What does the principle of independence refer to in the context of insurance?

The principle of independence in the context of insurance refers to the notion that unrelated events do not influence each other. This is particularly crucial in the realm of risk management and the calculation of premiums. When events are independent, the occurrence of one event does not affect the probability of another event happening. This principle enables insurers to effectively assess and manage risks by treating each insured event as a distinct occurrence.

For example, if an insurance company is underwriting policies for property damage and each policyholder's property is located in different areas with no correlation in risk factors (like natural disasters), the company can treat claims from these policyholders independently. This mitigates the risk of large losses stemming from a single event impacting multiple policies simultaneously.

Understanding the independence of events is fundamental for insurers as it impacts everything from premium calculations to reserve requirements and overall risk assessment strategies.
