Umbrella: when $1M/$2M stops being enough

The honest answer is that $1M/$2M runs out two ways, and most contractors only plan for one of them. The first is the bad day: one occurrence bigger than a million dollars. The second is the slow one: a year of additional insured tenders that eat the $2M aggregate a few hundred thousand at a time, until the policy you’re showing on certificates in October is thinner than the certificate says. An umbrella is the answer to both, if it’s built right. Here’s how the limits actually get used up, what the umbrella does and inherits, and how to size it from the contract instead of from a guess.

The bad day

A Mack dump truck loaded with road base comes down College Avenue in Fort Collins on a freeze-thaw morning, the brakes fade, and it goes through a light. Two people hurt badly. The commercial auto pays its $1M combined single limit and the claim keeps going. Or a mid-size excavator on a utility trenching job in expansive clay undermines a neighbor’s foundation, and the repair plus the neighbor’s relocation plus the GC’s defense passes the GL’s occurrence limit before anyone has finished arguing about fault.

That’s the claim everyone pictures when they hear “umbrella.” Under most standard forms, the umbrella pays above the underlying policy’s limit, up to its own limit, and typically picks up defense costs above the underlying too. Simple, until you read what’s underneath.

The slow day

The second way is quieter and it’s the one GC work causes. Every time you name a GC as an additional insured with primary and non-contributory wording, a claim tied to your work draws from your occurrence limit and your general aggregate. The additional insured article explains why the GC wants that. The primary and non-contributory article explains why your carrier can’t ask theirs for help.

Three of those in one policy year, none catastrophic, and your $2M aggregate is a lot smaller than $2M. The certificate still says $2M. The GC’s coordinator on the fourth job doesn’t know about the first three. If the fourth claim is the big one, the aggregate is what’s left, not what’s printed.

An umbrella typically sits above the aggregate as well as the occurrence limit, so it responds when the underlying is exhausted by a series of claims, not just by one. A per-project aggregate endorsement on the GL is the other answer to the slow day: the $2M refreshes for each job instead of being shared. Some exhibits ask for it outright. Both are worth asking about.

Where the number comes from

Not a formula. A contract. Private GC exhibits commonly ask for a stated umbrella limit following form over GL, auto, and employer’s liability. Public work reads the same way with different numbers, and it’s worth seeing two Colorado examples side by side.

The CDOT figures are still being confirmed against the current permit form, so treat them as the shape of the ask rather than a settled number. The point holds either way: a $2M aggregate is a common floor a city or the state puts on a license or permit, and GC exhibits build up from there. If you sign one contract this year that asks for $5M, the umbrella has to be $5M on the day the certificate is due. The GC exhibit article covers the clause in context.

What the umbrella needs underneath

An umbrella is a policy on top of a schedule. The schedule is the list of underlying policies it sits over (GL, commercial auto, employer’s liability, sometimes pollution), with the minimum limits the umbrella carrier requires on each one. Two things break here.

The underlying doesn’t match the schedule. The schedule says auto at $1M CSL. The auto policy was renewed at a lower limit to save money. On the auto claim, the umbrella typically treats the gap between the real limit and the scheduled limit as yours. The commercial auto page is where most of these mismatches start.

Something is missing from the schedule. A plow truck on a personal policy. An employee’s pickup with no hired and non-owned coverage on the auto policy, which the HNOA article covers. A location or an entity the umbrella never heard of. The umbrella follows the schedule. What isn’t underneath isn’t on top.

What the umbrella inherits

People buy an umbrella hoping it fixes what’s wrong below. Under most standard forms it doesn’t. Two kinds of policy sell under the same word.

Follow-form excess adopts the underlying policy’s terms. A GL with an XCU exclusion means a trench collapse is excluded below, and excluded above. A pollution exclusion on the GL means a fuel spill is excluded on the umbrella too, which is why a separate pollution policy exists. The XCU article explains the exclusion that bites excavators hardest.

True umbrella can be broader than the underlying and can drop down over a self-insured retention to cover some claims the underlying doesn’t. That sounds better, and sometimes it is. In practice most contractor umbrellas are written close to follow-form, and the broadening is narrow. The policy language controls, and the words to read are the definition of “underlying insurance” and the exclusions section.

Either way: fix the primary first. A bigger umbrella over a bad GL is a bigger version of the same hole.

Additional insured and primary wording on the umbrella

The exhibit that asks for additional insured status and primary wording on the GL will often ask for both on the umbrella. Those are separate endorsements from a separate carrier, and the umbrella carrier decides what it will write. Some follow the underlying automatically. Some want a scheduled endorsement for each GC. Read the umbrella’s additional insured provision before the certificate says anything about it.

What to do before the next exhibit

Pull every contract you expect to sign in the next twelve months and find the highest umbrella number. That’s the target. Then read the umbrella’s underlying schedule against the auto and GL dec pages, line by line. Any mismatch is a gap the umbrella will find before a claim adjuster does. What we don’t control is the umbrella carrier’s minimum underlying limits, which vary by carrier and by trade. That’s a number to get with the quote, not after.

Where to go from here

If a contract on your desk asks for more than you carry, Get Insured starts with that exhibit, because the umbrella and the underlying limits have to be built to it together. If you have an umbrella and have never read the underlying schedule, a policy review puts the schedule next to the dec pages and marks the mismatches. Excavation contractors hauling into Denver and up the I-25 corridor to Fort Collins tend to hit the $5M ask sooner than they expect, and the dump truck page explains why the auto line is where it bites.
