4 NDM Annual Quantities

(c) between 12:00 and 16:00 during the Gas Flow Day (and at any further Demand Forecast Update between 16:00 and the end of the Gas Flow Day), for the purposes of the Operator determining Nomination Quantities for Users NDM Offtake Renominations, as:

(EUC(D) / EUC(AAQ)) * AQ * SF(f1)

(d) after the Gas Flow Day, for the purposes of determining Users UDQO, as:

(EUC(D) / EUC(AAQ)) * AQ * SF(a)

where for the purposes of paragraphs (a), (b), (c), and (d) in respect of the relevant Gas Flow Day:

EUC(D) is the estimated aggregate demand estimate for the EUC to which the NDM Supply Meter Point belongs;

EUC(AAQ) is the sum of the AQs of NDM Supply Meter Points for the EUC to which the NDM Supply Meter Point belongs;

AQ is the prevailing Annual Quantity for the NDM Supply Meter Point; and

SF is the Scaling Factor calculated in accordance with paragraph 3.3.

3.3 For the purposes of paragraph 3.2 in relation to a Gas Flow Day:

(a) the Scaling Factor "SF(f)" is:

ForD / ModD

(b) the Scaling Factor "SF(f1)" is:

ForD1 / ModD

(c) the Scaling Factor "SF(a)" is:

ActD / ModD

3.4 The Operator will determine (at each relevant time) for each User the aggregate demand of the NDM Supply Meter Point Group as the sum of the Supply Meter Point Demand of the User’s Registered NDM Supply Meter Points.

4 NDM Annual Quantities

4.1 The Operator shall determine, in accordance with this paragraph 4, the Annual Quantity for each NDM Supply Meter Point for each Gas Year and notify the relevant Registered User thereof prior to the commencement of the relevant Gas Year.

4.2 For the purposes of paragraph 4 the "Relevant Period" in respect of a Gas Year is the 24month period up to and including 10 August in the Preceding Year.

4.3 In respect of a Gas Year and:

(a) a new NDM Supply Meter Point, the Annual Quantity for the Gas Year in which the
