§ 54.901   Calculation of Interstate Common Line Support.

   (a) Interstate Common Line Support available to a rate-of-return carrier
   shall equal the Common Line Revenue Requirement per Study Area as calculated
   in accordance with part 69 of this chapter minus:

   (1) The study area revenues obtained from end user common line charges at
   their allowable maximum as determined by § § 69.104(n) and 69.104(o) of this
   chapter;

   (2) The carrier common line charge revenues to be phased out pursuant to
   § 69.105 of this chapter;

   (3) The special access surcharge pursuant to § 69.114 of this chapter;

   (4)  The line port costs in excess of basic analog service pursuant to
   § 69.130 of this chapter; and

   (5) Any Long Term Support for which the carrier is eligible or, if the
   carrier ceased participation in the NECA common line pool after October 11,
   2001, any Long Term Support for which the carrier would have been eligible
   if it had not ceased its participation in the pool.

   (b) The per-line Interstate Common Line Support available to a competitive
   eligible telecommunications carrier serving lines in a study area served by
   a  rate-of-return  carrier shall be calculated by the Administrator as
   follows:

   (1) If the rate-of-return carrier has disaggregated the support it receives
   in the study area pursuant to § 54.315, the Administrator shall calculate the
   amount of Interstate Common Line Support targeted to each disaggregation
   zone  by  the  rate-of-return carrier (targeted Interstate Common Line
   Support). If the rate-of-return carrier has chosen not to disaggregate its
   support for a study area pursuant to § 54.315, then the entirety of its
   Interstate  Common Line Support for the study area shall be considered
   targeted Interstate Common Line Support for purposes of performing the
   calculations in this section.

   (2)  In  each  disaggregation  zone or undisaggregated study area, the
   Administrator shall calculate the Average Interstate Common Line Support by
   dividing  the rate-of-return carrier's targeted Interstate Common Line
   Support by its total lines served.

   (3)  The Administrator shall then calculate the Interstate Common Line
   Support available to the competitive eligible telecommunications carrier for
   each line it serves for each customer class in a disaggregation zone or
   undisaggregated study area by the following formula:

   (i) If the Average Interstate Common Line Support is greater than $2.70
   multiplied by the number of residential and single-line business lines
   served  by  the  rate-of-return  carrier in the disaggregation zone or
   undisaggregated study area, then:

   (A) Interstate Common Line Support per Multi-Line Business Line = (Average
   Interstate  Common  Line Support − $2.70 × residential and single-line
   business lines served by the rate-of-return carrier) ÷ (total lines served
   by the rate-of-return carrier); and

   (B) Interstate Common Line Support per Residential and Single-Line Business
   Line = Interstate Common Line Support per Multi-Line Business Line + $2.70.

   (ii) If the Average Interstate Common Line Support is less than or equal to
   $2.70 multiplied by residential and single-line business lines served by the
   rate-of-return carrier in the disaggregation zone or undisaggregated study
   area, but greater than $0, then:

   (A) Interstate Common Line Support per Multi-Line Business Line = $0; and

   (B) Interstate Common Line Support per Residential and Single-Line Business
   Line = Average Interstate Common Line Support ÷ residential and single line
   business lines served by the rate-of-return carrier.

   (iii) If the Average Interstate Common Line Support is equal to $0, then the
   competitive eligible telecommunications carrier shall receive no Interstate
   Common  Line  Support  for lines served in that disaggregation zone or
   undisaggregated study area.

   (4) Beginning January 1, 2012, competitive eligible telecommunications
   carriers shall not receive Interstate Common Line Support pursuant to this
   subpart and will instead receive support consistent with § 54.307(e).

   (c) Beginning January 1, 2012, for purposes of calculating the amount of
   Interstate Common Line Support determined pursuant to paragraph (a) of this
   section that a non-price cap carrier may receive, the corporate operations
   expense  allocated to the Common Line Revenue Requirement, pursuant to
   § 69.409 of this chapter, shall be limited to the lesser of:

   (1) The actual average monthly per-loop corporate operations expense; or

   (2)  The  portion  of the monthly per-loop amount computed pursuant to
   § 36.621(a)(4)(iii) of this chapter that would be allocated to the interstate
   Common Line Revenue Requirement pursuant to § 69.409 of this chapter.

   (d) Support After December 31, 2011. Notwithstanding paragraph (a) of this
   section, beginning January 1, 2012, no carrier that is a rate-of-return
   carrier, as that term is defined in § 54.5 affiliated with a price cap local
   exchange carrier, as that term is defined in § 61.3(aa) of this chapter,
   shall receive support under this subpart.
