Accounting Separation 1) Where the Authority has determined that a Wholesale Roaming service provider has SMP in a relevant market for wholesale mobile access and call origination services, the Wholesale Roaming provider shall keep separate accounts, as if the Wholesale Roaming service were in fact carried out by a legally independent company, so as to identify all elements of cost and revenue attributable to such services. 2) The Authority may, at its own discretion, adopt directives prescribing how the account separation referred to in Sub-Article (1) of this Article shall be implemented.
