The Association of Corporate Treasurers first issued their useful briefing note on ‘European Regulation of OTC Derivatives’ in January 2013 and have been updating it regularly, see here. 

Other useful weblinks on the European situation on OTC derivatives include:

• ACT EMIR – frequently asked questions for non‐financial counterparties
• ISDA EMIR documentation and guidance
• ESMA Questions and Answers on EMIR
• FCA main EMIR page
• FCA links to European source legislation
• UTI information
• Approved issuers of LEIs
• EU registered Trade Repositories.

You’ll need these links as the regulations on European OTC derivatives will certainly change again.
