Additional Insured Endorsement


Additional Insured Endorsements - After the Work is Done

Michelle is a new account manager for The O’Leary Agency. She handled very few construction accounts in her previous position with another insurance agency, but that’s changing. It has become apparent to Michelle that, in working for The O’Leary Agency, she has to learn a great deal about insurance for construction accounts, including more about additional insured coverage.
This became painfully obvious to Michelle when the certificate of insurance she issued last week for a subcontractor customer was rejected by the general contractor. Specifically, the general contractor’s legal counsel pointedly told Michelle that the “blanket” additional insured, or CG 20 38 Additional Insured-Owners, Lessees or Contractors – Automatic Status for Other Parties When Required in a Written Construction Agreement (this topic and other additional insured endorsements was addressed in the July 2014 edition of The Edge), “was wholly insufficient and entirely unacceptable in light of the insurance provisions of the construction contract.”

Additional Insured – Completed Operations

Feeling admonished, Michelle set out to understand what exactly was missing. Apparently, in the construction contract between the general contractor and subcontractor, the subcontractor is required to include the general contractor as an additional insured for completed operations coverage for a period of six years after the subcontractor’s work is finished. While the current “blanket” additional insured endorsement CG 20 38 does meet a portion of the insurance requirements – to protect the additional insured for certain bodily injury or property damage claims that take place during the project – the CG 20 38 specifically excludes any bodily injury or property damage that takes place after her customer’s work is finished.
At first, this notion puzzles Michelle. Why would the general contractor want to be an additional insured six years after her customer’s work is finished? Michelle’s supervisor, Paul, uses an example that shows the rationale behind completed operations coverage for an additional insured.
Example: A general contractor has been engaged by the owner to construct a small restaurant building in the downtown area. Much of the work, such as HVAC, electrical, plumbing, and site preparation, is completed by trade subcontractors hired by the general contractor. Eight months after the building has been completed by the general contractor and put to use as a restaurant by the building owner, a small fire breaks out in the mechanical room, injuring two of the restaurant’s servers. When it is determined that the fire was the result of sloppy electrical work, the general contractor is sued by the injured servers for bodily injury.
In this example, if the general contractor had been listed as an additional insured on the electrical subcontractor’s policy with only the CG 20 38, no coverage would have been provided to the general contractor as an additional insured. This is because the bodily injury to the servers took place months after the work that caused injury was finished – and the CG 20 38 excludes any bodily injury caused by work that has been completed. Similarly, Paul explains, the additional insured endorsements CG 20 33, CG 20 10 and CG 20 26 also exclude coverage for the additional insured for any bodily injury caused by finished work.
Additional Insured – Completed Operations CG 20 37. On the other hand, if the electrical subcontractor had listed the general contractor as an additional insured on its policy using CG 20 37 – Additional Insured – Owners, Lessees or Contractors – Completed Operations, the general contractor would have been covered as an additional insured by the electrical contractor’s CGL policy, provided the electrical contractor’s acts or omissions, at least in part, caused the bodily injury to the servers.
It is commonplace for general contractors to not only require additional insured coverage on the CGL policies of all subcontractors, but to also require the additional insured coverage to apply bodily injury or property damage that takes place both during and after the project is finished. The CG 20 37 – Additional Insured – Owners, Lessees or Contractors – Completed Operations has been specifically written to provide coverage to the additional insured for certain bodily injury or property damage claims  that occur after the project is finished.
Armed with this knowledge, Michelle requests from her customer’s insurer not only the CG 20 38 but also the CG 20 37 and lists the general contractor as the additional insured. After being granted the CG 20 37 by her customer’s insurer, Michelle re-issues the certificate of insurance, now showing the CG 20 37 protecting the general contractor as an additional insured for completed operations.

The Six-Year Requirement

Michelle is still a bit anxious about whether the legal counsel for the general contractor will accept the revised certificate of insurance. She is concerned that the insurance requirement in the contract also requires the inclusion of the general contractor as an additional insured for completed operations coverage for a period of six years after her customer’s work is completed; Michelle knows the CGL policy on which the general contractor is an additional insured is only for a one-year term.
After some confusion, the legal counsel of the general contractor finally clarifies what is being required – Michelle’s customer is to continue to purchase a CGL policy with a one-year policy term for the next six years, with all six policies including the general contractor as an additional insured for completed operations using CG 20 37.

Extended Completed Operations Coverage

The O’Leary Agency has just assigned Michelle another customer – a large contractor preparing to act as the prime contractor on the construction of a $75 million regional high school project. While this general contractor has its own liability insurance program (sometimes called its “practice insurance program”), they have also decided to purchase a separate project specific liability insurance program. In other words, Michelle’s general contracting customer has purchased a separate CGL with a policy term of 24 months (the expected duration of the project) including excess layers of coverage, all of which applies only to the regional high school building project.
One of the regional school system’s insurance requirements as the school’s owner is that the general contractor must purchase completed operations coverage for a period of 10 years beginning after the project is completed. The general contractor must also include the regional school system as an additional insured for all 10 years of completed operations coverage.
In response to the owner’s requirement, the general contractor asks Michelle to add extended completed operations coverage to their project-specific CGL policy to comply with the owner’s request. Not at all sure what extended completed operations coverage is and how it differs from the usual completed operations coverage, Michelle conducts some research.
What Michelle learns is less complicated then she imagined – as the project-specific CGL policy will expire in 24 months, the extended completed operations coverage is a non-standard endorsement that states the general contractor’s completed operations coverage for the regional high school project will continue beyond the policy expiration and continue for 10 years after substantial completion of the high school. In other words, if a completed operations claim happened at the regional high school five years after the project is complete, the general contractor’s project-specific CGL policy would have terminated – but the extended completed operations coverage would still be in effect and thus would apply to certain types of bodily injury or property damage that takes place up to 10 years after the school project is completed.
Extended Completed Operations Coverage and Additional Insured. Adding the regional high school as an additional insured for completed operations to the general contractor’s project-specific policy is also straightforward – through use of the CG 20 37 Additional Insured – Owners, Lessees or Contractors – Completed Operations and by listing the regional school as the additional insured on this endorsement, coverage will apply to the additional insured school for the entire period of the extended completed operations endorsement found in the general contractor’s CGL policy.


Completed operations coverage for additional insureds is often overlooked or may not be available. Some insurers have their own proprietary additional insured endorsements, which may or may not include completed operations coverage for the additional insured.
The Insurance Services Office (ISO) additional insured endorsements generally exclude products-completed operations coverage; so if completed operations coverage is required for the additional insured, the CG 20 37 – Additional Insured – Owners, Lessees or Contractors – Completed Operations is often needed.
In some instances, the liability coverage provided by a project-specific policy that includes extended completed operations may be a good option – and one that can be further amended to provide coverage for the additional insured during the entire period of the extended completed operations coverage by using CG 20 37 or a similar endorsement.

From Seed to Sale: The Top 5 Issues Impacting the Cannabis Insurance Industry


​Over the last few years, the legal cannabis industry has seen rapid growth and had a significant impact on the U.S. economy. With states continuing to legalize its use, insurance needs for cannabis-related businesses are becoming a popular topic of discussion. This article examines the evolving cannabis industry by exploring five key issues impacting coverage.

Four Key Additional Insured Endorsements for Contractors

Construction contract negotiations, which determine the kind and amount of insurance required for a construction project, can be time-consuming, complicated and frustrating. Project owners require contractors on a project to name the project owner as an additional insured on the contractor’s casualty insurance program. It's important that both project owners and contractors understand the coverage provided by these additional insured endorsements. This article discusses four common ISO additional insured endorsements related to commercial general liability policies purchased by contractors, including their limitations, conditions and exclusions.

Claims Reporting: Better Late than Never?

A common complication during the claim process is the late reporting of claims. In some cases, a late claim can put the agent or broker's own E&O policy in jeopardy. There are many reasons for missing a reporting deadline; however, in most cases, they will not matter to the insurer or the courts. This article discusses typical claim reporting requirements, common causes of late reporting, and recommendations to mitigate the risk of late notice claim denials.

Understanding Property Theories of Recovery and Ensuing Loss Clauses

​The theories of recovery, as well as the ensuing loss provisions, contained in property insurance policies are often complex and, at times, seemingly in conflict. Although a policy may not directly address these theories, their application by courts plays a significant role in the coverage determination process after the claim. It is essential that brokers understand the primary theories of recovery – Efficient Proximate Cause, the Concurrent Causation Doctrine, and the Anti-Concurrent Causation Doctrine – in order to navigate the challenging post-claim process and effectively serve their clients.

Ordinance or Law Insurance Coverage

Ordinance or Law insurance coverage provides limited protection for costs associated with repairing, rebuilding, or constructing a structure when physical damage to the structure by a covered cause of loss triggers an ordinance or law. Compliance with ordinances and laws after a loss can add 50% or more to the cost of a claim. This article will help you educate your insureds on exclusions and limitations and help them take a proactive approach to their insurance program.

Employment Practices Liability in the Age of #MeToo
