Limits above the primary policies

Umbrella and Excess Liability Insurance California

844-97-USAVE

A single serious claim can pass a standard liability limit faster than most businesses expect, and the gap is not usually discovered until the primary limit is exhausted. An umbrella is generally the cheapest height a commercial program can buy, which is why contracts so often ask for one.

Exposure-Dependent Coverages

Business Owners Policy / Commercial PackageLiability and property components evaluated together

What it is

A Business Owners Policy commonly combines liability and property coverages for eligible businesses. A Commercial Package Policy may combine multiple commercial coverage parts depending on the account and carrier.

Why businesses like yours commonly carry it

Businesses with premises, contents, inventory or other property exposures may ask GIB to evaluate whether liability and property components can be packaged where appropriate.

Possible coverage gap

Eligibility, included coverages and package structure vary by carrier. Commercial Property may also be written separately rather than as part of a package.

Umbrella / Excess LiabilityAdditional limits above scheduled liability policies

What it is

Umbrella or Excess Liability may provide additional limits above identified underlying liability policies, subject to its own terms and exclusions.

Why businesses like yours commonly carry it

Businesses with larger contracts, vehicles, public exposure or higher severity potential commonly consider additional limits.

Possible coverage gap

An umbrella does not automatically broaden every exclusion or sit over every policy unless the issued terms say it does.

How the layers actually stack

An umbrella or excess policy sits above named underlying policies — commonly general liability, commercial auto and employers liability — and responds once those limits are exhausted by covered claims.

Read more

It does not sit above everything by default. The schedule of underlying insurance is the list of what it actually sits on, and a policy left off that schedule has nothing above it.

This is why an umbrella is quoted against a specific program rather than in isolation, and why changing a primary carrier mid-term matters: if the underlying limits drop below what the umbrella requires, there is a gap between the layers that the business pays for itself.

Responds above the limits of specifically scheduled underlying policies
A policy not on the schedule has no umbrella above it
Underlying limits must be maintained at the required amounts
Changing a primary carrier mid-term can open a gap between layers

Umbrella and excess are not quite the same thing

The words are used interchangeably in conversation, and the forms are not identical.

Read more

A true umbrella can be broader than the policy beneath it and may drop down to respond where the underlying policy does not cover a claim at all, usually subject to a self-insured retention. A follow-form excess policy simply mirrors the underlying terms at a higher limit and is no broader than what it sits on.

Neither is better in the abstract. What matters is which one you were quoted, because the difference only shows itself on the claim where the underlying policy does not respond — and that is the claim a business most wants height for.

Follow-form excess mirrors the underlying terms at a higher limit
A self-insured retention applies where an umbrella drops down

What a contract is really asking for

Leases, vendor agreements and venue contracts commonly specify a total limit and leave it to the business to decide how to reach it.

Read more

Reaching $5 million with a $1 million primary and a $4 million umbrella is usually far cheaper than buying a $5 million primary, and generally satisfies the requirement.

Read the clause rather than the number. Some contracts require the umbrella to sit over specific policies, to be primary and non-contributory, or to include the other party as an additional insured on the excess layer as well as the primary. Those are separate requests and are not automatic.

Contracts usually state a total limit and leave you to reach it
A primary plus an umbrella is normally cheaper than a high primary alone
Check whether the clause also asks for primary and non-contributory wording

How much height is enough

There is no formula, and anyone offering one is selling something.

The useful questions are what a serious claim in your operation could plausibly cost, what the business has to lose, and what your contracts already oblige you to carry. A business with vehicles on the road, with the public on its premises, or with a large payroll tends to need more height than its revenue alone would suggest.

Cost usually scales gently with the first few million and then more steeply, so the practical exercise is to price several layers and look at what each one costs rather than guessing at a number first. Nothing here is a guarantee of what any policy will pay; what a policy covers is set by its own terms.

What your contracts already oblige you to carry
Cost scales gently over the first few million, then more steeply

The underlying schedule, and why it decides everything

An umbrella does not float above a business in general.

Read more

It sits over a named list of underlying policies at stated minimum limits, and that list is printed on the policy. If general liability, commercial auto and employers liability are scheduled, those are the three places it reaches. A policy not on the schedule is usually not covered by the umbrella at all, however serious the claim.

Two things commonly break the arrangement, and both are administrative rather than dramatic. The first is changing an underlying carrier mid-term without telling the umbrella carrier, which can leave the schedule describing a policy that no longer exists. The second is letting an underlying limit fall below the required minimum: if the umbrella requires one million underneath and the renewal came back at five hundred thousand, the difference is generally the insured’s to pay before the umbrella engages. Neither is discovered at a convenient moment.

The schedule names which policies the umbrella sits over
Required underlying limits are a condition, not a suggestion
Changing an underlying carrier mid-term should be reported
Professional liability and cyber are frequently not scheduled underliers

Before the transfer can work

Having the right endorsement is only half of it

A general illustration of common practice, not a description of any particular contract, carrier or policy.

What generally has to be in place

A written contract, in place before the loss. Blanket additional insured forms typically operate only where an agreement already requires the status — the wording is usually some form of "as required by written contract". An agreement signed after something has happened generally does not reach back, and a certificate on its own creates no obligation at all.
The endorsement actually attached to the policy. A certificate of insurance evidences that a policy existed on the day it was issued. It is not proof that any particular endorsement sits on that policy, which is why a requirement is commonly checked against the endorsement rather than the certificate.
The same named insured on both documents. The entity on the subcontract and the entity on the policy need to match. A DBA, a single-purpose entity for one project, or a renamed business are all ordinary reasons paperwork is rejected late, when there is least time to fix it.
Terms the policy itself allows. Availability differs by carrier, by line of insurance and by account. Whatever is granted is whatever the issued policy and the endorsements attached to it say — not what the contract asked for, and not what the certificate lists.

Two endorsements commonly named alongside additional insured status

Two endorsements commonly requested alongside additional insured status, the form number usually associated with each, and what each one generally does
EndorsementForm commonly usedWhat it generally does

Waiver of subrogationCG 24 04Gives up the insurer’s right to recover from the upstream party after paying a claim. Frequently named alongside additional insured status rather than instead of it.

What a serious California claim actually costs

The reason excess limits exist is that the gap between a routine claim and a severe one is not a matter of degree.

Read more

A disputed slip-and-fall settles in a range most businesses could survive. A collision involving a commercial vehicle and serious injuries, a fire that spreads from one tenancy to the rest of a building, or an incident involving several claimants at one event can run past a one-million primary limit on the medical costs alone, before anything else is argued.

California adds two pressures to that arithmetic. Medical costs and wage levels are high, so the same injury is worth more here than in most states. And defense costs in a contested matter are substantial on their own — on many primary forms defense sits outside the limit, but once the primary is exhausted that protection goes with it. An umbrella is usually bought for the tail of outcomes rather than the middle, which is exactly why it is cheap relative to the primary layer underneath it.

Severity, not frequency, is what excess limits are bought for
Serious injury claims can pass a primary limit on medical costs alone
California wage and medical levels raise the value of the same injury
Defense protection on the primary ends when the primary is exhausted

Umbrella requirements in California contracts and leases

A great many umbrellas are bought because a document asked for one, and in California the document usually comes from a landlord, a public agency or a large customer.

Read more

Commercial leases in Los Angeles, Orange County, San Diego and the Bay Area routinely specify combined limits that cannot be reached with a primary policy alone, and municipal permits, large client agreements, venue contracts and lender requirements do the same. The request is usually expressed as a total figure rather than as a structure, which is why a five-million requirement is normally met with a one-million primary and a four-million umbrella rather than a single large policy.

Read the wording rather than just the number. Some contracts require the umbrella to be at least as broad as the underlying policy, some require the additional insured status to carry up through the umbrella, and some name coverages that an umbrella does not usually sit over at all. Agreeing to a limit is easy; agreeing to a structure your policies do not have is the expensive version.

Requirements are usually stated as a total, met by primary plus umbrella
Some contracts require additional insured status to follow up the tower
"At least as broad as the underlying" is a real and checkable requirement
Confirm the structure, not only the number, before signing

Buying the layer: limits, retentions and the cost curve

Excess layers get cheaper per million as they go up, because each additional layer is less likely to be reached.

Read more

The first million of umbrella above a primary usually costs more than the fifth, which means the question is rarely whether to buy an umbrella at all and more often how high to go once one is in place. For most operations the honest comparison is the cost of the next layer against the size of the worst plausible claim, not against last year’s premium.

A self-insured retention is the other variable. Where there is no underlying policy for a particular exposure, an umbrella may still respond above a retention the insured pays first, and that retention can be substantial. It is worth knowing whether your policy carries one and what it applies to, because a retention discovered during a claim is functionally a deductible nobody budgeted for.

Each successive layer generally costs less per million than the one below
The useful comparison is the layer cost against the worst plausible claim
A self-insured retention is paid by the insured before the policy responds
Retentions most often appear where no underlying policy exists

Frequently asked questions

15 questions — start typing to filter

What is the difference between umbrella and excess liability?

A true umbrella can be broader than the policy beneath it and may drop down to respond where the underlying policy does not cover a claim, usually subject to a self-insured retention. A follow-form excess policy mirrors the underlying terms at a higher limit and is no broader than what it sits on. The difference only shows itself on the claim where the underlying policy does not respond.

Does an umbrella sit over all of my policies?

Only over the ones named in its schedule of underlying insurance. That commonly means general liability, commercial auto and employers liability. Professional liability, cyber and liquor liability are frequently excluded unless specifically scheduled, so a business relying on an umbrella to back those should confirm it rather than assume it.

How much umbrella do I need?

Your contracts usually set a floor, and beyond that it is a question of what a serious claim could plausibly cost relative to what the business has to lose. Cost tends to scale gently over the first few million, so pricing several layers and comparing is more useful than settling on a number in advance.

Is an umbrella cheaper than raising my primary limit?

Usually, and often substantially. Reaching a $5 million requirement with a $1 million primary and a $4 million umbrella is commonly far less expensive than buying a $5 million primary, and generally satisfies a contract asking for a total limit.

What happens if I change my general liability carrier mid-term?

The umbrella needs to know. It sits above specific scheduled policies at specific limits, and if the new primary carries lower limits or different terms, a gap can open between the layers that the business pays for itself. Tell your broker before the change rather than after it.

Does an umbrella cover employment claims or professional mistakes?

Generally not unless those policies are scheduled underneath it, and often not even then. Employment practices and professional liability are commonly excluded from umbrella forms, which is why a business carrying real exposure in either usually buys height on those policies directly.

What is a self-insured retention?

It is the amount the insured pays before a true umbrella responds to a claim the underlying policy does not cover at all. It is not the same as a deductible on the primary, and it applies only in the drop-down situation rather than to every claim.

Can a small business buy an umbrella?

Yes, and many do, often because a lease or a customer contract requires it. Eligibility depends on the underlying program being acceptable to the umbrella carrier, which is another reason the two are quoted together rather than separately.

What is drop-down coverage?

It describes an umbrella responding where the underlying policy does not, typically because the underlying aggregate has been exhausted by earlier claims. Forms differ considerably on whether and how they drop down, and some require a retention to be paid first. It is one of the clearer differences between two umbrella quotes at the same limit, and it is worth asking about directly.

Does an umbrella increase my defense cost protection?

Generally the umbrella provides defense for claims it covers once the underlying limits are exhausted, but the arrangement varies by form. The point worth understanding is that defense protection on the primary policy ends when the primary limit is gone, so on a severe claim the umbrella is what stands behind both the damages and the continuing cost of defending.

Can I buy excess over only one policy?

Yes. A true excess policy can sit over a single underlying line — commercial auto only, for example — whereas an umbrella typically sits over several. Businesses with one dominant exposure sometimes find a single-line excess policy a better fit, and a contract naming a limit for one specific coverage can sometimes be satisfied that way.

Why does my umbrella carrier care who writes my auto policy?

Because it is relying on that policy to absorb everything below its own attachment point. An umbrella carrier is effectively underwriting the quality and the limits of the layer beneath it, so changing an underlying carrier, limit or form is a change to the umbrella’s own risk. Telling them promptly is not a formality; the schedule is a condition of the policy.

Does an umbrella cover punitive damages?

Often not, and where it might, the position varies by form and by the law applied to the claim. Insurability of punitive damages is a legal question rather than purely a policy one, and it differs between jurisdictions. If that exposure matters to your operation it is a question for counsel alongside the policy wording, not one to settle from a brochure.

How quickly can a claim reach a primary limit?

Faster than most businesses expect once serious injury is involved. Hospitalization, surgery, rehabilitation and lost earnings accumulate before liability is even settled, and a single claimant with a severe injury can approach a one-million limit on medical and wage loss alone. Multiple claimants from one event compress that further.

Is an umbrella cheaper than simply raising my primary limit?

Usually, and often by a wide margin, because the umbrella only engages after the primary is exhausted while a higher primary limit is exposed to every claim from the first dollar. Pricing both is still worth doing: on some risks a modest primary increase is the better buy, and the only way to know is to put the two quotes side by side.
