage caused by any peril to premises (and contents) rented to the insured for 7 or fewer consecutive days.
    • Payments under this sub-limit erode both the Each Occurrence Limit and the General Aggregate Limit.
  6. Medical Expense Limit:

    • A sub-limit under Coverage C (standard ISO base is $5,000 per person) that applies to reasonable medical expenses for bodily injury sustained by any one person in any single accident.
    • Payments under this sub-limit erode both the Each Occurrence Limit and the General Aggregate Limit.

3. Section II: Who Is An Insured

Section II of the CGL policy defines who qualifies as an insured based on the legal entity form under which the business operates, as well as extending coverage to various individuals connected to the business.

1. Entity-Specific Insureds

Legal Entity FormWho Is An Insured Under the CGL Form?
Individual (Sole Proprietorship)The named individual and their spouse, but solely with respect to the conduct of a business of which the named insured is the sole owner.
Partnership or Joint VentureThe named partnership or joint venture, its partners or co-venturers, and their spouses, solely with respect to the conduct of the business. (No person or organization is an insured with respect to past unlisted partnerships/ventures).
Limited Liability Company (LLC)The named LLC, its members (with respect to the conduct of the business), and its managers (with respect to their duties as managers).
Corporation / OrganizationThe named corporation, its executive officers and directors (with respect to their duties as officers/directors), and its stockholders (with respect to their liability as stockholders).
TrustThe named trust and its trustees, solely with respect to their duties as trustees.

2. Operational Insureds (Employees, Managers & Representatives)

In addition to entity owners, Section II extends insured status to:

  1. Employees and Volunteer Workers:

    • Employees and volunteer workers are insureds while acting within the scope of their employment or performing duties related to the conduct of the business.
    • The Fellow Employee Exclusion: Employees and volunteer workers are NOT insureds for:
      • Bodily injury or personal injury to a co-employee while in the course of employment (which must be handled under Workers' Compensation);
      • Bodily injury or personal injury to the spouse, child, parent, or sibling of a co-employee resulting from a co-employee injury;
      • Bodily injury or personal injury arising out of providing or failing to provide professional health care services; or
      • Property damage to property owned, occupied, used by, or in the care, custody, or control of the named insured, any employee, or volunteer.
  2. Real Estate Managers:

    • Any person (other than an employee or volunteer) or organization acting as a real estate manager for the named insured.
  3. Temporary Custodians and Legal Representatives:

    • If the named insured dies, any person having proper temporary custody of the deceased insured's property (solely with respect to liability arising out of maintenance/use of that property) until a legal representative is appointed.
    • The legal representative of the deceased named insured (with respect to duties as such).
  4. Newly Acquired or Formed Organizations:

    • Any organization (other than a partnership, joint venture, or LLC) newly acquired or formed by the named insured, over which the named insured maintains majority ownership (> 50%), qualifies as a Named Insured for up to 90 days (or until the end of the policy period, whichever is earlier).
    • Limitation: Coverage does not apply to bodily injury, property damage, or personal/advertising injury that occurred prior to the acquisition or formation.

4. Mobile Equipment vs. Auto: Claims Coordination

A frequent source of coverage disputes and exam questions is the contractual boundary between "Mobile Equipment" (covered under CGL) and "Autos" (covered under Commercial Auto / BAP).

  • "Mobile Equipment": Land vehicles (including attached machinery/apparatus) meeting any of the following criteria:
    1. Bulldozers, farm machinery, forklifts, and other vehicles designed for use principally off public roads;
    2. Vehicles maintained for use solely on or next to premises owned or rented by the named insured;
    3. Vehicles that travel on crawler treads;
    4. Vehicles maintained primarily to provide mobility to permanently mounted power cranes, shovels, loaders, diggers, drills, or road construction/resurfacing equipment.

5. Practical Claims Adjuster Case Scenarios

Scenario A: General Aggregate Exhaustion Analysis

Case File: High Point Furniture holds a CGL policy with a $1,000,000 Each Occurrence Limit and a $2,000,000 General Aggregate Limit. During the policy year, High Point incurs three separate premises liability claims: Claim 1 settles for $800,000; Claim 2 settles for $900,000; Claim 3 goes to trial and results in a $600,000 judgment against High Point.

Adjuster Analysis:

  1. Claim 1: Insurer pays $800,000 (Remaining General Aggregate = $1,200,000).
  2. Claim 2: Insurer pays $900,000 (Remaining General Aggregate = $300,000).
  3. Claim 3: The judgment is $600,000, but only $300,000 remains in the General Aggregate. The insurer pays $300,000, completely exhausting the General Aggregate Limit. High Point is personally responsible for the remaining $300,000 excess balance, and the insurer's duty to defend future claims terminates for that policy year.

Scenario B: Fellow Employee Injury Exclusion

Case File: While operating a forklift inside an insured distribution warehouse, Employee Bob accidentally strikes co-worker Dave, breaking Dave's leg. Dave files a personal injury tort lawsuit directly against Bob.

Adjuster Analysis: While Bob is an employee acting within the scope of his duties, Section II contains the Fellow Employee Exclusion. Bob does not qualify as an insured for bodily injury caused to a co-worker in the course of employment. The CGL insurer will deny defense and coverage to Bob; Dave's exclusive remedy against the employer/co-worker is through the North Carolina Workers' Compensation Act.

Scenario C: Mobile Equipment in Transit vs. Jobsite Operation

Case File: A grading contractor uses a flatbed semi-truck to haul a heavy excavator to a road construction site. While traveling on a state highway, a securing chain breaks, and the excavator slides off the flatbed, crushing a passenger car. Upon reaching the site with another excavator, the operator swings the boom and strikes a utility pole, knocking out power to nearby businesses.

Adjuster Analysis:

  • Highway Crash: The excavator was in transit on an auto. The resulting liability is excluded under CGL and covered exclusively under the contractor's Business Auto Policy (BAP).
  • Jobsite Utility Strike: The excavator was operating as mobile equipment on the work site. The utility strike is covered under CGL Coverage A (Property Damage).
