5 Individual NDM Reconciliation

4.2 The DM Reconciliation Quantity for a Day shall be:

(a) determined as the DM Check Read Reconciliation Volume (determined in accordance with Section M paragraph 7.4(b)) or the Failed Daily Read Reconciliation Volume (determined in accordance with Section M paragraph 6.3(b)) multiplied by the applicable calorific value for the Day; and

(b) in the case of a Daily Read Error Day in respect of which Section M paragraph 8.10 applies, the Error Revised Quantity.

4.3 The DM Reconciliation Quantity is:

(a) negative where (in accordance with Sections M paragraph 6 and M paragraph 7) the DM Check Reconciliation Volume or Failed Daily Read Reconciliation Volume is negative, and positive where it is positive; and

(b) in respect of a Daily Read Error Day, negative where the Error Revised Quantity is less than the Metered Quantity derived from the original Daily Meter Readings for the Daily Read Error Day and positive where the Error Revised Quantity is greater than the Metered Quantity derived from the original Daily Meter Readings for the Daily Read Error Day.

4.4 The DM Reconciliation Commodity Charge for a Day shall be established by multiplying the DM Reconciliation Quantity by the Applicable Commodity Rate for such Day.

5 Individual NDM Reconciliation

5.1 In respect of a Larger NDM Supply Meter Point, the "Individual NDM Reconciliation Quantity" is the amount by which the Metered Quantity differs from the sum of the Supply Meter Point Demand (determined in accordance with Section F paragraph 3) for the NDM Supply Meter Point for each Day in the Meter Reading Period.

5.2 The Individual NDM Reconciliation Quantity shall be established by:

(a) dividing the Supply Meter Point Demand for each Day in the Meter Reading Period in respect of the NDM Supply Meter Point by the relevant calorific value for that Day to determine the 'daily NDM volume';

(b) aggregating the daily NDM volumes for all days in the Meter Reading period to determine the 'aggregate NDM volume';

(c) dividing the Metered Volume by the aggregate NDM volume to determine the 'NDM reconciliation factor';

(d) multiplying the Supply Meter Point Demand for each Day in the Meter Reading Period by the NDM reconciliation factor to determine the 'daily metered quantity';

(e) subtracting the daily metered quantity from the Supply Meter Point Demand for each Day in the Meter Reading Period to establish the 'daily reconciliation quantity'; and

(f) aggregating the daily reconciliation quantities for all Days in the Meter Reading Period.
