Assigned risk frequently asked questions

Quotes are estimates and are subject to change. Several factors could change between the time the quote is received and the time the policy is issued, such as rates, experience modification factors, and payroll exposures.

Work with your broker or agent to determine whether you can obtain coverage from a voluntary carrier, to decide whether it is advisable for any executive officers of the corporation to exclude themselves from coverage, and to verify that all class codes and estimated payrolls are accurate. Also, be sure to obtain current copies of workers compensation certificates of insurance for any vendors or subcontractors performing work for you so that our premium auditors can exclude those payroll entries from final premium calculations.

Experience modification factors are used to adjust workers compensation premiums based on your business’ loss experience. The National Council on Compensation Insurance (NCCI) or your state rating bureau calculates any experience modification factors.

You can find contact information on the NCCI website.

Each of the following states has its own rating bureau website:

Delaware: Delaware Compensation Rating Bureau
Indiana: Indiana Compensation Rating Bureau
Massachusetts: The Workers Compensation Rating and Inspection Bureau
Michigan: Compensation Advisory Organization of Michigan
New Jersey: New Jersey Compensation Rating and Inspection Bureau
North Carolina: North Carolina Rate Bureau
Pennsylvania: Pennsylvania Compensation Rating Bureau
Wisconsin: Wisconsin Compensation Rating Bureau

The purpose of a premium audit is to calculate your final premium. When your policy was issued, your premium was based on estimated exposures. By auditing your policies, we can ensure that your business pays the correct premium based on actual exposures.

The auditor will be able to obtain most of the necessary information from one or more of the following:

• Payroll, sales journals, and/or summaries
• Individual earnings records or workers compensation employee earnings summaries
• Cash disbursements journal
• General ledger
• Quarterly tax reports
• Financial statements
• Subcontractor cost and certificates

The audit process will be much easier and could work to your advantage if you maintain detailed records. Your payroll records should indicate what types of jobs each employee performed during your policy term and how much they were paid.

For construction or erection operations, the payroll of an employee may be allocated to authorized construction classifications if proper records are maintained. If you do not maintain such a breakdown, we must place the entire payroll of the employee into the highest-rated classification that describes any part of the employee’s work. Keep in mind that we can only divide an employee’s payroll between more than one classification using actual wages, not according to a ratio or percentage split of the payroll.
