'Price' and ‘Notional Amount’ fields in eRR REMIT Table 1 Trade Entry screen (index reporting)
The ACER Open Letter advises that the reporting party should the definitions in the TRUM regarding the field (No. 38). There have been cases where zero value has been reported with no index.
The TRUM state:
This field should be left blank for trades that do not have a known price at the time of the trade. The same applies to any contracts which have a floating leg, e.g. gas/electricity financial swaps not reported under EMIR but reportable under REMIT. For example: in April, market participant (A) enters into an electricity financial swap contract for the month of July. Market participant (A) is the seller of the swap. Market participant (A) sells the forward fixed leg in April and it buys the spot price (based on a reference price) in July. For the fixed leg, the forward price is known today, but the spot price is not known until the end of July. In this case, this field should be left blank.
As you are reporting an index deal, you will not know the value at the time of reporting and therefore these fields should be left blank.
If you do know the value of the trade then it should not be reported as an index deal.
