An HVAC company in Gainesville spends three weeks preparing a bid for a maintenance contract on a group of medical office buildings. The bid is rejected before anyone reads the pricing. The property manager’s prequalification requires a workers’ compensation experience modification factor at or below a set number, and the company’s mod is above it because of a run of small claims two and three years ago. The owner had never looked at the number until it cost him the job.
The experience modification factor, usually called the mod or the EMR, is the one part of a workers’ compensation premium that belongs entirely to your business. It changes what you pay, it follows you for years, and more and more customers use it to decide whether you can bid on their work at all.
What the Mod Is
The mod compares your actual workers’ compensation losses with the losses expected for a business of your size in your classifications. A mod of 1.00 means your losses are about average. A mod below 1.00, such as 0.85, is a credit that reduces your premium, and a mod above 1.00, such as 1.20, is a debit that increases it. The mod is applied directly to the premium, so a 1.20 mod adds about twenty percent and a 0.85 mod takes off about fifteen.
In Florida, the mod is calculated by the National Council on Compensation Insurance using rules that apply the same way at every carrier. Your carrier does not set it, and changing carriers does not reset it. Our guide to how much workers’ compensation costs in Florida shows how the mod fits into the premium alongside payroll and class codes.
Who Gets One
A business needs enough workers’ compensation premium history to qualify for its own mod. New businesses and very small employers below the eligibility threshold are rated at 1.00, which means their premium is not adjusted up or down for their own loss history. Once a business grows past the threshold, NCCI begins producing a mod for it each year. The eligibility threshold changes periodically, so ask your agent whether your business currently qualifies.
How It Is Calculated
The calculation uses three years of payroll and claims, and it skips the most recent year, because those claims are usually too new to be valued accurately. A policy renewing this year is rated on roughly the three policy years before last year. That lag is why a bad year affects the mod for three renewals and why improvements take time to show up.
Within that window, NCCI compares your losses with the losses expected for your payroll in each class code. It does not treat every dollar of a claim the same way. The first portion of each claim, called primary losses, counts fully, while the rest of a large claim, called excess losses, is weighted much less heavily. Claims that involve only medical treatment, with no lost time from work, are generally weighted less than lost-time claims. The practical result is that the number of claims matters more than their size.
Why Frequency Matters More Than Severity
This is the part most owners get backwards. Five small claims of a few thousand dollars each can hurt a mod more than one serious claim of much larger value, because each small claim counts almost entirely in the primary layer, while most of the large claim falls into the excess layer, which is discounted. The rating system treats frequency as a better predictor of future losses than one unlucky accident.
That has a direct consequence for restaurants, warehouses, contractors and any business where minor injuries are routine. Cuts, strains and slips that get treated and forgotten are exactly the claims that move the mod. Non-slip footwear, cut-resistant gloves, proper lifting equipment and simple training are not just safety measures; they are mod management. Our articles on workers’ compensation for Florida restaurants and how Florida distributors can reduce workers’ compensation claims cover the controls that make the biggest difference.
Open Claims and Reserves Count
The mod uses the value of each claim at the time the data is reported, and for open claims that value is the carrier’s reserve, its estimate of what the claim will eventually cost. A claim reserved high and left open can raise the mod even if it eventually closes for much less. Asking the carrier to review reserves on old open claims, and working to close claims when an employee has recovered, can affect the next mod calculation.
A return-to-work program helps in the same way. An employee who comes back on modified or light duty, instead of staying home, keeps a claim smaller and shortens it, which lowers the amount that counts against the mod. The program does not need to be complicated, but it does need to be in place before the injury.
Check the Worksheet for Errors
NCCI produces an experience rating worksheet that shows the payroll, class codes and claims used to calculate your mod. It is worth reviewing every year, because errors happen and they are not corrected unless someone asks. Common problems include payroll reported in the wrong class code, claims that belong to a different business, claims that were closed or reduced but still show the old reserve, recoveries from a third party that were never credited, and payroll from the wrong policy period. Your agent can request the worksheet and help you challenge an error through the carrier.
Ownership changes also matter. When a business is sold, merged or restructured, NCCI rules decide whether the old mod transfers to the new entity. Starting a new company does not automatically produce a fresh 1.00, and trying to escape a bad mod by changing the business name or structure can be treated as an attempt to avoid the rules.
Why Customers Ask for Your Mod
General contractors, property managers, facility owners and government agencies increasingly use the mod as a prequalification requirement, because they see it as a simple measure of how safely a business operates. A contractor with a mod above the customer’s limit may not be allowed to bid, whatever its price or reputation. Because the mod looks back several years, a business that wants this kind of work has to start managing the number well before it plans to bid. Our article on what your contract requires from your insurance covers the other insurance requirements those customers set, and our guide to workers’ compensation for Florida contractors explains why contractors feel this most.
When the Mod Is Too High
A high mod makes the premium more expensive, and above a certain point it can make a business hard to place in the standard market. The fix takes time, because the mod looks back several years, but the steps are clear: reduce the frequency of small injuries, report claims promptly so they are handled well, get injured employees back to work on modified duty, close old claims, and check the worksheet for errors. For some small businesses with a poor mod, joining a professional employer organization can change the economics in the meantime; see our article on PEO workers’ comp in Florida.
What Business Owners Should Confirm
-
Does your business qualify for its own mod, and what is it this year?
-
Have you reviewed the experience rating worksheet for errors in payroll, class codes or claims?
-
Are any old claims still open with reserves that no longer reflect their real value?
-
Do you have a return-to-work program for injured employees?
-
Are minor injuries reported promptly and managed, rather than ignored?
-
Do your customers or the contracts you want to bid on require a maximum mod?
-
If your business changed ownership or structure, has the mod been handled correctly?
