Actuaries model and measure the financial risk of future events for agencies and corporations that provide insurance, often using software like Excel and SQL. Actuaries are the business professionals most essential to the insurance industry. Their duties include maintaining daily correspondence with clients, programming or implementing risk management software, and strategizing events that bring financial risk to companies and their products. Actuaries price insurance policies and advise corporations on how to meet regulatory standards and balance capital. They lead busy professional lives, and on a daily basis they may review, prepare, and present reports to clients and executives whose financial well-being depends on the results of actuarial science. Four actuary specializations are property-casualty, life, health, and pension.
