Personal vs. Commercial Insurance

A comparison of personal and commercial lines of property-casualty insurance: coverage, pricing, and data structure.

Intro

Insurance covers two fundamental types of risk: property and liability.

Property Risk: Financial loss suffered directly by the insured.
Liability Risk: Financial loss incurred when the insured is responsible for damages to a third party.

Property insurance protects assets from being destroyed, damaged, or stolen.

Scope of Coverage: This typically includes both the physical structure (the building) and the personal property inside it (the contents).
Types of Loss: When an incident occurs, the owner generally suffers in two distinct ways:
- Direct Loss: The physical damage to, or loss of value of, the property itself.
- Indirect Loss: The financial impact resulting from the inability to use the property (e.g., temporary living expenses or lost business income).
Perils (Causes of Loss): The specific events that trigger a property loss are known as “perils.” These are often categorized as:
- Physical and Environmental Perils: Events such as fire, windstorms, explosions, or damage caused by aircraft.
- Human-Made Perils: Events like theft, which encompasses specific crimes like burglary and robbery.
- Policy is inclusive (lists perils covered) or exclusive (covers everything except what is listed).
Personal insurance is insurance purchased for nonbusiness risk exposures.
Commercial insurance is insurance purchased for business risk exposures.

Building insurance: if the business owner is a tenant they don’ need to insure the building
Contents insurance: even though the building is on rent, business owners personally owns the contents: stock, furnitures, tools…
