The suspension of shares is a temporary halt in the trading of a company's stock on a stock exchange. This usually occurs when there is significant uncertainty or concern surrounding the company's affairs, making it difficult to accurately price its shares.

Common reasons for share suspension include:

Financial difficulties:
Bankruptcy or insolvency proceedings.

Legal or regulatory issues:
Investigations by regulatory bodies (e.g., SEC) or pending lawsuits or legal actions.

Corporate restructuring:
Mergers, acquisitions, or demergers or major changes in business operations or strategy.

Significant events or announcements:
Company news that may impact the value of its shares.

Delay in submitting financial statements:
Failure to meet regulatory deadlines for financial reporting or accounting irregularities.

Excessive volatility:
Extreme price fluctuations may also lead to shares being halted from trade.

Share suspensions can be either voluntary or mandatory, depending on the circumstances. During a suspension, shares cannot be bought or sold on the stock exchange. It's important to note that share suspensions often last longer than temporary halts in trading, as they are usually implemented to address more significant underlying issues.
