Relevant dates

  • March 29, 2017 – The UK formally notified the European Council of its intention to withdraw from the EU

Key impacts

Public and private companies should consider disclosing the:

  • UK’s notice of withdrawal and the nature of the company’s activities that could be affected;
  • uncertainty involved in evaluating the effect on financial statements of the loss of tax exemptions and reliefs available to EU members only; and
