As your business operations change, so may your insurance premium. At Liberty Mutual Insurance, we conduct premium audits to make sure that the premium you pay for your coverage accurately reflects your business's operations over the policy period. An audit doesn't always mean a higher premium. In fact, it could be a positive experience for your company because it may lower your premium.
The purpose is to determine actual exposures and classes of operation for the coverage we provided. A premium audit protects both of us. Our auditors undertake this review to learn if you overpaid for coverage, in which case your final bill will be reduced. If you underpaid, your final bill may be adjusted upward. Finally, if risks, coverages, and exposures match what we projected, your final bill remains the same.
In addition, information filed as part of unit statistical data reporting determines your experience modification as well as establishes appropriate premium rates for each state.
Premium Audits are completed either electronically or in-person.
