The structure of Solvency II follows the four-level Lamfalussy process, as modified by the Lisbon Treaty. As such, Solvency II will ultimately comprise of upwards of fifty European regulatory texts. In addition, insurers will also need to refer to national law and regulatory rules which implement aspects of the Directive.

This document attempts to explain the various components of the Solvency II regime and present all relevant regulatory texts within a single, easy to navigate, compendium.
