What Are Loss Runs in Insurance?
Loss runs are reports generated by insurance companies that summarize a policyholder’s claim history over a specific period. These documents list each claim filed under a particular insurance policy, including the date of loss, type of claim, amount paid, and claim status.
Loss runs are typically requested by policyholders, brokers, or potential new insurers to evaluate the risk profile of an individual or business before issuing or renewing a policy.
For commercial insurance, loss runs are critical in assessing the historical loss experience of a business. Insurers rely on these records to understand the frequency and severity of past claims, which helps them make underwriting decisions. The information contained in loss run reports plays a central role in determining premium rates, policy terms, and eligibility for coverage.

Why Do Loss Run Reports Matter?
Loss runs directly affect how insurers evaluate risk and price policies. They provide a factual record of past claims, which helps all parties make informed decisions.
Guide underwriting decisions: Insurers use loss runs to assess risk before issuing or renewing a policy. A history of frequent or severe claims may lead to stricter terms or declined coverage.
Impact premium pricing: Premiums are tied to past loss experience. Businesses with fewer or lower-cost claims often receive better rates, while poor loss history can increase premiums.
Support risk assessment: Loss runs show patterns in claims, such as recurring incidents or high-cost events.
Enable comparison across insurers: When seeking quotes, loss runs allow multiple insurers to evaluate the same risk data.
Highlight areas for risk improvement: Policyholders can use loss runs to identify problem areas.
Affect policy terms and conditions: Insurers may adjust deductibles, limits, or exclusions based on claim history.
Required for policy renewal or switching carriers: Most insurers request recent loss runs before offering coverage.
What Information Is Included in a Loss Run Report?
Policy Number and Coverage Period
A loss run report includes the policy number, which identifies the insurance contract to which the claims relate. This number ensures that all claims listed are associated with the specific policy being evaluated.
Alongside the policy number, the coverage period is stated, defining the timeframe during which the reported claims occurred. This helps insurers and insureds confirm that the information is relevant to the period under review and ensures no claims outside the coverage window are considered.
Accurate policy numbers and coverage periods are necessary for proper analysis. Insurers use this data to confirm that all claims fall within the expected timeframes, which is important during renewals or when switching carriers. Discrepancies can lead to misunderstandings, delays, or disputes.
Claim Dates and Descriptions
Each claim listed on a loss run report includes the date the incident occurred and a brief description of the event. The claim date shows when losses took place and can highlight patterns or clusters of incidents over time.
The description outlines the nature of the claim, such as a property loss, liability event, or workers’ compensation incident, which helps in assessing the type and impact of each loss.
Claim dates and descriptions allow insurers and policyholders to track risk over time. Repeated claims of a similar nature within a short period may indicate a recurring problem or a need for improved risk management. Isolated incidents may be less concerning.
Type of Claim
Loss run reports categorize claims by type, such as property damage, general liability, auto, or workers’ compensation. Identifying the type of claim helps insurers assess the nature of risks associated with a policyholder.
For instance, a business with frequent property damage claims may require different underwriting considerations than one with more liability-related claims.
The type of claim also influences how insurers price policies and determine endorsements or exclusions. A pattern of specific claim types can signal operational issues or highlight areas where risk controls may be lacking.
Paid Amounts and Reserves
A key component of loss run reports is the financial breakdown of each claim, including the amount already paid and the reserve amount set aside for future payments.
The paid amount reflects what the insurer has disbursed to date for the claim, while the reserve is an estimate of the remaining liability.
Together, these figures show the financial impact of each claim on both the policyholder and the insurer. Insurers use these numbers to assess the overall cost of claims and forecast future liabilities.
Policyholders can review this information to understand how claims may affect their premiums and to identify trends that require operational or risk management changes.
Claim Status (Open vs. Closed)
Loss run reports specify the current status of each claim, categorizing them as either open or closed.
An open claim has not yet been fully resolved; payments may still be pending, or further investigation may be required. A closed claim is settled, with all payments completed and no further action anticipated.
This distinction matters. Open claims represent ongoing liabilities and potential future costs, while closed claims provide a finalized record of losses.
How Loss Runs Are Used By Insurers, Underwriters, and Buyers
How Loss Runs Affect Insurance Premiums Set By Insurers
Loss runs influence insurance premiums by providing a record of past losses. Insurers use this data to assess the risk level associated with a policyholder. A clean loss run, showing few or no claims, often results in lower premiums because it suggests lower financial risk.
A history of frequent or high-value claims often leads to increased premiums. Insurers may apply surcharges, adjust deductibles, or limit coverage to offset higher expected loss. For example, repeated property damage claims might result in a higher property insurance rate or additional risk mitigation requirements.
The total cost of claims, including paid amounts and open reserves, also influences pricing. Even if a policyholder has few claims, large open reserves can signal unresolved liabilities that affect future premiums. Underwriters use the financial data in loss runs to project potential payout exposure, which feeds into premium calculations.
How Underwriters Use Loss Runs
Underwriters rely on loss runs to evaluate risk and decide whether to offer coverage. The loss run helps them identify patterns, such as recurring claim types or frequent losses over a short period, which can signal weak risk controls or high exposure.
The timing, frequency, and severity of past claims are important. A few large but infrequent claims may be viewed differently from many small recurring ones. Underwriters assess whether the losses were isolated events or indicators of ongoing issues.
Loss runs also help underwriters determine whether a risk aligns with the insurer’s appetite. If the report reveals high-risk exposures, the underwriter may adjust policy terms by increasing deductibles, applying exclusions, or declining coverage.
How Insurance Buyers Can Request a Loss Run Report
To request a loss run report, a policyholder must contact their current or former insurance carrier, usually through an agent or broker. Most states require insurers to provide these reports within a set timeframe, often 10 business days, once a written request is submitted.
The request should include the policyholder’s name, policy number or numbers, and the desired timeframe of the report. If multiple years or lines of coverage are needed, this should be clearly stated. Many insurers accept requests by email or online portal, but confirmation of receipt is recommended.
Brokers often handle these requests during renewal or marketing. It is advisable to request loss runs at least 30 days before a policy renewal to allow time for review and quoting. Keeping updated loss runs on file is a best practice for businesses that want flexibility in their insurance options.

Common Mistakes When Reviewing Loss Runs
Ignoring Open Claims
One common mistake is overlooking open claims. These represent unresolved liabilities that can affect future premiums and risk assessments.
Failing to account for open claims may lead to underestimating potential losses. Policyholders should monitor these claims and work toward resolution to reduce long-term impact.
Misinterpreting Reserves
Another frequent error is misunderstanding reserve amounts. Reserves are estimates of future payments, not guaranteed payouts.
Misinterpreting them can lead to incorrect assumptions about financial exposure. Since reserves can change over time, they should be reviewed alongside claim details and trends.
If needed, clarification from the insurer can help avoid misunderstandings.
Using Outdated Reports
Relying on outdated loss run reports can lead to poor insurance decisions. Claims activity changes over time, and older reports may not reflect recent developments.
Using outdated data can distort risk assessments, affecting premiums and coverage eligibility.
To avoid this, request the most current loss run available, especially during renewals or when switching providers. Regular updates support accurate decision-making.
Overlooking Claim Trends
A common mistake is focusing only on individual claims rather than identifying broader patterns over time. Loss runs are most useful when used to detect trends, such as recurring incidents, seasonal spikes, or increasing claim severity.
Ignoring these patterns can result in missed opportunities for risk reduction. For example, repeated slip-and-fall claims at a single location may indicate a safety issue that needs attention.
Analyzing trends helps insurers adjust pricing and terms accurately, while businesses can implement targeted risk management strategies to reduce future losses.
