Financial liability is any liability that is:
(a) a contractual obligation:
(i) to deliver cash or another financial asset to another entity; or
(ii) to exchange financial assets or financial liabilities with another entity under conditions that are potentially unfavourable to the entity; or
(b) a contract that will or may be settled in the entity’s own equity instruments and is:
(i) a non-derivative for which the entity is or may be obliged to deliver a variable number of the entity’s own equity instruments; or
(ii) a derivative that will or may be settled other than by the exchange of a fixed amount of cash or another financial asset for a fixed number of the entity’s own equity instruments. For this purpose the entity’s own equity instruments do not include puttable financial instruments that are classified as equity instruments in accordance with paragraphs 16A and 16B of IAS 32, instruments that impose on the entity an obligation to deliver to another party a pro rata share of the net assets of the entity only on liquidation and are classified as equity instruments in accordance with paragraphs 16C and 16D of IAS 32, or instruments that are contracts for the future receipt or delivery of the entity’s own equity instruments.
As an exception, an instrument that meets the definition of a financial liability is classified as an equity instrument if it has all the features and meets the conditions in paragraphs 16A and 16B or paragraphs 16C and 16D of IAS 32.
