Examples of public limited companies include BP p.l.c., Barclays PLC and Marks & Spencer Group plc, reports Yahoo! Finance. PLC is a legal term that defines registered limited liability corporations in the United Kingdom that may be bought and sold by the public.
According to Investopedia, owners and management are granted limited liability with a public liability company. Only PLC companies are granted listing on the London Stock Exchange; however, there are some PLC companies listed on other exchanges in other countries, and PLCs with equity not listed on any exchange at all. The equity of PLC companies may be entirely privately held almost always, though not exclusively, by other PLCs.
