Second one is to overcome problems from macroeconomic including low economic growth and low interest rate, fluctuating foreign currency exchange rate, and problems from population composition change and longer longevity. One of the possible ways to control the risks that life insurance companies face is using derivatives. Traditionally life insurance companies use reinsurance to hedge their inherent risks.
