Public limited company
From ACT Wiki
UK.
(Plc, plc or PLC).
A public limited company is one which may - subject to complying with certain conditions - be allowed to offer its shares or other securities for sale to the public or to a section of the public.
To protect the public, public limited companies are therefore subject to greater regulation and requirements to report fuller financial information within shorter timeframes, compared with private companies.
They must use names including 'Plc', 'plc' or 'PLC' to disclose clearly that they are a public limited company.
