Disclosure time left is minimal - they are required by law
Definition Material information is any information relating to the business and affairs of an issuer that results in or would reasonably be expected to result in a significant change in the market price or value of any of the issuer's securities. Material information consists of both material facts and material changes relating to the business and affairs of an issuer. The market price or value of an issuer's securities is sometimes affected by, in addition to material information, the existence of rumours and speculation. Where this is the case, the issuer may be required to make an announcement as to whether such rumours and speculation are factual or not.
