What is an Actuary? - A Brief Overview

In general, actuaries assess the financial consequences of risks and use mathematics, statistics and financial theory to analyze and determine the financial impact of uncertain future events.

Pension actuaries suggest methods to eliminate or reduce damage to parties if a future event occurs. They are primarily concerned with the payment of benefits, including death benefits, from a pension plan. Pension actuaries also calculate the required amount of an employer’s annual contribution to a defined benefit plan to ensure that current and future plan benefits are available to the participants.
