A bar above a term indicates that it is calculated as the average over three years: t, t-1 and t-2.
 

(Abs) is the absolute value of the terms within the brackets. The absolute value of net items must be calculated first for each financial year, and the average of the past three consecutive financial years must be calculated based on the absolute value of net items for each financial year.
 

The definitions for each of the components of the BI are provided in Annexure 1.
