Definition:Completed operations
🏗️ Completed operations is an insurance concept referring to liability arising from work that a contractor, manufacturer, or service provider has finished and handed over, where the resulting product or project later causes bodily injury or property damage to a third party. In commercial general liability underwriting, completed operations represents a distinct hazard category — separate from premises and operations exposure — because the insured no longer has control over the work at the time the loss occurs. A plumbing contractor whose faulty installation causes a flood six months after project completion, for example, faces a completed operations claim rather than an operations-in-progress one.
🔧 Underwriters assess completed operations exposure by examining the nature of the insured's work, the duration over which latent defects might manifest, the quality-control procedures in place, and the insured's historical claims experience. The ISO CGL policy form includes completed operations within the "products-completed operations hazard" classification, and premium for this coverage is typically calculated using a separate rate applied to the insured's receipts or payroll. Some policy forms allow the coverage to be included or excluded, and the choice significantly affects the overall risk profile and price of the policy. Additional insured endorsements extending completed operations protection to project owners or general contractors are among the most commonly negotiated coverage provisions in construction insurance.
📐 The distinction between ongoing and completed operations is far more than academic — it drives reserving practices, reinsurance treaty structures, and statutes of repose analysis. Losses from completed operations often have long reporting tails, meaning claims may surface years after the policy period, which complicates IBNR estimation. For insurers writing construction-related risks, understanding and properly pricing completed operations exposure is essential to avoiding adverse reserve development and maintaining underwriting profitability over time.
