The Irish Stock Exchange (ISE) has formed a new corporate structure and has become a public limited company.
The company said that all operations, services and processes previously undertaken by The Irish Stock Exchange Limited are now being undertaken by The Irish Stock Exchange plc.
The change in corporate structure has been approved by the Central Bank of Ireland.
Deirdre Somers, Chief Executive of the ISE, said: "We are excited to start this new chapter in the Irish Stock Exchange’s 200 year history.
"This new legal structure brings the ISE more in line with corporate norms which we believe is more appropriate for the successful, diverse international business that the ISE has become. This change also provides us with greater flexibility for our future development which is of benefit to all our customers and stakeholders."
