Trading Premium for Retention: Northline Mechanical's Renewal Decision
Northline Mechanical is a 38-van HVAC and plumbing contractor with $31 million in revenue, split roughly 60/40 between service work and new-construction installations. At renewal the broker presents a combined general liability and commercial auto premium of $212,000, up from $178,000. The CFO wants relief and proposes raising the per-claim deductible from $5,000 to $25,000, which the carrier prices at a $46,000 saving, and adding a $2 million umbrella for $18,500.
Five-year loss runs show 22 auto physical damage claims averaging $3,800 - almost all backing and parking incidents in tight service lots - one auto liability claim at $4,100, two general liability slip-and-fall claims paid at $85,000 and $140,000, and one still-open completed-operations claim reserved at $300,000 arising from a rooftop unit installation. Working capital is $900,000. The company has no formal safety program, no telematics, and no driver training. Construction-side contracts require $1 million per occurrence, $2 million general aggregate, and a $2 million umbrella.
1. Using total cost of risk rather than premium alone, evaluate the deductible change and the umbrella purchase. What do you recommend, and what would change your answer?

Start with total cost of risk: premium plus retained losses plus uninsured losses plus administrative cost. The $46,000 saving is real, but it only pays for claims landing between $5,000 and $25,000. The 22 auto physical damage claims average $3,800, and an average tells you nothing about how many sit above $5,000 - request a claim-size distribution before signing.
Run the sensitivity. If three claims a year land at $12,000, added retention is 3 × ($12,000 − $5,000) = $21,000, so the trade nets about $25,000 in favor. If six claims a year land between $10,000 and $25,000, the saving disappears. The two liability claims at $85,000 and $140,000 behave identically at either deductible level, so they neither justify nor defeat the change. The open $300,000 completed-operations reserve is the genuine balance-sheet exposure and is also unaffected.
The $2 million umbrella at $18,500 is inexpensive for the gap it fills and is contractually required, so buy it - but confirm the exhaustion and maintenance-of-underlying wording, because an umbrella does not automatically drop down over an eroded primary aggregate.
Recommendation: accept the $25,000 deductible conditional on the loss distribution, and redirect part of the saving into backing sensors and telematics. The 22 low-severity auto claims are the controllable driver of total cost, not the deductible.
2. Assume the company adopts the $25,000 deductible. What must the broker communicate to the general contractors who hold certificates, and what on the ACORD 25 does or does not change?
Read the worked answer
Nothing on the ACORD 25 becomes false. The form shows policy limits, not retentions, and there is no deductible field. If the certificate shows $1 million per occurrence and $2 million general aggregate, that remains an accurate statement of the limits, so do not invent a typed note in the description box to compensate.
Disclose the retention separately and in writing - cover email, renewal summary, or a short letter to each certificate holder that has a deductible or indemnity clause in its subcontract. Many subcontracts require the subcontractor to absorb the deductible, cap it, or state it will not be passed through; others are silent, which means the named insured owes it under the policy, and a general contractor's recovery on a covered claim is effectively reduced by the retention regardless of its additional insured status.
Then check what kind of retention it is. A true deductible means the insurer pays defense and bills the insured. A self-insured retention means no defense until the SIR is exhausted, and defense costs may erode it - a materially worse outcome on a claim shaped like the $85,000 slip-and-fall. Also confirm the deductible applies per occurrence and not per claimant; a per-claimant deductible on a multi-injury event changes the arithmetic entirely.
