Premiums vary significantly by industry and business size. Insurance premiums are largely determined by the coverages chosen by the insured. Risk exposure can differ from high risk to low risk, and depending on the class of business, this can also have a tremendous impact on pricing.
Other factors that affect pricing include carrier rates, loss history, underwriting factors, experience, agency representation, industry averages, market conditions, reinsurance availability, reserve regulations, and negotiation of terms and conditions, among others.
