What describes the operation of insurers that collect premiums and reserve a portion to pay claims?

The operation of insurers that collect premiums and set aside a portion of those collections to pay claims is characteristic of commercial insurers. Commercial insurers are for-profit entities that provide coverage to consumers by accepting premiums in exchange for risk transfer. They must carefully manage their finances, reserving a specific amount of their income (premiums) to fulfill their obligations when claims arise. This process involves actuarial science to estimate potential losses and ensure they maintain sufficient reserves without jeopardizing the company’s financial stability.

In contrast, mutual insurers, while also involved in the collection of premiums, operate under a model where insured members share the ownership and profits. Non-profit insurers typically aim to provide coverage and not serve profit-driven objectives, thus distinguishing them from commercial insurers. Public insurers, often government entities, focus on providing insurance coverage for specific needs rather than as a commercial enterprise. Therefore, it is the structure and purpose of commercial insurers that aligns with the description provided in the question.
