The European Securities and Markets Authority (ESMA) has published and updated a set of Questions and Answers covering European Market Infrastructure Regulation (EMIR), the European crowdfunding service providers for business regime (ECSPR), and Markets in Financial Instruments Directive II (MiFID II) secondary markets. Under EMIR, the Q&As address assessing whether issues are significant for the purposes of Error and Omission Notifications and the reporting of Settlement Rate Options. For ECSPR, ESMA covers the calculation of the threshold referred to in point (c) of Article 1(2) and how to treat crowdfunding carried out through multiple offers. For MiFID II secondary markets, the Q&As cover open interest thresholds in energy derivatives.
