DEFUNCT

It is when a company declared its bankruptcy and ceased to be exit. It can happen even if the company is publicly traded or if it is private. If the company was publicly traded, it will be delisted from the exchange where it was listed, and its stock will be worth nothing. In exceptional situations, the Securities and Exchange Commission does allow the stock of a defunct company to continue to trade for a period of time, but this is as a result of legal technicalities rather than a particular right or privilege.
