. The initials PLC after a UK or Irish company name indicate that it is a public limited company, a type of limited company whose shares may be offered for sale to the public. When a new company is incorporated in either England and Wales or Scotland, it must be registered with Companies House, which is an Executive Agency of the Department of Trade and Industry. In the Republic of Ireland, the equivalent body is the Companies Registration Office, Ireland. Northern Ireland also has a Registrar of Companies.
The designation plc, Plc or PLC (either form is acceptable) was introduced in the UK by the Companies Act 1980, and in the Republic of Ireland by the Companies (Amendment) Act 1983. In the Republic of Ireland, the initials "CPT" (for the Irish cuideachta phoiblí theoranta) may be used instead, but this is rarely the case. Welsh companies may use the letters "ccc" (for cwmni cyfyngedig cyhoeddus) in similar fashion. Certain public limited companies incorporated under special legislation (mainly nationalised concerns) are exempt from carrying the letters PLC, CCC, or CPT. When forming (or creating) a PLC there must be: at least £50,000-worth (Republic of Ireland: €38,092.14) of share capital of which at least 25% must have been paid for. Two shareholders, two directors, one of whom may also be the company secretary. A certificate of entitlement (the trading certificate) to do business and borrow capital.
