Why PEOs Request Loss Runs

The Single Most Important Document in PEO Underwriting

Loss runs are the record of every workers comp claim your business has had over the past three to five years. Every PEO asks for them because they are the single most important document in underwriting. Your loss runs reveal your actual claims experience, which drives your workers comp pricing more than any other factor. Understanding what loss runs show and how to get them gives you a head start on better pricing.

What We Evaluate

Key Underwriting Factors

Claim Frequency

How often you have claims. Frequent small claims raise your risk profile more than one large claim because frequency predicts future losses.

Claim Severity

The total cost of each claim. Severe claims with large payouts push your risk profile and your pricing up.

Open Versus Closed

Open claims with reserves still outstanding signal future cost. Closed claims with final costs are weighted differently.

Claims Trend

Is your loss history improving or worsening? A downward trend earns better pricing than a flat or upward trend.

Reserve Adequacy

The underwriter checks whether reserves on open claims are adequate. Under-reserved claims may grow and signal more risk.

Class Code Accuracy

Loss runs confirm your claims are assigned to the right class codes. Misclassified claims can distort your risk profile.

What Loss Runs Are

What Loss Runs Actually Are

Loss runs are a report from your current workers comp carrier that lists every claim your business has filed over a specified period, usually three to five years. For each claim, the report shows the date, the type of injury, the amount paid, the amount reserved, and whether the claim is open or closed. The PEO underwriter uses this report to build your risk profile and set your workers comp pricing.

Why PEOs Need Them

Why Every PEO Asks for Loss Runs

Workers comp pricing is based on your actual claims experience, not just your industry average. Loss runs are the only document that shows your actual experience. Without them, the underwriter can only price you on industry averages, which means you pay for the average risk in your industry even if your claims are better. With loss runs, the underwriter can price you based on your real history, which can save you significantly if your claims are better than average.

How to Get Them

How to Get Your Loss Runs Before You Apply

Request loss runs from your current workers comp carrier. Most carriers provide them free within two weeks. Ask for three to five years of history in a valued format, which shows paid and reserved amounts. If your carrier is slow, a broker can often expedite the request. Having your loss runs in hand before you apply to a PEO can cut your underwriting time in half and ensure your pricing reflects your actual claims experience.
