ARM 38.5.2713. FILING REQUIREMENT OF DETARIFFED SERVICES

(1) Any telecommunications provider offering regulated telecommunications service detariffed under ARM 38.5.2712 shall maintain sufficient internal documentation to demonstrate that the revenues from detariffed operations are in excess of the incremental cost of providing the service. To the extent that detariffed operations do not cover incremental costs the commission will not allow those costs to be recovered through the rates of regulated services.
