(a) This part establishes procedures and methodologies for Commission prescription of an authorized unitary interstate exchange access rate of return and individual rates of return for the interstate exchange access rates of certain carriers pursuant to §65.102. This part shall apply to those interstate services of local exchange carriers as the Commission shall designate by rule or order, except that all local exchange carriers shall provide to the Commission that information which the Commission requests for purposes of conducting prescription proceedings pursuant to this part.
(b) Local exchange carriers subject to §§61.41 through 61.49 of this chapter are exempt from the requirements of this part with the following exceptions:
(1) Except as otherwise required by Commission order, carriers subject to §§61.41 through 61.49 of this chapter shall employ the rate of return value calculated for interstate access services in complying with any applicable rules under parts 36 and 69 that require a return component;
(2) Carriers subject to §§61.41 through 61.49 of this chapter shall be subject to §65.600(d);
(3) Carriers subject to §§61.41 through 61.49 of this chapter shall continue to comply with the prescribed rate of return when offering any services specified in §61.42(f) of this chapter unless the Commission otherwise directs; and
(4) Carriers subject to §§61.41 through 61.49 of this chapter shall comply with Commission information requests made pursuant to §65.1(a).
[60 FR 28543, June 1, 1995]
(a) All interstate exchange access carriers, their customers, and any member of the public may participate in rate of return proceedings to determine the authorized unitary interstate exchange access or individual interstate exchange access rates of return authorized pursuant to §65.102.
(b) Participants shall state in their initial pleading in a prescription proceeding whether they wish to receive service of documents and other material filed in the proceeding. Participants that wish to receive service by hand on the filing dates when so required by this part 65 shall specify in their initial pleading in a prescription proceeding, as specified in §65.103 (b) and (c), an agent for acceptance of service by hand in the District of Columbia. The participant may elect in its pleading to receive service by mail or upon an agent at another location. When such an election is made, other participants need not complete service on the filing date, and requests for extension of time due to delays in completion of service will not be entertained.
[60 FR 28544, June 1, 1995]
(a) Whenever the Commission determines that the monthly average yields on ten (10) year United States Treasury securities remain, for a consecutive six (6) month period, at least 150 basis points above or below the average of the monthly average yields in effect for the consecutive six (6) month period immediately prior to the effective date of the current prescription, the Commission shall issue a notice inquiring whether a rate of return prescription according to this part should commence. This notice shall state:
(1) The deadlines for filing initial and reply comments regarding the notice;
(2) The cost of debt, cost of preferred stock, and capital structure computed in accordance with §§65.302, 65.303, and 65.304; and
(3) Such other information as the Commission may deem proper.
(b) Based on the information submitted in response to the notice described in §65.101(a), and on any other information specifically identified, the Commission may issue a notice initiating a prescription proceeding pursuant to this part.
(c) The Chief, Wireline Competition Bureau, may issue the notice described in §65.101(a).
[60 FR 28544, June 1, 1995, as amended at 67 FR 13229, Mar. 21, 2002]
(a) Exclusion from unitary treatment will be granted for a period of two years if the cost of capital for interstate exchange service is so low as to be confiscatory because it is outside the zone of reasonableness for the individual carrier's required rate of return for interstate exchange access services.
(b) A petition for exclusion from unitary treatment and for individual treatment must plead with particularity the exceptional facts and circumstances that justify individual treatment. The showing shall include a demonstration that the exceptional facts and circumstances are not of transitory effect, such that exclusion for a period of a least two years is justified.
(c) A petition for exclusion from unitary treatment and for individual treatment may be filed at any time. When a petition is filed at a time other than that specified in §65.103(b)(2), the petitioner must provide compelling evidence that its need for individual treatment is not simply the result of short-term fluctuations in the cost of capital or similar events.
(a) Rate of return submissions listed in §65.103 (b)(1) and (c) may include any relevant information, subject to the page limitations of §65.104. The Chief, Wireline Competition Bureau, may require from carriers providing interstate services, and from other participants submitting rate of return submissions, data, studies or other information that are reasonably calculated to lead to a full and fair record.
(b) In proceedings to prescribe an authorized unitary rate of return on interstate access services, interested parties may file direct case submissions, responses, and rebuttals. Direct case submissions shall be filed within sixty (60) calendar days following the effective date of a Commission notice initiating a rate of return proceeding pursuant to §65.101(b). Rate of return submissions responsive to the direct case submissions shall be filed within sixty (60) calendar days after the deadline for filing direct case submissions. Rebuttal submissions shall be field within twenty-one (21) calendar days after the deadline for filing responsive submissions.
(c) Petitions for exclusion from unitary treatment and for individual treatment may be filed on the same date as the deadline for filing responsive rate of return submissions. Oppositions shall be filed within 35 calendar days thereafter. Rebuttal submissions shall be filed within 21 calendar days after the deadline for filing responsive submissions.
(d) An original and 4 copies of all rate of return submissions shall be filed with the Secretary.
(e) The filing party shall serve a copy of each rate of return submission, other than an initial submission, on all participants who have filed a designation of service notice pursuant to §65.100(b).
Rate of return submissions, including all argument, attachments, appendices, supplements, and supporting materials, such as testimony, data and documents, but excluding tables of contents and summaries of argument, shall be subject to the following double spaced typewritten page limits:
(a) The direct case submission of any participant shall not exceed 70 pages in length.
(b) The responsive submission of any participant shall not exceed 70 pages in length.
(c) The rebuttal submission of any participant shall not exceed 50 pages in length.
(d) Petitions for exclusion from unitary treatment shall not exceed 70 pages in length. Oppositions to petitions for exclusion shall not exceed 50 pages in length. Rebuttals shall not exceed 35 pages in length.
(a) Participants shall file with each rate of return submission copies of all information, including studies, financial analysts' reports, and any other documents relied upon by participants or their experts in the preparation of their submission. Information filed pursuant to this paragraph for which protection from disclosure is sought shall be filed subject to protective orders which shall be duly granted by the Chief, Wireline Competition Bureau, for good cause shown.
(b) Participants may file written interrogatories and requests for documents directed to any rate of return submission and not otherwise filed pursuant to §65.105(a). The permissible scope of examination is that participants may be examined upon any matter, not privileged, that will demonstrably lead to the production of material, relevant, decisionally significant evidence.
(c) Discovery requests pursuant to §65.105(b), including written interrogatories, shall be filed within 14 calendar days after the filing of the rate of return submission to which the request is directed. Discovery requests that are not opposed shall be complied with within 14 calendar days of the request date.
(d) Oppositions to discovery requests made pursuant to §65.105(b), including written interrogatories, shall be filed within 7 calendar days after requests are filed. The Chief, Wireline Competition Bureau, shall rule upon any such opposition. Except as stayed by the Commission or a Court, any required response to a discovery request that is opposed shall be provided within 14 calendar days after release of the ruling of the Chief, Wireline Competition Bureau.
(e) An original and 4 copies of all information described in §65.105(a) and all requests, oppositions, and responses made pursuant to §65.105 (a), (b) and (d) shall be filed with the Secretary.
(f) Service of requests, oppositions, and responses made pursuant to §65.105 (b) and (d) shall be made upon all participants who have filed a designation of service notice pursuant to §65.100(b). Service of requests upon participants who have filed designation of service notices pursuant to §65.100(b) shall be made by hand on the filing dates thereof.
(a) Sections 65.301 through 65.303 specify the calculations that are to be performed in computing cost of debt, cost of preferred stock, and financial structure weights for prescription proceedings. The calculations shall determine, where applicable, a composite cost of debt, a composite cost of preferred stock, and a composite financial structure for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000. The calculations shall be based on data reported to the Commission in FCC Report 43-02. (See 47 CFR 43.21). The results of the calculations shall be used in the represcription proceeding to which they relate unless the record in that proceeding shows that their use would be unreasonable.
(b) Excluded from cost of capital calculations made pursuant to §65.300 shall be those sources of financing that are not investor supplied, or that are otherwise subtracted from a carrier's rate base pursuant to Commission orders governing the calculation of net rate base amounts in tariff filings that are made pursuant to section 203 of the Communications Act of 1934, 47 U.S.C. 203, or that were treated as “zero cost” sources of financing in section 450 and subpart G of this part 65. Specifically excluded are: accounts payable, accrued taxes, accrued interest, dividends payable, deferred credits and operating reserves, deferred taxes and deferred tax credits.
The cost of equity shall be determined in represcription proceedings after giving full consideration to the evidence in the record, including such evidence as the Commission may officially notice.
[60 FR 28545, June 1, 1995]
The formula for determining the cost of debt is equal to:
“Total Annual Interest Expense” is the total interest expense for the most recent year for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000 of this chapter.
“Average Outstanding Debt” is the average of the total debt outstanding at the beginning and at the end of the most recent year for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000 of this chapter.
[81 FR 24344, Apr. 25, 2016]
The formula for determining the cost of preferred stock is:
“Total Annual Preferred Dividends” is the total dividends on preferred stock for the most recent two years for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000. “Proceeds from the Issuance of Preferred Stock” is the average of the total net proceeds from the issuance of preferred stock for the most recent two years for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000.
“Book Value of particular component” is the total of the book values of that component for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000.
“Book Value of Debt + Book Value of Preferred Stock + Book Value of Equity” is the total of the book values of all the components for all local exchange carriers with annual revenues equal to or above the indexed revenue threshold as defined in §32.9000.
(a) The composite weighted average cost of capital is the sum of the cost of debt, the cost of preferred stock, and the cost of equity, each weighted by its proportion in the capital structure of the telephone companies.
(b) Unless the Commission determines to the contrary in a prescription proceeding, the composite weighted average cost of debt and cost of preferred stock is the composite weight computed in accordance with §65.304 multiplied by the composite cost of the component computed in accordance with §65.301 or §65.302, as applicable. The composite weighted average cost of equity will be determined in each prescription proceeding.
[60 FR 28546, June 1, 1995]
In a prescription proceeding, the final determinations of the cost of equity, cost of debt, cost of preferred stock and their capital structure weights shall be accurate to two decimal places.
(b) Gains and losses related to the disposition of plant in service items, shall be handled as follows:
(1) Gains related to property sold to others and leased back under finance leases for use in telecommunications services shall be recorded in Account 4300, Other long-term liabilities and deferred credits, and credited to Account 6563, Amortization expense—tangible, over the amortization period established for the finance lease;
(2) Gains or losses related to the disposition of land and other nondepreciable items recorded in Account 7100 (Other operating income and expense) shall be included in net income for ratemaking purposes, but adjusted to reflect the relative amount of time such property was used in regulated operations and included in the rate base; and
(3) Proceeds related to the disposition of property depreciated on a group basis and used jointly in regulated and nonregulated activities, including sale-leaseback arrangements for property depreciated on a group basis, shall be credited to the related reserves and attributed to regulated and nonregulated in proportion to the accumulated regulated and nonregulated depreciation for that group.
(c) Gains or losses related to the disposition of property that was never included in the rate base shall not be considered for ratemaking purposes.
(d) Except for the allowance for funds used during construction, reasonable charitable deductions and interest related to customer deposits, the amounts recorded as nonoperating income and expenses and taxes (Accounts 7300 and 7400) and interest and related items (Account 7500) and extraordinary items (Account 7600) shall not be included unless this Commission specifically determines that particular items recorded in those accounts shall be included.
[53 FR 1029, Jan. 15, 1988, as amended at 60 FR 12139, Mar. 6, 1995; 67 FR 5702, Feb. 6, 2002; 69 FR 53652, Sept. 2, 2004; 84 FR 4733, Feb. 19, 2019]
The net income methodology specified in §65.450 shall be utilized by all interexchange carriers that are so designated by Commission order.
(a) Subpart E shall apply to those interstate communications common carriers and exchange carriers that are so designated by Commission order.
(b) Each local exchange carrier or group of affiliated carriers which is not subject to §§61.41 through 61.49 of this chapter and which has filed individual access tariffs during the preceding enforcement period shall file with the Commission within three (3) months after the end of each calendar year, an annual rate of return monitoring report which shall be the enforcement period report. Reports shall be filed on the appropriate report form prescribed by the Commission (see §1.795 of this chapter) and shall provide full and specific answers to all questions propounded and information requested in the currently effective report form. The number of copies to be filed shall be specified in the applicable report form. At least one copy of the report shall be signed on the signature page by the responsible officer. A copy of each report shall be retained in the principal office of the respondent and shall be filed in such a manner as to be readily available for reference and inspection. Final adjustments to the enforcement period report shall be made by September 30 of the year following the enforcement period to ensure that any refunds can be properly reflected in an annual access filing.
(c) Each interexchange carrier subject to §§61.41 through 61.49 shall file with the Commission, within three (3) months after the end of each calendar year, the total interstate rate of return for that year for all interstate services subject to regulation by the Commission. Each such filing shall include a report of the total revenues, total expenses and taxes, operating income, and the rate base. A copy of the filing shall be retained in the principal office of the respondent and shall be filed in such manner as to be readily available for reference and inspection.
(d)(1) Each local exchange carrier or group of affiliated carriers subject to §§61.41 through 61.49 of this chapter shall file with the Commission within three (3) months after the end of each calendar year a report of its total interstate rate of return for that year. Such filings shall include a report of the total revenues, total expenses and taxes, operating income, and the rate base. Reports shall be filed on the appropriate form prescribed by the Commission (see §1.795 of this chapter) and shall provide full and specific answers to all questions propounded and information requested in the currently effective form. The number of copies to be filed shall be specified in the applicable report form. At least one copy of the report shall be retained in the principal office of the respondent and shall be filed in such manner as to be readily available for reference and inspection.
(2) Each local exchange carrier or group of affiliated carriers subject to §§61.41 through 61.49 of this chapter shall file with the Commission within fifteen (15) months after the end of each calendar year a report reflecting any corrections or modifications to the report filed pursuant to paragraph (d)(1) of this section. Reports shall be filed on the appropriate form prescribed by the Commission (see §1.795 of this chapter) and shall provide full and specific answers to all questions propounded and information requested in the currently effective form. The number of copies to be filed shall be specified in the applicable report form. At least one copy of the report shall be retained in the principal office of the respondent and shall be filed in such manner as to be readily available for reference and inspection.
[52 FR 274, Jan. 5, 1987, as amended at 54 FR 19844, May 8, 1989; 55 FR 42385, Oct. 19, 1990; 56 FR 21617, May 10, 1991; 62 FR 5166, Feb. 4, 1997]
(a) The maximum allowable rate of return for any exchange carrier's earnings on any access service category shall be determined by adding a fixed increment of four-tenths of one percent of the exchange carrier prescribed rate of return.
(b) The maximum allowable rate of return for any exchange carrier's overall interstate earnings for all access service categories shall be determined by adding a fixed increment of one-quarter of one percent to the exchange carrier prescribed rate of return.
(c) The maximum allowable rate of return for rates filed by local exchange carrier subject to §61.50 of this chapter, shall be determined by adding a fixed increment of one and one-half percent to the carriers prescribed rate of return.
[51 FR 11034, Apr. 1, 1986, as amended at 58 FR 36149, July 6, 1993; 60 FR 28546, June 1, 1995]
For both exchange and interexchange carriers subject to this part, interstate earnings shall be measured over a two year period to determine compliance with the maximum allowable rate of return. The review periods shall commence on January 1 in odd-numbered years and shall end on December 31 in even-numbered years.
(a) For exchange carriers, earnings shall be measured separately for each access service category for purposes of determining compliance with the maximum allowable rate of return. The access service categories shall be: an aggregated category consisting of Special Access, §69.113, and Contribution Charges for Special Access Expanded Interconnection, §69.122; Connection Charges for Expanded Interconnection, §69.121; Common Line, §§69.104-69.105; and an aggregated category consisting of Line Termination, §69.106, Intercept, §69.108, Local Switching, §69.107, Transport, §§69.110-69.112, 69.124, 69.125, and Information, §69.109. The Billing and Collection access element shall not be included in any access service category for purposes of this part. The Commission will also separately review exchange carrier overall interstate earnings subject to this part for determining compliance with the maximum allowable rate of return determined by §65.700(b).
(b) For exchange carriers, earnings shall be measured for purposes of determining compliance with the maximum allowable rates of return separately for each study area; provided, however, that if the carrier has filed or concurred in access tariffs aggregating costs and rates for two or more study areas, the earnings will be determined for the aggregated study areas rather than for each study area separately. If an exchange carrier has not utilized the same level of study area aggregation during the entire two-year earnings review period, then the carrier's earnings will be measured for the entire two-year period on the basis of the tariffs in effect at the end of the second year of the two-year review period; provided, however, that if tariffs representing a higher level of study area aggregation were not in effect for at least eight months in the second year, then the carrier's earnings will be measured on the basis of the study area level of aggregation in effect for the majority of the two-year period; provided further, that any carrier that was not a member of the National Exchange Carrier Association or other voluntary pools for both years of the two-year review period will have its earnings reviewed individually for the full two-year period.
[51 FR 11034, Apr. 1, 1986, as amended at 57 FR 54719, Nov. 20, 1992; 58 FR 48763, Sept. 17, 1993; 60 FR 28546, June 1, 1995]
Source: 53 FR 1029, Jan. 15, 1988, unless otherwise noted.
The rate base shall consist of the interstate portion of the accounts listed in §65.820 that has been invested in plant used and useful in the efficient provision of interstate telecommunications services regulated by this Commission, minus any deducted items computed in accordance with §65.830.
As used in this subpart “account xxxx” means the account of that number kept in accordance with the Uniform System of Accounts for Telecommunications Companies in 47 CFR part 32.
[82 FR 20843, May 4, 2017]
(a) Telecommunications plant. The interstate portion of all assets summarized in Account 2001 (Telecommunications Plant in Service) and Account 2002 (Property Held for Future Use), net of accumulated depreciation and amortization, and Account 2003 (Telecommunications Plant Under Construction), and, to the extent such inclusions are allowed by this Commission, Account 2005 (Telecommunications Plant Adjustment). Any interest cost for funds used during construction capitalized on assets recorded in these accounts shall be computed in accordance with the procedures in Sec. 32.2000(c)(2)(x) of this chapter.
(b) Material and supplies. The interstate portion of assets summarized in Account 1220.1 (Material and Supplies).
(c) Noncurrent assets. The interstate portion of Class B Rural Telephone Bank stock contained in Account 1410 and the interstate portion of assets summarized in Account 1410 (Other Noncurrent Assets) and Account 1438 (Deferred Maintenance, Retirements and Deferred Charges), only to the extent that they have been specifically approved by this Commission for inclusion (Note: The interstate portion of assets summarized in Account 1410 should not include any amounts related to investments, sinking funds or unamortized debt issuance expense). Except as noted above, no amounts from accounts 1406 through 1500 shall be included.
(d) Cash working capital. The average amount of investor-supplied capital needed to provide funds for a carrier's day-to-day interstate operations. Carriers may calculate a cash working capital allowance either by performing a lead-lag study of interstate revenue and expense items or by using the formula set forth in paragraph (e) of this section. Carriers, in lieu of performing a lead-lag study or using the formula in paragraph (e) of this section, may calculate the cash working capital allowance using a standard allowance which will be established annually by the Chief, Wireline Competition Bureau. When either the lead-lag study or formula method is used to calculate cash working capital, the amount calculated under the study or formula may be increased by minimum bank balances and working cash advances to determine the cash working capital allowance. Once a carrier has selected a method of determining its cash working capital allowance, it shall not change to an optional method from one year to the next without Commission approval.
(e) In lieu of a full lead-lag study, carriers may calculate the cash working capital allowance using the following formula.
(1) Compute the weighted average revenue lag days as follows:
(i) Multiply the average revenue lag days for interstate revenues billed in arrears by the percentage of interstate revenues billed in arrears.
(ii) Multiply the average revenue lag days for interstate revenues billed in advance by the percentage of interstate revenues billed in advance. (Note: a revenue lead should be shown as a negative lag.)
(iii) Add the results of paragraphs (e)(1) (i) and (ii) of this section to determine the weighted average revenue lag days.
(2) Compute the weighted average expense lag days as follows:
(i) Multiply the average lag days for interstate expenses (i.e., cash operating expenses plus interest) paid in arrears by the percentage of interstate expenses paid in arrears.
(ii) Multiply the average lag days for interstate expenses paid in advance by the percentage of interstate expenses paid in advance. (Note: an expense lead should be shown as a negative lag.)
(iii) Add the results of paragraphs (e)(2) (i) and (ii) of this section to determine the weighted average expense lag days.
(3) Compute the weighted net lag days by deducting the weighted average expense lag days from the weighted average revenue lag days.
(4) Compute the percentage of a year represented by the weighted net lag days by dividing the days computed in paragraph (e)(3) of this section by 365 days.
(5) Compute the cash working capital allowance by multiplying the interstate cash operating expenses (i.e., operating expenses minus depreciation and amortization) plus interest by the percentage computed in paragraph (e)(4) of this section.

(a) The following items shall be deducted from the interstate rate base.
(1) The interstate portion of deferred taxes (Accounts 4100 and 4340).
(2) The interstate portion of customer deposits (Account 4040).
(3) The interstate portion of other long-term liabilities in (Account 4300 Other long-term liabilities and deferred credits) that were derived from the expenses specified in Sec. 65.450(a).
(4) The interstate portion of other deferred credits in (Account 4300 Other long-term liabilities and deferred credits) to the extent they arise from the provision of regulated telecommunications services. This shall include deferred gains related to sale-leaseback arrangements.
(b) The interstate portion of deferred taxes, customer deposits and other deferred credits shall be determined as prescribed by 47 CFR part 36.
(c) The interstate portion of other long-term liabilities included in (Account 4300 Other long-term liabilities and deferred credits) shall bear the same proportionate relationships as the interstate/intrastate expenses which gave rise to the liability.
[54 FR 9049, Mar. 3, 1989, as amended at 62 FR 15118, Mar. 31, 1997; 67 FR 5703, Feb. 6, 2002]
