The table below shows the rest of the 20 largest insurance companies in the world by market cap. 

The market cap data was pulled from this website. Also referred to as market cap, market capitalization is the total market value of a company’s outstanding shares owned by stockholders. In simple terms, it is how much the company is worth as determined by the stock market. Market cap is calculated by multiplying the number of outstanding shares by the current market value of a single share. 

Investors typically use market capitalization to determine a company’s size rather than its sales or total assets. The figure is also used to evaluate a company’s financial performance against other firms of various sizes. 

Determining a firm’s market cap is important, especially for the investing community, because companies with larger market capitalization are often seen as safer investments as they are also mostly established industry players with a longer history in the business.
