Quick answer
Loss run analysis before renewal helps identify cost drivers, correct claim errors, and present a cleaner risk profile to underwriters. This guide shows how to pull, review, and leverage loss runs for better renewal outcomes—without guarantees, but with stronger preparation.
Key Takeaways
- Request loss runs 90-120 days before renewal to allow time for corrections and reserve negotiations
- Focus on loss ratio: Underwriters care more about loss ratio (claims vs. premium) than total claim count
- Close stale reserves aggressively: Open reserves older than 24-36 months signal ongoing risk to underwriters
- Document corrective actions for every significant claim: Show underwriters you’ve addressed root causes
- Create a one-page loss summary: Control the narrative around your risk profile with clear, proactive documentation
What to pull from your loss runs
- 5-year claims summary: total incurred, paid, and reserves by policy year.
- Open reserves: any claims with remaining financial exposure.
- Claim types by frequency: pattern showing repeat incidents (slips/falls, auto, property).
- Loss ratio by policy: compare your losses to premium paid.
- Subrogation status: confirm whether carriers pursued recovery from third parties.
Loss Ratio Impact on Premium
| Loss Ratio Range | Expected Renewal Impact | Underwriting Response | Recommended Action |
|---|---|---|---|
| Under 30% | Flat to -10% | Preferred account, competitive quotes | Document success, negotiate hard |
| 30-50% | Flat to +5% | Standard account, market pricing | Highlight corrective actions |
| 50-70% | +10-25% | Moderated risk, reduced carrier options | Address frequency claims, show improvements |
| 70-100% | +25-50% | Challenging account, limited markets | Aggressive loss control, consider higher deductible |
| Over 100% | +50-100% or non-renewal | Poor risk, surplus lines likely | Risk management overhaul, specialty broker |
Reserve Status Comparison
| Reserve Status | Definition | Underwriting Signal | Action Required |
|---|---|---|---|
| Closed - No Payment | Claim resolved, no cost | Positive, shows resolved issue | None, include in summary |
| Closed - Paid | Claim resolved, amount paid | Neutral to negative depending on size | Document corrective measures |
| Open - Active Reserve | Ongoing claim with funds set aside | Negative, indicates ongoing exposure | Request reserve review, prepare explanation |
| Open - Stale (24+ months) | Old claim with unused reserve | Very negative, suggests poor follow-up | Demand reserve closure or reduction |
| Reopened | Previously closed claim reactivated | Highly negative, uncertainty | Investigate immediately, document |
7-step loss run workflow before renewal
1. Request loss runs 90-120 days before renewal
Contact your current carrier or broker and request full loss runs for the past 5 years, including open and closed claims with incurred amounts. Early requests allow time for corrections or clarifications before underwriting begins.
2. Verify claim accuracy line by line
Review each claim for correct dates, amounts, and descriptions. Errors like inflated reserves, wrong policy numbers, or duplicate entries can artificially increase perceived risk. Document discrepancies and request corrected reports promptly.
3. Identify and close stale reserves
Look for claims with open reserves older than 24-36 months with no recent activity. Ask your carrier to evaluate whether reserves can be closed or reduced. Lingering open reserves signal ongoing exposure to underwriters.
4. Categorize claims by preventability
Separate claims into three buckets: preventable (training/process fixable), not preventable (true accidents/external), and frequency-driven (repeat incidents). This helps focus loss-control efforts where they matter most and shows proactive management.
5. Document post-loss corrective actions
For each significant claim, list what changed afterward—new safety protocols, equipment upgrades, training programs, or process changes. Underwriters respond better when they see concrete responses to loss patterns.
6. Build a one-page loss summary
Create a clean summary sheet showing 5-year loss history, closed vs. open, loss ratio by line, and key corrective actions. Bring this to broker meetings and renewal discussions to control the narrative around your risk profile.
7. Share proactively with competing carriers
When shopping quotes, provide your loss summary and corrected runs upfront. Transparency positions you as a well-managed account and can improve pricing or appetite from new carriers.
Common mistakes to avoid
- Waiting until renewal week: rushing limits your ability to correct errors or negotiate reserves.
- Ignoring small frequency claims: multiple small losses signal poor loss control even if severity is low.
- Focusing only on big claims: frequency concerns underwriters more than one large loss for most SMBs.
- Hiding past losses: omissions discovered during underwriting can jeopardize coverage or trust.
- Not challenging outdated reserves: stale reserves can linger for years if not questioned.

FAQ
What is a loss run?
A loss run is a claims report from your insurance carrier showing all claims for a policy or account over a specified period, including claim amounts, status, and reserves. It is the primary document underwriters use to assess your claims experience.
How far back should loss runs go?
For renewal planning, request at least 5 years of loss history. Many underwriting models use a 3-year lookback, but 5 years provides fuller context and helps identify longer-term patterns or one-time anomalies.
Can correcting errors on loss runs actually lower premium?
It can help. Correcting inflated reserves, removing duplicate entries, or closing stale claims improves your loss ratio presentation, which may lead to better pricing or expanded carrier appetite. Results vary by market and carrier.
What if I have no losses but premium still increased?
Carriers also consider broader market factors (reinsurance costs, inflation, catastrophic losses) and your specific risk profile (payroll growth, new operations, location). Clean loss runs help, but they don’t control external rate pressure.
Should I share loss runs with competitors before quoting?
Yes, with strategic guardrails. Share a summarized version showing key figures and corrective actions. Full reports can go to finalists. Transparency often improves quote quality by reducing underwriting uncertainty.
What loss ratio do underwriters consider good?
Most carriers prefer loss ratios under 40%. Below 30% is excellent and often qualifies for preferred pricing. Above 60% raises concerns; above 80% typically triggers non-renewal or substantial increases.
How do I close stale reserves on my loss run?
Contact your carrier’s claims department and request reserve review for any claim with no activity in 18+ months. Ask specifically for “reserve closure” or “reserve reduction” documentation. Get written confirmation of any changes.
What’s the difference between incurred and paid?
Incurred includes both amounts already paid plus reserves set aside for future payments. Paid is only what has been disbursed. Underwriters focus on incurred because it represents total carrier exposure.
Can one large claim ruin my insurance costs?
One large claim is generally better than multiple small claims (frequency vs. severity). A single catastrophic event with clear cause and corrective action is easier to explain than a pattern of repeat incidents suggesting poor risk management.
Should I hire a claims consultant for loss run review?
For complex claims or multi-year patterns, yes—consultants often identify errors and negotiate reserves better than business owners. For straightforward histories with few claims, a careful self-review may suffice.
