Bankruptcy or Reorganization:

A company's shares may be suspended from trading during a bankruptcy filing or a company reorganization, pending the resolution of the corporate action. In this case, a shareholder's holding will be converted to escrow shares and then converted back to their original form if any equity remains in the company after the completion of the bankruptcy or reorganization process.
