INSURANCE MARKET CLASSIFICATION
Class of business definition
Class of business is an insurance classification that groups policies by category, such as motor, property, liability or marine.
In practice, this means in insurance terms, a class of business (or sometimes simply “class”) denotes a category of insurance, such as motor. A class of business is also known as a line of business and the term “sub-class” refers to more refined categories of major classes. This gives insurers, brokers, reinsurers and risk managers a shared way to discuss the concept when reviewing policies, claims, regulation or market data.
This term is especially useful in insurance market analysis, policy wording and risk transfer decisions. It helps users interpret insurance terminology consistently across markets, policies and risk data. It also helps users compare how insurance is structured, regulated, priced or claimed across different markets.
Class of business is closely related to line of business, commercial lines, personal lines and liability insurance. Linking these concepts together helps build a clearer glossary structure and gives readers a stronger understanding of how individual insurance terms connect within wider international insurance practice.
