The Telecommunications (Interconnection) (Carrier Pre-selection) Regulations 1999

50A.8  Subject to the provisions in sub-paragraphs 50A.8(1) and (2), the Director may, at any time, or on request, make a determination specifying the level of the surcharges referred to in paragraphs 50A.6 and 50A.7 and the period of time for which they shall apply. U.K.

1. Any determination specifying costs or charges made under paragraph 50A.8 shall:

1. unless some other cost-basis shall have been substituted by the Director, be based upon the Licensee’s long-run incremental costs of providing Carrier Pre-selection Facilities;

2. be calculated on the basis of information provided by the Licensee to the Director in accordance with related provisions of this Licence and in response to any written request by the Director which shall be responded to within the reasonable time limits specified in the request;

2. The following provisions shall also apply with respect to any determination made under paragraph 50A.8.

1. the Director may determine that a cost is not reasonable if he considers that the Licensee could at the relevant time have used lower costs methods in implementing the relevant aspect of any Carrier Pre-selection Facility and in that event the Director may disallow the item of cost in question in whole or in part as appropriate;

2. in the event that, in making any determination under paragraph 50A.8 the Director considers that the cost basis of any charges for a Carrier Pre-selection Facility in any preceding period has been inaccurately estimated, he shall make an adjustment to such a charge determined by him as he considers is appropriate for rectifying the matter.
