The effect of a situation opposite to dilution. Specifically, it denotes an increase in earnings per share (EPS) or a decrease in loss per share that is associated with:

• actual or assumed conversion of convertible instruments (e.g., convertible bonds);
• exercise of options and warrants; or
• issuance of ordinary shares.

Antidilutive securities are financial instruments that an entity issues to existing or potential shareholders (holders of its common stock/ ordinary share), conferring on them the right to convert these securities into common stock. This would result in an increase in the earning per share or a decrease in the loss per share of the entity.
