The UK Listing Rules (UKLR) are a set of regulations applicable to any company listed on a United Kingdom stock exchange, subject to the oversight of the Financial Conduct Authority (FCA). The UK Listing Rules set out mandatory standards for any company wishing to list its shares or securities for sale to the public, including principles on executive pay and the requirement to comply or explain noncompliance with the UK Corporate Governance Code, the requirements of information in a prospectus before an initial public offering of shares, new share offers, rights issues, disclosure of price sensitive information, or takeover bids for companies.
