What Is CG 20 10 Endorsement in Insurance?

Plain-language definition: 

The CG 20 10 endorsement is an additional insured endorsement that construction companies attach to their general liability insurance. It provides coverage to other parties, like project owners or general contractors, for any accidents or damage related to the construction work.

Common Questions About CG 20 10 Endorsement

What is the difference between CG 20 10 and CG 20 37? 

CG 20 10, depending on edition date, may only cover ongoing operations performed for the additional insured. If the work is complete and an accident later occurs, this form may not offer coverage. That’s where the CG 20 37 endorsement comes in, covering completed operations for the additional insured. 

Why is the CG 20 10 – 11/85 version preferred by potential additional insureds? 

The 11/85 version is unique because it extends coverage for your ongoing operations and for liability arising out of completed operations. This is beneficial for stakeholders like project owners in situations where a loss occurs due to the contractor’s work even after the project is done. 

What are some typical exclusions on the CG 20 10 endorsement? 

The CG 20 10 endorsement will not cover damage to the additional insured’s product, work performed by their own employees, or defects in the named insured’s work discovered before the project has been completed. 

How does the CG 20 10 endorsement limit the insurance carrier’s liability in case of a claim? 

The endorsement explicitly states that it does not increase the policy’s limits of insurance. This means that if a loss exceeds the named insured’s policy limit, any additional costs might not be covered by the insurer. 

CG 20 10 vs. CG 2037

The distinct difference between the CG 20 10 and CG 2037 forms lies in the coverage provided for ongoing operations and completed operations.

Real Claim Examples Involving CG 20 10 Endorsement

Scenario 1: A construction firm subcontracted part of a job on a multi-million dollar project. After project completion, a passerby was injured due to a defect in the work performed by the subcontractor. The project owner, an additional insured under the contractor’s policy via a CG 20 10 endorsement, was held liable. The insurer covered the claim under the policy. 

Scenario 2: During construction, a falling tool caused property damage to a nearby building. The building owner sued for compensation. The general contractor was listed as an additional insured under the subcontractor’s policy with a CG 20 10 endorsement, and the insurer defended and settled the claim. 

Scenario 3: In a property development project, a finished building collapsed due to structural flaws in the materials used by the contractor. The Developer, listed as additional insured on the CG 20 10 (11/85) endorsement, filed a claim. The insurer dismissed the claim, citing the finished work exclusion in the standard CG 20 10 endorsement. However, as the 11/85 edition covered completed operations, the decision was challenged, and the insurer eventually accepted the claim. 

Limitations and Common Mistakes

  • The CG 20 10 endorsement does not increase policy limits. The limit is shared among all insureds. 
  • Standard CG 20 10 endorsements do not automatically cover completed operations but older editions like the 11/85 do. 
  • The additional insured status is only granted when required by a written contract or agreement. 
  • The additional insured coverage is limited to the scope of work agreed upon with the named insured.
