How IAS 33 requires the earnings figure to be determined for the purpose of calculating earnings per share.

According to IAS 33, the earnings figure for EPS purposes should be the profit for the year attributable to the
equity shareholders of the group.
In practice, this normally consists of profit after tax, after exceptional items, after any preference dividends are
declared, but before any equity dividends.
It must also be adjusted to exclude non-controlling interests, if any, in that profit.
