What is Reinsurers?
Reinsurers are companies that provide insurance to other insurers. They take on portions of risk from primary carriers to help stabilize losses, manage capital, and support larger or more complex programs. Reinsurance can be structured in many ways, from treaty and facultative arrangements to quota share and excess-of-loss contracts. For more on structured arrangements and program design, see Reinsurance Programs.
Who needs it
Primary insurers, captive insurance companies, and specialty carriers commonly use reinsurance. Intermediaries and brokers who place complex or high-severity risks also rely on reinsurance markets to offer capacity. Smaller carriers or those covering niche exposures — for example clubs, associations, event organizers, or manufacturers with product liability exposure — may purchase reinsurance to protect solvency and manage peak exposures. Many firms work with Reinsurance Intermediaries to access markets and structure placements.
What it typically covers
Reinsurance doesn't cover typical retail policyholders directly; it covers the insurer's portfolio. Typical protections include catastrophic event layers, aggregate stop-loss coverage, and treaty-level sharing for casualty, property, or specialty lines. Related coverage types often involved in program design include commercial liability, property coverage, and commercial auto exposure. Reinsurance can be tailored to specific product lines or to aggregate loss experience, helping carriers stabilize results over time.
Common exclusions or limitations
Reinsurance contracts frequently exclude known prior losses, intentional acts, and certain war or nuclear exposures. Limitations may include reinstatement provisions, co-participation clauses, and sub-limits on specific perils. Underwriting factors and policy terms at the primary level directly affect what reinsurance will accept, so clear disclosures and accurate loss reporting are essential to avoid coverage disputes.
Factors that influence cost
Pricing depends on exposure concentration, historical loss experience, reinsurance capacity, and broader market conditions. Underwriting factors such as attachment points, limits, and occurrence vs. claims-made arrangements also matter. Macro drivers like natural catastrophe activity and capital availability in the reinsurance market can push rates up or down.

Proof of insurance & compliance
Primary insurers provide certificates, binders, and contract copies to reinsurers to document coverages and obligations. Regulatory and rating agency requirements may dictate surplus and capital reporting; compliance practices vary by jurisdiction. Clear documentation of policy terms, endorsements, and loss development is critical for claims settlement and regulatory reviews.
How to get a quote
If you represent a primary insurer or captive evaluating reinsurance, prepare loss histories, exposure summaries, and current policy forms before requesting terms. Market access often requires collaboration with brokers or intermediaries who specialize in placement and negotiation. When reviewing program options, talk to your agent about available structures and appetite — or visit talk to your agent to request a quote through the marketplace. A common risk scenario is a large natural catastrophe that produces multiple high-severity claims, demonstrating why many carriers layer protection across several reinsurers.
Frequently Asked Questions
What is the difference between facultative and treaty reinsurance?
Facultative covers single, specific risks negotiated one-by-one; treaty covers a portfolio of risks under a standing agreement between parties.
Who negotiates reinsurance terms?
Insurance companies often work with reinsurance brokers or intermediaries to negotiate terms, access capacity, and place coverage in global markets.
Can reinsurance protect against catastrophic losses?
Yes. Reinsurance is commonly used to provide catastrophic layers and excess-of-loss protection to limit an insurer’s exposure to very large or aggregate losses.
