This document provides a summary of a webinar presentation about the financial rules of Horizon Europe compared to Horizon 2020. The presentation covered key changes in terminology, personnel cost calculation using a daily rate approach, budgeting versus reporting, project-based remuneration replacing additional remuneration, rules around in-kind contributions, and a new System and Process Audit that could reduce ex-post audits for low-risk beneficiaries. The presentation also discussed internally invoiced goods and services actual costs instead of a flat rate, no limits on exceeding maximum EC contributions, and a Mutual Insurance Mechanism replacing the Guarantee Fund. Q&A was taken at the end to address questions received in advance.
