Then we will have to deal with possible scenarii for management of yearly PTRs: Legal and regulatory risks for transfer of activity (invoice, settlement, reimbursement, UIOSI) to CASC of PTRs allocated by TSOs Pros Legally irreproachable Only one SPOC for all PTRs starting from 1 st April 2011 Not totally legally irreproachable but in line with users interests

18. Analysis of impacts if we success to transfer yearly to CASC from 1st April 2011 The overlapping between Bank Guarantee provided to TSOs and the Bank Account given to CASC has not an huge impact on Users. The full payment of Yearly PTRs for Jan, Feb and Mar in January (payment in advance) CASC should invoice Yearly PTRS for April in May 2011 (payment ex-post) Users can riduce the Bank Guarantee with TSOs before deposit money on CASC Bank Account 1st April 2011 Go Live CASC expire of Bank Guarantee Live CASC
