Your renewal is two weeks out. Your broker sends over a checklist, and near the bottom is a request you weren't expecting: three to five years of loss run reports from your previous carriers. You've never heard the term. You forward it to your office manager, but nobody knows what it is or how to get it.
This is how most business owners encounter loss runs. Not during a calm planning session, but under deadline pressure when a renewal, a contract review, or a new quote is already in motion. And because loss runs can take up to 10 days to arrive from some carriers, a late request can delay coverage, stall a deal, or put you in a weaker negotiating position than you need to be.
Understanding how they work before you need them gives you more control over the process and a stronger position at renewal. This guide breaks down what loss runs are, what they include, why insurers care, and how to use them strategically.
Key Takeaways
- Loss run reports are your verified claims history and a core input to insurance pricing and eligibility.
- Insurers focus on frequency, severity, and reserves when evaluating your risk profile.
- Clean or well-contextualized loss runs improve your negotiating position and coverage terms.
- A strong broker uses your loss runs to advocate for better pricing, not just pass them along to carriers.
- With the right guidance, loss runs shift from an administrative hurdle to a strategic tool.
What Is a Loss Run Report?
A loss run report is the formal document summarizing your company's claims history over a defined period, typically three to five years. It is issued by your current or past insurance carrier and is required by any carrier quoting new coverage.
Think of it the way lenders think about credit reports. A clean record signals lower exposure and can help you secure more competitive premiums. Frequent or high-severity claims prompt underwriters to ask what happened and what has changed since.
Loss run reports are standardized, verifiable, and dated, meaning a broker or insurer can rely on them during underwriting. If you've switched insurers in recent years, you may need multiple reports to provide a complete picture.
Loss runs apply across nearly all commercial insurance lines, including:
- General Liability
- Business Property
- Workers' Compensation
- Professional Liability/Errors & Omissions (E&O)
- Cyber
- Business Owner's Policies
- Commercial Auto (and in some cases, Hired and Non-Owned Auto)
What's Included in a Loss Run Report?
Loss run reports generally contain five categories of information.
- Your Policyholder Details: Business name, policy number, and policy term or terms.
- A Chronological List of Claims: For each claim, insurers list the date of incident, date you reported the claim, a description of what happened, and the coverage line involved (General Liability, Property, Workers' Comp, and so on).
- Financial Impact: Legal expenses, payments made to resolve the claim, indemnity or settlement amounts, and vendor or remediation costs depending on coverage.
- Open vs. Closed Status: Open claims carry more uncertainty, so underwriters look carefully at whether the claim is still active, what remains unresolved, and the expected duration or litigation activity.
- Reserves: For any open claim, insurers set aside reserves, the amount they anticipate paying before the claim is closed. These reserve amounts can influence your pricing even before costs are finalized.
If you have no claims activity, the report will simply state "No losses reported." This is a valuable signal for insurers, especially when paired with industry benchmarks and context from your broker.
When You Need a Loss Run Report
Loss run reports surface at predictable moments in a company's insurance cycle. Here are the situations where you'll almost always be asked for one.
- When you're shopping for new coverage. Any insurer quoting new General Liability, Property, Workers' Compensation, or Professional Liability coverage will require three to five years of loss runs before binding a policy. Without them, underwriting cannot move forward.
- When you're renewing existing policies. Renewals with significant changes, like higher limits, new operations, expanded locations, or prior-year claims, often trigger a fresh request. If you're seeing unexpected premium increases at renewal, your loss runs are the first place your broker should look.
- When you're entering a contract or partnership. Enterprise clients, vendors, and commercial landlords may request loss runs during their risk review process. For technology companies pursuing enterprise deals, this requirement often surfaces during procurement alongside Certificates of Insurance and specific limit thresholds.
- When you're raising capital or seeking financing. Investors and lenders sometimes require loss runs as part of diligence, particularly for companies with physical operations, employee-intensive environments, or regulatory exposure. Founders preparing for a Series A or later fundraise should expect Directors & Officers (D&O) and Cyber loss runs to be part of the process.
- When you're evaluating your own risk profile. Many businesses proactively review loss runs annually to identify trends, like frequent injuries, recurring property damage, or operational gaps, and use those insights to strengthen safety or compliance programs.
How Loss Runs Affect Your Premium
One of the most common points of confusion is the relationship between loss runs and pricing. A clean loss run is one of the strongest signals you can send to an underwriter, but it's not the only factor that determines your premium.
Insurance pricing is shaped by a combination of inputs. Your claims history is central, but carriers also weigh your revenue, headcount, industry vertical, geographic footprint, and the broader market environment. This means your premium can increase at renewal even with a spotless claims record if your business has grown significantly, if you've raised capital, or if carrier loss ratios have shifted across their portfolio.
This is exactly where a knowledgeable broker adds value. Rather than simply passing your loss runs to a carrier and waiting for a quote, a strong broker uses your clean history as evidence in a negotiation. They contextualize your claims record, benchmark your pricing against similar businesses, and push back on rate increases that aren't justified by your risk profile.
How to Interpret Your Loss Run Report
The value of a loss run isn't just in the data but in how you interpret it. Three factors matter most.
- Frequency: Repeated similar claims can indicate systemic issues. Multiple small claims often raise more concern than a single large one because they suggest a pattern rather than an isolated event.
- Severity: One catastrophic claim may not define your profile if you have an otherwise clean history. Underwriters distinguish between isolated incidents and patterns of exposure.
- Reserves: Large reserves on open claims can affect pricing until they are revised or the claim is closed. Understanding what's driving reserve levels helps you have a more informed conversation with your broker at renewal.
A knowledgeable broker can help you contextualize the record, providing underwriters with operational history, changes you've made, or relevant explanations that clarify your risk posture. A closed claim that was baseless, for example, doesn't negatively impact your file or future pricing, but without context from your broker, an underwriter might not know that.
Loss Runs for General Liability: What They Show and Why They Matter
Because General Liability Insurance is one of the most common and most claims-active coverages for businesses, General Liability loss runs are often a deciding factor during underwriting. These reports highlight incidents involving bodily injury (slip-and-fall accidents), property damage (equipment accidentally damaged at a client site), and personal and advertising injury.
Underwriters aren't just looking at the claim amount. They're looking at frequency, severity, and cause. A single high-value claim like storm damage may be viewed differently than three similar small claims that suggest chronic issues.
How to Request a Loss Run Report
You obtain loss run reports from your current or past insurance carriers. Most insurers allow you to request them in three ways: through your online portal, by contacting your agent or broker, or by emailing the carrier directly.
When requesting a report, always specify the policy or policies you need, the timeframe (often three to five years), and your required delivery date. Insurers are required by most states to provide loss runs within 10 days of receiving your request. If you don't receive your report in a timely manner, you can escalate through your state insurance department.
How Long Does It Take to Receive Loss Runs?
Turnaround depends on carrier systems and volume, but generally:
- Some carriers deliver within 24 hours
- Most provide reports within three to five business days
- Delays beyond 10 days may violate state guidelines
If you need new coverage quickly, like completing a client contract, requesting loss runs early prevents unnecessary last-minute stress.
How Loss Runs Affect Your Ability to Switch Insurance Providers
Any insurer quoting a new policy will require loss runs before binding coverage. Without them, the carrier cannot accurately price or evaluate your risk. This means starting your renewal or shopping process early, requesting loss runs before you begin quoting, and keeping copies of each report for future use.
If you're expanding, entering new markets, or bidding on enterprise contracts, having updated loss runs on file helps your broker advocate for stronger terms. A broker experienced in your industry can use your loss runs to tell a story to carriers: not just what happened, but what it means and how your business has responded.
Common Mistakes That Weaken Your Position
Even with a clean claims history, how you handle your loss runs can affect the outcome.
- Waiting until the last minute to request them. Loss runs can take up to 10 days. If your renewal or a new quote is time-sensitive, late requests create unnecessary delays that put you in a reactive position.
- Not providing context around past claims. A claim on your record without explanation looks worse than the same claim with a note about what you changed afterward. Your broker should be framing this narrative for the underwriter, not leaving the data to speak for itself.
- Assuming clean history guarantees flat pricing. Growth in revenue, headcount, or capital raised can drive premium increases independently of claims history. Understanding this prevents frustration at renewal and helps you have a more informed conversation with your broker.
- Skipping an annual review. Reviewing your loss runs proactively, at least once a year, helps you spot trends and address operational risks before they become underwriting concerns.
Best Practices for Keeping Your Loss Runs Strong
Loss runs improve when your operations improve. Businesses that treat claims history as a management tool tend to secure better terms over time.
- Conduct annual safety and risk reviews. Don't wait for a claim to surface a problem. A yearly review of your operations, facilities, and employee practices helps you identify and address risks before they become claims. Underwriters respond well to companies that can demonstrate proactive risk management.
- Update training or equipment when patterns appear. If your loss runs show recurring claims of the same type, whether slip-and-falls, equipment damage, or cyber incidents, that pattern signals a systemic issue. Addressing it with updated training, new protocols, or equipment upgrades shows carriers you're taking corrective action.
- Document corrective actions after a claim. A claim on your record is less damaging when paired with evidence of what changed afterward. If you updated a process, hired a safety officer, or implemented new controls, document it. Your broker can present that context to underwriters at renewal.
- Keep lines of communication open with your broker. Your broker should know about operational changes, new locations, new hires, or significant contracts before renewal, not after. The more context they have, the better they can frame your risk profile to carriers.
- Close claims promptly when issues are resolved. Open claims carry reserves that can affect your pricing even before costs are finalized. Working with your broker and carrier to close resolved claims promptly reduces the reserve impact on your renewal pricing.
- Implement cybersecurity controls if applicable. For tech and professional services companies, cyber loss runs are increasingly scrutinized at renewal. Strong security controls, including multi-factor authentication, endpoint detection, and employee training, can improve your terms and in some cases are required as a condition of coverage.
Turn Your Loss Runs Into Leverage
Loss runs shouldn't be a last-minute scramble or an administrative hurdle you hand off to someone else. They're the clearest record of how your business interacts with risk, and in the right hands, they're one of the most effective tools you have at renewal.
The difference between a business that gets better terms and one that doesn't often comes down to preparation: requesting loss runs early, understanding what's in them, and working with a broker who knows how to use that history to your advantage rather than just passing it along to a carrier.

Frequently Asked Questions
Do all insurers require loss runs?
Any insurer quoting or renewing commercial insurance will typically ask for at least three years of loss runs.
Can I get a quote without providing loss runs?
Carriers may give an early estimate, but they cannot finalize or bind coverage until loss runs are provided.
What if I've never had commercial insurance before?
If you're a first-time buyer, you won't have loss runs. Insurers simply price your policy based on industry, size, and operations.
What if my previous carrier won't send the report?
Most states require delivery within 10 days. If they fail to comply, you can escalate to the state insurance department.
Do loss runs cover every type of commercial policy?
Loss runs exist for nearly all lines with claims activity, including General Liability, Business Property, Workers' Compensation, E&O, and Cyber.
Why are reserves important?
Reserves reflect the insurer's estimated future payout on an open claim. High reserves can influence pricing until the claim closes.
Does one major claim hurt more than several small ones?
Not always. One unusual, high-severity claim may be viewed as an isolated event. Multiple similar claims often raise more concern because they suggest a pattern.
How often should I review my loss runs?
At least once per year or any time you add new operations, sign major contracts, or prepare for renewal.
How do loss runs affect my premium?
Your claims history is a major pricing input, but it's not the only one. Revenue, headcount, industry, and market conditions also play a role. A clean loss run strengthens your negotiating position, but it doesn't guarantee flat pricing if your business has grown.
Can I dispute information on my loss run report?
If you believe a claim is reported inaccurately, contact your carrier to request a correction. Your broker can also advocate on your behalf. Errors in loss runs are uncommon but worth checking, especially before a renewal or new quote.
