actuary

n. one who calculates insurance risks and premiums according to statistical probabilities

An actuary is a business professional who deals with the financial impact of risk and uncertainty.Actuaries have 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 events and quantify the contingent outcomes in order to minimize losses, both emotional and financial, associated with uncertain undesirable events. Since many events, such as death, cannot be totally avoided, it is helpful to take measures to minimize their financial impact when they occur. These risks can impact both sides of the balance sheet, and require asset management, liability management, and valuation skills. Analytical skills, business knowledge and understanding of human behavior and the vagaries of information systems are required to design and manage programs that control risk .
