Actuaries are business professionals who deal with the financial impact of risk and uncertainty. Actuaries are highly trained experts with a deep understanding of financial security systems, their reasons for being, their complexity, their mathematics, and the way they work. They evaluate the likelihood of future events and design creative ways to quantify the contingent outcomes in order to minimize losses associated with uncertain undesirable events. These risks can impact both sides of the balance sheet and require asset management, liability management, and valuation skills. It takes a combination of strong analytical skills, business knowledge and understanding of both human behavior and the vagaries of information systems to design and manage programs that control risk. Actuaries work in a number of insurance disciplines, which may be classified as life, health, pensions, annuities, and asset management, social welfare programs, property, casualty, liability, general insurance and reinsurance.
