Commercial Umbrella and Excess Liability Insurance

Commercial umbrella insurance and excess liability insurance both add limit above the liability policies a business already carries, and they are not the same instrument. An excess policy is normally written to follow the form of the policy beneath it. An umbrella is a policy in its own right, and depending on how that form is written, it may reach some claims the underlying policy does not. Which one a business needs is decided by the wording, the schedule of underlying insurance and the contracts it signs, not by the label on the quote.

Definitions appear in the general liability glossary and the commercial auto glossary.

What commercial umbrella insurance is

A commercial umbrella is a liability policy that sits above scheduled underlying policies and pays covered damages after the underlying limit is exhausted. It is bought for one of two reasons, usually both: a contract demands a total liability limit the primary policies cannot reach, or the business carries a severity exposure where a single verdict could exceed the primary limit and reach the balance sheet.

The feature that causes the most confusion is that some umbrella forms also respond to certain claims falling outside the underlying policy. Where that applies, the umbrella pays after a self-insured retention rather than after an underlying limit, because there is no underlying limit to exhaust. Whether a given umbrella does this at all, and for which claims, is a function of that specific form and its exclusions. It is not a characteristic every umbrella shares, and it should never be inferred from the word "umbrella" on a proposal.

What excess liability insurance is

An excess liability policy adds limit above a scheduled underlying policy and, in the common case, is written on a follow-form basis. Follow form means the excess policy adopts the terms, conditions and exclusions of the policy it sits over, so what the underlying covers is what the excess covers, at a higher limit.

Two qualifications matter. Follow form describes how a policy is drafted; it is not a guarantee attached to the word "excess." Many excess forms follow the underlying subject to their own exclusions and conditions, so the excess layer can be narrower than the policy beneath it in specific respects. And an excess policy that genuinely follows form inherits every exclusion in the underlying policy: if the primary excludes an exposure, buying excess limit over it does not create coverage for that exposure.

Umbrella versus excess liability

The two are frequently used interchangeably in conversation and on certificates, and frequently are not interchangeable in the policy wording. The table sets out the general distinction. The controlling document is always the form as issued.

How the layer attaches

An excess layer does not float above a program generally. It attaches to named policies at named limits, and that mechanism is where most coverage failures originate.

The schedule of underlying insurance

Every umbrella and excess policy carries a schedule listing the policies beneath it and the limits those policies must carry. A policy that is not on the schedule is not underlying, and the layer above generally does not sit over it. This is the most common reason an umbrella fails to respond the way the buyer expected.

Required underlying limits and the attachment point

The attachment point is the amount of underlying limit that must be exhausted before the excess layer begins to pay, and it is set by the required underlying limits stated in the schedule. If the schedule requires $1,000,000 of general liability and the general liability policy is actually written at $500,000, that gap generally belongs to the insured.

Maintenance of underlying insurance

These policies carry a condition requiring the insured to maintain the scheduled underlying insurance in full effect. Where underlying coverage is reduced, cancelled or written below the scheduled limit, umbrella and excess forms commonly respond as though the required underlying insurance were still in place, so the shortfall is not transferred to the excess carrier. Renewing a primary policy at a different limit without telling the excess carrier creates this gap by accident.

Aggregate erosion

Underlying aggregate limits erode as claims are paid during the policy period. Many umbrella forms provide that once an underlying aggregate has been exhausted by payment of covered claims, the umbrella continues in force for subsequent covered claims on the terms stated in that form. That behaviour belongs to the specific wording, and a business with frequency as well as severity exposure should confirm it rather than assume it.

Which policies the layer actually sits over

A commercial umbrella is normally scheduled over the general liability policy, the commercial auto liability policy and the employers liability section of the workers compensation policy. Those three are the conventional underlying package.

• General liability. The foundation layer, and the policy most often modified by contract requirements. Where a contract demands a total limit the general liability policy alone cannot reach, the umbrella is normally how the requirement is met. See general liability insurance.
• Commercial auto liability. Auto liability is the exposure most likely to produce a verdict above a primary limit, which is why fleet operations drive umbrella limit decisions more than almost anything else. The auto policy has to appear on the schedule of underlying insurance at the required limit. See commercial auto insurance.
• Employers liability. The umbrella sits over the employers liability part of the workers compensation policy, which responds to employee injury suits brought outside the workers compensation benefit system. It does not sit over statutory workers compensation benefits. See workers compensation insurance.

What is generally not included

Professional liability, cyber liability, directors and officers liability, employment practices liability, pollution liability and similar specialty policies are generally not covered by a commercial umbrella. They are typically excluded, and they are typically not scheduled as underlying.

The reason is structural. Most specialty policies are claims made, with a retroactive date, while general liability and auto liability are occurrence based. An umbrella drafted to sit over occurrence based policies cannot cleanly extend over a claims made professional liability policy without wording built for that purpose. Where a business needs higher limits on a specialty line, the answer is normally a dedicated excess layer over that specific policy rather than the commercial umbrella.

This matters commercially because contracts increasingly require a total liability limit inclusive of umbrella alongside a separate professional liability or cyber requirement. Reading the umbrella as satisfying both is a common and expensive misreading. See cyber liability insurance and professional services insurance.

Umbrella limit is not the same as a higher primary limit

Buying $1,000,000 of umbrella over a $1,000,000 general liability policy is not equivalent to buying a $2,000,000 general liability policy, and the differences run in both directions.

• The umbrella sits over auto liability and employers liability as well, so one layer raises the total available limit across several policies rather than one.
• Underlying aggregates and umbrella aggregates are separate limits. How they interact is set by the umbrella form.
• Defense costs are handled differently. Under most primary general liability policies, defense is provided in addition to the limit. Excess and umbrella forms vary: some provide defense in addition to the limit when they are the responding layer, some include defense within the limit, and most defer to the underlying insurer's duty to defend while underlying limits remain available. This is a wording question with real financial consequences on a long-running suit.
• Additional insured status does not automatically follow upward. Whether a party that is an additional insured on the general liability policy is also an insured under the umbrella depends on the umbrella's own definition of insured. Where a contract requires additional insured status at a stated total limit, this needs to be confirmed rather than assumed.

How the limit gets decided

No limit is correct for every business of a given size, and any broker who supplies one without reading the contracts is guessing. In practice the number comes from four inputs.

1. Contract requirements

For most businesses this is the binding constraint. Construction contracts, leases, master service agreements and vendor agreements state a required limit, frequently allowing it to be met with a combination of primary and umbrella limits. The number in the contract is the floor, not the analysis. Send the insurance requirements exhibit before signing.

2. Severity exposure

The question is not what a typical claim costs but what the worst credible claim costs. A single serious injury claim, particularly one involving a vehicle, can produce a demand well above a standard primary limit. Businesses that put employees on the road, invite the public onto their premises, or perform work that can injure someone after completion carry severity exposure whether or not they have ever had a large claim.

3. Balance sheet and ownership structure

The layer exists to keep a liability event from reaching assets. A business with significant retained earnings, owned real property or an ownership group with personal exposure is protecting more than a business operating on thin margins with financed equipment.

4. Operating profile

Certain profiles reliably drive the decision.

• Construction and contracting. Contract-required limits dominate, and requirements escalate with project size and with the general contractor above you. Completed operations exposure means the requirement outlives the job. See contractors and construction insurance.
• Fleet operations. Auto liability severity, driver turnover and miles driven make umbrella limits a live question for any business with vehicles, largely independent of revenue.
• Manufacturing. Products liability and completed operations exposure follow the product into markets and uses the manufacturer does not control, and customer contracts frequently specify limits. See manufacturing insurance.
• Property management and real estate. Premises liability across a portfolio, habitability and security-related claims, and management agreements that require specific limits per location. See property management insurance.
• Professional services firms. Client contracts often require general liability, auto and umbrella limits alongside a separate professional liability requirement. The umbrella satisfies the first set and generally not the second.

Common mistakes

• Assuming the umbrella sits over everything. It sits over what is scheduled. Professional liability, cyber, directors and officers and employment practices policies generally are not.
• Letting the underlying limit drift below the schedule. A primary policy renewed at a lower limit creates a gap the insured retains.
• Treating excess and umbrella as the same product because the certificate does. A certificate does not tell you which form is in force or what its exclusions say.
• Buying excess limit over an exposure the primary excludes. Follow form inherits exclusions. The limit is higher, the coverage is not broader.
• Sizing the limit to the last contract signed rather than the largest one expected. The shortfall is discovered at certificate time, when there is no time left to restructure the program.
• Assuming additional insured status carries up to the umbrella. It depends on the umbrella's definition of insured.
• Ignoring the self-insured retention. Where an umbrella responds to a claim with no underlying insurance, the retention is the insured's money, and on some forms it is substantial.

Questions to ask your broker before the layer is placed

• Is this an umbrella form or a follow-form excess form, and which specific form is being quoted?
• Which policies appear on the schedule of underlying insurance, and at what required limits?
• Do the limits on my actual primary policies match those required underlying limits exactly?
• Does this form respond to any exposure the underlying policies do not cover, and if so, what is the self-insured retention?
• Are defense costs inside or outside the limit when this layer is the responding layer?
• Does the umbrella extend to the additional insureds my contracts require, at the total limit those contracts specify?
• What happens to this layer when an underlying aggregate is exhausted part way through the policy period?
• Which of my exposures does this layer specifically not cover, and what would it take to place excess limits over those?

What underwriters generally need

An excess submission is largely a question about the underlying program and the operations behind it. Expect to provide current declarations pages and endorsement schedules for every policy that will be scheduled as underlying, currently valued loss runs covering several years, and a description of operations including work performed for others.

Beyond that, underwriters want detail on whatever drives severity: vehicle schedules, driver lists and the motor vehicle record process for fleet exposure; trade, work at height and subcontractor insurance requirements actually enforced for construction; products, end use and any recall or field failure history for manufacturing; the schedule of locations, occupancy and the maintenance and security program for real estate. Contracts carrying unusual limit or additional insured requirements should go in with the submission rather than surface afterwards.

Commercial umbrella and excess liability FAQ

What is commercial umbrella insurance?

A liability policy that sits above scheduled underlying policies, normally general liability, commercial auto liability and employers liability, and pays covered damages once the underlying limit is exhausted. Some umbrella forms also respond to certain claims outside the underlying policies, subject to a self-insured retention, but that varies by form and should not be assumed.

Is excess liability the same as umbrella insurance?

No, although the terms are used interchangeably in everyday conversation. An excess policy is commonly written to follow the form of the policy beneath it, so it adds limit on the same terms. An umbrella is a policy with its own insuring agreement, conditions and exclusions, which can differ from the underlying. The distinction is settled by reading the form, not by the label.

What does a commercial umbrella policy cover?

It covers damages the scheduled underlying policies cover, above their limits. In practice that means bodily injury and property damage claims under general liability, liability arising from vehicles under commercial auto, and employee injury suits under employers liability. It generally does not cover professional liability, cyber, directors and officers or employment practices claims.

How does commercial umbrella insurance work when a claim exceeds the primary limit?

The underlying insurer handles and pays the claim up to its limit. Once that limit is exhausted by payment, the umbrella responds for covered damages above it, up to the umbrella limit. If the underlying policy was written below the limit required in the schedule of underlying insurance, the difference is generally the insured's responsibility.

How much commercial umbrella insurance does a business need?

Program limits of $1,000,000, $2,000,000, $5,000,000 and $10,000,000 or more are all common, and none of them is universally appropriate. The limit is driven by the highest limit the contracts you sign require, the worst credible claim your operations could produce, and the assets a liability judgment could reach. A business with a fleet and construction contracts and a business with an office and no vehicles can be the same size and need very different limits.

Does a commercial umbrella cover professional liability or cyber claims?

Generally no. Those exposures are normally excluded from a commercial umbrella and are not scheduled as underlying, in part because they are usually written on a claims made basis while general liability and auto liability are occurrence based. Higher limits on those lines normally require a dedicated excess layer over the specific policy.

What is follow form excess coverage?

An excess policy drafted to adopt the terms, conditions and exclusions of the underlying policy, so that coverage above the underlying limit matches coverage below it. In practice many excess forms follow the underlying subject to their own exclusions and conditions, so a follow-form policy is not automatically identical to the underlying in every respect.

What is an attachment point?

The amount of underlying limit that must be exhausted before the excess or umbrella layer begins to pay. It is fixed by the required underlying limits stated in the schedule of underlying insurance, which is why those limits and the limits actually carried need to match.

Why would a contract require umbrella coverage?

Because the party requiring it wants a total available limit larger than a primary liability policy normally carries, and frequently wants that limit available to them as an additional insured. Construction contracts, commercial leases, master service agreements and vendor agreements are the usual sources. The requirement is set by the contract rather than by any state law.

Review the layer before the contract, not after the claim

Umbrella problems surface at one of two moments: when a certificate is requested for a contract the program cannot satisfy, or when a claim exceeds a primary limit and the schedule of underlying insurance does not say what everyone assumed it said. Both are avoidable by reading the forms in advance.
