How will corporate actions affect trading in the overnight session?

A pending corporate action may temporarily halt a security from trading. This is a typical response to ensure the action is processed correctly. Please note, dividends are issued to individuals who have purchased a stock on or before the ex-dividend date. Because transactions made in the overnight session are marked as T+1, purchasing a stock in the overnight session on the ex-dividend date will not entitle you to that stock’s upcoming dividend.
