Samsung Life is Korea's largest insurer. It has a market share of life-insurance premiums of 22%, compared with 12% each for its two biggest rivals. It owns 72% of listed Samsung Card and 30% of equity-method affiliate Samsung Securities. It also owns close to 15% of sister company Samsung Fire & Marine Insurance, Korea's largest nonlife insurer, and owns 8.5% of Samsung Electronics, a stake that is worth well in excess of its own market cap.
