This document is a technical report detailing the FAIR Model, a framework for analyzing risk factors. It serves as a concise reference for understanding the structure of the FAIR Model, which decomposes risk into fundamental components to facilitate better measurement and management. The report outlines the definitions and relationships of various factors within the model, including Loss Event Frequency (LEF), Loss Magnitude (LM), and their subcomponents. It addresses common misperceptions about the FAIR Model and clarifies that this document does not provide a how-to guide for implementation, as that information is available in other publications. The FAIR Model can quantify risk in both financial and non-financial terms, making it versatile for different applications. This report is intended for individuals seeking to utilize the FAIR Model for effective risk management without delving into extensions like FAIR-CAM or FAIR-MAM, which are covered in separate documents.
