211 This is the sum of the volume multiplied by pre-approved unit rate for suburbs/postcodes where the AER has approved a unit rate plus the volume multiplied by the actual unit rate for suburbs/postcodes where the AER has not approved a unit rate (subject to the AER assessing that the unit rate actually incurred was prudent and efficient).

212 Where volumes have been undertaken in suburbs/postcodes where the AER has not pre-approved a unit rate, the AER will apply a residual unit rate to these volumes. The residual unit rate will be calculated as the total approved expenditure for historical volumes less the expenditure incurred for mains replacement actually undertaken in the suburbs/postcodes included in the AER’s approved historical expenditure, divided by, the total approved historical volume less the volume undertaken in the suburbs/postcodes included in the AER’s approved historical expenditure.
