AASB 132, para. 11:
"A financial asset is any asset that is:
(a) cash;
(b) an equity instrument of another entity;
(c) a contractual right:
(i) to receive cash or another financial asset from
another entity; or
(ii) to exchange financial assets or financial
liabilities with another entity under conditions
that are potentially favourable to the entity; or
(d) 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 receive 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
classified as equity instruments in accordance
with paragraphs 16A and 16B, 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, or instruments
that are contracts for the future receipt or
delivery of the entity’s own equity instruments.
...
An equity instrument is any contract that evidences a residual
interest in the assets of an entity after deducting all of its
liabilities."
