Deductible and self-insured retention (SIR) are both mechanisms by which an insured retains some portion of the financial risk before their insurance responds. They serve similar purposes - aligning the insured's economic interests with loss prevention - but they work differently and have distinct implications for contract compliance and third-party protection.
A deductible is an amount the insured pays before the insurer begins paying - but the insurer controls the claim from the start. A self-insured retention (SIR) is an amount the insured must fund entirely before the insurer's obligations are triggered at all.
- Insurer controls the claim from day one
- Insurer pays full amount, seeks reimbursement
- Full policy limit available to third parties
- Generally less risky for contract compliance
- Insured controls claim until SIR is exhausted
- Insurer has no duty until SIR is fully paid
- Third-party recovery depends on insured funding SIR
- Can impair practical value of insurance
Understanding the difference matters because contracts frequently address deductibles and retentions, specifying maximum allowable amounts or prohibiting SIRs altogether.
What a Deductible Is
A deductible is an amount the insured must pay toward a covered claim before the insurer begins paying. The insurer takes control of the claim - investigating, defending, and settling - and pays the balance above the deductible.
Example: A general liability policy has a $25,000 deductible. A claim settles for $100,000. The insured pays $25,000; the insurer pays $75,000.
Key characteristics of a deductible:
- The insurer controls the claim from the beginning, including the defense
- The insurer pays the full settlement or judgment, then seeks reimbursement of the deductible from the insured
- The full policy limit remains available to third-party claimants regardless of the deductible amount
- The insurer's coverage obligation is not affected by whether the insured reimburses the deductible
Because the insurer controls the claim and third parties can recover the full policy limit regardless of the deductible, deductibles are generally less concerning from a contract compliance perspective than self-insured retentions.
What a Self-Insured Retention Is
A self-insured retention (SIR) is an amount the insured must pay out of its own resources before the insurer's obligations are triggered at all. Unlike a deductible, the insurer does not step in until the SIR is fully exhausted.
Example: A general liability policy has a $100,000 SIR. A claim settles for $300,000. The insured handles and pays the first $100,000; the insurer pays the remaining $200,000.
Key characteristics of an SIR:
- The insured controls (and must fund) the claim up to the SIR amount
- The insurer has no obligation - including no duty to defend - until the SIR is exhausted
- The insurer's available limit begins at the SIR threshold, not from dollar one
- A third-party claimant's ability to recover the full policy limit depends on the insured's ability to fund the SIR
This last point is what makes SIRs consequential for compliance. If a vendor has a $500,000 SIR and faces a claim but cannot fund the retention (due to financial distress, cash flow problems, or simply the scale of multiple simultaneous claims), the insurer does not step in until the SIR is satisfied. The third-party claimant - potentially your organization as an additional insured - faces a gap.
Why Contracts Limit Deductibles and Retentions
Commercial contracts address deductibles and SIRs for this reason: they can impair the practical value of the insurance you required the vendor to carry. A $5 million general liability policy sounds adequate, but if it sits above a $2 million SIR held by a vendor with limited financial resources, the effective protection may be far less.
Contract provisions commonly include:
- A maximum allowable deductible per occurrence (e.g., no deductible exceeding $25,000)
- A prohibition on SIRs above a specified threshold, or a prohibition on SIRs entirely
- A requirement that, if an SIR exists, the vendor demonstrate financial capacity to fund it (via financial statements or a bond)
How Deductibles and Retentions Appear on COIs
Deductibles and SIRs are generally not shown on a certificate of insurance. The ACORD 25 form does not include a dedicated field for these amounts. This is a significant limitation of the COI as a compliance document.
There are two ways to address this limitation:
- Require the vendor to disclose deductibles and SIRs in the certificate's description of operations box - some sophisticated compliance programs include this as an explicit COI requirement
- Request a copy of the policy declarations page - the declarations will show the deductible or SIR structure directly
If your contract limits deductibles or prohibits large SIRs, and you cannot verify these amounts from the COI alone, the contract should include an explicit representation requirement and the right to request policy declarations.
Umbrella Policies and Retained Limits
Umbrella policies sometimes include a retained limit - an amount the insured must pay before the umbrella's coverage responds, similar to an SIR but at the umbrella layer. These retained limits may appear on the COI in the umbrella section; review them against any contractual limitations.
How Bramble Helps
Bramble flags disclosures of deductibles or self-insured retentions that appear on submitted COIs and alerts compliance reviewers when contracts specify maximum deductible or retention amounts. When the COI is silent on these amounts, Bramble notes that additional verification may be needed to confirm compliance with contract terms.
