In order to be authorised, the issuer must open a specific bank or post office account, in accordance with article L. 1271-11, into which the funds received as consideration for the transfer of the securities are paid, to the exclusion of all others. The amount in this account, equal to the equivalent value of the special payment instruments in circulation, guarantees the reimbursement to the parties involved of the special payment instruments validly issued and used. This counterparty must have an outstanding balance of at least 300,000 euros. The account is initially funded to at least this amount.
An authorised issuer is authorised to open several of these accounts in one or more banking establishments or post office cheque centres, provided that their combined balance exceeds the minimum amount at all times. He may make transfers from one specific account to another. Under the responsibility of the issuer, the sums credited to the specific accounts of the special payment voucher referred to in B of article L. 1271-1 may be temporarily invested provided that their amount remains immediately realisable at any time at their initial face value.
In the event of falsification, alteration, destruction or theft during dispatch of the special payment instruments referred to in B of article L. 1271-1, this specific reserve account may be used on condition that its amount is restored no later than seven clear days after all or part of it has been mobilised.
