What is Self Insured Retention Programs (SIR)?
A Self Insured Retention (SIR) program is a structure where an organization retains responsibility for losses up to a set amount before an insurer’s excess layer begins to pay. SIRs function like a high deductible but are often handled differently for claims and loss control. SIR arrangements are commonly used alongside large-deductible placements, and you can learn more about placement options on the Large Deductible / Self Insured Retention Placements page.
Who needs it
SIRs are typically chosen by organizations with sufficient cash flow, a mature risk-management program and in-house claims handling or a third-party administrator. Typical buyers include clubs, associations, event organizers, contractors and facility operators that want control of smaller claims while transferring catastrophic risk. Employers with complex worker exposures may pair SIRs with excess workers’ compensation solutions such as Excess (SIR) Workers Compensation Insurance.
What it typically covers
Coverage under an SIR mirrors the policy that follows it, so it commonly responds to commercial liability and event liability claims, participant accident or spectator injury exposures, property damage and certain equipment losses. The insurer’s excess layer will respond after the organization’s retained amount is exhausted. Risk management considerations—such as site safety programs and loss-prevention measures—are integral to successful SIR use.
Risk scenario: an event organizer might retain the first $100,000 for a serious spectator injury before the excess policy responds.
Common exclusions or limitations
- Intentional acts, punitive damages, and known prior acts are frequently excluded.
- Some policies exclude professional services or pollution unless specifically endorsed.
- Coverage for commercial auto exposure or specialized equipment may be limited or require separate endorsements.
Factors that influence cost
Underwriting factors for SIR pricing include loss history and severity, industry and operations, payroll or revenue metrics, the quality of claims handling, and the controls in place to reduce frequency and severity. External market conditions and the size of the retention also affect premium and capacity.
Proof of insurance & compliance
Organizations that operate with an SIR should keep clear documentation of the retention terms, claims-handling procedures and certificates of insurance for vendors or venues. Some counterparties or regulators may require proof that the SIR is backed by a collateral or reimbursement agreement; in contexts where organizations manage their own program you may also see reference to broader Self Insurance Programs for compliance and funding structures.

Frequently Asked Questions
How does an SIR differ from a high deductible?
An SIR is retained by the insured and usually requires the insured to pay and manage claims up to the retention amount, whereas a high deductible may allow the insurer to handle claims and bill the insured for the deductible. Administrative differences and contract language are important.
Will an SIR reduce my insurance premium?
An SIR can lower premium by shifting smaller losses to the insured, but savings depend on retention size, loss history, and market conditions. It is not a guarantee of lower cost and should be evaluated with underwriting guidance.
Who handles claims under an SIR?
Claims are commonly handled by the insured or a third‑party administrator until the retention is exhausted; the excess insurer typically becomes responsible only after the SIR amount is paid.
