Understanding the CLM Structure

The CLM is organized into a series of divisions, sections, and rules, providing a clear and systematic framework for accessing the information contained within.

Divisions and Sections

The CLM is divided into various divisions, each dedicated to a specific line of commercial insurance. These divisions typically cover major categories such as⁚

• Automobile⁚ This division encompasses rules and rating information related to commercial auto insurance, including coverage for vehicles used in business operations.
• General Liability⁚ This section focuses on liability exposures faced by businesses, covering risks such as bodily injury, property damage, and advertising injury.
• Commercial Property⁚ This division addresses the insurance needs of commercial properties, including coverage for buildings, contents, and business interruption.
• Workers Compensation⁚ This section covers the requirements for workers compensation insurance, which provides benefits to employees injured on the job.

Within each division, the CLM is further subdivided into sections, each dedicated to a specific aspect of the insurance line. For instance, the General Liability division might have sections covering⁚

• General Liability Coverage Forms⁚ This section details the standard policy forms used for general liability insurance, outlining coverage provisions and exclusions.
• Rating Rules and Classifications⁚ This section provides guidance on how to classify businesses based on their specific liability risks, and how to determine appropriate premiums.
• Loss Costs⁚ This section contains the statistical data used to calculate the expected cost of losses for different liability exposures, forming the basis for premium calculations.

This hierarchical structure allows insurers to quickly and efficiently locate the relevant information for the specific coverage they are seeking to underwrite.

Rating Rules and Classifications

The CLM employs a comprehensive system of rating rules and classifications to ensure that premiums accurately reflect the risks associated with different businesses. This system is crucial for maintaining fairness and equity in the insurance market.

Rating rules specify the factors that influence premium calculations, such as⁚

• Business Type⁚ The nature of the business, its operations, and the products or services it offers play a significant role in determining its risk profile.
• Location⁚ The geographical location of the business can affect its exposure to various risks, such as natural disasters, crime, or traffic congestion.
• Size and Revenue⁚ The size of the business, its revenue, and the number of employees can impact the potential financial losses it may face.
• Safety Practices⁚ The business’s safety procedures and risk management practices are crucial factors in assessing its overall risk profile.

Classifications group businesses with similar risk characteristics, ensuring that premiums are consistent for businesses with comparable levels of exposure. The CLM provides detailed descriptions of various business classifications, allowing insurers to accurately categorize policyholders based on their specific operations and risk factors.

This system of rating rules and classifications ensures that premiums are fair and reflective of the risks associated with each business, promoting a balanced and equitable insurance market.

Loss Costs and Premium Determination

The CLM serves as the foundation for determining premiums in commercial lines insurance by providing loss costs, which represent the anticipated cost of claims for specific types of risks. These loss costs are derived from historical data and industry trends, reflecting the average cost of claims for businesses within a particular classification.

Insurers use these loss costs as a starting point for calculating premiums, adjusting them based on the specific risk factors associated with individual businesses. The CLM also outlines various rating rules and factors that insurers must consider, such as⁚

• Deductibles⁚ The amount the insured is responsible for paying before the insurer covers the remaining portion of the claim.
• Coinsurance⁚ A requirement for the insured to carry a certain percentage of insurance coverage to minimize moral hazard and encourage risk management.
• Rating Credits⁚ Discounts or reductions in premiums for businesses that implement safety measures or have a proven history of low claims.
• Rating Surcharges⁚ Additional charges applied to premiums for businesses with high risk profiles or a history of frequent claims.

By combining loss costs with these rating rules and factors, insurers can arrive at a premium that reflects the unique risk profile of each insured business. This process ensures that premiums are both fair and accurate, reflecting the potential cost of claims and the risk management practices of the business.
