§  61.49   Supporting information to be submitted with letters of transmittal
for tariffs of carriers subject to price cap regulation.

   (a) Each price cap tariff filing must be accompanied by supporting
   materials sufficient to calculate required adjustments to each PCI,
   API, and SBI pursuant to the methodologies provided in § § 61.45, 61.46,
   and 61.47, as applicable.

   (b) Each price cap tariff filing that proposes rates that are within
   applicable bands established pursuant to § 61.47, and that results in an
   API value that is equal to or less than the applicable PCI value, must
   be accompanied by supporting materials sufficient to establish
   compliance with the applicable bands, and to calculate the necessary
   adjustment to the affected APIs and SBIs pursuant to § § 61.46 and 61.47,
   respectively.

   (c) Each price cap tariff filing that proposes rates above the
   applicable band limits established in § § 61.47 (e) must be accompanied
   by supporting materials establishing substantial cause for the proposed
   rates.

   (d) Each price cap tariff filing that proposes rates that will result
   in an API value that exceeds the applicable PCI value must be
   accompanied by:

   (1) An explanation of the manner in which all costs have been allocated
   among baskets; and

   (2) Within the affected basket, a cost assignment slowing down to the
   lowest possible level of disaggregation, including a detailed
   explanation of the reasons for the prices of all rate elements to which
   costs are not assigned.

   (e) Each price cap tariff filing that proposes restructuring of
   existing rates must be accompanied by supporting materials sufficient
   to make the adjustments to each affected API and SBI required by
   § § 61.46(c) and 61.47(d), respectively.

   (f)(1) [Reserved]

   (2) Each tariff filing submitted by a price cap local exchange carrier
   that introduces a new loop-based service, as defined in § 61.3(pp) of
   this part--including a restructured unbundled basic service element
   (BSE), as defined in § 69.2(mm) of this chapter, that constitutes a new
   loop-based service--that is or will later be included in a basket, must
   be accompanied by cost data sufficient to establish that the new
   loop-based service or unbundled BSE will not recover more than a just
   and reasonable portion of the carrier's overhead costs.

   (3) A price cap local exchange carrier may submit without cost data any
   tariff filings that introduce new services, other than loop-based
   services.

   (4) A price cap local exchange carrier that has removed its corridor or
   interstate ntraLATA toll services from its interexchange basket
   pursuant to § 61.42(d)(4)(ii), may submit its tariff filings for
   corridor or interstate intraLATA toll services without cost data.

   (g) Each tariff filing submitted by a price cap local exchange carrier
   that introduces a new loop-based service or a restructured unbundled
   basic service element (BSE), as defined in § 69.2(mm) of this chapter,
   that is or will later be included in a basket, or that introduces or
   changes the rates for connection charge subelements for expanded
   interconnection, as defined in § 69.121 of this chapter, must also be
   accompanied by:

   (1) The following, including complete explanations of the bases for the
   estimates.

   (i) A study containing a projection of costs for a representative 12
   month period; and

   (ii) Estimates of the effect of the new tariff on the traffic and
   revenues from the service to which the new tariff applies, the
   carrier's other service classifications, and the carrier's overall
   traffic and revenues. These estimates must include the projected
   effects on the traffic and revenues for the same representative 12
   month period used in paragraph (g)(1)(i) of this section.

   (2) Working papers and statistical data. (i) Concurrently with the
   filing of any tariff change or tariff filing for a service not
   previously offered, the issuing carriers must file the working papers
   containing the information underlying the data supplied in response to
   paragraph (h)(1) of this section, and a clear explanation of how the
   working papers relate to that information.

   (ii) All statistical studies must be submitted and supported in the
   form prescribed in § 1.363 of the Commission's rules.

   (h) Each tariff filing submitted by a price cap local exchange carrier
   that introduces or changes the rates for connection charge subelements
   for expanded interconnection, as defined in § 69.121 of this chapter,
   must be accompanied by cost data sufficient to establish that such
   charges will not recover more than a just and reasonable portion of the
   carrier's overhead costs.

   (i) [Reserved]

   (j) For a tariff that introduces a system of density pricing zones, as
   described in § 69.123 of this chapter, the carrier must, before filing
   its tariff, submit a density pricing zone plan including, inter alia,
   documentation sufficient to establish that the system of zones
   reasonably reflects cost-related characteristics, such as the density
   of total interstate traffic in central offices located in the
   respective zones, and receive approval of its proposed plan.

   (k) [Reserved]

   (l) On each page of cost support material submitted pursuant to this
   section, the issuing carrier shall indicate the transmittal number
   under which that page was submitted.
