Annual Loss Expectancy (ALE) is a critical metric used in risk management and security assessments to estimate the potential financial losses an organization might face due to specific risks over the course of a year. The calculation of ALE fundamentally relies on two primary components: impact and frequency.

Impact refers to the financial loss that could be incurred if a risk were to materialize. This loss could stem from various factors, such as operational disruptions, property damage, or liabilities resulting from security incidents. Understanding the impact allows organizations to prioritize risks according to their potential financial ramifications.

Frequency, on the other hand, indicates the likelihood of a risk occurring within a specified timeframe, typically one year. This quantification helps in predicting how often a particular loss event may happen, thus enabling a more accurate calculation of ALE.

By combining impact (the cost of potential losses) and frequency (the rate at which these losses might occur), organizations can formulate a more robust understanding of their risk landscape, allowing for better-informed decision-making regarding risk mitigation strategies and resource allocation.

This approach contrasts with other options, which do not directly address the integral formula for calculating ALE. For instance, while risk management and system effectiveness are vital in creating an overarching security strategy, they do not specifically determine the annual loss
