Stock insurance company

An insurer owned by shareholders who supply its capital and receive its profits, as opposed to one owned by the people it insures.

Also called: stock insurer, stock company, publicly traded insurer, shareholder-owned insurer

A stock insurance company is owned by shareholders. They put up the capital that backs the policies, elect the board, and receive the profits as dividends or share-price gains. Some stock insurers are publicly traded, such as Allstate, Travelers and Progressive. Others are privately held, or are subsidiaries of a larger group whose parent is the public company.

Policyholders in a stock company own nothing. Homeowners policies from stock insurers are usually non-participating: you pay a fixed premium and the policy does not pay dividends, whatever the company earns. That does not make the company more or less likely to pay claims. What the structure changes is who bears the risk. Shareholders absorb losses first, and the company can raise more capital by selling stock or debt, which helps after a heavy catastrophe year.

Shareholder ownership also means pressure to earn a return, which shows up in rate requests, underwriting changes and decisions about which states to stay in. Reading the combined ratio shows whether a company is making or losing money on its policies.

Ownership alone says little about service or reliability. Judge a stock insurer by its rating, complaint record and claims reputation, and see how stock, mutual and reciprocal insurers compare.
