EXPOSURE
On the PCE, GME defines the exposure of each Participant based on the risk of potential failure to fulfil the obligation related to the payment (settlement) of the CCT (Fee for the assignment of rights of use of transmission capacity) and requests that such exposure is covered by adequate guarantees.
Depending on the operations to be made, the exposure will be calculated for each flow day and then cumulatively aggregated by settlement date. Therefore, during the stage of request for registration on the PCE and in the following stages until settlement, GME carries out financial adequacy checks aimed at verifying that the posted guarantee is adequate with respect to the single exposure held (see Technical Rule no. 04 PCE).
More specifically, when a Participant submits or confirms a registration on the PCE for
- a transaction increasing, in absolute value, the net sell position of the forward injection account,
- a transaction increasing, in absolute value, the net sell or buy position of a forward storage account,
- a CET demand bid pertaining to zonal injection portfolios associated with a forward withdrawal account for the step-down margin only,
an exposure will be generated equal to the product between the quantities offered and the estimated CCT, taking into account the chargeable VAT.
Once the PUN Index GME is known and the portfolios have been assigned, the exposure for
- CET supply offers registered on the related forward injection account,
- CET supply offers and demand bids registered on the related forward storage account,
- CET demand bids pertaining to zonal injection portfolios associated with a forward withdrawal account for the step-down margin only, registered on the related forward account,
will be equal to the value of the CCT actually due, given by the product between the net quantity traded and the real unit value of the CCT, calculated as the difference between the zonal price and the PUN Index GME, and taking into account the chargeable VAT. The credit positions, in this phase, define the possibility of offsetting the debit exposures that have the same settlement date.
