Use this element for increases expressed as percentages in inputs not expressed as percentages—for example, a 2 per cent increase in cash flows. Also use this element for increases expressed in percentage points in inputs expressed as percentages—for example, a 2 percentage point increase in an 8 per cent discount rate to a discount rate of 10 per cent. Do not use this element for relative changes in inputs expressed as percentages—for example, a 2 per cent increase in an 8 per cent discount rate to a discount rate of 8.16 per cent (ie multiplied by 1.02). In such cases, create extension elements. Use this element for decreases expressed as percentages in inputs not expressed as percentages—for example, a 2 per cent decrease in cash flows. Also use this element for decreases expressed in percentage points in inputs expressed as percentages—for example, a 2 percentage point decrease in an 8 per cent discount rate to a discount rate of 6 per cent. Do not use this element for relative changes in inputs expressed as percentages—for example, a 2 per cent decrease in an 8 per cent discount rate to a discount rate of 7.84 per cent (ie multiplied by 0.98). In such cases, create extension elements. A positive or negative XBRL value can be entered for this element. Refer to the standard element label to determine the correct sign.
