What type of insurers do stock and mutual insurers both fall under?

Stock and mutual insurers both fall under the category of private insurers. Private insurers are entities that provide insurance products and services to individuals and businesses rather than operating under the auspices of government programs.

Stock insurers are owned by shareholders, who may receive dividends based on the company's profitability, while mutual insurers are owned by their policyholders, who share in the profits through dividends or reduced premiums. Both types of insurers operate on a profit basis and are primarily focused on serving the insurance needs of the public. This classification as private insurers distinguishes them from public insurance programs, which are government-sponsored and designed to provide coverage for specific populations or needs.
