The Vade Mecum is a compiled-style document that brings together all elements relevant to the implementation of the SGP. In this edition, we are changing the style of the document with a view to streamlining the information presented and facilitating readability of the explanations of EU rules and of the institutional processes of budgetary surveillance. The streamlining of the document does not mean that the Commission is changing the rules. The document focuses on describing current EU fiscal rules. Technical details for hands-on experts, such as numerical examples and reporting tables, are provided on the Commission’s website. Selected relevant economic concepts are recapped in boxes. The purpose of these changes is to make the document accessible, not only for experts and organisations working on public finance issues in Member States but also for non-specialists.
